ASUS put an insanely large battery in the ZenFone Max

During its big launch event in India today, ASUS decided to throw in a surprise for those who are into phones with a massive battery: the ZenFone Max. This is one of the very few smartphones that come with a generous -- or perhaps overly generous -- 5,000 mAh cell, and you can even use the phone as a power bank to charge other devices. Like the ZenFone 2 Laser, the Max has a 13-megapixel f/2.0 main camera with laser auto-focus plus dual-tone LED flash, as well as a 5-megapixel front-facing imager and Gorilla Glass 4 on the 5.5-inch screen, though there's no word on the display resolution. The downer is the entry-level Snapdragon 410 chip with just 2GB of RAM, as if the battery life isn't already long enough.

Alas, it'll be a while until the ZenFone Max enters the market in October, so ASUS is keeping other details -- including the price -- under wraps for now. But just for reference, Gionee's mid-range Marathon M4 has the same battery capacity and goes for 15,499 Rupees or about $240, and then there's the $290 Innos D6000 with an even bigger 6,000 mAh battery plus a slightly more powerful Snapdragon 615 chip, so it'll be a tough fight for ASUS.
