iPhone turns off with 10 percent battery left
Just to clarify the issue we’re dealing with in this guide: Your iPhone turns off with battery left? It may be shutting of at 10 or 15 percent, or even shut off at 20 percent, while the battery life seems to have gotten worse over time. And if you reconnect your iPhone to a charger after losing power, it may display an irrationally high percentage of charge, which couldn’t be possible after such a small period of charging, right? This sounds like you could benefit from one of our three fixes for the “iPhone battery dead?” issue.
1. Check your time and date settings
In one of the support documents Apple explains a possible solution to fixing issues with your iPhone 6s and iPhone 6s Plus battery percentage.
If the battery percentage doesn’t update by itself, you can try going into your “Settings”. Select “General”, then “Date & Time” and verify whether the option titled “Set Automatically” is active. When active, your timezone and the time will be updated automatically according to your location and the battery percentage should update as well.

3. Battery replacement
Last but not least, there is always a possibility of hardware failure. Most of the time this is simply due to the fact that the lifespan of your iPhone battery has reached its end. This means that Apple, a service provider or you will have to replace the battery in the device.
Note: If you have installed iOS 11.3 you can check your battery health to see if the battery in fact needs to be replaced. Learn more about the battery health feature.
Before exchanging any kind of hardware, we recommend checking the software side of things. The easiest way to check whether any of your settings, apps or a part of the operating system is interfering with your battery life, is to fully reset your iPhone.
Restore your iPhone (without a backup)
Open up the “Settings” app, then go to “General” and finally “Reset”. Now tap the button titled “Erase All Content and Settings”. Then follow the assistant to set up your iPhone as a new device, instead of selecting your most recent backup. This will provide you with an opportunity to test the iPhone as a clean slate, so to speak. If your battery issues are gone, you had a software issue. If you still experience the premature shutdown issue, check the next solution.
