C3 Battery Charge Cycling

Just recently my one month old C3 has been having charging issues.
When plugged into the wall charger, the phone will report that the battery is full and that it can be unplugged to save energy. It shows a full charge on the battery indicator, but after being unplugged for a minute, the low battery indicator alarm sounds.
I've been monitoring the phone at work this morning and found the following:
When it is plugged into the wall, the phone will report that it is fully charged, but will beep that it is charging every 3 minutes. And then, it will only charge for 20 seconds.
The battery charge indicator animation seems to be very fast as well.
It's been doing this for the last 45 minutes.

hello c3 users,
i ve got a solution, lets c if it works... Ur mobiles r have no problem, so dont worry!!
Just pull out the battery of ur mob, and tight all the jaws of the BATTERY from both sides through which battery holds the mobile plugs... But becarefull these r very sensitive!!!!!!
Tight these jaws through needle coz these r very small,
the problem u guys r telling happens when one of them becomes lose it causes the breakage of the circuit between the battery and mobile and when it happens the mobile sends the low battery signal, mob doesnt turnoff because not all of the circuts r broken, the problem might be in one of them,
so try it and lemme know if it solves ur problem!!

My iPod dies!!! after the first battery charge cycle

Hi,
Last month I bought a 30GB iPod video through Amazon when I was on vacations on the US, now I'm in my hometown Lima (Peru)... well, for the month I had the iPod, everything worked fine, but I've never let the battery died, I mean I've always have it fully charged and never get the "not enougth battery message".. until yesterday when it suddenly stops playing.
Well I tough it was nothing so I turn the iPod on again and there was the Apple logo (it was the second time I saw it, the first was on the firmware update), then I get the not enough battery sign, I tougth it was ok.... then I get home, connect to the USB port I always use to synchronize it, and NOTHING happens!!!, the computer does not reconigze it, and it doesn't turn on either, there's nothing on the screen, but I did have noticed something: the iPod was hot, I immediately disconnect it from the USB (it was plugged for about 10 seconds), I've tried to reset it (procedure I've just learned since I've never had any problems with the iPod)... and no matter what i did, it didn't turn on.
I don't think the problem is the USB port because I try to connect a USB drive, and it works.
The questions is...what can I do to fix it?, I'm sure my iPod is covered by the "Apple One-Year Limited Warranty" but the problem is that I'm in Lima!! do I have to send the iPod to the US?? pleeease help me!! I save a year to be able to buy an iPod and now it isn't working!!
Thanks in advance.
AMD Athlon XP 2400+ Windows XP Pro

Thank u, Ryan, Masna and Kpxjoon...and of course I've tried the 5 R's... I think I've read every single post to find if anyone had a similar problem.. anyway
So.. Broken? how? ... well that's what I thought in first place, that I would have to send the it for service, the biggest problem is that I'm not in the US now, I bought the iPod on the US through Amazon (the shipping address was on the US too)... well now in Lima (Peru), I live here and I wouldn't return to the US anytime soon, Does the warranty still work in here??
I went to iPod Service Request site... and bad news for me again "If you cannot find the country you are looking for.... If you live outside these countries, please contact your local Apple Authorized Service Provider."
I found some Authorized Service Centers in Lima, do I have to take the iPod to them and they will fix or replace it with no charge, even though I purchase the iPod on the US??... it was my biggest worry since the beginning...
The iPod and it's package is in perfect shape, it evens has the plastic wrap, which it comes with...and I keep it in a case, so there's almost no scratches on it, and it's just a MONTH old!!!...I'm not worry about the data, 'cause everything is on my iTunes Library... I just want my iPod back
Sorry for posting so often, Thank u very much for ur time

My Macbook Air 11 (late 2010) not charging "battery replace now) message 28 months old only 6 charge cycles. what could cause this?

