Charging a lithium battery to 80% only?

I had an iPad that I bought 5? years ago and I could leave that thing in sleep mode for literal weeks at a time and I'd still have a mostly full charge. I "upgraded" to a Pro 2 years back and the first thing I noticed was it'd go from a 100% charge to 60% to even 40% overnight. All apps closed, freshly rebooted and did nothing but charge it the previous night before unplugging it. A lot of comments online say "This d…

The amount of background crap has been steadily increasing on Apple devices, you're probably right in your observation that it's related to wireless/Bluetooth. I have a iPad 2 (yes, the one from 2011) which I keep around with the plan to turn it into a house-automation screen and I'm always surprised when I look at it every 2-5 months to see it still has a decent chunk of battery left. And it's in sleep, not turned o…

I've given up trying. If a device is willing to lie to me and only charge to 80% while saying it's charged, great, but all of this "try to stay in a range" logic flies in the face of reality. Every device I use besides my cell phone, Nintendo Switch, and Nintendo 3DS has atrocious power drain when not in use. OS does not matter. Windows laptop, Linux laptop, ChromeOS laptop, Android Tablet, Amazon Tablet, you name it…

> Those are replaceable and cheap to replace every couple of years. If you specifically seek out devices with cheap replaceable batteries, sure. But this isn't the case with a lot of devices.

The cost to replace the battery on iPhones, which most people would consider to be “difficult to replace” is only $100 directly from Apple. Really seems like paying an extra $100 every 2-3 years is a decent deal for something that has 20% more battery.

I wish they would label it so that it shows 100% charge when it's actually charged 80%, and then give an option to 'overcharge' a configurable amount till 125% (the current 100%). That way it will make people aware that they are reducing the battery life by overcharging, and be picky when they overcharge. But this won't happen because reduced battery life is a big direct and indirect(by reducing performance like Appl…

> "What Apple did was clock down the CPU of iPhones with degraded batteries in order to reduce peak load" It wasn't what Apple was doing that was the problem, it was the fact that they were initially quite secretive about it! People just started noticing their phones slowing down without explanation. Now days iOS tells if your battery no longer supports peak performance, which is the right thing to do. > "Yes, they s…

I wonder how many products have components that downgrade under specific situations and they never explicitly tell the customer - and most customers don’t ask because it’s “complicated tech” they don’t want to know about it.
