Android System eating the battery

Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.

I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.

maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?

I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.

My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day

*facepalm* you guys don't get it....

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.

Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.

I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.

I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.

Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.

Desire battery observations

I know you guys might be tired of these threads but I thought I might as well post this.
My desire is fairly new(Less than a week) and so far its been good apart from(What I though) battery life. i've been trying to improve it and I think I might have "some" progress.
Currently I'm running DeFrost 4.9 with HAVS @ 1137(4.9a) kernel with the very latest radio, I also use only 2G networks(No 3G here). I got two Gmail accounts but only one has sync(The other one is merely for Google checkout CC purchases), I got one Facebook account set to sync every hour as well as LP Facebook widget also set to sync every hour. I also got FancyWidget syncing weather every 3 hours. Apart from these I got Nimbuzz running 24/7 in background. The battery is calibrated and yesterday I did a complete discharge/recharge.
Now I plugged it off the charger 2 hours ago, it was at 100 according to spare parts. The brightness is at 2%. I did some lite browsing, browsed a bit with Tapatalk Pro and 40 minutes ago went to a market nearby. During my trip to market I had Google Navigation turned on navigating me(During both, the trip to the market and return). Now while making this post the battery is at 81%. Does it sound right?

How much time the display was on? How much time was the GPS on?

Be careful, don't be happy before time. I did the recalibration too, and found that my phone would turn itself off at ~20% remaining battery.

During the navigation, about 5 minutes for display, 40 minutes GPS during which I went into a building for 10 minutes and it probably lost signal then.

OK, this ain't good. I slept at around 2 AM with 29% battery life. In the morning(10:30 AM) it was dead(0% battery).

Sound about right. 8.5 hours with your facebook and other syncs. I don't see any problems at all. Mine does this too.

First, in the night put the phone in airplane mode (I dont think u need to check ur facebook )
Second, check if u have useless programs that are using cpu in background, if is this the case UNINSTALL that program and CONTACT the developer. We dont need to kill those kinds of app, we just have to UNINSTALL if an app doesn't work properly, untill the developer will fix it. If all people will do like me, the market will full of great apps

I don't think I have any useless stuff running in the background. All I got are 2 widgets(Facebook and Twitter) syncing every 1 hour and 3 hours respectively, one Fancy Widget fetching weather and Gmail push for one account. Is their a way I can check all the services running in the BG?
EDIT : Forgot to mention Nimbuzz running 24/7.

Agree... before I used to see 1% but after "calibration" now it shuts down itself at 8~9%

I won't rehash all of what has been heavily discussed by now in much greater depth, like in the FroYo Battery Usage thread. But auto sync with such social applications and you set yourself up for low battery runtime to begin with. Especially with a constant polling IM and/or battery widget running too. Don't expect much.
Anyway, I don't use them but weather, stocks, 5 mail accounts and news is set to auto-sync every 15 minutes and WiFi is always running if available. Last discharge as soon as I connected charger ended at:
http://bit.ly/c6R59G
http://bit.ly/bmM9oN
http://bit.ly/cMlnun
http://bit.ly/akPvr7
I slept twice for 7-8 hours each on that charge and it includes all of my daily usage including listening to 127 minutes of MP3 via headphones with the screen off.

Hmm Wi-Fi + Nimbuzz really screws up the battery . Last night I turned off the Wi-Fi and slept for 8 hours. I had 46% battery before and in the morning I had 40%. I also have disabled Auto-sync for Twitter/Facebook widget and Facebook app. Now the only running services I got are Gmail push, FancyWidget weather and Nimbuzz.

How did you manage to get such good battery life? Your phone lasted for over a 32 hours period which included 6 hours of display. And that too with stocks and News syncing every 15 minutes. Does Nimbuzz really screw you that much?

Well now datz some good battery. Which ROM are you using? Which Radio are you using?
I don't have any account/social networking syncing. Don't use wifi more than 20 mins a day. Brightness 20%. NO GPS. No Bluetooth. No stupid application sucking battery's power. If my screen is off I lose about 3-4% for a period of 5 hours, so no app sucking the battery in the sleep mode.
If i use EDGE when the battery is Full for about an hour I get battery drain of 20%
Would love to know more details on which ROM, Radio and your settings.

