Hi Guys,
I know there's been a few threads on this, but a lot of them don't really answer what I'm about to ask.
I've noticed lately that my battery has been losing about 10% in the first half an hour, then goes down quite slowly which makes me think I need to wipe the battery stats. However a lot of people keep saying 'wipe battery stats' then fully drain, which seems like a ridiculous idea knowing what we know about how badly batteries react to full discharges (on a bad day you can actually knacker the battery), so what I'm asking is can I just wipe the battery stats at 100% without discharging. The user manual never said about fully discharging my phone when I first got it so why would I need to do it now? Also, this concept of bump charging, how would I do it on a Galaxy I9000
Thanks very much!
Breaking you battery through a full discharge? Never heard of that.

again though, a full discharge, is that wise?
You need to calibrate your battery. There is an app in the market..just search "battery calibration". Charge your phone to 100% then use the app to wipe the stats. Let your phone discharge. Full discharge is not necessary. Discharge to 1% then charge it back up to 100%. Good to go. If you don't want to use the app, you can wipe your battery stats in recovery which accomplishes the same thing.
When you drain your battery, your phone will not just stop working at some point, it will shut down your phone in an orderly fashion before you battery is fully depleted.
When I drain my battery and my phone shuts down because of it, I can still switch it on again and it will work for a minute or so after it has fully started before it will switch off again.
Could I not just wipe the stats and not fully discharge? Or does that achieve nothing. I'm pretty certain it's these battery stats. Today, it went down to 84% in seconds. I've noticed if I plug it in, it charges full, unplug, then plug in again, it starts at about 91% and does the rest. Sound like a battery stats issue?

When you charge, you phone says "charged" as soon as it hits 90%. Check the about-menu in settings (or in my case at least, the lock screen while plugged in) to see at what percentage you really are when your phone says it's charged.

Oh right I didn't realize that. I'll try it. I've just unplugged it and it immediately said 98% so I plugged back in. This time when I pull, I'm going to wipe the battery stats. I don't really want to discharge fully, because even at 1% it's not great for it. If anyone can state categorically that I shouldn't, tell me now please haha

Slight oddity with my Vibrant.
Occasionally when I charge the phone, it will show that it is completely charged--battery gauge will show full, About Phone will show 100% charge, all of that good stuff. When I unplug the phone, my battery gauge will instantly drop to 97%.
Additionally, for the entire duration of this particular charge, my battery life will be total crap. And by total crap I mean draining 1% in five minutes with the screen off, going from 97% to 78% in two hours with the only use being a quick check of bus schedules.
However, if I notice this 100-to-97 instant drop and plug the phone back in until it charges to 100% again, it will not display any of this odd behavior and battery life is awesome as usual, with standby power consumption at 1-2% an hour.
So... what gives?

Dont worry about when you unplug it, its just a inaccurate reading.
It happened to me this morning with Axura, and my battery showed 97%, but the 3% was given back without me knowing, does your phone stay at the 97 for a longer time? it should, and also some people say do a battery calibration.
its like
charge till' 100
drain it to 0
charge till 100
and then on clockwork recovery go to advanced and do wipe battery stats or something
^ im not sure someone correct me if i'm wrong about the calibration.
I conditioned this battery after flashing the ROM last month. You have the directions mixed up... should charge to full, boot in clockworkmod, delete battery stats, reboot, drain to 0, charge back to full.
And no, it doesn't stay on 97 for longer than it should; as I stated in the OP, if it does the 100-97 drop, the battery life is significantly worse than when it acts normally.
I get the same thing. Actually at the moment I am trying to unplug... see the 97% and plug it back in, it will then say fully charged, I unplug it and it says 98%. I am going to repeat this until it actually says fully charged when I unplug it and then reboot to recovery and wipe the stats.
What I am confused about when it comes to reconditioning and wiping is even when the phone says "fully charged" when I reboot to recovery and wipe, once the phone has rebooted it says it's charging again. Should I leave it in until it says fully charged or unplug it after it boots?
It seems to do the 100-97 thing primarily when charging via USB. Almost every time I've seen this happen was when it was charging off my laptop.
I've noticed also that when it does this, the battery icon (I use Segmented Battery Mod) shows "100" solid without a flashing plug icon. If I unplug it, it will drop to 97. If I plug it back in and it actually charges completely, it will flash between the plug icon and "FULL."
hmm...mine does it no matter how I charge it.

