Charge iPhone faster using AC power
Jul 12, 2010 - 6 Comments
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.
The tests which are mentioned on TUAW pertain to the iPhone 4 specifically, but from experience I can confirm that an AC wall adapter charges the iPhone 3 and 3GS quicker than USB as well.
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 to speed it up!
same applies to else mac hardware?
Have you guys plugged your iPhones into an iPad charger?
I have done this and it seems ok, same interface so why not. Going from the iPhone charger to iPad though I don’t think will work, too little power.
Dont charge it with the iPad charger it can damage your battery.
I have charged my i-phone 3g with i-pad charger and strange thing happen. The Bat display shows charging but when i disconnect after all night charging the bat level shows low, one time i restarted the phone then it showed the correct charge level.even Apple has bugs!
Does it matter if its powered down or left on
