Screen Brightness
For 99% of users, the display is the #1 consumer of battery, which makes sense because you have a giant 4.65 inch 720p display that needs lots of power to run. The lower you set your brightness, the more battery you save. For a person like me, 50% brightness is usually the highest I use. Colors look clear, the screen is plenty bright to read, and yet it's not too high. If you want to save battery however, turn down the brightness to around 30%. If you're really in a pinch and need to save some juice, you can even turn it down all the way to 0%, but I would recommend keeping it around the 30-35% mark for general usage. In my experience, standard auto brightness doesn't work too well for me. It's slow to respond and either cranks the brightness way up or way down inappropriately. However, some ROMs like CM10 allow you to modify the backlight settings, which works quite well.
Maps/Latitude
This tip is a little more straightforward. If you use Google Now, you are using Maps location services which drain battery. It's always looking for your location to give you the latest weather, let you know about the cool sushi restaurant down the street, and other neat stuff. However, it needs to know where you are, so it's constantly polling the network for location data. So, shut off Google Now completely, or if you're like me and love it, just shut off the parts of it that you don't need, like Places and Traffic. I saved the big one for last. Latitude. The silent battery killer. If you're like me and you never use Latitude ever, guess what, it's probably still using your battery, so you need to shut it off. Simply open your Maps app, hit menu, then settings, then location settings, then disable location reporting and location history. Your battery drain should decrease significantly. I check this often because it seems to reenable on its own sometimes. Yikes.
Radios
WiFi is pretty fast at your house. Way better than 1 Bar of 3G. But when you leave, you leave the WiFi on, thinking it's no big deal. However, WiFi is one of the biggest battery killers, along with the other radios. So remember, just shut stuff off when you aren't using it. No navigation today? GPS goes off. Not using your headset? No bluetooth. Haven't invested in those fancy NFC tags? Shut that off, too. A big one is LTE. If you live in a 3G only area, what good is it to keep LTE on? It's just draining your battery. Turning Data off can save you money and battery. If you aren't one of the lucky ones still on an unlimited data plan, shutting data off will stop apps from using data in the background, and it'll also save a bunch of battery. However, you won't know when fnartsy123 liked your Instagram photo.
Apps
There are some apps that constantly use system resources and keep your device awake, even when you aren't using it. A major offender is Facebook. While a big update is rumored, the apps frankly sucks right now. It's slow and it drains your battery. Stick to the mobile website, as honestly, it works better now. That's the main one, but there are plenty of other. To identify them, I recommend an awesome app like Better Battery Stats or Appsucker from Google Play. They'll tell you what app is stealing your juice, and you know to remove it.
Auto Sync
One of the main reasons to own a smartphone is to stay connected, and I don't want to change that. I would recommend you shut off syncing for services and apps that you don't use. Check your Google account settings. You don't need or want all of your selfies to end up on Google+? Shut off instant upload. If you use Chrome instead of the AOSP browser, shut off sync for that. Go through and make sure you only are syncing what you actually use. Also, check your apps. Do you need to know when you have a new tweet? If so, leave it on. If not, shut it off. Furthermore, if your battery is in the red, shut off autosync altogether to save some serious juice.
Good tips, especially turning off google now, its useless and even worse its a huge battery hog.
Nice article mate. Very useful tips. Good job. :thumbup:

Great tips, but Id just like to make some additions:
Use Y5 to turn on/off wifi based on your location
Use Tasker to set a schedule to set auto-sync on for 2 minutes at 30 minute intervals.
nice guide, thanks
Just to let you know that you can keep the gps setting on. It only uses power if you are using the GPS. So yes if you have like google now checking for your location it will use power but if you don't have anything automatically using GPS then you can keep it on and it won't use battery.

