Most Sony Bluetooth speakers, including the XB22, offer completely portable operation via their lithium ion batteries built in. 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 XB22 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.
Sony SRS XB22 Not Charging: How to Tell This
Read the Charge Status Lamp
Among the ways you can tell that the XB 22 is not charging, is by reading the orange battery status lamp on the back of the speaker, inside the port compartment. Now this light is normally dark, but starts flashing orange during play, when the battery is running low. The status lamp on the top of the XB22 also starts blinking when battery is low.
But there’s an issue 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 you apply charging power. When the light stops blinking, then the speaker is getting some power from the adapter. But if the orange flashing continues, then correct recharging is likely not happening.
Moreover, the CHARGE light shows battery charging status while recharging. I.e. As long as charging progresses, this lamp also continues glowing solid orange. And this light goes out when charging ends. But if that lamp keeps glowing after several hours of recharging, then chances are, charging is not working to full degree.
Feel the Heat
You can also feel the power supply’s side panel ten or fifteen minutes after connecting it to the 22. At that time, it should feel warm. But if you detect no warmth, then again, the Sony SRS XB22 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 fix this problem. So in this post, we offer reasons why the Sony SRS XB22 speaker may not charge when connected to power. Then we give possible fixes for this seen-often difficulty.
Sony SRS XB22 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 connect the speaker to the charger, and the charger to a power outlet, and battery recharging begins.
Note that when the speaker is running, the Power button also blinks when the unit needs charging.
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 situations may cause this. We list these below thus.
1.The Power Outlet May Not Have Voltage
The Problem
The AC or car adapter for the SRS XB22 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 XB22 not charging can also happen because the adapter is outputting SOME but not FULL amperage to quickly charge the speaker, even though its getting the correct power input from the outlet.
Note that as these adapters age, their output energy can fall over the years. So this power supply might not deliver the correct amount if it is too old. So you may see the speaker’s CHARGE lamp glow solid orange, but never go dark.
Please note that this speaker needs 1.5 amps 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 the maximum 5 volts at 2 amps (10 watts) for consistently fastest charging. Many commonly available USB power supplies meet these requirements.
3. The Battery in the XB22 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 aging cells, it may draw too many or too few amps, thus confusing the speaker’s charging circuits into behaving like no charging is going on. So the CHARGE lamp shows that charging is not happening correctly. It does this by either never stopping its solid orange glow, or never turning on when you connect the charger in the first place.
The Fix
To repair this, replace the battery. But realize that you can’t easily get the old one out of the 22. Indeed, changing the battery means that you must take the speaker apart, and this, be advised, is intricate work.
Also note that doing this likely breaks the moisture seal. So the SRS XB21 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 pick the right replacement. 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 3.78 volts at 2.8 amp-hours, or 10.36 watt-hours. But we suggest using only Sony certified batteries for this speaker.
4. The Speaker Might be Defective when the Sony SRS XB22 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 far outside of nominal. This can happen when the battery management circuits inside the XB 22 acquire problems. Note that these systems read the battery status, and switch off the charging current when they deem the battery full.
But when they break, 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 XB22. Why? Because the parts 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.
