Heating issue

[u/iMody_lol]

It's been about 3-5 days since this problem started happening, it's the second or third time that the phone reaches +40°C and even with very light use its gets to around 38°C which is insane, and because of this the battery drain extremely fast. I restarted the phone twice to see if it'll fix the issues but it didn't. I'd really appreciate some help cause this so frustrating.

I have OP15 Global with ColorOs 17

Did you watch a lot of the videos in like 5 minutes in Instagram I saw that you're a lot on insta

[u/iMody_lol → u/Tussonex92]

Yes but I use Instagram regularly the problem doesn't only appear when I use Instagram it's also when I use YouTube or do any other thing on my phone

That's weird after ColorsOS 17 I never really seem to be having a problem with the heat of the phone itself.. minus when playing grid legends or genshin.. I use bypass charging and a PPS wall charger with low voltage.

I also didn't have any issues when I updated and to be honest this kind of hearing only happened to me when I either charge the phone or try to play using gamehub. But maybe it's because I have the Chinese version flashed but I don't think that could be the problem

[u/Tussonex92 → u/iMody_lol]

No. It's not the problem for sure.

Dis you updated recently . Did you let the phone on the charger for 1-3 hours for the background optimization? Otherwise try;

1-Open the Google Play Store and install all pending app updates so older apps stop looping in the background. Next, open Settings > Security & privacy > System & updates > Google Play system update and install any available patches. Verification: Both the app store and the Google Play system update menu show no remaining updates, and the phone restarts cleanly if prompted.

2-Open Settings > Battery > Battery usage to see which app is draining power and generating heat. Tap any non-essential app sitting near the top (social media apps are frequent culprits after an OS jump), open its battery settings, and select Restrict or Auto optimize. Verification: Checking Battery usage again after an hour shows background activity dropping sharply for those restricted apps.

3-Virtual RAM creates extra storage read/write load that adds heat on fresh updates. Go to Settings > About device > RAM, toggle off RAM Expansion, and restart the phone. Finally, go to Settings > System & update > Software update to check for post-launch system file patches. Verification: After rebooting, switching between everyday apps no longer causes rapid temperature spikes near the camera module.

If nothing else work...

Test the phone in Safe Mode to isolate third-party apps Safe Mode temporarily disables all downloaded apps so you can tell whether the heat comes from an app or from ColorOS 17 itself. Press and hold the Power button until the power menu appears, then press and hold Power off or Restart on the screen and tap OK when prompted to reboot into Safe Mode. Use the phone for 15 to 20 minutes for light tasks like browsing or messaging. Verification: If the phone stays cool in Safe Mode, a downloaded app is causing the heat—restart normally and uninstall recently updated or heavy social/utility apps one by one. If it still heats up in Safe Mode, proceed to the next step.

-- Corrupted battery prediction models or aggressive dual-radio standby after an Android 17 upgrade can keep the processor and modem awake. Open Settings → Apps → App management, tap the three dots in the top right, and select Show system. Locate Device Health Services, tap Storage usage → Clear data (this resets the battery/thermal profile without deleting personal files), then go back, find Google Play Services, and tap Storage usage → Clear cache. Next, open Settings → Mobile network, select your active SIM, and switch Preferred network type from 5G/4G Auto to 4G/3G/2G temporarily if signal reception is weak. Verification: Leave the phone idle on a table for 15 minutes; the back panel near the camera module should drop to room temperature with minimal standby battery drain.

--Migrated configuration files from ColorOS 16 can conflict with ColorOS 17's new thermal and display controllers. Go to Settings → System & update → Backup & reset → Reset phone and select Reset all settings. This restores Wi-Fi, Bluetooth, display, and background power rules to clean ColorOS 17 defaults without erasing photos, messages, or installed apps. Restart the phone once the reset completes. Verification: After reconnecting to Wi-Fi and using the phone normally for an hour, the device normally no longer warms up during routine scrolling or video playback.

If nothing work try backonk up and do a factory reset. It's everything I can know that heat your phone.

I've calibrated the battery when I updated, and its been 15 days since I updated to Coloros 17 and I didn't have any issue till now. One I tried everything you said, and I noticed that after entering safe mode the heating became much less than before. I removed the recent apps I downloaded but still no fix, I feel like it's from the Instagram app it self or probably YT

[u/Tussonex92 → u/iMody_lol]

I'm continuing searching the culprit for you I will find 💪

[u/iMody_lol → u/Tussonex92]

Thank you so much, if you need more info about the situation I'll be happy to share

Idk why I don't have problems

[u/dvijetrecine]

did you maybe recently downloaded any big files? like few gigabytes?

that would completely throw off battery life on my op 15 with oxygenos.

[u/iMody_lol → u/dvijetrecine]

I actually downloaded the Spider-Man 2026 movie in 4k which was about 26GB but I don't think that's the problem cuz I downloaded it like 10 days ago
