[Q] Battery life with camera and 720p/1080p display? - Sony Xperia ZL

I'm going back and forth between the Xperia ZL and ZR, with battery life being an unknown factor. I'm debating whether the ZL having a non-removable battery with a 1080p display would outweigh the 720p display and removable battery of the ZR; I imagine the camera app previewing the scene on a 1080p display requires more power than on the ZR's 720p display?
On holidays I want to rely on my phone to shoot video and snap pictures, usually non-essential features (data connection/NFC/Bluetooth etc.) will be disabled. Can the ZL make it through a day with Stamina mode and heavy use (several hours of 1080p recording) of the camera?

z5 ---> z5 Premium?

Hello coming from the Z5, i had to say that's the worst mobile i had in the z series line up. May be i got a faulty handset? poor battery life and it was a mini heater. So, how is the z5 premium in these two aspects of battery life & temperature?
Cheers

I came to z5p from z2 (looks like you have owned it too) Average battery life of my z5p is almost same,but in heavy tasks (games,intensive internet surfing) z5p discharging faster than z2. And when I read books or listen the music z5p works noticeably longer than z2. Its about 30% in my experience. Heating is lower than z2 too.
By the way in FW 32.2.A.0.224 sony promised to optimize energy consumption and put back stamina mode.

Z2 & Z3 were the best in terms of battery stand by, so i am not comparing with that :highfive:
So, heating is less which is a great thing.
Also i heard after the latest updates, almost everything is displayed in 4k, is it true?
:good:

No, mostly 1080p. The phone would lag doing simple tasks, hell, it even lags when I emulate 4k from ADB.
Z5P does a good job managing heat. I think the dual heat sinks and thermal paste are doing their job
And regarding 4k, all 4k pixels are firing but resolution may not be 4k lol if that makes sense. 4k resolution becomes available in album, movies, and possibly Mozilla Firefox (I couldn't tell by looking at it but 4k option is available on yt and takes forever to buffer so I'm assuming it is?)
Well, i went ahead and made the purchase. Chrome looks beautiful and the mobile seems to be better in terms of battery life & heat management compared to the z5.
Thank you guys.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Sony Xperia XZ Premium before depleting the battery.
Then, drop a comment if you have anything to add!
Got 6hrs @ 50%

so that is the reason for your high screen time
what is your charger model ? UCH12 ?
if it is uch12 so you are using fast charge

im getting 8-9 hours with 3-3.5 hours of asphalt 8 gameplay on high graphics, one or two movies on youtube, full low brightness (35% on movies in YT), heavy facebook usage. and a lot of other things like video editing, whats, HG,G+ etc etc.
uninstalled all useless system and user apps. added play services in doze mode. reduced background activity and background data on all user and system apps.
using 1890x3360 resolution (to fix touch issues).
Im on oreo (.51) with storms DRM Fix/kernel, I used serajrs debloat script to get rid of all the useless apps, 8.45 hours with 13% left, this phone is a beast! Mobile data all day, stamina on performance, some YouTube, lots of browsing, telegram msg's, couldnt ask for better.
So are you guys getting these insane screen on times due to root? If so what are you doing to achieve this?
If not rooted what are you doing to get these kind of screen on times

Hi,
My device isn't rooted and this is what I do to get the most out of the battery...
1. I try to never allow the battery to get hot in order to prolong its excellent performance. If you're charging your phone, don't run heavy draining apps as this will greatly increase the battery's temperature. When charging my phone, I usually set stamina mode to always on and if I'm not expecting important phone calls I sometimes activate airplane mode. If you want to make and receive calls just turn off Bluetooth, wife, data and GPS while the phone is plugged in to keep the battery temperature down.
2. I used to love the Juice Defender app which was able to automatically turn off Wife/Data whenever the screen is off but sadly it hasn't been updated in so many years. Now I just manually turn off WiFi and Data whenever the phone is not in use.
3. If you're watching an offline film or reading a book, turn off your WiFi and Data. Again, if you're not looking to make calls activate Airplane Mode as this tends to lessen the battery drain especially when watching 4k movies.
4. Delete any apps that you don't use. Especially the power hungry apps!
5. I only tend to set brightness to the lowest setting when I'm in a very dark room. There's no point in always having it so low in broad daylight like a disorientated cave-dweller.
6. When you go to bed, activate stamina mode (if you want to save more juice then also activate Airplane Mode) and just make sure that it won't affect your alarm in the morning. ?
That's pretty much it for me I guess. Rooting voids the warranty and that's not something I want to do so I'm happy with my current usage and performance.
Hope this helps!

