Battery stats for those on custom ROMs

Im trying to convince myself to get the Inspire and sell my atrix.
The last thing that is making me reluctant is the battery. I consitantly get between 30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time. I know i wont get that with an Inspire, but im wondering what kind of stats people are seeing who are running custom ROMs. With my capitvate i saw a nearly DOUBLE battery life effect between stock and a custom rom. im hoping there are similar results on the inspire.
for those on custom roms, im looking to see how many hours you get between charges. ideally, how many hours between charges, with how many hours of screen time, wifi, blue tooth, etc. and im also interested in seeing the battery life of those who are OC/UV.

Someones gotta have info for me!

Inspire battery usage....sucks!
If your main concern is BATTERY USAGE, then DO NOT get an Inspire.
No matter what ROM or other MODS made to an Ispire, it is accepted by all that have one, that the Inspire has very low battery uptime, especially when compared to other platforms.
Stay with your ATRIX for long battery usage and uptime. - Glenn

I just swapped my Atrix for the Inspire this past Sunday, and i can tell you first hand you're not gonna get the same battery results you did with the Atrix. Personally, I don't need to get 20-40 hours of battery life from a phone. Don't get me wrong, it is nice, but I don't need it. I just want to get at least 8 hours (while I'm at work) from a battery and I'm fine. However, I do have my charger with me just in case and i also have a car charger.
I rooted my Inspire Sunday night and flashed the stock rooted rom and couldn't be happier. I got about 13 hours out of the battery yesterday while I was at work and I used it under normal circumstances..calling, texts and lots of fb checking etc. Oh, and I didn't have any overclocking, underclocking, themes or nothing...just the rooted the stock rom.
The inspire is a lot more smooth also when compared to the Atrix. I was all for the Atrix last week. But after actually having the Inspire....its the Inspire FTW!

Its not my main concern. Just the Las thing I'm considering. A lot if other things about the inspire are appealing. Just looking for round about numbers.
Can I get 12 hours out of itwith 2 to 3 hours of screen time? That might be enough for me........If can get more than that, then I would def be sold.
Of course all this would be expected only when all aetttings on phone for Max bat life applied

Speak for yourself. My Inspire lasts me the day with a ton of juice left over. I'm not a super heavy user, but I will have sometimes 60-70% battery life when I go to bed on light use days. On heavier use days I'm still at 30-40% when I go to bed. Unless you are watching youtube videos or something for hours on end, battery life is fine I think.

To extend battery life I adjusted my screen brightness back to 30% with no auto adjust, seemed to help battery life quite a bit and did not make much difference in how the screen looked. Today I am trying auto brightness, but using power saver to switch to lower screen brightness when the battery hits 40%--I'm at 7 hours and the battery is still at 70%. Honestly, I don't think a person could even watch a movie on a flight, for example, the screen draw on the battery is that bad. If I keep the phone, I will have to get another battery.

I get 22-24 hours with light average use, about 14 hours of moderate use. CM7, nothing special done or flashed.

I was replying to the OP's original statment regarding his Atrix battery time in reference to the Insire's battery time:
OP said......The last thing that is making me reluctant is the battery. I consitantly get between 30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time.
Even with your light usage, I am doubtful that you get anywhere close to the OP's "30 and 40 hours between charges on my atrix with 3 to 4 hours of screen time". - Glenn

well i guess i will just find out.
impulse buyer here. immediatly ran out and purchased an inspire after making this thread.

You're going to LOVE the inspire (even with the lower battery time). I have no doubt you will be throwing rocks at ATRIX users in no time!! - Glenn

Lol ur right so far. Smooth, fast, solid. Just the smoothness and screen size is enough to win me over

Stock rom rooted and bloat removed, HSPDA enabled:
only have one data point and it looks good so far. I had 75% left with the same average use as the other roms above. Why this one is so much better I don't know.
Also the stock rom came with the stock Radio 06.04.06_M but with the root downgrade and then custom rom to Rev HD4 B2 I had to upgrade the Radio to one that was suggested, which is 06.03.24_M2.
Also, one thing that I noted which was also seen on my Nexus One is that when I use the GPS my car charger is not able to keep up and I will loose battery % as I drive.
All in all I am very happy with this move from the Captivate. Many see it as a lateral move, but if you ever where in the need for the GPS this is definatey an upgrade since the GPS on the Inspire is spot on.

