I have both the 10.5 and the new 12.9 - love them both.

However when running Procreate, they both get very warm, and it causes the screen to auto-dim to cool off after hour + sessions. Which is disappointing. What's the purpose of having a brighter screen if I can't run my pro apps on full brightness?

Is it possible that Procreate can update their app do preform better on the new iPad Pro's?

Interesting. How many layers and what DPI are you normally working with? This particular piece I was working on was about 20 layers at 300 DPI.
The piece I've been working on lately is about 25 layers. Not sure of the DPI. The 10.5 is my first iPad and I'm still getting to know Procreate after finally crossing over into the digital art world.

Could be I'm not noticing it either. If I do, I'll report back.

Getting the same thing with my (2017) 12.9, using Procreate.. not many layers, but large canvas at 300dpi. A restart and reboot didn't help.

Just guessing here, maybe its some sort of type of safeguard the iPad is trying to conserve energy or use less battery draw, if the application is fairly intensive with power draw.

For Example, of the fail safes on the iPhone will also dim the display if temperatures are exceedingly either are too low or too high for normal operation.

I'm finding this too on a 10.5. Did you manage to resolve the issue or did you return ?

This is just something all Apple devices due to protect themselves from overheating. Rather than turn the device from overheating, it autodims so you can still use it. This has been the case from the earlier iPhones to current. Not much can be done other than keep it super airconditioned or something ot keep the device cool.

Also would be curious on if these iPads are in cases (thicker?) and or being used on a surface which gets warm, holds heat in. Could just be the heat can't dissipate.

I can’t say I have ever noticed this on my 9.7” iPad Pro, it has no case, and I have had it running very hot; charging and running a large world game map.

I’ll see if I can replicate it, and see if it was just me not noticing it.

No this isn't that. I've never had this issue in any iPad I've ever bought. When the light dims you actually see a noticeable jump in lighting adjustment. As opposed to the usual very subtle and almost unnoticeable gradual dimming. This is a 'Jump' from one light settings to another.

Had this issue last night while watching a tv show and playing a game while charging, happened twice, was a very noticeable drop in brightness, fixed itself once I unplugged the iPad. I don't use a case. First gen 12.9. Probably just a feature to help protect the device, but it is rather annoying.

I have this problem on my iPad pro 12.9" (2017) when running procreate... The files i'm working on are around 6000x2500 pixels at 300 DPI

Watching a video, charging and playing games WILL heat a phone up. The CPU creates a good bit of heat not to mention the backlighting. If it too warm it will dim the screen until it cools down or even throttle the CPU if needed.

Procreate is also a big user of the CPU and other have reported the same.

I have this issue on my 10.5 as well. It dims the display when I'm sketching stuff in notes or simply browsing the web. You don't need to use a high CPU app.

So glad I found this thread - my 10.5 iPad Pro is dimming regularly, and then reverting back after a time. Irrespective of auto brightness settings. I live in a hot country, often working outside in full brightness, and the 10.5 is my primary computer so I use some apps quite intensively.. I feared I had a hardware problem but now suspect this is an overheating issue.

Is this (presumably safety) feature of iOS documented anywhere? Any idea how to mitigate, extent to which overheating is dangerous to iPad hardware etc?

I'm trying to find the official Apple article (there is one), but I had this in a chat with my brother where I was discussing a similar issue where I thought my replacement 10.5 had a duff screen but it had dimmed due to syncing/installing apps/heating up

These are some features that will be affected by the changes iOS inflicts in order to prevent the device from overheating:

  • Camera flash will be temporarily disabled.
  • Cellular radio will enter the low-energy state which might affect your signal and Mobile Data.
  • The display will dim or turn black temporarily.
  • If the device is plugged into the wall socket, it will stop charging.

Try to never use your iPad in direct sunlight when it is very hot outside. I would try to find a cooler place to use my device. I live in Florida and it has been so hot you run from one air conditioned place to another.

Interesting, thanks. This app apparently gives you a read of your device’s internal temperature, but it’s MacOS only (you connect the device): http://coconut-flavour.com/

I can’t seem to find an iOS app that can do it.
