If your device is
low battery and you only have a limited amount of time to charge it, here’s a
quick tip for you.
These tips should
work for practically anything that charges via USB, including cameras,
peripherals, and any other device you might have.
Don’t use your Computer’s USB Ports for charging
You can connect
your tablets or smartphones on your computer usb cable and they’ll charge. But
they won’t charge as fast as they would if they are using their dedicated
charger.
In other case, you can use any USB charger
with any phone or tablet, but if there isn't sufficient power available you may
find your device won't charge - this is often the case with iPads, which will not
charge from a PC's standard USB port.
In the USB 1.0 and
2.0 specifications, a standard USB port is capable of delivering up to
0.5A. USB 3.0 increases this to 0.9A on typical ports, while a dedicated
charging port can offer up to 1.5A. USB 3.1, which is intertwined with (but not
the same as) the new USB Type-C standard, supports up to 3A. USB charging
is fairly standardized you should be able to plug any device into any USB
charger and nothing will explode or catch fire. Instead, the device just
draws as much power as it can from the charger. A high-power USB port
on a recent computer may be good enough depending on your device, but it’s
better to rely on a dedicated charger if you’re in a hurry
·
Check your phone
or tablet’s specifications to see what it’s capable of drawing. Skip your
computer’s USB port and plug your phone or tablet into a dedicated
charger.
Use other Charger that is more powerful
You can sometimes charge your device faster by upgrading to a more powerful charger. For example, Apple’s iPhone 6 phones ship with a 1A (5W) charger, but they can charge faster when plugged into Apple’s 2.1A (12W) iPad charger. If you want to charge your iPhone 6 faster, plug it into an iPad charger instead of its normal charger.
Use a Good USB Cable
Not all USB cables
are the same. For best results, use the cable that came with the device. Cheap USB cables you buy afterwards can’t necessarily transmit the full
amount of power, and may charge your phone or tablet much slower.
Leave your Phone Charging
This one may seem
obvious, but it’s true. If you’re waiting for your phone to charge and playing
a game on it, that game will cause your phone to consume more power and slow down
the charging process.
Some people
recommend shutting down your put entirely, which could help a little bit in an
emergency — but it is not necessary if you want to stay connected.
Or, if you’ll be
driving somewhere in your car, get a universal car charger and
charge your phone or tablet while driving.
Qualcomm feature
Some modern
devices support “Quick Charge,” which is actually a Qualcomm feature. Quick Charge allows
a phone or tablet to charge much more quickly from empty, slowing down
when the battery becomes more full. This could allow you to get above 50%
battery capacity in half an hour. To use this, you’ll need a device with Quick
Charge technology built in and a dedicated Quick Charge charger, which may not
actually be included with your phone or tablet, but may be a separate accessory.
