While camping in the boonies I needed to charge my cell phone but also needed to use it at the same time (poor time management) to take photos, etc. While doing so I experienced phone temperatures like never before and it even caused my phone to power down twice. I may be able to contribute some of the problem to my phone being 4 years old and maybe the battery is getting weak but I have not experienced the same issues while plugged into a standard 2.4 amp wall outlet with same phone battery remaining level in both situations.
I have tried to replicate it with the wall charger this past week and it doesn’t get over 100F
I have no idea what temp it hit but it was quite warm in my hands, probably around +120F or +50C
My phone only charges at approx 900 mAh and tests with the battery pack showed similar charge rates.
FYI, this is not an Anker battery pack but a 10000 mAh pack with similar specs.
Has anyone had this type of issue while charging with an external battery or is this normal?
That makes sense. I was in airplane mode at the time but found es file explorer app had recently updated and was consuming lots of battery so I removed it and that could be why I could not replicate the problem.
It is most likely an issue with using your phone while charging it in direct sunlight & body heat. My phone occasionally overheats and restarts when I’m downloading to many torrents simultaneously. Even when charging inside out of direct sunlight in ideal conditions. I could easily Rectify this problem by limiting the number of Torrents downloading simultaneously but I prefer performance and speed.
I was in airplane mode at the time so no torrents. definitely was hot outside that day and the fact I was using the camera while charging coupled with ES file explorer was likely culprit. haven’t had the problem since I removed ES file explorer.
I know from personal experience that even doing menial tasks on your phone in combination with sunlight can make the device very hot. I don’t know if you have a removable battery but next time this becomes an issue please let me know if the battery becomes hot as well as the device. Hot battery bad Hot phone normal. I have experience similar issues and thought it was my battery but when I took everything apart the phone itself was extremely hot but the Battery was only slightly warm.
My device is a Samsung Note 3 upgraded to Android 7.1 with a new Anker battery.
