1
00:00:00,320 --> 00:00:02,880
Speaker 1: Brought to you by the reinvented two thousand twelve camera.

2
00:00:03,200 --> 00:00:08,800
Speaker 1: It's ready. Are you get in touch with technology? With

3
00:00:08,920 --> 00:00:14,520
Speaker 1: tech Stuff from how stuff works dot com. Hey there, everybody,

4
00:00:14,600 --> 00:00:17,160
Speaker 1: welcome to tech Stuff. My name is Chris Polette. I'm

5
00:00:17,160 --> 00:00:19,440
Speaker 1: an editor here at how stuff works dot com and

6
00:00:19,520 --> 00:00:22,680
Speaker 1: with me as usual as senior writer Jonathan Strickland. Hey there,

7
00:00:23,360 --> 00:00:26,800
Speaker 1: and today we're going to talk about that pesky source

8
00:00:26,840 --> 00:00:30,680
Speaker 1: of electricity in your mobile phone, portable camera, portable computer

9
00:00:31,200 --> 00:00:36,080
Speaker 1: three player. That's the rechargeable battery. Yes, the the the

10
00:00:36,120 --> 00:00:39,960
Speaker 1: device to which we are all slaves. How many times, Chris,

11
00:00:40,000 --> 00:00:42,680
Speaker 1: have you been out and about and you were about

12
00:00:42,720 --> 00:00:46,000
Speaker 1: to rely upon your favorite mobile gadget only to discover

13
00:00:46,320 --> 00:00:50,200
Speaker 1: your battery had completely drained away and you couldn't get

14
00:00:50,200 --> 00:00:53,479
Speaker 1: it to work no matter what. That's thousands of times, Jonathan.

15
00:00:53,520 --> 00:00:56,720
Speaker 1: It's a real source of frustration. Yeah, it is for

16
00:00:56,760 --> 00:00:59,400
Speaker 1: me to um. And so we wanted to talk about

17
00:00:59,760 --> 00:01:01,400
Speaker 1: kind of what you need to do in order to

18
00:01:01,480 --> 00:01:04,640
Speaker 1: keep your battery in the best possible working order. There's

19
00:01:04,640 --> 00:01:07,040
Speaker 1: a lot of conflicting information out there, as it turns out,

20
00:01:07,080 --> 00:01:09,959
Speaker 1: in fact, there was there was one thing that both

21
00:01:10,040 --> 00:01:12,760
Speaker 1: Chris and I believed was you know, that was the

22
00:01:12,840 --> 00:01:15,280
Speaker 1: right thing to do all the time. That turned out

23
00:01:15,280 --> 00:01:19,319
Speaker 1: to not necessarily be true. Right, Yeah, that's true. And

24
00:01:19,680 --> 00:01:22,080
Speaker 1: just as a little bit of background, the thing that

25
00:01:22,400 --> 00:01:26,520
Speaker 1: prompted me to suggest this topic for a podcast is

26
00:01:27,360 --> 00:01:29,880
Speaker 1: I get complaints all the time about people who say

27
00:01:29,920 --> 00:01:33,440
Speaker 1: their cell phonwner MP three player dies and I asked them,

28
00:01:33,480 --> 00:01:37,520
Speaker 1: have you ever conditioned your battery or or calibrated your battery?

29
00:01:37,520 --> 00:01:40,600
Speaker 1: And they go, what? And the thing is that I

30
00:01:40,600 --> 00:01:42,600
Speaker 1: don't think a lot of people know, and I don't

31
00:01:42,640 --> 00:01:46,039
Speaker 1: think a lot of manufacturers include information that says, hey, look,

32
00:01:46,080 --> 00:01:48,280
Speaker 1: every once in a while, your machine is not going

33
00:01:48,360 --> 00:01:50,440
Speaker 1: to understand how much juice is left on that battery

34
00:01:50,440 --> 00:01:53,960
Speaker 1: because they decompose over time. And Jonathan and I both

35
00:01:54,000 --> 00:01:55,920
Speaker 1: knew of a way to do it, but it turns

36
00:01:55,960 --> 00:01:59,040
Speaker 1: out it's not exactly right. No. It for one thing,

37
00:01:59,040 --> 00:02:01,760
Speaker 1: it might actually harm your battery or at least decrease

38
00:02:01,800 --> 00:02:05,320
Speaker 1: it's useful lifespan. And we're talking lifespan. We're not necessarily

39
00:02:05,360 --> 00:02:07,760
Speaker 1: talking how long it will hold a charge. We're talking

40
00:02:07,760 --> 00:02:10,120
Speaker 1: about how many times you can recharge it before that

