To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.
[Verizon Droid Charge] Cilraaz:
I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.
[Verizon Droid Charge] shrike1978:
I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.
[Verizon Droid Charge] Cilraaz:
Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.
[Verizon Droid Charge] buhohitr:
I confirm what shrike1978 said is correct. The 13 steps wipe and bump charge are nothing but waist of time. I doesn't do anything for the battery. When you unplug, the battery stats reset by the OS anyway. In order to achieve more battery life, you have to see what consumed your battery power and is the phone in deep sleep while the screen if off. You could use one of a good app from the market to help out and keep them in control.

It's reduce your screen brightness, throttle your cpu, disabled all the un nessesary service like gps/4g while phone is sleeping. I have tested with SetCPU and basically, if you set setCPU OC to 1200 for example, most of the time it throttle between 400-800 (to save power,but keep your phone snappy, if your phone is at 100, it took a bit to ramp up to 800, in this period you will see lag). So you could use setCPU for undervolt only (specially for the 400-800 freq). Your goal is no lag and save a lot of battery power. Law of physic, faster car, wasting more gas.
[Verizon Droid Charge] ewh1292:
I agree. I only tried calibrating the battery once when I flashed Eclipse v1.2. Needless to say bump charging is very relentless and I'll probably never do it again.
[Verizon Droid Charge] JihadSquad:
Calibrating the battery is bull****. I flash roms at 30-40% battery (for some reason new versions are released at night) no calibration and get 15-20 hours normal usage.

[Verizon Droid Charge] Cilraaz:
Your image is quite telling, actually. Your phone only did anything for 40 minutes out of 11 hours and 5 minutes. It doesn't really matter what battery saving measures you use if your phone isn't actually being used.

In my attached image, the phone has been collecting data for 24 hours and 39 minutes (I reset it when I loaded CPU Spy yesterday). My phone was in an active state for all but 9 hours and 4 minutes. I would guess that this is mainly because I have multiple IMAP accounts set to push and listen to audio most of the day at work, which I found to mainly use the 100MHz or 200MHz profile when the screen is off. I also bowled last night, and I track my stats frame-by-frame with an app called Strike Out Stats, so that's another 3 hours of usage.

I haven't done a 100%->0% test recently, but I tend to get 8-10 hours when using my phone for audio. That doesn't matter too much anyway, since I have a charger at work. Over the weekends, I use my phone considerably less and usually get 16-20 hours.

Sorry about the dark image. I forgot to remove Screen Filter before taking the screenshot. I haven't noticed much difference in battery life with Battery Saver, and the new version with the two icons (neither of which can be properly removed) which is completely annoying. CPU Spy is pretty nice, though, since the data is displayed better than in SetCPU.
[Verizon Droid Charge] buhohitr:
You didn't enable CPU throttling in the settings, once enabled it only use 400-800 frequency. You need to stop/start the app to take the change. Again, this app only help people with poor battery due to extra processes etc.. If you already have good battery life, there is nothing more to save, make sense?
[Verizon Droid Charge] Cilraaz:
Control CPU Frequency is enabled and set to auto. The app was restarted when I upgraded it today. However, if it were to limit my phone to 800MHz, I'd remove the app instantly. For as little as the phone goes to its top speed profile, I'd rather it actually have the ability to do so when needed.
[Verizon Droid Charge] buhohitr:
If you read my earlier post, race car consumed more gas (law of physic). So by limiting the frequency between certain range, you still get snappy/smoothy phone without sacrifice the battery (this called balance between power and battery saving). Of course you always can override the limit and run at max speed at any time, but don't complains about saving battery.
[Verizon Droid Charge] Cilraaz:
You seem to have missed one of my bigger points to push the whole CPU frequency thing. To run with your (albeit flawed) car analogy: a parked car uses less gas than a moving car. If you only have your phone doing anything for 40 minutes out of 11 hours, you're not going to use much battery and there's not much room to save battery either.

Also, I never complained about my battery life. Whenever someone suggests something to save battery life, I'll try it. However, this Battery Saver app didn't do any of the things it supposedly should do. It didn't change my screen brightness (Screen Filter was disabled for all but the 15 minute period before my previous screenshot was taken) or throttle my CPU, so I was curious what benefit it was supposed to provide.

In the course of the conversation, I noted the large difference in phone usage times between your screenshot and mine, so I pointed it out. None of my comments were meant to be offensive, if they've come across that way. I was only continuing the battery life portion of the conversation.
[Verizon Droid Charge] buhohitr:
There many ways you can look at battery saving, I will give you a few to look at them.

