Please tell us some basic information before asking for help:
Model Name: 601kl
Firmware Version: A10,438

Frequency of Occurrence:
APP Name & APP Version (If your issue relates to the app): Android pie 087 version is a laggy and battery eater
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
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%.
