The Mystery Behind Slow Charging Of Smartphones

We have now entered in an era where we have different types of technologies for charging for smartphones like OnePlus' Dash Charging, Qualcomm's Quick Charging and Motorola's Turbo Charging. All these technologies are aimed at increasing the charging rate. If you wonder why your phone charges slow, read on.

Firstly, the main thing which matters is the type of charger you use. Charging speeds depend upon the amount of current that the charger gives to the wire. If you use a fast charger or dash charger, you will experience high charging speeds because high amount of current is being supplied to the wire by the charger.

Note: Even if you use a fast charger and if your device doesn't support fast charging, you will not experience high charging speeds.

Secondly, the type of wire you use. Charger and it's wire are related to each other. The thicker the wire, the higher is the amount is the amount of current carried by the wire supplied it. If you use low quality charging wires which are very thin in use and cost cheap, the amount of current carried is very low. Let me explain you this with an example.
If water flows through a thin pipe the space for it to move will be very less.
One the other hand, if water flows through a thick pipe under same pressure as the first one the space for it to move will be much more than the first one and it will move faster.

Charging speeds are also affected if you use your phone while it's being charged. I think it's not hard to understand that when you are using your phone, a part of the charging current is consumed to fulfill your power requirements when the device is being used. One of the major misconceptions I have come across here is that the phone sucks power from the battery while it's being charged. That's not the case at all. Your phone instead uses the current being supplied from the connected charger to fulfill your usage's power requirements. So, the lesser you use your phone while it's being charged, the faster it will get charged. If you wish to increase your device's charging speed, you can consider switching to airplane mode or switching off your device and letting it charge.

If you are a rooted user, you can use a custom kernel to increase the charging speeds. Many kernels these days allow you to tweak the current inflow, so using this option you can either increase the charging speeds or decrease the current input so that when you are using your device while charging it doesn't get hot.

So I hope I was able to answer all your queries regarding slow charging speeds in this post. If any doubt still persists, please put it down in the comments box below and I will get back to you as soon as I can.
