Xiaomi Redmi A3

The Xiaomi Redmi A3 is a budget-friendly smartphone that offers decent value for its price. The phone's design is modern with clean lines, but the camera bump may not appeal to everyone. The display is nice and the battery life is surprisingly good, lasting up to 3 days on a single charge. Performance-wise, the phone is suitable for casual users who only need it for basic tasks like calls, texts, browsing, and occasional social media use. It can handle some lighter games, but hardcore gaming enthusiasts may want to look elsewhere. The phone's RAM, storage, and processor are pretty basic, making it a no-frills champion. One of the notable improvements is the charging speed, which has been upgraded to 18W fast charging. This allows for faster charging times, making it convenient for users who prioritize battery life. Overall, the Redmi A3 is worth considering if you're on a tight budget and only need a phone for the essentials. However, it's not a powerhouse device that can handle demanding tasks or high-performance games. In summary, this phone gets the job done, but doesn't excel in any particular area. It earns a 6 out of 10 rating, making it a decent value play for those who don't need much from their smartphone.

vivo Y21

The Vivo Y21 is a budget-friendly smartphone designed to compete in the upper budget segment. Priced at KSh 16,999, this device boasts an affordable tag while packing some impressive features. Design-wise, the phone has a sleek diamond glow texture that's sure to turn heads. The well-positioned volume buttons and USB-C port are also notable features. Vivo opted for a side-mounted fingerprint sensor instead of an in-display one, which works efficiently. The 6.51-inch Halo LCD display with 1600x720 pixels resolution is not high-refresh-rate enabled, but it still provides a pleasant multimedia experience. The phone's performance is backed by a Mediatek Helio P35 processor paired with 4GB RAM and 64GB storage, expandable to 1GB. While the device handles light to medium tasks without any issues, gaming performance takes a hit. Playing graphic-intensive games like Call of Duty requires medium settings, which might deter some users. However, the phone's battery longevity is noteworthy. The 5000mAh battery delivers up to two days of use on a single charge, with charging speeds that top off from 0-70% in just 52 minutes using an 18W charger. The camera setup features three sensors - an 8MP selfie camera and a 13MP dual main camera with a 2MP macro sensor. While not the best camera performer, it's still a commendable feature set for its price bracket. Overall, the Vivo Y21 is a solid budget offering that's worth considering, especially given its excellent battery life, satisfactory performance, and value-for-money pricing.
