I bought this to replace an ebay special battery that I swapped in last year. While the ebay battery extended the useful life of the phone, it has started losing a charge faster. Comparing battery reviews, the iFixit battery was highly regarded so I'm trying it out. I'll know in a year or so if it was better than the ebay special.
Easy replacement, but the screws are so tiny I could barely see them, and I could not tell if they were pentabular or phillips.
Borrowed a locksmith's magnifying glass and light table. Made the work much easier than straining my 40+ yr old eyes.
