Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati
bad phone ? my ext batterys work fine from ebay
is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

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

Darkpal,
Thanks again friend/sadiq,
Am hearing good review on "ADW launcher", i'll try this and will let you know if there will be any improvement in battery consumption.
Again thanks and best regards;

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.
Hi guys, my battery has sarted to read 100% after only a few minutes charging. The only way I know if it's charged 100% is to charge when the phone is off. I was wandering if anyone else has experienced this and knows how to solve it.
Thanks

The battery guage isn't the best. I rebooted my phone this morning and it went from 96% to 14%
About a minute later it was back where it should have been.
try to charge with the usb cable. i have this issue only with ac charger.
You could always try the common cure-all, deleting /data/system/batterystats.bin when at 100%, but I doubt it will help.
I also have this problem, it is since nightly 105 or something. Never had it before. I use the original charger, it read 100% after a few minutes of charging. When you unplug the device, it falls back to the real reading. So you never know when it is fully charged. I already deleted the battery stats in cwm, but it did`t help.
Seems like last 20 or so nightlys have battery issues......

Updating to nightly 117 seems to resolve the issue, although I don`t know which comment it would have fixed it.
it's ROM issues.. tried few ROM and these kind of bugs happened..
Try changing BaseBand and/or Ril

Note on Li-Ion cells / battery stats
Battery life is based on the voltage detected usually on the "3rd pin" which is standard on all Li-Ion packages as regulation. Now smartphone and all electronic devices that use these single (or multiple) Li-Ion cells usually make an estimate on battery life based on the degree of discharge based on the use you make of the device during the day. Having said this, there are 2 possible ways to show battery state of charge:
1) based solely on voltage. Full battery reads 4.2V, dead will be below 3.3-3V depending on vendor. However this means that device on-time is tighly connected to how much apps you run/screen/wifi/3G usage for ex.
2) based on voltage AND usage statistics. Software monitoring will store battery statistics in a file and use them to update the battery guage accordingly so battery charge status reflects more averagely the time you have left based on your daily usage habits and battery freshness.
If you delete the battery satistics file and you still get erratic readings, either there is a software bug in the battery guage integration software readings or you may have a problematic battery cell. The simple way is to swap batteries and see if the problem is gone or not.
Note on Li-Ion cells: the cell's have a limited number of charge-discharge cycles meaning the more you reach complete discharge before charging the shorter their life span. Better charge your cell(s) everytime you can which will increase their lifespan. Avoid overheating the cells which will also decrease lifespan. If heavily using the device, keep it powerer on usb or external charger.
I was just wondering, if i accidentally calibrated my battery when it was at 60% will my phone now never get the full use out of the battery? or if i charge it all the way and calibrate again will that fix it?

Just do it again when your battery is at 100% and it should fix it.
Download a widget from Android Market that shows your current flowing to your battery.
Like Currentwidget...
If you calibrated on 60% your phone will now show 100% when it actually is not full...
Best thing to do is to leave it charging for minimum 3 hours, unplug the charger and then replug and use the Currentwidget to monitor your current...
The moment that the current goes from positive (green numbers) to negative (black numbers) you need to recalibrate your battery.
Then you will have the real 100% back...
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.

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
