Witty | Type A
Witty is a plug-in that protects the battery of your mobile devices.
By automatically disconnecting your device from the power grid once it reaches 100%, Witty prevents your battery from any performance drops throughout time, as well as the harmful end-of-charge voltage.
Witty is not designed only for smartphones, but for any USB recharged devices up to 65W (drones, tablets, Bluetooth headphones). It is compatible with Android, iOS and Windows.

Why does battery efficiency decrease a few months after purchase?
Once the charge is completed, the device is directly charged through its cable. However, this means that the battery is kept at its end-of-charge voltage (4.35V), which causes an irreversible deterioration of its lithium during the night.
By using Witty instead, your device is isolated and disconnected from the power grid once the charge has reached 100%. This allows a reduction of the battery voltage to non-harmful values.
Preventing the battery lithium from being exposed to harmful voltage values for a long period of time is crucial to protect your battery health and, consequently, double its lifetime.

Witty A VS mobile devices software
The Optimized Battery Charging won’t engage when your usage habits are more variable, such as when you travel. This results in a battery stucked at 80% or mainteined at 100% charge (end-of-charge voltage). Witty A always disconnects the device from the power supply once it has reached 100% charge, avoiding the end-of-charge voltage.

FAQ's
Does my smartphone stop charging when it reaches 100%?
All devices with lithium-ion batteries cut off the current flow once they reach 100% charge but maintain the battery at its end-of-charge voltage (at 100%) until the cable is disconnected.
Keeping the battery at high voltages causes rapid wear of its electrodes, which results in a shorter daily duration of the battery charge.
As if, after inflating a balloon, you want to keep
it under tension to avoid it deflates.
My smartphone has optimized battery charging
Apple’s optimized battery charging learns your usage routines and only works if these are regularly met. If, for example, your alarm changes, the optimized charging won’t work.
Which devices are compatible with Witty?
Witty is compatible with any smartphones on the market and most of the USB rechargeable electronic devices. Witty is not compatible with Laptops, Notebooks and Ultrabooks.
How can i use Witty if I have a USB type C?
You can use Witty if you have a USB type C thanks to small adapters that convert USB type C to the classic USB type A, or by charging the device with a 5V charger. USB type C adapters are available on our online store.
Does Witty work with wireless charging pads?
Yes, Witty can read the energy input required by the battery even when using wireless charging, as long as only one device is charged at a time.
However, some wireless chargers are equipped with a LED indicating they are actively working, which consumes a lot of power. In these cases, Witty may not be able to disconnect the device from the power supply and you will need to charge your device using the supplied cable.
What is the difference between Witty A and Witty C?
Witty A works with USB type A chargers (big usb). Witty C, equipped with adapters, is designed for all devices with USB type C chargers.
