Xiaomi Redmi Note 4 is one of those devices that have contributed to the success of Xiaomi massively, so much so that the company has presented two versions with different CPUs, one based on the Qualcomm SoC and the other on that of MediaTek, ie MT6797, Better known as Helio X20, decacore with 64 tri-cluster bit architecture so divided: Dual-core 2.1 GHz Cortex-A72 + Quad-core 2.0 GHz Cortex-A53 + Quad-core 1.4 GHz Cortex-A53.
Just this variant, however, seems lately to be afflicted by an annoying bug that sees a excessive overheating and a battery drain reckless without any apparent cause. But fortunately there seems to be one available simple solution and painless that is proposed by the various forums on the network concerning the Xiaomi Redmi Note 4 of which we invite you to read the our complete review.
The solution consists of uninstall automatic updates for the Google Duo application. To do this we enter the Settings → Installed Apps and search for Google Duo. Clicking on it will open a screen where in the middle of the center will appear the item Uninstall updates. Once you have done this you will have to go inside the Play Store, tap on the three lines on the top left and choose the Settings item where you will disable the Automatic app update option by choosing the option Do not automatically update the app.
If this operation still does not solve your problem, the solution is to remove the Google Duo app which theoretically you could not do as a system app, and then you will have to resort to a third-party application, free and that does not require root permissions. Personally we have not tested this solution but the feedback in the forum seems to be positive, so you just have to try to download the application Redmi System Manager by clicking on the button below.
