[Xperia Z Q&A, Help & Troubleshooting] Calvat:
Hello. Since I got my Xperia Z and boot unlocked/rooted, I've always had some sort of 'wakelock' issue with my device, regardless the rom.

Whether it be A to Z, I keep doing what I can - I've had my phone for a while now and I decided, alright - time to go to a custom ROM (I usually used stock variants)- (Using Cyanogen now; I used them on my old phone, loved it.)

The biggest issue sometime ago with this was the Play Store always being a wake lock.

Or it's RILJ.

Brightness.

Not turning on.

Or it's some other thing.

It's really, really, annoying. There's just no end to the wakelocks. However using this CM11, I've nearly hit the perfect point - I'm down to one wakelock, and though I don't think it's severe - it's a wakelock none the less.

AudioMix.

Touch sounds off, no audio on any setting (media, notification, ringtone even) yet it still persists. No sound during games and, still occurs.

But I've played these games for a while and these have only occurred in this rom(s). Now with 4.4, Better Battery Stats now lists WHO is causing it so YAY! But, these never had audiomix wakelocks so this seems to be the ROM or Android Version

I use a program called AppConfig to make sure my screen doesn't turn off or dim during games, and I tried turning Media Volume to 0 with it once and this stopped the audiomix wakelock. Omg! Testing this, turned volume up, played for a short while, turned it back on and restarted phone. AudioMix.

It only worked once, though. I don't want to always have no sound, just when I turn sound off - I want the sound actually off, not AudioMix wakelocks.

My guess is the ROM is consuming battery because it thinks there's audio, when there isn't.

Currently using...

Version:

Android 4.4.2

Kernel:

inected_@mint-qiana #1

Build:

cm_yuga-userdebug 4.42 KVT49L e743ec3f57 test-keys

And before you say, 'that's out dated now!', this has happened through various CM11 roms and stuff. I've tried a few now, I've just found this one the most wakelock free / stable so far.

I figure it's an issue with 4.4, but -- It's still an issue !! I've googled it and looked at multiple threads and there's always the same answers, but no one mentioned what I did - About an application forcing no sound, disabling the wakelock. So perhaps this could have some theories developed as to why it exists...?

========

My other question is... I've looked at some Auto Brightness settings in the past, but no one has any listed for this latest Cyanogen style of brightness.

What Auto Brightness does everyone use?

Currently I have....

0 Lux: 0%
3 Lux: 0%
6 Lux: 5%
12 Lux: 11%
19 Lux: 15%
25 Lux: 18%
50 Lux: 18%
100 Lux: 18%
150 Lux: 23%
220 Lux: 26%
280 Lux: 31%
320 Lux: 36%
360 Lux: 43%
420 Lux: 46%
480 Lux: 47%
650 Lux: 51%
700 Lux: 51%
750 Lux: 56%
800 Lux: 58%
900 Lux: 60%
930 Lux: 60%
960 Lux: 66%
999 Lux: 67%
1000 Lux: 71%
1520 / Infinite Lux: 100%

I saw a .pdf document about lux values and how much brightness you should have and stuff, but I don't think it was intended for phone use. It looked more like a university study, but I lost the page ><

I tinker with it when I can, trying to get it perfect. But it could definitely still use some tinkering! Wondering what everyone else uses - So if you have any advice or settings I coulld try out, that'd be great thanks!
