The title says it all - AeroInsta has a massive battery drain in both foreground and background.
The likely reason is this logspam that is so much, that it crashes Matlog (my logcat app of choice). This is a longstanding bug that many users experience, regardless of device.
My device is stock Galaxy Note10 Lite on latest A12. It's a good up-to-date mod, probably the best out there but this battery drain makes it unusable...
Here is an extract from the logs I managed to save:
The problem is with requests to FB and Insta servers that are blocked but not removed, nor rate-limited.
