    So, I jailbroke my iPhone 3G using Spirit, and it has the following things:
    Cydia, OpenSSH, SBSettings, MobileTerminal
    When I tested my battery life:
    SSH was off, 3G and Wifi were on.
    I kept track of battery life and time, and I'm wondering if this is normal for a jailbroken iPhone 3G 3.1.3.

    (Notes are included in attached image)

    Thanks.

    You left out a few factors:
    What signal strength was your 3G?
    How old is your iPhone 3G?
    Do you have email polling enabled and how often?
    How bright is your brightness setting set?

    All the above can affect your battery life. With that said, seems that after 14hrs+ you still have 44% of your battery which seems ok to me given what you have done, but can changed based on my questions above.

    It's exactly 1 year old,
    Signal strength is usually 3-4 bars,
    Perfect wifi signal
    Email and all push completely turned off
    Brightness is a little below halfway, auto brightness off.

    The battery can potentially deteriorate depending on how many charge cycles you've had in the past year, but the battery life so far sounds consistent with the information you have provided. :)

    Thanks. Although, since I gathered that data, it seems to be going a bit quicker now. I'd say on average about 1% every 5 minutes or so... bit worried.

    That doesn't sound right. Do you have email set up from an Exchange server? I had my work email set up on my phone and it was draining the battery like yours was. Instead of fooling around with the settings, I just removed the account and my battery life has been great ever since. If this isn't the case with you, the only thing I can reccomend is a restore.

    No email set up at all :( Really weird problem. If I restore and then jailbreak again, wouldn't I just have the same problem?

    How did you fix yours -- what did you find on Google?

    I didnt fix it. I just googled average 3GS life.
    Found some forums and saw people post basically what they lost throughout the day and what they did on their phone. Mine looked above average if anything.

    I would really suggest you put your brightness to about 1/3rd, you rejailbreak and reinstall everything you want, and you get mail sent to you like every hour.

    You most likely would not have the same problem, I dont know why but usually somethign will get emssed up or you will install somethign faulty. Id give it at least a try.

    Grab a thing in cydia called AptBackup. It basically creates a contact and stores everythign you downloaded off cydia I guess..

    There are also a couple tings out there that measure what is stressing your phone. I would try to find one of those and see where your problem is.

    Are you losing 1% every 5 minutes of standby time or 5 minutes of usage time? 1% every 5 minutes of usage would be about right, but for it to drain that fast while it's not in use is not right.

    I would restore the phone and set it up as a new phone. Give it a day or so like that and see how the battery life is. If it's good, then jailbreak it and see how that goes. If the battery is still the same, you should go to an Apple store.

    Just so you know, if you JB you will have reduced battery life.

    Really? Just from jailbreaking?

    FUD. None of my 5 iPhones ever had bad battery life. :)
