Smartphone charging – Things you need to know

These days we have a number of smartphones in our house and that means a lot of smartphone charging (chargers and cables).


We also have different types of charging like quick charging, fast charging, adaptive fast charging, flash charging, dash charging, turbo charging, rapid charging, vooc charging, etc.

So, which charger to use? Which cable to use? Does it really matter?

Some general things you might know about smartphone charging:

  • Use original charger and not duplicate ones. Because using duplicate chargers can damage your phone or maybe your phone’s entire electrical system, you never know.

Things you need to know about Smartphone charging

  • If your smartphone supports any types of quick charging as mentioned above, use a quick charger, if in case it is not provided in the box, buy a third-party charger from a renowned brand.

All these things are fine because most of the people use good chargers, but what about cables? Nobody pays attention to it.

All people do is check if it is micro USB, type- C or lightning, that’s it. But do you know that cables play an important role in charging? I’m not talking about the old days when there used to Nokia’s fat and thin pin charger cables. Even if your charger is of good quality, original, but if your cable isn’t good, it will slow down your charging speeds. If you’re curious about it, go check it yourself by using different cables. There will be definitely a difference. Do you know why it happens?

The main principle behind it is basic physics. You might have heard the term “Resistance”.

Resistance in any material depends on certain factors like:

  1. Thickness
  2. Quality of the material
  3. Length
  4. Temperature

If you notice the cables which are available in the local market, they are thin cables and their quality is also low, the amount of metal (Copper wire) used in it is very less because it’s cheaper, making it highly resistive.

What happens here is, the charger is sending a lot of currents, but it doesn’t reach your smartphone completely because somewhere in the middle there is so much electricity that drops.

For example: Take an example of a pipe. If the pipe’s diameter is thick it can discharge water more when compared to pipes with lesser diameter, keeping in mind the discharge from the tap is constant for both the cases.

The Same thing holds good here. If your cable is thick it can carry more current with it.

If you see One plus 3 smartphones, its cable is very thick because it has to carry a lot of current i.e. 4 amperes. If in case you use dash charger which transits 4 amperes with normal thin USB cable, then your phone will not get dash charging (quick charging) benefits.

So, this is important. Use a good charger with good cable, recommended to use original, if not use some renowned brands. This will solve all your problems of slow charging.

Some of the charging habits you need to follow:

  • Never charge more than 2-3 times a day (using the phone for 30 min and charging for 30min stresses your battery).
  • Try not to drain whole battery (never use it till it gets to 0% it stresses your battery, try not to decrease battery percentage below 20%)
  • And the last don’t charge your phone while using it (never).
