[LeEco Le Pro3 ROMs, Kernels, Recoveries, & Other D] frxxl@gmx.de:
(Highly subjective) kernel comparison - 20170423, standard kernel vs. eas 2.6

Since I did not get many replies whether any1 else tried to "somehow structured / scientifically" compare the kernels, I did this over the last week, focussing on battery life. First, 2 days with standard kernel, rest of the week on eas.

Although I think that I use my phone quite consistently, of course these weren't lab conditions and I know that my findings do not necessarily apply to everyone else. Still, since it is so little effort (empty the folder "flashafterupdate" to stay on standard kernel, flash eas whenever you like) - maybe I can raise some curiosity here to try this, too :).

Getting straight to the point: It is very close, maybe even inside the margin of error, but in my experience, with standard kernel the phone has less standby drain than eas and therefore lasts longer. For me the "threshold" at around 11 in the evening is at around 65 % - if bat is higher, it should last the next day and I dont (need to) charge. Eas never got me there. But standard comes with 2 setbacks, second is big. First is that bat stats do not reset after full recharge. Btw, also not in now current 20170430 build. Not important. But second: Phone did not recharge after shutting down from drained battery, instead started turning on and off which was a happy surprise in the morning. Booted to TWRP (which did not even show a battery percentage value ;), charged to 20 %, flashed eas and finished charging then. But standard does charge when phone is running normally and I did not fully drain on eas kernel cause I need my phone to work in the morning, so I don't know if only standard kernel is to blame.

One more thing: Both kernels are fast and stable, geekbench both at +1800 single core and +4400 multicore, no crashes, glitches, bugs (beside abovementioned) whatsoever in daily usage. This rom is the only one i used for more than 3 weeks in 3 months of using this phone, trying almost all other roms on xda (of course not all versions of all turbo roms, would be impossible)... So thanks again darkobas, it absolutely is a great rom.

Alright, moving forward:

My setup / usage:

-2 simcards from different providers, one just for LTE data.

-Smartwatch (Moto 360) with android wear, keeping bluetooth on, and when I use my car, it connects to handsfree set.

-whatsapp, telegram and facebook

-emails collected via push from 2 accounts with k-mail

-all photos backed up on onedrive instantly everywhere

-Avast security pro in background all the time

-basically all google syncing stuff, data backup, calendar, contacts, movies, music etc.

The phone's day starts at 7 and ends at midnight, sot averages around 1,5 hours per day (usually +- 0,5), mainly for abovementioned apps, news, and occasional "surfing" with chrome. Sometimes ebay, youtube etc., very little gaming, no "advanced" stuff (have my pc for that :). At night, phone is in flight mode while being charged (or not if battery life is good enough :).

I attached some screenshots, 1 & 2 on the evening on day 2 before the phone died on me, 3 & 4 after one normal day on eas. I know that sot is little below average in 1/2 and little above in 3/4, but I covered several more days on eas and even with less sot, I always endet below 60 % at the end of the day. So a very, very comfortable situation for one day, but not for 2.

If others share my "findings", that would be kind of great (I think) because if there is no significant difference between the kernels, maybe it is possible to "enforce" it? One of the kernels really strongly focussing on battery life, the other one for mixed usage or even strong performance? I'm not talking about zero and hero here, just more noticeable differences. For my purpose, just as an example, it wouldn't matter if, while in standby, whatsapp messages were not received instantly but after 2-3 minutes, emails after 10 or more.... I don't know if thats done in the kernel, just thinking out loud.
