Z4 Tablet battery life demolishes the competition! - Xperia Z4 Tablet General

Now THIS is promising: Expert Reviews have published their Z4 Tablet review, and according to them, battery life actually sigificantly exceeded Sony's claims.
With screen brightness set to their standard of 170cd/m2, they recorded a screen-on time of 19 hours, 48 minutes without even using Stamina mode. Simply put, there is nothing else on the market which can compete with the Z4 Tablet, it seems.

Now this is really promising :fingers-crossed:

That's amazing. Very competitive with iPads and every other Android tablet.

I recieved my Z4 Tablet (Wifi Only) on Thursday During the weekend I could get at least a little feeling about the battery performance. Mainly I installed apps and configured my UI, I also had one HD movie streamed through Wifi.
The display seems to be the main battery eater. During the first charge it had consumed 41% of the battery. Since then I set it to a lower brightness.
The overall battery performance so far feels very similar to my wives Ipad Air.

I have Z4 for a week now. Last full charge was 4 days ago and i still have 15% battery. Screen on time is 8:30 hours (91%). Brightness 100%, adaptive brightness on, stamina on. I use tablet mostly for web and email, no gaming or movies.

I have the WiFi LTE version, is turning airplane mode with WiFi on the best way to shut down cell battery consumption?

Yes, and if you use it with long pauses in between, adjust so WiFi shut down when tablet is in sleep. Do that under WiFi advanced settings. If you only have short brakes, then WiFi should be always on.

Thanks for the tip. It will definitely help.

My battery life is really weak. Without stamina mode i get about 4 hours of screen time with 2 days of use.
With stamina on i can barely reach 7 hours along 3 days or less.
I don´t game on it., just use chrome, feedly and Plex.
The display uses 60-80% of the battery!! Despite I set it at 50% brightness manually!
Anything besides video playing drains the battery pretty quickly, specially chrome (10% every 25 minutes),

The z2 tablet I have managed to get 6 hours on screen time while playing a game on half brightness hopefully my upgrade to the z4 tablet is worthy

For me battery is kind of ok on the z4 tab. But compared to my old nexus 10 it wouldn't have a chance. I was able to get up to 10 hours screen time there with the same usage habbits.

Good grief. My Nexus 10 is barely past a year old, and I can get maybe 2.5 hours of screen-on time, three hours absolute max. Even when it was new, I think it was only capable of five hours or so. It's certainly never been close to 10 for me.

You need to change the title of this post. The battery life on this tablet is horrible and doesn't demolish anything. My personal experience is 5 hours of screen on time with Internet surfing, which is quite consistent with this review:
http://www.trustedreviews.com/sony-xperia-z4-tablet-review-battery-life-camera-verdict-page-3
Quote from the review:
In Airplane mode, with screen brightness and volume at the midway mark, we played a standard-definition video on loop and the Z4 Tablet lasted an unremarkable 5 hrs and 30 mins. That’s nowhere near the claimed 17 hours video playback.

