So I used to go all day using my phone with about 4 hours talk time and 1-2 hours screen on time, checking emails excessively using Yahoo mail app, download apps here and there, facebook checking etc and have about 15-20% by 8pm (wake up at 7).
That's been changing a lot lately, even before the ICS update...it was getting miserable actually. I suspect it could have been a miscalibrated battery meter, so I did that and no luck. When I heard about the .215 leak, I decided to go for ICS. I cleared cache, didnt Factory Reset though, then updated. Then I cleared cache 2 more times, and my first day was terrible - and the thing died at about 40%. So I did 2 days of battery recalibrating and downloaded Juice Defender.
Since then, it's been okay...but nothing to write home about. Sync has always been off, the data network is not on Global but CDMA.LTE now, screen brightness at a minimum, no push notificatios, wifi only on if/when I use it, Yahoo mail app for email checking, Google Maps for quick Nav trips (I tried Mapquest and cant stand it...their version of Google Places sucks and I use that a lot) and that's about it.
Yesterday I downloaded Advanced Task Killer to try to help out with many hanging processes...but it didnt help or hurt any
Attached are the screenshots...let me know what else I can tell you. I am unsure what to do next other than factory reset :-(
Total time on Battery 9 Hours 39 Mins, Screen On 2 hr 36 mins & 53% of battery drain, Talk Time 2 Hours 41 Minutes. Remaining Battery 15% and draining quickly at 11%/Hour
