Recent battery drain?

[denisew1972]

I have noticed a significant battery drain on my EVO since the new OTA came out last week. I am wondering if this is simply coincidence (it is an old phone after all) or if this is due to something running in the background from the new update. All was fine last week, downloaded the update and bam.... I unplugged my charger this morning after an all night charge and 19 min and 30 sec later I'm at 87%?? All I did was check Facebook....

PS - I had the extended charger almost the entire life of the phone... it started going bad on me a couple months ago and I switched back to the original battery at that time. So techically my battery is almost new.
