My 15 pro Max is losing battery very quickly

Battery is draining very very quickly for the past 3-4 days. Im not using features of Apple Intelligence and i dont play any games. Like when i was about to sleep my battery percewas at 40% and after 9-10 hours when i wake up it is less than 20%. This is ridiculous!

What's the battery health?


Was it on the charger while you slept? If it is a battery reaching the end of its life (like mine) it can easily drop that much just sitting around untouched for 10 hours.


Read this support article about iPhone battery and performance to learn about the battery health feature and what is considered normal performance --> iPhone battery and performance - Apple Support

To see the feature go to: Settings > Battery > Battery Health


"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." A degraded battery may display the notice: "Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity." If it is not at or above 80% "normal", consider contacting Apple about a battery replacement. --> iPhone Battery Replacement - Apple Support
