Hey EMUI Users,
If you are a Smartphone enthusiast, you might already have known the mechanism behind "Always on Display" and why it is used but if you don't really know about it, let me explain:
"Always on Display is a feature that comes mostly with Premium range Smartphones (including Huawei Smartphones) which enables you to keep your screen on all the time"
Now the question is: "Why would anyone want to turn on their Smartphone Screen all the time? Won't it empty your battery very quickly?"
There are 2 Parts of this questions, the first one is Why would anyone want to Turn on their Smartphone Screen all the time?
The answer to this question is fairly simple, some people don't like to pickup and activate their Smartphone screens to check if they received any new messages, emails and Missed Calls.
Having a screen that let's you know all this information but not too much information is a good thing right?
That is the reason where Always on Display or AOD comes to the rescue as it enables you to see if you have any new notifications so that you might not get distracted all the time by turning on your screen again and again.
Now comes the second part "Turning on the Always on Display can drain your batter very quickly?"
The answer to this question is a bit tricky as although turning on your Smartphone screen for long periods of time does consumes lot of battery but if your Smartphone has an OLED display, it really brings down the battery usages down because it specifically turns on the pixels that are required and the Always On Display takes benefit of this scenario and therefore only turns on essential pixel on your Screen instead of the whole screen to minimize battery usage
How to enable Always on Display on your Smartphone?
First of all you have to make sure that your Huawei Smartphone does contain this feature and contains and OLED display as well.
After confirming these 2 things:
On EMUI 10.0
Go to Settings-> Home screen & wallpaper -> Always On Display
