Work Performance – PC Mark
We tested the ZenFone 3 Ultra‘s performance using PCMark, which simulates work applications like web browing, playing video, writing text and editing photos.
| ASUS ZenFone 3 Ultra | HTC 10 | honor 5C | Samsung Galaxy S7 edge | |
| Work Performance Score (Average) |
6313 | 6105 | 5357 | 4892 |
| Web Browsing | 6257 | 5782 | 5643 | 6908 |
| Video Playback | 4287 | 3321 | 4487 | 3218 |
| Writing | 7166 | 7463 | 5944 | 4629 |
| Photo Editing | 8262 | 9694 | 5469 | 5563 |
The Qualcomm Snapdragon 652 processor powering the ZenFone 3 Ultra did very well in this test, beating even the Snapdragon 820 processor used by the HTC 10, and the Samsung Galaxy S7 edge‘s Exynos 8890 processor.
Battery Life – PCMark
We then tested the ZenFone 3 Ultra‘s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.
Thanks to its 4,600 mAh battery, the ASUS ZenFone 3 Ultra lasted almost 11.5 hours in this test. This is twice the battery life of the HTC 10 smartphone! Of course, the ZenFone 3 Ultra has 50% more battery capacity, but it also has a much larger display that uses more power.
It was not the best battery life we have seen in a phablet though. The Samsung Galaxy A9 Pro still has the most exceptional battery life at 13 hours, albeit with a slightly larger 5,000 mAh battery and a longer recharge time.

Battery Recharging Performance
The ASUS ZenFone 3 Ultra comes with an 18W fast charger that supports Qualcomm Quick Charge 3.0. What this means is you can recharge 60% of its battery in just 45 minutes.
It actually took the ZenFone 3 Ultra just under 114 minutes (1 hour 55 minutes) to recharge its battery from 16% to 100%. That’s a battery life : recharging ratio of 6:1 – very impressive!
As the chart shows, the fastest charging happens up to about the 80% point. It took only 60 minutes to recharge from 16% to 80%.

It’s a pity that the Zen Phone 3 Uttra has The same screen resolution of the other smaller phones. Just seems a waste of potentially a great big display.
They could have gone with a 1440p display, but that would mean greater cost and power consumption for arguably no real benefit. With a pixel density of 324 ppi, it would certainly qualify as a “Retina display” at the standard viewing distance.
Remember – this is a large phablet, so we are more likely to view it at a distance. You can’t tell the difference with say, the Galaxy S7 edge, unless you compare them side by side and peek close-up.
As all three devices have the same resolution the DPI would change depending on the display size. The Ultra would not give you anymore screen realestate just a larger display. The idea of a phablet would be to increase screen realestate to make it a more productive device compared with a smaller ( non Phablet ) phone.
I would love to see manufacturers take the phablet size of six inches or larger and turn them into higher end devices rather than the middle spec devices we are seeing now.
Correct, the ZenFone 3 Ultra won’t give you more pixels, just a larger screen.
If you are viewing movies on a range of phablets at a distance of, say… 10 inches, a larger screen is arguably more enjoyable, but the higher resolution on any of these phablets won’t be noticeable.
If you are looking to work on a phablet, then yes, the higher resolution will matter… a LOT. Sadly, the only phablet that is close to 6″ with 1440p resolution is the Galaxy Note7.
Peter you are right!
Im looking to replace my aging xperia z3 tablet compact which is 8inch to a slightly smaller 6+ inch phablet. But it seems non of the newer phablet are high end devices.
Even Sony’s XA Ultra is powered by the mediocre Mediatek chipset instead of something higher end.
The Ultra was something I was considering but the price for that mid range chipset seems a bit too much also…
Hi Terence,
I have a real problem with manufacturers building large screen devices with questionable specifications. If these devices where cars then they would have an SUV chassis with a compact cabin being powered by a small 1.6 litre engine. What’s the point?
Why not manufacture a large screened phablet with high end specifications and call it a flagship device. Just giving a phone a large screen without the benefit of higher resolution just makes it suitable for media consumption rather than a device suitable for media creation and productivity.
Hi..just to ask from your experice reviewing this phone..did you noticed that the website,whatsapp and facebook app display are quite small despite the big screen size.The good thing is we can see more things in a screen.I tried changing to fonts to largest size but it is still the same
i did comparison with xiaomi mi max..the display of a website in mi max is larger and fit the screen
I suspected this is related DPI optimization
Can you give some comments?
That may be due to the higher resolution 1080p display. The icons and text will seem smaller, if you are migrating from a lower resolution 720p display, for example. Then again, the Xiaomi Mi Max has the same resolution.
Unfortunately, we no longer have the ZenFone 3 Ultra with us, so we cannot confirm it on our end… 🙁
