Something that might help with battery on iOS 27: turn off Connectivity Assist. It's Wi-Fi Assist with a new name and a new spot in Settings.
When your Wi-Fi gets weak or stops loading, your phone jumps over to cellular to keep things working, then jumps back. On spotty Wi-Fi it can do that over and over. All that back and forth keeps the cellular radio busy, and that drains the battery.
You have to turn it off in two places. First, go to Settings > Wi-Fi, scroll down to Connectivity Assist, and turn it off. Then tap the little (i) next to the network you're on, scroll down to Connectivity Assist again, and turn that one off too.
That second step is the one people miss. I turned off the main switch and it was still on for my home network.

iPhone 15 Pro Max. Battery drain is so severe that I’m having to charge 2-3 times per day…. Same usage, same apps. iOS 27 has an issue. It’s been weeks
This is a perfect example of gaslighting. He was not the only one experiencing this, and it is happening way past the time that an update should be causing it for most of us
💯 lots of gaslighting and rude people in this thread
Your battery is fine. The update is still indexing all of the data on your iPhone and will continue to do so for another few days.
I do the same. Low Power mode all day. Battery drain has been terrible for over three weeks. iOS 27.01 did not help.

After updating to ios 27.2, battery drain is still huge in general mode on my iphone 17
Yet works well for some apps like zee5, hotstar
but for other apps it does not work well
even in idle mode the battery drain is ridiculous
Specifically, what app’s are consuming your daily battery capacity? If it were a hardware or iOS issue it would affect all your apps. What you describing is the effect of software developers not optimizing their apps for the new iOS. This is fairly typical for social media apps and games, but it can affect any app.
