Plus Plus Battery

PlusPlus Battery gives you everything you ever wanted to know about your phone’s
battery — from simple level and power readings to deep-dive metrics.
It is designed and tested on modern OnePlus/Oppo/Realme devices,
but also works on most recent AOSP-based ROMs.

■ KEY FEATURES
──────────────────────────
• Real-time dashboard
– Level, voltage, current, charge / discharge power
– Works with and without root

• Battery-health estimation
– Without root access: Calculates Full-Charge-Capacity when the
battery is exactly 100 % and reaches 0 mA current

• Cycle-count history
– Saves today’s cycle count to a local Room database each time you open the
app, and shows the trend in a timeline view

• Persistent monitor notification
– Ongoing notification-area battery monitor with customizable metrics

• Optional root mode
– Reads additional sysfs nodes under /sys/class/oplus_chg/battery and some other directories, including
• Current remaining capacity (battery_rm)
• FCC (battery_fcc) and SOH (battery_soh)
• Raw, uncompensated FCC/SOH values (especially for silicon batteries)
• Under-voltage shut-down threshold (vbat_uv)
• Battery serial number, manufacture date, Qmax, and more
