hi. I received my new s21 4 days ago and I have charged it 4 times!!! I followed every instruction manual going. im livid as I have spent soooo much money. tv advert bosts about the battery, I wouldn't!!! any advice
First 4 days is always when the battery is a little bit nuts. It is learning your usage patterns, if you see no improvement after the first week then might be worth phoning Samsung and telling them whats happening.
