Bought a Z Ultra about a week ago. This is my 4th charging cycle. Battery improving a lot...
[Sony Xperia Z Ultra] Tommy-Geenexus:
Gaming only.

Good battery life, notice the cpu has never downclocked due to ultras thermal aesthetics and speed bin 2.
[Sony Xperia Z Ultra] hanifh:
excellent battery life. 6hrs of SOT is unheard of for me whether stock or custom ROMs.
[Sony Xperia Z Ultra] H. E. Pennypacker:
It greatly depends on usage and the types of apps installed, so you won't come near those kind of times if you play a lot of games, for example. If you read a lot, however, you will be able to push it up to 8-9 hours SOT. Not that hard considering the CPU will be mostly idle at 300 MHz, and the GPU will pretty much be on vacation the whole time :silly:

Also, it's pretty darn hard to use a smartphone for several hours a day, especially more than 4-5 hours, but it's nice to know that the battery won't die on you if you're stuck somewhere without a charger.
[Sony Xperia Z Ultra] Tommy-Geenexus:
can't complain :)

Medium usage with a bit of gaming and mostly browsing and such.
[Sony Xperia Z Ultra] dadme:
What rom and kernel?
[Sony Xperia Z Ultra] Tommy-Geenexus:
look @ my sig ;)

SlimKat and my Kernel.
[Sony Xperia Z Ultra] manav_patial:
More than 4:30 SOT with heavy usage on 3G network...unrooted....really good..
[Sony Xperia Z Ultra] Gschisi:
This with an brand new Battery. I think it should be more?
[Sony Xperia Z Ultra] blueether:
Maybe, what else were you doing?

Lollipop not quite there yet...
[Sony Xperia Z Ultra] Gschisi:
Only Browsing, Whatsapp, Facebook but no Gaming
[Sony Xperia Z Ultra] blueether:
Whatsapp and Facebook may be the problems
[Sony Xperia Z Ultra] Gschisi:
But when i cant use Facebook,Whatsapp and so.. Why i should use a Smartphone?

Sorry for my bad English
[Sony Xperia Z Ultra] alia5:
facebook is a real battery hog...

theres an alternative facebook app called fast, i'd suggest you give that a try

also you can use your webbrower to acces facebook just fine
[Sony Xperia Z Ultra] blueether:
I'm sure I posted the same thing

ho hum, into the ether it went... never to be seen again
[Sony Xperia Z Ultra] kucing2k:
Using scrubber's GPe ported rom on my C6833.

Spoiler content hidden.
[Sony Xperia Z Ultra] hanifh:
whoa! thats some epic battery life. Its tougher than winning the lottery to get over 12hrs uptime and 4hrs SOT here! (on the same ROM).
[Sony Xperia Z Ultra] frothe3:
Just took from my ZU, have for about two weeks, brand new from Sony.
[Sony Xperia Z Ultra] blueether:
GPe with very light use (yes that is 13 days up time)
[Sony Xperia Z Ultra] Apocalypse Now:
Official 4.4.4 , build 108.

6 hours and 12 minutes of On screen time. mostly low light screen but having Wi-Fi on continuously :)

hope it gets better on Lollipop.
[Sony Xperia Z Ultra] xswxm:
I have delete all the Google Apps and some Sony Apps or Services, and it's really power saving.
[Sony Xperia Z Ultra] Narvarr:
My battery life sucks now with the 5.0.2 update. Makes me want to revert back to Kit-Kat.
[Sony Xperia Z Ultra] shadovraven:
Kitkat here, moderate to heavy use (sms, calling, internet browsing, bit of YouTube and games) for two days.
[Sony Xperia Z Ultra] brosenz:
Yes, I was mostly discharging the phone
[Sony Xperia Z Ultra] avsquare:
ah I see. I thought something went buggy.

