[A] [NAND] ROM Space and Battery Issues

I have picked up lots of bits of information about how to maximize space issues and maximize battery life for those of us who are in love with these amazing new NAND builds....especially those of us with European HD2 phones who only have 512MB to play with
I have compiled them below for ease of reference - I claim no originiality for these ideas...I am just bringing them together...so MAJOR THANKS TO ALL THOSE OUT THERE! You know who you are...
I have already posted this on the DFT thread as I love that particular build, but they should (might!) work for other builds and I post it here for further reference as it took me a long time to sift through the threads to find it all.
Space
1. Before flashing your phone, using DFT Stock Desire, for example, you can edit the flash.cfg file and change the following line:
cache ya 40M >>to>> cache ya 15M
This reduces the cache by 25M with no discernible impact on the speed of the build (imo).
This should give you in excess of 130MB free after a clean flash on that particular ROM. Expect that to drop to around 100MB once Market, Flash and a couple of other apps update themselves.
Some NAND ROMs will not even have this as an option, and others may look a little different. You can read about how the flash.cfg file is structured here.
2. Immediate install Z4 to root your device. You will need to get it from here. (Note: it may get stuck on 'Rebooting'. Wait a minute or so and then manually reboot - it will work fine and SuperUser will now work after the reboot)
Put it on your SD card and then install a file manager from the Market to browse to it and then install and run. Follow the details on the thread...
3. Install Move2SD. You can get it from the Market. Full details are here.
This allows you to move most (not quite all) apps to SD. It is the best option I have found to move most of those awkward apps.
I have now installed pretty much all of my apps that I used to run on non-NAND builds and have moved about 90%+ of them to the SD card. At time of writing I have loads of apps installed and still have over 70MB free
Battery
1. Install Battery Monitor Widget or Current Widget from the Market so that you have a way of tracking your current usage.
2. Install Set CPU - free for XDA members from here, but also available on the Market.
After setting your Main Screen to 'OnDemand' and 'Set on Boot', assign SetCPU a couple of profiles. I tend to use:
>> Screen Off: Max/Min 245000, Scaling 'OnDemand', Priority 50%
>> Battery <25% Max 384000/Min 245000, Scaling 'OnDemand', Priority 50%
You can play to your hearts content here, but these give me consistently 7ma in Standby.
Also, you can reduced the sampling rate to 20000 and 'Set on Boot' in Advanced if you like.
3. Avoid power hungry background stuff like animated wallpapers and turn off GPS, Wireless etc. There are LOADS of apps out there that can do this automatically for you free from the market, but I have found that making sure my GPS is off (I have a widget to show me) plus SetCPU is plenty. It may work for you though.
4. Some have reported that Darkstone's suggestion makes a major difference to their power consumption:
"To fix high power drain / usage in standby (60mA or 70mA) disable 'Use wireless networks' in Settings>Location menu. You will now get 7mA or less constantly. I discovered this as the main culprit last night. Also works in other builds."
Anyway, there you go - a few consolidated thoughts - happy NANDing!

SetCPU doesnt work on Nand ROM..Is there any similiar program like SetCPU for Nand ROM ?

well guys i really dont understand why everybody you complaining about nand build
well my nand build is nexus one and i get 2-3ma battery drain in standby
olso the spuset in on 1190smartass

i dont want to be a smartass guy, but please ram and rom is different
ram = random access memory
rom = read only memory
when i look at the thread title of couse i think about ram, not rom... and too much thread title have that 2 things mixed in and im sure that will make alot of people (including me) confused
btw i thank you for the info

economy kernel

hello.
could you help me to chose economy kernel for my device i9000.
i need more working time on my device.
thx for answers

Well, if you are willing to sacrifice some power you could underclock with Damian's ultimate kernel and as well undervolt (whatever your phone can handle)
apart from changing the kernel, have you tried tasker? this app can really help you to save some battery...

