IOS 9.3 battery drains

Hi Steph2875,

What kind of issues did you have and what other things did you try? Also a bit curious how you were able to track it down to the failed messages. I'm having problems of my own with battery drains but I have a huge archive of messages (that I want to keep) so I'm not sure I will be able to track down all failed messages.

iPad Pro pencil Not working.

2) severe battery drain to zero after only reading emails, Apple call the Godzilla crew to get this fixed. Urgently needs immediate attention.

3) iMovie content themes vanished

Try this little bit of Voodoo that's worked twice now for me (9.3.1 > 9.3.3 and 9.3.3 > 9.3.4).

Try shutting down your device and any Mac you've used for setup or iTunes sync for your device.

Then power up your device with the Macs still shutdown, and see if your battery issue is remedied.

My daily usage shows that my iPhone 5 battery drain (IOS 9.3.5 and now, IOS 10.0.1) occurs only when I listen to my music via Bluetooth in my car. The iPhone then gets notably warm, if not hot.

This overheating by itself justifies battery drain.

Then why this problem didn't exist in IOS 9.2 is for Apple to find out.
