New to custom roms question

Aug 28, 2021
Hi, I've been thinking about changing from the global miui to lately because a lot of people recommend it. I have a Mi 11 which is a great phone but its battery life isn't so much great, so does the mi 11 battery last longer with I've seen some other post where it seems that the stable version of make the battery last 1 hour longer than what it typically last for me, but I'd like to see how is it on most people.
