    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[​IMG]

    Welcome to Android Forums @XRN9S :)

    The issues your experiencing could be software or hardware related. From what I understand, the normal discharge should have been 3% but under the same conditions your Redmi discharges at 7%. That would be over twice the normal rate and grounds for concern. I strongly suggest you either return or exchange it while you still can. The old saying "Better safe than sorry" comes to mind

    Thank you for the reply. Would it really be a phone issue? I was able to use the phone normally without turning off the screen with 50% brightness for 19hours. Usage are browsing, youtube, fb, messenger and instagram. Dis not game on it.

    There's nothing abnormal about those apps running in the background. One thing that needs to be taken into accountthe is the user apps Fb, messanger and instagram you've installed. Even if you force stop or kill running service apps like Fb start up again, sometimes with seconds. If your interested , the link below explains Android OS and app fundamentals . It brief but very informative.

    I get that but would that greatly affect the idle discharge? I have not experience that with my old device though.
