Problems with chargers and batteries in mobile technology occur quite often. As a result, phones stop charging or hold a charge. One of the most common problems is that the phone takes a long time to charge. This occurs after prolonged use of the device or as a result of some kind of breakdown. Let's try to figure out why this is happening and what to do about it.
Is your phone charging slowly? It is possible that you are using the wrong Charger... This often happens when changing the handset, when the owner continues to use the old memory (it is quite natural, given that almost all phones now have the same connectors). Due to the different charging current, the charging speed may be slow. Therefore, for successful replenishment of the battery capacity, it is necessary to use only complete chargers.
If the complete charger is out of order, you should buy a new "charger" with a suitable current strength in the nearest communication store - compare the parameters on the original charger and on the purchased one.
If the phone takes a long time to charge, then the problem may lie in a decrease in the charging current provided by the charger... Such a breakdown is diagnosed using a multimeter. We disassemble the charger, switch the multimeter to ammeter mode, turn it on in the open circuit and look at the current strength.
How to find out the initial indicator of this parameter? It can only be estimated roughly - if a 2000 mAh battery was charged in 2 hours, then the current in the circuit was just over 1000 mA (taking into account losses).
If the phone takes too long to charge, and the multimeter shows a current of 200 mA, then the charging process will take over 10 hours. There is only one conclusion - you need to buy a new charger, having previously used a known good charger.
2. We deal with the battery
Does your phone take a long time to charge and discharge quickly? All of this indicates that accumulator battery in your gadget has exhausted its resource - you need to change it. By replacing the original battery, you will be able to use the device as before. If you choose a non-original battery, the time autonomous work gadget may decrease slightly- this is quite natural.
Some might argue that the fast discharge may be due to the gluttonous software installed on the phone. This is true, only the charge rate remains practically unchanged.
When addressing this problem to the employees of communication salons, you can hear the following recommendations - the phone must be completely discharged, then charged for 10-15 hours, repeating this cycle 3-4 times. 10-15 years ago, when nickel-metal-hydride batteries were in use, such a scheme could work. This approach will not help modern lithium-ion batteries. But a very deep discharge can do harm.
3. We deal with the software
Is your phone charging slowly? It is possible that you have used programs to save battery and manage charge. A typical example of this is the Battery Care application - it provides for some interesting multi-stage charging scheme, supposedly providing a better filling of the battery with electricity.
If you actually used one of these apps, try uninstalling it, reboot and try charging the phone again. If you checked the charger, replaced the battery and removed all the profile software, but nothing helped your phone, try giving the device to service center- here he will undergo diagnostics using measuring equipment.
Sometimes faulty electronics are the cause of the slowdown.
Why is my Android charging so slowly? Why does the battery drain too quickly? These are very frequently asked questions on the Internet. Good smartphones come with powerful hardware and displays with high resolution which consume a lot of battery resources. In addition, there are a number of other reasons.
Broken cables and adapters
The first culprit for slow charging is often the USB cable. They bend, curl, curl: none of this is great for maintaining a strong connection and flowing power.
If the cable that came with your device is no longer reliable or you just lost it, beware of buying cheap options. Higher quality cables have copper wire (some manufacturers use aluminum and other substitutes that cannot withstand stress) and a thicker rubber sheath around the wire, making them more resistant to damage.
The USB connector itself also wears out. For example, when you connect a cable to an adapter or phone, it dangles, falls out, gets clogged with dust. If this is the problem, then you can try cleaning the dust with a toothpick.
You may have a damaged charger. If your phone won't charge from a wall outlet, try checking the power adapter (a small box that fits into a wall outlet). If it is too hot or, conversely, cold, this may be an indirect sign of breakdown. Connect your phone to your computer via a USB cable. If it starts charging, the problem is with the adapter. Go to any hardware store and buy a new one for the model of your device.
Weak power supply
This is the simplest possible reason slow phone charging. You can easily check if this is the case by simply plugging the USB into a different adapter. If the charge is still not flowing, chances are that the outlet itself is not working. You can try charging your phone from a wall outlet in another room.
Absolutely all modern smartphones have the ability to charge not only from the outlet, but also from other devices, such as a computer or an external battery. power bank via USB port. But alas, if you are using a computer then your phone will charge very slowly. The point is that the output voltage will be too low. And that under ideal circumstances, any damage to the USB cable or ports could disrupt the meager power flow and take even longer to charge.
Likewise, if you are using wireless charging, you will get a rather slow charge. Nobody says that wireless charger not cool, but speed will have to be sacrificed.
Old software
Slow charging is not only a hardware problem, but also possible problem with software. If the software crashes or is out of date, the phone also cannot consume power, and, accordingly, charge.
Also, if your phone has a problem with an old charger after you've updated the gadget to a new one Android version your phone is probably not capable of working with it. Then you should consider downgrading to an earlier version of Android or purchasing a new charger.
Simultaneous use
Even though the screen is the first raging consumer of charge, you may have some apps running in the background and consuming energy all the time. As a result, your phone charges much more slowly.
The simplest solution here is to clean the task manager and check it more often for possible applications running in the background. When you find an app that is consuming a lot of power, try uninstalling it and analyzing battery life and charging speed to see if those numbers will improve over the next few days.
If I had a dollar, every time people complain that the battery in an android smartphone takes a long time to charge, then I wouldn't have much left for a millionaire.
This is of course a joke, but there is such a problem. People in large quantities buy phones that allow you to watch movies, listen to music, play games, and everyone understands that such a device can be charged.
It should only be noted that today we charge our smartphone almost every day, but if you do not treat the battery correctly, then for several months, then you will have to connect your device to the charger every few hours.
In addition, there are a few rules to apply to a battery so that in a year the battery does not become only suitable for trash - especially if you have one of the new, chic types where the battery cannot be replaced without a specialist.
This was an introduction, and now I'll tell you in order: why the phone started charging for a very long time, quickly discharged and what to do then.
How long should an android phone or smartphone charge
You can find out the state of the battery of your android device. ...Phones, like smartphones for example, samsung galaxy, lenovo, xiaomi, meizu, asus, htc, lumiya and te-de., a lot and their charging time is different.
A full charge of a push-button phone or a modern smartphone takes on average 0.5 - 5 hours. So with a capacity of 1500 mAh it will charge faster than with a 3000 mAh one.
Moreover. If the phone is turned off, it will also charge faster than when it is turned on, and you are also watching a movie, which is not recommended. Some smartphones support fast charging, then the charging time increases dramatically, but wears out faster.
Therefore, before you start to panic why the phone battery takes a long time to charge, look at the battery capacity - perhaps this is his norm
The reasons why the phone takes a long time to charge and quickly discharges
What is the reason that the phone takes a long time to charge and quickly discharges? The reason is not one, but the main one, of course, is in the battery itself.
Perhaps you have the Internet, bluetooth, GPS, player working while charging, many applications, cool wallpapers are open, you are listening to music and so on.
All this undoubtedly affects the charging speed of the battery of an Android phone or smartphone.
Also, the reason may be usb socket or controller. The connector can be cleaned, the contacts can be bent.
Another reason is the charger itself. Try another one or from a computer. There are also precedents when the charging speed increased when the cable was replaced (I was convinced personally).
Moreover, you can safely try to change even the original cable, for another - there are examples that the problem is being solved.
Above, I gave just a few reasons why the phone took too long to charge, but here we go.
Summarizing the main reasons for a long phone charge
- Bad contact of USB port and micro USB
- Bad cable
- Bad adapter (charger).
- Bad phone or smartphone battery
- Bad firmware (upgrade)
- Along with charging, many unnecessary processes are running
What to do when the phone started to charge for a long time
If for example you smartphone samsung galaxy s3, s5, j3 and so on, try to determine what the problem is with the GalaxyChargingCurrent program. With its help, you can determine in which direction to move.
NOTE: an old, worn-out battery can charge faster than a new one - a paradox, but a fact.
You can also calibrate the battery. How - Not always, but sometimes calibration solves the problem.
ATTENTION: wireless charging is available in some smartphones today, for example, Lumi 92, or Samsung Galaxy S4, but it is better not to use it - it significantly reduces the life allotted to it.
IMPORTANT: Do not completely drain the battery. A fully discharged battery and unused for a long time should not be suddenly charged to full - this could put it at risk.
REMEMBER: The increased temperature that accompanies the charging of the phone will reduce the life of the battery and other electronic components.
How to prevent your phone from charging too long
Do not allow full discharge. A partial charge is better than a full charge. Do not expose the battery to high or low temperatures for an extended period.
If you actively use the battery, after a while (a certain number of cycles), its performance will significantly decrease.
Then don't be afraid of replacement. Contrary to what people might think, even on devices without a removable back cover, you can replace the battery, except that it may require handing over the phone to a specialist.
The worst thing that can be is when the phone does not have the ability to replace the battery and the end of its life marks the end of the smartphone.
There are, however, ways that you can charge your phone faster and keep it in good condition for longer.
Tips for Avoiding Long Charging of Your Phone or Smartphone
Best of all, do not charge your device at night - he himself cannot "wake up" to trigger an alarm.
At night, use a weaker charger. Batteries last longer when they are less charged. Charge the battery at room temperature - preferably below 25 ° C and above zero.
If possible, do not fully charge your phone. Up to 85-90 percent is quite enough for a longer maintenance of the condition.
If the temperature increases by more than 10 ° C during the process, then something is wrong. Replace charger.
If you are addicted to fast charging, use a short, thick cable. The current losses will be less. Be careful on hot days - do your work in a cool place. Beware of cheap chargers.
