To that end, a test from a completely dead iPhone to fully charged might have been a tad more instructive, but this should still provide a rough framework for what to expect when charging in a hurry. There is an argument to be had for the iPhone's battery strength indicator not being 100 percent accurate. Was this the most scientific of testing environments? Not quite. Still, if you're pressed for time and need to charge up as quickly as possible, you might want to resort to Airplane Mode just to ensure that your device doesn't begin updating apps in the background or processing, say, a video sent to you via iMessage. Technically, sure, but the difference isn't exactly earth-shattering. So does Airplane Mode help you charge faster?

I was able to get a 95 percent charge in one hour 29 minutes. With Airplane Mode activated, I was able to get to a 25 percent charge in 18 minutes and a 50 percent charge in about 43 minutes. Needless to say, my expectations where high. Now it was time to try it with Airplane Mode enabled. Be aware that a hard reset will erase all your data and downloaded apps. If it still doesn't charge when on then try a factory restore (also known as a hard reset), using the phone's factory restore feature and then check if it charges OK when it is on. The problem may be rooted in the charger but its also possible that the phone. To get out of safe mode simply turn off the phone in the normal manner and turn it on again. If the phone gets hot while charging, disconnect it from the charger. Getting to a 95 percent charge took one hour and 32 minutes. A cell phone that shuts off while plugged into the charger will not recharge. Avoid using apps that require a lot of processor or video power for long periods of time. If the phone is already off and then you plug it in to recharge, the phone may turn on and you. IF you turn the phone off after you plug into charge, you may see no signs of charging at all. There is no need to power down when you charge, but it will not hurt anything if you do so. Reaching a 50 percent charge took 45 minutes. A: Answer: A: Yes, you can charge your phone with the power off. With Airplane Mode turned off, I was able to charge from 1 percent to 25 percent charge in 21 minutes. Here's what I found using an iPhone 5s as my testing device with all charging being done via a wall socket. Intrigued, and perpetually in need of a charge, I decided to check out this oft-cited iPhone lifehack for myself. After all, with GPS lying dormant and all of the wireless radios inside the device rendered temporarily inactive, your phone can take a break from things like searching for a cellular signal and work on recharging. On the surface, this makes a whole lot of sense.

A widely circulated iPhone tip would have you believe that your device will charge must faster in Airplane Mode.
