After 4a and 6a, now is the time for 7a to shine!
Though, is it still in early beta and apparently very few models seem to be affected and there isn’t any word of system update to nuke the battery life on this model. But it goes to show that Google is treating the A series really badly.
Pixel 7 is around $160-180 used right now, that might be a nicer option than the 7a.
Alternatively do the 7a and get a free new battery from Google if it pans out that way…
