My iPhone 3gs Battery Problem

Mein Problem

My iPhone would every now and then just randomly switch off just by itself for no obvious reason at all! It then would not turn on again whatever I would do (hard reset, plus to wall charger, etc). Sometimes, it would become also hot but other times not. The battery percentage would also go mad and indicate 20% and seconds later 90%.

Meine Reparatur

Just ordered the replacement battery from iFixit.com and it delivered directly to my home. Was not a difficult task to replace it following the guides.

Mein Rat

Make sure when you order that you order Battery with Apple Part Number (APN) 616-0433, 616-0434 or 616-035(this is what I got from iFixit). I tried another Battery (616-0428) on my 3Gs. It worked I but could not restore new firmware with it on iTunes.
