Have you noticed lately that your smartphone battery is charging slower and slower? Here are 5 reasons why your device is charging slowly
If your smartphone is not very young anymore then the charging time might seem endless. It happens to everyone, with all models of smartphones (and tablets, laptops and other battery-powered electronic devices), of all brands. And there are more than one reason for slow charging.
At least five, which becomes six if we add the "seasonal" cause of high temperatures that slow charging. Unfortunately, by the way, these causes of slow recharging are rarely isolated from each other and, on the contrary, very often we experience at least two or three simultaneously. In some cases, fortunately, it is possible to remedy and get a fast smartphone charging but in many others, unfortunately, there is nothing to do but change the smartphone or our way of using it. Here are the top 5 reasons why your smartphone recharges very slowly.
If you're tired of your slow smartphone and want to change it, consider buying with a mobile provider that offers cell phones on installment:
The charging cable
The USB charging cable is the most abused accessory by every smartphone owner: bent, braided, pulled, left out in the heat and cold. Each of these operations often creates micro injuries to the cable that, in the long run, drastically reduce its ability to carry electricity to the battery of the device to which the cable is connected. If we want to change the cable and buy one to solve the problem, however, we must pay attention to the quality: a good cable is made of copper, which conducts electricity better than other metals such as aluminum with which are made the cheap USB cables.
The source of charging
If the cable is ok, but the smartphone is charging slowly, then we must go to see where the electricity carried by the cable comes from. If the smartphone is connected to a laptop, for example, it's almost certain that it will receive little energy from the USB port: if not, we'd risk dumping the computer to charge the phone or, worse, frying the USB port. If we use Qi wireless chargers then the charging may be even slower because this standard is very comfortable to use but still can't transfer much energy in a short time.
If the smartphone is connected to a classic wall charger and charging is very slow then we need to make sure we are using the right charger for our device. It's not uncommon to have more than one charger at home (perhaps the legacy of old smartphones) and use one at random to charge your cell phone. The problem is that not all chargers are the same: there are more powerful ones and less powerful ones (usually older ones). From the power depends the charging speed, as long as the smartphone supports the maximum wattage of the charger.
The smartphone battery
If the smartphone is old, the reason for the slow charging is almost certainly the battery itself. Over time, the lithium-ion cells that make up the batteries degrade, with two negative effects: the maximum charge that the battery can store goes down and charging times go up. Also the chip that regulates the energy input in the battery, to avoid overheating and dangerous electric discharges, could start to give some problems with age.
Don't use your smartphone while charging
Finally, the last reason why your smartphone doesn't charge quickly could be you: if you keep using your cell phone while it is charging most of the energy that enters the battery is immediately used to keep the device on and active. There's little you can do about it: if you need the battery charged in a short time, then you need to stop using the device while charging it.
