I play mostly Marvel Puzzle Quest and I get 1.5 days with it. But my SOT is only 3 hrs plus. I haven't tested my SOT when I'm not playing any games but I think 4+ hours is my max. I noticed that Calls eat more battery life than Marvel PQ so it's a little weird.
[Xperia Z2 General] ghostofcain:
Are you in an area of below average reception? Continually swapping radios 4g/3g/2g is going to kill battery life.
[Xperia Z2 General] edge3uk:
I use mine a lot. Bits of everything except heavy gaming and 4-6 hours is normal over a day, with GPS and smartband in a crappy signal area is normal, whereas itll do 8 hours on WiFi. No stamina. It goes down to expectations. I never get more than a day, just most days I'm signing off with 30-40% remaining.

Typical whiner. When **** happens to not work out for you, first thing you had to do was spending a minute at finding fault on others by claiming that its "impossible" to have such SoT, cool. Sorry for you that your battery sucked a big time :cool:

If you want to hit high amount of SoT, simple. Just remember few ****:

Phone Signal, Background process (specifically, wakelocks; a reminder: just cause you greenify every apps it does not justify your wakelocks (not all the time apps causing wakelocks), DO your research extensively) and settings.

In some cases, depending on application that you use can affect your SoT. For example: streaming videos on Chrome browser consumes much less battery comparing to Dolphin Browser.

Also, if you think you have applied all the necessary battery tips and yet you can't achieve what others did. Grats, you have just purchased a less quality unit from Sony. :good:

Anybody facing battery drain problem with newest update - 314?
[Xperia Z2 General] Haldi4803:
So I went to this Open-air in Benesov on the way to I activated flight mode. Watching videos and reading comics on lowest brightness Auto, in the car.

5hours and 47% so 10hours SoT are definitely possible without 3g drain.

And then the way back with mobile data offline but network connection.

I already used it during the open air to take some videos and Fotos.

And back to 3g when back home.
[Xperia Z2 General] goodpenguin:
There is that possibility. My cell standby is around 9%, same with Android OS. But I'm not complaining since this is way better than my last SGS2. It's possible I can get 5 hours without playing any games.
[Xperia Z2 General] stanley08:
Try a factory reset or if you are rooted, use Better Battery Stats (http://xdaforums.com/showthread.php?t=1179809) to find culprit, if it's an app.

Different people use their phones differently. As for me, i have never gotten below 10 hrs of screen time. Believe it or not.

[Xperia Z2 General] stanley08:
Everything works well here. I did full wipe and used flashtool to flash it, because I was coming from CM. Maybe it's an app draining ur battery? Btw dude! EPIC Username mate! El Guaje! :)
[Xperia Z2 General] antti91:
So these are my stats for the last full charge. Stamina mode active below 50%. What do you guys think?

Would it be worth rooting in order to get Greenify with all its settings? I have also heard about a module for Exposed that can turn on 2g network while screen is off. Anyone who knows more about this...

Haven't really been into rooting and modding since the good old times with my Galaxy S I9000 and thought that it wouldn't really feel necessary with the Z2. Maybe I'll have to reconsider.

Yes I did full wipe. I tried different 314 ROM but the result is the same.

I flash again 314 and did not install anything except Facebook app, Messenger app, 9gag app and use it for a day. Battery drain still persist.

I rolled back to 402 and everything work well. I noticed that in 314, when you're changing your phone, it get really hot (40 degree celsius) compare to 34 to 35 degree in 402 (same condition).

Yeah! That's my number 1 favorite player !!! :highfive:

And yours? Stanley? Let me guess, in swordfish movie? :D

After I update to latest 314, my battery is draining a lot lot faster than it was on 402.

on 402 I used to get full 3 days with my phone in stamina mode, now I get only 1 day! exact same settings regarding power management.

using Wakelock Detector I found something strange:

PowerManagerService.Display : 45m kernel time,

PowerManagerService.WakeLocks : 46m kernel time

I will try disabling Tap-to-Wake feature to see if it improves.

DeepSleep acc. CPUStats and BetterBatteryStats = 96%
[Xperia Z2 General] Haldi4803:
Yeah, I'm not that fond of 314 either!