I'm trying to figure out if it's worthwhile to turn off mobile data when the screen is off, and turn data back on when the screen is turned on. It would also be necessary for me to occasionally switch mobile data on even when the screen is off in order to check email. (I'm thinking something like 15 minutes off, 3 minutes on)
Does anybody have any success stories or advice whether I am likely to see any noticeable battery savings by doing this?
I started doing this from when I first got my evo. Just turn off mobile data, you can still get texts and make calls, and then turn it on when you need it. Also turning off background data in settings also adds additional battery, but just enable it when you need the market. I went most of all day with about 80% of my battery still good between it just being off, using the mobile data here and there, and some texting.
Edit: I don't use a tasker, I just use the power widget in my notification, so I can turn on my mobile data on/off with just a tap. And if you're like me you don't know when you actually need it or for how long. So I find it easier and more effective to do it manually.

X2, i use switch pro to toggle mine. Battery drops about 2% per hr while data is of with screen off even when listening to music from my play lists.
I turn off the "always on " mobile data and noticed a big difference. The data turns on and off with the screen.

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 7.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I am the owner of SuttCo. We developed the Locale Mobile Data Plugin (which can be used by Tasker). It has a condition that can keep tabs on your data use and a setting which can be used to shut off mobile data.
I know Tasker and Locale have screen off/on conditions. I don't have time to run any tests for you (busy working on a new plugin), but if you're willing to do a semi-scientific study and report the findings here... I'll comp you a copy of the plugin. Shoot me a PM.

Not to say that turning off mobile data when you're not using it is a bad idea but I've found during my own personal experience with trying to improve my battery life for daily use that using titanium backup to freeze Google Backup Transport.apk is also a helpful solution. Other things that helped are going into Accounts & Sync and turning off background data because believe it or not, that stuff eats your battery up like a fat kid eating cake...hahahaha...Anyways, another tip would be to hit up Display and turn off Automatic Brightness and play around with the scroll until you come to a setting where you can see because I've found that the Automatic brightness eats up your battery too, not as fast but it does! Another thing that I've done is this and although there are task killers that would do this for you....I've decided to do this myself and after using an app such as Facebook or the brand new CNN app, I've gone into Applications and force close them out just to save battery and all of this nonsense I'm talking about has helped me out alot......NOT TO BRAG but using these little tips of mine, I've gone from 2 and a half hours and I was at 70 percent to 4 hours, 36 minutes and 48 seconds and I'm at 68 percent.....and that's with out turning my phone off, that's talking on the phone, texting, checking my facebook, downloading some apps here and there and just leaving it on in front of me at my desk.
Please don't start posting "Oh what, you want a FUC%ing cookie now" and all of this....all I intend to do is help someone by sharing my story....that is all! I got to get my butt to working again...hahahahaha

I have setup a few Tasker profiles to do this exactly. I did this instead of JD because the free JD doesn't do exactly what I want it to do, and I don't want to pay for JD when I can emulate it with Tasker.
The only thing I cannot do, that JD can, is keep data on while there is an active connection. With JD, if you turn off the screen while there is an active data transfer, it will wait until the transfer finishes to turn off data.
According to the Tasker website, there is plans to make a state/event "connection data rate" which would make it possible to do this. But that has been in their plans for quite some time. (I actually happened upon this post while searching for a way to check if there is an active data connection with Tasker.)
Also, with the way that Tasker views an "Open program", the program has to be open in the foreground in order to be considered open. This makes it tough to keep data on when a specific program is open, unless you're planning on keeping that program in the foreground all the time. To get around this, I created a profile that leaves data enabled while I have headphones plugged in, since I have headphones plugged in while using all the programs that I want to have constant data with.
EDIT: here are the profiles, and the tasks that go with them (I also included a profile that turns off the wifi antenna after disconnecting from a wifi access point.)

