Your Phone Battery Loses Capacity Every Time You Keep It Fully Charged.

What is Chargie?
Chargie is a USB device that stops phone battery degradation by automatically limiting charging at your desired level, while you sleep.
simple is magic
How Do I Use It?
1. Connect the Chargie USB stick between your charger and phone.
2. Install the app on your phone
3. Connect to your Chargie.
4. Go to sleep
The hardware and software will seamlessly communicate through Bluetooth and will cut charge at the level you select by dragging the slider in the app.
Effect: the lifespan of your battery will be hugely extended.
Even if you choose to charge to 100%, our hysteresis algorithm performs an optimized, stress-free charge for both long term battery life and daily phone usability.
No root access needed, because power gets cut off externally.
Chargie is the only system on the market that can do this.

Chargie – the phone charge limiter – Founder Edition – Blue
Researchers recently found out that charging your phone every night to 100% and keeping it this way for 8 hours stresses the battery and shortens its lifespan.
Chargie is the only Bluetooth switch that physically halts the charging process to your chosen value (the lower, the better), so you can actually use your phone for up to 10 years without noticeable battery drop.
The Science Behind
Charging a battery is more or less like compressing a spring – the more you push it every time to the maximum, the more deformation you introduce and the spring will cease to do its normal route after a while.
This table, courtesy of Battery University, shows the direct link between discharge cycles and the voltage that your phone takes the battery to when charging.
Battery expert company Cadex says that keeping a lithium ion battery fully charged and at high temperature is even worse than cycling it (going from zero to 100%).
The idea that limiting the charge to 90% (even 95%) can actually skyrocket the battery lifespan is one of the most exciting facts since the discovery of the lithium ion chemistry itself.
You can reduce the need for discarding the phone or performing expensive repairs to it and also avoid significant downtime. Having it perform as new for many years to come is also exciting for the next person using it.
And this is also a win for the planet, since you will be prolonging the lifetime of an object, which will not go to recycling or worse, to a landfill (which happens realistically in most situations). Extending the life of a battery is a very, very green thing to do.

Features and Tech
Chargie relies on Android, Bluetooth and a powerful 4.8A electronic switch to deliver current from the charger to the phone, and to stop it when the charge level has reached the desired value.
