I don't know how sony managed to screw the battery life on the Z1, that battery is huge and yet it underperforms, I hope history won't repeat itself with the Z2 :crying:
[Xperia Z2 General] chesterr:
It is the screen, the best example is the Xperia Z1 Compact. it's doing a good job with 6hours of screen on time.
[Xperia Z2 General] Mano1982:
I don't think it's bad :o I don't own Z2 (I have ordered from ebay and it's on the way), but i own a Galaxy Note 3 which has a really good battery. But whenever i stream a video at night in my bed (in dark), with screen brightness to 0 (to avoid the light hurting my eyes), it still drains 5% in 30 minutes. And whenever i travel from my home to city centre, it takes almost half hour and i always listen music, check my facebook, twitter etc and in this half hour, battery falls to around 90%. I find it quite good.
[Xperia Z2 General] solwretep:
Lol. Thats EPIC battery life.. No worries

Ive charged this ONCE since Friday, the initial and its just now at 28%. Mind you not as heavy user as others but this is double what I got from Note 3.
[Xperia Z2 General] chesterr:
This guy says HTC M8 does a better job but I don't believe it cause I can see the user's usage cause it's stunning.

On KitKat (as far as I know) BBS can't access the battery method any longer, so without root you can't get any informations.

EDIT: read this --> http://repo.xposed.info/module/com.gsamlabs.xposed.mods.enablebatterystatspermission
[Xperia Z2 General] Haldi4803:
..... you CAN get information. You just don't get the Screen dimmed, medium, dark but only Screen On information! At least as far as I could test.

If you have Root just install it as system app. And all works fine again

:) p.s don't you need root for xposed?
[Xperia Z2 General] Paperinik68:
All is well

Since performing my repair and doing a manual installation of all the software I really wanted, my Z2 has been performing quite admirably, considering how much time I have my grubby little hands on it. Yesterday I must have had a good 8 hours of screen time, with watching a movie and streaming music and still had 22% before going to bed at 11pm, this from the morning charge. Normal usage would have easily gotten me 24+ hours, but you guys know how it is with new toys.
[Xperia Z2 General] chesterr:
So then is that guy at recombu retarded? cause he clearly mentions that the winner is hTC One(m8), which I really don't believe him.

BTW did you happen to take any screen shots?

Yesterday's usage. Was on mobile data most of the time and had my SmartWatch 2 connected via Bluetooth since I unplugged from charger. Heavy usage while coming home from work (Facebook, Twitter, music) throughout. I've never used STAMINA mode before, dont really see a need to!
[Xperia Z2 General] chesterr:
Another review says that it didn't match S5 and M8's battery.

How about the SOT?
[Xperia Z2 General] cr0wnest:
Ah I forgot to screenshot that one.. But if I remembered it was around 4 hours SOT and CPU awake time was 5 hours plus or so.

I don't know how it fares against the competition, but the Z2 battery life is pretty damn good for my usage.
[Xperia Z2 General] vlawrence0324:
Good SOT considering the CPU awake time is 5 hrs+. What more if the stamina mode is enabled. CPU wake time is reduced thus improving battery. I believe that if you can get through a day with your typical usage (without limiting your usage) it should be perfect for you.
[Xperia Z2 General] cr0wnest:
Yeah its MORE than enough for a typical usage in one full day, and I usually left at least 40% by the end of it which is very impressive considering this is without STAMINA or any other built-in power saving feature enabled.

I've also heard the M8 fares better, if this is already amazing I cant imagine how that one will be like. :laugh:
[Xperia Z2 General] chesterr:
You think you can test more and next time will you take a screen shot of SOT too.

Thanks :)

Cause there's no way of M8 fares better, and S5 beats M8 so Z2 gotta beat everything. And yea who knows what's the stats will be with Stamina ON. :)
[Xperia Z2 General] cr0wnest:
Sure I can do that. I'll test it on days I go to work. Because that's when I use it the most. :)
[Xperia Z2 General] Jiyeon90:
Android authority said the the battery is on pair with the S5

[Xperia Z2 General] TheOnlyIntruder:
I think I know what test I'm going to do when I get my Z2.

