I have been having issues with a Xiaomi Redmi7 running MIUI based on Android 9. I have Sophos Security Guard installed because I use the App Protection feature. However, the MIUI battery saver keeps on turning it off as part of its battery optimization. I have tried turning off battery optimization at the app settings, but MIUI battery saver just keeps switching back to the On state by itself for some reason (this is particularly noticeable right after rebooting the phone).
One thing I have noticed though is that if an app is set as a device administrator and I turn off the battery saver setting for that app, it stays off permanently. I have Sophos Mobile Security set as a device administrator and the MIUI battery saver leaves it alone. Unfortunately, there is no option to set Sophos Security Guard as a device administrator, so I can't do the same to stop battery optimization from interfering with App Protection.
Does anyone here use a Xiaomi of the same model, or at least running the same MIUI? Please help if you know a workaround on this issue. Or if Sophos could update the Security Guard app to allow setting it as a device administrator, that would greatly help Xiaomi users like me.
PS: I check my online accounts (like this one) at least once a week. Please feel free to drop a message if you have a solution or if you need more information from me. I'll respond as soon as I see your message.
Thanks in advance.
Hi Mark Lopez
Could you please check by installing Sophos Mobile security on the device and check the following article for disabling battery Optimization. Let me know if it helps.

Thank you for responding. The issue is not with the Mobile Security app but the Security Guard app. I have already tried turning off battery optimization at a per-app level for Security Guard, but Xiaomi's MIUI keeps on turning it back on, which in turn affects App Protection in Mobile Security.
Kindly take note that I have not found a setting within MIUI to turn off battery optimization completely, so I am relying on the per-app level setting to stop it from interfering with apps which need to stay on.

Is there anyone out there who could help?
If battery optimization for Security Guard application gets enabled by MIUI after some time, I'll advise you to open support through this link as this needs more logs and also need to check the many more things from OS perspective.

Thank you for responding. I am using your Sophos Mobile Security as a free user (no active subscriptions with Sophos Central nor with Sophos Mobile). Should I choose to file a support case, will my issue be entertained in this case?
I guess no one could help on this one then.
