Galaxy Buds3 Pro - case battery drain overnight

[Blu-Ray]

So. Last night I charged the buds and case to 100%. Before bed I unplugged them from the charger after verifying they were charged to 100%. This morning when I went to check they had drained 3% overnight. So if its 3% over 8 hours thats ~9% a day. 10 days of no use and the case is dead? Seems a little bit excessive? 

I don't recall my airpods pro 2 ever draining. For that matter they hardly needed charging. The galaxy buds pro 3 i have to charge every 4 to 5 days of maybe 1.5 hours of use per day.

Checked to make sure they are seated properly and the charge ports are all clean. 

Is this drain thing normal?

Seriously, you are complaining about 4 to 5 days between charges.

No. I'm more about how the battery loss of just sitting there is excessive. For the competitor to air pod pros they really aren't that good. Price is comparable but the battery life is pretty horrible. They should be priced probably $50 less than what they go for on sale.

I consider horrible if the buds wouldn't make it through a day. I only have to charge my buds and case every 6 days with what is left in the buds and an empty case.

What is with men and battery life?

Having to only charge my Buds and case almost once a week IMHO is pretty darn good. How is that horrible?

I guess I'll pipe in:
Yes; rechargeable batteries (not just lithiums) are known to loose charge on their own over time, even when unused and not plugged in to anything. The thing is, a charge of 100% or a low charge is not natural for a battery, and puts a stress on a rechargeable.

If you take the parts and elements of a battery and assemble it together, there is a natural charge present, just like you can measure a charge out of a lemon. I have long suspected that if you measure the charge of a newly assembled battery, it would amount to 80% of the total possible capacity. I suspect that because it's often recommended and commonly practiced to put rechargeables (especially lithiums for hobby drones) at around 80% if one is going to store that battery for any significant time to minimize trickling charge.

3% is a bit large for a trickle, but don't forget that it is permanently connected to sophisticated, complex circuitry. 10-11 days may not be a bad thing; if anything, it may keep the battery healthy by keeping it in use.

[Pete-ohki]

It had just occurred to me. Those solar-powered, regular wrist watches, whether analog or digital, they don't use rechargeable batteries even though rechargeable button-cell batteries do exist. Instead, those watches uses capacitors to store charges. If those capacitors go bad, the repair person would have to desolder out the old capacitor, and solder in a new one -- and yes; that's a kind of service that requires a microscope to do.

Due to their size, I suspect that the buds themselves likely use capacitors as well instead of actual batteries. The case though probably does have an actual rechargeable battery.

These are a month old.

You are still getting 10-11 days of use. If the drain keeps increasing over the next couple of weeks, then you have a reasonable cause to bring them to a repair service.

[Blu-Ray]

I get 4-5 days of use. The case battery drains to 0 over 10-11 days.

[Pete-ohki]

I don't know about you, but for me, I would be sitting pretty with 4-5 days use (though I'm not sure if I'd be up in guns with just 1 either). 10-11 day without use seems tedious to me, but tolerable.
