Design and Build Quality
The PH31 features a sleek, modern design with rounded edges and a compact form factor. It weighs approximately 1.3 pounds (around 590 grams), making it highly portable.
The build quality is solid, with a matte finish that resists fingerprints and minor scratches. The projector includes a built-in stand that can adjust the projection angle, adding to its convenience.
Portability and Battery Life
One of the standout features of the PH31 is its built-in rechargeable battery, providing up to 2.5 hours of continuous playback on a single charge.
This makes it ideal for on-the-go presentations, movie nights, or gaming sessions without needing constant access to power. Its compact size easily fits into backpacks or large pockets.
Image Quality

Brightness: It delivers around 450 lumens, sufficient for dim or dark environments but less effective in brightly lit rooms.
Contrast Ratio: With a contrast ratio of approximately 10,000:1, the projector produces reasonably vibrant images with decent depth in darker scenes.
Color Reproduction: Colors appear fairly accurate and vibrant, though they may not be as rich as those from higher-end models.
Projection Size: The projector supports screen sizes from 20 to 100 inches, allowing flexibility depending on the viewing environment.
Connectivity

3.5mm Audio Jack: To connect external speakers or headphones.
Additionally, the projector supports wireless screen mirroring via Miracast, making it convenient to stream content from mobile devices without cables.

The built-in speaker delivers clear sound suitable for small rooms or personal use. However, for a richer audio experience, especially in larger spaces or outdoor settings, connecting external speakers is recommended.
User Interface and Features

Performance

Summary
The Optoma Photon Life PH31 is a solid choice for users seeking a compact, portable projector with decent image quality and wireless capabilities.
It excels in flexibility and convenience, especially for outdoor or on-the-go use, but its brightness and resolution limitations mean it is best suited for casual viewing rather than professional presentations or high-detail media consumption.