There was once the battery management failed to show the screen usage right from the start and only showed up after me surfing the net over 1hr from 100% battery. And the screen time started from 0 lol. Which means technically when the total up time says 1hr, the screen time should also say 1hr but it says 1s when it showed up lol.
[Sony Xperia Z Ultra] mobile-freak:
Hello did someone used ZU with Bluetooth headset. For me it is also important to see how long the battery will stay with it.
[Sony Xperia Z Ultra] Tarzan-:
I used it for about 1 hour and looked fine to me.
[Sony Xperia Z Ultra] rockmaster:
This is mine after 8th cycle. It's getting better compared to first 5 cycles. Well have to say it's impressive to a phone with big screen. No problem and give up the idea switching to butterfly S. Now only wait for update to enhance camera.
[Sony Xperia Z Ultra] aaronqui:
Hi Rockmaster,

How were you able to get battery life like that. It seems my battery drains so fast while on standby. This is only my 3rd charge since i got the phone. I have downloaded better battery and have some photos to upload.

Hopefully battery life will get better. Because as of now, it seems to be weaker than my galaxy s4, and i was hoping for it to last as long as my galaxy note 2.

Thank you,

Aaron
[Sony Xperia Z Ultra] clubtech:
Yes for me too, battery drains super fast when in sleep mode. I checked for wake locks, nothing special pops up. This must be something in the firmware. hopefully it will be get fixed with a software update.
[Sony Xperia Z Ultra] aaronqui:
Thank you for your response. However you were still able to get over a day of battery life while I seem to only get 14 hours with around 3.5 hours of screen time not playing any games.

Ill wait for about a week then post my better battery stats don't get any better.

Thanks again
[Sony Xperia Z Ultra] rockmaster:
Dear all,

You can try to update to newest firmware 471 and see improvement in battery life. Like I mentioned in my post, it sucked before with 5 cycles or less, only see improvement since 8th cycle. Am now on my 9th. Will send you guys screenshot on 10th later.

My settings:

-Auto brightness with minimum auto.

-Stamina on.

-3G mostly, wifi sometimes.

I mainly use phone to surf web, xda, viber, sometimes texting and calling. I also play games like Ray man Jungle Run, Candy Crush.

Give it time, after a few more cycles you would see some improvements. I could only get 3h30 previously :laugh:
[Sony Xperia Z Ultra] mozzy:
That means nothing without screen time screenshot
[Sony Xperia Z Ultra] mcteague:
Sorry mate its only 2h44m, but as for simple standby its way better than my original Galaxy note.
[Sony Xperia Z Ultra] aaronqui:
Dear all,

I've actually updated to the latest .71 firmware. Well ill see after a week and hopefully the battery gets beetter. I'm using zero brightness also. Maybe eventually it will get better.

Ill update after a week. On the otherhand how great is this phone eh. I thought the note 2 was going to be my ultimate most favorite phone, but this one is way better.
[Sony Xperia Z Ultra] zoomm:
abnormal ,screen consumed 80% of the battery life

Battery life suck!
[Sony Xperia Z Ultra] zergslayer69:
From what ive gathered reading through the various threads the sleep time on this phone is better than note 2 but actual active usage with screen on is weaker than note 2. How long can you do a video loop before battery dies? Supposedly the note 2 can go on for a fairly long time. (I keep saying note 2 because that's what I own now and will probably be disappointed by note 3 screen size)
[Sony Xperia Z Ultra] Blacklighter11:
My batt life is superb but I am only comparing it to ip5,stand butterfly.
[Sony Xperia Z Ultra] mobile-freak:
With STAMINA or without STAMINA MODE?

Same Question here, With STAMINA or without STAMINA MODE?
[Sony Xperia Z Ultra] corrado85:
i cant believe this so called sh1t "STAMINA" mode actually benefits unlike my previous phone "Power saver" mode.

been using my phone moderately for music/email checkin/browsing/whatsapp/calling a little

and after 11h 23m 56s, I have 56% left

un-ba-leee-va-bal
[Sony Xperia Z Ultra] mitsosoft:
Average usage with STAMINA ON ;)
[Sony Xperia Z Ultra] danilos2k:
First charge, I m using it like a tablet not a phone

Here is my battery usage. :)
[Sony Xperia Z Ultra] pandurang_m:
My Xperia Z Ultra battery usage.
[Sony Xperia Z Ultra] LordManhattan:
So, all in all it looks like the ZU battery is quite good actually. I believe it can be even better if Sony optimizes the kernel a bit more though. I haven't received my ZU yet, but looking at these times and numbers it looks like it's better than my current Galaxy Note (using a new-ish battery).
[Sony Xperia Z Ultra] Etienne38:
Huuu, I do not agree with you, because we see here battery usage with only screen on, or maybe a little facebook or mails.

