This $570 Android phone crushes the iPhone 14 Pro in one big way

I find myself unable to use smartphones at night because they strain my eyes, which in turn causes headaches. If you are anything like me, you probably dislike having a smartphone screen in front of you in conditions when light is dim ot nonexistent. Or worse, you might have developed Pulse-Width Modulation (PWM) sensitivity, which can make you feel nauseous when using a phone at night. This is solved by the Honor 90.

I’m privileged to have multiple phones at my disposal, and the Honor 90 has become my go-to phone for nighttime reading and research because of its 3840Hz PWM display. But to understand the solution, we must first understand PWM dimming and its effects on human eyes.

What is PWM dimming, and how does the Honor 90 help?

All smartphone screens, whether LCD or OLED, are made up of small LEDs that turn on and off to allow you to view what’s on the display. Almost all flagship phones today feature OLED displays.

But LEDs work on digital signals, meaning that an LED can either be on (1) or off (0) – there is no intensity like analog signals between 0% and 100%. When you adjust screen brightness, the LEDs aren’t dimming or brightening, but the duration between the LEDs staying on and off is changing.

This process of rapid toggling of LEDs is called Pulse Width Modulation or PWM dimming. My friend Nicholas Sutrich, a PWM-sensitive person, did a deep dive on screen flickering over at Android Central, which I recommend you read.

If the flickering speed is high, it allows the human eye to perceive that the screen is on continuously. On the other hand, a low flicker rate strains the eyes, which can cause nausea and headache. Imagine a torch being rapidly turned on and off in a dark room – it’ll cause problems for your eyes. But if the toggle frequency is very high, it wouldn’t affect the brain as badly, and it’ll interpret the light as being constantly on.

The Honor 90 offers an extremely high PWM rate of 3,840Hz, which is almost 8x faster than the iPhone 14 Pro Max and up to 16x faster than the flagship Samsung Galaxy S23 Ultra or Samsung Galaxy Z Fold 5. As a result, I haven’t had a headache or felt the Honor 90 display straining my eyes in low brightness. The phone also has a Circadian Night Display feature that adjusts the screen’s brightness to match your circadian rhythms. These two features combine to offer a better visual experience than almost all other phones.

A solid Android phone across the board

The Honor 90 features a 6.7-inch OLED display with a 1200 x 2664 resolution and 120Hz refresh rate. It also supports HDR10+ media. I’ve had a positive experience watching content on Netflix, Amazon Prime, and YouTube. The screen is bright and vivid. And because of the quad-curve display, it feels like the bezels are minimal, making the viewing experience more enjoyable. It can go up to 1,600 nits in brightness, which is decent for legibility in direct sunlight.

I like Honor 90’s design because it is comfortable to hold and light on the wrist at 183 grams. The matte texture helps with the in-hand feel too. It’s got a gradient texture that makes the phone look good. My only complaint here is the lack of stereo speakers.

I’m not a fan of the two circular camera modules at the back, but I’m not complaining too much because they pack a 200MP primary camera, which offers large images that can be zoomed in while still retaining the details. It’s got good dynamic range and color output. Shots captured through the 12MP ultrawide lens look great in bright daylight. Like other ultrawide cameras on the market, the images from this one come out soft in lowlight conditions. There’s a 2MP depth sensor, which isn’t functional as a third camera, but might help with portraits. On the front lies a 50MP selfie shooter, which is pretty good.

The Honor 90 is powered by the Qualcomm Snapdragon 7 Gen 1 chip, paired with 8GB/12GB of RAM and 256GB or 512GB storage. It runs MagicOS 7.1, based on Android 13, which still feels a bit cluttered to me. In day-to-day use, I haven’t faced any lag or stutters in the UI. From app switching to multitasking, it’s been a smooth experience. It packs a 5,000mAh battery with support for 66-watt fast charging. It will last you an entire day with ease.

More of this, please

At 450 British pounds in the U.K., the Honor 90 is a solid midrange device. It’s got the best display in the segment, a comfortable-to-hold design, a good 200MP camera and performance, and an all-day battery life.

It’s hard to say if Honor’s laser focus on PWM dimming will inspire other companies to follow suit, but I certainly hope it does. It may not be the flashiest feature around, but it is one of the most important — and something Apple, Samsung, and other companies should be paying just as much attention to.

As a parent, there’s one iPhone 15 feature I can’t wait to use
Apple promotional image of the iPhone 15 Pro's camera and curved chassis.

Apple’s next-generation iPhone 15 and iPhone 15 Pro models are finally here. The entire iPhone 15 lineup has Dynamic Island and USB-C. With the standard iPhone 15, you get the A16 Bionic that was introduced last year, and the iPhone 15 Pro models get the new A17 Pro chip and Action button. And if you opt for the iPhone 15 Pro Max, you also get the brand new tetraprism telephoto lens for 5x optical zoom capabilities.

While the new hardware changes are nice, Apple also has some new software features that are exclusive to the iPhone 15 lineup. One of these is the new Auto Portrait mode, and as a parent of a very active toddler, this is one of the most exciting things for me about the entire iPhone 15 lineup.

I tried Android 14 on my OnePlus 11 — and I’m not impressed
OxygenOS with Android 14 beta on OnePlus 11.

Android 14 is in the final stages of development, and its first stable version is set to release later this month. As a result, Android phone brands are starting to unleash previews of their upcoming software upgrades based on the Android 14 beta, allowing select users to try out forthcoming features before other people. After Samsung opened up One UI 6 beta for a limited number of devices earlier this month, OnePlus is giving us a peek at its upcoming OxygenOS 14 beta based on Android 14.

OnePlus' custom Android skin, OxygenOS, received a major overhaul last year after merging the codebase with the ColorOS interface offered by its parent company, Oppo. Our worst fears came true when OxygenOS 13, based on Android 13, was released last year. It received a radical design overhaul that most OnePlus purists deemed a downgrade that made it nearly indistinguishable from Oppo's ColorOS.

I’ve had the iPhone 15 Pro Max for 48 hours. Here are 3 things you need to know
Someone holding the Natural Titanium iPhone 15 Pro Max.

It's finally here, folks: new iPhone season. Apple's iPhone 15 event wrapped up over a week ago, the first iPhone 15 reviews are trickling out, and it won't be that long before you start seeing the new lineup in every Best Buy and Target you go to.

My iPhone 15 Pro Max arrived on September 20, and at the time of publishing this, I've been using it for just about 48 hours. That's obviously not enough time for a full review, but during that limited amount of time, I've already learned some really important things about Apple's latest entry in the Pro Max family. It's very familiar in a lot of ways, but there are three specific changes that could make it a more worthwhile upgrade than expected — and I'm not talking about USB-C.
Titanium is a game-changer for the iPhone
