I've seen a few that the battery was years old and it was failing in odd ways. I will not spend time on old batteries today. Too cheap to think or chat about that.
Not a sure thing since the phone is so old. I do not think it's the iOS upgrade as we have a 5s here and it's fine on the latest iOS. But it's been well cared for, has a new battery and a Jackery battery case.
I have a iPhone 5s which is now restarting continuously, After upgrading it to IOS 12 from IOS 11, Even at the time of charging it restarts continuously. As of now what I am doing is, I switch off my mobile then I charge it, So that it will become 100%. After that I start to use it, Even though it restarts some times while i am using.
I try to downgrade the software IOS 12 to IOS 11, I tried in iTunes and other online softwares. I am unable to downgrade it. Anyone have any idea how to downgrade it to IOS 11. Can anyone tell me how to downgrade it in a detail way, I searched many times online, I did not find the solution for it.
All are welcome to respond my question, Who gone through this issue, How they fixed it. I gave my phone to service centers too, They said they tried all, Still the issue remained same. I hope all folks who go through this issue will have a solution on it. Please help me in reply.
Thank you one and all for your support.
