I was on .232 and upgraded to OTA version mainly to be on upgrade path. Clear improvement in my book. Had some issues that made me decide to factory reset and I'd say it was even noticeably better.
I read .232 has some debugging code running which probably results in done negatives though I don't know what, really.
As far as battery, I ran GSAM (still do, since it doesn't seem to have any negative effects) and found a few apps that excessively woke device when to me there was no need, etc.
Facebook ate battery and had slot of activity despite me turning off notifications so I disabled it. Big difference. My battery, which is an extended and always got me through the day and into the evening, now lasts 16+ hours with heavier than moderate use.
I don't remember the other apps I installed or disabled over time, but GSAM battery monitor is a must now for me. Misbehaving or poorly written apps standout now. Also shows data and cpu use. Now the high data and battery apps that I have I have because they're worth it to me.
