I just can't believe the battery on this phone. I received the phone Friday afternoon. Charged it too 100% before I switched it on. Then carried on using it how I would normally. And since I haven't charged it until an hour ago. I'm now back to full battery. And been using my phone for five minutes and battery is now at 98%.
[Xperia Z2 General] edge3uk:
I've recently got the smartband and been playing around with settings. It seems that bluetooth and NFC on uses pretty much zero battery, as does the smartband. The only thing is goggles location services. If you have location on, the battery is gonna tank. I've set mine on battery saver today and I've gone from an overnight charge to 46% now, which I've never done on a smartphone. So check the location settings! Seems to be lumped in with android system.
[Xperia Z2 General] rkanwar:
When do you guys actually start charging your phone? Should I leave it and wait till it hits under 15% or if I put my phone on charge every night will that affect the battery?
[Xperia Z2 General] SexyIceCream:
1h 13 min of screen on time and batt is down to 80%...brightness on lowest setting.

Seems that Google play services is taking a huge chunk of the batt. what is this and how do i kill it?

More than happy with my battery life!!

Mobile internet on all the time WiFi on all the time auto sync off screen on full brightness with adjust bit on and no power saving

Just general use of surfing email phone calls and text and a few day to day apps banking etc

I used it the same way I used to use my One X which I have just come from with the exception of mobile internet always on and WiFi always on

3 days old Z2, after 89% charge. Wi-Fi , bluetooth and 100% screen brightness with smartband connected all the time.

[Xperia Z2 General] edge3uk:
I'm not getting anywhere near that with my smartband. Have you disabled all location tracking?
[Xperia Z2 General] KyleSforza:
nope, that's at high. But I don't leave NFC on.

P.S. That's with Stamina mode on.
[Xperia Z2 General] CandyAndy:
How is it possible that no more comments about the battery life of this phone. It is one of the most important things I am looking in a phone. I sometimes have very long work days and phone can't fail me during that time. First talks are that M8 would have better battery life. If this is true I think that I might go for HTC (also) this year.

Camera seems to be good enough or bad enough on both of these devices so it isn't the dealbreaker here.

Also slightly worried of the durability. My M7 has dropped several times and only minor scratches. I think that Sony would be shattered already.
[Xperia Z2 General] Shudder123:
it's barely even released. i don't think people can comment on the battery life if they don't have the device..
[Xperia Z2 General] CandyAndy:
To my understanding its already released in Taiwan and probably also in Singapore?
[Xperia Z2 General] augie7107:
Well stated, plus you could take 1000 people and they would all get different battery stats based on how they use the device, apps installed/running, services utilized, strength of signal etc.
[Xperia Z2 General] Shudder123:
Yes, while that may be true, most of the people that own/will own the device don't flock on xda comparing battery stats and photos.

just checking around various ebay stores, some are taking in pre-orders still and won't be shipping them out till the end of the month. so we may have a wait a while before steady battery stats start coming in.
[Xperia Z2 General] KyleSforza:
Its battery life will definitely be better than that on the M8. ;) Good battery life has never been HTC's forte.
[Xperia Z2 General] Shambola:
Perfect scenario to make statistics ...
[Xperia Z2 General] KevinB88:
But everyone will learn any day what you could do better. And maybe htc has learned how to make Battery life better and longing later than anything before.

I got the m8 , and I'm gunna pick up the z2 as well to compare. M8s battery is amazing, 7.5 hours screen on, 13 hours total, with 10 percent left. Didn't screen shot these stats sadly.. I hope the z2 is better but if not then the m8 will be the keeper.
[Xperia Z2 General] KyleSforza:
That's logically impossible you know.

M8 has 2600mAh , Z2 has 3200 mAh. Same internals and everything, the display on Z2 is LTPS IPS which results in lower power consumption.

3200 mAh > 2600 mAh is a huge difference. 600 mAh is a lot.
[Xperia Z2 General] KevinB88:
But it's a matter of efficiency too. If everything but battery is the same, the OS can make the advantage of battery useless. But I hope battery life is better than on Galxy S3.

