Find My battery drain after 16.3 upgrade

These standard hint are useless. I also charge my iPad to 100%, close my Magic Keyboard in „do not disturb“ focus, after one day of no usage the battery is almost empty. I check the battery usage, only “find my” app is consuming 2-3% each hour, no other app is listed as consumer. When I disable Bluetooth, everything is fine. I guess is has something to do with my 3 AirTags around me attached on my bike, wallet and keys. All AirTags are on the latest firmware.

I had this after updating to 16.3 but restarting my devices fixed it. This might also be of help to you all

Protect & Prolong life of your iPhone's Battery:

1. About the battery usage on your iPhone, iPad, and iPod touch ...
2. Batteries - Maximising Performance - Apple (IN)
3. iPhone Battery and Performance

Try some of these options too.

1. Avoid Screen Mirroring
2. Put on Low Power Mode
3. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
4. Put Auto Answer Off
5. Disable Push notifications for apps you do not use often
6. Keep your iPhone Face down to prevent notifications to light up screen
7. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
8. Manually lower brightness from Control Center
9. If you Want to watch continuous Video. Stream it on TV or a Monitor
10. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
11. Location services to be allowed only while using the app
12. Set your iPhone to fetch email and calendar data from internet less frequently
13. Turning off Background App Refresh 
14. Charge before it drops below 20-30%
15. Try connecting to trusted Wifi where ever available in stead of Cellular
16. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
17. Switch off Wifi & Bluetooth while in Roaming or Not in Range
18. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
19. Periodically Check your Battery Health (Settings > Battery > Battery Health)

I’ve been having both Find My (primarily, biggest culprit) and now Siri as the only two background apps running down both my iPhone 13 Pro and iPad mini 6 batteries ever since upgrading from iOS 15.7.2 directly to iOS 16.2, and not improved with the iOS 16.3 update. This is with background app refresh disabled, Listen for Hey Siri disabled, and Find My fully configured with two AirTags and the ability to track my own watch/phone with my wife and I sharing each other’s location. Unpairing AirTags and disabling shared tracking did not resolve them, and I’ve naturally restarted all devices and even reset iOS Network Configurations to no avail. Further, graphical animation lag & stutter are persistent and unacceptable for these still like-new devices <2 year on. iOS 16 was hardly worth the “upgrade,” but does Apple even care?

iPad 16.3 battery is draining faster than 16.2. Every time i wake up my iPad 1% is gone. New to apple a big mistake to upgrade to 16.3 Hope to see an update soon. Find my iPad off. Only using notability and pomodoro app. Usage is minimal no vedio content.

Facing similar issue on my newly bought device iPhone 13 after updating to iOS 16.3 my battery drained overnight from 60% to 20%. facing really bad experience with my new device, don't know when they are going to fix this issue, as it's affecting device battery health and sure thing is apple not going to fix battery health for free, we need a battery performance update for this really soon.

My husband and I updated our I phone and Apple Watches with the 16.3 and same problem. Can’t wear my watch for only a few hours and is dead. Same with our phones. just tried to call Apple support and they cut us off when we told them about the problem. Not very good publicity for Apple. We have loved our watches. My husbands watch is only 1 month old.

I have the exact issue. In 24 hours of not using my iPad it went from 100% to 60% with FindMy, Siri and Home Accessories being the only things showing up in the Battery Section! I’ve tried a number of things and nothing helps

Same and infuriating problem with my 2021 iPhone SE. I turned off several valuable features, which helped somewhat, but the battery life is significantly reduced. The update affected my iPad Air 5th gen to a lesser degree. Come on Apple, a year-old iPhone should not have this kind of battery drain and turning off features that I previously used to accommodate your lousy update is a poor solution.

I've completed every suggestion out in the universe (including the ones in this thread)....using Apple charger and cord. Double checked connections. Removed apps that I am not using. Battery has taken a major dump since this update.

My iPhone 13Pro was down to 20% at the end of the evening, with normal usage. Battery-settings showed that Google Maps consumed 26% (23 mins background) and I have hardly been out of the house today. Next 14% was Spotify.

Hello. I have the same problem after updating to 16.3. My iPhone 12 mini started to drain very quickly like crazy. Also I noticed that after updating iPhone stop changing don’t disturb mode automagically at the morning. I hope Apple now about this issue.

Well I had the worst experience at istore today. I have been noticing a due battery drain in my iPhone 12. He claims it software problem so I rebooted my phone and apparently see what happens if it doesn’t even though my phone has a warranty they won’t change it for a new one . I left there and I just just got home after a hour drive no use of the phone and it’s again fallen to 70% from 100. It’s just a disappointing to be treated like this when there is clearly a problem but if I were to just go and buy a new phone without reporting a problem they would be more helpful. Just a shame

Mines too!! THIS IS AWFUL! I might need to go back to an android
