It isn’t any kind of secret that Apple included bigger batteries in the iPhone 6 and iPhone 6 Plus, and with higher capacity batteries comes longer charging times more often than not. If you happen to have an iPad charging adapter, it looks like faster charging for your new iPhone 6 or iPhone 6 Plus is a possibility.
According to a report initially published by iLounge, and corroborated by forum members within MacRumors, an iPhone 6 and an iPhone 6 Plus can be charged significantly faster if you do the charging with an iPad charging adapter, and not the standard adapter that comes out of the iPhone’s box.
Initial testing has been done with a Kill-A-Watt device and OS X system information, which revealed that the iPhone 6 and the iPhone 6 Plus match that of the iPad. This means they can be charged with 2.1A. What this means, when compared to previous iPhone generations, is that the new iPhone 6 lineup can draw up to 12W, rather than just 5W like older iPhones.
If you want to get faster charging, you can use the iPad charging adapter, or the charging adapter that comes with a newer-model MacBook.[via iLounge; MacRumors]
