Asus was launching ZenFone 3 variants in the US as recently as a few months ago, but it also started pushing the first ZenFone 4 phones over the summer in select markets. Starting today, the ZenFone 4 series is rolling out in the US and Canada, but it's starting with the ZenFone 4 Max 5.5". This is hardly the most impressive device in the lineup, but it has a gigantic battery.

You can order a ZenFone 4 Max this very day, and maybe that's something you'd want to do if battery life is your primary concern. This phone has a modest 5.5-inch 720p display and a Snapdragon 430 SoC, but the battery is 5,000mAh. It'll probably run for days without a charge. Asus pushes the idea that you should charge other devices with this phone, but it sounds like it has a microUSB port. So, a clunky OTG cable is needed. There is also a dual camera setup with a 13MP main camera and 5MP wide-angle camera.

The ZenFone 4 Max costs $199.99 ($299.99 in Canada) and is on sale at various retailers like AmazonBest BuyB&HNewegg, and on Asus' own store. Amazon has it in stock and offers Prime shipping, but most other retailers are still showing pre-order status. The other members of the ZenFone 4 family, including the ZenFone Max 5.2”, ZenFone 4, and ZenFone 4 Pro will show up closer to the end of the year.

It has 12 safety checkpoints with automatic maintenance settings to keep the battery running optimally and provide a 2X-longer average battery lifespan than other smartphones.
