[Nexus One Android Development] Docmjldds:
Never saw any difference in subjective feelings of laggs or smoothness with or without animations. Same for Quadrant scores. Objectively, Kernel and how much over-clock and governor made the biggest difference in quadrant scores. The method of install makes a huge difference IMHO. Not only the partition schemes, but actually formatting them prior to installing. I not only use the modified format utility I posted that formats system, data, and cache, along with running the wipes using Amon 2.2.1, but I also either boot to my Pqmagic disk and format the EXT4 partitions, or use the mini partition tool to do the same. Every little bit of "clean" helps wrt installing and getting least amount of issues. Once in a while, I will see a string of FC's occuring for no reason, and if so, I basically wipe cache files and reflash on top to take care of this. Only has happened twice since using either Rod's data2EXT or the data2sd scripting I happen to prefer, when altering stock MIUI setups that come with a2sd already as part of the ROM, or when using any CM7 based ROM such as a nightly, or Fitsnugly, or Evolov as examples that work quite well with the faq I posted and data2sd.

Just my 2c. What works for some doesn't work for all.

And to add to the mix since this used to bother me a lot...my phone used to basically die off at 15% battery. Various Roms and kernels over the last 1 1/2 years would yield everything from terrific battery times to absolutely horrible.

Discovered this utility a few days ago that basically calibrates our Nexus Ones to use 100% battery instead of 94% use approx and the 15% issue. It's critical to follow the FAQ in how to use this app. You will NOT regret using this. Major difference for me in battery times, compared to what I used to get. I won't bother giving exact numbers since the way i use my phone is not going to be the same as anyone else. Best to run this for yourself and see what a difference there is when your battery is calibrated correctly. This app and method ONLY works on the Nexus One, which it was written and designed for.

<<Copy paste from the Sense Rom thread here on XDA:

The thread involved questions as to why some posted great battery times with a rom and others posted horrible with same rom<<<Just background to understand:

<<This is like comparing apples and oranges. So many different factors. I would first start with the requirement that anyone posting battery times be required to run the excellent battery calibrator app and faq posted here on XDA. That way, you are getting a full charge on the battery to begin with as well as it being correctly calibrated to not shutdown at 15%. I ran this yesterday and what a major difference in what I see.

Plus the battey app can be downloaded from the market as well. Author is Jon Richards and it's specifically for the Nexus One. Battery Calibrator v1.30

See HOW-TO in post 3 below, or in-thread post from mtw4991, for instructions on using app to calibrateIt's a must read>>

Sorry for the long post. Since we are all patiently waiting for Rod, this will be a good homework assignment for some that are interested in gaining substantial increase in battery efficiency on the N1.
