iOS 10 on iPhone 6 Battery always shows 100%

Hi everyone, I updated my Iphone 6 (sprint) to iOS10 and since then my batter percentage is always 100%. The phone will die, I will charge it, it will go back to 100% and then never shows any lower number besides 100 until it dies. This happened exactly when I upgraded to iOS10 and the battery life/ percentage was fine prior. Any ideas or tips? Are others having this issue?

Had the same problem on my iphone 6 (iOS 10). I tried everything suggested on this site- hard reset, starting the phone as new...Eventually I took the phone to the service. They concluded my U2 chip died, due to wrong charging (bad cable, charging in the car etc). They explained that chip couldn't display correct values of the battery and it caused draining the battery even on stand by or random shut downs (even when phone is on its 30% or so).They replaced the chip (70 euros) as well as battery (30euros). That solved the problem. Other solution- when phone is charged to 100%, put it on low power mode and there will be no shut downs. On the other hand you will not get the best of your battery life, cause the problem with chip will still persist. Two authorised apple services didn't want to replace the chip ("we don't do this, you give your old phone to recycle and add 500 euros to get a new one"). Hope this will help!

It seems i don’t have the 100% stuck issue now, but the battery drains really fast, I am talking about it can go from 100% to below 20% in less than an hour, while i might be using it sparingly. I will get the battery low warning, and if i plug it in it would jump to something like 75 or 80%. I am using the latest 10.1.1.
