The battery life on the JBL speaker Flip 5 we discuss in terms of the following. Either how long the unit plays after a full charge before going dead again. Or, how long the battery lasts before needing replacement.
JBL Speaker Flip 5 Battery Life Per Charge
How long should the battery last? The built in lithium ion battery lasts up to twelve (12) hours per full charge. Note that this time varies depending on how loud you play the speaker, and the type of audio.
JBL Speaker Flip 5 Battery Life: Before Replacement
How Many Full Charges Should the Battery Take ?
The JBL Flip 5 battery should provide at least 500 charge-discharge cycles before it loses much ability to hold power.
Signs of a Bad Battery
The Flip 5 Takes Too Long to Charge
Using the USB-C cable that comes with the 5, or better, the battery should fully charge in under three hours. Now it make take longer if your charger adapter provides less than fifteen watts (5 volts at 3 amps). But now assume that your cable and charger are hefty enough. Yet the battery takes longer than three hours to fully charge. In that case, it may be going bad.
The JBL Speaker Flip 5 Doesn’t Play as Long as it Should
The Flip 5 may not play as long as it did before running down from a full charge. This is another sign of a battery nearing end of life.
It Distorts or Shuts Off at Higher Volumes
When you raise the volume, particularly on music that has lots of bass, you may hear crackling or other distortion. Or, the speaker may cut out or power down when a deep bass drum thump occurs in the music. Perhaps the battery can no longer provide enough current to play these sounds. So again, this may indicate a need to replace the battery.
The Battery Gauge Gives Wrong Readings
The gauge may show that the speaker has full, or nearly full charge. But yet, it goes dead within minutes of reading the indicator. This is a common symptom when lithium ion battery life is fading.
JBL Speaker Flip 5 Battery Life: How to Get the Most of It
Exercise the battery ! That is, charge it all the way, and discharge it all the way. The power management system seems robust. It well protects the battery from over charging or completely draining.
However, avoid leaving the speaker on the charger once the battery gauge shows full. Also, when the battery does run dead, do not leave it dead for very long. We recommend recharging your speaker as soon as possible, as these batteries hate being dead. A dead battery for too long often results in a ruined battery.
Conclusion
Replacing the battery in the JBL Flip 5 usually fixes the above mentioned issues. However, only replace with a battery of similar type — preferably the same make and part number as the original.
Finally, you can often avoid ever having to replace the battery due to shortened battery life. How? By keeping the battery charged. But exercise it as well. This provides the most deep charge-discharge cycles from it in our experience.
