Hello everyone. My samsung is a bit sick now (lol). Basiclly the problem is in the battery indicator . Using battery calibration app i figured out that it shows very wrong percentage. On full charge i have about 4200 mV. But then the % keeps going down very fast , and at 20% i still have 3500 mV left. So what can I do to fix this ? Btw Im guessing this was caused by me , cause i flash roms pretty much everyday lol

All is related by your use. If you are flashing a lot, I suppose that the screen is 99% ON and this drains a lot the battery.
The Li-Ion battery do their best when they are at about 75-80% of charge (they actually don't need to be charged at 100% @ 4200 mV every time); this is why you get fast discharge after pull off the charger and have little discharge after.
You should also know that these battery cannot be discharged under a threshold, otherwise you can damage permanently the battery, this is why at 3500 mV the system tells you to connect your charger before the device turn itself off to protect the battery.
for more information about battery you can visit: http://batteryuniversity.com/
I used an app called battery calibration. It basically resets the battery stats after you have flashed a new rom and it works great for me. Charge up the device. Run the app. Then let the batter discharge fully before charging again.

Actualy when you have 3500 mv on most devices you would have 0% of battery..most devices opetates between 3700-4200 where 4200 is full battery and 3700 is empty.

battery stats wiping doesent do anything with battery life.
also im getting about 4 hours of usage out of my battery ( i mean screen on time). is that good?

Lol I think it should be more than that, because the 4.0 with screen on (all the time) gets 4 hours too.

I recently bought this battery: http://amzn.com/B002MRA8FQ
However, it doesn't seem to last longer at all compared to the stock battery. I thought that maybe I needed to drain it fully and then recharge it the whole way before it would work properly, but I noticed that it was reporting 1% life left for a good hour or so before I gave up trying to drain it. Is it possible that the battery life isn't being detected properly since its not the stock battery or is there something else going on that it lasts exactly as long as the stock battery?
as i read the article, it doesnt apear to be an original LG battery...did u ever thought that batteries are not all about XXXXmAh? More is not always better
Think of cars... an american car(ex Ford Mustang) has an 4000cm3 engine producing 200Hp . Subaru has an 2400cm3 engine producing 300hp
But i could be wrong
Cheers !
You can try wiping battery stats
How do I go about wiping the battery stats? I'm using the stock rom BTW
You need a custom recovery (root your phone first)
You can gohere if you are unfamiliar with these terms
You can do it without custom recovery if you are rooted. Use either Battery Calibration app or Root Toolbox app. Both available in the market.

Charge your battery to full, 100%, then wipe battery stats, and allow your battery to DIE. Then your problem should be fixed. i went through the same problem, i bought a special battery with better battery life and my Optimus t, running at 806/480 on smartass governor can run for about 4 days without dying, and thats with constant use

mah DOES matter!
Battery life is dictated by the mah and how you use your phone. It sounds like the battery you received is defective which happens when you buy them from sites like ebay or amazon. Is there a return policy or warranty on the battery? You should definitely get more talk time and standby time with an extended battery.
It is a common misconception that you have to let the battery drain all the way. These are li-ion batteries which prefer a shallow discharge. Meaning, they prefer to be charged when they are at about 25% capacity.
Best of luck to you!

So true. The closer they remain to fully charged the longer they last.
So I have just flashed the CM7 ICS Themed BETA, wiping everything.
I then charged to 100 percent, and used Battery Calibration app.
I have just setup some apps, and I have lost 10% battery life in 40 minutes
Display is using 85% battery life apparently.
Please help?
It can take up to a week to fully calibrate the battery. Since the battery doesn't have memory the phone has to get a feel for how much juice it actually has. Try it for a few days running the battery down and then charging it to full without unplugging. If that doesn't work you might want to try charging all the way then reflashing and immediately do a calibration.

Yeah, I'd calibrate the battery - wouldn't hurt.
Ideally always flash on a 100 % full battery to avoid problems like yours..

Cheers guys I've taken this all on board.
I'm on 13hrs on battery, its showing 16pc. Battery calibration app shows 3609mv however. This doesn't seem right to me. Am I correct in assuming the phones battery power is the mv listed and no battery is more like 100mv??
Could anyone explain the 'mv' term to me?
Is 0mv when it powers down? Is this indicative of power?
Thanks.
Lithium ion batteries never fully discharge. If they did the battery would not recharge again.
Sent from my MB860 using xda premium
mv referers to mV, as in Milivolt. Most li-ion batteries are rated at 3.7V or 3700mV. A nominal full charge should be around 4.2V or 4200mV.

