Ok, I have been flashing for a few months trying to optimize my phone. My last rom was serendipity 6.2, with sp 59 and jl2. I restored to stock (bc I wanted to try something else and hadn't done that in a few weeks) my battery life on serendipity was atrocious.. 6 hours with medium usage. (hardly any calls or messages, looking things up or reading xda briefly) . I spent today on stock, after about 20 hours of light usage I am at 60% left. Now I did flash with a full battery serendipity, wiped battery stats and cleared cache and after several charge cycles and a few days battery life was still awful. I was about to get a new battery. Now I don't mean to single out serendipity, I've had bad battery life on paragon, dilli, and a few others (this time it just got unbearably bad), but why should battery life be so bad on custom roms? Am I alone on this? I hesitate to flash again bc I'm loving having a phone that won't die if I touch it, but I miss the functionality of the device with a custom 2.2.1 on it. Advice or opinions please.

I'm having the same problem. Everybody keeps saying they've got excellent battery life and what not with custom roms but mine doesn't seem so good. Wifi is off, I've wiped battery stats, I've used the rom for several days letting everything get situated before I begin thinking about if its good battery life or not. Maybe I'm just expecting too much or I watch my battery a lil bit too much, idk it just seems pretty bad. If I stay on the internet for 20 minutes I've already dropped about 3%

The normal Batt live on this phone with normal use is between 12 to 16 hours
I'm thinking part of it may be psychological and part may be usage.
Psychological in the sense that I have an expectation of an improvement, practical in that with my stock rom I haven't reinstalled certain apps like xda and pulse where I spend a lot of time reading and thus using the screen.
That being said I was still experiencing drains of 8% or more per hour when the phone was idle, wifi and gps off.
There is a way to check the cpu's time in each state, but I can't remember where the file is. If someone can, please let me know. I'm curious if under the custom rom my phone wasn't properly scaling down.
I'll probably flash something new tomorrow morning unless I see something shiny and new in the dev forum.

So 6 hours seems a bit low then? Could it just be a cumulative effect of flashing rom on top of rom with restoring to stock?

Yeah 6 hrs does seem a bit low. There are many things that can contribute to it. If you are bouncing between H and 3g on a custom rom will drain it like crazy, I had to disable H and stick with 3g and that helped. could also look at OS monitor to find what is running in the background.
Ok, I did notice that recently I was jumping between h and 3g. I was experimenting with some of the new modems. Should I try finding a better modem for my location?

I would try others, as well as disable H in the hidden menus, and see how it fairs
@ zelendel.... so by H i assume you mean data... i see alot of back and forth when data is on. i know when data is off i'm still using wcdma from the gsm status, but it doesn't show the 3g icon.
i need my data because i'm from the states but living in australia and alot of my comunications are thru email/facebook.
when i look at battery usage i see rarely more than 5% from cell....usually 90 something from display ( i fiddle with it alot).
can't expect too much cause it's a powerhouse with a tiny battery........
for me the big Q at present is... can we top up the charge regularly or is it always best to let a full cycle run? if i knew it was fine to keep it topped i'd stay 50%+ most of the time i think................
It is not great to keep it topped off. The lithium battery will wear out faster and lose charging capacity over time. this process is sped up the more time the battery spends at a high charge

Visit the Samsung web site and read the battery specs for the Captivate. The stock battery is only rated for 5 hours and 50 minutes of active phone use (which means the display is active). In sleep mode (display and other features of the phone are shutdown) the battery is rated for up to 300 hours (12.5 days).
I have NEVER seen a stock Captivate last for over 3 days in sleep mode. As for active phone use (display is active) my experience with several of the custom ROMS (Cognition, Paragon, Andromeda, and now my favorite, Continuum) is that the battery life is either on par with the stock ROM, or exceeds it. The kernels on some of these custom ROMs are more efficient than that of the stock ROM due to the many tweaks and cleaning up of bloated apps and code by the developer.
I can't bring myself to keep a stock ROM now that I have used some excellent custom ROMs like those I name above.
As for flashing custom ROMs and seeing fast battery drain goes... I have had that experience with those I listed, but usually I was able to resolve the issue by ensuring my battery was at 100% (meaning showing that amount both on and off) and reflashing, or finding the cause of the high battery usage and going from there (e.g. I have had to reflash modems). Another thing I do, mainly out of habit from compiling code and deploying it in dev and test environments, is to make sure that I am working from a known good baseline ROM before flashing a custom ROM. In this case I always return to the stock ROM you can flash through Odin One Click. That way if you have battery problems after flashing a custom ROM you can have a good idea as to what is causing those problems. This is, of course, just a matter of personal preference. Some have repeatedly flashed one custom ROM over another with no issues. YMMV

No what I mean is disable HSDPA I think is the term lol. Sense you go back and forth I would say to disable that and just use 3g only.
If you don't know the code to get too the menu download sgstools it has the hidden menu keys.
Sorry but where can I find the hidden menus?

