P: Lightroom iPad/iPhone Device overheats & brightness dims

After some update there is a change. The phone (iphone 15 pro) still heats up quite a lot, but despite this the screen does not dim, photos zoom in and out without lags. BUT sliders, brushes, etc. are still laggy, works with a delay, as if you are working in power saving mode

It's hilarious this has been a problem for 7 years and adobe just swipes it under the rug like nothing ever happened! I can relate to the person above me, I also used the Lightroom app for years on android and as soon as I began using it on ios I started experiencing overheating, screen dimming, battery drainage and lack of precision when I would want to make delicate editing, this all points towards extremely poor optimization, especially for such a simple app, this is ridiculous!

Previously an android user and had no issues with the Lightroom app. Now as soon I moved to the iPhone 15 Pro I'm having this same issue. Quick and serious overheating and screen dimming as a result. It's so bad it's burned a magsafe ring into my phone case

Why is this thread marks as "Solved"? This problem is not solved, so please take this "solved" off and maybe try to help us, before we all go from lightroom to another app on ipad.. 

same issue here.. have brand new iPad Air with M2 for 2 days.. and I can't edit single photo without display is dimming and ipad is overheat.. I bought iPad just for photo editing and now I can't imagine to edit 50plus photos.. after about 30 seconds editing RAW photo (33mp) display sudenly dim. I don't want to go to Affinity as I am using Lightroom on my Macbook too....

I thought I'd share my experience here as well, being a long-time Lr on iOS user.

iPad:

I have 3 iPads: (1) a 2018 iPad Pro 11" 3rd gen A12X, (2) a 2023 iPad Pro 12.9" 6th gen M2, and (3) a 2024 iPad Pro 11" 7th gen M4. On all three iPads, if I am editing and scrolling through a lot of photos, the iPad gets hot in the area (presumably) where the GPU is. Sometimes it gets quite hot. It never gets hot enough to cause the screen to dim on any of my iPads, and the heat fades quickly when I stop flipping through photos or doing heavy edits. For example, last night after our local fireworks display on the 4th of July, I imported more than 250 full size CR3 raw files onto my iPad 7th gen M4, scrolled through them marking my picks, went back and edited the picks and exported some back to the camera roll. A little heat during the import process, and not much after that. 

iPhone:

I'm currently using the iPhone 14 Pro, but have had nearly every iPhone and have used Lr extensively on my phone since it was available. I've noticed the same heating up, especially near the cameras, occasionally quite hot. This happens a lot when shooting HDR with Lr Camera and then waiting for the processing to occur. Again, while my phone has gotten quite hot, I've never had the screen dim as a result of Lr running hot. And the heat fades quickly once the processing is done.

I will add that I also live in Florida as noted by one responder above, and when I'm out in the sun with my iPhone, I have the dimming issue caused by the heat of the sun. This happens not with Lr, but with any app, even when I'm not using any apps and just looking at the Home Screen. This happens to me sometimes even if the phone is in my pocket, when I'm sitting in the direct sunlight. This is of course not related to Lr but shows how the iPhone can be sensitive to heat.

My ipad pro keeps on overheating after 3-5 mins of editing. The screen dims afterwards. And it takes time to go back to normal. Once it's back to normal, after 3-5 mins, again the ipad goes back to getting super hot and screen dims. It keeps repeating and it hinders me from getting effective with my work. I can't edit hundreds of photos if this keeps happening again and again. I bought the latest ipad but the issue comes back.

I suggest everyone to start emailing them about this problem, because there's probably no point in writing here. So I recently wrote to support, they told me that they have not received such complaints yet and as if I'm the only one with such a problem with overheating in lightroom mobile. And actually this thread is from 2017 bla bla bla completely ignoring the presence of 8 pages of comments. Then they redirected me to my email, I described the problem in an email and left a link to this thread. (no response yet)

I bought a $1200 iPad Pro and returned it because of this issue, plus the fact I can't stitch panoramas (and the photoshop app sucks). 

Looks like if you try to report a quality issue on the iOS app store it takes you to adobe. So instead I just reported it as a scam or fraud which goes to Apple. I suggest everyone else do this. Shame on you Adobe!
