[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
Bro, you clearly need to reread my original post. Here, let me quote the last sentence for you:

That wasn't me asking for help with my problem. That was me taking a survey of others with the phone. I have read the other suggestions, and replied to several. It wasn't until someone said "wipe your phone" that this went off the rails. I usually use GSAM to figure these types of issues out, but rooting isn't an option thanks to the DRM keys, so I'm stuck trying to resolve this through trial and error.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] techguyone:
Hey Tech support guy, start using those skills. Start by removing apps one at a time to see if something specific is causing the problem, It's well known that some apps can behave... unpredictably with some phones. Mediaserver is usually attributed to Skype malfunctioning, you have a whole list of 'consuming apps' that should be your first port of call.Also try turning bluetooth off unless you're actually using it.

Then come back and report any changes you're having.

A Factory reset should be next on your list, yes I know you 'don't want to' but as you re the only one that seems to have an issue with your battery, it's a good step to take, again on previous phones sometimes a factory reset is all that's needed to make things good again, at the end of the day you want your phone to work like everyone else's seems to, you're going to have to do more than just ***** about it to make that happen. Good luck Tech Support Guy.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
I don't think the consuming apps list is accurate. I'm not even using those apps. I installed and configured them and have rebooted several times since, but I haven't opened any of them. Pushbullet is the only one that may actually be doing something in the background.

And again, you seem to have missed the entire point of my original post. I asked if anyone else was experiencing anything similar. I never posted my screenshots and said "please tell me why my battery is draining". I posted them in response to someone asking for them. It's also pretty far from "*****ing", so I'm not sure where that came from.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
I had some unimpressive battery life as well, when I first started using the phone. I was getting about 4.5 hours screen time with significant drain when not in use. I was able to get that up to over 7 hours with a few minor changes. I haven't used the device enough to say anything definitive, but I'm using a device from UK in USA on T-Mobile in SoCal.

First thing I did was turn off LTE, Bluetooth, and NFC. The signal around here is OK, but not amazing. I'm concerned the signal is flipping around while the phone is asleep between LTE and HSPA+. Honestly, other than uploads, HSPA+ around here pushes 10mbps, which is plenty enough for me. As for the bluetooth, I don't usually drive that much, but I've been on vacation and driving a lot so the car bluetooth music streaming has been several hours a day. As far as NFC goes, I use Google Wallet tap and pay whenever I can, so I just turn it back on while in line to pay.

I also looked at the "Consuming Apps" in the power management section and looked in the Running part of Apps to see how many services they had running. Some were completely unimportant to me, like Twitch push notifications. Not sure if this had a massive impact or not.

I also did some software tweaks. I was using SwiftKey, but now that they are free there's all these ads and **** so I got rid of it and went back to Sony's keyboard, which I actually quite like. I also turned off the Xperia live background. I also uninstalled some unneeded apps. Basically anything that ever had a notification I didn't care about.

That last few culprits I'm trying to weed out:

* Sony's software update frequency

* Audio settings like dynamic normalization

* Dropbox syncing

* Xperia with Twitter / Xperia with Facebook

My plan is to setup a wifi hotspot off my computer as a router and use wireshark or something to see what the phone is doing while "asleep". See if I can figure out what is going on.

I haven't had enough time to really narrow down what the problem really is. Ultimately tho, I suspect there's some OS tweaks Sony needs to make to make NFC, Bluetooth, Location Services, and possibly switching between LTE and HSPA+ more efficient.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
I'm using mine on AT&T and I have noticed that it has been connecting to band 2 (1900mhz) when I'm at work and it gets stuck on that band when I go home, even though band 17 (700mhz) is stronger. I have to manually toggle data off/on to get it to connect to band 17 again.

I'm with you in wondering about the Xperia Twitter and Facebook sync, especially since Twitter is showing up in my consuming apps list.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Bäcker:
So if somebody else has a battery hogging app or setting that is helping you how?

