CR2477 battery

Knowledge point: Will wireless charging make mobile phone CR2477 battery shorter-lived?

Wireless charging was born after smartphones. When it first appeared, it was accompanied by various limitations, but with the advancement of technology, problems such as the need for precise placement or slow charging speeds have disappeared, and it has been widely sought after by technology fans. Samsung was the first to adopt wireless charging technology for Galaxy phones, and since Apple (iPhone) also adopted this technology last year, the popularity of wireless charging has remained high. With the widespread adoption of the Qi standard, the Wireless Power Alliance also seems to have won a potentially thorny standard battle. But with the rise of wireless charging, some people have begun to suspect its hidden costs: wireless charging may degrade battery performance faster than traditional wired charging. We decided to investigate and see if this assumption is true. 1. The usable power limit of mobile phone CR2477 battery The design of the energy storage size in the battery by the battery manufacturer determines the amount of power we can use. The manufacturer sets a fixed upper cutoff voltage and a lower cutoff voltage, and implements electrical cycling between the two voltage ranges. As long as we choose the right voltage range, we can cycle the battery thousands of times. Whether we use a wireless charger or a wired charger, even if we leave the phone on the wireless charging pad for a long time or leave it on all night, we cannot exceed the manufacturer's energy limit or discharge the power beyond the lower cut-off limit specified by the manufacturer. In other words, we cannot overcharge or discharge the battery too much. 2. Battery cycle limit Different CR2477 battery have different standards, but it is generally believed that the performance of the battery will degrade after a certain number of charging cycles. For example, in Apple's iPhone devices, the battery is designed to retain up to 80% of its original capacity after 500 full charging cycles. One of the current criticisms of wireless charging is that the mobile phone battery under wired charging will get a "rest" compared to charging on a wireless charging pad. Therefore, in the case of wireless charging, the battery will go through the limited cycle faster and degrade faster. But is this true? This is a misconception. If we want to reduce the charging cycle, the easiest way is to reduce the amount of power we use. A rogue application that is constantly sending data in the background, or in an area with poor signal, the phone is trying to improve the connection signal, these may be more harmful to our battery life than our charging habits. 3. Potential advantages of wireless charging While there doesn't seem to be any evidence that wireless charging degrades smartphone CR2477 battery faster than wired charging, there are some tangible benefits. For example, there is less wear on the charging port, which often leads to failures and requires repair, so wireless charging is ideal for public charging facilities in hotels, cars, restaurants and trains. There is also a saying that it is better to keep our CR2477 battery partially charged. We investigated whether it is possible to let smartphones charge at night, and the advice we got was that if the battery is kept between 50% and 80%, the battery life will be longer. By continuously charging the phone during the day instead of letting the phone battery drop below 50%, we can extend the life of the battery. According to our research, when the battery is limited to 50% instead of 100%, the battery life will actually increase by 4 times. 4. Is the phone hot? If our phone is charging wirelessly or is not placed correctly on the charging pad, we may notice that the phone becomes hotter. Most mobile phone CR2477 battery are damaged by exposure to high temperatures, which is why we make sure that the charger is Qi-standard. Certified devices undergo rigorous testing to ensure safety, interoperability, and energy efficiency, which helps ensure that temperatures don't rise to dangerous or harmful levels. If we want our smartphone CR2477 battery to last as long as possible, it's the temperature that we should be concerned about, not the regular charging method. Many high-quality wireless chargers have fans and cooling systems built into them. But this isn't a problem limited to wireless charging; phones can also heat up when they're charging wired. To prevent your phone from overheating, don't leave it on a windowsill or in your car in direct sunlight, don't play graphics-intensive games while your phone is charging, and don't use uncertified wireless charging pads or wired chargers. Phone battery life depends a lot on the manufacturing process and settings made by the phone manufacturer, as well as how we use our phones, but as charging speeds and battery capacities continue to improve, battery life could become a potential issue. We've already noted that wired chargers are rapidly improving in terms of fast charging technology, but this has also caused the phone to heat up, and charging in this way can also be harmful to the battery, but that's another question for another time. Ultimately, the answer to the question of whether wireless charging reduces battery life is no, wireless charging does not degrade the battery faster.