That's 35 minutes of active use. 10% isn't outside the realm of the possible.
I usually can go a full day on 60% battery, but this morning Facebook, the interwebs and text messaging put me from 100% to 77% in the course of 30 minutes. Draining 10% in 45 minutes does not seem out of the realm of possibility
I get mine to last around 20-26 hrs on a single charge, of course depending on use. but i hardly leave the house and dont use it a whole lot. One thing to make sure of is setting up profiles on SetCPU and/or undervolting. i just posted my setup on another thread. http://forum.xda-developers.com/showpost.php?p=20284361&postcount=28
so after you clicked the battery calibration button and it said calibration successful, you're wondering why the battery is dropping so fast under use right away?
Easy answer my friend, when you first use the battery calibration app, the first cycle (when phone is being used) will always drain a lot faster than the 2nd and 3rd time around.
The battery calibration app, wipes the battery stats, and makes a new one, however that does take at least 1 - 2 times of a full charge/discharge of the battery. There is a battery tread in the atrix general forum i believe for cailbration steps, etc to go about successfully doing a complete calibration when flashing from rom to rom.
Hope this helped
Hmm, maybe I am just upset that I have to charge every night.
Coming from a BlackBerry 9780 I could go 2 days with semi-heavy use.
I am now using the official Motorola cable, and only charging from very low to full.
Thank you for the advice.

Try getting one of these:

1900mah extended battery
Problem Solved.
Bluetooth radio was killing my battery. WiFi is fine leaving it on as it disables in stand by, but bluetooth was absolutely draining everything.
thanks for the update
I agree, 10% loss in 40 minutes of active usage is not bad. If the OP had better battery life before he flashed to new ICS themed CM7 beta rom, maybe the new rom is to blame??? I'd OC/UV, possibly with the latest faux123 kernel.

My XPERIA X10i charges up to 100%, then stops charging until the battery drops below ~93% and then starts charging again.
So depending on when I unplug the charger, I may or may not have a 100% charged battery.
Clearing the battery stats and checking again can't hurt.
Just give it a good charge for up to 12hours
If you disconnect the charger and then reconnect it again, does it start charging again from 90% upwards?
It won't charge the device when the battery is indicated to be 100% charged, so there still could be a problem.
Good chance to buy a 1800mAh Mugen Power battery. Mine gets from 1 to 3 days depending on use and has a heavily under-clocked CPU over night or when not in use. Seems to spend over half it's time in deep sleep.
Hi there, wiping battery stats doesnt actually do anything in relation to battery level. It was a myth and all placebo effect.
I remember your screen name from a while back when I still had my x10, so it could be the battery itself starting to die.
You could get an extended battery (or just a new stock battery). I had the 3300mah and it was awesome.

most people here are changing ROMs...and most of the time people say that some ROMS are a big battery drainer..
some move to other ROMs because they noticed that the battery performance of the ROM they are using is changing..
this happens because all the records on the way we charge are saved on the battery stats..sometimes our battery meter says the wrong information. that is why we have to calibrate our battery...we usually do this by going to CWM and wipe battery stats..
but are we really doing it the right way?
here is my guide to do this in the proper way:
i know some of you are using battery calibration from them the market, but all it does is just delete battery_stats.bin from system..But the truth is, the system is still writing the old battery stats if it's erased online...So the only solution is to delete it through recovery...
this is what you need to do:
1.Install Battery Monitor Widget from Market for Monitoring
2.Charge your phone to 100%
3.When done, restart your phone, but go to CWM recovery
4.Go to advanced -> Delete Battery Stats
5.Reboot, you should get battery about 90-100% (depending how much margin has been wrongly calculated)
6.Open Battery Monitor Widget to monitor the voltages. the maximum voltage is 4200mV for Li-Poly battery. Try to reach that value before disconnecting the charger.
7.Before the voltage graph getting dropped, Disconnect the charger immediately. for me it is stopped at max 4190. your mileage may vary.
8.You're done, your battery is calibrated..
kind regards,
baiclark

For sudden drops to 0% Sony Service recommends that you charge the phone to 100%, remove the usb cable and the battery for at least 10 minutes. Return the battery to your device, turn the power back on and put your phone back on the usb charger until it hits 100%.

As you are saying that your mobile seems "hot"
First you need to confirm that its charger/device issue or only with battery.
First do battery calibration with this method: (In this method you need custom recovery for your device

IMPORTANT: You can skip this step>> "Wait 20 min after you are sure it is 100% (phone should stay plugged in)" - As i dont know much about LG devices and their batteries
Now some advice from me-
If you can cover it >>> Never charge battery again and again before 15 or 20%
Always charge your battery to 100% at once and use your device till 15% or less than 15% and then again charge it full and so on...
This will make your battery backup good as well for battery life

According to the Battery Doctor app, you shouldn't leave your phone on charge for more than 9-10 hours(MAX), otherwise it WILL harm your battery.
You should try hibernating some of those apps with Greenify.

Use better battery stat (check play store) or similar app to track draining application.
