iPhone 6s Battery draining under OS11

My iPhone 6s was fine on iOS10. I would get around 8 hours from it with regular use. Now with iOS11 its been flat within 4 hours. I have been waiting for the minor updates hoping the battery life would go back to iOS10 standards.

It hasn't. Is everyone having this issue with battery life or maybe I need my battery replaced. Funny how I suddenly need my battery replaced with an OS thats supposed to be optimised for my hardware..

MacBook Pro, macOS Sierra (10.12.1), 2.0 GHZ i7 1TB Drive, 16GB Ram

Hi

If your battery is over 2 years it will need replacing make an appointment at Apple store.

Or go to Support.apple.com for posting details Mine took 4 days

Go to apps store download Battery life it will test your battery condition.

Before doing that try resetting your all settings on your iPhone and use your iPhone in low power mode.

I hope this helps. If not, do as Brian said.

Thanks for reaching Apple Support Communities.

Cheers Brian and Stuart!

My iPhone 6s does that too, but after I updated to iOS11.2, it works much much better. Make sure you are running iOS11.2, not just 11.

If that doesnt work, you might need your battery replaced. Contact Apple for replacement options: support.apple.com
