iphone battery do not last half day after updating IOS
Iphone battery life never been the best but i always go trough the day. after I have updated the IOS about a month or 2 ago I start to face a very very low battery life.
I don't remember now the number of the updating IOS but it was that with the patch of some kind of virus or exploit about CPU or something.
Now too often watching the battery percentage dropping of 3-5 or more percentage in seconds! In the same period I heard that so many other people had the same problem.
Long story short= the battery was fine.
After updating the IOS the battery is = Sh*t.
after that update i have updated 2 more time the IOS but the problem still there.
Any solid solution? thanks
iPhone 6s, iOS 11.2.6
