Step by step

1. 

   Open Battery

   Open Settings and tap Battery.

   Done

2. 

   Tap Battery health

   Scroll past Battery usage by app to Battery settings.

   Done

3. 

   Read Maximum capacity

   OPPO says it is an estimate compared to when the battery was new; a lower percentage means less use between charges.

   Done

4. 

   Turn on Smart charging (optional)

   It learns your habits and may hold the battery at 80% until shortly before you need it. It was off in ours.

   Done

If you do not see this option

• No Battery health row? Use OPPO's battery check instead. OPPO gives it by version in its battery troubleshooting: ColorOS 14 and 15, Phone Manager, the three dots, Diagnostics, Battery & Charging, Run diagnostics; ColorOS 12 and 13, Phone Manager, Tools, Diagnostics; ColorOS 11, Phone Manager, Diagnostics, Continue, Battery & Charger.

• Not on the first screen of Battery? On our ColorOS 16.0.5 it is below Battery usage, under Battery settings, so scroll down. You can also search Settings for battery health.

  

• Want it to stop at 80-90%? Custom charging limit is a switch on the same page; the page recommends 80%-90% to slow battery ageing. Turned on, ours showed a Battery 90% slider, and a notification later said charging was complete at the set limit of 90%. We turned it back off.

  

If this does not work

• Stops at 100% and drops a bit? That is Resume charging at 95%, which was on on ours: charging stops when full and starts again below 95%.
• Won't charge fully, or warns about temperature? OPPO says the phone stops charging at extreme temperatures and shows Temperature is too low/high, the battery cannot be charged. Its ideal range is 16 to 25 °C. Source: About OPPO Smartphone Batteries
• Capacity low and the phone dies early? OPPO recommends having the battery replaced only at an authorised OPPO service centre, with your proof of purchase and a backup first. Source: When Should You Replace Your OPPO Phone Battery
