Yes it does this things and I like those new things but you might remember I have m7 and pretty much all new stuff that z2 got now I had 1 year ago except the 4k for which I don't care since it eats 500/600mb per minute so it's useless to me + did you forget I said I'm btw z2 and m8 and I'd pretty much like to have both of them.

To pin point what I mean :

S2w / dt2w / dt2s / f2w have this on m7

Have ois for a year now for what Sony added that stabilisation mode.

Had 1st 60fps and slow motion way back on HoX along with all these waking the phone options.

Had 1st working hdr video

Had 1st shooting the shots while in video back with HoX.

Had ips back on HoX

Hdr mics still unmatched for recording

Stereo speakers

Still the best front cam which I don't care for lol

Ir blaster still not on Sony but don't care for.

So as you see there's not much in z2 / m8 I don't have already except the s801 / 4k / larger + better screen / better battery.

So my current view is like this :

Battery the same on both

Software updates / xda HTC

Waterproof Sony

Speakers similar

Design both are beautiful

Camera usability HTC

Camera quality Sony ( with this I mean you can make better shot then with HTC if you use it manually and set it up correctly while point and shot I'd go with HTC )

Flash shots HTC

Video Sony

Display is gorgeous on Sony so Sony

So personally to me these 2 are quiet equal from my point of view the only issue I have is xda development sux on Sony vs HTC / sammy and pretty much everything else. And software updates suck as well tho I like Sony ui.

Anyway since I wanna rest from flashing and change from HTC after a while Sony is the only option for me mainly cuz only Sony matched these : speakers , design , materials , software is pretty , + waterproof which I'm dying to play with and that 5.2 screen is a killer + battery is finally great on Sony.
[Xperia Z2 General] debrandman:
While this is a battery life thread, can we please now get back tot the battery performance of the Z2? :rolleyes:
[Xperia Z2 General] KyleSforza:
But something came after Z1. ;)

http://blog.gsmarena.com/sony-xperia-z1-compact-battery-test/ - 2300 mAh

http://blog.gsmarena.com/lg-g2-battery-tests-are-done-here-are-the-results/ - 3000 mAh

About that's what paper says, I still doubt than M8 can beat even S5 when it comes to battery, let alone Z2. :p

And oh, Z2 has the reading mode too, when you're looking at screen it won't turn off, even if you aren't holding it in your hand. Once you look away the phone automatically turns off the display based on your settings.
[Xperia Z2 General] g4rvd4:
OK, looks like I'll have to eat my words.. The Z2 is back in the game (for me) with great battery life!

Waiting to hear more user reports though.. :)
[Xperia Z2 General] Shan89:
Its kinda stupid to post z1 compact battery test when it uses HD screen and much less pixels then any of the flagships. Just by resolution it uses less then any of the flagships.

I guess we'll see how s5 and z2 will do , we've seen m8 is reaching easily 7/8 SOT. Is 7/8 SOT bad for you in 30/40 hrs on battery ? How long do you expect z2 to last ? Btw why does it matter what it says on the paper when you actually see the results ? I've shown you screenshots from users and you Still refuse to accept that battery is great on m8. If we're to follow your logic of "bigger is better " how come z1 isn't better then g2 with same battery but smaller screen ?
[Xperia Z2 General] KyleSforza:
So? Now resolution is ALL that matters? lol You're funny.

Because when it comes to battery optimizations HTC < ALL.

Its their first time trying, I honestly doubt they can succeed so highly and beat the major competitors in only its first try. Its like MicroMax bringing a phone which beats all major flagships in every aspect. xD RofL

I never said battery on M8 is terrible like it was on M7. BUT what I'm saying is, if M8 has great battery life, Z2 and S5 will have greater. MUCH greater.
[Xperia Z2 General] plonkersaurus:
I don't know why you are here talking about the M8. We're here to speculate and see stats about the Z2 not about the M8.

KyleSforza was just trying to show that Sony are obviously capable of optimising a chipset as the Z1 and Z1 compact use the same one and their latest screens are more power efficient.. The Z2 apparently uses a Sharp LTPS screen (same technology as the iPhone 5S).

I think most people here were worried the Z2 would have bad battery life and whether or not it beats the M8 is largely irrelevant so it would be great if we could keep talk of the M8 to a minimum.
[Xperia Z2 General] beni8978:
With what did you measure it? [MENTION=4290357]Weldone[/MENTION]
[Xperia Z2 General] Haldi4803:
You don't measure battery performance by charging but by discharging!

P.s I've bought it on the first few days it was available. Bad strategy... Its expensive, but sometimes I can't resist xD
[Xperia Z2 General] Dendis:
PureX z2 v10 + amplify + greenify + stamina + disabled Google services

Sync off, brightness auto 50%,GPS off

Whatsapp, viber, messenger, fb,reddit, tapatalk.