Gesendet von meinem GT-I9305 mit Tapatalk
[Xperia Z2 General] KyleSforza:
Both make use of Android 4.4.2. Sony has less bloat, and that Stamina mode is just amazing. ^_^

Anyway, 600 mAh is way too much to let OEM customizations have any effect on the battery life.
[Xperia Z2 General] Xernoxis:
And then you just take the average from those 1000 and you got a good pointer.
[Xperia Z2 General] augie7107:
Exactly, when/if you get 1000. Five isn't going to do it.
[Xperia Z2 General] g4rvd4:
Yes, but the initial battery reports that are coming in don't talk about the Sony's battery that highly. Frankly I hope they're wrong about it, seeing as how logically it should be the way you describe. But if it turns out that the Z2's battery is not up to the mark, I might have to go over to the M8 camp. They've been getting excellent battery performance over there.

You mean 4.4.2.
[Xperia Z2 General] KyleSforza:
Thanks for the correction.

To be honest yup M8 has marked a great improvement in battery tests so far, but we haven't even seen Z2 and S5's battery tests yet. I'm expecting Z2 to score higher than M8 in GSMArena review, as I find their endurance ratings to be the most reliable.
[Xperia Z2 General] MasK:
I came across this article:

http://wiki.mobileread.com/wiki/LCD

Now looking at how bad the Z1 does with TFT, I'm starting to worry.

Now I'm now sure how good this LTPS is though..
[Xperia Z2 General] KyleSforza:
You're aware M8 also has a LCD right? Which they call "Super LCD". lol

LTPS is very power efficient, remember the rumors of IGZO in the Z2? Guess what, they switched that with LTPS. Just like Apple did. Apparently LTPS is more energy efficient and better than even IGZO. LTPS is the tech used in the display of Nexus 7 2013 aswell.
[Xperia Z2 General] Haldi4803:
But you DO KNOW why the m8 beats all other phones, even the LG g2 in Web Browsing Battery tests ?

For web browsing this self refreshing of the Panel is the Battery saviour god ! We saw that in the LG g2 how awesome that worked! HTC now made their own implementation of that!

If Sony's Z2 does NOT have this technology you will get better results in Video duration Benchmarks, but all Browser enduration benchmarks will be worse than the M8 ! just slightly better than the Z1 ! :cowboy:

Same goes for writing SMS and all that daily stuff!

i really hope they have something similar built in... would make me Buy the Z2... but i'm very sceptical !
[Xperia Z2 General] g4rvd4:
The HTC One M8 is looking like the better package overall.. :-/
[Xperia Z2 General] kngyr:
Hey guys, I know this has been probably been spoken of a bit, but can anyone help me figure out why yi have such high Android OS usage, I still get awesome battery life 1d+, 4h+ SOT. Surely I can squeeze a little more out.

Yes, as your not using your phone enough Android os is your biggest drain, use the phone more and screen etc will surpass it.

[Xperia Z2 General] JackHanAnLG:
Same here !
[Xperia Z2 General] kngyr:
That's what I've been thinking. Although the screenshot I posted had 3.5hrs of SOT, which is quite a lot?

I'll try again see how that goes.
[Xperia Z2 General] TheOnlyIntruder:
If he's not using his phone a lot he should be getting two days out of his phone, I did but then again I have been using stamina mode anyway which blocks programs from accessing data while the phone is in sleep otherwise there might be an application that's causing the phone to stay awake hence why Android OS is using a lot. Have you got push notifications enabled for anything? Is it necessary? Perhaps you only need hourly updates etc
[Xperia Z2 General] vlawrence0324:
My 2nd full charge. Very impressed with the battery life. I nearly have 5 hrs of screen time and still have 40% left. High accuracy location, Google now off, stamina mode on, pretty bad signal, Wifi only. Dropbox uploaded almost 200+MB of video for almost an hour. Watched some movies, texting, messaging fb news etc. Some great juice inside this device.

Battery performance is very good!

Good job Sony!
[Xperia Z2 General] metcard:
Andoid OS should never be that high.

