Like the venu, the venu sq requires burn in protection, so for "always on" watchfaces, in low power mode, there are things you must consider:
- No more than 10% screen pixels can be on
- No pixel can be on longer than 3 mins
You can see this in the sim if you test in low power mode, and there are things like the "heat map" to help.
I just wanted to mention it, as like the venu, it's not like other devices when it comes to low power. It also doesn't support "1hz" ( no calls to onPartialUpdate())
Battery wise, the more black on your screen, the better (unlike MIP devices)
See the section on AMOLED here. The venu sq is LCD, but things are similar:
