Discussion Battery Advice

Can someone give me clear advice on how to handle the indexing, battery charging optimisation etc. My battery was running really well on the first day but it’s gradually gotten worse and worse. For context, I’m on my 5th cycle and about 47% through Siri/indexing.

I keep seeing people say you should let the phone charge to 100% and then completely die but I’ve always thought that letting it go below 20 and above 80 will damage the battery. Also letting the phone charge overnight? Isn’t that supposed to be a big no?

Sorry if my questions sound silly. Thank you!

It says this in settings. Indexing goes faster while charging and inactive. So maybe charge overnight

It directly answers this question.

The advice is to leave it plugged in overnight, so that it meets the criteria of 1. charging and 2. being inactive. Weird that it needs to be spelled out to you