^^^^^^
thats the kind of info i was looking for. appreciate it.
my first run with the inspire resulted in 14 hours since last charge (down to 15%) with nearly 3 hours of screen on time.
granted i adjusted every possible thing to be less battery consuming, and one hour of that screen time was laying in bed in the dark with the screen on the lowest brightness setting.
i think i may be able to work with this.

yeah i am close to an impulse buy on the inspire too, just because its such a great price. even full price at 399 is insanely cheap when most phones are 550 full price.

the battery does suck. but everything else on the phone is so great, that i still am happy i got it

I am a pretty hardcore user and I never have any issues with battery at all. I believe a lot of these battery issues that people have are due to flashing with a low battery, which causes the battery's "memory" to get messed up. If people flashed with a full battery, or did the battery reset procedure after flashing and charging, we would stop hearing about all the horrible battery issues. User error, not an issue with the phone. If it was a phone issue, I would absolutely be experiencing the problem as well.
There are also bigger, better, higher capacity batteries up to 3500 ma/h if you REALLY need more battery time.

alright so i had a lot of issues with getting great battery life out of the phone. i'm only writing this to help people that are having similar issues. obvious, relative to teh atrix (with a ridiculously larger battery), the life is NOT that great. BUT i've gotten 24+ hours on teh phone with certain tweaks.
first off, rooting is a pain in the ass, but a necessity for any power user. My HSUPA speeds are often higher then the HSDPA speeds...and I can tether too! Anyways most important part of tihs is underclocking. I have my screen set to underclock to 3xx Mhz with screen off. I can't even tell the difference between when it is underclocked or not. I don't OC since for whatever reason I don't see the option to and don't care to force it.
I also set my brightness to 20% or less when i'm indoors, which is usually where i am. I also turn off the radios when i'm not using them, or wifi when i'm in range (i think its better than hspa), and sometimes autosync too (there are widgets for this). i also disabled facebook live feed syncing and set it to update when i open the app, and to sync contacts and htc sync and other useless stuff to once a day.
if you want something to turn off your radios when your screen is off, check otu juice defender. if you want to track your battery over time, try juice plotter. with the way i ahve it setup now, if i leave the screen off for 10 minutes. the battery drops 1% or less PER HOUR. One night, it finished charging at midnight so i took it off, and didn't put it back on a charger 1 am the next night with 10-15% left.
anyways, i hope this helps at least some new inspire owners. good luck with rooting if you haven't yet, it took me 4 hours, but itw as COMPLETELY worth it

Got another data point for the stock rom.
This time after the 8h my battery was at 55%, however I spend considerable time in a clean room were I have no signal at all. My other phones would usually drain much quicker in there and I believe it's because it's seeking a cell signal all the time.
So far I am very happy with the rooted stock rom, only wished it had some of the Gingerbread features.

I have consistently gotten about 9 hours usage, with 1.5 - 2 hours screen time, and left work with 40 - 60% battery. I make no effort to reduce usage, as nothing even comes close to the screens usage, except I do leave off gps when not in use. This is a general average, and I have noticed little difference between stock and 2 different versions of Android revolution, with different flashed radios. (roms always flashed at full battery) and overclocked to 1.2 with ondemand set. Overall I can say this battery is not great, but the rest of the phone is well worth it. I had the atrix for 2 weeks, and although the atrix got better benchmark scores, it was way less smooth, and a lot of market apps don't work on it, like flashlights, live wallpapers that don't support the screen, etc.
I am very glad my atrix's touchscreen failed, because if it didn't, I probably would have never tried the inspire, and I am much happier with the inspire.