I've unplugged plugged in. Checked the charger. Nothing runing. I've Shut down rebooted ran diagnostics and just about everything resolution I could find on-line. Its almost always plugged in and has not been used on battery power in a long time. Its not run down to zero power before. Just suddenly shut off the other day and won't charge now. Says replace battery now, but I just want to see if it could be something else. Hard to believe the battery went bad like that.
Thanks

always plugged in and usually in sleep mode.
So it was always plugged in, never discharged, and was never really OFF, just in sleep mode.
Sounds like you got some half-true 'advice' from some people.
It DOES shut down when fully charged and you cant "overcharge" your macbook....., and the "others" were correct that your battery should be cycled every couple weeks at least.
what they didnt tell you is "plugged in and OFF is one thing.......plugged in ALL THE TIME...AND in sleep mode (for years)......NO!"
Heres some info for the "next battery" :
Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
*Contrary to some myths out there, there is protection circuitry in your macbook and therefore you cannot 'overcharge' it when plugged in and already fully charged
If you leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.
LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...
LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.
**Also new evidence suggests that sudden loss of power can adversely affect data on a SSD (solid state drive).....again, dont let it ever shut down from total power loss
The only quantified abuse seen to LiPo cells is instances when often the cells are repeatedly drained very low.
Contrary to what some might say, LIPo batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity.
Same way you dont take a new car out and speed and rev the engine hard first 100 or so miles.
*Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
Just use and enjoy your new macbook,
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
and best "tip" is if its near a socket, .....plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"

Maximum battery life obtained on an iPhone for one charge cycle?

Hi all,
I wanted to know what is the maximum battery life anyone obtained on an iPhone for one charge cycle? What is the average? I managed to get 4 hours of access time (Phone and Internet) and 2 days standby and wanted to know what the average is.

I tried to limit my phone usage to only calls and occasional mail check (I pop mails once an hour), and the best I could get till now for that has been 4 hours and 40 minutes. Took care to reduce the brightness to 70% and always lock the phone (by pressing the Sleep/Wake button), removed keyboard clicks and disabled wireless network availibility. Is 4 hours talk time + internet alkong with maybe 2 days standby a decent figure to expect for the iPhone performance?

My battery is at 516 charge cycles, charge capacity of 4129. Is it defective?

My Macbook is a late 2009 white 13" unibody model, and I understand that it should withstand up to 1000 charge cycles. I am only at 516 charge cycles, yet my battery life is dwindling, lasting approximately half as long as it did when new. I've seen it drop from lasting for five or six hours with normal use to two or three hours with normal use just in the past few months. System profiler says its full capacity is 4129 mAh; this is after I reset the SMC and calibrated the battery in an attempt to fix my problem. It charges to the indicated capacity but as I said, lasts nowhere near as long as one would expect. I remember its capacity being around 5100 when I first purchased my Macbook in April of 2010.
Obviously the laptop is out of warranty - not like it matters, since batteries aren't covered. What I was wondering is if this battery would be considered defective considering it has only lasted half as long as it "should" according to Apple's standards.

My charge cycles reflect daily use, and I can't imagine how it is excessive. I guess it might be, but I use it as I think a laptop is intended to be used. I don't leave it plugged in all day; I make use of its portablility and run it on battery at least half of the time. I usually plug it in before the battery reaches 20% as recommended by Apple, but it has on a few occasions been completely drained. I don't think my use is extraordinary.
Since posting this my laptop has fully recharged after the calibration, and its status has changed. It used to say that my battery condition was "service needed" (which is what prompted me to look at how it's been performing) but now the stats read as follows. Even the capacity changed, which is interesting. I guess recalibrating the battery removed the service warning, so I'll see how long it lasts off the battery alone over the next few days.

First battery charge and current issues?

Hi!
I just bought a new MacBook (2.0 GHz, 160 GB). I have two quick questions:
1. I plugged in my AC adapter, turned on the notebook for about 5 minutes to make sure it works fine, etc, then shut it down to let the battery charge. Would I have lost any battery capacity by not fully charging the battery first? And do I need to let the battery run through a full cycle when I first use the computer to ensure full capacity?
2. Are there any updates/best practices for the 2008 (December) MacBook batteries? I know there was an issue in 2007, but for the new line am I set to go? And is it still best practice to put shut the Mac down instead of putting it to sleep to save wear and tear on the hard-drive/battery?
sorry for all the questions: it has been 5 years since I bought my last notebook so I am a bit rusty/excited!