If he isn't using his phone that much phone idle should be highest, even Android system should be higher.

Check how many hours Android OS has kept the phone awake for and if the awake hours are high and you didn't do anything with the phone whilst the screen was off then you have an app or service bugging out.

I had this issue with the xperia Z after an upgrade and rebooting would fix it temporarily, but eventually I got sick of it and done a factory data reset which fixed the issue permanently.
[Xperia Z2 General] ProdigalFather:
I seem to be having an issue over the last few days - horrendous battery life..

Android OS usage seems high. SOT is currently 1h 56m Can anyone think of any idea why? Should I get the phone exchanged?

Stamina mode is on with restrict performance and queue background data on. Autosync is on. 4G is off so just 3G and WiFi throughout the day. Brightness at lowest setting with adapt ticked. I just don't get it :( the phone seems to keep waking up a lot so maybe that's the issue?

I turn that and Bluetooth icon off in personalization menu, as well as the battery percentage since I no longer have to worry about it with this device. :p

I turned on the bluetooth and percentage icons just to share the stats. xD
[Xperia Z2 General] kngyr:
Yesterday Android OS held it awake for just over 4hrs or so. Perhaps it could he a service bugging out, as I don't have many apps installed. The apps that require notifications or location services are updated hourly. But since its early days, I might do a factory reset.
[Xperia Z2 General] Haldi4803:
but you do recognize that Picture the Android System has, do you ?

In case you don't, it's written under the "included Packages" section, the one at top uses the most Battery !
[Xperia Z2 General] BanziBaby:
Hmm never noticed that mate, I have never used the throw functionality at all, the thing that was bothering me other than the high android system usage was the gps being active for 5-6 hours, I usually have that disabled.
[Xperia Z2 General] Pesetio:
Very good battery life

Could of got more if I disabled smart backlight, this seems to be quite a battery drain for me.

I have double tap to wake on but I didn't notice any difference in battery drain.

Mostly watched youtube, took a couple of short phone calls, played with the camera for about 5mins, some browsing in chrome and a little bit of gaming.

Could of got a bit more battery life if I used Interactive govenor, I used conservative just to try out.

Bluetooth, GPS, Auto sync were all off and I set low power mode to kick in at 10% but still have wifi.

it seems that I usaully get 8 hs sot,which is not bad.with everything tuned,it becomes 10hs
[Xperia Z2 General] Kamran9558:
Best smartphone iv ever owned in terms of battery life. I always used to start getting worried about the battery around 7 o clock with every other phone and coming from a nexus 5 i am much much happy. NExus 5 was slick and smooth but battery life and camera not so much.
[Xperia Z2 General] vlawrence0324:
How do you know if smart backlight drains the battery? I'm thinking if disabling this since it doesn't work all the time. Or maybe I'm always in my room which is pretty dark and the phone is having hard time detecting my face. Though I believe that the double tap to wake is convenient since I don't have to reach the power button on the side when I'm reading something and the screen went off.
[Xperia Z2 General] Pesetio:
I just looked at the percentage while I kept moving my phone and noticed that it drops faster then normal. I think it uses the accelerometer or something, it doesn't check to see if your looking at the screen, it seems to just check if your phone is moving or not.

You can test it out by setting timeout to 15secs, turn your phone upside down and keep moving it, as long as you keep moving it the screen won't turn off.

The tooltip is very misleading.
[Xperia Z2 General] vlawrence0324:
Thanks for the info. Your are right. I just tried it, I kept moving the phone without looking at it and the smart backlight works. On my experience it also works when my face is detected in good lighting condition.
[Xperia Z2 General] Pesetio:
Was the phone in your hand or was it on a flat surface?

If it was in your hand, then maybe you moved it slightly and didn't notice. If it was on a flat surface then maybe it uses the camera as well.
[Xperia Z2 General] vlawrence0324:
Edit: it was in my hand.

I'll test it while docked.