I dont no about Kernels But ive heard 'insanity' ROM is amazing on battery life without losing speed and features.
check for it under development and see what Kernel people are using with it.

i try to underclock CPU but program that i use cant use all frequency only 100 - 500 mhz.
can you give me advice what program can underlock CPU and good task killer.
i need much web serfing

as for now, try damian's kernel, underclocking setting is in the recovery menu. As far as I know, he is working on an app for the new kernel but just try version 1.1
Concerning task killers, I found out that they do more harm than good. Don't use them...
The problem with web surfing is that the display is on all the time (what else?!^^) and it consumes a lot! there is not much one can do about it...

how can i reduce consamption of display? can i change white color on black in browser? to reduce consamption of energy?

I assume you have already set brightness to minimum, in addition you could use the app "screen filter" which makes the display even darker but then it is only readable in the dark.

Do you set your brightness to automatic ?? thats a big help
As for changing display color i dont know if thats possible, unless you can find a themed version
EDIT: sorry just noticed the above post

and say please One Click Lag Fix APK decrease or increase reducing power?

lagfix will always reduce battery life, but the more updated lagfixes use less, but still use more than stock.
Have you got the app "juicedefender" thats a good app and i have been using it daily for months.

I ran some test cycles with speedmod and ultimate kernel with both standard file system and converted system. Therefore, I can say that just changing the filesystem does not influence battery life in any way noticeable.

as i know One Click Lag Fix APK change only file system?

its not MEGA improvement but the donate version has more options. what it does is cuts off all connectivity on screen off, so nothing is being used when it shouldnt be.
its really good IMO, and the partner to the app is 'juice plotter' this will identify what running processes are happening when the phone is idle, allowing you to modify to save battery life a little more. another similar app which is also good but a little hard to understand is 'task identifier' this is similar to juice plotter,
it tells you what apps and processes are starting up automatically. Over night i found 48 processes happening when i was sleeping. THAT drains battery

What exactly are your battery stats?
how long does your phone last on one charge? how long is the display on? how long do you call?

I like speedmod's modification on screen brightness that allows for even lower brightness than I got from voodoo kernel. No idea if other kernel has such feature.

on one full charge i get roughly 2 days.
display is on automatic and i make about 5 - 10 calls a day, and text all day, i manually push emails every few hours and browse the market / xda / youtube for a few hours a day.
Im not a heavy user, but i play alot of games ( especially angry birds ) im more than happy with my battery usage.
Im also on the JQ1 modem, if this is of any use.

If you want to use screen filter, leave the brightness at automatic and it is great in all but the brightest sunlight. I use auto brightness and 60% filter to good effect. You can create a widget, so it can be turned off if required. It also plugs in to Tasker if you want to set up automatic profiles.
Also, the Super Optimized Kernel is worth a look. Each OC/UV value can be completely customized (unlike DamianGTO's kernel, which relies on a series of presets), using the "Voltage Control" app.
I would stay away from Ext4 lagfixes if battery life is of upmost importance. That said I use lagfixes and am torn between JFS and Ext4 with 'unsafe' mount options (selected in recovery). EXT4 with 'safe' mount options uses far too much battery IMO.
JFS is somewhat unstable, and EXT4 'unsafe' can become corrupt after an improper shutdown. The battery life with ext4 'unsafe' is slightly worse than JFS, but you get a corresponding slight increase in performance. Try each for a day if you go that route before choosing, but for the reasons described above be prepared to reflash in case of disaster...

[Q] cpufreq parameters without using 3rd party apps

Hello.
I've got a stock Android 3.2.1 (A501 4.066.29 COM GEN1) rooted with Stock/HV/Taboonay V3.7 for HC 3.2 16-10 - 1.64Ghz/UV control kernel.
The question is:
how to set cpufreq parameters (governor, max_freq,..) WITHOUT using 3rd party apps so that the parameters were restored after reboot.
Thank you for reading this.

Either the kernel needs to support init.d scripts or a service needs to execute on boot.
That kernel doesn't support init.d and Voltage Control has a startup service.

