Do you have a smartphone that does not charge? We show you how to solve it

Has your smartphone said enough and does not want to recharge its battery? The problem can occur for a number of reasons, causing do not charge at all or charge very slowly. It's a pretty common problem actually, but some of the solutions are pretty straightforward and can be used by any user. We show you some of the most common.

Fix the USB port

One of the most successful solutions is to perform a repair by yourself. One of the most common problems occurs when the interior of the USB port and the microUSB do not make good contact, either due to a manufacturing defect or due to their continued use. What you need to do is turn off the device, remove the battery and use a thin and small piece to "lift" the metal plate inside the smartphone port, yes, carefully.

Change the cables

One of the components that suffer the most in chargers is the USB cable. If it is not welded to the charger itself, one of the options that we can take into account is change the cable and check if it actually works or not. Thus, we can rule out that it is a device problem (or not).

Clean and take care of the charger

Sometimes the problem may be due to the port being dirty or wet, either from carrying the smartphone in your pocket or leaving the charger plugged into a wall “attached” to a terrace or something similar, where it absorbs more moisture. To avoid it, check before connecting the cable to the phone that all ports are clean and free of any impurities. In addition, it is advisable to avoid overcharging the device since the smartphone can be charged in just 2 or 3 hours.

Change the battery

If you've tried all of the above and something's still not working, maybe the best option is to buy a new battery. As we already know, these have different charging cycles and, in addition, they can deform or be damaged by high temperatures, which causes failures in the smartphone and when charging. If indeed you battery is damagedAlways opt for an original battery, although we can always use “third-party” batteries, although they offer us a lesser guarantee.

Is the charger you are using correct?

Normally all devices, whether smartphone, tablet or headset, have a microUSB connection, so we usually decide to use the same charger for all. The problem with this decision is that the amperage of the battery is different in each case, so the charger may not be enough - or too powerful- for any of them. This also includes charging through the computer's USB port, much slower than a wall socket.

Calibrate the battery

If you've ever had a sudden battery drain (for example, go from 20% to 5% in just two minutes), you will most likely need to calibrate the battery. For this we will have to perform a wipe through a CWM or TWRP type recovery.

We hope that this series of tips has helped you bring your smartphone back to life or, at least, has increased its useful life after just one charge.
