Did you Force Restart your iPhone after you updated it? If no, you should do this after iOS updates --> Force restart iPhone - Apple Support
Wifi and Bluetooth are not the biggest users of power. Cellular communication usually is. Is your phone set for 5G Auto, in Settings > Cellular > Cellular Data Options?
You're welcome. Just an FYI that it is not uncommon for battery life to suffer after an iOS update. Keep in mind the phone is reindexing millions of bytes of data after every update. Force Restarting is advisable after an update to kill things, which may be running in the background, which can affect battery life.
While I was trying to attempt what you recommended, my battery fell from 29% to 21%. anyway, I have now force rebooted it as per your recommendation, and I will now monitor my phone all day tomorrow and will let you know if there is a difference. Additionally, yes I confirm 5G auto is ON on my phone. Thanks mate.
I additionally have other issues post this update. Some app buttons do not respond and some calls gets disconnected. I am using 2 numbers one is international roaming and that’s acting super wierd!!! I wish I had not updated from 18 to 18.0.1 as 18 was working really well for me.
If my network only supports upto LTE, will selecting 5g auto in settings make the phone search for 5g network and consume additional power?
also, if i select LTE and move to a location where only 2g/3g is available, will the phone auto switch to 2g/3g?
Issue resolved.
thank you very much mate..
I'm glad the issue is now resolved. If you don't have access to 5G at all, don't set it to 5G Auto.
Battery issue after. 18.0.1 on iphone 15 pro max
