About 20% capacity lost in one year
Thatβs the estimate for a lithium-ion battery stored at 100% charge and 25Β°C (77Β°F). Actual loss varies with the battery, temperature and time spent full. Source: Battery University, Table 3.

Chargie sits in the charging path and physically switches the power. The app puts you in control.
Stop at your limit
The app reads your battery level and tells Chargie over Bluetooth when to stop and restart charging.

02The problem
Hours at 100%
quietly wear your battery down.
Keeping your phone or laptop fully charged overnight or through a long workday can speed up battery wear. Capacity fades little by little, even while the screen still says 100%.

03How Chargie helps
You choose the limit.
Chargie switches the power.
Chargie is a USB charging limiter: the app reads your battery level, then tells the hardware over Bluetooth when to stop and restart charging.
Controls vary by platform and version.
Set your limit
Choose 80%, for example.
Charging pauses
Chargie interrupts power at 80%.
It restarts when needed
Here, charging resumes at 76%.
