IIRC. ... Google.gms comes from the play services. Deactivate auto Sync, backup and mobile data to get rid of those!

Android system comes from mobile connection, switch to flight mode!

Fast dormancy, aka android.sony.wakeup is caused when the phone tells the provider, don't switch off my fast mobile data, I still need that. 12 wakelocks for 2 seems like it's working fine. If it's bugged you have between 500 and 1000 wakelocks in a hour.

Your alarm page looks completely fine! Just Try one day without bluetooth!

yeah, could You please continue to play 2048 for the next 20 hours so we can be sure thats not fake? ^^
[Xperia Z2 General] alberber:
You think it's a fake or what? Obviously, battery is not going to last 20 hours but that 5% is amazing. I'll post final results at the end of the cycle, but right now I'm still on 47% with 5 hours of SOT.
[Xperia Z2 General] edge3uk:
I have noticed playing 2048 make my Z2 cool down somewhat. It uses like no battery lol.
[Xperia Z2 General] Haldi4803:
"^^" imply that i was obviously grinning hard while writing this.. thus it was irony.

I'm not saying it's fake but it's normal for phones to take way longer from 100% to 95 or 90% than from 20% to 15% or 10% Thats how batterys work. you can't calibrate them perfectly.
[Xperia Z2 General] stu_tls:
Are you sure? Mine have always been the opposite

The first 5 to 10% just flies down but the rest takes ages!

~.~ Using Exchange active Sync and 2 Accounts in Push causes bam_dmux_wakelock -.- don't excluded email from Stamina mode, you only get emails when screen is on. but it saves battey! by a lot.
[Xperia Z2 General] Chad_Petree:
HTC almost made the best android ever, they just effed up for me with the camera, and that's enough of a deal breaker , but for people who don't care about their camera is the perfect phone! :cowboy:
[Xperia Z2 General] chesterr:
We don't know about that yet, nobody has really said anything about the battery properly. and GSMAreana didn't get the phone as well.

and it all depends on how the user uses the phone too. you can't really depend on how the reviews and what they say about it.
[Xperia Z2 General] illphone:
What makes you think that?

I want to know because I'm torn between these two phones, they are so similar technically (besides camera) that small things make the difference.
[Xperia Z2 General] CandyAndy:
I was 100% sure that I will go for z2 but the last two days I have had second thoughts. If Sony would have released the phone by now I guess that I would be a happy z2 owner but it could be that on Monday I am (hopefully) happy m8 owner.

Camera really isn't THAT bad on m8 and it's not THAT good on z2 on the other hand.

Battery life is the most important thing for me.
[Xperia Z2 General] illphone:
Ok, got your point. So we are basically in the same boat, I would also prefer more battery life over the "better" camera.

I think I will wait for a few more reports (that is the plan) or I will just buy the HTC next week (not planned but most likely) :laugh::D
[Xperia Z2 General] plonkersaurus:
It depends if you want the

bigger screen (which is arguably also higher quality based on some comparisons)

waterproofing

noise cancelling earphones (I have ones but with a separate box with AAA battery and to get rid of that separate box would be great, I think its also going to have much better cancellation as mine are analogue)

120fps video recording

Tap to wake (really looking forward to this) - edit (m8 has this too)

Stylus mode using pen/pencil (looking forward to this if its like the Z Ultra!)

Smart brightness that stops the screen turning off

Dedicated camera button!

1gb more RAM

4K video if you care (I don't)

Better notification light

Extra sensors (Barometer sensor, Game rotation vector, Geomagnetic rotation vector, Step counter, Step detector, Significant motion detector)

According to the whitepapers, the Z1 has 6.66 video playback time (gsmarena says 5:59 web browsing, 6:12 video, the Z1 Compact has 12 hours (gsmarena says 12:37 web browsing, 10:01 video), the Z2 has 10 hours video playback time. No benchmarks for Z2 battery yet, but seeing as the whitepapers from Sony are surprisingly accurate for the Z1 and Z1 Compact, I think we can be hopeful that the battery life will be around 10 hours.

