Recently Asus took to Twitter to talk about its Asus Zenfone Max. The highlight of the Asus Zenfone Max has a 5,000 mAh battery. Asus has suggested that its Asus Zenfone Max is an alternative to the iPhone 6S owing to a long battery life. The Asus Zenfone Max has a battery life of 37 hours in comparison to iPhone 6S Smart battery case which promises a battery life between 18- 25 hours based on usage.
Asus compares the battery power of the ZenFone Max with the combined battery power of an iPhone and a Smart Battery Case, while saying: "You don't need that extra pack when you have the maximum power in one."
Asus 5,000 mAh battery can provide a talk time of 37 hous, 22 hours of internet usage and 22 hours of video playback. In comparison, the iPhone 6S provides a talk time of about 18 hours to 25 hours when used with the Apple's smart battery case for iPhone 6S.
However, Asus Zenfone Max runs Android unlike iPhone 6S which runs iOS. It is also a low end device powered by Snapdragon 410. The Zenfone Max costs much less than and iPhone. It is to be noted that Apple's Smart battery case costs almost $99.
