Battery Life Claims vs. Reality

I stopped by an AT&T corporate store to get a hands on with the Captivate. The salesperson there tried to tell me that the standby time on the device was 15 days if you kept apps from running by downloading an app killer. I asked if he really meant 15 days if no radios were running. He said "nope, 15 days is pretty easy".
Really, folks... what is reality here? Is it similar to other smartphones, where a day with moderate use is reasonable?

There is no way the phone will last 15 days in standby even with a good task killer. How can the sales rep tell you this if he only had the phone in store for 2 days?

That's a very good point... but he was very sure of his claim. I pulled out the "I'm very skeptical" response and walked away. Oh well, looks like once again, truth is in the internets somewhere, not in someone who should know such things.
Another element to this is whether an upgrade to 2.2 will increase battery life. I work away from any ability to charge and really need a phone to hold up all day.

Well, my N1 holds charge for about 1 day with moderate use. As soon as I play with the GPS and google's built in nav system I get maybe 4 hours worth of usage. Another issue I have with my N1 is that my car charger cannot keep up with the drain, so even plugged into the charger the battery percentage is decreasing. Sure hope the Captivate is better in that respect.
Froyo did increase battery life a bit but it is not earth shattering. The advantage of this phone is the larger capacity battery and hopefully a less power hungry samsung processor than the qualcom snapdragon.
I am sure within the next few days we will have some folks with more concrete consumption estimates.

i don't know... while the 15 day claim is a bit much, mine was fine with heavy usage all day yesterday on the half charge that it came with from AT&T... given that, i think that it should last 2-4 days easily with only light-moderate usage.

My battery lasts me all day. It's just marginally worse than my 3GS I think... My 3GS always had extra at the end whereas my Captivate seems to run out when I'm going to bed.
So... It lasts all day. That's really all that matters to me.

My battery has not been able to make it through the day. Don't know why yet. I have my email accounts set to 30 minute sync schedule, have Wi-Fi and bluetooth off. Don't know what is going on. Still researching. Will see how it goes for a week. Might be a bad battery.

i find that dark backgrounds help. Also keep unecessary things off and dl an app killa. I had a new captivate today at 10am and with its half charge and heavy usage it lasted me till 6

by heavy usage i mean constant surfing and dling shiz. I didnt use gps wifi or play a movie. also played that free mario game for bout an hour.

After about 11.5 - 12 hours of very light browsing (maybe like 1/2 hour 3g surfing, no calls, all apps killed with task killer every once in awhile) with Bluetooth and Wifi off I am at 68% left. This is with auto brightness.
I'd say if you don't do anything you might be able to get 3-4 days out of it. According to my battery stats 78% of all my battery usage has been the screen. Keep that thing off / or low brightness and you are going in the right direction.

i bet by standby att means the phone being not used and turned off for like 4 days lol

By dark, he means a background that has a lot of black in it. This is really helpful because the Super AMOLED screen on this phone turns off power to pixels that are black, so basically that part of the screen isn't using any power. A black background is almost like turning the screen off.

this, thanks for clarifying.
note: it further helps if you apply a static one.

I was able to listen to music for 6 hours at work, show off my phone (I only showed it directly to one co-worker - I had 5 other guys come to check it out after he told them about it lol!), did some light surfing, downloaded a few apps and generally fiddled around with the phone and ended up at 43% battery. Not great, but not terrible either. Screen was the big killer here. GPS and WiFi off except to test Layar.
We'll see if battery life improves, but it enough to make it through one day easily for me. Forget to charge it and it'll be flat early into the next day though. I'm a bit disappointed, considering benchmarks on the Galaxy S came up with nearly 8 hours of constant video playback. I think they had brightness at 50% and I kept setting mine to max to show off the screen and then forgetting to set it back, so that could be part of it. I was definitely expecting more though. I'm clearly not the most demanding user here, so I was hoping to potentially eek out two days of usage (just in case I forget to charge it).
One of the reasons I went with the Captivate instead of waiting for the Epic is that the form factor seems to be a bit more amenable to adding an extended battery. Hopefully we'll start to see some 2500mAh or even 3Ah batteries show up - even if it means getting a new backcover. THAT should just about do it

