What stages does the status bar battery indicator show?

I unplugged my Captivate around 7:00 AM when I left for work, used it on wifi during the day, wifi at home, etc. When I was getting ready for bed I noticed that my battery indicator still appeared to look like I had 2/3 life left. I was stunned, a day of use and I still have 2/3? No way. I installed a battery widget and guess what: 39% battery. Under half yet the indicator in the top-right still showed ~2/3?
So I am curious, is the indicator at the top only a 3rd based indicator? (something like: 3/3 100%, 2/3 from 30-70%, 1/3 from 0-30%? Or does the indicator at the top display more precision than that? I just don't get why the indicator showed well over 50% when I was actually 11% under 50%.

I read that its very inaccurate, so i'm not sure exactly what values it is set to display. I would use that battery widget for a better gauge

I dont think its that accurate either. I used mine a lot yesterday and it showed like 3/4 or 5/6 of the battery still left, then I looked in settings and saw it was around 50%.
The battery icon in the upper right corner is basically worthless. I've posted several times somebody should write a small app that gets rid of the icon with just a number there that tells the percentage. Newer iphones have this option, either a battery icon or the actual percentage.

I would much prefer that. I'm not even asking for exact precision, but the indicator is just way too far off and I don't get why that is the case. The indicator should read current battery levels and display the proper image, simple as that.

I can confirm that my indicator is way off as well.

I just downloaded battery indicator which puts another battery icon with percentage on the left side of the taskbar. Just gotta deal with having two battery icons for now.

Yes, I saw that there are several of those apps in the marketplace. I was hoping to avoid having to have two battery gauges. Maybe nobody cares, but with a rooted phone it shouldnt be too hard to create a new battery gauge icon (of course I'm no programmer so what do i know)

I think the battery icon is only showing 4 or 5 stages of battery life, and it's very underhanded because it shows more than what it actually has.
a full battery is > 75%
slight sliver is 74% - 50%
orange is 49% - 25%
red is < 25%
I would love to have the icon replaced with something more accurate.

[Q] Charging and battery indicator

Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?

This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better

I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?

Tablet battery not charging to 100%

I have a TF300 with the keyboard dock and it probably spends most of it's time with the keyboard.
Now when I charge the battery it will only charge to 70% and refuses to go any higher (even the lightning bolt on the battery disappears)
The light on top of the tablet stays orange and never turns green.
I've tried to full drain the battery twice now but no luck. I've also been keeping it apart from the keyboard dock to stop it from trying to charge.
I've attached a screenshot of my battery graph to show you. I have rebooted my device several times but this doesn't show on the graph.

[Q] grey battery icon on boot

Device:
VZW Blue SGS3 32GB, original battery
The issue:
This only happens when the device turns itself off due to low battery. When I try to turn on the phone it shows am empty battery icon (i.e., no green or red) with a huge grey recycle type symbol in the center of the battery (a circular grey version of the green recycle symbol, with two half circles instead of three corners of a triangle). This image flashes on screen for maybe 3 seconds and then immediately powers off.
At this point the phone doesn't respond to normal reboot measures (hold power button, hold power + volume, etc). The only way to get the phone to respond is to re-seat the battery. Then, when you plug the power cord in, it will vibrate once then show the battery icon again and turn off.
At some random point in time the phone "revives" itself. Here's where the fun begins. When it "revives" itself (can be anywhere from 10 mins to 10 hours later) the battery looks like it was charging the entire time (i.e., after 2 hours it has a 40% charge)! One time when it revived it was fully charged!
Background:
This happens on the stock ROM as well as Slim Bean (2.6 & 2.7). That's half the reason I went with Slim Bean...exceptional battery life. And, it has worked, as it's only happened twice since switching to Slim Bean. It was happening once a week with the stock ROM because the battery would frequently go below 15% without my knowledge. Now, sure, I can control this by making sure the battery never gets down to 15%. However, a $600 device shouldn't lock up just because the battery gets low!
I did call VZW about this and they were pretty much clueless. They didn't seem to be familiar with that symbol. Their only suggestion was a new battery. I will take them up on the offer, just to get a free battery, but I really don't think it's the battery. If it was the battery then you would imagine this should happen randomly and not just when the battery was low. To me it sounds like the battery charge/protection circuit flaking out. Here's the real thing to consider to discount the battery: the grey icon remains even when the battery itself is at 100%.
Has anyone else seen this problem? I'm at a loss because I can't even google for it...the search terms are too common. So if anyone knows a specific name for this problem, do share!

Lol, same exact thing that is happening to my phone. Ive learned to deal with it because my phone has physical damage was tl buy a stronger charger or keep the one I already had and not let the phone die. The things you described is 100% my phone lol.

Z3 Battery Madness (1%/50%/100% Cycling constantly)

My battery life keeps bouncing between 1%, 50% and 100% and doesn't show anything else, you can be looking at the screen and you randomly see it flick between all three values and even more weird, the battery menu is no longer listed in the settings menu and I have no way of knowing what amount of charge my battery actually has.
This morning the phone went off saying low battery (whilst also saying 100%) and when I turn it back on it shows the low battery symbol in the centre of the screen and does not boot-up, great, the battery must be dead. I put the charger in and the red LED light comes on and battery low indicator come on for two seconds, then switch off and endless repeats no matter what I do..
I left it for an hour doing that and turned it on and used the phone for 30 minutes without any problem, then it turned itself off saying low battery, and started doing another loop of the low battery and red light in standby mode round and round again even though it wasn't plugged into anything. I pressed the reset button and after that I couldn't turn on as just a standard, battery low message.
I did a repair of the phone, which surprisingly was able to be carried out despite the fact that the phone wouldn't turn on because of "low battery" before I did it (which makes me doubt it is low) and the moment I turned the phone on after the repair it was still "Low Battery" and refused to turn on, which is somewhat strange bearing in mind it clearly had enough battery for a repair.
I left it for 4 hours charging and I turned the phone on and it operated for an hour in a factory reset mode no problem, however the indicator cycling was still going on. I plugged the charger in and the sound for charging was made, but the phone showed as not charging, despite the fact it made the sound that it is (I think it is actually charging but nothing to indicate ti is)
Again I go into settings and there is no battery menu there, if I search for it using the hourglass it tells me no battery data is avaliable. I search for Stamina mode and put it in Stamina mode and it refuses because just when I hit it, the battery reader says 1% and it says battery is too low. With some good timing I manage to press Stamina mode when it was on 100% and now it's in Stamina mode with 942 hours remaining,, the phone has been on for 3 hours now and now says 950 hours remaining.
Meanwhile the battery gauge continues to cycle 1%/50%/100% all of the time.
Has anyone seen this before?

I did not have this exact same issue, but Battery menu disappeared and battery would mostly show 50% (and very rarely the real data).
Got my battery exchanged now, everything back to normal now. Might be Sony used crappy batteries (though as long as they don't explode I'm somewhat happy).

I sent it back to Sony and I am now am about to go into a third week with no phone.
For the last week they have been waiting for stock to exchange the phone, since they have no stock (no joke) I am still waiting and they cannot tell me when they will get stock.
The fact a mobile phone company have no stock of phones, is pretty funny.