Forgive my ignorance but I can't put to use your answer.
I don't get where is Voltage Control and what I have to do.

Get Voltage Control from the market, make adjustments, save as boot. You'll be given the option to save as init.d script or startup service.

Well.. I tested it. Odd app.
First of all it can see only one core. It's funny. After reboot cpu0 works in conservative mode, max_freq 1.4 GHz and cpu1 in ondemand mode, 1.0 GHz.
I tried to edit init.d script and add the 2nd core but after reboot cpu worked with the default kernel values - script didn't work at all.
Moreover Voltage Control shows voltages turned upside down - the less cpu frequency the bigger voltage values. I fear to use this app

Download setcpu or antutu cpu master it recognizes dualcore , has the boot option

More education would be advised To you PLEASE DONT BREAK YOUR TABLET
Please do not take this the wrong way..
it does sound like you do not know what your doing.. I suggest you read more about over clocking./under voltage of a TEGRA 2 DEVICE.. That will get you more understanding about what you need to do. And maybe even help you decide if you really want to do this or not.. There is alot of resources online about this subject. I have tried custom kernel with set cpu.. I use it on my 650 mhz phone. clock it to 768. but it has a huge battry issue when running at that speed.Not to mention It would be dangerous to leave it on my purse with something running might be a fire bug.. GOOD LUCK .

Basically lower voltage at higher frequencies keeps the CPU stable. Leaving it linear would increase temperature exponentially.
Script Manager can run scripts on startup but I don't know how you could disable them if they keep it from starting up.
I didn't know about VC and dual core though. My bad.

I don't understand? You want something that does the same thing but you don't want to know it's there?
I found one app called System Tuner that lets you adjust CPU frequencies individually. I don't know why though.

Actually I don't like how these apps work. And I thought that setting up a few parameters would't be difficult. It seems I was wrong.

Yep. Code has to execute to do stuff, otherwise that stuff doesn't get done.

System Tuner Pro allows voltage adjustments on overclock settings. If you're interested. Also, has a lot of packages integrated into one (task manager, app freezer, etc). They have a free version in the Market if you're interested. It's nice to have several apps, in one nice package.

It's because the 3.7 kernel you used, is really not compatible with the a501. The ultra-low voltage causes "screen freeze" and the "sleep of death" when under 3g only. It's a known issue with the 501 and 3.6 and 3.7 kernels also. I would reccommend RTrips 3.4+. Probably his best for for a501.
I ship it with my own Alexandra II and III rom. No issues with it, and none ever reported.
Had I noticed when I woke this morning, you had an a501, I could have given this advice. Sorry, didn't have enough coffee

The problem, is that a lot of dev's, don't have a501's, only a500's. So they really can't test a lot on it. And sometimes, the issue doesn't happen for 2 or 3 days. Sometimes less. I'm going to experiment a little this weekend, with some of the newer kernels, and mess with the voltage's and see if I can get it stabilized where it doesn't freeze on 3g only.

Moscow Desire ,
Thanks for clearing it up and the advise. I'll try either 3.4 kernel or your ROM.

If you go to RichardTrips kernel thread, you will see a link to his older kernels.
You will find the 3.4 listed on his server. I think you just need to flash it, although I usually dump Dalvak cache.
Alex II is an easy install. Alex III (3.2.1) is a little more ... interesting to install, but not difficult. If you run into an issue, post it in my thread. Everybody else has got it installed, so I think you'll have no issues either.
It's the only "certified" 3.2.1 for the Acer a501 that I know if. Not that the other roms are bad, because they really are good, but, the 3.2.1 they advertise, are from system dumps after running an update, or adding missing files to a 500 rom. The TMPL is an Acer release.

I highly recommend doing the battery optimization first before customizing the settings.
First thing you want to do is change the default notification from Silent to something else so you hear when you have emails, texts, etc.
There is a lot of stuff in the optimization guide to help you get things started and set-up. I like going into the Messaging app and have it not only divide texts into 160 character blocks but also number them so people know the reading order as they aren't always sent and received contiguously.
I think that is a good start for now!

