Discussions about the Bose S1 Pro system

Bose S1 Pro

Designed for musicians, DJs and general PA use, the S1 Pro is the ultimate all-in-one PA, floor monitor and practice amplifier that's ready to be your go-anywhere Bluetooth music system for nearly any occasion. 

This is the place to discuss the S1 Pro system.

Seems like not much of a fix at all, judging from the experiences coming in.

By way of contrast, I had occasion to use our Dyson handheld the other day which hadn't been used or plugged in for over a year and it was fully charged. Why aren't our S1 Pros capable of this? And more importantly, why is this fix not really as fix? 

We need some proper answers here, please.

Will not be sending mine in until there is a proper proven fix.

So one has lost >25% in 9 days, so that on is definitely not fixed*  Let us know about the other one if you can leave it for another week or so, mine lost less than 10% in the first 10 days but was down to 40% after three weeks. If you can use the app it resolves to 10% rather than 25% increments.

*you second S1 may have lost up to 24% as the flashes don't fall below 4 flashes until it reaches 75% or less.

This all sounds to me more like a hardware design flaw than a software "fix".

I'm grateful that I can keep mine plugged into my grid-tied solar panels all of the time and don't travel with them except to and from the gigs.

That's the way it's been done since I got them right after they came on the market.

Great 5 hour gig (plugged in) yesterday...

Yes, it’s a hardware issue.  They’re replacing hardware but so far it doesn’t seem to fix the issue. 

Dj Verrett posted:

I got mine back from repair on 12/26 just checked them today and one has 3 flashes and the other has 4 flashes. The whole repair took about 2weeks from the date I shipped them and received them back. 
Thank you Bose!

 

Try to use the Bose app to monitor the battery in 10% increments.   The three flashes means one of your speakers is below 75% charge already. That’s a significant loss in a short time.   Your other one is indicating Over 75%, but not how much over 75%. 

What I'd like to see fellas is for Bose to officially announce here,

"What percentage of battery drainage over what time we should see with the S1Pro after it has been fully charged and not in use." 

Until then, everything is guess work. Without their input, speculations and assumptions will go on forever...

Hi Everyone,

Thanks for the lively discussion.

I'm looking into the individual reports about repairs and results. While it's not always apparent in a forum like this, people's individual situations and Bose service policies may vary by location. It can be confusing to draw parallels with limited information.

Bose has not published a threshold for battery drain while the system is idle.  There are several factors that can affect this. Also, the blinking lights

and the percentage charge shown in the Bose Connect app are rough approximations of the state of the battery charge. The charging rate slows as you approach 100%. The level in the Bose Connect app may report 100% before the battery is fully charged.

I have one unit that is fine, the other I returned because of the issue. I see units being returned following service that still have the issue, so whatever is being changed, updated, repaired isn't working.  I need to replace my returned S1, but don't want to deal with the charging issue, as I don't normally gig with two units, but need it for larger venue's. So, it would sit normally. I've seriously considered the JBL Compact, but from what I've seen, it isn't up to the S1 performance. So waiting for Bose to fix this issue, or order the JBL, or maybe EV or someone else will join in the market.

Hey folks,

new to the forum and have been looking at this thread since the Christmas holidays. I gig regularly on the weekends as a salsa pianist and use my S1 as a monitor.

On my last gig in December, I realized I couldn't even start up my s1 using the regular battery. It also failed to charge so the battery was no longer working. Since the battery was within the 2 years warranty, I was able to exchange it for a new one.

I decided to do the drainage test once I got the battery.

Thurs. Jan. 2 - 100%
Friday Jan. 3 - 90%
Sunday Jan. 5 - 80%

Called Bose and they recommended I send it in - going to hand deliver the unit sometime this week for a speedy return delivery.

Hope their fix will work.

Keep you posted.

UPDATE on Post-Fix battery status:

Dec 23, at 100 percent.

Dec 29, at 80 percent.

Jan 1, at 70 percent.

Jan 4, at 60 percent.

Jan 6, at 50 percent.

(Approx. 50 percent drainage after 14 days. Losing on average about  3.5 percent a day.)

During my gigs, I've seldom used 50 percent of my power. So worse comes to worst, even at a 50 percent power loss, it should be enough juice to use for a 2-3 set gig -- even after two weeks without charging. (And of course, I probably wouldn't go two weeks without charging under normal circumstances.)

With this said however, a loss of half my charge in two weeks does seem excessive. I would like to hear from Bose about their assessment of this situation. Thank you ST for running that down.