Also the Super AMOLED Screen sucks alot less Juice as well...
My friend has the Vibrant and has had it for about 4 days. He is a power-user like me, and he said with his task killer, he can run the phone for 2 days on a full charge. This is outstanding for a smart phone... I ordered my Captivate today, should be here on Wednesday so I'll also put this to the test!

better battery life is coming once devs hop aboard. Also, your phone will need training over the next few days so it can only get better from here for you. I also recommend just leaving brightness on auto detect. You wont have to play with it as much and forget it on super bright.
Some more tips:
idk if you guys like haptic feedback but i think its annoying as all hell. Turn it off to save an iota of battery.
Also tone responses for menu clicks? ANNOYINNGG turn that shiz off for a squirt of juice.
Lastly, unless you live by your email, turn sync off and only sync manually when ur curious about it.

I wonder about some of the widgets. I have Weather And Toggle Widget (which I prefer over Beautiful Widget), and have it set to update the weather every 30 minutes. Wonder if that's too often. The weather in Iowa can be very unpredictable and change quickly, but I'm inside all day so it doesn't really matter. I guess it's just eye-candy mostly.
I also wonder how WATW compares to BW in terms of battery consumption.
I turned haptic off (I agree, it was annoying). I turned the tones off, though I doubt that will affect battery life. I wish I could keep the tones for dialer and kill it for the keyboard.
EDIT: I keep reading about this idea that you train your battery (or device) to your usage, but I'm not sure that I understand/buy it. I could see perhaps something to do with the memory effect if these batteries are susceptible to it, but this idea of "training" it strikes me as very odd. Does Android have some kind of battery optimization algorithm that adjusts services based on your usage or something?

from what i understand, calculating battery life is like a guessing game. calibrating your device by letting it drain out and then fully charging it and draining it out again completely gives your phone an idea of just how long it can last on a single charge. Until you do a few cycles like this it will incorrectly display batter life percentage giving the user a false sense of security or panic. There may be more to it that has to do with the actual battery itself but idk the rest of the details.
and 30 min updates is a bit much lol. u should update like once a day and manually refresh if you need to know b4 u go out.

I'm getting very good battery life on my phone. As good as any iphone I've had and better than any of my windows mobile phones before that. I don't have any widgets constantly pulling down data though and only have my google account syncing contacts and calendars and an exchange account running.

Battery is absolutely garbage

Am I the only one?
I upgraded to a native android device from a modded HTC HD2 to hopefully have a longer battery experience.
This battery is absolutely trash. My 2 year old HTC HD2 running Sense Android Non-Native ran at almost exactly the same.
I tested my HTC HD2 side by side with a close friend who has an Evo 4g.. Both Devices still being HORRIBLE in battery life performed almost IDENTICAL.
HTC HD2 is TWO YEARS old, why is it so close in performance to our device..
I love the phone in general, it's snappy (once i removed all bloatware).. Boots fast, runs nice.. i have very few complaints about it.
But how does an 1100 MaH battery run the SAME as an 1600 MaH battery?
I thought technology is supposed to improve, but my non native android phone ran almost the same as this one. Took longer to restart/boot up, but general speed is the same, larger screen size.. similar settings, and same battery life. Pisses me off frankly.

That's how I felt. hopefully we will get rom's or gingerbread on this phone soon that will improve battery life. And by gingerbread I mean the leak from Samsung for the i9000. I've been reading reviews and it seems like it Greatly improved battery while speeding up the phone a lot.

I have to disagree. I've owned may android phones including the evo. This phone has the best battery life in my opinion. I can easily make it almost all day with use without charging
Sent from my DAMN Galaxy 4G¡!

Well like I said, i admittedly abuse the phone.. but I'm comparing to other phones getting equal abuse. It stands up about the same, better yes, but not by much.
If I'm barely using it however.. let's say, mainly just texting, yes it will last all day. But that never really happens.

I love how people admit that they "abuse" the phone all day and then complain that the battery life sucks. If you're going to use your phone that much, bring your usb cord. Or strap a battery pack to yourself and plug it in for "all day" use and abuse.

It's the screen. If you want the super amoled you have to put up with the battery.

