Google confirms they're throttling your Pixel 10's battery

And there's nothing you can do about it.

Their Battery Health Assistance "feature" was optional in models 9 and below, but is now mandatory in the 10 and possibly subsequent models. And it will also throttle your charge rate. So shorter battery life, and longer charge times. YAY!

Google rates their batteries at 1,000 charge cycles before the battery drops to 80% capacity. Samsung, on the other hand, rates their batteries at 2,000 before the 80% level. Hmmm...

Apple got into trouble a few years back by introducing a silent throttle on some of their phones and had to offer free battery replacements, something that I took advantage of when I happened to be in Albuquerque for a day-long medical seminar that was literally across the street from an Apple Store. Now iPhones have a charge limiter - adjustable and can be deactivated - that by default limits your charge to 80%. When I got an iPhone 16 a year ago (my 13 Mini had strange problems that defied diagnosis), I set mine to 90%, and it reports that my maximum capacity is still 100% after 125 cycles. Sometimes the charge limiter forgets and my phone is at 100% when I take it off the charger in the morning.

Personally, I like to get 4-5 years out of my phones if I can and the only time I replaced a battery, that I remember, is when Apple throttled it and it did hit my battery life pretty badly. Normally I have no problem getting good battery life over the full life of my phone, but I don't spend all day texting or flipping through TikTok or other SM on it.

My understanding is that Li-ion is not harmed at all by being left plugged in. Older, especially lead-acid batteries were harmed because they get a "memory" if they are never discharged properly. This is much worse in batteries that are only discharged a set amount repeatedly, such as only down to 85% before being charged again. Eventually Those batteries wouldn't discharge *below* the 85% level.* As far as I know Li-ion do not form memories.

* The solution to the lead-acid memory issue is to let the battery discharge to various levels, including an occasional going pretty flat before recharging AND overcharging the battery a little bit sometimes. That is where smart chargers come in handy.

NiCads also had memory-effect problems.  The new 'salt' batteries will be interesting, whenever they get to market.

I hadn't read anything about the salt battery until now. Interesting.
One of the reasons I've been dragging my feet about solar power is that we are so hot here I'd need to build and air condition battery storage for Li-ion. Basically we are out of its "good" working temperatures for the vast majority of the year. At times we are in the "do not attempt to use" range. So the salt formula would be really interesting to me. I'm still using lead acid for my fence chargers as they are far more dependable.

Sodium Ion batteries are cool tech: much less expensive to make because of the availability of sodium vs lithium, and they can be shipped at zero volt charge.  But they're lower energy density, which makes them problematic for some applications.  Solid state batteries are also very cool, and that tech is rapidly evolving.  Amongst the problems with LIon batteries is the cost and water requirements to produce and also to recycle.  It's not that great of tech, except that it packs such great energy density.  This BBC article from last year talks about some of the alternatives: We rely heavily on lithium batteries – but there's a growing array of alternatives