I am using as well the Galaxy Note, but I am playing with games, surfing the internet via wifi and 3G, reading my mails with 3G, taking pictures, and with that usage, I can start the day with a full battery and end the evening with the battery close to zero (but the usage is really extensive).

So I would be very curious to see battery usage with mails/internet/games/video applications :angel:

Then, we will compare (and I hope that the sony will be really good, because I would love to replace my gnote with it)

But if you play two hours and battery is drained, then I will probably look to other 6 inches + s-pen devices with better battery (asus fonepad note 6 or alcatel one touch hero)
[Sony Xperia Z Ultra] DakiX:
Omg i got it :D It is a great smartphone, battery life seems to be quite good. The QSD800 has a lot of power but is also energy efficient. Yours screenshots are partially incredibly good!
[Sony Xperia Z Ultra] pandurang_m:
My day is done. Getting charged with my Xperia Z Ultra. Awesome backup with tons of usage.
[Sony Xperia Z Ultra] golfinggino:
depends on which galaxy note you are referring to - if the orginal one the ZU is way better battery life - if comparing to the note 2 - i would say it is pretty close - i sold my last note 2 yesterday ( had 5 or 6 of them ) probably the note 2 lasts a little bit longer
[Sony Xperia Z Ultra] SpyderTracks:
Mate, this phone smashes my old note. Even when I bought a brand new battery, on lsz stock I barely managed 9 to 5 without recharge. This thing has 40-50% after a 15 or 16 hour day and I use it a lot!

On a separate note, my data usage is much lower after using it a week, will have to monitor further. Love this phone to bits, exactly what I'm after!
[Sony Xperia Z Ultra] SpyderTracks:
Battery usage (stamina mode on)
[Sony Xperia Z Ultra] SpyderTracks:
Screen on
[Sony Xperia Z Ultra] LordManhattan:
I'm referring to the first Note. I'm hoping to get the ZU tomorrow or on friday (ordered it yesterday)

That's really reassuring since it's been a while since i had a device with a sealed battery (iPhones), and i'm kind of used to replace my battery if it's ****ty. It's reassuring to hear that it's as good, or better than the Note's battery. How it'll perform down the road is something i don't want to think about right now though :p
[Sony Xperia Z Ultra] Etienne38:
It is great to hear that feedback indeed, I agree with you.

I cannot wait to read your feedback as well :)

Have fun with that great phone !
[Sony Xperia Z Ultra] golfinggino:
there is no comparison on the battery life between the original note and the ZU - the note 1 did not have a good battery life - plain and simple i had a few of them a long long time ago - rooted / undervolted, etc. and it is about half of this phone - the note 2 is another story it is currently has the best battery life of any android phone that i have used but the ZU with all the updates and set up properly is pretty close - i have owned 3 galaxy s4's tryied and really wanted to get the battery life to be acceptable but i dont think it is possible that battery on the s4 is really bad - sold them all after using them for less then a week and will never buy one again - i learned me lesson !!
[Sony Xperia Z Ultra] infernus70:
Now tell me if the battery is not good. ;)
[Sony Xperia Z Ultra] Etienne38:
WOW this is G.R.E.A.T. !!!

Thank you very much, it is impressive, indeed !

