Ok so I did testing on this app to see how much battery is saved with 50 percent of the pixels off. Here are my results: With 50 percent of pixels off I got 28 minutes and 27 seconds on a youtube video where the battery dropped 5 percent. For the same video with no pixels off I got 29 minutes and 31 seconds where the battery also dropped 5 percent!!! The test was done under the same exact conditions. The phone is a Pixel 2 XL. This app does not work! Just so you people understand what I do for a living, I am a scientist that tests different drugs and their effect on physiology. I do testing like this for a living. I am uninstalling this app since it drains the battery.
I liked it. It's a must try if your display is AMOLED. Free features were cool BUT I decided to pay because I just loved at first sight. But I'm confused about night mode, turning the screen red saves battery? 😐 The other features like black wallpaper if below certain battery level is excellent, and the ability to turn off the display (or making it black) when the phone is laying on it's screen is just what I wanted. Sadly it won't start on boot in my ZUK Z2 Pro (even if configured in the security app settings and permissions)
I had high hopes for this, even donated. The concept makes sense. Unfortunately, I think the process itself is draining the battery more than any savings it provides, at least on older OLED devices. I have found this to be the case with "screen off clock/displays" as well. What a cool idea though.
This is brilliant. Simply the most brilliant battery saving idea. I thought about something sort of like this, but I didn't think anyone would actually do it. Have not used it in tandem with Pokemon GO yet, but in theory it should solve one of the quickest battery draining quirks of the game - just rendering the whole thing. We will see.
These types of apps are particularly useful and this one in particular has a very good and easy-to-use interface. Aside from obvious benefit to your battery, it also helped prevent screen burn-in which is a major reason that I use it. In my experience that can be especially problematic on the keypad that displays when you type in text messages which may be present on your screen, static, for many many many many many hours, a sizable percentage of the entire lifespan of the device
Very useful. A few small issues though. It seems it won't stay running when it gets killed by Android, or when I slide it off in the recent apps list. It may also crash with a unable to start service error. Also sometimes while changing the settings, it may cause the system to freeze and reboot.
