Perhaps you’ve noticed a blue flashing light when you place your phone on the wireless charger? If you’re wondering what that means, this article will provide all the information you need about wireless chargers flashing blue.
Why Wireless Charger Blinking Blue Light?
When your wireless charger flashes blue, it means something is wrong with it, and it’s not charging properly. Using a charger with a continuous blue flashing LED can damage the charger or your phone.
Therefore, you should try to find out what’s causing the problem and fix it. There can be several causes behind blinking blue lights on a wireless charger while charging any phone.
1. Coil misalignment
Wireless charging is a method of powering the phone by using the inductive effect involved in charging between the coils of the charger and the phone. In other words, if there is a misalignment between the phone and the charger, then the charger will not be able to charge the phone properly.
2. Cables/adapters that are faulty
If you have faulty USB cables and power adapters, you might be experiencing a technical issue. If this happens, the charging process can be slowed down.
3. Updating errors
A seamless wireless charging experience depends on software compatibility. The charging process will be obstructed if there is a discrepancy between the phone’s and the charger’s software. Old or incorrect software updates can also cause a flashing blue light on wireless chargers.
A vibrating phone shifts its position while charging. This disrupts and ruins the alignment of the phone with the charger. An interruption in alignment will result in an interruption in charging.
Any magnetic or metallic substance will obstruct the induction effect between the charger and the phone. It will also affect the phone’s ability to charge due to interference.
6. Fast charging is not compatible
It is important to note that not all phones are compatible with the wireless charger’s fast-charging options.
7. Interference by the N.F.C.
Near Field Communication is also known as N.F.C. Wireless technologies such as NFC and Qi are both used in charging systems. However, if both are used simultaneously, the N.F.C on the phone can interfere with the charging system.
8. Features of Daydream
By using Daydream, you can display notifications and screen savers while keeping the phone in use. Unfortunately, this drains the battery charge and overloads the processor. When your phone is heated, you also end up with a flashing blue light on the wireless charger.
9. An overheating condition
The most serious problem with charging is overheating. There have been instances where phones can get so hot while charging wirelessly that the process is interrupted. The phone implements this safety measure to protect itself and the battery from severe damage causing blue light to flash.
10. A faulty charger or a defective phone
It is possible that you may have a defective charger that you are using with your device. For example, a wireless charger is blinking blue light means it’s malfunctioning.
Wireless chargers with blinking blue lights: Top solutions
Using good quality wireless chargers is always the easiest solution. There are other ways to prevent wireless chargers from flashing blue lights.

You should ensure your phone is positioned correctly on the charger. Make sure you check the manual for the correct placement. An adequately aligned wireless charger usually does not flash blue lights.
2. Don’t use ordinary cables or adapters
Use only original or high-quality adapters and cables. Ensure all cables and adapters are authentic and appropriate for the wireless charger. Use the original USB cable for charging purposes and keep it separate from other cables.
3. Make sure the vibrator is off
When charging, turn off the vibration mode to stop the vibration. You need to check your phone’s vibration mode before docking it for charging.
4. Make sure your phone is up-to-date
By opening the settings, ensure that your phone’s software is up to date. Before charging your phone, install the latest update. Make sure you installed the original version from the manufacturers.
5. Charge in standard mode
When it comes to charging, switching to the standard mode is preferable to fast charging. It is common for the phone to be overheated during fast charging, tripping the charger and the phone. It can also cause some incompatibility issues between the charger and the phone.
6. Ensure a dust-free environment
Ensure the plug environment where you charge your phone has minimal dust and cool. The heat from the environment can interrupt the charging process; the charging system may stop working.
7. Switch off the N.F.C
Make sure the NFC feature is turned off before charging. As a result, the Anker wireless charger will no longer flash blue lights while charging. When charging your phone, you should also disable Daydream.
8. Wireless charger reset
It is possible to reset the wireless charger by unplugging and replugging the adapter. If there are any internal issues with the charging device, this will resolve them. Next, you should restart your phone. Then you’ll be able to stop any app or process running in the background, making your phone error-free.
9. Take off the cover
You should remove any protective cover on your phone before charging it. It is common for covers to slow down the charging process. A flashing blue light will indicate that the charging is inadequate.
10. All obstructing coins must be removed
It is also possible for coins or magnetic materials to interfere with the inductive charging process. Remove magnets or coins around the charger to ensure uninterrupted charging.
11. The charger heats up
Take some time off from the charging if your phone or charger starts to get noticeably hot. Then, start charging again after the phone and/or charger have cooled down.
12. Airplane mode should be enabled on the phone
Try putting your phone on airplane mode if your Anker wireless charger blinks blue for no particular reason. During the charging process, some applications may be running in the background at the same time as the charging process starts. You can check this in the settings by going to the app’s settings. Do not run the app in the background if it is not necessary.
If the above solutions do not work, your charger might malfunction or be defective. You may also experience some technical difficulties with your phone. If this is the case, have your phone and charger repaired or replaced.