I often like to watch anime on my OneX and the anime I watch is often encoded in 720p h.264 hi10p (so this has to be decoded in software - very cpu intensive) and when I've watched about between 90-180 minutes, from 100% charge on my OneX I'll be left with about 30% battery (sometimes less, sometimes more by ~10%) so when I'll get my Z2, I'll see how this compares ;)
[Xperia Z2 General] cr0wnest:
Today's usage. Much lesser SOT and CPU usage, but yet the battery drained a lot more, not sure why though. But I did use the camera for quite a bit in the evening to take shots in relatively dim lighting. Also uploaded pictures to Twitter, Facebook well as Instagram over LTE. I was using the Smartwatch 2 via BT in the evening when I went out to dinner.
[Xperia Z2 General] chesterr:
According to Basel from Btekt he claims it lasts for two days when the others died out within the day.

So everyone's getting mixed feelings about it. LOL

http://www.engadget.com/2014/04/18/sony-xperia-z2-review/

xperia z2 whoops tops the competition in the engadget battery test - though they did say that the test slightly exaggerated its real world longevity.

Xperia Z2: 13.5 hours, M8: 11.5 hours, S5: 10 hours.
[Xperia Z2 General] iDroid8:
Regarding the Engadget review, it was riddled with inconsistencies, mistakes and numerous things not being covered. Awful review.
[Xperia Z2 General] chinedu40:
Completely agree. Especially how they slate the phone for having a quick setting system which they say takes longer than the M8 or nexus phones, when it works in exactly the same way!

I'm personally waiting for The Verge review and hopefully (although unlikely) and anandtech review
[Xperia Z2 General] Siema89:
I've attached my battery experience. Must say, I'm impressed.

Brightness on auto. Generic use (some games, internet, music, camera etc. Was checking out apps :P) Wi-Fi/3G all time on (disabled turning it off in stamina settings, left only the downclock part)
[Xperia Z2 General] Seifer1975:
This is my battery usage. Not as fantastic as some people here but I want to highlight that these are achieved on

1. NO stamina mode AT ALL.

2. Using LTE throughout. No WIFI

3. Auto brightness but bar set to brightest throughout

4. Bluetooth on for about 10 hours and connected to both Sony smart watch and headset

5. Location services on throughout

I am very satisfied with the battery!
[Xperia Z2 General] vlawrence0324:
This is absolutely brilliant battery test. Thanks

[Xperia Z2 General] stargate1000:
This is mine after the very first initial charge.

I'm hoping it gets better with a few charges under its belt but I'm still well happy.

I'm on the thing all the time throughout the day and I'm getting good screen time which I'm well happy with.

Love it.
[Xperia Z2 General] edge3uk:
Lol 5hrs SOT and you still had 23% left. Nearly quarter of the battery. :cool: no stamina mode too??
[Xperia Z2 General] cedropol:
How about brightness? And w/wo auto?
[Xperia Z2 General] TheOnlyIntruder:
Yep, I can confirm this, I've used my Z2 in exactly the same manner as my One X. I've made several phones calls, sent several text messages, watched a total of between 4-5 hours h.264 hi10p video, listened to music for a total of 2 hours with the active noise cancelling earphones and another 2 hours bluetooth streamed audio to my car stereo, after all that I'm currently at 27% remaining battery with 6 hours of screen on time and I took my phone off charge at 9am yesterday.

I'll post a screenshot later on today to show this either at 9pm or when my phone gets to between 5-1% of remaining battery.

Definitely impressed so far I must admit, with this same usage my One X would have had two charge cycles (2-3 hours of the same video content would drain roughly 70% of it's battery).
[Xperia Z2 General] TheOnlyIntruder:
Right then, as I stated in my previous post, I'd upload screenshots of my phone's battery performance and I am utterly impressed. It's about time we had a phone that can do all of it's capabilities without needing to be charged just a couple of hours after using it.

