today when i woke up morning, my 5800 suddenly switched off and unable to turn on it back. so i decided to charge it and turn on it and is work!!
but the thing is, last nite before i went to bed, i fully charge my phone.

the question here is: where the battery leak to?
and i just bought my 5800 2 weeks ago, considered is still new.

guys, any idea?

Lol... Instead of waiting for the whole night without an answer... I'll try to give my best opinion. Are you sure you really charged your phone last night?    Or maybe you didnt put in the jack properly.. If this happened another time, maybe it is the battery problem.

most of the newbie have this problems... and 90% of the time its their own problems not the phone...
my friend and bro also complains this...
upon checking their phone.... i found tat they left tonnes of unclosed apps (especially the games) in the background...
somemore some even left the light sensor and ringtone maxout, blutooth always on, wlan scanning always on ....

try close off all apps first and try again... if problem persist... go to NCC for replacement...

seem something wrong. why don't you sent back claim warranty?

Nokia Care Centre / Nokia Customer Care does not acquire receipts .. receipts are just for u liase with phone shops .. bring ure warranty card (if have) if not just bring ure phone enuf ..