I lose 1-3% over night. With sync on, WiFi on, whatsapp, Mail etc. No Airplane mode. That is not magic but the time consuming search to eliminate the apps and settings draining your battery.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] ghtop:
OK, I get that you don't want any help, but I can't resist asking: why exactly do you think Flipboard or Twitter aren't updating in the background, have you configured them not to? (forgive me if this was already stated but I got a bit lost in all the other comments)

I can't see if you've already tried Stamina mode, but setting it would be a quick way to see (over just a couple of hours of testing) if your battery usage line flattens. That would at least start the process of excluding possible culprits. You can add them one by one to the allowed apps list to see which triggers the problem. It's a shame that KitKat removed most of the useful battery stats :(

Personally, if I were in your situation, at this stage I'd have probably started testing from airplane mode then gradually enabled features and apps in 15 min intervals to isolate the problem, watching the graph closely. But my battery life has been more than good, and most importantly usage is virtually flat when I expect it to be.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
Correct. Flipboard and Twitter are both set to not update in the background. I did try stamina mode. I only excluded email and spotify (so that I could still have music with the screen off) and left it overnight and the battery drain was actually worse, so I'm not sure what happened there.

My battery life isn't horrible. I'm just not getting the spectacular two day battery life that I was seeing in all the reviews and videos about the phone. It's definitely draining a little faster than it should. And if I take it off the charger before bed, I'll lose around 20% by the time I get up, which is extreme at idle.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] CollinsJ:
Given that it sounds like connection issues. Are you connected to wifi that is iffy and it keeps connecting/disconnecting/connecting? Is your cell service iffy where you set the phone? Does the phone get warm, if so it is probably the radio working overtime to get a good connection. My phone is similar to others, I use up about 3% during sleep. I actually use less on wifi than on data, but that is most likely because I never turn my wifi off so it is always "looking". There is a setting that makes it switch to data from wifi if it determines your wifi is slow as well so it may be hopping there.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
Nah, my Wifi is strong. The phone actually charges in the same room as the router and that's also where I leave it off the charger to test idle drain overnight. As for my mobile signal, that is also very strong at home as long as I remember to toggle the mobile data off/on when I get home so it doesn't stick on the wrong band, which has been another weird issue I'm having.

I also have a GS5 and OnePlus One and both have the same apps/services installed and they don't have this issue, so I know it's something with my Z3c, I just can't figure out exactly what the culprit is. It could be one stupid app. You know how an app will perform perfectly fine on one phone, and misbehave on another. The problem is, nothing in my battery stats is pointing me to an app. So, other than uninstalling everything and then installing them back over a long period of time, I'm not sure what else to do. And that would be a long, tedious process.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Bäcker:
install them in groups of i.e. 5

that's quicker and you then would only have to find out which one of the five it is.

could also be google+, chrome or any other Google sync getting stuck
[Xperia Z3 Compact Q&A, Help & Troubleshooting] CollinsJ:
When you get to the uninstall and install one at a time you'll be better off doing the answer you hate, factory reset. Let it run a day before putting anything on to see how it responds. I feel your pain there... would be a non-issue with Titanium Backup.

Are you on build 23.0.A.2.105 in the US? The US stock firmware is still on .93 and I'm wondering if there were some UK only tweaks to the OS.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
This is actually a UK model from Clove. I'm on 23.0.A.2.105.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
I'm doing two things,

First in moving to the US Stock FTF and utilizing an app called better battery stats to track if something is keeping the phone awake during sleep time.

After I reinstall, I'm young to add one account at a time to see what might be the issue. I'm noticing a lot of Google play services requests with Google plus and Gmail etc. So I hope it isn't that.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] ewuzh:
Under Power Management, do you have "Queue background data" turned on? I noticed my battery drained a bit faster than usual with it off. I imagine the more apps you have running, the bigger a difference this will make for you.

Worst battery offender imo while screen off is Google+ i keep unchecking its autosync from the account settings.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] chadmd23:
I've been able to improve my Nexus 5 (I'm possibly in the market for a z3c) battery life by using the GSAM battery monitor. Made it easy to see which apps were really draining the battery with wakelocks, GPS, sensors, etc. Just not sure how far you can get without root, but either way, its a free app and worth a try.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
That's what I'm seeing too. Which is really sad cause I barely use Google+ for anything.

