Infinix Note 50 Pro

The Infinix Note 50 Pro is the 4G model of Infinix's Note 50 family, and its spec sheet makes a clear bet: spend the budget on the things you touch and charge every day, and accept a more modest processor. It pairs a 6.78-inch AMOLED screen with a 144Hz refresh rate, a 5,200 mAh battery that charges at up to 90W (with 30W wireless charging listed in the headline features), a 50-megapixel camera with optical stabilization and a 32-megapixel front camera. Underneath sits a MediaTek Helio G100 Ultimate chip rather than a 5G processor. This page is based on the published specifications and manufacturer information from Infinix's regional pages. It explains who the phone suits and where it gives ground, without hands-on testing claims.

Where it sits in the Note 50 family

Infinix's regional product lists show several Note 50 variants, including the Note 50 Pro+ 5G, the Note 50s 5G, the Note 50x 5G and a plain Note 50. The Note 50 Pro covered here is the version that stays on 4G, which is visible in its network line: 4.5G, 4G, 3G and 2G, with no 5G bands. Infinix does not publish a single worldwide launch date or a US price for this model on the pages we could read, so the release date shown on this site is an approximation for the Note 50 series rather than a verified on-sale date, and no price is given. For a cheaper 5G take on the same family, see the separate review of the Infinix Note 50x 5G.

It also helps to place the phone against the brand's other lines. The Infinix Hot 60 Pro is aimed at a younger, cheaper buyer, while the Infinix GT 30 Pro pushes performance and gaming. The Note 50 Pro sits between them as the phone for people who want a premium-feeling body, a good screen and quick charging without paying for a flagship chip.

Design and display

Infinix describes the body as an "ArmorAlloy" metal frame and gives the thickness as 7.32 mm with a weight of 198 g, with dimensions of 163.26 x 74.43 mm. That is a slim and fairly light phone for a screen of this size, and the numbers are the manufacturer's theoretical values. Four colours are listed: Titanium Grey, Enchanted Purple, Shadow Black and a Racing Edition finish that carries a silver, striped back panel with a red and blue accent. The rear carries a large camera island with three openings and a flash, and the manufacturer's photos show the Infinix name printed low on the back. Ingress protection is listed as IP64, which means protection against dust and splashes rather than submersion, and Infinix's own footnote warns that water damage is not covered by the warranty.

The display is a 6.78-inch AMOLED panel with a resolution of 1080 x 2436 pixels (FHD+), a screen-to-body ratio of 93.4 percent and selectable refresh rates of 60, 120 and 144Hz. Infinix lists 550 nits typical brightness, 1,000 nits in high brightness mode and 1,300 nits peak, along with 100 percent DCI-P3 colour coverage, an instant touch sampling rate of 2,160Hz and PWM dimming of up to 2,160Hz. The high PWM figure is the more interesting one for people sensitive to flicker, because AMOLED panels dim by pulsing, and a faster pulse is generally easier on the eyes at low brightness. There is an always-on display mode and an in-display fingerprint reader. Peak brightness of 1,300 nits is respectable for the class rather than class-leading, so direct sunlight is the usual weak point for panels in this range.

Performance and software

The processor is the MediaTek Helio G100 Ultimate, a 6nm octa-core design with two Cortex-A76 cores at 2.2GHz and six Cortex-A55 cores at 2.0GHz, paired with a Mali-G57 graphics unit. This is the clearest compromise. It is a capable chip for messaging, video, social apps and casual games, but it is an older, 4G-only architecture and will not match the Dimensity or Snapdragon chips found in the better 5G phones. Heavy 3D games at high settings are the likeliest place where the limits show, and the very high refresh rate of the screen will mostly benefit scrolling and interface animation rather than demanding games.

Memory is offered as 256GB of UFS 2.2 storage with either 8GB or 12GB of LPDDR4X RAM. Infinix also advertises extended RAM, which borrows storage space to act as extra memory: 8GB plus 8GB in the first variant and 12GB plus 12GB in the second, and "up to 24GB" in the headline marketing. Extended RAM is a software feature, not extra physical memory, and it helps keep more apps cached rather than making the phone faster. The physical figures to compare are 8GB and 12GB. The operating system is listed as XOS 15, Infinix's Android-based skin; the page does not state a specific Android version, so check the exact build and the promised update period before buying.

Other listed hardware includes NFC, an infrared blaster, Bluetooth 5.4, Wi-Fi 802.11 a/b/g/n/ac (no Wi-Fi 6), FM radio, USB Type-C with OTG, dual SIM and dual speakers tuned with JBL, plus Hi-Res audio support and Widevine L1 for HD streaming. An X-axis haptic motor is listed too. The wireless standard stops at Wi-Fi 5, which is one more reminder that this phone is built to a price.

Camera

The rear setup is a 50-megapixel main camera with optical image stabilization, an 8-megapixel ultra-wide camera with a 112-degree field of view, as the headline features describe, and a flicker sensor that helps the camera cope with artificial lighting. There is no telephoto lens, so zoom is digital. Infinix lists video recording at up to 2K at 30 frames per second on both the front and the rear cameras, 1080p at 60 fps, and 1080p slow motion at 240 fps. There is no 4K video here, which is a real difference from the cheaper Note 50x 5G, whose rear camera records 4K at 30 fps.

The front camera is a 32-megapixel unit with an f/2.2 aperture and an 89-degree field of view, a good size for selfies and video calls. Scene modes include Super Night, Portrait, Super Macro, Street Snap, Vlog and Documents. Infinix's AI tools are positioned around a one-tap shortcut, but no benchmark scores or sample comparisons are published, so camera quality in dim rooms and with moving subjects is something to confirm in independent samples rather than assume from the sensor size.

Battery and charging

This is the phone's headline. The battery is rated at 5,200 mAh typical, and the maximum wired charging power is 90W, the sort of speed that was reserved for flagships not long ago. Infinix's feature list also names a 30W wireless MagCharge system, and reverse charging at up to 10W is listed, so the phone can top up earbuds or a second phone. Real charging time depends on the charger in the box, the temperature and the regional version, and the manufacturer labels the 5,200 mAh figure as a typical value, so the rated minimum will be slightly lower. With a 6.78-inch AMOLED panel and a 6nm processor the endurance should be healthy for the capacity, but there are no official hours-of-use claims we can quote.

Who it is for, and the trade-offs

The Note 50 Pro suits buyers who want a big, bright, smooth AMOLED screen, very fast charging, a sleek metal-framed body and a capable selfie camera, and who do not need 5G. That includes markets where 4G networks remain the standard and shoppers who keep a phone for everyday use rather than for gaming. The weaker points are the 4G-only chip, Wi-Fi 5, IP64 protection, no 4K video and a software version that is not clearly stated.

• Strengths: 144Hz AMOLED, 90W charging, wireless charging, JBL speakers, NFC, a 32MP front camera and a thin, light body.
• Compromises: 4G only, older Helio G100 Ultimate, extended RAM that is virtual, a single ultra-wide secondary camera, and no published launch price or date.
