I had this issue, with the phone not going to sleep. Now it works fine. It *appears* that the biggest culprits, at least for me, were location reporting / location history (thanks Google) and a rogue app (they need to be fed aka TNTBF). I actually got a pop up from Google / Android saying the app was likely spying on me!
[Xperia Z3 General] vittogn:
How did you solve it? Can you name the app? Tx.

[Xperia Z3 General] cowisland:
The app is called TNTBF. I uninstalled the app, turned off location reporting and history in settings. Yes, that solved my issue with the phone constantly using CPU with the screen off. Much better now. You can also use the stamina mode, it kills all background processes with screen off.
[Xperia Z3 General] Ultraman1966:
Something odd has been going on recently. Battery life has been halved but no obvious reasons.
[Xperia Z3 General] vittogn:
Wear vs no Wear

Take a look at the massive difference in deep sleep performance in the very same conditions.

Am I the only one with this type of behavior? I have an LG G watch r.
[Xperia Z3 General] xxquicksh0txx:
It's keeping your device awake more often. Probably checking for notifications and stuff
[Xperia Z3 General] vittogn:
Is it normal in in your opinion/experience? Tx

[Xperia Z3 General] xxquicksh0txx:
I'd say it's normal to reduce battery life, but I can't say how much.

Since your phone is constantly talking to your watch(I assume)
[Xperia Z3 General] Bäcker:
it seems only via the magnetic connector if at all. Someone else reported USB charging is limited to 1,5A
[Xperia Z3 General] kerman19:
Battery life does indeed seem to be holding up well!

Screen on time was mostly comprised of text messages, with about an hour or so worth of phone calls.

[Xperia Z3 General] jonmorris:
I doubt it's via the magnetic connector. What I've seen elsewhere suggests Quick Charge 2 uses a higher voltage PSU (9V instead of 5V) and at 2A. Hence the need for the hardware to be designed for it.

Here's one: http://www.motorola.com/us/accessor...Turbo-Charger/motorola-turbo-charger-pdp.html

Presumably that's for the new Moto X, and so far I can't see anywhere selling a UK equivalent.

By the sounds of what I've read and what Qualcomm told me when I was at CES two years ago, the PSU will 'talk' to the phone to establish it can take the higher power to ensure the PSU can't damage ordinary phones (and so it will work as a standard charger for older devices).
[Xperia Z3 General] Blaalad12:
Battery life sure is awesome.I turned my phone on today for the first time at 4.00pm and the battery out of the box read 59% and now at 10.00pm theres still 26% left and thats with ALOT of usuage! Screen on time has been like 5 hours! I have however bluetooth turned off and mobile data plus brightness on auto
[Xperia Z3 General] Bäcker:
The Oppo 7, which uses quick charge, has a 4,5A @5V charger. This suggests that, if the Z3 is indeed quick charge compatible and the USB Port is limited to 1,5A this limitation could be bypassed using the magnetic port.
[Xperia Z3 General] jonmorris:
Where does it say the Z3 is limited to 1.5A?

It simply comes with a 1.5A PSU, but the Xperia S had a lesser PSU in the box and you simply bought a different one.

Edit: Checked the white paper and it doesn't even mention quick charging support. Seems Sony isn't making a big deal of it, even if Qualcomm is. Weird.
[Xperia Z3 General] Bäcker:
somebody tested a 2A or 2.5A USB charger and got the same charging times as with 1.5A charger.

using that same 2A/2.5A (dont really remember) charger via magnetic dock actually decreased the charging time

thus the 1.5A limit as an educated guess based on these findings
[Xperia Z3 General] jonmorris:
But a Quick Charge PSU communicates with the phone to say 'Hey phone, do you support QC 2.0 and want more juice?' and the phone presumably says 'yes please'. Without that communication, it doesn't support the faster charging.

I am sure Sony will release a suitable PSU in due course.
[Xperia Z3 General] Bäcker:
I read that the first time you wrote it. Obviously that is not the only solution (9V@2A) as Oppo is using 5V@4.5A for their Find7.

I fear your hope of sony releasing a quick charger is just wishful thinking.

But we will see, I would really be happy if I were wrong.

/edit

from the teardown

maybe there is hope. although just the PM8941 does not necessarily mean that the rest of the hardware is able to route the higher current/voltage
[Xperia Z3 General] jonmorris:
Sony doesn't seem to mention Quick Charge 2.0, but Qualcomm does. I am not sure why. Did Qualcomm get it wrong, or is Sony simply not (yet) choosing to take advantage of the hardware by bundling a compatible PSU - keeping costs down?

