I will do that the next time, it has been more then 12h since I made the screenshot and I used my phone since then.

I get between 1-3 bars most of the time (wifi)

Edit: Didn't had too much time either way since it was early in the morning and had to go to work.

The funny thing is also that the results are very inconsistent, I bet that if I do the same thing again later today (@ night) it won't be this bad. But I'll try to replicate it and see what happens.

Just wanted to let you guys know, that i get around 14,5 h with over 5,5 h screen on time by using these apps or methods:

greenify (allmost all apps greenified. especially maps, facebook (pages),...are huge drainers)

+stamina (whatsapp whitelisted),

+ titanium backup (frozen: chrome, facebook, gmail, throw, mirrorlink, many sony apps,...),

+ tasker (disabling data when connected with wifi),

+ searching for wakelocks with betterbatterystats and freezing/fixing them with titanium backup

+ undervolting (with incredicontrol after flashing doomkernel v4 after bootloader unlock and root; btw: Z also runs cooler like that!)

+ and several email accounts syncing every hour (standard mail app), some facebook PAGES checking, lots of reading with xda premium, about 45 min of watching a flash video (with dolphin browser), lots of reading feedly, greader and google news...and some more quite normal usage I cant remember in detail

Use these apps and methods if you want more battery life and a great smartphone experience. I'm very happy I did all that!

Hope I could help!

Edit:

Forgot to mention: most of the time I let the brightness of the display at 1%. Just a few times I turned on autobrightness for a short period
[Xperia Z Q&A, Help & Troubleshooting] Dsteppa:
I barely use Stamina tbh, but when I go to bed I just enable it because it's supposed to give me better battery life.

With and without Stamina the results are about the same.

Yeah I do, but it's quite clear what is causing this, the WIFI. Last time I checked bbs, my phone stayed awake because of auto sync.

Yes and no.

I installed gm007 wifi mod, but that only adjusts a single file, it's not an ap.
[Xperia Z Q&A, Help & Troubleshooting] gm007:
Can you upload the file that you edit for wifi?maybe there is some difference in the firmwares we are using.

I'll do that later tomorrow, my phone is "sleeping" now don't want to wake it up or the test might be ruined.

Edit: I think it's just my wifi causing all these problems. (Wifi signal being too weak)
[Xperia Z Q&A, Help & Troubleshooting] MafiaManV:
Yeah , undervolting is a nice way of saving ,but i won't unlock BL cause of that :)

1% ?? You mean 10 ?

Here are mine full results after tweaks i posted. Forgot to mention previously... i used 2g all the time . I finally have perfect graph when looking in android battery stats :D

In BBS as its shown i had a total of 6:10h awake time. Screen was on for 5:38h, and Stamina was active for 19mins. So if we remove those 19min out of 6:10h , i end up with only 13min of unwanted awake time. If that is the case after i disable stamina i can finally get battery stuff out of my head and enjoy XZ peacefully :p
[Xperia Z Q&A, Help & Troubleshooting] sfkaudi:
Why you all disable or frees most of Sony apps??????????????

Then you loose the functionality of the phone (stock)! Battery lifetime depend on your usage and some apps

I like the phone as it is SONY and nothing but SONY

There is almost no dif in batterylifetime from my x 10, then xperia s, and now Z in average of use

Ofc the phone is new and use it very much in the beginning.

Just my 10cent

[Xperia Z Q&A, Help & Troubleshooting] MafiaManV:
You have a point ,but even with those apps i deleted you are still left with plenty of Sony stuff.

I just deleted apps i don't need or don't see purpose in my case.

Second reason , nandroid backups are smaller and faster to do, and after clearing dalvin cache i don't have to wait for 390app to get optimized ;).

I always keep backup of some apps in my phone in case i need for example tv out or mirror function ..

and first day of getting to meet "com.sonyericsson.android.wakeup" :laugh: . I hate when i see that in BBS.

My workaround is to keep 2G instead of 3G. Then you will not have problem with that alarm ..

Second solution .. delete fastdormacy.apk in system folder but beware , you may not be able to connect to your carrier :p , so make a backup.

This second solution worked fine on my previous XS , but on XZ i don't have network then :/

This time remove the external sd card and do the test again.

mmc1 wakelock is the highest now, it's related to media scanner or corrupted media files.

You can also turn off the notification in tapatalk to reduce the wakelocks more.
[Xperia Z Q&A, Help & Troubleshooting] Dsteppa:
But I don't even use taptalk! I'll disable completely. The thing also is that my sd card is pretty crucial since I literally have 60gb of music on it. Next test results within 24h.

