As much as I love my Moto Q, I can't stand that its battery barely makes it through a day. Seriously, this phone cannot last 24 hours (even with very light use). So we checked out the goods on the new Moto Q9 and guess what? It's using the same battery as the old Q. Does this mean you'll have to carry around a spare battery or charger? No. The folks at Motorola claim the Q9 will last for roughly 2 days with typical use and around 4 days with hardly any use. Here's how they did it.
