Many Sony speakers, including the SRS XB01, feature a charging status light that glows orange while recharging them. Sometimes though, this light stays on. E.g. It does not turn off after way more than the specified charge time once you connect the charger. So in this post, we offer reasons that this can happen, and suggest possible fixes for this common problem.
Why Sony XB01 Orange Light Stays On
It’s normal that this orange light glows while the charger cable is supplying power to the XB01 for up to a few hours, until the battery completely fills. Then, under normal circumstances, this light should go dark, whether the speaker is running or not.
But if the orange lamp does not go out, a couple things might cause this, and we detail those below.
1. Your AC or Car Outlet May Not Have Electricity
The auto or home adapter you’re using may not deliver any power because it is not receiving any in the first place. This can happen due to a broken AC or car circuit, tripped circuit breaker, blown fuse, faulty wiring, power failure, and the like.
Check that your outlet has power by testing it by plugging in a lamp or other device to it, to see if it works. Reset circuit breakers if tripped, and if the outlet has a light switch that controls it, then be sure that that switch is in the ON position.
2. Your Power Adapter is Too Weak or is Defective
The Sony XB01 orange light stays on, perhaps, because the charger adapter you have provides SOME, but not ENOUGH, recharging energy. Or, its output power output has weakened over time. The speaker requires at least 0.5 amps of charging current at 5 volts (2.5 watts) from the supply to fully recharge in the specified time of 3 hours.
The fix in this case is to replace the adapter. Note that many USB adapters can deliver this amount of current. So you needn’t be overly picky about which adapter to buy… at least not in terms of its power delivery specs. Nonetheless though, get a well-known brand for reliability.
3. The USB Charging Cable is Too Long, Too Thin, or is Defective
The USB cable can reduce the charging current even if your supply is working properly. This might happen with very long or very thin cables.
To address this, use as short a cord as is practical. Or, switch to a thicker, higher current handling cable. We recommend keeping cable lengths to six feet or shorter, and to choose a cable that is certified to carry at least 1 amp.
4. The Speaker’s Battery Might Be Faulty
As lithium ion batteries age, they can spoil. That is, 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 charge current. We believe that the Sony SR2 XB01 monitors this. Then when the charge current falls to a value that it interprets as the battery being fully charged, then it shuts off the orange CHARGE light. But defective battery cells may not behave this way, and instead, continue drawing excess current. Therefore, the current never falls to the fully charged value, and so the orange lamp never turns off.
To fix this, replace the battery, although you can’t easily get to it in the XB 01. Note that replacing the battery means speaker disassembly. Furthermore, taking the speaker apart will likely break the waterproof seal, so that the speaker no longer resists damage if you get it wet. Plus, breaking this seal may also change the sound of the speaker. Therefore, battery replacement should be done only by someone who can get the right battery, and can restore the seal as they reassemble the speaker.
5. The Speaker Might be Defective when the Sony XB01 Orange Light Stays On
Even if you have a large enough power supply and cable with a working battery, the charging current that actually reaches the battery may be too high or too low. The can happen when the battery management electronics inside the XB01 fail. These circuits monitor the battery and shut off the charging current when they deem the battery as fully recharged. But when they malfunction, the battery might get no charging current at all, and so, never recharge. Again, in this case, the orange light might never turn off while the charger is connected. You would also notice that the speaker doesn’t play as long before going dead. Or it might not play at all except when you have the adapter connected.
The most practical solution here, given the relatively low cost of the 1, is simply to get a new speaker. The circuits in this model are quite miniature. So unless you can replace the system board(s), just buy another speaker.
