Sony SRS-XB23 Not Charging, How to Fix

Most Sony Bluetooth speakers, including the XB23 mini model, offer truly portable operation via their lithium ion batteries inside. And when said battery dies, you can recharge the speaker with an AC or car adapter. Sometimes though, you may notice that the Sony SRS-XB23 is not charging fully, or at all, even when you connect the adapter to power, and then to the speaker.  To solve that, we’re here to help.

How to Tell that the Sony SRS XB23 is Not Charging

Read the CHG Lamp

Among the ways you can tell that the XB 23 is not charging, is by reading the orange CHG lamp on the side of the speaker.  Now this light is normally dark. But starts flashing orange during play, when the battery is going low.

But there’s a problem if this flashing keeps up, even when you attach the charger.  Why?  Because the lamp should change at this point though, to solid orange.  When the light stops blinking, and assumes a steady orange glow, this means that the speaker is getting some power from the adapter. But if the orange pulsing continues, then correct recharging is likely not happening.

Furthermore, the status light shows battery charging status while recharging.  I.e. As long as charging continues, this lamp also continues glowing solid orange.  And this light goes out when charging ends.  But if that CHG lamp keeps glowing after several hours of recharging, then chances are, charging is not going well.

Feel The Heat

You can also feel the power supply’s side panel ten or fifteen minutes after connecting it to the 23.  At that time, it should feel warm. But if you detect no warmth, then again, the Sony SRS-XB23 is likely not charging.

Thus when you notice that the speaker is not recharging, even though it should be, you’ll want to determine what’s wrong and how to resolve this problem.  So in this post, we offer reasons why the Sony SRS XB23 speaker may not charge when you apply power.  Then we give possible fixes for this seen-often difficulty.





 Sony SRS-XB23 Not Charging, Reasons and Fixes

As we stated above, it’s normal that the CHARGE lamp pulses orange when the battery inside is about dead.  But again, the light should switch to a solid orange glow when you plug the speaker into the charger, and connect the charger to a power outlet.

Or, once recharging finishes, the CHARGE light goes dark. See this in the next picture.

If the light does not change to a continuous orange glow when you plug the charger into the speaker, then several things might cause this. We list these below thus.

1.The Power Outlet May Not Be Energized

The Problem

The AC or car adapter for the SRS XB23 may not output any energy because it is not receiving any to begin with. This can happen due to a defective circuit, tripped breaker, blown fuse, faulty wiring, power failure, and similar issues.

The Fix

Check that your outlet has power by plugging in a lamp or other device.  Then, reset circuit breakers if tripped, and if the outlet has a light switch that controls it, then be certain that that switch is in the ON position.  Or, simply try a different outlet.

2. The AC Adapter is Broken or Too Small

The Problem

The Sony SRS XB23 not charging can also happen because the adapter is outputting SOME but not ENOUGH amperage to fully charge the speaker, even though its getting the correct power input from the outlet.

Now as adapters age, their output energy can fall over time. So this power supply might not deliver the correct amount if it is very old.   So you may see the speaker’s CHARGE lamp turn solid orange, but never go dark.

Please note that this speaker needs 1,500 milliamps at 5 volts (7.5 watts) from the adapter to fully recharge in the specified time of 4 hours.  Yet charging will likely not go as fast as we hope if the charger does not deliver on these requirements.

The Fix

The solution is to replace the adapter, preferably one that has a USB-A plug and delivers 5 volts at 2 amp (10 watts) for consistently fastest charging. Many typical USB power supplies meet these requirements.





3. The Battery in the XB23 is Defective

The Problem

As lithium ion batteries age, they lose their ability to fully recharge, and the characteristics of the charging current they draw, changes as they get older.  Normally, as a battery recharges, it draws less and less current from the charger as it fills. But in the case of cells aging out, it may draw too many or too few amps, thus confusing the speaker’s charging circuits into behaving like no charging is occurring.  So the CHARGE lamp shows that charging is not happening correctly, either by never stopping its solid orange glow, or never turning on when you connect the charger in the first place.

The Fix

To resolve this, replace the battery. But realize that you can’t easily get the old one out of the 23. Indeed, changing the battery means that you must take the speaker apart, and this, be assured, is an intricate effort.

Also note that doing this likely breaks the moisture seal.  So the SRS-XB23 will no longer be safe to use, should you expose it to water afterwards.

Also, breaking this seal may alter the sound quality too. So get someone to replace the battery who knows how to choose the right part. They should also be able to restore the seal to as it was, as they reassemble the speaker.

A good battery should fit well inside the speaker and provide 2.7 watt-hours. But we suggest using only Sony certified batteries for this speaker.

4. The Speaker Might be Defective when the Sony SRS-XB23 Is Not Charging

The Problem

Even if you have the proper power supply, with a working battery in the speaker, the charge current that actually gets to the battery may be too low or too high.  This can happen when the battery management circuits inside the XB23 go amiss.  Note that these systems read the battery status, and switch off the charging current when they deem the battery full.

But when they go bonkers, the battery might see no power at all though the power supply itself is okay.  Thus, the speaker never charges.  Again, in this case, the Power lamp might never stop blinking, even with the charger connected. You may also see that the speaker doesn’t play as long before going dead, if at all, until you connect the charger. Or it might not play at all, even with the charger connected.

The Fix

The best answer here, is simply to get a new SRS XB23.  Why?  Because the electronics in this unit are quite small.  So unless you can replace the system board(s) yourself, or know someone who will do it, just buy another speaker to save a bunch of mental tension.
