Iphone5-ios7I 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.

    I noticed this New year's eve, while taking photos. Was 36% and died. Happened a couple more times at various battery percentages... restored phone from a backup, it happened again so I reset all settings - this has helped. Wondering if i'm wasting my time going to genius bar tomorrow a.m. This never happened until iOS 7.0.4 #

    I am not sure how you charge your phone, I believe it will be a good idea to charge it overnight or at least a 5 hour charge. Btw why not use one of the utility app to monitor the charging, it helps. #

    I've been noticing this recently, too. Granted, I normally begin charging my phone before it hits 20% but recently it shut down on me at 23% left and so I wondered what was up. I tried charging it completely and then running it all the way down. Out of the last 4 to 6 attempts, it made it all the way to 1% a couple of times before shutting down but at other points it would shut down at 9, 10, 13%, etc. I was running it down today and it just shut off at 9%. Oddly, sometimes, if I leave it turned off and wait a few minutes then I can turn it back on - like new and it started back up with 8% left. I have no clue what is going on but I've had the iPhone 5 for a year now and i would think even if the battery had reduced life left that it would have calibrated itself by now. #

    I drain and cycle it religiously. This has only happened since iOS 7.0.4. Apple store set it up as a new phone, no apps, music, etc. since yesterday. It shut off @ 9% this time while taking photos. Previously, I could drain it to 1% before shutdown. Apple, ATT no help re: replacement, other than swap at full retail price (out of warranty). It actually EATS battery worse now, setup as new phone. Grabbed the IPSW 1.3GB installer and restored (locally) again tonight. If iOS7.1 doesn't fix this, it's off to T-Mobile for their promo... We are not alone with this iPhone 5/ iOS 7.0.4 issue either... https://discussions.apple.com/thread/5338609?start=165&tstart=0 PS- Battery checked out fine at Genius bar. iOS 7.0.4 is the culprit... What good would a battery status app do anyway? #
