I have the same problem... htc p4350, wm5 aku3/3.5 the wm device doesn't see the Network Access bluetooth service which the PC is running. (pocket pc doesn't seem to support Bluetooth PAN correctly). This is crap. In the year 2007, simple things like bluetooth pan shouldn't go unimplemented in an operating system built by the richest software company in the world. on a device i paid $500 for. i could implement this stuff myself in less than a week if the code weren't closed source. gosh i hate hate HATE our world.

also the pocketlance website is password protected..

Quick app plug that sped up my tablet considerably. Greenify. Turn off a bunch of memory hogging apps like Facebook, zynga poker, and whatever else in the background you don't use. Took away a bunch of lag and studder. Just a recommendation.
[Asus Transformer TF700] spasch:
I did not get the speed increase as much as the additional battery life back that the apps were eating while the device was sleeping. Good app for me though.

... Personally I find the battery life brutal. It's got to the point that I try not to even use it for fear of not making it even 10 hours with minimum use. I use my Nexus 7 more and more, even for texting with an app called Mighty Text. Even with stamina activated, battery life is short.

With one hour of listening to music at the gym, and a handful of texts, and reading maybe one or two emails, it is basically done in just under 9 hours. With the screen rarely on... My android system shows a higher percent than my screen time because I try to turn it on as little as possible.
[Sony Xperia Z Ultra] ScottishSwan:
I seen you replied to my YouTube video.

Like i said there, you probably have a defective unit or there is something going on. My Z Ultra easily lasts 6+ hours of screen on time and i have no trouble making it through a full day.

Can you share some screenshots of app usage or other info?

There have been a few faulty Z Ultras sold from asia so it would not surprise me if you got one.
[Sony Xperia Z Ultra] ADDICT.ANK:
Do this clear up ur recent apps

And turn off the syncs.

Set ur brightness 40-50 %.

And u'll get more batt. Life.

[Sony Xperia Z Ultra] avsquare:
Same. Mine lasts me a full day with 5+hrs of screen time, most usage is FB, net surfing and messaging using data and some calls and video streaming. Stamina mode not used at all.
[Sony Xperia Z Ultra] ScottishSwan:
Yeah that sounds about right :)

I absolutely believe what the OP said though. I think he is really having bad battery life but, i put that down to the device being faulty or there is a rogue app consuming a lot of power it shouldn't be.

How are you enjoying the beast so far? ;)
[Sony Xperia Z Ultra] avsquare:
It's rather difficult to tell, sure it could be just a rare unlucky defective unit or some other rouge apps but we can't tell for sure until he provides battery usage charts etc.

And yeah, totally enjoying this beast. Previously I was on Note 2, it doesn't have a FHD screen and I moved to S4 which is full HD but the screen size is a little small for videos while relaxing on my bed. Tried tablet options but there isn't really any good FHD tablets with 3G/LTE. I had the Samsung Ative PC Pro but it's a humongous 13.3'' and pretty heavy. I've thought about the Padfone Infinity but again, I rather look at Snapdragon 800 devices. I think Z Ultra came at the right time, with the right hardware and form factor for people like me. It's like owning a Nexus 7 2013 but with full phone functions. Awesome. :good:
[Sony Xperia Z Ultra] Funkym0nkey:
Just do factory reset and give it a go again. Also install gsma battery or better battery stats from play store and see what is eating battery.

I am able to pull about 5 hours Screen on time with more than 15% battery left still.

It might be some app causing wakelock issue.

Turning sync off is not needed and it is pointless. We have a smartphone, turning sync off just makes it that little bit dumb. I am getting decent battery life with 3 email account syncing along with 14 sources hourly updated and synced in pule and twitter syncing every 15 minutes. Also signed into Whatsapp and Hangouts. No issues at all.

Screen I have adjusted to my liking. Not too dark.

If possible post your battery graph from gsam. (Along with the app usage screen).
[Sony Xperia Z Ultra] kkkok8051:
I not sure can be done use this method. But I try my device before and now batt usage came to normal. Just press the power button n the volume up wait until the vibrant 3 time after all your device will suit off and goto charge yr device until full charged (don't. Switch on your device). After full charge prees the power button like normal start . Now try to use your device one day see the result.

Hope can help.
[Sony Xperia Z Ultra] ScottishSwan:
This is how the battery lasted on my Z Ultra after the first charge.

Auto sync was turned on and so was everything else. I was using it very heavy throughout the day.
[Sony Xperia Z Ultra] ADDICT.ANK:
As i think...it's just that it need some time to settle down and calibrate to be set as per ur usage...

the best thing is ur under warranty u can go for replacement anytime u want...(That's the last Scenario..)

And Exactly....What u did is a simple reset so as it triggers to refresh the whole ui...

and do this after doing this let ur phone come to 0% and then plug in charge it to a full 100 % ,let it charge for 5-10 mins extra too,....would calibrate your battery fully....

Then use these.

