    Do you find it satisfactory, that the battery life of my iphone gets from 100 to 0% in 4 hours screen on ?

    How old is your SE?

    What is the battery health?

    Could be time for a new battery.

    There are lots of people on here reporting battery problems with iOS 12 on the iPhone SE, including myself.
    12.0.1 has helped for me so far, at least to calibrate the battery properly i.e. draining to 1% and letting the phone shutdown. I couldn't do this on 12.0.

    As of this week, you can't downgrade to iOS 11 as Apple have stopped signing the software.

    12.0.1 is the latest publicly available update. Simply check for updates in Settings - General - Software Update and install it.

    No, it’s not normal. It’s what’s happening to a lot of us, but it isn’t normal. Apple needs to fix this iOS 12 issue.

    Apple's stated battery life is:
    Internet use: Up to 13 hours
    Video playback: Up to 13 hours
    These are 'screen on time' statistics.

    I still easily get 10 hours of screen on time from my iPad Air 2 on iOS 12, same as iOS 11.
    The iPhone SE should be able to match this but currently doesn't under iOS 12.

    See the post below yours. It sure as hell isn’t the 4-6 hours a lot of us are getting. I easily got close to 10 hours on iOS 11 and changed nothing but updated to 12.

    Thank you

    Don't think the "usage" time in previous iOS versions is the same as "screen on" time in iOS 12.

    True. Good point. Wasn’t it combining screen off and screen on time before? Either way, my battery life has been almost halved by iOS 12.

    Yesterday running iOS 12.0.1 I got 7 hours of screen on time, with 25% battery remaining. Which is much better than 12.0.

    I had previously calibrated the battery - after installing iOS 12.0.1 I ran it down to 1% and allowed the phone to shutdown. Then charged to 100%.

    by the way how did you install ios 12.0.1? I did it through settings, but they say that that's not so good because it can have bugs. Does this make any sense to you?

    Just a normal update via Settings - Software Update.
    The next thing I was going to try was a DFU restore via iTunes, but thankfully battery seems OK now.

    If you are playing Pokémon go during those 4 hours... sure perfectly normal? We’d need a little more detail about your usage.

    I just got a brand new battery in my 7 and after 3 hours and 8 minutes of screen on time after a day with a half hour of Pokémon go, some YouTube and safari and messages I was down to 29%. YMMV. It all depends on your usage.

    If the brightness is up, your battery will suffer. If you have low LTE signal and you are hammering away on safari your battery will suffer. Apples quoted numbers are total crap and they rely on lab tested tests that aren’t even close to real world scenarios. I’d say getting 3-7 hours of screen on time per day is the range of all iPhones nowadays depending on what you are doing.
