iPhone 6 Plus 128GB (35GB free)
Running IOS 9.3.1 (keep meaning to upgrade to 9.3.4 but not got round to it yet).
Checking mail this morning before setting off to work and phone was very sluggish in the app (it had been fine until then).
I gave up and set off to work.
When I got there it was still sluggish so I turned the phone off (hold lock button then slide to power off) and then restarted the phone.
When the Apple logo came on it stayed on screen for a good 15 mins before the phone started and asked me to unlock.
Phone has worked fine ever since.
Is this a sign of something to worry about? Is it worth upgrading to 9.3.4 or is phone at risk of falling over?