Update: nope, smart backlight not working when looking at it while on a flat surface or docked. So it seems that the sensor is using the accelerometer or gyro for smart backlight not the camera. info tooltip is very misleading indeed
[Xperia Z2 General] Pesetio:
Thanks for testing, that's what I figured, since it would be weird that they would use 2 different sensors for it.
[Xperia Z2 General] -nlf-:
excellent:good:
[Xperia Z2 General] Devzz:
I have just charged my phone overnight to 100% and have stamina mode/low battery mode on, tap to wake disabled and auto screen brightness on. No location services or GPS or anything like that yet my estimated standby time is only 1 day 13 hours! Do I need to factory reset my phone or could it be something else? I had to get the phone swapped for another Z2 because the first had a dodgy headphone jack so I've only had it around 2 days now. Before swapping to this phone, my other Z2 got an estimated 6.5 days of standby!

On another note, unrelated to battery but does anyone here know why my phone won't auto install my apps once I've signed in and set the phone up initially? My nexus 4 would reinstall all my apps automatically after a clean ROM flash but the Z2 doesn't and I have to install everything manually again!
[Xperia Z2 General] kartoonz:
yep can you just do a factory reset first... that should fix the issue:good:
[Xperia Z2 General] Devzz:
3rd factory reset in a week between 2 different devices! :eek: FML. I'll update in a short while, thanks for replying! :) What do I do in case of it not working properly?
[Xperia Z2 General] vlawrence0324:
If you are just new to the phone the google won't restore all your apps. Install all of them manually the If you have backup enabled and you do a factory reset on Z2, that's the time Google will restore the apps. For you convenience just go to play store > my apps > all. Then hold down the app name and select which one you like to install. This is easier than installing one by one.
[Xperia Z2 General] kartoonz:
but i guess this is the first time you are performing a rest on this device?? in either case you can then hook it up with the sony pc companion to repair the phone..
[Xperia Z2 General] Devzz:
I fixed the back up thing by going to backup and reset and unticking/ticking the Automatic restore option :) As for the battery estimated standby time thing, it worked! Thanks for your help :highfive: :good:
[Xperia Z2 General] exdas:
So what are the values now? Can you show a screenshot?
[Xperia Z2 General] kartoonz:
glad it worked...:p pls share your battery stats once you have the time
[Xperia Z2 General] Devzz:
Hey guys, sorry didn't reply earlier! I didn't take any screen shots but at the moment my battery chart is pretty erratic. There's a thin line cutting through the chart vertically and I have only got 2.5 hour screen time. On the previous Z2 I did get 6.5 days standby estimate and at one point I got 17 hours with 6 hours 30 minutes SOT. I'll post an update tomorrow morning with screenshots once I've done a full drain/charge cycle tonight! :)
[Xperia Z2 General] Don MC:
No need to reset phone. Just clear data of Eco mode controller in the apps section, reboot and set up Stamina again. That should fix the estimated battery time in Stamina.
[Xperia Z2 General] insom:
How do you do that?

Edit:I figured out thanks.
[Xperia Z2 General] Devzz:
Ah man, thanks for the reply but unfortunately I already reset it not too long after posting! I've just done it again to make sure. I'm going to let the battery drain to 0 and then do a full charge to 100 then post results with stamina and low battery mode on :)
[Xperia Z2 General] lovemyram4x4:
Battery life isn't as good as expected but has been adequate.

Aside from using Lux and turning off data traffic while on wifi(yet I still see H, H+, E & 4G at times) I'm not doing anything to prolong battery life. I have SIP(VOIP) on for incoming calls while on wifi, all locations services on, BT(with SW2 connected 24hr/day) and NFC always on. I've been getting a full day 15+hr with 4hr SOT.