I am running AOKP M3 with franco kernel #15.2, turtle governor, 350/1000 w/ stock franco voltages. I also modded the auto brightness levels to ones of the MID mod. I use WiFi at home; I have set the power saver to switch to 2G after 1m of screen off time. However, I an unable to get more than 2-2.5h of screen on time no matter what I try. I plan to purchase the extended battery, but in the meanwhile what can I do to improve the battery life? I have the GSM phone.
Thanks in advance!
I've tried all sorts of stuff and 2 and a half hours is the most i've been able to get.
In order to do that I was using mostly wifi, auto brightness and I had undervolted as much as possible.
I've tried all different kernels and i've just accepted the fact that with this phone and the way I use it that's as good as it's going to get. To be honest i'm satisfied with that because in order for me to get 2+ hours of screen on time it has to be my day off, otherwise i'm too busy.
Also, i'm pulling 14-16 hours per charge with 2-2.5 hours of screen on time which in my opinion is great. I just want it to last all day and for me it does.
Try LeanKernel.
I get at least 4 hours battery life with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1200 Conservative
UV: Stock
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Brightness: About 40-50%
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
Even without the extended battery like you I would at least get 3.5 hours.
#1- people getting over 3 hours of screen time are on wifi the whole time, have 4g off, are minimalists with no syncing and no voice calls, or a combination of any of these.
#2 - based on your graph you have a lot of wake locks. Look at how often your phone is awake when your screen is off. That is KILLING your battery life. Disable or uninstall rogue apps, and turn off GPS and location services seems to help with this. Also reduce your amount of sync intervals if you can.

Look at the betterbatterystats for wakelocks; looks like lookout kept half an hour, the rest are mostly sync.
Try to remove all widgets for a while. This can rule things out.

I only have the calendar, clock and palmary weather widges (6 hour auto update). As far as I can tell Lookout and Sync are the *****es - literally. But that doesn't solve the idle drain, with the phone sleeping, it seems like 2-3% every hour or something like that.
That doesn't sound right. I have everything running as well. I don't use lookout any longer though. I'm sure if I just did the idle test I can get over a day of on battery time and still reach nearly 5 hours of on screen time. That's mostly Wifi which is suppose to drain more battery life, but I haven't seen the difference from being on 3G. This is a good set up.

I think you should try removing lookout. Take for example my awake times when screen is off. I sync Gmail, photos,remember the milk, and beautiful widgets.
Also major battery awake drain in beginning of my graph is due to streaming Google music when screen was off so perfectly normal.
Sent from my Galaxy Nexus using XDA App
Alright, I will remove Lookout. What alternative do you recommend, in case someone pick pockets my phone? Preferably free or cheap w/ Internet access. I'm thinking of Cerberus, as it'll be impossible for any wanna be thief to remove; I suppose the 3 EUR license is for device, right? Does it persist through ROM flashes (i.e. based on IMEI).
As for WiFi drain, on 3G it would be worse - it's longer range thus it needs more power and if the signal is bad (lucky I get top notch at home, not so at school), it's even worse.
When I get some more cash I'll order the extended battery and a dock off eBay, then I'll have a large main battery and the original one as a reserve.
EDIT: I've added the stats for this day. Better overall, the phone was used more intensively so getting a bit higher screen on time is good. I disabled Google Talk, I see it keeping the phone awake for a significant time, but I never use it. I also get rid of Palmary Weather and switched to the built in app, I'll see tomorrow how it goes.
The screenshots on the original post show sharp increase in battery drain when there is a) screen on and b) no mobile network signal.
In my opinion, these are two if the biggest culprits. The screen is obviously a power hog, especially with max brightness, and the lack of a network signal forces the phone to increase power to the radio in order to find a stable connection.