Battery life

Hi all
Here in UK We still waiting for TAB 10.1
very confused between ipad2 or this one
after a lot of reading I've made my decision to buy this one, but the only thing I really want to know is the battery life for this one as it is very important for me
( doing a lot of travelling long distances on the plane)
Engadget said that its battery lasted above 8 Hours of video loop while others said it lasted just above 5 hours.
I know that the Tab cannot beat the Ipad2 when it comes to Battery, but I am still buying the tab10.1 if its battery lasts 1 or 2 hours less than the apple product.
Could you please -who own this item- let me know how the battery life is?
Many Thanks
i just received mine the other day. i let it charge overnight.
i then used it for just about 9.5 to 10 hours and plugged it in when the
battery meter was at 15%.
the battery life is excellent !
it really depends what you are doing on it. I use it throughout the day but primarily while at work to keep my sanity (I work overnights). I watch loads of HD youtube videos and the browser since my office thought it was cool to put website blocks and disable flash (for youtube blocking) so to see videos on sites or actually see full sites the tablet is crucial. I tether the wifi from my HTC Thunderbolt for access. I do also play some games. I can get through my 8 hour day with about 50%
Edit
based on pandamaja's response below, I didnt actually touch the screen brightness so that means it is working harder to auto adjust itself according to the brightness it is in
Battery life so far has been excellent. I don't travel as much as I used to, but I can see this thing lasting for a good while. Like others have mentioned, it depends on usage.
The display is going to be the single largest battery drain. I'm not sure about the 'others' tests, but the tests done by engadget and apple are done with the display brightness set at 50% I believe.
I've been very impressed with the battery life so far. My Evo basically lives next to a charger. Before I went to bed last night I considered not even charging the tab.
So far so good for me. I haven't timed it but I have been using the tab on and off for a couple for days before needing to charge it.
I do keep the brightness level pretty low.
I have had my tablet on since I bought the device. I charged it for an hour after playing with it, and have watched 3 hours of TV shows, and when I have not been using it, it has been idling (for 4-5 days). The battery was at 37% when I finally plugged it in last night. This tablet's battery life is the best battery life of any device I've ever owned.
pretty much been having the same experience as everyone here. i've gone through 2 days without charging (currently at 47%), and this is with browsing the internet, watching videos, and playing games. depends on the display brightness and usage. i have mine set at about 50%, as i find that plenty sufficient.. this panel gets bright. the tab also holds charge real well when in standby.
Thanks for that, very helpful
any one has set it on video loop with reasonable brightness (50% i guess good)?
How long can u get?
the reason I am asking because I am flying quite regularly to mexico ( 10 hours) and mostly watching movies
any help very much appreciated
Many Thanks
how did samsung even manage to squeeze that amount of juice in?

Hey OP
I believe that most reviews for the tab says it can play ~10 hours of video using 65-70% brightness. I've read at least 5 reviews having similarly result. Only one review got 5 hours of video. I would doubt that review.
FYI, the ipad2 gets 10.5 hours under 70% brightness playing video.
I got my tab yesterday. I played video for about 2-3 hours, using 70% brightness, and baterry went down ~30%. I would say a 10 hour video playback seems to be correct.

Battery life

I got a refurb Note 10.1 2014 from Groupon about a month ago. The battery life has been poor but I didn't use it enough to quantify it. I got home form work today and it was at 65%. After exactly an hour of use, it told me it was about to die at 5%. I can literally watch the battery percentage tick down while writing an email or browsing the web. Is this normal? I've had 11 android phones but this is my first tablet, I've never seen performance this poor.
This is my issue with android devices. If you are not an above average user and know how to trouble shoot to find what app or apps is causing your battery drain you will be left thinking the device itself is not good, when it's probably a wakelock or some background app killing your battery.
My device has good battery life. I wish it would do better with simple Internet browsing, but watching videos and other tasks are great in my opinion.
My advice, try to find if your issue is software related. After ruling that out, the only option is that out must be hardware related.

I found the battery poor for the first couple of weeks. I gave it a full charge, took it off a couple of mins after 100% each time, only letting it drain down to about 15%. I was getting about 6 hours on screen time without power hungry games.
Then a few days ago drained it full, and charged it over night, now getting 9-10hours on screen time - mainly web surfing, watching full hd film streamed off home servers and low power games (5's.....far too addictive and simple). This also includes some use streaming bluetooth to wireless speaker with screen off, so at least another hour use on top of the 10 but with the screen off.
I'm about like redsurf. 6-10 hours of screen-on depending what you are doing with it. If you are only getting 2-3 hours there is something wrong. You can check under power in the tools/settings menu to see what is eating your power. If it is a program, kill the task. If it is the screen (more than 50% any time I have checked) and you are only getting 2-3 hours, definitely something wrong.
Oh, also try turning down brightness.

Funny enough, I probably have my screen brightness set to between 10% and 25% and rarely ever need it to be turned up any higher than that.
By rooting and disabling alot of bloat stuff I get an additional 1-2 hours out of my note 10.1. Just saying
I'm sure there could be a software issue, but even if i was gaming at full brightness with 40 background apps (I don't), 2 hours is unacceptable and probably defective.

Battery life struggles

Is anyone else struggling to get more than 3hrs screen on time in a 12 hour day. I don't game or watch a lot of videos. It seems like the phone isn't going to sleep when I'm not using it. Just testing the waters if my unit is defective. I mostly web browse and read stuff on g+. My screen brightness is a little less than half with adaptive brightness on and enhanced voice over lte is disabled on Verizon. Thanks for the help.

