I can't, for the life of me, understand why people are getting such purportedly poor battery life on jailbroken phones. I get great battery life, same as my stock 2.1, around 5+ hours of usage. I've also gone out for 15+ hours straight, using the phone during that time span only to make a few calls, a couple texts, some light email checking/web browsing and my battery didn't even move, even with all of the standby time. I'll post it again, this is what i have installed:
BossPrefs, Winterboard, openSSH, Cycorder, quake4iphone, psx4iphone, gpSPhone, MobileTerminal, and PdaNet, along side 3 home screens worth of AppStore/stock apps. Plus, iam running the "Bluebird" theme, AND i have 3G, Location Services and openSSH running AT ALL TIMES! I get no lag, no crashes, everything is normal. If i had a video camera i'd post a youtube vid up to show how smooth everything is...but i don't. Could Installer be the problem? It's about the only thing i can think of, seeing as how 99% of people who choose to jailbreak choose to have it installed alongside Cydia...but i left it out. Also, for my method of jailbreaking, i used QuickPwn on 2.1 firmware, i did not use pwnage and restore using a custom .ipsw.
The only other thing i could suggest would be that people claiming to have horrendous battery life run a test using 2.1 before, and after jailbreaking. Though people here seem to be complaining of faster battery usage after jailbreaking 2.1, there have also been many reports of STOCK, non-jailbroken 2.1 firmware making people's battery drain seemingly faster as well.
Perhaps someone out there could restore to fresh, stock firmware and turn autolock on to never, as well as whatever features they want, like 3G or Location Services, and let a movie run or let the ipod run till the battery nearly dies. Make sure you also have all the AppStore apps you'd normally have during this test. Note the usage time at the end.
Then, someone do the same thing using a phone with jailbroken 2.1 firmware running, and see how much of a difference there is in usage times. Do this with the same settings as above, and make sure you have all the Cydia apps and AppStore apps that you would want installed. Note the usage time at the end.
I'd be happy to do this test, but i am happy with my problem-free, jailbroken 2.1 phone and would really hate to restore...so if anyone wants to take a crack at it and debunk some possible myths here, it could help out a lot of people.