[Q] Warranty replacement captivate has better battery life?

Hi all -
AT&T just replaced my captivate, under warranty. (Yay - it was bricked, so wasn't expecting much.) All they sent was the phone body - no back cover, no battery, no SIM. So I've still got my original battery.
Interesting thing is that the battery life seems significantly better on the new one. I had 2.1, and at one point, a version of Phoenix ROM on the old one, and made it about 36 hrs max on a charge. This one seems on track to go 3 days, with Wifi and GPS turned on.
So, is Samsung's version of 2.2 that much more efficient, or did I end up with some upgraded chips inside? Any thoughts?
Original was REV0.4. New one says 10.12 in same location on sticker under battery (I assume 10.12 = manufactured in Dec 2010).

I dont know about that, but I know that my refurb has better sound output through the headphones and the gps locks in ten seconds without any bandaids. First phone was a day 1 captivate.

Highly doubt that the battery life is that much better. Its pretty much the same phone just with a different build date. It is all perception in my opinion with the possibility of better battery stats

2 days and counting since last plugged in, with GPS and Wifi on. Battery only half empty.
On the old one, with GPS and Wifi off, I rarely if ever made it two days on a full charge.
Definitely not just perception - something is different. Could be the 2.2 build vs 2.1, instead of the hardware.
I also get much faster GPS lock. 10-20s vs 3-5m. Yay, me.

I believe we have a winner ...

I found the stock 2.2 has MUCH BETTER battery life than any other version/ROM that I have ever tried so far.
I flash the Rogers 2.2 stock ROM and I can run the phone 24 hours with ~30% battery left. I use K9 mail and receive 30 - 50 emails a day and poll every 5 mins. No WiFi, all 3G data access. The Rogers stock ROM use JL1 modem.
For comparison, I'm on FireFly 3.0 right now and the phone is dead after 12 hours. JK4 modem is used here and WCDMA 850 is enabled.
I can't see what triggers the battery life, but so far I've gone back to the Rogers 2.2. stock ROM twice because it has unbeatable battery life, albeit how much it sucks feature-wise.

Is it just me or is the Thunderbolt battery life... kinda good?

So, I was well informed from many different sources that the biggest drawback to the Thunderbolt was the horrendous battery life (people complaining in the 4 hour range). I came from a Samsung Fascinate, which would most of the time get me through the day, but just barely, and the Battery Use was almost always 70-80% screen (even at the lowest brightness). I primarily got the Thunderbolt for the possibility of 4G tethering, so the first thing I did was buy an external battery charger pack (extended battery was sold out).
Well, I've had it for a few days now and despite geeking out on the phone, tethering whenever I can, using it probably more than my Fascinate, I haven't had any issues with battery. I pulled it off charge about 8am this morning, it's currently 9:45pm, I've been using it pretty heavily all day, tethering on the train to work, using it at work, and using it the whole train ride home, and it's currently at 33% battery. 6:18:00 Awake time. Where is this horrendous battery life I heard about?
I'm not using any battery saving utilities (Juice defender etc), have it set to Auto Brightness, just letting it be on WiFi when WiFi is available. I'm using the bone stock HTC Android 2.2 that came with it, not root etc.
So far this phone has much better battery life than my Fascinate and I'm pretty impressed, especially since I believe it has a slightly smaller battery. If I check battery use today, it's 59% Display, with the next highest being 9% Cell Standby.
I haven't used it as a 4G hotspot for more than maybe 30 minutes at a time, but even then it doesn't seem to die too quickly. Am I just missing something that other people are doing that drains their batteries like crazy or is it just that I'm careful about not using stuff the indiscriminately uses 4G for no reason? (I removed all the auto updating widgets like the Friend Feed etc).
Anyone else had a similar experience?

