Battery drain on relatively new iphone
So, I've been noticing for a while that my iPhone SE 3 is draining really fast. for example it was at 100% last night when I went to bed and when I got up it was at 92%. Between 9:00AM and 3:00PM it had gone down 12%. Then I did just a bit of reading and after only about 10 minutes it was down to 61%. My max battery capacity is 100% and I've had the phone since September. Despite this, my iPhone is draining much faster on this new iphone than on my 2-year-old ipad, which I have had audio playing on for more than the time I sleep on average, with only about a 5% drain in battery. I charge both of these devices about twice a week or else when the batteries get down into the 40s. What can be going on? Anything I could do that does not involve losing data? Thank you so much in advance. This is much appreciated.