I made use of the Stamina mode and Low Battery mode as these modes fit quite well with my usage and I would say I've used the phone typically more than I would ordinarily but not in the sense of testing features and such, I haven't done anything I wouldn't have done on my One X, so for example this evening I spent more time listening to music and also read some manga on the phone I must say that this screen is great for reading manga too, perfect size.

Now I'm just curious how long it'll take to fully charge.

Edit: Just wanted to add

Looks like I have comparable results here
[Xperia Z2 General] vlawrence0324:
Does Lux help with SOT?
[Xperia Z2 General] stargate1000:
I would imagine it does a little. I use it on its dynamic setting its way better than Sony's effort I reckon. I also set it to plus 10 or 20 as an additional level of brightness to its standard state.

I have been using lux since my Htc One. It just always seemed better than the stock brightness option.

---------- Post added at 09:31 PM ---------- Previous post was at 09:30 PM ----------

Yep no stamina mode. I haven't felt the need to use it yet!!! :D

[Xperia Z2 General] stanley08:
No radio signal? offline?
[Xperia Z2 General] vlawrence0324:
I was also wondering if you have the mobile data on the whole time. I want to see how this phone can last when on 3g/4g all the time without the stamina mode.
[Xperia Z2 General] TheOnlyIntruder:
Didn't have data turned on at the time of the screenshot, my habits are that I turn data off if I'm at my computer and turn it on when I'm out. It's a habit I picked up when I had my HTC Desire since that thing would run flat so quick if I left data on all the time.
[Xperia Z2 General] daven:
Does anyone mind sharing what sort of use details their getting with Android OS - I think something isn't quite right, I'm getting Android OS keep awake for 8 hrs so far off a 1 day 6hr on battery with 25% remaining and 3 hrs 40mins screen time , which is still pretty decent but it's nowhere near the 2days w/8hr screen time others are getting.

It doesn't seem normal for Android OS to be keeping the device awake for 8hrs?
[Xperia Z2 General] Rajaasim1980:
I wish this phone give 7 hour screen on time at least because my last phones lg g2 and moto g did that and i dont think i will go for any less
[Xperia Z2 General] Seifer1975:
After about 6 hours of usage, android os was 8%, keep phone awake for 36min. Then again your stats look quite normal to me. That last 25% should about make your SOT 5 hours thereabouts. I am roughly getting the same utilization stats.
[Xperia Z2 General] daven:
Thanks for the reply! I think the phone is being a bit weird when it comes to being on standby, like if I use the phone over the day I'll get 5 odd hours SOT with 1 day 10 hrs usage but if I don't use the phone I'll still only get 1 day 10 hours useage but just with say 1 hour SOT but my android OS percentage will be higher than my screen time percentage - I seem to be having the same issue on my z ultra, I didn't use it for a day and my android os keep awake time was 19 odd hours :/ I'm not really sure how much keep awake time is normal while the screen is off

Just out of curiosity how much of those 6 hours was SOT?
[Xperia Z2 General] ImS0Raw:
You all make me so excited of this phone. My first android phone was the good old Sony XPERIA x10i. I loved this first phone. It still works fine! After four years. After that phone I bought a Samsung Galaxy S3. I really loved the screen, it was a great improvement, I loved the speed of this phone. But it's such a bad quality phone (for the fanboys, in my opinion!!) ... I got so disappointed. Now my next phone is going to be the XPERIA Z2. And when I read how good the battery life is it makes me so excited. The battery life on my XPERIA x10 was better than my Galaxy S3. I should get the phone in 1-2 weeks. Such a pity Sony takes such a long time to release the phone... But it's worth the waiting.
[Xperia Z2 General] stanley08:
Same thing I'm thinking, I'm on Note 3 with stock 3200mAh battery which gives me 9hrs Screen On Time (8 hours minimum). I'm not ready to settle for less either but 7 hours would be decent and it's Snapdragon (compared to my Exynos Note 3) so I should be able to run AOSP roms on it. So, yh. :)
[Xperia Z2 General] Rajaasim1980:
9/8 hours is very good..do you get this SOT on WiFi or mobile data? Yea i consider myself heavy user so battery is very important for me..samsung is best in this department as they are still using removable battery which can be replaced and you can also carry extra with you on long journey/trip
[Xperia Z2 General] daven:
Figured out what the problem is, seems I have a rogue app stopping the device going into a proper sleep when the screen is off by keeping the wifi active - seems to be a similar problem with the nexus 4 after the kitkat update (probably unrelated given I seem to be the only one affected by this?). With wifi off I've had the phone on for about 4 hours now with less than 3-4mins keep awake which seems more reasonable, and battery has dropped from 100% down to 98% in that time
[Xperia Z2 General] stanley08:
WiFi only. I bought a pocket router so i use WiFi even when i'm outdoors. Lol. :)

