Why Is My Phone Not Charging? Common Causes and How the Right Phone Case Can Help

Suddenly your phone won't charge? Or it doesn't seem to be receiving any power after you've tried charging it? When these situations occur, our first thought is usually, "Why isn't my phone charging?" Many people stop troubleshooting after checking their phone and the power source, but today we want to introduce another item that might affect phone charging—the phone case.

More and more people are now using wireless charging to charge their phones, making phone cases a crucial element. A suitable phone case can greatly assist with wireless charging, while a poor-quality case can hinder the process. Therefore, a suitable phone case can help prevent your phone from failing to charge.

Common reasons why a mobile phone won't charge

The problem lies with the phone itself.

1. Dust buildup in the charging port. Like AirPods charging ports, mobile phone charging ports, when exposed to air for extended periods, accumulate dust and lint, leading to poor contact. This poor contact is a major cause of phones failing to charge.To improve this situation, you can use toothpicks or tissues to clean it, but avoid using metal objects or damp cloths. Another less official method is to play upbeat music to shake dust and other debris out of the charging port.
2. System or background lag. Every mobile phone has its own power management system, which is responsible for protecting the phone during charging and adjusting various data. Therefore, if this power management system malfunctions, the phone will be unable to charge properly.
   Besides system malfunctions, another possibility is that too many background applications are causing the phone to lag. In this case, the phone may become slow and fail to detect charging in time. Alternatively, the phone may overheat, triggering its self-protection mechanism and pausing the charging process.
3. Battery aging leads to decreased charging performance. Battery aging is an unavoidable cause of charging problems. Long-term phone use, habitually using the phone while charging, or other poor phone usage habits can all contribute to battery aging. Over time, this can lead to the phone becoming unable to charge.

External reasons for mobile phone

1. The charging cable is faulty. Using an incompatible charging cable or having broken internal wires can also cause charging failure. You can troubleshoot by replacing the charging cable. For daily use, we also recommend using official charging cables or cables that have passed safety certification.
2. A malfunctioning power supply. A faulty socket or a damaged charging adapter can also prevent your phone from charging. Try replacing the charging adapter and socket to troubleshoot and confirm the power supply status. When charging, you can check the phone's charging protocol to determine the specific wattage of the plug. Using a compatible plug can also protect the phone's power supply and extend its lifespan.

Reasons why a phone doesn't charge during wireless charging

• The phone case is too thick. Wireless charging works by using a magnetic field to transfer electrical energy from the charger to the phone's battery. During this process, the wireless charger creates its own energy zone, within which the phone's wireless charging function can operate normally. Therefore, an overly thick phone case can interfere with the phone's reception of power from the wireless charger, causing intermittent charging or even interruptions.
• The magnetic ring inside the phone case may be of poor quality or poorly designed. Wireless charging transfers power to the phone through electromagnetic induction, so the magnetic ring on the phone case will significantly affect it. If the magnetic ring is made of an unsuitable metal material, it will affect the magnetic field of the wireless charger, leading to abnormal charging.
  Besides the material of the magnetic ring, its position is also crucial. Inaccurate positioning can cause the phone and wireless charger to misalign, reducing charging efficiency and potentially leading to overheating or charging failure. An overly thick magnetic ring can also affect the wireless charger's magnetic field. Wireless charging is highly sensitive to distance; if the phone is too far from the charger, it may also fail to charge.
• The phone is not placed in the optimal charging position. One inconvenience of non-magnetic wireless charging is that the charging position needs to be manually adjusted. If your phone is not adjusted to the optimal position, it is easy to experience unsuccessful charging or low charging efficiency and slow speed.

How a suitable phone case can help with wireless charging

1. It features a high-quality magnetic ring. For wireless charging phone cases, the built-in magnetic ring is crucial. This ring needs to be of high quality and placed in a suitable position within the case. The magnetic ring should be directly aligned with the phone's battery to ensure that charging will not be abnormal due to misalignment.
   At the same time, the magnetic ring must be made of a suitable metal with good magnetic permeability and no permanent or weak magnetism. It must be able to guide the magnetic field without interfering with the wireless charging process. For example, soft magnetic stainless steel or soft magnets are suitable.
2. A thinner phone case is preferable. Wireless charging involves electromagnetic induction, and the energy field created by the charging station has a certain distance. The distance between the wireless charger and the phone should be within 5 millimeters. Therefore, the phone case we choose should not exceed 5 millimeters to avoid affecting the wireless charging process.

Good habits for ensuring your phone charges properly

Clean your phone's charging port regularly. Make it a habit to clean your phone's charging port periodically to prevent lint and dust from affecting the charging process.

Use a dedicated charging cable and adapter. To ensure a smooth charging process and reduce battery wear, choose a charging cable and adapter that are well-suited for your phone, minimizing the impact of external factors on the charging process.

Choose a suitable wireless charging phone case. We can divide this type of phone case into two categories.

• The first type is for Android phones, which are compatible with wireless charging but lack magnetic charging functionality. For these phones, to better utilize wireless charging, you'll need to purchase a phone case with magnetic charging capabilities. The magnetic function allows for precise positioning of the wireless charger and phone, ensuring accurate and efficient power transfer between them.
• For example, the aulumu Samsung series phone cases. Samsung phones don't have built-in magnetic rings; to use the precise magnetic function, you need a phone case with a magnetic ring. aulumu Samsung series phone cases all have built-in magnetic rings, and the overall thickness of the case is designed to be within 5mm. The position of the magnetic ring also matches the phone's battery position, ensuring that the case assists rather than hinders the phone's charging process.
• The second type is MagSafe for iPhone. iPhone 12 and later models have a built-in magnetic ring inside the casing. This ring precisely positions the battery during wireless charging, ensuring alignment throughout the entire charging process and preventing misalignment that could interrupt charging. For iPhone cases, the magnetic ring is a bonus. The double magnetic attraction further secures the phone to the wireless charging pad.

  aulumu iPhone cases all come with magnetic rings that help your phone wirelessly charge.

Conclusion

If your phone won't charge, don't worry. First, check the phone itself, then look for external causes. If both are ruled out, then you should check if the phone case is causing the charging problem. Choosing a good phone case can greatly assist your phone's charging process.