I am the opposite, I got horrible battery on stock. Could not even make it through my work day without it dying on my way home unless I charged it midday. Now I am running Serendipity 6.2 and unplug at 7:30am and it is now 8:30pm my time and I have 30% remaining....
I have also tried other customs roms with noticeable improvements in battery life over stock but for me Serendipity gives me the best performance and battery.

Could I have a faulty battery? I rooted and rommed cuz of my battery life being terrible but It still is bad

I had the exact same issue as you. I tried Darky's 9.3 first, then Serendipity 6.2, then Cognition 4.2.1. Each had major battery drain, meaning 6-8 hours with moderate use, and even without any usage it would drain 25% over 3 hours.
Use One-Click to flash back to stock JF6, then immediate do a Master Clear from the One-Click program after it has finished booting. Obviously move everything to an external SD or the computer prior to all of this, and make sure the external SD and SIM are out when flashing.
My battery has lasted for 14 hours today, and I'm only down to 54%. This is with about 1hr 20min screen on, ~30min voice calls, and always connected via 3G/H with background sync on, weather widget, and moderate web browsing.
Current setup: Serendipity 6.2, Speedmod K13C, JK4 Modem
Trying again
I couldnt keep myself away from custom roms, how i missed tethering, the custom theming, non marketplace apps and so much more...
Im trying Dilli's 7.1.1, bump charging at the moment...
Last night I drained my battery to 5% when i finally fell asleep... 6 hours later it was at 4%. Finally it drained and would not power on at all. Not even the backlights. Plugged it in for an hour and thought to take the sim card out so i would have a phone for the hours it would take to charge. When i plugged it back in the phone jumped from approximately 10% to 40% charged...
Oh well.
I have also been bouncing around flashing diff roms like crazy. I have to say though, I am using Continuum v4 with Hardcores speedmod Kernel K13D. I have been doing pretty good on this combo. Lasts for most the day with normal use.
i'm thinking about getting the HtC inspire 4g. hows the batt life if you turn off 3g, wifi, push mail, gps, and set brightness to 30%?
I don't turn anything off and have been getting a full day with 6+ hours of screen on time. Running gtg's ace Rom and capy's kingdom. Thoroughly impressed with the gingerbread Rom performance.

hi, newter.. thanks for replying. thats impressive. so i guess that if you turn off wifi, 3g, push mail, etc, i'm sure batt life would be 2 days with moderate use.
also, can you tell me how i can unlock this phone on tmobile?
Rooting gives sim unlock.
Just use the hack kit. It will sim unlock, root, and s-off for you.
I should note that my usage may not be typical as I use few minutes using it as an actual phone. Web, text, xda, music, some email, and a few games are what I use it for.
I was able to pull 3.5 days out of Cyanogen 7.0.2 with the LorDmod kernel and Pinky Undervolt scripts. I have K-9 set to check three mail accounts that get a fair amount of traffic with push notifications, leave it in HSUPA mode, and my brightness hasn't budged off "automatic".
I'm currently trying dilligaf's AOSP+CM hybrid with the Pinky Ultra Undervolt and have been getting some really good results so far. I'm currently at 93% after being on the battery for 12 hours.
EDIT:
Completely stock, the battery wasn't that bad but it would need to be plugged in to the charger at the end of the day, generally lasting around 15 hours.
what does unlocking the sim do??

