Everything you don't want or need, i.e most stuff from Sony. You should root it and do that, and if your battery is still horrible after a couple of days, then un-root and do what ever you want (trade it back, sell it etc.)

Note: This is something that most flashaholics around here knows, and that is that every time you update/change ROM, the battery won't be at full capacity and it'll drain like a mofo for about two-three cycles. It's the same thing with official updates from OEM's. You should keep using it as normal, let the update settle and see how things are in a couple of days.
[Sony Xperia Z Ultra] ADDICT.ANK:
Exactly ..update needs to settle a bit and will take two to three cycles...so pls wait..

and charge from 0 to 100 for refreshing the battery stats.......let the battery drain completely till it gets off and then do it

use it...i know its annoying but this would let u gain knowledge and will be helpful for you later on...and would fix the damn issues..

Just post for help.......gimme a :highfive:

Is this battery so terrible for everyone? This thread has really put me off this phone. I'm thinking of cancelling my order. Does anyone who had a note 2 know how this phone's battery compares?
[Sony Xperia Z Ultra] LordManhattan:
Nope, i've seen screenshots from people with 5-6 hours of screen time.
[Sony Xperia Z Ultra] ScottishSwan:
Battery life for me has also been great. Minimum of 6 hours screen on time per charge and I can easily get through a full day.

Compared to my Note 2, battery life is no better or worse. Both equally as good. Note 2 just has a replaceable battery.
[Sony Xperia Z Ultra] Mhotep06:
Battery has gotten better for me. Bought one from eBay seller who only had for a few days and didn't like it. First day I used it only made it 4 hrs with casual use then battery died. Since then everyday it last longer. Today I've been using it for 13 hrs with constant alerts phone calls, surfing etc and I'm at 5%. So don't let this thread stop you. Seems like battery has wear in period.
[Sony Xperia Z Ultra] sman55:
Thanks for your replies about battery life. It's reassuring to hear your experiences.
[Sony Xperia Z Ultra] ADDICT.ANK:
Exactly battery life will get better as per usage or should i say day by day.

But it will

How much time u got now

[Sony Xperia Z Ultra] khushrooirani2000:
ive been using XZU for over 2 weeks..1st 3-4 days the battery wasnt good, but it takes a couple of charging cycles to get set..since then if i keep stamina mode OFF it gets comfortably through the day and with stamina mode ON it gets through well into the 2nd day

ofcourse ive taken precautions of not installing lots of apps i dont need keeping my brightness to 40%.

hence its completely inaccurate to classify the battery life is "TERRIBLE"

and i had a note 2 before this..i didnt see much difference in terms of battery life.

and my firmware .471, not updated yet but i hear 475 is even better on battery life.
[Sony Xperia Z Ultra] kramdens:
I'll just give you an update since I started this thread, I do have the Note 2. With the Note 2 I had every service ON, from wifi, Bluetooth to GPS and had a fairly high brightness on at all times. And at no point did I ever worry about, or even look at my battery.

With the UltraZ it's been all over the place. I had awful battery life, but following all the great suggestions on the forum it got better. Also giving it time to settle it got better. Also after the first upgrade from 461 to .471, I did a factory reset and that help as well.

Than I did the second upgrade to .475, and it started all my problems all over again. It was abysmal. I would love to know what people have turned on that say they get 6 hours of on screen, because that seems impossible to me lol!!

It's a smartphone, and I don't want to compromise. I want to use it as a smartphone, so I keep everything turned on.. and that's what I like personally. So I know it will always take its toll on battery.

Anyways, after the upgrade to .475, it got bad again. So yesterday, like the first upgrade, I decided to reset the phone to factory on a full charge.. and AGAIN that seemed to really help. Yesterday I had pretty decent battery. At least for this phone. So I guess, after every upgrade, for me at least, it seems I might have to do a factory reset.

Stamina mode is one of those questionable things, but it seems to help more on my specific phone. Although, randomly it stops working every day, so I have to go into settings, apps, extended standby mode extender and clear cache, and then the stamina works again.

