Charge mobile faster with short USB cables

How to Charge mobile faster

Recently I came across with an nice android app called "Ampere".
Yes, it displays the current flowing into your mobile i.e while charging and also the amount of current being consumed by your smartphone while discharging.
With this app running on my mobile, I ran an small experiment.


Here are my observations,

Scenario	Charging or Not	Min Current	Max Current
Laptop - USB long cable	Laptop charging	770mA	840mA
Laptop - USB long cable	On battery	750mA	780mA
Laptop - USB Short Cable	On battery	1150mA	1180mA
Laptop - USB Short Cable	Laptop charging	1150mA	1180mA

The same goes when charging using the chargers.

With long USB cable the charging current was 890mA and with short USB cable it was 1460mA.

Charger rating was Input--0.6A, Output -- 6V- 2000mA

Its clearly seen,there is difference of 400mA  and that's a bummer if you use long USB cable.

It can be easily concluded from above table as well that using Short USB cable to charge will definitely decrease the  charging time i.e will charge your mobile or another device quicker.

And also, it does not  matter whether your laptop is charging or not the power being drawn from the USB port of laptop remains almost same.

You can also download the app from here Ampere Android app
and can understand how fast your mobile is charging with the cable you have or do you need to replace your usb charging cable.
