Battery jumps after reboot while charging

Today it happened again, my battery is around 30%, I let it charge, I decide to turn the phone off and on again. When I turn it on, it suddenly shows it's 68% charged. Again I feel, I have lost the ability to fully load my battery since it now thinks it's full while it should be full an hour of charging later.
Can anyone tell what the hell is going on?
This happened to me before, see: http://forum.xda-developers.com/showthread.php?t=1074093

its happen to me too..
battery around 10% and after reboot while charging its become 40%
weird...
cm7.02+netarchy 1.3.1 cfs

Good to hear there are more people with this issue (don't take it personal).
This is a serious issue, I feel my battery life i becoming shorter and shorter.

Come on, anyone?

And it happened again, from 7% to 36 %. A real bug here.. why does nobody take this serious...

same here... hope there is a fix for this

If your phone is rooted, you can try to re-calibrate the battery by:
Charge the phone normally until it says Charged on the lock screen (you can turn on wi-fi in order to get more "fully" charge)
Turn off the phone, it will continue charging. Wait until the battery icon does not animate anymore (press Power button once to see the charging progress)
Turn on the phone, use adb shell or Root Explorer (or File Expert) and navigate to /data/system/
Delete the file named batterystats.bin
Reboot the phone

You can wipe battery stats in recovery, under the advance menu.

I've owned 3 Android devices and all 3 exhibited this behavior from Cupcake up to Gingerbread. Just ignore it because soon as you think it's stable it will revert back to doing it again. Just something I've learned to live with at this point.

If you're saying this is *really* serious then rooting is no big deal I guess

When my battery jumps I just keep using the phone until it dies and then recharge it. Crazy thing is, when it jumped from 12% to like 30%, my phone operated for a few hours while I texted and gamed on it so I don't really care that much. I have also yet to see any signs of deterioration.

Just one question, that puzzles me; why you don't want to root you phone?! Rooting is no biggie. And given the fact that this is a big prob for you, I suggest that you give it a try.

Battery life questions

So even with no widgets, a black background, mobile data and wifi off, and sync off my battery dies so fast that ill go to sleep at full charge and its dead when I wake up. And no I don't use it in my sleep. I'm running gummycharged 2.0 if that makes a difference. Any ideas or thoughts? Its a certified pre owned phone so maybe its just a shot battery ?

I have a similar situation. Mine drains like that at work but not at home. No amount of battery calibration, different ROMs, different SIM cards killing tasks, switching phones or anything else makes a difference. They all do the same thing. In my case, I believe it is the constant fluctuation of the actual Cell signal (not data signal) that is causing this. To see if this might be the case for you, let the phone run for a few hours where this is happening but don't let the phone die. Then go in to the "Battery Use" then select "Cell standby". If you see any percentage >0 in the "Time without signal" statistic, this may be what is causing it.

Time without signal 30%. I think you may be on to something. you might have just saved me buying a new battery, thanks friend

What do you mean by background data and how do you set that?

Just an observation, but the graph at the top under where it says 1 day 19 hours clearly shows your battery going up 3 times. Which I was just going to pass up but I have a bunch of shots of my battery stats and none of them go up.

So if I'm not mistaken you plugged in a couple times.

I seen that as well but I honestly have no idea why. I can assure you it has not been plugged in. I even have a prior screen shot on another battery run that has the same issue.

Thats impossible, theirs no way for a phone to charge itself while discharging. Something is screwed up with your battery calibration.

Battery Management
Hi, all.
I want to pass this tip along to anyone who want or need to conserve their battery for what ever reasons.
I have gone usually 3 day+ on one charge.
I'm running on stock rom. Froyo 2.2.1
It is rooted though
I use the phone moderately. Text occasionally.
I downloaded an app called "DataSwitch" by TomatoX.
I use wifi when I'm at home or work.
I have dataswitch activated when I don't need constant background data. ?I turn it on when I need to use it for surfing and such.
In Settings, there is also a toggle for background on/off, although I don't use this much.
With the data off, you can still get phone call and text msg.
I usually turn off data and wifi at bedtime.
On the third day, I'm usually down to 35%.
This may also be useful if you are low and can't get to a charge right away.
It may not apply to everybody, but it works for me..esp with only a 200mb data plan. Battery life is great!

lol look at that cell standby use your phone lol

Good one. But next time on, it would be more useful if you post the screenshots showing call duration and display time. With just this one screenshot it could have display on for just 5 mins or 50 mins. Its hard to tell.
Just now noticed, the tiny green bars in the screenshot (circled in red) come up when the phone is charging.

I noticed that (at least for my phone) if you connect it to wall charging it would reset the "time on battery" count but if i connected it via usb to pc it was charging, yeah slowly maybe but the timer never reset when connected via usb as if the phone said "well im charging but it doesnt counts since the guy its transfering data"(lmao yeah my phone is smart) so if you wait for 10% battery ans then go usb mode and charge it and use it and repeat i once got displaying 4 days 10 hours on battery haha.
While on my real stats my phone never last more than 18 hours ;/

I got my phone to say 2 days 15 hours once. As long as I don't charge it 100% the time on my battery continues to go up. I can plug it in while it has 10% left charge it till its 90% unplug it, and the time won't reset.

If anyone mistook my comment, I'm not really interested in claiming any specific record as the op as stated.
I simply meant to share my thoughts on "dataswitch" app and how I had applied it.
I think found it useful to limit data usage and to conserve the battery when I can't get a charge right away.
You'll be surprise how much battery life background data consumes.
The other part tech part of me also recognizes that battery memory exist...it may be best to "widen" your charge range (0% to 100%) when possible.

Well, I figured out what caused that.. My radio in my truck has a USB port that I plug my phone into to listen to my music. Worked great on my Ipod but it wouldn't charge my Ipod. However today when coming home, I plugged my phone in and it doesnt show to be charging, but when I looked at the Battery Use chart, it deffinately showed an increase.
And here I was thinking I was getting impecable battery life lol.
Oh well.. Sorry for the fuss. However, I will keep trying

[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

Charging Over Night

Hey guys,
Normally I would want to charge overnight, because the time other than my sleep is when my phone is near a charger or when it's not in use hahahaha . But, I don't want to charge it a lot more than it should be charged, in fear of destroying the battery (I'm planning on holding onto this phone for quite a while). So I have two questions coming from this...
1. What ways do you guys charge your phone that suits you?
2. Any ideas what could be a good way to charge my phone at night without overcharging it? I've seen some adaptors that have "30min, 60min, 4hr different charge timers" but I'm not sure if those are the way to go.
Any help is appreciated,
Thanks

As long as you're charging using AC you're all good. The current will pass back out.