1. Set brightness around 40-60 % which i guess is more than enough....as it Drains the battery quite heavily..

and try not to use the live wallpapers...

2.Always clear ur background apps...

3. No problem with syncs or data connection....use them as u like that's what they are for. as disabling would result in same or more wakelocks....

4. Check ur battery stats under power mangement and click on graph...The screen on time and the awake time bars should be parallel or closer to it...

Else You can do the things for what it stands for....

Want to ask this, how's the ultra what's ur view for it liked it or not, any best features u noticed.

and post here.. :good:
[Sony Xperia Z Ultra] kramdens:
I'll try some of these sugestions.. yesterday my screen on time was only 1 hour 38 minutes.. I should have taken a screen shot sorry. Today randomly seems to be a little better.
[Sony Xperia Z Ultra] ADDICT.ANK:
Ah no need to be sorry just take a random screen shot.

Just do this to observe charging from 0 to 100% after using the combi power + vol up. Till the 3 vibrations.

Would be helpful.

And post here.

[Sony Xperia Z Ultra] LordManhattan:
A couple of questions:

- Exactly what are you doing with your ZU? Are you playing games? Reading?

- Which apps do you have installed? There are plenty of apps out there that will suck the life out of the battery (Facebook etc.)

- When did you get it? New batteries aren't at max capacity right out of the box. A typical week will normally give you max output (so around 7 cycles)
[Sony Xperia Z Ultra] ADDICT.ANK:
And hows the ultra's response. ?
[Sony Xperia Z Ultra] kramdens:
- I listen to music for one hour during workout

- check email maybe once or twice a day with gmail

- 20 minutes youtube, used to do more with Note 2, but scaled back with this phone

- using google chrome for browser, usually will browse a bit, but keeping that to minimum

- text conversations

- at most one or two calls a day, don't talk much on the phone

- check facebook a couple times, instagram a few times, not much again since getting this phone

- installed apps are: FACEBOOK, INSTAGRAM, TWITTER, MIGHTY TEXT, GOOGLE APS, (MUSIC, PLAY BOOKS ETC), EBAY, NETFLIX, SHAZAM, TD BANK, ZEDGE, and Riptide game which i don't play.

this is day 5 with the phone.
[Sony Xperia Z Ultra] LordManhattan:
Hmm, nothing unusual here. Keep using it until it hits 0% and charge it back to 100% without turning it on.
[Sony Xperia Z Ultra] ADDICT.ANK:
Let them run to get to 0.

But after that always force stop them..and clear the most recent from background.

And most imp.

ENJOY USING UR ULTRA.. :thumbup:

Is it ok to go all the way down to 0?
[Sony Xperia Z Ultra] LordManhattan:
Yes, but don't do it to often.

---------- Post added at 08:15 PM ---------- Previous post was at 08:14 PM ----------

Killing services will only kill the battery faster since Android will automatically start them again. Android is not Windows.
[Sony Xperia Z Ultra] ADDICT.ANK:
yes but only for a purpose its ok to go down to 0...

coz the battery needs calibration so its better to reset the batt. stats and the device is new so it'll take a little time to settle...

no worries just enjoy using it....

And tell us the review atleast...its good to know coz we want to... :highfive:
[Sony Xperia Z Ultra] kramdens:
Forgot to ask, doesn't the combo of power and volume up reset the entire phone??
[Sony Xperia Z Ultra] LordManhattan:
Yup, it's power + vol down (correct me if i'm wrong)
[Sony Xperia Z Ultra] unk_damnation:
Use greenify. This app doesn't only 'kill' apps, it hibernates them. When an app is hibernated by greenify, AFAIK, it can only run when:

1. You start the app itself

2. Other apps requires service(s) provided by the hibernated app and thus it wakes from hibernation

While in hibernation, the apps make zero data footprint (and supposedly no power consumption whatsoever). Just check it out - last time I used it on my (now broken) phone was around two month ago. You'll see that this app doesn't only serve as "battery saver".

I usually combine it with 2xbattery for battery saving, but this kind of thing only works for people like me, who doesn't really need live notification from some apps all the time. But I prefer it over built-in power management from phone's ROM because with these apps I know exactly what is going on and how they work and I can customize it the way I need them to be.

When my XZU arrives, I'll try to compare it with sony's power management.
[Sony Xperia Z Ultra] rockmaster:
Greenify requires root I believe?
[Sony Xperia Z Ultra] unk_damnation:
Damn, I just remembered that. This is what happens when root have become a default requirement :p Have to wait for root then, haha.
[Sony Xperia Z Ultra] joelrwise:
Not sure if this is of relevance, but a couple days ago, my phone felt warm in my pocket while i was at work, i noticed that my battery was plummeting, after about 3 hours of little to no use, it was close to dead. Come to find out, my sd card kicked the bucket and was destroying my battery life. Probably isnt that but figured id say it just in case.
[Sony Xperia Z Ultra] LordManhattan:
Media server wasn't the top process that day in battery usage, was it?

