Thank you for posting this. Saved me a ton of money buying a new smartphone. I didn't bother detaching the fingerprint sensor though. Just had to be careful not to pull on the back cover too hard. Don't forget to check if the new battery works by charging it before screwing the vertical plate back in! The most challenging part for me was reattaching the power connectors. You need to take your time finding the sweet spot. Don't rush it and push down forcefully or you'll smoosh the dainty little pins inside the connectors and you'll end up with a new battery in a functional phone but with dead power connectors.

If you don't have a heat gun you can roll up a several sheets of damp kitchen paper covered with cling-film and microwave them for 30-40 seconds (until they steam) then lay the hot covered rolls on the seams where you see the heat gun is being used here. Suggest you use gloves to comfortably place the hot paper rolls.

Un tip muy importante,es que antes de pegar la batería a la carcasa,verifiquen conectando el equipo y verificar que cargue correctamente,ya que me sucedió que hize todo y al final no cargaba la batería ,venia con falla de fabrica. Instalé otra y todo bien. Saludos💯