41
00:02:10,160 --> 00:02:12,560
Speaker 1: battery is just a big lump of you know, it's

42
00:02:12,600 --> 00:02:14,440
Speaker 1: just a paper weight and you you need to get

43
00:02:14,480 --> 00:02:16,560
Speaker 1: a new battery. That's what we're really talking about when

44
00:02:16,560 --> 00:02:20,880
Speaker 1: we're talking about lifespan here. Now. The the the tactic

45
00:02:21,000 --> 00:02:23,520
Speaker 1: that we thought originally was the best to use was

46
00:02:23,560 --> 00:02:28,160
Speaker 1: that you use your mobile devices until the battery essentially

47
00:02:28,480 --> 00:02:31,800
Speaker 1: drains down to zero before you connect it back and

48
00:02:31,840 --> 00:02:35,760
Speaker 1: recharge it all the way back up to rather than say,

49
00:02:35,919 --> 00:02:37,800
Speaker 1: using it and it just dropped to maybe, you know,

50
00:02:38,800 --> 00:02:40,760
Speaker 1: or six, and then you you know, charge it up

51
00:02:40,760 --> 00:02:42,320
Speaker 1: to eighty and then you let it go down to

52
00:02:42,400 --> 00:02:44,640
Speaker 1: forty and then you charge it back up to maybe

53
00:02:44,639 --> 00:02:48,119
Speaker 1: eighty again or whatever. We were thinking, well, that's that's

54
00:02:48,120 --> 00:02:50,160
Speaker 1: not a good idea because eventually your battery is going

55
00:02:50,240 --> 00:02:52,079
Speaker 1: to think that eight is the new one hundred, sort

56
00:02:52,120 --> 00:02:55,799
Speaker 1: of like pink is the new black. Yeah. Yeah, And honestly,

57
00:02:55,880 --> 00:02:58,280
Speaker 1: that's uh most of the time, that's how you're going

58
00:02:58,320 --> 00:03:01,560
Speaker 1: to use these things. But as your let's face it,

59
00:03:01,639 --> 00:03:04,000
Speaker 1: your cell phone, you don't want to go, uh, driving

60
00:03:04,000 --> 00:03:08,120
Speaker 1: around long distance, especially in a um car that may

61
00:03:08,200 --> 00:03:10,600
Speaker 1: or may not make it to the destination with a

62
00:03:10,639 --> 00:03:13,760
Speaker 1: half a bar left of battery life. You're gonna say, look,

63
00:03:13,800 --> 00:03:15,960
Speaker 1: I need my cell phone charge all the way. I

64
00:03:16,000 --> 00:03:18,240
Speaker 1: can't let it drain all the way and I you know,

65
00:03:18,400 --> 00:03:21,040
Speaker 1: gotta get it charged right now. So this is not

66
00:03:21,400 --> 00:03:23,120
Speaker 1: how most people do things. This is you know, they

67
00:03:23,160 --> 00:03:24,760
Speaker 1: just get as much energy as they can on it

68
00:03:24,800 --> 00:03:28,120
Speaker 1: and go back out. But that's another charging cycle, that's

69
00:03:28,120 --> 00:03:30,880
Speaker 1: your battery uses, so charging cycles. This is a good

70
00:03:30,919 --> 00:03:34,960
Speaker 1: time to address that that issue. Now. A charging cycle,

71
00:03:35,800 --> 00:03:39,640
Speaker 1: a full cycle is essentially one of that battery's capacity.

72
00:03:40,400 --> 00:03:42,920
Speaker 1: A charging cycle is when you have reached the point

73
00:03:42,960 --> 00:03:47,080
Speaker 1: where you have used of that battery's capacity and recharged

74
00:03:47,120 --> 00:03:49,760
Speaker 1: it to That doesn't have to be all at once,

75
00:03:50,040 --> 00:03:52,240
Speaker 1: So in other words, you don't have to have used

76
00:03:52,240 --> 00:03:54,520
Speaker 1: all one of your battery and recharged it all the

77
00:03:54,520 --> 00:03:57,520
Speaker 1: way up. Yes, that will, that will mean one full cycle.

78
00:03:57,560 --> 00:03:59,840
Speaker 1: But you could also do it, say the use of

79
00:03:59,840 --> 00:04:02,280
Speaker 1: your battery every day of the week and you recharge

80
00:04:02,320 --> 00:04:06,360
Speaker 1: it at the end of the day, so Monday through Friday,

81
00:04:06,840 --> 00:04:11,000
Speaker 1: that equals and that's a full cycle as well. It

82
00:04:11,040 --> 00:04:13,040
Speaker 1: doesn't matter if it's all at once or in bits

83
00:04:13,040 --> 00:04:17,000
Speaker 1: and pieces, and batteries have a limited number of charge cycles.

