I do lots of testing of apps in real phones, not emulators.
The thing is that the phones must be connected to the PC all day. Because of this, phones battery get swollen and I have to buy phones regularly.
Do you know any android phone which can be connected and on all day all week without getting swollen after a time?
Must be real phones, emulators are descarted.
On both my iPhone 7 and Pixel 4a I saw a message pop up after having them plugged in consistently for a week something to the effect of “battery saver engaged” where it wouldn’t charge anymore for the health of the battery.
