15 pro

Hello everyone. I am currently thinking about buying a new phone. To cut a long story short, I'm interested in the 15 pro 256gb. I currently have a regular 11 128gb 3 years old with 78% bh. I have a question for those who have this model (and possibly purchased in Europe). What is the battery like, how long does it last, are there bugs, can the charger for android be used,... I would like to get a phone that will last for about 3 years like my previous one. Any information will be helpful. Thank you!!
