I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks
Dear Android Community,
Overcome-day to all!
I've upgraded to "Overcome-Jupiter" 3 days back and though admittedly the new ROM is smooth and fast I believe am noticing some irregularities on the battery.
I have a question and situation, wherein in battery statistics is is show that "Display" is using around 96% of the batter, all other task including the "Android system which is only 2% is for the remaining 4%.
Furthermore for a full charge, am getting around 14-17 hours usage on the batter.
I've done a "battery wipe" and have done two discharge cycle.
Any other Galaxy tab7 user here having the same issue, your comment, suggestion and recation on my query is greatly appreciated.
Thanks in advance.

As for display that is normal since Froyo especially with heavy use, the beast display consumes the battery more than anything. As for the battery life if its on moderate to heavy use that seems quiet normal even good actually (remember official stock firmware gives you 7hrs on heavy use). Finally read the tips and tweaks section on our website for more info.
I have heavy drain on the battery after upgrading from Hermes to Jupiter. (All apps and setting being similar)
I can get only close to 5 hours of continuous usage compared to about 7 hours on Hermes. You're not the only one to be affected...... I've posted my cries for help :
http://forum.xda-developers.com/showthread.php?t=1176978
I'm still monitoring to see if there's improvement after a few charge cycle.
Darkpal,
Thanks for the quick reply, I have to agree with you on the display thing. What I wanted was actually, just a confirmation from other users that they are having the same battery statics. This will then confirm that everything is normal with my "precious/fragile SGT".
I will do further testing and monitoring.
To PCdumb,
Cheer-up buddy, still I believe our SGT is one of the best tablet out there. ADB and the Overcome team can only do so much nho.
To Darkpal,
On a final note, will the "app lucher" (am using "go launcher EX") will have and effect on battery usage, any launcher you can suggest.
Thanks again for the help
Launchers if coded correctly shouldnt have that much impact if at all on the battery. I personally am using the stock launcher only because am too busy or lazy to configure ADW launcher EX which I have an recommend

battery % weird
Hi. I have a strange question in relation to the topic. I use a P1000 running Gingerbread (stock no mods). I hope you guys have some solution to share to me.
I had Battery Monitor installed so I can check the battery usage and percentages, and Juice Defender Ultimate to you know, save juice.
1. There are few instances that when the unit still has 10% or below power, I sometimes encounter unit shut down (powers off) while I am browsing. So I turn it on again, the Samsung animation appears, but still turns off. Therefore I am forced to charge it (using mains plug). Is that normal?
2. Coming from a critical low battery (5% or lower), with the unit off, I leave it charging (using mains plug) until the battery goes full green (full). 4 hours or so if I am not mistaken. When I turn it on, Battery Monitor displays only 76% or 81% power.
I find that strange since it is supposed to display 100% right?
3. At 76% or 81% while unit on, I plug it to charge again, but does not increase percent anymore.
4. Upon my gut assessment, the unit still performs normally, the standby time and usage time are still as expected, the battery is working fine.
TO DO:
I am thinking to just clear data and reinstall battery monitor.
I am also thinking to install another battery application to display percentage for comparison.
In any case, is there a way to calibrate the unit when turned on to display 100% when it is really full when charged off?
I am not modding or rooting it, I am just a basic user. Any ideas? Thanks!

Try to reflash or factory reset then monitor the battery without installing the battery monitor.
I use "battery doctor to save battery" from the market. You can try that but try first without a battery monitor app.
did you try to use another usb cable? or perhaps your charger is not the original? loose internal battery connector? there are so many factors that might cause your problem not mentioned.

