The delivery was great and very fast. However, the battery is not living up to my expectations. I got this battery to replace the original battery in my One Plus Pro which wasn't really holding its charge for a working day, ie I took it off the charger at 8am and it lost charge by 4pm. I was really expecting that this new battery would improve things a lot, that I wouldnt have to charge it every single evening, However, the new battery from you is as bad if not worse, than the old battery. So is that as good as it gets, ? What can I do if I am not happy with the ability of this new battery to hold its charge?
