Question: Does anyone know if it's ok to boot on Clockwork and wipe the batter stats? I flashed my phone last night to midNIGHT 2.5 w/ext4 with low battery charge and this morning within 2 hours of unpluging it from a full charge I was down to 18% and pretty much all I did was listen to music for about 30 minutes total time. Any thoughts? I'm not running a bunch of apps or widgets and Im using ADW launcher Ex
You should have a full battery before you wipe battery stats.
Try this:
Charge with the phone on until 100%
Turn the phone off, unplug it, plug it back in and charge again until it is done.
Turn the phone back on, unplug it, plug it back in, and make see if it is at 100%
Then wipe battery stats.
Or if you have an external battery charger, just charge and bump charge a time or two, then wipe battery stats.

Since applying the 1.47... OTA, I can literally watch the battery drop minute by minute while the phoe is active.
Within the first 1 minute of removing the phone from the charger the Battery Status Pro reports the charge droping from 100% to 97%. That's a 3% drop in 60 seconds.
Within the first 3 minutes of active use BSP reports the battery drops to 93% charge. That's 7% loss in less than 200 seconds of use.
Now I'm not saying BSP is 100% accuerate but I expect it's not too far off.
Battery life with the Evo has never been phenominal but this seems rather extreem. The drop seems far faster now than when running the 1.32 release. And... while I am in a 4G enabled market, this is with 4G disabled and the phone running purely on 3G with no flickr, twiter, facebook or other feed widgets running and autosync disabled for all of them.
When I look at Battery Use under settings / About Phone / Battery the Android System is by far the largest user of battery, nearly twice the next closest user which is Cell standby.
Am I the only person experiencing this?
The phone was doing this before the 1.47 OTA, it's a problem with charging the battery in the phone. It does not charge properly for some reason and it will drop all the way down into the 80's within an hour of unplugging it. If you get an external battery charger and use it to charge the battery the phone will stay on 100% for an hour or more...
Have you removed the HTC people widget from home screen? The day I removed that was the beginning of decent battery life. Also try turning off the phone when charging - seems to work better that way.
I would try charging to 100%, unplug, wipe the battery, plug it back in again until the light turns green and try again and report back.

I wondered if it was the powered off portion of that battery trick that was doing it. Hmmm. I'll have to watch. Is there any link/source on the idea that the phone itself is not working so well at charging?
Out of that voodoo on the getting better battery life the only thing I could come up with was...-charges better when off, - you need to charge for a bit while on to reset the battery indicator, - and charge a bit while off to top it up.
So I was leaning toward it being a charging thing and not a battery thing...would like to see any technicals though and not just my guessing.
People widget has been long gone.
I gave the charge it with the phone powered off thing a try. The device was down around 80% charged when I powered it off and plugged it in. In about 5 minutes the charge indicator turned from amber to green as if it were fully charged.
I can't believe that the battery charged 20% in 5 minutes.
This leads me to believe that the first response is correct. The battery simply isn't charging fully in the phone. I believe I'll look for an external battery charger and give it a try. See if it makes a difference.

Seriously, try full-charge, wiping your battery data and then shutting it off and 'topping it off' and reevaluate the situation.
EDIT: The "topping it off" thing is all voo-doo as far as I'm concerned. I just do it to be safe, though I'm pretty sure it's ineffective.
I screw with my phone so much, so much flashing/restoring back and forth while on charge, between
charge, car charger, USB charge at work, wall charge, flashing again, kernel swap, restore back again...etc etc etc...that if I don't wipe my battery once I hit a full charge there is no way I can trust that meter to do anything more than change colors. I do it every few days when I notice the meter isn't being trustworthy.
If this doesn't work for you I'd say you probably have a bunk cell in your battery, and failing that your phone just might not be charging well.
Also, charge with the wall and not USB. USB takes forever. And 20% in 5 minutes isn't TOO far off if you are plugged into the wall and getting full-power charge. Maybe 10-12ish minutes, unless you were timing it very specifically....
I just got my bricked replacement. Here is the data from a 100% charged battery usage up time 18:13 .. Awake time 15:27 the battery is at 87%
funny im getting 20 + hours a charge after the OTA
with heavy usage
I have allready read:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

My question is dose the phone need to be off or on for stage 4 the recharging of the battery?
If it can be off for stage 4. Dose it need to be charged in one sitting or can I charge it partially then take it to work and then charge it the rest of the way before I turn the phone back on?
This my second attempt at doing a battery stats wipe. The first time I tried I left the phone on wile charging and the battery only charged to 3800mV calming it was at 100%. I had to bump charge it 3 times over 3 hours before the battery was up to 4100mV-4200mV and clmaing 100% charge capacity.

