Does this statement hold true if WiFi is not used at all? If it's just cellular data, can it really last with heavy use?

I honestly doubt it.

I got the OTA to .77 without reset and I have GNow enabled, location battery saver enabled, LTE only no WiFi and I consistently get 6hours tops. I HAVE had 7hours to 7.5hours in the past. Not sure how. Same settings honestly. I don't think it's the update at all.

BTW, I don't use stamina but que bgdata is enabled and so is location based wifi.

If you're getting only 4 hours. It would be your app setup. Or poor reception or both. Or you're gaming or using the camera a lot. Those two are the most battery taxing tasks the phone does.

I'm convinced that 99%of battery issues are due to either crap reception or apps misbehaving. If you show nothing keeping your phone awake, I guarantee that your signal strength is to blame.
[Xperia Z3 General] vittogn:
Thanks for feedback and help.

The problem is that is very difficult to understand which app is the cause, with no root.

From 98 to 77 I noticed an increased Android and OS Android factor, but no other specific app.

I'm on 3G 70% and wifi 30%.

Stamina with 10 apps white listed.

Location on to accurate.

GNow on.

NO GAME and Camera at all (just 2-3 pics per day).

3G reception between 2 and 3 bars.

With this set up I was able to do with .98 18h on battery and 6h SOT.

On .77 I was around 16h on battery and 3.5-4 SOT (same set of apps and settings).

Let me try to test with a fresh .98 install for 3-4 days, then I'll report.

---------- Post added at 09:00 AM ---------- Previous post was at 08:59 AM ----------

Do you have any advice in understanding how to detect the misbehaving app(s) on an un-rooted device?

Nothing is evident in the stock battery stats.
[Xperia Z3 General] tel033:
At first it was good for me two days easily but now (I don't know if it is .77 fw related) I get 6 hours Sot at best, brightness set at 35 percent, only 3g but not so good reception here, guess I can blame that, stamina mode is **** though, I set it so I can still review Whatsapp messages, but still it's kind of the same with or without stamina ?... Any comments or suggestions will be appreciated thanks!

Can anyone tell me if this is acceptable? I was downloading regional maps for Here Maps today and had full GPS enabled. I still had 40% remaining when I snapped these shots. I can't even break the 6-7 SOT threshold. I don't use stamina, hardly on WiFi, mostly LTE except for today, GPS on battery saver mode, no greenify or anything. I tend to enable brightness to higher levels after trying lower levels didn't seem to make an improvement.

[MENTION=4578981]tel033[/MENTION] stamina mode definitely works. I use Telegram instead of WhatsApp but I don't blacklist it. In fact, I only enable stamina mode to silence Telegram every now and again. Works like a charm.

I don't seem to be getting the battery life all of you peeps are :(

Yesterday, 2.5hr screen on time, had the screen dimness at aprox 20% all day, no phone calls, no gaming, no bluetooth aside from from my 20min commute to and from work, wifi at home from 6:00-7:30. got from 6:50am till 8:30pm until the phone died. Was on stamina mode.

Day before yesterday I got 3.0hr screen on time, had a moto360 paird all day, no gaming during the day, had a 10min phone call, and from 6:30am till 7:00pm I had 30% remaining. killed the rest of the battery playing games.

Took it off the charger this morning and in 20 minutes lost 10%.
[Xperia Z3 General] bioan:
I am absolutely positive you have a bad unit or using some crappy coded apps. I come from M8 and the battery is stellar on Z3. They are in a different league when it comes to battery life.
[Xperia Z3 General] undercover:
Yup, but for overnight charging I recommend usb port or low amp wall plug.
[Xperia Z3 General] abhinav.tella:
I got 9hrs SOT in 35.5Hrs as of last night with 4% left. I had location and autosync on, with WiFi calling. Maybe you have horrible reception or a bad app. I do not use any power saving modes.
[Xperia Z3 General] wired335:
How does one track down a "bad app"?
[Xperia Z3 General] xxquicksh0txx:
I agree, I came from an M8. I could barely get through a day with the M8, the Z3 easily lasts through the day. I've stretched it through 2 days.

Especially on the weekends when I don't use it as much, I can not charge it Friday-Sunday night.

[Xperia Z3 General] barondebxl:
I have had 6 M8, I install the same apps all the time and all of them gave me outstanding battery life. I'm not a pro with phones but one thing I know how to measure very well is battery life. I can tell you something is wrong with the Z3. And it isn't just me by the way, Detroitborg, famous YouTube reviewer has had a top 10 phones of 2014 recently, and the Z3 was one of the phones. He mentioned battery life as a con for that phone. It's not my apps its the phone itself.
[Xperia Z3 General] Luhccas-X10:
I disagree.

Had an M8 for a week and it don't even come close to Z3.