Given Samsung made a big deal of faster charging, I am flabbergasted that Sony isn't coming back at Samsung (and everyone) by saying 'We have it too!' and saying all you need to do is buy a specific charger.

I think I'll need to ask Sony, although I suspect the PR route will not be very helpful.
[Xperia Z3 General] Bäcker:
Sony included all the necessary Qualcomm components, that might be enough for them to list the device as supporting that feature.

Still this does not mean that it's actually supported. Either somebody gives it a try or we hope for an answer from the sony support.
[Xperia Z3 General] PunishedSnake:
Better than my m8 it seems

---------- Post added at 09:02 AM ---------- Previous post was at 09:01 AM ----------

Does it support quick charge 2.0?
[Xperia Z3 General] seqas:
yea totally agree the battery life is really outstanding. got my z3 yesterday i chose the compact since i read from

few expert reviews online that atm it would be better value either way would have chosen it anyway im not much into bigger phones

tried testing (small test with battery obv) z3 compared to my htc one,samsung galaxy alpha and the iphone 6.

none of them is near the z3. . i am really surprised so far with the phone all in all and im quite picky when it comes to that.

downside (for me at least) is all this crap/crap apps they are putting into them lol.

e:

i never had an experia before. so might be more surprised

from what i read @ around the internet, quite many say that its not that big of an upgrade if having the z2
[Xperia Z3 General] henihazbay:
Can you list the apps that you're using? There is no way I can get to that many hours.

What services did you compromise?
[Xperia Z3 General] jonmorris:
It would seem rather odd NOT to support something if you've included the hardware. I expect Sony will release a faster charger at some point, and may have already shown an intention to do so.

At MWC in February, I picked up a catalogue on the stand that showed loads of accessories for the Z2 - which included the Qi charging case & plate, keyboards for the Z2 Tablet and other stuff. Some of which I am not sure any tech sites even reported on, as it wasn't in the press releases put out by Sony or mentioned in the keynote.

So, there may be accessories for the Z3 still to be released. Fingers crossed, although as soon as I find any other Quick Charge 2 PSU I'll probably be buying one to try out for myself.
[Xperia Z3 General] zujko:
Stock rom, without root, stamina off, 3g/wifi...
[Xperia Z3 General] Bäcker:
yeah, as odd as not advertising such an important feature. Please report back once you tried the quick charger if you can get one. I'm very interessted in your findings. I would also happily be shown that my assumptions are wrong.

Until then it's better to be a bit more conservative instead of telling people their phone can quick charge. Could end in disappointment. You can still play the "I told you so" card when it has been established ;)
[Xperia Z3 General] jonmorris:
https://www.qualcomm.com/products/snapdragon/quick-charge

Go to the search feature and the Z3 is there. I doubt it's a mistake, but you can see Sony isn't yet approved as having made a compatible charger!

The Z2 is also listed as 2.0 compatible too!

I have absolutely no drain using Smartwatch 2. Seems a bug with Android Wear.
[Xperia Z3 General] vittogn:
Your mobile signal is quite weak.

In my experience even a 3 bars zone (compared to a full 4 bars) makes a big difference.

In my opinion this phone suffers mobile signal more than others and get quite warm even when the screen is off.

It would be good to post the screenshot of a day with your watch connected vs a similar day without it (like i did it here).

At this stage using an Android Wear watch is almost impossible with this phone.

My LG GWR is running almost vanilla with no apps and with fit disabled.

Android Wear app is not listed and BT is around 5%.

Thanks for your help.

[Xperia Z3 General] Jaimesco12:
Been using it all day. Even when I get 24 hours of usage the max on screen time is 4 hours no more. I guess I have a faulty device
[Xperia Z3 General] smala:
look at the second image... your signal is very low in most situations.

Last, but not least, your "keep active" time is equal to your "screen on" bar.

I think you just use you device heavily

Correct me if i'm wrong :)
[Xperia Z3 General] vittogn:
What did you do in the morning? Listen to music? I see some good time with your device active wile the screen is off. The rest of the day is quite good from a deep sleep perspective. If you were not listening to music, it like you had an app in the background working and draining battery.

I think that the main reason is you signal in LTE. I found that if LTE signal is not very good, the phone will drain like mad to seek for signal. Did you notice the phone to be warm wile sitting on the table?

I gave up and moved to 3G, using LTE only if I really need and where the signal strength is good. Try a similar usage with 3G ane report back.