Being a CM9 user since day 1 I figured out that you will NEVER want to use an app form the market which allows you to change the frequencies of your phone. I found out that it drains battery EVEN MORE then when using the built in one under Performance.
And I highly recommend that you get Juice Defender. Ultimate is best because it allows you to choose what apps you want to have data turned on for.
And if you monkey around with Voodoo control I'm sure you'll find something to your likes.
Screen Filter from the market is also a great tool. If you think the lowest brightness is to much and want it darker then use that tool.
I recently learned that custom kernels are not recommended.

I'd like to know how this is possible. I mean, if you're undervolting (throwing less power to run a specific speed) I would like to know how this actually drains battery quicker. It simply goes against logic.
Not saying I don't believe you, but I would like it explained why this is true.

Yes it did all of that as with any tw rom when you do fresh flash and set up phone. I even just for nostalgic reasons played the two set up messages. But I then used my wife's phone and called myself and left several voice messages but nothing comes through the app. I read everywhere people having success with this and I'm struggling. I even tried sending the [email protected] message and it looks like it sent but nothing happens.
Edit: I am getting the text messages alerting me that o have a VM but the app is not downloading the messages. I still have to dial #1 on dialer to dial my voice mail.

I get a 9016 message with provisioning successful but if there was a toast message it was so quick I missed it but I don't think there was one. Does this mean that I need to delete data for the app and try again or does this mean it provisioned but like edfunkycold I too get the text messages about new VM but the app doesn't download them. In fact the messages aren't on sprints VM system like the app told it to delete the message as if it had downloaded, even though there is no message in the app to listen to.

Well its mainly for those who leave it in their pocket for long periods of time. Because if you have apps like twitter, facebook, or anything like that they run in the background and the cpu will require more power to run them all. Now if you used an app from the market to control them it would drain battery because it requires battery to run apps in the background and that app you supposedly have from the market will run in the background, thus causing battery to drain even if you're under volting it.
If that wasn't very clear tell me.

Same problem here, except I dont think that mine are getting deleted, cuz I can still call my VM and listen to them. But for the life of me I can not get the VVM to work, I have tried absolutely everything I can think of. Please if anyone can figure out what the deal here is, it would be greatly appreciated. The loss of VVM was pretty much the only thing I didn't like about This CM9 for Epic, since I flashed the alpha 1.
Edit: Just an update: when I use Sprint VVM to compose a message to myself, to test send and receive functions, It sends the VM to me just fine. I get the 9016 text and its on my VM but It still does not show up in the Sprint VVM app.

Exactly how I tried to test it except the message I composed and successfully sent was not on VM when I call in after getting the 9016 message saying I got that VM. This is what leads me to believe that sprint VVM is failing to download the message and deletes it from the VM system as if it had.

I see where you're coming from, I think. So you're saying Voltage Control, for example, would be running more frequently if I have a lot of apps that update in the background becuase in addition to those apps running, VC would then have to run more to produce more power to run the other apps.
I guess I was under the impression that VC would run at boot (however you have it set up) but it wouldn't continue to run once the settings were in place. For example, I never see Voltage Control as an app listed in the running apps or or cached processes for that matter either.
So then my question becomes if it's not an active running app, and it's not a cached app either, how is it draining more battery?

i dont think it does. i never see it as a running app, and it doesnt show up as using the battery in battery stats, so i think this guy is misinformed on that aspect. if youre using undervolted settings with the ondemand governor, you probably wont be using more battery than on stock. im in know way absolutely sure of this and im not a dev or computer genius or anything like that, but im pretty sure the battery problems that DO occur are on the custom kernel side. since a custom kernel is needed to overclock and undervolt, and some of the 3rd party kernels have had some battery draining issues, like wake lock issues and stuff, i can see where one would get the impression that using an oc/uv app might be causing battery draining issues. i myself am using the shadow kernel which oc's to 1400 mhz and at first was getting terrible battery status. but after messing around with a few settings, reading up on tips for saving battery, and tweaking juice defender ultimate to my liking, im getting exceptional battery life. almost as good as the stock kernel. i would have dealt with a bigger difference in battery drain for voodoo color anyways. not to mention, the added bonuses of being able to oc/uv. im in no way trying to knock the stock kernel, my preference is just that, my preference.
as far as a custom kernel not being recommended...thats easy, its also not recommended to root your phone or flash a custom ROM. nuff said, right?
p.s. while voltage control does NOT show up on my battery stats, juice defender ultimate DOES. VC does NOT seem to be running in the background at all times, but JD definitely IS.

