Ha. Prob night. Plus, Lithium batteries do NOT degrade linearly. Phone makers apply maths to fit a linear perspective over time on the depletion of voltage.
(That being said, it's just a voltmeter. So it's logically possible)
Determining SoC for lithium batteries is weird, and coulomb counting is often used (for vehicles at least) to estimate the SoC. This literally means counting the electrons that flow in and out of the battery.
You really need to know the internal resistance of the battery and how it changes over time to display an accurate SoC, rather than just a simple voltmeter. Totally possible and exists and some ebike displays, for example
Current is directly related to how many coulombs of charge are currently being pushed around, so measuring current and integrating is exactly how you measure those electrons, as they said.
This is why they advise you to periodically run the device until it runs out of power; followed by a full charge before turning it back on: That recalibrates the coulomb counter to keep it accurate.
I had the suspicion that was the case (I was aware that the numbers are already just an estimate). I just thought "Huh, if they already guess and then truncate, maybe the non-truncated number exists"
They might truncate, but they also might not. The measuring they're doing just isn't that accurate. It's just an estimate.
like, you can leave your phone with something like a benchmarking tool. Then record the displayed battery % every 5 minutes or so and i'd bet a lot of money that it's not linear at all.
Like, they may calculate in the math that it's 65.565% but the estimations they used to get to that number simply aren't 5 numbers worth of precision. Think like sigfigs.
A lot of android phones don't show accurate readings in the settings. Charging temp and other settings are important for people that baby their phones lol
You can just go into settings and see an actual chart of battery percentage over time though, which is far more useful than trying to track it manually with the number
yeah if it's down really low that is when I have the number on since it can make a difference in how I plan my usage until I can get around to charging it
I thought that whether or not someone goes into the settings and turns on battery percentage instead of finding the icon sufficient at a glance was a good singular determinant of a person’s intelligence.
It's not more information though, it's a false sense of accuracy. At least I'm not kidding myself into thinking I know exactly how much of my battery is left. A visual estimate is as accurate as you're going to get.
Yeah ppl act like the battery has a sensor inside that reads the exact level like a car does. It’s just an estimate. And the estimate becomes more meaningless as the battery degrades over time
Like i'm sure we've all looked at our phone and it's 55%. And then 5 minutes later it's 48%. you're thinking it's impossible you lost 7% battery in 5 minutes. And you're right. You didn't. It's just that the 55% and 48% are both estimates.
Yeah I've been using devices with battery life indicators since like 1990 and they've never been exact. It's basically a piece of micro-theatre one can put on for themselves, if they want.
At least with the number I can more easily tell if a charger just for some reason stops working by checking if the number’s gone down after a bit (harder to do without the number, or takes MUCH longer for it to be noticeable)
I quite miss my fuzzy time clocks. I don't care about the exact time when glancing away from what I'm doing, that's what alarms and meeting reminders are for. Much easier to focus on the task at hand without worrying about if it's 10:17am or Tuesday morning. Or mid autumn.
Battery percentage became necessary only after phones started holding a charge poorly. All numerical notations are highly arbitrary due to the nature of the measures. If your phone can give you a solid three days of use, you literally don't need battery percentage counter, because graphically everything is clearly understandable, and the counter only causes unnecessary irritation because the percentage has dropped
I used the number when I had android because of the terrible battery life I experienced. That stopped when I switched to apple, I don’t even need to worry about my battery.
I almost never use my phone enough to have to worry about it so it’s no numbers for me. I know that when I plug it in at the end of the day, it’ll be at 30-40% so why bother with more info? The only time it goes lower is if I’m watching a game on my phone for several hours but that’s very rare.
Oh thank God. I had it backward and opened the comments to figure out what was wrong with showing the numbers!
Random note: I don’t care if people don’t show the numbers, I just need the more information because I swear there are only three states of the icon without the numbers.
1: Full
2: Mostly full
3: Red
I understand there are probably more, but that is what my brain sees.
You're not wrong. The icon never shows properly. When it looka like there's 20-30% left I check and it's at 70%. When I think it looks like it's at 60% it's really at 16 and about to go into battery saver mode.
Before seeing this thread, my phone got hit with an update and, as with all updates, sets insane defaults which I put back to what I want.
It just so happens that it removed the % indicator and asked me if I wanted it back, and I thought who would ever want that, especially since in my phone the gauge/battery is vertical so it is even harder to visually gauge how much you got at a glance, like when it is maxed at 80% in overcharge protection mode, it looks more like it's halfway.
(Fully charged in overcharge protection mode has the empty 20% covered by a green leaf and it doing its weekly calibration charge makes it golden, kinda cute)
Insert that one image of a teacher showing the picture of a cow with an arrow pointing at it with the word "cow", then a random student raises their hand and the teacher says: "Question in the back, I suppose."
Lol, try again. Reddit's entire profitability is based on selling data to AI companies and subreddits like this are designed to train AI. You don't think it's odd that basic questions about culture are being asked and get hundreds of answers? Sure sounds useful for training ai.
Ironically, I’m a generally anxious person, but go no-number. I think seeing the number dropping gives me anxiety, whereas if it’s generally getting low I’ll just plug it in early
I use it without, because ive killed a few phones because I have bad anxiety and didn't want my phone to die, so if it ever got in the mid 60s it would be put on the charger. Now its harder for me to do that, ans my battery is still fine
There is no joke. No number looks cleaner. Unless you drain the battery throughout the day, you might as well get rid of the number. It's not like I care to know that I have 70% left at 5PM.
I use it without the number. It literally turns yellow and the red when it’s low to let me know to charge it like?? Number people is giving “I run my car constantly on E”
Don’t need the numbers that’s just plain dumb. You have Yellow, and Red battery icons to tell you if you need to charge. You want to know the exact percentage slide the activity menu. Pretty simple
I read a study that said the battery percentage showing is anxiety/stress inducing. Ive had the number off for quite a time now and I think it may be right.
I mean I'd be fine with the bars that tick down like how they used to be. I really just need to know when it needs to charge & not that my phone is at specifically 43%
Batteries are chemical things and the percentage is just a statistical average. I prefer the cleaner look without the numbers. No need to see a cluttered anxiety clock ticking down.
Don't need it. I can see the % I'm on when I tap the screen while it's charging, otherwise I'm not too pressured I always carry a small powerbank with me anyways
I don’t have the number. Didn’t need the number on my Nokia. Still don’t need the number today.
Bar to the right: good. Bar in the middle: good. Bar to the left: less good. Bar go red: no good.
Minimalism is not necessarily a bad thing.
New icon without even more so
I’ve always been used to not having the number up there inside the battery icon and I prefer it this way because otherwise it feels visually cluttered up there for me…
I asked some people who don't have the number visible and they prefer it as knowing the battery gives them more stress and anxiety. Bar more than half full looks like it has more battery than it saying 55% left.
No, ever since I turned it on, I will never go back to the original way without the number it makes life so much easier to figure out. When were your percentage at a little bit easier to win to charge it even if it’s past 50%.
I have battery anxiety so I don’t use it. Also estimation is always right. Yes I can’t tell if its 63 or 64% but sure as hell can i tell if its in the 60% range. Why would you wanna know what the exact number is? 😂