In my experience a bad signal, hit the battery life of this phone more than other flagships I used.
[Xperia Z3 General] vinnyutd6899:
Does anyone have stamina mode on all the time?

if so does it really effect battery life that much? also are the any negatives to having stamina mode on all the time?

also does anyone use greenify with stamina mode? do they work well together?

thank you.
[Xperia Z3 General] Jaimesco12:
Might be the area I am in I always get new phones and have horrible battery with all of them. My wifi router stopped working but I'm getting another one tomorrow and turn on wifi calling and see if that helps. Should I change to hspa + or to edge since I have the t-mobile variant of the z3.
[Xperia Z3 General] Artood2s:
Try uninstalling that Snapdragon battery saver app, and note usgae for a couple of days. Could be causing conflicts with Sony's stuff. I get around 2:30-45 minutes screen time (accounting for about 50% total battery life) while at work with no signal 30% of the time, and then around 3:30 when I leave my office building (good reception then wifi at home). T-Mobile 6616.
[Xperia Z3 General] Jaimesco12:
Actually I barely installed the snapdragon battery saver app. The battery life has been terrible even before that
[Xperia Z3 General] Warmo:
the best battery life i've gotten out of this phone till now.

i only stayed home, connected to wifi 90% of the time, stamina mode on, greenify on (non-root), brightness on auto.

usually i can get 6-7 hours of SOT which is fantastic.

come to think about it it's tragic. i spend 4-5 hours of my day staring at a phone screen.

i should live more :(
[Xperia Z3 General] jrockwell:
Best battery life I've ever had on a phone, rooted or unrooted. I get 15-17 hours on mobile network, moderate to heavy usage. It's the first phone I've been able to leave the house with in the morning and know that I can do whatever I need to do on it, and entertain myself during downtime, for the entire day without having to worry about the battery running out. One thing I have found that has made a big difference is that the Facebook app and Facebook messenger app, due to all the data and info mining they do, use a lot of your phone's resources. Getting rid of these (I use Boat browser for FB) has made a huge difference.
[Xperia Z3 General] Angelo_92:
Hi,

I have this great smartphone since last Tuesday. Till saturday the battery life was really good;every day it reached at least 6 hours of screen on time.

From yesterday it seems that the battery drain is greater;it can reach only 5h15min/5h30min... I can't understand why!

I attach here 3 screenshots of the situation before and 3 screenshots of the situation after the excessive battery drain.

What could be the problem?

I usage has been the same(Chrome, Tapatalk, Facebook, WhatsApp)
[Xperia Z3 General] subhani:
I have used stamina mode all day a couple of times. It was EXCELLENT for allowing your phone to sleep better, increasing standby time BUT...

My screen on time is still approx' the same, even with stamina on. This makes sense since stamina mode isn't changing the way the display uses up battery juice. It just stops most apps from pinging you in the background with notifications. I am a heavy user so standby isn't very useful for heavy users. But if as a heavy user, you want a break from the incessant whatsapp notifications, then stamina is bliss bro.

And no, I don't use greenify or WiFi much. I'm always on HSDPA or a little bit of LTE. Location on battery saving. Google now enabled on all screens. WiFi location based scanning enabled. Full shebang basically. Best I squeezed was 7.5 hours. Recent best was 6.5 and the most common result for me is actually 5.5. Almost always 5.5.

Considering the battery standards of this phone, would this be considered good battery life? View attachment 3169906View attachment 3169907
[Xperia Z3 General] vittogn:
Yes I'd love to have such result.

Consider that when you'll connect to a mobile network and/or add/allow push services (your phone always sleep when the screen is off) your result will be worse.

[Xperia Z3 General] vittogn:
I see you point.

My argument was that when the phone is used on the go and with push services not blocked by stamina (I use stamina but I leave all messaging and email apps pushing updates).........the result will be much worse.

My view of a phone usage is on the go, as when you are in a static environment (home or office) a pc or tablet is much better.

That's just my point....
[Xperia Z3 General] subhani:
That's not bad at all but according to a few people here, they get more. Somewhere around 8 hours. Online reviews peg it around the 10hour mark. I believe the online reviews do tests using WiFi only so that may play a role.

My own experience is very similar to yours. I believe that is what MOST people are getting, but not all of us.

Hit THANKS if I helped! From a Sony Z3 via Tapatalk.
[Xperia Z3 General] Prasad:
Cool! Great to know. And yea, I spent a few battery cycles and factory resets figuring out what was causing the phone to stay awake even when the screen was off. High accuracy location (GPS), Google now and Google location reporting are the culprits.
[Xperia Z3 General] vittogn:
I noticed that as well.