What i don't understand is that why the Droid x which has similar specs to our phone can go up to 10 hours of continuous web browsing when our phone/vibrant can only go up to 4 according to tests. Is it because of the screen? If it is then that's just stupid.
Sent from my SGH-T959V using XDA App

It was horrible for me at first, but I then realized the system has to calibrate the battery first. I am getting about 16-20 hours with moderate usage now, which is better than the G2 I had before.

My g2 can go up to 28 hours with light texting and 2 hours of web browsing through wifi and 10 minutes of calls (manual syncs and low brightness also). Once I use the gps and browse through hspa, it's a different story. My sister has a SGS4G and her battery seems to drain faster than mine.
Oh, and if I keep my phone charged for a while after reaching the 100% mark, it stays at 100% even after 1 hour of heavy browsing and watching videos. I think we should all just assume that the battery meters are inaccurate.

I use juice defender and put my brightness setting on auto and I can literally go all day with "abusing" my phone.

Sent from my Galaxy 4g using XDA Premium App

let the phone die, to the maximus. meaning once it turns off, turn on again until it doesnt turn on anymore. Now fully charge it, once again when fully charged restart the phone and charge it to 100 again. then let it die again, and full charge. should be fine then

i bought a 3500mah extended battery for my phone. the battery is designed to work with vibrant. it really made my life a lot easier.

I noticed if I set the phone to GSM only, battery lasts almost twice as long. If I'm on auto select (WCDMA/GSM), it lasts from 7AM till about 4PM.
But then again, I don't have a very good 3G/4G reception (or 2G connection for that matter), so my phone is probably working extra hard to find signal all day long.

The new Bali Kernel has shown tremendous battery improvement on my phone. I'm really impressed.

Same here.
I used to only have dark wallpapers and take all the other extra steps for my battery to make it through the work day, and as soon as i got home i had to charge it.
I'm now running fireflies live wallpaper, abusing the phone a little more then what i used to, and i still have battery to spare, not by the time i get home, but by the time i go to bed!!

i also have installed bali. seems to do well, as said its all about the brightness.

My problem with this phone is that wifi uses way too much battery. I have it to turn off when phone is asleep but i'll have the phone at 100% with wifi on. Put it on sleep. 4 hours later. battery is at 65%.
If i have wifi turned off. Battery will be at 98%.

G2x battery life

Just wondering how is the battery life on this phone, had the chance to play with it @ a tmo store for a good 1 hour and its an awesome device ran benchmark on it and it scored really good, I was suprise it beat the G2 even when I overclock it to 1.42 ghz lol. I really want to know about the Battery life in these dual core smartphones, as I'm tempted to get me a G2x.
T-Mobile G2 1.42 GHZ

It really depends who you ask about it. There are a ton of battery complaints whereas I and many others find the battery life to be exceptional.

I think most of the people complaining about battery life either
A) Haven't performed a factory reset which fixes the phones constant power usage even when idle. OR went into the hidden menu and changed the radio to GSM and WCDMA Auto.
B) Have a defective battery (ie those who say their battery drains even when the phone is powered down)
C) Have unrealistic expectations for battery life all together.

Well on point C, I can say with absolute confidence that this battery is the best I've ever had out of all my smartphones (PPC-6700, Mogul, Touch, Touch Pro, Touch Pro 2, Curve 8330, Bold 9700, Palm Pre CDMA, HTC Hero, Evo, Inspire, and the Samsung Captivate) with me being able to talk for four hours and still have 30% of the battery left and then I can game for another 2 or 3 hours. Most of those phones would have been dead after the phone calls (the Captivate would be close to death, the Curve would be about an hour behind it) let alone having to power such a nice display and high-powered graphics chip.

I tend to think the actual answer is (d) the battery driver is so vastly broken that any reading it gives is essentially fictional. In this case, some people will be happy with their battery life (because their readings are fictionally high) and others will be freaked out (because theirs are fictionally low) but the actual answer is "nobody knows".

This battery outlasting my Vibrant by hours with the same usage pattern isn't at all fictional. Not saying the drivers arent messed up.. But if battery life is as good as it has been for many users already it can only get better. Either way in its existing state its still better than many android phones.

Not at all convinced that it's accurate - still saw something like a 60% drop in a few minutes, on a brand new battery.

