TCL K70 T624J Midnight Black 128GB

The TCL K70 T624J is a CAD 300 budget phone built around one standout feature: the NXTPAPER display, which reduces glare and filters blue light for easier reading. It packs a surprising amount of features for the price, including NFC, eSIM, a headphone jack, and stereo speakers. Performance and camera quality are below average, and the 720p resolution is a real compromise. Buy it for the eye-friendly screen, not for speed or photography.

The Snapdragon 4 Gen 2 is an entry-level 5G chip, and it behaves like one. In our database, this phone's performance lands in the 27th percentile, which means it's slower than roughly three quarters of the phones we track. That sounds harsh, but context matters. For everyday tasks like messaging, browsing, social media, and streaming, it's fine. Apps open, scrolling at 120Hz feels smooth enough, and the 4GB of RAM plus NXTURBO virtual RAM expansion helps keep things from grinding to a halt when you're switching between a few apps.

Where you'll feel the limits is anything demanding. Heavy multitasking, modern 3D games, or editing photos will make this phone sweat. The 4GB of physical RAM is the real bottleneck here, not the processor. If you're the type who keeps 15 apps open and expects instant switching, this isn't your phone. But if your phone use is mostly reading, texting, and the occasional YouTube video, the K70 handles it without complaint. The 120Hz refresh rate helps mask some of the chip's limitations by making animations feel more responsive than they actually are.

The competitors listed in our database are all flagships, which feels a bit unfair. The Samsung Galaxy S24 Ultra, iPhone 16 Pro Max, and Pixel 10 Pro all cost three to four times as much as this TCL. Comparing them directly is like putting a commuter sedan against a sports car. The flagships win on performance, camera, display sharpness, and build quality. No contest. But they also don't have NXTPAPER, and they cost a fortune.

A more realistic comparison is against other budget 5G phones. The Motorola Razr lineup is a foldable, so that's a different conversation entirely. The OnePlus 15 is a flagship killer that costs significantly more. Where the K70 stands out is its unique display tech and feature completeness at a low price. Where it falls behind is camera quality, which ranks in the 43rd percentile, and overall performance. If you want the best camera or the fastest phone for CAD 300, look elsewhere. If you want a reading-friendly phone with 5G and all the connectivity extras, the K70 is a niche pick that nails its niche.

At CAD 300, the K70 is priced like a budget phone, and that's exactly what it is. The value question comes down to how much you care about the NXTPAPER display. If eye comfort is a priority, there's nothing else at this price that offers anything similar. You're essentially paying for a unique screen technology and getting a competent budget phone wrapped around it.

Compared to other phones in the CAD 300 range, the K70 gives you more features than most. NFC, eSIM support, a headphone jack, and stereo speakers are not guaranteed at this price point. The trade-off is raw performance and camera quality. A similarly priced phone from Motorola or Samsung's A-series might give you a sharper 1080p display and a better camera, but you'd lose the NXTPAPER comfort factor. It's a fair trade if your eyes are the priority.

The TCL K70 T624J is one of those phones that makes you stop and ask what you actually need from a smartphone. It's not chasing flagship specs or trying to win benchmark wars. Instead, TCL went all-in on one specific idea: a display that's easier on your eyes. The NXTPAPER screen is the whole story here, and for the right person, it's a genuinely compelling one. At CAD 300, this is a budget phone with a very specific trick up its sleeve.

So who's this for? People who spend hours reading on their phone. Students, e-book fans, anyone whose eyes feel fried after a long scroll session. The 6.7-inch LCD runs at 720 x 1570, which is not going to win any sharpness awards, but the matte, glare-reducing finish and blue-light filtering are things you simply don't get on most phones at any price. TCL is betting that comfort beats pixel density for a certain crowd.

The rest of the package is what you'd expect from a budget 5G phone in 2025. A Snapdragon 4 Gen 2, 4GB of RAM, 128GB of storage, and a 5200mAh battery. Nothing flashy, but nothing broken either. The feature set actually ranks in the 92nd percentile in our database, which tells you TCL packed a lot of extras in here: NFC, eSIM, a headphone jack, stereo speakers, expandable storage up to 2TB. That's a surprisingly complete list for the price.

If you're a mobile photographer, this phone will frustrate you. The camera ranks in the 43rd percentile, and the 5MP ultrawide is genuinely weak. You'd be better served by a Pixel A-series or a Samsung Galaxy A-series phone in the same price range, both of which offer noticeably better image processing. The same goes for gamers. The Snapdragon 4 Gen 2 and 4GB of RAM simply can't keep up with modern 3D titles. Look for something with at least 8GB of RAM and a mid-range chip.

Also skip this if you're picky about screen sharpness. The 720p resolution on a 6.7-inch panel means visible pixelation, especially when reading small text or watching high-res video. If you've been using a 1080p or 1440p phone, the downgrade will be immediately noticeable. And if you need water resistance, this phone has none. For anyone who's ever dropped a phone in a sink or gotten caught in the rain, that's a dealbreaker. Consider a phone with at least an IP67 rating instead.

For the right person, the TCL K70 T624J is a genuinely smart buy. If you're a heavy reader, someone who gets eye strain from screens, or you just want a phone that feels different from the glossy glass slabs everyone else makes, the NXTPAPER display is a real differentiator. The matte finish, reduced glare, and blue-light filtering are not marketing fluff. They change how the phone feels to use for long stretches.

For everyone else, this is a harder sell. The 720p resolution is a compromise you'll notice if you watch a lot of video or play games. The camera is serviceable but nothing special. And the performance ceiling is low. If you don't care about the display tech, there are better-rounded budget phones out there. But if your eyes are tired of staring at shiny screens, the K70 offers something genuinely unique at a price that doesn't hurt.
