Can you give me good fantasy or sci-fi book recommendations

So. Recently I switched my old phone for new which equates to loosing hundreds of books I'd had open in different tab. Which is sad. A lot of them I was multi reading simultaneously but more were my back ups to read once they are done. Now I can't remember most of their names or chapter no.
Which brings me to my current situation of wondering which book to read now. I'm a huge battle junkie and love having a lot of fight/battle scenes in my books. The more the better. So if you have any books that you know that has good fight scene (a lot of it infact) could you please recommend it to me. I'd absolutely love it.
I'm currently looking for Fantasy and sci-fi novels (webnovels) but other genres are fine too (as long as they are not psychologically dark, and I can't handle too much angst or tragedy; little bit is fine tho)
