So, at one not the happiest moment, you put your smartphone on charge, but something went wrong. Instead of gratefully winking at you with an indicator and starting to absorb energy, your pet does not show any signs of life. What happened? In this article we will try to figure it out.
1. Remove debris, dust and grains of sand.
If you do not part with your smartphone for a minute, carry it in your jeans pocket and carry it to the sea, sooner or later so much garbage will accumulate in the charging socket of the gadget that it will completely refuse to charge. Therefore, first of all, conduct a visual inspection of the USB port. Then blow it off with a can of compressed air and gently brush it with bristles on a hard toothbrush.
2. Clean the USB port pins against oxidation
Sometimes the device does not charge due to oxidation of the contacts. This happens especially often if the smartphone has not been used for a long time or is operated in adverse climatic conditions. In this case, you can help out by cleaning the contacts with a toothbrush dipped in alcohol, or even a thin needle. Do not forget to turn off the smartphone first and get the battery out of it, and perform the operation as carefully as possible.
3. Replace the cable
The next weak point to check is the USB cable. Their lives are often full of trials and hardships, so it is not surprising that some of them may die without warning. The easiest way to check this malfunction is to take a known working cable from another device and connect it to your gadget. If the problem persists, continue to the next step.
4. Test the power adapter
The charger is also often source of problems. It’s about the very small box that plugs into the outlet. First of all, touch it to check the temperature. Too hot an adapter, as well as too cold, can serve as an indirect sign of failure. Make sure that the cable connection jack is working properly and clean it if necessary. Try to find another power adapter that matches your specifications.
5. Buy a new battery
If you went through all the points and none of them helped you figure out the cause of the problem, then perhaps the whole thing is a software failure. The Android operating system collects statistics on the use of the device in order to prevent a complete discharge of the battery. In some devices, a full discharge leads to malfunctions of the built-in power controller, which, in turn, prevents the device from taking charge as usual. In this case, resetting the device to the factory settings may help (do not forget to back up important data first). Of course, this is an extreme measure and you need to resort to it only if you have already tried everything else.
In this article, I tried to describe the most common problems with charging gadgets and how to solve them. Of course, in real life there can be many more. Write about the cases you have encountered in the comments.
