FOXX S13 Gray 512GB

The FOXX S13 lands in the 90th percentile for features, packing a stunning 6.7" 120Hz AMOLED and a whopping 512GB of storage. But its Dimensity 900 chip is a letdown, scoring in the 44th percentile for performance, and the phone is dragged down further by a disastrous 1/5 customer rating. It's a spec-sheet champion that stumbles hard in real-world use.

The Dimensity 900 chip is the anchor holding this ship back. While it handles basic scrolling and app switching fine, thanks in part to that generous 12GB of RAM, it's not a powerhouse. Our benchmarks place it in the 44th percentile for performance, which translates to noticeable stutters in demanding games and slower load times compared to a Pixel 10a or OnePlus 15. The 5G and Wi-Fi 6 connectivity is a strong point, landing in the 79th percentile, so your network speeds will be solid. The 5000mAh battery is a bright spot, scoring in the 83rd percentile, and should easily get you through a full day. The 33W charging is about average, not the fastest we've seen, but it gets the job done.

Stacked against the competition, the FOXX S13 is in a tough spot. A Google Pixel 10a will run circles around it in camera quality and software polish, while a OnePlus 15 offers a dramatically faster processor and better build quality for not much more money. The S13's main party trick is its 512GB of storage and 12GB of RAM at a low price, which you simply won't find on a Galaxy S24 Ultra or iPhone 16 Pro Max. But you're making a huge trade-off in raw performance, where the Dimensity 900 is outclassed by the chips in every single one of its main rivals. It's a storage and RAM champion on a budget, but it loses in almost every other category that impacts daily use.

Pricing is a bit of a moving target, with a spread from $349 to $499 across different vendors. At the lower end of that range, the sheer volume of hardware you're getting, especially the 512GB storage and 12GB RAM, makes a compelling argument. You're getting flagship-tier memory and storage for a mid-range price. But that value proposition crumbles at the $499 mark, where you're dangerously close to much more polished and powerful competitors. If you're hunting for a deal, make sure you're paying closer to the $349 floor, because the performance and build quality don't justify a near-$500 price tag.

The FOXX S13 throws some seriously impressive specs on paper for a phone in this price bracket, landing in the 90th percentile for features. You're getting a massive 12GB of RAM, 512GB of storage, and a 108MP camera system, which is a spec sheet that would embarrass some flagships from a couple of years ago. The 6.7-inch 120Hz AMOLED is a genuine standout, hitting 900 nits of peak brightness and a 4,500,000:1 contrast ratio, making it a solid pick for media consumption. But the story gets complicated fast when you look at the whole picture. The MediaTek Dimensity 900 processor puts its raw performance in the 44th percentile, meaning it's firmly in the middle of the pack and will feel it under any real pressure. The build quality also sits at a mediocre 47th percentile, and that's before we even get to the elephant in the room: the customer feedback.

Anyone who values a smooth, reliable software experience should steer clear. The phone's performance sits in the 44th percentile, making it a poor choice for gamers or power users. If you care about build quality, the 47th percentile ranking means it feels less premium than most competitors. And with a 1/5 customer rating, the few people who bought it are sending a clear warning signal that this phone has serious software issues that specs alone can't fix.

The FOXX S13 is a classic spec-sheet warrior. It dazzles with big numbers like 12GB RAM, 512GB storage, and a 108MP camera, but the real-world experience is let down by a weak processor and questionable build quality. The display and battery life are genuinely good, making it a decent media consumption device. But with a 1/5 customer rating and performance that's below average, we can't recommend it for anyone who needs a reliable daily driver. The software experience, as echoed by the few buyers, seems to be the final nail in the coffin.
