The battery level meter gauge showing a full charge on the JBL Charge 5 Speaker.
The JBL Charge 5 battery life at full Volume we discuss in terms of the following. How long the 5 plays at loudest volume. So we assume a full charge here.
How long should the battery last? The built in lithium ion battery lasts up to twenty (20) hours per full charge. But at full volume, we often get only about eight (8) hours per charge. Note that this time varies depending on how loud you play the 5. The ambient temperature around the 5, and the type of audio you’re listening to also affects this. Charging external devices like phones and tablets with this speaker also shortens its Battery Life Full Volume.
The battery should provide at least 500 charge-discharge cycles before its performance begins to degrade. This is even when you typically play it at full volume. But however loud you play it, avoid storing the unit in very hot or cold places. This gives you the most recharge cycles. Also, do not leave the 5 dead. And do not leave the charger connected for long once charging is complete. Doing any of this will drastically shorten battery live, whether you play it at full volume or not.
Using a large enough USB-C cable, the battery should fully charge in under four (4) hours. Now it may take longer if your charger provides less than fifteen watts (5 volts at 3 amps). However if these are hefty enough, yet recharging takes too much longer, then the battery failure may be to blame.
You may also notice that the 5 doesn’t play as long as it did when new. This is another sign of a battery that is nearing the end of life.
When you raise the volume, particularly on music that has lots of bass, you may hear crackling or other distortion. Or, it may cut out or power down when a deep bass drum thump occurs in the music. This could mean that the battery, even at full charge, can no longer provide enough current for correct operation. Again, this may mean that replacing the battery is necessary.
The gauge may show that the 5 has full, or nearly full charge. But yet, it goes dead within minutes of reading the indicator. This is a common symptom when useable Battery Life Full Volume is fading.
Exercise the battery ! That is, charge it all the way, and discharge it all the way. The power management system in the 5 seems robust. It well protects the battery from over charging or complete draining.
However, we suggest that you do not leave the 5 on the charger once full. Also, when the battery does run low, do not leave it in this deadened state for long. Instead, recharge your speaker as soon as possible, as these batteries hate being dead. A long-dead battery often results in a ruined battery.
Replacing the battery in the JBL Charge 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 Full Volume. How? Keep some charge in your speaker. Plus, exercise it as well. This provides the most deep charge-discharge cycles from it in our years of experience with these devices.
