Sony Xperia XZ3 battery life test is done, here is the score

Sony Xperia XZ3 battery life test is done, here is the score
The new Xperia XZ3 is the best phone that Sony has ever made: it features the first OLED screen in the series and the screen looks gorgeous, it has a curved, elegant body that handles nicely, and the phone runs on the latest hardware, but how about battery life?

Sony included a 3,300mAh battery in the Xperia XZ3, smaller than the average for a flagship of this size, and we were concerned that users might need a bigger battery.

It turns out that all our concerns were justified.


The XZ3 just went through our proprietary battery test and it crashed and burned, scoring at the very bottom of the charts with just 6 hours and 5 minutes, while the average for a 2018 flagship is closer to 8 hours.

Battery life (hours) Higher is better
Sony Xperia XZ3 6h 4 min (Average)
Samsung Galaxy Note 9 8h 56 min (Excellent)
Samsung Galaxy S9+ 8h 5 min (Excellent)
Apple iPhone X 8h 41 min (Excellent)
Apple iPhone 8 Plus 10h 35 min (Excellent)
Google Pixel 2 XL 8h 57 min (Excellent)
OnePlus 6 8h 10 min (Excellent)
LG G7 ThinQ 6h 32 min (Average)

Compare this to the results we got from other flagship phones: the Note 9 with its large, 4,000mAh battery lasted nearly 9 hours, almost 50% as long as the XZ3, and other devices scored much higher as well.

Unfortunately, having a smaller battery than the average paired with a super high-resolution, Quad HD 6-inch screen might not be that great of an idea after all.

We have already used the phone for a while and it will last you through the day if you don't use it that much, but for those heavier users, getting through one day of use will be a concern.

The XZ3 supports a different fast-charging standard than most phones these days and it comes with a slow charger in the box, which takes nearly 3 hours to fully charge up the phone. This is way too slow and we recommend that you pick up a charger with USB Power Delivery support (such as the charger for the latest Google Pixel phones) to get faster charging times. We have measured the charging times with the charger in the box and you can see how long it takes and how it compares to other phones in the table below.

Charging time (minutes) Lower is better
Sony Xperia XZ3 178
Samsung Galaxy Note 9 109
Samsung Galaxy S9+ 105
Apple iPhone X 189
Apple iPhone 8 Plus 178
Google Pixel 2 XL 152
OnePlus 6 80
LG G7 ThinQ 107

You also have wireless charging support, so you can get a wireless charger and have the phone rest on it and stay happily charged at all times.

I suppose you mean the Note 9 lasted "50% longer than the XZ3"? Correct me if I'm wrong!

There is something very, very wrong in this test. @Phonearena, check your test, cause battery is slightly bigger than my XZP, ppi is less and the display is AMOLED - low battery usage. It is not possible, except if your unit is defect one.

We have double-checked the results, this is what we get.

Only 6 hours and 4 minutes. Your tests are clearly wrong Victor H. You have to be running something else in the background, or doing some other crap that your tests are not showing. That has to be the case. Because Sony themselves can be sued for false claims in regards to posting higher battery life values. Victor isn't it funny that others have the same XZ3 smartphones, but they can get 10 hours and 30 minutes from playing constant videos. Or 10 hours and 50 minutes from constant browsing. Or over 26 hours with constantly being on the phone. But you only manage to get a total of only 6 hours. So Victor H. if everything is on the up and up with your so called tests. Then please give us a listing of all the tasks and processes that are running in the background. You can post a link either on your page, or in these posts. You can even use paste bin or something like that. We'll be waiting for those results Victor H. BTW you jump into the battery but don't mention anything about the display being the best on the market right now. But naturally you only show battery only, and mention nothing else, right Victor.

there is a lot of chatter on the Google forums about a battery drain issue affecting the latest Android Pie build. Pixel 2 and Essential users are seeing the same.

Seriously, is no one going to do something about the part that implies the XZ3 lasted 18 hours in your tests? I'm trying to help here :|.

Phonearena has lot of traffic and I like their articles. People have been requesting PA for a long time to review their testing method as they don't coincide with real world performance or any other sites out there where they are close. Its been years and they keep ignoring readers requests. Not sure why.

guys you seriously need to change the way you test the batteries, all other websites show very different results than yours .

hey victor, so we just pretend u are the only one doing the review?? recombu and especially GSMArena already had the review of xz3 and i quote "And we have to say, the XZ3 definitely delivers. Perhaps not quite the astonishing improvement over the XZ2, we were hoping for, but the XZ3 still won't fail to last you through an entire day." so which is which??

I must say that according to GSMArena it scores 90h in their endurance test which has the Note 9 at 97h. I think that’s more in line with what you can expect.

GSMarena testing is always more reliable. Go with that. PhoneArena been smoking the good stuff again

In GSMArena's test Note 9 lasts 16% longer than XZ3 in web surfing and 69% longer in video playback. So the result from PA is quite reasonable.

What the hell are you talking about? GSMArena with the XZ3 got 10 hours and 30 minutes total time for playing videos. For web browsing they got 10 hours and 50 minutes for web browsing. For talk time they got 26 hours and 40 minutes. From Phonearena with Sony devices it's never reasonable.

You're wrong. It's not 69% longer only 59.7% longer as the figures says 16.45 hrs vs 10.30 in video playback and 20% in web browsing not 16%

Stop arguing with phonearena, anything except iPhone they will disagree

Sony's phones have been compromised one way or the other since the Z3. Never a decent all round product.

Phonearena only did a battery test, supposedly. So where is the rest of the testing? Where is the review? Phonearena doesn't test, they tell tall tales. They never mentioned that the XZ3 has the best smartphone display currently on the market. It's currently the brightest OLED right now. So where is that information?

youre wrong if ur basis is PhoneArena review.. look at GSMArena review and completely opposite of PA.

Check iPhones. On PhoneArena they are always one of the best when battery is the biggest problem in Apple's devices. It'd always interested me how it's possible?

It's phonearena, they put iPhones ahead of anything regardless of it's actual results.

especially funny when a bunch of your friends are always coming over asking for a charger!

Gsmarena tested the Sony Xperia Xz3 and Given it a 90 Hour Endurance rating with Over 26 Hour 3G Talk Time & Over 10 Hours of Web Browsing. Given that this is Gsmarena who do test using instrument, I would stand towards Gsmarena conclusion. I don't know how Phone arena test methods are but if it DOESN'T involved Measuring instruments, don't even bother to review any phones in the future. Please as a consumer I want specs, numbers & Statistic in front of me not just some words from your mouth.

When you have an iPhone 8 plus beating a Note 9. I can't take you guys seriously. I have both of these phones and the note 9 last an hour to 1 1/2 hrs longer than my 8 plus.

Even S8 has better battery life than iPhone 8 Plus. But here, it's the opposite.

sure s8 is way better

Please redo the methodology of your battery testing because what you do doesn't reflect real life scenarios whatsoever.