Well with the screen there's nothing you can do; A big screen will use a lot of power, a dense screen with use a lot of power, both is even worse. If this were an LCD instead of OLED the battery life with Holo would be horrible. Turning the brightness even lower than my tuned auto levels is not an option - the phone would be impossible to use due to the glossy nature of glass. As for the network, I can't do anything about that - the school building is built from reinforced concrete, that sucks up the signal pretty well and it's downtown, where the signal is already quite shoddy; at home I have a celullar tower 1km away so I get excellent reception, not so downtown.
But I'm not complaining about those. I mean the background activity, mostly the idle wake time. I'll see what I get tomorrow now that I killed Lookout and Talk, those seemed to be two major hogs.
Seems like you have a lot of awake time. Try disabling Maps, Google+ and remove all widgets and test it for a day. If it is better now, you have ruled out signal problems.
Is there any way to reduce the interval of Google sync events? (gtalk_async_conn) When I was at home on WiFi I got a sync maybe once every few hours (seen as wake). As soon as I left and turned WiFi off the sync was like every 10 minutes, which is weird, as in the AOKP ROM Control power save settings I set it to PREFER WiFi.
Why do I get a LOT more sync wakelocks on mobile data than on WiFi when the ROM is set to prefer WiFi syncs?
best pattery save I have found is turning off various radios
I use an app Profile that can turn on/off bluetooth and wifi based upon the time of day. So it turns on wifi at 7 PM M-F and turns it off at 6 AM when I leave for work. I get great battery life, and I think it is due to the radios I turn on and off.

Believe it or not, activating wi-fi when I'm at home has actually increased my battery life substantially. No need to even turn it off; at the end of the day, it takes about 2% of your total battery life.
Care to post the "Power saving" app you are using, TC? The one that can activate 3G after the screen turns off? For so long I've been looking for such a powersaving app.
So i installed Juice Defender and immediately noticed a sizable boost in Battery life... BUT... my Data connection was more flaky then it was at stock
So one day when it is critcal mass I uninstall it real quick so I can have the data connection I needed so badly at that moment. Well... after that the battery performance has been MUCH worse than it ever was before.
Anybody deal with this yet? Anybody know how to set the program not to mess with the data... or how to....????
My rooted GNEX config is in the sig.
I found that is messed up my data connection too but that's the most part if how it works to save your battery by switching to 2g when screen off and 3g while screen on. At least that's how its meant to be. I uninstalled it as 3g would rarely come back on.
Look into other settings to save your battery like screen brightness, auto snyc, GPS, wifi (if your not in a place with it), lock sounds, key press sounds, vibrate on touch, vibrate on key press in keyboard. There's loads of things lime that which really help.
Maybe also look into certain apps being high memory usage in settings menu and look into how many apps you got installed.

This may not be of much help, but I used it for a long time with my tbolt and never had an issue, but no matter what I did with the bionic it would almost never regain data with screen on. So I think it *might* have something to do with the actual hardware. Don't quote me, just my two cents. However, after uninstalling on the bionic I didn't have anymore issues with data than I had before installing.
Oh, and I forgot to mention that juice defender saves battery by killing the data connection. It doesn't save battery any other way.
Same deal here. I just set the app to not mess with Mobile Data by clicking the customize button under profile and going into the new Settings tab that shows up then disabling the Mobile Data option. Still testing...
2x battery
I had trouble with juice defender also so I changed to using 2x battery and I have had much better results.
Toggle the 4G by swiping down and unselecting 4G, wait 10 seconds, then toggle 4G back on. It will come back, everytime for me.
ever since Gingerbread came out, JuiceDefender is not recommended for android OS
Pretty much the only major thing Juice Defender can do to "help" battery drain is turn off your network (or toggle it to 2G only on GSM phones, 3G only on LTE phones) when the screen is off.
It generally wastes more battery frequently toggling it on/off when the screen changes state than it saves by doing so. Not to mention that you can't get background alerts etc. when Juice Defender is toggling your data around.
The only time it ever really saves you anything is if you're not turning your screen on for long periods of time, in that case you could simply manually toggle off your data if you know that will be the case. Juice Defender runs as a process in the bakcground constantly, which effects your battery negatively also.

