Honor 300 Pro specifications and in-depth review

Honor 300 Pro

Manufacturer: Honor

The Honor 300 Pro is a large-screen smartphone built around a 6.78″ OLED/AMOLED panel with a pixel density of 437 ppi and a 120Hz refresh rate, offering sharp and fluid visuals backed by Gorilla Glass 3 protection. The device runs Android 15 and includes a broad set of software features such as dark mode, split-screen multitasking, dynamic theming, and on-device machine learning, making it a feature-rich option within the smartphone category.

Under the hood, the Honor 300 Pro is powered by the Qualcomm Snapdragon 8 Gen 3 chipset, built on a 4 nm process, paired with 16 GB of LPDDR5 RAM running at 4800 MHz and 512 GB of internal storage. Its triple rear camera system combines 50 MP, 50 MP, and 12 MP sensors with 3x optical zoom and OIS, while the front houses a dual-lens 50 MP and 2 MP setup. The 5300 mAh battery supports 100W wired and 80W wireless charging, along with reverse wireless charging, and connectivity options include Wi-Fi 7, Bluetooth 5.3, NFC, and 5G support.

Pros
  • The 5300 mAh battery supports both 100W wired and 80W wireless charging, along with reverse wireless charging, covering a wide range of charging scenarios
  • Wi-Fi 7 support alongside 5G connectivity and dual SIM capability makes it well-suited for demanding network use
  • The triple rear camera system includes optical image stabilization, 3x optical zoom, phase-detection autofocus, and an extensive set of manual controls, offering considerable shooting flexibility
  • 16 GB of DDR5 RAM paired with 512 GB of internal storage provides ample headroom for multitasking and local content
  • The IP65 rating offers reliable protection against dust and water jets, adding durability for everyday use
  • Stereo speakers combined with aptX HD Bluetooth support give a reasonable range of audio output options
Cons
  • The 3.5 mm headphone jack is absent, limiting wired audio options to USB-C adapters
  • There is no external memory slot, making the 512 GB of built-in storage the fixed ceiling for local files
  • The display does not support HDR10, HDR10+, or Dolby Vision, and lacks an Always-On Display mode
  • OS updates are not delivered directly from the vendor, which may affect the timeliness of software and security patches
  • The USB port is limited to USB 2.0 speeds despite using a Type-C connector, restricting wired data transfer rates
Who is this for?

This device fits users who rely heavily on their smartphone throughout the day and need a reliable charging setup, as the 5300 mAh battery with 100W wired and 80W wireless charging ensures minimal downtime. The combination of a 6.78″ 120Hz OLED display, Snapdragon 8 Gen 3 chipset, and 16 GB of DDR5 RAM makes it a solid fit for those who regularly switch between demanding apps, stream content, or engage in extended gaming sessions. Photography enthusiasts who want granular control over their shots will also find value here, thanks to the triple rear camera system with OIS, 3x optical zoom, and extensive manual controls covering ISO, exposure, focus, and white balance. The dual SIM slot with 5G and Wi-Fi 7 support further suits frequent travelers or users who need fast, flexible network access across different connections.

Who is this NOT for?

Users who prefer a compact, lightweight handset may find the 163.8 mm height and 199 g weight uncomfortable for prolonged single-handed use. Those who work extensively with wired audio will be immediately limited by the absence of a 3.5 mm headphone jack, as no adapter is included. The fixed 512 GB internal storage with no external memory slot means users who manage large local media libraries or need expandable storage will hit a hard ceiling. The display's lack of HDR10, HDR10+, or Dolby Vision certification makes it a poor match for users who prioritize high dynamic range content consumption. Additionally, those relying on direct manufacturer OS updates for timely security patches will find the indirect update model a drawback, and the USB 2.0 transfer speeds may frustrate users who frequently move large files between the device and a computer.

Final Verdict

The Honor 300 Pro is a well-specified smartphone that covers a wide range of daily demands, anchored by a capable Snapdragon 8 Gen 3 chipset, a sharp 6.78″ 120Hz OLED display, and a versatile triple rear camera system with OIS and meaningful manual controls. Where it stands out most is in its charging ecosystem — 100W wired, 80W wireless, and reverse wireless charging backed by a 5300 mAh cell is a combination that few devices in this category match. Some trade-offs are present, including the absence of a headphone jack, a USB 2.0-speed Type-C port, and a display without HDR certification, which will matter to specific user groups. Overall, the Honor 300 Pro is a practical choice for users who prioritize sustained performance, fast power recovery, and photographic flexibility, provided they are comfortable within its connectivity and display limitations.
