wanna ask u guys whether i can claim for warranty

previously i replaced mine under digi cause of home button issue

but now i find that my battery seems rather weak ...

if i leave it at idle without any apps running in background ... i go sleep at night from 12 till 6am ... the batt will run down about 20% as in ... from 80 become 60% overnight ..

previously before my replacement it doesnt really come down so fast ... is this normal?

would like to add this

Q: I have album artwork for my songs but when the song is playing and i go to sleep mode and 'un-sleep' the artwork doesn't show on the lock screen. Once unlocked, album artwork will only show.

A: Do a soft reset on your phone. It should show after that. Soft reset = power button + home button.

It's called soft reset right?
