(Help) Problem with Android OS (kernel)

[linuxgator]

It does not work. Android OS is still draining battery very much.
I'm using Scud Battery (1800), i don't have original battery.
Can my battery be the cause?

The battery could very well be the problem. I suggest getting a Motorola battery, like the BP6X. If that doesn't work, it is most likely a hardware issue with your phone, and there's not much you can do about that except get a new phone.
