Which client do you use? Damus? Amethyst? It’s known issue, discussed on here. Try decreasing your number of relays. #[3]​ better equip to help ya answer

@ Will is Damus

@ Vitor Pamplona is Amethyst

On Damus test flight you can disable animations & images.. but that still does not account for all your 19 relays pulling huge amounts data. Decrease your relays to also help battery life. #[2]​ can help ya get into test flight, he super smart w that stuff 🫶. Hope that helps
