Hey, recently had the battery replaced on my MBP 2018 15-inch. The new battery now lasts 3 hours and 35 minutes on a full charge. is that normal? Back when I bought the Mac it easily lasted 7 hours. What's causing the drain? I only have Safari on, but the drain on Sonoma is horrible. What gives?

Then talk to iFixit and explain the situation to them. It sounds like you received a bad battery or the "local company" maybe didn't install the battery you supplied.