1. Battery drain when phone is not in used (park car)

2. Battery drain when screen on and 4G are on (actively looking at Facebook or browse internet).

3. Talking on the phone - SCREEN IS OFF, 4G is off.

With frequency throttle between 400-800 (most of the time we're on these frequency), which leave us un noticeable slowness, but save battery by using a lot lower voltage.

Yes a park car, do contribute a lot to battery saving (sleep mode). If you are using your phone in the morning for 1 hrs at 8am then again at 6pm, the sleep time in between is very important, because while it's sleeping, if it only drain 1% for 4 hrs vs 1% per hrs. By 6pm you don't have much left to use, make sense?

Now for battery saving while using your phone, screen brightness, 4g, and cpu voltage and how frequently you open an app or browse different websites do make a big different on battery saving. For example, If I open a webpage and read one article for 15 min is using less power than if within that 15 min, I search for different sites or open photo and video from a site.

Now if you phone already has all the "proper battery saving" setup you WILL NOT see any improvement, because there's NOTHING THERE that the app can save, make sense?

I only recommended this app to people who experiencing poor battery life and have very little or no technical knowledge on "how to". It's a simple way to save battery power for an very average user.
[Verizon Droid Charge] shrike1978:
The whole analogy seems a bit flawed. To use it a bit better, Android in general runs more like a car with a variable displacement engine...when it's idling, it's using lower clock speeds (fewer cylinders), and when it's at load, it's using higher clock speeds (more cylinders). Limiting to 400-800MHz is like running a Cadillac V16, but reprogramming the ECU so that the engine can only run on 8 or 12 cylinders. No matter what it does, it can never drop to 4 cylinders or go up to all 16. Even when going to 4 cylinders (100-200Mhz) is completely sufficient for performance and would save gas (battery), you won't let it, and when going to 16 cylinders (1000+MHz) could allow you to accelerate more quickly (process outstanding jobs more quickly), it isn't allowed.

A CPU governor that properly implements profiles (smartassV2/interactiveX/ondemandX) manages this type of thing just fine. They keep the CPU slower when your screen is off, and lets it get higher when the screen is running. You're letting the CPU use its full range and you aren't artificially limiting yourself to a narrow band.

My CPU runs at 100MHz and 800MHz more than any other frequencies. It gets all the way up to 1300MHz when needed, and it hits all of the frequencies in between. smartassV2 is doing it's job, and it's doing it well, without having to clip its wings.
[Verizon Droid Charge] buhohitr:
I was thinking like yours, but maybe some of kernel developers can chime in, 100 actually using more battery than 200 and 400 is not much more than 200 but provide a faster turn around ended up saving more battery. I'm not the expert, just my observation for the software. It actually done more than just controlled the cpu. You can look at the init.d and see there are about 5 files in there that manage a lot of things from cpu, memory management etc...Also it might cap @ 400, but it may also used 100 during sleeping, but since 100 is considered useless for anything, so CPUspy failed to report(can cpuspy works with 100?)? I don't know. BTW, if you take a look at Galaxy Nexus formum, the min freq is 350 for battery saving, not 100.
[Verizon Droid Charge] buhohitr:
How about this one? still have almost 40% left. My other cpu image only intended to show that the app is throttle the cpu.
[Verizon Droid Charge] Cilraaz:
I was going to drop the whole discussion, but...

Considering 88% of your battery usage was between screen, cell standby, and phone idle, I'd again say that your extreme battery life is a complete lack of usage. "Use your phone less" isn't a valid answer to the question of how to save battery. I don't pay a few hundred dollars to have a useless piece of plastic hanging from my hip. If I were going to do that, I might as well get a featureless flip phone.

Frankly, I'm sure I could downclock my CPU to 400MHz max, charge it up, leave it off all day (except, apparently, for a short phone call), and see 24 hours or more of battery life.

Again, nowhere have I complained about my battery life. I have a charger nearby at least 80% of the time. I saw a tip on saving battery and figured I'd try it (and asked a question in the process). After that, I simply noticed and mentioned the lack of usage in your previous (and now this) screenshot as a likely reason for why your battery life is so good.
[Verizon Droid Charge] buhohitr:
I have a very open mind, in my case the app did help a lot and I would like to share with ppl here. However, it didn't help you at all, so be it. I only get 4-10 hrs max out of my battery. After I installed the app, I reached the 20hrs mark easily. Again, this is my case only and it may work for some but not all. I'm here to learn, so if you don't mind can you post your screen shot where your phone display is greater than 50%? since display is the most battery killer. Thanks.
[Verizon Droid Charge] Cilraaz:
I'm not quite certain how this is relevant. Yes, display is the biggest battery killer, however you again missed my point or are avoiding it. Both screenshots that you've posted show awesome battery life, but almost zero usage. That's not a real-world scenario for most people using smartphones.

