I used the saurom 1-click to upgrade my i897 captivate. I charged it all night and the battery meter never went above 53%. Yet there was a notification telling me the battery was fully charged and to unplug the charger.
Why doesn't the battery meter rise to full? How do I fix this problem? Is there a way to recalibrate the meter?
Thanks,
Vipe
I downloaded a battery callibrate app and thought that would fix the problem.
I was sure the phone was fully charged, although the meter says 53%. I used the program to calibrate the battery. I expected the meter to jump to 100%, but that is not what happened. It stayed at 53%. I charged all night again, but it never went above 53%.
Do I have to let the phone totally die first before performing the calibration with the app? How do I get the battery meter to go to 100%?
Thanks,
Viper

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?
Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?
Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.
Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.
same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.
Speedmod K13C and Serendipity 5.12 on my i896
So, whenever I wake up in the morning, my battery is at 94%. Occasionally it might be a little lower, but mostly low 90's. So last night I turned the phone off and left it plugged in for 12 hours and the phone read 100% in charge mode (for lack of a better term). When I booted into Android, it says the phone was charging at 94%, but the battery icon in the top left said the phone was charged, and when I unplugged the cable, I only managed 94% on my battery.
I tried plugging the phone back in for 30 minutes, then wiping the battery stats, but this did no good either.
Any suggestions?
This is a known issue. Mine only goes to 98% after unplugging. As long as you can make it through the day don't worry about it! There really isn't a"fix"for it.

Run your battery dead, charge it up all the way to 100% with it ON, I guarantee it will go no lower than 96% when you unplug(whether u wipe battery stats or not)

its a feature of Lion battery used in our phones actually...
but this can also happen if u flash ur rom without battery fully charged...not a bug...at all
Hey all,
I have had terrible misfortune in the realm of battery stats. Ever since CM7 (and maybe even before) my phone is unable to figure out how much battery is left. Here is a common scenario:
Charge phone overnight, use phone throughout day, battery dies after 6-7 hours of moderate-heavy usage. I plug it in, reboot, and then it reports ~60% battery left.
Another common scenario is that it will dwindle around 5% battery or less and go up and down until it finally dies.
I know that this is a misreading of the battery and not battery drain or a rogue app because when I flash a new ROM the battery life is amazing for 1 day. The day after I flashed Team Hacksung's ICS rom, I got almost 17 hours of battery life with 2.75 hours of the display being on and 30 minutes of Google Music. I was blown away! But even then it was dwindling around 5% not knowing when it would actually run out. The day after, it was back to its old tricks of misreporting the battery percentage.
Today I charged it to 100%, unplugged it, and shut it off. Then I plugged it in while it was off and let it charge to 100% again and wiped battery stats in Clockwork mod. I'm getting ok-ish battery with that, but it's not even close to how good it was when I first flashed ICS.
Anyone have any ideas what I could try?
Thanks!
When you wiped the battery stats did you let the battery fully discharge and shut off before charging again?
After wiping battery stats it is recommended to let the phone fully discharge to the point where it will automatically shut off.
Keep in mind with the age of our phones, it could just mean your battery is dying. Try the above method, but in my experience uncalibrated battery only last a few days. The phone will "fix" it by itself the longer you use it.

That's what I'm doing currently. Battery life seems improved, but we'll see what happens. It's nearing death now, ~6%. At this point it will probably misreport it for a few hours until it finally dies. I left it unplugged overnight, so now it's at 19.5 hours uptime with 1.75 hours display time.
Definitely improving! I hope that it successfully recalibrates.
Battery stats have nothing to do with how the os calculates remaining battery...they are what is displayed in settings>about phone> battery use and are reset each time you charge to full.
You're just giving it a good bump charge...wiping the stats is just a placebo effect.

Seriously? Wow I didn't know that. Is there a way to actually reset how the OS calculates the battery?
Does this app do anything?
https://market.android.com/details?...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
Nope...that app is just perpetuating the myth of what the batterystats.bin file does.
Don't hate me for this but, Then how come Roms usually give me better battery life after a full cycle? not bump charging or deleting battery.bin just running it?
Because the system for tracking the remaining power is getting to know your battery. once it gets a feel for it, it's more accurate. In theory anyway
So the "give it a day" is still true, at least in theory?
Sure

battery gauge temporarily fixed by removal and replacement of battery
Ever since I rooted my phone, I've noticed that the battery gauge/meter is way off. I keep an eye on the charging voltage and try to pull the plug around 3.92 volts. Problem is, the gauge is always reading low until I pull the battery, wait a few minutes, and then reinsert and boot up. Then it's fine for a while, but I notice it creeping down even though I keep topping it off with a charge to keep it around 3.92 volts.
What's going on? Do I have to fully deplete the battery and charge to full to have an accurate (or somewhat accurate) battery gauge? Do I have a bad battery (this battery has been used only a couple months)? Is something else going on here? Recommendations, studacris? Doesn't the os use battery voltage to calculate state of charge (%)?

Please post all questions in the Q&A section, this is for development only.
Hello, I'm encountering a weird issue with my phone.
It seems to be happening when I don't fully charge the phone, even though it's kinda random.
The issue is that the battery is draining damn fast after charging the phone. The first screenshot shows how I lost ⅓ of my battery in 14 hours without having touched the phone. There's a difference between the beginning curve and the ending curve, that's because I tried to reboot my phone.
I do have AccuBattery installed, which is an awesome app. And it actually shows me than during this interval, I lost around 600mAh (see second screenshot). That should represent 15%, which would be a good value because I'm usually losing around 1% per hour. I shouldn't have lost so much battery.
So.. it seems that the battery is not being charged at 99% at all? I think my battery level has some issues. Because when charging, it usually stays at 100% for around 20 minutes, but is still charging according to AccuBatrery. This can be noticed on normal charges (third screenshot).
If a charge from 19 to 100% charged about 3300mAh and a charge from 7% to 100% charged about 3620mAh, my last charge from 10% to 99% shouldn't charge only 3400 mAh. And that's related to my problem of "phone is still charging even at 100%".
I already tried to empty my battery and fully charge it, I already tried to wipe cache, the issue is still coming back.
Is anyone else encountering this issue? What should in order to fix that?
Thanks in advance!
Bumping. Any idea? :/
Here is another screenshot showing the battery is being discharged with ~2000mAh
