Hello all!
I am new to the forum so I hope make it without any errors.
I bought the Optimus 2x cellphone last week whith the hope of getting the good one (the one without freezes and black screens) fortunately the cell worked very nicely. I updated to gingerbread and I feel it very good. But I have the good known problem of battery consumption.
Now I have a battery related question. After the update I charged the phone and get the battery indicator stuck at 100% I rooted the phone, installed Battery Calibration and calibrated the phone (left the battery to reach 0% then fully charged to 100% hit calibrate and left the telephone fully discharge again)
The issue is that when the thelephone was at 100% the voltage indicator of the battery calibration was in 4100 mV and here comes the weird thing. When reached 0% the voltage indicator was saying 2000mV.
My question is if this values are right. Someone with good battery duration and the Battery calibration installed could tell me the correct values? I thought that the phone shut down when battery was down to 0 mV but maybe the problem is that my battery is just using "half" battery.
Sorry for my english. I am not native english speaker.
Any help will be highly appreciated.
Thanks
That is voltage, 3300mv = 3.3 volts.
Fully charged the battery would be at 4180mv, fully discharged is around 3200mv usually, or a bit higher.
The phone shuts off when the battery gets below the usable range, which I believe is slightly above 3000mv.
So yes a range of 3.3 to 4.2 volts is perfectly normal for a 3.7v battery.

Hi! Thanks for your reply. So I think I should get used to it. My battery doesnt last more than 12 hours of my regular use. A some internet browsing and some messaging. No music, videos, or games.
Someone recommends the extended batteries of 3500 mAh for this phone? That will make the phone last more time?
Thanks in advance!

Hi Reaper511989, I have bought an extended battery from HERE. It is fatter, but not ugly. And the battery lasts a lot longer. I use it when I'm travelling. I have no idea where in the world you are, but the battery was from a company in the UK.
Have fun. Anil
Huge Battery drain on DjangoManouche/Guestekrnl
Hi,
I was on CM7 kang of temasek and I decided to flash a stockbased rom.
Now I'm on :
DjangoManouche 1.2 rom
Guestekrnl V1.6.1
BB V20Q with ril
I am using Go launcher which comes with the rom
The battery drain is incredibly huge, 8 hours tops with very little use
Anybody some ideas ?
your lucky. i get 6. if im playing 3 albums of mp3's during work. nothing on. just 2g.
imagine if i turned on gps,wireless,bt 3g/4g ahhhh . (cant use fone how its sposed to be used) have ot turn it DOWN a notch. its to HUNGRY on juice. seriously lookin @ one of those MUGEN batteries.
6 hours is just wrong... in the most intense usage you should get 2 hours of screen ON time.. Wifi with 2g on trolling forums with browser/tapatalk should be 4 hrs.

6hours listening to music is pretty normal. If you want longer battery live, stop using the device.

Well in that case you might wanna repair your device since you seem to have the same issue with all roms. That should not be the case that it uses the same amount of battery without using it, especially if no app is loading the cpu....
Sent from my HTC Wildfire using XDA
well actually. cm7 i got about 5-6 hours batt life, cm9 i got no more than 8, GB (stock rom) can usually go from 5-8 hours. but with no bugs. so i am back on GB.
so i dont think device is broken/dodgy since the batt life fluctuates a little. depending on the rom.
my main issue is, ive been reading about ppl using froyo and going to GB and having mass battery drain. now im thinking about going to froyo.

