It hardly last for 5-6 hours on standby.
At first I thought it was jelly bean 4.3 that caused the problem, so I removed 4.3 and installed 4.0.4 but the problem remains.
Then I figured the battery must be problematic so I bought a new one, follow the instructions on how to handle new batteries but still it drains it fast.
It drains it with 4.0.4 and with 4.3.
No apps are running in the backround, it drains it on a fresh installation of the OS.
I really don't know what else to try.
Can any one give some help or pointers?
