CPU Spy+ to check CPU usage.
Wakelock Detector and BetterBatteryStats to check what exactly is possibly using the CPU and heating up the phone.

*#0228# in dialer for quick temperature check

battery draining issue

I bought a new I9505 for my girlfriend. it seems to have very serious battery draining problem. a standard over night standby, doing nothing, wifi connected, battery would drain 30~50%. I tried many different roms and kenrnels, they all work the same way. I also tried deleting batterystatus information file, still no luck. could anybody tell me what's going on with the i9505?
here are some screendhots of the battery usage.

Nope, can't tell you why. Get better battery stats and figure out what's keeping your phone awake and using the battery.
It'll be an app she has installed. You have to find out which one through process of elimination

Battery charging

Why is my phone (sm-n900) charging itself ? Can anyone explain ? I have stock rootrd rom, please answer this question

It's not charging itself.
The battery is just calibrating. The graph is not an accurate depiction of what is actually happening with the battery, but merely an estimation. Therefore when it feels it's "guessed" wrong it'll change.

To check whether your phone is charging or not, you can use my app Phone INFO ★Samsung★ >> USAGE HISTORY >> Charger Connect Counter and check if this counter increases...
No issues with the phone. Nothing that you should worry about. No need to do battery calibration either, as it is completely normal.
When you use phone actively, it consumes large amount of battery. Phone uses consuming data to show the battery percentage, however when you stop the "heavy usage", phone is then re-configuring itself to show the real battery percentage. Happens on pretty much all devices.
Thank you guys !

Overheat !

Hello guys, I was searching for this answer but I hadn't find any competent one, so I have sm-n900 rooted stock firmware, when I'm surfing internet or playing games, it heats, overheating, im worry about inside parts not to "burn" I tried every solution but no results. Is there any way to avoid overheating ?

Its normal There aren´t any big fan like PC´s.
If there is a big overheat CPU autmatically underclock
Or you should flash custom kernel and undervolt CPU & GPU
Can you show me a tutorual how to indervolt cpu ? I'll flash halaszk kernel

Set -25mV or -50mV CPU & GPU voltage in app or aroma
and last question it's not dangerous for phone yes ?
