A few of our customers have reported issues with their iPhone 6s phones having unexpected shutdowns and other power issues. Luckily, Apple recently released a replacement program, and if you’ve experienced issues with this, you can check to see if your model is eligible for a replacement. The news website 9to5mac.com has a good article with detailed instructions on how to check if your phone is eligible (https://9to5mac.com/2016/11/28/apple-how-to-check-iphone-6s-battery-replacement-serial-number/), or go directly to Apple’s website and begin an online chat with one of their representatives (https://getsupport.apple.com/?caller=psp&PRKEYS=PL133) to start the replacement process.
If your phone isn’t covered by the warranty or this replacement program and you’re still having issues with the power or battery, there are a few things you can check out. First of all, try seeing if you can close some of the apps you have open- it’s possible one of them isn’t acting right and is either draining your battery or causing problems. On the home screen, quickly “double tap” on the home button twice to view every program you have open, and try deleting the apps you don’t need open right now by swiping up. If that still doesn’t work, try restarting the phone by holding down the power button for 3-4 seconds. You can also see which specific apps are causing your battery drain by going to Settings –> Battery, and it will show you which apps have caused the most battery drain. Lastly, you can check out one of the many free “battery saving” apps in the app store. Battery Saver (https://itunes.apple.com/us/app/battery-saver-manage-battery/id999500679?mt=8) can show you some more details about your battery performance if you’re continuing to have issues. If all else fails, make sure you have a portable battery charger available in case you run into issues!
