I know that Teracube has battery life issues due to a bug and I find myself having to use battery saver on full battery to last. Is there an option to use doze to not have to use battery life while the screen is off?
Apologies for the late reply - missed this topic somehow. Are you still experiencing battery issues after SW6 update? That is not expected at all. Could you confirm how much is your battery lasting?
Clearing the cache partition might be a good first step if you have already updated to SW6.
