The newly bought xsmax battery has a monthly efficiency of less than 94. Is it the cold weather?

The efficiency of this battery dropped to 94% in less than a month, which may be mostly due to the product itself. Cold weather is only a small part of the influencing factors. Of course, this ratio has dropped to 94% a month, which is abnormal. A large part of the reason is that your battery may not be the original battery itself, which leads to this situation. Or the phone itself is not a new phone.

Moreover, the battery itself is a consumable and consumes quickly. In the case of heavy use, it will consume faster, so when using it, we should pay attention to some daily maintenance and correct usage habits.
