    I installed 12.1 on my 6s about two hours ago and the battery drainage is incredible. One example: 20% to 10% watching a six minute 480pixel on YouTube video within about three minutes.

    Is anyone else experiencing this?

    Battery usage right after an install can be atypical as there might be some post-install things that the device is still doing. Give it a day or two and a charge cycle or two as far as seeing how the battery life is like.

    Roll back before it's too late. You're not the only one experiencing the issue.

    Based on a couple of hours right after install? There are those who have some type of battery issues with 12.0/12.0.1 as well, by the way.

    Thanks guys

    Thing is I can’t roll back as I no longer own a computer, only an iPhone.

    Without iTunes on a computer to help you roll back to older firmwares, looks like the only solution for you is to pray that future updates solve the battery issue.

    My 6S+ is still on 12.0, and getting 7-8hrs usage per charge. Still undecided whether I should update to 12.1, or wait for future versions.

    Curious, are you saying that the on screen and off screen times in the battery usage section add up to 7-8 hours for you, or you are measuring that some other way?

    I consider myself a relatively light user, such that my 6S+ is able to last me 2 days on a single 100% charge.

    I totalled up 'on screen' and 'off screen' times in the battery usage section. Most of the days I hit approximately 4 hours of usage and the battery usage graph for that day didn't even touch the 50% battery usage line. Simple math would then calculate how much usage I'll get out of it if I had drained the full 100% charge.

    I consider screen off time as usage primarily because I listen to music frequently with the screen off and through my Airpods. I don't know how anyone would consider listening to music from my iPhone, even with the screen off, as 'not usage'.

    My battery capacity is at 100%, before anyone starts asking.