I will continue to report my battery levels -- every two days if possible.

ST: would you say it's even worth it for me to bring it in to have it repaired? If I'm going to make the effort to bring it in/mail it in - only to have the same result (or worse) regarding the battery drainage?

Can BOSE guarantee that my battery drainage issue will be better after repairs?

(I will wait for a response before I proceed with bringing in the unit)

Hi, MRDL.

MRDLC posted:

Update: Not sure if any of you have gotten this firmware 7.1.5

Product Update for the S1 from the Bose app (on my iPhone).

ST: Wondering if this is related to the battery drainage?

The firmware version 7.1.5 release notes say:

  • Supports power-saving features
  • Optimizes battery performance
  • Enhanced security for Bluetooth connection

These changes to do not resolve the battery drain issue that we are discussing in this thread. As I mentioned in my post above, I should more information about the repair process soon.

If you use the Bose Connect app, it will download the firmware update and notify you when it is ready to update your S1 Pro.  It's much faster if you use a computer to connect to the Bose site and do the update with a Bluetooth cable. Please see the link below for details.

S1 Pro System Updates

ST

Hey folks,

just and update on me regarding my battery drainage. 

Note: I did plug in the unit to download the new firmware 7.1.5 a couple of days ago, but I made sure to leave it at 80% by the end of the night, so as to continue monitoring battery drainage from the time I started on Thurs. January 2nd 2020. Here are my updated stats (including post firmware update):

Thurs. Jan. 2 - 100%
Friday Jan. 3 - 90%
Sunday Jan. 5 - 80%
Wednesday Jan. 8th - 70%

Looks like drainage is happening still. Have been reading on the site and it seems like there hasn’t been a guaranteed fix for this. Is it possible that the claims of battery life spanning a 5-6 months are not true, ST? (As much as it is disappointing, I’d much rather have the truth and a runabout where I’ll be bringing in the unit for repair, only to be disappointed with the same quality of product). 

Any updates about a proven and guaranteed fix, ST?

Thanks in advance for all your input and help regarding this matter.

 

Someone from Bose in England called me today twice.  It sounds like they did identify the bad parts and there were issues with the early repairs on mine. At his suggestion I’m going to have my wide send the one back that was returned in January 3 without testing because they think it wasn’t fixed right. That way I’ll have both back and fixed basis I get home in February.  

I will say that I not feel confident that they had save this under control.  I hope they prove me right. Unfortunately it means done of us who jumped in this will be inconvenienced more than others.  

Thanks David for your input. I too had a similar experience with an English Bose rep today.  Apparently, my unit was repaired with a faulty part and they're working with me to correct the problem.  I await further correspondence with them, but at this point I'm satisfied that Bose is working with me to resolve my S1Pro issues.

That's not encouraging. I picked mine up yesterday and fully charged it before switching off at around 9 p.m. (it was completely dead after unboxing it). I will leave it until tomorrow evening then check it for the minimum switch on time and repeat every couple of days until I have an idea if it is performing better than before I returned it. If it's still reading 100% a week on Tuesday (after 14 days) I'll probably leave it another couple of weeks. If it's truly fixed it should not fall below 90% in less than 90 days.

Hi MRDLC,

You've established that your S1 Pro needs to be repaired. Further testing isn't necessary.  It needs to go to Bose to be repaired.

As you can tell from reading the reports from DavidE2 and Archtop Eddy above, Bose has tracked down the problems with the faulty repair process they experienced.  Bose is working individually with others who may have similar problems.

I know I haven't addressed all your questions. I hope to have more to say in a day or two.

To all:

Please note: This issue does not affect the battery life while you are using your system. The battery drain only happens when the S1 Pro system is off and not connected to AC power.

ST is absolutely correct.  Yesterday, I got a last minute call to cover a noon to 3 gig for a friend and then a 6 to 10 open mic.  My rig is a T4S mixing vocal and guitar to 2 S1 Pros.   I went directly from the first gig to the second.  At both gigs, it was easier to run one of the S1s on battery than to run an extension cord so that's how I did it, taking turns on the one running on battery.    Both ran fine for the entire time, no issues at all.  That's 3 hours at gig level on one and 4 hours on the other.

At the first gig, a solo piano player was setting up in their "big" room for a gig later in the evening.   He had the typical 15" speaker/sub rig.   He came over and listened to me for a bit and said he was amazed how good those "tiny" speakers sounded and how he'd love that portability.  

 

Faulty components are extremely rare, that two or more 'repaired' S1's still have the problem is highly unlikely to be purely down to faulty components.

