Hi. Recently bought a Xiaomi Redmi Note 9s(Global Version). It has a 5020mah battery. I had the phone for about 6 days already and have been using it normally (browsing, FB, Instagram, shopping app, bit of Youtube and had been able to game on it for approximately 2hrs only every since I got it). I would start charging it around 10-15% to 80-90%. A few days ago I went to take a nap(around 5hrs) and woke up to a 7% battery discharge. Wifi/mobile data and wake screen notification OFF. I master reset the phone. Re-installed everything again. Left the phone for 3hrs(no wifi/data/wake screen notif) and it discharged 3%. Another 7% discharge after leaving the phone idle for 7 hrs (same setting). Reviews I see in Youtube with wifi/data ON overnight the device would discharge 1-3%. As of this writing the phone is running 3hrs of no usage after charging(cleared apps using built in cleaner after charging) but this time connected to wifi and no wake screen notification and it discharged 5%. Is there something wrong with the battery? Or am I just being paranoid cause tomorrow would be the last day I can replace the device with a brand new one. Please help