I love the phone, but it looks like I will have to do factory resets after every upgrade to get decent, but not great, battery life.
[Sony Xperia Z Ultra] sman55:
Thanks for that info. I have a couple of weeks to decide so i'll see what people say about battery life after a few weeks of use. I'm quite a light user during the week but do a lot of walking at weekends using gps aided mapping programs such as locus pro and gps4cam and the note 2 was great for that in terms of battery life. Thanks for the tips about resetting after updates.
[Sony Xperia Z Ultra] ADDICT.ANK:
With all the things you said...

when we update we need to reset it...that's why there's always a prompt on updates that backup ur data...So it's supposed to be reset after every update...

As it clear the caches and gives the phone a fresh start...with all the new stats and to adapt according to the usage data recorded in stats...

and it does take time..

well anyways how's the batterylife any improvement or not..

And also confront the issue with sony or from where u bought it.....

As the phone is new and have the warranty..

and let us know what they say about it first..
[Sony Xperia Z Ultra] hamdogg:
I was just about to suggest better battery stats to see what the CPU wakelocks were draining your battery so quickly... But see that it has been suggested.

how is everytone finding the Ultra?

I had the note, got the S4, and now looking at the Z ultra and thought freck! Looks fantastic!

What are your impressions guys? How are you finding the device?

Thanks... trying to figure out if i should make the purchase.. I'm very split about this purchase....
[Sony Xperia Z Ultra] mcteague:
This device is awesome, battery life is not a huge problem when screen on time is about 5 hrs, it's all down to how you use it.
[Sony Xperia Z Ultra] hamdogg:
Thanks for the reply...

Upon researching I've found that there are three variants of the Z Ultra... HSPA+, LTE and duel band LTE... They also vary in price quite a lot, with HSPA+ being the cheapest.,. Mobile data speeds are not a major for me, so I think i'll just go for the C6802 as well.

(if I do purchase this beast!)
[Sony Xperia Z Ultra] mcteague:
Just walked 3.3miles into work which took 54 minutes with gps on and phone in stamina mode and I lost 2%. Not bad.
[Sony Xperia Z Ultra] hamdogg:
Many hard resets? device frozen much?
[Sony Xperia Z Ultra] mcteague:
Once but I think it was Go Launchers fault not phone. There's no X-reality at the moment but should come in new update soon, in fact next software update has already been certified.
[Sony Xperia Z Ultra] xene68:
My battery life is good. I'm not experiencing the problems reported here. It's currently at 85% after 6 hours from full charge and u have been using it.
[Sony Xperia Z Ultra] kramdens:
How do you use it? I have gps on, wifi on, bluetooth on, locations on, google plus, twitter, facebook all syncing with push notifications... I basically use it as a smartphone, I don't compromise my enjoyment at all. With other phones, I have had much better battery with ALL those on.. with this phone, not so much.

After 6 hours I would be closer to 50% so how do you use your phone?? Can you be more specific?
[Sony Xperia Z Ultra] clubtech:
Me too. I just use it a smartphone like i use all my devices and this device just drains battery very fast with moderate usage. After 8 hours of moderate use (not a lot of screen time at all, maybe 1 hour) i'm at 20-30%. When the screen is off i noticed it drains 6-7% per hour just sitting there.

There are no wake locks that look suspicious, the CPU enters deep sleep properly.

I think, but not verified yet, that they have a bug with Bluetooth on this phone. I will try and confirm this later today.

When a BT device is connected such a headset and you receive or make a call, when the call end, the device doesn't close the active BT connection. it looks like it does, but the actual active connection to the BT headset remain open and i think it drains the battery.

Today i turned off my BT completely and we will see how the phone drains battery.
[Sony Xperia Z Ultra] ADDICT.ANK:
And how are u using it now?

Seen any improvments yet ?

I would say u shud continue to use it as a ultra i.e. Smartphone..

And also talk to ur sony service centre abt ur battery issues..

