Replaced battery but charge only lasts a couple of hours.
A shop replaced the battery on Samsung galaxy s21 plus. Cellphone is over 3 years old and was used a lot daily. The new battery is better than the old one but only good for a couple of hours. I limit charge to 85%, and usually recharge at 20% but now sometimes it goes down to 14% before I notice. Why are replaced batteries so poor or is it something else? I have a new ankor charger and new quality charging cable.
Ist dies eine gute Frage?
