    Since I recently found out a few culprits that were waking up my phone from sleep and they were not so obvious as to what they were here's a quick list of apps I have on the phone and it sleeps properly.

    48 hours after the last charge and I am at 65%! Overnight it drops by only 1-2%!

    The application that was waking my phone was TasKiller! I have since removed it.


    //////////// How to see if your phone is getting interupted from sleep ///////////////
    1. 1. Install spare parts
    2. 2. Turn the phone off
    3. 3. Turn the phone on
    4. 4. Wait for the phone to fully boot (do not kill any applications)
    5. 5. Lock the phone and wait 20 minutes
      1. 5.0 After you have waited 20 minutes unlock the phone
      2. 5.1 Go into spare parts
      3. 5.2 Click on "Battery history"
      4. 5.3 Click on "Running" and write down the time it spent without sleeping
      5. 5.4 Go to home screen and lock phone
      6. 5.5 Wait 20 minutes
      7. 5.6 Unlock and go back into spare parts
      8. 5.7 battery history
      9. 5.8 Click on Running and compare the current value with the previous! IT SHOULD NOT BE MUCH GREATER! For example: if it was 10 minutes before it should not be more than ~13 minutes after. If it is, you have something that is waking your phone from sleep!

    My config:

    Using Galaxo from forums (without the hero theme). DID A FACTORY RESET!

    Everything is on stock settings expect for these:

    ///////////////////////////Settings menu///////////////////////////////

    Thanks to kam187 and his thread on tweaks

    Copy paste from the thread!

    # Remount read/write
    adb remount

    # open shell
    adb shell

    # go to apps directory
    cd /data/app_s

    # delete QuickDroid (if you want to)
    rm QuickDroid.apk

    # delete NPS sync (it doesn't work so why run it!)
    rm wssyncmlnps.apk

    # disable drexe (this gets baseband info for NPS. Who needs it!)
    mv /system/bin/drexe /system/bin/

    # disable npsmobex (this handles auth with nps)
    mv /system/bin/npsmobex /system/bin/

    You sure seem to pack a lot of applications on your phone!

    RepliGo Reader,1.0.1 // uh, forgot what this is

    It's an excellent (perhaps the best?) reader for PDF and some
    other formats. How did you get it? Last time I looked only a paid
    version was avaliable, with paid apps not available in Slovenia.

    MarketEnabler enables paid market everywhere ;)

    Lep pozdrav iz Slovenije :p

    You need to run MarketEnabler everytime you boot up your phone. And it requires ROOT!

    Why is it that no good games seem to work on the galaxy - bloxx3d, space physics, speedforge. The moment it's not cartoon graphics the phone decides it's too complicated!

    tisti Well-Known Member

    It's a bug in the firmware. Samsung afaik shrunk the usable ram for the GPU.

    In the G8 firmware it was fine. Since then it is broken. Hopefully it will be fixed in the next Hdblog firmware release that drakaz is working on :) He is doing some crafty magic.

    I found that too. Were you using the widget? I believe it's that part of it that keeps waking the phone.

    I'm now using Advanced Task Manager, not free though.

    tisti Well-Known Member

    I was using it yea. Considering I have been using it for the last 30 days... I'd rather not keep it on my system at all. ;-;

    70 hours in and at 59% battery life. I love this phone now. All I need now is a multitouch enabled HTC keyboard. :D
  8. spottyelephant

    spottyelephant Well-Known Member

    Wow. Couple Q's:

    What firmware you on?
    What widgets are you running?
    What sort of daily use would you typically do?

    That's all the questions i have actually. Thought i'd more!
  9. tisti

    tisti Well-Known Member

    I'll add all that to the primary post then.

    I said I'm using Galaxo. :p

    -Its a custom build of II5 firmware.
    -I no longer have any widgets. Will be much more careful with them in the future.
    -A few calls daily, some wifi here and there, maybe some teetering.
  10. spottyelephant

    spottyelephant Well-Known Member

    Ah. Rite.

    - I'm too much of a ***** to attempt a custom Rom at the moment (especially since a lot of stuff doesnt even work with the official samsung firmware!)
    - I use widgets. (You wouldnt say "I have a boot in my car, but i dont use it cuz i don't want to use too much petrol"! Widgets are there to be used :)).
    - I would use my phone a lot more than that.

    So perhaps my battery is as muscley as yours after all. I just make it sweat a bit more!

    edit: those **'s represent another word for a cat!

    Eh, you have a nice FAQ about custom roms anyway. And if you do it on a laptop there is almost nothing that can go wrong anyhow.

    You can quickly check if your battery is draining properly with the first instructions in the OP. And if your battery drains more than a few % overnight while you do not use it, something is waking up your phone.

    spottyelephant Well-Known Member

    Ye that faq is excellent, I reckon on I'm gonna check ou galaxo rom.
    As for the widgets ull prolb dump twitter cuz to he honest I dont really use it!

    My phone sleeps fine, but I think I'm just a pretty heavy users :)

    Edit: did a lot of mistypes there!
  13. Xenon

    Xenon Well-Known Member

    No offense, but I tested battery life extensively on a system with almost
    no applications and widgets and 70 hours is just about the maximum.
    I find it hard to believe your 59% figure. I don't think it's realistic... possibly
    an error in the battery meter.
  14. tisti

    tisti Well-Known Member

    Non taken. I'm just trying to help out fellow galaxy users improve their battery life since I went from ~28 hours to 70+.
    Battery life can change with different firmwares. What version did you test it with?
    And more so, did you use the device at all while testing? Because I sure did use mine :)

    Current status:
    Battery level 17%
    Running for approximately 70+ hours.

    Had a bit of a music session :p Could also be that the battery meter is showing a proper percentage now.
    Will see what tomorrow will bring. If it stays above 10% when I wake up I'll be a happy camper. I'll also report on what time it shutdowns on me.

    What I've found is that with apn or background data disabled, your phone would use about 8% a day assuming you don't have calls or text.

    Somehow with the apn and background data enabled, the phone doesn't sleep as much since you can feel the battery is warmer.

    MichaelW Well-Known Member

    Well mine must be faulty too then. I had over 100 hours out of my phone last week and the battery was at 30% (I then charged it up over night as I knew I would be out all day the next day and didn't want to risk it running out).

    That was with one or two short calls a day, a few texts, downloading and trying out a few apps from the market, and even a bit of wifi usage too.

    Can you explain what these do please? I currently have:

    Compcache: On, disk size:25600
    Cpu sampling: Perf
    SSH server: off
    Renice: ON
    Provisionned: ON

  18. tisti

    tisti Well-Known Member

    Compcache - this creates a virtual compressed RAM swap partition. It takes programs in RAM, compresses them, and then stores them back into the RAM (that 25600 number tells the compcache to use 25MB of ram for itself!). I'd recommend you don't go above 12MB. Better yet, turn it off, phone is much less "laggy".
    Cpu sampling: - determines the clock speed of the CPU. I have mine set on Mix, haven't tested performance over the 3 settings though.
    SSH server - remote login over WIFI, leave on off unless you know what your doing
    Renice - sorts out service/application priorities, gives a nice boost. Leave On.
    Provisionned - this one I haven't checked.

    Ah the names make sense now. Think ill just copy ur setup tho!

    Mine barely makes it through 36 hours with very lite usage and no widgets running!

    Running the carriers baseband II1, I installed "Power Manager" to monitor the batter level, "Advanced Task Killer" -the free version- to kill ALL running apps, and "APNdroid" to even turn off 3G. I loose 15%-20% overnight!

    I noticed using the Task Killer an application called "Moxier Mail" provided with this ROM (actually it's a set of apps like contacts, mail, sync, calendar etc...) runs occasionally w/o being called! not sure if it cased this drain though.

    I got really interested in updating the firmware after reading your post, and after reading this post (
    My questions are:

    1. If I update the firmware and baseband and use a custom ROM like Galax0, would that improve my battery drain?
    2. If updated, would I loose applications provided by my carrier (i.e. GPS Navigator) for good or is there a way to back them up and install them on the new ROM?
    3. Would I be able to sim-free my device and use any carrier's sim card on it?
    4. Can I backup my factory ROM for recovery later on?

    I would also appreciate any help understanding what happens when you install the custom ROM (compared to a factory ROM or carrier's)...

    are you still using the pouch case
  22. hazboun

    hazboun Member

    I was just reading your post on a different thread about the case and camera button being yes i was using it till 5 min ago :D. Batter now is 59% and i'm going to test it overnight and hope it wont loose more than 1-2%

    In fact, you can hear the camera button being clicked if you slowly slide the phone into the case!
  23. Rastaman-FB

    Rastaman-FB Well-Known Member

    you will lose some over night but not nearly as much, it should still be alive in the morning

    i get 2 days out of mine with no background data and no auto sync
  24. hazboun

    hazboun Member

    Confirmed! last night I only lost 2% going from 59% to 57% over ~7hr with the same settings i had always :D

    I'm testing it today after a full charge and it's now at 99% after ~6hr with few calls and some GPS and WIFI. Still need to figure our this Moxier Mail that keeps running in the background for no reason...

    Rastaman: you are my man :cool:
  25. Rastaman-FB

    good news, amazing what that camera button does eh