The cheap ones do not take into account the characteristics of the battery. I also recommend watching a video on how to increase battery life in your phone. Good luck.
All Android smartphones have one thing in common - they drain quickly.
It's connected with big amount factors including initial battery capacity and custom settings... Many users are forced to charge their gadgets daily, and in some cases, several times a day.
In this case, the charging speed plays an important role. Users notice that the phone charged much faster right after the purchase than it does now. There can be many reasons for this situation - let's figure out why the smartphone is charging slowly.
Defective cable or power supply
The first reason is trivial and occurs quite often - a low-quality charger. This can be verified by simply replacing the power supply and cable. If nothing has changed, chances are high that the problem is with the hardware of the device - battery, USB connector, or power controller.
Power controller problems
To check if the reason for the slow charging is the power controller, you need to charge the turned off smartphone. If the process takes too long, then the problem is most likely a hardware problem. In this case, the device must be taken to a service center.
Outdated software
Did the device charge quickly? The problem is probably software... You need to go to the settings, check for software updates and install them. It does not hurt to clean your smartphone from unnecessary data, applications and other debris.
Uncalibrated battery
Another reason for slow charging is a poorly calibrated battery. It is very simple to understand that the reason lies precisely in this - in such cases, the smartphone often does not charge 100%. You can calibrate the battery manually or using special application- all the details .
The battery is out of order
The battery has its own lifespan. If the phone is more than 2 years old, it needs more time to fully charge. Often, old Android devices with worn-out batteries behave unpredictably - they turn off, drain quickly, and so on. In this case, it is recommended to replace the battery.
Weak source
Some users prefer to charge the gadget using a laptop, computer, or similar energy sources. This is not entirely correct, because such USB connectors provide too little power, therefore, the charging speed drops. The surest source is the outlet. The above methods can be used as an exception.
Charging your smartphone while using it
How often do you connect your phone to a power source and start sitting in social networks, browser and YouTube? This may also be the reason. long charging... In principle, you can use the device, but it is better to turn off resource-intensive programs and lower the brightness - this way the device will charge faster.
If the smartphone is charging too slowly, do not rush to contact the service center - first check it for all the above points. If you cannot correct the situation on your own, you can contact the specialists.
Mobile devices are called that way for a reason. Nowadays, of course, our devices have much more functionality, huge displays that consume a lot of energy, but you can't get away from the roots. Smartphones should always remain as mobile as possible. Take a look at the user polls for which uptime was the most important metric.
However, not only the operating time is determined by the mobility of the gadget, but also by the charging speed. There are currently many fast charging technologies that can charge your device up to 70 percent in just 30 minutes. However, with this, some users may have a number of difficulties. Does the smartphone charge for 3-4 hours? We will try to find and fix the problem.
Before you blame a faulty one or another update to a more recent version of Android, try to first check the cable for external damage. Not much attention is paid to the USB cable when it comes to its long service life, on the contrary, many manufacturers have begun to produce protective sheathing of cables from organic substances, which leads to faster failure, by the way, Lightning is a good example of this.
Check to see if the protective cover has torn on your cable, and it is likely that the cable was in a very cold place. In any case, the first thing to do is test it on a different device. If everything works fine, go to the next step, otherwise replace your USB cable with a new one.
In the meantime, the USB port should also be checked for external damage. In addition, it may corrode if the unit is submerged in water.
Weak source of energy
Try not to charge your smartphone using a computer or laptop, because the transfer of energy in this way is very slow. USB 2.0 transfers up to 2.5W (0.5A / 5B), while USB 3.0 transfers up to 4.5W (0.9A / 5B).
Defective adapter
Evaluate the power adapter for external damage, if no problems were identified, check the adapter parameters: if the current is only 1 A, the device will charge slower than in the case of 1.5-2 A. However, it is worth remembering : not every smartphone supports such indicators. Always try to use the standard adapter included in the kit. Meanwhile, some modern devices support Quick Charge, and usually there is no QC adapter included, it must be purchased separately.
Your smartphone is outdated
If you have been using a gadget for more than two years, do not think that it will charge as quickly as modern devices of 2015 that support various fast charging technologies. Want to keep up with progress? - you should buy yourself a new one modern smartphone.
The battery is out of order
Typically, the battery life is very limited. Already after 1-2 years, the device will begin to charge more slowly, and by the age of three it may even start to turn off, for example, after passing the threshold of 50% of the remaining charge. This only says one thing: the battery should be replaced. Owners of devices with a replaceable battery can replace it themselves, others are advised to contact the service center.
The problem is you
Try not to use the device while charging. If you decide, set the screen brightness slider to a level below average, because most of the energy is spent on the display backlight. Close running applications from the multitasking window, "kill" unnecessary processes, wakelock, for this you can use Greenify or Wakelock Terminator, for example.
