    I bought an extended battery on ebay and I want to test how much mah it actually has. Is there an app that tests battery capacity specifically the mah? It wouldn't be that hard for an app to test. Just monitor how much gets used and how much gets put back into the battery. If there isn't an app is there another way I can test the capacity of this battery? I have a lipo battery charger if that could work.

    No man sad to say there is not such thing as app that will test mah because its not an actual number just a possible capacity. I wondered the same thing i bought one off ebay from China for my vibrant what a rip off. there is NO possible way to add 300mah with out changing the size or else it could be dangerous. so i would stick with OEM battery or buy a brand newnOEM it should cost about 25-30 dollars for one but its worth it.

    By the way first charge should be over night, than drain the battery completely 3 time and fully charge. that way full capacity imprint will be made. lithium batteries leave an acid imprint on battery that will shorten the capacity is not recharged from 0-100%.

    hope this help.

    This is totally false information about discharging a battery. You don't fully discharge lithium ion batteries. If this is true then you would need to do the same thing with laptop computer batteries since they are lithium ion batteries as well.

    Agreed. Totally false information. There's no shortage of it on the net about li-ion batteries.

    Yup. The battery is actually never allowed to fully discharge to prevent you from damaging a cell. There is no such thing "battery memory" anymore. Li-Ion and NiMH are the same way in that respect. NiCad, if used at a constant pace and discharged to the same level, over and over, could give a false energy drop. The thing is, you don't use a phone like that..

    “Battery Test” App into Android Market:

    “Battery Test” is android app to test any android based samrtphone, tablet battery.

    It will generated an ExcellSheet and a Doc showing whole LOG of battery and it’s uses.
    It will have following BATTERY information.

    Time, Level(%), status, health, voltage, temperature, technology etc.

    It is highly customizable and next version has plan of getting a very good user interface,
    where user can see live battery info on the screen then just on log.

    For more details go to following URL:

    I discovered PowerTutor recently. It is a great little app which gives you a great analytical tool. You can start it and stop it anytime. You can check out power (mwatts) or energy usage (Joules) for last minute, hour or day for every app that is running on your phone. You can separate out the LCD and CPU usage. Contrary to my initial belief, it appears you can disable any usage information from being sent to the Developers by disabling it in options.

    I like to compare two or three similar apps and see which one burns more battery. As long as they have the same functions and features, I will dump the ones which burn more battery.

    Regarding running down a Lithium battery, my understanding is that there is no memory issues with Li-Ion batteries like with the old NiCad batteries. However, running down an Li-Ion battery is often recommended to make sure that its calibration is accurate.

    There's also Battery Monitor Widget; it measures mAh, at least on devices that support current measurement. On others, it estimates the mAh value. I've been using it on my SGS2 for quite some time, and it appears to be reasonably accurate considering that the device apparently doesn't support direct measurement of its current draw.

    But isn't Sedio still recommending discharging extended capacity batteries that they sell 3x, running them down and recharging? Why?

    An app can't just "look" at a battery and instantly know its capacity. The only way that an app could possibly determine the capacity of a battery would be to measure the amperage used as you ran your phone from fully charged to completely discharged. I imagine just about any battery monitoring app could tell you that. I use GSam.
