I purchased a Huawei Mate 8 a few weeks ago. At first, Aquamail was running perfectly.
Two nights ago, Huawei pushed an android update to my phone. Since then, Aquamail does not sync automatically. That is -- I go to Accounts, and I see that the last update time was hours ago. (I think it's not a network issue. If Aquamail tries to sync, there is a red ! and the time of the last successful sync, but in my case, there is no ! -- it appears that it isn't even trying to sync. I've also had the phone open at sync time, and there's no icon in the notification panel.)
I've just spent the last half-hour checking every battery-related setting I can find.
- Aquamail is set as a "protected app"
- Under Settings > Advanced settings > Battery manager > Power usage firewall, Aquamail is set to "Keep awake." Underneath that setting, "system wake up," "app auto-launch" and "keep running after screen off" are all ON.
- System setting "Close excessively power-intensive apps" is turned OFF
- System settings "Keep WLAN on when sleeping" and "keep mobile data on when sleeping" are both ON
I'm quite sure the system update changed something that Aquamail doesn't like.
