    I think after the ios 12.4 update the battery life is enhanced than it used to be. Usually, I charging my iPhone 8 plus until it fully charged and keep it in the bed when I sleeping at the night. But when I checked the battery in the morning there is less than 50% is left. I wonder why is this happening and how to fix it.

    Thoughts?

    I would try to do a hard rest to clear out any caches that might be causing issues.

    Press vol up, then vol down, then press and hold the sleep/awake button until you see the Apple logo.

    Make sure you are not plugged in when you do so.

    Try charging it with the “Optimize Battery Charging” option disabled in the battery health settings.

    Experienced severe battery drain on my iPhone 8 Plus too after updating to 12.4, at least 40% drained after fully charged the previous night. Already turned off background app refresh, bluetooth, Wifi to no avail.
