Holy **** dude! For kicks I tried toggling network mode to WCDMA only (I only have HSPA+, no LTE) and my already impressive battery life has increased DRAMATICALLY. At least, early returns seem to be that way.

Thanks for the tip!

[Xperia Z3 Compact Q&A, Help & Troubleshooting] leventbb:
I also had short battery life problem recently and I think I managed to fix the issue, thanks to everyone sending tips in.

Firstly, I'm fully stock, no root etc and have the latest 77 rom on a D5833. I have autosync, Wifi, 3G on all the time. BT and Location on when needed. NFC is off.

I have facebook, twitter installed but notifications closed and have whatsapp running all the time.

I had around 35 hours of standby with 3 hours screen time during problematic time. Using Wakelock Detector's amazing PC version ( that does not require root and can pull battery stats out of the phone like rooted version) I saw two big issues with my usage that triggered wakelocks. The big one was handleMediaEvent which once fired up will always remain active and keep phone awake. Since I do not listen to music on the phone, I was surprized and tried to pinpoint the time it was launched, turns out it was my car's bluetooth system that launches it and even after I leave the car and shutdown bluetooth it remains active in the background. So I'll try to find a solution to the problem, but locating it is important enough for now. I'll try to update my car's firmware and work on bluetooth settings to disable music and related wakelock.

The other big battery eater was google+ app. Although I do not use the app, there is no way of uninstalling it (without root) and noticed that it re-enables itself after I manually disabled it. It was either twitter or 9gag apps that I use frequently, triggering google+ to remain in the background. I uninstalled updates of google+ and set auto-update disabled in play store app and then disabled it.

My idle battery life is much better now. I have 61% battery left on 23rd hour with 2h screen time. I still think the battery life is not amazing as some people report, but as said earlier, it depends on usage a lot.

I really advise people to check their usage details with Wakelock Detector to get a clearer picture of what's going on with the unit.

red rectangle shows awake time, without going into screen view. if its a flat blue line, something is keeping phone awake.

Well I'm kinda seeing the same thing on my Z3C. I'm on airplane mode and "phone idle" is my second biggest consumer (24%) next to display (35%), way above any Android OS or Play Services, which I find really strange!

On the battery usage graph, there is absolutely no usage over night, however the battery drain was at ~20%.......

Did you find a solution to this stupid problem?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] aviduser:
Some tips I tried.

Initially when I brought the phone I had terrible battery drain. I traced it to the SMART CONNECT feature. I turned this off and use Llama instead for the same functionality.

Secondly at home my 4G connection was terrible, changed the phone to #G only and now have FULL signal bars at home and phone Idle drain is much less.

If I need 4G out of the house I just toggle it on.

Also use stamina mode and enable Facebook Talon Reddit Whatapp messenger etc. Always have FULL SYNC on all accounts including business.

Have been really happy with battery once discovered the Smart connect bug. Note recently smart connect was upgraded with bug fixes so not tried it recently.

LOVE THIS PHONE, except I scratched the rear glass a little bit.

Dear Sony please improve camera software and I will buy your 4C 5C etc keep this up I will stay brand loyal for years and EVANGELISE your products!

[Xperia Z3 Compact Q&A, Help & Troubleshooting] Lazer72:
I updated to the latest firmware. Xxxxx5.77. And I've been experiencing severe battery drain. Only when using it though, I can visibly watch the percentages go down right in front of me! I can lose 20% In less than an hour!

I've tried factory reset. Even flashed older stock firmwares (no root required). No joy.

Standby time is still pretty cool. Overnight I lose about 7%. I keep everything off except data and sync.

Please help.

Hi guys, just wanted to share a possible solution.

I had the following issues, especially after the phone is rebooted:

The phone would get unusually hot, plus battery drain

Google Play won't download any apps

The Ringtone sound picker won't open

Some parts of the Settings are unresponsive.

My solution was, low and behold: Turning the NFC toggle on.

It seems like when the phone is restarted it looks for NFC. If it doesn't find it, it'd just keep looking and hog all other resources.

Let me know if this is true for anyone else.

