It arrived very quickly in secure packaging, but it was completely discharged. After installation, it took a long time to charge and for the device to turn on. Since then, in Samsung's diagnostics, it shows that a problem was detected with the battery and that it is weak. I waited for it to complete a few charging cycles (in case it was a memory issue with the device and it would recover), but two months later there has been no improvement.

I purchased a new battery for my phone, but 2 weeks later the system on my phone told me to replace the battery because it's not functioning correctly. Very disappointing.
