Is there an app to show Battery Current Drain/Charge?

    I have been searching and just can't find a way to show the amount of current draw/charge on the battery (in milliamp hours).

    On windows mobile we could see this and in light of the Moment's battery issues it would be a great way to see what is really going on.

    Any ideas?

    Try a app called Battery Graph, I beleive you're looking for something like that.

    I tried Battery Graph. It shows the percentage of drop over time but it does not show the current draw in real time.

    For example, on Windows Mobile we had apps that could display the exact current draw (ie 57mah) and it would fluctuate depending on what the device was doing.

    I suppose what you're (we're) looking for is something like ChaDis (which I've mentioned earlier)?

    You could try Battery Dog: It graphs battery percentage, voltage, temperature, and "hourly percentile change" which is sort of like "battery drain". However, I've found it quite slow to plot the chart, and its service seems to be not always running.

    I don't think any of the android phones actually have a way to measure wattage/amperage -- in fact, I believe that Android only supports percentage, voltage, and temperature monitoring -- so apps must calculate it from battery drain.

    Battery life shows how many mV are left mine curently has 3800mV not sure if that is what you want.

    Thanks but, no.

    I am looking for a measurement of "current" which is in amps/hr and will show as units of "mah". Your suggestion shows voltage, which shows in units of "mV".

    I have been searching for an app like this with no luck. If Android currently does not support this function, how can we ask for that enhancement in future versions? This was something I used frequently on my WinMo phone so I could see how the things I was doing would affect battery drain. Seeing the actual charge rate was also quite useful for testing/benchmarking different chargers to see what worked best.

    been looking for this as well, without luck. somebody mentioned there actually is a source for this info in proc directory, but I don't know much else

    I've been looking for this too. The closet I've found is osmonitor. Filter the system logs for 'current' and check back every few minutes.

    It's in /sys/class/power_supply/battery/current_now and it's in 1000x mA.

    Someone actually has made a widget ! [IDEA] Power Draw Widget - xda-developers

    It doesn't report pure realtime, but with some 20-30 seconds delay. Perfect anyway !!

    The app is "Current Widget" ... at least that will give you the incoming current. I used it to compare the current that a portable battery was giving versus having it plugged in to household AC power

    Does anyone know wheter the amperage reading shows some kind of a difference, for instance during charging does the amperage reading is the difference between current consumption and charge? if so this makes sense, if not my household charger does not deliver 1000ma as indicated.

    thanks in advance..

    I could not get anything at all to show up on the Current Widget. Is it because I am rooted? Still on stock rom and kernel. Do I need a different rom or kernel?

    Quoted from this app's description:
    "Many chargers pump in more current into devices than they should"

    Has the author of this description any knowledge of batteries and their chargers? ;)
