    I know this has been posted already, but people can't seem to find it so I thought I will put it up after typing it out for another thread. Doing this made a huge difference for me, your mileage may very.

    Here is what I did, and why for those who care.

    --- EDITED ---

    0. Make sure your phone is charged to 100%
    1. In ClockworkMod go to advanced, wipe battery stats (or, as of BB 0.6.2 you can go to settings, rom toolkit, troubleshoot, wipe battery stats - AKA PETE rocks and makes things easier)
    2. Use your phone till it dies (screen goes blank, ignore the battery percentages and low battery warning, if your stats were messed up you can run on "x" (5%) for awhile, I went about an hour on "x")
    3. Charge your phone 100%
    4. Your down. Don't run your phone dead more than once as it will not help (my understanding) and it isn't the best for the battery.

    --- EDITED ---

    The phone uses the stats to learn how much juice your battery can hold to show you percentages. When you wipe before flashing you reset those stats, and depending on how much battery you had left when you wiped and when/how you charge it right after that can pull those stats "smaller". By running the phone to true dead you get more accurate stats and therefore your phone will not tell you your battery is at 15% when it really is at 50%. So it looks like your battery life is better, when really you are just using "more" of battery (aka not charging your 50% full battery because the phone is complaining while thinking you are at 15%).

    When you do the battery wipe in CW, are you supposed to get a message that it completed it? I dont see anything confirming that it did. I simply select it and it goes back to the menu.

    So, this technically doesn't give you longer battery life? The display percentage will just behave more accurately?

    Or you can just go into Terminal Emulator and type:

    su
    rm /data/system/batterystats.bin

    Yes, Li-io batteries don't have memories so you don't 'train' the battery but you can train/calibrate the software which reads/translates the batteries status. Doing a complete discharge and full charge helps recalibrate the software (though you don't want to do it too often because full discharges can shorten the life of Li-io cells considerably if done to often.

    thanks, was looking for this, forgot it and seems I'm one of the few people still running SPRecovery.

    I found another way to completely drain battery quickly was leave the phone in recovery mode until it dies :)

    Just type the command and hit enter then exit. You could reboot if you wanted. If you really want to be efficient do this right after the battery has been fully charged.

    So wipe and then drain completely? I've always drained, charged to 100%, and then wiped the stats. Also, should you do this before installing a new rom each time? I've always wondered why i install one rom and i'm at 80%, flash a new rom and it drops to %30.

    Doesn't really matter. As long as soon after wiping you do a drain. The biggest thing is not to do 'too many' drains. Li-Io do NOT like being drained fully too often, it can actually shorten their cycle life. As per ROM I wouldn't do it every time you flash as this will result in too many deep cycles just do it whenever you think you're seeing poor battery life that you can't narrow down to ROM or kernel.

    Charge to full...with phone plugged in...wipe stats. You can do it in root explorer or terminal. I just use root explorer. As soon as I delete..unplug phone and use till it powers off. Then charge fully

    How so in RE? Would this be beneficial for my extended battery? If I reboot at 20%, its at 50% when it comes back on...?

    Is it really necessary to run the battery to 0% twice? I already did it once and wiped stats once it hit 100%.
