How to charge your Smartphone faster and more quickly than usual?

Never charge you phone with a long cable. Normally what people tend to do is using their mobile when connected to charger and sleeping in bed. But as the wall is far away for connecting the charger they buy a long cable. Don’t. Long cables have more resistance than the short one. So longer the cable the more time it takes to charge your phone. When you buy a phone you get an original cable of that phone which is around 1m, if your cable is broken then just buy the same one.

Switch to Aeroplane Mode or Switch off the Phone Completely

Easy and highly recommended way you could do to charge your smartphone faster is to put the phone in flight mode while charging. Even better way is completely shut down your smartphone. The power supply from your wall should be providing as much as current as the charger needs to charge the battery plus the current at which the phone operates. So if your mobile is turned off then the charger only charges the battery and as the phone is turned off it does not need the extra power to operate the phone.

Turn off unnecessary features

If you are waiting for important calls or message then you should switch off unnecessary features. If you don’t have LTE connections just switch off the LTE connections and connect to 3G otherwise it will constantly search for LTE connections and drain your battery fast. This also helps the battery to long last during the use.

If you have an iPhone, buy an iPad’s charger, it will charge your phone faster. Output of iPhone charger is 5V and 1Amps whereas iPad charger’s output is 5.1V and 2.1 amps.

USB

If you want to charge from Computer’s USB port which is usually not recommended because it charges the phone slowly than you should probably charge in USB 3.0.  In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A) moreover in USB 3.0, it moves up to 900mA (0.9A). The charging downstream and dedicated charging ports provide up to 1500mA (1.5A).

In theory if you want to charge your phone faster you should provide high current to the phone so you need a high current charger. You need not only a high current charger, but need a high current charger that will be recognized by the phone(Dangerous!!! If you are not professional don’t try this at home). All USB devices are designed to work at 5V of voltage so be sure at high current there is no more than 5V.

You could also try short-circuiting the USB data pins on the phone side connection.  It draws the max amount of current without needing any digital negotiation (otherwise it would negotiate with the OS and only get 500mA).

From Wikipedia

on a dedicated charging port, the D+ and D− pins are shorted with a resistance not exceeding 200 ohms … A dedicated charge port may have a rated current between 500 and 1,500 mA

Buy an extra battery so if you are in hurry and don’t have time to charge you could just swap the battery. If you can’t swap your battery then just buy a power bank, you could charge in the go. The rest of us will just have to wait for Future Batteries.
