So....let's talk more about bugged Deep Sleep on Stock 4.3 ROM!

i currently to not have inculded Mobile Data so thats Deactivated.

2x Email Push Sync, and all other sync.

Thats what happened with 53 Minutes Screen on time!

Assuming it was Email, i switched from Push to 1 every hour.

another interesting fact i've seen here:

The Wakeups are clearly caused by WiFi! But the Battery life does NOT get better if WiFI is deactivated ~.~

But well, there clearly seems to be something wrong! (BTW; here i deleted my Google Account because last Firmware there was a bug with new added credit card! so NO google services Sync here in this image! Email was set to every 1h)

ah well, here is a normal "Daily Usage"

4h Screen on? Not that bad you wanna say? YES! IF there would NOT be 22% Screen and 40% Android OS -.-

really interesting is this picture here! i deactivated WiFi, then it took around 2h to cool down(?) and it worked how it should! No more Battery drain or whatever.

Wakelocks are as always the same, "suspend_backoff" and "mmc1_detect"

For now i have played around enough with Stock rom. I'm backto Beanstalk. bb

If even the Stamania modus knows something is wrong....
[Xperia Z General] beni8978:
Don't have android OS consumption.Make a clean install.
[Xperia Z General] Haldi4803:
i'm back on Beanstalk and kinda happy with that.
[Xperia Z General] beni8978:
Best battery life till now on 4.3

Apps greenified and some app permissions disabled.

5% remained so guess 5h 35 screen on time.

Thats normal??

Thats normal??..I,m on 4.3 stock odex rom with root, without sync.....only a rutine wth tasker every 2 hours on gmail.....android so drein de battery!!!! :crying:
[Xperia Z General] Haldi4803:
i'd recoment flashing via SEUS. if you can live without root for a while.
[Xperia Z General] testnumero:
nice !

how is it possible that your "Android OS" is so low ?

i have greenified all my apps but "Android OS" still kill my battery :( it's always higher than SOT :(
[Xperia Z General] beni8978:
Do a clean install(factory reset)

Did you ever try the kernel from existenz rom for undervolting and battery life?Is it better or about the same (except overclocking) compared to hodor?Thanks.
[Xperia Z General] TechKiel:
You cannot use the kernel that is included with eXistenZ because it is the Stock .292 Kernel.

Using the Stock .292 kernel with eXistenZ, I usually get around 2h 30mins (worst) - 3h (best).

Using Hodor Kernel with undervolt, I get around 3h (worst) - 3h 30mins (best) but for once, I managed to get 4h.

I use LTE a lot to maximize my data plan. I have Stamina Mode and Greenify+ enabled at all times though.
[Xperia Z General] xdagfg:
Aright thanks.Il do some underclock with the 3.5 (to get decent time)and if not ...guess i have to unlock bootlaoder and flash hodor for undervolt.
[Xperia Z General] TechKiel:
If you plan to unlock your bootloader, make sure to backup your TA partition using BackupTA: http://xdaforums.com/showthread.php?t=2292598

Have fun experimenting!

My usual settings:

[Xperia Z General] xdagfg:
Yeah ill take care of it .Thanks also for your settings.
[Xperia Z General] afeeq:
how is your SOT with this setting??
[Xperia Z General] 115dan:
These settings are not good, i get freezes and reboots. This is -200mv under stock values. The best for me is -150mv, stable and good. I get 5h 30min-6h of screen time with this configuration, without i get 5h.
[Xperia Z General] TechKiel:
These are the default voltages from stock. I don't see how did my settings become "-200mV under the stock values."

My current setings

These settings are good for me because my CPU binning is: PVS: 4 (faster)

Not all Qualcomm CPUs are made equal even if they are of the same model.

In our case, APQ8064 has 4 binnings.

PVS: 1 (slow)

PVS: 2 (nominal)

PVS: 3 (fast)

PVS: 4 (faster)

The higher you cpu binning is, the less amount of voltage it needs to run.

See this thread for reference: http://xdaforums.com/nexus-4/general/poll-cpu-binning-t2052496

Use the instructions in that thread to determine your CPU binning. Undervolting your device beyond your device's binning will result to reboots due to the insufficient voltage that is being fed to the CPU.

Good luck experimenting!

Hi I have a locked bootloader, using existenz ultimate 3.5 rom is there an app or setting or build prop edit I can do to undervolt? Every app I've tried says this kernel can't undervolt.

