Faced with a low battery warning right before you need to leave? These neat tricks can help you charge your smartphone faster than usual.
Put it into airplane mode
The less your phone is trying do while it’s charging, the more quickly it will recharge. Airplane mode blocks any wireless radios on your device, reducing your phone’s capabilities and therefore stopping it from doing so much.
It won’t receive calls or messages while it’s in airplane mode, but it’s worth it to have a device that will stay on for the next few hours.
Use The Right Power Adapter and Cable
This can’t be stressed enough. All gadgets work with different chargers, so the power adapter that comes with your smartphone is what you need to charge your device. Ryan’s explained how chargers work in detail, so I’m going to stick to just what you need to know: pay attention to the amp rating. Your charger will have something like this written on it: 5.0V->1A. That 1 amp of current is what most smartphones need. If the charger has a higher amperage rating, don’t worry — your phone will still charge, but at a faster rate. If the rating is lower than 1A, then your phone will charge slower than it probably should. Note that this isn’t a hard-and-fast rule, but is true for most smartphones released in the last year.
Turn it off
Turning your phone off completely will allow it to recharge even faster than putting it in airplane mode. Again, you might miss out on a few notifications while it is off, but you’ll have to live with that if you want your phone to last until you come home again.
