Mi Max 3 is your guy. With unpretentious metal body and a gigantic 5500 mAh battery, it has the wherewithal to last from Friday afternoon to Monday morning no matter what you throw at it.
Xiaomi equipped it with the same proven hardware is placed in the Note 5, namely frugal Snapdragon 636 chipset and 1080p LCD display, and gave it the best budget camera kit it currently has - the dual camera from the Note 5 Pro AI edition, with 1.4 micron pixels and dual phase-detection autofocus that makes recording videos a smooth and sharp affair. Don't expect the low-light wonders of current flagships, but this set will do the trick just fine for most purposes.
Even the most basic memory configuration of the Mi Max 3 is pretty generous, at 6GB RAM/64GB storage, and goes for the equivalent of $250/€220 in China, but tack on at least 20% more when the thing crawls out of the Great Wall. The 6GB RAM/128GB storage version is fifty bucks more, and the available colors for the metal chassis are Black, Champagne Gold, and Blue.
At 6.94 x 3.44 x 0.31 in (176.15 x 87.4 x 7.99 mm) and 7.80 oz (221 g), the Mi Max 3 is certain to be your best friend in the dark alleys after a long night out, too, and we aren't talking about the low-light camera modes.