OK. There's not much I can say except what other guys who know better than me said here http://forum.xda-developers.com/showthread.php?t=743172
It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

In contrast, I lose 1-2% over 8-10hours in standby, maximum, with WiFi on. Usually 1%.

Thats some damn battery life you have there. You are on a Sense ROM? Do you actually use Sense? If so you're either exaggerating or I'm a total fool(I'd prefer the latter).
I've been trying to fine tune the battery, currently I'm using DeFroST 4.9 with SVS 998Mhz @ 1275mv kernel with 17_2 radio. Re-calibrated the battery yesterday and compiled a custom wi-fi module containing fixes for sleep disconnection today morning.
I left it at night around 3 AM with 99% battery, turned off the Wi-Fi/EDGE but kept mobile on. In the morning(Around 9:30AM) I was at around 91%. Gave it a quick charge to 100 till around 11:15 AM. Disconnected it and from 11:20 to about 11:40/45 AM I had quite a heavy chat session over Nimbuzz with my friend. My battery went from 100 to 94% in that time. After that I pretty much left it, picked it up to check a mail once or twice and sent a few messages over Nimbuzz. It is 1:40AM now and I'm down to 89%. All of this was over Wi-Fi, GPS off, Bluetooth off, no tethering no nothing. I got no Facebook/Twitter auto-sync. Only FancyWidget(every 3 hours) and Gmail Push. Brightness is at 2%(Although even then it is a bit bright, maybe it is just me).
I am using Extended control widget to see the power percentage.

Whoa ! Amazing post there. This should keep me occupied for quite some time to figure out what the heck is going on with my battery. The battery life what you are getting is really good and that is what everybody should get provided they figure out what the heck is sucking their battery that bad. Lotsa things and apps you have said drains the battery is on my phone and I haven't even started looking at logs in detail. Itz been only couple of weeks since I have this phone so I'll defn start looking into this issue.
Few questions
1. What issues did you have with your build.prop?
2. What battery widget are your currently using ?
3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ? Would be great if you could link us to the location mod

OK, It is 7:05 PM now and I am down to 70%. Nimbuzz was on all the time along with Wi-Fi(Although I don't know what happened but it switched to EDGE as if it lost Wi-Fi connectivity, Wi-Fi wasn't disabled, just disconnected). And I pretty much haven't touched it since 1:40 PM. Not as good as I hoped, but still kind of decent.
And my Wi-Fi strength isn't that great either, it is either 1 or 2 bar out of 4.

Well, I haven't done any such kernel modifications intentionally. Never had any need to either. 14.5h since last charge now, cell on 5h, WiFi on 12.5h, display on 2h and 76% remaining (actually, those stats were collected and written an hour back). The Desire display has been verified to consume at least 70% of the total device power when the screen is on. So you can't get more hours with display on if it didn't run as such.
It's HTCs ROM so of course it is using Sense. I can't do without most HTC added goods in Sense. Let alone the Mail, Bookmarks, Calendar, Stocks, Copy/Paste, Lookup, Clock, Gallery and Camera apps and widgets. The widgets I depend on work well only on the HTC ROMs I've tried. The missed Sense goodness combined with the bugs and problems I had on AOSP ROMs were extremely problematic so I moved back. Even my video recording and native playback is much better on this ROM.
To be frank, you've hardly had the phone so you'll learn much more yet. And it comes through search->reading->experimenting first. 1-2 weeks is too little for even figuring out most of the basics, unless you're moving from a similar phone and OS. For one, you'll need to actually read the linked thread to see what many observed and experienced. It took me and many others 6 months to learn things and get to this stage. Every other day I was testing and monitoring. But be aware that you can't, for instance, have the exact same setup and usage as me to have the same resultant battery life.
Had you read the linked thread you'd also be aware by now that bugs were filed for inaccurate % readings by Androids Battery Usage section. However, its time tracking was reliable in my testing.
- On your typical full discharge, how much time and % is listed under Display on?
- And for cell?
- Which A2SD are you using?
- Static wallpaper/color?
- Animation settings?
- Location on?
- Network location errors in logcat?
- Cell network chosen auto or manual?
- Did you mention all the widgets on all homescreens?
- OSMonitor/CurrentWidget values in idle screen on and idle screen off?
I use EC and SwitchPro widgets too but their battery widgets (like you mentioned) are known as ones with high consistent drain. The EC dev also corroborated this in its thread under the Themes section.
The 'idle' drops you get don't make sense to me unless there's fundamental hardware/software activity you haven't properly monitored and logged. Even kernel and I/O usage in the background. You'd be surprised at the difference one buggy underlying feature can make.

