You're right that I don't know what "Battery Idle Priority" is. I tried looking it up but Google unusually found only one result - your post under this article. Not a single other mention. And no, thank you, I'm not going to root my phone. You wrote that "the charging input current can bypass the battery totally and only powers the device's internal components directly." I never looked at the boards or experimented with it, but that's how a laptop should behave and always appeared to me to behave that way. It should work like that as Li-ion cells generally can't be trickle charged. At some point, there has to be a hard cut-off. As I understand it, charging circuits for Li-ion cells typically have a timer as a last resort limit to prevent accidental overcharging (it's simple and more fool proof than integrating charge from current; but again, I won't claim to know all the charging solutions on the market because I don't). Because it's tricky to measure state of charge at high states. Once the battery was charged, laptop went into AC powered mode and stayed there. I have never observed any cycling between charging and discharging. To me, that would be really stupid. So stupid it's unthinkable. Why would anyone do that? As I said, I never looked into how they do it. Which chips they use, what the datasheets say. And at least in the "dumb phone" days, I would have expected the exact same behaviour. And again, I don't recall a single phone that would show cycling. At idle, no phone call. With a phone call, I believe it could cycle (meaning cell would discharge during the call and top up after the call). But again, I never verified. I've never tried connecting a cell simulator instead of the actual cell to monitor what's going on.
While it's not my field, I read a fair share of white-papers from companies like Saft. Apparently, I know enough for them to sell me cells which are restricted and not available to the public. I haven't yet burned down my house. Yes, when I wrote that it should take days, it was an understatement. Call it laziness. I never needed that number (I know how much I should charge them for storage and how often to check them, that's all I need) and was more concerned about not overselling. Point was that charging won't restart in a hurry. If you actually unplug the laptop from time to time and use it, it should charge just once.
I call that honesty. It always appeared to work that way and I never felt the need to check. I have much more interesting projects to spend time on than digging around a laptop charging circuit. If I ever noticed the cycling you speak of, I would have investigated. As I wrote, to me, the notion is incredibly stupid and I would find it unbelievable that someone did it, motivating me to investigate. Never noticed, never investigated. One difference between phones and laptops was that it was pretty common for laptops to spend significant time on a charger. With phones, however, you'd generally disconnect them once they were recharged (at the earliest opportunity). So, to design a laptop the way you suggest would be really stupid. A phone, not so much. And while I never investigated, over the years, I left quite a few laptops sitting on a charger. Sometimes for months at a time (of course, with the battery kept at a lower state of charge). Never noticed the batteries suffering. Constant cycling would have surely shown.
How do you know it's "EXACTLY" 60 %? Because the phone told you? Don't make me laugh. If you know so much, you know the difficulties and uncertainties.
I have never seen anybody write so much about what they don't know and why they don't know. If you don't know, don't comment. just STFU.
Really? Years ago, Android developers have studied the problem. Understood the problem. Built a solution for the problem. Then released it. Knowledgeable users have actually also understood the problem and downloaded the solution and used it to solve a daily problem - people like me. And we have moved on to more important things in life.
Sharing it on this forum is just a common decency thing on our part.
Yet, ignor-anuses like you STILL crow about how you don't know what the problem is and how you cannot find info about it. You are the perfect example of the idiotic Facebook/Twitter generation who are empty vessels but want to write rubbish.
You're so dumb you can't even Google the name of the app I have provided!?! Yet you crow about how my comment - here - was the only thing you could find? Wow - your computer using skills are indeed mind-bogglingly Neanderthal. If you can't even find the app to do things or learn how to root, WhoTF are you to question what battery level I see everyday and can confirm everyday with tools you can't even begin to understand?
If you don't know, just keep quiet, instead of opening your mouth and confiming to the world your stupidity.