Ummm, yah, well, it's just you...
JK... the battery is ok for me I haven't had it die on me yet but when ever I drive it goes in the charger so I'm sure that adds up.

It's you.
Seriously though. Go to any one of the Thunderbolt forums or read any Thunderbolt review and you'll see the battery being discussed prominently. There is definitely an issue with it. Who knows what it is though..
The thing that really bothers me is the battery isnt consistently bad. Like the last two days Ive gotten 24 hours of use out of my phone. Normally that's unheard of.. but next week something will happen and it will be back to being dead within 6-8 hours with barely any use.

You are correct that this issue is oft-cited in regards to the TB. However, I think the 4 hour data points may be slightly exaggerated. I wound up buying the oem extended battery because I wasn't make it past 6.5 hours with regular use. I travel pretty far to get to work every day, switching between many towers over the course of my commute, constantly going from 4g to 3g to 1x and back. Besides the screen (which will be the biggest battery drain on any phone with a modern touchscreen) data should be your next highest drain, and the biggest variable you are capable of tweaking to change your battery performance. My 6.5 hour experience was with a pretty abusive data usage scenario, and I don't see many people inflicting much more upon the battery in actual, real-world use. That said, with the extended battery, the TB has the best battery life of any phone I have owned in the last five years, and I couldn't be happier.

I'm getting about 12 hours with pretty heavy use. Running BAMF 1.6.2 with kernel overclocked. I'm pretty happy with battery life...it's just as good as it was on my droid incredible.

I have learned thru experience that all HTC phones with 4.3 inches screens are bad at battery life. When I say bad, that's comparing it to a smaller less powerful device. But take in account all it does and to me battery is ok. I mean the HD2, and EVO when I owned them were battery hogs. But I always had a charge. Ppl want bigger and faster phones,Well there's a trade off until battery technology catches up, the bigger phones will consume more battery. Its like saying I want a better car more sporty and trendy but I don't want to pay that much. Not goin to happen.

With just 3G available to me and using everything stock...I get slightly better battery life than I did with my incredible that was on CM7. Compared to a stock incredible, much better. I'm a bit scared for when I do get 4G seeing all the posts though =)

Rooting gave me an extra 2% per hour usage. I can go 15 hours and still have 40% left on my battery. I'm happy with this battery.

Thunderbolt has better battery life than my Samsung Epic had. Stock, my battery wasnt all that great. However, changing some settings and finding a suitable kernel has helped with my battery life.

I have had the same experience. Coming from a Fascinate, the Thunderbolt is so much better on battery life. Mind you, I do not live in an LTE area. This is what I do:
- Juice Defender (Balanced settings)
- Brightness - half way
- GPS only on when I need it
- Wifi on almost 100% of the time (at home and work I use only wifi)
- Non-Rooted
I even have 100+ apps installed including leaving Google Talk and Yahoo Messenger on almost 24/7. I have about 8 or 9 widgets as well. Most that pull info.

The terrible battery life comes when the phone tries to hold a bad 4g signal drains the battery at an insane amount. If you're in strong signal expect much better battery life but because 4g is so new I expect a lot of people to be in areas with low 4g signal as Verizon has not even turned up 85-90% of the towers past 45% power.

I've had the TB for 3 days now and am coming from a rooted Eris (running xtr rom). I have noticed that with the same amount of usage I am also getting better battery life on the stock TB than I did on my Eris. I am in an area that does not have 4G so I have that turned off.

I'd love to see some sources backing this info up.
When I bought my TB I left the store with the extended battery in. The battery easily lasts me all day. After reading all the complaints about how bad the stock battery is I decided to try using it and I'm actually surprised by how long it lasts. I was expecting much worse. It's easily lasted me 8-12 hours with my normal everyday use. I'm going to stick to the stock battery from now on. I was getting annoyed by the heft and bulkiness of the extended battery. My phone feels so sleek with the stock one.

