Still can't decide whether or not it's time to upgrade your old iPhone? Here's yet another reason to take the plunge. It looks like Apple upgraded the battery in the iPhone 6 and iPhone 6 Plus to offer faster charging speeds up from five watts to 12 watts, meaning you'll be able to power up your new iPhone much quicker than with previous models.

The upgrade was recently spotted by iLounge following some early testing with the iPhone 6 and iPhone 6 Plus, which both support 2.1 Amp power. There's a catch though. Apple is still selling its new iPhones with the 1-Amp power adapter that came with older models. To take advantage of the new feature you'll need to sub in an iPad charger or plug your handset into a Mac USB port.

At this point 2.1A has become pretty standard so it shouldn't be too hard to find a power adapter that takes full advantage of this new iPhone feature. It's nice to see Apple catching up with the competition, especially for anyone who already bought an iPhone 6 or iPhone 6 Plus. Of course, if you want the battery to last longer as well you're better off with the larger 5.5-inch iPhone 6 Plus, but at least this way it won't take as long to recharge when your phone dies on you.
