Key features
The trick with a value 5G phone is to compare the genuine total, not the eye-catching monthly figure. A low rate hiding a hefty upfront charge can end up pricier than a steady tariff once you add it all up, so sort by effective monthly cost. Choose a data allowance that suits how you really use mobile internet, and a contract length you will be comfortable with. If your existing phone is holding up, a SIM-only plan is usually the cheaper route than a new agreement.
The 6.77-inch display is one of the larger screens you will find at this price, with room to spare for streaming, gaming and reading. The dual rear camera, led by a 50MP main sensor, takes crisp, detailed photos in good light, which covers the bulk of everyday shooting. The 5MP front camera does the job for selfies and video calls. As with most budget phones, it is happiest in daylight and well-lit spaces rather than tricky low light.
Battery is where this phone really shines. The 6500 mAh cell is bigger than most rivals carry and should easily clear a full day, with many users reaching a second. At 189 g it stays manageable in the hand given the screen size. It runs Android 15 and adds 5G, so web pages, downloads and streaming load quickly where coverage allows. Performance suits everyday apps, navigation and casual gaming rather than the most demanding titles.
The Honor 400 Pro steps up to a 200MP triple camera, a sharper 50MP selfie setup, 512GB of storage and Honor AI features, all at a higher price. The 400 Smart 5G counters with a bigger 6500 mAh battery and a lower cost. Pick the Smart 5G for long battery life on a budget; choose the 400 Pro if photography and extra storage are your priorities.
The 400 Smart 5G comes with 128GB and no memory-card slot, so the space you start with is fixed. For most people 128GB comfortably holds apps, photos and some offline media. If you download a lot of video or keep a big music collection on the device, keep an eye on what you store or use cloud storage to avoid running short.
