Charge iPhone Faster Using AC power
If you’re in a hurry to charge your iPhone, plug it into the wall outlet. Apparently you can charge your iPhone 23% faster by using the AC power adapter when compared to charging the device through a USB port, according to testing and many firsthand reports. Anecdotally, I have experienced that charging an iPhone from a wall outlet is much faster as well, so try it out and you’ll quickly see yourself that the difference is pretty impressive in charging time. To get a good idea of the time, enable the battery percentage indicator on the iPhone and then watch it as it charges when plugged into the wall outlet. Magic, presto, AC adapters charge the iPhone faster!
So beyond anecdotal reports and personal experience, some testing was done as mentioned on TUAW that demonstrated the 23% charging speed increase by using a wall outlet vs USB port, and though the tests may pertain to the iPhone 4 specifically, from experience I can confirm that an AC wall adapter charges the iPhone 6, iPhone 5, iPhone 3 and 3GS quicker than USB connections to a computer as well. Every iPhone seems to charge faster in a wall outlet, not surprising, perhaps, but helpful.
Yes, You Can Charge iPhone Faster with an AC Wall Outlet
It works. There is no faster way to charge an iPhone than plugging it into a wall outlet. Try this out yourself, the difference is usually pretty obvious and pretty noticeable. Just a few minutes plugged into the wall will give it quite a bit of juice.
Another observation I’ve made relates to the power output of particular USB ports. For instance, a 2010 MacBook Pro charges an iPhone a lot faster than my Hackintosh Netbook, but still slower than the wall outlet.
Bottom line: if your iPhone is charging slowly, plug it into the wall with the AC charging adapter to speed it up! It will charge faster and you’ll be out and about again in no time.