You can also try to turn off the phone, this will bring excellent battery life :cyclops:
Just kidding :silly:
By the way, root seems to improve a lot the phone, but I have Amazon warranty and would be a shame to lose it for rooting the phone

Hahahahaahahhaha
Yes that's one of the reasons why I'm not too keen on rooting. Rooting the device will also cause some issues that currently have no fix available so I'm good for now.
I can capture excellent stills and beautiful 4k footage. I get around 9-10 hours of screen on time with moderate to heavy use. Everything works as it should so I'm very happy with that.
3.5 hrs loosing 40%
I think for normal daily usage xzp got between 7-8 hrs
The seco d day reached [email protected]% of battery
Well, by my own experience, going out to work at 7:00, getting home at about 18:30 (plus commuting, as I was doing it in the bus too), I was reading an EPUB the whole day (Moon Reader+), black background with white text, the app prevents the screen from turning off, and I hardly had any reason besides lunch break to turn it off, I noticed I had forgotten the cable at the end of lunch break and took out brightness to about 35%, enough to be readable for me, it was on auto until them, no stamina mode either.
I got home with about 40% of battery left. I was quite surprised with my results.
Can get more than 20 hrs of SOT now
Look @The screenshoti taked after long day
5.5 hrs of SOT and 47% battery remaning
I get an average of 6 1/2 hours SOT with heavy gaming and brightness set to around 30%
Otherwise 2-3 days standby with medium to little use. I am impressed.
Ps. When gaming, is the screen running in 1080P or 4k?? How can we tell?

Thanks for clearing that. This means that we only get 4k when viewing 4k movies? However, by default we are getting 1080p which includes gaming.
It would be nice if we could run games in 4k. Why have a 4k screen which is only running 1080P?
Same as buying a 4k TV/Monitor and gaming at 1080P. :crying:
At least we should have an option to change resolution like a PC when gaming, would make sense.Even gaming at 1440P would look amazing. Some games have visible jagged edges which would be eliminated if running at resolutions higher than 1080P...

hey could you please us all how much you paid for the PC that lets enjoy 4k gaming? and how much room it takes.
I'm not trying to underestimate the power of Snapdragon 835, but you surely don't understand that even GTX 1080 doesn't play all the games flawlessly in 4K

Then you must not heard of GTX 1080 TI?? 30% better performance than the standard GTX 1080. I am able to play any game fully maxed, ultra settings at 4k with an average of 80-100 fps thank you very much...

Are there many drawbacks to running at Max resolution.

I have went back and forth with the 3 different resolution settings. If I look hard I can tell a little difference. At HD it is actually a little less sharp then my LG G5. Do we have any idea of the draw backs of the highest resolution? How much less battery life. Does it affect smoothness. I'll try different setting myself but was just wondering if anybody knew already.
I'm in the process of trying out the higher resolution too. I'll report back my real world use findings.

