Ok...a couple days in now on version .570. After the clean install process...battery life seems to be on par with what we've grown to expect from RIM devices.
The only residual bug I experience is an occasional lag when entering text. This lag appears across all platforms where one may enter text...email, texts, IM, BBM, web pages, etc. I never had this issue before on any build so I have to assume it is native to V .570. Still not yet annoying enough to compel a downgrade for me.
OK...hope that helps someone out there! Thanks again for all the feedback.
I have read about that lag time with this OS more than once in different forums so I agree that it seems to be native to the v570.
Alright, 24 hours now on the clean install .570 and without charging still 65% battery left
I had my Wifi enabled most of the day on purpose, and also Whatsapp and MSN. Normally I close these when not using to save battery.
Thanks wilsonjs for the information about the clean install, I am going to use this method in the future too.
