my Samsung S3 gets over 100 degrees when data is on and the battery starts to drain really fast and will drain even if it's plugged in. What do you think is wrong and how can I fix it? Thanks to all who answer.
I have already done everything from power saving to lowering screen brightness etc. Even when the screen is off, the same thing happens as long as data is on! Data is off and the phone cools down and everything is fine. This happens all the time.

So, about two weeks ago my phone started acting kind of strange - in the sense that battery started discharging a lot faster than usual - back then I just kind of shrugged it off as probably a radio/ROM/kernel problem, and kind of forgot about it. Then, it got worse.. to the point where I now get about 3-4 hours of life out of the phone in standby mode, with only WiFi being turned on, CPU underclocked to 729Mhz max. Furthermore, the phone gets really hot after a while of using it.. I tried flashing differnent kernel, different radio and ROM (clean wipe, battery calibration), but nothing helped..
If that helps, SetCPU indicates values around 40°C battery temp.
Do you think it can be battery dying? I have it only for a little more than a year.. if not, any idea what can that be?
Thanks.
My issue is that When I am using the phone, normally on dolphin or else a chan viewer, my phone will just turn off. Like the battery died. My phone would have somewhere between a 70-20% charge. Most the time it is above 50%. I will power the phone on and it will say I have 1-3% charge left then shut off normally after.
If I plug it into a charger after that and boot it up (or pull the battery then on a charger and boot it up) the phone will come up fine and say I have 70-20% left. Just depends on where it was at before it shutdown. I can look at my battery usage when it comes up and you can see it go from say 60% to 2% after reboot, then back to 60% once I get it back up. There will be gaps in the usage.
I am currently on Shooter with the freedom kernal. I was on chop suey. I have not reimaged my rom, but I have reinstalled the kernal. I have tried to calibrate my battery and wiped the battery info.
Also my phone charges really slow now too. It can take 20-30 mins to go 5% at times.
I think I just need a new battery.
I think you're right
I was at about 49% battery life when I rebooted my phone (to try my new Maxroam sim card) and when I started my phone again I was down to 22%?!
I have attached a screenshot to show this? Anyone have any ideas what the problem is? Is this normal. My ROM & Kernel is in my Signature.
I've had the opposite happen, too. Had 40% battery left, rebooted, suddenly it had 60%.
I'm 99% sure it's not an actual change in battery charge. It's probably something related to how it measures battery capacity, and rebooting throws it off. I wouldn't worry too much about it.
This has happened on my Captivate as well as my GNex when it randomly reboots. I have noticed that it usually corrects itself over maybe a 15-20 minute time period. I have no battery charts to prove, but when my captivate would crash and reboot the battery would be much lower than it was before like you described. If you watch, you'll see the percentage go back up without charging. Its just a glitch in the reading when things crash or don't shutdown correctly.

Hi, I've noticed that the phone has fast boot enabled by default,which improves the boot time very much,but I have 2 questions about it:
1) when you shut down the phone, is it completely shutdown like with hibernation on PCs or is it in a sort of standby? I'm asking this because before shutting down the phone battery was on 75 percent left and now, just after the power on it is on 56 percent... I don't know if it is a matter of battery stats not yet calibrated or if battery drains overnight with phone shutdown and fast boot enabled..
2) battery usage stats are not reset upon a phone restart, so I can not see the screen on time related to my second charge, since it continues accounting time since the first boot... Is it again related to fast boot, which does not shut down completely the phone?
Do you leave fast boot enabled? Are there other cons related to it?
This is a very great phone, let's hope firmware 1.28 improves the battery life..

I think it depends on how you use the phone. The only time I turn my phones off is when I want to reset them to clear some software glitch or other, and since that needs a full power off, I disable fast boot. The One X still boots quickly enough without it, considering I don't do it very often.
If I was turning the phone off and back on more frequently, I might leave it enabled. I guess that's down to personal preference and usage patterns.
In terms of what fast boot does, I think it's a low power sleep mode, not full Windows-like hibernation - i.e. there is some slight power drain while the phone is off. In one of the DHD threads recently, someone had significant power drain from a rogue app even while the phone was turned off. When he disabled fast boot, the battery drain went away. This suggested to me that this app was stopping the phone from completely sleeping - but if it had been completely powered down, that wouldn't have happened. I don't know this for a fact, though, it's just a theory based on observations.

I may be in a similar situation, since 15 percent of battery life drain in 8 hours with phone shutdown is definitely too much.. hope firmware 1.28 will help also for this

Definitely too much - mine loses less than that overnight, and the phone shouldn't use more power when it's turned off than when it's on!
As you say, hopefully updates will fix it.
After taking Marshmallow, I am finding my phone just randomly shuts off, like a full off, randomly when the phone is less than 10%.
Sometimes it does a full off at 7%, others at 4%.
It doesnt even say, "Powering down". Its just a blip and black screen.
It is random. It flipped off at 12% the other day. 5% earlier. I've done a full deplete and full charge several times to try and calibrate it, but no luck.
It could be this phone. I need to call and have it replaced tomorrow.

Just to let you know, I don't think it's your phone if you are on Marshmallow. Out of the million phones and software updates I have taken, I have never had a buggier phone than my G4 on Marshmallow! Factory resets, cache clean, research etc... Touch response, knock code, page loading, app loading seems to be much slower and not function near as well as lollipop.
I have also read somewhere about early shutdowns when battery is low.
To say the least I am disappointed in marshmallow on my G4.
Im getting the same thing usually at 4%.
battery life always seems to go 10-20% on every android update I've taken since my galaxy nexus. Its kind of getting annoying.
Im probably going to do a factory reset soon.
2 hours of screen on time is just terrible.
Yea when I first got my G4, I had battery for days. Like 30% at bedtime after playing on it all day. Now its dead at 4pm and I barely use it.
Good to know there is a weird battery bug. Before it would go through a power down screen and gracefully shut down.
