Well, my overnight battery drain is not as good as I was expecting when looking to my first results!

Over 8 hours, with plane mode on, I've lost 3%. Just for comparison, with another kernel I get 0%!

With normal usage I'm getting slightly higher values too: 2,5 - 3,5%/hour.

Even though, they are better results when compared with latest official GE's build! If I may say, I think there is some place for improvement... :)

I'm still testing it so I'll get to this discussion a little bit later!

Thx Ktoontez, an excellent piece of work and effort... And patience to listen all this 'complaints'... We, as users, are never satisfied!

Lol!

Also on my phone I noticed a massive battery drain with the latest versions. Any solution?
[Galaxy S 4 i9505 Original Android Development] Murthick:
Ktoonsez, you are an absolute genius! With the GE test kernel the battery drain issue is completely fixed (for me anyway). With 04.02 kernel I was getting approx. 1%/hour drain over an 8 hour period overnight. With the test kernel I got 0%/hour drain over an 8 hour period overnight. Went to bed with 84% battery, woke up 8 hours later with 84% battery! Both tests were done under identical conditions apart from the change in kernel, hell, even the room temperature was the same (unintentional), haha. This kernel is now awesome, I've never experienced a 0% battery drop in 8 hours before, crazy. Thanks for all of your continuous hard work, it's really appreciated by me and everyone else!

after work test: 16ma an hour drain, -0.61%

this was with blocking mode on, on silent - but wifi and GPS still active. facebook was logged in, receiving notifications etc.

no unusual power drain at all, this is on par with the best results i've had in the same scenario. logging out of facebook and such would get me my 'best' rate of about -0.4%, based on past testing.

(oh and this was from a 100% charge - so if what others say about it draining faster from full, it'd be lower later)

Thanks to [MENTION=3545504]smeroni68[/MENTION] for talking to [MENTION=4825437]Christopher83[/MENTION] and firguring out that it is the kernel version string length that Antutu can not handle and causes the crash (FC).

Hello,

I figured out lately that I have a quality issue when playing music to external loudspeakers. When the music is quiet, I clearly hear kind of cracks in the sound.

I'm on the google rom for which you develop the kernel.

I have the last kernel version that you share yesterday on the forum (dated April 4th , for the google edition).

I tried to understand and solve without success.

Here is what I know :

- It is not software related (they share the issue)

- No such issue when the playback is done to the loudspeaker of the phone

- It is not related to the speakers and to the cable as there is no issue with another phone (S3)

What I am not sure of :

- I don't know is it a physical issue inside phone. However, I don't think so because when I turn the cable, it makes no different.

Is this a known issue?

Could it be a 'codec'issue ?

Thank you for your help.

Today's report on the battery usage

Current setup consists of latest GE ROM by Danvdh and latest officially available KT kernel (not the test build). KTweaker profile active : Misantherope (a tiiiny biiit slightly modified).

Given the fact that ImageShack is no longer free (*throws rocks*), I've archived all screenshots depicting today's battery drainage in a neat .zip file and posted it here.

Please take a careful look at all of the image files before you draw a conclusion. My conclusion is that it's pretty good, especially since a third of the screen on time was spent in a (not very graphical intensive) game.

Notes

1. I almost never was in an area with less than 70~80% signal strenght. I usually switch to 3G when I leave the house and hop back on to 2G whenever I'm somewhere indoors - it's never on 2G/3G auto.

2. Screen brightness was set to AUTO, which seems to be doing a fairly good job at NOT blinding me.

3. Wi-Fi strenght was at >70% all of the time it's been connected. I'm not sure if there is something similar to the msm_hsic wakelock that kicks in (low 3G signal) for Wi-Fi, but anyway, I'm putting that there.

4. Whenever I was on Wi-Fi, sync was on (one Google account with all the bits there, like Gmail and Chrome, one WhatsApp account).

5. I am not using Greenify - although I should use it for some games that seem to push unwanted notifications.

6. I am using Xposed. More info about that here and here.