If mobile data 3g(it was like for 18hrs I think) , If WiFi -2g

I got a bug where it shows that WiFi is always on, If its even disabled, but BBS say it was Offline anyway :)

What do you guys think?
[Xperia Z2 General] Weldone:
By this simple "Made In China" device

www.aliexpress.com/item/LCD-Voltmet..._78_77_80,searchweb201644_5,searchweb201560_9

Just let your device discharge to 1% and charge it with this thing connected between the phone and the charger. You will see the currency and the miliamps counter.

How many amps will get in, so many amps will get out :D

must mention

1) accuracy of this thing is very good

2) this is not a commercial :)

I think, my method is more accurate ;)
[Xperia Z2 General] Haldi4803:
To my knowledge it takes more energy to charge a battery than a battery itself can store.

But i'm not a pro on battery stuff.
[Xperia Z2 General] Weldone:
You're right, you have some power loss on heat energy. But this number is small ;)
[Xperia Z2 General] Haldi4803:
Because I'm charging with 9V the Ah is wrong, but a full charge uses 14.5Wh for my Z2

https://picasaweb.google.com/114460133623322715156/AndroidZ2#6187038259366442386

Assuming 3.8V*3200mAh should be 12.16Wh I have charged 2.5Wh to much with this Aukey PA-U28 QuickCharger 2.0

I'm fully confident that this little device is pretty accurate.
[Xperia Z2 General] muhammadnajmi96:
i can get same battery life like that without disabling sync , gps , google services hihihi . And I don't use both amplify and greenify at all. Both wifi + lte :)

Guys help me my battery is acting weird. I have gone from lollipop to kitkat and I it still drains 3-4% every hour while I'm not using. When I'm using it drains 4% every 10 minutes.
[Xperia Z2 General] Mokiwipeout:
Either something is putting strain on your CPU(probably an app), or it might be a rom problem.

In either case, I would suggest re flashing the rom you are already on, or even better, flash another rom.

Its been a 1 year 6 months with my Z2 and the battery life seems much less now. In fact now I get the same use time from both the M8 and the Z2 "Both have been bought about the same time" of a day.

Has the 3200mAh battery deteriorated ?

I am running full stock waiting for 6.0 but this reduction is really unwelcome.

EDIT: Charge it with the magnetic charging stand only dont use microusb at all.

Did anyone who are longtime users of this device get an increased battery usage after replacing your z2's old battery with a new one? Especially when on nougat based ROMs.
[Xperia Z2 General] TepaC:
Answer

All nougat based ROM's are having battery drain. So if you plan to replace your battery and expect longer work on nougat don't do that. But if your battery cant hold for one hour that's the reason for change. I'm using Carbon and my battery holds for 24h. Instagram, whatsapp, viber, fb messenger basicly i use only that app's and im satisfied with battery. Better battery performance you'll find on stock rom. :)

Someone in the m8 forums said that HTC might have underclocked the CPU, don't know if it's true but that would explain the great battery life on a device with only 2600mAh

Sent from my Xperia Z1
[Xperia Z2 General] Shan89:
Actually you're the funny one in here , Xz and s4 are both in m7 category and m7 beats both in battery life and both s4 and m7 slaughtered xz in pretty much everything , what z2 did is finally cought up with m7/m8 , m7 didn't win for no reason literally every single reward out there.

Anyway I'm done discussing with you , you obviously hate HTC.

I never compared z2 with m8 or said any of the two have bad battery in earlier posts ppl did that all I did is posted screenshots from ppl who ave m8 just so we can see how good or bad battery is. The comparison between the two is good as well since we can assume how much z2 will / should achieve and so far z2 is awesome with battery life.
[Xperia Z2 General] KyleSforza:
You sir, are totally a blind fanboy.

http://blog.gsmarena.com/samsung-galaxy-s4-battery-tests-are-done-heres-how-it-did/ - S4

http://blog.gsmarena.com/htc-one-battery-test-is-complete-results-are-in/ - HTC One M7

Compared to S4 its terrible. I do not hate any brand, but I talk with logic.

Talking of Z1, Z1 had the same old TFT. While Z1 compact makes use of the same LTPS IPS panel we see on Z2, yes shatter proof film is gone but the panel is same. Thus it conserves battery.

Anyway, in Android Authority review we saw that the phone lost only 26% charge even after a full day of usage which included 2-2.5 hours of heavy usage.