1) You can have it on
2) NO! charge it from 0-100% in one sitting
I did it according to the above with my 1&2 and im getting accurate readings now as well as the battery life i should have.

I wonder if this means that I will not be able to have proper battery stats as my phone likes to stop charging and claim that it's at 100% when its actually at 50-80%/ (It dose this 95% of the time... It even did it with the stock battery stock battery a couple of times)
Hi all
since a week or so i have a strange problem with my sgs and i hope you can help me to fix it
Everything works just fine (battery is accurate) until i switch off / reboot the phone
but at next boot the battery reports a very low value
(e.g. the phone has 55% battery left and after the reboot it reports only 8%)
with Froyo 2.2.1 (Speedmod Kernel) it would stay at that level until the battery has really drained to that point
With GB (JVQ - Galaxian Kernel) the battery percentage increases slowly
What i tried so far:
first of all, i deleted the battery stats for a few times and because that didn't work i upgraded to JVQ (with repartitioning and all), but that didn't solve the problem either
i don't really know what to do anymore and i hope someone can help me
thanks
Just do a few drain/ charge cycles and that should sort it

First off, wiping batterystats.bin alone won't help.
Try this:
1. Charge to 100% until it says unplug charger.
2. Wipe batterystats.bin from recovery, unplug and then reboot
3. Drain your phone's battery until it shuts itself down
4. Charge to 100% without interrupting the charge
5. Enjoy :3
thanks for the quick replay!
unfortunately thats basically what i have already done
since the problem happened the first time, i have charged the phone at least 5 times and wiped the battery stats for 2 or 3 times right after charging the phone to 100%
its true that normally i don't drain the battery completely, but yesterday i have done just that and than let the phone charge overnight - but that didn't solve the problem
i will try to fully discharge the phone a few more times and load the battery while the phone is switched off
still i hope someone has an other suggestion how to solve this annoying problem
thanks
lol - stop deleting the batterystats.bin for starters.
The batterystats needs to indentify the top and bottom markers such as 0% - 100%, delete it ONCE.
Firstly, turn the phone off, charge the phone to 100%, bump charge it, till 100% truely.
This means, unplug...then plug it in again until you keep getting 100% show up.
Boot up into recovery then delete the batterystats.bin.
Use it heavy, activate everything and drain it. Make sure it is compeltely drained, try turning the phone back on, take the battery out for about 2 mins, try turning it on again, if it doesnt turn on, you've drained it.
Plug your charger in, do not turn the phone on, let it charge to 100%, again, bump charge it until 100% truely full, turn the phone on and let it run its natural course this time.
Do not delete the batterystats.bin again, you will have to repeat the process, it will take a good 2/3 times of charge/discharge for the stats to settle.
Hopefully helps dude! Good luck
thanks pidz!
just to clarify: i have had my sgs for a half year now and i never wiped the battery stats until last week
But i haven't tried bump charging jet - i really don't like that process as it is bad for the battery but might be worth a try, thanks
it usually happens with non original batteries. did you changed a battery? or maybe you got a fake one with you phone?
Even after installing cm7 I would get about 8 hours of use out of my kf. One day It would only charge to an indicated 90%. So I let it charge overnight, cleared battery stats, and let it run until it shut off. I let it charge back up but now I'm only getting bout 5 or 6 hours of use.... suggestions?
I have Aurora ICS in my U8800. Yesterday I removed SIM to another phone and turned U8800 back on. Battery level was 80%. Listened music, used wifi a little bit... and today, 12 hours later battery level was still 80%. Reboot, and now the battery level is 40%. Plugged in charger and two hours later level was still 40%. Reboot, and now the level is 100%.
What part in Android system handles battery level changes (and updates changes battery indicator). And why does SIM play any role in this situation? And most important question now is how can I refresh charge level without rebooting (and without SIM of course)? Tried some battery widgets from play store but without luck...

just charge your phone for 3 hours, i think that should be enough for full charge.Do not unplug it, Go to recovery wipe battery stats, and leave it plugged in for another half an hour. that should solve it.

not everyone have clockwork recovery my friend
anotherway to resert battery stats its free apk calld battery calibration
here is link
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
it needs root.
best way to calibrate battery is fully charge then unplug restart device plug in charge till 100% and do it again over and over for 3 times then... calibrate battery
fully discharge and charge again till 100 w/o breaks
Ok, tried that what rjspark89 suggested. No help.
But when I inserted an old, deactivated SIM-card into phone, everything worked fine.
So, something is not working the way I think... Now using U8800 as PDA for a while. No phone but BT and WIFI are working, and battery charge level changes as expected. Case closed
(and yes, I have Clockwork Recovery in my phone, and battery calibration app(s) are familiar too)
