@miturinhachidori5026 the battery lasted for 2 whole days for the past 5 years with fast charge and heavy use of youtube/music reproduction.
Althrough I don't use it for games that much.
Nowdays it lasts for a day and a half, with heavy usage making it last a bit less than a day.
In terms of how it feels, it's nice, I used a lot of features I've never used before, and it's responsive.
Hope this helps.