pretty much what he said. I used JD Ultimate for a month before I gave up on it. I don't notice any decrease in battery life since I did so. Betterbatterystats showed an awfully high number of wakelocks when JD was active. The wifi "Location" feature was nice though.
Like previous posters have said, the problem with JD is that when it toggles you data, it will force your phone into an awake state which drains a bit of battery. I'd like to add that, from personal experience, if you usually have JD toggle your data on more frequently than at 20-30 minute intervals, you might as well turn off JD. The battery saved from turning your data off and the battery wasted putting your phone on an awake state isn't worth it. On the other hand, if you toggle your data less frequently than every 30 minutes, the benefit exceeds the cost and JD actually helps you save battery.
Since I need my data more often than that I have turned off the data connection management. I still leave JD on for the location-based Wi-Fi management though. That's actually useful and saves me having to worry about turning on my Wi-Fi when I get home/to college.

I'm never a fan of any so-called battery saving app.
All they do is turn off your data or turn down the brightness.

I'm a fan of Back button long-press kills app. Then i just check for bg processes of said app and kill them as well.
If i have apps that need background sync, i always make sure either to leave wifi or data on (i know it won't need much, a few KBs maybe) so that apps will have connectivity when they need it, or, if available, sign out of the app (examples: gtalk, latitude). It will cost me more battery if the app keeps trying to find network connectivity and not having it, than the drain of wifi on or data call active.

I disagree. When I used it on my tbolt went from a drain of 40-60 mAh to 20-25 mAh using battery monitor widget polling at 60 sec intervals. And I never missed anything. But I used jd ultimate that allowed data when apps requested it. I also typically got 6 extra hours of use, which meant I could make it though an entire work shift vs. having to recharge after lunch. The only reason I'm not currently using it is because of issue with the bionic data not restarting. That's the reason I think it's an issue with hardware compatibility. Because even if I let the stock Android manage the data connection I still have issues with data restarting on the bionic.
Juice defender did really extend my battery but I found the only part I really used was the WiFi location feature. I started using WiFi unlock at home and got [email protected] to turn off WiFi when I'm away from home then turn it back on when I get home. Yes, I'm that lazy/forgetful.
JuiceDefender was great on Gingerbread and Froyo, but I've noticed that it just seemed to hurt more than help on Honeycomb and ICS. My battery life on my GNex, in my use case, went up when I uninstalled it, as did the data drops I'd been having.
I suspect that as stock power consumption continues to drop with new OSes, JuiceDefender is going to be viewed as a relic of a bygone era.
I will have to say that it has helped my battery but in my work environment I lose signal while my phone is in my pocket plus I can't check my phone for two hrs or more. So I would say in my case it has helped since I would forget to turn data off. I also changed my settings to toggle data every 30 min instead of the default of 15.

I was talking about JD's performance on ICS; on the Galaxy Nexus specifically. JD was great on my old Gingerbread and Froyo phones but with ICS it seems to be obsolete (under the conditions I described in my previous post at least). I don't know if it's just how ICS works or if it's because JD hasn't been optimised properly for ICS but that's how it is right now.

I bought JD Ultimate, and eventually had to uninstall it after I found it was causing too many glitches in ICS. I wasted 4.99, but live and learn I guess.
Tasker
I found this cool app Tasker. It can do functions defined by you on meeting the circumstances you have defined. Like, I have a profile of enabling GPS on openining of maps and disabling afterwards.

This is illegal, if you cant buy an app dont use it.
It's a paid app
WORTH EVERY PENNY
I have automated mine to do the following
As soon as I enter my work car park, it drops the volumes, switches off WIFI
I leave my work car park, volume to max,
I enter home, WIFI on, Volume max
after 11pm - 6.30am everything on silent, wifi & data off
then when i scan my NFC tag in the car, switches on GPS, loads co pilot
re-scan tag, turns off GPS and closes co-pilot

