Your devices lose 5-20% battery health every year from prolonged high-voltage charging

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 — buying a new device.

Battery health degradation over time - 95% year 1, 80% year 2, 65% year 3

"But doesn't my phone have this already?"

Great question! Here's why Chargie offers superior battery protection compared to stock solutions.

📱 Built-in Solutions

What Your Phone Does

  • 80% limit only — Most phones only offer 80%, which isn't optimal for all use cases
  • No scheduling — Can't top up to any charge level (not just 100%) just before you wake up
  • Software-dependent — Only works when phone OS is running
  • No temperature awareness — Most don't stop charging in high heat situations
  • Device-specific — Can't transfer to a new phone
  • Limited customization — Take it or leave it
⚡ Chargie

What Chargie Does Better

  • Any limit 20-100% — Choose the exact percentage for your needs
  • Smart scheduler — Keep at 60% overnight, then top up to any level you choose (e.g. 80% or 100%) before waking
  • Hardware limiter — Works even with phone off or crashed
  • Temperature protection — Set your own threshold (as low as 30°C)
  • Works on any device — Transfer between phones, use on tablets, laptops
  • Full control — Hysteresis, power modes, multi-device profiles
💡

The Key Difference

Built-in solutions are reactive — they try to manage charging after it's already happening inside your phone. Chargie is proactive — 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.

🚗 Proven EV Battery Technology

Electric cars are projected to last 300,000–500,000 miles in part because manufacturers recommend charging to only 80% daily. The same science protects your phone and laptop.

Chargie automatically stops charging at your chosen level — preventing the heat and voltage stress that kills batteries. It's the easiest way to double or even quadruple your device's battery lifespan.

Electric vehicle charging technology
"A voltage above 4.10V/cell at elevated temperature causes degradation, a demise that can be more harmful than cycling a battery."
Prof. Jeff Dahn, Dalhousie University
Tesla's battery research partner • Battery University
"Every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life."
Isidor Buchmann, Founder & CEO, Cadex Electronics
Creator of Battery University • BU-808

Charging on Autopilot

Simply plug in Chargie between your charger and device. It automatically stops charging at your set limit, extending battery life by 4x.

Your Impact

The Hidden Cost of Battery Degradation

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-waste.

"Humanity produces 62 million tonnes of electronic waste every year — rising by 2.6 million tonnes annually — yet only 22.3% is properly recycled."
Global E-waste Monitor 2024

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.

🌿 By extending your battery's life with Chargie, you're not just saving money—you'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.
