[APP][4.1+] Save your battery power with Pixel Battery Saver (Pixel Overlay App)

Hi!

At the beggining - I'm sorry if you won't understand something. English isn't my main language, I still learn.


In some smartphones with AMOLED screen (such as Samsung Galaxy S4) black pixel = turned off pixel.

I've always been irritated because of the fact that our batteries aren't too great, but phone producers still produce their phones with hiper-resolution, which practically we cannot even see.
I have invented something, that later I turned to real app.

I call it Pixel Battery Saver, because it displays some kind of totally black mesh on the screen (you can change its density), so at least half of the pixels (or more) are turned off (so the screen consumes less energy!), while you are still able to read anything on your screen.


If you still don't understand, just take a look at the screenshots.

I've already created this app.
You may download and test it for free,
but if you really appreciate my work - I would be grateful for every donation (every single dollar would be helpful).


Let me know if you found any annoying bug or misspelling. This is my very first app - I still learn

FAQ:

What do I need this for?
- Imagine this situation - your battery level is really low, but you have to search for something important on the Internet. Making the brightness lower often isn't enough. That's when you would need my app - to turn off some count of pixels.

There are lots of apps that dim the screen...?
- This app works different. It doesn't overlay your screen with transparent image (but there is such option in premium version if you need it too). It overlays your screen with totally black screen, which makes some count of pixels off, to prevent them from consuming battery.

Do I really need AMOLED screen?
- The best results you can get right with AMOLED screen, where black pixel means turned off pixel. However, even in other type screens black pixels are saving some battery, so it's just worth to check.

In battery stats I can see that this app consumes a lot of energy. Why?
- Don't look at the stats, look at the real battery consumption. Probably, Android Battery Stats app "thinks", that this app display an image on the screen all the time, because of what it shows an information about consuming energy. In fact, this app turns OFF the pixels (in AMOLED screens with this function), so it SAVES that energy, not consumes.

When the mesh is on, I am unable to install apps (Install button is disabled). WTH?
- That's because of the Android Security. In premium version of Pixel Battery Saver I added an option to bypass this protection. In this free version you can simply turn off the app (by clicking "Turn off" button in Settings window) before installing any app and then turn on it again.




Density of the mesh that I recommend is "High".

Ok guys, it's time to share my work with you.
Be aware that this app is tested ONLY on Glaxy S4.

Feel free to test if it really saves the battery :good:
And remember! It's my very first Android app.

@up - tell me where's the point of buying high-end smartphone and then constantly undervolting it? If I'd need a lower-spec one I'd buy it.

My idea is to save the battery when we need it, for example, when our battery level is really low and we need to search for something important in the Web.

Don't get my thread as a question "what do you think".

The main-concept app is ready, I'm making it more functional now and I will release the alpha version as soon as possible to let the people who are interested in it test it and help me decide if it really works as I expect.

By the way - I tried to learn Android developing from 4 years with totally NO effect. Now, finally I understand more and more, so this app is also my big "Hello world" in Android