3 hours of screen on time seems pretty good for a phone with a screen this big and with brightness around half way up. Is 3 hours SOT bringing you down to like 0 battery?
What do your battery stats say that make you think your phone isn't sleeping?
I only really tested the battery and checked the stats twice and I think the second time I had 2.5 hours of SOT over the course of 13 hours and my battery was at about 38% (also on Verizon).
I think that is pretty reasonable. If I could get 4 hours of SOT from full battery until dead I would be fine with it. Others have been posting much longer battery lives though.
I have read on this forum that one person tested the phone with the screen looping a video at full brightness and it lasted over 5 hours. http://forum.xda-developers.com/showpost.php?p=63642067&postcount=391
Some people are showing screen shots of over 5 hours of SOT http://forum.xda-developers.com/showpost.php?p=63690175&postcount=462
Off charge 23 hrs ,been using mix if WiFi and 4G all day and some poor signal areas
Do you have your bluetooth always on?
No never on unless I need it ,have WiFi on all the time and toggle mobile data on and off as I need it
Yeah my mobile network signal is mostly orange and red. I keep Bluetooth on all day for my smart watch
See it is awake all the time I made a long phone call today so I can't judge the battery today.

I found my moto 360 was keeping my phone awake (possible bug?). so I disconnected my watch and the phone actually slept when the screen was off! Give it a try!
I just have a pebble but I'll give it a try.
At 2 hours in 13 mins screen on time. Phone seems to be sleeping now but there is a bug in my battery stats. Any clue?
Here are the screen shots
Still not impressed. The phone isn't staying awake now that I disabled Bluetooth but isn't going to doze. I have purposely tried not to use my phone today.
Battery is terrible. I'm hoping once some new kernals hit it gets better... Because right now I'm thinking of returning this thing.

I used the phone heavily at work my first day with it and from 7am to 10pm I still had 40% battery left. I'm impressed with this phone.
This post will be taken down soon as there is already a dedicated post available but I get amazing battery life like 6 hours easy. I would suggest an RMA. Plenty of individuals/reviewers have commented on the performance of this phone's battery.

I am not sure why people keep complaining about BT on. I leave mine on all the time. Although i don't use my smart watch any more, so it is only connected in my car and my BT speakers at home when I want to listen to music in bedroom or so. I don't have any drains. I get 4-5 hours SOT in 24 hours. This is a first for me always owning nexus in the past. I am very happy. I also started testing the force doze mode on screen off setting with greenify today. It is making standby noticeably even better.
First day with pretty heavy use. The best battery I've had in a phone.

Install gsm battery and find what is sucking it down.
I bet anything those having battery trouble have apps syncing in the background like facebook, email, etc. My phone has been of the charger since 9am it's now 1am I have 2:20 sot with 58% battery left

While I don't believe you would get that amount of SOT over a prolonged period, it does point out that raw mah isn't everything.
I agree it won't get that much in real life. I am curious however how the SOT will be for people that will not use the radar, no AOD and possibly even no face unlock, stay on 60hz and just want a great camera, good speed and latest assistant and have the best Google ecosystem experience. I am that kind of user.
I looked at the 3axl but it is noticeably slow and I need a fast phone for different work needs.

no doubt, those conditions that you just stated should save a substantial amount of battery life. My 6T is 3700mah and I get around 6-8hrs sot(depending on usage) no reason to think the pixel can't achieve that with superior software.
Got the phone yesterday, charged all the way up before turning on at about 5pm. Went to bed about midnight. Galaxy S2 watch connected around 7 pm. Did setup, some netflix, and typical messing around with a new phone. Didn't screen shot it, but when I was going to bed last night, I had 4h03M SOT with 47% left. I don't expect it to translate to 7hrs or anything, but it seems better than my previous Note 9 and S8+.

Roger that on the N9! My wife's N9 looses a minimum of 10% overnight at idle. Shoot, my Chevy suburban with 6 people going uphill at 75mph gets better mileage! ???
I got the phone yesterday and charged it too 100% and my screen on time was 6hrs 5 Mon with 9% left. I don't get why the negative battery comments and reviews so far. 6 hours is more than enough.
First cycle with dynamic 90hz no point of forcing always to 90hz. Most social media apps. Tg and duo suck a lot of battery.

