Sorry ST, I know you are trying to be helpful and you've replied to a ton of people trying to assist, but not sure where you are coming from with your recent comments. The Bose S1 Pro is literally proven to be a defective piece of equipment. Not SOME of the S1 Pro's. ALL OF THEM. Literally EVERYBODY who has bought one since it was released in 2018, has the battery drain issue. Whether or not they REALIZE that they have the issue, OK sure, many probably have no idea that they have a defective piece of equipment. Maybe they use it 5 times per week, and as such, are constantly charging the device, so they will never know the issue exists. So when you say "significantly less than 10%" of S1 Pro owners have REPORTED the issue, OK fine I believe that. But 100% (or close to it) of S1 Pro owners HAVE the battery drain issue, it's just that many of them don't know they have the issue, or the know about it but aren't concerned enough to call Bose (which was me for like the first 5 months of ownership).
Tolerance of components has absolutely nothing to do with this battery drain issue. Bose also has this issue with their new noise cancelling headphones. The QC35 does not. It’s a design flaw that is draining the battery when the unit is turned off. Their is something in the circuit design that is still engaged slowly draining the battery.
If the battery was seeing a open circuit when switched off there would be no drain, period. That’s the same as removing the battery. Obviously the fix is flawed or the service center in IN doesn’t know what there’re doing.
Seriously? I just got a pair of the new headphones delivered today.
If this was a design issue, we could expect all units to have the same problem.
Capacitors, diodes, and integrated circuit chips are components that might allow current leakage if they aren't up to snuff.
I have been unwilling to allow my S1 to sit unused for multiple weeks to determine if it has a problem.
I suggest all owners try to use their S1 more often, then they won't have a chance to discharge in a surprising manner.
O..

Maybe they all do but most owners don’t know it? I don’t think there’s any way for us to know unless Bose discloses information they don’t/won’t disclose (neither would other manufacturers).

There seems to be a gap between what Bose has said and what you want the product to do.
Please tell us what you'd like to see (all in one post) in the discussion linked below.
S1 Pro system: Feature Requests and Suggestions
Thanks,
ST
Hi ST, and thanks for the reply.
1, It would be good if any of my S1s had batteries that lasted long enough to achieve sleep mode.
2, It would be better of Bose had said what they mean by "we expect a fully charged battery in a new S1 Pro system will last 30 days with the power switch in the “Standby” (?) position if the system is using Firmware 7.1.5[1] or later." 90% would be my wish and expectation.*
3, Are all S1 Pros now being manufactured free from 'the battery drain issue' (accepting that there will still be an occasional failure in any manufacturing process)?
* 'The issue' is not to do with the life of a lithium ion battery, it has been demonstrated that they last as expected when removed from the S1 so "
The S1 Pro uses a lithium-ion battery. Individual battery performance will vary due to battery age, storage conditions, and the number of charge cycles. Bose does not guarantee how long a lithium-ion battery will retain its charge."
while understandable and reasonable, is a red herring WRT this discussion.
I have posted in the other thread as you requested.
Thanks again for your patience
Just for fun, for the curious.

As a professional who has to rely on his equipment, I make it a point to MAKE SURE that ANYTHING that's powered by a rechargeable battery has been completely charged up on the day before every gig.
The good news is that modern batteries rarely take more than a few hours to charge.
Prudent, for sure, but what if the particular bit of kit was bought simply because that was not an option?
Could you describe a set of circumstance where recharging the S1 within a day or two of a gig is not an option? 🙂

Generally, as you noted it's not a problem and the prudent thing to do is to fully recharge batteries before each gig. I've played more than 400 gigs with the S1Pros and this has been my go-to practice.
Also, now with the new firmware and Bose repairs to address the premature battery drainage issues, i think the examples I'm listing below are a thing of the past (at least for me).
But since you asked...
Things do happen from time to time and you realize you didn't do or didn't have time to recharge the batteries. In those cases it's nice to know you can depend on more than a few days from a battery charge.
For example (these things have happened to me; not recently of course, but before I installed the new firmware):
-- Following a late night gig, it's dark out and the weather's foul when I get home. I have another gig first thing in the morning. Both gigs were short gigs but nonetheless I had to unload and charge up my S1Pros and then reload them in my car before an already early morning gig -- just to be sure I have the proper battery power.
I play in numerous band (Gypsy Jazz, Reggae, Rock Variety, Jazz Trio), as well as my solo/singer gig which I do with my S1Pros. Each band setup requires different gear (PA systems, amps, different pedals, different guitars...). It's a constant game of swapping out one set of gear for another, and sometimes in the rush and confusion I realized I forgot to charge up my S1Pros.
Generally, I only use battery-powered equipment. Sometimes I forget to charge up my other battery-powered gear as well -- like iPad, eloop and lithium battery powered boxes for my pedals. If I've used them for only one gig and hadn't charged them up in a day or two, I don't have to worry about them. But with the S1Pro, I had to give pause.
I use to say, "Having to charge up my batteries before each gig is like having to check my spare tire before each drive."
However, I believe things are much better now. After upgrading my firmware, my recent test of battery life has shown 90-100% nearly a month without recharging.
So again, I emphasize: These are the types of problems I was having. However, thanks to the efforts of Bose I believe these problems may now be a thing of the past.

