Think I'll go with Accubattery app as it's supposed to work out battery capacity and wear from charge cycles. That and it shows a healthier battery than the Samsung info app.
On the subject of battery how do you charge your phones. Experts reckon little and often not letting battery get too low and charging only to 80 to 85%. I've always charged mine overnight on a wireless pad but not at fast charge. I've been trying out charging to 85% before bed then leaving off charge overnight then maybe give it a top up if opportunity presents. Seems a bit of a pain though. Slap it on charge pad overnight and then good for the next day - job done, seems my preferred method. Battery is going to wear. If keep phone long enough a new battery won't be too expensive though fitting to a Samsung (S9+ for me now) maybe best left to someone who knows what they're doing.
