Overview
The Infinix Smart 20 is a value smartphone with a big screen and a big battery. The 6.78-inch display refreshes at 120Hz, so scrolling, social media and video look smoother than on most phones in its price range, and a peak brightness of 700 nits helps you see it outdoors.
The 5200mAh battery lasts through a full day of normal use, and the phone supports 15W wired charging. 128GB of storage holds your apps, photos and videos, and you can add a microSD card for more space. The 4GB of RAM can be boosted by up to 4GB of virtual RAM to help with multitasking.
NFC support lets you share files with a tap and use compatible contactless services. Dual SIM support means you can use two numbers at once, and the side-mounted fingerprint sensor gives quick, secure unlocking. The phone is IP64-rated against dust and splashes, and it is tested for drops of up to 1.5 metres.
It runs Android 16 with XOS 16, and it has an 8MP rear camera and an 8MP front camera for everyday photos and video calls. It also keeps the 3.5mm headphone jack.
