Device battery expanded when running automation 24/7

[shaychosen]

Hi,
In my automation framework I’m running tests for an app that use a lot of recording, taking photos and play videos.
It runs on both platforms IOS and Android using selenium grid and appium.
The setup for IOS is one device connected to one mac air (5 in total, no grid) and for android is 5 devices connected to mac mini with a usb hub (15 devises on 3 mac mini with grid).
recently I start running the tests 24/7 and after few days I saw that in one of my Android devices the battery expanded and break the device (Motorola device).
One week later it happened to another device (Motorola again) and now It happened on LG G3 this time.
This is happening only with Android devices and not with any of my IOS devices.
Is anybody face same issue? what I can do prevent this to happen?
Thanks.

If you have a warranty, get them replaced with better quality batteries. You didn't modify the operating system nor the hardware, so this use case should be covered.

Otherwise, this is a rather unusual problem I've seen involving automation. Most issues I've come across are related to software.

i suggest you use the command 'add reboot' to reboot the devices after a test completed. I also encountered the same problem.

sorry , adb reboot ,not add reboot

Try using a fan. Constant use will make the phones constantly hot and heat is the enemy to a phone's battery.
