Redmi K20 Pro vs OnePlus 7 vs ASUS ZenFone 6 vs Honor 20 vs Red Magic 3 vs Xiaomi Mi 9 – What’s the Best Value Flagship in 2019?

The Zenfone 6, OnePlus 7, Mi 9, Red Magic 3, and K20 Pro all have the Snapdragon 855, while the Honor 20 has the Kirin 980. Because of that, their performance should be equal. So it’s important to look at other aspects of each of these devices to differentiate.

Display

One of the most important aspects of any given smartphone is the display, so it only makes sense to focus on it first. It’s the very way in which you interact with your device. Because of that, you definitely want a nice display, or at least a serviceable one if the rest of the device is good enough.

Redmi K20 Pro

redmi k20 pro

The Redmi K20 Pro made waves when it was announced, with the company pitching it as a direct OnePlus 7 Pro contender for half the price. A bezel-less 6.39-inch AMOLED panel and a pop-up camera poise the Redmi K20 Pro’s display as a solid contender against the competition.

OnePlus 7

The OnePlus 7’s display is almost identical to the OnePlus 6T’s, except that it has HDR10+ certification. That means that you get a 6.41-inch 1080p AMOLED panel, although with a waterdrop notch impeding the display at the top center. If notches aren’t your thing, OxygenOS has an option to black out the status bar in order to hide its appearance, although some may prefer a notchless experience. HDR10+ is a step above HDR10, and you can read more about that here.

ASUS Zenfone 6 Display

ASUS Zenfone 6

The ASUS Zenfone 6 features an IPS LCD instead of an AMOLED panel. For some people, that may already knock it out of the race to be their next flagship. If you can look past that, you’ll be getting a 6.4-inch 1080p uninterrupted display, as the Zenfone 6 features a rather novel way to include a selfie camera without a notch. Instead of a notch or a pop-up, the ASUS Zenfone 6 has the back camera flip around to face the front, so at all times you can have an uninterrupted and bezel-less experience. The Zenfone 6 panel is also HDR10 compliant.

Honor 20

The Honor 20 is the other 1080p IPS LCD panel in this group of smartphones, coming in at 6.26-inches and an aspect ratio of 19.5:9. A polarizing feature of the Honor 20 is its camera cut out – some prefer it to a notch, others despise it even more. If you don’t mind a camera cut out, you’ll enjoy the slim bezels on all sides of the device that come as a result.

Red Magic 3

The Red Magic 3 is the ultimate smartphone for a mobile gamer. It has just enough bezels on both the top and bottom so that your palms don’t touch the massive 6.65-inch AMOLED screen while you’re playing games. This particular device has another perk over all of its competitors – native support for 90Hz that results in extra smoothness throughout the UI and supported games.

Xiaomi Mi 9

The Xiaomi Mi 9 is an interesting one for a bundle of reasons. Not only was there an update which changed the shape of the notch to a waterdrop, but there’s actually a mod you can install that will boost your screen’s refresh rate to 84Hz – astonishingly close to the Red Magic 3’s 90Hz. It isn’t known how safe the mod is, but enabling it for your favorite games and disabling it later shouldn’t cause too much damage. The Xiaomi Mi 9 has a 6.39-inch AMOLED panel.


Performance

All devices on this list are capable of greatness when it comes to performance, given that they all have flagship chipsets inside of them. Still, some may excel more than others. For example, the Kirin 980 in the Honor 20 has a considerably less powerful GPU than the Adreno 640 in its competitors on this list. All of these phones have a more than respectable amount of RAM, fast storage, and great processing power. The OnePlus 7 actually has a leg up over the others in this list thanks to its UFS 3.0 storage speed, though the noticeable difference should be minimal.

All in all, each and every one of the phones on this list is well capable of playing the latest games, browsing social media, and switching between the two to your heart’s content. You can’t go wrong with any of these phones if what you’re after is flagship performance.


Camera

The camera(s) is where these devices will differ greatly, and if you consider yourself a regular mobile photographer, it’s something that you’ll want to keep an eye out for.

Redmi K20 Pro

The Redmi K20 Pro is the only device on this list to sport a pop-up camera, coming in at 20MP f/2.2. It features a triple camera setup on the back, composed of the ever-popular 48MP f/1.8 sensor, an 8MP telephoto lens, and a 12MP ultra-wide-angle lens. It’s an extremely versatile camera setup, and Xiaomi has decent cameras even if they aren’t the best on the market. You can check out some camera samples in our review, where you will see that it is a highly capable shooter.

OnePlus 7

The OnePlus 7 is an interesting one, as it sports the same camera software as the OnePlus 7 Pro, and the same primary sensor. That means you get a 48MP f/1.7 primary sensor, but with a 5MP depth sensor to boot. It takes decent photos too, which you can also check out some samples of in our review. It has some issues, but it’s overall very capable at this price point.

ASUS Zenfone 6

The ASUS Zenfone 6’s back cameras flip around and face the front when you want to take a selfie. As a result, both the front and back cameras are composed of two sensors – a 48MP f/1.8 lens and a 13MP ultrawide lens. Ultrawide cameras are great for landscape shots, but they’re also fantastic for selfies with large groups of people.