But for the life of me I can not get the VVM to work, I have tried absolutely everything I can think of. Please if anyone can figure out what the deal here is, it would be greatly appreciated. The loss of VVM was pretty much the only thing I didn't like about This CM9 for Epic, since I flashed the alpha 1.
Edit: Just an update: when I use Sprint VVM to compose a message to myself, to test send and receive functions, It sends the VM to me just fine. I get the 9016 text and its on my VM but It still does not show up in the Sprint VVM app.

So after a big long ordeal (accidentally flashed mtd over bml and soft bricked my phone for a day lol ) I finally got it fixed with odin. Then I managed to get back to a working backup that had a working version of Sprint VVM and backed up the data with titanium backup then got my cm9 beta 0 restored and flashed a fresh version of SVVM then went in and made sure it was set in the dialer settings and then restored the app data and the provisioned and still no damn luck.

p.s. while voltage control does NOT show up on my battery stats, juice defender ultimate DOES. VC does NOT seem to be running in the background at all times, but JD definitely IS.

This is because VC loads the custom changes at boot time and is no longer needed. Where as JD is a service that performs periodic actions based on how the user setup JD. In essence JD will consume a slight bit of battery but the increase in savings will outweigh it's consumption. If anyone would like I can try and determine JDs exact usage if it registers in any of the available tools for checking apps battery/CPU usage. As far as I'm aware it does not show up in androids battery info section commonly used to show battery usage in screen shots here on the forum. I of course would post those findings if any in the battery thread.

For those who can't enable the native HOTSPOT as reported on issue 148, try side-loading android-wifi-tether.
With AWT, I can have AP infrastructure hotspot using netd, with WPA2 encryption and multiple Android devices connected. The trick is to configure the device profile as an Epic 4G Touch, Galaxy or any Samsung device that shows netd option in the Setup-Method. Optionally, turn off driver force-reload to get rid of a harmless error message (works fine either way).
A nice thing about AWT is it shows the hotspot real time, accumulative bandwidth usage, and if you don't need to use AP infrastructure mode, you can even lower the ad-hoc mode transmit power for lower battery use.
It also has MAC-based client access control, and on TW ROM, it would give hidden SSID option.
(sorry for posting this multiple times; just thought I'd share my finding on all the relevant threads.

ok what sound manager app is better....
i have bought voodoo
I know that DSP comes with cm9...

I use Voodoo (paid version) so I can limit the headset volume on my kids' Epics.

FYI: For those of you that are having issues with VVM, are you using GoSMS? If so, it's been posted in the CM9 tips and tricks thread that GoSMS and Sprint VVM dont play nicely with one another.
Freeze or Uninstall GoSMS and your VM's should start trickling in!!!