Surely the techs have a means of measuring the current draw on the battery with sufficient accuracy to know if the device still has the issue* meaning we don't have to leave our newly 'repaired' S1 Pros unused for two or three weeks to check?

ST? Are currently manufactured S1 Pro's guaranteed to be free from the issue (I hope to buy a second but am reluctant to do so until the battery drain issue is definitely solved)?

* I know it will only be a few mA but my 30 year old Avo DVM can measure a resolution of 1 mA or less.......

My sense was that they screwed up and didn't put in the new components.  An issue at the repair facility, at least in Indiana, now corrected.  I did ask about new ones and the ones being made now have the corrected component.  But if you buy one in a store could be old stock and have the old component.  I didn't ask them if there was a way to tell.

I guess the wisest thing to do now - assuming you haven't already sent yours for repair - is to wait until someone who has had the proper repair done, has had sufficient time to test it and see if the drainage problem really has been fixed. I find it quite surprising that having developed a fix they then screwed up in applying it. Almost unbelievable...

Just my two pen'orth... 

I know that my dealer had sold out and was waiting for new stock to arrive at the UK importer. When I took mine back he'd got a couple of 'the latest batch'*. Whether that 'new' stock has been hanging around the system for a couple of months I can't tell but IIRC the app does show a date of manufacture which would be helpful. 

* I asked if he could charge one up and leave it in the stock room for a couple of weeks but he said they would be sold well before that.....

So first of all, what an INSANE thread, I honestly can't believe the S1 Pro has had this issue. So, I bought my S1 Pro in Sept 2019, I have the Drain Issue (it drains in 14 days or less). Based on the thread, I should call tech support, fine. But here's my question, knowing what we know now, for someone like me who will use this infrequently, should I be removing the battery in between use? Or is the FIX really going to FIX THE DRAIN!?  I mean, I read where ST says that the battery draining 100% doesn't hurt the battery at all? Really? I mean, here's what they say about E-Bike batteries, on a top E-Bike website, "If a battery is left empty for an extended period, however, it can become damaged and/or non-functional. ".  So Bose's battery is a magical battery technology that doesn't degrade when it sits empty for a prolonged period?  Anyway, the bottom line, once I get it repaired, is it still going to drain, but it just takes months to drain all the way to 0%? Am I supposed to charge it monthly? Weekly? Remove battery when not in use? This is crazy because I have a 6 year old $200 Samson Battery-Powered speaker that can sit for a year or longer and doesn't drain to 0%, don't have to worry about removing battery, nothing like this.  Someone break it down for me, where are we at with the "Best Practices" for owning an S1 Pro that rarely gets used?

From what I know about this type of battery (I've had rechargeables that have drained to zero and then won't take a charge)  and my personal experience I suspect the best things to do are:

1) What I do - leave them plugged in all the time at the "off" setting ('trickle charge') and keep them charged at all times.  I use mine 3 or 4 times a week for practice and one or two times a week for gigs.

2) Take the battery out when you know you're not going to use them for a while.  Then plan ahead, put battery back in and charge 'em up a day or hours ahead of a gig.

Hi Aaron. Welcome to the forum.  For you and others concerned about the battery drainage issue, allow me to put my thoughts here and give MY perspective on it. (I emphasize MY because this may not be others' point of views)

I have two S1Pros and have used them strictly in battery mode at about 500 gigs.  They have never failed me during performances (ranging from 1 to 4 hours).  The sound is perfect for what I need -- singer/soloist in restaurants and small clubs.  I marvel at the weight, size and convenience every time I use them.

As a practice, I charge my units to the full charge before each show.  As a result, the drainage issue is not a problem for me in real world applications.  Even if it didn't have a battery drainage issue, I would still charge it up for each gig. I prefer a full tank before I start playing.  Additionally, I carry the power cords so I could (in most cases) plug it in an outlet for the juice.  I prefer to use the battery power for its convenience and minimizing setup, but as I said, if necessary I could just plug it in at most gigs. (Now in some cases, you just can't charge up before each gig so having a battery level and charging system you can depend on is important too.)

For those wondering whether to get a S1Pro or not due to the battery drainage issue -- I say consider whether it should be game changer or not. The Bose S1Pro is a fantastic compact personal PA system, and with proper consideration (keeping it charged before gigs), and it shouldn't be a problem.  (Also, the newer units may not have this problem.  However, this is something I am not sure about)

Now you may ask, why all the concern and discussion about the battery drainage issue. The simple answer is that the system was built to have the battery option and it should work correctly to provide that. We should be able to expect it to stay charged after it has been charged -- at least for a reasonable period of time. Without the discussion about this problem on this forum, Bose may or may not have become aware of it.  Either way, Bose is working to fix it and has stepped up to getting each of our S1Pros working correctly.

I believe this is because Bose understands they have different customer audiences (audiophiles, home entertainment, etc.), and in our case as musicians many of us depend on our products to work correctly for a living.  They appreciate this higher level of need and expectation, and Bose is committed to supporting our needs.

-- On another point, I noted earlier I have two S1Pros. Both have been sent in for repairs and the first one apparently wasn't fixed correctly as it is still losing about 5 percent of power a day when left unplugged.  In my next message to this thread I will outline where I stand on all of that.

 

The bigger problem is that Lithium Ion batteries can, under certain circumstances, spontaneously combust or even explode. It's very rare but the Boeing Dreamliner battery issue was an extreme example. It is known that batteries running at 70%+ charge levels air significantly more likely to have the problem and it must be pretty rare given the number of devices with Li-Ion batteries we all own.

The answer for long term storage though is to only charge Li-Ion batteries to 50-70% if you are leaving them for an extended period as the likelihood of a catastrophic failure is pretty much negligible when the battery is below 70% charge. But if your S1 completely discharges in a couple of weeks or less (as my first one did) you then have the problem of the cells developing 'whiskers' between the electrodes which mean the cell is rendered U/S.

If you S1 can hold around 50% of its charge after 30 days the 'sleep mode' will kick in reducing the battery drain to nearly nothing and it will then sit happily for a couple of years. That doesn't help those with "the issue" though as their S1s will be at zero long before the battery enters 'sleep mode'.

OTOH, if you are using it two or three times a week or more then you would never have known there was an issue if you hadn't stumbled across this thread would you?

FWIW I do need to be able to leave my S1 for two or three weeks a couple of times a year and expect it to hold sufficient charge to run for a few hours which is how I discovered I had 'the issue'. Yes, I could charge it the day before, usually, but it's an expensive, premium, bit of kit and it should work properly.

UPDATE on Post-Fix battery status:

Dec 23, at 100 percent.

Dec 29, at 80 percent.

Jan 1, at 70 percent.

Jan 4, at 60 percent.

Jan 6, at 50 percent.

Jan 8, at 40 percent.

Jan 10, at 30 percent.

(Approx. 70 percent drainage after 18 days. Losing an average of 5 percent a day since Jan 1. At this rate it would run down from full charge to 5 percent or less in three weeks.)

Bose has asked me to return this unit (No. 1) so they can re-fix it.  Apparently, they used bad parts the first time around. I intend to return it but first...

I have two S1 Pros. My unit No. 2 was returned to me today -- "fixed". I plan to keep both my units for now and fully charge both tonight. I will then compare the battery drainage levels of both units with one another.  In this way I can determine if Unit No. 2 returned to me today is maintaining a battery charge better then the still faulty Unit No. 1.

I hope to be able to conduct this analysis for two weeks (at which point I may need to start using a unit for gigs). Hopefully by then I'll have some sense on where things stand and I will return the first unit for the follow-on repair.

I will keep you abreast of the result.

My S1 has been home 5 days now, collected Tuesday afternoon. It was completely flat when I got it home so I fully charged it Tuesday afternoon and left it switched off an unplugged.

Tuesday 7th 9 p.m. - Full charge

Thursday 9th 9 p.m. - 100%

Sunday 12th 1 p.m. - 90%

Is think we can conclude that the 'fix' is no such thing. And my replacement S1 is significantly worse after the 'fix' than before (it was still reading 100% after 10 days before they 'fixed' it.

Before I return it for refund ST can you throw any light on the matter?

An additional thought, surely the Bose techs can measure the current drain from the battery? IIRC the battery spec is that it is a 2000 mA/H battery so 10% capacity would be 200mA/H. For it to lose 200 mA/H of capacity in 5 days would require a current of 1.66 mA. My '80s Avo DVM can measure down to micro amps so I'm sure the techs can easily test to see how much current an idling S1 is drawing?

Hi, Sam Spoons.

I've sent you a private message to get some details about your repair order and contact information.

Please watch for a red dot at the top right of this screen by your name. Click your name and then Private Messages.

Thank you,

I have my return label from Bose for the “fix”. I haven’t had a problem yet because if I’m not using it for more than a week or two I simply remove the battery (this does work). Now I am wondering if should wait until someone who has had it returned posts here with positive results?
