The phone runs the Android Pie operating system-based MIUI 10 with Poco launcher loaded on top of it. Like other Xiaomi smartphones, the Redmi K20 Pro also sends some unwanted advertisements and notifications via pre-installed apps. However, the frequency of such notifications and advertisements is relatively low. There is also a provision to disable these random ads and notifications, but the process requires some time and effort.
Powering the phone is a 4,000 mAh battery that keeps it going for almost a day. Only those users who extensively stream multimedia over internet, play graphic-intensive games, and use social media a lot might need to charge the phone in between. Otherwise, the phone’s battery is good enough to stay for one full day. The phone supports the 27W SonicCharge technology, which charges the phone from zero to 100 per cent in around an hour. However, the SonicCharge is sold as a separate accessory, and the phone comes bundled with an 18W fast charger, which takes half an hour more to charge the battery to full.
