Here’s the reason why: Li-Ion batteries spend most of a charge cycle in an almost flat region. Simple battery gauges just read the voltage, so “Battery Low” happens shortly before it dies.
Neat, I didn’t know there was an actual reason for it!
Is this also why people say that keeping your charge levels between 20 and 80% extends your battery life?
The limits of the curve are a high stress situation for the chemistry inside, I’m not exactly sure about the mechanism, so take it with a few grains of salt.
Essentially there’s some growths (I think they’re called dendrites) forming slowly, all the time the battery is flowing charge. But it happens more quickly under adverse conditions, like the extreme ends of the voltage/charge spectrum…
KDE letting me know that my mouse’s battery is low for the past six months
(Okay I was too lazy to edit the image but all three sections of the battery are colored in red)Are you using a rechargeable battery?
AA batteries are typically 1.5V, but some rechargeable ones are only 1.2V. This leads to the product thinking the battery is always low even when it’s fully charged.
If you have a Li-ion rechargeable, you get the opposite problem. The battery is actually around 2.7V, and has a converter internally to step it down to 1.5V. You will keep getting 1.5V until the battery goes flat with no warning.
Ooh, that’s a good call, I’ll check. I think it’s just a standard 1.5v though.
I have 3M hearing protection ear muffs with built-in Bluetooth so I can listen to music at work. I have only ever seen the battery at 100%, or low
I swear I have the exact opposite, battery high for 3 days then battery low the next 2 before dying. Both earbuds and headphones from the same company.
My headset says over 80/60/40/20.
Notably that doesn’t start on full. Full charge just states ‘over 80%’
On the Turtle Beach headphones I have for gaming/working out, when she says “battery level medium” I always feel like she’s got a judgy tone in her voice.
Jabra?
Nope, Soundcore. My sympathies that more than one company does this!
