    I hope to get a better test tonight and will report back.

    So after successfully calibrate did the age change?

    I can't say if it properly calibrated or not because of all the shutdowns in trying to get it plugged in before shutdown.

    I have an extension cord stretched to my computer from where I usually charge my phone (so I can listen to stuff as I fal asleep). I hope tonight will be a better test.

    I'm sorry that I don't have much to report today...

    So what do you think did the trick to the full charge?
    Was it the setting age to 100% or the disable_overcharge?
    I really don't think that the disable_overcharge will help at all.
    At least in my case (cheap 2300mAh battery posing as a 1150mAh one), the disable-overcharge option did work because even after changing the registers it wouldn't go far. Seems as if the Pre is really thinking that the battery is a 600mAh one instead of 2300.

    Curiously, after disabling overcharge protection, it did fully charge and got calibrated.

    After that it has been smooth

    So, for high cap batteries, change the registers, disable overcharge protection to let the battery do its job, calibrate using your script (discharge to less than 3.4v, charge to 4.2), reenable overcharge protection and you're set.

    The only remaining thing should be to look why the kernel sees the batt as a 600mAh one instead of the real value, patch the source accordingly and see if it displays the real value. Although I guess it will have no effect whatsoever on the duration.

    Again, somline, thanks for your research!

    Is yours reporting the full amount, or just 2400mAh like mine?

    It was only reporting 2400mAh when I first installed it. I've since changed the registers so it reports 2800 and have been going through charge/discharge/calibration cycles with it.

    Its a big battery. Takes a *long* time to discharge it even with the screen on.

    Overclock to 800Mhz (it's quite safe), turn on mobile hotspot (or mytether Wireless), and go play some PDK games (I love NFS to drain my batt).
    To be on the safe side have a fan nearby

    This way you can drain your battery pretty fast!!

    800Mhz? Been running that kernel for a long time.

    I dont think PDK games are possible on a Verizon 1.4.1.1 phone...

    Mainly I just have been leaving the screen on, and cranking the brightness.

    You can get some of the older PDK games (EA, Glu, Ubisoft), and play

    Stream something to your Pre, you get the idea, keep it busy.

    I think I have found one problem with not be able to run my script because the pre shutsdown before be able to connect charger.
    It's the UVF the undervolt flag.
    To proof that:
    People with that problem can you please post (or pm me) the 3' value of first line from dumpreg (it's the status register):
    Code:
    cd /sys/dev*/w1*/32-*
    cat dumpreg
    00: 0f 03 00 81 00 88 12 13 f5 9f 1f a0 5c 20 f8 0a
    10: 02 c7 d0 f0 80 80 7f ee 01 be 00 7e ff ff ff 00

    My dumpreg:
    00: 4f 07 00 71 00 .....
    Pre switches off exactly at 3.4 Volts. Script alert and broadcast message at the same time..
    Std. battery, 1150 mAh, Age: 96%

    Does "cat status" do the same thing? Mine says:

    "power-on-reset, undervoltage, charge-termination."

    Recharge it just to boot, unplug charger, run script. I had to do this 4 or 5 times.

    Good Luck

    I'm at 75%. Bought my Pre on launch day June 2009.

    Where do you guys buy new batteries from?
  16.    #356  
    Thanks for the "under_voltage" information. Yes cat status gives you (hopefully) the same in readable text. To easy for us ;-).
    EDIT: And like Seidio said: "The palm my read it wrong". That's the reason we read it direct from the battery ,

    Thats what I've assumed. You all have that problem.
    I cleared the untervoltage flag (UVF) and run a complete discharge charge circle and it seemed to have repaired the 20drop0 "sudden death" problem.
    So who wants to try:

    Code:
    cd /sys/dev*/w1*/32*
    echo 0x01fb > setreg
    More info about the UVF in the manual.
    As you can read, after clearing it you should do some full charge discharge circles.

    If this works I will include it in my upcoming app "Dr. Battery" ;-).

    Please post your results.

    Do we do 0x01fb THEN do 0x1480? Or do we ONLY do 0x01fb?

    I've echoed 0x01fb so far. I've been using my Pre like crazy all day the past couple days and have decided to plug it in whenever I got back to my desk Just In Case(tm), so I haven't gotten down too low for a few days, but I should be able to run it down tonight (~6:00pm here at the time of this typing).

    I drained my battery down and it still did the Death Drop at ~18%. I only had less than 2 seconds to get it plugged in. Needless to say it shutdown...

    I guess I'll try yet again tomorrow...

    Thanks Somline! It took some hunting (I'm not very savvy at this stuff yet), but I finally figured out my battery is at 95% of original capacity. Pretty good considering I've had it for two years now.
    And thanks also to you puzzlegal, your tip got me to where I needed.

    You guys ROCK!