I cannot wait for that wonderful phone to be sold in Belgium !!!

thank you all of you for your feedback which are VERY useful for us to make the choice without being disappointed :) :good:
[Sony Xperia Z Ultra] troed:
To make a long story very short:

Ordered my ZU last Sunday at Amazon. de, was delivered on Thursday, unpacked it, loaded batt to 100%, started to configure it to my needs. 64 GB mSD from my Galaxy Note 10.1 inserted, was recognized immediately, all data (48 GB of photos, movies, teaching vids and docs) fully readable.

Settings: BT, 3G/HSUPA on at 5 bars , NFC on, GPS on, screen brightness 50-100% (to check readability in strong light/sunlight)

screen was constantly on and I was constantly downloading one by one my first 40 apps, checking if they work, in between listening Manfred Mann's Earth Band (local on SD card) and Jethro Tull (stream from Amazon cloud player).

I got 5hrs 36 mins until 5% batt was left.

Today I proceeded the same way with the rest of my 140 apps. This time I went down to 2% battery left and had to plug charger after 6 hrs and 39 mins.

Summary:

This device is perfect and flawless, no single hickup, blazing fast and responsive.

Compared with my now retired Sammy Galaxy Note 10.1 (I use it now as remote for my Sammy TV, as Book Reader and Videoplayer/streamer) at the same workload the ZU lasts longer.

Compared to my Galaxy S 3 the screen and size is much more comfortable and the look more elegant. This is why also my S 3 will retire in two weeks when my Xperia Z 1 arrives:D:D:D

Xperia UI is more logic and comfortable (for me) than Galaxy UI (I liked it from the first moment), Sony apps work as good as Samsung apps.

I am still waiting for my DK 30 dock and hope on the availability of Sony CP12 battery cover soon to have full juice on intercontinental flights of 12-13 hours.
[Sony Xperia Z Ultra] Etienne38:
Thank you VERY MUCH ! This is actually a VERY nice report and of course, this is 6 hours of VERY intensive usage, and especially with the battery not yet to its full capacity (because brand new), this is a excellent clue that the battery autonomy is really good and we don't have to be afraid of that point when considering to buy that phone !

Again thank you !!!
[Sony Xperia Z Ultra] DakiX:
2d and 12h running, 4h and 22m Display-on and still 38% :good:
[Sony Xperia Z Ultra] AntiLazarus:
The battery on this phone is pretty good. I didn't take any screenshots, but a couple days ago, I used the phone almost constantly on my 2 hour break between classes (all web browsing, by the way, mostly on the New York Times app), and by the end of the school day had lost 35% with a little over two hours of screen on time. About 45 minutes of that was outside, too, so screen brightness was very high. This also doesn't count time spent listening to music via Bluetooth, which I would estimate I did for about 30 minutes.
[Sony Xperia Z Ultra] ScottishSwan:
Here is a screenshot I took from my screen on time.

Had more than 1 day of standby and more than 6 hours of screen on time. This to me is perfectly fine for a phone of.this size and a screen this big.

My Z Ultra gets me through the day easily. Most days before I go to sleep I have a 50% charge left after what I consider to be heavy use so 2 days with it should not be a problem :)

Thanks
[Sony Xperia Z Ultra] pandurang_m:
Normal usage with little browsing and messaging.

Day by day the battery gets better and better.
[Sony Xperia Z Ultra] ScottishSwan:
Screen on time?
[Sony Xperia Z Ultra] troed:
Addendum to my previous report:

Yesterday I streamed two full HD vids via HSUPA. I started at full charge and ended after 4h 21 mins with 31% battery left.

Quite good for me .......................

The same with Galaxy Note 10.1: 12 % battery left
[Sony Xperia Z Ultra] cholepuree1:
What was your brightness level set to?
[Sony Xperia Z Ultra] IsolatedAbyss:
Coming from a Note 2 and using ZU for two weeks, I have to say the standby power drain is excellent and much better than Note 2. However, when it comes to intense use like 3D gaming and watching 1080p videos, the battery plummets very fast so in actual use, my Note 2 fares a tad better.

