Phone differences alone won't cause hours of difference in battery life, so that one can be marked off as too insignificant to matter (I doubt we'll be comparing the few extra minutes some phones may get - greater differences than that should indicate a problem with the lesser phone)

The rom is the same, so that should not even be capable of causing a difference if properly installed (good download, proper flash).

So that leaves the setup and configuration - installed apps, sync settings, etc. - maybe you're setting it up wrong?

But, the setup is something you do, so that means you would have to accept that, yes, you are doing it wrong ;) (for battery life, anyway)

But if that's how you like your phone, then you either have to accept the poor battery life, or re-evaluate the importance of the biggest drain factors...

In my case, I get horrible reception at home (even on TW roms), so I realized that my phone was only dying in 8 hours because it was either searching for, or struggling to maintain, a weak signal all day. I nearly doubled my battery life by turning data off while at home (I use wifi instead, and try not to find occasion for mms until I go into town where the signal is better, lol). I use a non-stock, 1550 mah battery, but I can still get almost 24 hours on CM9 with 2-3 hours of screen on time... if you aren't doing it wrong, what am I doing so right? ;)

Edit: just saw your most recent reply (posted while I was writing) w it sounds like you agree, you just don't realize that we're saying the same thing ;)

The factors you brought up are not a part of the rom, so you haven't defeated Zeinzu's assertion that the battery life is being impeded by something other than the rom (you have actually provided evidence supporting his claim)

High battery drain due to low signal will not disappear with a different rom (because reception is based on remote factors, and the rom is very much a local factor - it's in your phone, unlike the towers...) Perhaps TW roms handle the low signal a little better, but that only means the added drain on the battery will be reduced, not eliminated. But the wide variance of battery life among only CM9 users suggests that that issue is not significant to this problem - if it was, then there would be a clear association - all CM9 users would be on one side of the battery-life threshold, not spread across the spectrum.

So again, the only factors with a consistent correlation to battery life, regardless of the user and the rom, are the apps installed, the configuration, and signal strength. And your combination of apps, settings and signal seem to be conducive to a faster drain than Zeinzu's situation. Whether it's an app you installed, a setting you configured, or the area you chose to live in, it's something you did, lol (I'm aware that you can't simply relocate, several factors can keep that decision somewhat out of your hands - I included that part more to be a smart ass...)

There actually Is a thread for discussing cm9 battery life in General.
[Epic 4G Android Development] hotpocketdeath:
Having a Different setting does not make it wrong. And I in no way implied this.

I am also set up for Exchange with my work. Keeping it synced up will certain consume a fraction more power then someone who doesn't. Are you going to say my setup is wrong and his is right? This goes into the category of items that consume power WITHOUT it being user error, bad setup, or the ROM's fault. Please keep this in mind.

But I believe I addressed the other points fine with the post above yours.

No, I was not supporting his claim. He specifically said that people not getting good battery life are doing something wrong or expecting too much from their battery.

I was pointing out that there are other factors that determine battery life.

Custom flash of CM9 RC1 possible?

Hey gang, a couple questions for ya:

I've messed around with using WinRAR to open the CM9 .zip and remove some stock ringtones and substitute my own. I'd like to take this a step further and make it so that when flashing the .zip from recovery, it installs some of my frequently-used "must-have" apps (ie Nova Launcher, ROM Toolbox, Ti Backup, etc)

If I just add the APK's to the /system/app folder in the .zip, will that be good enough?

Also, is it pretty complicated to modify the .zip to flash a different kernel? If it's possible to just do this by swapping out a few files in the .zip, then I would just need to know which ones, I guess. I have a feeling it's just not that simple, though.

[Epic 4G Android Development] styles420:
@hotpocket - He said the drain is not caused by the rom. That leaves two things - coverage, and your setup (installed apps, and configuration of rom and said apps). You described your habits, which include an alarming amount of travel into no-coverage areas (and this is where you supported his claims, whether you intended to or not). Also, you provided stats for the rate of drain without airplane mode, so you must forget airplane mode often enough to know the usual drain - sounds like you just need to remember airplane mode more often.

The funny part was, after he said it wasn't the rom, and you provided real world examples that back that up, you still challenged him to explain how it WAS the rom's fault... if you still miss the humor, that explains a lot about the futility of continuing to try to turn on the light bulb over your head...

Zeinzu wasn't saying that your configuration is wrong in the same sense that murder is wrong - obviously, we can set up our phones how we choose, so there is no absolute "right" or "wrong" way. But it's no different than fuel economy with cars - if you take off like a race car driver, or tune the engine for greater speed or acceleration, then you have to expect lower mpg. If you have your email syncing 4 times an hour, even when you're in the mountains, then you have to expect your battery to take a hit. If you expect anything else, then either your expectations are wrong, or your settings are - that's what he was saying. And he is absolutely correct.
[Epic 4G Android Development] hayzooos:
Clean like Odin, no. I do wipe everything though, of course. As far as restoring data, really only to K9 to keep my account settings. Syncs aren't any different, and I'm in the same areas most of the time. Conference Center, office, home for the most part.
[Epic 4G Android Development] amateurhack:
Hey, we're 3200+ posts into this thread, why stop now?

Lol. ;^)
[Epic 4G Android Development] hotpocketdeath:
He said

He made no mention of coverage affecting him until after I said something. All I did was point out the flaw in this logic which you even agreed with.

Someone living in low coverage area can get terrible battery life. It's not that they are doing anything wrong, and I'm sure if the phone's user understands the situation, they wouldn't expect great battery life.

It's an arrogant assumption that everyone should get "fantastic" battery life just because you do and assume everyone else's conditions should be just like yours.

