Should we even register a wake lock for correspondence games? There is no pressure to immediately show opponent moves.

I considered that and figured there might be some people who open up their correspondence games on their phones and think about the move for some amount of time. The screen going dim may be distracting in that situation.

I understand, but I don't think it should be done unless you're playing a real time game. Wake lock is a terrible practice unless there's some important foreground or background activity to sustain, and a correspondence chess game does not qualify. We don't ask for wake lock on puzzles either. It's the same as playing connections or crossword, users might stare at that too but you don't see nytimes disabling screen savers on them.

we could get some pushback from correspondence players who are used to the old behavior (i am one of them), but i think this is the right call. thanks.
