Ok, so like I said I was doing some discharging and such relevant to this thread, I didn't get any diag. stats for your Entropy but I just wanted to show this is it's most exaggerated and plain to see form. There are 3 pics here...

Pic 1, this was an overnight drain with the phone not being touched *AT ALL* Not even to check the time.



Pic 2, this was a drain using the fabled "pull out your battery because it's magic!" method.



Pic 3, this pic is showing the DRASTIC difference in battery life since using Entropy's root method (2c in creepycrawly's sticky) this is showing the battery after I had just done a data wipe (to fix WiFi problem after root) and yes the battery drained from ~50% to ~20% in just over an hour and a half, but the screen was on 97% of that time, and I was downloading/resetting all my apps and widgets and such. Also, since I'm now rooted, I have the thrill of using TiBu to freeze TetheringManager and DRM Content.

Take note of how Android OS is at 4% battery life as opposed to 70-95%.



Edit: I was also playing music the entire time I was restoring app settings and redownloading/installing them.

I am charging my phone right now and going to do a normal discharge of it to see change in battery life just to be 100% sure that it's back to normal (I'm currently 99% sure because when I stopped using the phone, I reset the clocks on CPUSpy and checked back after about 45minutes, the 200MHz bar was very small, Deep Sleep was almost full).

I will throw that pic up on this post after I have the results.

The one I am puzzled about and have spent a bit of time researching is the sec-battery-monitor. From what I read that is the Android built in battery monitor. Why in the world would that thing have that high of a wakelock count? Is that a bug? I have tried several ROMs at KH7 and KK6 and both bases show the sec-battery-monitor high wakelock. Maybe when I fix my data problem this one will go away, but after reading for hours trying to see if anybody knows why this wakelock is there, I have not read a root cause explanation that makes sense (most people conclude an OS bug).
It polls periodically doing work - it seems to sometimes wake the device but not always (considering the polling interval is 10 seconds), but will usually go and do its thing if something else wakes up the device. I've never seen it consider an unreasonable amount of time either.

Just an update about my last thread, I'm currently at 6 hours off battery so far, battery still at 91%, so that's about 1.5% drain per hour. I have used it a tiny bit also, and yes WiFi and the cell radio have been on the whole time. Right now Android OS is sitting at 46% battery life which is reasonable on the current usage, I know that it's not running away with my battery anymore because Android System is right behind it at 24% and then Cell standby at 12% after that. CPU spy timers are 15 min in 200MHz, 5 hours 39 min in deep sleep, and that's out of 6:09:21 total.

If somebody would like me to post the screencap I have of it, just let me know, otherwise I'm going to just be lazy and not upload it.


The reason I am posting all of this info is for the other people out there lurking (I know there are some) who are trying to decide whether or not to make the jump into rooting for the sake of getting their battery life back. It seems scary if you've never done it before, but now that I have, I'm not sure why it ever was. Anyway, very simple steps here.

1. Go to this thread: here.

2. If you're on 2.3.6 (which I'm assuming you are if you received the OTA update that murdered batt. life) Use method 2c (titled: 2c.) How to root by flashing Entropy512's Return/Unbrick to Stock, Kernel + Rooted System Package with Modem using Odin3 One-Click Downloader)

Before doing step 3 I advise that you download Titanium Backup, go into the Backup/restore tab, hit menu button on your phone, click Batch, and select Backup all user apps + system data.


Note: You will have to redo all your widgets and such manually using this method. So I'd suggest taking a few screen shots of what each of your homescreens look like.

3. After you are rooted (all steps on how to use that method are included in that thread) you will most likely not be able to activate your WiFi. Simple solution, go to Settings>Privacy>Factory data reset. You do ****NOT**** need to format USB storage for this to work. So leave that checkbox UNchecked.

4. Boot your phone up and do all the intro steps to get back to your freshly wiped device. Confirm that your WiFi is working. Is it working? Yes? Good. Now go back into the market and redownload Titanium Backup.

!!!!!!!!!!!Do NOT do a full batch restore with TiBu as it will rebreak your WiFi!!!!!!!!!!!


5. Go to the Backup/restore tab in TiBu, go find all the apps that you actually want back, and click "Restore" and it will ask you if you want to restore the app, the data, or both. Do this until you have all your apps back.

Hopefully this will give a few of you that are still on the fence the courage to join the wonderful world of rooting. My next step will be finding out more info on the topic of Kernels and ROMs.

Do you have to install superuser &/or busybox after rooting with that method?

I dont think you need to install either after rooting.

SuperUser is automatically installed when you root using most methods, if not all. This method automatically installs it.



Update. Currently at 18h 8m 49s on battery. 68% battery remaining. Exactly how my phone SHOULD be when I'm not using it.


Update 2. Got to 1d 3h 51m and had 14% battery life left, I actually played some games and such, had around 2.5-3 hours of screen on time. I just plugged it in because I don't feel like having a near-dead battery all day tomorrow :lol:


Update 3. (For those wondering, I'm updating the same post over and over to avoid bumping this and making it appear on people's list again... It is mostly for people looking for info who come upon this thread after the fact).

Well it's been about 2-3 days since I rooted, charging my battery is basically optional every night. I'm consistently getting well over 20 hours with my normal usage. For me normal use would be maybe 10-30 minutes of browsing via Dolphin browser, maybe 100-150 texts using Handcent, 200-500 texts via Heywire, maybe 10-30 minutes of games, a couple hours of listening to music with PowerAmp, 2 email accounts, 1 updating every hour, the other updating every 4 hours. A weather widget that updates every hour, WiFi always on, even when not in use. Facebook notifications refresh interval 1 hour. Screen on auto-adjust brightness with 30 second screen timeout.

If there are any other new users out there or anybody else that would like to ask me a question or point something out to me, I will gladly give/take any advice available.

I have read this whole thread. Phew. I had an I777 that I put CM7 on. Went all the way to nightly 22 or something. I think at this point, I was trying different modems from this thread. I moved up to UKK6. Then I got tired of the volume adjustment issues and wanted to try the Car Dock and Home Dock and MHL adapters. So I had to move off of CM7. I moved to UnNamed 2.2.1. I flashed that back in December or something, without ever changing the baseband. I have had pretty awful battery for months and never really cared to find out why. In my opinion, this stuff should just work. Now, I'm starting to change my tune. I need to make it work. Anyway, my question is, Entropy keeps talking about XWKL1 baseband. Is that only available on the I9100 (which would make it useless for I777 correct?)?

I never said anything about XWKL1 baseband... I9100 basebands will never work on I777. I777 system firmware bases will with porting efforts.

Baseband is the modem to handle cellular traffic. I think that most everybody will tell you that this is not what is causing significant battery issues.

What Entropy is talking about is the Gingerbread base. i9100 phones have the base for the ROM XWKL1 (among others). Using the Hellraised process allows us to use these ROMs on i777 phones. You might want to try UnNamed 1.3.2 first or just make sure you try a XWKL1 based ROM that has been Hellraised.

That is my fault. I didn't realize you were referring to the ROM only and not the modem firmware.
