Downgrade from JB to ICS rooted

Hello, my Motorola Xoom Wifi (USA) is running Jelly Bean Rooted and it totally sucks, because my battery usage consists of 50% Android OS and only 30% screen which is just insane.
I was wondering what I have to do to downgrade my xoom to ICS? Because then my xoom battery lasted for 5 days, now it takes 2 days.
Thank you

you got me on that one, battrey consist of 50%, you may have something running in the background that is killing the battrey life, it's not the OS, my xoom OS is 2% my screen is 83% because of my setting..
onece a month i will let my xoom battrey drain all the way intil it die then charge it....when i read about 5 days of battery life i know that the xoom don't do anything but sit there with just the power on and don't get any meanfull usage...

Any idea how to check which bastard is sinking my battery?

I use juiceDefender Ultimate it has many options to set, try it for a few day's before you go backward to ICS...

imo to downgrade from jb to ics u should flash an ics rom. At least, im flashed honeycomb rom on jb and all was nice

[MOD] Eliminate Wakeup Lag - XXLSZ

Hi guys.
Here is a mod I made to eliminate wake up lag on lock screen when pressing home button.
this mod is on the file androidpolicy.jar
my mod includes 4 way reboot and ink effect (WITH PEN ONLY)
download file and flash in recovery.
Thanks to MIKEYXDA for How To.....
Feel Free to use this in your ROMS, but please give credits
this mod is for LSZ!!!
PLEASE READ: This mod adds a wake lock to your phone and could prevent it from going into deep sleep.
I've added the Q and A from MIKEYXDA guide so you can make up your own mind.
please make a backup first!!!

Just to let users know this mod may not put your phone into deep sleep coz what the mod does is create a partial wakelock - that is how it enables zero wake-lag.

That is a very good point cyanoxide.
I will do some testing with cpuspy and see whats happening.

if this mod really make phone not going to sleep..it will make battery drain faster..

here is the Q and A from MIKEYXDA guide:

I did a lot of research on that and it's not so easy to answer. Generally, I believe battery will be no worse and possibly better. Google location services, alarms, widgets, push mail, and many other processes end up waking up 99% of phones at least once every 3 minutes anyway and the deep-sleep-->awake-->deep sleep cycles actually consume more power than letting the processor(s) stay awake. On my phone for example, Google location services alone woke the phone 20 times/hr (every 3 minutes) and that's with GPS turned off and no navigation or map activities running! Add a weather widget here, a push mail app there, and I found that my phone was bouncing in and out of deep sleep more than a hundred times an hour! Better (on both battery and circuitry) to just idle at that point. With only one CPU awake with screen off, the radio will draw more power than the CPU idling. Most people don't realize that the screen and radio eat orders of magnitude more power than (especially an idling) CPU, so idling one CPU will have little effect on battery. That said, I suppose if you put your phone in airplane mode and maybe froze a bunch of other apps that wake the phone, maybe battery would be worse with the ZeroWakeLag wakelock and the phone would do better in deep sleep. Reality is: we don't use our phones that way.
I guess the only way to test this is to run the mod for a while and see how it goes.
my battery I ****ed anyway and I have to charge twice a day so its not much of an issue for me, but for all you battery hungry folks out there it may cause issues.
would be nice if users could report any differences they see and we can together figure out if it is more of a hindrance than an advantage

deleted...should better read myself

Thanks.

forget it...was for homebutton doubleclick lag...yours is for homebutton lag on lockscreen...sorry

First thing you should know is that I am not a technical person, but a logical man. Following is my personal views. This mod may not put the device in deep sleep at all. In the cpu spy you will find above deep sleep, 200, 500, 800 mhz bars. Normally you may find even the deep sleep shows a good % the other bars 200,500,800 also show varied %s.
So may be this wakeup lag mod control these 200,500,800,1000 mhz to near zero, then overall battery consumption could be very less. Only experiments can answer this.
I shall flash this and see any difference.

I don't care that small lag, cause I know as long as it is present, my device was in DeepSleep ...someone would have to test it for 1 day or so and check with CPUSpy if DeepSleep is 'normal' or not...

after almost a full day of use I can confim the device is not entering deep sleep.
spending most of its time running at 200
do you think this will have a massive affect on battery life?

Actually I was waiting for your reply.(pls refer my earlier post). Another thing is I have already got 4 way reboot and ink effect. I just wanted wake up lag mod. Any way I shall flash. Already made backup. Let you know after 24-48 hours. Thanks.
Rom: Team Union V6 Full.

The problem with this mod is that it is integrated into android.policy.jar and if users wanted to disable it, they will have to flash the original android.policy.jar of the rom they are using. To achieve the same effect without modifying android.policy.jar, xda member sms200 has made an app that integrates this zero wake up lag in his app and users will be able to test or use it at will. HERE is the app and HERE is the post for more info. Just install it and enable/disable Permanent PWL.