Allow the phone to be used with another carrier.
i can go three days with three hours of screen time with TPGB-CM20110509, actually a prior version, but this one fixes an MMS problem, and current widget throws up similar numbers, so well see.
Using custom ROM packages greatly trim the fat (bloat) off and drastically increase efficiency equaling much better battery life...Rooting / flashing ROMs has been the greatest feature coming from jailbreaking iPhones...I'd never go back
Streaming, all day. I get about 6 hours .. else with internet and games and just instaling uninstalling and general playing around I get 10 plus hours.. I never use it as a phone.
with everything like described in the OP, ive gotten 24 hours out of the phone with phone calls here and there. if you turn off all that stuff, you can eek out 1-3% battery drain/hour. it's pretty good and almost always lasts me the whole day
Running stock out the box i had 12-14 hours of battery life. Loads of texting through out the day and playing a few games, on the web, gps here and there, and some phone calls. I have my brightness at 0% if not at 40% during the day with everything else off unless I need to switch it on for something.
With custom rom I get around the same battery life but with heavier usage. Texting all day long while playing games for a few hours, then theres navagation use, phone calls, emails and notifications from apps. So either way you should get good battery life.
Mine got better after I rooted and installed the Saga ROM.
Saga isn't being updated so I just installed Ace.

hi, numpangx, thanks for replying. lets say that i install gingerbread on it and turn off wifi, push notifications, gps, weather, play no games, and reduce brightnss to 30%. but make calls. do you think i would be able to get 2 days of batt life?

wow helushune thats excellent! 3.5 days on the htc inspire with that droid rom.. i should install that then. so with heavy use, calling for an 1.5 hours, playing a game, and nothing else, i'm sure you yourself would get 2 days batt life? am i right?
My stock Inspire goes from about 9 am to about 3 am with heavy use, I end up with 15% -/+ at the end of the day.

One of the biggest killers of the battery life is the massive screen and backlight. I haven't done any heavy usage testing as I'm seeing what kind of battery life I can get out of dilligaf's AOSP+CM hybrid rom with an undervolt script.
I did make a few phone calls and I think I played Rocket Bunnies/ran a few speed tests when I got the 3.5 days. There's also a pretty big dip around the 60% mark where I re-installed CM and flashed a new kernel as well. But I generally use my phone to respond to text messages and email and that'll kill the battery faster than spending the equivalent time making a phone call.
So i got the charge a couple of weeks ago. I had the thunderbolt before it but then i switched it out for the charge just because the thunderbolt was kinda heavy. Now i have terrible battery life. I am on stock rooted EE4 and have tried everything short of throwing the phone at the wall. I have 2-3 bars of 4g signal usually (metro detroit). I have tried AC Altered beast, tried gummycharged, tested my own rom, used kangfucius, PB&J Time, and VOODOO, all to no avail. I leave at 7 am and come back home at 3 pm and the battery will be down to its last 5 percent, running on fumes. I even turn off mobile data or i put it on airplane mode and that doesnt even seem to help. MY THUNDERBOLT GOT A WHOLE DAY EASILY WITH IMOSEYONS KERNEL ON 4G but the charge with supposedly better battery life is worse?!?!?! Any advice?
Let it go through a few Charge cycles (heh heh). I went about 12+ hours or so with fairly heavy usage yesterday. Always on: 4G, Bluetooth, GPS. Running: EE4 debloated, PBJT kernel, Voodoo enabled, automatic brightness, 2min screen timeout, 2 GMails, facebook, 2 emails, NoLED, etc. I even tested the mobile hotspot to dl a few big things (free PSN goodies FTW).
That should give you a good idea what's using up my battery. YMMV.
Mine is new and I think it also needs a few charge cycles, getting better but my thunderbolt was terrible for a month before I pushed 10hrs consecutively

I think the "great" battery life is only on Samsung's slow stock ROM. I feel totally duped that I bought this phone for great battery life when its no better than the TB.

He's had the phone for several weeks! My guess is that he's been through many a charge cycle!
I have had my stock ee4 RUNNING with wifi, gps, and interminentant 4g for twelve or thirteen hrs now and just got my battery warning. I have been reading forums all morning, and made several phone calls. The battery seems very good. I think you should check your bat. use its probably mostly screen use. I think that is everyones highest usage

