Yep, bought my Note 3 on release day 4 plus years ago, battery has just died after 4yrs and 2 months. £8 for new battery, fitted in seconds.
Phone still going strong in my son's hands now. I've stupidly bought a Galaxy S8+ (Nice, realy nice phone, although I dropped and SMASHED (not cracked) screen within two months. It's so easy to drop, it's in a full wrap-around rubberised case now. SAFE!
I think I'm gonna get a simple feature phone next time. I'll be happy with just calls, texts & email on my mobile. I prefer a 7" tablet for everything else. (I'm an old git, as advised by my User-Name.)