84
00:04:17,839 --> 00:04:20,400
Speaker 1: That's true. Um, every time you do this, it it's

85
00:04:20,440 --> 00:04:22,800
Speaker 1: just that a little bit more wear and tear on

86
00:04:22,839 --> 00:04:26,000
Speaker 1: the battery. And in general, um a lithium ion battery

87
00:04:26,160 --> 00:04:29,279
Speaker 1: has thousands of charge cycles. Sure, so you know your

88
00:04:29,360 --> 00:04:32,960
Speaker 1: laptop battery will last several years in general before you

89
00:04:33,000 --> 00:04:35,320
Speaker 1: have to worry about replacing it. Yeah, usually at least

90
00:04:35,320 --> 00:04:38,600
Speaker 1: three or four. And another issue that you have to

91
00:04:38,680 --> 00:04:42,520
Speaker 1: keep in mind is that it will last, but it

92
00:04:42,600 --> 00:04:44,680
Speaker 1: may not hold as much of a charge as it

93
00:04:44,760 --> 00:04:48,200
Speaker 1: used to. That it'll it'll begin to degrade in quality,

94
00:04:48,240 --> 00:04:52,400
Speaker 1: so you'll have maybe charge now the battery, the meter

95
00:04:52,400 --> 00:04:54,760
Speaker 1: is still gonna say because it's holding a percent of

96
00:04:54,760 --> 00:04:58,560
Speaker 1: the energy it's capable of holding, but that isn't equal

97
00:04:58,600 --> 00:05:00,440
Speaker 1: to the hundred percent you got when you bought it

98
00:05:00,520 --> 00:05:03,240
Speaker 1: in the store. And that's where the uh, that's where

99
00:05:03,240 --> 00:05:06,640
Speaker 1: the electronics onboard whatever device that you're powering with a

100
00:05:06,680 --> 00:05:10,120
Speaker 1: rechargeable battery come in. See, the battery is going through

101
00:05:10,160 --> 00:05:14,640
Speaker 1: a natural chemical process um and storing the energy, and

102
00:05:15,279 --> 00:05:18,080
Speaker 1: it basically at some point can't hold quite as much

103
00:05:18,120 --> 00:05:20,000
Speaker 1: as it used to. Is Jonathan was just saying, But

104
00:05:20,040 --> 00:05:23,000
Speaker 1: your computer doesn't know that. It still thinks it can hold,

105
00:05:23,440 --> 00:05:26,440
Speaker 1: you know, as much as it did two cycles ago. Well,

106
00:05:26,480 --> 00:05:29,680
Speaker 1: the thing is over time, your computer is gonna say, hey,

107
00:05:29,720 --> 00:05:32,240
Speaker 1: look you you've got this much time left and you

108
00:05:32,320 --> 00:05:36,400
Speaker 1: don't um. And that's why, after a while, your laptop

109
00:05:36,480 --> 00:05:39,120
Speaker 1: is gonna say, you're gonna unplug your laptop. In twenty

110
00:05:39,120 --> 00:05:41,000
Speaker 1: seconds later, it's going to give you an alert telling

111
00:05:41,040 --> 00:05:43,240
Speaker 1: you you gotta plug in your computer or it's gonna die.

112
00:05:43,560 --> 00:05:45,400
Speaker 1: And you're gonna go, wait a minute, Just a second

113
00:05:45,440 --> 00:05:49,479
Speaker 1: ago it said I had nothing exactly. And then that's

114
00:05:49,480 --> 00:05:52,479
Speaker 1: where conditioning or calibrating your battery comes in. You have

115
00:05:52,560 --> 00:05:55,640
Speaker 1: to get them if you will in sync with one another. Now,

116
00:05:55,880 --> 00:05:58,520
Speaker 1: the best advice we can give you is that whenever

117
00:05:58,600 --> 00:06:01,919
Speaker 1: you buy a new device with a new battery in

118
00:06:02,000 --> 00:06:05,960
Speaker 1: it is charge that battery all the way up as

119
00:06:05,960 --> 00:06:09,520
Speaker 1: soon as you get home. Don't don't start using it.

120
00:06:09,600 --> 00:06:11,160
Speaker 1: Like if you've got a new cell phone it's got

121
00:06:11,160 --> 00:06:13,320
Speaker 1: a little bit of a charge on it, don't start.

