Top 10 Reasons Why your Smartphone Won’t Charge? (2021 Best Guide)

I came in the evening after work, put the phone on charge, and in the morning the battery is dead.”

“The phone seems to be charging, the indicator shows that the charge is on, and as soon as you disconnect it from the network, there is no charge at all.”

“The phone was charged for a day, and after a few hours of use it was almost completely discharged.”

The service center staff encounters a list of such problems every day. What actually happens to the device and its battery?

In this article we will talk about real problems with batteries in smartphones, and give a couple of tips on how to troubleshoot phone charging problems.

The main reasons for the incorrect operation of the smartphone battery:

  • Charger does not work
  • Incorrectly matched charger
  • USB charging cable does not work
  • Broken USB connector
  • Battery defective
  • Virus in the system
  • Services running in the background
  • Broken power controller
  • Temperature conditions for using the device
  • Deep discharge of the battery

Charger does not work

Yes, it is a broken charger that often becomes the reason why your smartphone does not charge normally. To check if the reason is actually charging, take a charger from another smartphone and try charging with it. If the charge has gone, it means you need to replace the charger. It is almost impossible to fix the charger, and there is no need to. Today, there is a huge selection of chargers on the market: from budget options to expensive original accessories from smartphone manufacturers.

Incorrectly matched charger

It would seem that all chargers are the same. But no. Modern smartphones require more powerful power supplies. The charger that you fed your smartphone 3-4 years ago will not work for a modern flagship. The phone will charge, but for a rather long time, and then it will also be quickly discharged. After that, you may suspect that the device has begun to malfunction. 

USB charging cable does not work

This is another rather commonplace and popular problem regarding phone charging. USB cables tend to wear out. Outwardly, such cables may look brand new and intact, but the phone will take much longer to charge than usual. The reason is that all cables tend to stretch, as a result of which resistance increases and the phone takes much longer to charge. Also, over time, the cable connector looses, the contact deteriorates, and again, charging the device takes longer than usual.

Broken USB connector

This is a fairly common reason why your phone may not charge. It is very easy to check if the USB port is really broken. First, check if the outlet from which you are going to charge your smartphone is working. Take another charger and connect it to your smartphone. If the phone does not charge after replacing the charger, the problem is most likely in the USB connector.

What to do if the USB connector on the phone does not work?

First you need to clean it. Often people carry the phone in their pocket or bag, where dust, small debris that gets into the USB port and clogs it. Also, the system connector can oxidize over time under the influence of moisture, for example, after visiting the pool, sauna, talking in the rain, outdoor recreation, etc.

Before you start cleaning the port, please note that all the parts in smartphones are rather fragile, so force cannot be applied to them. At the start of any repair work, you must turn off the phone and remove the battery from it, if possible. Do not use sharp metal objects! A regular toothpick is fine for cleaning the port. Use it to gently clean the port. Then, take a regular dry toothbrush and cut it off, leaving a narrow strip of bristle. Dampen the brush with alcohol or a special contact cleaner and clean the contacts again.

After cleaning the contacts, insert the battery and try charging your phone again using different chargers.

If the cleaning of the port does not give results, you need to contact the service center.

It is strictly forbidden to:

  • Use a needle to clean the phone while it is on. This will burn all contacts.
  • Loose the nest. If you loosen it, then without the help of a specialist, the phone can no longer be repaired.
  • Pour alcohol or other substances into the port.
  • Clean the nest with a cotton swab.

Bad battery

As soon as you notice a problem with your smartphone charging, take a look at its battery. If it is swollen or has changed shape, it urgently needs to be replaced. You can select and buy a battery right now on our website in the Batteries section . If you have any difficulties with the choice, please contact our contact center, and we will help you solve them.

A battery malfunction can also be signaled by the fact that the phone is not gaining a full charge. You put the phone on charge overnight, and in the morning the charge level is at most 90% and 20-30% remains until lunchtime. The way out here is the same as in the previous case: the battery will simply have to be replaced.

Often, smartphone owners charge the device incorrectly, as a result of which the battery depletes its resource prematurely. Yes, every battery has a limit on the number of discharge-charge cycles. If you have often brought your smartphone to a full discharge, then your battery has simply quickly exhausted its resource and now needs to be replaced.