I read through most of that tread and missed that bit lol
What ive done is copy original androidpolicy inside framework as androidpolicy.jar.bk and then copied original so i can revert at anytime. This is included in my rom aswell (both files)
Feel free to use my mod or the app depends what users prefer.
Dsmas - the 4way reboot and ink effect is included because if i didnt and you flashed the mod you would lose both functions.
Ive been testing some sharedpref mods and a remote control app so i might be able to create something to enable/disable in my galactus mod pack (WIP see my rom thread)

battery drain

hi i have the usual problem with my samsung galaxy S i9003: my battery drains extremely quickly. on the battery usage it shows that the display is what is draining my battry the most, but the problem is, it is on its lowest. i just don't know what to do, i wiped the battery stats, i downloaded lots of programs to save battery, i removed the google backup transport apk, i don't use wifi, 3g, gps, bluetooth, i don't play games, i really don't know what else to do.
so please, help me.
i bought the phone from another person, so it's been already used.
i'm on gingerbread DDLF2, i'm rooted and have already tried a few roms but had the same problem, if you know of good, stable, smooth and for daily use rom please let me know.
ps: my phone doesn't show real battery stats, what i mean is, when the phone is on 30% it just shuts off, and when i plug it and turn it on, it shows 0%. it has happened since the day i got it.
ps2: i don't know if this matters but, i soft-bricked my phone like two weeks ago trying to restore the stock rom from a remics rom, and flashed the stock rom to get it back.
the battery drain problem has been there since before but i just wanted to put it out there to see if it helps.

can you tell me for how many hours your battery lasts after fully charged.
battery usage also depends on cpu usage ( like if u have set your processor limits to high ) or may be because you have lots of apps running in the background. you can try installing watchdog application to trace whose eating up your battery

I experienced battery drain too on GB ROM. I guess that newer apps are using android functions that are not coded very efficiently on GB.
I was surprised that battery life got much better after flashin to 4.4 kitkat. If you want to give it a try, I definitely recommend trying out flashing your device and see whether battery life improves

yes.... can try out different rom or some other kernels too. and try changing processor to some battery friendly mode like " conservative " or tweak the default processor to save battery.
and try out greenify app if you are not using. @luligorla

what i'm worried about is that the display is literally on 0%, isn't it weird?
i tried flashing 2 different roms and with both the battery drained just the same. if you know about any stable, smooth and for daily use rom please let me know!

Need recommendation for KitKat rom

Hi,
Every KitKat Rom that I tried was affected by some kind of battery draining bug which has to do sth with Google Play services. Can you recommend a fix which works by doing it a single time? Uninstalling/stopping Google play services fixes the problem for a few hours only.
However, I would prefer a rom which is not affected By the bug out of the box.

I'm testing Racpu_ cm11s. Was having Google Play service wakelock, but learned somewhere on Oneplus forum about this: Install Disable Service from play store, switch to system tab, check SystemUpdateService. That somehow eliminates the wakelock. Today is 2nd cycle, 4hr screen on for youtube netflix under wifi, still rocking 48% of battery.

Cool, Ty, didn't know about this Bugfix,will try it. Why are you testing kitkat Roms in 2016?

Now I'm on slimsaber kk build, about the same SOT, feels slightly smoother than cm11s maybe.

Since I opened this thread, I am on Karbon kitkat which seems to be a fork of Slimxxxx
Fortunately, I did not get an always active bug until now, so I didn't try your Bugfix.
How much SoT do you get with your roms and which configuration.?
Most times I get 4 hours with the following config
- brightness static 50%
- sync, tapToWake and offscreen gestures off ( just in case...)
With following usage profile:
- no 3d
- no video (out of short clips)
- chrome, messenger, quora, Google news
- telephone 45min
- 75% WiFi, 25% 3G

With Racpu's cm11s and Slimsaber KK build, I didn't get to use the battery all the way to like 1%, but I already got 5hr SOT before that. Here are more details.
Racpu's:
- auto brightness
- youtube and netflix a lot, some xda and chrome, abou 30min phone call
- always on wifi
- greenify in exposed mode
Slimsaber KK:
- auto brightness
- 3hr LTE, rest on wifi
- about 2hrs of youtube and netflix
- 40min navigation with google maps
- a few camera shots
Don't think this is scientific enough, but hope it gives some idea on my usage.

YouTube, video in general does really really impact SOT measurements. You get about 1,5 to 1,8 times more, I measured it a lot. Navigation is the other extreme : 3d, GPS and most times a high brightness because you are outside (on daylight)

Ah OK, that seems right. I didn't do such detailed research
Now I'm leaning towards what most people say: Battery life depends on how you use the phone.
Also, I think OPO has an amazing developer community and all roms are of high quality and yet retain their own unique qualities like functions etc.

which is Best battery & speed rom/kernel

I'm looking for someway to get best battery backup with good screen on time without compromising phone speed (mainly for multitasking and app open times)
Thanks in advance

I've had good luck using the Smurf kernel with the battery spectrum profile on Havoc Oreo.
I'm going to upgrade to Havoc ? with Smurf's new ? kernel this weekend as the issue with screen off battery drain has supposedly been fixed.

According to Accubattery (awesome app BTW), I'm averaging about 10hrs (discharging 10%/hr) screen-on time and about 115hrs 35mins (discharging 0.9%/hr) screen-off time.

I should also mention that I use Greenify religiously. I also have it running as a privileged app (always root mode) via the Magisk module.

I can recommend Radioactive Kernel

Can't go wrong with any of them.
My personal experience says EX kernel, Blu(more battery focused), or Radioactive.
I use EX personally since I've had history with it before and trust it the most.