The maximum SOT was 5:30 hours with less than half brightness and without calls. And it never gave me 1 full day without charging.

Look to what i showed.

Xperia Z3 is the best when it comes to battery endurance.

Sent from my AWESOME Xperia Z3!
[Xperia Z3 General] barondebxl:
Well I have to disagree right back L. From my personal use and having installed the same apps, my M8 last way longer. Sometimes I have 75% at like 10 pm where my Z3 would be at 4%. Yes that much of a difference.
[Xperia Z3 General] Stixxbixby:
Detroitborg said he was disappointed with the battery life with the screen on FULL 100% brightness - I commented on it at the time...

Strange thing for him to say being that's the case with EVERY smartphone.
[Xperia Z3 General] Luhccas-X10:
I did the same thing.

Installed all my apps on M8 and it failed miserably.

I believe you had an faulty Z3 and me a faulty M8. Simple.

4%? Not even playing games for a long time it happened with me...

Sent from my AWESOME Xperia Z3!
[Xperia Z3 General] barondebxl:
Detroitborg also said that battery life was a con for the Z3, watch his top 10 phones of 2014 video.he didn't specified 100%brightness there.
[Xperia Z3 General] abhinav.tella:
Brighness makes a big difference, this is the brightest phone on the market at 800+ nits so the same brightness % setting on the M8 is actually less,meaning it will use less battery, however overall the Z3 screen is a bit more efficient. (My dad has the M8). Also try resetting your device to default, but before that try calibrating the battery.
[Xperia Z3 General] rxil:
There's a thread on here were a few people notice massive battery drain when pairing the phone with an Android watch.
[Xperia Z3 General] undercover:
No, it's that circumstances are different. Different apps, network strength, use pattern etc etc. I don't get 7h SOT either. Well, I have managed it before but in general I don't let it drain that low to find out. But, this phone does last full day with pretty heavy use. Not hammering with resource intensive games, just heavy varied use.
[Xperia Z3 General] Stixxbixby:
Sorry, but u r incorrect. I just watched the video again & he specifically say's that the phones weakness is battery, ESPECIALLY when used at %100 brightness. C'mon. 100% brightness - especially with the of-the-chart nits of this screen. That's an obvious statement for very atypical usage imho.

Either way your battery life is clearly not what it could be, so u should go back to the M8 if that serves u better. Good luck.
[Xperia Z3 General] vittogn:
Agreed, 100% with non auto is meaningless for this super bright and excellent screen. I'm always on auto @ 25% and I never got issue to see details even in bright sunlight. With my old G2 I had to put it on manual and 100%.

Comparison battery rundown tests should be done at a measured nit level, and not using at 50% or whatever %.

Can you please share the screenshot of your battery that gives the details of signal, gps, wifi, phone active and screen active. I'm impressed by your result and I'd like to compare with my much worse results.

Battery life is low

My average screen on time for the first few days was about 6 hours with a maximum of about 8 and a half hours. Now it's dropped down to this :/ I can't figure out what to do. I turned off auto sync for everything except my google account, turned on "Queue Background Data", tried a full charge, discharge and full recharge again, flashed it thrice (to different builds as well as the same), turned off double tap to wake, turned off NFC and it still gives a crappy battery life. Any ideas on what I can do?
[Xperia Z3 General] barondebxl:
Well I'm not incorrect. When he says especially, that means that even in normal brightness battery life isnt great, now ESPECIALLY in full brightness means it will drain even quicker which is to be expected cause of how bright it gets like you said.

But one thing is for sure, the Z3 battery life is not consistent. Look at the results here, some are getting great battery life and some are not. You cant blame everyone with a bad battery on the apps they have installed and things like that. Personally I always install the very same apps on all my devices, and from my personal experience the M8 smokes the Z3. I cannot kill the M8 battery in a day whereas sometimes I have to charge the Z3 around 8-9pm.
[Xperia Z3 General] wired335:
Yesterday was a lot better and a lot higher use than I've had so far. Phone in stamina mode, installed GSam Battery Monitor. SOT of 5 hours, got 20 hours of battery life before throwing it back onto charge (turned the phone off overnight). including in that was a few phone calls, google maps navigation for 20ish minutes, bluetooth audio streaming (1 hour+) listened to music with onboard speakers for about 2 hours (volume at 80%), a few phones, recorded a minute of video, not to mention the usual email, bbm, and facebook messenger. Also had my Moto 360 paird.

Seems to be that the battery is getting stronger and stronger every day/time I do a full discharge.