What apps do you have installed/are you using?
well according to the voltage you either have it over clock or you need to turn the voltage down. and you should check what cpu governer its set too. by the looks of thing it spends most of it time at idle so its problably set to performance, so set it to ondemand
Im facing this when i connected to the wifi.
I over clocked my ram using devil kernel.. governor was on lulzactive
i changed it to ondemand
Now its normal (no over clocked anything) but still wen i use hostpot it goes to 45°

A fully charged battery is around 4200mV i actually get that same amount when fully charged(4196mV) just hit the calibration button and use ur phone normally til 1-10% and charge again and see if it goes up to 100% if it doesnt, i think u just have to live with it.. i had that same problem some months back and just lived with it cause it didnt really bother me. Nowadays it charges to 100%, i recon i didnt do anything special to make it work so maybe urs will start to work with time
Oh..i see,i make a research thru net and found out the battery power for normal user would be 1500 mah and the other hand for advance user they would get a 3500 mah batt power.So should i choose to change it?Usually i do work with my phone so it is botherin me tho.I charge my phone for atleast 4 hours to see how the power would drain the batt without having a wifi/bt and some other bg process,I was shock when after i plug out the charger my batt drain 1% after 1% within a second!How fast is that??!My Galaxy W didn't face the same tho..This is some kinda magic or what?!..It is so irritating me..

Yeah, i use my mobile data on my laptop and the battery drains fast with wifi hotspot on, i always have it plugged in a charger when using it as the network for my laptop otherwise the battery drain is just crazy.. u could buy a 3500mAh battery but ur phone will turn into a hideous brick! cause the battery is so big, thats why i bought the PolarCell battery , its the same size than stock but 300mAh more battery charge. But if u use ur phone alot and ur not satisfied on the juice u get out of a smaller battery , i think the 3500mAh is the way to go
http://ecx.images-amazon.com/images/I/51DFBIUCaxL._SL500_AA300_.jpg
As u can see, u will need a new back cover(that usually comes with the battery 3500mAh) since the batteries physical size is double the size of a stock one

Hope this helps :thumbup:
I had been using Cassies Xtralite rom V8 along with Hydracore 4.3 Std for weeks and everything was fine. One day the phone restarted on its own and the battery dropped from 61% to 1% just after it restarted. Then the screen started flickering too and the phone shut down on its own. This was strange because I had just charged the phone to 100% 2 hours before that and it didn't make sense. Therefore, I charged it to full while switched off and tried again. The battery drained to around 80% quite fast and then after trying to enter recovery to clear the Dalvik cache the battery went down to 5% when the phone restarted. This repeated for a couple of days until I had to do a Full Wipe and flash the rom and kernel again. However, the battery drain and sudden battery drop after restart still remain.
I read about a fuel gauge and tried to reset it by taking the battery out for a couple of minutes after charging to 100% while switched off but that didn't help either.
Does anyone have any answers to this?
Thanks
Charge your phone to 100% and clear the battery stats in cwm
It doesnt improve battery life but improves the accuracy of the displayed battery percentage
Or try changing the rom and see if the problem still exists
some roms appear to be experimenting with battry percentage based on usage. Try another rom.
Ultimately I had to go back to gb, with partition and load bootloader and stay clear of the rom in question to fix my stuff. I dare not go back again because of this issue.
I think I had to do this cause the various roms messed with special partitions, which arent wiped or formatted properly throught cwm. Migrating between different roms didnt fix it for me. wtf.
all at own risk
edit went back and had issues again. Used above approach and it didn't work anymore. It sucks.

Thank you for your replies. I tried charging to 100% and recalibrating or clearing batt stats but it did't help much.
Actually yesterday my phone would not boot and stuck to the bootloader. I had to do a factory reset in CWM to load again but as soon as it did the phone worked for 1-2 hrs and then reached around 70% batt fast and the screen flickered and turned off on its own. Uppn restarting batt was at 5%
Tried restoring a nandroid from mid September and things are slightly better. As soon as it starts the flickering I plug it on the AC and it doesn't die, but that's not always possible. It might have something to do with the batt voltages. I had flashed a Hydracore OC version and it might have messed things up. When charging the voltage goes over 4200mV.