My battery life is not as good as yours, and I've never claimed it to be. Then again, I have 9 IMAP email accounts using push via K-9 Mail, TweetDeck checking Twitter/Facebook every 15 minutes, and I'm testing Alphascope (a TweetDeck competitor) with it checking hourly.

Again, my only two points in this thread have been: 1, originally asking what Battery Saver did, since it changed nothing on my phone and 2, pointing out that your screenshots of awesome battery life also had almost no usage in case I was missing something very obvious. I'm really not trying to get into a pissing match about anything here.
[Verizon Droid Charge] buhohitr:
Hey bro, we're never will in the pissing match. We're here to learn, enjoy and have fun with our toy. I just show you my usage, yours maybe totally different, but based on what you said, there is nothing out there can keep up. For example, I have 4 IMAP accounts (you have 9), we both have facebook,twitter etc.. but I set them not to sync. I manually sync them as needed. Maybe it's better that you keep an extra battery on the side or change the way you setup your phone. :-))
[Verizon Droid Charge] Cilraaz:
I may have misread your posts, then. Tone is most difficult to inflect over written word.

Are your 4 IMAP accounts set to push, poll, or manual like your Facebook and Twitter? I've noticed that in my case, K-9 is always fairly high on battery usage and up there in wakelocks. I'm pretty sure that's mainly due to the constant connection to the IMAP server.

[edit: In any case, I've pulled this thread way too far from the OP's intent. My apologies, donkason.]
[Verizon Droid Charge] buhohitr:
None taken, all my IMAP accounts, facebook, etc.. they all set to manual. For Facebook when you launch the app it auto update anyway, for IMAP, I click on the first one then hit refresh, go to second hit refresh and so on. All can be done and in sync in about 30-45 sec. My screen setting is 20% but I'm using the dark android wall paper so every icons are bright and sharp, you couldn't tell that I'm in the low screen mode. I removed SDM, disabled google service. I uninstalled Facebook and use browser to access instead (FB is running as a service and it used up a good amount of battery). I also notice that it took like 15min for the phone to go into deep sleep mode. So make into a habit NOT to turn the screen on very 5/10 min (many ppl have this habit, by doing this the phone will never go into deep sleep). I also program to keep screen off when receive messages. I also turn off vibration (use sound only). By doing all the above plus the battery saver app, now I can achieve 20+hrs with my "regular" usage. In your case, if you decided to keep your setup/habit, just get another 3-1800mah batteries and a wall charger from Ebay for $20. It only take 15 sec to swap out the battery. Well worth it if you outside your home a lot. Good luck.
[Verizon Droid Charge] donkason:
Well, I have google services unchecked, downloaded battery saver just now, and have been monitoring my battery usage with betterbatterysaver. Dolphin Mini is still chewing up most of my battery, but that makes sense because I use it the most. Mediaserver is a close second and I have know idea what that is. For wakelocks I don't see anything out of the ordinary. Paondora, mixzing, etc.

Another issue, when my I use flash with my camera it freezes my phone up every 2nd or 3rd time. I have to pull the battery. It did it today, I pulled the battery, and went from 83% charge down to 63%. I would do a screen shot of my stats but that feature doesn't work either.
[Verizon Droid Charge] buhohitr:
What level you set at (there're 3, 1 is the least saving and 3 is the most)? let it run for 24hrs. Don't keep checking your phone every 5 min. It took 15min to go into deep sleep. Also, go into menu-->settings and put a check to "cpu control". reboot your phone. Let the phone sleep over night without plug in your charger, to see how many percent drop over night during sleeping. Tomorrow, only turn your phone on when you need to use it, (don't turn on every 5 min). Also download CPUspy to monitor your CPU. Good luck.
[Verizon Droid Charge] donkason:
Had to to go back to stock. phone was booting itself up after being turned off. it would sit for 5 minutes and magically start up. Something catastropic was wrong.

