New battery diagnosed as "Weak"

[Siddhu1512]

I replaced a new battery for my Note 20 ultra in a Samsung Authorised service center since earlier phone diagnostics showed that battery health is weak and needs replacement . Even after replacement yesterday, when I use diagnostics to check battery life, it still shows "Weak - Action required". Is this a calculation/Software issue or did my service center provide poor quality/ Old battery?

calibrate your battery

I don't understand

let your battery drain completely untill it turns off and charge it till 100% without turning on the phone, turn on the phone incase it shows 99% charge ,charge till 100% and then use your phone untill it drains completely, do this 2 times, once 100% , dial *#9900# and scroll down and click battreystats reset and restart phone

But battery draining rate is also not like a new one... This method may help reset battery status but will it improve the battery health?

Install accu battery and test your actual battery capacity.

That requires long term statistics too... So I hope Samsung members diagnosis will change over time
