huhu .. cannot help you .. huhu .. local apple also no help ... cuz no iphone parts...batt finish fast fast then turn off no use programs ... if still finish fast, don't use your iphone so much lor...cry see scratch then buy new one no cry liao lor..hoho

even if you are using casing .. a slip from the hand onto the hard ground ..might not save your iphone
yea cosmestically it's flawless .. but can it guarantee nothing jump out of place inside the iphone?
the best is just taking very close care when handling your iphone... but no matter what ... eventually your phone will take a tumble... sooner or later ...
it's the matter when and where ....
