On board V13.0.6.0.SJBCNXM. Residual battery capacity judging by the application AccuBattery ~ 4000mAh. I don't play or use heavy apps. Most often messengers and calls. But lately, the phone can't handle more than 4 hours of screen time. Although initially, when I bought it new, it lasted more than 7 hours. What is your autonomy?
