Amply is experimental and pre-launch. Direct control is verified on a limited set of devices — device reports and feedback are welcome!

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.

Setup & access

Install Amply, then enable control through one access path:

adb shell pm grant eu.darken.amply android.permission.WRITE_SECURE_SETTINGS

Alternatively, start Shizuku, grant Amply access, and optionally use Amply’s setup card to grant durable WSS. WSS-only control can write Pixel’s hidden values but Android blocks direct third-party reads, so Amply also watches Android’s public charging-hardware state; Shizuku provides exact configured-setting readback while it is running. On tested Pixels, Google’s policy worker takes roughly 10–15 seconds to propagate a setting change to the charging HAL.