Just an update, I reflashed my Clove UK bought Z3c with the US FTF. I uninstalled a lot of the free apps (evernote, garmin, etc.) and only turned on my Dropbox, Google, and Facebook account. So far, with all the features (bluetooth, location services, LTE, NFC, etc.) idle battery use with Stamina mode on with no allowed apps is very good so far. I should also mention I didn't set up Google+ by opening the app. According to Consuming Apps nothing is using mobile data or wifi while the screen is off.

The first few percent of battery seems to drop faster than the rest, so I'll see how it goes overnight from 95%.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] sdyr08:
Hi dokujaryu,

I too am experiencing the same issue as you. I'm from Australia and bought a Z3C online (posted from Hong Kong). So the firmware is probably not optimised for Australia, even though the D5833 model is correct for my region. When I first bought the phone I was experiencing AWESOME battery performance as advertised. I was flat out using up 40% through a day, 5% at night on standby, and the other 40% the following day. In the last week or so, it's gone to crap. I'm confident it's something do do with a rogue app rather than a firmware issue. I suspect it's google services or location reporting.

It appears I too have had a bit of success this morning by:

+ disabling Google+ and hangouts

+ turning location reporting and google now off

+ turning off device administrators (android device manager and sony enterprise)

+ disabling all location GPS etc

+ran an app called Gservicefix from the play store

Currently sitting at 80% with predicted 22hours estimated battery time reported. This is without stamina mode.

I did a factory reset 2 days ago, but what's the point when all the apps and features I want turned on gave me the same battery drain issues today I was experiencing only 24hours earlier. Especially when Google services and Google+ constantly want to update themselves in the background.

I'll probably turn these features back on, one by one and report back later.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
Are you using a custom launcher? One change in made was using Sony's launcher instead of Nova Launcher.

I'm using Hangouts and Google Voice so I don't think that is the issue. The only account I haven't set up yet is twitter.

I am using stamina mode, but I prefer to use it.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] sdyr08:
Yes,

I'm using NOVA launcher. I was using this since day dot, so I don't believe this is the power bleeding App.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] masands:
Same here. Also Australian firmware and after the first day, the battery life went to ****. I started losing 15% in 9 hours overnight.

I did a reset and did not enable Google Now. Extended Stamina Mode does not even work so I got Green Power to manage Wifi and Mobile Data. That fixed my problem. I'm currently sitting on 3.5 hrs SoT with 48% remaining and plenty of Spotify streaming in Extreme quality .

Looks like the Australian firmware may have some issues with Google Now. You also have to remember that Telstra cancelled/delayed the Z3 and Z3c launch because some issues with the firmware.

Disabling Sony enterprise really did it for me. ~10% improvement.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
Quick update before the phone dies. I got over 8 hours of screen time and almost 11 hours of use (screen + calls + Bluetooth music etc.)

[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
So, I was able to get over 11 hours of use out of the phone including strenuous screen off usage like music over bluetooth and phone calls. Stamina mode was on the whole time with no authorized background apps. The usage broke down about like this:

~1.5 hours of phone calls

~.5 hours Google Maps navigation over bluetooth with music streaming @ 100% brightness

~1 hour of music streaming with no navigation

~8 hours of web browsing, email, reddit/imgur apps, etc. @ 1% - 50% brightness (night time vs. day time)

~12 pictures taken

Overall, that's better performance that I need. I'm doing another test now with Stamina mode off to see if I get a solid ~4 hour screen time day out of it at max performance.

The only difference between now and when I was getting poor battery life are:

- US Customization FTF

- using Sony Launcher instead of Nova Launcher

- No authorized apps in Stamina mode (before I authorized Hangouts and Facebook Messenger)

- Sony keyboard instead of Swype

So far, I think maybe the US customizations is what did it? Nothing else really makes any sense. Maybe it's contacting the UK servers for something from the US?

