Amply

Amply is an Android controller for OEM battery charge-protection modes. Its primary action temporarily allows one full charge, then restores your protective charge limit automatically — at 100%, on unplug, or at a safety timeout.

Features include:

One-tap "charge to 100% once", then automatic restore of your protective limit A dashboard that reports charge state honestly — verified, last-requested, or unknown Optional "reconnect to charge to 100%" gesture at the active hardware limit Quick Settings tile and a home-screen widget for protect / full-charge actions A persisted temporary-session monitor that survives reboots Diagnostics workflow (Shizuku) for before/after setting discovery, with redacted reports Works without ADB/Shizuku too — a charge alarm to remind you to unplug at a chosen level, a live battery-info card, and an OEM battery-protection guide on unsupported devices Branded light/dark themes, optional Material You, and contrast choices Works via WRITE_SECURE_SETTINGS or Shizuku No ads, no tracking, open-source (foss and gplay flavors) Currently supported for direct control:

Pixel 6a and newer, Android 15+ (Google charging optimization) Samsung One UI 8 (multi-mode battery protection) Samsung One UI 4 / 5 (legacy battery-protection toggle) Xiaomi / Redmi / POCO on HyperOS 2 (charging protection) OnePlus / Oppo / Realme on ColorOS 15 (charging protection; requires Shizuku) Other devices — other Pixels, Samsung One UI 6/7 and 9+, non-HyperOS-2 Xiaomi, and non-ColorOS-15 OnePlus/Oppo/Realme — are diagnostics-only for now.