One further thing is, I think Sony are doing better software updates than any other manufacturer at the moment. Rather than just updating the android version, they are updating the full system to run their latest software. I've been using the Xperia Z for a year and have been really happy with the updates. Yes it takes them longer to update to an android version, but when they do, the whole UI is revamped to look like the latest in the Z line, I'd hate to be stuck on the software the phone launched with (it looks much better now). In truth, I'm only upgrading because my sister broke her phone and she wants mine, otherwise I'd be perfectly happy with the Z and it's massively inferior to the Z2!
[Xperia Z2 General] Haldi4803:
And Sony has the best dev. Community xD

BTW, this 10h video Playback from the White paper is the ONLY known fact (useful rumour) about Z2 Battery life, isn't it?
[Xperia Z2 General] solwretep:
It could be interesting to see screen on time while browsing etc at lowest brightness. It should be really good

[Xperia Z2 General] MSIOCGenie:
Same internals? Are you kidding me? Do you know for a fact that the Z2 also uses Qualcomm RF360 parts such as the envelop tracker and radio matching tuner?

Besides, the G2 and Z1 had the same SoC and battery size, yet G2 had significantly better battery life, and a larger screen.

Also HTC is really serious about Sense and updating their phones nowadays.

I'm having this problem with lifelog

My battery is always a day, sometimes less, I dont have a ton of apps, just a few games and whatnot. My smartband could be the issue tho.
[Xperia Z2 General] Haldi4803:
I think I somehow bugged my phone.

The first part was normal and standby. Then when it starts falling I played Symphony game for about 30 minutes.

Pressed close all in recents.

Used the phone as media playee for 2-4hours.

And then... Nothing! The phone just continued to drain battery like that. Even tough I did nothing! BBS did not show wakelocks. But I had roughly 3% per hour.

I mean just being in a 4G network can't just drain the battery if the phone is idle...

I assume symphony app did NOT correctly close and kept running in the background.
[Xperia Z2 General] ajai_dev:
I have installed FPse and game "Tekken3" once in a while in all the battery never lasts more than a day of general use including wifi and light gaming "Tekken3 and GTA"

This is all very subjective and I cant be bothered with screenshots etc..... but

WOW! I love this phones battery. I'm probably an medium-heavy user, lots of texts a couple of hours of gaming, facebooks, streaming from play music a couple of hours etc etc + have the SWR10 wristband + lifelog running so NFC and bluetooth in constant usage .... yet still I have 45-50% battery left when I go to bed each evening!

Incredible!
[Xperia Z2 General] Haldi4803:
No way! There is just no way that works! That's omfgwtfhth?

What app did you use to watch the video? Not MxPlayer?

Local video on your sd card or streaming? h264 10bit video?

Screen Brightnes set to Minimum or automatic an it was extremely dark?

Guess you don't have better battery stats installed. Any other App like FauxClock or CPUspy that show which core was how long on which frequency?
[Xperia Z2 General] sfex3best:
Ok so I was using the stock movie player yes it only says 3 percent in my stats i don't know why because i probably spent like 7hours watching one piece with the movie app.

I have no idea what better battery stats does?

I have root and xposed modules installed with greenify on and i uninstalled almost every single sony app possible even stuff like maps etc.

I basically hibernated almost everything that eats my ram away yes that includes stuff like googlw services framework. Only left whatsapp unhibernated.

Stamina mode enabled also with extended battery usage ticked. I never used the below 20%low battery mode.

And basically only at around 50 I started staring my battery trying to get most out of it. So i actually think more screen on time is possible. I reckon at least 15 hours screen on time could be reached.

I think its mainly down to the movies app which hardly drains you battery at all. So if your sat at home watching a series all day with your movies app you'll get more screen on time than me.

Yes it was lowest brightness with adapt lighting ticked.