Weird battery charging behaviour

Ok, I'll start by saying that this is a problem that has been coming and going for quite a while (definitely months, maybe years). But for the sake of illustration, I'll describe what happened today.
So last night I was using my laptop on the couch (not plugged in) and fell asleep. Woke up to a dead battery. No problem, I plugged it in and woke it up and was good to go. Several hours later I noticed that my battery charge was still at 1 or 2%, though clearly it was running just fine off AC power. Looking at the light on the power adapter, I thought it was completely off until I read a few support posts and found out that "dim green" is an option. Upon close examination, yep, dim green. System Information said the battery itself was ok (cycle count 153, condition normal) but not charging. Under AC Charger Information, it said Connected: yes, Charging: no.
Unplugging and replugging the adapter a few times didn't seem to do anything. There's no obvious gunk in around the terminals. I shut down and reset SMC, no change. Finally I just fiddled with the adaptor (unplug, replug, flip around, wiggle up and down) until the light turned briefly green, and then orange. Now it's clearly charging (up to 38% now, and battery icon has a little lightning bolt) although System Info still says it isn't charging.
Oh, hang on. I just quit and restarted System Info, and now it says it is charging! Huh.
Addendum: While adding tags I noticed that the light on the adapter is back to dim green. System info still says it's charging, and battery % charged numbers are still going up.
I'm guessing it's an issue with the magsafe adaptor, just not sure how you end up with a temporary situation where the laptop can run on AC power but can't charge the battery.
Oh, and in case it's relevant: I'm running a 13" mid-to-late 2009 MacBook Pro, the kind with a non-removable battery, though I did have the battery replaced (by a friend who is Apple-certified) less than a year ago. The AC adaptor I'm using is the one that came with the computer. I'm pretty sure the problem pre-dates the new battery (since it comes and goes, and because I spend a lot of time using the laptop at home while plugged in, I don't always notice).

I had this exact same problem with my mid-2009 MBP as well. My adapter (white connector) has suddenly stopped charging the computer and displayed a very dim-green LED instead of the normal orange or bright green.
I came to the conclusion that the adapter has been shorted out in some way (possibly due to old age) and that was the cause of this. Sure enough my local Apple retailer sold me a new adapter that everything has been fine ever since. I even enjoy the new design - the metal-tipped connector that faces sideways.
Unfortunately the adapter cost me $80, but was a small price to pay as opposed to replacing my laptop. Since this sounds like the exact same issue I faced, I would recommend you purchase a new MagSafe. Just make sure you get the right one for your model (should be a 60W MagSafe)
Hope this helps you out!

Battery charging: When do you do it?

Hey guys,
I've done searches on the forums and can't find the answer i desire. I know that the lithium batteries have charge cycles, and at least once a month you should fully drain, and fully charge the phone. And that there is no memory in the battery, so a partial charge shouldn't mess anything up (except the battery indicator)
But my question is, When do you charge it to make the battery last the longest. Not time between charges, but over all battery life. Everyone always complains you can't replace the battery yourself, and it is quite annoying to send your phone in for a replacement battery (oh hey, no phone for a month. great)
But what can we as end users do to have our batteries live a long life (and hopefully not lose it's charge capacity?
(also, i read that some applications don't shut down properly when you hit the home button. And to shut them down 100% you need to hold the button down for 8 seconds? is this true? where can i find more documentation on this? And is there anyway to "See" what apps are running? That would be a nice thing.)
cheers,
Chris

Good point.
Problem is you don't have any control over the issue.
L-ion batteries typically have a recharge cycle of 500 times. Some confusion arises over what exactly a charge cycle is, is it full charge or incremental charges, so if I top-up say ten times, is that equal to one full charge? Experts will debate that one back and forth.
You plug in the USB cable and it starts charging, rather messes up your planned charging cycles, doesn't it?
Apple will need to redesign this phone to take extra capacity user replaceable batteries with a bulkier back panel ~ it has to become an option or even a neat lead to a belt battery, all features in use and the iPhone will last not much more than 2 hours, that's probably 4 full recharges in a day, that gives you 100 days, or a new battery every 3 months.
Obviously mileages vary ~ but at the rate I am using my iPhone, that's what my figures are panning out like.
My previous smart phone was charged each evening [mostly] expected life span one year and three months, it's still perfect after two years [but they do die quite quickly when they go].
Do please not here too, I could not play with my other phone the way I can with the iPhone ~ if I just used it as a phone, a charge a day would probably do too.
Most experts say that the L-ion battery has a total life span of no more than 3 years ~ from manufacture [not from sale of same]/

What is the max charge cycle?