Overall, if you're a light user I think the battery life can be fantastic. I can still edge out a full day of use on the ZU most of the time so the battery is only satisfactory for a power user like me.
[Sony Xperia Z Ultra] baileyjr:
I agree, I've come from a note 2 which had a 9000mAh zerolemon battery attached lol

The standby time is excellent. I'd have no problem draining it from full to 30% with a couple of hours active use, but its comforting to know I can them switch it into stamina mode and know I can make it through the rest off the day if I just want to take calls and texts.
[Sony Xperia Z Ultra] LordManhattan:
Here's my battery usage. I got my Ultra yesterday, used it out of the box from 60% down to 20% before I charged it up to 90%. That was about 16 hours ago, and let me just say I'm very happy with battery life. I'm positive that I can get at least another hour of screentime, or even more out if it
[Sony Xperia Z Ultra] LordManhattan:
God damn it XDA. The app is trolling me. Here's my current screentime
[Sony Xperia Z Ultra] SpyderTracks:
Mate, glad you got it and are happy with the performance.... Sweet phone huh!
[Sony Xperia Z Ultra] LordManhattan:
It's a very sweet "phone" :) Still not used to its size though, but i'll get there. Got around 5 hours screen time and 17 hours uptime before i plugged it into the charger, and that was on my second charge! This might end up as a good investment!
[Sony Xperia Z Ultra] fanxiang83:
Here is mine. Looks pretty standard.
[Sony Xperia Z Ultra] LordManhattan:
Yup, looks normal to me :p Funny isn't it? A couple of weeks ago people were raving about sick screentimes at 4-5 hours, and now it's "totally normal, dude" :p
[Sony Xperia Z Ultra] marcgear:
Damn right I getting 3hrs max on my z can't wait to get the Times shown in this thread lol
[Sony Xperia Z Ultra] jefefe:
i turning on Stamina mode but with the exclusion of Whatapps, Line, Skype and Google Serivce..

I have to say coming form a iphone5 user, this guy has better battery..:laugh:
[Sony Xperia Z Ultra] iron59:
averaged of 4.5 to 5 Hrs screen on time and 10% to 20% left daily, is that normal or good ??
[Sony Xperia Z Ultra] LordManhattan:
I wanted to kill my battery yesterday since I'm used to charge it around 16:00 (4 PM). I got around 4 hours 30 minutes after raping it all day with music, some video, A LOT of reading etc. Unplugged it again 7 hours ago, and have currently 81% left with 1 hour 30 minutes screen time.

---------- Post added at 01:41 PM ---------- Previous post was at 01:39 PM ----------

That's good :p
[Sony Xperia Z Ultra] aungkhaingoo:
How can i control cpu usage to extend battery life.
[Sony Xperia Z Ultra] vanadium101:
In the last two days working where there is no reception, the phone only dropped to 80% battery between 5:50am and 4:00pm with 7.5 hours being with zero reception. :laugh:
[Sony Xperia Z Ultra] wookie_666:
Picked mine up today and as you would guess with a brand new phone . Have not put it down. Had the screen of death once and have rooted it to try to make the speaker louder but have not gone any further than that.

Well it will not let me post attachments so I have 4hr 16m usage with 23 percent left70 percent usage by screen. .
[Sony Xperia Z Ultra] Etienne38:
Great, and which luminosity settings did you use ?
[Sony Xperia Z Ultra] cholepuree1:
Thats what I'm interested in as well. What do you all use for your screen brightness? I get around 3 - 3.5 hrs of screen time, but keep it on full brightness, and NO stamina mode..
[Sony Xperia Z Ultra] LordManhattan:
I have it at 50-100% during daytime and 0% at night. I get around 4-6 hours of screentime depending on usage.
[Sony Xperia Z Ultra] Safar_Ibrahim:
My usage
[Sony Xperia Z Ultra] blueether:
On the first charge I got just under 5 1/2 hours of screen time with the screen at about 75% - also had wifi / gps / video etc on at times. Quite impressed.
[Sony Xperia Z Ultra] LordManhattan:
Last results: 6 hours screentime, 18 hours uptime. Surfed the Web as usual, playing Riptide GP2 and read a lot. Overall mostly reading stuff, so no CPU heavy activities except for the gaming.
[Sony Xperia Z Ultra] tommo123:
so overall then the battery is ok? i'm mostly sold on the ultra to replace my note 2 and i'm hoping it would handle my usage habits. my note 2 can have HSPA+ on all day with facebook, bbc, weather, guardian and others apps updating every hour, screen always on 100% brightness, stream via google music, check mails, some bluetooth time (for music and a heart rate monitor) on a 2 hour walk home and i'll still have above 50% battery left.

