every night i charge my phone and when it says its fully charged i look at the batter indicator and it is only charged to 96 and wont go higher...also i have terrible battery life i cant go through the whole day without having to charge it atleast twice.
any one know whats the problem or anyone having a similar issue and would like to share any thoughts?...thanks.
Read some of the prior threads. I'm pretty sure that there is a monitor built in the Epic that prevents overcharging/overheating of the battery.
Calibrate your battery
Sent from my Epic 4G
Happens to us all I think.But I have seen 100%, very rare.When I first noticed it not charging to 100%, I would turn off the phone,plug in,wait for full indicator,unplug wait 30sec,plug in again,wait for indicator,unplug and reapeat.After all that would only see 98% when I booted up.So when I say its rare to see 100% believe me.I actually now change my framework-res.apk 95-99% battery icons to 100% icons in every single rom I use just to see 100%,and Im not kidding.But when it drops from 100% to 94% in a second while Im using it is kinda depressing,ha...and calibrating the battery does not help this.

also make sure you are doing the airplane mode toggle, what is your time without signal under cell standby? (go into about phone, battery use)

Can you elaborate on this (for fools like myself)? is there a trick involving airplane mode that improves battery life?
also, i've tried calibrating my battery, but when i choose "wipe battery stats" in recovery, nothing happens. any ideas?
thanks!
You shouldn't see anything happen when u clear battery stats. (if you're not doing this already) it's recommended that you charge to 100%, then clear stats, let drain to 0%, then charge back to 100%

If u go to settings, about phone, battery use, cell standby, it should show time without signal and it shouldn't be more than in the teens...if its like 50% u need to toggle airplane mode and that should go down and improve battery life...there's a thread on this site about it...

Take a look at this article I recently read. It does a great job explaining how batteries, chargers, and battery meters work on our phones. also does a good job of explaining why it's ok our phones only charge to 97%, or immediately drop when we unplug them.

Has anyone else used the batterycalibration app from the market?
I found that after using it my battery life is worse! I used Juice Defender before and after using this app, keeping the settings exactly the same, and noticed the following changes after ensuring 100% charge at night, the battery state in the morning was/is:
Before using batterycalibration - 99-100%
After using batterycalibration - 93-95%
Nothing else has changed as far as running apps is concerned so I can't understand why I now have this drop in battery. I've also noticed that the battery drains a lot quicker after using this app (only used it once). Juice Defender used to do a very good job of managing my battery but after using the batterycalibration app I'm not seeing any benefit, in fact totally the opposite.
Have you tested batterylife by timing it yourself? Batterycalibration obviously calibrates your battery. It corrects the displayed %. This means that before, when it said 99%, it could have been 93% as well, but just said it was 99%.

The app sucks. I calibrated with the app and then calibrated the proper way and the proper way took an extra 30 min to completely charge.
Never use the app. Just charge till green. Unplug and turn off the charge till green while off. Then once green unplug the phone and turn the phone back on let it boot up completely then turn off again and charge till green or ten minutes whichever is longer then unplug and turn on and go into cwm and clear bat stats. Restart phone and enjoy

I was going to do this (bump the battery) but seen quite a lot of posts here, and other forums, where people have seen worse battery life and, in a few cases, their battery dies and becomes totally unusable. Might give it a go though, once I get a spare battery.
Hi Guys,
Speaking of battery calibration I am about to go travelling for several months with my desire and have 4 batteries to take with me. Is there anything imparticular I should consider when charging/swapping between these batts in terms of calibration. I also have an external battery charger I was going to use to charge them the majority of the time.
Any help appreciated.
Cheers

I always use this app and it works great. It just erases the batterystats.bin file.
FYI, HTC actually used to recommend the above mentioned technique but have now warned against it as they say it is terrible for your battery's health.
Works wonders for me, use it on 3 devices, and have had no problems.

