If your battery does not charge as it should, do not immediately assume that your charger has deteriorated or the battery has become bad. Based on personal experience, the problem in this case (and the solution) can be much simpler than you think. If your phone or tablet does not charge properly or does not charge at all, we will tell you about 10 ways to repair a phone that has problems with charging.
How to repair a phone that is not charging properly
Why the phone does not charge
This problem can occur for various reasons. Either your phone does not charge at all when it is connected to the charger, or it charges very slowly (sometimes a little faster than the discharge process). In principle, this is a very common flaw, and we ourselves have encountered this. Below we provide a list of possible solutions.
Most charging problems are related to your USB cable, or to a charger, or even to a USB port.
Repair your USB port yourself
The fastest, easiest and most successful solution will be a small soldering on your working device. The problem is that often the metal surfaces inside the USB port and microUSB charger do not give good contact either due to a manufacturing defect or due to the constant connection and disconnection of the charging cable.
All you need to do is turn off your device, remove the battery from it (if possible) and use a small object, such as a toothpick, to lift up a small plate inside the USB port of your smartphone or tablet. Do it very carefully and gently. After that, you need to reinsert the battery again and connect your device to the charger. In 9 out of 10 cases, this method gives a positive result.
Check the plate inside the USB port of your device. the cable may not provide normal contact.
Remove lint, dust and sweets.
Do you carry your phone in your jeans pocket? If so, then in this case the different pile will be the culprit: we have already lost track of the many cases when the pile from your Levis turned out to be the cause of poor USB charging.
We also saw phones whose charging ports were clogged with chocolate: in such cases, the phone was placed in a bag next to a package of sweets. A can of compressed air will help to purge foreign elements, and your USB-connection will return to normal.
Some ports are larger than others and because of this, various garbage accumulates in them. Remove such trash away.
The most unreliable element of the charger is its cable, not the adapter that plugs into the outlet. In this situation, users of Apple products are particularly vulnerable, since the normal life of expensive branded Lightning cables, in all probability, is no more than 15 minutes. Many cables are operated very rigidly, and endless bends and twists make themselves felt.
Replacing the USB cable that came with your phone with any other is another aspect for a negative charging experience. The easiest way to identify a faulty cable is to replace it with another one, followed by checking how it works with your device. If everything is in order with such a cable, then it is time to purchase a new cable, and if not, then something else will be the culprit.
Cables are easily damaged. Apple Lightning. especially.
Suspicious Adapter Diagnostics
If the cable does not cause a suspicion that it may be the cause of the problem, then it is worth checking the adapter plugged into the outlet (especially one in which the charging cable can be disconnected). We faced problems with numerous chargers, in which, as a result of frequent shutdowns and connections, the USB port was slightly loosened.
We also recommend that you make sure that the same “adapter-cable” combination works on different devices. this can help you eliminate the possibility that the fault lies with your device, and not with the cable or adapter. In addition, it would not hurt you to check the operability of the outlet, that is, if there is any malfunction in it.
Make sure there is no problem with your adapter.
Our advice to you: do not charge your phone near water or in excessively hot or humid conditions. Also, you should not charge your device in excess of the norm; charging the phone all night, while he needs no more than two to three hours for this, is not a good idea. This could cause the battery to explode or damage your phone.
Despite the fact that your device has a built-in charge controller for your battery, sometimes it does not work (you may remember the stories about exploding batteries that took place in 2013). Better to be safe than sorry. Or burn to the ground.
If you change the charger or cable, be careful: the Internet is full of messages about cheap third-party chargers that exploded in the middle of the night or over-fry smartphones. As with any other electrical equipment, make sure that everything you buy meets certain safety standards.
Replace the battery
The battery life, alas, is not eternal, and after a few years it is already difficult for them to hold a full charge. The more often you charge and discharge them, the faster they will have to be replaced. If your battery began to “die” after 6 months, then it is probably just faulty, and you should make a warranty claim for a free exchange for a new battery. But if he is already 2-3 years old, then in this case the life of such a battery is coming to an end.
Note that some faulty batteries are very easy to identify, as they begin to swell or leak electrolyte. If you don’t see anything like this from the outside, then you need to remove the back cover of the device and inspect the battery (unless, of course, you succeed. some devices come with sealed battery compartments).
If the back cover of the device does not open, we recommend that you put such a device face up and twist it around its axis. A swollen battery deforms the back cover. you may not see the swelling place on the battery, but this will be enough to make the device spin. If you suspect that your battery is swollen or leaking, remove it or return your phone to a service center and buy a good replacement for such a battery.
If you intend to replace the battery, try to purchase a branded one.
Different chargers charge differently
As a rule, charging from an electrical outlet is always faster than from a computer or laptop, since computer USB ports are designed for low current. A power outlet can produce twice as much current as a USB port, and in the case of so-called fast chargers, even 5 times as much. This indicates that charging is much faster. If your phone is slowly charging, and from a laptop. this is the essence of the problem.
If your charger does not work too well, in your opinion, try something else that fits your device. A charger from another phone will not always be able to give the necessary voltage and current strength. for example, a charger for a Bluetooth device will be less powerful than one that is designed specifically for charging smartphones. In the case of new premium phones, it must be a phone that supports the fast charge function, although the charger of this phone is not a fast charger. We advise you to read the information on this topic, printed in small print in documents for such phones.
Your desktop PC or laptop will not be able to charge your Android device as fast as a wall outlet.
Update or roll back
Software updates and new versions of Android can cause some damage to the life of your battery, especially when the old device is updated to the current software. New devices are often optimized to take advantage of the latest software, with pre-optimized hardware and software on board, while your 2-year-old device is experiencing certain problems when receiving an update.
If this happens to you, and you cannot get rid of such a problem, then you should roll back your device to an earlier version of Android. But remember that this is associated with great risks. To protect your device, the latest software versions are highly recommended, although it is worth noting that the risks associated with leaving the old working version on your device are often negligible.
Similarly, sometimes the battery life of your device can be significantly increased due to a certain update, so if you think that with your old Android software you are falling behind, you should go to the “Settings” section and open the “About device” item »To check for updates.
Update your version of Android regularly (or roll back to a previous version if you really need to).
Disconnect your mobile device
When various applications or functions use the battery heavily while it is charging, this affects the time it takes to reduce the battery life. If you charge the device while communicating with someone on Skype at 100 percent brightness of the display, it’s natural that such a device will require a longer period of charging than when the screen is off and Wi-Fi and 4G are turned off.
If you want your battery to charge as fast as possible, switch (or turn off, respectively) the flight mode. Imagine that your device is immersed in a kind of energy sleep. Or fueled by a Red Bull energy drink, in the dark.
Calibrate your battery
Sometimes, what your device “thinks” about your battery may be different from what is actually happening. The effect in this case is that your phone may function differently based on an estimate of the remaining charge in the battery, including a performance limit, before the charge level drops to just 2 percent.
Not so long ago we published a detailed guide on how to calibrate the battery, so we won’t post the information again, we’ll just say that this is a very useful option, which is worth a try before you say goodbye to your “dead” battery forever.
Calibrating the battery can be another effective way to fix charging problems.
If all else fails, then you need to double-check that you have really turned on the power saving mode. This is the first thing you will be asked about at the device manufacturer’s office if you call there for help. By the way, this may be the next step for you if none of the methods described above helped you.