Thank you for the reply bongski. Without any battery monitor app, the problem is I cannot see percentages. But anyway I will do the factory reset, it is another option but I find that drastic and will be the last choice. Also, the USB cable and the charger is the one that came with the Samsung box so they're original. The loose internal battery connector is a bit far fetched, the battery is not user accessible and also the unit is not dropped and carefully handled.
Hopefully I get accurate readings, I will update here.
The battery percentage is in settings/about device/status/battery level.

ok. well i did the following
1. clear data and reinstall battery monitor.
2. install another battery application to display percentage for comparison.
i tried the battery doctor but provided the same percentage reading.
so i just factory reset the thing, and i am observing now (ie. charge later and see if the issue persist). i've no knowledge on how to reflash the thing.
well ok to clear all my doubts i just factory reset it. then i reinstalled my initial apps (including battery monitor), used it til it died (1% until it off itself). plugged to mains, turned it on, and let it charge while ON (of course screen is off). took 174 minutes (3 hours) when it reached 99% and stayed 99% (looks like it does not touch 100%) 4176mV. after 5 mins of non use, it still remains 99% but at 4012mV. with the 1% missing, i guess i can let that go and dismiss as normal now... although i read related thread
http://forum.xda-developers.com/showthread.php?t=866011
and some resetting technique here
http://forum.xda-developers.com/showthread.php?t=921848
but anyway my simple mind would just like to say, "ok its displaying normalcy now".
now i did not figure what caused the tab to display erratic behavior before this, but once i got it i will update again.
Hello all,
I'm having a weird battery problem and am not sure if it is software or hardware. Basically, I have charged and it will last about halfway through the day. I'll look at it and between 50-55% of battery life it will turn off and go dead. I'll turn it back on and the battery is at 0% - no warning or anything. I have to then charge it back up and it seems to take a while from 0-25% and then it will skip to 90% and finish charging to a 100%. I've tried several different roms and all are giving me the same problem - currently on oxygen 2.3.7
How old is your battery, and is it a stock battery?
You may want to calibrate your battery. There is an app on the market that is specific for the N1 and instructions for it can be found http://forum.xda-developers.com/showpost.php?p=9583271&postcount=340
It isn't the easiest thing to do, but if you do have a decent battery (some cheaper knockoffs don't have support of figuring out your battery age), it can get your phone to properly detect your age of your battery and show the correct stats for it.
As for it dying half-way through the day... have you checked to see if apps are chewing up your battery time? If they aren't, it may be time to get a new battery anyway.

It is the stock battery I got when I got my phone in May of 2010, so I can expect to be not as a good as a new battery but it's bothering me that i can't have a an accurate reading on how much battery I have left. I feel like I have half a battery left and then all of the sudden it will die. I'll try the calibration and see what that does. I don't think its apps because I've flash and reflashed my phone and never have many apps as a result
it was revealed by "Dianne Hackborn" from google android team a while ago. i'm posting it here because some of p970 users still doing this calibration thing.
here is the post:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

lol you got it all wrong. he says that the battery indicator has nothing to do with tje battery stats app and then explains whar battery stats app does. this has nothing to do with calibration and if you still think calibration is useless then do a simple check. after a period of not calibrating your battery and using your phone heavily (2-3 hours of gaming for example), or even better after using your phone extensively while charging, let it go to full 100%. At that point when the phone thinks that it is full it stops charging cause the integrated safety tells it that it is full. turn off the phone remove battery for a couple of minutes and then insert it and plug it on charger. you will notice that it is charging again. turn it on withou unplugging and see the battery level. can be as low as 80ish %. which means that if you hadnt done that all that juice would not charge and be left unused. try it...

Well, no, actually you did. What she said was that deleting the batterystats.bin does nothing more that resetting the battery usage tracking. She also said what's in the file and it sure looks like it could not even be used for anything else. You could check the code to see. Otherwise, just trust her.

yeah but calibration is not about battery stats. is about geting your phone to understand that it is not fully charged yet even though it thinks it is. try what I suggested and you will see. the apps for calibration do nothing as they say when it is fulmy charged leave it for some more till the program tells you it is ok. actually when phone perceives itself as charged it stops charging so those programs do nothing. It is all about forcing it to fully charge once in a while (I do it once a month) by removing battery once it says it is charged and reinserting after a few minutes and recharge it and then repeating until the time that i plug it and it wont charge anymore. wiping battery stats is NOT calibrating never was or never considered calibrating. and the thread was about how calibration doesn't work (which does) not about how battery stats wiping doesn't work (which it doesnt)... so if op doesn't distingush between calibration and battery wiping and refera to the latter as the former then it is not my fault. To sum up,what the op said was that we shouldnt do calibrations because wiping battery stats doesn't work and what I said was that battery stats has nothing to do with calibration.
i'm not android veteran. but when i came across "batery calibration" term, it means "removing batterystats" at this community. so, i gues my point isn't that wrong.

well unfortunately it is not. by all means try what i said and you will see that although your battery appears charged it will charge some more and again and again before it stops charging and is really full. if i doesnt then it is calibrated if not it getsvcalibrated when after inserting it, it wont charge anymore. then after some time again (maybe a month maybe less) you will see it happening again. trust me batteries is what I make a living from.
I don't see how calibrating could hurt so if you think it helps do it. If you don't, then leave it. I did it after flashing and no ill effects.

