Damn were you always connected to WiFi or do you use LTE or 3G? Follow us with your secrets :D

I have installed these Chinese apps like Taobao TMall which kinda always on and bit drains the battery.

Yet I don't complain cause I get about 5-6 hours of SOT and about a day of usage. :D
[Xperia Z2 General] Pesetio:
You have good battery life if your always using it.

I just used it moderately and that screenshot is misleading,I would say it was more like 8 1/2 to 9 SOT, if the screen timeout was at my usual 15 secs.

I was just testing to see the battery life since my phone seemed to be hot before but now I got a cold cycle so my phone doesn't run hot anymore. Seemed to make quite a difference.

And yes I had Wi-Fi on and no mobile data.

I don't think it should let's see.

[Xperia Z2 General] Don MC:
It will consume more battery because the digitizer will stay on and react to every touch. When it senses a double tap, it will wake the rest of the device.
[Xperia Z2 General] edge3uk:
I've had 7 hours of screen on with tap to wake turned on. I have a lot of apps installed and use it for alsorts. If it does use more power, it's completely negligible.

On which firmware mate?
[Xperia Z2 General] edge3uk:
Sorry. 55 firmware. New one hasn't hit UK yet.
[Xperia Z2 General] BR4DOKYBrazil:
I think so too! For the digitalizer stay on all the time should be battery consumption, but if there was a large consumption, Sony put a warning before you activate it!

FW .402 is consuming more battery than the .55 and .69! Someone also noticed?

Hey can anyone here please post a screenshot of their power management screen? Like the stamina mode/low battery mode screen. I have a feeling I've either got a dodgy sensor or something is definitely wrong. My phone is giving me ~2 days standby estimates at 100% charge even on airplane mode with stamina and low battery mode on. I've tried to clear data on eco mode controller in apps to no avail.

If anyone here has more than ~2days estimate on standby at 100% charge, I'll be returning the phone :) thanks in advance!
[Xperia Z2 General] vlawrence0324:
Here's mine

---------- Post added at 06:17 AM ---------- Previous post was at 06:15 AM ----------

I think it would be best to compare the estimated time left if the percentage is at 100%. I'll be charging my phone and let you know if I have more than 2 days estimated time
[Xperia Z2 General] Devzz:
Thanks! Could you possibly tell me what it was at over 80% charge? I've got 95% at the moment and it still says ~2 days.

Edit: Yeah I clarified my earlier post lol thanks for that!
[Xperia Z2 General] stephen2529:
Hi guys

Think I've got a similar problem to the guys above. On a full charge my estimate is only about 5 hours on time. With all stamina mode ect on I get about 1 day 4 hours. My friends both get much higher estimates than this. Like 2-3 days. It's there something wrong with mine

? I've owned it about a week now so I'd expect it should be accurate.
[Xperia Z2 General] Devzz:
Hey, I'm just on my way to get it exchanged now! I have a feeling its a sensor problem as my last Z2 had a defective headphone jack and a lot of hardware problems are reported online. I've got this whole thread as proof and the official Sony developers blog site thing has screenshots with estimated standby times on that so I can't imagine they'll argue about it. Will update in 20 minutes :) I'll also be making sure this time the new one works as it is meant to!

Edit1: Have to go to a different branch because the tech here isn't available! Update in an hour :(

Edit2: Perfectly fine now! Think it was a hardware issue so anyone with a dodgy battery sensor should be okay to change it. Unfortunately a tech was not available at any of the stores but the rep saw all your screenshots and the one from the Sony page on Power Management and just changed it for me! :) Extremely pleased with carphone warehouse and the phone now!

Battery Graph

For some reason, GSam Battery Monitor Pro did not tally with the phones stats exactly. I think it was because I didn't install the Kitkat battery stats thing it asked me to or maybe its because i'm not rooted. Don't know really. Anyways, it's only off by about 1 or 2 minutes and still as credible, you get a better idea of how i used my phone. :)

Here's mine. Yes, it's real and not Photoshopped. It was active but mostly on standby (with wifi), but I only used it minimally (a few phone calls, some photos, about 2 hours of music with noise-cancelling headphones, minimal internet,/Snapchat/Vine).

Awesome phone! (now it's time to charge it)

Except sound. Sound should be better.... My opinion tho
[Xperia Z2 General] Devzz:
I'm about to make you very happy then! Here's what I did just yesterday, as up until then even this new phone reported the same wrong estimates.Firstly check what firmware number you're on (.55, .69 or .402) and what country's firmware (are you with UK generic like I was or the Taiwan/German Generic?). Make a note of this and now go to your 'all apps' list. Clear the data of the Eco Mode controller, power off your phone, wait 30 seconds and reboot. Go to power management and note the time it states for estimated standby and then set up stamina again. It should work! Last night I got 8 days estimated standby on the German generic .402 firmware!