But that might be because I'm listening to a lot of music lately, that drains the battery extremely fast -.-

Android OS keepawake

Hey,

I've been noticing a massive spike in the kernel's (Android OS) battery usage in the last few days. It's had keep awake times of >10 hours!

I can't figure out WTF is going on, I already tried factory resetting.

I'm rooted and running some Xposed modules, but disabling xposed didn't help.

Anyone have any ideas?

7 hours is pretty much standard for Z2. I easily get that. With Stamina mode you can go double.
[Xperia Z2 General] Abby Oddie:
Z2 Battery life is actually pretty good. This was a big deciding factor for me. When in a real jam, you can easily swap out the battery with a backup. The battery is small enough to deem it practical to carry the spare around in your pocket, but more realistically you would keep the backup in your laptop bag/purse/satchel. This can effectively double the up time for your phone if you plan accordingly. There's a battery case/charger available for $50 that you can get that makes this really simple. Plus, when you register your S5, samsung gives you 50% off up to 5 accessories.
[Xperia Z2 General] ghostofcain:
Seems some confusion here, Z2 battery isn't removable, and then your talking about S5 which is Samsung.
[Xperia Z2 General] antti91:
Seems like you are posting in the wrong thread... Or trying to promote the S5 in a not so subtle way.

OnT, does anyone know why according to GSAM, Android system uses the most battery of all my apps, and here comes the strange thing. Passpoint seems to be using the most battery among system apps, and if I understood correctly passpoint is something WiFi related and I have it deactivated in WiFi settings... Any ideas?

Samsung Galaxy S I9000

Install better battery stats and have a look at what's keeping your phone awake, you should expect a SOT of over 6 hours.

My battery life from yesterday.

14h battery life with 11h of screen on time.

My settings:

Minimum brightness as much as possible, only on auto when outside

Xreality off (don't like how it oversatured colors)

All music enhancement off (il like to listen to my music as it was meant to be by the creator :P plus it reduce power consumption! Double win hehehe)

Stamina with restricted performance when battery reach 40% (i'll explain what this setting do and how I use it later on my post)

And no custom rom or kernel, all stock with the last 314.

My use from yesterday

40min of call

4h of video playback (on streaming, with youtube and other apps)

Whatsapp and viber all day long

A couple of photo with 8mp manual mod

And internet browsing,fcbk,twitter etc all the rest of the time.

So... THIS PHONE ROCKSSSSS

Usually I get most of the time at least 8-9h of SOT time with 18-24h battery life, and I am a heavy user.

When I play game's like injustice or real racing I just activate restricted performance (under stamina settings), on this mod CPU governor change to a more conservative on and framerate is limited at 45fps (this is more than enough for a mobile game) and this prevent the phone from overheating!!

I also do that when I watch movies (movies and videos are at 24fps so you won't see any stutters or lags, and this with xreality off really improve power consumption, I lost barely 5-6% on 1h of streaming video!!)

I think that with this kind of battery life no need to mod or unlock this phone

hope I can help people getting a better battery life by sharing my founds and my settings and sorry for my english
[Xperia Z2 General] Haldi4803:
Mostly Standby!
[Xperia Z2 General] dryspuri:
What is restricted performance! where do i find it in setting, I cant seem to find one, can you do screenshot please
[Xperia Z2 General] angel_salam:
In settings, go under "power management", click on stamina, scroll down and click on "restricted performance" (I don't know the exact translation because mine is in french)

When this mod is selected to reduce power usage it use a more conservative cpu governor et limit screen framerate to 45fps (perfect for gaming and watch some videos without heat and battery drain!)

Ps: when you select that mod your have to turn off you screen and turn it back on to take effect! Hope this may help you.

I don't know how to post screenshots here :/

Sorry for my english

Believe me , when it's come to battery .. M8 is the best

Don't care for what gsmarena says or some other website, because of the 3200 mAh

HTC has something insane with "Battery usage" Of course it's just a 2600mAh But see what can it does

Full day with a really heavy usage

Power saver is ON & auto brightness & stock kernel
[Xperia Z2 General] beni8978:
I doubt this is true and if it is you probably are rooted and some tweaks(maybe custom kernel)+ fully lowered auto brightness.

