Battery drain issue in IOS 14.3

Hi Sathyarsn89,

Thank you for posting in Apple Support Communities. From our understanding, since updating to iOS 14.3, your battery drains faster than usual, do we have that right? Check out the tips listed here to Maximizing Battery Life and Lifespan.

You can also check for any app updates: Update apps or use automatic downloads.

You should also take a look at the battery health from Settings > Battery > Battery Health. If it's under 80%, you may want to look into getting the battery replaced.

You may be able to reach out to Apple Support for repair options here: Get Support.

Hope that helps!

this wasn’t helpful because my iPhone 6s is draining 50% at a time with little use. This only started happening after updating to iOS 14.3. My battery health is at 81%.
