Honestly though, the big thing about this battery for me now is that I know that it's virtually impossible for me to kill it in a day.
This weekend I tested out c:geo and went geocaching with it. With GPS running for over 2 hours (which includes the c:gro program, GPS, AND display) in addition to over 3-4 hours or regular display/program usage in addition to that, I still was only at 3650mv by the time I went to bed. Personally, I can't imagine me using it more than that in a single day, and I still would have had plenty of usage remaining at that point.
It sounds like your pulling on it pretty hard..... if you aggressively pull a load on the battery, when you hit 3700mv the battery isn't near as drained as if you do it gradually.
In other words.. it will bounce back better because you artificially have the voltage pulled low due to the heavy use.
An extreme example is when you crank a car battery the voltage plummets during the high amperage crank, only to recover when the load is removed.
At any rate..... I reached 78 hours of use this time before my Seidio extended battery went dead!
I had wifi and bluetooth on the whole time but no gps.
I used my phone only occasionally when I really needed and didnt' do any "on purpose" heavy browsing etc but to check the market freqently, weather, and use of my "documents to go".
For what its worth, I used to use ATK and I felt my droid ran smoother without it... now I do use "task manager" by rhythm software.... it seems to do great and works better than ATK IMO.
This was my second drain since calibration and now it reads 60:15 for expected battery life with moderate accuracy still, I'm sure that will change soon. I expect the expected battery life will go up.
One thing I noticed is I think "preinvent" changed the algorithms a bit to monitor and play off the mv readings which I like.
Last night when I was up to about 74 hours of use, the battery left app still showed about 4 hours of time left even though I was 15 hours overtime from what it originally thought my battery life would be. Seems I remember the mv reading at that time was around 3580mv or so... maybe a tad less.
I'm sure I wouldnt have got that much more time If I had changed the game plan and started heavy use..... but I bet the expected time till dead would have changed too as the mv reading dropped.
The numbers used to go negative when you went over your expected time.. that doesn't happen any more.
Seems the "battery till dead" time must be playing off the mv readings is my guess as they were pretty spot on for accuracy.
I do appreciate the effort to develop an app that allows accurate monitoring of the Seidio battery.
I'm sure its been hard to do without an extended battery to play with.