[Sony Xperia Z Ultra] kramdens:
Last night I turned off the phone with power plus volume up and mentioned and waited for 3 vibrations. Plugged in to charge. This morning I woke up and turned it on. Was I supposed to notice anything. Just turned on, nothing reset or anything. Just wanted to make sure that was right.
[Sony Xperia Z Ultra] ADDICT.ANK:
It's just a soft reset...so there will be no changes to note...it will just refresh the

There's something definitely wrong there? Could you tell us what apps you downloaded from play store.
[Sony Xperia Z Ultra] jack4uno:
Try claiming your warranty. I think you might have an issue with your battery and/or phone.

My screen time easily lasts for over 4 hours on a full charge with data/gps/wifi all active.
[Sony Xperia Z Ultra] LordManhattan:
That's not normal at all. Something is killing your battery in the background. Install BBS from here, open the app, close it again and turn the screen off. Let it stay in standby for an hour or so and open the app again. Check the Kernel Wakelocks and Partial Wakelocks. Also, install CPU Spy from the Play Store (Free) and see if it goes into deep sleep when you turn the screen off.

Edit: Do you have a SD card in your ZU? If yes, which class is it?

My stats after running wake lock app for 3 hours
[Sony Xperia Z Ultra] ADDICT.ANK:
First stop the sms backup app

phone's is going in deep sleep but also have been awake more than expected..

Is android os and system are still around 15-20%.....

what's the brightness set to..keep it on 40-60..

Stamina mode is good but it does make ur OS and system go high....stop the calendar storage from battery tab if its there....your android wakeup service is keeping ur phone awake..which it should not beyond a limit...

click on it in the wakelock detector and open it u'll see the settings menu and stop it..

do this first

And last and important thing...you have to start using like your other device...

so that it can settle according to your usage...use it like ur nexus pls..

Dont worry u have warranty so no need to worry at all...just give it a try....

and try to stop the extra apps as they eat out a lot of battery....basically its the screen which uses the most but setting the brightness would lower it..
[Sony Xperia Z Ultra] kramdens:
whe n you say stop my android wake up service are you referring to Sonyericsson.android.wakeup? I force stopped it as you said. when I went back to it a half hour later I still notice that the count went from 3 1380 to 1440, so even with it force stopped it still wOkeup another 60 times

This app will help you track rogue apps well:

https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en

Install it and activate it and then let it watch a full battery drain cycle.

Before the battery dies, load it up and check what's been using up all your battery.

I would also disable Google+, Facebook, and Instagram syncing / location / notification services. All of these will hog data. Opt for emails instead if you'd like real time updates as those are much more battery efficient.

Talk about an oxymoron
[Sony Xperia Z Ultra] gunblazer:
Hey OP, regarding your battery issues. I've found from experimentation that under some unknown conditions, stamina mode actually drains a ton of battery in the form of radio/connectivity wakelocks that drains even when your phone is off and trying to sleep. There is something definitely wrong with the ZU's implementation of stamina mode. This does not seem to be affecting everybody though.

Try going one or two days with stamina mode fully off and let me know what you experience. Simply having stamina mode off solved all my battery problems. (Also, it's not even needed as this phone doesnt drain much in standby to warrant stamina mode)
[Sony Xperia Z Ultra] ADDICT.ANK:
Exactly stamina mode will make your android system and OS both go high and will drain ur battery more, in order to save the resources to run itself..

Just turn down your screen brightness only and see that will improve your battery hours...

[Sony Xperia Z Ultra] ADDICT.ANK:
Well update was supposed to fix some bugging issues like battery and other stuff...

So its good that it somehow fixed it...and would bring more stability to the battery as per ur daily usage..so i would say again use it without worries simply..

And also see the stats with stamina mode on and off..How much hours you get in both ways.

And your device is not faulty..ok

Good luck and post the results..

Personally, I GIVE UP. Battery life is HORRENDOUS ... worst battery on any phone I've even had.. since update, drains 5% within less than 30 minutes, and that's WITHOUT TOUCHING THE damn phone... NOTE 3 might be replacing this FAST, but I'll really miss the screen size! :mad:
[Sony Xperia Z Ultra] ADDICT.ANK:
After 100% it discharges a bit fast till reaching 90..its for the batt.

And also charge it from 0 to 100% again. Dont use auto brightness. Keep it as u mentioned from 40 to 60%.as being constant helps.

I dont want to say this.but sony

Did put a little less powerful batt. In a beast like ultra z.so its hard to get a lot out of it. But it doesnt mean this that it wont give u the specific battery time which it should.

As u updated it'll take some time again to settle. And imp stop the com.sonyerricson.wakelock from settings like earlier..would help surely.

And I would say u turn off the stamina mode and use a 3rd party batt. Saving app instead like du battery saver etc. And see does that make any difference..

And post it here pls.
