why does my phone stop charging at 80% ？
When develop new products and do marketing research, we will always check the reviews on retail websites.
For our main wireless chargers products, we find that some clients complaint the phone only charge up to 80% when using a wireless charger, and leave a negative review.
Discover the truth behind this common issue, let’s check it from Apple’s official explanation.

If your device stopped charging at 80 percent
Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.
iOS 13 and later use Optimized Battery Charging to slow the rate of battery aging by reducing the time that your iPhone spends fully charged. Your iPhone uses on-device machine learning to understand your daily charging routine so that it can wait until you need to use your iPhone to finish charging past 80 percent.* Optimized Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.
* Information regarding your charging routine is stored only on your iPhone. The information isn’t included in backups and isn’t shared with Apple.
By learning about this intentional limitation, users can better comprehend the benefits it offers in the long run.
1.Seasonal Impact:
It’s worth noting that users often encounter this issue more frequently during the summer months.
However, it’s essential to differentiate between environmental temperatures and device temperature.
Usually, charging in an air-conditioned room is unlikely to cause the limited charging capacity.
2.Device-Specific Factors:
While wireless chargers play a role in charging efficiency, it’s important to consider other factors that may contribute to the issue.
Device-specific problems, such as battery degradation, outdated firmware, or incompatible settings, can hinder the charging process.
1) Battery Health: Over time, batteries can degrade and lose their capacity to hold a full charge. If your phone’s battery health is deteriorating, it may not be able to reach a full 100 percent charge.
2) Wireless Charger: Using a faulty or low-quality charger can affect the charging performance. Ensure that you are using the original or a high-quality wireless charger that are compatible with your phone.
3) Background Apps/Processes: Certain apps or processes running in the background can consume power and slow down the charging process. Close unnecessary apps or perform a device restart to optimize the charging speed.
4) Software Issues: Sometimes, software glitches or bugs can impact the charging performance. Ensure that your phone’s software is up to date and consider performing a software reset if the issue persists.
3. Potential Solutions:
If you’re experiencing the 80% charging limitation, consider the following steps to address the issue:
1) Update your device’s software to the latest version.
2) Restart your phone and try charging it again.
3) Reset your device’s settings to default and reconfigure the wireless charging preferences
5) Place the phone in a well-ventilated environment and allow it to cool down before charging.
6) Use original or high quality chargers to ensure they deliver the proper power and charging quality.
7) Avoid performing a lot of power-hungry operations at the same time, such as playing videos or high-performance games at the same time, which may cause the phone to overheat.
8) If the phone case uses a protective cover or case, try removing it before charging to improve heat dissipation.
9) Consult Phone’s manufacturer Support or visit an authorized service center if the problem persists.
Before leaving negative reviews or assuming that the wireless charger is faulty, it’s crucial to understand the reasons behind your phone’s limited charging capacity.
Apple’s explanation sheds light on the intentional battery protection measures in place to enhance the overall lifespan of your device.
By familiarizing yourself with these factors and exploring potential solutions, you can optimize your wireless charging experience and avoid unnecessary misunderstandings
What we can do to provide a better charging experience when design wireless charger products ?
Designing wireless chargers requires careful consideration to ensure optimal charging performance and prevent issues like overheating that can impede the charging process. By implementing specific measures and adhering to best practices, manufacturers can create wireless chargers that mitigate temperature-related challenges and provide efficient and reliable charging capabilities.
1. Efficient Heat Dissipation
One of the primary causes of charging issues is inadequate heat dissipation. To mitigate this, wireless chargers should incorporate effective heat sink designs, such as aluminum or copper components, to absorb and dissipate heat efficiently.
Additionally, incorporating ventilation channels or fans can help maintain a cooler operating temperature, preventing the charger from reaching excessive heat levels.
2. Temperature Monitoring and Regulation
Integrating temperature sensors within the wireless charger allows for real-time monitoring of the charging process. By continuously monitoring the temperature, the charger can adjust its power output or even temporarily pause charging if the temperature exceeds a certain threshold. This feature protects both the charger and the device being charged from potential overheating risks.
3. Smart Charging Algorithms:
Implementing intelligent charging algorithms can optimize the charging process and prevent excessive heat buildup. These algorithms regulate the charging current and voltage to ensure efficient power transfer while minimizing energy loss and heat generation.
By dynamically adjusting the charging parameters based on the device’s requirements and the charging conditions, the charger can maintain a balanced temperature during the charging process.
4. Quality Components and Materials
It’s crucial to use high-quality components and materials to build the wireless chargers, in order to maintain optimal performance and prevent overheating.
Quality components, like high-grade coils, capacitors, and power management ICs, can help minimize energy loss and improve charging efficiency.
Furthermore, using heat-resistant materials for the charger’s housing and internal components can enhance heat dissipation and overall durability.
5.Thorough Testing and Certification
Before launching a wireless charger, manufacturers should conduct rigorous testing to ensure its reliability, safety, and compatibility. Independent certification bodies, such as FCC, Qi, UL, CE, RoHS etc., can assess the charger’s performance and safety standards.
If the product does not pass the certification, engineers will make corrections until it meets the certification requirements, which will ensure that the product meets the requirements of local market regulations, and consumers can buy with confidence.
By implementing effective heat dissipation mechanisms, incorporating temperature monitoring and regulation features, utilizing smart charging algorithms, using quality components and materials, and conducting thorough testing and certification, manufacturers can create wireless chargers that prevent overheating and charging issues.
These measures enhance the user experience, improve product reliability, and ensure the successful charging of devices without disruptions caused by excessive heat