Are you on battery safe mode?

Did you completely stop Google now?

Inviato dal mio D6603 utilizzando Tapatalk
[Xperia Z3 General] Prasad:
Since the last factory reset, I've not enabled Google now. It seems to continuously keep polling location. I've enabled stamina mode the whole time. Also, I've kept my live wallpaper. Not sure what exactly you mean by battery safe mode..
[Xperia Z3 General] vittogn:
Under location (than can be on or off) you have 3 modes: High precision, battery save and device (GPS) only.
[Xperia Z3 General] Prasad:
Well yeah, I'm using battery saving location mode.

Will test today with high accuracy mode to see if the battery drain and wakeup during sleep reoccurs. Just because GPS is on doesn't have to mean that it will necessarily be used. It was mostly the Google services constantly abusing it.
[Xperia Z3 General] infinitylook:
Don't use battery saving since it will consume more power compared to device only.
[Xperia Z3 General] Prasad:
I switched to high accuracy now. But I keep location turned off until I need it and then turn it back on from quick settings.

EDIT: You're right.. Device only works better. I've kept location always on this way. It's only polled when needed so long as all the overly demanding Google services are denied.
[Xperia Z3 General] melogray:
So I finally found some time to sit down and write this post...

Anyways, I am currently on my third Z3 and ever since I got it I had pretty big issues with battery life which was much worse than with my last two devices. Even with light usage it barely lasted throughout the day and barely got more than 5,5 hours of SOT with a single charge. First I assumed the battery needed some charging cycles but it didn't really get that much better, so I tried reflashing the firmware.

Turns out there actually was something wrong with the software causing the battery to drain faster than normal. After I repaired the phone using Sony Bridge for Mac I charged it to 100 % and pushed it to its limits in terms of SOT. These are my results for one single charge, display set to 50 % automatic brightness. :victory:
[Xperia Z3 General] mmoon24:
Do you have any push services or apps used when you did that?

I haven't done anything new with my phone, but when I went to Chicago for fun, I was getting amazing sot. Had phone off charger for 15 hours with 2.5 sot and 60% battery left. That included using google maps for 15 minutes, picture taking, checking into places via fb, and mms'ing pictures.

Back in Dallas, and my battery is back to normal. Doesn't matter if I am outside or at home with WiFi lol. Average about a little over 4 hours of sot.
[Xperia Z3 General] Prasad:
I concur with your experience. Initially, the phone's battery life didn't seem promising irrespective of how many ever battery cycles I did. After a firmware reset from the Sony PC companion however...
[Xperia Z3 General] vittogn:
What is a firmware reset using pc companion? Is it that different than a factory reset using the phone or flashing the image wiping data?

Tx.

[Xperia Z3 General] Prasad:
It's the equivalent of flashing the factory image, wiping data. That's precisely what PC Companion does if you select reset firmware.
[Xperia Z3 General] vittogn:
That's impressive.

You moved from 5 to 10 hrs SOT with the same set of apps and settings (locations, push services, Gnow.......)?

Thanks.

Inviato dal mio D6603 utilizzando Tapatalk
[Xperia Z3 General] melogray:
Sure. Mainly WhatsApp and YouTube, but I did a lot of stuff actually. I had to reapply all my settings which took me some time, browsed the web, lots of social media, organized my photos on the phone, cleaned out my e-mail inbox, some shopping on Amazon, pretty much anything that I personally consider as daily usage.

This is why I love the Z3 so much. The battery life is just out of this world. With other phones I always felt like I need to cut down my actual usage to get a decent battery life and I ended up disabling so many features and apps that I actually wanted to use. I mean, what the heck? What's a smartphone good for if I can't use it the way I'm supposed to?

The Z3 allows me to set everything just the way I want it and it still outperforms any other phone I've ever had and even exceeds my highest expectations. It's just hugely satisfying to know that your phone follows your demands, not the other way around.
[Xperia Z3 General] vittogn:
Very good post. I agree.

Unfortunately at the moment, in order to safely arrive at night (4 hrs SOT) with the charge I have to:

- avoid LTE

- use Stamina for apps but 10 must have push services

- south down Google Now

- avoid (like hell!) connecting my Android Wear watch

- avoid location high precision mode

I hope for lollipop to increase my experience.

2840mAh for the HTC I believe which is not too far off of from the Z3, also I thought that the static memory thing was common after the LG G2, which was its touted battery saving feature... I would expect HTC to include it as well, though I could definitely be wrong.
