    see my processor in geekbench 3?? ARM @ 1.14gHz.. pls help. I wanna know if this is normal. coz whenever my phone is 80% and above.. the scores ranges from:
    single core score : 2500-2550
    multi core score : 4400-4450

    Also my iphone se is slow whenever I see that my processor’s low.
    take note that I still have 33gb/64gb left.

    Hello,

    I do not know of any part of Geekbench that would cause this kind of result pattern. It may be an issue with battery health on your device, so you may wish to take you phone to an Apple Store to get it checked out.

    No, I’ve let an apple staff run diagnostic on my SE and he told me that the battery,software,hardware,etc has no issues. it may be due to ios 11 beta. I’ve hard reset my phone already and the issue’s gone.

    I’m also getting same experience, before iOS 11 it getting about 2500 and 4400 on single and Multi core, after iOS 11 it getting 1400 and 2400, same with antutu average on 60k.

    Later today I’ll try hard Reset it anyway.

    No Ju Ming! you'll regret hard resetting it. that's not gonna solve your problem. you'll just delete your files.. maybe you got ur low power mode turned on.

    I am having the same on my iPhone SE iOS 11.0.1. Performance cut in half when battery life is less than 70%. Prior to iOS 11, the scores were consistent no matter how much battery left unless low power mode was on.
    This problem is not happening on my iPad Air 2. The same performance at 100% and 9%

    Is your iphone SE based on Samsung Made A9 instead of TMC ?

    Check on Antutu info for processor.

    Hi,

    Thank you to everyone for letting us know about this. We are investigating this issue, but so far have been unable to reproduce it at our office. I will let you know right away if we're able to provide any more insight into this battery-dependent performance.

    For those experiencing this issue, if you could provide a link to your results for the iPhone SE in the Geekbench Browser along with the approximate battery percentage that the benchmark was run at, it would be a great help and may help us isolate this issue more quickly.

    Best,

    it would be great if ya'll guys find a solution or the cause to this problem. I'm really bothered. I saw in the tech reviews that even though they have 50% or below battery level, they can still get high results.

    As far as I know, it’s happening on Samsung processors. 1800 & 3000 score at 32% battery life (sometimes even lower). Jumped to 2500 & 4400 at 100% battery. I didn’t have this problem in iOS 10. The same result no matter how much battery left unless low power mode was on.

    Now I'm using another brand new SE with Samsung processor too, and it's
    using ios 11.02 and it doesn't suffer slow down, maybe battery wear affects
    the processor speed?

    By downgrading to 10.3.3?

    Hi jedrequiem,

    I'm glad to hear that the issue seems to have disappeared. Do you know if there were any updates or changes to your phone which could have caused this issue?

    I'm continuing to investigate on our end, though any clues which could help us narrow down the cause of this issue would be greatly appreciated.

    All the best,
