Please open the Settings app on your vivo smartphone, navigate to Battery, then select Battery health and charging option, where you can check the Maximum battery capacity of your mobile phone.
If the displayed maximum battery capacity drops below 80%, your daily battery endurance and overall usage experience of the vivo smartphone may be affected. Under this circumstance, we suggest you visit an official vivo customer service center for comprehensive professional battery inspection and testing.
Note: Your maximum battery capacity reading will be refreshed to 100% after you complete official battery replacement service at an authorized vivo service center. If you cannot find this battery health menu on your mobile device, please contact customer support to confirm whether your vivo smartphone supports this function.
