Phone batteries are just a year or two affair and you are in year 4 or 5. There are folk that battle (argue) it's not the battery. They are often best left to ponder.
Am familiar with android and samsung and have used various handsets over the years. I got a N4 the other day from CEX here in the UK for £190. 2 year warranty. It's a great phone. Now IK the battery won't be that great as its used. But I have this issue I have encountered on samsung phones from the 2013-2014 era. It's this weird issue where when you charge it, it won't go beyond a certain number, but once you restart it or take the battery out it starts charging again or says it is 100%.
I'm sure this is a software issue as the battery is fine I think - won't spin or anything . Is this just an overreaction? Am I okay to not bother taking the battery out and restarting it, and just leave it, as it is quite irritating to have to keep on doing it.
I'm open to all opinions.
