Comparison Review: Asus Zenfone 5, Honor 10, Nokia 7 Plus, Oppo R15 Pro, Vivo X21,

The motivation behind writing this ranticle is fairly simple. The super premium high-end phones are getting ridiculously expensive. The iPhone X is going for S$1320, Samsung S9+ S$1020 (128GB) and Samsung Note 8 S$960 at my favourite online shops. They started off way more expensive than the going price now and they are not exactly the newest of phones to date. Do we really need to buy such expensive phones to ensure we can work properly while we are on the road?

One of the reasons why I am so interested in this was because it was not so long ago, I was in a way held ‘hostage’ by the telco contracts. For me to effectively work, only the top of the line phones does a decent job in running the Android OS. Fortunately, in the short span of 6-7, the processors that run the OS are also getting powerful and while being energy efficient even when the functions and features have increased and apps are more complicated as ever. The short answer is yes, the mid-range phones do not suck anymore.

I opined that the Android OS and apps work well even with the mid-range processors now. If you follow the news, Qualcomm has even introduced the 700 series Snapdragon processors that is as powerful as the 800 series processors you see in Samsung high-end phones. I would say the 600 series processors from the phones I just tested are as equally capable, at least for the next 2 years.

I do have other articles looking at this with a Q&A article and I will use the criteria I have shared about looking at new phones. Below is the table used in the Q&A article and I will highlight certain aspects so do keep this table handy. I will make quick work on the major areas for discussion.Brand ModelProcessorRAMStorageMicroSDEarphone JackDisplay Res.Display TypeCamera M/2/FWaterBatteryDistinct FeaturePriceRangeApple iPhone XA113GB256GBNoNo5.8-inch Full HDAMOLED12/12/7IP672716Face ID1888Crazy PremiumSamsung N8SD 8356GB64GBYesYes6.3-inch QHDAMOLED12/12/8IP683300Stylus1398Ultra PremiumSamsung S9SD 8454GB64GBYesYes5.8-inch QHDAMOLED12/12/7IP683000Slow Mo/AR Emoji1198Ultra PremiumOppo R15 ProSD 6606GB128GBYesYes6-inch Full HDOLED16/20/20–3430899HighHonor 10Kirin 9704GB128GBNoYes5.84-inch Full HDLCD16/24/24–3400Face ID579MidVivo X21SD 6606GB128GBYesYes6.28-inch FHDAMOLED12/5/12–3200In-Screen Fingerprint Scanner748HighNokia 7+SD 6604GB64GBYesYes6-inch FHDLCD12/13/16–3800Android One/Ceramic Cover599MidASUS Zenfone 5SD 6364GB64GBYesYes6.2-inch FHDLCD12/5/8–3300Ultra Wide Angle Camera488BudgetXiaomi A1SD 6254GB32GBYesYes5.5-inch FHDLTPS LCD12/12/5–3080Android One300Budget


All the phones look okay actually and it is really a matter of preference on how it looks. How the phone FEELS is also subjective because the size of our hands are also different. What I can say is about my preference and you can take it from there. I put it the Nokia 7 Plus as my favourite because it doesn’t have that mirror finish, the ceramic cover is also classy too.


All the phones that decidedly mid-range except for 2 phones. Honor, thanks to the parent company Huawei, has the same Kirin 970 as the more illustrious Mate 10 and P20 smartphones. Asus Zenfone 5 uses a slightly less powerful 636 processor but is still good enough for most users.


Between having better processors or having more RAM, I would have more RAM any day. Then again, having 4GB of RAM will last you for the next 2 years pretty easily. To ensure the phone is not being overwhelmed by numerous app, install lesser apps and stop the apps from running in the background once you shut it down and all these can be done in settings. The battery will also thank you for it too.

Storage and MicroSD Card

When I look at storage, the first thing I look for is the MicroSD card slot. Storage expansion may not mean much in the era of 128GB or even 256GB but it is also quite useful when you already have ample onboard storage like pushing videos and photos unto the card so that if anything happens to the phone, the photos and videos are saved. Besides one of the main reasons why we love Android is because of the use of expandable storage capacity and the MicroSD card slot gives me a bit of convenience.

Battery Pretty straightforward. More the better.

3.5mm Earphone Port Another one pretty straightforward. I know some manufacturers show great ‘courage’ to let go of the audio port but seriously it is one of the most useful port, especially for a photographer because I can use my call button on my hands-free earpiece as a shutter release cable. Very very useful. Besides, there are times when my wireless headset battery is dead or there are disruptions when too many Bluetooth headset are around. This is important for me if I travel far distances and want my entertainment and I won’t be hampered by the battery issue. For high-end phones that do not have a 3.5mm stereo headphone jack is really not cool. Good thing all the mid-range phones still have the 3.5mm headphone jack.

USB Port

I would have thought this should really be in the dustbin of history especially for smartphones when it comes to MicroUSB ports. I did see wireless headphones and cameras are using MicroUSB port to charge but Smartphones? The reason is simple. End of the day, I just want to quickly plug my phone to charge. When I have to align my USB cable to the phone, it is just annoying. What’s the reason for wireless charging again? Yes, plugging into the cable and USB Type-C just makes it a bit easier and is faster than wireless charging.


Practically speaking it is not much of difference in terms of day to day use. Yes, there are differences but it really doesn’t matter in the scheme of things so long the colour is more or less accurately shown to the user and bright enough to be read under the sun. I would say the reason I still put this as differentiating factor is the battery used and even that, I hardly see a huge difference too. Still, I give higher marks for AMOLED use.

