FOXX S13 5G: Best-Value 512GB Phone vs Samsung and Motorola
Short answer: The FOXX S13 5G is the best-value 512GB phone we compared. For $144.99 on FlexEmarket you get 12GB of RAM, 512GB of storage, a 6.67-inch 120Hz AMOLED screen and a 5000mAh battery. Next to Samsung, Motorola and Redmi phones selling for up to $399.99, only one other phone matched all four specs, and it costs more than twice as much.
Phone by phone
We compared RAM, storage, screen and battery, the four specs you notice every day, on the S13 and the phones people usually shop next to it. Prices checked November 8, 2026.
Storage is where the gap opens. The Samsung and Motorola phones here stop at 128GB or 256GB, a quarter or half of what the S13 holds. Samsung's own store sells its other budget Galaxy phones at 128GB too: the Galaxy A17 5G at a regular $269.99, the Galaxy A26 5G at $299.99 and the Galaxy A36 5G at $399.99.
The only phone that matches it on all four is an imported Redmi Note 15 Pro at $339.99.

Storage per dollar
Divide each phone's storage by its price and the gap gets wider.
At each seller's own price, the S13 gets 3.53GB of storage for every dollar, more than twice the next phone. That is also well under FOXX's own price: its store asks $399.99 for this 512GB model, while our FOXX S13 5G listing from Wireless Vision asks $255 less for the same phone.
The screen
The S13 has a 6.67-inch AMOLED screen at 2400 by 1080 pixels, which is full HD. AMOLED gives deeper blacks and richer color than LCD, and FOXX quotes a 4,500,000:1 contrast ratio and the DCI-P3 wide color gamut.
It refreshes up to 120 times a second (120Hz), so scrolling and games look smooth. Both Moto phones run at 120Hz too, but on LCD screens with a backlight. The Galaxy A27 and Galaxy A37 have 120Hz Super AMOLED screens like the S13, at a much higher price.
12GB of RAM, and room to keep everything
It has 12GB of real RAM, three times the Moto G (2026) and half again the 8GB in the Galaxy A37 and Moto G Power, so more apps stay open in the background. FOXX also lists "up to 12GB extended RAM", which is storage used as overflow memory. Motorola does the same with RAM Boost, and lists the Moto G Power as "8GB physical RAM + up to 16GB RAM Boost". Of the phones in the grid above, only the Redmi ties the S13 on real RAM.
The 512GB is the main draw: four times the 128GB on most of these phones. Android and the pre-installed apps take their share, as on every phone, and the rest is yours for photos, video and offline music.
Battery and charging
The 5000mAh battery matches the Galaxy A27 and Galaxy A37. The S13 charges at 33W, which FOXX rates at 50% in 30 minutes.

You can buy the FOXX S13 5G on FlexEmarket for $144.99, new and unlocked, from Wireless Vision.