Best battery life out of any Android Phone ever made

I have owned every phone out for the last 5 years and this by far is the best for battery life. I easily get over 8 hours of on screen time and I am using Android wear, Wifi 95% of the time, not rooted, all stock. US 6603 Version on AT&T. Watching YouTube videos, Autosync On, Brightness 40% auto, some Netflix, Google music, bluetooth on 100% of the time, 2 gmail accounts synced, Twitter, Facebook, Greenify (not rooted version so manual hibernate).
[Xperia Z3 General] ConstantHeatCheck:
Has anyone been experiencing rapid battery drain during the first 10-15% after fully charging the phone (even when the screen is not on and the phone is in idle)?

I got the Z3 the last week of October from T-mobile and its been great, I was getting 6-8 hours SOT (depending on when i decided to charge). But lately (maybe past 3 weeks or so) I have been noticing the battery draining rapidly for the first 10-15% after being fully charged and then it doesn't drain so rapidly the rest of the time phone is not plugged in. I still get around 5:40-6 hour SOT which is still really good, but I haven't been able to reach any higher lately, even though i was able to only a few months ago. I used greenify to see if any apps were running in the background but didn't see anything out of the ordinary and I don't really use much other than Twitter, Yahoo Sports, Yahoo Weather, Gmail, and Spotify. Also my T-mobile signal has been good and I'm a on WiFi most of the time.

Thanks for any feedback!
[Xperia Z3 General] wessozin:
unusual usage?

Hey, used to have the same amazing batterytime but lately its been waning off

.. Cant really brag with 8 hr stamina mode and already at 58%.

. Normal usage with phonecalls and 4G turned on as well as bluetooth music streaming for like 1hr
[Xperia Z3 General] subhani:
So I got 6.5 hours of SOT. 90% on 3g and LTE. Lots of twitter, telegram, some YouTube, Chromecasting, couple of calls and several texts. Lots of browsing the web and reading articles. More than half an hour using as a desk clock. Location on battery saving. Google now on and detect hot word enabled for any page. Screen brightness on 40% auto. D6603 .77 firmware stock no root no greenify or battery saving apps and no stamina. Double tap to wake, led all enabled.

So my experience is the same as the guy from two posts above me. I DO see a quick drop from 100 to 99 and slightly slower drop to 90. Things level off after that but I guess this is quite normal.

My problem is that I average 5hrs of SOT and not 6.5 or 7.5 or 9hours like many here are getting. It's still excellent as I can burn through a day easily without ever worrying. But 9 or 10 hours would get me through two days. DOES ANYONE KNOW WHY I'M NEVER SEEING THOSE RESULTS?

Sharing my results

Hi all, I'm sharing here my results with various settings.

It looks like Location settings (High precision vs battery save) is making quite a lot of difference.

I'm on Stamina mode with 10 apps in the white list.

All results in colums H and I are projection of the 100%.

Column J is a sort of Index I created where I sum SOT + Standby Time divided by 4.5 (happy to have comments in this!!)

In the pipeline there is Wear test, LTE and then repeat everything with .77 fw.

Waiting for your comments and help on ho to improve my battery and/or test methodology.

I hope this can also help whoever is keen to improve battery life.
[Xperia Z3 General] vittogn:
Hi, your result is very good.

I wonder to understand how you can achieve such a good deep sleep, without stamina! Do you have any push service/sync (messaging, emails, news) enabled?

What about Google now and Locations?

What theme are u using?

[Xperia Z3 General] subhani:
Yes I have google now enabled plus google voice detection on any app enabled too.

I have location on battery saving and location based WiFi scanning enabled. Allowing Google to use location data.

The theme no longer exists on the play store but an identical paid one is available by the same dev I believe.

[Xperia Z3 General] subhani:
I think you're in a very bad signal area. My entire signal bar is full green, whereas yours is full of massive gaps. This is possibly also causing your phone to stay awake.

My only recommendation to test this theory is for you to use your sim on another phone that can do wireless hotspot and leave it on the wall charger. Take calls and messages there if you need. Connect your Z3 to it's WiFi or any other WiFi for ALL other tasks such as Twitter Facebook WhatsApp YouTube and internet browsing or reading or music playback. See how the SOT performs and if it achieves deep sleep.

My replacement unit from t-mobile has 4 hours of sot in a 48 hour span. That would be fine, but I get 4 hours even if it's off the charger for 22 or 16 hours.

I've actually had this one for over a month now haha. My first one I kept for 2 weeks and exchanged it prior to the return policy ending. I had the same SoT results. Didn't matter if it was barebones, no apps installed, wifi all day, airplane mode, whatever. I've tested both at their most minimal settings.

Even the Sony rep said there was nothing wrong with my phone lol. Convenient that Sony removed the battery health test from their *#*#7378423#*#* menu.
[Xperia Z3 General] vittogn:
I think that more importantly your phone never ever sleeps!! It is always active. You must have a bad app or some Google stuff running in the background.

Sugnal affects battery life so much in my experience, but in this case he ranges between 3 and 2 bars. That's not so bad.