--------------------

Edit: the above seem to only work once for me. No longer works :(. Anyway, is anyone else experiencing the same issues listed above, along with the battery drain?

I've been having the same problem as you. First of all I'd like to say I haven't found any solution for this, but I have some information that may be useful. After several tests trying to fix this problem I found out, that the problem is only present while using the phone (screen on), and that the drain is much higher when you have your phone radio on, whether you have a good signal on any network type (LTE, 3G, etc.) or a bad one. I also have tried several things as changing most of my settings, resetting my device to factory settings, using it in safe mode , installing different firmwares (D5803_23.0.1.A.5.77_US.ftf, D5803_23.0.1.A.5.77_RU.ftf, D5803_23.0.A.2.93_GEL_1290-6916.ftf) and even having it changed for a new one with the company I bought it to, having no success. If anyone has found a solution or has some useful information on the topic I'd be very grateful if you shared it with us. (Sorry for my bad English)

I have the same problem, install Gsam battery monitor and see what app takes the most battery.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] Nick ZA:
Hi Guys

A see a lot of people having battery drains, although what it looks like to me is that most peoples problems are app related. There also seems to be a bug regarding the wifi & mobile data antennas

My battery life seems to chop and change between being steller and being average, I never really have bad battery life.

On a good day I get around 4hrs -5hrs screen on time and a full days usage with around 50% remaining by the evening, which to me is incredible.

But when I'm at home my battery disappears much faster, which is when I'm connected to wifi. It seems that the "cell standby" and "phone idle" %'s increase drastically when I'm connected to a wifi network, I'm not sure if anyone is experiencing similar? It appears to be a bug when connected to a wifi network that the cell antenna drains much more battery, well at least in my instance.

Under "Advanced Wifi Options" there is a "wifi optimisation" option, which I have just found, I will try it out when I get home and I am connected to wifi and report back. Perhaps something for others to try and report back too!
[Xperia Z3 Compact Q&A, Help & Troubleshooting] monsieur_debile:
For instance, i have lower drain at idle than most of yours since i really care about settings and attempt to understand Android and Z3 Compact

Drain constantly increases if you use much your phone by every couple minutes (time of awake will increase, deepsleep will on the contrary lower)

Stamina mode isnt a magic mode which allows every user to stop phone draining completely

It varies from your settings, apps and type of use, your location (if your under a good 3/4G coverage)...

About loss at idle, if stamina and setting correctly set, if you still meeting a drain issue, wifi/3/4G might be like mostly the usual suspect

Some apps forced and constantly wake the system up (alarm) every x minutes through wifi/data mobile

A bad provider and under bad 3/4G coverage, you will experiencing a bad mobile phone signal, it may increases/create the related wakelocks

Some providers have roaming in their contract with others providers, it means, x minutes/hours, system will check and attempt to catch newer signal (from roaming process, it about switching from provider antenna 1 to another provider antenna), you will get a radio-interface wakelocks, which means you phone wont actually go into sleep mode (most severe battery life drain at idle i ever experienced)

Note wifi has nothing to do with this wakelock
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Woodruff226:
I've a Z3 compact for 6 weeks now. At first the battery lasts for 3 days Until last week.

At first it drains a full battery by 60% overnight.

In the daytime the Z3 was feeling warm and still a huge battery drain.

By reading this forum I saw a similar situation. Last week I was using (once for try out) a bluetooth headset.

After disconneting the bluetooth headset (Imperial Blutc) from the phon.e, . I shut down the Phone and did a fully recharge.

That was yesterday at 14:55. Today at 17:50 it's still on 84%.

No, I'm not a heavy phone user, so it should last at least 2 days.

Battery life and specs were the reason I choose this phone.

My settings:

wifi on location = on

bluetooth for carkit = on

no stamina

google ads = off

google location = off

backup = off

Sadly after a few days later I experienced another battery drain. The phone now lasts almost a day. The only thing I could think off, was using the Google mail app. I did twice taken some photos and email them. The first time was short before my first huge battery drain, the second 2 days ago. I will post my fidings.

