  • Using the Galaxy Z Flip 3 for extended periods.
  • Using it while charging. 
  • Storing it directly under the sun or other heat sources for a long time.
  • Running multiple or graphics-heavy applications. 
  • Using faulty or counterfeit charging accessories. 
  • Operating under an outdated software version making the phone perform inefficiently.

1. Lower the display’s brightness.

At 1,200 nits of peak brightness, the Galaxy Z Flip 3 sports a brighter display compared to most average phones. This also means it consumes more juice when you set it to high most of the time.

Believe it or not, this can be a big contributing factor in making your phone power-hungry, which results in battery overheating and draining issues. Adjusting it to the lowest workable brightness will effectively extend your phone’s battery life.

  • Swipe down from there to open the quick settings panel.
  • Swipe the brightness bar left/right to adjust.

2. Don’t use bulky phone cases.

The main selling point of heavy-duty phone cases is the superb protection it provides for your handset. If you often go on nail-biting adventures, the feature is heaven-sent.

But heavy-duty phone cases can have a drawback: you’re trading off good ventilation, which protects the inside hardware from overheating, with unnecessary layers of external protection. So if you don’t need it, get rid of the bulky phone case.

3. Don’t use a cheap counterfeit charger.

In general, using fake and unaccredited charging bricks or cables for any phone is ill-advised. More often than not, you can expect counterfeit chargers to be subpar and do more harm than good to your phone’s battery.

We recommend using only supported and Samsung-accredited charging accessories. This should make you sleep better at night. 

4. Turn off unused network services

Wi-Fi, mobile data, Bluetooth, and GPS all consume extra power, especially when used in tandem with other apps. A 5G network connection, for example, will drain your phone’s battery much faster, according to Samsung support.

When not in use, it’s advisable to turn these network services off one by one. Or try Airplane Mode to do it in one fell swoop. 

Follow these steps to turn off network services:

  • Open Settings.
  • Click Connections.
  • Toggle off Wi-Fi, Bluetooth, etc.

Note: Toggling Airplane Mode will temporarily disable all network connections at the same time. 

5. Use power saving mode.

Power saving mode lets you hit two birds with one stone. This feature not only extends your phone’s battery life but also limits certain features and functionality on the device, which means less power consumption and no overheating problem.

If possible, we recommend using this feature often as we think it’s the most effective way to fix overheating issues on Samsung Galaxy Z Flip devices.

Every app that is minimized, running, and using data in the background contributes to your phone’s battery consumption. Running multiple apps also takes up a lot of memory and overworks your processor, which is a common cause of overheating.

Restricting and closing unwanted apps in the background should fix overheating issues on Samsung folding-screen smartphones.

FAQs about Overheating Issues on Samsung Galaxy Z Flip 3

How do I cool down my Samsung Galaxy Z Flip 3?

Turning off the device cools the Samsung Galaxy Z Flip 3 down quickly. This will shut down all the apps and processes that are running and greatly reduce battery consumption.

Does the Samsung Galaxy Z Flip 3 overheat from charging?

Charging shouldn’t overheat your phone as the heat generated by charging is normal and does not affect the battery’s lifespan. However, using your phone while charging will cause it to produce more heat than normal, which can cause overheating.
If you feel your Galaxy device is too hot to touch while charging, then you should disconnect the charger right away. Turn off your phone and once the device has cooled down, start the recharging process again. 

How do I know if my Galaxy Z Flip 3 is overheating?

Reaching temperatures above 95 °F or 35 °C is considered overheating. This is not an ideal condition to use your phone under, and it should be allowed to cool down as soon as possible to prevent further damage to the battery.
Additionally, Samsung Galaxy Z Flip 3 sends a warning message when a particular temperature threshold is reached. After some time, if the phone is still heating up, a second warning is sent, followed by your phone’s automatic shutdown. 

How do I replace the battery of an overheating Galaxy Z Flip 3 phone?

Consult a Samsung technician to have your battery replaced if it’s showing signs of overheating and battery draining issues very often. You can reach out to Samsung Support to book an appointment with your nearest service center.
