Re: S1 Pro battery draining when not in use

Sam Spoons posted:

I need it to be good to go even after a few days since last charge. I go away for several weeks in the summer and it is not convenient to leave a relatively bulky device on charge ready for an impromptu session.

 

Charge it up to full, then take the battery out of the unit.  I believe it's a single screw.  The S1 will no longer be draining the battery.

Now there's a simple solution!

Re: S1 Pro battery draining when not in use

You can store the battery outside of the S1 and it will not discharge.

It only takes a small phillips screwdriver to do this.

Admittedly less than ideal but still bone simple and it works.

The battery will "go to sleep" after some time (30 days?) and you will need to plug in with the power cord and switch on momentarily to wake it up.

After that you can then run with just the battery.

Hope this helps,  _Roger

Re: S1 Pro battery draining when not in use

Thanks for the suggestion but it is simply not practical, the risk of losing the two small screws when removing or refitting the battery in the back of a car in a field is too great. I can power my other speakers from a separate battery pack and inverter so the USP of the S1 is lost.

So I still need to be close to mains power when I re-commission the S1 in case it has 'gone to sleep'! (where is the 'facepalm' emoji when you need it).....

This is the case regardless of whether the battery is installed or not. Bose put a sleep function in the battery to make it last longer. When lithium ion batteries are stored at too low a charge (below 40%) for a longer period of time, it adversely affects the life of the battery.

Re: S1 Pro battery draining when not in use

Hi Yendor

 Please see my reply to you here: Charging S1 Pro

Yendor posted:

Does your S1 charge fully, and the pulsing blue light shut off? I have updated the firmware. My S1 won't finish charging. I thought it had rectified itself, but next cycle it's back. Before I turned it on, ran some BT through it, shut off charged and it turned off. Not this time. I pulled the battery to do a reset, tried again, the same thing. I run a 12 volt battery pack to my mixer, so I got to charge that anyway before a gig. I do enjoy the speaker, don't plan to get rid of it, but sure wish these issues were solved. 

Thanks,

ST

Re: S1 Pro battery draining when not in use

So even if they solve the issue with the S1 discharging the battery I still won't be able to rely on it to be charged? 

Surely it's not impossible to 'sleep' the battery and wake it up without resorting to mains power? Sorry Bose, you have definitely dropped the ball with this one

The screws remain affixed to the battery cover when you unscrew them. There's no risk of losing the screws.

Roger and Michael are right.

Here's the information on Sleep Mode.

If you need to be able to leave the system dormant for more than 30 days, and won't be able to wake it up before a gig, the S1 Pro may not be a good fit for you requirements.

Re: S1 Pro battery draining when not in use

Thank you for being candid ST. It seems you have a brilliant product hamstrung by some questionable design decisions and some bad engineering (I never though I would hear myself saying that about a Bose product). My Camera batteries don't go into 'sleep mode', nor do my laptop batteries. However, if the sleep mode really does kick in after 30 days (and not when the batteries reach, say 40%) I could live with that but neither of the S1's I have briefly owned would hold charge anywhere close to 30 days so it seems a redundant feature just at the moment.

Anyway, back to my original question, have Bose made any significant progress tracing and remedying the battery draining issue? If so when can I expect to be able to buy a (second) S1 Pro that does not have the problem?

Re: S1 Pro battery draining when not in use

I've owned the S1 since April of this year and also have experienced the 'battery drain' issue.  Last week, I noticed an update to the Bose Connect app.   It required the S1 to be powered on to complete the update.   After the update completed, I decided to test the unit for battery drain.   So far, it's been exactly one week and the app is still showing 100% charge of the battery, even though it's been unplugged.   Has anyone else completed the update and had this experience?   I'll keep monitoring the unit for battery drain, but I'm hoping Bose has corrected the problem through the lastest software update.