Does use a bit more power BUT a lot more RAM
I haven't measured battery use (and it would be hard to have exactly the same test conditions anyway), but I haven't noticed any real difference between FHD and WQHD in normal use. I also don't see a whole lot of difference in sharpness or image quality, but maybe someone with younger eyes than me will see a difference.
Testing max resolution for a few days now, no major battery life impact so far. No lag either.
I've been happy with the battery on max as well. At the end of the day, with almost 4 hours screen time, my battery was still 40% yesterday. LTE most of the day, some wifi.
The difference between 1480x720 HD+ and 2220x1080 FHD+ is around 20 minutes battery time over the course of the entire day I believe. Then with 2960x1440 WQHD+ you're probably looking at losing 40 minutes of battery throughout the day. And overall, each step up uses more RAM, which is expected.
In terms of a difference, I can't really tell the real difference between 720p and WQHD+ ... I mean, the screen is small already, it's a phone. It isn't like you're stretch the resolution over a Monitor or TV where you can clearly tell the difference.
I believe WQHD+ is just slightly sharper. The big difference is if you were to use a VR Headset since the screen would be very close to your face and magnified.. this is when I would recommend using WQHD+ ... FHD+ 1080p is fine for daily use and I doubt you would be able to have a noticeable battery drain.
It's truely a topic of Battery Life & Lower Temps / vs. / "Visual Fidelity" & Higher Temps. I believe using WQHD+ over the course of a year would have a considerable but not horrible wear on the battery lifespan however, considering hardware isn't impervious to aging.
I've played with both resolutions but haven't noticed a difference neither.

Will lowering resolution increase battery life?

The settings allow you to lower the resolution. I lowered the resolution to 2340 x 1080 and I don't really notice anything different.... Would this increase battery life? If so, how much?
It will definitely increase battery life.
How much will it increase depends on your usage and your apps installed. It should at max give you 10% increase.

It is well and widely known that lowering resolution won't give you increased battery life. At all
Ah thanks. I come from an xperia z3 so been using FHD screens only. I was interested in the XZ1 compact back then and one of the key points from reviewers is that the lower screen resolution(720p) saved a lot more battery vs the XZ1 at 1080p.

I think the misconception is lowering the screen resolution vs a device that maxes out at a lower resolution. Maybe it makes a difference for OLEDs...but for LCD screens, all if the pixels are still illuminated, so there's not much difference there.

Nothing but hype for the misinformed and ill-advised.
[Dopey voice]"Bruh...look what my phone can do to save battery life. Can yours?" [/Dopey voice]
Using lower resolutions use less power bc they use less gpu computational power. Youre not saving anything really from the screen itself. Think of it this way does your computer/laptop use more power running resource intensive applications or running idle?

Not that the resolution that saved power. If Sony could put their 3840x2160 resolution display into 4.3" size of XZ1 compact it still would run longer on battery than any 6.5" sized phone from similar battery even with 720p display. Because it's sheer size of screen that saves battery, not the resolution. 4.3" vs 6.5" is hefty difference. One needs more light to make 6.5" display emit light than to make 4.3" one hence one need more power.
Think about it this way, if resolution would matter then XZ Premium and XZ2 Premium would drain their batteries in a matter of minutes with 3840x2160 res displays. Right? But they work almost as long as say Galaxy S9 Plus or Note 8.

It not works like that. When your phone renders picture in 720p or 1080p it doesn't do it sitting idle. It still consumes power when rendering picture 60 times a sec. And its GPU still runs at 200MHz, maybe it needs like 230 or 250MHz for rendering picture in 1440p but is 250MHz vs 200 MHz a huge difference? I doubt it
It's not like 1440 picture rendering needs full GPU power but 720p or 1080p can be powered by idle GPU. Never was, never will. Ask devs in http://forum.xda-developers.com/android/software-hacking if in doubt
In reality ability to pick your resolution for battery life is a gimmick and doesn't really do anything.
There were no proofs that phones live longer from same charge when it's resolution lowered. Maybe it works for constant gaming, like playing games in 720p on a 1440p screen will bump battery life. But in other cases no
Taking only power consumption from the display alone, there is no different between HD, FHQ, QHD. The different is that if a game or any apps(or even system app itselfs) runs at HD, it will need less graphic computational power than running at QHD (once again, its not about the drainage from the display, its from GPU).

in reality, it's bull****. learn how GPU works. Try to ask Google devs if you don't know. They do habitate here, at XDA
It's not like it renders something and then goes to sleep turning cores off as CPU does. Instead GPU renders frame 60 times a sec and uses 203MHz either your resolution is 720p or 1080p. It can't lower frequency to 100MHz magically because it's not designed that way. So it consumes as much power working at 203MHz either rendering 720p frames or rendering 1080p frames.
Hence no battery economy achieved
