Hi,
If you want to know how long your battery life will last when:
- Idle on 2G/EDGE
- Idle on 3G
- Idle on WiFi
- Browsing on EDGE/3G/WiFi
- etc.
What cost battery life the most?
You will learn that "waking up app for doing nothing" will cost you heavily on battery life.
Things like checking email while you have no new email, checking weather while you got the same result, or getting data online while you are not connected to the network.
And so on ...
Sit tight and watch this:
http://code.google.com/events/io/2009/sessions/CodingLifeBatteryLife.html
This special session from Google IO in the past CupCake era explained in detail, with measurements about almost every aspects of the phone that drain the battery.
Interesting enough that IDLE on 2G vs IDLE on 3G will cost you almost the same. And browsing in 3G is more efficient. So, in this respect, I think it is not necessary to set to 2G as most people said for auto-syncing.
At home, use WiFi, because it is more efficient for web browsing.
Choosing and planning your sync and widget will make big different on battery life!
Watch it your-self and share your thought.
i've just removed advanced task killer app, and seriously battery lif is like amazing normally by now i would be at around 50% i'm at 70% and have been using it more like 2 phone calls i normally don't make any and a tiny bit of browsing but that certainly improved it

So your saying advanced task killer is draining battery? Even when its not running ni the background. It can kill itself along with killing apps, so it shoul dnot constitute ANY drain on the battery when not running in the background.
Here what I experienced:
First of all, my phone settings:
- WiFi OFF (on when needed)
- Mobile network OFF (on when needed)
- Always on OFF
- Background data ON
- Auto sync OFF
- GPS OFF
- Bluetooth OFF
- 10% brightness (yes, my eyes is happy with that, seriously!)
- Using HTC "black" wallpaper
One day, I played around with killing tasks, not brutally killing, but just some of them like RADIO, MARKET, etc. Selectively killing.
Then I watched my battery usage, it drain quite a bit like 3% after 1 or 2 hours. I meant, it was really different compared to the other day when I did not touch task killer.
Today, I unplugged at 8:00 AM ... 100%
Now, 15:00 ... still 98% (after 7 hours!).
During that time, I played around a bit with Market via WiFi and SMS, no phone call.
Seriously, I got different result when using and not using task killer.

yep plus i'd normally i don't have bluetooth and i forgot to turn it off today afer using my blutooth headphones, and still at 70% yeasterday it would have been dead by now and i didn't even use task killer to kill apps. maybe advanced task killer stops apps being killed by the android system.