Suggestions to Debloater v1, [KERNEL][ROM][MOD] arman68 DIY

Because I have no posting rights in developer forum, I am posting here.
I have found a little tiny typo in debloater_v1 which prevents the uninstall of the shown:
Code:
# - Market Feedback Agent
#delete("/system/app/[B]Google.Feedback[/B].apk","/system/app/[B]Google.Feedback[/B].odex");
shoul be:
#delete("/system/app/[B]GoogleFeedback[/B].apk","/system/app/[B]GoogleFeedback[/B].odex");
What don't work in the script, is the "LiveWallpaper" removal. I think the path or name is wrong, but don't know it correctly, I removed it with Titanium Backup.
Then I've added following stuff, because I don't want it. Maybe someone don't need it too:
Code:
# - Partner Bookmarks
delete("/system/app/PartnerBookmarksProvider.apk","/system/app/PartnerBookmarksProvider.odex");
delete_recursive("/data/data/com.android.providers.partnerbookmarks");
# - QuickOffice
delete("/system/app/Quickoffice_sp.apk");
delete_recursive("/data/data/com.qo.android.moto");
# - Audio equalizer
delete("/system/app/MusicFX.apk","/system/app/MusicFX.odex");
delete_recursive("/data/data/com.android.musicfx");
# - Videoeditor
delete("/system/app/VideoEditorGoogle.apk","/system/app/VideoEditorGoogle.odex");
delete_recursive("/data/data/com.google.android.videoeditor");
# - Google Talk
delete("/system/app/Talk.apk","/system/app/Talk.odex");
delete_recursive("/data/data/com.google.android.talk");
# - Google Play Music
delete("/system/app/Music2.apk","/system/app/Music2.odex");
delete_recursive("/data/data/com.google.android.music");
# - DLNA
delete("/system/app/DlnaSystemService.apk","/system/app/DlnaSystemService.odex");
delete_recursive("/data/data/com.motorola.android.dlnasystemservice");
# - Modem Panic reporter
delete("/system/app/ModemPanicReporter.apk","/system/app/ModemPanicReporter.odex");
delete_recursive("/data/data/com.motorola.modempanicreporter");
# - OMA protocol for Device Management
delete("/system/app/OMAProvisioning.apk","/system/app/OMAProvisioning.odex");
delete_recursive("/data/data/com.motorola.android.provisioning");
# - Motorola Service ?
delete("/system/app/cce.apk","/system/app/cce.odex");
# - Other Crap
delete("/system/app/PhoneAddons.apk","/system/app/PhoneAddons.odex");
delete_recursive("/data/data/com.motorola.phoneaddons");
delete("/system/app/PhoneConfig.apk","/system/app/PhoneConfig.odex");
delete_recursive("/data/data/com.motorola.hiddenmenu");
delete("/system/app/DataSwitch.apk","/system/app/DataSwitch.odex");
delete_recursive("/data/data/com.motorola.dataswitch");
I've found this as a major useless battery consumer and removed it too:
Code:
# - Statistics Service
delete("/system/app/ModemStatsService.apk","/system/app/ModemStatsService.odex");
delete_recursive("/data/data/com.motorola.bach.modemstats");
Because I also used the "remove_motorola-launcher" and replaced the launcher with apex, I added the following at least:
Code:
# - Deblur
delete("/system/app/BlurUpdater.apk","/system/app/BlurUpdater.odex");
delete_recursive("/data/data/com.motorola.blur.updater");
delete("/system/app/blur-services.apk","/system/app/blur-services.odex");
delete_recursive("/data/data/com.motorola.blur.service.blur");
delete("/system/app/Setup.apk","/system/app/Setup.odex");
delete_recursive("/data/data/com.motorola.blur.setup");
delete("/system/app/SetupSettings.apk","/system/app/SetupSettings.odex");
delete_recursive("/data/data/com.motorola.blur.setupsettings");
If someone knows how to remove the flash player settings app through this script, on which I get an error on opening and removed it therefore by hand, then let me know.

I've forgot to thank arman68 for the good work and mod.
Edit (as a bonus info):
I noticed the following in case of battery consumption and cpu governor.
I highly recommend to use SmartAssV2, if you switch the screen off. For me it's the best governor in sleep mode with very low battery consumption.
So I used a profile where I switched between SmartAssV2 in case of screen is off and InteractiveX when it's switched on.

Hey Machredsch, this is great feedback, thank you.
I will have a detailed look at the information you provided, and use it for v2.
Did you really find a big battery usage difference between smartassV2 and interactiveX with the screen on? Theoritically, smartassV2 should have a small advantage, but I am not convinced it would be enough of a difference to justify switching with a profile. I will try to do some tests.
With screen off, interactiveX definitely has a clear advantage, due to the 600MHz limit.

