Mobile phone chargers vary from phone to phone and are not all interchangeable.
These days, it’s common to hear statements like “my phone’s battery isn’t lasting as long as it used to, “I charged it all night, and it’s already dead,” or “my phone charger keeps hanging, and I have to take the battery out.”
If your phone’s battery is acting up, consider the following: Are you utilising the charger that came in the box with the phone? Have you purchased a replacement charger? Are you charging your phone with a different manufacturer’s charger even though it doesn’t belong to that brand? At the light, did you purchase one of those car chargers?
Nowadays, most phones have the same MicroUSB, USB Type C, or Lightning connector, wireless mobile charger, so any charger should work. Since it fits, we assume it must be okay. You might not be aware, though, that not only could you harm your phone, but you might also cause enough damage to void the warranty!
The attempt by manufacturers to adopt the MicroUSB charger design as the charging port as a standard is the root of this problem. Since any charger can be used, there will be less e-waste, which is good for the environment because fewer people will discard their old chargers. Although the physical design of the MicroUSB was adopted, not all chargers use the same circuit paths.
In other words, although the chargers themselves are different, the connectors are the same size. This means that even though the connector fits, you shouldn’t use any charger.
The stages of the charging:
There are four stages that the battery passes through to charge.
1: As soon as you plug in your phone, the battery’s voltage rises quickly.
2: The voltage peaks and the charger’s current starts to decline.
- When the battery is fully charged, and the charger completely cuts off the current to the phone.
4: Standby mode, which only provides a top-up charge when the battery falls below a predetermined voltage.
Your charger must comprehend these stages and be able to modify them as necessary.
What to watch out for is listed below:
The wall charger is designed to take the standard current and reduce it to the level required by your phone. The input levels are listed on a tiny label on the charger itself, which you can see if you look closely. It usually says something like Input: 100-240v, which means that if you plug this charger into the wall in a nation where the standard household voltage ranges from 100 to 240 volts, it won’t blow up.
You must then search for the output voltage. The output of the charger must be higher than 4.2 volts because most cell phone batteries fully charge at around that voltage. A 4.2v battery cannot be charged by a charger that can only deliver 3.0v of output.
The output amperage, which shows the maximum current the charger can deliver to the phone to pull what it needs, is the last thing we need to look at. When using a charger with a 1A output and an android phone that needs 700mA to charge, the phone will only draw up to that amount, so there is no issue. However, if your phone needs 700mA of current but your charger only provides 500mA, a variety of problems, including very sluggish charging, overheating, and complete device failure, may arise.
USB Cables and Chargers:
Even USB charging has its share of problems. Wall chargers that let you connect a USB cable to them so you can charge your phone are very popular. It’s also common practice to simply connect your laptop to any USB cable and allow it to charge your phone. You should be aware that there are currently three different USB specifications: USB 1.0, USB 2.0, and USB 3.0, each of which seems to have its power requirements. For instance, the maximum current in USB 3.0 is 1500mA, compared to 500mA in USB 2.0.
You’ll observe that a USB charger charges your device much more slowly than a wall charger, and this is due to a combination of the quality and thickness of the USB cable, the cable’s design, and the charging source. Some laptops’ USB ports are not powerful enough to power your device, which is why some cables are Y-shaped so you can use the power from both USB ports.
Discharge/Overcharge:
A device must have circuitry that recognises when it is full and automatically shuts off power to the device because you can’t always be there to know when a battery or in-car charger for your phone is full. Many phones do charge very slowly using the USB cable that winds up on itself like dental floss, but the touch screen is unresponsive while it is charging. That obviously can’t be a good thing.
Don’t mix up chargers because different phones require different charging methods, even from the same mobile phone provider. They are specifically made to work with the phone that they were made to charge, certified to charge, too.

Bottom line:
It’s important to use the right phone charger. Not every charging cable, brick, or pad is created equal, especially when it comes to the battery’s long-term health. Use only the charger and USB cable that was supplied with your phone. If your charger isn’t nearby, take a close look at the available charger you’re about to use to make sure it has the power your phone requires. Bring the USB cord that came with your phone with you. It was created and constructed specifically to handle your phone. While it may be tempting to purchase the low-cost, no-name-brand aftermarket chargers, it is better to stick with your charger because doing so literally puts your phone and battery at risk.