That's just plain wrong. Shall I link to a few respected "battery calibration" tutorials that revolve around deleting the batterystats.bin? Heck, there's even an option for it in CWM Recovery.

I have done and still doing a lot of reading in this regard. The battery stats can only be held responsible for calibration if it holds amperage and voltage values set for the phone stock battery. That myth is currently considered debunked as this file is considered only to be linked for UI purposes. It all comes down to how actually does the phone measure the battery level. If there were in-built values for voltages and current, the concept of plug and play extended batteries would be doomed and they would have been accompanied by a detailed calibration process. Then there is also the discussion of Max 17042 (I am a SGS2 user), the fuel gauge chip and how it works. Frankly, I think we first need to understand how the phone measures the battery and against which parameters, are they preset or change on the go and what are the limits.

I was trying this method just now and what happened was after i got the 100% signal, i unplugged the battery and after giving it a rest of few minutes, plugged it back in (a new 2000 mAH extended battery by Samsung). When i l plugged in the charger again, it start charging back showing that there was either power leakage or that is what calibration is all about. Did that two three times and when finally switched the phone on, it was 100%.

You are doing what is needed to reach real 100%, a second charge cycle, see article.

As stated there it will reduce battery life but increase runtime after charge...
There's nothing good without evil ;-)

if you got clockworkmod recovery charge your phone to 100% (8-12 hours charge should do) then go to your recovery then select advanced then there should be option for wiping battery. Hopefully it'll work!!!
Hey guys, its my first post on this forum (or on any forum for that matter) so I apologize if this is in the wrong section . But recently I've been having a problem with my S3 mini and hoped I could get some help on here. So a few days ago I got a 4000mAh - 3.7V extended battery for my phone because my old one had broken. The old battery was the stock battery that came with the phone. Before I bought the new battery I also installed the PacmanROM on my android. But since I got the battery the percentage my android displays has been completely wrong. I'm pretty sure that the battery is fully charged after over 16 hours of charging but the percentage the phone displays is only around 65% and no matter how long I charge it the percentage never reaches 100 and it will stay on a certain value that will randomly fluctuate if I restart the device. So is there anyway to make my phone display the correct percentage? Thanks for your help!
In my opinion, extended batteries are more trouble than they're worth. I have dabbled with them but all have failed at some point (even brand new). If you put the battery on a flat surface and it 'wobbles' at all then its duff. I use stock batteries. Sorry if this is not what you want as an answer but just my experience with extended batteries.
Sent from my GT-I8190N running CandyKat
Thanks for the input anyway! I've never tried any other extended batteries so I ignorantly decided to get one hoping it would work well. But anyways I believe that its not the battery that's at fault since the battery seems fine to me (no bumps showing a faulty battery). I have a feeling that its my old battery that's at fault or the system still possibly assuming its a stock battery. Well I'm no expert .
Awfully I can post the link for fix this..
The APP for fix this 'bug' is "Battery Calibration", it delets a battery file, and after restart the cellphone, that file is remade with correct data.
Well I looked into Battery Calibration and have managed to find a fix! I charged my phone to "full" (which my phone only displayed as ~50% at the time) and once the battery percentage stopped increasing I left the phone to charge for a few hours after that. Then when I was sure that the battery is actually full, I installed a battery calibration app and "calibrated" my battery which deleted the batterystats.bin file. I then waited for my phone to completely run out of charge, which I sped up with an app called "battery discharge", then when I let the phone switch off by itself from an empty battery. Once the phone restarted the battery percentage displayed was correct.
Try Battery calibration
isnt battery callibration a complete myth and placebo? deleting batterystats.bin shouldnt help as it just contains data about what consumed battery juice
