Why is the phone charged only when it is off? Reasons and solution of the problem

There are different reasons, because of which the phone is charged only in the off state. And this is a problem, because a modern gadget requires a lot of battery power, consumes a lot of energy, and sometimes you have to charge it during use, watching a movie, playing games, etc. It's extremely inconvenient to do this only in the off state, because this way the device most of the time Is trivial inaccessible.

And in general, it's unusual to charge the phone only when it's turned off. But it is worth noting that for some models of tablets and smartphones is the norm, which is provided by the developer. Although this is stupid, it is so. But more often, if the phone Meizu is charged only when it is off (this applies to other brands, but on the forums people often use it with Meizu smartphones), then this is a software or hardware problem. Let's understand why this happens.

The phone is charged only when it is turned off due to the firmware

The very first and common version is firmware. This is especially common in Chinese smartphones: ZTE, Meizu, Xiaomi, etc. These phones are sold on the basis of the Chinese shell, and there is no native cracker for it. Therefore, users often install third-party software - unofficial firmware.

It is logical that such firmware developed by amateur programmers and installed by the user without such skills, can brake. And the problems can be very diverse: a weak range of brightness control, strong heating in the passive mode of operation, rapid discharge of the battery, conflict with the charger. It is worth noting that it is because of bad firmware and software problems that something like this happens most often. With hardware this can also be connected, but extremely rare.

You can fix the problem of firmware. For this you just need to return to the official version. The phones have the appropriate functionality. If not, the service center will help. But you can even try to put a new unofficial firmware, which, judging by the reviews, works well and does not fail. It is possible that it is your current global firmware that works poorly and causes a conflict between the charger and the gadget itself. In this case, it is not necessary to be surprised why the phone charges only when it is turned off.

Defective power supply or battery

It is logical to look for the cause in the power supply - it can also cause. It is easy to check whether the power supply works correctly. To do this, try using it to charge another tablet or smartphone. If everything goes well, then the problem is not in the power supply. You can also try to charge a problem smartphone using a laptop or computer by connecting it via USB. If the charging process is activated when the phone is on, it is worth looking for a problem in the power supply.

There is also another rare reason - low voltage in the network. If it falls below 220 V, some phones and tablets may not be charged when it is on. Sometimes the power supply is so weak that it just does not have time to renew the charge of the phone when it is running. This concerns third-party universal charge, so the best way is to charge the phone with "native" devices.

It is possible that the problem may be in the battery itself. To check it, you need to find the same one and try to charge the phone with it. If it works, then the problem is clearly in the battery, which means that it needs to be changed.

Oxidation or contamination on contacts

Contacts can also be the reason for charging the phone only when it is turned off. We recommend that you use alcohol-impregnated cotton wool on the contacts on the phone and the charger. It can be in them. Unfortunately, this method helps very rarely, but there is always hope.

Other problems

Sometimes it is impossible to find out, because of what the phone is charged only when it is turned off. Even specialists can not always answer. The reasons can be anywhere. For example, in the feeding scheme, a microcrack could occur during fall. Also, a micro-fracture could occur inside the cable. Determine all this at home is impossible, and sometimes it does not work even in workshops.

But if you can not solve the charging problem , then you should not be upset. In itself, it is insignificant. The main thing is that the smartphone works fine and performs its functions. All the same, most users put phones on charge only in the evening, when they themselves go to bed. And it's not necessary to charge it during the day. So sometimes you just have to accept and not pay attention to such trifles.

Which phones are at risk?

This problem is not rare. Many users have such situations. Chinese cheap smartphones often work in a similar way. However, on the forums you can find messages that both Russian Explay phones are charged only in the off state, but this does not apply to the whole line of the manufacturer or even to all models. It just happens, not only with cheap Chinese state employees, but also with expensive flagships.