Virus in the system

We put the phone to charge at night, in the morning the charge indicator shows 100%, and after 2-3 hours it remains 30%, and at the same time you have not used any complex and energy-consuming applications? There is a high probability that a virus got into your phone while downloading the next application.

What to do if a virus appears on the phone?

To get started, use the usual free antivirus program. It will scan your device and point to an infected file or suspicious application that must be removed immediately. Watch your phone for a couple of days: if the battery is stable, congratulations! You are lucky and lucky!

Quite often, antivirus cannot detect harmful software that is registered in system files. Someone may advise you to reset the settings to factory defaults, do a recovery, and it may even work. But often complex viruses severely damage system files and require specialist intervention. That is why, in such cases, it is better to immediately contact the service center.

Services running in the background

Services running in the background (they are also often called services, daemons, processes) are an invisible part of applications that mercilessly devours your battery and takes up RAM. The work of these services is invisible: it seems to you that you have closed the program, but in fact it continues to work unnoticed for you and collect information from your device.

How can I check and disable programs running in the background?

First, you need to determine which applications are running in the background. Open your smartphone’s battery usage statistics and see which apps are at the top of the list – these are the services that use up the most power.

What to do with these gluttons? It’s simple – delete. If you cannot refuse some programs, look for their economical counterparts. For example, social networks (they are often among the top battery eaters) can be used directly in the browser. This way you save power and memory.

Broken power controller

The battery itself is not always the fault of the rapid discharge of the battery. Quite often, the reason for the malfunctioning of the battery lies in a malfunctioning power controller. This microcircuit is responsible for charging the device, distributing and consuming power. There are several reasons why this part can fail, for example:

  • Fall or hit
  • Voltage drops in the network (controller burns out)
  • Corrosion after moisture ingress

The power controller is a non-repairable part: it can only be replaced. To do this, we recommend contacting specialized service centers.

Temperature conditions of use

After being in too high or low temperatures for a long time, there is a high probability that the battery will start to malfunction or fail altogether. When the smartphone freezes, it turns off because it thinks the battery has run out. In such a situation, it is enough to place the phone in a warm room or put it in an inner pocket, closer to the body. Never place your smartphone on a battery or near a stove.

Also, you cannot charge the phone in a room with subzero temperatures (cars, storage rooms, etc.). Under such conditions, due to temperature fluctuations, the battery may explode while charging.

All smartphone manufacturers indicate the temperature range for specific device models. If you adhere to the recommendations of the manufacturers, then your gadget will not even feel the temperature changes.

Deep discharge of the battery

A deep discharge of the battery (also called a sleeping battery or a sleeping battery) is the lowest possible level of battery charge, after which the controller built into it blocks the electrical circuit inside the battery. 

A deep discharge of the battery occurs when you are actively using the phone, and at some point it becomes necessary not to use it in the near future. For example, you are going to another country where you will not use the device for a month or longer.

 If you discharge the battery to zero and put the phone on the shelf, then after a few weeks you will not turn on this gadget – a deep discharge will occur. The battery has the ability to self-discharge, that is, after you have already discharged the phone, the battery continues to discharge to a critically low level for some time.

What happens to the battery after a deep discharge?

First, you won’t turn on your phone the first time. Long-term charging can help to restore battery operation. Leave your smartphone on charge for 24-36 hours. This method will work if the phone has not been used for a relatively short period of time.

Secondly, if you managed to wake up a sleeping battery, chances are that it will degrade over time and eventually stop holding a charge.

Thirdly, after a deep discharge, the battery becomes dangerous and may even self-ignite.

How to protect the battery from deep discharge?

Leaving the phone for a long time, you need to do the following:

  • charge the device up to 60%. Yes, it is important! Not up to 100%, as everyone used to think, but up to 60%!
  • disable all apps and internet
  • remove the SIM card

The above tips will help to reduce the use of battery power, as a result, it will self-discharge very slowly and will not completely fall asleep even after several months.

Let’s summarize!

Quite often, smartphone charging problems do not concern the battery. This can be caused by chargers, cables, connectors, etc. A 99% battery failure occurs not because the manufacturers made a bad battery, but from improper use of the gadget in general.
