How normal is the life of Apple X battery?

It is normal. More than a year is a bit bad, all below 90. But the battery drops quickly, then stabilizes for several months, then drops again, and next time it may be over 80. Then it is generally suggested that if it is below 80, it is best to change it. It is estimated that about two and a half years is a hurdle. It is normal. More than a year is a bit bad, all below 90.

Generally, after using a mobile phone for a long time, you will feel that the battery is not durable and you will want to know what the battery capacity of the mobile phone is. In fact, there are many softwares that can check the battery capacity, such as AISI Assistant and pp Assistant, all of which can be checked accurately. Since Apple has added the battery health function to the iOS system, there should be many iPhone users who like to check the battery health of their mobile phones in their spare time, and I am one of them. To some extent, although this function can clearly display the use status of the battery, it will make users feel "anxious" more or less. According to the theoretical reference value given by Apple, the maximum capacity of the iPhone battery is less than 80%, which means that the battery can no longer provide the necessary peak power for the iPhone. At the same time, the battery health will enter the maintenance state, telling you that it is time to replace the battery.
