What’s the flame symbol on the left side next to the time

It’s a focus symbol. If you set up a focus such as sleep, work, driving, etc, the symbol for that focus setting will appear there. I have the fire symbol for working out and when my phone goes into the working out focus setting, that symbol will appear next to the time.

I have never seen a flame symbol on either side of the time on the iPhone Lock Screen. It may be part of your wallpaper. Change wallpapers and see if it goes away.

To improve understanding of the phenomenon, it would be highly beneficial if you could share a screenshot. Visual representations carry greater impact than written descriptions.

Please remember that this is a public forum, so when attaching a screenshot, please avoid including any personal credentials such as IP addresses, card details, email IDs, Apple IDs, IMEI numbers, serial numbers, phone numbers, order IDs, or any identifiable location information if you are sharing a map.

With the limited information that you have provided, It is hard to even guess the problems faced by you.
