Is their an App that shows current battery usage?

I remember back in my windows mobile days someone had an app that would tell you your current mah you where drawing is their anything like that for android/our phones?

you might look into Spare Parts, System Monitor or Juice Plotter

Battery Problem?

I have the Sedio 3500 mAh extended battery. It was not as good as i expected and can barely make it through the day. Last week i installed battery monitior and various other similar apps. I am now running Incredibly ReEnginered and I have also used ReEngineered Z and Skyraiders 3.5. My system is reading that i have 10% left but i still have 3.687 Volts. Is that correct? I use battery monitior in my notification bar and it says based on voltage i should have 48% left. Is there anything i can do to sync this up or is this normal?
Thanks in advance

Correct way to charge and use SBC kernels?

I was wondering if someone could explain the correct way to charge kernels with SBC? I have been using the Tiamat 3.3.7 kernel with CM7 and Salvage-Mod and gotten great battery life but that was using it with a extended battery as of late I have been using my Standard Battery with Sense and CM7 using a SBC kernel on both and noticed that it rapidly plummets to the mid 80s in about a half hour of music play. What I was wondering is do SBC kernels not work with stock batteries and what would be the correct method to getting a full 100% charge? Any help would be greatly appreciated.

Even with skepticism (INFO), I prefer SBC and have been for a while now.
This is what works for me...try at your own risk!
With battery monitor widget (from market) menu > settings > monitoring preference > hit monitor without widget, history update rate- 1min, battery capacity (whichever size you using).
charge...
Now, at times could never to get it to this point like it states here. So what I do is when the light turns green (it isn't fully charged), from monitor hit history, you'll see positive mA's getting smaller and smaller, when it hits zero unplug. (I usually hit calibrate [app from market] at this point if its a new ROM, kernel or battery). Should be good to go. I get it sitting on 100% with a 3500 mA for 3-12 hrs depending on use.
I can't keep track of the charge like that on a non SBC kernel.

Yep, the green light and the "100%" are meaningless. But the charge milliamps will not hit zero, at least not with my extended battery. They drop to 6-8 milliamps and that is drop dead full charge idle power.

Extended Battery Charge Reporting Sucks

I charged my Samsung extended battery to full then reset the battery stats but my battery reporting is still terrible after 3 days. As soon as I unplug it from the charger it is automatically at 98% and drops quite rapidly.(~3% every 5 minutes of active use)
Would allowing the battery discharge to automatic shutoff alleviate this problem? That hasn't happened naturally yet

That can be normal behaviour. Mine does it sometimes too. 95% and up on any phone will be that accurate. As for your drainage problems, your phine is doing something heavy duty in the background. And/or you are running full brightness. I am getting 4.5 screen time on average. I was able to get over 5 hours this weekend. For me to get 3% every five minutes i have to be playing a game or been downloading a large file over cellular data.

Seems like you either have a bad device or you have an app or two that is killing you. Something that gets push notifications for example, like a messenger or something similar

I have been experiencing this as well, my stock 1850mA battery seems to outlast my extended 2100mA battery by about 20%. Has anyone else seen this behavior? I have been thinking that maybe I got a bad battery.

I have just installed Battery Monitor Widget as recommended in a battery related thread in this forum, and it is showing my extended battery as having 1750mAH. I don't know why and I'm not sure what to do to fix it, and my battery life is pretty awful.

Battery Monitor Widget allows you to manually change the battery capacity.
Touch the gear symbol, select ""Monitoring", then "Battery capacity". Enter 2100 if you have the CDMA extended battery.

Yes, I saw this - but if it's getting the capacity from the phone, and the phone is reporting 1750, isn't something wrong? Doesn't that mean it will stop charging the phone prematurely because it thinks it is at max capacity?
In fact, I just remembered the stock battery is 1850 mAH so I have no idea where the 1750 is coming from...
Thanks for your reply.

its coming from the GSM version because it has a 1750 mAh battery.
battery monitor widget is not pulling from the chip inside the battery, it is just guessing your capacity because it knows its a galaxy nexus. hence you have to manually enter your correct capacity into battery monitor widget yourself.
also remember this fuel gauge is not capable of giving current readings. so battery monitor widget is guesstimating current based on extrapolating the drop in your percentage among other tricks the developer uses.

Thank you very much for your reply. It makes sense what you're saying, I took the setting in BMW literally as it states:
"Override capacity provided by phone"
Thanks to both of you for the help. Now I still need to find out why my battery life is sooooo bad...

from a terminal, you can dump system power statistics.

the mLocks at the very bottom should be 0, meaning nothing is preventing your phone from entering deep sleep.

[Q] Two batteries - configure capacity in android ?

I just got one of these extended 3600mAh batteries for my i927, and now i wonder if there is any way to tell the phone/android when/if i am swapping batteries and therefore changing capacity of the battery.
So far, the only thing i found was a way in CWM to reset the battery stats. I now try to train the phone to the new 3600mAh battery, but if i ever should even just temporarily swap it against the older 1800mAh battery, then the stats will get totally screwed up again, right ?
So, any app to maybe store and recall the battery stats ? Then it would be possible to train the phone independendly for each battery, store the stats, and accordingly use the app to recall the battery stats after swapping it.
Thanks

It's not the phone that gets trained, but an IC in the battery itself. Each battery has an embedded processor that tracks current charge levels using a semi-predictive algorithm. That's what the third conductor is for -- it's a one-wire serial connection between the phone and the IC inside the battery. So when you switch batteries, you're also switching the IC that's tracking the battery's charge.
The batterystats.bin on the phone is just statistics tracking for what is using power, how much, and how often. These are the stats you see in Settings -> Battery and have nothing to do with current charge levels, actual or displayed.
tl;dr: It doesn't work that way. Swap your batteries freely and don't worry about it.

Brightness taking the battery?
Is there an app or tweak that will let me turn down the "ambience" on my captivate? I mean, on my old iPod (I know, right ) there was a Cydia app that allowed me to set a certain time for when the brightness would kind of "lower the hue" and made it look kinda like a old style fleurescent light. Kind of amber in color.
In my battery manager, the screen takes up MORE than 50% of my battery life, and I was wondering if there was a way to do that, instead of having to manually turn up the brightness when I need to. It's currently all the way down, and yet STILL ueses a bunch of battery.
Anyone?

I use the Lux app from the app store and it does this. At a certain time it will transition to a warmer color that you set and it also has many settings for light dimming based on a number of factors. You can also set the output to sub zero.