granted my area will soon be LTE which i think uses more power than 3g so wondering if the ultra could handle that? or would i need to get something like the CP12 cover?

cheers :)
[Sony Xperia Z Ultra] marcgear:
More than happy with mine to be fair.
[Sony Xperia Z Ultra] LordManhattan:
Posted my latest time in a different thread earlier today, but I'll post it here too since it belongs here.
[Sony Xperia Z Ultra] SpyderTracks:
How the hell did you manage that? Stamina? Brightness? Any other tweaks stand out? Have you finally rooted?
[Sony Xperia Z Ultra] LordManhattan:
I'm rooted, but still running stock ROM. I don't reach 7+ hours every day though, and it really depends on usage. I spent a lot of time reading an ebook yesterday (using Readmill), played "Wargames" for maybe 20 minutes, and the rest is browsing and stuff like that, so not really any CPU intensive tasks.

- Stamina: ON (Whitelisted apps are: Spotify, Dropbox, Messenger, Gmail)

- Brightness: 50-100% during the day, and 0% at night

- ROM: Stock 532

- Launcher: Stock

- System apps removed: A LOT

- WIFI: ON 24/7

- Bluetooth: OFF when not being used

- GPS: OFF when not being used

- Auto-sync: ON 24/7

Mods:

- Xposed: App Settings, Adv. Power Menu

That's it i guess.
[Sony Xperia Z Ultra] SpyderTracks:
Thanks for the info.... I'm still getting good battery without any tweaks but I can feel the darkside rising... There's a flash coming!
[Sony Xperia Z Ultra] LordManhattan:
Haha, i actually thought about doing it yesterday when i was bored, but i didn't. I'll definitely do it in the near-ish future though, but I don't see why i should do it now since everything is working well.

(I get quickly bored though, so it might even happen in the next five minutes.)
[Sony Xperia Z Ultra] soncarl:
What do you think the battery life of my phone?
[Sony Xperia Z Ultra] forger7:

[Sony Xperia Z Ultra] LordManhattan:
Looks like you played a fair bit of Clash Of Clans, so it looks OK. You can do better, but it's not bad.
[Sony Xperia Z Ultra] Johnmcl7:
Before I read this thread I would have said I was disappointed with the batterylife but when I actually looked more closely at my usage I see I'm using the screen a lot more than I realised which understandably is going to hit the battery. I was going to get a DK30 and just keep the phone topped up during the day but I'm concerned the effect that's going to have on the battery longterm given it I can't seem to find any information on replacing the Z Ultra's battery.
[Sony Xperia Z Ultra] LordManhattan:
Almost 7 hours of screen time is very good. The screen time will depend greatly on usage though, and if you play a lot of games for example, you can't expect much more than maybe 3 hours of screentime. If you do a lot of reading and stuff that doesn't trottle the CPU that much, you'll get 6-7 hours, but as you may understand, it's really hard to tell these things.

Replacing a battery might be expensive? I have no idea since i've never replaced a battery that's sealed in, but i had great experiences with the iPhone 3GS' battery, and it held up until i sold it, and it's still in use today (as far as i know). My HTC Desire HD doesn't have a sealed battery, but i haven't replaced it since i bought it in 2010 (or something like that), and it's still going "strong". I'm getting a full day of light usage out of it. The Galaxy Note (1) is a different story though. The quality of its battery is incredible bad compared to the other two i've mentioned.

Like you probably understand, it's not possible to tell if the Ultra's battery will hold up well down the road, and we can't really tell until next year when we might see some degradation :) Until that time comes, enjoy it!
