This comprehensive guide explores the root causes of Samsung A35 heating issues and provides effective solutions to keep your device running cool and efficient.
Samsung A35 Heating Issue Fix: Complete Guide to Stop Overheating
Understanding Samsung A35 Heating Issues
The Samsung Galaxy A35 5G is a powerful mid-range smartphone, but like many electronic devices, it can experience heating problems under certain conditions. Based on user reports from Samsung community forums, the device tends to overheat during various activities including social media browsing, gaming, video streaming, and even during basic tasks like web browsing or charging.
Many users have reported that their A35 devices become excessively warm during normal operations, with some noting that the upper part of the screen becomes particularly hot during use. One user described the device heating “to the point it starts to burn my fingers” during everyday tasks 3. Another user reported heating issues specifically after updating to One UI 7, suggesting that software changes can significantly impact thermal performance.
It’s important to understand that some warmth during use is normal, especially when performing processor-intensive tasks or charging. However, when the device becomes uncomfortably hot to touch or the heat affects performance, it indicates an issue that needs addressing. Samsung itself acknowledges that devices may temporarily generate heat under certain circumstances, though excessive heating may require intervention.
Is there a heating issue in the Samsung A35 5G?
Yes — multiple user reports confirm that Samsung A35 5G experiences heating issues. Key points:
- Many users say the heating problem is noticeable even during light tasks (social media, camera, video).
- The update to One UI 6.1 / 7 has been cited as making the issue worse for some.
- Some reports say that the modem/5G component contributes: when 5G is active, or weak signal, the device works harder to maintain connection, raising heat.
- Samsung support and forums recognize that the device can heat under certain scenarios, but they often consider “warm” to be normal under heavy use; “hot” (uncomfortable, possibly harmful) is not normal.
How to fix Samsung A35 heating issue?
Here are the most effective fixes, both from official sources and from what working users report. Try them in order; sometimes a combination works best.
- Update software / firmware
Always check for the latest One UI / Android updates. Some heating issues are introduced or made worse by bugs, which are often fixed by patches. - Clear cache partition
Old cache can lead to processes misbehaving and consuming more CPU power, which causes heating. To clear: power off → hold Volume Up + Power until recovery menu → choose Clear Cache Partition (not factory reset). - Restart the device regularly
This frees stuck processes, resets temporary glitches. A simple reboot sometimes noticeably lowers temperature. - Close or uninstall heavy background apps
Some apps keep running (background data, location, etc.), or many apps are open. Identify battery-hungry apps via Settings → Battery / Device care → look at apps with high usage. Then disable, uninstall, or force stop them. - Lower screen brightness and refresh rate if adaptive
High brightness is a major heat source. Turn off adaptive brightness, manually choose a lower level. If screen is running at 120 Hz and it has an option, reduce refresh rate. - Limit use of resource-intensive tasks
Gaming, video streaming, especially in high resolution, camera usage for long periods – these push CPU & GPU hard. While these are fine occasionally, continuous usage causes heat building up. Take breaks. - Avoid using the phone while charging
Charging generates heat; using the phone at the same time increases load on battery + CPU → more heat. It’s better to leave device idle while charging. - Check charger and cable quality
Using non-original or low-quality chargers can cause inefficient charging and heating. Prefer Samsung-certified chargers & cables. Also avoid using wireless chargers or fast chargers if device gets too hot. - Remove thick cases or covers temporarily
Some phone cases trap heat. If device heats up significantly, removing case might help dissipate heat. - Reset to factory settings (if other fixes fail)
If after updates, clearing cache, uninstalling apps etc., the heating issue persists, a factory reset can remove any software glitch deeply buried. But back up your data first. - Contact service or hardware check
If heating remains extreme (cannot hold, device warns, battery swelling, etc.), might be hardware fault: battery, thermal paste, faulty sensor, or defective chip. Authorized service centers can diagnose.
How to stop Samsung A35 from overheating?
Beyond fixing existing heating issues, these preventive and “lifestyle” measures help maintain lower operating temperature over time:
- Don’t leave the phone in hot environments (e.g. car on sunny day, under direct sun).
- Avoid placing it on soft surfaces like beds/couches where vents (edges) are blocked.
- Enable Power Saving Mode when you don’t need full performance. Many settings in power saving reduce CPU speed, screen brightness, disable 5G, etc.
- Use WiFi instead of mobile data / 5G when possible (5G can be more power-hungry and cause more heat) especially if signal weak.
- Keep only essential services on (turn off GPS / Bluetooth / NFC unless needed).
- Avoid running too many apps in background; do app cleanup.
- Monitor apps after updates: sometimes new versions have bugs or inefficiencies.
Does the Samsung A35 have a cooling system?
Samsung A35 does not have an active cooling system like a dedicated fan or vapor chamber (which high-end phones sometimes use). But it has:
- Passive cooling via its construction: internal heatsinks, thermal conductivity through materials.
- Thermal throttling: when CPU / GPU / modem get too hot, the system lowers their performance to reduce heat.
- Software-based thermal management: Samsung’s OS monitors temperature, limits performance, adjusts display refresh rate or CPU usage under heavy heat.
- Battery safety mechanisms to prevent overheating damage.
So while there’s no dramatic cooling hardware (fan etc.), there are built-in protections. If heating gets beyond safe levels, the device may warn or shut off to protect itself.
How do I fix my Samsung heating problem?
Here is a concise checklist (step-by-step) to try when you are suffering from overheating on an A35:
| Step | Action |
|---|---|
| 1 | Update your phone software (system & apps) to latest available version. |
| 2 | Restart the phone. |
| 3 | Boot into Safe Mode (if available) to test whether third-party apps are causing issue. If temperature in safe mode is normal, then an app is culprit. |
| 4 | Clear cache partition via recovery. |
| 5 | Identify and close high-CPU apps; uninstall or disable them. |
| 6 | Reduce screen brightness; disable adaptive / high refresh rate if possible. |
| 7 | Avoid gaming / streaming or long camera use in hot or sun-exposed environments. |
| 8 | Avoid using phone while charging; use good quality charger & cable. |
| 9 | Use Power Saving mode or thermal reduction modes if offered in settings. |
| 10 | Remove phone case when device overheats. |
| 11 | If all else fails, back up data and do a factory reset. |
| 12 | If still problem persists (excessive heat, device damage signs), go to Samsung service center for hardware diagnostic. |

Why Does It Happen? (Technical Causes)
Understanding what’s going on under the hood helps avoid misdiagnosis:
- The Exynos 1380 SoC (used in many A35 5G units) is powerful but under load (5G, GPU, multimedia) it can generate significant heat.
- 5G modems consume more power especially if signal is weak, causing processor and radio units to work harder.
- Charging itself, especially fast or adaptive/wireless charging, is a major source of heat.
- Continuous high screen brightness and refresh rates increase power draw and heat.
- Environmental heat: ambient temperature, direct sunlight, using the phone in hot cars or under blankets, etc., exacerbate the issue.
