Here's Why Your iPhone Suddenly Dies Even When the Battery Is Full
Jan 21 2016
If the manual fix does not work Apple is encouraging users to get in touch with its contact support.
While the new update is meant to contain security updates and fixes for bugs, it does not rectify the battery indicator issue witnessed some time ago. As such, the phones generally display a higher count of battery level than it actually has resulting in users falling short of battery at the most unfortunate of times.
Apple has acknowledged that some iPhone 6s and 6s Plus users are facing issues with the battery percentage display not being updated. As you use your iPhone 6s or 6s Plus, it may not be showing you the correct battery percentage up in the corner.
However, in order to fix the freeze, Apple asked affected customers to try restarting their phones and following these steps.
Apple is encouraging consumers experiencing the problem to reset their phone and check that "Set Automatically" is activated under the iPhone's Date and Time menu. That's annoying from a "is my phone about to die" standpoint, but at least your total uptime is the going to be same whether your iPhone has this issue or not. According to Cnet, when the iPhone 6s and 6s Plus was first released back in September, it was then discovered that battery life varied depending on the chip they had inside. So it could show you have 80% life battery when you know you left home with only 50%. It is emerging that some of the devices are providing incorrect battery percentage readings.
We remind you that the iPhone device comes with 32 native applications, which is a huge number. You can grab it now through the Update tab of the Mac App Store, or you can manually download and install the Combo Update version from Apple's support site. Depending on the difficulty of the fix, and on timing, we expect the problem will be addressed in iOS 9.2.1 or iOS 9.3.