122
00:06:13,360 --> 00:06:15,960
Speaker 1: Don't give in to temptation like I have done on

123
00:06:16,000 --> 00:06:20,479
Speaker 1: many occasions, and start using that that device. Immediately, go

124
00:06:20,839 --> 00:06:23,120
Speaker 1: and charge it all the way up to This will

125
00:06:23,120 --> 00:06:26,200
Speaker 1: calibrate your battery. It will tell your device, hey, I'm

126
00:06:26,240 --> 00:06:28,200
Speaker 1: at a full charge. This is what a full charge

127
00:06:28,279 --> 00:06:31,159
Speaker 1: looks like. Um, this is what I should shoot for

128
00:06:31,279 --> 00:06:36,719
Speaker 1: every single time I am charging up to Otherwise, your

129
00:06:36,920 --> 00:06:40,920
Speaker 1: your device maybe reading your batteries life incorrectly, and as

130
00:06:41,000 --> 00:06:43,160
Speaker 1: Chris pointed out, it might tell you you have a

131
00:06:43,400 --> 00:06:45,880
Speaker 1: dred percent, but in reality you're closer to maybe seventy

132
00:06:45,960 --> 00:06:49,000
Speaker 1: or eight, and you're not getting as much out of

133
00:06:49,000 --> 00:06:53,200
Speaker 1: your mobile devices as you would otherwise. Yeah, and it's

134
00:06:53,360 --> 00:06:55,359
Speaker 1: it's hard, you know, here, we here again, this is

135
00:06:55,400 --> 00:06:57,120
Speaker 1: not how we use things. We're gonna want to get

136
00:06:57,160 --> 00:06:59,560
Speaker 1: into the temptation to go ahead and turn on your

137
00:06:59,560 --> 00:07:03,920
Speaker 1: new cell phone and start playing HTCG one, which I

138
00:07:03,960 --> 00:07:09,159
Speaker 1: did that with and immediately needed to recalibrate. Yeah, exactly. Um,

139
00:07:09,240 --> 00:07:11,200
Speaker 1: but yeah, all of us are excited about having the

140
00:07:11,240 --> 00:07:14,320
Speaker 1: new gadget and want to go ahead and start using it.

141
00:07:14,360 --> 00:07:17,280
Speaker 1: But you have to and and that's fine, it's gonna

142
00:07:17,280 --> 00:07:19,080
Speaker 1: be fine. But the thing is your battery is not

143
00:07:19,160 --> 00:07:21,480
Speaker 1: going to be fully calibrated and it's not going to

144
00:07:21,520 --> 00:07:23,640
Speaker 1: give you the maximum life out of the battery. And

145
00:07:24,080 --> 00:07:26,120
Speaker 1: you know, these things are expensive. If you've had to

146
00:07:26,120 --> 00:07:29,560
Speaker 1: replace a computer battery on your laptop, you go, you know,

147
00:07:29,600 --> 00:07:32,480
Speaker 1: a hundred and fifty dollars and five dollars. That's that's

148
00:07:32,520 --> 00:07:34,960
Speaker 1: pretty expensive. It's not you want to try to get

149
00:07:35,000 --> 00:07:36,640
Speaker 1: as much life as you can out of it. So

150
00:07:36,800 --> 00:07:39,360
Speaker 1: it's it's a good idea to do this, and you

151
00:07:39,360 --> 00:07:42,400
Speaker 1: need to do it every so often. Um, not every

152
00:07:42,400 --> 00:07:44,520
Speaker 1: week or anything like that, but I think the experience

153
00:07:44,760 --> 00:07:47,960
Speaker 1: experts recommend that it, you know, once every month or

154
00:07:47,960 --> 00:07:49,840
Speaker 1: a couple of months, you should go through it again. Now,

155
00:07:49,840 --> 00:07:52,320
Speaker 1: it does take a charging cycle to do that, but

156
00:07:52,560 --> 00:07:56,240
Speaker 1: it's worth it to to do that. Yeah, And here's

157
00:07:56,240 --> 00:07:58,480
Speaker 1: some other tips that you can use to help keep

158
00:07:58,520 --> 00:08:01,400
Speaker 1: your battery life lasting as long as possible. If you're

159
00:08:01,440 --> 00:08:04,320
Speaker 1: not using a device regularly, if it's just in a

160
00:08:04,400 --> 00:08:06,840
Speaker 1: once in a blue moon, it's a good idea to

161
00:08:06,840 --> 00:08:09,000
Speaker 1: to to take the device out every now and then

162
00:08:09,080 --> 00:08:11,680
Speaker 1: and let it run for a little while. Uh uh.