M7 Slaughtered XZ? I agree, just like XZ slaughtered HTC One X+.
[Xperia Z2 General] Shan89:
You're the one who is the blind in here , apparently you believe everything that is on paper , same z1 should be the best android camera ever yet it turned out to be pure crap unless used manually so much about paper. I rather use the device and see for myself. Did I mention I've used z1 for over a month ? You talk about phones you never used and all the stuff you say are based on what you saw on some biased site while I used both z1 and still use m7 so I know what I'm talking about and most definitely gonna use z2 and m8.

Here's my average battery life with m7 I don't think this is bad battery life as you make it to sound to be. Show me your average with z1 assuming you have it.

Anyway enough of OT.
[Xperia Z2 General] debrandman:
Aren't we here talking about Z2 battery life?I am sick and tired about you two fighting over Z1 and m7 in this thread!!!! Just go on and argue on private or somewhere else!!!!!

Can a moderator take some measures?....these two guys are destroying the entire thread with their dispute!!!!
[Xperia Z2 General] KyleSforza:
Agreed. Tired of paid fanboys jumping in here trying to derail the topic when it clearly states we discuss Z2 battery life here not Z1 or M7.
[Xperia Z2 General] Shan89:
+1

I wish i was paid lol but no , and no I'm not trolling here like I said both z2 and m8 are great devices and I'll most likely end up with both of them.

[MENTION=5807318]anonymous zzz[/MENTION]

Awesome stats mate , you've got 2:15 on that 1st half of usage with 51% and 4:37 with another 44% outstanding , with normal usage you should be at 8hrs SOT. Looking forward to see your average usage.
[Xperia Z2 General] Toledo_JAB:
Lets be honest here.

Battery life discussion threads are barely allowed on XDA.

Now if you can have a civil discussion about any phones battery life, I am ok with it.

I would like thank everyone for not going to the next level of arguing and keeping the language clean.

Keep the language clean, don't turn into a bunch of haters, and make sure each post is about some phones battery and all will stay good with me.

[Xperia Z2 General] g4rvd4:
OK, I went through the battery stats posted on this thread and most of them were with Stamina Mode ON. (Can you confirm whether it was ON all the time or only during the last moments?)

What I would like to see is how the phone performs without the stamina mode and with, separately. I mean, if you have to turn off your email downloads (and other things) while your screen is off to get this kind of battery life, it's not going to be that impressive.
[Xperia Z2 General] Sensamic:
These cheaters... :rolleyes::rolleyes:
[Xperia Z2 General] CandyAndy:
jesus christ we couldn't care less how the battery is performing on Z1 or M7. I think that many of us here are on the edge of going for M8 or Z2 since they are both beautifu and well crafted devices. Pictures we have already seen some and my personal opinion is that while on the paper M8 gets destroyed it really doesn't show that much of a difference in the real life. Therefore the battery life is going to be a major factor for any of us.

We have seen some very promising results from M8 and first signs from Z2 are looking awesome also. I wish that somebody could go head to head comparison with these two devices. Both HTC and Sony did excellent job this year.
[Xperia Z2 General] Seifer1975:
I had a first run of the Z2 yesterday on normal usage. No stamina node, on LTE throughout, Bluetooth on and connected to Sony smartwatch for about 3 hours, brightness auto but with bar all the way to the brightest. I hit about 15 hours with almost 4 hours screen on time and battery still left with 30%. Probably nothing to shout about but it is way better than what I was getting on a Note2. I have never hit more than 3 hours screen on time based on my normal usage there.
[Xperia Z2 General] MasK:
The LG G2 pampered me with amazing batt life.., thus the Z2's batt ain't impressive to me.. lol
[Xperia Z2 General] Chad_Petree:
I think battery life on the z2 would be similar to the G2, even though it has a bigger 3200 mah battery vs 3000 mah on the g2, supposedly the g2 and the one (m8) owe their awesome battery life to the self refreshing screens they have, I think the Z2 doesn't have such technology :'(

[Xperia Z2 General] msavic6:
Battery life is looking impressive on the Z2, it looks like Sony finally figured out how to better optimize their phones for battery life.

I can't wait for more tests and comparisons to be done between all of the major flagships as it looks like manfactureres have finally decided to focus on battey life.
[Xperia Z2 General] g4rvd4:
TBH, I don't think it's because of excellent software optimization. The good battery life we're seeing is just because if the massive 3200 mAh battery.If the software was anywhere as optimized as the M8's, we'd be seeing some phenomenal, mind blowing stuff.
[Xperia Z2 General] KevinB88:
It's not that impressive because M8 can get same or better battery life with 600 mAh less. And 600 mAh is a bigger difference you may think.

[Xperia Z2 General] debrandman:
Waiting for your battery stats :)...thanks in advance!
[Xperia Z2 General] Haldi4803:
Yeah sure..... And xperia z1 with 3000mAh also has great Battery life?

