[SOLVED]Fake Battery Drain on 3G

---

Hi! For a long time i didn't use the 3G connection but only wifi. Yesterday i made a 3G subscription but i faced this problem: when i enable 3G battery percentage remain constant (Full charge) but in almost 2 minutes of normal usage (internet, mail...) battery percentage immediately drains to 0% and phone shutdowns. At first i thought it was the battery that losed health but when i rebooted my battery was still full and i could've used all my apps in wifi normally without any drain. I tried to upgrade to Cyanogen7 but this didn't solve the problem. I have no over/underclock, undervoltage or similiar stuff. I tried these kernels:

On stock ROM:
-Stock Kernel
-Fugumod 2.4beta3

ON CM7:
-Arakmar G3MOD
-"Stock" CM Kernel

Thanks in advance for help

Sorry for bad english

i think that you must change the battery. when you are in 3G battery has heavy power drain and an old battery can't give normal voltage to the phone and it shutdown. it's like an old ups for pc

Maybe it's the problem with your battery... 0.o

Ok i will buy a new battery, meanwhile i've found a provisional solution by undervolting -100mV all frequencies between 83mHz-600mHz, and now phone shutdown less and while my battery has 100-30% charge i can use 3G without any problems.