The battery is not that bad... here are my screenshots. I am not a gaming person but I usually was surfing the internet, Facebook, etc... and use message app and did use the camera. I turned motion sense off since I am Deaf so I can't hear the music and my hands are getting tired from wave and wave.
sorry for bad grammar.
Good. Maybe the haters will STFU now
Got my 4XL yesterday and it was at 60% out of the box. I used it like normal and with more than 3hr 30min of screen on-time it was at 24%. I don't think it will be that bad.
2nd cycle I guess since it's under 75% it was at 60hz didn't notice any difference screen still very smooth.

I believe they meant the screen brightness was under 75%. When it is, the screen only runs at 60hz.
So I've had the Pixel 4 XL , for 3 full days in the UK now.
Day 1 SOT was 6 hrs 3 mins with 9% left
Day 2 SOT was 6 hrs 15 min with 4 % left
Day 3 SOT is 5 hrs 1 min with 18% left.
The battery is more than adequate. I had the 3 XL which would get a max of just over 4 hours. I'm new.to the forum but I have screenshots as well but don't have a clue how to upload lol. The phone is on 90hz at all times too But most times you can't really tell. It's an amazing phone so fast, the disappointment is video quality again and some of the pic quality is similar levels to 3 XL but I need to fully utilise the camera.
I got similar SOT with 6 hr 12 min and 9% battery left. This with using "force" 90hz , 87% brightness , and always on display (thought it was not always on!). Battery is more than adequate for my usage.

I'm a bit disappointed with the SoT figures I'm getting. I would've expected 5 hours a day with at least 25% battery life left. However I'm roughly getting 4 hours by the time the phone hits Stamina mode.

You should be definitely be getting more.
I usually get 6.5 to 8 hours SOT on my Xperia 1 II. So you should be definitely be getting more than that
This is very strange. I am getting 8-9 hours of screen on time within 1-2 day usage. Try to disable everything you don't use (all the Google data collection and other ****) and see if it helps.

Same.
My Poco F1 with LCD and bigger screen has a better screen on time.
Something is fishy here, I'm using DarkMode and a low background light.
Which Software you guys are using? Mine firmware is: 58.0.A.10.21
I think it has todo with the Vodafone branded software.
58.0.A.12.23
So it is not an old Firmware issues. There must be something hardware related issues.
Does your phone also get warm while using it?
When I browse through Google News (WiFi) it gets noticeable warm.
I am happy with my battery life - fully loaded 2 days ago, now at 28% after 6h30m Screen on time.
Mine get 7.5 hours. Pretty satisfy with this phone.
I'm getting about 6 hours sot from 90% to about 19%. Not as good as I expected.
Edit: above usage with 120hz setting. For mine, the SOT fluctuates. On one of the days, the SOT was only 4hrs. Trying to find out what's taking up the usage.
It would be helpful if you write if you use 60 or 120 hz.
Battery life on 5 II is very good, SOT, 7-8h, aprox.30+hour.. 120Hz

Wow, that's a big difference. Really got to find out what's using the battery on mine.
Is now at, 46%, 28hrs, 5h8min. 120Hz. Not bad sony, not bad.
Moderate use (some calls, wifi/3g, browsing, yt, etc.)
Some SS
More screenshot
thats crazy screen time, how does your google play services say only used for 25mins?? for me today google play services has been used for 7hrs25mins so far and its only mid afternoon i have no idea why its always on...even though google play services only uses up around 4% battery each day for me it always says used for around 10hrs each day, any tips on how i can get mine down to a respectable 25mins like yours?
Sony phones has some miraclemagic in their batteries, very good results indeed. I tested last two cycles, first with 120hz and another one with 60hz.
120hz: 100-1%, 9h 30min SOT during 41h time period.
60hz: 100-1%< 11h 36min SOT during 48h time period.
Mostly on wifi at home, lot of videos, social media and web surfing.
Power consumption at idle state is the best. I have had 4 mornings in a row with the same battery percent that was last night. 0% consumption during night. Gotta love it.
Very good battery life, with 120Hz enabled.
Do you guys actually use the "Battery saving mode" function? You know that charging the battery to 100% and discharging to 1% slowly kills the battery lifespan? That's why Sony developed this technology, so why not use it? I have set mine to 80% and charge my phone every day so my battery never goes over 80% or below 20%...
