Second day...

Took it off the charger yesterday morning, was concerned about battery. Here is what i'm looking at now. Left screen on for the last 1.5 hours to just test it, while downloading a few apps and messing around. Location services off. Based off just my own ancedotal testing, I believe something else was causing my battery to drain. I do think it is the mobile signal as my battery only drained 4% points overnight with 8 hours of sleep.

Does anyone know what the colors (see attached image) mean when it comes to mobile signal? I'm getting 4-5 bars of LTE almost everywhere I go.
[Xperia Z3 General] abhinav.tella:
Check data usage, some draining apps don't show up in battery usage, but in the data page they can show up. My dad's M8 had a weird YouTube issue where it somehow drank up LTE data even when not used, and battery sucked (Yes background data was restricted). After disabling it everything was back to normal.

My dad's issue turned out that another news app, used YouTube for caching, it never showed up in data usage or battery stats but was the vampire.

We uninstalled the news app and turned YouTube back on and the issue was gone. So see if you have similar vampire apps.
[Xperia Z3 General] mmoon24:
Nothing like that. Any data usage has come from the apps I'm using.

I'm going pretty hard on my battery today, so we will see what the results are. Do you guys have your battery start draining from 100 rather quickly, or does it stay at 100 for a while before running down?
[Xperia Z3 General] subhani:
Mine drains quickly from hundred until 98 or 97 then drops gradually like my normal

Considering Exchanging...

Well, here are my results for today. I listened to music via the Walkman app for about 1.5 hours, SoT was 2.25 hours using mostly for about 15 text messages, chrome, customizing, Reddit, and a 3 minute youtube video, and I was left with about 58% battery. Not really impressed. Double that essentially, leaving me with 16% battery and 4.5 hours of SoT.

Edit: Also tested if signal was an issue by going into airplane mode for an hour. Was listening to music at the time, and lost about 2% battery in that hour.

I just finished charging it and did a factory reset.
[Xperia Z3 General] Allesa:
From my early experiences with z1 and z2, Sony by default turns on fast dormancy, a feature that if your carrier supports it it will save you battery life. However if your carrier doesnt, it will have a serious impact on battery life. (thousands of wakelocks a day)

Sadly, it can only be turned off by altering fd_custom_conf.txt in /etc/fast-dormancy which needs root to do so. Full explanation here: http://xdaforums.com/showthread.php?t=2382680

If you are rooted, you can try that. If not, you may need to decide to hold on to whatever battery drain you got now for an exploit, or unlock your bootloader away considering all the things you will lose.
[Xperia Z3 General] mmoon24:
Should I exchange?

Factory reset my phone last night, had my apps re-downloaded, but did not open any them. Only synced up gmail. Decided to go "stock" for the most part with location services off. Battery did not drain a single drop overnight as I slept after I unplugged it. From the morning on, this is how much my battery drained in about 9 hours.

-Streamed a 30 min show on 4G LTE

-2.5 hours of walkman music

-3.5 hours of SoT: Primarily Reddit.

-30 text messages

Double that, and I get 7 hours of SoT in "18 hours" of being at the office. Again, this is with no accounts synced except Gmail. No location services. Nothing. I'm considering if I should exchange it or not.
[Xperia Z3 General] serv380:
? man
[Xperia Z3 General] mmoon24:
I tried to exchange my Z3 today for another one at the T-Mo store. Despite all the evidence I brought (a lot of your screen shots and what you guys were doing with the phone + Sony's official testing methods), they wouldn't take my phone back, because it wasn't "defective". The manager will not be in until Monday, so I'll have to wait for that.
[Xperia Z3 General] abhinav.tella:
Well if it really did have a bad battery it qualifies as defective. However there are many things that can lead to bad battery life.
[Xperia Z3 General] mmoon24:
Yeah, they ran some proprietary test by plugging my phone into their computer and found nothing. Like I said in my previous posts, I've ran various experiments on how to use my battery and for the life of me, can't get it past 5 hours of sot.
[Xperia Z3 General] dashrink:
My stats from yesterday. Not bad I might say, but the SOT varies sometimes from 6 to 10 hours on a full charge.

Stamina mode OFF, wifi & Bluetooth always on. Exchange & Gmail sync on, location enabled on battery saving.
[Xperia Z3 General] darkrai:
Anyone here tried any lollipop rom?

Can they please post their battery results?
[Xperia Z3 General] abhinav.tella:
Yeah 6-10 hours SOT with everything on is normal, same.for me here.
[Xperia Z3 General] fonetalk:
I had my phone a week. Having many battery problems my bat temp was sitting at around 35d when in use. And getting between 4-5hrs sot.

But my phone supplier sent it back saying they found no defects.

What more can I do, I've already been without my phone for a week.
[Xperia Z3 General] dedei:
For everyone having battery issues, maybe it's due to fast dormancy. I know mine has an issue because it drains a LOT when mobile data is on, even without using it.
[Xperia Z3 General] sphinxy:
Instructions on how to turn it on/off for our phones [MENTION=4449710]dedei[/MENTION]?
[Xperia Z3 General] dedei:
You can't, unless it's rooted.

:crying:
[Xperia Z3 General] fonetalk:
I'd say mine is battery related. If the screen wasn't used my battery would be great.

View attachment 3053712

As shown in image it's 70% screen usage. Even with auto brightness set low. Only get 2.5 sot with 45% batt drain
[Xperia Z3 General] sphinxy:
Are you doing anything CPU intensive?
[Xperia Z3 General] Allesa:
May not be so mate... From previous experiences with phones that have fast dormancy feature on (samsung s4,s5, z1,z2) , turning fast dormancy off could mean an additional 1 hour sot or more.

Unfortunately no Indonesian carrier supports it yet they send out phones with that feature turned on.

If im not mistaken, even during screen on, fast dormancy still drains your battery. Your phone continuously looking for that feature in your carrier with no response as your carrier doesnt support it. Screen on or screen off.
[Xperia Z3 General] dedei:
I can't see your image... GSAM is a good app to track your battery. I can see that my phone never enters deep sleep when mobile data is on.
[Xperia Z3 General] undercover:
I get about 4h sot in 24h with heavy use on a mix of WiFi /network data + often streaming with screen off. GNow enable and the rest of the crap enabled too. Not bad I think, but 5h would be spot on. LG G3 was quite a bit better when screen was off, much lesser battery use.
[Xperia Z3 General] Jonathan-H:
That's actually really good battery time. Listening to music will batter your battery and 7 hours screen on is good.

Accounts syncing won't actually have much impact on your battery unless it's picture backups.
[Xperia Z3 General] rashidramli:
This is what i got for the first full 100% battery charge. Brightness at 1/4, auto. Location set to battery saving. Google location reporting off. Disabled some sony apps. No power management used. Wifi/advance/scanning always available untick. Only getting push on gmail and whatsapp. Do some youtube, facebook(fast) and twitter(twidere).

Im really liking the battery life. Upgrade from galaxy nexus. Hmmm really interested to see the battery life with those custom rom. Lets hope for the best peeps!
[Xperia Z3 General] fonetalk:
I'll try and upload image again.

I'll try fast dormancy, how do you turn it if on these phones. Bit my only real drain is the screen. With screen of o get drain off 1% every 2.5 - 3 hrs which seems acceptable to me.
[Xperia Z3 General] dedei:
You should try GS AM battery app, it gives you a better insight on what's actually using your battery.

You can't turn fast dormancy off unless you're rooted.
[Xperia Z3 General] fonetalk:
Yeah I have gsam. It's really just screen use. Plus phone gets hotter as soon as I'm using it. Likes to sit in the mid 30s degrees Celsius. Or 95d Fahrenheit
[Xperia Z3 General] undercover:
Battery or CPU? For battery that's a bit hot, for CPU that's well cool.
[Xperia Z3 General] fonetalk:
It's battery. That's all im monitoring. It gets quite hot at the top near the NFC button.
[Xperia Z3 General] undercover:
With normal browsing on WiFi battery normally sits around 30-32c. On data can be more. Gaming - more.
[Xperia Z3 General] rxil:
The Mobile signal seems to be what is killing my battery. From the screen shoot the signal bar is mostly gray and battery drain is significant but when I'm in the green my battery declines slower.
[Xperia Z3 General] dedei:
You guys should check the keep awake time on GSAM. Rxil, you might have an app trying to sync while your signal is poor, making the device stay awake continuously... Or maybe it's the fast dormancy thing
[Xperia Z3 General] khhhhris:
Coming from the One M8 battery life on the Z3 is substantially better. Get about 1.5 days consistantly, moderate use. My favourite device i've owned so far.
[Xperia Z3 General] SweDunda:
Latest run. 5 days. 5+h screen . Sync on. ect
[Xperia Z3 General] CentaXx:
I don't even dare to ask how you did that. :eek: This is incredible.
[Xperia Z3 General] Shudder123:
what was your usage like? and how do you like the dual sim version?
[Xperia Z3 General] KarimSalloum:
Average usage mostly. Mobile data all the time, no wifi, no bluetooth, no stamina. The battery life will be even better once we have root and can fiddle around :) the Dual is good, it's exactly the same as the D6603. I only got it because the single SIM isn't out yet in my country but it can't hurt to have that option.
[Xperia Z3 General] Chefproll:
Now for some real practical data...

Endurance

Setup: 1 hour of 1080p YouTube video via WLAN, one brick wall between router and Z3, Z3 lying flat, no energy savers active.

Low brightness: 13 % per hour

Medium brightness: 15 % per hour

High brightness: 25 % per hour

Charging

Setup: Charging for one hour, Z3 switched ON, Screen OFF.

USB charging via Sony original power adapter (1, 5A): 33 % - about 3 hours for a full charge

USB charging via Samsung power adapter (2 A): 36 % - about 3 hours for a full charge (power adapter coded, thus no full power via USB)

Charging via DK39 "docking station" using Samsung power adapter (2 A): 50 % - about 2 hours for a full charge (full ampere rating)

(Yes, DK39 DOES work if you remove the plastic spacer (for use with Z2 tablet) and insert a thin piece of cardboard or similar as a distance piece at the back of the Z3.)

So stop whining about long charging times; buy a "docking station" and a better power adapter - and there you go.

Same for magnetic chargers: Use a low ampere charger - waste time. Use a better charger - be happy.

But I would not recommend trying charger ampere ratings higher than 2 A: Either the charging current will get restricted - or your battery toasted.
[Xperia Z3 General] Bäcker:
The battery should not get toasted. The charging circuit will only allow the amperage it has been designed for.
[Xperia Z3 General] fain2daniel:
Wich is what amperage exactly in this case?Is Quick Charger EP881 coming in box or sold separately and wich amperage do we need to charge super fast with no risk on Z3 ?
[Xperia Z3 General] Bäcker:
I do not know. We could only find out by hooking up a lab power supply and then increase the current until it stops.
[Xperia Z3 General] Chefproll:
We just don't know the maximum charging current. This totally depends on the battery type used in the Z3.

Maybe it's a little more than 3000 mA, maybe twice that much.

But I'd regard 2,5 A as a maximum value because the Z3 is sealed, heat cannot escape easily. The more amperes we squeeze into the battery, the more the temperature will rise. Charging circuit will lower the current to protect the battery from overheating - this kind of battery usually dies if temperatures rise beyond 60 °C.

So a pretty high amperage stresses the battery, but won't cut charging times dramatically.

Thus my 2,5 A guess.
[Xperia Z3 General] Bäcker:
2,5A is conservative and most likely very safe. Lion batteries do not really heat up much during charging. Oppo uses a 4,5A PSU for their comparable battery (this is with quick charge). It's true that high temperature degrades a Lion battery much faster than anything else. The battery will not die at 60°, most are rated for discharge at 60° ambient maximum (thus actual battery temp can be higher) - but it's advisable to keep the temps low to prolong battery life.

Still, you can rest assured that the maximum allowed charging current is hard coded into the charging circuit and it matches what the battery can take. Otherwise this would result in magic smoke, lawsuits and a batterygate Sony would rather avoid.

It's also important to note that a Lion battery does not charge with the maximum current all the time, only just until it hits around 70-80%. Then the charging current drops considerately and the rest of the charging process continues much slower. The reasons lie within the chemical processes involved with Lion charging.
[Xperia Z3 General] jonmorris:
After Samsung made a big deal of fast charging on the Note 4, presumably meaning it comes with the right PSU, I was surprised to discover on the Qualcomm site that the Z3 (all the Z3 models in fact) also supports Quick Charge 2.0.

But the phone doesn't come with the right PSU to take advantage of it, does it? Or if it does, it might be like previous Xperia releases where some retail boxes have a more powerful PSU than others (think back to EP800/850 on the Xperia S which was one of the first models to support the first version of Quick Charge).

Anyway, I've seen Motorola's 'turbo charger' on sale in the US on Amazon, but any ideas where to get one in the UK/Europe?
[Xperia Z3 General] corallus:
What brightness levels on these screenshots?
[Xperia Z3 General] zoomee:
Battery tests so far have returned pretty flippin awesome results! - This is from two days of solid use - still got 30% left:

According to the device I still have a fair bit to go lol!:

Obviously the battery isn't optimised yet either so I'm assuming its still to get better from here.

Oh and all that is with all power management stuff turned off!

REALLY glad I got this phone and didn't bother to wait for the Note 4 - bargain at £420!

Battery is still going strong - 23% left and showing 8 hours (1day 10 hours in standby) still left!!

Useage as follows:

Brightness was set to Auto (think its half way by default) and in terms of use:

Regular Wotsapp

Constant Push emails (I get a lot!)

Sony Playstation App useage about an hour in total (app is always running)

Destiny App useage about half an hour in total

DME Excitor email useage - running for 4 hours and receiving work emails

I have the NZBAir widget constantly running (polls my sabnzbd box)

Calls I only had two calls per day - each about 5 mins

Was connected to WIFI all day saturday, sunday I was out from 13:00 until 21:00 so was connected via 4G

Lets not forget the fiddling and showing off new phone bit to colleagues, friends and families either ;) - I'd say more use than normal

Did I miss anything? lol

- All in all I was pretty impressed. My S4 would have died within one day normally.
[Xperia Z3 General] chesterr:
Auto sync and GPS? Were they on?
[Xperia Z3 General] zoomee:
Yes Auto-sync was on, GPS was set to Location services enabled - High Accuracy.

Only change I had made to Power settings was to disable Queuing of background data.
[Xperia Z3 General] Jiyeon90:
What was the screen on time?

Sent from my Xperia Z2
[Xperia Z3 General] zoomee:
At the time of them screenshot (10:30AM today) it was 4h 57m 24s

I am currently down to 16% battery - Estimate Battery left 5 hours (1 day in Standby Mode)

16% = 2d 9h 3m 47s on battery, screen time= 6h 6m 27s

Thats nearly 3 days of battery life without any power management features! :)
[Xperia Z3 General] maverick1103:
You are getting better stats than me zoomee, I'm getting great battery life just not as good as yours...

This is after 3 charges...please note I'm a heavy user and my signal wasn't great during my commute this morning and on way home. I also play Ingress, which heavily uses data and GPS, also brightness was set to 50% with adapt ticked.
[Xperia Z3 General] chesterr:
Guess you're not using 3G/4G that often. I am actually thinking of upgrading from Z2 since mine is kinda bricked,(something's up with the Boot IC)
[Xperia Z3 General] Shudder123:
just curious what your Screen time is?
[Xperia Z3 General] maverick1103:
At that point it was 4 hrs 10 minutes.
[Xperia Z3 General] golemagg:
Does the Z3 support quick charge tech b Qualcomm? Which charger do we need to take advantage of it?
[Xperia Z3 General] mmoon24:
Battery seems to have stabilized. Turned off auto-sync, phone dropped 1% overnight after 7 hours of sleep. Got 2 hours of SoT strictly using Chrome on Wifi. Do the math, and you get 8 hours of SoT. However, I lost 45% of my battery with 1.5 hours of SoT when I was at the office with a mobile signal. Phone is constantly going back and forth between 4-5 bars, and it shows on the graph as it is mostly orange/purple.

I still don't know how some of you guys are getting 10 SoT though.
[Xperia Z3 General] SweDunda:
The fuuny thing is, I have done nothing. No tweeks at all. My Z3 seems to have better and better battery life. The phone is ~8 week now. :)
[Xperia Z3 General] abhinav.tella:
Yea mine took about a week to get calibrated with the same use in the begining I got about 5Hrs SOT now 7-8 Hrs.
[Xperia Z3 General] yeehc:
Recently i noticed my Z3 would drain about 1% per hour during sleep, also battery dropped from 100 to 99 in 2 mins, been using it for a month now..seems like battery is getting worse in my case:(
[Xperia Z3 General] CentaXx:
My Z3 arrived yesterday with 50% charge, as my old phone number is transferred tomorrow to the nano sim (i hate it!), i had to use 2 smartphones today - the Z3 and the One M7.

One for mostly whatsapping, screen on time 40 minutes - battery left 20% (i know, there's something wrong with the rom i'm using)

Z3 for everything, playing around, taking photos, screen on time 4,5hrs - battery left 35%

I have to say that i "stressed" the Z3 a bit, 1.5 hrs of maps navigation + 1.5hrs spotify LTE streaming. Display not always on. It's the first smartphone i don't have to plug in my car charger for an one hour drive - it used maybe 15-18%, so what? My One, on it's best days (and they're far over) made 4hrs screen on time, with heavy usage such as navigation + LTE streaming it would have lost at least (!) 35% battery. I'm amazed of the runtime i'll get over time. I'll update with screenshots after i settled a bit with the phone and G Sam has calibrated the average screen on time etc. (at the moment it's saying 7hrs - would be great if it stays this way ;) )
[Xperia Z3 General] abhinav.tella:
In my testing I found "Tap to wake" made almost no impact on battery for me, just like on the LG G2. I also have location, autosync on and I still get about 6-8Hrs SOT in a 24Hr period.

So for those of you who are wondering, its fine to use it. Its more convenient than the pressing the power button which is too resistive.
[Xperia Z3 General] Artood2s:
Weird, my power button is smooth as butter. Turned off tap-to-wake because the phone was waking up too much in my dress pants. The pocket liner is aparently too thin, and I would rather not have the screen facing out just in case.
[Xperia Z3 General] oceanax:
I'm only able to get 4 hours plus screen time out of my Z3 ( very heavy gaming ). I also notice that my battery drop like 1% every 1.5 hour or so. Anyone having same problem like me? My phone is 3 days old.
[Xperia Z3 General] mias1:
I was having same problem till I changed preffered network mode (under mobile network settings) to WCDMA/GSM. Previously it was on 4g/WCDMA/GSM. My guess it was constantly trying to connect to 4g in a 3g only area where I live.
[Xperia Z3 General] oceanax:
I'm using WiFi though. I was at home the entire day to test out the battery life. To my disappointment, it wasn't as good as my ex-phone, Note 3. On my Note 3(rooted), it's common for me to get 6 to 7 hours screen time. I haven't test our battery life for normal browsing messaging usage though :x For me gaming only give me up to max 4 hours plus screen time out of 100% full charge. ( Even my S3 can give me 3 hours plus SoT with heavy gaming :/ weird )
[Xperia Z3 General] abhinav.tella:
I get variable SOT between 6-9 Hrs in 24 hrs with location, autosync on, and even in reviews the Z3 always tops Note 3 which is also a great device.

Maybe you just need to let it settle and it will be better after a few usage cycles. In the beginning I would get just 5-6 Hrs SOT.

Also check the brightness, this is the brightest display on the market at around 800 nits so high brightness is not good for the battery. The Note is not anywhere near that even at full brightness (~380 nits) which, also if anything AMOLED eats more battery on web surfing due to white background.
[Xperia Z3 General] CentaXx:
I've mostly been browsing / FB / whatsapping the afternoon (was 100% charged before), have now 73% battery left at 3hrs 5mins display on time. I'm amazed! More to come..
[Xperia Z3 General] oceanax:
Aite! Will report back after a few days :) Thanks! That really clear my doubt! I always keep my display on the lowest with Auto Brightness if I'm outdoor. When I'm home, I switch back to the lowest setting for brightness display without Auto Brightness.
[Xperia Z3 General] fonetalk:
I've had my mine for 3 weeks now. Battery rarely get more than 4hrs. I've restored it and repaired it a few times still no improvement.

I sent it off to my telco and they claimed they couldn't replicate the issue.

So gave it back to me. I still think i have grounds for a replacement within the month off purchase
[Xperia Z3 General] sphinxy:
Have you tried stamina mode?
[Xperia Z3 General] fonetalk:
Yeah that accuracy makes no difference. Is all screen lit at 25% auto brightness setting. Usually actions 70%
[Xperia Z3 General] CentaXx:
It truly is INSANE!

I pushed it a bit after realizing it's now the second day with the battery. With that i mean, i used it all day to check FB while i was at the PC anyway and so on.

I unplugged 23.5hrs ago, have 9hrs 20 minutes display on time (!!!!) and have 7% left. I now have to leave and will use my car charger, otherwise i would have made 10 hours screen on time i guess.

Stamina Mode enabled (except WhatsApp + Threema), queued background data enabled, autosync ON, auto brightness @ ~20% (was always brighter than my old HTC One M7!!), ehm, what else to mention? Other than LightFlow made the notification LED blink all night. I really, really love it. I tripled my battery life!! I almost can't believe how long it lasts!

Keep in mind i only had the Z3 for 4 days now! I think i'll make the 10hrs sometimes soon, most likely after christmas when i have more time to play around with the Z3 all day :)
[Xperia Z3 General] isthatxavier:
I'm not the only one

I was worried as quick charge promises to charge 60% in 30mins while my z3 was charging just 30% in such time. I even swap the wall socket thinking the wire had issues. What worriea me although, the stock charger that came in with the z3 seems to overheat while plugged in.

Has anyone noticed that?
[Xperia Z3 General] infinitylook:
I guess z3 hasn't enable quick charge in the softwre side
[Xperia Z3 General] serv380:
Is this normal?
[Xperia Z3 General] fonetalk:
What's the screen on time?
[Xperia Z3 General] serv380:
When I took the screenshot it was 23 minutes

---------- Post added at 08:02 AM ---------- Previous post was at 08:01 AM ----------

23 minutes
[Xperia Z3 General] abhinav.tella:
Not bad I get any where between 10-13.5% drain per hour of screen time. The first few percent does go a bit quickly.