[Xperia Z General] jedisurfer:
I'm having the same issue I get about 2% drain per hour on standby, msm hsic host appears to be awake 1/3 of the time and prevents it from going to deep sleep. This is on the tmobile c6606 and has wifi calling (not sure if this causes it to stay awake).
[Xperia Z General] xdagfg:
2% is to much.I get around 1% or bit less on standby.
[Xperia Z General] TechKiel:
Have you tried turning off Google Backup?
[Xperia Z General] jedisurfer:
wifi has some really bad hsic_msm_host wake lock when wifi is turned on that will keep the phone awake. Is there is any rom or update that will fix this?

The on screen time is also terrible. Even with brightness scaled down and max cpu set at 810mhz, gpu at 200mhz it drains something like 1% for 2 min of screen on time. I don't game so this is just browsing the internet.
[Xperia Z General] xdagfg:
what rom you are using, kernel and settings?
[Xperia Z General] jedisurfer:
I've have all google backup disabled, no chrome, no google now. I have tried all roms and default kernels on the roms, existenz 1-3.5, tmobile default 4.1.2 and 4.2.2

post a picture of your battery life along with screen shot of wakelock detector how much time it uses( hsic_msm_host) on lets say few hours?il compare with mine and see .
[Xperia Z General] TechKiel:
You cannot undervolt because your bootloader is locked. You are currently using the Stock .292 Kernel which does not permit undervolting.

You can only tinker with these settings if you have an unlocked bootloader and a custom kernel.
[Xperia Z General] leonmorlando:
I'm currently on a stock Sony ROM (.157) with UBL and Doomkernel port for stock devices. I can't undervolt to even -25 without the phone freezing and rebooting, should I be using hotplug and not mpdecision? or is there something else that's causing the problem?

My Xperia Z battery is awesome,after removing play store and google play service and other bloatware.Then Used "advanced battery calibrator " and "repair battery life " app to callibrate battery.

Got 6 hour+ on screen time(3hour internet browsing with 3g data , 3hour+ watching 720p movie with mx player).Have not got 4.30hour before.Without Undervolt, on locked bootloader and stock 283 indian firmware.
[Xperia Z General] langeveld024:
Nice! But the battery calibration thing is placebo: all it does is deleting "batterystats.bin" from the system in order to "reset the battery".

But since jellybean, android deletes that file at 100% charge itself so it is not needed to calibrate anymore.

Removing the play store will make a big difference.

Good to hear ur enjoying and thanks for sharing bro
[Xperia Z General] xdagfg:
whats the negative thing when removing play store?(besides not being able to download stuff from it) ?.
[Xperia Z General] Akinaro:
especially what if you have loots of paid app and you want to get latest versions without playing with copy-paste from other sites. Maybe its nice for people who get cracked apps, but what about others?

Its possible to remove all that power hungry google bloadware, but still get only GooglePlay for app updates?

to be on topic:

On stock 4.4 rooted(no other moding) with Greenefiy I get for most of time about 12h of work(3g network, but no internet transfer, wifi all the time, minimum brightness)

For most of day im watching about 30-60min of youtube, 1h of games, about 1h of internet over wifi, about 10pics per day, and 2-3 music.

I never expected too much from battery in XZ, so I was prepared for it when I got it. but still this 2-3h more would be nice :]

Every processor is a little different so first test the values on your phone before you check the set on boot because it might just not work for you even if it's stable for others. For example, my phone reboots with the values scoopdreams posted that were stable for him. Or your device might go even lower, but you gotta test it by yourself.

This is my first phone with this type of resolution and FHD screen, bear with me.

In the previous phones (Galaxy S3, Note II, iPhone 5), I haven't experienced a battery drain of 10% while it is in standby mode. I was hoping that maybe the battery just needed to settle in, but the past few days where I've charged it to 100%, went to sleep and woke up, I found it at 90%.

Is this normal? Has anyone else been experiencing this? Stamina mode is on, so Wifi, data, etc. is all turned off.
[Xperia Z General] JPWOA:
Something must be running in backgroud!

With all connections off and Stamina Mode on you should experience 0-1% during 7-8h.
[Xperia Z General] Mr.Dadulka:
I had the same... there was wakelock in bbs related to fastdormancy - I deleted/disabled this file in root/system/apk.

Also disable location servise in settings/accounts/google (not that with gps).

And freeze Chrome! There is some bug causing drain too.

- I have also frozen G Maps as it sometimes might drain the battery too but I will try to unfreeze it and will see (cell and wifi determination of location still works).

[Xperia Z General] brutal_noise:
wow really , that seems impossible to me ... anyway great result mate !
[Xperia Z General] grievous2004:
These are my suggestions to get a great battery life:

- if your carrier does not support fast dormancy: rename/delete fast-dormancy.apk in /system/app (as someone else suggested). You don't know if it's supported? Check wakelocks with BBS: you'll have no doubt if you see a consistent related wakelock

- if you do not use google talk: open it, log out (and uninstall/freeze if you don't care of it)

- in google account settings -> ads, disable google ads/adMob; do the same in play store settings. This because google uses your position to give you aimed ads. (you can even disable google position in settings but you'll have to enable it when you use maps, ecc..)

