  • Fixed wife's dead iPhone
    Verified Purchase

    My wife tried to drown her phone. Wouldn't come on past the apple logo (would boot in emergency restore mode). Got the kit suspecting it was the battery. The provided screwdriver was perfect however you'll still need a phillips 000 for the battery connection inside the phone. Connected battery, charged for around 4 hours, phone is good as new.

  • This battery works like a charm!
    Verified Purchase

    My friend had just replaced her iPhone with a version 5 and two days later needed to download the old iPhone 4 - but somehow the battery completely and utterly failed in those two days - shady... Anyways, I did a quick search online and found that it's quite easy to avoid the *** fee and get a new battery online. Then I saw Overstock sells them! I was quite happy about that. The purchase was easy, as always. The shipping was quick - due on the 12th, came in on the 11th. Then the replacement was a snap. One tiny issue if you don't own a set of jewelers screwdrivers - some iPhone 4 phones use tiny Phillips-head screws and some use the random head that comes with this kit. You should have both on hand for the replacement - even if your external screws are the weird screw-head sold with this set, the internal battery screw will be tiny Phillips. Rest assured the battery will work fine in this set. It's charging quickly as we speak and we've already sync-ed it once.