Sounds cool
But mine is too extra complicated to share, I now have over 30
But the most i like is nightmode,
It make brightness 10/255 and opens an app screenfilter
It makes brightness extremely low and this all happens from 12am-3 am
IF YOU LIKE MY WORK, THANK ME BY THE BUTTON BELOW
Anyone knows what effect this has on battery life?
It doesnt waste battery that much, why dont.you try it and see battery stats

Was thinking the same. Any partial/wakelock issues caused by the program constantly assessing the environment. As it happens I am thinking of using the program to reduce battery drain and shutting down WiFi when out of range of home networks but if it's negated by the situation above it seems pointless for my needs.
Any one care to comment?
I've been using Tasker for a couple of years accross 4 different devices now (X10i, DHD, TF101 and GS3). I have a lot of profiles set up to do various different things and I can honestly say I've never seen a noticeable effect on battery life.
That said though I don't use the GPS location state at all. I imagine that particular state would drain battery pretty quickly. I use the WiFi Near state a lot though and, as I've said, never really noticed a detrimental drain on the battery.
I suppose it depends on what you do with it but overall IMO it's a very well written app. Extremely useful too.

Waiting for app sale. The price is slightly higher than what I'm prepared to spend, especially because there is a free alternative from Microsoft called on{X}: http://techcrunch.com/2012/06/05/onx/

Yep! This is what I was hoping to use it for too. My betterbatterystats has identified my Wifi as the one real drain on what is still a very good battery life. So although I could turn it off myself I just know I will forget to turn it back on at home and would like a program to do it for me. BUT if one negates the other it's not worth the effort.

Well your WiFi has to be on to use the WiFi Near state. You could potentially combine it with a Time state too though. Just for example you could have Tasker turn WiFi on for 1 minute once an hour to check for your network(s) then either turn off again if no network detected or connect and remain on if a network is detected... if that makes any sense!
It would save battery compared to leaving WiFi on all the time.

What effect does it have on, I have a task to turn of Wi-Fi during 10am and 1pm; but I try to turn on Wi-Fi during this period. Will it automatically turn it off again, or allow me to continue to use Wi-Fi?

It will allow you to continue to use it. That sort of profile works as a toggle based on the time state so at 10am it will turn it off - but only at 10am. If you were to turn it on again straight away it would stay on until you either turn it off manually or another profile kicks in which is set to turn it off again. The same goes for anything else such as ringer/silent/vibrate, mobile data, GPS etc.
@Greedyfly: you're welcome

Tasker can do wonders...but it requires you to be some kind of Tasker-scientist to get things done. I recently discovered Llama as well. It's free and simple but capable.
Yeah Tasker does have a reasonably steep learning curve admittedly. By no means insurmountable to most though.
I suppose it depends on what/how you want to automate. Tasker is very powerful but not so simple. Llama is free and easier to use but no so powerful.
Both are good automation solutions. Locale is another one to check out.

I've been using Tasker for the best part of a year now, awesome piece of software. Negligible impact on battery life and it's astoundingly powerful. A few examples of profiles I currently use - detects headphones/bluetooth headset and reads any text and who sent it, useful when cycling or out on the bike. Disables screen lock when at home, I use the phone as a control for my media centre so it remains unlocked at home and turns the screen on as soon as the handset is picked up, controls a variety of connection states according to location and time.
These are just scratching the surface. On top of this I've had direct dealings with the dev on a couple of occasions, genuinely nice bloke who does his damndest to solve problems as quickly as possible. All in all, this and Titanium backup are by far the two most useful pieces of software I've bought:good:

I love tasker even if it drains my battery(but it doesn't)
Press the "Thanks" button below if I've helped.
I have had the Captivate Glide for little over a month now. It was the rooted rogers version but I flashed AT&t's rooted ICS on to it.
Major issues were battery life and GPS.
Without changing any software I wanted to solve the issues or make them tolerable at the least. Probably better ways of doing this, but this is what works for me.
I assume everyone else is like me and downloaded tons of apps that we like. I personally have 30 downloaded with some form of Google being responsible for at least five of them. I also synced my google account, as well as my outlook account and skype account.
I do not game on my phone I prefer the console style of gaming but I digress.
Simple battery life can be saved obviously by closing or backing out of applications when not in use. You must be avid about this in order to preserve battery life. If you have not altered your ICS it comes with an "Active Applications" widget that makes this simple and easy. Within that widget is an even better function that allows you to clear memory on your ram. Do that for superior battery life as it will close down any program running including back ground processes.
You should also have widgets that allow you to toggle WIfi, and GPS, Bluetooth, brightness, screen time out, sync, and settings. <Extremely helpful in saving battery life. Wifi should be used whenever possible. If your phone is running processes that use data and it probably is, its better to use Wifi for your battery. Turn Wifi off when you can not secure a connection because the phone searching for wifi to connect will eat your battery.
Turn off GPS when not in use. If using an app that likes to have your location you can keep GPS on but turn it off when not directly in use it saves battery like no tomorrow.
Screen brightness is also a huge factor in battery Life. If you Go bright you die, simple as that. Make your screen as dim as you can but still comfortable to see depending on what you are doing. Again the widget makes this super fast and easy but you can go into the settings and adjust this by percentage if you are particular. Other wise the widget allows Bright, half bright, auto bright, and no bright. No bright will save tons of life so learn to see in the dark haha.
Screen timeout at 15s will save tons but can be annoying if your in the process of using your phone. I uses it and just tap my screen if I need it to stay light but trust me it gets old fast but so does a dead battery.
Go to your individual synced accounts and adjust the sync intervals to specified times if possible. Usually find it once you open whatever account and go to its settings. That gives the battery some life in between syncing which uses data and eats battery.
Go to settings and toggle system power settings. This Saves a huge amount of battery life and I have no idea why. You may be tempted to customize but don't. The system power saving is far superior from my experience so far.
One last and final thing to save battery life. The Google Play Store. It runs a ridiculous amount of Background processes. Go to settings, then, data, find the play store and click it, scroll to the bottom and restrict the background data. You will have to turn it back on in order to use the play store and some other apps which leads to my next topic...
GPS
This captivate glide has a notorious rep for being ****ty in these here forums. I am here to tell you its not all true. I am not a software guy as you can see all of my advice is simple common application usage advice. I previously had the SGH-I827 and its GPS was spectacular so I found it hard to believe the captivate glide GPS would not perform well. In fact when I began to use it, it did not. It was glitchy and unreliable. Terrible at best. I thought I was going to have to buy another phone or do some software stuff I had no clue of. I was patient.
And for myself I figured it out.
Everything you do to this phone is reflected in its functions.
All the things I suggested to save Battery Life impede the GPS of this phone. Take that in...
I started over from scratch resetting back to factory settings. (leaving the Stock rooted ics). If your google account backs up all your apps they will begin to re download immediately once you sync your account again, BUT STOP IT!
Don't let anything Upgrade or Download to your phone automatically. This is crucial.
Google maps upgrade must not be allowed. Instead use the current version that comes with the ice cream sandwich OS. (includes the navigate button we all like as well as the places icon) Everything else can then be downloaded or upgraded in the play store manually.
Now, for the tricky part. you have been saving battery life using all the propper previously mentioned techniques but now you want to use GPS. First thing you need to do is uncheck system power settings.. Then allow google play services to have its background data back. Settings, data, google play scroll bottom yea uncheck it. Turn your screen timeout to 10min. Now toggle GPS back on. But wait one more thing, Clear the ram. All done in that order Now when you go to maps you should get a lock in under a minute and it will be reliable. No way of stopping GPS from consuming a ton of battery but if you dim the screen and charge it while in use you will see battery life gains instead of losses.
Thanks for reading my personal usage experience so far. I have yet to take the update to GPS to see if it still works in the same fashion because I am a coward and I like my GPS right now. Let me know if anyone experiments further. With the rooted ICS OS.