Yeah, I'm with the "it's just you" crowd.
Pretty bad battery life for me here in NYC (plenty of good 4G around).
Not a heavy data user (less than 20min browsing per day).
Not a lot of long calls.
Accounts update once every hour (FB, 2 email accounts).
Brightness at min.
No video playing, no music playing.
No speakerphone used.
Rooted, BAMF 1.3.2
GPS and WiFi rarely on at all.
I'm lucky, --LUCKY--, if I get like 6 hours out of a fully charged battery.

Just curious, why are you still using BAMF 1.3.2?

running Bamf 1.6.1 and Imoseyon Lean Kernal set at 1.4Ghz with SetCPU on Smartass, along with ATK set to kill every 30 mins(oh I know they are the devil, yet my battery life is always better with one, so no comments about how they are bad.) I also always have 4G on, and usually fluctuate between -82 to -94dB in signal strength, and wifi is never on, as my home network is strained enough as it is. GPS is always off unless I need it.
I also use WPClock Live Wallpaper at the same time.
Yesterday I was at 18% with 2 days since last plugged in.
Of course I also calibrated my battery, after flashing Bamf 1.6.1.
I use my phone alot for facebook, angry birds, browsing the web and a crap ton of texting, I probably hit near 1000 text a month, I know that isn't what the high school brats are pulling, but still, for me, that is insane.
On my Evo 4G, with 4G off, I could hit 3 days running CM7 underclocked to 750Mhz max. That was with a bigger battery as well.
I am very exited for CM7 to go into a beta, or nightly stage, and the kinks worked out, as I am sure with 4G on I can hit near 3 days with the Thunderbolt as well.

Update your sig, brah. Still says your running Tesla Coil.

Overall battery life is a lot better than my cm7 Incredible, and on mostly standby it lasted quite awhile before I had to charge it (I couldn't use it for a few days because vzw wonked up on activating my TB somehow), so it lasted almost 3 days with only occasional data use/seeing if the phone was working (I couldn't send texts or make/receive calls, but my data was working)

Engadget lies about Charge battery life

I purchased the Droid Charge based on the Engadget review of the device. In particular, I wanted a device that could get on the LTE network AND have great battery life. This excerpt sold me:
When it comes to battery life, there's no competition. The Charge blitzed through a full day of what we'd consider typical use, coming off the charger at about 9am and not getting slotted back in again until 9pm the next night. Yes, you read that right, two working days of what we'd consider average use with GPS and WiFi on, taking pictures and videos, all powered by a single 1,600mAh battery. Granted, we weren't running our performance benchmarks at the time, but we were hammering the LTE antenna to get some speed results.
I expected to get, at a minimum, a full day's charge using LTE on this device, considering I live in an area where LTE isn't hard to come by (Los Angeles). Alas, I was sorely disappointed when my battery drained within 5 hours with minimal use. 5 hours!!! How can Engadget claim it will last for two days and that "there's no competition." It's totally misleading. The Droid Charge has a serious battery issue which nobody can seem to get to the bottom of. I even tried installing the latest Gingerbread rom to ameliorate the issue, but to no avail. Has anyone gotten a full day's use out of the device when on the LTE network?

I just got back from a full day's use on 4G with GPS on, WiFi on and Exchange and Gmail pushing mail as needed. I did not, however, text at all. One of my pages has an IP camera app that updates three feeds (snapshots) at least every five minutes. I am in a pretty consistent 4G area except when I'm at home (Philladelphia suburbs by my home is in a geographically challenged location)!
The phone just turned off as it dropped below 2% so I can't give any battery stats; I've been following the battery recalibration procedure listed here.
Keep the faith...you may not reach two days but you should be able to get a lot more than 5 hours!

I am in a pretty consistent 4G area except when I'm at home (Philladelphia suburbs by my home is in a geographically challenged location)!
The phone just turned off as it dropped below 2% so I can't give any battery stats; I've been following the battery recalibration procedure listed here.
Keep the faith...you may not reach two days but you should be able to get a lot more than 5 hours!