- check maps and latitude settings: make sure it does not monitor constantly your position.. it's a huge waste of battery imho.

- undervolt, man! It always helps :victory:

- use Greenify app: it hibernates the apps you select when the screen is off. It's very useful if you have nasty apps always running in the background. e.g you can hibernate maps and avoid the consequent (and annoying) wakelocks. It only works on user apps (so if you want to hibernate a system app, you have to convert it to user app (with TiBu) or uninstall it and install again from play store).

- pay much attention to STAMINA MODE: it may not be working properly and cause excessive battery drain! You can easily check if it's gone crazy looking at the expected standby time in the settings menu: if it's the same with stamina on and off.. well it's not okay. You can do the following: disable it and live without it or "reset" it: you have to go to settings->Apps->All and find something like Eco Controller Service; kill it, delete data and reboot. It should be working now but consider that the issue will likely be back.

- use an app to toggle the wifi status based on the availability of a known network: it's useless having wifi turned on and scanning continuously while you're on mobile data. I recommend Smart wifi toggler or Auto wifi toggle.
[Xperia Z General] JPWOA:
Thanks for the great post!

One question...Do you have to add Greenify to the Stamina exceptions or it will work normally?
[Xperia Z General] grievous2004:
Nope! They have different purposes.

Stamina, afaik, blocks network access to all the apps (except the ones you select) when your screen is off (after a certain amount of time).

Greenify hibernates completely the apps you select (like the iphone multitasking): when you need one of these apps, you open and find it right where you left it. So Greenify does not need any network access and is not interested by stamina mode.

However, please read carefully the first posts of oasisfeng to understand fully the functionality of this app.

And I found one more giant wakelock: pay attention to the Throw feature! After using it and selecting back the phone as playback device, the app Devices keeps running not allowing your phone to sleep properly. I usually kill it when I'm done with streaming to my tv but perhaps I'm doing something wrong as I haven't read of anyone with this issue.
[Xperia Z General] JPWOA:
Actually you're wrong! The Stamina mode don't block connections only, it also "shuts down" or "hibernate processes"...or at least it should be that way!

I tested myself and I can confirm that Greenify will not work with Stamina mode if it's not white listed!

I have facebook on Greenify! Without Greenify being white listed facebook shows a status of "Pending".

If I have Greenify white listed on Stamina facebook goes to "Hibernated".
[Xperia Z General] sipe1:
Is better to use Stamina mode or Greenify?
[Xperia Z General] grievous2004:
mmhh don't really know at the moment. I'll test it tonight and report back. However I don't think stamina hibernates processes.. it disables data access and turns of lots of features but not apps as I still can get wonderful wakelocks :laugh:

Anyway I'm experiencing difficulties in hibernating fb both with stamina on and off at the moment.. let's see.. anyway it's one of the crappiest apps ever!

Ok, you are absolutely right! It has to be in the whitelist. I think they can coexist well as greenify can keep apps hibernated even when the screen is on. I will keep them both activated and see what happens

You can hibernate fb with greenify but uninstall it first and put it back from play store so it won't show up as a system app anymore
[Xperia Z General] JPWOA:
Use both ;)

:)

Yes, the two working together seems to be the best combination

DoomLord released v3 kernel which support .434 firmware. Going to try undervolt :)

Doomkernel v3 <3 GPU underclocking!

Thread hasn't been active, I tried using the undervolt settings in the OP but it made my phone reboot on some apps, what are the best settings not to interfere with everyday use?
[Xperia Z General] xHok:
You just have to try it. I used a voltage someone posted here and then I was raising the top couple frequencies till it stopped rebooting (not the best way to do it :D ). Every phone can have a little difference in the stable voltage but do NOT save it for reboot until you will be sure it is stable.

Hi,

Why should we underclock the GPU?

For life expectancy or less heat? Since we can't undervolt it yet we won't save any battery, right?

If underclocking helps battery, what's the default mhz(or mhz-range?) of the GPU (incredicontrol can't read it, android tuner free says something between 325-400)?

How much lower is appropriate/a quite safe bet? -50 Mhz?

Do you test the GPUs stability with 3dmark and/or antutu?

Ps: already undervolted cpu, works great!

Hi Guys,

can someone tell me and link me the best app to stress and test my XZ for to ceck if my undervolt is stable?

Thanks
