IPHONE UPDATE CRASH 10.2.1

[Venky_Sree]

I am using a iphone 5. updated it last night to version 10.2.1. Had more battery draining issues from update 10, but now it got worse. The thing is frequent restart within 2 mins,battery indicator is unstable, it never goes to 100%. it switches off unevenly and in a point it reaches 2% then it works for a some time and after some time it boot loops[apple logo comes and goes].In the diagnostics list it shows frequent
1)stacks+backboardd
2)reset counter
3)jetsamEvent
4)stacks+com.apple.datamigrator
5)panic
The issues 1,3,5 are listed more. I have tried all the possible things such as hard restart,resetting the device to new and the thing is that im just using wifi , if the cellular data is on it switches off immediately. I did not change the battery cause that it might be worthless if still the above errors . that is why need a help kindly do help out, I Want to know the problem is.

Advance thank you
