I am not using apps for modifying my phone at deep hardware level, that is just so anti-Linux so it's insane and too simple and boring. Those "powersaving apps" seems to drain more battery than they conserve, and that is the opposite of why we choice to use them, right?

Init.D is the way to go, always funnier with some trial and error.. See script in attached picture!
[Xperia Z Original Android Development] nicestupid89:
haha.ok,this is new to me.thanx
[Xperia Z Original Android Development] Destroyedbeauty:
I am going to tweak this script and tweak Interactive toward more effective battery saving, thus less hi-freq biasing and rather take it down to use the lower frequencies as much as possible.. Uploading modified script later, so other can use it and push XzKernel v14 to the battery saving limit, but still keeping good performance.

I've said this before - the Xperia Z is still an performance beast, with non-optimized powersaving potential. I don't see the whole thing with pushing and adding tweaks and scripts to this device that makes it lose battery from 100 to 0 in 2-3 hours.. :eek:
[Xperia Z Original Android Development] Destroyedbeauty:
Then you are undervolting too low.. Raise voltages a little (+25) on each cpu step and see if you get any improvements.
[Xperia Z Original Android Development] ckyy:
My lowest voltage was -50mV. I'll see if -25mV is any better..which i doubt.

MP-Decision Control

How do I get to the MP-Decision Control screen on V3?
[Xperia Z Original Android Development] ILikeTheWayYouMove2:
In my experience I noticed undervolting too much can cause more battery drain, but too early to report on battery life on v3 yet.
[Xperia Z Original Android Development] mkone:
Get v3 and instal trickster mod :)

Havent got this experience before on any Other kernel. Btw. Antutu stability test was at 93pts on v2.0 so we need to focus on correct combination of kernel settings. (Lots of options)
[Xperia Z Original Android Development] Madala_ZA:
Nice1, I didn;t see the button to access the MP settings. Thanks ;)

after flashing the v3.0 my phone cant read my sdcard even when i tap mount sdcard it just saying safe to remove.

[Xperia Z Original Android Development] DrKrFfXx:
Anyone else has issues with the charging dock using this kernel?

Today I had it on the dock charging and received a call, when I took it off the dock, the device failed to wake up. I got a black screen everytime I tried to wake it up, although the led was still blinking for the missed call. Then I hard reset it and docked ut again. Same thing.

All in all, the kernel feels snappy, it has good undervoltability, although I'm not sure I like the gamma tweaks, for me Iphone's have very cold color reproduction, which is something -or the only thing :P- I like about iPhones, this is totally the opposite, very warm colors, almost sepia.

Will test out battery life through out the day.

Great job for this being still an early release.

And one question: What exactly the zRam option in trickster mod does?
[Xperia Z Original Android Development] ckyy:
Can comfirm the black screen issue. And zram compress 10% of your RAM to act as swap.

All other works fine. If I go screen off from home screen, the phone comes up again without a Problem.
[Xperia Z Original Android Development] ckyy:
Not at all. I'll try to reproduce the "bug" later. Maybe it's just a one time issue. I'll keep you informed.
[Xperia Z Original Android Development] alnikki25k:
That's weird. Anyway, try the next release and let me know. Also, these bugs are a one off thing and generally may not occur again. Hopefully :)

It's related to MP-decision. I'll remove it for now. Intelli-plug seems to be good enough.
[Xperia Z Original Android Development] ILikeTheWayYouMove2:
I also had the issue of screen not waking up, it was after I left the phone for a few hours, the led was working indicating it wasn't off had to hard reset the device but not had the issue since.

And battery life is not so great for me any idea what this could be?

As it says android os is using most of the battery, it's normally not that much

Anyone having some lags in games ?
[Xperia Z Original Android Development] kingrion88:
Nope. But the game i play does not use high quality graphics, so I'm not really sure.

On the other hand, this v14 kernel is amazing. After 11 hours, only 1% drop with -50mv undervolt.

Battery saving-tweaked Interactive is pretty good for battery life if you want that snappy performance but still keeping the freq biasing on the lower CPU range..

For peaple with wifi disconect with screen off, here is a workaround: go to wifi, advanced, and disable Wi-Fi optimisation.