It's also weird that the results are so inconsistent...

For the next test I'll disable taptalk since I don't use it and use mobile data instead of WIFI.

Removing my card will get me better results, but in every day use I can't live without my sd card.
[Xperia Z Q&A, Help & Troubleshooting] wawyed:
60gb of music? Lol no wonder why the media scanner is draining so much battery, I suppose it's building a library or retrieving info about the music you have. It might stop in a few days maybe when It has successfully classified all your music library.

Which governor is the best regarding battery life on the Z? On demand or interactive? read a more general explanation of all governors but it didn't explicitly tell which is saving more battery life.

Right now I use Doomkernel v5.
[Xperia Z Q&A, Help & Troubleshooting] MafiaManV:
I guess there is not much difference, but interactive should provide less lag, and ondemand scales quicker to low frequency's, so i guess you could save some with ondemand.

[Xperia Z Q&A, Help & Troubleshooting] MafiaManV:
Well, magic 6h were not broken but i came pretty close :) . This run was with stamina switched off. I would say the overnight drop(7%) is a result of bad battery calibration cause the only major alarm was the "android.appwidget_update"

I tryed to locate it by removing some of my widgets but had no luck. Will try to see what happens when i remove them all :). Maybe its not even related to them.. :/. So 2 work days with 6h of screen time.. i dare someone to say XZ has bad battery :D

My latest battery life: 13:20 h with about 6:18 h screen on time. Waited till 0% for the first time (needed to plug it in for 5min after it shut down).

Settings:

This time with doomkernel v5,

Sync on (5 email accounts sync every hour), data on for most of the time, brightness at auto for 3-4 hours and with 1% brightness the rest of the time, greenify freezes many apps in the background, many stock/sony/google apps deinstalled or frozen with titanium pro, nfc off, gps off, stamina on

Governor: ondemand

Voltages:

See screenshots of kernel tuner

Usage:

lots of gReader (rss reader), xda a lot, half an hour youtube/videos, some walkman, quite some time surfing with dolphin, lot 9gag, checking emails, bluetooth on for approx half an hour (file transfers), some whatsapp, often checking time (screen on for short period), 2-3 pictures taken, some wunderlist, a few times checking facebook (pages), making a few short calls, receiving sms,... Cant remember more... but I didn't sacrifice anything :)

Its impressive whats possible with the Z!

Waiting for doomkernel v6 to undervolt even more (700mV).

Also: underclocking isn't working properly for all cores yet...but cpu0. cpu1-3 wont stick and will jump back to 1512 mhz. With mpdecision switched on all will stick but wont go ever offline... So I didnt try it for this run

G'day G1.

I am in the middle of a similar test right now. I'm on holidays so I am at home with a computer available which has given me the opportunity to finally stop fiddling with my phone every five seconds which I have done every day since I got it! I have had the phone for almost a month now and have exhausted the battery from 100 to 0 percent with screen on quite a few times and so far it seems to be a good one, 4 hours + screen time even with bluetooth on for my headphones most times.

I thought I'd take the opportunity to see what this thing can actually do endurance wise.

These are my settings for the test:

Bootloader Unlocked

Latest version of ****lag ROM which has most bloatware removed

Auto screen brightness

NFC enabled

No auto sync apart from checking app updates

Wifi only used when I am on the toilet taking a poop

There is no 4G signal here, but very strong 3G signal (full bars)

I do not have facebook installed

Google chat signed out

Stamina mode enabled

Bluetooth off

GPS on

So far I have received a couple of short business-related calls and sent and received a couple of messages, I also used the GPS for 5 minutes to find a lake near where I am staying and looked up a couple of businesses when away from home. I haven't had any leisure calls because this week, nobody loves me ;p

The phone is kept in my pocket when I leave the house and used as normal mobile phone when required.

When I go to sleep (approx 7 hours per night), I put it in airplane mode as I usually do to prevent brain cancer whilst I sleep with it next to my head!

So far things are looking good: 65 hours uptime with 62% battery remaining.

I only thought to install better battery stats yesterday which I've never used before but for this particular test, I am just looking to see how long it can last if you are going to be unable to charge for a while/ busy living your life and not fidgeting with your phone.

It's like there a lot of tweaking to be able to get the XZ for more than 4 hours of screen time on a charge. Worst is that the battery can't be replaced. No chance of just sliding in a new one. And I'm not too fond of the idea of plugging it on to a power bank or wall outlet half the time of like to use it.
