[Q] Phone randomly shutting off
I'm kinda new to xda so I hope I post in the right section and that my problem isnt very common.
Since I installed Android 4.2-4.3. ROMs I have got a very annoying problem. My Phone is shutting off randomly when it isnt on the recharger cable. I can look on the homescreen but once I start using apps e.g. whatsapp, facebook for like 1-2 Minutes the Phone shuts off. Moreover it maybe could be a battery problem because at the first restart the phones displays 0%-5% battery and when I restart it again with the recharger cable it displays like ~60%.
I tried wiping cache / dalvik cache too, aswell as I tried a "factory reset" in Recovery, which sets my Phone to some strange 4.1.2 Version of Android and I dont know why.
Phone: Samsung Galaxy S Plus (GT-I9001)
ROM: ParandoidAndroid 3.99 | Halo 2.0 (tested CM 10.2 and EHNDROIX III (13.8.6 I think) same problem)
Kernel: K^Kernel 3.4.62 v2.2 OC UV 360MB+ (tested Phenom Kernel v5.0, same problem)
Recovery: CWM & TWRP 220.127.116.11
CPU: 245mhz - 1402mhz (tested 1804mhz tough, same problem)
Voltages: I doesnt touched voltages at all (or the Kernel does?!)
I'm pretty annoyed by this problem and I hope you guys can help me.
