Cubot P90 specifications and in-depth review

Cubot P90

Manufacturer: Cubot

The Cubot P90 is a large-screen smartphone built around a 6.88-inch IPS LCD panel that runs at a 120Hz refresh rate, offering noticeably fluid scrolling and navigation. It ships with Android 15, 12GB of RAM, and 256GB of internal storage, and also includes a secondary screen — a relatively uncommon addition at this tier — with a resolution of 320 x 380px. The device supports NFC, dual SIM, USB Type-C, and an external memory slot, rounding out a connectivity setup that covers most everyday needs.

Under the hood, the P90 is powered by the MediaTek Helio G100, built on a 6nm process with an octa-core CPU running at up to 2.2 GHz and paired with a Mali G57 GPU. The rear camera system consists of a dual-lens arrangement with a 64MP main sensor, while the front accommodates a 16MP shooter. Battery capacity sits at 5100 mAh with 18W fast charging supported, though wireless charging is absent. The phone lacks a 3.5mm headphone jack and does not support 5G, relying instead on LTE connectivity with download speeds reaching up to 650 Mbits/s.

Pros
  • The 120Hz refresh rate on the 6.88-inch IPS LCD panel delivers noticeably smooth scrolling and navigation for a screen of this size
  • 12GB of RAM paired with 256GB of internal storage provides a generous amount of memory and space for everyday multitasking and media storage
  • The secondary screen adds a practical secondary display surface, which is an uncommon addition in this device category
  • A 5100 mAh battery capacity with 18W fast charging support offers a reasonable combination of capacity and replenishment speed
  • NFC support enables contactless payments and data exchange without relying on additional accessories
  • The camera system offers a broad set of manual controls including ISO, exposure, focus, and white balance, giving users hands-on control over their shots
Cons
  • The 720 x 1640 px resolution results in a pixel density of just 260 ppi across a 6.88-inch panel, which means on-screen sharpness is relatively limited
  • No wireless charging or reverse wireless charging is available, restricting charging to wired methods only
  • The absence of a 3.5mm headphone jack, stereo speakers, and high-quality Bluetooth codecs such as aptX or LDAC significantly limits wired and wireless audio options
  • 5G is not supported, limiting cellular connectivity to LTE only
  • The device has no water resistance rating of any kind, leaving it vulnerable to moisture in everyday situations
  • No optical image stabilization is present, which can affect the quality of handheld photos and videos in low-light or motion-heavy conditions
Who is this for?

This device is a reasonable fit for users who prioritize screen real estate and smooth everyday navigation, as the 6.88-inch display with a 120Hz refresh rate handles casual browsing, video consumption, and social media scrolling well. The combination of 12GB RAM, 256GB storage, and a capable octa-core chipset makes it adequate for users with moderate multitasking needs who want ample space for apps, photos, and media without relying on cloud storage. Those who appreciate manual camera controls will also find value here, as the rear camera covers manual ISO, exposure, focus, and white balance, giving hobbyist photographers a degree of hands-on flexibility. The inclusion of NFC, dual SIM support, and an external memory slot further suits users who need versatile everyday connectivity and expandable storage.

Who is this NOT for?

Users who demand sharp, high-fidelity visuals will find the 720p resolution across a 6.88-inch panel noticeably soft, making this a poor fit for those who regularly view detailed content, read small text, or watch high-definition video. The complete absence of water resistance means it is ill-suited for outdoor enthusiasts, athletes, or anyone regularly exposed to rain or moisture. Those who rely heavily on audio quality — whether through wired headphones or wireless high-fidelity codecs — will be frustrated by the lack of a 3.5mm jack and the absence of aptX, LDAC, or any advanced Bluetooth audio codec. Similarly, users in areas where 5G connectivity matters or those who expect future-proof network speeds will find LTE-only support a meaningful limitation.

Final Verdict

The Cubot P90 is a large-screen Android 15 smartphone that carves out a functional but limited niche for casual everyday users. Its most compelling attribute is the 6.88-inch IPS display running at 120Hz, which, combined with 12GB of RAM and 256GB of storage, delivers a reasonably fluid experience for general use. The addition of a secondary screen, NFC, dual SIM support, and a broad set of manual camera controls show that the device aims to offer more than a bare-bones feature set. However, its HD-only resolution, LTE-only connectivity, absent water resistance, and stripped-down audio capabilities mean it falls short for users with more demanding expectations. The Cubot P90 is best approached as a device for undemanding daily tasks — those who keep those expectations in check will find it a functionally complete, if technically modest, option.