Hi,the very simple methode for your problem is........buy a new battery and insert it in your phone then start it and problem solved !
Very easy don't you think ?
Btw,repeatitly flash rom,kernel,or all side stuff with flashtool or like that and use your phone with high frequency kill your battery very fast !
So,
the first symptom of a dead battery is autoreboot and quick down level.
Don't try to use battery test in factory with custom rom because 80% they not support it
In this case,you have always wrong indications in test mode (batteryHealt=good/100)even if your battery is dead !
Trust me and good luck
Oh and,stay away from chinese battery with high voltage and good price !
Prefer Choose stock or mugen power
Ciao

In fact the battery appears to be the problem indeed. I took it out and placed it on a flat table and it would spin with ease. It is bulged quite a bit. Now looking to buy the original 2500 mAh battery by Samsung and the 2700 mAh battery by Anker to have a spare

If your battery is bulged then it's a dud and won't retain charge, plus you run the risk of it bursting which will kill the phone outright.

Hi,
Hey i am using my note for a year now, and my phones battery got swelled, with some discussion on xda i was adviced to replace my battery which i did with another original samsungs battery. Now this new battery is charging and discharging fine, and is giving me an on screen time of 5 hours with constant messaging and music and some browsing, the issue that i am having is of battery indication and screen flickering.
First the screen flickering issue, whenever i am below 20 % my screen starts to flicker and it keeps on flickering till the phone dies, sometimes even at 15%. Then when i tried to charge it, it charges from 0.
At times when i partially charge my phone, say i am on 50% and then when i unplug my phone at 60%, it then shows 75% indication but then the flickering starts at 30% and phone dies at 26%.
The battery is giving average time so i think its not a battery issue or maybe it is.
But then i mostly found it a battery indication issue, i read multiple threads and even wiped my battery status. but the issue is the same.
may be give it a few charging cycles.. charge it from 0 to 100 with phone off.. till it says completely charged.. then check the performance..

Well yes its from samsungs outlet, dated and stamped.. otherwise the battery indicators and every other stat is good. On full charge it has 4.320 V. Discharging equally to 2.8 V. But indications is not going according to the drain and flickering at low %.

I am having a similar issue where my screen will flicker for a minute and then immediately turn off and charge from 0%. I was wondering if it could be a kernel issue as my battery is the stock battery and has never had problems before (I am on XXLSC). To me it looks like the battery is not getting enough power (hence the flickering) and then turns off. Sometimes if I turn off my phone as soon as it starts to flicker and I wait 10-15 minutes I can turn it back on no problem, other times it will just die. I have tried clearing battery stats, and was going to try my spare battery but apparently that swelled in storage.
Good luck in figuring it out! I will report back if I find anything new.

4320volt, interesting, I think its faulty, its off about 120 volts. If it depletes at a higher voltage, it looks like something is astray with the meter/level indication or battery

Sorry for the confusion it actually was 4320 mV or 4.320 v when full charged.
Let me post some screen shots. The overall on screen time is around 5 hours. So the battery is giving a good timming.

Not enough information. Are you rooted? Are you on a custom ROM or kernel? Have you tried running the battery completely dead until the phone shuts off, then charge it all the way to 100%?

Sorry. Yes, it's rooted. Stock XXJVU, Semaphore kernel 2.5.0b (been using CF-Root and stock kernels before that, but there were no differences in battery level readings after reboot). Nope. How many 0-100% cycles would be necessary for it to do the trick (or fail)?

I thought that someone bought such stuff on eBay and could suggest me some reliable seller(s) so that I don't buy some fake garbage labeled as Anker that will blow up in my pocket. Nevermind.
Okay, in order to not experience bad battery life again, what exactly should I do once my battery arrives? Wipe battery stats, few 0-100% cycles, later just make sure battery never goes below, say, 25%, and I should be fine? Please correct me if I'm wrong.
Yeah, pretty much what you just said. Wiping the battery stats is a bit pointless but do it if it makes you feel good
Polarcell or Anker are the ones to get. There aren't any fakes of those that I've heard of. All the fakes I've seen claim silly capacities.

Is your Galaxy overclocked?
I mean, consider lowering your CPU clock as it seemingly stopped sudden blackouts on my Galaxy.
EDIT: Nope, it didn't.
I had same problem. Bulged battery. I bought a new battery and it fixed the problem
You need a new one!
