    beta 5 and now the latest official release my multi core score has dropped 1000 points from 10,500 to 9,500

    Anyone else experience this? This is on an iPhone 8 Plus. Not a fan of this, I’ve noticed just when switching between pages it hangs up a bit in between.

    This is the highest I’ve gotten so far since the new update that’s with all apps closed on background and a hard reset

    Doing a Geekbench performance test after you download a update is a great way to get an inaccurate/low reading. Try again later tonight or tomorrow and it will be back to normal

    I doubt it because I was beta 5 since the day it was released and got the same results last night on it but I will redo tomorrow to confirm

    Your device is still indexing and doing things in the background for a few hours after an update, that effects the cpu performance..

    The urban legend indexing will never die :)

    Indexing is a matter of a few minutes. You can watch on every windows system (much larger os!) that this only takes a few moments, and this is what happens on your device after it shutdowns and shows the apple logo and the progress bar.

    Once the iOS is back and running, all indexing is done. Your personal data index is a seperated part, this isn’t reindexed, as there is no change in that.

    I am aware but this performance issue has been going on for a week now with beta 5 as well and I’ve ran Geekbench before shortly softer updating the same day and never had this massive performance drop

    Has anyone else ran it on their iPhone 8 or x to see if they experience the same?

    I personally never run benchmark tests for a few days after an update so I have no personal experience with the performance loss but, many people complain of low benchmark scores as well as poor battery performance after an update that usually straightens itself out after time so something’s going on

    You may have to restore using iTunes and see if that helps any.

    No laptop at my home anymore, between phone and tablets when my last one kicked the bucket I never bothered getting another lol

    Might just wipe the phone and restore it if this is still underperforming tomorrow

    I was getting multi core tests of around 9500 on my X, did an Alt update on my Mac and was still getting a low score, left my phone on its charger for an hour or so and did another test and got the following.

    Good to know, sitting on the car charger right now and going to test when I get home. Hope for the best, thanks for sharing!

    So what do we think is causing this issue on mine? Still no change
    --- Post Merged, Oct 30, 2018 ---
    Single score is right where it needs to be but multi core won’t budge

    Did you try hard reset? Idk how to envoke that on i8 and up, i used to have 6s, usually you just hold power and home button

    Btw why are you consern about the numbers? Is your device fast? Responsive? Opening apps like the iPhone 8 should? No need to worry

    Actually what prompted me to run the benchmark was because it hangs up a bit when switching between recent apps and when going back on webpages, it hangs for a second before it would respond

    This obviously was never an issue for me on my 8 plus. And no I don’t mean opening a million apps and seeing how many stay open. I mean switching back and fourth between two apps. Like Facebook and messenger, YouTube and safari, safari and my two factor authentication app etc... Things I’ve always done and recently the phone struggles a bit.

    I’m aware 9700 is still a high number for a multiscore but there’s obviously something going on behind the scenes to knock down 1000 points and seems to be effecting day to day performance

    This phone was just freshly redone not even a month ago as well. Since beta 5, somethings not happy

    My Xs max seems to be quick on 12.1 beta 5.

    I have done this test a few time within one hour without doing anything special and got scores from 9154 to 10240.