Z2 has best battery of all android phones, so saying battery life isnt as expected is kinda stupid:D

I find lux, to be more of battery drain with constant wake locks, in fact the most when I had it installed.
[Xperia Z2 General] fakelouis_:
For those who have 7+ SOT, I'm wondering are you guys always on wifi while browsing, or did you guys browse with 3G/LTE? I've only got 4+ SOT with wifi and 3G browsing..
[Xperia Z2 General] feis:
On wi-fi i can stretch as far as 10hours sot. On 3g i usually get upto 7hours, if playing games, then a bit less. Very very satisfied with battery, best ive ever had
[Xperia Z2 General] fakelouis_:
7 hours?! I've only manage to get like 5 hours..
[Xperia Z2 General] ikhsaricky:
I get almost 12-14 hours
[Xperia Z2 General] feis:
Keep in mind i have autosync turned off, i do it manually when needed, background data queue is on, stamina on, restricted performance on(dont feel any lag anytime), and autobrightness on.
[Xperia Z2 General] fakelouis_:
I had auto-sync, GPS, bluetooth, NFC all off. No stamina mode, only badkground data queue. Only 3G on, and use wifi is possible. Auto brightness on at middle level. Hmm I wonder why... now I'm down to 60+ with 2 hours SOT
[Xperia Z2 General] feis:
Maybe you live in rural area with weak signal? It can be a huge factor, another possibility is rogue app not letting device sleep properly
[Xperia Z2 General] fakelouis_:
Oh yeah, possible. Although I'm living in the capital of the country
[Xperia Z2 General] Don MC:
...which doesn't mean the signal has to be strong. Actually, it can be much weaker in the city, due to all high-rise buildings and other cellular traffic going on.
[Xperia Z2 General] vlawrence0324:
Plus congestion due to lots of people sharing in same cell tower.
[Xperia Z2 General] fakelouis_:
Nope, in my place the signal suppose to be good, plus I'm on a better telco. Oh wells :cyclops:
[Xperia Z2 General] lovemyram4x4:
I find that odd, especially since I've always had Lux setup in the way that the app would be the most active(when awake), but I've never had issues with it not going to sleep when the screen is off(I did at times have problems Lux not waking with screen at time with my old phone) and most of the time Lux is making the screen dimmer than the built in auto brightness.

I'd still use Lux even if it does drain my battery more than not using it just because most of the time the screen is a lot brighter than it needs to be in lower light(indoors) yet doesn't go to full brightness quick enough when it's bright(outdoors). Plus I wouldn't want go without profiles and Tasker plugin.

Which reminds me, I also have Tasker running which can wake device often or even keep it awake depending on how you have things set.

Anyway my device does go to sleep but wakes for short periods of time for things like syncing(I have some things set to sycn fairly often instead of turned or off) but spends most of the time when the screen is off sleeping, screen has been biggest battery drain.

Also forgot to mention cell is usually a big drain on my batteries, living in SoCal coverage is spotty with all the hills and really bad at my house.

It is nice that I can get a lot of SOT and still get a full day while using my SW2, I couldn't get a full day at home(when driving car dock charges) with much less SOT using the SW2 on my old phone(Razr HD) and the Z2 probably does better with the SW2 than the Razr HD did without(plus I also did a few things to try and save battery on it).

[MENTION=2885927]LiveSquare[/MENTION] I follow you since the Xperia Z fórum and you've helped me a lot, because of this I have two questions (hahahaha):

1) Has anyone noticed improvement in battery performance on .402 firmware?

2) Double Top to Wake consumes more power than normal?
[Xperia Z2 General] Fadeless:
Is it bad to be on your phone while its charging? I am scared of using my phone while its charging in case it ruins the battery, I heard this somewhere before but not too sure if its true.
[Xperia Z2 General] Don MC:
Try it without. Keeping the digitizer on at all times HAS to have some effect on the battery.
[Xperia Z2 General] BR4DOKYBrazil:
Do you recommend me to do full wipe or just wipe cache and log??
[Xperia Z2 General] BR4DOKYBrazil:
Yes, via Flashtool! After I updated my device to .402, he is sucking the battery more than normal! In battery management the "screen" appears with 71% of consumption! Or is it because I did not do full wipe or is the double tap to wake it activated shortly after I did the update and not deactivated more!
[Xperia Z2 General] Pesetio:
Would of got more standby time had I known my brother set the timeout to 30mins and less SOT. Notice the phone idle, it was just wasting screen time doing nothing. I used YT for close to 3 hours, so phone idle would of have been a little bit over 3 hours.
