No its not an issue it is obvious that if u run heavy games, battery consumption will be more and temp will automatically increase.
This is happening to me also, and it's not just a heavy load issue. I don't have this problem with stock rom. I also use FreeX10 beta4. I monitored cpu usage and there didn't seem anything unusual, however monitoring the mv of the battery is noticed it will sometimes be around 4153mv while othertimes 31200mv not sure what's causing the higher mv's though

[Q] Problem with battery and speaker

Hello,
I have Samsung Galaxy S3, rooted, running on CyanogenMod 11 M12 Snapshot (cm-11-20141115-SNAPSHOT-M12-i9300) and i have two main problems.
1) Firstly, I have a problem with battery. My battery is charging and discharging very fast. I had this problem also on TouchWiz, but I thought this was a problem with system. Now my phone is charging really quickly (40% in 15 min) and discharging in about 4 h of using. I tried calibrating the battery by charging it to 100%, then I restarted my phone to check is it alright and it was, so i calibrated it with a Battery Calibration app from Google Play. Then I used Fast Discharge (as recommended) and I checked to use processor. After 5% of battery (95%) my phones screen turned white, there were weird sounds (like old TV without signal) and then it restarted. Battery was 25%. Now I'm charging it again, unfortunately it's again charging so quick.
Is it a problem with my phone or battery? My phone still on warranty, so I can make full fix from this forum and give it to Samsung.
2) I also have a problem with speaker. When using my phone I can hear weird sounds from it (like above - like old TV without signal). What to do? Can You help me?
Please, help me

Check if you have a swollen battery
try a replacement battery, the weird sounds and screen issues could be from the battery not supplying enough current/voltage to the phone, hence also an issue why it cant calibrate well

[Q] Battery Issue on Lollipop Roms

Hii everyone
I've got some really weird Battery Issues on different Lollipop Roms (CM12, ResurrectionRemix 5.3.5-5.3.7, Beanstalk and SlimLP).
The problem is, as soon as i restart the phone the battery percentage drops from 50% to 13% for no reason.
If i charge the phone later suddendly the loose percentage are back, but the phone consumption more "battery" so it's sooner at 0% as normal.
Does anybody else faceing this problem? Or whats the solution?
(Tried several times to calibrate the battery, and it's a new one ca. 6 months old)
Regards Kun1

I've had these problems when I first bought my phone used off eBay. Phone battery was very erratic. After a reboot battery would be less than half or nearly 0 even with 80%+ battery. Or would shut down with 5% left. Or drain battery a lot quicker than normal.
Soon as I bought a new battery my problems vanished. My battery would stay solid no matter how many times I flashed a new ROM or rebooted. BUT after 3 months these drops have started to happen again with reboots. Not always like before, but they're happening.
I think it's down to battery conditioning. The way you charge and discharge your battery. There are set ways to charge a phone to maintain battery health.
How does your battery react without rebooting from a full change to shut down? You shouldn't need to reboot a phone with a good stable ROM once you've set it up the way you like it. Also calibrating you battery or wiping your fuel gauge meter to often isn't good practice as android and your phone will do calibrating itself after some time and needs the information that these starts provide.
Battery jumps seem to happen with a lot of S2 users. Maybe a flaw in the design of phone. But good battery practices are important, things like not leaving your phone charging overnight. Batteries don't like being left on charge when they are full. There's more info out there on XDA that I can't remember myself as I am guilty of bad battery practices as I use my phone all the time and don't have time to full charge cycle.
Yes same problem
Battery drains really fast when restarting
Any fix for this?
I am hiving battery problems too. Battery is dropping % like it leaking or sth. Last time my phone rebooted due to full ram and it dropped from 50% to 12%. I left it like that. After some time battery re-charged itself from 12 to 23 % ! Phone was lying on the sofa without connected charger ! Should i clen fuel guage chip or my battery is EOL ?

you have to reboot for example if you install xposed and new modules i've calibrated the battery just 3 times i think this isnt too much?
and i understand the problem with charging overnight but there's no other solution for me :/

Hello, your situation is much more serious than mine. I reinstalled the original ROM jelly beam 4.1.2 because I can not charge the smartphone every 5 hours.

...of course, now my battery lasts 15-18 hours
When it developed a ROM that overcomes these problems of battery life, I'll be happy to try it.

ps: I may have missed something
Forgot to say, if you want to avoid battery drops when rebooting make sure you plug your phone into charge before rebooting. Thus should stop battery dropping afterwards.

The battery often drops when the phone hangs at work and reboot from itself so i have no chance to plug it in.
I have same problem, battery drain too fast & after reboot same time battery level is "falling" at one moment twice. At first, I think it's a battery problem, but battery work fine at CM12 mod, and have problem at SLIMLP 5.1.1 mod. When battery "falling" it's not heating, which means no real discharge.
Hello friends I just purchased a new battery this is 3.7V battery
But the old Samsung stock battery that comes with the phone is 4.2V is this ok or this is necessary to need battery is 4.2V im still useing jellybean stock os 4.1.2 but im a custom Rom Flashaholic please guide me should I need a same battery volt so I return it and find another I purchased it from amazon estore thanks for replying

Incorrect battery percentage

Ever since I got this device I've had issues with it being unable to correctly detect the battery level. Very often the phone discharges completely and shuts down, and upon a restart it shows 20% battery left.
I've tried calibrating the battery, but I'm either doing it wrong or it's not working... What else can be done to fix this discrepancy?

From my experience, if you use ROM based on Android 6.0 this can happen and in this case you must recalibrate the battery by draining it completely by few restarts and then charging it to 100% and leaving it on charger for 1h more. If you use 5.x Android this behavior is a sign of a battery loosing it's capacity. In which case you need new battery.

Try to use slow charging couple times, I mean 500ma charger or charge via pc slot.

s9+ sudden battery percentage drops

Hi Guys,
Have a problem with my battery. Very recently my phones shows different percentage after I restart the device at low battery. From 18 to 3%. Please see attached battery screenshot. The battery actually corresponds to the lower percentage.
