Sony Xperia 1 II battery life

12 July 2020
We couldn't carry out our battery tests during review time, but having gotten the final firmware a few days ago, we now have the numbers.

    Sony should refocus on handheld gaming instead of smartphones. On the go gaming didn't die, like they said a few years ago. Why make part of this phone with gaming potential when google is dominating that area. I would had loved a successor to the PSVITA.

        Sony should think about the dimension of yet to be launched phones. Experia 1 II is very much taller than expected. May protrude over the pocket and look awkward.

          Android.Master, 21 Jul 2020The dimensions of those 5 inchers are pretty much the same ... morebut what use of the bigger screen?

            Phecabooth, 20 Jul 2020And that is a big problem. Why put 6+ inches on it? for me... moreThe dimensions of those 5 inchers are pretty much the same compared to modern devices except for modern devices being slightly taller.
            You can continue using those outdated devices.

              Android.Master, 13 Jul 2020Why put smaller screen? Existing screen size is not an issu... moreAnd that is a big problem.
              Why put 6+ inches on it? for me no use, easy to use 5" is more than enough.
              You can not solve everything with a bigger battery, otherwise it will lose it's purpose: Mobile.

              Personally I liked my DROID Maxx and DROID Turbo devices the most. Big batteries with long endurance.

                We are not talking about 1080p content (1920x1080). So your comment regarding the 2/3 display being off is irrelevant in this conversation, which also applies to other oled phones. The commenter was saying it's displaying 1080p 95% of the time. Unless your saying the UI and everything else is displaying at 16:9 on the phone. Which is 100% not the case.

                And no it does not turn off subpixels when displaying content. It is powering all the pixels in the display unless something 100% black.

                  Anonymous, 16 Jul 2020You're getting confused between rendering and displayi... moreThat's the great thing about modern OLED.
                  It uses a PenTile matrix, so at max resolution it shared the subpixels. And when the image is passed from the processor to the display controller, it can display the image without using all the subpixels.

                  For example, the Sony Xperia 1ii has a resolution of 3840 x 1644 (in landscape). And you decide to watch a 1920 x 1080 (landscape) video. It will scale the vertical axis to the full area, and you will have letterboxing on the (left and right sides) horizontal axis. So the image will take up the area of 2922 x 1644, leaving black bars of (459 x 1644 pixels) on the left and right sides switched off/deep-black. And inside this box of 2922 x 1644, it will only render 1920 x 1080 pixels. So in the vertical axis inside this box, it will display 2 pixels out of 3 (aka 1/1.5, or 1080/1644). Also in the horizontal axis inside the box, it will display 2 pixels out of 3 (aka 1/1.5, or 1920/2922). It does this spread out, in a uniformly, and in repeating patterns. To us the viewers, we cannot tell, because the pixels are so small, and because a "switched off" OLED doesn't register because it doesn't emit light. This saves a lot of power.

                  LCD panels cannot do this. They can't turn off individual pixels. And if any pixels get stuck, they shine an annoying bright light unevenly. So they resort to rendering the lower resolution image by duplicating certain pixels. Again, this is done spread out, uniformly, and in a repeating pattern... so as to reduce imperfections. So the LCD will still use ALL of the pixels in the display, and this means using up battery somewhat unnecessarily.

                  Despite all said, LCD still has many benefits over OLED. Besides cost and longevity, sometimes it could have an edge on sunlight legibility, brightness, accuracy, response rate. The best OLED pretty much has won on the other categories but not in longevity (burn-in) and not in cost. But another aspect is battery life. White, Yellow, Cyan, Purple, Blue are more efficient on LCD. Black, Gray, Brown, Red, are more efficient on OLED. Orange, Green, Pink are roughly equal. Of course this is a gross over-simplification of it. So you can see how browsing the web (bright colours) could be notably more efficient on LCD, but watching a dark movie could be notable more efficient on OLED.

The graphics chip may be rendering at 1080p but it is still powering the 4k display. Eg. For every 1 pixel the graphics chip is rendering it will map it to 4 pixels.

                    Is still needs to power the 4k resolution, every single one of the 6312960 pixels.

                    If it does what you are saying, turning off the pixels. you will either have a scaled down screen, 1/4 of the size, kinda like one handed mode where it scales down the whole screen. Either that or that for every 1 pixel rendered 3 other pixels are off? Does that even make sense to be turned off like that? It will look like dithering.

                      I don't think people understand that just because the resolution isn't 2160p that it is somehow not true 4k? 2160p is the res of a 16:9 aspect ratio which is why in movies you have letterbox format. With 1644p by 3840 res you have 21:9 which is movie theater resolution that's why when you go to the theater there sometimes isn't letterboxing because it's filmed in 21:9 aspect ratio. Hope this clears up any doubts as to the phone not being 4k when it actually is.

All the results I read that it is a 9to5 phone. I dont wanna worry about something like that. Pitty, everything else is what I´m looking for in a phone.

                                    On LCD displays, when showing a lower resolution, you basically have duplication of some pixels. Otherwise, the backlight will distort the overall image on any "off" pixels. This is what happens when your laptop gets a couple non-responding pixels: it shines an annoying white light constantly.

                                    But the Sony uses an OLED panel.
                                    And this can turn pixels off completely. You can actually use only 720p or 1080p pixels, by turning off the extra pixels. The panel they use is basically 1440p but slightly taller, and a lot wider. So it's not too dissimilar to say the S20's display.

                                      kgibbs29, 13 Jul 2020So much incorrect with your statements. Samsung is the OEM... moreEven more misinformation on yours.
                                      Just because Samsung made this panel, does not mean it is their best. And even if it is the best, that doesn't mean it is best at everything, as tech-products can be made for different purposes (eg Efficiency, Brightness, Contrast, Accuracy, Speed, Resolution, etc etc). So my initial point about Sony's questionable battery life performance, and the implications to the display still stands.

                                      Besides, you proved my point. If a 4K video is a resolution of 3840 x 2160, how is it possible to show that on the Sony's 3840 x 1644 display? It's not. You will have to cut the image short. Otherwise you will need to "zoom out" the image. In either case, you're losing pixels. So while on the horizontal aspect, Sony can CLAIM it is 4K, but truthfully it is not. Any 4K-UHD content will have to be cropped down to 2923 x 1644 on it. So it is a little deceptive (bordering on false advertising) to call it 4K. It is much more accurate to call this " WQHD+ " or "Ultrawide 1600" instead. If I gave you a true Ultrawide-4K video (5120 x 2160), you would realise quickly that it cannot be played natively on the handset, again cropping. Here's a wiki article: https://en.wikipedia.org/wiki/Ultrawide_formats#Ultrawide_Cinema

                                      As for other readers, who doubt the Xperia's handset has the ability to adapt it's display to the content. Well, you're in for a surprise. Sony has had this feature for a long time now. And it's only gotten more polished over time.

                                        So, let me repeat my question: how does a 4K screen work as an 1080p screen? Does it turn off 2/3 of its pixels? Does it hide it? Something else?
