If your iPhone has been heating up like crazy lately, especially after updating to the latest iOS or playing games like Genshin Impact or streaming on 5G, you’re not alone. Thousands of users are reporting overheating issues across Reddit, forums, and social media. But one viral TikTok hack has surfaced in 2025, and surprisingly, it actually works.
Here’s everything you need to know about the iPhone overheating fix that’s blowing up on TikTok, and how you can try it safely.
The TikTok Fix: Turn Off Background App Refresh + Airdrop + Raise to Wake
This combo of settings, discovered and shared by @TechFixJess (with over 2 million views), has been helping iPhone users cool their devices down within minutes, without any third-party apps or risky tweaks. Here’s the step-by-step guide:
1. Turn Off Background App Refresh:
Go to Settings > General > Background App Refresh > Set it to
"Off."
This prevents apps from constantly updating in the background, reducing
processor and battery load.
2. Disable Airdrop When Not In Use:
Swipe down from the top right > Long press the network box > Airdrop >
Set to “Receiving Off.”
Airdrop constantly scans nearby devices, draining power and heating your phone
even if you’re not using it.
3. Switch Off 'Raise to Wake':
Settings > Display & Brightness > Toggle off “Raise to Wake.”
Every time you move your phone, the screen lights up, which accelerates heat
buildup, especially in hot weather.
Why This Fix Works
These features are convenient, but they use constant CPU cycles and keep parts
of your device awake, even when idle. Disabling them reduces background
activity, letting your iPhone “rest” and cool naturally. Combined, they can
lower surface temperature by 4–6°C within 5–10 minutes according to multiple
user tests.
Bonus Tip: Use Low Power Mode
Low Power Mode throttles performance slightly but helps manage overheating and
battery drain. Go to Settings > Battery > Enable “Low Power Mode” when
your phone feels hot.
Warning: What NOT to Do
Never put your iPhone in the freezer or under cold water, as seen in some
irresponsible TikToks. Sudden temperature shifts can damage internal components
and even crack the screen from thermal stress.
Overheating iPhones are a real problem, but the fix doesn’t have to be complicated. This TikTok-approved method is quick, reversible, and genuinely helpful for keeping your device cool during hot days, gaming sessions, or heavy multitasking.