If you're actually asking those questions, here goes. Note, I am at 66% and the time is 8:56PM. And after this I'm gonna nandroid this ROM and try SuperVillainHD just for the kicks. Also, can it be that since the phone is relatively new, the battery is not up to its full potential?
Q1, 2) Battery usage is :
Display: 35% (35m 37s)
Wi-Fi: 20% (9h 44m 22s)
Cell standby : 15% (9h 44m 22s)
Phone idle: 14% (9h 9m 42s)
Android system: 6% (CPU Total: 9m 35s, CPU Foreground: 27s, Data sent: 7.82KB, Date received: 11.38KB)
Nimbuzz: 4% (CPU Total: 6m 46s, CPU Foreground: 2m 54s, Data sent: 298KB, Data received: 851KB)
Android OS: 3% (4m 1s)
Voice calls: 2% (45s)
Q3) I'm using DeFroST ROM with A2SD+
Q4) Yes, I'm using a static wallpaper
Q5) Animations is set to : All animations
Q6) GPS is disabled, if that is what you mean.
Q7) How can I check this and what would it show?
Q8) Didn't touch this, so I'm presuming Auto.
Q9) I'm not sure, so here goes. I got a Twitter widget, Facebook widget, both are set for manual syncing. Got FancyWidget syncing every 3 hours and several harmless icons. I got 3 bars of Extended Control widget and a google search widget
Q10) I don't have those, are they available in market? Do they consume battery?

I'll have to open the file for that to check exactly the changes I made. I didn't really follow anyone, just went off my own understanding and intuition. If I try to access the dir or open the file whilst the phone is not in Recovery, it'll force a reboot so I'll give more details later on this when I'm near a PC.
2. What battery widget are your currently using ?

3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ?

FroYos A2SD was nice but I needed much more space and was trying A2SD+ with various ROMs as well as manual use on HTC ROMs. Endless problems such as very remarked, consistent sluggishness in basic functioning, total boot and app load slowness, including high, persistent background CPU and IO loads and very poor SD card transfers over USB and WiFi made me sack it. I lost a class 4 16GB Kingston SD card with errors inside 2 months. I transfer 2-4GB in/out daily and many transfers started failing. Widgets bugged out frequently when you needed them most and had to be all re-setup. Video record and playback became dis-able. The phone became useless except as a toy. That's not what I bought it for but as a helpful companion. I eliminated everything in question. It was simply the SD card [over]use compared to internal memory.

Even though I used this, I still have select applications not on the SD card upon learning that they worked far more consistently and properly with lower power and CPU usage when using internal memory. Trial, observant monitoring, and error.

My phone state running android

Hy everione ii decided to make a thread about my kaiser android porting state
i currently use sccoters cyanongen mod 6 with sys and data on nand im using his kernle just changed the panel type from 2 to 3 and now i have no more screen issues
The speed is preety good for an 2007 phone
The apps that i mainly use
Advanced task killer - a very helpful program when you have only 30 mb of ram
Astro-the best file manager my opinion
IM+ pro-a messenger ap
Shazam- a music recognition software
Thinkfree Office- a very slow office like app
Tunee Music pro- a music lybrary from where you can download free music
and offcourse xda app
Now i tryed fruity ninja but it runned pretty slow and everyone know the ,,awsome,, touch screen of these devices
Anyway curently i experienced some big issues
The wireles connection is somehow dropping i mean it dosent dissconect but the apps just lose it soethimes
My 1st issue the battery i cant chcarge the phone correctly i and it last only 7 hours
I tryed shuting it down and charge it but it restart itself
I really need to resolve the charging thing because its my prymari phone and i dont have other
I`m searching for faster experience and an working chargin tehnic )
Please excuse my english

