I’m curious as to why Home Screen and Find My keeps draining my battery, but only at night. In the pic posted between 9am and 9pm my battery went from roughly 75% to just under 50%. But then between 9pm and early morning the battery completely discharged even though I’m not using it for most of this period. This is typical. What’s different at night ? Is this a bug ?

Your iPhone (or any smartphone) uses power continuously, even overnight. The lock screen uses power every time you receive a notification, as it must turn on to process the notification. Find My uses energy to determine its position, and also to respond to requests for location from any devices that you share your location with.
You should be charging your phone overnight with Battery Charging Optimization turned on. And you are letting your battery get much to low; over time, that will shorten the useful life of the battery. The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

I spoke to customer service and all diagnostics test went well. What ended up addressing the problem was me un pairing and then pairing the watch again to my phone. That cleared up whatever software issues existed with me updating to watch OS 9 since the phone worked great during last night (used less than 20% battery).
Hi jlslu,
Thank you for posting in Apple Support Communities! There are a few tips on settings you can implement in order to maximize your battery life.
You can find those tips here: Batteries - Maximizing Performance - Apple
Be sure that your device is up to date running the latest iOS ( currently iOS 16.0.3). To check for any updates that may need to be installed and install them:
Update your iPhone or iPad - Apple Support
Hope that help!
If you are going to wear your watch overnight charge it for an hour or so before you go to sleep.
I understand your points with respect to my phone but how do I achieve this with the watch? Overnight is where I have it on to calculate sleep times etc. Updating my watch to iOS 9 has resulted in a complete battery drain overnight.. and this is with sleep focus where screen wake up is off and there are no notifications etc
That’s what I did. Went to bed with it fully charged woke up to find it just under 10%.
Then there’s something wrong; it shouldn’t use that much overnight. Are you streaming music with it, or anything else that uses data or energy.
