Although I have some exotic cats that I know you guys would do a double take if I posted their pics....I will stay relatively on topic here during these slower times when so many of Typhoon's rom's features are working!!! ;)

Does last app open before screen off and lock use battery or cause significant drain in standby?

So...does the last app open before you go into standby...cause any drain during standby? This is a variation of battery saving questions that I really have not focused on nor have I seen or read much about. You see, I use Widget Locker for my lock screen...and upon unlocking, it is set to go to my home screen. So when I unlock my screen, I never see the last app I had opened. So what I am saying...is that I completely forgot or have been ignoring the possibility of that last app causing any drain or funky wake lock....or partial wake lock. So I think the question is an extremely valid and interesting one!!!

Doing a few quick tests with a few games, and some of MY core apps like Handcent messaging, Browser etc., I believe most apps go into a dormant or frozen stage similar to exiting an app with the home button....where the app is still in memory but has not been fully terminated. ***I just ran Angry Birds, shut off my screen with Stock Lock Screen, then measured drain for a few minutes, and then unlocked. Angry birds was there and the sound started immediately apon unlocking but the drain in that short period of standby was mostly normal (2-5ma over 5 minute period of testing) There were some small spike but that may or may not be Angry Birds. (Maybe angry cats!) I am going to guess that there probably will be the odd app that does not take kindly to being left open just prior to turning your screen off and locking,...but most apps will behave. ***NOTE: that obviously, GPS apps will likely stay alive in standby especially these types of apps which run SERVICES and in many cases, show an ICON in the Notification bar.

It would be good to get USER feedback on the above.

With this rom, typically, games and apps will eventually get kicked out of memory (excuse this simplistic description) when they have not been used for a period of time. (eg 10-20min) or if enough other apps have been opened, the earlier apps (eg Angry Birds) will give way to the new ones. Even if ...eg Handcent is ON according to your Task Manager, it won't open INSTANTANEOUSLY after 10-20min of none use...where as if you open it twice or more in a short period (eg 5min) the 2nd and successive openings will be super quick. (Dorimanx's rom, on the other hand, is managed manually or by user settings with Task Killers...instead of the OS handling it....correct me if I am wrong) Some apps, like Facebook, seem to respawn into memory no matter how they are killed. Dev Zeppelin talks about BULLET PROOFING apps. He is successful with the Homescreen not getting killed EVER by the OS. I have that tweak implimented. But bulletproofing other apps (eg the DIALER) would be fantastic but the OS keeps killing it. Maybe not in Dorimanx's rom. Lots of detailed info about this at Zeppelin's V6 Super Charger thread...http://xdaforums.com/showthread.php?t=991276&page=454)

(if anyone cares to correct or update any of this info, I would be happy to edit it.)
