Last week I bought a Redmi Note 9 Pro phone, which is supposed to have the fast charging. Unfortunately, when I charge my phone, it takes more than 7 hours to fully charge (I use the original charger). On the Ampere app which measures charging speed, it says it only charge at speed of 410 mA. My MIUI current version is MIUI Global 11.0.1, and in the settings it does not offer me a possibility to update it (says "no new updates available"). Could this be the reason for the slow charging speed?
Thank you for your help.
