Temperature too high or low is a result of a defect in the temperature sensor (themistor) in a mobile phone's battery, or the thermistor present in the charging/sub board, and in some other cases, it is an indication that your mobile phone's PCB is old and damaged. Rare scenario is when it comes up because of a short on the circuit.

Temperature too high or low is a result of a defect in the temperature sensor (themistor) in a mobile phone's battery, or the thermistor present in the charging/sub board, and in some other cases, it is an indication that your mobile phone's PCB is old and damaged. Rare scenario is when it comes up because of a short on the circuit.
CAUSES OF TEMPERATURE TOO HIGH OR TOO LOW IN MOBILE PHONES:
1)Bad battery.
2)Poor communication between the BSI or BTEMP points on the battery connector and its respective control component on the circuit.
3)Bad sub-board or charging panel.
4)Bad PCB as in the case of some Samsung phones.
5)Bad Thermistor.

SOLUTION TO TEMPERATURE TOO HIGH OR TOO LOW IN MOBILE PHONES:
1)Get a replacement battery :
This is always the very first step you should take whenever you're faced with a challenge of “temperature too low or too high” when the phone's temperature is not actually low or high. So many phones come up with this “pop up” simply as a result of the malfunctioning of the battery's temperature sensor. This communicates with the phone and commands it to shut down or give a warning pop up message. Changing this battery to a New and original one helps solve the case. In a case where it doesn't, read below to get more info.
2)Establish and ensure there is a good and efficient communication between the BSI/BTEMP points on the battery connector and its respective control component on the circuit:
A BSI (Battery Status Indicator) point is the point on a phone's battery connector that conveys the battery's information to the phone. The BSI point is the one that tells your phone the current voltage the battery currently holds, which your mobile phone will translate to current battery percentage. The BTEMP, which is a part of the BSI, but separated in some phone models, reads the battery's current temperature, and conveys it to the phone. Now, if there's poor communication between the BSI or BTEMP point on your battery and on your phone, there will definitely be a misleading message, in which one of them is that pop up “temperature too low”, “temperature too high”. The poor communication could be as a result of a bad/obscured battery connector plugin, or a damaged/shorted/open line between the middle points of the battery connector and the respective circuit component which regulates it.
•First step is to completely change the battery connector if you notice any form of rust or dirt or obscuration.
•Second step is to check the BSI point and its IC component for continuity (this is done by using a multimeter). In a case where the BSI signifies continuity with its circuit's component, it means the line is not broken and we move onto the next step. But in a case where it does not indicate continuity, get the mobile phone's schematic diagram and jumper the BSI/BTEMP to its exact component. This has worked for me many times.
3)Get a replacement charging board/sub board:
Samsung, a South Korean tech giant, produces its mobile phones with many of them having their thermistor on the charging board. If you have tried the above steps and they don't seem to work out, change that phone's charging/sub board. This works for Samsung and Huawei phones which display Temperature Too Hot or Too Low message when it is not actually hot or low. It is definitely deduced the message pops up because of the damaged thermistor on the charging board.
4)Replace the old board to a new one:
In some other cases, some boards get damaged to the extent that whenever the phone is turned on, the board gets too hot, the temperature sensor(thermistor) notices this and turns off the phone. If you're faced with such case, consider getting a replacement board or PCB. But there's something you can try, You can try tracing out the circuit component that is getting hot, then you remove and replace.
N.B : You can trace the exact hot IC component by applying soldering paste or freeze spray onto the section that gets hottest first, whichever IC that melts the paste/spray fastest is the one responsible for the board's overheating.
Also you should note this problem may at times be caused by a software glitch, it pays to run a factory reset when this is suspected.
You can also feel free to reach out to us via email or comments if all of these doesn't work out for you.
I wish you Goodluck.
You guys are good,this is my first time reading one of your articles and it is very......,,,
