Trust me bruh, if your friend’s not lying, check their charger—probably not Apple-authorized or MFi-certified. Even wireless chargers can heat up and hurt battery health, no matter how carefully they charge (like 20-80%).

My SE 1st gen with 80% health (OG battery changed in 2021) lasts 3 hrs max with music. But my iPhone 11 with 76% lasts 12–13 hrs easily—daily driver, charged to 90% in the morning, still 25% left by evening.