163
00:08:11,880 --> 00:08:15,960
Speaker 1: Apple actually calls this encouraging the flow of electrons. Uh

164
00:08:16,040 --> 00:08:20,000
Speaker 1: So if you have electron right exactly, you can do it.

165
00:08:20,440 --> 00:08:22,920
Speaker 1: And uh yeah, if you don't do that, then it's

166
00:08:23,360 --> 00:08:26,800
Speaker 1: the battery life can actually degrade over time. So even

167
00:08:26,880 --> 00:08:29,280
Speaker 1: if you're not using it often, it's good to take

168
00:08:29,320 --> 00:08:31,000
Speaker 1: it out once in a while, you know, like if

169
00:08:31,040 --> 00:08:34,080
Speaker 1: it's an old cell phone or any other device like

170
00:08:34,120 --> 00:08:36,600
Speaker 1: a gaming device. If you have a gaming device as

171
00:08:36,600 --> 00:08:39,839
Speaker 1: a rechargeable battery, um, you're gonna want to at least,

172
00:08:39,920 --> 00:08:41,520
Speaker 1: you know, let it run for a little well, you know,

173
00:08:41,600 --> 00:08:43,319
Speaker 1: let's let your little cousin who never gets to play

174
00:08:43,360 --> 00:08:46,240
Speaker 1: it give a world on legend of Zelda or something,

175
00:08:46,480 --> 00:08:49,880
Speaker 1: and that way it will uh with the electrons flowing,

176
00:08:50,000 --> 00:08:55,160
Speaker 1: it keeps everything uh more prepared for the whole charging

177
00:08:55,280 --> 00:09:00,440
Speaker 1: and draining cycle. Um. Also, when you store batteries storm

178
00:09:00,440 --> 00:09:03,760
Speaker 1: in a cool but not cold place, you don't want

179
00:09:03,760 --> 00:09:06,960
Speaker 1: it to get too hot, um because that will will

180
00:09:07,000 --> 00:09:10,520
Speaker 1: definitely shorten your batteries useful life. You don't want to

181
00:09:10,520 --> 00:09:13,640
Speaker 1: get too cold because that can also kill a battery. Also,

182
00:09:13,679 --> 00:09:16,280
Speaker 1: it takes longer for the battery to warm up and

183
00:09:16,320 --> 00:09:19,920
Speaker 1: actually you know, start providing juice to whatever device you have.

184
00:09:20,320 --> 00:09:23,840
Speaker 1: So you want a nice medium, something nice and cool. Um.

185
00:09:23,880 --> 00:09:26,640
Speaker 1: You know, you don't want to keep a whole bunch

186
00:09:26,640 --> 00:09:29,560
Speaker 1: of extra batteries on hand either, they will degrade on

187
00:09:29,640 --> 00:09:32,360
Speaker 1: their own, even if you don't have them attached to anything. Uh,

188
00:09:32,480 --> 00:09:35,880
Speaker 1: it's better to you know, you have maybe maybe an

189
00:09:35,880 --> 00:09:38,280
Speaker 1: extra one if it's a device where you know there's

190
00:09:38,280 --> 00:09:41,559
Speaker 1: a problem where it's just sucking down battery life so

191
00:09:41,640 --> 00:09:44,520
Speaker 1: fast that you needed an extra but I would, um,

192
00:09:44,559 --> 00:09:47,960
Speaker 1: I would recommend actually finding a like an extra charging

193
00:09:48,200 --> 00:09:51,079
Speaker 1: device for that, something that can hold a charge and

194
00:09:51,280 --> 00:09:55,120
Speaker 1: uh and and charge your device, usually through a USB cord.

195
00:09:55,280 --> 00:09:58,360
Speaker 1: I've got one of those, um where it will hold

196
00:09:58,840 --> 00:10:02,760
Speaker 1: probably about of my my g one's battery life on

197
00:10:02,760 --> 00:10:04,840
Speaker 1: this device. So if if I were to hit a

198
00:10:04,880 --> 00:10:07,160
Speaker 1: really low level, I could just plug it in and

199
00:10:07,320 --> 00:10:09,400
Speaker 1: keep it going for another couple of hours before I

200
00:10:09,400 --> 00:10:13,720
Speaker 1: needed to find a a more permanent solution. That's true.

