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.
Absolutely, there’s no good reason not to. GoPro’s manage to be waterproof and yet still have removeable batteries.
Phone manufacturers are bastards though, and they know that more people will just replace their phone when the battery wears out rather than go through the hassle of replacing the battery, a hassle that is by design.