I find this one a strange (what seems to be) fallacy when coming to Android 2.x. When I got my Desire, the first thing I got was a task killer. Then, a widget to let me know hom much RAM I have left. When it got low, I used the TK to do it's job and free up some RAM.
But the permeating fallacy seems to be that a TK is needed. But it seems people are finding out, time and time again that it's not. And as people here are finding, it's detrimental. And after not using my TK for a while, I found out that though the RAM can get low, Android will do it's thing in the background and I never notice low RAM in my daily operation.
Some people on another forum put me onto some info sources that explained why TKs can make your battery life shorter. In short, they can kill tasks which have scripts that will respawn, thus causing higher CPU usage and draining battery a little bit quicker.
There were other reasons but I can't remember them right now. People should really let people know and educate them (including some popular websites like AndroidCentral.com that I like) that it's not necesary and actually a waste. (Though I use mine for doing things like file management, installing and uninstalling, but not task killing.)
I watched most of that video that was kindly posted. And if I get this correctly (please correct me if I haven't), when I'm in wifi range, I'd be better off leaving that on to do data transfer as there is a negligable passive battery consumption over 3G and 2G, but a saving when transfering data which grows as the data transfer grows.
But then wifi should be turned off when leaving the wifi area, as like 3G, it drains the battery to have it searching.
Since I'll be in a wifi zone for most of tomorrow, I'm curious if I can get through a full day with wifi left on...
what makes me wonder is if i go to the market, search for something then i go to browser for couple minutes and then go back to the home screen, will the market and browser use the 3g/h/g in the background?
sorry if the answer for this is in the video but do not have time to watch it right now.
It's been said many times that Task killers are not necessary on Android phones and that their use will almost always result in worse battery life and reduced performance.
I used to have two HTC Heros and proved pretty conclusively that the above was true by running a task killer on one but having the same apps. on both. I even reversed things in case the battery was better on one of the devices.
You will never convince some people though. It they want worse battery life and performance surely that is their choice.
I know I will never again put a task killer on an Android device.
Hey guys, thought it might be a good idea to share with each other what apps/settings are mauling their battery life...
Personally at the advice of beards, I used systempanel app to try and monitor app cpu usage etc.
I was experiencing large battery drain overnight, so I decided to leave it running for 1 night. By the morning I had lost about 30 or 40% of battery and systempanel told me that Fancy Widget was using about 11 or 12% avg of cpu (if I remember correctly).
I removed Fancy Widget, turned off Data (with APNswitch) and also stopped systempanel (which prob contributed some of the usage itself) when I went to sleep the other night and the batt was at 40% usage. In the morning I turned on my phone and was greatly surprised to learn that the phone was STILL AT 40%... didn't even lose 1% wooooot
So.. I'd like to put my suggestions out
Batt hungry apps: FancyWidget (maybe...? but I'm surprised that other people don't seem to have a problem so maybe its my human error?)
Phone settings:
Data:3G data seems to consumes a lot!!!
I suggest leaving on 2G if you want to keep auto syncing apps etc, and swapping to 3G when you really need the speed (browsing/downloading).
If you want to totally maximise battery usage, turn off data completely every time you put the phone on standby, and turn off all autosyncing apps.
I also believe Wifi consumes less battery than 3G usage, although I haven't done any serious testing, I managed to use wifi on and off for about 5 hours at a lanning event and I still had a fair bit of batt left.
Recommended apps:
I recommend APNswitch to turn off data. I like it because you can use it as an app, not just a widget, as I've found all the APN widgets too be ugly. It also uses the notification bar wisely
Other experiences:
According to systempanel, samsung widgets (feed, buddies, daily briefing) all consume very little CPU (less than other widgets in my experience. I've kept them all as they seem beautiful to me
To XDA members, anyone else experience bad batt life with fancy widget?
Please feel free to critisize any of my claims, I hope we can help each other out with sharing battery life tips, good/bad apps etc.
EDIT:
Wallpapers:(thanks gadjet0)
Live wallpapers seem to consume a lot. Also having read discussion about the power consumption of oleds, I put a pure black background on my device. Whether it's actually reducing power or not I have no scientific evidence.
Thanks should pin this!

Have you tried any live wallpaper, I got the feeling that they put a drain on the battery!
Yes, all its true what have writed oswade. I was make this thing with my Galaxy, and battery life have very growing...
Regards
also try tasker, I have set profiles to put phone into airplane mode at night, during day the data is off, but comes on every 15 mins or when the screen is turned on (like juicedefender i think its called) works brilliantly and conserves battery.
I can unlpug phone at 5am and still have around 60% at 9pm with light usage, while before I would get to evening and battery would be close to dead!
Glad that I'm not the only ones.. I suffered quite bad. Full charge ard 6pm..was playing robo zone for an 1hr+. Batt left 50%. Arghh..
Does black or darker background uses more batt?
I'm using beautiful widget.

Couldn't figure that out either... probably need to use a task-killer or reboot.
So what do you recommand (or anybody else) to replace Fancy Widget ?
I don't really want a HTC like Clock but I want a digital clock like this ?
Beautiful Widget for exemple ?
And i don't know why an app which automatically turn on/off the 3G when ur using the brownser/market doesn't exist already ? That will be great !!!
What's wrong with fancywidget? Seems fine on my device.
If using Juicedefender,do I still need Advanced Task Killer?
Then What?
Hi!
We have industry best hardware configuration.
But we
1) can not Use live wallpapers
2) can not Use 3G for many hours
3) can not Use considerable number of applications from the market
4) can not watch two full length movies
5) etc.................
If you want above
1) Purchase additional battery and put in your pocket
2) Power adapter/ Travel adapter always carry with u
If you are roaming for more than six hours, then it's bad.
this is not only for Galaxy S most of the samart phones fall in this.
What can we do????????

Dude, I have a Samsung Galaxy Ace
As soon as I got it I installed fancy widget and some other programs. My phone was lasting only 6 hours. I sync to corporate, gmail, facebook and a few others. At first I thought 'bad phone'. I uninstalled Fancy Widget last night and voila my phone is fine. It'll last a day+ now.
What the hell is wrong with that app?? Why does it need so much compute? Its just a widget that shows time??
I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.
If your getting great battery life, help me and others by sharing your tips here.

Best tip is to stay on wifi as much as possible. I got 3 days on wifi and about 4 hours use.

