I bought 1 1promax for a month and a half, and now the battery is 95. Is this normal?

Yes, 95% battery health is normal. According to Apple's official instructions, the battery health of iPhone should be above 80%, and 95% of the battery health is beyond the normal range. So the health of your 1 1promax battery is normal. To keep the battery healthy, there are several steps that can be taken: First, try to avoid long-term charging and try to keep the battery charge above 50%; Secondly, try to avoid using it in high temperature environment; Finally, check the health of the battery regularly, find problems in time and deal with them in time. Finally, I want to remind you to avoid using third-party chargers as much as possible, so as not to affect the health of batteries.