But if you must know, I'm at a point where I average about 1.5days on a charge, which I think is pretty good at this point. And I'm not forgetting about airplane mode. I just don't feel the need to turn it on just because the signal in the area is weaker then normal. I've only needed airplane mode that one time because I saw I was in a no coverage area. And just fyi, I get my stats from Battery Monitor Widget. It tells me what my consumption is at a glance.
[Epic 4G Android Development] zman519:
Ok can you guys give me a quick run down on what modems you gusy like & work good for you? I had ec05 on hear cuz I need stock to flash a prl 11115 & do some gps stuff b4 I flashed rc1. Now I FC09 on hear & its totaly slow junk even on wifi at home & my friends place right now.

BTW clean install did not data restore. I no better haha

Also my phone has always liked 1200 Mhz, any reason I should not overclock on rc1 it just seems slow to me, But Hell ya devs rc1 is grate I guess the only thing I'm NOT liking at all is the camera samsung did that one thing right on our phone

Since others ignored your question to continue the battery debate.... For adding the apps, this will work, but note whether you want to install to system/app or data/app. I don't know the kernel answer.

[Epic 4G Android Development] hayzooos:
Another thing you can do is go into TB and have it create your own TB.zip which will flash TB for you.

I've recently started doing this, and it helps quite a bit. I'll take out all the apps and such I don't want from whatever ROM I'm going to be flashing, put it on the SD, flash it, then flash the TB.zip so TB is already on there from first boot. Works quite well, then you can just restore any apps you want from there without so much as a data connection.
[Epic 4G Android Development] StoneRyno:
I've been concidering the idea of customizing the CM9 zip to include some apps as system apps instead of user apps. Are there certain apps that won't work correctly as system apps? I was thinking google maps, google drive, google play store, youtube, and gmail would all be good candidates as system apps. What do ya'll think?
[Epic 4G Android Development] GRK4G63:
I appreciate the helpful response! Thanks! :good:

About the Ti Backup flashable zip: I've already had Ti Backup create one just as a Plan B in case something heads South, but it would be kinda cool to have a version of CM9-RC1 with most of my stuff ready to go in it. I've already begun editing the build.prop to include a custom ringtone and notification by default. Since they will be on the internal storage instead of the SD card, it should work.

I guess I'm not too concerned about the kernel. It's not a deal-breaker or anything, it would just be kinda convenient and make it one less thing to flash.

Because there is 55MB of free space that could be used. That would be 7% more user app space. I always uninstall two system apps I don't use: google talk and google news and weather apps. I'm not sure how much of that was those two apps.

Any way to claim the free space from system part and make it user part then or does system have to have such a large amount of free space (20%) for functionality reasons?

The only issue I can think of, is with updates.

If the app is in data/app, it will be replaced with the updated version of the app, if the app to be updated is in system/app, you will end up with 2 copies, one in system/app and one in data/app.

IMO, you only want to place apps that typically dont get updated in system/app, or the latest versions of your must have apps, as in case you decide to do a wipe of data, they will still be there.

As for speed, my speed test is below, and while its not fantastic, its fast enough for me and cheaper than any of the alternatives.
[Epic 4G Android Development] amateurhack:
Well, to his credit, San Antonio and Dallas are about 300 miles apart. (In the northeast, that's like going from Boston, thru NYC, Philly, and Baltimore, and ending up in DC.) So maybe you can't really say that you would expect similar network performance in both cities.

On the other hand, I live in the Dallas area and get reasonably good reception everywhere I go regularly. I used to get better reception on my MotoQ back in the day, but that's a representation of the awesome radio on that phone, rather than a comment on Sprint's network.

Wimax is spotty, of course. But that's just the way wimax seems to be for most people.

I used to run CM9 beta3 & 4, but I ended up having a lot of freezes. I noticed it mostly happened in the official Google Reader app.

I went back to CM7.2 for a while and had no problems.

Enticed by the RC1 of CM9, I decided to give it a shot again. Lo and behold, I encountered a freeze while using the Google Reader app and had to pull the battery.

Is there anybody else that has encountered this issue? For now I'm using a different Reader app to see if that solves my problem.

Insufficient Storage Available?

I keep on getting "Insufficient Storage Available" on installing Chrome. I know it's an 18 meg APK, but I have plenty of storage available. I have experienced this before for previous apps on CM9 if I was getting an update, but not for NEW apps. (I have uninstalled Chrome fully from my phone and tried a new install.)

So, I googled it around, deleted any "Chrome" related files on my SD card, have also run Market Fix - but no luck.

My next thought is to format my SD card and re-flash with RC1. Before I do that later on today, does anyone have any last thoughts on what I could try? I have come across some answers about "SymLinks", still trying to figure out what files/caches I need to delete.

Thanks!

The easy way of freeing up space would be to use one of the management apps such as Android assistant to move some of your non system or non critical apps to the sd card move a bunch of them over and you will be able to install.
[Epic 4G Android Development] DonToolBag:
I have moved a ton over - currently at 211 megs free. It's definitely not a space issue, I've seen this come up from time to time for other users as well.

Flashing is the last resort, but I am just also curious as to why this is happening to fix again in the future. Flashing again isn't the end of the world - I do it once every few weeks anyways :laugh:

[Epic 4G Android Development] counterfeit187:
I have the same issue on the recent nightly builds. How many apps do you have installed, and how much available internal memory? I moved a bunch of apps to my sd card last night so I now have 177MB free internal storage space and can install apps again. The thing is I think some of that free space is allocated to /system instead of /data and doesn't allow apps to use it. maybe after the final build they will come out with a script that will let you pick your MTD partition sizes, I think decad3nce did this for the HTC Hero a long time ago.