And try a battery saver app and see if it makes any difference. Just to see the stats
[Sony Xperia Z Ultra] kramdens:
I am using it as usual. All services on. No improvement really to battery. Although some days it is much better than other days with the same use, not sure why that is. But overall it is not all that great. I can't imagine any phone losing only 15% battery after 6 hours of constant use, like the previous poster said.
[Sony Xperia Z Ultra] kramdens:
Hmm.. interesting. Sounds similar battery wise. Good to know that it's not at least just me! Let me know your findings.

thanks!
[Sony Xperia Z Ultra] xene68:
I use it very much like you do but don't have gps on. Facebook, Twitter, 3 email accounts syncing every hour, one on push. Now battery is at 43% and 2hr 30 on screen time. Done some gaming too like order of chaos and star legends. It's lasting like my old galaxy note 2 did. Display is about half full on brightness, not auto. Latest firmware installed too.
[Sony Xperia Z Ultra] ADDICT.ANK:
Great then.keep it like that. And the issue is due to the specs as the specs are high and so as the os but the battery capacity is a bit low to fulfill the requirements..

But still always reboot ur ph. Once in a day or two..
[Sony Xperia Z Ultra] gordonyz:
Hi OP.

I was having same issue like you. I got very little deep sleep time out of my Z Ultra before.

Today I decided to log out my Skype account -- which is my biggest partial wakelock. Now I'm able to get decent deep sleep and battery life is up significantly.:victory:

Now I'm deciding to keep or uninstall Skype or not.

Edit: I have terrible experience with Skype on C6802. It rings up so late, I never got actual notification from the app though all notification options are checked, and front facing camera never worked on video chat. Most of all, it consumes 1/2 of my battery life.
[Sony Xperia Z Ultra] LordManhattan:
Yeah, welcome to Skype. It's the same story on my Note, other Android devices i've used, and the iPhones i had before those. If i need Skype, i'll install it when i need it and uninstall it right after i'm done with it. It's clearly a product of Satan.
[Sony Xperia Z Ultra] erik0072:
Hey All,

I have ordered the Z ultra too and I've read in this thread that it helps battery life if you reset it and drain battery untill 0% and then charge it to 100%.

Is this a good idea to start with when my ultra z arrives too improve battery life?

And what is the right order just to make sure;

1 drain the device to 0%

2 plug in the cord and give it a reset

3 charge it to a fully 100%

Thanks in advance for the answers.
[Sony Xperia Z Ultra] ADDICT.ANK:
Yes it does help

As it gives the stats to phone for accurate battery usage and life.

Battery has been DRAMATICALLY better since the upgrade to .510
[Sony Xperia Z Ultra] golfinggino:
glad to hear this - now i just need to receive the update - will give it a few more days and if not i will root it and get the update manually - thanks for the info

Battery look fine. First day of manually flashing 510 then updated on Pc companion, wifi and screen on with over 100 apps downloaded from play store heavy benchs, and passing my time to setup all it feel good for a first use from 100% to 10% 4h15 never went to sleep. Hahahaha

Need a favour can u post the camera.apk and the files of cam. For ur device pls
[Sony Xperia Z Ultra] OnkelAlbert:
Have my (German LTE version) ZU since yesterday and without any statistical data (not even fully loaded yet) based on the first usage starting at the 55% battery out of the box it looks great. To big drain during the night. Right now I started a full screen streaming video at 2% to get the battery to zero and it played for more than half an hour - so the % calculation seems to be quite strange.

Full load now, let's see. But after I almost cancelled my purchase after reading the forum it seems to be better than expected. Device came with .510, no updates available.
[Sony Xperia Z Ultra] LordManhattan:
The battery is new and hasn't been "calibrated" yet, so keep using it for about a week, and the battery status/indicator should in theory get a little more accurate.
[Sony Xperia Z Ultra] bASKOU:
Yes the last 14% last really long and the beginning decrease really fast, it scared me at first. But in the end battery life is really good. Most devices have a calibration problem, most I had took long to use from 100 to 90% kinda normal from 90 to 15% then decrease drastically from 15 to 0%
[Sony Xperia Z Ultra] xtraviolent:
I managed to nail down getting the phone to enter deep sleep without being interrupted.

Went to sleep last night at 99% unplugged and when I almost 8 hours later, it stayed at 99%. (0.1% / hour)

I'm also a fairly heavy user browsing throughout the day and I get over 6 hours of screen on time consistently.

- Non-LTE version

- Wifi GPS on

- Apex Launcher

- I don't use any SNS so I've disabled every SNS related process (Twitter, Facebook mainly) and also disabled Chrome since I heard that they drain battery quite a lot (I use Boat browser).

