Pros

The 5300 mAh battery supports both 100W wired and 80W wireless fast charging, with a charger included in the box and reverse wireless charging available
The triple rear camera system includes optical image stabilization, phase-detection autofocus, continuous autofocus during video, and a wide range of manual controls covering exposure, ISO, focus, and white balance
Wireless connectivity covers Wi-Fi 7, Bluetooth 5.3, NFC, and 5G, alongside satellite emergency SOS for safety in areas without cellular coverage
The Qualcomm Snapdragon 8 Gen 3 chipset is paired with 16GB of DDR5 RAM and 1TB of internal storage, offering substantial headroom for storage-intensive use
The 6.78-inch OLED display runs at 120Hz with a pixel density of 437 ppi and a 1200:1 contrast ratio, protected by Gorilla Glass 3
The IP65 rating confirms resistance to water ingress, adding a degree of durability for everyday use

Cons

No 3.5 mm headphone jack is present, requiring an adapter or wireless headphones for wired audio
The USB port is limited to USB 2.0 speeds despite using a Type-C connector, restricting wired data transfer rates
There is no external memory slot, so users are confined to the built-in 1TB of storage with no option to expand
The display does not support HDR10, HDR10+, or Dolby Vision, limiting compatibility with high dynamic range content
RAW photo capture is not available, which restricts post-processing flexibility for photography-focused users

Who is this for?

This device suits users who rely heavily on their phone throughout the day, given the 5300 mAh battery with 100W wired and 80W wireless fast charging, ensuring minimal downtime even with intensive use. Those who value camera versatility will appreciate the triple rear lens system with optical image stabilization, phase-detection autofocus, manual controls, and slow-motion video, making it a solid choice for mobile photography and video recording. The combination of Wi-Fi 7, 5G, Bluetooth 5.3, and satellite emergency SOS also makes it well suited for users who frequently travel or work in varied connectivity environments, while the 1TB of internal storage accommodates those who store large volumes of media locally.

Who is this NOT for?

Users who depend on a 3.5 mm headphone jack for wired audio will find this device incompatible without an adapter, and those who require fast wired data transfers will be limited by the USB 2.0 specification despite the Type-C port. The absence of an external memory slot means anyone needing flexible, expandable storage beyond the built-in capacity cannot accommodate that need, and users who work extensively with RAW photo formats in post-production will find the lack of RAW capture a meaningful limitation. Additionally, the display's lack of HDR10, HDR10+, or Dolby Vision support makes it a poor fit for users who regularly consume high dynamic range content and expect full format compatibility.

Final Verdict

The Honor 300 Ultra is a well-specified smartphone that covers the essentials with considerable depth — from its Snapdragon 8 Gen 3 chipset and 1TB of internal storage to its versatile triple-camera system and broad wireless connectivity spanning Wi-Fi 7, 5G, and satellite emergency SOS. Its most defining practical strength is the battery setup, combining a 5300 mAh cell with 100W wired and 80W wireless fast charging, which makes it a dependable option for users with demanding daily routines. Certain trade-offs, including the USB 2.0 limitation, the absence of a headphone jack, and the lack of RAW photo capture, mean it will not satisfy every user profile, but for those whose priorities align with sustained performance, charging flexibility, and camera breadth, the Honor 300 Ultra represents a thoroughly capable device within its category.