Just out of topic I see a lot of people with the Sony smartband. Are they even worth it?
[Xperia Z2 General] jacobjh26:
Photos leading to battery drain?

This might seem like a stupid question, but I'm currently on holidays and taking a lot of photos... It seems like I have less battery life than I usually would at home. Is taking photos a common battery drainer?
[Xperia Z2 General] belloni:
Hey, you don't have Google play services running I see, has this had any negative effect for you? Also no Sony enterprise or smart card service running, do you know what apps these exactly relate to?
[Xperia Z2 General] sfex3best:
No google play service has no issues if i open play store it will run correctly and Google play services will startup as it is only hibernated.

As for sony enterprise and smart card i really don't know what they do and i don't really need them I think it's for connecting smartwatches and smartbands.
[Xperia Z2 General] belloni:
I can't find Google play services in the greenify list, I have the donate version and every box checked in experimental features apart from telephony, where is it! Have system apps on also.. :s
[Xperia Z2 General] blackalice:
Haha, yes - taking photos drains battery big time.
[Xperia Z2 General] jacobjh26:

No one here seems to run apps like Skype. It would be interesting to know how the SOT gets affected when you have Skype running all the time. I get calls on Skype from home when am away so I need to have it on all the time. Skype is a POS app that wakes the phone often and ever since MS bought out Skype it has gotten worse. If the Z2 can manage 5+ SOT in 24+ hours even with Skype running non-stop in the background I would be impressed.

Good test, is it possible for you run the same test with Skype running non-stop in the background? Specifically version. 4.0.0.22082, only good version known to play nice with KitKat. All the newer versions are known to disconnect when the screen is off which renders the app completely useless and obviously can't receive calls plus msgs get delayed.

[Xperia Z2 General] Haldi4803:
not really happy with my last one either.

No really sure if it was because i was surving the Web/Tapatalk with bright Screen (outdoors) and listening to music with the speakers. Or if there was something else draining the battery.

Oh yeah, the awake time comes from Music listening.
[Xperia Z2 General] youtookmyname!:
I just got my z2 a few days ago and now have two or three full cycles on the battery. Love the phone, but the battery doesn't seem to be quite matching some of the performance I've seen in this thread, and I'm worried that there might be something wrong (my previous phone also had battery problems when I got it)

It could just be from me using sleepbot and play music overnight though. Stamina and low battery settings were on since 70 and 50 percent and my phone is on the latest non-modified firmware.

Do you guys think my battery is OK?
[Xperia Z2 General] belloni:
I wouldn't be dissapointed with that then, due to listening to music constantly in the background.

Too many factors when they report their stats. Don't take them too seriously as a must achieve number.

[Xperia Z2 General] antti91:
I am fairly satisfied with the batterylife of the Xperia Z2. But comparing with others here on the thread I feel like something is not quite right.

This is a typical days usage this far, only lunch time soon so it's pretty early. Took it off the charger before going to bed and lost 3 percent during 7 hours of sleep. Been using mostly Ebay app and Chrome and some social media apps. Stamina mode with all its options are ticked.

Extrapolating this scenario would give me little over 5 hours SOT over 1 day which is far from what others are getting. Btw, during work hours I use mobile data and rest of the day WiFi.

Phones:

Galaxy S I9000

Asus Padfone 2

Sony Xperia Z2

Have the GSAM app installed so you can post a break down of the app sucker page.

Go through the entire battery usage cycle to say about 5% so we can see how you are using the phone.

Not fake. The battery really is that good. I'm getting about 6.5hrs SOT from 100% to shut off, WITHOUT stamina mode and enabling full gps all the time.
[Xperia Z2 General] sofia-captivate:
But what do you use? Are you a heavy user?
[Xperia Z2 General] scoopdreams:
Pretty heavy user. Quite a bit of Web surfing, streaming video over network from my LAN storage, etc.

I suggest you bring your phone in to the service center and check it out if your battery life is still bad. I just hit 6:12 of SOT and enabled stamina mode to see how far it can push on the last 7%.
