This product claims to have up to 16 hours of battery life and that's a flat out lie. It took over 10 hours to "fully charge" and was completely dead after barely 3 hours of use at half volume. The battery life is absolutely trash on this thing and I'd recommend buying a different brand for the money. Jbl used to be good, don't know what happened, probably outsourced their parts and labor to countries with cheap child labor and it shows.

Thank you for bringing this to our attention. The published up‑to playtime of our JBL Flip 7 reflects the maximum battery life at low volume. Higher volume and boosted bass will reduce playtime—similar to how a phone battery drains faster with a brighter screen. In many cases, the battery is functioning normally but depletes faster under louder listening conditions. To check battery health, charge the unit to 100% and play music at a very low volume with no bass boost. If the playtime is close to the published specification, the battery is performing properly.
