So last week I sent my 7 in for a screen repair. Since it returned to me, after setting everything back up, I've noticed a significant increase in my battery life. I've been attributing this to me setting it up as a new iPhone (iCloud backup kept taking too long) but I'm seeing about twice as long of battery life as I was. You guys think it's possible Apple is secretly replacing older phones' batteries when they're sent in for unrelated issues? Either way I'm not complaining. Screen is good as new, and with the better battery life it really feels like I have a brand new phone. Anyone else on here have a similar experience?
