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

Hey guys, I did a little testing (and I mean little) and here's what I found out.
So I got the screen at maximum brightness and left the screen on with a screenshot I made of the playstore, for about half an hour and then I launched the pixel saver and let that for about half an hour as well. Here's my results. (the battery percentage is directly android's battery)

time-percentage (w/o app)
1:50 - 53%
2:02 - 51%
2:11 - 48%
2:21 - 45%

that would be roughly 8% of the battery in 31 mins.

then with the app on maximum mesh setting

2:22 - 45%
2:31 - 44%
2:43 - 42%
2:51 - 41%
3:01 - 39%

so that would be 6% in 41 mins.

if we were to take just half an hour of both runs (w/ & w/o the app), in about 30 mins, the screen would drain 8%, respectively 4% (with app), so that's basically double the battery, or half the drain. Again, this is a "rough" test, a quick test, just to get a glimpse of how good this app is.

Here's the screenshot: *url * dropbox.com/s/tczkg3u5y4y8sni/max%20payne.png?dl=0 *url*
and pixelated: *url* dropbox.com/s/2fu7qf1ez2w90d1/max%20pixel.png?dl=0 *url*

if you zoom in the pixelated one you can actually see the pixels (I think those are real pixels, I don't know for sure, lol ) and the 2 pixel gap between them.

Hope this helps in any way.

Similar to guky667's post about battery usage, I did my own quick run and here's the summary. What is surprising for me was that Medium density vs Highest density draw ~same battery life. I might do a second round of testing to confirm the mesh density and battery drain.

--- RESULTS ---

Common Assumptions
-Phone in airplane mode
-Screen = Max Brightness
-Screen has Whatsapp chat as the static image (black bg, colorful boxes, bottom grey typing bar, top green/gray bar for contact)

Case 1 = NO FILTER
7:50 = 62%
8:20 = 55%
7% in 30 min OR 14% in 60 min

Case 2 = Gray filter from GS5 UPSM
8:20 = 54%
8:50 = 49%
6% in 30 min OR 12% in 60 min

Case 3 = Pixel Mode (Medium = Usable still, sharpness is gone around edges)
8:50 = 48%
9:20 = 44%
4% in 30 min OR 8% in 60 min

Case 4 = Pixel Mode (Highest = Very pixelated)
9:21 = 44%
9:51 = 40%
4% in 30 min OR 8% in 60 min

--- END of RESULTS ---

--- Retested results ---
Case 3 = Pixel Mode (Medium = Usable still, sharpness is gone around edges)
19:09 = 63%
19:39 = 58%
5% in 30 min OR 10% in 60 min

Case 4 = Pixel Mode (Highest = Very pixelated)
18:39 = 69%
19:09 = 63%
6% in 30 min OR 12% in 60 min
--- End of Test #2 ---
