Camp Speaker Drains Phone Battery

[godfodder0901]

The flash light would be an easy one because the same cell as the battery pack which isn't LFP.

This is something that has been circling for some time. What was said is that it is the 7,777th cell in the truck, not that is was the 7,777th of the same cell. They have been taken apart by members of the forum several times and proven to be LFP cells as @Dark-Fx mentioned.

LFP makes a lot of sense in devices that spend most of their life sitting on a charger that cycles on and off without being used.

The Camp Speaker or the Flash light?

The Camp Speaker I wasn't aware of anyone taking it apart to see what kind of cell chemistry the battery uses.

The Flash light I can see people taking apart out of curiosity due to the whole 7,777th cell thing. I assumed it would at least have the same form factor. But, it turns out that it was just some marketing type silliness that doesn't mean much. The camp speaker battery can be the 7777+ cell(s).

This is a perfect example of why the camp speaker was a terrible idea, and instead they should have done some third party integration of a camp speaker. Some option they have that was actually developed/supported by someone else.

The use of USB-C Power Delivery means there might be glitches with how it interacts with various phones, and chargers.

Compatibility issues can happen with Bluetooth

Connection issues can happen due to it being pulled out and pushed back in.

There is a non-zero chance that the lithium ion battery inside the camp speaker might cause a fire.

The lithium ion battery potentially limits the life of the camp speaker. If the electronics/firmware are designed around the idea of it being plugged in all the time then its life should be pretty long. Way longer than the life of any lithium ion drill I've ever owed since I forget to charge then, and then a year later they don't accept a charge.

Much of their accessory development was hopeium based. It's a faster and easier technique compared to thorough validation.

Thank you all for your advice. Got back to my speaker after it was fully charged via wall plug and found the following:
If turned on and then plugged in the speaker charges the phone
If turned off and then plugged in the speaker charges itself from the phone

Neither allowed the phone to change these settings in the app and both situations still said "couldn't switch".

I experienced the same problem with a Samsung S6 tablet and a Pixel 7 Pro phone.

The tablet has no interface that I can find to control the USB connection, but it seemed to be depleting it's battery (no charging icon, percentage decreased while watching it) while the camp speaker displayed it's throbbing light near its USB-C.

With the phone, I saw the same interface as OP. I was unable to switch any options. When I tried, the phone reported it couldn't switch.

After trying to toggle both "USB controlled by" and "charge connected device" options off multiple times, and without power cycling the camp speaker, I unplugged and replugged and the phone switched to self-control and not charging the connected device. The charging icon also showed up over the battery in my phone's system tray. While I type this, my phone has gone from 44 to 47%.

It seems unintuitive and difficult to control, and I have no knowledge of how these devices handshake and negotiate, but it sort of works in this context. But when I plugged it back into the tablet, the tablet is charging the speaker again and I can't find any interface to hack at it.

I think the post above yours should do the trick for you. If it does I can update my initial post with that suggestions. Good luck!
