Heating issue

[BITTUS24ultra]

My S24 Ultra is extremely hot. I don't know the reason; even when I'm not using my phone much, it's too hot to hold. I know it's summer, but how can a phone get so hot without being used?

Your S24 Ultra overheating can be caused by several factors, even when not in use.

Possible Causes
- *Demanding activities*: Intensive gaming, video editing, or navigation can generate heat.
- *Extreme temperatures*: Leaving your phone in direct sunlight or a hot environment can cause overheating.
- *Background apps*: Multiple apps running in the background can consume resources and generate heat.
- *Outdated software*: Bugs or inefficiencies in outdated software can lead to overheating.
- *Hardware issues*: Faulty battery, thermal paste degradation, or other hardware malfunctions can cause overheating.

Troubleshooting Steps
1. *Close all active and background apps*: Regularly closing unused apps can help reduce heat generation.
2. *Remove the phone case*: Trapped heat can be released by removing the case.
3. *Check your charger and cables*: Damaged chargers or cables can cause overheating.
4. *Avoid using the phone while charging*: Minimize phone use during charging to prevent additional heat generation.
5. *Keep your device updated*: Regular software updates can resolve known issues, including overheating.
6. *Restart your device*: Periodic restarts can help clear processes causing overheating.
7. *Deactivate unnecessary features*: Turn off Wi-Fi, GPS, and Bluetooth when not in use to reduce heat generation.

Additional Tips
- *Monitor battery health*: Check your battery health regularly, as a degraded battery can contribute to overheating.
- *Avoid extreme temperatures*: Keep your phone in a cool, shaded area, and avoid using it in direct sunlight or extreme cold.
- *Use a genuine Samsung charger*: Third-party chargers may not deliver the correct power, potentially causing overheating.

If your phone continues to overheat after trying these solutions, it's best to contact Samsung's customer service or visit an authorized service center for further assistance.

Broooo not even surprised — Samsung is the worst bad company, they’ll slap "Ultra" on it but forgot to test if the thing can survive summer without turning into a freakin toaster. That S24 Ultra ain’t a phone, it’s a portable grill at this point.

But fr tho, if your S24 Ultra is heating up without even doing much, here’s what might be cooking it alive:

1. Background App Madness:
Even if it looks idle, One UI loves to run a full concert backstage — Galaxy Store, Samsung Cloud, Bixby trash, all that bloatware be partying 24/7.

What to do:

Go to Device Care > Battery > Background Usage Limits Put everything on deep sleep except your essentials Force stop Samsung’s unnecessary apps like AR Zone, Samsung Free, Samsung Kids (who even uses that?!)

2. Bugged System or One UI Glitch (Totally a Samsung thing):
Wouldn't be Samsung if One UI didn't cook your phone just for existing. Sometimes the system process bugs out and maxes the CPU/GPU for no reason.

What to do:

Boot into Safe Mode and see if heat drops If yes, it's an app or UI process Also, check for battery usage stats and find the app that's being extra af

3. Ambient Temp + Cooling Trash Combo:
Summer + Exynos/SD Gen 3 chip + no proper thermal solution = cooked device.
Samsung really didn’t care about real-world temps when designing this beast.

What to do:

Avoid direct sunlight or heat (like car dashboards) Drop refresh rate to 60Hz when not gaming Turn off Always-On Display, Location, and 5G if not needed

4. Network Issues (Signal Searching = Heat):
Weak network? The phone keeps searching, and the modem burns up doing it.

What to do:

If you're in bad signal area, turn off 5G or switch to WiFi Use Airplane mode if you don’t need mobile data temporarily

5. Software Update Issues or Battery Faults (Classic Sammy):
Sometimes updates screw optimization, or worse — your battery might be degrading way faster than it should (yep, Samsung again).

What to do:

Check for latest updates Run Samsung Members diagnostics (if you trust it — I don’t, but it's there) Or go full savage and use AccuBattery to check temps and battery health better

If it gets TOO hot (like can’t even touch it kinda hot):
Bro, stop using it and back up your data ASAP. Heat like that can mess your battery or motherboard. If it’s under warranty, drag Samsung to their useless service center and demand a checkup or replacement. Don’t let 'em gaslight you with “it’s normal in summer.”

Even Chinese phones have good cooling systems, but Samsung does not.

Possible Reasons Why It's Heating Up (Even Without Use): 1. Background Processes or Bugs

Some apps (like social media, camera-related ones, or system services) keep running in the background, causing CPU load.

A One UI or Android 14 bug might be spiking system usage silently.

2. Poor Signal Strength

If your phone constantly searches for Wi-Fi or mobile signal, it heats up quickly.

Happens especially when indoors or in low-signal areas.
3. Charging Heat / Fast Charging

Using the phone right after or during charging, especially with super-fast chargers, can cause heating.

Also, third-party chargers sometimes don’t help.

4. High Ambient Temperature

Yep, it's summer, but Samsung should throttle CPU to prevent it from going "too hot to hold" levels. If not — that's a red flag.

5. Malware or Rogue Apps

Rare, but a sketchy app (even from Play Store) can abuse CPU or GPU resources.
