@rallewichs - Thanks for trying to help, it means alot. It looks like I still need to get a few more readings to really determine how long my battery life could be.
I guess this is the perks of buying a cheap tablet. My fire most of the time shuts itself down at 30% specially when I am running some apps plus wifi on plus the display brightness at half (the one with the half black half white shade circle thing). I went on a different route this time, I put the display brightness to the minimum and the main battery app was able to go down to 15% (double checked it with sim2k battery monitor, almost had the same numbers) which allowed me to get the notifications that the battery is nearly empty. This is also the first time that I was able to see red color inside the battery instead of the usual blue. Even if I opened wifi and some light apps (mail, facebook, etc) the tablet did not automatically turn itself off, which is curious because that is what it usually does at 30% and below. So I don't know, does the display brightness affect the tablet's reading of battery percentages or no?
Thanks for your positive feedback - I appreciate that as well!
Honestly, I cannot tell you too much about the route you have taken (I usually have wifi on and display brightness at 25%), but what I can say is that you are getting closer to your "best settings". My guess is: just a few more script/widget readings and setting experiments ... hang on!
I'm currently testing/comparing Tab_Gazer's recommendation. So far, I am not satisfied with the results (and the app itself appears rather suspicious to me).
And it might be quite interesting/helpful to know that I am running my flame with Ainol's ICS 4.0.4 without any custom ROMs. Just a few extra apps and that's it!
