The battery takes approximately 120 minutes to fully charge. Sudio Elva also supports quick charge, 15 minutes of charging gives 1 hour of playtime.
The Elva can be charged with a USB-A to C cable included in the packaging.
You can also charge your Sudio Elva by simply pulling off the part of the control panel which has 3 buttons on, and connecting it directly to your PC or laptop.
Battery level indicators
When the battery level is low, the LED light indicator on the back of the controller will glow red.
Battery life status will be indicated on your smartphone for iOS and most Android devices. Since phone manufacturers have various Android devices that work differently, you can also download various battery apps on the Google Play Store.