201
00:10:13,760 --> 00:10:16,080
Speaker 1: And if you know, if you're to the point where

202
00:10:16,080 --> 00:10:19,080
Speaker 1: you're not using something that has a rechargeable battery in it,

203
00:10:19,160 --> 00:10:22,320
Speaker 1: and you realize you're probably not going to use it again,

204
00:10:22,360 --> 00:10:24,400
Speaker 1: it's probably best to go ahead and remove that battery

205
00:10:24,400 --> 00:10:27,839
Speaker 1: before it starts to corrode and you know, just to

206
00:10:27,880 --> 00:10:31,719
Speaker 1: recycle that sucker or you know, you know, recycled the

207
00:10:31,760 --> 00:10:34,280
Speaker 1: hold darn thing. If you have an old cell phone battery,

208
00:10:34,280 --> 00:10:37,560
Speaker 1: acid is no joke. It can ruin lots and lots

209
00:10:37,559 --> 00:10:45,560
Speaker 1: of cool stuff. Well details details, um So, essentially, there

210
00:10:45,559 --> 00:10:48,040
Speaker 1: are a lot of different theories on how you should

211
00:10:48,040 --> 00:10:51,240
Speaker 1: do this. Um, if you're going to calibrate your computer battery,

212
00:10:51,440 --> 00:10:53,840
Speaker 1: Apple has some suggestions from their website that I got.

213
00:10:54,240 --> 00:10:58,240
Speaker 1: Different manufacturers have different ways of doing that. But um,

214
00:10:58,400 --> 00:10:59,960
Speaker 1: the first thing you need to do, according to Apple,

215
00:11:00,080 --> 00:11:02,160
Speaker 1: is to plug your computer in and and let it

216
00:11:02,240 --> 00:11:04,240
Speaker 1: go until it's fully charged. Now you can actually run

217
00:11:04,280 --> 00:11:07,280
Speaker 1: your computer during this time. UM, but you're supposed to

218
00:11:07,360 --> 00:11:09,959
Speaker 1: let the battery rest for two hours. Don't unplug the

219
00:11:10,000 --> 00:11:14,760
Speaker 1: computer while you're using it. UM, that's really important. Um.

220
00:11:14,840 --> 00:11:17,640
Speaker 1: And then basically you need to unplug it and let

221
00:11:17,679 --> 00:11:19,760
Speaker 1: it run. You know, you can use it or just

222
00:11:19,840 --> 00:11:22,400
Speaker 1: let it sit until it goes to sleep on its own,

223
00:11:22,840 --> 00:11:26,120
Speaker 1: and then go ahead and plug it back in. Actually

224
00:11:26,200 --> 00:11:29,679
Speaker 1: wait a minute, sorry, check in my notes. This just in.

225
00:11:30,600 --> 00:11:31,920
Speaker 1: Once you do let it go to sleep, you need

226
00:11:31,960 --> 00:11:36,360
Speaker 1: to let it sit for about five hours. Wow. And uh.

227
00:11:36,480 --> 00:11:38,800
Speaker 1: And then once you do that, you can plug it

228
00:11:38,840 --> 00:11:40,320
Speaker 1: in until the battery is fully charged and you can

229
00:11:40,360 --> 00:11:43,160
Speaker 1: use it as normal. Uh. There's no mention of whether

230
00:11:43,240 --> 00:11:44,920
Speaker 1: or not you have to draw a circle on the

231
00:11:44,920 --> 00:11:49,640
Speaker 1: floor or sacrifice alive chicken. Uh. Yeah, it does seem See.

232
00:11:49,640 --> 00:11:51,160
Speaker 1: I had to write it down because I didn't have

233
00:11:51,160 --> 00:11:54,360
Speaker 1: it all memorized. UM. Some manufacturers, although Apple is not

234
00:11:54,400 --> 00:11:57,240
Speaker 1: one of them, actually have software that they include with

235
00:11:57,280 --> 00:12:00,960
Speaker 1: their laptops that help you calibrate your battery UM. A

236
00:12:01,000 --> 00:12:04,040
Speaker 1: lot of PC manufacturers will do that to help you

237
00:12:04,400 --> 00:12:06,800
Speaker 1: go through the steps and you don't have to read

238
00:12:06,840 --> 00:12:08,680
Speaker 1: a long list of things that you might get lost

239
00:12:08,720 --> 00:12:10,800
Speaker 1: in the middle of like I did right and well

240
00:12:10,840 --> 00:12:13,520
Speaker 1: and and the encouraging the flow of electrons. Part of

241
00:12:13,559 --> 00:12:17,280
Speaker 1: that also is if you use your your laptop and

242
00:12:17,320 --> 00:12:20,640
Speaker 1: you plug it in a lot like like we do here,

243
00:12:21,120 --> 00:12:23,120
Speaker 1: it's a good idea every now and then to just

