Second Question:I Heard from a friend that its good to drain the battery for the first 2 uses until it reaches 0%.
Your friend is living in the "nickel cadmium" days. Modern "lithium-ion" batteries, otherwise known as Li-ion, don't have a memory and can (and SHOULD) be charged before they run dry.
Fully draining your phone’s battery is never a good idea, because it causes high stress on the battery when it’s time to recharge it. In fact, the experts at Battery University say it’s really best to not let the battery run down below 25 per cent.

Okay thats really helpful ! Thank you a lot! i didn't know about the 25% thing.
When i bought the phone i had the choice to pick between a normal rom and a multilingual rom.
I picked the multilingual rom and they didn't even check it if it was ok..
So the rom was bugged and it was stuck at -2%
i installed the Global version and everything is running smoothly !