Hi guys

Here some quick summary about my phone:

Got it yesterday, charged until 99% around 5pm and reached about 27 hours later 17%.

Screen on time was 6h 4min, Wi-Fi on for 22h 46min (I was mainly at home, Wi-Fi turned off when no known Wi-Fi network in reach[location-based Wi-Fi on]), LTE (mobile data) was on the whole time, but since I was in a Wi-Fi network it did not take much battery.

Played about 10 minutes a 3d game ("smash hit"), 1h 50 min music ("shuttle", about 1hour with screen off), surfed approximately 2 hours reddit (youtube videos, pictures, normal threads, somehow “reddit is fun” shows only 32min, time could be 2,5 or 3 hours…), the rest was testing and settings and playing around.

Low-battery-mode is set to under 15%, so it did play no role here, stamina mode off, queuq background data on.

I attached the screenshots, but they’re in German, maybe still useful. If you have any questions, just ask.
[Xperia Z2 General] kartoonz:
I dont understand why all of you guys are posting battery stats with wifi turned on for 20hrs and more... Damn it, it's a freaking mobile device so post results with lte or 3G network and not wifi...
[Xperia Z2 General] SkyS1gn:
Every feedback is a feedback, this way, we get a broader picture of what this beauty capable of.
[Xperia Z2 General] stanley08:
So I have a pocket Router which is always in my pocket or backpack when i'm on the move. I'm always on WiFi, I don't have a 3G plan active. So wats the problem?

Excellently said! :)
[Xperia Z2 General] edge3uk:
Okay I'll be totally unprofessional and submit my dodgy graphs of doom. I've absolutely hammered this thing today. Camera, games, uploading, downloading, making videos, a 4k video of it getting attacked by a tap.... Pretty much anything it could be asked to do. Also an hour phone call to three for a replacement. It was charged to 100% on the dock last night and it's been docked a few times today. It's just be assaulted in the pub by everyone who's stunned by the looks...

wow thats smart indeed... a wifi device in your pocket... i guess what you are assuming is that 99% people do that, is it!! i'm not trying to act smart here but all i'm asking is users to post results with LTE/wifi on... so if you cant contribute to my question, stay out mate...
[Xperia Z2 General] SkyS1gn:
SOT not really relevant if you charged it throughout the day.. i would say without that charge, it would still perform a solid 5-6 hours of SOT.

I ask because on my Z2 on .55 I see different ON/OFF toggles in UI.

[Xperia Z2 General] edge3uk:
My first full day. No stamina or battery saving modes used, in fact, it got to 1am and I had to put a film on to try and flatten it. Very impressive.

Also I noticed a setting in advanced wifi that scans for wifi points even when wifi is turned off. I disabled that half way through the day.
[Xperia Z2 General] JackHanAnLG:
Got it down too 3% And took another screen shot
[Xperia Z2 General] bombdog:
After a couple of cycles..

This is a fair example of usage in a bad signal area with wifi on constantly, Stamina mode on at about 30% and brightness set to about 60% - 70% most of the time. Was also showing off AR effects in the pub for most of the night (lots of people impressed by the gnomes on the pool table!). Have disabled/uninstalled a lot of bloat, but until it's rooted I can't find any potential wake locks, but all in all a massive improvement over my old HOX :laugh:
