80% of smartphone users are faced with the fact that their battery has suddenly stopped charging. There can be many different reasons for this. In some cases it can be repaired at home, but sometimes the only way out is to purchase a new battery. Let’s take a look at the following steps of what to do when your battery has stopped charging.
This step-by-step instruction is universal and suitable for all models and brands (Android, iOs, Windows): iPhone, Alcatel, Asus, Lenovo, Meizu, Philips, Nokia, Oppo, Phillips, Prestigio, Sony Xperia, HTC, Samsung, Xiaomi (Redme), ZTE, BQ, Vertex, Micromax, Umidigi, Oukitel, Texet, Leagoo, Dexp, Doogie, Huawei (Honor), HomTom, etc. It does not matter whether the battery is built-in or removable.
Try these tricks if the phone has suddenly stopped charging.
Try another cable
Main indicators that the cable is broken:
- The charging process is taking too long (ie: after 2-3 hours the battery is not even 30- 40% charged),
- The phone does not react to adapter connection,
- The percentage of charge declines during charging,
- Android or iOS displays an error like: «This accessory may not be supported or damaged».
There is no need to immediately purchase a new charger. First of all, make sure that there are no problems with the cable. There are 3 different options for smartphone connectors:
- Type-C (Expensive models),
- Lightning (for iOS and iPad).
It’s not difficult to find another cable. Just borrow the cable from one of your relatives or friends. This tactic usually solves the problem in 65% of cases. If the phone starts to charge, then the problem was the cable.
Test your outlet or power source
A malfunction of the charger («wall-mounted» power adapter with USB output) occurs in 10% of cases and is the reason for a lack of recharging. To test the adapter, we recommend connecting the cable and any other mobile phone to the USB connector. It is recommended to check Android smartphones via iPhone charger and vice versa.
Inspect the Connector (charging port)
- It is necessary to clean the charging port of debris, dust or sand grains.
- Check if the connector lacks an end float or if the connector falls out. This action will not take place if the contacts are displaced by a fraction of a millimeter.
It is also important to ensure that the device is not in an excessively humid environment (ie: it did not fall in water, snow, a toilet bowl or a sink), because contact pads can become oxidized. In 8% of cases the smartphone charge is restored after cleaning.
If this does not help, carefully inspect the connector for mechanical damage. Usually the bends of the contacts are visible to the naked eye. If there is mechanical damage, then it is recommended to turn to professional service, because it is almost impossible to repair such electronics at home.
WARNING! We recommend purchasing covers that will protect the charging connector.
Change the battery
The main indicators of a dead battery:
- It charges quickly (within 30-40 minutes), and the battery percentage is literally accumulated before your eyes; it quickly discharges within 15-60 minutes thereafter.
- The charging process only takes place when the phone is turned off.
- The phone gets hot (up to about 40-50 degrees Celsius). Heating to 30-35 degrees is normal.
- The charging process cannot be completed up to 100% – even when using a powerful adapter.
If none of the recommendations above have brought the desired result and the phone still does not charge, then we recommend replacing the battery.
Common cases when the battery becomes unserviceable:
- «The time has come» – the exceeding the number of recharging cycles, usual Li-ion battery can charge about 300-400 cycles.
- Due to overheating or being in cold places too often (when the smartphone shuts down itself).
- In the event of a partial charge up to 100% and a discharge to 0. It is recommended to maintain a battery charge between 20% to 80%. This will significantly extend the life of your device.
- Sometimes the battery swells and deforms the case. This calls for a definite replacement! Do not follow the advice of unauthorized experts who recommend calcining the power components. Such actions may result in a fire or explosion.
Use antivirus software
Android, iOS is buggy or the system has caught a virus. This program will protect your phone from viruses and will warn you about dangerous sites and programs.
This advice helps only 2% of cases and only if the operating system is buggy. In this situation the device not only keeps a slow charge, but also functions slowly and buggy.
