LeEco L2 significant battery drop with "airplane" mode

Hello ! Fantastic work. Just a feedback

Problem : The night, when “airplane” mode is on, i notice a recurrent battery drop by 20% (approximately).

After a test, when “airplane mode” is on, “Radio mobile” drops the battery (it uses approx. 15% in 4H). During the test : screen turned off and all recent apps closed.
=> Screenshot: GSam Battery, airplane between 5h - 9H am.

Thanks for rising this issue. I see that you also created an issue on gitlab for this. Thanks for that too, since gitlab is better suited for keeping track of such problems than the forum.

For information, with Oreo (Pi/e/ ROM build by @andrelam : https://community.e.foundation/t/pi-e-test-rom-for-the-leeco-2s/4484), the problem is solved.

Thanks for the update @TheMajorTom good to hear the issue is resolved. Just one correction the link is a test Pi/e/ ROM build by @andrelam.
