JBL Flip 4 Charge Time: How Long it Plays Per Single Charge

On a full charge, the JBL Flip 4 speaker can play for up to twelve (12) hours from a single charge, due to its 3,000 MaH, 3.7 volt lithium ion polymer battery.  But when you play it extra loudly, especially with lots of bass, you will see significantly shorter charge holding time.  We’ve seen this speaker run dead in around nine hours when run at party level volumes. So to get the most charge time from it, power conservation is key.  Only play it as loudly as you need to.

The Charge Time Shortens Over Time

If you own this speaker over a several year period, you may notice that the time it plays from a single charge decreases as the speaker ages.  This is normal for devices like this one, that rely on lithium ion polymer batters.  But by exercising the battery, you can slow this decline.  To exercise the JBL Flip 4, run the battery dead and charge it again every three to six months when not in use.  Also, we suggest that you not leave the speaker plugged into a charger once it is fully charged.  Once the charging lamps completely go out, disconnect the speaker right away to avoid overcharging and battery damage.
