If your S1 Pro battery is draining when the S1 Pro is not in use (turned off) and not connected to AC power, please read the latest update
S1 Pro battery draining when not in use

I have two S1 Pro speakers.  Same age, both pretty much new.  The latest one i purchased with only a few hours of use has a battery that slowly dies over the course of a week or two when not in use.  The other S1 Pro battery lasts as it should.  Any thoughts?

Original Post

My experience is that both of my S1 Pro batteries die if not used for a couple of weeks. I spoke with customer service several times about this and they even sent me new batteries and replaced both of my S1 Pros (their engineers wanted to run tests on my units to see if they could figure out what was draining the batteries.) My newer units exhibit the same behavior so I'm not sure what the cause is. The customer service tech said they were wondering if S1 Pro BlueTooth was continually trying to connect so they suggested disconnecting my phone from the S1 Pro but I didn't get around to that before they replaced my original units. Unfortunately, no one followed up with me so I don't know if they discovered what the issue is. Frankly, this is not normal behavior for lithium ion batteries but I'm living with it and just keep charging mine to make sure they don't die. Here's the discussion I started: https://www.bosepro.community/...31#38892682227613531

Thanks Michael for taking the time to share your experience.  Do you find the battery lasts for the expected time when using it after a full charge?  

Yes, I find that I’ve been able to use my S1 Pro for three or four shows (I’m a magician) over a week without recharging. That’s about four hours. The only time I have issues with the batteries is when I don’t use it for more than a week or two.

That's good to hear.  I have been afraid to use mine for a performance without plugging it in first.  Thanks again.

I have the same issue where my S1 Battery depletes to a red indicator if not used for a week or so.  At first I thought that I had inadvertently flipped the power switch on when putting it in the bag, so I charged it and left it out of the bag.  The results were the same, a depleted battery with no actual usage.  I also positioned the power switch to the fast charge position and repeated my experiment to see if there was a difference. The results were the same, a depleted battery with no usage. Finally, I fully charged the battery, removed it from the unit and let it sit.  After a week, I reinstalled the battery in the S1. The S1 indicated that the reinstalled battery was fully charged.  This indicates that the battery is good and has no internal resistance that would cause such an issue. Therefore, the S1 has some sort of current drain while turned off, which is an unacceptable condition and presents a challenge as the S1 will not be fully charged when needed if being transported and away from an outlet for any length of time.  To me, the purpose of the S1 is to do just that for busking etc. and it is the reason I purchased it. I am respectfully requesting through this forum that Bose determine what the issue is and correct it.   

Hi Real Piney,

Thank you for joining the Bose Portable PA Community.  Welcome.

I'm sorry your S1 Pro system battery is draining when the system is idle for an extended period.  I appreciate your thorough diagnostics and testing. 

Please call Bose Support and they will take care of you.

Well, it appears that I too have been afflicted with the dreaded battery drain issue.  I bought my S1 about a month ago, charged it and it's been plugged in until a couple of weeks ago.  I've only used it a couple of times here in the house, testing set up, etc.

We went to visit family over the Christmas holiday and I took the S1 with me, but never got the chance to use it.  Today, after 2 weeks of being unplugged and turned off, I wanted to make test it to make sure the battery hadn't discharged.  Unfortunately, it is completely discharged and will not even turn on.  Bummer!  I'll call Bose Support today and see what they say.

I hope the figure this out soon.

 

Quick update.  I spoke with Bose Technical Support.  They are sending me a replacement unit.  The process was pretty easy and straight forward.  I got a shipping label and will return the  old unit once I receive the new one.

When the support rep asked if I had other questions, I asked if Bose had found out what the problem was and wanted to make sure I didn't get another defective unit.  She said that the issue was tracked down to a capacitor issue which has been resolved in the new units.

Hi Everybody,

We'll have more information about how to determine if you have one of the affected units by early next week.

If you have a problem now, (with the battery discharging when the system is off for several days) please call Bose Support.  

Stay tuned, we'll have more information next week.

Thanks!

I wonder when they figured it out because both of my current units are still draining the battery when not in use and one of the was replaced in early December. So far, I've had five of these units and they all have drained the batteries. (I bought two last spring. Bose replaced the first two when I noticed my issues. Then, in December, they replaced one of those when it started draining from 100% to dead in four days.)