Mine USED to do thar with Nero beta 3 now on Axura IRS dine I've been using it for 20 minutes and still at 100%
Sent from my SGH-T959 using XDA App
Updated to Nero v3 and now I have the problem constantly. It will always claim 100% charge when it isn't actually fully charged.
Sent from my SGH-T959 using XDA App
If you've flashed the ROM, do the "recondition" -- or if you have a stand-alone (external) charger, just charge it full, then put in the new battery and wipe your stats. (The recondition thing -- charging, draining, then charging -- is just a theory that on the second full charge you'll get "more" charge in there after a full drain -- I doubt this is true, especially if your battery stats are hosed to begin with.)
As for the dip after you unplug it -- this is just the battery manager varying the maximum charge level to optimize battery life. Laptops do this all the time -- even when they're plugged in, they'll let the machine run on battery power here and there. For a new battery it might only let it dip to 97%. On one of my laptops it has decided dipping way down to 86% is optimal. Just depends on the battery health, usage patterns, etc.
Battery life was pretty bad when I first flashed Nero, but now that I've wiped battery stats, the battery life seems much better. It still does the 100-97/98 thing, so I'm guessing it means my battery is still pretty good despite all the heavy use!
The JL5 modem seems to have worse battery life than JK6 (only very slightly though) but it doesn't get stuck on EDGE like JK6 did... net gain in my opinion.
So I charge my Galaxy S2 to full (or at least, it says it's full), unplug it, and it says it's only charged to 60%, or 43%, or something random. I plug it back in, and off it goes, starts charging again, this time usually up to the "proper" 100%.
On top of this, the battery drain is very fast (10-15% overnight)
So, believing it's the battery, I get a replacement. Same thing.
I then learn that the reason might be because I flashed Lite'ning ROM while not on full battery, and that it just needs a battery calibration.
Ok, so I do a battery calibration - I charge it to full, drain it to 0%, then charge again. Take it off the charger, plug it back in to make sure it's full and...what do you know, the battery meter shows it at about 20% It continues to charge for about 4-6 hours after this.
Help? Is my phone faulty, or am I just not doing the calibration correct? I don't think it was like this before I installed Lite'ning ROM. So I'm praying it's not the phone itself?
The only other thing I can think that it might be, is the fact that it's a UK Galaxy S2, but I'm using it in Japan with a Japanese charger. Though I don't think that's an issue.
Any help would be very much appreciated.... not only does my battery not charge to full in one go, but it has **** life afterwards
did you try removig battery stats from recovery mode?

Yeah, that's what I meant by "tried the battery calibration".
Charged to full, wiped battery stats from recovery, then rebooted.
Try using app battery monitor widget, and check battery is actually charging it to around 4200mV, and discharges to around 3500mV at approx 1%.
100% is not full, it will continue charging for quite a bit after to around 4200.
At least you will know that the high and low scale is correct, and can monitor in between.

So I charged it overnight via AC adapter (with the phone turned on), woke up, and the phone was at 4%!
Seriously, what the hell?
Phone was indeed reading close to 3500mV via Battery Monitor when it was almost empty
Any help?
Try charging via usb, much slower than ac though, then check again.
Don't drain battery to 0%, certain reports indicate not good for the battery, others say no worries. Try 1% so the phone doesn't turn off.
Although the huge jumps in battery level indicate a battery issue; If still no good, try a different ROM, and recalibrate. Also try in flight mode overnight and check results.