Honor 20

honor 20

Honor being a subsidiary of Huawei means that we expect great photographs, but sadly that’s not really the case with this budget flagship. The Honor View 20 sports the exact same camera composition yet takes significantly better photographs, so we’re holding out hope that a future update will bring it to the heights we know it can achieve. You can check out some camera samples in our review here.

Red Magic 3

To be frank, the Red Magic 3 is not the phone you want if you are after a decent camera. There’s one single 48MP f/1.7 sensor on the back, with no other fancy auxiliary cameras. You can see some camera samples in our reviewin order to get an idea of what exactly it is you’re getting from this device.

Xiaomi Mi 9

The Xiaomi Mi 9 has the exact same camera setup as the Redmi K20 – a triple camera setup on the back, composed of a 48MP f/1.8 sensor, an 8MP telephoto lens, and a 12MP ultra-wide-angle lens. It’s probably one of the best devices on this list when it comes to cameras, and you can check out some sample shots in our review.


Software

Redmi K20 Pro and the Xiaomi Mi 9

I’ve grouped both of these devices together, as they ultimately run the exact same software. You get the latest version of MIUI on both of these smartphones, which is chock full of features. MIUI certainly has its issues, but the company has worked hard to improve it with updates. It’s a huge departure from stock Android though. In our review of the Xiaomi Mi 9, we go in-depth over some of MIUI’s best features.

OnePlus 7

The regular OnePlus 7 features the exact same software package as the OnePlus 7 Pro. If you think of stock Android with some small changes on top and some useful features to boot, you’ve arrived at OxygenOS. It’s fast, it’s smooth, and there’s little bloat. There’s really not a whole lot to complain about, except for the fact that depending on the phone you come from, you may find it lacking features.

ASUS Zenfone 6

Originally touted as very close to AOSP, the ASUS Zenfone 6 is really anything but. Filled to the brim with useful features, it falls short of greatness thanks to its gestures. ZenUI’s gestures are the same as One UI’s, but features like one-handed mode, screen recording, AudioWizard, and system-wide dark mode make it a strong contender for the best.

Honor 20

EMUI (Magic UI on Honor devices) has everything but the kitchen sink, although it’s certainly not the best around. If features are what you’re after, you can’t go wrong with EMUI, although some can be hard to find. It may certainly look and feel bloated, although you can get a better sense of what to expect from Mishaal Rahman’s massive review of EMUI as a whole.

Red Magic 3

Sans gaming mode and a couple of other small features, the Red Magic 3’s software experience is very close to stock Android’s. The default launcher is based on the AOSP launcher, and other apps like Contacts, Phone, Calculator, and Messages are from AOSP as well. This is a gaming phone through and through, so Nubia has opted not to add any non-gaming related features so far.


Battery

While battery life is one of the most important aspects of a smartphone, it’s hard to make sweeping statements based on the included battery size only. Hardware efficiency and software optimizations matter just as much, although it’s sometimes possible to make an educated guess.

Redmi K20 Pro

The Redmi K20 Pro touts a 4,000 mAh battery, a bit above the average when pitted against other devices on this list. MIUI is also known for taking an aggressive stance on currently running applications, meaning that you should, in theory, have pretty good battery life. Tushar Mehta who has the device and published his first impressions found that so far, the battery life is stellar. You also get support for Qualcomm QC4+, which can charge at 27W.

OnePlus 7

A 3,700 mAh battery means that you should expect similar battery life to the OnePlus 6T, possibly slightly better given the more efficient chipset. Idrees Patel in his review said it best – “Battery life is great, but it could have been even better.” A strong contender, but likely not the best on this list if longevity is what you’re after. The OnePlus 7 also only has regular, proprietary OnePlus fast charging, which comes in at 20W.

ASUS Zenfone 6

Likely to be the king of battery in general-purpose phones, the ASUS Zenfone 6 packs an absolutely massive 5,000 mAh battery. There’s not a whole lot to say here, other than that with the latest Qualcomm chipset, you really can’t expect anything short of fantastic battery life when it comes to the Zenfone 6.

Honor 20

The Honor 20 comes equipped with a 3,750mAh battery, and it also features Honor’s (Huawei’s) aggressive battery management. That combination of high-capacity and aggressive software management is what helped to make the Huawei P30 Pro one of the best devices on the market for battery life, although at the cost of app killing. That hasn’t changed here, as Zachary Wander’s review found that the Honor 20 has incredible battery life. It charges quickly too, with a 22.5W charger in the box.

Red Magic 3

Tied with the ASUS Zenfone 6, the Red Magic 3 comes with a 5,000 mAh battery as well. Max Weinbach’s reviewfound that while it does have amazing battery life, that does kind of make sense for a phone marketed towards gamers – and gamers only. Regardless, if battery life is all you’re after, you can’t go wrong with either of these 5,000 mAh devices.

Xiaomi Mi 9

The Xiaomi Mi 9 is no slouch, despite its small battery at only 3,300 mAh. It can certainly hold its own in everyday usage, which I found to be the case in my review. When it does die as well, you can charge it up with a 27W QC4+ charger, or a 20W wireless charging pad.
