All Android smartphones have something in common - they run out of battery quickly.
This is due to a large number of factors, including the original battery capacity and user settings. Many users are forced to charge gadgets daily, and in some cases several times a day.
In this case, charging speed plays a big role. Users notice that immediately after purchase the phone charged much faster than it does now. There can be many reasons for this situation - let's figure out why the smartphone charges slowly.
Which mobile phones are at risk?
Android, iOS, Windows - a phone with any of these operating systems may be at risk of relatively slow charging. Even a very expensive smartphone can sooner or later die, especially if you use it very actively.
But still, usually phones with large batteries are most susceptible to this problem. For example, Lenovo, LG, Honor, Xiaomi, Huawei, Meizu, Asus. But iPhone, Samsung, Nokia, Sony Xperia and HTC are not so prone to such a malfunction. True, this does not mean that the problem of slow charging will not affect them at all.
The charger or phone does not have a fast charging function
Support for Fast Charge technology is carefully indicated to manufacturers in the specifications included with smartphones and tablets. If fast charging is in place and an adapter of suitable power is already at hand, then the battery on average will begin to charge 50 or 60% faster than when using standard accessories without Fast Charge.
Before purchasing a high-power adapter (especially from the Apple website for iPhone, iPad or iPod Touch), you should check everything in advance. In real life, Apple Fast Charge only works starting with the iPhone 8 and iPhone X, as well as the iPad Pro. Other manufacturers - Xiaomi, Samsung, Huawei - immediately supplement the package with adapters. You won't have to buy anything extra.
How long should a phone charge?
How quickly the phone will be powered depends on the size of its battery and, naturally, on the power of the charging itself.
A new phone with a “native” charger will be charged 100% in 2-4 hours. This time is approximate, since each manufacturer has different battery sizes and memory power.
When the phone is completely saturated, it will notify you about this through a certain signal. In addition, a corresponding message will appear on the screen.
Some modern models have a fast charge function. Thanks to it, you can charge your phone 2-3 times faster.
True, it is better not to use such a function unless absolutely necessary, because this may have a bad effect on the properties of the battery.
IT IS IMPORTANT! When charging your phone, put it aside for the time being. Li-ion and Li-pol batteries are afraid of overheating, and they definitely do not need additional load on the processor. Because of this, there is also no need to charge your phone on fabric surfaces.
Battery is damaged
A worn-out battery in rare cases will increase the time required to fully charge a smartphone or tablet. As practice suggests, everything happens exactly the opposite. With a low battery capacity, energy accumulation occurs many times faster, and at the same time, the charge is lost just as quickly during subsequent use.
A trip to a service center will help you avoid similar problems, where specialists will happily change components for a certain cost (both official and unofficial ones).
Problems with the charger
First you need to figure out if everything is okay with the charger itself.
It can fail for various reasons: a fall, a blow, a pinched or broken wire. If at least one wire goes into the charger, this will certainly affect the battery power supply speed, that is, the charge will begin to flow more slowly.
In addition, the problem may be in the contacts of the device - sometimes they become oxidized or dirty. Another reason for slow charging is a “non-native” adapter.
Try connecting the phone to power through a different charger. If the charging process went faster, then this was the cause of the problem.
Contacts that are oxidized or dirty can be cleaned yourself or contact a specialist. If this does not help, you will need to buy a new charger.
Unstable firmware version
The battery charging speed depends on many factors - weak power supply, faulty cable, damaged interfaces: the list of reasons is extensive and varied, and is often not related to mobile equipment or accessories, but is centered around software. Enthusiast testers have long established a connection between the outdated version of the operating system (we are talking mainly about Android, but in the realities of iOS, do not forget to check the innovations in the “Settings”, section “General”) and energy consumption. As a result, you should take care of downloading timely updates in advance, and after that, the battery charging process will stabilize and return to the standard value.
Problems connecting the charger
It happens that you cannot connect the charger properly. The reason for this may be a broken or dirty hole in the mobile phone. You can try to blow out this nest or carefully clean it.
If you see that the contacts on the battery are oxidized or dirty, you can clean them with a toothpick. When doing this, be careful not to press too hard, otherwise you may permanently damage the product.
There are also problems with the cable - it is bent or broken in some place.
Well, or you are using a “non-native” cable and it has a smaller cross-section (the current voltage is directly proportional to the diameter of the wire). So for charging, it’s best to use the one that suits your phone specifically.
Heavy load
100% brightness, stable gaming sessions and long conversations on the phone or through instant messengers. The operating time of mobile equipment without access to the network is greatly reduced if you run resource-intensive applications every now and then and have fun without interruption.
Weak power supply. The habit of using a computer to charge smartphones and tablets should be abandoned a long time ago.
According to tests, when using the USB0 interface, the charging speed is reduced by three. When using USB 3.0 - double. Therefore, it is better to immediately turn for help to the original accessories - the cable and adapter from the box.
Poor power supply from the cigarette lighter
Using the charging cable and USB output, you can connect your phone to a computer or car cigarette lighter.
True, in such cases the mobile phone can be powered for quite a long time. And there are times when, when simultaneously charging and connecting via an AUX cable to the car radio, the phone is powered slower than it is discharged.
But there is nothing strange about this, and is explained by the fact that less current comes from the computer or cigarette lighter than from the outlet. So it is better to use the cigarette lighter only when absolutely necessary. And for proper nutrition, connect to an outlet.
Charging from PowerBank or laptop
The tests carried out show that laptop USB interfaces (including USB 3.0) are not capable of delivering maximum power when transmitting energy. To speed up charging, it is recommended to use original accessories - cable and adapter.
The situation with PowerBank is different - some manufacturers are already using Fast Charge technology in external batteries (moreover, it has long been easy to find PowerBanks with wireless charging online), thanks to which smartphones and tablets are clearly unable to charge slowly. But here there is a question of price - you definitely shouldn’t count on a low cost.
Battery problems
Sooner or later, any battery will stop working.
And the longer you use it, the worse it will hold its charge over time (and, accordingly, the longer it will last). The battery life is about five hundred operating cycles (discharging and charging). As a rule, this is enough for 2-3 years.
First of all, you need to check the battery capacity to understand the remaining resource. If it has dropped significantly, the easiest way is to replace the battery.
But remember: you should only purchase a replacement battery in specialized stores or retail outlets, otherwise you may end up with a low-quality product.
Cause
If you are trying to charge your phone from a computer device or using the standard method through an outlet and your Samsung phone does not work, then the reason for this may be a faulty cable. First of all, you need to carefully look at all the cords on your phone. If you checked and they turned out to be intact and working, then the reason is not in them. It is necessary to further search for the cause.
The reason may be:
- It is quite likely that the connector itself is not fixed in the phone. If this is indeed the case, then it will need to be replaced;
- If the same connector is slightly torn out of the so-called printed circuit board, the phone will also not charge;
- The power controller may be broken. If this is indeed the case, then it is necessary to replace it;
- If the phone takes a long time to charge, this indicates damage to the power circuit. This part is quite significant in the entire system, so it is necessary to carry out diagnostics before directly repairing it;
- A fairly small percentage may account for other problems.
It is also quite likely that the problem is that the phone discharges quickly, but very slowly or does not charge at all . Then the problem is in the battery itself.
Such problems are quite common and people do not know what to do in these cases. Therefore, we provide solutions to problems.
Failed software update
Another reason for slow charging is poor-quality firmware.
If you recently updated the software on your phone, then it is likely that this is causing the problem. There are several options. Either wait for new updates, or return the software to a previous version. You can reset everything to factory settings.
How long does it take to charge the battery?
It is impossible to give an exact battery charging time for each smartphone or tablet due to the lack of input data related to battery capacity and the availability of fast charging technology. The speed and final result are also influenced by the method of replenishing energy (the long-proven method of recharging with the active “Airplane” mode saves up to 10% of time) and the actual wear of components. If you add the above factors together, it will become easier to tell the time. Otherwise, you should rely on the specifications from the manufacturer or tests conducted by independent experts (videos on the topic are easy to find on YouTube).
Powers up slowly and drains quickly
When charging slowly and draining quickly, there can be two reasons: battery and applications.
That is, in the first case, it is an old battery. And in the second - energy-consuming applications that constantly run in the background.
So either change the battery or turn off applications and programs that you do not use.
If you still have any questions after reading the article, be sure to ask them in the comments. You can also share your experience with other phone owners - what did you do when your smartphone was charging slowly?
What could be the reason for slow phone charging?
Software update
If your phone starts to charge slowly, try to remember: did it receive a software update recently? Most often, such situations arise with Android-based smartphones, which regularly receive security updates and packages to improve the performance of the mobile device. Such updates may well affect battery performance due to an oversight by the developer or due to an error that occurred during the installation process.
What to do: try rolling back the update and see if the charging speed is back to normal? You can also try reinstalling the update and, again, test the charging speed. In the worst case, the smartphone will have to be reset to factory settings. However, if the charging speed is affected by hardware wear of the battery, such “dancing with a tambourine” will not help you.
2. Poor quality accessories (charging cables and docking stations)
The most common culprit for slow phone charging is usually the charging cable, which may have poor conductivity. If you have been using the cable for quite some time and it looks worn out, a contact may come loose (this happens due to frequent kinks in the wire), and this not only affects the deterioration of charging, but can also lead to damage to the phone itself.
What to do: Try replacing the power cord, but make sure that the new cord supports fast charging (if your phone supports this type of charging). We recommend purchasing original charging cables that are certified according to European standards. But you shouldn’t rely on the inexpensive price tags of Chinese analogues. Take care of your phone.
Use cases
If you are one of those users who likes to surf a mobile browser while the smartphone is charging, be aware that this interaction scenario increases the load on the battery and power connector. As a result, the phone battery wears out faster and begins to degrade. The consequence is a decrease in charging speed, which can lead to an expensive battery replacement and failure of the smartphone (keep in mind that repairing modern phones can cost you a pretty penny, so it’s better not to let this happen).
What to do: Give your smartphone a rest while it is charging. Better yet, activate “airplane mode” so that the smartphone does not perform background operations while it replenishes the battery capacity. And, by the way, when the phone is not used, the charging speed increases noticeably.
4. Low power supply and faulty power bank
If you charge your mobile device from a computer and a power bank, you can’t count on fast charging, so it’s best to connect your smartphone directly to a power outlet using the included power adapter. Please note that the power adapter must be branded and not custom. Otherwise, a lack of power may occur at the level of the power supply connected to the mains. As a result, your phone that supports fast charging will take twice as long to charge.
What to do: try to charge your smartphone from the mains and use the supplied power supply or chargers certified by the manufacturer for your smartphone. In this case, the charging speed will not drop and the smartphone will quickly replenish energy.
Faulty charging port
Make sure that the charging cable connector is securely seated in the corresponding connector on the smartphone. If the connector is loose and does not hold the cable properly, this can cause slow and unstable charging. Please note that the USB-C connector input has a two-way contact, which can break due to physical impact and cause current leakage, while remaining functional.
What to do: if damage is detected visually, the smartphone will have to be repaired or replaced with a new device. You can, of course, try to repair the input port for the charging cable yourself, but to do this you need to have the appropriate experience and a set of tools.
Damaged battery
A typical symptom that manifests itself in the process of battery degradation: the battery swells, and the smartphone either develops a noticeable “hump”, or the back cover simply begins to come off, or the screen itself comes off. But battery degradation is not always detected so easily.
Pay attention to the heating: if the phone heats up so much while charging that it begins to noticeably burn your fingertips, this is a reason to think about it. Excessive heating of the battery is also a sign of its degradation. If you charge to 100%, and it discharges by half in a short period of time, the conclusion will again be simple: the battery is finished, and it no longer holds a charge.
What to do: replacing a battery can cost a pretty penny, given that modern smartphones are practically irreparable. If you realize that your battery is on its last legs (slow to charge, overheats and quickly loses charge), it is better to think about buying a new phone.
Background applications
Some applications can heavily load your smartphone even in the background. The more actively they consume battery power, the slower the device charges. More precisely, no, it charges as expected, but at the same time it loses charge. So it feels like the energy replenishment time has increased.
Typically, smartphones themselves notify the user that there is an application in the system, the background processes of which heavily load the battery. However, it would be a good idea to independently view the battery load statistics in order to exclude the presence of “energy-hogging applications” on your smartphone.
What to do: We recommend deleting apps that are haphazardly draining your battery, even when your phone is charging and not in use.
And don’t forget to turn on “airplane mode”.
Motherboard
Carries out the main work of the laptop; it contains the processor, RAM, video card, other chips and connectors.
Breakdowns occur when the motherboard overheats, when liquid gets in, after a shock or fall, during power surges, over time (after 5-7 years).
Symptoms of a board failure:
- The laptop does not turn on and does not respond to the power button;
- no image appears when turning on the laptop;
- constantly reboots;
- the system does not boot;
- an error appears when initializing drivers;
Keyboard
The input device consists of groups of conductive tracks; when you press a button, they close, which is processed by a multicontroller located on the motherboard.
Keyboard failure usually occurs after it is flooded with liquid - in this case, the buttons usually fail 5-6 at a time. In this case, you need to replace the laptop keyboard with a new one. In rarer cases, the keyboard mechanism breaks down or gets clogged (the buttons are harder to press), in which case the keyboard can be repaired.
Troubleshooting
First of all, it should be noted that if the problem is not with the charger, then it is best to contact a specific service center. They will quickly carry out the necessary diagnostics and determine the cause that you were unable to determine.
In many centers, all parts are available in order to replace the breakdown and provide repairs of the highest quality. Often, in all centers the price for phone repair is acceptable. Moreover, the advantage of service centers is that they provide a guarantee for the entire phone.
A fairly common reason for a phone not charging is a breakdown of certain electronic components in the phone. In the event of such a breakdown, any service center must explain to the person the reasons for this malfunction and what to do to prevent this from happening again. It is also worth understanding that when they say that the phone is not charging, they also mean that the phone’s battery is quickly draining.
A fairly common and common reason is the battery breaking down due to long-term use. In such cases, you can simply replace the battery with a new one, and it will last for a long period .
Very often the phone turns off due to low battery when a sound or vibration signal is sent. This is justified by the fact that the phone once fell and such a breakdown occurred.
Not so often, but the phone is discharged due to internal problems, namely, some kind of virus. This reason only happens on smartphones. To prevent such a problem, you must remember that antivirus can be used not only on computers, but also on mobile devices.
