========================================
My battery started draining 11 or more percent per hour ( before it was 7 to 8 percent) after i installed 087 version , but i think that may be my device getting old so its draining faster .
I waited for next pie update or stable A10 upgrade ...
After a month of releasing A10 beta 438, i can't resist my self to try a beta version first time. Because there is no sign of releasing stable A10 soon and most users said beta 5 is almost stable and no password issues or data loss .
Yesterday i finally moved from Android 9 pie 087 to Android 10 beta 438.
Believe me this update gives much better battery back up just as i got before almost 8 percent per hour. Using mobile data , YouTube , Facebook and chrome as i did always.
Except sound problem, this rom is better than all the pie version roms.
Look at the screen shots, i removed charger at 97%.
