    Hi guys,

    Apologizes if there is already a thread on this.

    I upgraded to ios 9.2 last night and the battery on my iPhone 6s Plus seems to be draining twice as fast as it would have on 9.1?

    Any one else having this problem ??

    I wouldn't say twice as fast for me. But I did notice it draining faster, doing routine things on a normal day. Standby time is still solid as can be.

    No change here. Sometimes an update can change Settings. Check those. Also, often times we use our phone more right after an update to check stuff. That uses more battery in itself.

    No difference here. If you continue to have a problem you might want to boot into recovery and reinstall iOS in iTunes.

    I am also having the problem. I use this phone extensively and I am very aware of how it performs, battery life, etc. Since updating to IOS 9.2 I have noticed that when I am using an application for more than a few minutes, the phone heats up tremendously. I can even feel this through the apple phone case. It never did this before updating to IOS 9.2. Yesterday, when I got to work in the morning, the phone warned me that I had less than 20% battery remaining, and I had only been listening to podcasts on my way to work. Completely unacceptable performance in my opinion. I have an appt at the apple store on Sunday to see if this can be fixed.

    I have notice a difference since I've updated to 9.2. I'm going to downgrade back 9.1. Apple will allow it up to two weeks after a new update comes out.

    The key phrase is "up to". They can stop signing 9.1 at any time so the sooner the better for you. Good luck and let us know if you notice a difference!

    I have not had any change in battery life. You may want to do a fresh install. Did you do an OTA update or did you hook it up to iTunes to update? If you hooked it up to iTunes, the update is almost 4 times larger than the OTA update because you are getting the whole OS plugged into the phone instead of a patch. You may have had an issue based upon doing the OTA update.

    Do a fresh install after backing up your phone and restore from recovery. It won't take long and should resolve your problem.

    For me it's the opposite. 9.1 was a battery drainer for my 6S Plus, so I reverted back to 9.0.2. When 9.2 was released. I installed 9.2 OTA and my battery life has been a lot better. I can still get 15 h - 16 hours of usage on a single charge.

    Have to agree here. Prior to the update, my 6S+ would stay at 100 percent charge overnight. Now, when I wake it first thing in the morning, it's been between 96-98 percent. Only thing that has changed has been the update.

    Try a restore as new first.

    I tried to downgrade, but I got a 1394 error. I was taking the steps to downgrade to avoid the 1394 error. This is a real big pain in the but. I did reset all my setting, but that didn't work either. I'm going to try that.
