Well, looking at several things on the chart has me concerned. First, you should never see those "cliffs", either at the down-side as in the first and second sections, or on the up-side as there is in that tiny spike to the right of the first section, and that huge vertical climb at the far right.
Now, let's talk about the usage profile. The phone signal (the bar immediately below the large chart), shows poor phone signal (yellow/brown) for almost the entire time during the first 1/3 of the chart. Then amazingly it jumps into the green for the entire middle third. Strangely enough, like clockwork it goes back to really poor for the last third. Is this a representation of where you were...perhaps home for a couple hours during part of the day, out for a couple hours, and back home for the next couple? I also see that charging took place for 3 stints, two in the middle timeframe and one long one during the last third. You obviously did this because it was reporting the battery as near depleted...I wonder just how depleted it really was - especially judging by both the huge drop-off at the end of the first third and also by that last massive G-force climb.
Next, the WIFI appears to be on all the time. That's not necessarily a bad thing, as WIFI is used not only for communication (when you have a nearby hotspot), but also for location data in cooperation with the GPS and Cellular towers, to pinpoint your location. Having WIFI on uses little power if not communicating, but also uses less power pound for pound than cellular for data commuications.
I see a couple long periods of awake, but one in particular where the phone was also with screen on. Were you watching a movie, or were you charging with the screen on constant? Having the screen set to never turn off while charging can have very strange effects on the meter's determination of the battery's State of Charge (SOC - or how much power is stored). I set the screen to timeout at 30 seconds and always leave the screen off when charging. The only time I set the screen to constant on is if I'm watching a movie.
What really concerns me is these apparent sheer cliffs. I'd like to see a more gradual and smooth transition from full charge to depleted or from discharging to charging, but that's not what I'm seeing.
I suggest you do the following at the next opportunity where you won't be needing the phone for a few hours...
1) Power the phone completely off.
2) Plug the charger in and allow it to "wake" into charging mode
3) Allow the phone to charge for at least 3.5 hours if it's an average sized battery, or 5.5 hours if it's a Droid Razr MAXX for instance.
4) Power the phone up and use normally for an entire day, avoiding charging in any manner for that timeframe, and use until it says you must charge it
5) Repeat steps 1-3, and then use the phone normally from there forward.
Once the above 2 full-charge cycles have been completed, and you've given it another day to settle in, post a screen shot again of the chart and let's see if it isn't better.
Good luck!
