Constantly tethered to a wall, trying to give your iPhone extra juice?
Here are some tricks that will speed up the charging process.
If you plug an iPhone 6 Plus into a regular wall charger and wait five minutes, you'll likely see a 3% or so increase in battery life. Good news: There's a way to double that.
First, put your iPhone in Airplane mode. Your iPhone won't waste energy on notifications, texts, or searching for a signal.
Next, take off your iPhone's case.
Batteries in the iPhone don't do well in heat, and your case could be generating excess heat, according to Apple's website.
Also, use an iPad charger instead of the one that comes with your iPhone.
The larger adapter charged an iPhone 6 Plus 40% faster than a smaller one when we put it to the test.
Lastly, leave your phone alone while it's charging. When the display screen is on, it eats up your battery.
If you do all those things, your iPhone should double the amount charged from about 3% to 6% in five minutes.
