You’re probably already aware of the fact that your phone runs off of a battery. You need to charge that battery quite frequently in order to make your phone work properly. Without it, that device wouldn’t do anything at all, much like all of the electronics in your home that aren’t plugged into walls. However, did you know that you can improve the battery life of the one in your mobile phone, just by using a shunt resistor? These devices are designed to measure current, and if you keep on the current in your phone’s battery, it will work much better. Here’s how you can do this, courtesy of Canadian Shunts.

Understanding How Shunts Work

The first thing that anyone from Canadian Shunts will tell you is that you need to know how a shunt works before you can measure anything with it. Many of these devices are used to measure DC (direct current) or AC (alternating current). The battery in your smartphone produces a current (many flowing electrons that hold electricity) in order to make the phone work. In order to measure this electrical current, you need to have a shunt that consists of two bits of metal (with comfortable plastic handles on them to prevent you from getting shocked) that are connected to a measuring device by several wires. You hold the metal bits to whatever you’re measuring, which in this case would be your phone battery, in two different places, and then turn the shunt device on. It will give you a measurement of how much current is flowing through it. From there, you can determine whether or not the battery needs more charge, or if it’s fully charged.

Why Would You Need to do This?

This is a very common question. After all, your battery comes with a charger that lets you know when it’s full, right? Why would you need to use a shunt? Well, a shunt is much more technologically advanced than a simple charger. When you plug your phone into the charger, it automatically starts charging that battery, regardless of how full it is. This can cause problems with the battery, as your charger isn’t smart enough to know that it’s potentially damaging it. For example, an overcharged battery can overheat, which can lead to a serious breakdown within the device, rendering it useless. On top of this, constantly charging a battery that isn’t completely empty can harm it by making its lifespan shorter. Each time that you charge it unnecessarily, you’re actually damaging it. When you use a shunt to check the charge, you’re actually determining whether or not it needs to be charged. If it doesn’t, then the solution is obvious – don’t charge it. But if it does, then you can plug the device into the wall. The precision of the shunt is what matters here. The better a handle that you have on the current in that battery, the more accurate your charging process will be, and the longer that battery will last.
