My Hi9 plus(red button) consumes battery rapidly(0.8% / 1h) during sleep. Similar reports are found on the web by searching google.
I used to think this is the performance of this tablet, but the other day I noticed that the device never enter to deep-sleep during screen-off. In other words, CPU is always on. Some battery monitor apps such as AccuBattery reports that.
Is this an intended behavior? I did factory reset, but this behavior did not change.
I never use the suspension unless it is going to be for a very short period of time, but, to what you comment, I think that, when having LTE with calls, the behavior of the tablet should be the same as that of a cellphone, not never go to deep sleep, and should consume just as a cell phone does in the same situation Then I will see if in the system options there is something that can modify this behavior when no SIM card is used, but with it, I think it should behave as described
