The battery of a modern phone is a weak link, as the charge is depleted very quickly. The solution to this problem was external high-capacity batteries.

But constant use of such products can lead to their breakdown. In this case, it is advisable to trust the repair of the power bank to an experienced specialist.

Charging rules

External batteries are practically no different from the phone’s built-in batteries. But they are configured to release energy. In order for the system to serve for a long time and reliably, when charging it you should follow several rules:

1. It is advisable to immediately charge new batteries to 100% capacity. After this, the battery is completely discharged 2-3 times and charged again to full.
2. It is not advisable to use a design that has not fully filled the capacity. Experts recommend charging the device until it reaches 100% capacity. Please note that if the indicator shows this value, you should leave it a little longer external battery included. This is necessary because “drip” charging is carried out.
3. Do not completely discharge the battery during operation. It is advisable to start recharging it at 20% capacity.

We repair the battery

Very often these batteries are not charged from the mains, which in turn does not allow it to be used to operate the phone. There are several reasons for this:

1. Damage to the entrance. To determine whether this is the case, you need to disassemble the battery to gain access to internal chips. Then use a multimeter to check if the current is coming from an external source. If this is not the case, you need to completely change the battery charging socket.
2. Complete exhaustion. Very often, users drain the battery to 0%. Therefore, when connecting charger the controller sees this value and just thinks that this device just missing. Decide this problem quite simple. You should remove the internal battery and charge it directly. For this you can use so-called “crabs”, suitable for all types of batteries. When the system has recharged a little, you should insert it inside the case and try charging with it.

Please note that there are many other reasons why an external battery may fail. Therefore, it is better to trust its repair to experienced specialists. They will quickly determine the cause, as well as the need to replace all faulty parts with new ones.

Absolutely all equipment is subject to breakdowns, our favorite ones are no exception. Android smartphone s and tablets! If your Android battery suddenly stops charging, then in this article you will find all the ways to solve this problem!

One of the most common problems with smartphones and tablets is the inability to charge the battery. Many people immediately go to service center to fix the problem, but first you should still solve the problem yourself!

1. Charging cable

The very first problem why the battery may not charge is the charging cable (date cable). If you accidentally pulled it hard, have been using it for quite a long time, or it is a cheap cable, then you should check it first.

2. Charger

If you are one of those who do not remove the charger from the socket after the Android has been charged, then be prepared that sooner or later this charger will become inoperative. It is also worth paying attention to the fact that chargers from different manufacturers may be incompatible, this is due to the difference in current (amps) and output voltage (volts).

3. Contamination and oxidation on contacts

If you do not work in perfectly sterile conditions, and also like to take your Android smartphone or tablet into the bathroom, then you may encounter the fact that the contacts in the device socket may become dirty or oxidized.

Perform a visual inspection and if so, then cleaning must be done. In order to remove dirt and oxidation you will need:

• Spray can with compressed air
• Old toothbrush or thin needle
• Alcohol

Perform cleaning as slowly and carefully as possible, first turn off the device and, if possible, remove the battery (if the design allows).

4. Charging socket

A very common popular problem on cheap smartphones and tablets bad connection charging sockets with the main board of a smartphone or tablet. The socket simply comes off and dangles, as a result of which the gadget does not charge.

5. Old battery

If you have been using your Android for too long, then the breakdown may lie in the fact that the battery has become unusable and there is only one way out of the situation, buying a new battery.

6. Heavy battery discharge

If you have squeezed out absolutely “all the juice” and your Android battery is very discharged, then you may be faced with the problem of being unable to charge it. There can be two development options. The first is to buy a new battery, the second option is to find a fairly powerful charger (a large number of amperes issued) and leave it on charge for a couple of hours. Also, to enhance the effect, you can warm the battery with a hairdryer, then the chance of reviving the battery may be successful. You should be as careful as possible, since all batteries are Li-ion, and lithium is fire and fire hazardous.

7. Charging in the cold

If you try to charge your Android smartphone or tablet at temperatures below 0°C, then you will achieve nothing other than harming the battery. Charge only in a room where the temperature is above +5°C.

8. Software glitch

In Xiaomi Mi Power Bank 2 has Qualcomm Quick Charge 2.0 technology and can be charged at 5V, 9V and 12V. It can also charge itself and charge another gadget at the same time. Protection is installed for excess input voltage, change in polarity at the input, excess current at the output, excess voltage at the output, short circuit at the output, overcharging and overdischarging the battery, exceeding the battery temperature. The powerbank certainly won’t burn your smartphone and won’t burn out on its own under force majeure circumstances. The battery charge level can be understood by the LED indicators. Naturally, for basement offices there is real freedom here in terms of reducing the cost of production. Moreover, the fake will most likely be sold at the same price as the original, or even more expensive. But we’ll talk about the issue of selfishness a little later, but for now here are some tips for buyers Xiaomi Power Bank, so as not to run into a fake.

Additionally, owners are very pleased with the power bank's input and output current strength. To be precise, the device is capable of outputting up to 2.1A, which is great for tablets and smartphones that can take more than the standard 1A. Even the charging input port is rated for currents up to 2A. This is surprising for such a cheap power bank. because there are many expensive batteries on the market that are not capable of taking more than one and a half amperes. In other words, Xiaomi Mi Power Bank 10400 mAh charges quite quickly. According to the manufacturer, this takes about 5.5 hours using a two-amp adapter or about 10 hours with a 1 A adapter.

According to reviews from service center workers, charging problems are one of the most common reasons to contact them. Sometimes this is due to really serious problems, such as a failure of the power controller, which requires replacement of components. But most often, problems with charging the device can be solved yourself. Here is a list of steps, in order of increasing difficulty, that you can do yourself before calling a repair shop.

1. Remove debris, dust and grains of sand

If you don’t part with your smartphone even for a minute, carry it in your jeans pocket and drag it to the sea, then 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 out with a can of compressed air and gently brush it with the bristles of a stiff toothbrush.

2. Clean the USB port contacts from 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 used in unfavorable climatic conditions. In this case, cleaning the contacts with a toothbrush dipped in alcohol or even a thin needle can help you out. Do not forget to first turn off your smartphone and remove the battery from it, and perform the operation itself as carefully as possible.

3. Replace the cable

The next weak link 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 any warning. The easiest way to check this problem is to take a known working cable from another device and connect it to your gadget. If the problem persists, then proceed to the next step.

4. Test the power adapter

The charger is also often a source of problems. We are talking about that very small box that is plugged into an outlet. First of all, touch it to check the temperature. An adapter that is too hot, like one that is too cold, can serve as an indirect sign of failure. Make sure the cable connection is in good condition and clean it if necessary. Try to find another power adapter that suits your specifications.

5. Buy a new battery

Modern technologies have made batteries much more durable than before, but still not eternal. Each battery has its own lifespan, expressed in the maximum number of charge and discharge cycles. If you use your gadget intensively and it is already several years old, then it is likely that the battery life is running out. To check this, simply take it out and make sure there are no bulges, smudges or other signs of aging. However, it is most reliable to check the voltage supplied by the battery using. If it is too low, then you should look for a replacement at a service center or online stores.

6. Do a factory reset

If you have gone through all the steps and none of them helped you figure out the cause of the problem, then perhaps the problem is software glitch. operating room Android system collects device usage statistics in order to prevent the battery from being completely discharged. In some devices, a full discharge causes the built-in power controller to malfunction, which in turn prevents the device from accepting a charge as usual. In this case, resetting the device to factory settings may help (remember to do this first backups important data). Of course, this is an extreme measure and you should only resort to it if you have already tried everything else.

In this article, I tried to describe the most common problems with charging gadgets and ways to solve them. Of course, in real life there can be much more. Write about the cases you have encountered in the comments.

Phone or tablet not charging? We have some tips and tricks in store for this case.

During the entire stay with its owner, a smartphone can be thrown away different numbers, but one of the most common problems is that it suddenly refuses to charge. And there are many reasons for this behavior, some of which we highlight in this article. And also tips that are worth trying before going to a service center and paying money for repairs.

Problems with accessories that prevent your phone from charging

When identifying a problem, the first step is to check the most probable reasons a problem occurs. A few tips below are quite simple, can be done quickly and without any auxiliary tools.

Inspect the charger cable

The charger cable is usually the cheapest and most fragile part. It can become unusable if it is twisted or bent too much. Therefore, it is worth trying to use a different cable that is definitely not damaged.

For example, borrow from a friend or work colleague if you don’t have a spare at home.

And then you just need to connect this cable to the charger, then to the phone and see if it is charging or not. If not, then the problem is not with the cable, but with something else.

Check the power supply

Likewise, it would be a good idea to check the charger. Again, to check we use another, one hundred percent working power supply and look at the result.

If you discover that the problem is with the cable or charger, you can always purchase inexpensive new options, including online.

Perhaps the case is too big

For those who have recently purchased protective case for your smartphone, you need to make sure that the cable fits tightly into the connector.

Sometimes a large case will cause the charging cable to become dislodged so much that the connection breaks and charging stops. It very rarely happens that the problem is in the case, but it doesn’t hurt to check this option.

Common problems in Android that interfere with charging

So, we checked: it’s not the cable, the charger or the case. Then let's check the device itself.

If your smartphone won't charge after being left idle for a long time with an empty battery, it may need a little shake-up. You should try quickly inserting and unplugging the charger plug from the socket several times. Sometimes it helps.

You can also look at the manufacturer’s website or support forum, perhaps there you can find some working option or combination of actions that solves this problem.

Clean the contacts in the connector

Over time, the connector on the phone becomes clogged with small debris, dust and dirt. A high concentration of such unwanted guests can lead to charging problems. To clean the contacts, just blow thoroughly inside the connector.

If dirt doesn’t want to leave the cozy nest of your smartphone just like that, you can clean the connector with a vacuum cleaner or a straightened paper clip, the main thing is to do it very carefully in both cases. To clean the vacuum cleaner safely, turn off the device and use a plastic funnel to avoid accidentally scratching your phone.

You can also use a folded piece of paper with a sharp edge that you can stick into the slot to help tidy it up.

Update software

Not often, but sometimes due to an update operating system There are charging problems or errors in battery power management.

If the OS on the smartphone is very recent, and around the same time a problem with charging appeared, perhaps these events are related.

In this case, you may need to rollback to previous version operating system, the problem is that this is not possible on every device.

But instead, it is better to check if another update has been released for the smartphone. New software usually fixes problems that existed in the past.

1. To update the system on Android, open “Settings”, go to the “Software Update” section and select “Update”.
2. iPhone users have a slightly different path: “Settings” → “General” → “Software Update”.

Change battery

This is not possible on most modern phones because the battery is built into the body. But if your phone or tablet has a replaceable battery, then you should replace it with a new one.

Over time, batteries naturally degrade and cannot store as much electricity as they once could. This usually happens over a long period of time, but in some cases it can happen out of the blue. In order not to waste money on buying a new one, it would be wiser to take a suitable working battery from friends or acquaintances.

You can also go to the store, explain the situation and ask for the battery to be checked.

It's time to buy new phone?

For those who don’t want to bother at all with finding the cause of the problem, there are only two options left. Either take the gadget to a service center (if the warranty is still valid, we take it to the seller from whom we bought it), or replace the smartphone with a new one.

Obviously, the last option is the most expensive, but if the device has already worked for a decent period of time and has recently started to fail, then why not replace your old one with a younger device?