Hi Michael,

I'm sorry you've had this poor experience with S1 Pro systems.  

This is all late-breaking news and we'll have more details for you early next week.

Thanks for your patience.

No need for apologies. Bose has been very responsive on trying to take care of it. While the circumstance hasn't been perfect, I've been able to use my units regularly and have just had to go to the extra step of checking to make sure they were fully charged the day before. Bose has replaced my units multiple times, providing return shipping labels and overnight delivery. I posted regularly because I was hoping Bose would figure it out (I was one of the first to post about the issues months ago.) I'm very satisfied with my S1 Pros and am truly hopeful that they really did find the issue. Once the batteries stay charged like they should, I'll be even more satisfied with them!

I have 2 S1 pro speakers.  One without any issues and the other one has the same battery issue as you have been experiencing. I haven't called Bose support on this yet but I plan to soon.  What I just started doing in the meantime is taking the battery out of my second S1 Pro after it is fully charged and putting it back in when I need to use it.  Temporary fix that works for me as I dont use my second speaker as much as it is more of a back up speaker and practice speaker that I can easily plug in when used at home.  I have decided to so this as from what I have heard, the battery is not the issue....it is the speaker that is slowly draining the battery when it is not in use. 

For guitar players and street performers the battery is a useful feature but that is probably different for keyboardplayers and many bands who need electricity when performing. I wonder why Bose does not offer the S1 pro without the battery. I have bought one a year ago without the battery. I am a keyboardplayer and would like to buy a second one, but I do not need a battery. I don’t want to pay 145 euro for a battery I don’t need. So I hope Bose offers the possibility of buying the S1 pro without battery, taking into account the different needs of musicians who want the use the S1 pro.

So I just received my replacement S1.  The battery is totally dead on arrival, not even a red light.  I don’t consider this a good sign as I would have expected the unit to have held some minimum amount of a charge. So I will charge it up and see what happens next.

I too just received my replacement S1 and the battery appears to be DOA.   It didn't start charging at all when I plugged it in.  However, when plugged in, it didn't start charging until I turned the unit on.    I'm guessing this appears because the battery is in "sleep mode" initially.

Have you had a chance to test to see of your battery is being discharged with this new unit?

 

Yes.  The battery state of charge indicator (blue lights) indicate the battery  was at 10% after 6 days.  I was doing some research trying to determine exactly what I was looking at with the battery “fuel gauge” (flashing blue lights or the indicator on the Bose app via Bluetooth) and what it really means.   Since a lithium ion battery cell has a self discharge rate of about 10% per month from a chemical perspective, it seems wrong that the battery is at 10% capacity after one week.  The indicator however, does not actually tell you what the battery chemical state charge and condition is because this is a smart battery.   battery itself contains digital circuitry which regulate the charging sequence, measure the cell temperature for protection and calculates the battery state of charge, based on how much current it took to charge the battery back fro its depleted state.  This is done using a method called coulomb counting (in case you want to look it up).  Laptops use the same type of smart batteries and the same type of indicator circuits.  I know from experience that the battery capacity indicator for a fully charged and turned off (not in standby) laptop does not deplete as rapidly as the S1 does.  Bose will have to tell us if the battery indication dropping from 100% to less than 10% within a week is acceptable performance for this system by design.  

Hi Everyone,

We are aware of the issue with some units losing their charge and are currently implementing a fix. If you feel you are experiencing this issue, please contact Bose Support.

Please charge up the battery, and let us know if you have any problems.

The S1 has been charging on trickle charge for a couple of hours and appears to be fully charged...the blue light stopped flashing and is no longer lit at all.  I'll let it set plugged in over night and try it again in the morning.  If it appears to be good, I"ll let it set for a few days and check again.

 

I'll test it out but I'll be using it this upcoming weekend and that will interrupt the "long idle test". 

I'd think that Bose would just make note of everyone that has this issue, ask them to keep it plugged in when not in use, then send the new units when they have a definitive fix.

Okay, I understand. Mine are rarely idle for long too.

We're watching this discussion thread closely.

Have a great gig.
