    @obsidian, Better Battery Stats says that it requires root, so I'm giving Battery Monitor Widget a try.
    @cr6, I'm also re-trying GSam
    Thanks for the input guys, however, even though both apps seem to give extremely detailed data, I'm not sure either that either is giving me (maybe I don't know how to read it) the simpler calculation that I'm wishing for.

    And maybe what im looking for isn't an available piece of info., which is the total power consumed over a given time, leaving percentage of battery charge left.
    Like this for a 3220mah battery:
    Total 1610ma drawn over 10 hrs, leaving 50% battery level, (my math is probably wrong here) which in my feeble mind..... if my battery has 50% at that point, it would say that the battery is performing as it should.
    Or, an app that could perform a 10 minute test, while putting a heavy load on the battery, showing if the battery is draining at the proper level.
    Then, if the test says the battery is good, I could look for a rogue app or whatever.

    Just make sure and use the GSam app for a couple days while using your device as normal, so as to get a good reading in case it is an app causing your battery drain.

    I will, but I'm not sure if the detail is there to show me good or bad battery health, but I'll keep looking.

    If it is an app, it WILL provide the detail. If it's not an app, it will also provide that detail. Which you can than use rule out, one way or the other, whether or not you need to purchase a new battery. Being that you can pick up an OEM replacement battery for less than 20 bucks, it won't be all that painful regardless.

    I have to admit, that because I did not know the correct terminology to use in this thread to explain what I was looking for, I may have been asking for help in obtaining the info, in a confusing way.
    I realized this morning, that what I am trying to get an answer to is whether my battery's "capacity" is anywhere near what it was when it was new.
    I don't see anything within GSAM that will show capacity.
    I do see that stat. is available in the 3C Battery Monitor Widget (it's not just a widget) (there is another brand with the same name also, that's why I specified 3C). Thanks for all of your input, and I'll report back after several charge/discharge cyles what this app reports my battery's capacity to be.

    As was previously explained, you're worrying about "voltage" & "capacity", and that really isn't your problem. Your issue is battery life. Battery "capacity" is the terminology used for the size of your battery, posted in "mAh". mAh stands for milli Ampere hour or milli Amp hour. It is a measure of a battery's energy storage capacity.
    If you're not experiencing the same "battery life" that you previously were, than you need to figure out what's draining your battery. It has nothing to do with "capacity" per se.

    Are you joking?

    Of course it has something to do with capacity.
    That should be the first thing that is ruled out.
    A battery with diminished capacity, will result in a shorter daily life, and IMHO, believe that is the first question that should be answered.

    I was never concerned about voltage. It was those spikey voltage drops as in the screen shot that I was asking if looked normal to anyone.
    You'd think I was turning on the flashlight or something, plus I don't know if those voltage drops would even be normal if turning the torch on.

    A battery has a limited amount of cycles. The only way a battery can lose what you are calling capacity is if it has been drained too far or overcharged. That being said the life of a battery diminishes a little after each charge cycle. Lipo's have fixed a lot of this but batteries won't last forever.

    I personally believe those spikes are being caused by the cpu. It's just a matter of finding why. That's why I suggested Watch Dog. Android being #1 battery user is also another clue to me
    The screen isn't showing as a top user so I don't think it's the brightness but a screen set to fully bright could show up like that as well. Yes using your flash as a torch would show spikes I would think, though not as dramatic.
    I'll keep checking on this thread. It's got me intrigued as to what is going on.

    Yeah, I believe so also. I haven't determined for sure yet if this battery is in good shape, but so far it's looking like it is ok.
    Right now I'm at 39% after just under 7 hrs..
    GSAM says that of the 61% used, that the screen is responsible for a little over a third of the use (35%), and today I have had the screen on more than usual.
    GSam also reports that 55% of the 61% used is due to apps

    And it also shows Android as the biggest offender.
    Multiple FDR's and cache clears have made no improvment.
    I even did one FDR last year and loaded no apps for a while. Just used stock everything for several days, but that didn't help either.

    Also, I did use Watch Dog last year, but all I remember was that it gave me many alerts of high useage, but it didn't solve anything.
    I don't know if there is a solution to this dilemma, but simply wanted to make sure that in my frustration of such poor battery life, I wasn't overlooking the possibility of it actually being a battery problem.
