Editor's Overview

Plus Plus Battery is a battery application developed by F-Droid Open Source, packaged as a single Android APK of version 2.3 weighing in at 3.08 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 3.08 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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
- Reads generic linux power supply files under /sys/class/power_supply/battery for universal devices
• Customizable paths/titles/units for anything you want to read with root access

• Experimental
- Gets battery data from logcat (root required)
• Currently only some OPlus, Moto & Xiaomi devices are supported (depends on models and systems)
───────────────────
■ INSTALLATION
───────────────────
1. Make sure your handset runs a recent OxygenOS / ColorOS build or another
up-to-date Android ROM.
2. Install the APK (or via F-Droid once this package is published).
3. Launch and grant the requested permissions.
4. (Optional) Grant root to unlock advanced metrics.
5. (Optional) To make the monitor service work as intended, disable battery optimisation for
PlusPlusBattery and, on ColorOS 15, enable “Auto-launch”.
6. (Optional) For non-Oppo/OnePlus/Realme devices, you may want to disable the option 'Show OPlus exclusive entries' to hide those useless data under root mode.

Frequently Asked Questions

Is Plus Plus Battery free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).
