Apple Store. Some iPhone 5 batteries are faulty and are covered by Apple.My question has nothing to do with the iPhone 6 but this seems like the most active thread...
My iPhone 5 is having a weird problem. I keep it on my desk at work all day. Every once in a while, the battery will just drain very quickly. Most days I'm at work and I don't touch it much, unless I get a text. By the time I leave work, it's still at 90% or above.
Today, though, it's only 3:30 in the afternoon and my battery is at 28%. It's draining so fast I can almost see the battery meter moving. First I closed all the open apps, which I know isn't supposed to be necessary. Then I turned my phone off and back on again. Neither thing helped. It's still draining.
Like I said this happens like once a month or so. I'm not doing anything different with it than I normally do. Haven't changed any settings. Anyone know what's causing this?