Thanks for the suggestions man, I appreciate it. My main concern is whether or not it is a problem with the phone itself - the place I bought it from has a ****ty returns policy and won't exchange it or anything. So I'm hoping like hell it is something I can fix myself (new battery, new charger, different rom, etc etc etc).
As I mentioned, I'm currently on the latest Lite'ning ROM with Ninphetamine kernal I believe. Just did a factory reset/data wipe via recovery mode, thinking it would get rid of lite'ning rom and the ninphetamine kernal, but upon rebooting the Lite'ning rom theme (blue lightning on the icons, etc) is still there.
Anyway, I have it charging on USB now, and I have ANOTHER battery coming tomorrow, along with a stand-alone wall charging unit (that charges just a battery on it's own, not connected to the phone). Maybe I should charge the new battery via that for 16 hours, then stick it in the phone, wipe the battery stats via recovery, and flash a new ROM (say, the new villainrom)?
Yeah, forgot about that also, I have two SGS2 (one in for repair), and each time new have let is charge overnight without turning on before first boot. Then discharge to approx 1% (do not let it die), then charge fully to 100% and approx 4200mV. Quickly clear battery stats with Battery Monitor Widget (menu / stats / SU permission, no need for recovery as you'll waste battery rebooting and get inaccurate reading) and immediately disconnect charging. A new batt stats file will be generated.
At least with this method you'll know your at a "true" 100%.
Also, it may take a number of charge cycles for full battery potential, but don't let it die.
I use Cognition straight "out of the box" with no issues.

For the past few days my battery has been charging to a max of 92%, whether or not I try unplugging the battery, leaving the phone on the charger, wiping battery stats, and doing all that I can to try to reset the battery stats.
Anyone have any idea?
UPDATE: My phone is still not charging past 92%, no matter how long I leave it on, or what I try to do to fix it. 4167mv max
I have a similar issue, it's been like that for a long time for me. What ROM/kernel are you running? It might fix it to completely drain it, charge it powered off, reinstall ROM/kernels when it is completely charged and reset battery.
Sent from my MB860 using xda premium
drain it until it shuts off and then charge it all the way to 100%.
I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.
its most effective if you know your battery is fully charged, power it down, pull the battery, while the battery is pulled plug it into the power adapter, it will act like its starting to charge, but then instead of having a percentage, it will have a question mark. pull the power, put the battery back in, turn on, wipe battery stats in recovery and run with it...

I just started having this issue and cant wait to try it thanks for the suggestions.
when this happend on mine all i did was keep using it and it fixed itself. i ran it down maybe to 20% before I got to charge it again and it slowly creeped back up to 100%. took about a week.
I've had the problem, and have run the solution more times that I can count. But nothing ever fixes it permanently. Everytime I run the battery low, the levels get all screwy again. Maybe my phone is just worse than everyone else's, but I had to just give up on it. Would love a permanent solution, but so long as I'm running this ROM (CM7), I doubt I'll ever find one.

I'm in the same situation as you are... I had this problem for a long time now (Guess it has something to do with excessive flashing...) and no matter what kind of solution I do (Wipe battery stats via recovery, re-calibrate the battery, pull the battery out while charging and replugging it) it returns after a day or two.
I want to check if it has something to do with the battery or the device, and if I will remember to do so, I will plug my spare battery for several day's run, but that is subjected to me leaving the comfort of my usual laziness....
Would love if there was a permanent solution as well, thou I doubt that too....
I've had the same problem on a number of different roms and at different times. I find that instead of mucking around wiping stats etc, it has always come good eventually for me.

Didn't really understand what you meant, did the battery percentage fixed by itself and gave you 100% at full charge on one day? out of the blue?
Or did you just got used to have less then 100% battery display?

First let the battery completely drain and the phone shut down by it self. Second step is to pull out the battery and leave it out for 10min, after that take a plastic bag and put the battery in it and place it in the freezer for 15min. after this palce the battery again in the mobile. make sure there is no any moisture on the battery. Then charge the phone without power on till 100%.
By following these steps this will made your battery to charge fully and more talk time

Um correct me if I'm wrong anyone, but doesn't cold kill the battery and shorten its life? I remember my mom always putting new batteries in the fridge and them only lasting a couple days compared to the ones left out that lasted a month or so with same use.

