How do I fix 9.2.1 update not charging issue
I Need to roll back my iPhone 4S to 9.2.0.
The new 9.2.1 update created a significant power drain and right after updating to 9.2.1 the iPhone 4S lost the ability to run or charge when the phone is turned on. The phone now only charges when the phone is turned off.
I used the app called BATTERY to find the apps using the most
power and turned them off, I also removed unneeded apps, but there was no significant improvement.
Occured after update to 9.2.1
Suggestions, similar experiences, will be appreciated!
iPhone 4S, iOS 9.2.1, null
