￼HOW TO IDENTIFY ORIGINAL CHARGER FOR YOUR SMARTPHONE
If you are in Nigeria, you would notice that there are lots of fake phone accessories in the market. In this post, I would explain to you how you can test or identify an original charger meant for your phone.
I have been a victim of wasting lots of money on so-called original chargers. It’s either the charger is very slow or it ends up spoiling within a few days of using it.
Identifying an original charger is not difficult at all once you have the right knowledge and App on your phone.
First of all, to identify the original charger for your smartphone, you need to know the right charging specifications for your device. We are only going to focus on output specifications because that’s what charges your phone.
It’s usually written on the charger that came with the phone. Most smartphones use 5V/1-2A Output charger. The 5V means 5 volts – it is the driving force of the current entering your phone from the charger.
The 1A or 2A represents the Amperes. It’s the rate at which electric charges are flowing out of the charger. So the larger the amperes, the faster the charging ability of the charger, but please do not increase the original charging amperes of your phone by more than 20%.
The easiest way to spoil your phone is to use a charger with a higher voltage than the charging voltage allowed by your phone. If your phone is 5V, and you use 9V, that would spoil your phone immediately. It’s like throwing food at a dog more than it can swallow at a time. This happens when you do not know how to identify original charger for your smartphone.
If your phone charging Amperes is say, 1.5A, using 2A won’t cause any damage, as long as the voltage is correct. But using 3A is an overkill and could also damage your phone with time. This also means you do not know how to identify original charger for your smartphone.
Now how do we know that the output written on the charger is correct?
Luckily, there is a component of the Android OS that measures the current entering the phone, and there is an application on Google play store that measures the current entering the phone. The application is called “Ampere” and can be downloaded free of charge.
Download and install the application on your smartphone. Once you get to the market to get a new charger, open the application and start testing the charger with it. This application would enable you to identify the original charger for your smartphone.
This application called Ampere would show you the charging current (measured in Amperes) entering your phone after 10seconds and would continue to calculate it with time. If your phone battery capacity is between 1800mAh to 3000mAh, and the charging current produced by the charger is between 800mA to 920mA, then the charger is potentially good for your phone.
But if after a minute or two of measuring the charging current, Ampere detects that it drops to 650mA, then there can be two conclusions. It’s either the charger is not so good for your phone or your phone battery life has reduced (that is, your phone battery capacity has reduced).
If your battery capacity is from 3000mAh to 6000mAh, the charging current for it would usually be above 1100mA to about 2300mA. If that is what Ampere is measured, then you are good to go, but if it’s less than that, the charger is either not good for your phone or your phone battery capacity has reduced.
Now that we know how to identify original charger for your smartphone, let’s move on.
Please Note: It is very important that you set the right measurement method and measurement interface of the ampere application so that the right measurements are being taken by the application. If you notice that the measured current is abnormally low, change the settings of the ampere application until you start getting the measurements described above.
Additional Tip: Most original chargers are usually sturdier in shape and a bit heavier than the fake chargers – you can use that to guide you too.
There are some charges that usually spark every time you plug them in. Those are bad chargers. To know if it sparks, leaves your phone plugged in and insert the charger into the power supply, if it sparks it means the charger is bad.
This method is just to test the electrical resistance of the charger to see if it can withstand sudden electrical surgery. Please note that normally, you aren’t meant to leave your charger plugged into your phone while inserting the charger into the power source. This again helps us to know how to identify original charger for your smartphone.