Also, it is worth paying attention to the additional load taking place on your phone via:
- Watching video (including YouTube),
- Enabled hotspot via Wi-Fi to other devices,
- Viruses (causes increase of traffic consumption from the tariff package),
- Weak power source: charging adapters with 0.3- 0.5 A are not suitable for modern smartphones. This problem is more typical among portable chargers and external power banks. The current in the power bank does not exceed 1 ampere, while some batteries require a current of at least 1.5- 2 A.
- Check the charger and electric cord.
- Inspect the connector. Perhaps it is clogged with dirt, dust, or rust due to which energy does not flow to the controller and therefore to the battery.
- Perhaps the battery has died.
If the battery is more than 5 years old, then this is probably the issue. Replacing the battery may be the only way to solve the issue.
- In rare cases, the problem is in the adapter or cable. Broken cords are the reason for the lack of energy to start charging.
- Check if the battery has swollen or smudged. You can try to restore the capacity. To do this, you need to completely discharge the phone, then connect the charger and hold it for several hours longer than usual. Repeat for 2-3 cycles. You should buy a new battery if the situation has not changed.
- The battery is damaged due to a short circuit.
- If the system indicates that moisture or condensation is detected: turn off the device immediately and dry it for a couple of days.
- The motherboard or power controller is full of water: in this case, we recommend turning to professional service as self-repair can aggravate the situation.
Sometimes the problem may be that the wireless station did not recognize the smartphone. The indicator will flash but the process will not start. To fix this problem, remove the phone from the station, wait 5-10 seconds, then try to charge it again.
You should disconnect the data transfer via USB cable- from either a computer or laptop - before you put your phone on a charge.
WARNING! Make sure that the device lies exactly in the center of the station. Displacements are permissible within 1 centimeter.
- Usually the problem is that the transmitted current with a magnetic cable is less than 0.8 A. The best option for operation is 2 A, and even better 3 A.
- The magnetic tip frequently gets filled with dirt; so, clean it regularly.
WARNING! This option is not suitable for devices with a non-removable battery.
To use this method follow the next steps:
- Remove the battery.
- Insert the battery into the «pulling sock» so that the terminals are connected to the ‘+’ and ‘-' contacts.
- After that, plug the device into a power outlet. If a green light appears, it is connected correctly.
- It takes about 2-3 hours to fill the battery.
WARNING! If the battery broke down, the described measure will only be a temporary fix. So, in the future you will still need to change the battery.
Sometimes the smartphone software fails. Restart your phone to fix the problem. If this does not help, make sure that there is enough current to charge from the USB port of the PC. Try inserting the cable into another laptop or computer. If this does not help, then the problem is in the phone itself.
- In the car cigarette lighter itself, precisely in the absence of electricity (fuses burned out, the contacts were deformed),
- The adapter from 12 to 5 volts does not work,
- Not enough current,
- It is worth checking the cable for proper operation.
High temperature in this case can be explained by a malfunction of the battery or its overload; for example, downloading programs during recharging or playing resource intensive games. If you don’t use the phone and the battery is still very hot (above 40 degrees Celsius), it has most likely broken down.
If the device reports a low battery temperature, then the smartphone is probably in a really cold room. If the air temperature is normal and does not fall below 0, the battery should be replaced.
In order to make the smartphone work correctly, including charging normally and keeping the charge, we recommend you to stick to the following tips:
Do not drop it
Drops, especially on a hard surface, can lead to damage of phone parts- including the battery.
Do not charge too often
- Avoid using the smartphone 24 hours a day.
- The battery must not be fully discharged.
- Keep the battery level between 20-80%.
- Do not leave the phone connected to a charger all night.
Maintain temperature conditions
Most electronics are not recommended to be left in extreme cold or extreme heat. Suitable working temperature is between 3- 45 degrees above 0.
Do not use low-power charging devices
Chargers with a capacity of less than 0.5 A are not suitable for smartphones. The optimal level is 1-2 A.
Now you know what to do if the phone does not charge or does not recognize the adapter. But, it’s better to repeat everything again:
With proper use of the smartphone the battery will last up to 5 years (300-400 full cycles). This is the normal battery life. When buying smartphones, it is better to give preference to those with the opportunity to replace the battery by yourself (without professional service).
