Man, battery life for ICS LPY is quite bad. 57% with one hour 20 mins screen time plus awake like nearly 3 hours over 10 hours unplugged. Definitely needs serious improvement.

Hmm... can we use Gingerbread modems on ICS? I'm tempted to flash over LB1 modem to see if it improves battery life.

It is very safe to flash any gb modem on any ics rom
You cannot flash any gb kernel to replace any ics kernels

Thanks a lot uncle benny! I find my performance with 3G quite bad with XXLPT, plus I'm getting a ton of wakelocks related to l2_hsic so I want to try flashing back XXLB2 (reputedly best battery saving modem) to see if it makes battery life better.

I will report back later whether good or bad.

I had problems with l2_hsic keeping my GNote from sleeping.
But I don't think it's related to the modem. l2_hsic is a kernel wakeup, probably it's related to the kernel instead of modem hmm.gif
*
The reason why I suspect modem is due to HSIC is supposedly the interface used by the chip to connect to the modem (yes modem is connected via USB lol). You can read a little about it here: http://www.grandmax.net/2011/10/samsungs-e...-technical.html

Thus... why I'm trying out LB2 modem, which is reputedly the best power-saving modem out for Note so far (in fact a lot of ROM cookers seem to prefer it). I was previously on DarkyROM 3.4 with the same modem and it was doing a good job at battery life.

Anyways, flashed LB2 already. No problem with air interfaces so far, but the real test will be tomorrow smile.gif.

I'm getting more interested on Galaxy, and i'm going to get it this coming weekend!
I'm going to buy this phone from an AP-dealer due to i have limited budget.
So my question was this, is it ok buying an AP phone?

Thanks to ur opinions and million of thankss  notworthy.gif

Depends on your needs. AP set is cheaper, but warranty might be iffy.. though personally if you don't use it heavy duty or do a lot of risky things (like flashing ROM's biggrin.gif), AP is a good choice.

I got my Note from AP shop, use for three months now no problem so far. Generally, Samsung products can say quite tahan...

Wow wow. Thanks!
If i'm just simply using fews apps such as : - GSC, some FB apps games, normal websearch?
And i do like to capture picture or video thru the phone camera, thats once of my hobby too.
Music player is a must  biggrin.gif

So it belong to heavy duty category?

I think that's pretty normal usage.

You might... want to get extra batteries or a powerbank if you use camera/video a lot.

Seems like a solution to no deep sleeping German. ICS is possible. Phone finally back to GB level of battery life. I will share my findings later when i get back.

OK, I managed to somewhat get a little better battery life back on stock ICS XXLPY by doing three things:

1. Use LB2 modem
2. Uninstalled com.samsung.map (MessageNotificationService)
3. Disabled fast dormancy (in doubt, but no harm it seems!)

After that, I noticed a big drop in the l2_hsic kernel wakelock and phone goes in to deep sleep a lot more now. Improved my battery life by 10% over the same usage pattern.

This may or may not work for everyone, but so far I suspect the com.samsung.map is constantly doing something with the network thus generating a lot of wakelocks.

Still can't get rid of the AudioOut_1 wakelocks though, but as of now, battery life is a little more acceptable to me.

try disabling all the sounds (Keytones, Touch sounds, Screen lock sound) and give it a try.
I have significant less AudioOut wake locks after that..

I kinda like to have those though, lol. Not enough tactile feedback as it is.

Wait for mirror links
Main site OMG will take 20 hours!!
So far tested criskelo v3, midteam 1.2, alba v2 n kingdroid 1.1 . My verdict all performance about same except kingdroid slight lag. Alba I was unable to sync my chrome bookmarks dunno why. Would recommend criskelo or midteam for now

Rocket quite turn off as he uses kalagas theme which I find is too fancy n just horrible to me. But will still test it.

Agree on the kalagas theme. I hope eybee releases a zip to flash back to normal theme.

... seriously, Android themers sad.gif

Can't seem to download RocketROM... but the Kalagas theme is quite a turn off anyways.

Will continue to use German XXLPY, now with Supercharger changes in it, for this week and see if things slowly improve.

Day 5 on German ICS XXLPY + XXLB2 modem + V6 Supercharger

Well the ROM seems to be settling down, but I still find the deepsleep a bit flaky. Guess it's a "feature" of Samsung ICS brows.gif

Overall though, phone battery usage is much more saner now though, compared to the 40-50% 'Awake' ratio previously. Wonder what is causing the deleted_wake_locks...

One thing I don't like about ics is when I switch programs, from fb to browser, the browser reloads again..

And switch back to fb, for reloads again..
Previously loaded data is gone...

And no, Tubemate still don't work with fb in rocket v1 ics..
So sad..
*
Doesn't happen to me.... but I can suggest to try applying V6 Supercharger to see if it helps. Be warned though, applying it on ICS ROM is not for the faint of heart ^^;;

I still trying to understand the Supercharge V6.
Does this work with Litening ROM V1.0 plus Speedmod K12 Kernel?
*
Please read the forum thread. It explains pretty much everything the script does.

If you really want the short version:

» Click to show Spoiler - click again to hide... «


And yes, it should work on Litening ROM v1.0 as it's standalone script that applies tweaks to certain parts of the OS memory management.

hi guys... does the german ICS came with Polaris Office? I'm wondering if it work with AOSP/AOKP ICS rom like liquidsmooth or stunner.

Can someone help me to extract Polaris apk from german ICS?

Yes, it does. It should be the same .apk from GB. Extract it from previous ROM/nandroid backup from /system/app

Hi
Thanks. Well i do read it but confidence level is pretty much low plus confused and it is best to get some guidance from someone who have done it especially in LYF.

Cheers

Supercharger changes how Android OS memory management works by tweaking the minfree levels and modding the application priorities.

The main benefits are:

1. Launcher redraw are reduced as it it kept in memory.
2. Apps multitasking is improved. Apps wont get killed so fast.

In GB rom, you just need to run the script in terminal.
For ICS, you will need to mod system framework file manually.

Complete install instructions available on that thread. I also like to recommend reading the explanation of what the script does as it gives a good insight on how Android OS memory management works.
