All of a sudden my Fairphone 3 with e/OS is getting extremely hot while charging. It gives audio warning signs.
I read this could be due to a weak 4G Signal. I do have a problems with the 4G signal since the last update.
I have also a FP3, but no problems with signals (1.11-s-20230511288805-dev-FP3). If you try to switch off mobile data, and only use Wi-Fi, does it get hot also?
Thank you @fab. I had a problem with the signal before but then it disappeared after an update. After the latest update it was back again. That is why I thought it was related. I don’t use wifi only lan connection I will try charging with 4G off and see what happens.
Thank you @aibd I did not change the charger. This morning I charged it again without a problem.
Wonder what triggers the warming. Could it be the weak signal because of which the phones has to use more power to get a good signal?
I guess I may have misled by saying “in the background” as there may be unknown systems apps running in the background. I really meant running apps …
… from the Navigation bar, press the Recents icon (rectangular). All running apps will now show – swipe the display to the right, to reveal Clear all.
So my proposal was to check if charging with certain apps running is different from charging having tapped Clear all to “Close all running apps”.
Thank you vary much. I shut down all open apps. Gonna test now to see what happens. Still the 4G in going in and out of connection rather strange isn’t it?
In Settings > Mobile network > Preferred network type … what options are open to you ? Are you able to specify “not 4G” – is there an option which will work ?
In your place I would consider contacting your carrier and asking them if they could try to resend your APN direct to your device (in case they are being corrupted in some unusual way by /e/OS updates).
I have called them and they advised an APN reset. This seems to work for the moment. Keeping my fingers crossed. Thank you for your help. Have a wonderful day.
