2. Hello, if you buy a new Apple mobile phone, it means this is not normal. If the service life of your mobile phone becomes 95 after a period of use, then this is very normal. See for yourself what kind of situation your mobile phone belongs to.
3. This is normal. Batteries are consumables. It is normal that the battery loss of mobile phones does not exceed 20% a year. As long as the battery loss efficiency of the mobile phone is within this range, it is normal. Moreover, if the mobile phone is still under warranty and the battery efficiency is less than 80%, it is possible to replace the battery for free after going to Apple.
4. It's normal. My XS battery is 95% healthy for four months, because I often play with chickens. When the battery is 2%, I play while charging. It is strange that the battery is not worn out. Mobile phones are for use. Replace the battery if it doesn't work. If not, don't worry too much about getting a new mobile phone.
5. The new IPHONE has been used for one month, and the battery is 99%. This situation is normal, and it is normal to have losses. And it will take you a long time to get from 99% to 98%, at least a few months. You can wait and see.
