What to Expect from a 5G Phone Under $400 in 2025

Performance You Can Rely On

Most phones in this price range pack Qualcomm Snapdragon 695/6 Gen 1 or MediaTek Dimensity 6100+/930 chipsets. These offer solid everyday performance for social media, video calls, casual gaming, and multitasking.

Display & Build Quality

You’ll find 6.5–6.7″ displays, typically with FHD+ resolution and a 90Hz or 120Hz refresh rate. AMOLED is becoming more common, offering vibrant colors. Build materials are usually plastic, but well-crafted.

Cameras That Don’t Disappoint

Expect 48MP–108MP main sensors with decent HDR and night mode. Ultrawide lenses are available in some models, though macro and depth sensors are usually for marketing.

Battery Life & Fast Charging

Most phones feature 5000mAh batteries with 18W–50W charging. While not the fastest, you’ll still get all-day battery life and a decent top-up in under 30 minutes.

Software Support & 5G Bands

Samsung and Apple lead in software updates, while others like POCO and Motorola offer shorter cycles. Band compatibility for US carriers is mostly covered in unlocked models.
