Battery drain in iOS 14.7.1

Rachelle ~ The long process of applying an iOS update can kill a weak, aging battery...

Is your iPhone 6S Plus's battery still the original one?

And what's the Maximum Capacity % here?...

Settings > Battery > Battery Health

Thanks for your post, it’s a pity the new battery hasn’t solved the problem. I was thinking of replacing the battery in my 6s but don’t think I’ll bother now. Wish I’d not upgraded to 14.7.1 following advice from an Apple person. My battery percentage goes into freefall after charging.

Might have stumbled on something that's had a benefit to my phone. I turned off participation in the Find my network and my battery has seemed a lot more stable since (Settings / Find My / Find My iPhone, and disable just the option Find My network, leaving the other two options enabled). For those that don't know, this feature is an update to the old offline finding mode that existed before iOS 14.6 that now allows Airtags and other third party locators to work. Opting out does disable the ability to find a lost iPhone that's not connected to the internet, but doesn't change the ability to Find My iPhone for devices that are connected.

If you're willing to try turning this off for a day or two, would be interested to see if this helps battery drain for anyone else?

I now have to keep mine plugged in to use my phone because it keeps shutting down from battery problems since this update. Mines been all over the place but not holding charge or goes from 100 percent to 1 percent. Apple acted like they knew nothi ng of this when i went to support

My batteries health was great. Ive never had a problem eith it at all and was performing 100 percent peak capacity. I do slot of music, play games, text alot, my battery was fine until i downloaded new update and it immediately went straight down and bad thing is i only updated because i needed apple to check another problem i was having and they want u to update to date

Just updated to 14.8 this morning, now my iPhone 11 has drained its battery and its mophie battery back in 3-4 hours, twice today. Up until last night it was lasting about 10 hours before needing to turn on the battery back.

Last week I restored my iPhone as a new device using iTunes (I did a backup but installed all my apps manually). At least it fixed wi fi 5Ghz issue. Before I had low speed 5Ghz WiFi. Overnight drain didn’t changed: still 8%.

But yesterday I turned off find my network in find my and today overnight I lost only 2%

need to check several days (with on/off)

but I recommend to restore your device using iTunes if you have any problems (this is different than reset settings)

I understand the frustration. You can use https://www.apple.com/feedback/ to report that directly to Apple. Good luck.

Your battery is totally degraded. Nothing to do with the update.

You still have not given us your battery health %
