Practical Use Cases
See how Chargie protects batteries in real-world scenarios β from overnight charging to professional applications.
Phone Lifespan Extension
Chargie has been designed to protect batteries. Just juice your phone through it and in a few months you will see the difference β your battery life will be like when it was new.
- Higher resale value with certified battery health
- Give perfectly working phones to someone in need
- Same Chargie works with your next phone too
Safe Overnight Charging
Studies found that ~45% of parents and 30% of children keep devices within reach while sleeping (National Sleep Foundation, 2014). Battery fires are a real risk.
- Keep devices at 50% overnight β near-zero fire risk
- Top up to full just before you wake up
- Peace of mind for the whole family
Always-Charging Demo Phones
Demo phones in shops stay connected to mains 24/7 β that's what destroys their batteries. After a few months they start swelling or even catch fire.
- Partial charging = near-zero battery damage
- Eliminates fire risk in retail environments
- Higher resale value for demo units
Remote Surveillance Systems
Phones and tablets used as surveillance equipment often run on solar power, with batteries staying at 100% all the time β causing swelling and fire risk.
- Devices stay charged at 50% β zero fire risk
- Perfect for forest protection, security systems
- Solar-powered installations stay reliable
Taxi & Professional Navigation
Professional drivers use devices as navigation systems all day β staying charged for thousands of hours monthly in direct sunlight. Hot + fully charged = dangerous.
- Limit charge to 50% β greatly reduced battery damage
- Eliminates fire risk on hot summer days
- CarPlay without constant charging β keep data, limit power
Basic Battery Protection
Chargie's hardware limiter protects regular batteries without apps. By measuring power and detecting the charging threshold, it cuts off power automatically.
- Works with cameras, drones, watches, power banks
- No app required β pure hardware protection
- Prevents overcharging fires in any device

The benefit of a charge limiter depends on how long the device would otherwise sit at full charge. These are the situations where that time is longest.
Overnight charging at home
Seven hours a night at 100% is the most common source of battery wear for ordinary users. An 80% limit with the scheduler removes almost all of it; users typically report their phone still above 90% design capacity after two years.
Demo phones and kiosks
Connected 24/7 and often warm, these devices age two to three times faster than a personal phone. A 60β70% limit is the difference between replacing them every two years and keeping them for five.
Surveillance and remote systems
A phone used as a camera or sensor is docked permanently and unattended. Beyond capacity loss, a hot cell held at full voltage is the classic precondition for swelling. Limiting charge is a safety measure as much as a longevity one.
Taxi and delivery navigation
Navigation keeps the processor busy and the screen on while the phone charges in a hot cabin. Combining the limit with overtemperature protection keeps the battery under 40 Β°C for most of the shift.