It solved problem for me. Also, this bug is present in every custom Kernel I've tested.
[Xperia Z Original Android Development] alnikki25k:
This is because of the prima wifi drivers. They're unfortunately buggy but I have no alternative. The best solution for now is to disable the wifi optimisation. I'll see if I can find a less buggy version. Also, intellidemand has bugs that won't let the phone turn back on from sleep after a while. For now use smartmax or the tweaked interactive governor. As a testimony to the smartmax governor, here's what I achieved overnight. Went to sleep with 3% battery. Woke up in the morning with this screenshot. :thumbup:

[Xperia Z Original Android Development] kingrion88:
Can I ask why are you removing the CPU boost driver on v16?

v15 somehow is so much smoother especially at multi-tasking. I can feel the speed in opening application and multi-tasking is noticeably faster. v15 is insane.
[Xperia Z Original Android Development] alnikki25k:
That is not because of the CPU Boost driver. In fact CPU Boost does not kick in for some reason. So this shouldn't affect performance :)

What custom stock rom are you using?

Readahead schedule: 1.5

governor: smartmax (most battery-saving governor in this kernel i think), if u wan smoother experience go for intellidemand.

intelplug: on, mpdecision: off.

intelthermal. on.

undervolt -50mv. (u can go more, i'm a bit conservative so i keep it on the safe side).

gpu governor: simple

enable Eco mode, if u r not playing game, disable if you want to play game.

Pls ensure there is no wakelock/battery drain in ur rom (google it if you don't know).

off auto-sync, nfc, mobile data and developer option, I only on when i really needed it.

[Xperia Z Original Android Development] alnikki25k:
Run down your battery to 0. Then charge to 100. Then run it down again to calibrate your battery. This time you must have a better battery. If you don't, I am sorry, it must be the ROM. I am not sure what else could be wrong.
[Xperia Z Original Android Development] mtayabkk:
ok i will try.. am using eXistenZ v4.3.5 | Ultra Edition. and XzKernel-14
[Xperia Z Original Android Development] DrKrFfXx:
Totally unstable. It's been like that since v11 probably. Frustrating blank screens every so often. And since v13, sometimes the earphone fails to make any sound in a call until reboot. Since v14 switching to the front camera in the camera app makes the whole app to freeze, needing to clear cache to make it "forget" it was on the front camera.

It is smooth and everything, nice job on that department, great job I must say, but man it's frustrating and sometimes infuriating to have the phone die when you wanna reply a watsapp or receive a call.

And I'm on the no sweep version, which is supposed to get rid of that issue. And I have tried every governor, every voltage setting, tried default settings, everything, clearing caches, making clean installations and all that.
[Xperia Z Original Android Development] alnikki25k:
You should give me a last_kmsg when anything like that happens. The blank screen issue has been acknowledged and I am looking into it. But the other issues are completely new to me. No one else has had them.

This is my tips on improved battery life:

1) Disable mobile data when not in use

2) Undervolting!

3) Disable MP-Decision crap by Qualcomm and use Faux123 awesome Intelliplug kernel module + ECO-Mode on top of that!

4) Lower screen brightness to lowest when possible!

5) Calibrate battery reading by: Discharge to 0% > Charge full (to 100%) > Discharge to 0% > Charge full again to 100%. Recommended

6) Use ROM with GPU rendering enabled - smoother ROM and less stress on CPU high-freq biasing.

7) Use Interactive and ROW = WIN WIN! My Z sleeps like an baby with that governor / IO combo ;)

8) De-bloat and delete all apps that you're not going to use, trust me.. This helps a lot. Don't forget to wipe cache & Dalvik after this procedure - otherwise you will suffer from nasty wakelocks..

9) Greenify apps like FB..

10) etc etc.. Ask me if you want more guidance / help or send PM!

This kernel has improved my battery life drastically. I was having serious battery drain with the stock kernel. With the 3g on but not using the device in half an hour it went from 88 to 63 and using it I would get like half a day and 44% left. With this kernel I have 77% using it half as much as I normally do (deezer streaming constantly for around 2 1/2 hours and whatsapp and Facebook. Great work Dev! One question.

Damn, I got one wish feature request in your kernel..

Why don't create an kernel built-in module with various pre-set screen gamma / color saturation profiles? Like this:

1) One warm and punchy profile. (= Think the quality of LED-television coloring..)

2) One colder and sterile profile. (=More LCD inspired look, with less punch and more hidden saturation).

3) One childish profile with overvivid and saturated colors. (=Think Samsung GS3 screen colors, on steroids..)

4) One balanced profile with optimized and better looking than the stock look. (=Enhanced and better stock with true blacks & whites..)

5) One profile with the grainy looks of those old televisions (fat ones from 1970 century..) (=Old-school look FTW!)

6) One black & white profile that makes your screen look like old photographies, before color equipped cameras was possible for the masses..

And this should be adjustable / changable with init.d scripts! Would be amazing! :D
