ChargeLimit

This is a procedure to set up a Wi-Fi smart plug along with the IFTTT and AccuBattery apps for Android to limit charging to a selectable percentage when charging your phone overnight. Additionally, a trigger can be set up to turn on charging once battery level drops below 15% to ensure the phone does not run out of charge.

Prerequisites

• Wi-Fi enabled Smart Plug compatible with IFTTT (I used a Kasa smart plug, which is available in a 2-pack for $14.99 on Amazon).
• IFTTT application installed on Android phone to be charged
• AccuBattery application installed on Android phone to be charged

Setup

• Launch AccuBattery and go through initial setup (letting it determine charging current direction), and select your charge limit. For my Pixel 4A, using a fast charger, I picked 60% which charges the battery to ~4.1V.
• Install your Smart Plug app and set it up on your network.
• Launch IFTTT app and set up the following:
