Some iPhone 6/6s and iPhone 6/6s Plus users who have updated to iOS 9.3.1 reported that they are experiencing serious battery drain and their device getting unusually hot. In some extreme cases, users were noticing the battery percentage indicator dropping in a real-time manner.

Based on the input of some software developers, upon iOS 9.3.1 update completion, the iPhone 6/6s will perform “some intensive CPU activity” likely related to iOS cleanup, Spotlight and automatic updates. This could be one of the reasons why it’s using so much battery and when the CPU load is high, it will make the device warmer.

Alright, now that you know some of the reasons why your iPhone 6/6s is having this issue, here are some possible fixes or remedies you can try:

1. Leave the iPhone in peace

It is advisable that you turn the screen off and let the iPhone finish whatever it’s doing after the update. If you haven’t updated your iPhone yet, choose a downtime when you don’t really need to use your phone such as after office hours or on a weekend.

2. Hard Reboot your iPhone

This basically forces your iPhone to reboot by pressing the home + sleep/wake button simultaneously for 10 seconds. The Apple logo will appear and your iPhone should start normally. Any process that was stuck in the memory should have been flushed away. Some users who were experiencing warm iPhone were able to fix it after doing a hard reboot.

3. Check Location Based Reminders

Users should also check their iPhone’s location based reminders and background refresh settings to make sure the iOS 9.3.1 update did not change these settings. If turned on, they may further increase battery draining.

4. Erase your iPhone

If all fails, try to run a backup first and then erase all documents and settings and then followed by restoring from backup. It also’s highly recommended that whenever you update your iPhone, do it on your computer via iTunes instead of using the OTA (Over-the-Air) update. This somehow “magically” fixes most iOS related issues.

These possible fixes are recommendation and there are always some possibilities that the problem won’t be fixed. However, if one of the solutions above remedied the issue, please don’t forget to leave your comments, +1, Like or Tweet this post!
