Hardware Battery Charge Limiter
Stop replacing batteries every 2 years. Set an 80% limit overnight, extend battery lifespan 2β4Γ, and save hundreds in replacement costs.
This is a proven fact. Leaving your phone plugged in overnight keeps the battery at maximum voltage for hours, causing irreversible chemical degradation.
A typical smartphone needs battery replacement after just 2-3 years. That's $150+ in repairs, or worse β buying a new device.

Watch Reviews βEvery phone kept in use longer is one less in a landfill. Chargie helps you make a real environmental impact.
Most people replace their phones not because they're broken, but because the battery no longer holds a charge. This creates a massive cycle of e-wasteβover 50 million tons annually.
Each smartphone contains precious metals mined from the earth: lithium, cobalt, gold, copper, and rare earth elements. Mining these materials causes deforestation, water pollution, and carbon emissions.
πΏ By extending your battery's life with Chargie, you're not just saving moneyβyou're actively reducing demand for new mining and keeping toxic e-waste out of landfills.
It's a small change in how you charge that creates a meaningful environmental impact. And it pays for itself many times over.
See how Chargie protects batteries in real-world scenarios β from overnight charging to professional applications.
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.
Studies found that ~45% of parents and 30% of children sleep with devices turned on and plugged in overnight. Battery fires are a real risk.
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.
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.
Professional drivers use devices as navigation systems all day β staying charged for thousands of hours monthly in direct sunlight. Hot + fully charged = dangerous.
Chargie's hardware limiter protects regular batteries without apps. By measuring power and detecting the charging threshold, it cuts off power automatically.

"Nokia Labs in Romania chose Chargie to protect their development phones during intensive 24/7 testing cycles. When you're testing phones around the clock, battery health is critical. Chargie was the only solution that delivered both smart charging limits AND maintained USB data connectivity."
If it's good enough for Nokia's R&D lab, it's good enough for your devices.

"We have kiosk booking devices, which are basically mobile phones, that we deploy to customers. These phones are on 24/7. Some phones would fail after a number of months with battery issues, due to being constantly on charge. We now use Chargies on all devices to better manage the charging cycle. This has substantially extended the life of our booking devices."

Great question! Here's why Chargie offers superior battery protection compared to stock solutions.
Built-in solutions are reactive β they try to manage charging after it's already happening inside your phone. Chargie is proactive β it controls power at the source, stopping electrons from even reaching your device when they shouldn't. This physical control is more reliable and works universally across all devices and operating systems.

Keep your battery healthy at night, fully charged in the morning.
Chargie's "Top Up Scheduler" has the unique ability to keep your phone at a safe state of charge during the night (50 to 70% is best) and only top it up to a value of your choice in the morning, just before you wake up.
Avoid prolonged high states of charge that degrade battery capacity over time
Keep your phone at 50-70% overnight, reducing fire risk and battery stress
Wake up to a fully charged phone without the overnight battery damage
Set your own wake-up time and desired charge level for maximum flexibility
Better than stock solutions: This is much better than current stock solutions implemented by some manufacturers. You get the best of both worldsβbattery protection at night and full capacity during the day.
The scheduler works by maintaining your phone at a safe, low charge level overnight (typically 50-70%), then automatically topping it up to your desired level (80%, 90%, 100%) just before your scheduled wake-up time. This approach dramatically extends battery lifespan while ensuring your device is ready for the day ahead.
Stop charging when it matters mostβin hot conditions.
Sometimes, it's better to just stop charging in high temperature situations, like when using your phone as a navigation device on your car dash in hot summer days.
In such cases, heat degrades the battery's internal structure more than anything. If exposed to heat for a long time, the battery eventually swells and can ruin your phone or explode.
All phones have some sort of overtemperature protection, but the factory threshold is often set too high to properly protect a battery from premature aging (typically 50Β°C / 122Β°F).
Lithium-ion batteries are very sensitive to heat. A battery dwelling above 30Β°C (86Β°F) is considered elevated temperature. Exposing the battery to high temperature while in a full state-of-charge can be more stressful than cycling.
Chargie allows you to charge your phone at much lower temperatures, so that your battery health doesn't degrade as much during long sunny drives or hot summer nights. Automatically.
