BEWARE! iOS 14.5.1 is Throttling!

[skardvin]

Updated from iOS 14.5 yesterday to iOS 14.5.1 on my iPhone 11. After the update finished, I was playing CODM and noticed the frame rates were horrible. I checked my settings to make that it was set to the max frame rate, which it was. I then ran a geekbench test, and the scores I got were horrible for the multi-core. I then rebooted my phone to no avail; it was still super slow in games and in opening apps. I then proceeded to do a clean install which seems to have fixed the issue. Now my geekbench score is normal, and performance is what it used to be. What is going on, Apple? Anyone else having this issue? Upload a screenshot of your geekbench score on iOS 14.5.1 and tell us what device you have.

UPDATE: It would seem I am not alone in this issue. Nick Ackerman and ZolloTech are having issues as well.

Is battery at all related to this? Express VPN normally accounts for 5-10% of my daily battery usage. Since 14.5.1 my VPN accounts for 50-60% of my battery usage.

12 pro here seems fine to me.

Battery life hasn’t been any good on 14.5 and 14.5.1, WTF is going on at apple these days, are they turning into the next Samsung. 🤦‍♂️

Getting 2 hours less battery life on my 12 pro max.

Yeah, I don't think it is happening to everyone who has updated to iOS 14.5.1, but it is definitely happening to some.

Yup my iPhone 12PM is completely throttled with this update. Single core is fine but multi core scores on GB 5 are nearly half of what they should be.

So, it wasn't just me that felt something had gone horribly wrong after updating.

XS max here, working fine after update.

My xr is totally normal but my backup 7 is like it’s running in treacle. There is definitely something going on with this update.

Heard someone on here say it only throttles when you restart your phone, then once you lock and unlock it, it goes back to normal. 🤔

This true?

It does seem to throttle more during the first several minutes of being on then recovers to a usable state. Still noticeably laggy on my 7.

12 Pro, didn't have any issues after updating. I always reboot after the update finishes. This time, I updated via the IPSW.

Not throttling (or at least I haven't noticed any drop in performance) but it has been working harder (getting warmer) since the last update. I assume the update was major enough that there was a lot of reindexing and such going on and that it will settle down in a few days.

My multicore Geekbench score on my 11 pro max is down 600 points from where it usually is.

My 11 Pro is slower and GB5 score is way low

I haven't noticed throttling per se on my 12 mini, but I am noticing a lot more apps reloading when switching between apps.

11 Pro Max my scores exactly the same for single core, and 5 pts higher than ever.

 

[Itsedstech]

Same issue here 12pm cod mobile is laggy af

This only happened to me until I did a hard reboot. Works fine after.

horrible for the multi-core.

This post seems rather meaningless without the values pre-update…

 

[DM_DM]

There is a visible lag. No longer snappy.

 

[thejadedmonkey]

My 2016 SE is just as slow as always.

A hard reset fixed my Geekbench score. All is well on my 11 pro max.

No go for me. Still as bad after a hard reset on my 12PM.
