CostMvp S25Ultra Black 256GB

The CostMvp S25Ultra is a $79 budget phone with a big 5000mAh battery and 256GB of storage, but a weak processor and a camera that scores 18/100. The display is low-res and the build feels cheap. It's fine as a backup or kid's phone, but most people should spend a little more elsewhere.

The MTK6739 is a 4-core chip from the budget bin, and our database puts this phone's performance in the 26th percentile. That's not good. Apps will open, but don't expect snappy multitasking. 4GB of RAM helps a little, but the processor is the bottleneck. The display doesn't help either. 576 x 1280 on a 6.6-inch LCD is low-res by modern standards, and it lands in the 20th percentile for displays. Text will look soft. The 60Hz refresh rate is fine for this price, but combined with the weak chip, everything feels sluggish. The 5000mAh battery is the saving grace, scoring in the 66th percentile. It'll get you through a day, maybe two, because the screen and chip aren't pulling much power.

Stacked against the Motorola Moto G PB1M0006US, this thing gets smoked. The Moto G has a better display, better build, and a more capable processor for not much more money. The Samsung Galaxy S23 and Google Pixel 7 Pro are in a completely different universe, but that's expected at 10x the price. The FNCOCO I26 U is a closer competitor in the budget space, and it also struggles with similar issues. The CostMvp's one advantage is the battery, which beats many budget rivals. But battery life alone can't save a phone with a camera this bad.

At $79 USD, this phone is cheap. But cheap doesn't always mean good value. You're getting a big battery and lots of storage, but the camera is nearly unusable by modern standards and the display is a step down from what you'd find on a $100 phone from a more established brand. The 256GB of storage is nice, but the 32GB of actual internal storage mentioned in the listing is a red flag. If you need a burner phone or a first phone for a kid, the price is hard to argue with. For anyone else, save up a little more.

The CostMvp S25Ultra is a budget phone that tries to look like a flagship. The name is doing a lot of heavy lifting here. Under the hood it's a MediaTek MTK6739, a 4-core chip that was modest even when it launched years ago. You get 4GB of RAM and 256GB of storage, which sounds generous until you realize the display is a 576 x 1280 LCD running at 60Hz. This is a $79 phone in the US, and it feels like it.

The battery is the one bright spot. A 5000mAh cell paired with a low-res screen means it'll probably last a while. But the camera scores 18/100 in our database, which is rough. If you need a cheap backup phone or something for a kid, maybe. If you want a daily driver, keep scrolling.

Skip this if you care about taking photos at all. The camera scores 18/100, which puts it near the bottom of our database. Also skip it if you're used to a sharp display, because the 576 x 1280 resolution on a 6.6-inch screen will look noticeably fuzzy. If you need reliable performance for work or school, the weak processor will frustrate you daily.

This phone is for someone who needs a cheap, unlocked Android device with a big battery and doesn't care about camera quality or screen sharpness. Think backup phone, travel burner, or a first phone for a kid who will probably break it anyway. The 5000mAh battery and dual SIM support are genuinely useful. But the camera is a real letdown, and the display will annoy anyone who's used a modern phone. If you can stretch your budget by $30-50, you'll get a much better experience.
