Right on the dot at $99, the Nokia 2 is simply the best low-cost phone you can buy. It features a sleek and sturdy design with a metal frame, along with a 1.3GHz quad-core processor and a near-stock build of Android. It's a bit lacking internally, with just 1GB of RAM and 8GB of storage, but the clean software keeps it running smoothly, and you can expand its storage with a microSD card.
The 5-inch 720p display is fairly impressive as well, but where you'll really be wowed is with the 4100mAh battery, which easily manages two days of moderate usage. It also has a surprisingly decent 8MP primary camera, as well as a 5MP selfie shooter.
Bottom line: The Nokia 2 offers clean software and speedy performance for just a Benjamin.
One more thing: Nokia has promised an upgrade to Android 8.1 Oreo soon, bringing the Nokia 2 far more up to date than anything else on this list.