- Disabled Sony bloatwares such as the Sony Lounge, Sony Select etc but rest were untouched.

For the first 4 days of using the phone I charged overnight to 100% till right down at least 5% before going to sleep and I think that helped calibrating the battery life as I've noticed my screen on time increased by around 30 minutes each day. I only used to get 4 hours of screen on time at first now I get 6.
[LG Optimus G Pro] fryguy128:
Tonight after my phone went dead, CyanogenMod would not boot at all for me. Luckily I had a nandroid of the version I was running and was able to fix the problem without losing any recent data.

The prerequisites for this tutorial are a recent nandroid made in TWRP and TWRP on your phone.

Warning: Before continuing be aware I am not liable for any loss or damage occuring from following my tutorial.

Now that that's out of the way,

1. Boot into TWRP, I don't believe CWM will work but, I can't confirm. If you can't get into android to reboot recovery, you'll want to hold down home+lock/power+volume up.

2. If you have booted into recovery, the hard part is out of the way. The next thing you'll want to do is enter the restore menu and select your latest back-up.

3. This is the important part if you do not want to lose any data. Make sure that ONLY System is selected. If you don't do this and continue, there's nothing I can do to recover your data so don't ask.

Comment and thank if this helped you.

Backup/restore on TWRP

I do not have the update by Verizon, but I have the new kernel and Twrp. I have read about questions with Backup and restore with Twrp. I have two backups, one with only the three items checked: boot, system and data and the other with all five checked. I have not run a Restore yet because I have read about issues leading the owners to go back to stock and then root again and regain all their data back. Am I correct in reading that If I do a Restore that I should uncheck Boot, Data and Cache and just leave System checked. Why... anyone else have this issue?

I really don't want to soft brick my phone...

Thanks

PS I am not running Cyanogen Mod and would that make a difference??
[LG Optimus G Pro] fryguy128:
You could try just restoring system first and if that doesn't work restoring all of them. If your phone is running ok right now there wouldn't be a reason to do this though.

LG Optimus G Pro (LG-E980)

HP Touchpad (Tenderloin)

[Xperia Z Q&A, Help & Troubleshooting] flintston314:
Hi, I noticed that my Xperia makes an awful lot of pictures with red eyes.

Now I wanted to correct those via the built in photo editor. I know for sure that ICS (4.1) had red eye correction built into the default photo editor, but I can't find that in jelly bean (4.2).

Did Google really get rid of that feature?

If so, is their a way to add it again? Every other editor I tried tends to overwrite my geotags so using the default editor would be better.
[Xperia Z Q&A, Help & Troubleshooting] flintston314:
Could anyone please at least confirm if they still have the redeye correction feature in the crop menu if the default photo editor (within gallery) that comes with stock 4.2.2 423 or later?

[HTC Droid DNA] swiftinmotion:
I'm on my second DNA I moonshined both phones and a week ago I flash the cm10.1 and had no data ie. Couldn't make a call couldn't text. Internet and everything worked after flashing cm10.1 it stuck on the first screen the "activating" screen so I flashed my backup which is the ROM it comes with out the box. And had no data there also.. Android 4.1.1. Sense 4.1+. Verizon exchanged my phone lucky for me. So i moonshined again and s-off and rooted. But scared to flash again in case this happens again. Coming from gs2, galaxy nexus and gs3 I haven't had to mess with bootloader at all. I guess where I'm going is what do I do if this happens again. I see a option to reset from boot loader? Will that fix the issue if it happens again. Is there something I'm missing before flashing?? I want to flash newtoroots sense 5 ROM just scared. If someone can provide some info on where o went wrong gladly appreciate it.
[HTC Droid DNA] d08speed3:
If this happens you can try the reset from bootloader but of that doesnt work you'll have to do revones return to stock method. There's a thread. Pretty much flashes the RUU (stock everything) and flash stock bootloader. Its not hard. I did this the other day to put my phone back to stock for my replacement.
[HTC Droid DNA] finanandroid:
Sometimes That happen when a Rom like a JB 4.2.2 required to wipe the System in addition to the normal wipe/factory reset. so if you tried

to activate the phone which you already have activated (most skipp activation) the SIM Card reset (someone else said fry) and your location and phone number get lost. so RUU fix all the troubles, but now you can safe flash NOS 4.1.2 very stable normal wipe. is good idea keep in your computer a Stock Restore Backup file. Reset from Custom Recovery won't fix the issue, has to be from Stock Recovery.

