How long does the ROLI Piano M or LUMI Keys battery last?
Battery life on ROLI Piano M and LUMI Keys depends on the lights and Bluetooth. How to charge it, and how to play for hours without running out.
What uses the battery
The light-up keys and Bluetooth use the most power. Bright lights and wireless play empty the battery faster than playing over a cable with the lights dimmed.
How to charge it
Use the USB-C port. A wall charger is usually faster than a computer port. A completely empty battery can take a while before the keyboard turns on again, so leave it plugged in for a bit.
Play without running out
When you play over a USB-C cable connected to your computer, the cable also powers the keyboard. For long practice sessions, USB is the easiest way to never run out.
Frequently asked questions
Can I play while my LUMI Keys is charging?
Yes. Connect it to your computer with a USB-C data cable and you can play in DOLI PIANO while it charges.
My LUMI Keys won't turn on after charging. What now?
Leave it on a wall charger for at least an hour, then hold the power button for a few seconds. If nothing happens with another cable and charger, contact ROLI support.