244
00:12:23,200 --> 00:12:25,400
Speaker 1: let run on battery life and and use it on

245
00:12:25,440 --> 00:12:27,120
Speaker 1: battery life for a while, and then you know, you

246
00:12:27,120 --> 00:12:29,240
Speaker 1: plug it back in and you know that's fine. You

247
00:12:29,240 --> 00:12:31,240
Speaker 1: can work on it, but but vary it so that

248
00:12:31,400 --> 00:12:33,840
Speaker 1: sometimes you're using it on battery, sometimes you're using it

249
00:12:34,400 --> 00:12:38,120
Speaker 1: under you know, a cable power and UM and that

250
00:12:38,160 --> 00:12:42,000
Speaker 1: can also help extend your batteries life and all of them.

251
00:12:42,120 --> 00:12:44,520
Speaker 1: You know, again, you don't have to do this, it's

252
00:12:44,600 --> 00:12:46,600
Speaker 1: not something that's required, but it is going to help

253
00:12:46,600 --> 00:12:48,640
Speaker 1: you get the maximum life out of the battery, which

254
00:12:48,679 --> 00:12:52,280
Speaker 1: is a sizeable investment if you have to go have

255
00:12:52,280 --> 00:12:54,680
Speaker 1: have it replaced especially if it's something that you have

256
00:12:54,760 --> 00:12:57,640
Speaker 1: to have somebody else replaced for you, and in different

257
00:12:57,640 --> 00:13:01,400
Speaker 1: electronics that have to be eervis by the manufacturer. So

258
00:13:01,800 --> 00:13:04,240
Speaker 1: I can think of one manufacturer right off the top

259
00:13:04,240 --> 00:13:08,160
Speaker 1: of my head where that as a common problem. Yes,

260
00:13:08,520 --> 00:13:11,240
Speaker 1: my wife, this is a good segue into that my

261
00:13:11,280 --> 00:13:15,040
Speaker 1: wife had battery replaced. My wife has a popular MP

262
00:13:15,160 --> 00:13:19,560
Speaker 1: three brand player. Um that what she couldn't have. She

263
00:13:19,600 --> 00:13:21,520
Speaker 1: it wouldn't hold a charge, it would, you know, She

264
00:13:21,640 --> 00:13:23,520
Speaker 1: try and turn it on and it would stay on

265
00:13:23,640 --> 00:13:25,960
Speaker 1: for a couple of seconds, it wouldn't necessarily play a

266
00:13:25,960 --> 00:13:27,880
Speaker 1: song or would start playing. It would immediately just go

267
00:13:27,920 --> 00:13:29,679
Speaker 1: black and she wouldn't be able to do anything with it.

268
00:13:30,280 --> 00:13:33,120
Speaker 1: And it turned out it was this problem where the

269
00:13:33,320 --> 00:13:36,160
Speaker 1: software was not recognizing how much power was left in

270
00:13:36,200 --> 00:13:39,800
Speaker 1: the battery, and all it really took was resetting the

271
00:13:39,800 --> 00:13:43,960
Speaker 1: the device back to its original settings, charging it all

272
00:13:44,000 --> 00:13:46,880
Speaker 1: the way up and everything's fine now. Unfortunately, in the

273
00:13:46,920 --> 00:13:50,040
Speaker 1: process that means losing all the stuff that was on there,

274
00:13:50,080 --> 00:13:53,160
Speaker 1: so we had to reload it. But that's still even

275
00:13:53,200 --> 00:13:55,920
Speaker 1: though that's annoying and frustrating, that's not nearly as annoying

276
00:13:55,920 --> 00:13:58,800
Speaker 1: and frustrating as buying a new device when you think

277
00:13:58,800 --> 00:14:01,320
Speaker 1: that you've broken your old one. The old one wasn't broken,

278
00:14:01,360 --> 00:14:05,640
Speaker 1: it just needed to be recalibrated. Yeah, and it's certainly

279
00:14:05,679 --> 00:14:09,160
Speaker 1: an inexpensive thing to try. I mean, recalibrating the battery

280
00:14:09,200 --> 00:14:11,719
Speaker 1: doesn't cost you anything except maybe a battery cycle. So

281
00:14:12,400 --> 00:14:14,040
Speaker 1: you know it might be worth it to try. And

282
00:14:14,080 --> 00:14:17,000
Speaker 1: next time you have something some weird behavior go on,

283
00:14:17,280 --> 00:14:20,240
Speaker 1: at least before you go and drop three more dollars

284
00:14:20,240 --> 00:14:24,720
Speaker 1: on a new something. Very true, Very true. That was

285
00:14:24,760 --> 00:14:26,400
Speaker 1: a good discussion, I think. Are you you know? I

286
00:14:26,640 --> 00:14:29,320
Speaker 1: got a real charge out of it. Oh geez, hopefully

287
00:14:29,320 --> 00:14:33,640
Speaker 1: our listeners did too. I find it revolting nice. Well,

288
00:14:33,680 --> 00:14:37,320
Speaker 1: before we go with this shocking podcast, I would like

289
00:14:37,440 --> 00:14:41,280
Speaker 1: to once again visit our favorite segment, Plug your Ears Pillette.

290
00:14:41,720 --> 00:14:48,040
Speaker 1: It's listener mail. Can I plug my ears? And So?

291
00:14:48,160 --> 00:14:53,560
Speaker 1: Today's listener mail comes from Chris Besquez of St. Thomas, Ontario, Canada.

292
00:14:53,960 --> 00:14:58,320
Speaker 1: So hello a and for Chris writes. He says, Hey

293
00:14:58,360 --> 00:15:00,760
Speaker 1: guys from Tech Stuff that be Us. You have a

294
00:15:00,760 --> 00:15:04,120
Speaker 1: great podcast, Thanks Chris, but you have did have an error.

295
00:15:04,160 --> 00:15:05,880
Speaker 1: In one of your latest podcasts, you said that you

296
00:15:05,920 --> 00:15:07,880
Speaker 1: would never see a virus in your task bar. But

297
00:15:07,960 --> 00:15:10,440
Speaker 1: that's not true. You see plenty of viruses in your

298
00:15:10,480 --> 00:15:13,600
Speaker 1: task bar if they're designed to be there. There's tons

299
00:15:13,600 --> 00:15:16,080
Speaker 1: of viruses that say you have a virus on your computer,

300
00:15:16,360 --> 00:15:20,400
Speaker 1: so you install their anti virus software, which is actually

301
00:15:20,520 --> 00:15:24,000
Speaker 1: a virus. There are other ones as well. Now, Chris,

302
00:15:24,040 --> 00:15:26,320
Speaker 1: I see what you're saying here. Um, I agree. There

303
00:15:26,320 --> 00:15:29,240
Speaker 1: are programs out there that are a viruses out there

304
00:15:29,320 --> 00:15:32,680
Speaker 1: that are masquerading as legitimate programs. They try and trick

305
00:15:32,760 --> 00:15:36,440
Speaker 1: you into downloading a virus by saying, hey, your computer

306
00:15:36,520 --> 00:15:39,000
Speaker 1: is at risk. You need our software so that you

307
00:15:39,040 --> 00:15:42,960
Speaker 1: won't be attacked by viruses. And many of us think, hey,

308
00:15:43,000 --> 00:15:44,480
Speaker 1: that's a good idea because I don't want to get

309
00:15:44,480 --> 00:15:46,880
Speaker 1: attacked by virus. So you download it, not knowing that

310
00:15:46,920 --> 00:15:50,160
Speaker 1: you're actually installing a virus on your own computer. And

311
00:15:50,200 --> 00:15:52,440
Speaker 1: you might see that in the system trade and and

312
00:15:52,520 --> 00:15:55,120
Speaker 1: you would go, hey, look my virus protection software. There

313
00:15:55,120 --> 00:15:57,840
Speaker 1: it is, it's workings running. Now, what we were saying

314
00:15:58,000 --> 00:16:01,720
Speaker 1: is you would not see a blately obvious virus in

315
00:16:01,760 --> 00:16:04,160
Speaker 1: your task bar because that would give away the whole,

316
00:16:05,000 --> 00:16:07,400
Speaker 1: the whole uh point that there was a virus on

317
00:16:07,440 --> 00:16:10,200
Speaker 1: your computer. Um, so that was that was the point

318
00:16:10,280 --> 00:16:13,240
Speaker 1: we were making, Chris, was that we don't think you

319
00:16:13,240 --> 00:16:15,600
Speaker 1: would see a little skull and crossbones in your task

320
00:16:15,600 --> 00:16:18,240
Speaker 1: bar saying ha ha, I got you you have a virus,

321
00:16:18,280 --> 00:16:20,200
Speaker 1: because that would mean that you would take the steps

322
00:16:20,240 --> 00:16:23,040
Speaker 1: necessary to remove it. But you are right. If you

323
00:16:23,160 --> 00:16:26,680
Speaker 1: install a virus that is masquerading as a legitimate program,

324
00:16:26,720 --> 00:16:28,520
Speaker 1: it could show up in your task bar. So thank