You can get the US FTF from here: http://xdaforums.com/showpost.php?p=55796043&postcount=18

[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
I wonder if maybe it has to do with different radio optimization. My issue with stamina mode with nothing allowed is that I have apps I need notifications for (like email). That almost makes it a feature phone when the screen is off. I had the same experience as you, though. When I allowed anything, everything seemed to get through.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
Oh that wasn't my experience at all. I only allowed Hangouts and messenger, and that's all that for through. But it still drained battery very quickly. I think there might be some kind of optimizations in the launcher, or just the US customizations. Either way, if seems like it don't even need stamina mode now.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
Sorry, I thought it was you who said that. When I had mine in stamina mode, I only allowed Email and Whatsapp and all of my notifications were coming through. It was weird.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] dokujaryu:
Did you have the option checked to not come out of stamina made when checking the time? It will allow everything through on the lock screen unless you check this option.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] greyhulk:
Nah, it wasn't that. The phone was still receiving all notifications all the time with the screen OFF. It would just be sitting on the table and Facebook, Hangouts, etc. would trigger the LED and notification sound. When I turned it on, it was notifications for apps that weren't allowed. I may give it another try, though. I just found that my battery was actually worse with it on.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] NYC_ROCK:

I am still only achieving 16-20 hours a day, with up 25% Cell Standby and 18% Phone idle.

Last night, once charged to 100%, I took it off the charger. It went down to 75% within 6 hours in idle (4-5% per hour) - just sitting on my beside table. The signal bar graph shows 'green' so I apparently live near a tower and signal is great.

I am now suspecting a damaged or defective sim card. I had to cut this sim card down from a micro to a nano sim card.

I have ordered a replacement sim card from my provider and will report back.

Some googling on the internet shows other people have had similar issues...

hey,

discovered this thread this morning while sitting in train. later i was looking for settings i could turn off to improve battery usage. i didn't find a lot, but seems like disabling 'settings' > 'about phone' > 'usage info settings' (send anonymous data and usage statistics to sony) did the trick for me.

with regular occasional usage and some phone calls the battery only went down by 12% in the last 8,5 hours.

Hmm..I'm very tempted to try this, as I'm also on the latest UK firmware (my phone came from Clove), but I'm located in Canada.

I noticed that overnight (~7 hrs), the battery drained about 11% (from 29% to 18%) when it was doing nothing, and I had the cell radio shut off so it wouldn't try to search for cell towers if it ever lost connection. I then tried changing location reporting from "High Accuracy" to "Battery Saving", and this time it dropped 8% (from 100% to 92%) overnight, so an improvement, but only marginal. When I checked in the morning what had used battery, Phone Idle was at 32%, while Google Play Services was at 14%..I think Google Play Services might be just the syncing of all accounts set up on the phone?

Phone Idle may be due to the firmware being UK as you have mentioned above dokujaryu, and it searching for something on UK servers..? Do you have any further updates as to your battery life after flashing the US firmware?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] CollinsJ:
I'm in the US, never reflashed firmware after my Clove purchase. My phone uses about 2% batter over my sleep cycle, probably closer to 1% but once in a while I notice 2% most likely due to where it is in the percentage cycle when I set it aside for the night.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] mat_oli:
wow, that is amazing! How many hours do you sleep for?

And what is using your battery during that time (even tho it's just 1 or 2%, I'm still curious as to what is actually consuming battery).

Are you connected to a wi-fi network overnight? Do you turn off the cell radio overnight as well? Do you have auto-sync enabled?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] CollinsJ:
Bout 6-8 hours, I never turn off wifi, bluetooth, cell radio or turn off auto-sync. Connected to wifi. So figure 6 hours about 1% it would take roughly 500 hours to use battery, figure that is decent standby time. Oh and tasker sends a couple texts while I sleep as well as using the phone as my alarm clock.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] mat_oli:
Wow..that is amazing standby battery life. Do you have stamina/ultra-stamina mode enabled?

I'm tempted to wipe my phone and slowly install apps 1 by 1 to figure out what's draining my battery so much faster than yours.
