BEWARE! iOS 14.5.1 is Throttling!

[Paddle1]

Next question. How do I remove the settings app software update notification badge??! Back when I was on iOS 13 I would download the tvOS beta profile and presto it was fine and gone but it looks like that is no longer available on the beta profiles website or it needs to be updated. Anybody have any ideas? Guess I’ll just live with the red number 1 for awhile again until 14.6 is out and is confirmed to not be as buggy!

In Settings go into storage and delete the update.

Little disappointed macrumors hasn’t even ran an article about it

Yeah this seems to be getting kept rather quiet for some reason. Considering the lawsuits and PR that came from something similar in the past it's in Apple's best interest to address it ASAP, which is more likely to happen if people actually know about it.

I already saw a video where the iPhone 7 was lagging and getting outperformed by a 6th gen iPod touch. That iPod only has the A8 (like iPhone 6) and is pretty slow itself, which just shows how much impact this throttling can have.

It’s not that easy anymore. It’s not even downloaded. But maybe if I wait long enough it will just disappear. It’s happened before.

I tried this and it didn’t fix anything. So I used this method to go back to 14.5 and it is fixed now on 14.5. I’m going to stay away from 14.5.1. I bet they will fix it next week on 14.6 beta 3. Everyone will probably be stuck with this until they final release 14.6 at the end of this month.

YMMV obviously

I'm sure Apple will push out the 14.5.2 update this week. Apple would say "very small percentage of users experienced this"

Need some more mainstream exposure for this issue and it sucks there is no acknowledgment about it from apple. I’m not wasting 99 cents on geekbench 5 just to see if my iPhone 12 is affected. I bought geekbench years ago to confirm my 6s was affected with the battery throttling.

I didn't even know there was an issue, nothing seems different to me.
Only saw the thread and it interested me, so spent the whole 99p on Geekbench (didn't realise it was so cheap on iOS).
Results I got match Geekbench site.

They want you to buy the purple iphone

When I initially updated to iOS 14.5.1, it was super laggy. In games, the frame rates were horrible, and when opening apps, frame rates were dropping; however, since I did a clean install, it has been running as it used to on iOS 14.5.

 

[skardvin]

Don‘t know where I‘ve heard it (Marques brownlee maybe?!) and I don’t know if it’s true, but apparently after an update the iPhone keeps on updating files in the background which can take up to a day which would explain the problem.

But why, after a clean install, is my performance back to normal? Shouldn't it be updating files in the background after a clean install?

 

[skardvin]

Not just 14.5.1. Mine is doing that on 14.6.2 PB

R.I.P.

I had some lag and performance issues so I downgraded to 14.5 and all is well again.

I've found a solution to my case, Reset the phone and do not restore any backup, basically fresh reinstall. My geekbench score multi went back to normal 4031 instead of 2336. The minute I restored back my old backups, the throttling is still there. Basically, clean reinstall of everything fresh.

Are u just doing a simple factory reset once update to 14.5.1 ? Or u restore the clean ipsw files from itunes ?

simple erase all settings from Settings on iphone

simple erase all settings from Settings on iphone

I have done the same erase all setting on 14.6 beta 2 unfortunately the result still the same. Maybe i should try a clean ipsw install

 

[ferretex]

Maybe it’s just a Geekbench app issue? I ran my app yesterday and got half score on Multicore. I ran it this morning and back to normal…I didn’t restart or anything.

Threads like these remind me that I was correct in turning off auto update on my iPhone.

I would consider that the problem is in the application, if the iphone did not start to be stupid in opening applications and everything else

Everything works flawlessly on my iPhone 12. No issues. Just my 2 cents here…

update: apparently after awhile it went back slow again, tried clean IPSW install but still the same. Oh well, I guess it's 14.5.1 itself. Probably have to go back to 14.5

12 Pro here. Multicore also bring throttled down from 3955 to 2405. Single core score unchanged. My iPad Pro 12.9 4th gen scores unchanged.

Be glad you haven't been affected by this problem

 

[r.c.]

Multi core performance down for me significantly after update.

 

[maplingstorie]

Honestly this is a serious and legitimate issue. Surprised Geekbench hasn’t said anything when they were the first to report the differences in the batterygate days.

I personally do not think this is geekbench's. I noticed the problem when I was playing mobile legends after the update. Performance was horrible and I blamed Mobile Legend at first but then I went through this thread and noticed people are having the same throttling issue. I downloaded Geekbench later on and tested out and was right about the significant performance drop. So no, it is not Geekbench

 

[VespiYT]

No this is not just Geekbench, people have been using 3rd party software to check what speed cpu is running at when they experience throttle and it shows the cpu running very slow speeds