Hi Cos:
Patience is all you need with the battery issue. If the kernel was written correctly for the phone, then the battery level will pick up and adjust. Any time I do a fresh install I have to wait for the phone to almost die before charging because battery level is always at 15% after install.
Wait for the phone to be about dead (look at "battery information" under Spare Parts. You will see the battery voltage listed in millivolts (shown as mV). As long as that voltage doesn't drop below 3500mV, you'll be fine. Once it does, charge it from that point on. It "should" pick up on the low and high battery voltages pretty well after this.
High volt reading is around 4150, lowest should be no less than 3500. If the battery never reaches 4150-4200, the battery is bad and should be replaced.

No problem here
My Kaiser "Android powered" last for 2 days - sometimes more.
"atools > Battery Capacity > Advanced Settings > 3200"
A have standard 1350 battery
PS: NAND install and no suden drops in battery level

lag on motorola defy!

my defy is just 2 weeks old and i have started experiencing trememdous lags....
its 2.2.2 running , kernel is 2.6.32.9-g0671d13 , just in case it could help in finding a solution...
1. the screen goes off on its own half of the time (even though the time out is of 1 minute) and even when i unlock it , it again goes off.. ITS REALLY FRUSTRATING
2. i have just 1 game installed, but even then the phone lags a lot, the game lags and so does the entire phone..!
3. the internet isnt getting activated (i guess thats a network problem though), anyone with a similar problem!?
please post replies as soon as possible..

well i too experience the same, mine is 30 days old...
I have disabled gps/data/wifi/auto brightness to get max battery yet it fails to go beyond 1 day even if i use max an hour of wifi.
screen going blank on it own is frustrating
moto widget for time and date does not keep current time
lag in touch even after running ATK on auto aggressive mode
defy is running indian 2.2.2
p.s. any idea if i can get data on first date of use for battery? I somehow feel a new one should give more standby life.

my phone does last around 1 1/2 days with an hours gaming....and it does keep the current date and time (as of now)...
mine too lags inspite of the ATK being on autokill.... even the homescreen takes time to load after pressing the home button ...

Might want to try getting rid of ATK.
Tasks/services run for a reason on android. When something kills them, they'll start back up, causing more cpu and memory usage than if you'd just leave the service running.

Run for a reason, but not necessarily a good one. Stock motorola/vodafone firmware that I had on my defy would run many completely irrelevant processes - VF360, newsandweather, amazon mp3, etc. Task killing isn't the solution because they just start up again.
The best way to get best performance from the phone is to install CM7.

You could try to wipe in stock recovery. Check http://forum.xda-developers.com/showthread.php?t=1216982, point witch says Froyo laggy. You will lose all data.
If you find it laggy afterwards, you will never be happy with the preferments on stock froyo. Then try CM7. You will be able to downgrade to send it to warranty as I also did this. It is quite a difference.

Is it going off while you are holding it by the top, with a finger on the left of the speaker hole?
If it is the case, it is because you are masking the proximity sensor. And if you have the "Pocket detection" feature activated, it will cause this annoying stuff...

Well not to worry even mine was laggy before, i had just installed 2-3 apps. I had to restart my phone at least once then i installed cm7 rc1.5 Now its very fast and i dont remember the last time when my phone was lagging and freezing.
I guess it has something to do with the froyo and motoblur on defy that makes it laggy.
You have to have get rid of stock froyo after owning a defy.. thats the truth..

I did a readup on the ATK stuff and the excerpt from the and dev documents... well since the read i have uninstalled all task killers... (kept one just in case with all auto actions disabled)
I do hope the lag issue is resolved after moving to CM7/Jboogie3 etc
however the battery issue is a major hurdle for now as one day is too less, i probably have to take it to the service center for a checkup and/or claim warranty on battery. till them no flashing for me...
att: patriiice - even when the proximity sensor is not covered, i do experience screen blanks, almost immediately asa the power button is pressed to wake the device.

