    I just received my father's 9900, he got a note 2 so yeah!

    The battery life on this is horrible I have heard that going on a particular OS rev can help like .394 or something.

    Currently the phone is on : 7.1.0.523

    please help, Battery saving mode is set to always on.

    What do you call horrible? If you don't use wifi you can disable the radio along with bluetooth. Depending how heavily the phone was used before you got it the battery could be on it's way out. From all the charging cycles..

    Your current OS is well out of date.

    Try the latest release .825 which is stickied at the top of the forum.

    Would also advise doing a wipe before install
    BlackBerry 302: A complete wipe and clean install of your BlackBerry OS | CrackBerry.com

    Also after loading new OS install any apps fresh from App World rather than backing up and restoring.

    This should improve things for you. Also if you do a search of the forum you will find many threads with battery saving tips.

    If your Father has had the 9900 for some time it could also be time to consider a new battery, you can pick up genuine JM1's very cheaply on Amazon

    Legal Eagle linked a tutorial for installing a new OS, just read it. The download sources of the .825 firmware is stickied on this forum.

    Just for your interest: I have used .523 for quite some time and it was one of the first OSs with better battery life. Things again got better with .569, however using .714 and now .742 for weeks I can't say battery life improved much compared to .569. So you shouldn't expect any miracles migrating to a new OS here.

    You can use any carriers OS on any phone provided you delete the Vendor.xml file(s)
    If you read the .825 thread there is a tutorial post by Elite1 in there quite early on telling you how to find these files.
    Found it for you, it is post number 16.

    There are multiple advantages in using a hybrid. However, just by judging you obviously don't have any experience in device wiping and OS installation at all, you shouldn't be thinking about that hybrids right now. Start off with upgrading an official firmware build, which actually is quite easy. Once you got that and you know what steps to do, you might think about installing a hybrid.

    The Vendor ID and splashscreen remain unchanged no matter what OS you use.

    Whatever the phone shows now will not change no matter what OS you install.

    the 9900/9930 comes with a 1200mah battery....don't expect to get super long life out of it...if you can get a full day out of a charge you are doing well....

    There are battery apps like tinymeter and meterberry (not available anymore) that track battery drain percentages.
