Since I upgraded to IOS 17.1.1, I’ve received this notification in my settings «Your iPhone has been used more than usual since upgrading iOS, which may affect battery life» and I have in deed noticed that my battery drains incredibly fast compared to before.
what can I do to bring it back to normal ?

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns and not iOS version updates. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.
Protect & Prolong the Life of your iPhone's Battery:
Updating iOS on your iPhone should typically not alter the fundamental functionality of the device. It's possible that there were underlying issues before this update, which you might not have been aware of previously or might not have noticed.
In general, iOS updates are designed to enhance the user experience, improve security, and fix bugs, rather than introducing major disruptions to core features. The reported issue of the screen flickering and displaying a white screen after an update is likely caused by factors that are not explicitly mentioned in your post.
iOS updates primarily focus on improving system performance, introducing new features, fixing bugs, and enhancing security. They are designed to preserve your personal data, settings, and information intact.
During an iOS update, your device's operating system is upgraded, but your personal data, such as contacts, photos, messages, and other information, should remain unchanged. However, it's always a good practice to perform a backup of your device before any major update to ensure that your data is safely stored.
It's important to note that while an iOS update itself should not alter personal details, it's possible that certain features or settings may be adjusted or improved with the update. In such cases, you may need to review and adjust specific settings to match your preferences after the update.
Always make sure to read and understand the update details provided by Apple before proceeding with an iOS update, and follow best practices such as backing up your device to minimize any potential risks or complications.
See what each update does: About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...
What made this observation rather objective is that for instance, overnight my battery life could remain the same or go down by 1% to 3% maximum, now it is going down by up to 10%. ( no background app refresh whatsoever)
And for more details, my battery health is at 100% and my iPhone is newly purchased ( a week ago ).
Not helpful as it’s definitely an iOS 17.1.1 issue as I have seen c600 ppl on another forum complain about same issue so couldn’t be an underlying issue for everyone so please sort out this issue- let’s see if you can sort out the issue faster than my battery drains every day
You are assuming that everyone is affected. Many millions of users are not. If they were, the support forums would be flooded with posts and the topic would be appearing on the evening news.
iOS 17.2 is available if you want to keep your phone up to date.
If you are really concerned, make an appointment at the Apple Store or take the phone to an authorized Apple service shop to let them test the battery. You can find a list of authorized shops in your are using this link:
Good luck
I have also noticed since upgrading to iOS 17, that the battery life on my iPhone 12 Pro is not lasting as long as it used to. Come on Apple technicians figure this out because no one‘s happy.