The lag presented on the Defys running Froyo is a "super nice feature" by Motorola it has an easy fix tho.
Its caused by the VM consuming all memory, all its needed is adjusting the amount of MB the VM should leave free.
There are a few ways to it:
1) Run a terminal emulator, or use GScript Lite to run this:
su
vm.min_free_kbytes=8192
(Not permanent, need to be ran every time you reboot)
2) Get Sysctl from market and do it from there.
3) Get SetVSel and do it from there.

Lag
I have that problem to. The bad thing is that i can`t answer call during the lag, it says i have my phone is closed or i don`t have signal. I`ve installed Temp+CPU and during lag it shows that the proc is running at 100%. Memory has all the time, around 130 min and 230 max. Closed all programs one by one, no change. I restart the phone and everything is running smooth and it lasts max 1 day. i have stock rom 2.2.2. (please excuse my spelling)

I also use 2.2.2 stock and my defy runs without lag... you should consider to root the phone and freeze some unnecessary stock-preinstalled apps like Kindle, Voice command, etc... the ones you will never use. I freezed about 20 apps and there is no lag at all. (I even froze Maps, Streets, SIM toolkit, and some others)

My Defy was lagging until I rooted and installed SetVSel. Now its running as breeze with Stock Indian Froyo.

stock froyo is not good but it shouldn't be that bad. there were some faulty battery issue that i have heard of before too. but in your case your defy might even be faulty. so i would suggest you get it replaced or fixed under warranty first before flashing any custom rom.

lag on defy
with rootunistaller i`ve frozen skype and yahoo and i haven`t had any lag since. If i want 2 use them "defrost" and when i`m finished i just "freeze" back the app

Nope. I was wrong after 3 days of normal proc usage it started again. I`ve installed OS Monitor (free on market) and there was a process the ate all my resources: "DRM Protected Content Storage". Selected watch log and there was something like "enter,delete update, uri: content://media/external/audio/media/1 ../44.... /254..."
This process is searching ur phone for media, video audio and looked like it was stucked at this folder. I`ve searched the phone for that folder but couldn't find it so i just killed the app in OS Monitor. After the process restarted at log was showing "media search finished:182 audio files found and 1 video found". Looks like that's my problem and maybe yours to. Cheers mates

so I might visit the service center this weekend to have my battery life checked.. one day life with all wifi/data/gps disabled and below average voice calls is not acceptable at all.

what is stock recovery?? and will it void my warranty???

thanks a lot guys for ur replies!!
but the thing is my phone has become even slower!!
when i first switch on the phone i have around 240MB free RAM but just after an hour everything becomes too slow, even opening of the menu! and after 2-3 hours of usage it keeps on reducing and finally reaches as low as 40MB .....
what could be causing this??
i have android assistant by which i clear cache, ram still it doesnt help....