I'm an independent audio tech, doing events mostly in smaller venues. My gear is stored in an indoor climate-controlled storage facility where I have limited access to power. There is an electrical outlet in the hall near my storage unit, but I have to run an extension cable from my unit, and I may only use the power outlet when I'm there; I can't leave the extension cord in place and leave the building. The building management does not permit electrical connections within individual units, even if I pay the installation cost for an individually-metered connection.
I have 4 S1's that I mostly use for monitors at lower-volume gigs, usually with L1 Model II's as mains. I'm moderately busy, but I don't use the S1's more than once a week in a typical week, and sometimes less than once a month. I have met at least 5 other guys who do the same sort of thing in this building alone, and there are at least 7 similar buildings in town.
When I load up to go to a gig, my gear is organized that I can go in, pick up speakers, mixer, mics, stands, cables, lights, etc., and be loaded up in 15-20 minutes for most events, and take about the same time when returning gear.
To charge the S1's ahead of time would mean I go to my storage facility, pull the S1's off the shelf, remove the covers, plug them in, and *sit and wait* while they charge. Instead I run them off the mains at events; more cables, more outlets in use, less tidy stage, not what I had in mind nor what the advertising led me to believe. I could put all my equipment except the S1's into my storage unit, take the S1's home with me and haul them up the stairs in the middle of the night (two trips, I can't carry all 4 at once), set up some sort of charging station for them, and make sure that I remember to pack them on the next event that I need them, since they're not in the same location as all my other gear.
(I find it curious that my laptop and iPad both can be left for weeks without losing charge. My Bosch rechargeable drill sat in the same storage unit for 16 months without being plugged in; I hauled it out yesterday and both the battery that's in it and the spare indicate fully charged. Neither the laptop, nor the iPad, nor the electric drill advertise that they hold a charge for more than a few days; they just do it.)
Thank you.
It is puzzling why some S1s won't hold a charge for at least a couple of weeks.
(Interesting, my laptop drains its charge in a rather short period of time. I often have to recharge it before using it.)
Hi, Dave O'Heare.
Welcome to the Bose Portable PA Community. Thanks for joining us.
Have you updated the firmware in your S1 Pro systems? You can do it through the Bose Connect app, but here's a link to a way that is much faster.

They are probably need to upgrade their firmware to 7.1.5...
Thanks for the welcome, folks. I was just trying to give a real-life answer to Chet's question.
I do intend to update my S1 menagerie soon, thanks for the links on that. Is there any way to do it *without* being attached to the Internet?
And I'm obviously not up in arms over the whole thing; I do wish that they worked the way I want them to work, but sometimes I have impossible demands.

You have to be connected to the internet to install the firmware.
- If you can do it with a PC or a Mac with a USB connection from the computer to the S1 Pro - it's quick.
- If you do it using the Bose Connect app - the tablet or phone running the app must be connected to the internet. The connection from the tablet or phone to the S1 Pro relies on Bluetooth and it takes much longer.

Hi David and ST,
First David, thanks for the real-world examples.
As for the the new firmware: I upgraded both my units using my iPhone X, the Bose app, and Bluetooth. The first unit literally took several hours to install, and being a glutton for punishment, I also installed the second unit the same way -- and surprisingly, it only took about 15 minutes. So, as for using the app, your mileage may vary (as you can see mine clearly did).
In both cases the upgrade to the new firmware went smoothly and was successful. And as you can see from some of my previous posts, it was well worth it for me. With the old firmware, the best performance I ever received was 18 days with 70 percent power loss; with the new firmware, I'm at day 28 today and still showing 90/100 percent (or less than 10 percent power loss).
Yes -- well worth the effort to upgrade to the new firmware 7.1.5!
(Also, btw, the Bose cell-phone app is the best way to monitor your power level, showing level changes every 10 percent.)

Hi Peter. You might try turning off your iPhone and turning it back on. Can't hurt, and sometimes a rebooting seems to help.
Hi Peter,
Thanks for the update.
PZ posted:Hi ST,
now I did my part to 'get back to a place of trust' and loaded the new firmware. 🙂
Worked like a charm but now the (also updated) iPhone Bose app doesn't like to connect anymore. No problem to play music via bluetooth but the app doesn't see/find my S1 speakers anymore.
The latest firmware and Bose Connect app added enhanced security for Bluetooth connections. For some people (like you) this can break the connection between the S1 Pro systems and an iPhone or iPad especially if you are running iOS or iPadOS 12.x or later.

Not a big thing, I'm sure it will work someday again as we are talking about computers.
And now the funny part begins: will those boxes keep their charge! 🙂
