[Q] Xperia Z and CM 11 - Am missing "Stamina"

Heya,

Im a total phone n00b, but was sick of Sony's bloated updates so did some googling and successfully installed CM11 on my Xperia Z (went from Sony's official 4.3 build)

Im greatly prefering the nightly CM11 builds, they are more stable than Sony's 4.3 update Before someone says, I do realise this isnt released as stable software, but Im fine with that, it works really well. Im just looking for ways work around some of the issues

I am having a couple of problems, I would ask in the development forum but dont have the permission to do so, so hopefully someone can help me here.


#1 Im getting Music stuttering/artifacts when playing MP3's. It seems to be a common thing on the Z at the moment.. I did some playing and the only fix I have found is running Android Tuner with the CPU setting at performance, which plays smoothly without any issue. None of the other less power hungry settings seem to be able to play MP3's smoothly.

#2 Battery life sucks. I get about 6 hours of average use now. On the official 4.2 software Id get an easy 10 hours with the same use.

Im guessing my issues are very much one and the same thing. The sony builds come with "Stamina" the app that controls clock speeds etc and greatly increases battery life.

Ive downloaded Android Tuner, and DU Battery saver, in an effort to try and reproduce what Stamina was doing, but I cant find the combination of settings that work.

Does anyone have any ideas on what settings to run? A single app that does what Stamina does? Any other ideas on how to get my phone fast enough to play MP3s, without requiring a diesel generator towed behind it for the hourly recharge would be great



Thanks!

Not to diss cyanogenmod or anything but currently nightlies are a bit iffy, may work well for you but may I suggest for the time being you switch to beanstalk ROM you will get superior battery life, performance and a a lot more features it should also fix audio as I've experienced excellent audio quality with the ROM.

A very got alternative to Stamina is Greenify. It hibernates apps when you don't use them. It is basically the same thing Stamina does. The only thing you won't have is that internet connection won't turn off when you switch off your screen. But with Tasker or Llama you can create a profile to change to 2G when turning off screen and switch back to 3G or even Lte when turning screen on.

Because Xperia Z's CyanogenMod11 default CPU voltage is higher than the Sony official system, only to be saving by reducing the CPU voltage. But CyanogenMod11 kernel does not support CPU voltage drop, third-party kernel "MEOW-kernel.v1.12.17-kitkat" currently does not support the CPU voltage drop. To power saving can only wait "MEOW-kernel" support a voltage drop.

Use the Snapdragon Battery Guru app. It's specially designed for Snapdragon processors by Qualcomm. It's does a pretty similar job to what Stamina Mode does.

Cheers people,

Have been running Beanstalk for a few days, its definetly less greedy than the Nightly CM11 and is playing music fine with no tweaking needed. Just installed snapdragon battery guru too.


Thanks heaps!
