Several users have reported an issue in which iPhone powers off as if it has run out of battery during normal use (texting, browsing the web etc) or while not in use even though the phone is showing more than 5% battery life. If you are having this problem, here is how you can troubleshoot:
1.Although there may be many causes for this problem, we will start with the easy but highly likely one. It may be that your phone’s battery gauge needs to be calibrated. Apple recommends calibrating all your iOS device’s (iPhone, iPad and iPod touch) batteries once a month. If your iPhone powers off while the battery charge indicator is above 1%, do this:
- Connect your device to a power outlet for five minutes. Your phone will restart automatically when there is enough charge.
- Then disconnect your device and do a hard reset of your phone by pressing the home button and the on/off (sleep/wake) buttons together until you see the Apple logo. Then use your phone to drain your battery until it shuts down again. Repeat this process until your iPhone starts shutting itself down at 1 percent battery life. It usually takes one or two tries. Then the next time when your iPhone shuts down due to insufficient charge, plug your device into a power outlet and charge continuously for four hours without using the phone. If this solves your problem, from now on, once a month, completely run down your device then charge the battery to 100%.
2.If the above solution does not fix your problem, you may have a software issue. To check this:
- Update your iOS if there is an update available.
- If updating iOS does not fix the problem, back up your device (iTunes or iCloud), then erase all content and settings and then restore it as a new device. Use your device to see if your problem still exists. If the issue is gone, you should now restore your device from your iTunes or iCloud backup. If this does not help, it may be that your have a hardware problem.
3. If one of the solutions above does not fix your battery problem, it may be that your device’s battery is faulty and needs to be replaced. If your new iPhone is under one year old, your warranty will cover this replacement. If your device is out of warranty, you may have it replaced by Apple for $79.
