Fix: Charging Paused: Battery Temperature Too Low

As hard as it may be for the average Android user to believe, some Samsung smartphones actually deny the user the ability to charge the device due to the battery being ‘too cold’. Samsung smartphones almost always come with Li-ion batteries, and these batteries only deny a charge if their core temperature drops below 4°C. However, numerous Samsung smartphones, particularly the Samsung Galaxy S4 and the Samsung Galaxy S4 Active, have been noted to stop charging and display a message that says ‘Charging paused: Battery temperature too low,’ regardless of their batteries’ core temperatures.

It appears that the culprit behind Samsung smartphones sometimes believing that the core temperature of their batteries is below 4°C, even when they are in tropical areas, is a faulty thermistor that reads the battery’s temperature as either too high or too low, causing the charging process to pause. Not being able to charge one’s smartphone, a device integral to the average person’s everyday life, is definitely not something a person can tolerate. The following steps can be utilized by individuals to prevent their Android devices from halting charging and displaying the “Charging paused: Battery temperature too low” error message:

1. The thermistor is located in the USB charging board (shown in the image above) of most Android devices and almost all Samsung devices. That is why the first step a person needs to complete is to buy a new USB charging board for their respective device.
2. Carefully open the device.
3. Disconnect the device’s USB charging board.
4. Install the new USB charging board and connect it.
5. Reassemble the device carefully and boot it up.

If a person happens to have a valid warranty for their device, they should simply claim the warranty and send the device to the manufacturer to be fixed. In the event that a person’s device does not have any warranty and they do not want to take the risk of opening their device, a workaround they can use is to purchase an extra battery kit and charge one battery externally while using the other one. Another viable workaround for the “Charging paused: Battery temperature too low” problem is charging the device while it is turned off, which seems to work on most devices that suffer from the issue but sacrifices device uptime.