Out of curiosity, which ROM are you using to get this kind of battery life? I just installed the latest Gingerbread leak and my phone is leaking battery at a rate of 15-20% per hour. I saw that re-calibration post, but I'm wondering if I can simply charge my phone to 100% and place the same ROM on top of the one I already installed. Just want to make sure I don't brick my phone.
Any thoughts?

If you wondering if you can just replace your current COM with the same one you are using by just replacing the files on the SD card then yes you can. If you're asking about re-flashing the same ROM over it again without wiping during the calibration then you can. It shouldn't harm anything.

I've already installed the latest Gingerbread ROM and updated all my apps and widgets on the device. Can I now charge the device to 100%, bump charge a couple of times (per the instructions in another post on the board), and then restart and wipe the battery stats in recovery mode? Or, do I have to charge to 100% and then completely reinstall the same exact ROM on top of the one I just installed?

Stockmoose.
5 hours? That's questionable that you only got 5 hours with minimal use. No Engadget did not lie, and until the 1700 mah phones are released the end of the month, there is no comparison.
Only with Altered Beast and heavy use was I able to kill the battery in under 8 hours. So I would chalk it up to a bad battery. Not everything is perfect.
Gingerbread is a leak, so trying to compare it to the stock rom does you no good.

You can wipe the battery cache without having to re-flash everything again.

Agreed, I was heavily influenced by the Engadget review and was seriously disappointed when I struggle to get a day's worth of usage out of the stock ROM on 4G.
The Gingerbread leaks have some serious battery issues. I reccomend flashing Humble v1.3 (Froyo) and undervolting. Best battery life by far. I can hammer the LTE radio for a few hours straight.
As a side note, all of Verizon's current 4G Android offerings have awful battery life due to having the dual CDMA and LTE radios. That being said, the Charge evidently has the best life out of the three of them. Future phones (when Verizon dumps CDMA altogether in favor of LTE) will have way better life.

Curious while running Humble v1.3 and undervolting which kernel are you running atm. And second what undervoltage settings are your using atm currently so yo uare getting random reboots. Reaosn I ask is I just flashed v1.3 this am and updated to Imnut's newest OC kernel but have left it alone right now without touching any voltage settings. So any input would be great and I'd like to set mine nad check it out to see if I can get even better battery life out of it. Thanks

Pro tip: Never buy anything based solely on one review.

This should help.

I get about 12 hours with minimal to moderate usage throughout the day 4G, wifi/gps off for the majority. I might have to try this bump charging, though. Would be incredible to get a solid day out of this thing.

9 hours of using my phone to check XDA post, playing bubble buster, and texting and my phone is at 77%. Only thing different on my phone is i'm using SetCPU to undervolt. But even with that. if you are only getting 6 hours with minor use. There is something wrong.

I just did a solid 36 hours by staying on my home Wifi almost the whole time. I'm using Gummy Charged 1.8. Before everyone starts calling bull----, I probably used the phone a total of 1 hour over that period of time.
Normally, it lasts 14-18 hours with only Exchange mail and an hour of gaming (no facebook, social networks, etc.)
If I recall correctly, battery life was an issue with the gingerbread leaks.

I did the battery charging cycles as mentioned above and erased the battery stats last night. Now I'm down to 20% after 6 hours of light use. That's pretty much the same way as before. What did I do wrong?

Not a chance I'll say bull**** that is for sure. When leaving the device on Wifi battery life will DRASTICALLY increase. The radio in the device is what is eating it up. If you want to conserve even more battery I've found and don't ask me why if you actually turn off Mobile data and then turn Wifi on it will help even more.
Ran a test last night and with over 7hrs on Wifi it dropped on 5%

I've gotten 24 hours with about 20% to spare going in and out of Wifi and 4G. I had 3 gmail accounts sync'd to the phone and I probably streamed about 20 minutes worth of music using Google Music. But, I probably used the phone for a combined total of 1.5 hours over that period, and it was a slow day, so I actually didn't get many emails.
I think I was using one of the Froyo Gummy ROMs.

