The Quad HD screen of Sony Xperia Z4v doesn't seem to affect the phone's battery life

The Quad HD screen of Sony Xperia Z4v doesn't seem to affect the phone's battery life
Yesterday, Sony officially unveiled its very first smartphone with a Quad HD (1440 x 2560 pixels) display: the Xperia Z4v. Apart from having such a high resolution screen and a redesigned body, the Z4v isn't too different from the previously announced Xperia Z3+ / Z4, offering similar features - including Qualcomm's octa-core Snapdragon 810 processor, 3 GB of RAM, a 20.7 MP rear camera, and a 5 MP front-facing camera.

The Z4v also has a battery that's comparable to that of the Z3+, being just 70 mAh larger: 3000 mAh vs. 2930 mAh. As you may know, the Z3+ (just like the Z3 before it) sports a 1080p screen and offers excellent battery life: up to two days of usage time. But what about the Z4v? Is the Quad HD screen negatively affecting battery life? Well, it looks like it doesn't.

According to Sony, the 3000 mAh battery of the Xperia Z4v can, in some cases, last longer than the battery of the Z3+. For example, the Z4v can provide a talk time of up to 20 hours over 3G, while the Z3+'s 3G talk time is rated at up to 17 hours. The Z4v should also last longer when you're listening to music (up to 95 hours vs. up to 91 hours). In other areas (like standby time on LTE, or video playback time), the Z3+ is only marginally better. All in all, it looks like the Z4v's battery performance is comparable to that of the Z3+, despite the fact that the former device has a screen with a significantly higher pixel resolution. This is great news for Sony fans who may be waiting for a global flagship handset with a Quad HD screen.

As you may know, the Xperia Z4v will be available only from Verizon Wireless. It should go on sale later this summer for a price that hasn't been announced.

I don't want to be, "that guy", but let's wait for reviews first. If it does last as long as the Z3 then it certainly deserves more attention. Plus, the screen needs to be really good

Anyone who posts a stupid negative comment on every Android article on the site is really very sad. I feel sorry for you. There are more important things in life. You should go try making some friends or something.

"According to Sony" that's already a give away word. Wait for independent review before chanting like an fanboy.

Only the video playback test is relevant here, where there is reduction compared to Z3+. Talk time, standby, music playback are irrelevant to QHD or HD. Also, there is no mention of what resolution of video they used and at what brightness.

Testing the 5 inch QHD on Verizon waters. Why now?

Talk time & music playback time should be higher on Z4v just because of the bigger battery. Those two times have nothing to do with display resolution though. But Z4v video playback time definitely looks impressive compared to FHD Z3+!

We got the same argument when 720p and 1080p were introduced. When are people going to stop believing it.

Too bad they completely ruined it with a thick, heavy, ugly plastic design. The refined metal and glass build of the proper Z4 (Z3+) is a huge part of the overall package. What a waste! And the QHD screen is nothing more than BS bragging rights on a spec sheet. 1080 on such a small screen is just as good (and everyone knows it).

The thickness is the price to pay when you want in body Qi wireless charging.

8.6mm is hardly thick, and 160g feels solid, not heavy. My Z2 is 8.3mm thick and a little over 160g, so I know. Also the build is not plastic. It's a metal rim with a tiny insert-moulded plastic border with a glass back and front. The same as my Z2 and on it, you don't notice the plastic at all.

I'll believe it when I see the battery tests.

Lol no battery test and it clearly says "according to sony"... if that's how it goes then all flagships have good battery life.

I believe it. Samsung did the same with the Galaxy s5 and the quad HD version s5 of South Korea. Both had the exact same battery and lasted just as long as the 1080p version

They used oled, that as no problem with battery as ther is no backlighting like led where you need to backlight 1k more pixels over 1080p, why with oled they are just turned on as needed and are not used when using blacks as they not even turned on

But the SD 810 though.... Ruins the whole device.

Agree 100% 810 ruined many devices this year.

If the technology doesn't hurt, then it's welcome. To me it doesn't seem to hurt so higher res screens all day.

Should I get G4, Z3 plus or BlackBerry Venice?

What do you have now? I have Z3+ & Z2 & they both are awesome.

I had the Z2 and I absolutely loved it! Now using a galaxy S4 and I absolutely hate this XD I'm in Japan now and I think I'll just get the chance to buy new one in January when I go back home. And I probably won't buy the latest model because of the price, but instead a model that's released around now. You already have the Z3+? Does it overheat more than the Z2? Is the camera software improved? And do the speakers really sound more muffled than before?

Yeah, picked up from ebay (HK seller). It did get warm after playing real racing for 30 minutes (which phone won't?) I was expecting it to explode based on PA's recent activities - nope no luck. I could hold it just fine. I ran few benchmarks right then and scores were lower. So no overheating, but you get some throttling. Phone cools down literally in 2/3 minutes. Camera sw improved too - better texture and white balance in auto. Speakers are a bit better than Z2. They're a bit muffled compared to Z3 though because of the new position.

Oh that's nice, yea my Z2 got sometimes hot too, never overheated. Good to hear that of the camera! Speakers are good if better than Z2, since IMO those were amazing. Never heard the Z3, but interestingly the Z3 Compact has worse speakers than Z2 lol. Thanks bro, you were helpful!

Then u haven't use the Z4v,the battery life should be less than Z3........and again why man QHD,whats wrong with FHD?just see the displays of laptops,they haven't got to FHD yet(yes i know some laptops have FHD).......but then release a FHD flagship with high specs.....then u will see most people will buy the FHD flagship version.........and ur sales will also go high.......
