Sorry, OPPO phones don't support checking the battery consumption level for the time being. You can take your purchase certificate to the OPPO offline service center to test the setting method of the percentage of electricity displayed in the status bar of the mobile phone: 1, ColorOS 12. 1 and above. Go to settings > notifications and status bar > status bar > battery percentage, and then select the battery percentage display style.
2. color 1 1.0- 12.0 and above, go to "settings > battery > more", and open "status bar shows power percentage".
3. version 7.0-7.2 of coloros, go to "settings > battery > turn on" show percentage of power in status bar ".
4. in coloros version 3.0-7.2, go to settings > notifications and status bar > turn on power percentage.
Note: This answer is applicable to all models of OPPO.