Exactly. If the battery driver reads "0" then it will shut off. That doesn't mean the battery is depleted. This explains why you'll get awesome battery if you clear battery stats on a full charge initially. It aligns the counter with the actual battery.
Mine runs from 8-midnight with some to spare with heavier then normal (thanks xda!) usage.
LG G2x - CM7 2.3.4

The G2X has with out a doubt the best battery I have ever had on a smart phone and has been since day one. I never had any battery problems but that might be because since day one I have used SetCPU, rooted my device and froze all of the bloatware including WiFi calling. I constantly get about 15 hours with moderate use and 8 hours with heavy use which includes 1 hour worth of playing games, 1 hour browsing the internet, 1 hour reading all of my RSS, 30 minutes reading Fox news and CNN, 50 text messages, 1 hour of phone calls, 2 hours streaming music or playing my MP3's and about 30 minutes browsing facebook and twitter.

Only thing I don't like about the phone is the lack of hardware keyboard especially because tmo considers it part of the G series which it doesn't fit in, and only god knows I what I would do if this phone had a keyboard to get it LOL I would rob a bank.

Unless suffering from some issue idle drain is awesome. Afraid not much can be done about the drain during use though besides turning screen brightness down and using wifi instead of 4g.
I pretty much never use wifi anymore because its so damn slow.. but hopefully that will get fixed because with wifi on battery life is just unreal even when in use.

Guess, I get to ask for help. [Ticket Closed for Now]

Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.

on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?
http://forum.xda-developers.com/showthread.php?t=1450962
kernel: http://goo.gl/ZqBZl
btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha

Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search

Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues

fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms

I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.

Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

Thanks again. I'll definitely try the wifix along with the rest of your suggestions that apply

I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.

I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.

I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(

Horrible battery life. Typical or bad phone?

First off, yes I realize that complaints about the Skyrocket battery are very common, and coming from a Nexus One I'm no stranger to the nightly charging, but I feel like my phone may have a real issue with proper battery management. For example, I'm looking at my phone now. It's been on for 4hrs 43 mins and is down to 73%. Screen is 61% usage and then the typical other stuff below it. For the record the screen has been on for MAYBE 20 minutes total for answering texts and checking Facebook/twitter updates. I should also note that I am using the Galaxy Nexus extended battery. I feel like every time I turn on the screen I lose 1-3% of battery. For the record, I've tried multiple Roms (Stock, SuperStock, NexusMod, Sky ICS, and running CM9 RC2 currently) and multiple radios (running RUXLF3 currently). I've tried underclocking my CPU with SetCPU and that doesn't seem to help. I just installed JuiceDefender but I don't see that doing much as I can't really turn off data with the screen off because I'm connected to my company's email (refreshes automatically every hour.) The only stuff I get pushed to me is Gmail (and I consider a very busy email day to be 5 emails in a given day). I don't get Twitter or Facebook updates sent to my phone. And yes I have Wifi/BT/GPS off as I don't need them. I'm not in an LTE market and thus am using HSPA+. However, when I WAS in an LTE area (NYC and Atlanta) the battery drain was almost to the point where I almost hoped I DIDN'T get LTE in my market if it meant my battery life would be as atrocious as it was.
Within about a 8 hour period it is not uncommon at all to be around 50%, sometimes dipping as low as 30% depending on how boring my day is thus resulting in more FB/Twitter checks than normal. I know that the Galaxy Extended battery isn't going to give me life on par with a Razr MAXX, but the difference I've noticed between the OEM and Extended seem almost negligible. Is this considered "Typical" performance or am I doing something wrong either software/hardware wise? Could I just have a bad phone and try and get it replaced since it's still under 1 year warranty? I'd prefer to not have to do that unless necessary as it means I need to back everything up and then wipe out my data and go back to Stock and reset the flash counter and then do the ICS update via Kies (because I know AT&T will fire back and say "Try out ICS first and then return if that doesn't work!") and all that fun junk.
Thanks

Sounds about right to me. Just turn off data when you aren't using it is all I can say.

