A display of perfection
5" Sharp/JDI 1080p display

It takes 1080p to achieve flagship status, but a great display is more than a resolution race. Mi 4i uses a premium 5" Full HD 1080p display from Sharp and JDI, with NTSC 95% color gamut (compared to NTSC 72% on iPhone 6). Gorgeous colors are enhanced with full lamination technology for better contrast. Mi 4i includes Sunlight Display, which uses hardware-level algorithms to adjust contrast for each pixel in real time, dramatically improving readability in sunlight. All these come protected by Corning® Concore glass.

Accomplish more
with a 3120mAh battery

We've put considerable effort into fitting the highest battery capacity possible to power Mi 4i's stunning 5" display while maintaining a slim profile. This meant using the highest energy density battery technology – 4.4V 700Wh/L lithium-ion polymer cell. To save every inch of space, we then redesigned Mi 4i to include a double-sided circuit board and custom ultra-thin display. The result is an incredibly thin frame that's just 7.8mm, but with an all-day 3120mAh battery with Quick Charge that charges up to 40% in an hour.

Pump up the volume with Smart PA playback

You shouldn't have to put your phone in a glass cup to amplify sound. That's why Mi 4i has Smart PA, which amplifies sound significantly and improves playback quality while protecting speakers from damage at high volume levels. It's a difference your ears will pick up in an instant.

Designed for your hand

Anti-grease coating / 5 color options
Finely textured and matte-sprayed for resistance to fingerprints and grease, the unibody design and matte back cover is smooth to the touch and feels great against skin. The back cover fits just right and bends seamlessly across the sides to meet the front display. Available in white, with colorful versions coming soon.