Haha, I got a good laugh out of this one -- you've got to be joking.
I've had this problem for a quite a while now with the Atrix and two different batteries. I've tried dozens of combination of resetting the battery stats, running the battery completely down, and powering up without the battery and hot swapping it in. The hot swap definitely allows me to finally recharge to 100%, but once I run it down again, the problem returns. I've learned to just live with the less than 100% reading -- battery still seems to last a full 24 hours for me.

That trick hasn't worked since nicad batteries in the 90s, and is a really bad idea with our Li-PO.
Drain the battery till the phone shuts off, charge back up while the phone is off.
If it still doesn't get to 100%, boot into CWM, wipe battery stats and power off the phone to let it charge again.
^^ I know it works because I've done this like 2 days ago, and many times before that.
I have had this issue as well for a very long time. I've tried the pull out, question mark, 5% thing and it usually only works for one cycle, then the next only goes to 97%, then the next to 93%, then 90%, and it continually goes down until I have to do it again. Hopefully a permanent fix can be found soon. I've tried clearing battery stats, draining it to 0%, then charging it fully. I've tried everything. As far as I'm concerned, there's no fix as of right now.

★ATTENTION! I FOUND THE FIX!★
Turn phone off and plug it in to a wall charger. Charge it until your notification light turns green, quickly tap the power button to check battery level. (Usually shows 90%) If the notification light turns on, but the battery indicator is not at 100%, unplug phone, take out battery and put it back in. Now plug your phone. It should be 100% now. For the final fix: go into "Android Recovery" and select "Mounts". Mount Your SD card and Emmc. Finally wipe battery stats. Reboot phone.
This method worked for me. I am 100% sure this is the fix for this problem. This has to be done every time you flash a new rom or when your phone freezes and you screw up calibration by pulling the battery while it is still on. BTW, this is my first post so don't be mean to me!

Drain all battery and charge it from zero. Let it be fully charged before starting it. If you run CWM you can wipe battery state.
Your question is in wrong section in the forum. Try starting the thread in General.
Cheers
+1 this -- and some additional detail...
Wiping battery stats does NOT improve actual battery life. If done properly, and coupled with a calibration cycle, it can increase the accuracy with which your battery reports its current charge. Ideal process is as follows..
Charge to 100%
Reboot into CWM
wipe battery stats under" advanced"
Reboot
Charge back to 100%
Let it DIE (go to 0%) from normal use, DO NOT charge it during the cycle
Re-charge to 100% and you're all recalibrated.
From the sound of it, don't be surprised if your phone sits at 5% for hours. After the calibration, your battery history should be a relatively smooth, downward sloping curve.

Check Settings>Battery Information>Battery Usage and see if a process named RILD is using a high percentage of your battery usage. That process - a very necessary Motorola radio daemon - is wreaking some havoc by causing very rapid battery discharge and also preventing normal charging.
No solution for you but thought I would let you know before you try too many different "solutions" needlessly.
Thanks!

Hey everyone. I'm having an issue with the battery stats of my Acer Liquid Z500.
When I charge my phone, sometimes the battery stat freezes at some point, 35%, 28%, 45% for example, for some time. When the phone feels like it's discharging, the battery stats come down really fast, like 1% per 15 seconds, until it's off.
I've tried booting into recovery mode and checking if there's any option to wipe battery stats, but there's not.
I've tried factory resetting the phone but it doesn't work.
I was wondering if you guys could enlighten me about this issue. It's getting really annoying.

Had the same problem once on a different phone. What I did to solve this was quite simple: after battery percentage has frozen, I shut off my phone completely, so it can charge without interference. So just wait until the phone has charged completely. Another option would be to perform a simple reboot after the freeze.
If this doesn't work, maybe you have to re-adjust your battery by charging it to 100% and then let it discharge to 0% and then do a full charge afterwards.
