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°

Then it just might be ur battery.. if u need a good replacement battery, i suggest to order a PolarCell 1800 mAh battery from ebay for 12.90 euros including shipping, took about a week till it dropped in my mailbox

Been hours of charging but the batt wont FULLY CHARGE..Have no idea what in the world is going on with my battery..

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

Btw, dont just go out and buy any battery on ebay, theres plenty of fake ones e.g "4000 mAh" battery could really be a 1500 mAh one..
I cant recommend u a good over 1800 mAh batteries since ive never used one myself.. but ive read that Momax and Mugen batteries are good.

Strange battery drops and screen flicker

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

Thanks for the replies
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.

I am having a similar issue, screen starts flickering incessantly and suddenly battery drops to 2-3% and phones restarts etc. My battery does revolve a little bit, but am unsure if that's normal or not?

Guyz,
I have exact same issue battery drops to 1% suddenly... I have posted a dedicated thread.

[Q] Dead Battery?

I'm pretty sure my stock battery has died after just over a year of usage. However I just wanted to check with you guys whether it's actually flat or if my phone is faulty. The battery will last about a day with minimum usage, but if I turn on wifi or data it will literally die in a matter of minutes? This is the same with every rom and I wipe battery stats. So would buying a new battery solve the problem?

Is the shape of your battery regular??
If not, change your battery not rom.
Note:due to overcharging, shape of battery may change, happened with me.
Minimum usage would drain battery so fast to 0%.

Sorry, shape of my battery? What do you mean by that?

Your battery has been heavily used. It's life is over. These are the symptoms of a nearly-dying battery. When you replace with a new battery your phone will function like normal again.

U can test the phone if is he draining power too much whitout buying a new Sga battery. If you can find some battery like Nokia bl-5c(i use it sommetimes) or some battery similar pins (+//-) to fit it in and try it on.
Test old sga battery.
Try to charge your old Sga baterry in a univerzal charger,do not worry abouth overcharging beacuse it got to protect it.

[Q] Battery almost empty after rebooting?

So, I bought a Galaxy S too. Nice phone. Awesome display. Delightful user experience. Now, few days later, after rebooting my phone, battery level drops from like 90% to just 10%, and restores to the original level after some time. What should I do?

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%?

If ur on a coustom rom..this issue will be there in beta versions of the rom!
Also which rom u using?

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)?

what i presume is that your battery hasnt been recalibearated.. it might be a kernel issue too..

Okay. What would be the best way to do the recalibration if it really is the culprit?

Might be a faulty battery. Check if it's swollen or anything, and try replacing it if you can get a spare.

Dev, I am facing problem after buying a used Galaxy i9000 .
1.I charged my battery fully [100%] , then using after 5/6hr when battery goes down to 34%-35% , the Cell phone suddenly got shut down , When I plug it in , then it says battery was empty . Then I have to charge it again .
2.When battery is 66%-67% , I tun off my phone and started after 5min , I saw it's only 17% !!!
What is the remedy/ solution for this problem .
[Don't say to change ROM/kernel/ clean delvik cache , I have already done them]
Do this problem will be solved by Changing battery ?

Yes, as Knuckle said you will need a new battery perhaps the 1800 MAh.
Hope i helped

Is there any battery on eBay you guys would recommend (free shipping, battery price up to $10 if possible)?

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!

Battery on my galaxy s3lte sucks

I recently bought my s3 new and i'm disappointed in the batterylife.
Yesterday I fully charged my fone before i went to work and put it unused in my pocket and by break time more then 68% of my battery was gone i had only 32% left of battery life.
In total my fone used up to 90% off batterylife without being used. Anyone any ideas???