Nah! The new 801 brings little battery improvement but the most important part is the new Screen!

"Software optimizations " doesn't help at all,(only low level baseband stuff maybe, or wakelocks reducing...) even stuff like Stamania mode is more like cheating than battery improvement.
[Xperia Z2 General] kingrion88:
wow, asphalt 8, 2 hours.. NFC+LTE enabled throughout all the time?

4 hours 30 min SOT and 1 day&half standby.

Now this is the right definition for real-time usage. Pretty good I have to say since my brother own a note3 and it is certainly similar to note 3 with such usage. Z2 here i come!
[Xperia Z2 General] debrandman:
Wi-fi on all the time? Stamina mode...? Very good stats tho!

[Xperia Z2 General] kurtisnet:
My Z2 has phenomenal battery life too. I could hit maximum 4 hours screen on time with my Z but 7 hours screen on time with Z2 is highly possible!
[Xperia Z2 General] Shudder123:
im curious was this all on WIFI only and with stamina mode on?
[Xperia Z2 General] kurtisnet:
The first four hours screen on time was mainly all the way LTE, travelling from one train station to another for about 1.5 hour and going around shopping mall for about 2+ hours. The remaining 3 hours was spent at my university with wifi on and watching a lecture recording stream for about 2 hours.

Screen is set to about 70% brightness, and stamina mode is turned on with Gmail, Whatsapp, Viber in whitelist. Auto sync is turned on for all those services.
[Xperia Z2 General] Shudder123:
wow that's impressive. my note 2 couldn't even last that long and I can't do half those things with my current N5.. perhaps it's time to look into this haha
[Xperia Z2 General] despairados:
I was very skeptical about the battery life of this phone, given what delivered both the xperia Z and Z1 (and in a way Z1 compact which was still a bit underachieving). Battery life being my #1 priority, I was almost going to give up and buy a LG G2 despite its plastic back and the lack of micro SD port.

But this whole thread just sold me the Z2 again. I am amazed. Perfect phone. Thanks guys.
[Xperia Z2 General] Sensamic:
I get similar battery life with my SGS3. Over a day total with 3 hours SOT.

The Z2 should do much much better.
[Xperia Z2 General] chesterr:
Anyways I ordered my Z2 and waiting for a proper root exploit to the modding and uninstall all the bloat so the battery life will be more.
[Xperia Z2 General] anonymous zzz:
Awesome battery life! By the way I just realize z2 has this powersaving option,anyone already try? I wonder is this the same with Samsung and HTC cpu powersaving? :D
[Xperia Z2 General] MasK:
Here's mine:

No stamina and brightness set to auto.
[Xperia Z2 General] Shudder123:
was this all LTE?
[Xperia Z2 General] MasK:
Well, my Wifi setting was always on, but got utilized about 70% of the time when I'm at home/work. The other 30% was pure LTE.

I don't know how to interpret this.. but I think it doesn't perform as well as my previous LG G2. I'm not *****ing abt this though as this battery performance is still acceptable for my lifestyle.
[Xperia Z2 General] Ame123:
I agree with u that when the z1 was released initially the battery was disaapointing but after the 4.3 update and now the 4.4 update the battery life is amazing i am able to get 6-7 hours of screen on time with 20-24 hrs of standby. Now thats not bad at all
[Xperia Z2 General] se1000:
So, almost a full 48hrs of mixed-normal use with Wifi/LTE. It seems that the G2 benefits from the "screen ram" technology, especially for web browsing but I have zero problems with the battery life you're getting with the Z2!!!!!!
[Xperia Z2 General] MasK:
I'm sorry.. didn't quite get you. You saying is that your Z2 batt life is exceptionally better than mine?

I don't think I'm having a problem.. most users seem to have similar results..
[Xperia Z2 General] se1000:
No I was trying to explain how the G2 may actually be getting better battery life.
[Xperia Z2 General] MasK:
Ah I see.

Now don't you think if Sony used screen RAM and the panel from the G2.. it'll be a blast with 3200mAH!
[Xperia Z2 General] MSIOCGenie:
Anandtech just proved you wrong, according to their tests, the M8's battery lasts longer than the S5's.
[Xperia Z2 General] KyleSforza:
This is Z2 thread. -_-

Brag about it in HTC One forums maybe?
[Xperia Z2 General] MSIOCGenie:
Yet you were the one saying S5 would probably beat the M8, I just proved the point that you made in the first place wrong.
[Xperia Z2 General] se1000:
Totally agree. Seems as though HTC uses something similar so let's hope Sony can come up with something or license the tech from LG!
