iOS 27.2 was released two days ago. Try updating and see what happens. Immediately after an update your iPhone will use a considerable amount of daily battery capacity indexing, syncing data and optimizing data. The may make your device appear sluggish at times because the CPU and GPU are doing those lower level tasks.
You can help speed up the process by plugging your iPhone into a charger, connecting to WiFi and locking it before you go to bed each night for the next 7 days or so. This will allow your device to work through the night and minimize the daytime inconvenience of sluggish performance.

Hi, please look at your Battery settings in the Settings app. What are the top 5 apps consuming your battery capacity? What percentages? Did you recently update to iOS 27.2,and your device is indexing?

I think it's mostly social media, but it's a pretty new phone, so I haven't used social media that much, and the battery still drains so fast. Like, I'll use my phone for maybe 10 minutes, and the battery will drop by a percent. My phone is on iOS 27.1 right now. And what do you mean by indexing?

I see, thank you for the information. Should I give it another week before updating my phone to IOS 27.2? Since I've only had this new phone for about a week, so could it still be running the indexing that you mentioned?