Because I see that your HTC battery friends can barely make 6h screen on.

So this are my battery stats,full brightness,fully stock,no root nothing.

P.S.

Not one mobile device can beat the Z2 in battery life right now.??
[Xperia Z2 General] Jiyeon90:
That's a huge lie, my friend had a m8 and since he is a heavy user the battery wouldn't last him 1 day, he got rid of the m8 and got a Z2 and now battery life is the least of his worries

I'm checking out these forums as i'm looking to a Z3, but had to reply to this. The LG G2 is the proven battery king right now, but besides that, M8 does indeed outlast the Z2, there's plenty of proof around.

Only thing with Xperia's is the compromises you always have to make, with the Z and Z1 it was almost everything, screen, camera, speakers, call quality, low music volume, with the Z2 it seems they've improved on everything but with a 3200 battery the battery life should be 10 hrs screen on at least.
[Xperia Z2 General] chesterr:
Are you having auto-sync on and gps on? BTW Will you please share your settings and all?

Almost every one knows how good is the " htc sense " and how good battery it gives

And I always get about 8h screen on time with almost full day with no charging

"

WITHOUT POWER SAVING MODE

"

check this out

I almost get the same result ..

And when I turn the power saver on , It gives me over 10H SOT ..

.. if you still can not trust me , try the m8 sometime with your normal usage like the z2 and I'm sure that you will have a great experience ..

Thank you and sorry for bothering you
[Xperia Z2 General] beni8978:
I forgot that you have extreme powersaving mode...so with that you can get 5+ screen on easily
[Xperia Z2 General] sfex3best:
dude I got 12 hour 15min sot with the z2 streaming videos online and a bit of whatsapp. Lowest brightness and stamina mode on. no hacks stock Rom. I posted it a while back.

I've also seen someone with 14 hours sot on the z2 in this thread.

Also the z2 doesn't have 3200mah battery it includes 3392mah battery to be exact.
[Xperia Z2 General] Jiyeon90:
Compared to other phones those are good results, but compared to the Z2 not really.

Yeah it's a lie..

Unless you can achieve 1 day of usage with ~5h SOT and 60% of battery left like I did.

[Xperia Z2 General] sudisk:
Calm down people!

This thread is about Z2 battery performance, and ways to improve it. I don't doubt that it must be possible to get more than 10h SoT with the M8, but I personally have no interest in that device and would rather have positive insights of how to make the best of my Z2 battery rather than compare it to another device.

With my usage and my network availability conditions, I have never been able to go past 6h SoT, but that doesn't matter to me. I know that I'm a rather heavy user in pretty bad conditions, especially network. Specific usage tailored to reach high amounts of SoT or battery life are of no interest to me.

I want to use my phone capabilities, like timeshifting videos, network apps, games, and still have roughly a day of usage without running out of battery. Since I'm able to do just that, that's fine.

I'm very happy with the battery life of the Z2. I'm still trying to get more time out of it, but not at the expense of being able to actually use the device, which does not seem to be the case for everyone here.
[Xperia Z2 General] Jiyeon90:
And you have never tried the Z2 *sigh*

You are comparing 3200mAh vs 2600mAh, you dont need to be very smart to realize which one performs better, not after EVERY SINGLE review puts the Z2 on top of the M8 when it comes to battery life

Enough trolling.
[Xperia Z2 General] B.K.Q:
Ok with the picture , we know that the z2 on paper is the top , but in the field not to much ,,

Because you see that the m8 and z2 has nearby result . and m8 has only 2600mah and z2 has 3200 , ( look at the numbers and look at the result )

If this 3200mah battery on the m8 we definitely expect more than 10h SoT without power saving mode .. >> we conclude from that the m8 has better battery performence because he rival the z2 and even beats him with just a 2600mah ..

Look I know that accepting the truth sometimes is hard , specially when you are a big fan of sony and z2 .. But I don't get an answer for calling me lying ? and I prove every thing i had said with pictures .. ..

Sorry if my English appears meaningless because I'm arabic and I'm working to improve it :o