will wipe, root, and flash again and see what the battery does overnight. thanks for the feedback. thats a good way to control variables and get to the "root" of the problem......yeah, i just went there with a stupid joke.
[Verizon Droid Charge] buhohitr:
You have a chance to go back to stock, let try this out, It save even more on battery. Load Tweakstock 1.4 with Tweakstock kernel and the battery saver app. Must run for 2 days to see full saving. Make sure to check option "control CPU". I decided not to play with Overclock/Undervolt any more. I'm runing Tweakstock kernel and it's trouble free. Good luck.
[Verizon Droid Charge] donkason:
I've pinned it down. It is my data connection, regardless of the reception being good or bad it drains my battery horribly. If I put it on airplane mode it sips at 1%2% per hour like it used to.

I've done some digging for a fix but I can't find anything definitive. Is there a work around for this? I really hate to keep my phone on airplane mode or attached to a charger.
[Verizon Droid Charge] usererror404:
Are you in a 4g area? If so, try turning 4g off and using CDMA only whenever you don't need it. Until the next wave of Qualcomm CPUs with integrated LTE modems comes out, having 4g on will be an absolutely vicious power sink.
[Verizon Droid Charge] donkason:
Copy that Usererror404.

I'll do that and report back what happens. It wasn't bad until a few weeks ago. That's what I find strange. Would something that simple cause 30-40% drains overnight?
[Verizon Droid Charge] buhohitr:
I don't think the issue with your 4g. I have 2 Droid Charge and I have my 4g on both of them 24x7 (never turn it off) and they sleep well. I think you need to pint point exactly what app is using your 4g. Download this app "Onavo | Monitor Data " from the market. This app will show you what app is using your data the most. Good luck.
[Verizon Droid Charge] donkason:
I ended up switching to Eclipse ROM defrosting my applications one by one. The battery draining issue seemed to be better after that.

So after a month of running Eclipse with no issue my phone is randomly waking itself. Every 10-20 seconds or so my screen turns on to the lock screen and turns back off, in turn causing my battery to drain again.

Anybody have a fix for this issue.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
I don't know anything about the scripts in the clockworkmods but isn't the backup and restore supposed to make an exact image and then be able to put it back the same way? So if your phone is able to boot fine through power cycles, reboots, whatever, then it should also be able to boot when that same setup is restored through clockwork.

I am asking this here so as not to get flamed in the CM9 thread. But it seems something as simple as adding a theme to CM9 stock causes the backup and restore process to fail when restoring a this setup ending in boot loops. I have never had this problem with CWM 5.0.2.7 MTD so was wondering if there is something different in the scripts between the 2 CWM versions.

Can a DEV please help me to understand what is going on? Is it something being looked at? I know there are more important things on the plate but was hoping that it is at least known and somewhere on the agenda list.

Thanks for all the awesome work on CM9 and all the CWM versions to the DEV team.
[Epic 4G Q&A, Help & Troubleshooting] LORDFIRE00:
Kenny, it might have to do with a boot sequence loop problem. Meaning, it might need some extra code in the boot sequence
[Epic 4G Q&A, Help & Troubleshooting] Cartmanz:
I was trying to back up data and wipe the cache and I keep ferrying this message. Can anyone help?
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Cartmanz, your question was answered in your thread. Don't use ROM Manager without setting it up properly.

As to the original question, the CM9 team got back to me and said I had to pull a logcat during the boot sequence. I googled that and it has to be done with adb while it is bootlooping. I will attempt this today. The CM9 team is awesome. We both agreed this is a low priority but something to be looked at down the road.

[HTC Desire S] foX2delta:
@Jahai

You will need to change the version-main of your phone to flash a RUU, so follow one of the downgrade threads here, it has the procedure to change the misc version and then install the old RUU (1.47.401.4 if you want to make it easier to root again, 2.10.401.8 if you want it to be the latest)
[HTC Desire S] Jahai:
Tried it already but if I type ./misc_version -s 1.27.405.6 it says that this isn't a directory :/

Can you say me what I have to do to change my mainversion?
[HTC Desire S] foX2delta:
Read through the whole downgrade thread's first. Lots of people have that problem. Then come back or post in the threads.
[HTC Desire S] chninkel:
Try this:

adb push misc_version /data/local/tmp

Hey, XDA people!

I'm currently using CM9, build 02022012.

got a single question:

I got a file on my PC, which I want to transfer to my phone via USB, as I don't have Wifi. Any way to do so, without reverting to other ICS ROMs? Sorry for the noobish question...