Making the most (batt) out of sgs2-tmo

Hi all,
This is my 2nd droid, first was the awesome dezire-z and now this.
Since cyanogenmod for this is not official, which is my favourite to make 2 days out of these post nokia smartphones, I thaught i'd play a bit with it.
Just fyi, I like having a phone that gives me a 2 day (morning to night, 36-40 hrs) battery with moderate use. When I had those goodo'l nokia n/e series, I never had to worry about charging...
Anyways, if you want to try this, here's what you need:
Root (ofcourse),
Titanium backup,
Ram manager,
Set cpu,
Log watcher,
Juice Defender,
Patience (a lot)
My set cpu is @1026mhz-192mhz, conservative, (adv) up%-75, down% 25, freq step - 5
Screen off - 432-192mhz, conservative highest priority
Batt <30% - 702-192mhz conservative
Charger ac - 1512-192mhz, on demand lowest priority
Ram manager - balanced multitasking
Titanium backup - frozen almost everything I don't use. I freeze some, use it for couple of days, monitoring with log watcher if I see any fc and defrost apps accordingly.
Frozen - accuweather, allShare, Ap mobile, Asphalt, Backup, Bilo, Bluetooth test, Bonus Apps, Calender, Customize Homescreen, Days, Digital Clock, Dual Clock, Email 3.*, Email 1.*, Home Screen test, IM 1.0, Kies Air, Kies wifi, kobo, Media hub, microbes, mini paper, more for me, My account 2.*, photo editor, polaris office, pro apps, Slacker, SNS*, Social Hub*, T-Mobile*, Tags, TeleNav, Video chat, Voice Command, Yahoo finance, Zinio reader
Couple more packages are there, but its risky beyond this point.
Juice Defender ultimate - advance, mobile data, bluetooth and wifi enabled, wifi preferred, autosync - ping, bt disable timoout - 5 min, bt enable on call, added my bose bt1 as configured devices, Screen - enable connectivity when screen is on, traffic - enabled, apps - disabled, location - enabled
If anybody can suggest other utils/pieces that may be useful to squize out batt life, please let me know.
Finally, thanks for this forum. This was and still is the most helpful for any of my droid queries.

Yeah, that's the pitfall of a smartphone. Check out Juice Defender. The free version's helpfulness is debatable, but the pay version is quite beneficial. Instead of freezing apps (which might be overkill, especially if you ever want to use the one's that are frozen), you can disable each app's connectivity with regard to behavior. It also manages 3G/wifi connectivity pretty nicely and has various profiles which can be set up to manage battery life.
Good luck!

Good topic - thanks.
As an old-time BlackBerry user recently converted to SG2 - I'm getting ready to break-in the new phone on its first trip (ie MUST NOT FRICKEN' FAIL).
Getting at least a good 18hours of battery time helps...

How many hours of use would you consider moderate use within the 40 hour period?
Personally I've noticed the battery will last up to 4 to 5 hours of display time on stock and its more or less the same with any Rom or clock I use. Seeing how I don't use the phone for a constant 5 hours the total battery life varies on what I'm doing that day.

My SG2 shows 5h42m of full-time use (via Battery Monitor).
Battery Stats estimate 7h30min full time "Talk" - doesn't make sense... so I'm not reading the estimates correctly.
A single charge typically lasts about 18hours (takes it down to around 15-20%) at my office.
Just recently noticed that "AdFree" seems to have spiked my SG2 battery usage - I'm sure as a side-effect to re-directing adware to localhost (ie adware panic). Didn't see same effect on Xoom tablet.

I can agree with everything here (thanks for posting) except the RAM Manager. It's generally accepted modern android devices don't need extra applications to manage running applications or RAM usage. Has there been evidence to prove otherwise?

It's true. It is better to let Android take care of memory management and often extra RAM is bad since Android is dependent on using up free memory for a better user experience.
More on HERE.

Keep in mind, reading ram is a LOT less battery intensive than reading off nand. So when you're constantly killing active apps in ram, and then re-loading them later, you're actually hurting battery life.
If you want REAL battery savings, you should be paying attention to what is running at startup on your phone. You'd be amazed how many apps, hell even live wallpapers, run when they aren't being used. I'd suggest using system tuner, going into the startup tab, and removing anything that doesn't need to run at startup. Short of email programs, mms, and anything you want syncing in the background, I'd uncheck all other user apps you installed. They'll be put into memory then only when you actually use them, and save battery power.

Why underclock 33%? Seems pretty extreme. Just use Juicedefender as aforementioned; makes it sip on stand-by.

also, my theory is, i don't do anything that requires 1.5ghz clock cycle plus 2 cores. So if i'm on netflix on my mob, i just plug in the charger - therefore full 1.5 ghz is available.
This h/w is overkill per my opinion, i'd say its future proof for at least android 5, BBM (blue berry muffin)

There's a nasty kernel hack to do the same, buying the app is just easier, but thats just me.
I personally felt after all the throttling I did, this is the one tweak that makes the device snappy. After all there's so much ram to spare, this app tweaks the preloading I think. I can feel the difference when I clear memory and the snappyness just disappears.
