Teasing jibes are not uncommon in the phone industry, as demonstrated by Asus's latest broadside at Apple.
The company has taken aim at Apple's ugly new battery pack case for the iPhone, which will not only give your phone some extra juice when you need it, but will also look like it has a tumour.
In a tweet sent to promote Asus's new-ish ZenFone Max, the company said "You don't need that extra pack when you have the maximum power in one. #ZenFone #Max".