[HTC Droid DNA] xlxcrossing:
Based on the info you gave none of your issues should be caused by the boot loader or moonshine, sounds like a ROM side or kernel side issue. The radio mode may have been switched when you flashed Roms. It should be on CDMA/LTE when on Verizon and WCDMA/GSM when on gsm/Sim. Not sure how APN settings are managed within CM non gsm im not sure there is even an option to edit them. These settings (radio/apns) deal with how the phone connects to the network. Voice and text should provision automatically on stock android, not sure how to manually provision. On Sense based Roms as long as a compatible version of EPST is running one can use special dialer codes to manually provision the phone for connectivity as well as access other helpful settings. From sense *#*#4636#*#* would be the code to reach the Phone Information containing the radio mode switch I mentioned previously.
[HTC Droid DNA] swiftinmotion:
Thanks for the replies guys. Yeah on jb4.2.2 that activating screen is usually passed right by for a quick second bit some how my phone got stuck on that screen. Oh well its rattled me to the point of not flashing lol. Just rocking nova launcher with some icon packs. Might try sense 5 ROM tonight. Wish me luck! Lmao

Some Info

RUU (after Stock Phone Reset) is the only way to Recovery from this, this happen to me once, what happen

-Operator Network Change (u can only have Internet)

-APN Setting Doesn't matter if you change it a least it be edited . Unknown Network and Mobile/network type unknown

-Phone Info state Phone number 0000000000 Zeros, Min Unknown, PRL 00000, Meid zeros,

-Restore from you back up out the box: does not work or doesn't restore Call and Text ( this is the problem) Phone doesn't know your location

then u are having internet only 4g like in a Roaming State.

-Flash or push new Rom same Doesn't restore (call/text)

-Factory reset from a custom Recovery Doesn't restore as well
[HTC Droid DNA] hyphydragon:
to skip the activating screen you can touch the four corners of the screen in this order

top left

top right

bottom right

bottom left

this will bypass the activating screen

once you're in the rom in cdma subscription change it to the other setting, I stopped using that rom so i cant lead you through it

the aosp roms made my screen flicker so i went back to sense 5

good luck

This Sucks Verizon actually exchanged my phone In store considering I don't know how to ruu or what that is I haven't flashed anything on this new phone to afraid of the same **** happening again. Damn! Is this a cm10.1 thing? Or a android 4.2.2 thing? Is it safe flashing sense based roms ? This is kind of a nightmare for me not flashing anything.
[HTC Droid DNA] swiftinmotion:
Was reading around right now seems like other people having same issue I had on cm10.1 and cm10.2.. Think it's safe to flash a sense 5 rom?? Or the same **** happening? Should of just stuck to my gs3 is what it seems =(
[HTC Droid DNA] finanandroid:
You can safe flash NOS_m7_v3.0.2_VZW_zip , if you have TWRP recovery, just wipe normal factory reset, don't do advanced/ system wipe as most guys recommended, never wipe Storage phone people get stuck without OS because erase everything . I Flashed doing just factory reset on TWRP. I recommend wait for AOSP Rom get most stables soon coming leaks from official Verizon Wireless for the DNA/One. sense /GPE edition

RUU is the Factory image /setting original HTC/Verizon for DNA so when you RUU it revert anything to factory out the box phone

The RUU thing you have to read this thread : http://xdaforums.com/showthread.php?t=2293919&highlight=flash+radio

Edit: Remember do always a nandroid Back up first before flash any Rom so you can easy restore your original Rom if something goes wrong.

additional I keep a Original Back up on my Computer.
[HTC Droid DNA] swiftinmotion:
I use clockworkmod safe to use? Never used twrp. And I always make a back up that's what's weird. When I flashed cm10.1 and it couldn't activate thought it was odd so I flashed my back up and that was affected also no activation. Anyways. So your saying if I flash something to wipe data/factory reset but don't go into advanced? Just wipe dalvik?
[HTC Droid DNA] finanandroid:
I don't use CWM by now, but just do data/factory reset and dalvik as well.
