GAMAKOO G25 Ultra S Pen Black 256GB Review

The GAMAKOO G25 Ultra S Pen offers flagship-level Snapdragon 8 Gen 2 speed and a huge battery for an absurdly low $140. The catch? You get a mediocre display and a gamble on brand support. It's a killer deal for spec hunters who don't mind the compromises.

The GAMAKOO G25 Ultra S Pen is a bit of a puzzle. On paper, it's packing flagship-tier specs like a Snapdragon 8 Gen 2 chip and a massive 6000mAh battery for a jaw-dropping price of just $140. But it's from a brand you've probably never heard of, and that comes with some big trade-offs.

You're getting a phone that should fly through apps and last for days, plus a built-in S Pen for notes and doodles. It's a spec sheet dream at a bargain bin price, which immediately makes you wonder what corners were cut to get there.

Let's be clear: the performance here is legit. The Snapdragon 8 Gen 2 is a beast of a chip, and paired with 8GB of RAM, this thing scores in the 98th percentile for speed in our database. It will handle any game or app you throw at it without breaking a sweat. The lowlight is the display, which only hits the 30th percentile. That 6.8-inch screen is HD, not the sharper Full HD or Quad HD you'd expect on a flagship, so don't expect the crispest visuals.

At $140, the value proposition is insane, and also the biggest red flag. You are getting processor and battery performance that rivals phones costing four or five times as much. If raw speed and endurance are all you care about, this is arguably the best dollar-for-dollar deal on the market. Just know you're paying for the internals, not the polish.

Stacked against the competition, it's a tale of priorities. The Samsung Galaxy S25 FE will have a better screen, camera, and software support, but costs way more and has a weaker chip. The Google Pixel 10 will crush it in camera quality and software updates. The OnePlus 15 offers a more balanced flagship experience. This GAMAKOO phone beats them all on pure specs-per-dollar, but loses badly on everything else: brand trust, display quality, and long-term software support.

If you care about having a premium-feeling phone, a gorgeous screen, a top-tier camera, or reliable long-term software support, look elsewhere. This phone makes too many compromises in those areas. Spend more on a Google Pixel, Samsung, or OnePlus for a balanced experience.

Buy this if you are a true power user on a tight budget who prioritizes raw processing speed and battery life above all else. You're okay with a so-so screen, middling build quality, and taking a gamble on a no-name brand for the sake of unbeatable performance at this price. Think of it as a performance sleeper car in phone form.
