I waited one full week before updating my business critical iPhone 5 from iOS 6 to iOS 7. I wanted to read some reviews and hear feedback from friends and family before making the jump “forward”.
While there is much to say about iOS 7 — some good, some not so good — but my biggest disappointment has become the battery life indicator. Under iOS 6 I could run my iPhone 5 to about 3% before I would have any concern that it might shut down on me. Under iOS 7 that same phone will often shutdown with 15% left. This morning I was going to listen to a podcast because I had 23% battery life remaining, but it shut down as soon as I began to play the podcast...
Maybe this is just my phone and what I run in the background but I don't think so. I've talked to other iPhone 5 and iOS 7 owners and most express some displeasure of battery life not being accurate or what it used to be under iOS 6. Apple's discussion forums are also full of questions about iOS 7 battery life indication and drain.
If there is one thing Apple could fix in its next maintenance release it is battery life accuracy. It is unnerving to think I have to keep my phone above 30% in order to ensure it won't die on me when in the middle of an important phone call, text or email. It is annoying as a consumer, but for my business, it's mission critical at times. Apple needs to find the issue/s and issue an update sooner than later.
