Bartery Health drain

I’ve had my iPhone since July and my battery health has stayed at 99% for a good while now yesterday I checked it was the exact same but today when I checked it went down to 96% we have cold weather here but could it be due to cold weather even though I had my phone in my pocket during the entire time?
