Is it true or a myth that charging iPhones up to 80% preserves battery life?
Many online videos and texts say that the ideal is to keep the cell phone with a battery of up to 20% and never charge it beyond 80%. But this is a myth. According to Apple’s website, if you charge up to 75% in one day your iPhone, and the next day use 25%, you have reached 100% of the cycle. What you will be doing is extending the cycle to two days. Using the same logic, you might even have enough more days to drain the battery completely. Remembering that we are talking about lithium-ion batteries.
>>>After laying off more than 70,000 employees, what can tech companies learn from this moment?
Apple makes it clear, see the description below or click on this link (https://www.apple.com/batteries/why-lithium-ion/), that a cycle ends when you use (discharge) an amount equivalent to 100% battery capacity, but not necessarily a charge.
Many people will say, but with this 20% to 80% method, I kept my iPhone close to 100% battery for longer. I can tell you that the same thing happened to my battery without doing this. After the first year, I continued to observe, and it was in the third year the 80% mark was reached. That was the iPhone 8 Plus. Today, at five years old, it is at 79%. Other factors, such as exposure to intense heat or cold, can accelerate battery deterioration.
Apple’s testimonial:
It makes charging easier.
Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle. The capacity of any type of battery will diminish after a certain amount of recharging. With lithium-ion batteries, the capacity diminishes slightly with each complete charge cycle. Apple lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, which varies depending on the product.
The software helps with battery conservation
iPhone battery charges fast up to 80% and slower after that. Would it be proof that we should load up to 80% only? Do not. According to Apple’s support site, the time needed to reach that initial 80% varies depending on your settings and the charged device. The software may limit the charge to 80% if the battery temperature exceeds the recommended limit. This combined process gets you back to using your device immediately and extends battery life.
This does not mean that it only needs to be charged up to 80%, but it is already necessary for you to use the device again. When it gets to that point, the software slows down the electrical current, increasing battery life in the process.
What’s up?
It is not wrong who loads up to 80% and much less who goes up to 100%. They are options. Everyone needs to stay tuned to help their iPhone’s battery life.