I don't think it's very fair to use custom ROMs and then complain about battery life. Was your battery life lower than 5 hours on the stock ROM? Did you even use the stock ROM?

Try reading more than skimming the OP. He implied that he started stock there, and about 3 posts down said that it was ridiculous that even the stock ROM couldn't get 5 hours.

My apologies, I misread his second to last sentence in the OP.
Either way, 5 hours is not normal and I wouldn't blame the Charge just yet. Not sure if you guys have official 2.3 yet (I'm a Thunderbolt owner myself), but I know the Froyo ROMs on the TB have a very noticeable increase in battery life compared to the Gingerbread leak builds.
I get about 6-8 hours of heavy use on my 2.3 ROM on the TB. Probably closer to 13+ with Froyo.

bad battery life??

I switched from a highly modified DroidX (which I still own) to a new Charge recently (which I absolutely love).
The X had GB flashed with Liberty ROM and the battery life was really exceptional. It did increase when I swapped from froyo to GB, but I don't really remember how much. Using the VZ extended battery (the small one that fits into a stock case) I easily got a full days use out of it with GPS always running, weather updating every 30 minutes, gmail running push and Bluetooth on quite a bit. I can't remember ever once having to swap out the battery before I got home from a day at work.
With the Charge, on the very first boot (before it was even activated), I opened it in odin and flashed to gummycharged 191. The thing runs totally awesome, fast and fluid as hell-completely lag free and has never frozen up once. It blows away the X in every way except battery life.
Today, I started on a mugen 1800 battery and ran that until it had 2% charge left. That took about 4 hours running EXACTLY THE SAME apps that I always ran in the X. I then stuck in an aftermarket 1800 battery and ran that one until it was totally dead also before I left work.
Other than the battery life, I am 100% totally happy with the swap from the X to the Charge. I have three extra batteries and an external charger for the Charge, so having to swap batteries etc is not the end of the world, but I am wondering how much better the battery life would be if I swapped to a GB ROM at this point??
I am open to any/all suggestions at this point......

to add to this, I am running LPP+ launcher with the identical screen/widget setup as I was running in the X.

There's three things you need to be aware of for battery life for this phone:
1. Your kernel - This affects your battery, not the ROM.
2. The screen - The screen is awesome on this phone, but unfortunately it is a battery killer, this can be solved by turning off auto brightness or downloading the Screen Filter app. The screen is also the main draw for the battery in terms of drain.
3. The 4G LTE Radio - this is the largest difference between your last phone and this. If you live in an area where your LTE is spotty, I suggest turning off your LTE and leave it at 3G CDMA. An easy way to get to the toggle is to download the LTE Switch from the Android market. The reason the LTE destroys the battery is due to the fact that your phone is constantly searching for an LTE signal, thus draining the battery faster than a non-4G phone would. If you're in a strong LTE area, it shouldn't affect it much, but turning off LTE does help the battery in most cases. The LTE radio is the second main draw of battery power.
Finally, be sure to remember to wipe your battery stats after flashing the new ROM and fully charging your phone to 100%. Hope all this helped!
EDIT: Also be wary when flashing to one of the Gingerbread leaks. People have been getting mixed signals in terms of battery life, since the leaks aren't exactly stable. I tried out GB for awhile, but wasn't too fond of the instability that Froyo still offered, so I flashed back after a week.

I turned off the auto brightness setting immediately. I run it on 25% most of the time, i only turn it up when I'm outside.
I have been thinking about trying a few different kernels to see what difference that makes, any recommendations as to which one might be best?
I did calibrate the battery after flashing the ROM.
I do have the 4g switch (and I'm in a 4g area) but I haven't tried running for a day in 3G. I think I will try that tomorrow and see what difference it makes.

Kernels–if you don't care about overclocking I recommend imnuts non–OTB kernel.
