Welcome to Adroid Central. How old is your phone? It's possible that your battery health has degraded.

Also, you may want to check things like whether location is set to High Accuracy (use battery saver unless you're actively using navigation), turn off Bluetooth and NFC when not in use, watch your screen brightness (don't keep it too bright).

First, 13 hours isn't bad - most people would be satisfied with 8 hours.

Second, 13 hours and 6 minutes? You watched the percentage as it went down to get the recharge point to the nearest minute? Or you're using the phone until it shuts off? If the latter, you've probably killed the battery. Lithium batteries are not deep discharge batteries, nor do they "like" getting fully charged. You should try to keep the battery between 40% and 80%. Keeping it between 100% and 0% kills it pretty quickly. (Lithium batteries are good for only one reason - they're light. And people want every gram shaved off their phone that's possible. And they want 2 or 3 days of heavy use between charges. And you can't get both in the real world.)