If there is no difference then flash the German/Taiwan generic .402 firmware and redo the steps. Keep notes as you go along and then update us please as the UK .402 FTF file isn't out. As far as I know, any generic .402 solve this issue as these steps did not work on .55 for me. However if they do work for you on .55 then I obviously did something wrong and anyone else reading this (and is on .55) should just redo the data clearing steps again.

Hope this helps!

I'm still on . 55 at the moment. So far resisted the temptation to root this phone.

I gave this a go just now and battery estimate went from 1 day to 5 days 3 hours on a 96% charge.

That seems much more like it. Let's see if it stays like that.

All I have is extended stand by mode control, is that the same thing?
[Xperia Z2 General] Haldi4803:
i have to say... not bad!

About 3-4 hours of this SoT was with 100% Brightness in MXplayer and vGet in the background (that app is a huge battery hog!) No battery saving features.

But the Standby surely is nice. though i'd rather call it "not really using the phone" than standby... about 10 minutes phone call, lots of whatsapp/telegram some facebook and 1-2hours of Tapatalk.

From these 40 mins wakelock in 22hours 17 minutes are by Partial wakelocks and 5 minutes by phone call.

Partial Wakelocks are mainly listening to Music with speakers.

even tough there are quite some alarms i can't say which of them are bad for battery and which are necesary for a working phone ^^

Compared to my old Xperia Z, with roughly the same usage pattern, over 30+hours i'd get about 1-2h SoT :laugh:

And now i'm on 2% and can't flash doomkernel v8 -.-

Quick question

Why is it in battery stats there is always a solid blue line under wifi even if wifi is off all day?
[Xperia Z2 General] Haldi4803:
there are 3 types of Wifi.

Wifi On, WiFi running, WiFi connected!

Even if it's not Connected it can be running, and even if it's not running it can be turned on !
[Xperia Z2 General] stephen2529:
Oh right I see. So I'm assuming it's out of our hands then? No way to town it off properly when not in use?
[Xperia Z2 General] vlawrence0324:
Under power management turn on location based wifi then set policy to advanced. It will turn off wifi when you are not near in any saved wifi networks.
[Xperia Z2 General] Devzz:
For some reason Android OS keeps my phone awake ~26% of the time (3h 46m). Does anyone know what could be causing this? I am not rooted so I cannot use wakelock detector and I have a lot of apps that came with the phone disabled. Auto sync is turned off too.

I've been underclocking with a peformance governor @ 1196 for quite a while now, battery is much better now since I have done that.

I get over 4 days and over 6 hours on screen time with light to moderate use. The battery drain in Youtube ranges from 1% per 5-8mins which was 9.8% per hour.

GPU is set at 200Mhz

Phone is set to use a conservative governor

I use "Per App" to set most of my apps to run @ 1196 on a performance govenor, some apps run @ 300 like flappy bird, minecraft runs fine @ 1196 in survival mode with the default graphic options, no lag.

Launcher is set to run @ 1196 as well.

The advantage of a performance governor is that it gets into deepsleep very quickly.

My phone never gets hot at all, only when I did 4K for 18mins which didn't crash,received a phone call which stopped the recording.
[Xperia Z2 General] iArvee:
How come WIFI shows that it's always on when I turn it off? :/ Power policy is set on Advanced. I did a test earlier and the wifi did turn off, but it still shows as on under the battery usage.

Just to clarify: I assume that the wifi turns off because the phone was out of the saved location. Upon returning to the location, the wifi did not turn on again. So I'll have to turn the wifi on again manually? Is this correct?

So, every now and then I'm having issues with my phone being kept awake and it was suggested by another forum member to install BetterBatteryStats which I did, now that the phone has decided to stay awake while BetterBatteryStats is logging things down, it's telling me that the partial wakelock that is stopping the phone entering deepsleep is "handleMediaEvent" what should I do to stop this occurring?
[Xperia Z2 General] se1000:
Your physical battery shouldn't degrade that fast. It's almost always a new app or an update to an app that causes wakelocks that make it seem like battery life gets worse quicker than the battery is actually getting worse.

I never toggle WiFi, it's always on same with bluetooth. It happens almost always after having used my phone in the car with bluetooth to play music from (I use my phone as the source of music connected to the car stereo via bluetooth) but sometimes it doesn't stay awake after leaving the car. Also the phone stays awake randomly too like this instance so when it hasn't even been near the car stereo, I restarted my phone this morning after taking it off charge, I've had 1 text message and 1 snapchat message and I've used the camera for a couple of photos and nothing more.

Battery discharged from 98% to 8% delivering 7 hrs of SOT with moderate usage (1.5 hrs of 3g calls, mixed wifi & 3g data browsing via chrome, camera use, hd videos playback, music, emails etc.) and few hrs shy of 2 days standby. It runs on stock (non-rooted) rom. Stamina mode was never on, only low battery mode enabled. Screen brightness set at auto with about an hour of usage directly under the sun. Well, with such battery performance by Z2, I'm happy to say the least :victory:!
