I am curious of how this diagnosis decide if a battery is weak or not. Laptop batteries had battery info app that lists the Original capacity and also show the current deteriorated max capacity. This diagnosis is so simple that stating "weak" without detailing any more info. 😆 Very convincing I guess. Battery does deteriorate over time, but this diagnosis tool should at least show some facts supporting that claim. So that user can decide if the deteriorated capacity is worth to chg or not. imagine its 3000mah still have 2700mah but then they gonna claim it as weak. That is still 90% out of the Factory New full capacity. How many "real" 3000mah replacement batteries is out there?

I rmb sending my S7 edge to samsung for a battery chg last year, costing around Rm190 including waterproof test. Using app called "Phone Info ☆SAM☆", the new replaced battery health was only 88% out of the 100% rated 3600mah. This 88% was replacing the original deteriorated battery that has around 76% health lol.

So funny is even samsung centre also cannot solved our problem. Even we change battery also no testing checking any problem make it battery weak. Because they just help what we need to change only. If without warranty better outside mobiles repair. Same status weak but that is not samsung centre repairs, i accept and cheaper price.

I guess if ur battery life improved then it is working as intended. My case, I noticed my 100~90% dropped slower than using my older battery so I would say after changing, it did improve. Also, samsung service centre will charge water resistant testing for rm80 so it sure adds to the cost. But justifiable since the phone is restored back to factory spec resistance.