What is the max charge cycle?
If it reach the max, will apple replace it under warrenty? or it not covered, and I have to buy new battery?
Like when you go to System Pref > About this mac > Power > Recharge Cycle.
It will tell you the amount of charged you made. What is the max you can recharge?

A properly maintained Apple notebook battery is designed to retain up to 80% of its original capacity after 300 full charge and discharge cycles. See http://www.apple.com/batteries for lots of good info on Apple batteries.

How does battery charge work ThinkPad T430s

I recently bought a Lenovo ThinkPad T430s 2356-LRG and was wondering how the charge technology worked. I have searched around and looked in the manual but I couldn't find a good answer.
My questions is that I use the notebook alot on AC power. And often for extended periods of mid to heavy load. I run Linux and have setup ChargeThreshold. It stops charge at 95% and begins again at 45%.
But when I keep the AC power on, and if the battery has 80% it does not move up or down as expected. Because it must drop lower than 45%.
Will the power then go straight to the machine and bypass the battery? Because the Battery-LED on the back is turned off. Or will it go via the battery and produce charge cycles on the battery?
So let's say the battery is bypassed will it then be fine to keep it on AC and active for a period of many days with heavy load but monitor the temp of the battery. I know heat kills it.
I could also buy an 95W power adapter and remove the battery completely from the machine when I have it at my desk for an extended period of time.
Solved!

Hey there MikalD and welcome to the forums!
What you are experiencing is as per normal. These charge thresholds are determined in your power manager, there is a nifty Knowledgebase Article about this.
First, open up the ThinkVantage Power Manager. Click on the battery tab, and then Battery Maintenance. This will open a window where you will be able to change and set your charging thresholds to your desired preferences.
Additionally, here are links that can give some insight and advice of how to increase the longevity of battery life.

Can someone explain this chart about Li-ion charge cycles to me

I consider myself a pretty smart guy, but i couldn't figure this out. I'm thinking that apple just provided this graph without any real explanation of what it means. I'm talking about the one on .. http://www.apple.com/batteries/ that has a caption starting with "Charge Cycle." They provide a general explanation of cycles below, but don't seem to address the same thing the illustration they provided does. What does the 40% 20% 30% 20% 50% 60% mean? Why is "1 Cycle" in the middle and what is the difference between cycle 0-1 and 1-2. basically that illustration makes no sense to me and i'd love for someone to explain it

That charge is telling you how the charger charges the battery. The voltage charge is the green line and the amperage is the orange line. Voltage goes up to its full extent in the first couple of hours. The amperage starts at full charge strength and goes down as the batery charges so it will not overheat the battery. The most important thing to know about charging a Li (Lithium-ion) battery is that it has two different charge times, quick and full. most Li batteries get about an 80% charge at the quick charge time and 100% charge at the full charge time. when you first charge any rechargable battery make sure you do a full charge and then a full discharge with another full charge afterward. If you do not do this the life of the batery will be significantly diminished.
I hope this information helps. If you want more information in this subject ask a more direct question.

Any way to stop battery charging at under 100%?

Research has shown that a battery kept at 40% charge will retain 96% of capacity after 1 year (at 25 degrees C), while a battery kept at 100% charge will retain only 80% of capacity after the same period of time.
Is there any way to control the maximum charge level, so that the battery stops charging after a certain point (say, 40%, or 75%). Thanks.

