Apple has confirmed that the iPhone 15 battery has received important improvements that affect its life, so much so that it can achieve compared to the battery of the iPhone 14 doubles its lifespan. To better understand this, we need to consider what happens to the iPhone battery over time and charge cycles and How will this affect users?

What happens to the battery when we charge the smartphone

After completing charging cycles, the smartphone battery loses capacity. This means that the more we use and charge the battery, the faster it degrades and the more it loses its retention capacity. The less retention capacity is left, the less it lasts, and therefore The less autonomy our smartphone will have and the more we will have to charge it.

With the iPhone 14 battery, Apple said it was designed to retain 80% capacity after completing 500 charge cycles. This means that if we charge our smartphone on average once every two days, the battery It lasts almost three years with a retention capacity of more than 80%.

When the retention capacity drops below 80%, the loss of autonomy becomes very noticeable, and this makes many users decide to replace the battery and give your smartphone a second life. This is why battery life during the first stretch is so important, as it can make the biggest difference in the user experience and the distance between the purchase of the terminal and the first battery change.

Why the iPhone 15 battery upgrade is so important

On the other hand, the iPhone 15 battery is designed to maintain 80% of its retention capacity for 1,000 charge cycles, which means that if we charge the iPhone in this case on average once every two days It would take nearly six years to drop below 80% retention capacitythat means it would have twice the lifespan.

Improvement is important, no doubt about it. However, it is important that the values ​​Apple gives are the ones registered by the company in optimal conditions, and therefore may vary (for the worse) when conditions of use and loading are not optimal. In my case, I perfectly remember that the iPhone 8 Plus battery I had took almost four years to drop below 80% retention capacity because I was charging it once every two or three days.
