Interesting.
I didn't see anything in the first few days.
I switched to ElementalX after a few days.

Kernel is also the #1 app in my list. However, I have not noticed any unusual drain or general battery concerns so far. I will pay attention if the kernel stays on top of my list even when I'm using other apps more heavily.

Kernel wakelocks go through the kernel but they aren't caused by the kernel. Those are system wakelocks. They can usually be blocked if you are rooted and using a custom kernel but the kernel isn't creating those wakelocks or draining power.

Same here.
When I wifi : on and screen : off, battery gone 5%/h.
fully stock, 8.1, bootloader. no root.

[Q] Stock Kernel vs Franco Kernel

Hi guys, after watching videos on franco kernel, I end up installing it to my N7. After using it for several days, I noticed nothing much changed since the last time I'm using stock kernel. Is there any way that I can install back my stock kernel? or perhaps someone can guide me to use franco kernel effectively. Since my battery life isn't affected much by franco kernel, so I decided to revert back to stock kernel. Hope to receive guide from pro's out there.
Franco kernel has later changes and commits than stock kernel does. Performance and battery life without a doubt should be higher. You can configure the kernel using his premium app called FKU on the app store, or use a third party kernel app. Best of luck.
Seeing a stupid comment on Google Play about an app you love and marking it as "spam". You've done it too.

CM12.1 V18.2 temasek - HELP: Battery Drain issue

Hi guys , i've just flashed my samsung note 3 to CM12.1 and i am experiencing huge battery drain issue.
Any kind souls over here to assist a newbie ?
So sorry to trouble.
Those AOSP ROMs will never give you as pleasing battery backup as TouchWiz based ROMs, but still first thing is, you need to mention what processes are sucking the battery life. Install BBS and mention here.

Use any TouchWiz stock ROM, or at least stock based ROM custom ROM. If you want a full featured ROM go for Arya, if you want a ROM as close to stock as possible then go with Alexender's stock ROM.
In any case, you do need to monitor what app/ processes are creating wakelock via Better Battery Stats.

Root it again and flash a great(SkyHigh) kernel Thats not so hard to do it instead of waiting such a basic advance. Bug or sth like that prevents the device to go 'deep sleep' Good luck~
With stock kernel it will drain the battery ?
Because i know that with a custom kernel will work.

Yes, with stock kernel, there is too much drainage due to not deep sleeping or/and another reason. I have shocked when i realised that(second day after owned) then immediately flashed a kernel. Now ok.

That occurs for some note fives too. Weird, never faced it with other brands. This is the awkward samsung phone ever bought since galaxy s3. Customized and became kool
Im using Audax rom v6.1 , includes fantastic audio mods, air commands, customizable other things. Just great deal for me. If you need advices about kernel, see them in our thread. Thanks.
The Audax 6.1 + Sky High Kernel is the best combo for battery ?

Not just for battery, for all. Check the various synapse options. But I prefer you to try all others(kernel,rom) if you can.
Same here flashed new kernel fixed it

Kernel Wakelocks

This is the first time I have experienced such a high amount of battery drain from the kernel. I have attached the BBS screenshot below. Any suggestions? Running stock rooted. Thanks.