My thoughts:
1. 50% in 8 hours of moderate use is, imo, not terribly unusual for a Skyrocket without a ton of fine-tuning done to it. The Skyrocket, in general, is not a marathon-runner of a phone. It's better for short sprints, although you can (as I have) make it a marathon runner with extensive tweaking.
2. I haven't tried all the ROMs you've listed, but I can tell you that CM9 on my Captivate and my Skyrocket had severe wakelock issues. My Skyrocket's battery would drain off at twice my usual rate when I tried it, and the ROM prevented my Captivate from sleeping at all (I was lucky to get six hours out of a charge--at best). It's not my favorite ROM for battery life. SkyICS, in my experience, is the absolute best battery life of any ROM.
3. Get rid of JuiceDefender and SetCPU. JuiceDefender works primarily by preventing applications from doing what they want to do. Common sense dictates that when a computer program is unable to do an assigned task because its primary method of doing so is blocked, it will try something else. That "something else" may or may not result in a series of wakelocks. SetCPU is designed for single-core processors. The changes it makes will usually affect only one of the two cores in a Skyrocket's CPU, causing the second core to do weird things. I do, however, recommend using System Tuner. All you need is the free version, because all you need to do is lower your min to 192 and change your governor to ondemand or conservative (I use conservative). You're not forcing new profiles onto the phone's CPU, just giving it a little "attitude adjustment".
4. Get rid of the Facebook app and replace it with Friendcaster. Like, now. The Facebook app uses battery and data even if you tell it not to.
5. Have you downloaded BBS? If so, are you using it to track down your wakelocks? I've got a post inside of the above thread that explains how to do so and, well, explains just about everything else I've already said here or would say if I continued. So, yeah, just read that thread. It's not terribly long, and there's a ton of great info in the OP and throughout.
For reference, I'm a light-to-moderate user of my phone, not as heavy as you by any means. I'm not in an LTE area, which helps. That being said, with the Nexus extended battery, I'm now at 2 days, 5 hours and still at 23% charge. I used the phone very heavily while traveling a couple of days ago, starting at 7:00 AM Eastern at 100% and ending at 11:45 PM Mountain with 11% left, 4h45m of screen-on time.

I just find that odd since I find people giving great stories with the SKY ICS and others in terms of battery life. Ironically, I've found that SKY gave me some of the WORST battery life which really made me feel like a dolt. Here's the latest battery stats attached. Perhaps my view of things is skewed though because my day starts at 6am and I'm at work by 7 (with my phone typically turned on at 6:30) so I still have a good portion of my day left by the time I get home and my phone is typically less than 50% by that time. It's weird to know you have about 7 hours left in your day and your phone is saying like 40% power left.

What's your screen-on time in those screenshots? The frequent wake-ups make me think that you've got some rogue apps syncing when they shouldn't be.

Hello OP, I have exactly the same problems as you except i'm still running stock (rooted with frozen bloat). I tried the Galaxy Nexus Extended Battery and from stock it was more horrible. appox 1 hour less than the stock battery. I did try not using my phone like normal (about 25 mins of screen on time) which was a PITA because mobile internet is my only way to sneak down time while watching my toddler son. The battery lasted 11 hours. With stock battery, I would've lasted around 10 hours. A lot of people say it might be bad battery BUT how can I have such terrible luck to get a bad stock and a bad GNEX ext batt??? lol. So I ordered the qcell 3800mah extended battery and boy I won't be looking back!!!! I am currently still at 25% battery, 17 hours 20 mins with 3 hour 38 mins screen on!! I watched two Naruto episode last night and didn't have to worry about my phone dying while I'm sleeping and end up not getting important calls from husband early in the morning. The hump doesn't look great but it does not bother me when I'm holding the phone and I have small hands. The weight is a little bit on the heavy side but for so much more battery hours, I don't think you'd mind. Now, if you are the type who is always out and can't find sockets all the time, I suggest you try this qcell ext batt. for $20 you can't go wrong. I know you'd hate spending another $20 but trust me the battery works wonders.
On a side note, i also ordered a charger for my standard and GNEX battery from ebay so I can charge them independently if i ever have to go on long long trips and need super juice. That's another $4, takes two weeks to get here from China. There's a hack here in XDA somewhere to make it a really fast charger because it is really a SLOW charger despite what their ad claims.
Good luck!!
PS: I also bought the SetCPU since everybody swears by it. I never saw any difference.

I just checked and it says 1 hour 4 minutes. There's NO way it's been on that long, or at least not with me looking at it, and I usually turn off my screen when I'm done as opposed to letting it go to time out, which is 60 seconds anyways. I'd say 30 minutes would be it AT MOST.