I flashed original rom but my battery behavior is still like on 2.3.5 RC4. Charge to 99% and drains very fast. Did someone know how to get back it original life. I tried battery calibrators from the market and battery wipe from clockwork mod but no result
If your optimus is old it is normal that battery life will get worser and worser ... All you can do is get new battery of ebay like I did and now my battery life is normal ...
Mike
It's not old. Its younger than a year. Battery life was good and on swift it last long and charge to 100% but after last time i flashed 2.3.5 rc4 i calibrate it (to try it last longer like on other roms) and now even on stock it drains like on rc4 and not charged to 100%
Use spare parts to see is there app that drain battery.
install "batterycalibration" from market, charge to 100% and calibrate your battery for this rom
Yes i download two battery calibration programs but the problem is that it's not charging to 100% but to 99% and drains very fast after this. i'll calibrate it a few days hope to fix
yeah, that happens to most people.
unplug, use a few seconds or 1min or so and plugin and wait if its fully charged, it could be that you have to do that a few times (2-3x)

Your not alone on this, same thing with me.
I have ordered another battery from ebay but dont really know why all of a sudden this just began happening whilst using the same Rom which I think has something to do with it.
I use a program from Market called Android Booster to terminate running programs that start up or dont close once started, as sometimes if you use your camera, it will be still running, even if you close it up so hence battery life turns crap.
But also, if somebody phones me for 5 minutes this also nearly drains my battery, and I have everything also turned off. (WLAN, Blutooth, Data, GPS etc).
So dont know why this is suddenly heavy on the battery as it never seemed to do this when first installed.
There you have it, your not alone but think I will migrate to another or buy another phone as I think its pathetic to have to charge one's phone everyday, or twice a day if you chat to somebody for 5 minutes as it defeats the purpose.

Try charging through the wall charger instead of through the USB port on your pc. Worked for me then, recalibrate.

I got my brand new battery and even charged it up via Power Supply from the wall.
Have run the phone only on 2G network only box ticked and everything else turned off (and I mean nearly everything) and for whatever reason, the Battery new or old still does not last long.
Even after it charges to 99% says its charged, it discharges very fast, or if somebody phones you and you only talk for 2 minutes the battery drops to like near 30% which is pathetic.
Something is sucking the life out of the battery folks with these Rom's so can somebody exactly put the food on the table here and say, whats up?

What ROM are you using? It takes some time to charge up the battery and even if it says '99%' that doesn't always mean that it is. What is the capacity of the battery? I'd say charge it for about 6 hours and see then.
Thanks Johnny,
Problem at present seems to be solved now.
Yesterday and before I had been using Mur4ik's CM7 2.0 RC4.
I then uninstalled a stack of apps that I only used every so often and now its like back to normal so I guess it must have been those apps installed.
Folks here is a big tip. Uninstall Apps to test your battery to find out which one is the Energy Hog because even if you are not using them, they seem to be running due to either bad programming of the app or a system management issue related connection between the two.
Now, I have just updated to Mur4ik's CM7 2.0 RC5 and will certainly think twice prior to installing a bunch of things for the sake of installing apps.
Cheers people~!
So, I am using MIUI 2.1.12 with LorDModUE 8.6 CFS 2WCR kernel.
I have installed 4EXT Recovery Controller and CurrentWidget.
With CurrentWidget, I monitored the battery while charging until it reached 0mA (which means the battery is as full as it can get).
With 4EXT Recovery Controller I removed the batterystats.bin file.
I drained the phone until it shut itself down. Then I charged it (without powering it on) until it was full (LED was green).
I power on the phone... 99% battery.
I plug in the charger... it says 26mA (which means it would reach 0mA as in full charge in another 20-30 minutes).
WHAT THE HELL?!
This never happened while I was using the default CM kernel included in MIUI. Only happened with Tiamat and LordMod.
--
Seriously, guys, what is the best way to calibrate the battery?! Perhaps I should not have let it shut itself down, but plug the charger when the phone was at 1% (which lasted for another 20-30 minutes, by the way)?!
if I don't remember it wrong the LED turns green at 90%.
afair the battery doesn't get charged during booting. which means that you probably lost the 1% during boot.
I also used the same method and got it calibrated correctly
but is their any other way too ?