You assume he's let the phone die, turned off the phone, let it power all the way to full and then repeated this 2 - 3 times.
which is an asinine assumption seeing as most people don't let their phone die before charging and don't turn it off while charging - my guess the number of full cycles its been through is 0.
Given that he's tried 3 ROMs and 3 kernels, that gives 9 different possibilities. Using each for 2 days, which isn't really enough time to fully judge battery life, that gets us to 18 days, nearly 3 weeks. I'd say you have to have your phone with a ROM/Kernel combo for 3 days before you can get a sense of normal usage/battery life as the first two days, you'll still be setting stuff up the way you want and tinkering with it. The 3rd/4th/5th days is when you get a true sense of battery usage as by then, you should have most stuff setup the way you want it and your normal usage should be more consistent.
I haven't run out of battery yet but the longest I have kept it off the charger is 15 hours. I leave the radio on and get 4g mostly, stock EE4. I use my charge to listen to music and make a few calls/texts during the day. Screen seems to be the biggest drainer, nothing else comes close.
Not seeing bad battery life on my charge.... Running gummy 1.5 + pbj time kernel + voodoo lag fix + voodoo system fix... heavy use im getting about 18 hours on one charge

Battery sucks on both the Thunderbolt and the Charge. I'd forgotten how bad the Thunderbolt was until I switched back from the extended battery to the stock.
Any comparison of battery life must include a thorough discussion of how you use the phone. What apps and services are running in the background and ideally some screen cap of the battery use screen. Without that kind of reference your definition of light, moderate, or heavy use is meaningless.
I think both phones have similar performance, it's the price we pay for that 4G lightning bolt.

yep every day iv'e charged it so it's gone through at least 20 cycles.
And i'm running stock EE4 and PBJ kernel (not the overclock one) with lagfix not enabled but it's the voodoo version. Does voodoo save battery?
oh and i have a few apps running in the background like google voice and fb but thats about it. I dont have skype or any of that just fb and google voice. the rest of my apps are mainly games and stuff like pulse that doesnt run in the background. my display is on about 20-25 percent. some days i put it on airplane mode sometimes on mobile data off but even then, the battery is either close to dead or has about 30% left. Keep in mind thats only 7 hours no use at all and that only leaves me with about 2 or 3 hours of actually usage. and the only thing that i do then is browse the web. maybe a 1 minute voice call but that is it.
try going into your settings..accounts and sync....and turning off the auto sync option and then turn off all the accounts you have syncing..I see no reason why google has to constantly sync my contacts when there not changed and use my battery up..you can always do a manual sync and turning the auto sync off hasnt affected my FB updating.
Also on any kind of social updating widget or new ticker you can adjust how often it updates itself too. Again unless your just dying to have it updated all the time then expect the battery to drain faster when it updates. Also when I am not using my phone I turn the data, GPS, and wifi all off. I have been happy with my battery performance and Im running just like urs with rooted PB & J kernel but EE4 stock..I have lagfix enabled though

Yeah, I never get the turn off your data and everything that makes a smart phone smart approach, but to each his own. Just depends on your priorities.
As a 100% exclusive google voice user (for calls, texts, voicemail) I have to leave data on, or I don't get my SMS and voicemails. I don't want to have to manually check for emails either.
Things like twitter, facebook, etc are all optional for me, so I make them either manual or long intervals on the checks for new posts.
Words With Friends is an absolute battery whore. It defaults (at least it used to) looking for updates to your games EVERY FIVE MINUTES...that's insane, and all you have to do is watch the darn thing try to update games to see how much radio it's wasting, takes forever. Turn it off. LOL
I get all my texts and what not with the data turned off....and when I go to use the phone for anything I turn it back on and use it for whatever...I dont need the instant gratification of getting the email the second it is sent. I guess some people need that feature. Once the syncing is not running all the time from your various apps, then leaving the data on shouldnt drain much battery at all. I am still quite a newbie at this stuff so if I say something stupid please excuse me

Oh, no, nothing stupid at all, that's why I said "to each his own" and "just depends on your priorities." We all use our phones differently. Do what works best for you.
IF your texts are via Verizon SMS, that stuff comes in over the voice channel, not data, so it's not impacted by turning off data. Google voice comes in over the data connection, so no data means no texts! If you're in a wifi area, you could turn off mobile data and you'd still get GV stuff, but no need to since wifi will take precedence over the mobile (cellular) data anyways.

No, voodoo doesn't save battery in itself, but some of the other changes in that kernel increase battery life.
i still think you need to swap that phone out. You're working too hard to get decent battery life, and shouldn't have to.

I was able to get a crazy amount of life out of the G2x! Anyone else able to get some times like this?
When I first got the phone it would only get about 4 hours.

