I am facing a serious charging issue with my Nothing Phone (2). Before sleeping, I usually plug in my phone with Smart Charging enabled. Yesterday night, after connecting the charger, the phone clearly showed the charging animation and the charging icon near the battery, indicating it was charging properly. However, when I woke up, the battery was still at 24%. This is not a one-time issue-it has happened around 6 to 9 times, which is extremely frustrating. I am using a proper fast-charging adapter, a good-condition cable, and a working power socket, so there is absolutely no problem with my charger or power source. Despite showing that it is charging, the phone randomly fails to charge overnight. This issue makes Smart Charging unreliable and is unacceptable for a premium device.