I turn data off when im not using the internet and when I'm just listening to musc I just put my phone in airplane mode
Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).
i ran these through my seat-of-the-pants benchmarks, are there any other for these sorts of apps? , and can't tell any difference. the biggest difference maker that i have noticed is Titanium backup and freezing as many progs as i could and a better launcher.
i tested the phone as it initially came out of the box, removing the apps i could via app manager.
next, i ran it with JDU for ~4 days.
Then i ran Tit backup and froze many more apps and ran the phone with JD for 3-4 days.
then installed Ram Manager Pro and ran for a few days, then uninstalled JD and Ram Manager by itself for a few days
and finally uninstalled both, factory reset my phone, ran Tit Backup freezing everything i wanted and am now running that config for several days.
i can't see any change in battery life or perf between any of these.
what's your experience? did i miss the benefits? is there a more scientific way to test these apps on our phone?
I could be missing something, but my understanding of Ram Manager is that it controls how the cache works (RAM cache that is), aka, how previously opened apps are being handled, how long they stay in ram, or/and how often ram getting cleanup, etc. So theoretically there shouldn't be much of battery improvement with that app, only the performance on common used tasks.
As of Juice Defender, I've tried once, and realized it's not for me, I use push mail and listen pandora radio most of the time, it requires internet all the time. But in theory it should significantly save on battery if you don't use phone every second minute, cause it turns off everything and only turns data one every so often to check email, news, etc.
I guess it depends how you use your phone...
Have you tried SetCPU or such?
I use SetCPU to change CPU frequency, set min to 190mhz and max to 1500mhz, and max to 190 when screen off, yesterday with minimum phone usage in 7 hours used up 15%
And I wonder, by default, does Nitro set CPU to max and keep it that way or it also uses scheduling and changes speed as needed?
But I can tell you for sure, the network (HSPA+ here) usage uses as much battery as the screen, if not more...and network through WiFi saves on battery compare to HSPA.

that's my understanding of Ram Manager as well. but i didn't notice any perf changes in how fast apps open, close or switch v a Titannium freezing showing good results imo for that sort of thing.
i listen to slacker/pandora but it's mostly via wi-fi, so i was able to configure JD to keep the wifi on and turn off all the other radios but that didn't seem to provide me any benefits.
i have not tried setcpu but will def check it out, thx for the heads-up on that one.
re: network, it doesn't even show as a battery drain on this phone and i am in an LTE area, the 4glte status signal is always on. i was under the impression it was a massive drain, maybe the phone searching for a lte signal is the drain but once it finds one and locks on maybe it settles down. i have no idea but it's not on the list of what's using the battery.
Ram Manager Pro has several settings (Balanced, Balanced-More Mem, Hardcore Gaming, etc...). Did you try any of the others? For me I noticed improvement, but perhaps it's also because of the way I use my phone and that Ram Manager is more suited to my ways and habits... Or maybe it's just placebo and I'm drinking the kool-aid.
For Juice Defender Ultimate, I will say probably one of its' biggest capabilities is locking down the apps that turn on the radio for background updates. A definite battery drain for folks that use a lot of social apps as they compound the use of background updates. I personally turn-off ALL background updates except for mail. So JDU wouldn't tremendously help me.
Lastly, I completely agree with [email protected] about SetCPU. I don't know how the OS handles the frequencies but one of the biggest battery savers is definitely using SetCPU for dropping the min/max CPU speeds to minimum levels when the phone is sleeping.
I installed setCPU and it instantly created a laggy interface. very very noticeable. HAs anybody else tried this app with this phone?
Had this same problem. I actually switched of all apps. The phone on idle does not loose that much juice. Overnight I maybe loose 8-10%. I turn data off at night using Tasker.

I've still been farting around with these apps, going back & forth between using them and not.
best I can tell ROM manager provides ~5% increase in ROM management, which is pretty good for a couple bucks eh.
JD is so much harder to gauge/compare. I think it does defend the juice but I can't tell how much. The one thing I do not get about the app is how it continues to show increased battery savings over the previous 48 hours. I can see how this works when the app is 1st installed but at some point over time that number should = 1 right? JD can't keep stretching battery life 1.5x over its own management system.
scott0,
You're right, unless there's some heuristics built in (probably not).

Anyone using a good stats widget that would show mhz of cpu/baterry/ram?
Something light that would not eat battery. I used the one that came with antutu cpu master but that caused more problems.

Just out of curiosity, do you have to be rooted to use Juice Defender? When I select the app in the market it tells me "This item isn't available by your carrier."
Are they telling me that AT&T has blocked a power saving app?
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.

I have juice defender, but I have a (probably idiotic) question. Does the juice defender icon have to be up on the top for it to be working?

Somewhere in the settings, you can set it not to display the icon when it's running.

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.