I have tried virtually every ROM and kernel combination for the G2X and for my phone and usage pattern I have had the best luck when I returned back to CM7, currently RC1 without OC/UV kernels, without SetCPU/PimpMyCPU, and without Juice Defender, or any similar such programs. My gains appear to be achieved by better efficiency with the screen off. The only modification that can be responsible other than CM7 itself is that I have the phone 2G only unless I need 4g at which times I turn it on manually. I think this is the actual cause of most of my better battery life.
Recently I went 32 hours of light usage (maybe an estimated 3 hours of phone calls and 2 hours of actually performing some task in Android) and was at about 35% battery life (although I believe battery percent is totally meaningless on this or any GB Rom for the G2X). I can easily make it sun-up to sundown with moderate to heavy usage unless it involves lengthy playing 3d video games or similar cpu/video intensive tasks.
When I first had the phone (completely stock) the battery would run out before 8 hours even if I didn't use it at all. I think I was getting great battery life with the AOSP ROM (Faux) and Eaglesblood ROM without modification. I am came back to CM7 rather than those others for purely aesthetic reasons.
My conclusions are merely based upon extensive trial and error and subjective impressions. I am not an expert at anything, except perhaps backgammon, lol
2g only is not a fix in my opinion. I purchased a 4g phone for a reason. The software and drivers are still an issue. I get a solid day (12 - 16 hours) out of a single full charge with 3 email acounts checking every 30 min. Surfing the web and a little game play for fun. The screen is the biggest draw on the battery. My battery monitor shows a direct corolation to battery draw and the screen on.

I understand your point, but how often are you actually using 4g. It is not necessary for syncing email or other background tasks, in fact on my phone Pandora runs the same on 2g as 4g. And when you do need the performance of 4g it is 2 clicks away, one swipe to pull down the notifications and another to toggle from 2g to 4g. It connects in about 10 seconds, for me anyway a shorter period of time than it takes me to figure out what I'm doing. 4g appears to be the biggest battery draw with screen off. If you use JuiceDefender you can program it to turn on 4g whenever particular programs are launched.
You are right about the screen it is certainly the biggest draw with screen on. I run a bike computer with gps program. I run it with screen at full bright constantly on, gps running, plus using whatever small amount of use the program uses to operate. At this rate the battery runs out before 4 hours are up.
Oddly making phone calls appears not to drain the phone at all compared to other activities. I've taken my phone of the charger and made a 1.5 hour phone call and hang up and the phone is still at 99%.
23 hours and counting on this charge...
i can get that time on my stock rom one time my phone lasted 1 day 15hrs on stock rom.

I have no doubt, there is nothing inherently wrong with the stock rom as long as you root it and get rid of the bloatware. Getting bad battery life is more a matter of something being wrong, instead of a particular rom being right.
I don't really understand the battery info built into Android, my uptime right now is just over 16 hours and I am at 25%. Which is good as anyone can expect with normal usage. But what is confusing is the usage breakdown, it lists most items at exactly 19%, Cell Standby, Wi-Fi, Dialer, Android System, and Phone idle. Voice calls is the only other item at 6%.
What the heck is Dialer doing with 19% of my battery!?!?
16 hours so far with 20% left.
8 hours of that was while I was sleeping.
While there was some screen-off time for the other 8 hours, the tasks I was doing included redownloading ALL of my apps manually, applying themes, configuring widgets, browsing xda, email, light texting, and a couple short calls.
I am running CM7 with stock kernal. I have like 40 widgets running (probably an exaggeration). I'm running Juice Defender set to disable data/wifi when screen turns off, and enable it for 2min every 15 min. I also have setcpu running. I increased the min to 456 instead of the default 216 because it seems to keep me from experiencing the black screen of death when I leave it higher. My screen-off profile is 456/456, and my in-call profile is 608/608.
Overall, considering that I keep all syncs set to auto so I get instant notifications of gmail and sms, and it takes all of about 3 seconds to turn the data/wifi back on when I turn the screen on, and I don't have to constantly go back and forth messing with 2g/3g. I am extremely pleased with this phone now.
Been unplugged since I woke up this morning...13H 57M and have 40% left.
That's sending many texts, tweets, and using the GPS app for my round of golf today.
currently at 2 days (actually 1d, 23h, 44m) and I still have 30% left. I would say light to moderate use.
Currently running cm7 on nightly 65 with the stock kernal. No setcpu/pimpmycpu or any juice defenders.
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!

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.
