I have to be honest, I went to the trouble of changing my battery using an ifixit kit but the new battery had no better life than the one I was replacing. I've been through so many guides trying to figure out if there is some setting I've got it on that drains battery life but I can't find anything. Meanwhile, I didn't have a warranty to invalidate, so to speak, but my only chance to rescue my phone now is to take a gamble that my insurance providers will be able to fix it. Now I'm worried that I'll have invalidated that policy. I LOVE the idea of ifixit's battery replacement kit as much as I'd love to stick it to Crapple but I'm afraid for me, this kit wasn't worth the money or the hassle. But on a side note, I'd like to urge anyone read this to avoid Crapple products. They're designed to fail so that you just buy more of their products but I will absolutely not be giving them any more of my money. Thanks anyway ifixit.
