The TCL K70 is an entry-level Android phone built around a big screen, a large battery and a low price, aimed at buyers who want the basics for calls, messaging and media without paying for extras. It keeps a 3.5mm headphone jack and a 5200mAh battery, but sticks to 4G rather than 5G and an HD+ screen.
The 6.75-inch IPS LCD runs at 120Hz for smoother scrolling than most phones at this level and reaches up to 750 nits, which should be enough for indoor use and shaded outdoor use.
The resolution is only 720 x 1570, around 256 pixels per inch, so text and images look noticeably softer than the 1080 x 2400 screen on the Motorola Moto G35 at a similar price.
The rear camera is led by a 50MP f/1.8 main sensor with autofocus, paired with a basic macro unit, and there is an 8MP front camera. In good light the main sensor should cover everyday snaps and the occasional close-up.
The second rear camera is a token 0.08MP macro rather than a useful ultrawide, so there is effectively one camera to rely on, and video maxes out at 1080p where the Moto G35 records up to 4K.
The 5200mAh battery is larger than the 5000mAh cell in the Motorola Moto G35 and, paired with the modest lower-resolution screen and an efficient 6nm Helio G100, should comfortably see out a full day of light use.
Charging is wired only with no wireless option, so it is best treated as an overnight-charge phone rather than one for quick top-ups.
At 167.7 x 79.1 x 8.3mm and 190g the K70 is large but manageable, with a glass front, plastic frame and a silicone polymer eco-leather back that should aid grip. It comes in a single Space Grey finish.
The IP64 rating covers dust and water splashes but not full immersion, unlike phones rated IP68, and the single colour leaves no room to choose.
The Helio G100 with 4GB of RAM and 128GB of storage should handle calls, messaging, web browsing and streaming without difficulty, and a microSDXC card slot lets you expand storage, though it shares the second SIM slot. It ships on Android 16.
4GB of RAM is tight for heavy multitasking, so expect apps to reload in the background, and the USB-C port runs at the older 2.0 speed, which makes wired file transfers slow.
The TCL K70 suits a buyer on a tight budget who wants a big screen, long battery life and a headphone jack for calls, messaging and streaming, and is not bothered by an HD+ display or 4G-only connectivity. Anyone who wants 5G, a sharper 1080p screen or a usable second camera should look at the Motorola Moto G35 instead.