My goal is to avoid the super extended battery because then it means I need to buy a whole new case as well. I'm one of those people that "needs" a protective case because the only reason I have the Skyrocket is because last December my 1 year old took my beloved Nexus One and threw it down 16 flights of stairs. The phone then entered a vegetative coma state and never recovered. I can't have that happen again. So basically I'd have to buy the new phone then buy the new case. I'm trying to spend as little extra money as possible.

well, there are hacks floating around with otter box to fit the hump back. I'm sure you will find other cases from ebay that can be hacked this way too. I don't have this problem since Ii use my phone naked because i only got it for $10.00 and my other line is due for upgrade soon. anyhow, it really depends mostly on what you would rather have, battery life or case. It could be the phone but most likely AT&T will tell you that smartphones consume a lot of energy and if you are not within that 30 day period anymore they'll probably give you a refurbished one and you might end up with a more dud one than the one you already have.

I try to keep my phone out of my pocket because I don't think cell waves near my "area" is a good combination. When I am at work it's on my desk for about 7 hours, and then at home I usually leave it out (at a high elevation away from my daughter of course.)

That's still a little high. I was going to ask if your volume rocker wakes your phone, as that can be a big phantom screen-on culprit, but if your phone's on you desk most of the time...
Download BBS and pin down your wakelocks and alarms (which cause wakelocks) from there. If your phone's not suffering any extreme drain from a rogue app or process, then you might just be at the best you're going to get for your usage.
Have you tried different radios at all? I've heard those can have a minor effect on battery life, depending upon your area.

No but the 4 buttons do as it is a CM9 feature. Honestly though they aren't on for very long as I usually am near my phone and notice such things rather quickly.

I don't use the volume rocker for waking just FYI.
I got BBS. It looks informative but I'm not really sure what I should be focusing in terms of statistics and what, if anything should jump out as problematic. Any tips?
I have tried at least 4 different radios but I haven't noticed any major difference between them.
I just saw that CM9 has now been officially released in stable form. Maybe that will help. I'll try that ROM now. I hope CM9 is not the issue, as I've always been a "Vanilla Android" kind of guy and I really like how ICS is designed. I never liked how the other ROMS still had touches of Touchwiz in them. I especially don't like how it mimics iOS styles so much. I mean, I'm definitely pro-Samsung in the major lawsuit, but Apple has more than a few valid points in their argument. Having similar icons and a SMS theme that basically mimics iOS isn't going to help Sammy in the big lawsuit.

True, it's a well-known problem. You may find some rom with better battery life (here is the rom I'm using: http://forum.xda-developers.com/showthread.php?t=1436854). You can also download some apps that save your battery. Try to turn off GPS, Wi-fi and data when you're not using, and also do not keep the brightness of your screen too high. I hope these would be helpful to you.

Check the link in my sig for details on how to really use BBS to improve your battery life. You're not that far off of a normal battery life for moderate to heavy usage, so just tweak it and go from there.

The thing is though is that I don't consider myself to be a moderate to heavy user, but more of a light to moderate. As I said, on a typical day I answer maybe 5-15 text messages, check Facebook/Twitter a handful of times, almost never get emails sent as I have no life, do almost no web browsing, and maybe take a phone call or 2. I very rarely play games and even less often stream media. My gmail is push but that's about it. I also use Touchdown for Exchange but that queries only once an hour. Am I still being unrealistic with my expectations on my battery?

Something definitely seems off, and you may well have a bad battery or even a bad phone. Try to go through and clean everything up in terms of wakelocks and any possible rogue apps. If you're still in bad shape after cleaning up your phone, something seems off. Mobile data does chew up more battery than Wifi, but not THAT much, and especially not in an HSPA area.

I don't think it's a battery issue. I've used the OEM and the Galaxy Nexus extended battery and both are delivering similar performance (although GN is slightly better obviously.) And as I mentioned, when I was in an LTE area my battery was getting beat down like Homer Simpson in a fight with Drederick Tatum.
Would it be advisable to try a FULL wipe of my phone? When I was installing CM9 today I saw the option to format EMMC. Should I try doing that or wiping other stuff or would that just do more bad than good? Should I try wiping that and/or the SD card?