The LED turns green on AOSP ROMs at 90%, when the phone is ON, as far as I know. When it is OFF, it works fine (goes green at 100%).
I want to hear from the developers / those that know how these codes work and stuff... Cause I don't want to look at my phone how the percentage goes down so fast, then, when it reaches 10%, I can play Pocket Legends for another 20 full minutes -.-

The battery doesn't charge to full capacity first time around. When I used to calibrate the battery I would charge until it was drawing 0mA, then reboot; it would be drawing about 26mA, so I'd charge to 0mA again and reboot; it would now be drawing about 15mA, so I'd carry on charging to 0mA, reboot, repeat, repeat and repeat until it eventually continued to draw 0mA after a reboot. Then I'd delete the batterystats.bin file.
As one of Google's engineers says, deleting your battery stats isn't going to improve your battery life. I haven't done any of that for a long time now and I've noticed precisely no difference (except for the extra time I've gained by not having to wait for it to finally charge up to full capacity).

I know about Google's statement.
The battery would drain fast, then, when it reaches 1% or 5%, you would be able to use your phone like it had 30%. Just that it shows the values wrong. Calibrating the battery should fix that...
Anyway... I'm not going to struggle any further.
I'll tell what I've done;
- I have installed Battery Balibration app and CurrentWidget,
- Waited battery charging till reached 0ma,
- Removed battery stats and restarted,
- Then waited to drain battery and shut-down itself,
- I connected USB charger to PC and TURN ON THE PHONE !!
- Again waited battery to reach 0 ma,
- Then plugged off and monitored that current widget shows the range btw 3-10 !!
I don't know exactly if it helps but, maybe you should turn on your DHD while carging..

I don't really know. It would be silly for the Android system to display the battery percentage (up there, in the status bar) by reading the batterystats.bin.
My phone's battery level drops somewhat fast, then, when it would reach 30% or so, it doesn't drop as fast. Also, at times, when I reach 10%, 5% or even 1%, I am still able to play an intensive game like Pocket Legends for an extended ammount of time (30 minutes, for example). Pocket Legends is CPU/GPU intensive and it also requires an active Internet connection, so I'd say it's pretty power hungry.
I don't really get the entire purpose of calibration. I have done it and I can't seem to notice any difference.
I'm going to do it again, now, because I switched to a Sense ROM (RunnyDrOiD). I'll monitor the battery with Battery Monitor Pro. When it reaches +0mA, I'll reboot and so forth so forth until it's drawing 0mA, although I doubt I'll resist that much time, so I'll just delete the batterystats.bin after a few reboots, when it reachs 0mA.

If everybody knew the meaning of the word "calibration" then nobody would talk such nonsense.
Calibration improves the accuracy of the percentage shown!
The illusion is that you improve your battery life with it....

As I said... calibrating the battery may fix the "problem" where once you reach 1% / 5% you can use your phone like it still had ~20%.

Hi there people, I didn't find any battery thread similar to what I'm going to say so I'll spam a little bit
I've just found as I was fooling around this: http://www.ebay.com.au/itm/PowerSki...AU_MobilePhoneAccessories&hash=item20c1a1c8ad
It suppose to be a silicon case with a battery build in(1500mah ..not bad), I don't know the dimensions but I just someone might think it as a solution to our 1230mah small battery(with this you have a total of 1730mah which is plenty)
P.S. To mods.. feel free to delete my post, I just wanted to inform the people about a solution that might be handy

first of all try a battery calibration program like this: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
maybe it is a calibration problem.
as far as i know batter stats are not erased with a factory reset
then try an app like this :https://play.google.com/store/apps/details?id=ccc71.bmw&hl=en
it should tell you the battery capacity and see if everything is working as it should.
good luck! i hope that will solve your problems, or at least find out what your problem is!
P.S. if it is an app related problem, or wakelock related you can find it with betterbattery stats.

That battery calibration app is a placebo. The batterystats.bin file doesn't do anything to change the microcontroller inside the battery pack itself.

Allow the phone to discharge fully until it turns itself off, by normal use and not using a battery draining app (or a benchmark). Then charge slowly and continuously until full, without making the battery hot, eg. by USB port on computer.
If you discharge too quickly you risk getting the red light of doom.

Last few percent takes longer to charge, I think this is by design. Mine behaves the same way.