I have the same problem

I got the drain problem, so i did a factory reset and it worked, i got the wonderful batterytime again, but then today after a week its back :S

i have 8 hours battery on 99% charge without stamina and 22 hours with stamina active.

i can add screenshot but i have looked in to the app list and its nothing abnormal there and i looked in to active apps and i even tried to uninstall apps and change to only gsm mode without success.

I dont want to do a factory reset every week to maintain the awesome battery life, but something must be wrong, i didnt install any app or did anything, i got to sleep and the battery time was good and in the morning when i took the charger out the drain started :S

any ideas??
[Xperia Z3 Compact Q&A, Help & Troubleshooting] qbson17:
I have got similar problem as You guys. My guess is that something is wrong with one of the preinstalled android apps like file commander, gmail or chrome. I've installed wakelock detector and it doesn't show any disturbing wakelocks while the battery is still drained. I've got also another problem that can be connected with it. Sometimes while browsing internet on wifi telephone is getting warm. So maybe Chrome has any mistakes.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] david_diesel:
Same issue here...

With data or wifi enabled, i lose a percent every 2 minutes when i use my phone (just a bit of texting or writing an email for instance). The drain is of course more important with 2/3/4G.

FYI, when i don't use the phone at all:

i lose around 1-2 percent every hour with Wifi on. When wifi is off, i only lose a percent after 8 hours.

I agree with the previous post, there has to be an app draining the battery.

I uninstalled File commander, so it's not it.

Maybe Chrome? I always greenify it when i don't need it but it keeps popping up.

Maybe Play Store? Same thing, i greenify it but it keeps popping up.

EDIT: i always am in "Stamina" mode

battery drain

same here, was getting 3 days battery, 3-4 hrs screen time, 2-3 hours of calls with just that one charge, now phone won't last2 days, with 1hr screen time, and 10min calls, must be an app that has been recently updated. frustrating.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] qbson17:
Its hard to figure out what is triggering drain. Now my phone has wifi turned on and I used Chrome for 15 minutes and the battery is ok. There is no draining. So it also cant be Chrome and wifi itself.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] mat_oli:
how did you guys install wakelock detector? are you rooted?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Xisiqomelir:
The update screwed me over in a tonne of ways, not just battery, so I downgraded to a 93 FW (Global - Promoter from xperiferm).

By tonne of ways, I mean that updates stopped working, I'd get random hangs, the screen became unresponsive etc. The drain also sucked. I left it alone at 93% at 11:30 pm and woke up at 7 am and it had fallen to 15%.

Things are cool again after the downgrade though. I hope the Lollipop update works out okay, but I've learned my lesson about trying Sony's sw out before other victi...people.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] mat_oli:
I got the PC version of wakelock detector working, and what I've noticed so far is that "media" is usually at the top of my list, at 30%+ usually. I'll try to take a screenshot later, but anybody know what this is exactly?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Merwyn:
I'm also having some problems since a few weeks with the battery life, especially at nights : I'm always putting my phone in Airplane mode when going to bed and it used to consume 1-2% max over night, but now it's more like 6-8% and what's more when I'm using it, the battery isn't as great as it was at first (2-3 months ago).

I was able to get over weekend without charging if I weren't playing any game, but now it's over : I have to charge it every evening, which piss me off since I switched phone because of battery life and on my old phone, it was loosing only 2-3% overnight and had a weaker battery...

Now if I'm playing during the day, I'll have to charge it on the afternoon, pretty annoying.

Here are a couple of screens of it discharging over night, in case it helps. :cowboy:

To sum up what I did :

I had normal phone, it worked great. Installed lot of stuff and all, was happy, got a nice flip case, a nice charging station and all.

Then the battery became bad, I though heck, let's factory reset since it's often said it may solve the problems.

While I was at it, I rooted, because I didn't want to waste a factory reset and all my time for nothing.

Now I've a rooted phone, but the factory reset didn't help, so it must be something else. :eek:

I tried with Better Battery Stats, which was great to help with battery problems on my old S2 at the early days of the S2, but I wasn't able to find anything useful which may explains the drain over night. See the screenshots I've attached.

Any clue ?
