⏰

Target Charging – Wake Up with the Perfect Battery Level

Plan to reach a defined battery level by a specific time.

Example: You want your phone to have around 80% battery at 7:00 AM
DefinedCharge monitors the charging process, takes care of everything, and recharges overnight via the smart plug if the battery level drops below your defined threshold

🎯

Jog Mode – Keep Your Battery in the Ideal Range

Keeps your battery within a user-defined range using a smart plug
Charging starts when the level falls below the minimum value and stops when the maximum value is reached
Charging occurs only when necessary, even if the phone remains connected by cable or on the wireless charger

🌡️

Temperature Monitoring – Safe Charging

Monitors the temperature during charging
If the temperature rises above a defined value, an audible alert sounds and charging can be stopped via the smart plug

Sustainable and Smart – Save Energy with Your Smart Home

💡

Standby Killer

Activates chargers through the smart plug only when charging is actually needed. This avoids unnecessary power usage during standby.

🌱

Environmental Protection

Reduce your electricity consumption while increasing your battery's lifespan – helping preserve valuable resources.

♻️

Resource Conservation

Make an active contribution to sustainability by preventing unnecessary overcharging and heat buildup.

Note: The smart plug itself uses a small amount of energy — but for many models, it's significantly less than what a charger left permanently plugged in can draw.