User Interface

Again this is pretty subjective. For me, the native look and control are always welcomed. In this round up the surprise was Oppo R15 Pro’s gesture that replaces the ‘Back’, ‘Home’ and ‘Previous App’ soft buttons which is faster. However, the user interface also includes how I access the system menu and Android One is definitely clearer, cleaner and superior.

Besides Android One does provide a competitive advantage and it is a ‘feature’ I will place a higher weight when choosing a phone. Why? Read here.

The Camera

This is one area that one has to see to believe it and make own judgment. You can see the sample photos using this album link. I have shared the most telling comparison using this comparison photo at 100% zoom in and crop at 640 x 480 pixels. At this level it is at a ridiculous pixel peeping level already and really don’t make sense as I feel that looking at the whole picture is definitely how we appreciate photos.

Here are the close-up comparison shots. Click through to see the biggest image size good for a computer screen. In the same album, you can see the actual images and make your own conclusions.

Here I took three photos that I think are the best when I look at the bigger picture and that’s how we view photos anyway. Perceptively the Honor 10 and P20 Pro have more details generally thanks to a ‘cheat’ we called Night Scene Mode. With that in mind, the Nokia 7 Plus has done pretty well without such a mode. If I get to choose, for night shots I will take the Honor 10 but the Zeiss lens really does wonders too. Because of the ISO noise even when I used the lowest ISO settings for both the Oppo and Vivo phones, they are out of the contention. You can see the photos here.

The Nokia 7 Plus still can get a bit more details but the shadow details won’t be as good as the Honor 10 thanks to the Huawei/Honor night mode. Plus looking at the building neon sign at the top right details are definitely blown as I focus on the exposure of the clock face. Colour wise this is a bit cooler than necessary. Despite the handicap, it did pretty well. Click the image to see the original resolution.

The Honor 10’s night shots are definitely more delightful because of the phone’s Night Mode. It is an in-camera post-shot processing that merges images of multiple exposure settings to create a higher dynamic range shot of the scene. The sacrifice is the loss minute details but looking at the image as a whole it is definitely good enough. Click the image to see the original resolution.

For good measure I included the current DxO Mark champion, the Huawei P20 Pro. This won’t really be a fair comparison but to show why some of us would prefer to spend more to get a premium phone just for the camera. The P20 Pro is has a more balanced colour representation that is neither too blue nor too yellow and this alone gives the P20 Pro the leg up over both phones.

A night shot is definitely the toughest for smartphone cameras due to the insensitivity of the small sensor being used hence I wouldn’t want to be too critical. There is definitely clear winners here already but do keep in mind, there are other things such as skin tones that one should look into as well that you can see in the album link.

My conclusion is that the Nokia 7 Plus has a wee bit more quality in the images, a tad sharper, a tad better colour in some shots. The Honor 10 is a very very close second and the Night Mode is useful but only when you have tripod being used with it. These two smartphones gave me quite a lot of joy to use for photography.

The Conclusion

I tabulate the various aspects and here is the result.Asus Zenfone 5Honor 10Nokia 7 PlusOppo R15 ProVivo X21Glass BackYesYesNoYesYesAesthetics14532Processors35444RAM44455Storage45455MicroSD54555Battery23541USB Port55544Screen44455User Interface23541Camera14532Price5 ($488)4 ($579)3 ($599)1 ($899)2 ($799)Total Points3645494336

Asus Zenfone 5 – The cheapest phone and doesn’t have the same performance as the rest because of the processor it doesn’t mean it is a bad phone. It even tie with Vivo X21. If having a good camera is not at the top of your list, then the Asus Zenfone 5 won’t be a bad purchase at all. Techgoondu Review

Honor 10 – The Honor is said to be the budget P20 but I won’t say it has the same feel. It has a good camera though and has the old Huawei Night Mode but require the use of a tripod. It doesn’t have that revolutionary handheld night mode that is talk of the town now for P20/P20 Pro. Overall, it is a good phone. Techgoondu Review

Nokia 7 Plus – Too many times people will use the brand and yet doesn’t deliver. When Microsoft relaunch the brand as Lumia, the phone did not get as much attention. Now it got my attention because it has Android and not just any Android OS but under the ONE banner. HMD also did great by balancing all the necessary features and package it nicely in a body that feels more expensive than its asking price. That alone helped me choose it over the Honor 10. The camera does well too and it is really down to experience of using the camera and it pips the Honor 10 in that aspect too. Techgoondu Review

Oppo R15 Pro – The most expensive phone of the lot and quite honestly I won’t consider it as mid-range if I am looking at the price. Why did I put it as mid-range then? The processor which is decidedly mid-range. It does have good amount of RAM, battery and storage space. But the price doesn’t commensurate with the look and feel of the phone. Its camera is not totally bad but it also doesn’t excite either and it is really selfie heavy. I still don’t understand it still use the MicroUSB port. It just feel incongruent and the value proposition just isn’t there. Techgoondu Review

Vivo X21 – Vivo, along with Oppo are sister companies with the internationally well known OnePlus brand all under BBK Electronics. And I put the X21 as mid-range because of the processor being used. Its main feature? The under-display fingerprint sensor and that’s it. The feel of the phone is not exactly exciting either. It is good but so does its competitors. Like the Oppo, the value proposition is not there even though it is $100 cheaper.

On the whole Oppo and Vivo are phones that can work well but the asking price is just too much. Let me give a bit of perspective. The P20, a flagship phone, now can be bought for $730 and somehow Vivo and Oppo still feel their phones are competitive and the dead give away is the use of the MicroUSB port. If the phones want to be seen as forward-looking, USB Type C is the future. Techgoondu Review