Do you have a link for the article you read that has this info? I'd love to read it!
Like the above poster said, you can't control how long the battery charges--unless you unplug the cord yourself.
I would like to mention something for you. My battery is 11 months old, and has maintained 98% of its original capacity. Within the next 4 weeks, it will hit the one-year mark, and I don't anticipate it failing on me before it has reached the typical lifespan of ~300 charge cycles. I wouldn't be surprised if it hangs on for another 100! It currently has 264 to its credit. I think my battery is doing pretty well--and I run off it for a few hours nearly ever day
Of course that's an expected outcome with most lithium rechargeable batteries. However - they do have their drawbacks including an inherent loss of total capacity from the aging process.
The best thing for your battery is to USE it, even if you're sitting at your desk much of the time. Unhook the power charger for 30 minutes, or an hour, then reattach it. If it doesn't seem to be working properly, calibrate it.
It all depends. Using a battery and charging it to near maximum by definition cut capacity because of some loss of the electrolyte solvent when it gets vented. In NiMH batteries, the solvent is water. It's a non-water solvent for lithium rechargeables. If it's not vented, it could potentially explode. Using a battery every day will result in noticeable loss of capacity. There's a balance to overuse and underuse of a lithium rechargeable battery. Apple recommends that a battery be partially drained at least once a month. My MacBook is set up with an iCal reminder to use battery power once a month.
The 40% you mentioned from the article is something I've heard before, but I believe it was mentioned in relation to storing your computer for an extended period of time(ie several weeks). If you wanted your battery to be healthy when you returned, you wanted to store it after you'd partially discharged the battery.
I've brought up the extreme case of first generation hybrid car batteries. They employ a different strategy for charging that takes advantage of an always present charging source (the internal combustion engine and generator). They take advantage of the extreme case where the battery is intentionally kept between 40-65% of charge nearly all of the time. Going a little bit under or over this isn't a big deal. This keeps it from the extremes of near max charge and near min charge; both tend to reduce battery capacity for different reasons. The electrical output is only a supplementary power source used during peak demand periods. I've heard of some original batteries from Toyota Prius taxis that have survived 400K miles of service; that probably meant 100,000-200,000 of the shallow charge-discharge cycles. The fact that only a small range is needed means that they can continue this use for a long time. It probably would have been noticeably degraded after maybe 1000-2000 20-100% deep discharge cycles. The total amount of energy drawn over the lifespan is many times with the small discharges compared to deep discharges. You're typically using 25% of the charge hundreds of thousands of times rather than 80% of the charge a few thousand times.

MacBook Air 2014 came with 12 charge cycles

I just got a brand new 13" MacBook Air from an authorized apple reseller, I went to check the battery cycles and there are already 12 on it even though I have only plugged it in once. Does anybody have an explanation for this? thanks

For what it's worth (and I don't mean to concern you at all as it is most likely very normal), I just checked the cycles on a Brand New Macbook Pro 13-inch (Mid 2012) and it has completed 0 charge cycles. I broke the seal myself and checked immediately without use.
You got me curious - thought it would be good to know

How does Mac OS calculate the charging Cycle count?

Hello, Guys
How does Mac OS calculate the charging Cycle count? I just used my MBP for about 15 min without power plugged in and I saw it left about 90% battery. However after the battery be recharged, I checked system profiler. It shows charging cycle count increased 1. I do remember that last time I left almost the same percentage of battery and plugged in. After the battery was fully charged, profiler did show cycle count increased.
So I am wondering How does Mac OS calculate the charging Cycle count? Basing on the percentage left or something else?
Thanks,

Ok,
But does it count continuously or separatly? I mean One time I used 10% and recharged full; and next time I used 20% and fully recharged again. Does the OS increase the cycle count when the usage adds up to 100% no matter how many times of recharge?
Thanks,

My info for battery charging says "Not Charging" when it is charging as per dashboard widget.

My info for battery charging says "Not Charging" when it is charging as per dashboard widget. Since change to lion all slowed down do I need more ram ( have 2 gig). Lost some icons in web site icons and other random icons. So far SL better.

Yeah, it was purchased in August 2008. I'm not really sure what a charge cycle is, but I do plug it in and unplug it a lot to a power source. Mainly because I keep my computer on most of the time (either on or on sleep). So between taking it to classes and stuff, I'll recharge in between and when it's really low, otherwise I run it off the battery most of the time.
On a sidenote, I have went to that information thing about about the battery after letting it sit plug in for a few hours, and now it has this information:
