Actually tried the two days and got it. Last 15% was stamina mode on. Massively impressed
[Xperia Z3 Compact General] robertkoa:
Interesting.

So a few of you are getting great battery life,

a few are getting excellent and a few average to good.

Do the batteries themselves vary plus or minus 10% ?

Or , more likely are these usage/network/app variations ?

Experts - (which I am not ) what do you think ?

I'm no expert but I definitely think that it's more to do with your second point as individual batteries probably have negligable differences.

It's hard to normalise usage too as the system battery monitor doesn't show total mobile internet time as well as wifi. As you say signal strengh is an important factor, I'm sure this is why I've been pretty awful battery life on my Moto X 2013 vs a lot of other users. :(

To take it further, various reviews use extreme tests (such as phonearena) which possibly lead to some users getting the phone then being disappointed that it doesn't match what they've read.

I'm using the D5803 in the US with T-Mobile LTE. I've noticed it uses a lot of battery while asleep without stamina mode on. The top culprit seems to be Facebook app? Anyway, I usually leave Stamina mode on anyway.

I'm pretty impressed with the battery life in general, but I haven't gotten more than 4:30 screen time out of it. I've been using Maps a lot tho for navigation at full brightness.

^If you don't want to uninstall the Facebook app you could try disabling auto sync data and manually refreshing for notifications.

I am very impressed for the few days I have owned the phone. I don't have photos and whatnot but wanted to offer general comments. Brightness ~40%, screen on of 3 hours 10 minutes, 17 hours since charge, and still had 51% battery. Very pleased with the results. I was coming from an S4 with an extended battery, and it seems my battery life is at least on par with that.

On weekdays, My phone really lasts 2 days on 4g only with 8 hours of screen on time for browsing reddit and chrome.

I don't do much else but browsing on my phone at work, so it will differ than other people, but I am really liking this phone.

Never had such AWESOME battery life :)!

I'm getting 48+ hours between charges with 6 hours of screen on time. Mostly Gmail, exchange email (Nine), G+, texting, Tapatalk, etc. Google Now enabled, no Stamina mode.

Trying a couple cycles with Stamina mode enabled to compare.
[Xperia Z3 Compact General] der_yeti:
I have my Z3c for one week now. But I cannot get the lifetime out of the battery as most of you. Stamina is disabled. When I take the phone from the charger in the morning at 6 am, in the evening I have around 30% left, with a screen on time between 1 and 2 hours. Display costs around 40%, cell standby around 12, and standby mode around 8%. Android System, Android OS, Google Services, are around 7%. I already disabled most of the services and apps which I do not use and the X-Reality Engine is also disabled. Any hint what might cause the battery drain, or any app which can diagnose this?
[Xperia Z3 Compact General] wingsfortheirsmiles:
I think you'd need root but how about Better Battery Stats or Wake Lock Detector?

Could you also post your stock Android battery monitor screenshots too?
[Xperia Z3 Compact General] dorezen:
could it be that the cell signal in your area is not that great? that could be a culprit of battery drain.
[Xperia Z3 Compact General] FANdroid:
I'm getting a solid 2 days as advertised with normal usage and stamina mode activated when under 40% :good: Loving this phone so far.
[Xperia Z3 Compact General] Crewville96:
I get 2 days with no stamina modes. Very happy.
[Xperia Z3 Compact General] der_yeti:
I attached the stats from yesterday. Pretty disappointing...

Stamina Off

X Reality Off

Much Sony Software Disabled

Screet at around 50%

Usage mainly facebook, browser, Whatsapp

Cell signal is pretty good where I live.

One huge wakelock is the latest Google play services, uninstall the update in settings and you get some better battery life.

Thanks for the hint, I will try this tomorrow.

I am sure that most of you know, but just in case: there is a way to use wakelock detector without root! http://xdaforums.com/showpost.php?p=48149239&postcount=338

I am going to analyze this tomorrow in more detail and will give you an update.
[Xperia Z3 Compact General] Nplus1:
If anybody didn't already know this, it must be repeated over and over again!

I'm on the 4th or 5th charge and last time I tried draining the battery until the phone shut down. I could squeeze about 10 minutes of keeping the screen on, WhatsApp, etc out of the last 1% even though sometimes 1% drops in less than 5 minutes of keeping the screen on.

I'm getting about the same results: 60 hours on a charge (100% to 5%) with 6 hours of screen on time. 4G on, internet traffic about 50% on 4G and 50% on Wi-Fi, GPS high accuracy on (extremely fast GPS fix even indoors!), but Google Now disabled, App sync disabled, News and Weather disabled.

No Stamina mode.

I noticed about the same thing on the 2nd charge when the battery life dropped from great to less than average (17 hours on a charge, with about 3,5h screen on time before dropping below 10%).

The only explanation I can think of is a combination of Google Play Services update (as NisseGurra points out) and sync options. As soon as I disabled App Syncing, Google Drive Syncing and News and Weather Syncing (keeping everything else on), I already noticed a great improvement.

I also disabled Enterprise Services in Security -> Device Managers. I have no idea if this will have an impact on battery life but it closed a process I don't use so it can't be a bad thing. :P

I'm pretty sure the phone is capable of providing about 2 days of battery life with at lest 7 hours of screen on time if only you can manage the wakelocks and improve battery drain in idle mode.
[Xperia Z3 Compact General] Maroon Mushroom:
Getting about double the battery life from my Nexus 5.

Android L will only help things even more.
[Xperia Z3 Compact General] Brendan12695:
Ive had this phone for three days now and I have had the worst experience with battery. I don't know what it could possibly be, I'm letting it sit in standby and it goes down quite a bit very quickly. I've used both stamina and ultra stamnia and they still are no good. Not very pleased thus far. :/
[Xperia Z3 Compact General] nizarnoor:
My battery isn't that great either. It never was. It's been over 2 weeks now. I wonder what's wrong....?
[Xperia Z3 Compact General] UserX10:
I figured out, that the reson (for me) was that I had installed VLC. After several resets and try and error with some apps I could determine this App for draining my battery so fast.

I don´t know why, but it is so.

I had also installed VLC on my Z1C without any issues and have it also installed on my Z2 Tablet without issues. But on my Z3C VLC causes the battery drain.

Now I´m on about 2 day battery use with heavy using the phone (calls, play 10 minutes my RealRacing 3, instant massaging, sync on, g+ on, google now,...)

Give it a try.

If not, you have to go through all the pain I was going :) -> Reset phone and install app by app and wait half day and check the battery drain...
[Xperia Z3 Compact General] der_yeti:
To everyone with battery draining:

I had the same problem (see last posts), and figured the issue out based on the comments I got here. Now I am at 50% after 29hours, with 3hours screen on time without Stamina active!

Here is what you need to do:

Disable "Enterprise Service" under Device Administrators in Security Menu

Disable App Sync (and everything not needed) under Accounts - Google - your Google ID

Disable location report under Accounts - Google - location report

(I am not sure if the wording is right as my phone is german)

Those steps basically stoped my wakelock problem with Google Play Services. I am not sure if all steps are really needed, but the combination worked for me.

You will get even more battery life if you disable all apps and process which you do not need, including Google Search if you don't use google now.

I hope this helps.

[Xperia Z3 Compact General] greyhulk:
Thanks! I'm going to give all of this a try, as my idle battery drain has been ridiculous. A few questions:

1) Is app data sync important for your google account? Without it on, won't you be missing data if you restore from a backup?

2) Location services: Seems like every time I turn this off to fix battery issues, I end up needing to turn it back on for something. Doesn't it impact Google maps and Google now with respect to geographical awareness when you're looking for something near you and relevant notifications?
[Xperia Z3 Compact General] Eason85:
Yes, without the location service then no apps can access your location. That's the point. Turn it back on when you need it.
[Xperia Z3 Compact General] greyhulk:
We're only talking about location reporting here.
[Xperia Z3 Compact General] nizarnoor:
Here's my phone's battery performance today.

Now at 25%. It looks like it's been on for about 22 hours, with 6 hours of screen time.

[Xperia Z3 Compact General] Crewville96:
There's location (i.e. GPS, network) and then location reporting. You can have location on high accuracy, and have location reporting off. This is what I do.

[Xperia Z3 Compact General] FranzDages:
Here is my experience so far. I received my Z3c on Saturday afternoon with about 50% battery. I set everything up and synced everything and then didn't charge it much til Sunday evening. I did charge it for an hour or so just to make sure it worked. I don't remember what the battery level was when I plugged it in Sunday evening. I took it off the charger Monday morning, and now, 34 hours later, it is at 10% I haven't been using it heavily, but I have used GPS for 45 minutes to an hour each day. Also, Sunday evening I talked with my Fiance for about 45 minutes and the battery percentage didn't change.

Try BetterBatteryStats. Take a look into your wakelock and processor states statistics. Usually this should expose whatever is eating up your battery :)

You could search the play store, maybe you will find something similar that doesn't require root.
[Xperia Z3 Compact General] tudork:
I am posting my own observations:

- Battery drain while phone is asleep is great. It seems many people who are not happy with their battery time complain about this. Well, I do not have any issues. Yet.

- However, there is no way I am getting 6, or 7 hours screen on time. My battery seems to get empty when I am using the screen: browsing, reading articles, Flipboard, playing Ingress (but playing Ingress is a normal and expected battery killer, I am not surprised). But I am not sure how people can get 6 hours screen on time. I wish I was able to get the same.

- Stamina mode: I have it enabled all the time, but I put Viber on the white list. I was kind of surprised that other notifications were making their way through: facebook, whatsapp, telegram. Then, I tried to clear the white list so I have Stamina on, but no apps are given permission. Suddenly, I am not getting any notifications! Which would seem to mean that STAMINA works but it's trumped up by even one app on the white list. So basically, it seems that Stamina mode (at least the data mode) does not work if you have anything on the white list, because everything else comes through, too. I am not sure if this is right.

- when Stamina is really functional (meaning that I have no app on the white list), stand by drain gets even less.

All in all, it's hard to estimate if I have awesome battery or not. (it's definitely much better than my previous phone). I could quote 18 hours of battery going from 100 to, say, 60, hurray, yeah but 8 of those wore at night with zero activity on the phone, so it doesn't tell me anything.

In conclusion, I have better battery life than with my previous phone (except, of course, my Razr Maxx, bless its little slow and tired heart) but I am not getting Screen on time like some of the people here. I wonder why. Yes, no Auto-sync, no LTE, no bluetooth on, no Wifi on if I am not actually connected to a Wifi. Stamina on (but this is relevant just for stand by, otherwise it's off, right?)

[Xperia Z3 Compact General] Bobb_o:
I don't know what I'm doing wrong but I'm getting maybe 2 hours of on screen time. I have Stamina mode on with a few apps excluded.
[Xperia Z3 Compact General] Brendan12695:
Yesterday I reset my phone in attempts to see if that would help. Today battery life was great until some random point in the day and it went back down to inexcusable battery life especially when this phone is advertised for such great longevity. Not sure what I'm doing wrong. I only have a couple apps installed and have made sure they haven't been running in the background.
[Xperia Z3 Compact General] wingsfortheirsmiles:
After 16hrs I typically still have over 60%:

Went up 1% when I was connecting to put some music onto the SD card, but still pretty good imo.
[Xperia Z3 Compact General] lcohen999:
Thank you for saving me the time of doing it.

I suspect it must be a firmware issue which is causing the drain. If I get 5 hours SOT, I'm lucky. Even at 25% brightness. With the phone on, I can watch the battery drop as I'm doing something as intensive as reading twitter or reddit.

Hopefully, a few fix will be done soon
[Xperia Z3 Compact General] AKZam:
If you think about how stamina mode works, it doesn't let a single app use data if white listed. It keeps your connections open. An app like viber which is always open and online means that effectively you don't have stamina mode on. It doesn't limit certain apps connections, it's all on or all off. It's working as it is supposed to.
[Xperia Z3 Compact General] BLAZEDv3:
I too am having terrible battery life. Better than my previous phones but definitely not close to the advertised remarks regarding battery life. I would take it off the charger around 8am and would be near 25% at 8pm, moderate usage. Hopefully some more charge and drain cycles can help with this.
[Xperia Z3 Compact General] Brendan12695:
Another update, I have now flashed the US software variant as I am on AT&T and wanted to see if it was an issue with signal switching causing drain. Sadly, this was not the answer as it is still draining quite fast.
[Xperia Z3 Compact General] robertkoa:
Yes. Good point about Phone Arena etc.

Are they the ones who ran web script or a Video continually for 9 , or more hours on a charge ?

Problem is streaming a video on 4G , LTE is more

demanding than merely running from internal memory

or WIFI.

Regardless, a lot of people get 6 to 8 hours of SOT in a.single day per charge on this Phone.

Probably easier to get that in one day versus spread out

over 3 days.

And I wonder if fixed brightness on screen is more efficient than auto ?

I don't have one yet probably wait for Nov 3 USA release.

Where are Xperias made, which different countries, anyone know ?
[Xperia Z3 Compact General] BLAZEDv3:
I think they are all made in China.

[Xperia Z3 Compact General] boojay:
After two weeks of outstanding battery life on regular mode with no battery tweaks or tricks, I decided to give Stamina Mode a try to see how much more life I could get and the early returns are pretty disappointing. Without Stamina Mode, I'm getting a full day's use with 7 hrs on screen on average. So far, with Stamina on, I'm on pace to do about the same, so it seems to be doing nothing. In fact, when I check my battery usage stats, Wifi/3G hasn't been regulated at all (it's been on 100% of the time) so I'm wondering if I have a rogue app that's keeping my connection on when the screen is off. Not the end of the world as I'm getting phenomenal life regardless of any power saving modes, but I was expecting some very noticeable gains by switching.
[Xperia Z3 Compact General] Crewville96:
Turn off always on scanning in the wifi advanced menu.
[Xperia Z3 Compact General] boojay:
D'oh! Of course, that makes sense. Kinda defeats the whole point of stamina mode then. You would think they would have automated this, i.e. single click switches off all the necessary features/modes to enter stamina.

---------- Post added at 06:50 PM ---------- Previous post was at 06:31 PM ----------

Well this is interesting. I decided to do a little test. While Stamina Mode doesn't seem to be toggling my Wifi off based on the battery usage graph, it seems to be restricting its use. With Stamina on and my screen off for several minutes, I tried sending some Hangout messages to my phone, but nothing happened. It wasn't until I turned my screen on that the messages came through, so Stamina does seem to be doing its job in that sense. If so, still kind of disappointing because battery life doesn't seem to be boosted despite this. I'll try leaving Stamina on entirely for a day or two before I make a conclusion, but so far I don't see the need to use it if I'm getting the same results with it off, which were impressive to begin with already.

imo stamina mode only extends standby time. sot remains about the same.
[Xperia Z3 Compact General] boojay:
Absolutely, keep in mind though that by extending standby time, I should have more battery leftover for SOT, maybe not a whole lot, but even 30-60 mins more would be huge. I'll test for a while to see if that's the case.

---------- Post added at 08:10 PM ---------- Previous post was at 08:07 PM ----------

One thing that is noticeable so far is that the phone spends less time awake. I'm only seeing wakelocks when the screen is on, which is great. Then again, Sony has done such a great job with the Z3C's power management that even wakelocks with the screen off were minimal without Stamina Mode.

[Xperia Z3 Compact General] rndinit0:
If you look closely, you'll realize the following.

Days: 3

Total screen on time (sot): 7 hours

Avg sot per day: 2.3 hours

My sot hours are 7 per day on a single charge. From 830am to 9pm.

The answer to your question is, this persons 3 day phone usage == my (or yours) one day usage.

In simple terms.

If you both had the same car.

Your Avg number of trips per day require that you fill up your tank once a day. (3 trips)

The other person takes one trip per day, hence only refuels once every 3 days.
[Xperia Z3 Compact General] LadFromWales85:
The Z3c by default has a feature that only allows data access to apps every 5 minutes.

When stamina is on, apps that are in the white list are allowed to wake the phone and access wifi/data subject to the above 5 minute rule. Other apps attempting to wake the phone will fail without error and will act as though they are totally unaware of the restriction once you turn the screen on. This includes apps that want to wake the phone for other purposes, like alarm apps etc.

System apps appear to be able to gain access regardless of stamina or white list, or there is an internal allowed list for stuff like android device recovery and MyXperia etc, as these seem to be able to get through any time.

I believe the system appears as though data and wifi are on despite stamina staying they are off is to avoid apps getting upset at the lack of data and not polling for updates etc due to this.

I have managed 6 hours screen time over 2 days and 7 hours over 1.

I charge daily generally anyway as its better for the battery than dropping it close to zero every other day!
[Xperia Z3 Compact General] Bobb_o:
I've determined that even with my signal booster leaving LTE on will drain my battery because I only get 2 bars or so.
[Xperia Z3 Compact General] boojay:
Sounds legit. While I'm not noticing any appreciable gains with SOT while in Stamina, I have noticed essentially zero wakelocks while it's on, which is fantastic because it's basically a suped up Greenify. Really, just bravo Sony, you did good! Even while on mobile data, my standby drainage is minimal which is really saying something because normally I experience a much greater standby drain (relatively speaking) when I'm on 3g or 4g.
