iPhone 17 Pro Max: Notes app overheating and battery drain with JPG images

Hi everyone,

I'm encountering an ongoing performance issue with the native Notes app on an iPhone 17 Pro Max running iOS 26.

Whenever I add a small JPG image to a note, the device starts overheating intensely within seconds, and the battery drain spikes dramatically.


This behavior isn't new I have observed it continuously since iOS 18 across updates, and it remains completely unresolved in iOS 26. Looking through discussions here on the forums, severe overheating and high resource consumption in Notes is clearly a recurring issue for many users.


Background indexing and analysis processes shouldn't push hardware to thermal throttling just for attaching a simple, low-resolution jpg.


Has anyone found a reliable workaround or setting that stops Notes from locking up CPU/GPU cycles on simple image insertions?

Quick update on the severe overheating and battery drain issue when inserting JPGs into Notes: I managed to resolve it.


Here is what fixed it:


1. Went to Settings → [Apple Account] → iCloud → Notes and toggled sync OFF.


2. Confirmed deleting local notes from the iPhone when prompted (everything remains safely stored in iCloud).


3. Restarted the device.


4. Turned iCloud sync for Notes back ON and waited for the database to redownload completely.


After the fresh resync, the issue completely disappeared.

Hope this helps.

I can state that my wife doesn’t have that issue on her iPhone 17 Pro Max using iOS 27.2. May it’s time to upgrade and put iOS 26 behind you.
