How to tell if UE Roll is charging? This waterproof speaker with built in bungee loop has a two-color LED lamp on its back top, in the Power button, as shown in the pictures next. This light not only gives speaker power OFF ON status. But it also tells battery level (whether it’s near dead or not) as well as charging status. To see if the Roll is charging, check this light. We show how to read it next.
How to Tell if UE Roll is Charging
Connect your Roll to USB Power
Of course, you know that this speaker is NOT charging with no charging cable plugged in.
Check the Power Button LED on Speaker Back
Whether this Roll is OFF or ON, you can tell if it is charging. If it is indeed connected to a charger, the Power lamp quickly pulses in a brightening and dimming pattern.
When not charging, this light glows steady red when the battery nearly out of power. It flashes red when the battery is critically low. It glows solid white otherwise when the speaker is powered ON. The lamp is OFF when the speaker is OFF.
Should the UE Roll power lamp glow steady red with a charger plugged into it, then the speaker is NOT charging. You never see red when the speaker IS charging. So you might check that your USB cable, adapter charger, and power source are working. Try a new USB adapter or another charge cord. This light should blink white to know for sure that the UE Roll is charging.
How to Tell if UE Roll is Charging Fully
As speaker charging nears the end, the power LED keeps flashing white. You can hear how full the battery is by turning the speaker on, and then quickly pressing and releasing the Volume UP and Volume DOWN buttons together.
The power lamp on the other hand, just shows that charging is indeed going on. See the white glowing lamp in the first picture above, pointed at by the green arrow.
Now, the Roll does not warm much as it charges. But you can feel the charger to check that charging is indeed in progress. If the charger heats a little, then it is putting out some current. Some current draw usually means that charging is occuring. So moderate charger heating is a good way to tell if the charging is happening.
When the Power LED Goes Off or Turns Solid White, Then UE Roll Charging is Done
The battery charge cycle is over when the power LED changes from pulsating white to either OFF or solid white, as shown in the next two pictures.
Even with the charger cord still plugged in, and when the Roll is powered down, this lamp stops glowing with a full battery, as shown in the last picture. The UE Roll no longer recharges when the battery reaches full charge condition.
Finally, Unplug the UE Roll and Power it On
If the power LED glows solid white as pictured above, this could mean that it did indeed charge, particularly if the speaker was dead or near dead before you plugged it in. But with the USB cable unplugged, we cannot know just by reading the power LED, just how much this speaker really recharged, only that it did charge some. It likely did charge to full though, as long as we waited until the light stopped blinking before unplugging the charger. To know for sure, as mentioned above, we can power up the speaker and press both volume controls, and hear the speaker announce the battery charge percentage.
Happy listening to your Roll UE speaker!