I once used Omars ROM and I used the InteractiveX permanently. The phone was mostly off and unused. Over night I was on WLAN, during daylight on 3G. I noticed a rapid lost on battery and don't know why, therefore I switched to SmartAssV2 and for me it has been worked best since, if you do nothing all the time. I also noticed InteractiveX performing better in case of battery, when you do something with your phone.
But this is only my personal subjective impression with no test material or something else. If you or someone else could make some tests, it will be an enlightenment for all. But because I am satisfied with this setting, I always use this in that way.
At some thread, I don't know where here, I read about a benchmark test (which wasn't accepted by the others ) and there was the opinion, that SmartAssV2 was most time at sleep mode of all governors, if you did nothing. But that was only was I understood.

When the screen is OFF, both governors are very good at spending most of their time in deep sleep.
In the case you reported, it seems like something was preventing deep sleep on your phone. It could be an application running, some wakelocks, or network related. The fact that you were on interactiveX actually helped your battery last longer, since it made sure the CPU did not go beyond 600MHz. If you had been on smartassV2, your CPU would have scaled all the way to 2GHz, and drained your battery much faster.
I suspect, after you changed governor, you must have rebooted or changed some other setting, and this is what solved your deep sleep problem.
I have done some screen OFF tests that clearly showed smartassV2 runs down the battery much faster when the phone is prevented from entering deep sleep. Deep sleep prevention can happen for a variety of reason, including the simple fact of being connected to a wifi network (a bug in android wifi stack causes constant rx_wake events, under specific conditions, when connected to some wlan networks). This is why I have set interactiveX as default in my kernel. In addition, in my performance test, I could not find any difference between the two governors.

Ok thx arman for the detailed explanation, I will try.

I tend to err on the side of caution, especially for a debloater script published publicly. Do you know what the ModemStatsService actually does? From the name, isn't it related to the Settings > Data usage option?
What about the following:
DlnaSystemService
ModemPanicReporter
cce
PhoneAddons
PhoneConfig
DataSwitch
How about the apk you listed under Deblur; are you sure they are not needed anymore once the Motorola launcher is gone?

First, I havent't any problems with the removal of all of them, I wrote.
I only noticed that the small cloud icon of USB-Debugging in the status bar disappeared, if you connect the phone to USB.
Second, my suggestions depend on this list from another Motorola Phone and Version 4.0.4, but I think most of them are the same or similar:
App list
There was written, that removal of some Google apps like Google Play Music isn't possible, but it is on our phone.
And if you look at "ModemStatsService", you can read "Statistics Service data, wich does not alter the connections. Major consumer of battery." I've found it very helpfull and I had no problems with removing of it, on the contrary I noticed only advantages.
Because I don't want Motorolas Email client and don't want to update and sync with Motorola services or accounts and updates, I don't need the apps. Maybe someone can confirm my points or have some experiences with it. I know no advantages of keeping those services on my daily usage. Data traffic and statistic and contacts sync and so on is still working.
"Motorola Service" I don't know what it does, when it was running. I removed it and noticed nothing happens, except no service of it is running.
On this site in German, they say you can remove cce.apk: system-apps removal
"DLNA" you can google for it, I don't need it. If you add an option for it and disable the removal by default, I think there should be no problem.
PhoneAddons
PhoneConfig
DataSwitch
Maybe someone should dig more into it and look what exactly they are for. I noticed no problems after removal, but I clearly say, I test all of them only by daily usage and nothing deep. You can stay with them and don't take them away at the moment as long as someone else could explain more. "DataSwitch" sounds important to me nevertheless . If DataSwitch stands for 3G/2G switch or something related, it should clearly stay.

OK, here's the explanation. There was a profile active, which switched to SmartAss when screen was off and there was set the max frequency to 600 MHz, So there is no wonder that I had best results.
