Battery life on custom roms - Captivate General

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.

Battery is Great on the Tunderbolt

Put it to a real test. Went to the grand prix today in st. pete.
Didnt even have a full charge around 90%. Had 4g on all day.. Brightness all the way up. Facebook , twitter, and 2 e-mail accounts running in the background. Took tons of video clips and tons of pictures, and streamed music through the bluetooth on the way home. As I type this its been 10 hours since it came off the charger and its at 50% battery with all the same items running.
At 1st I had very very bad battery life. But after using it for a few days and then doing a battery pull (read it would get better after all this) it has been working great, with the same or more use then I was doing the 1st few days of ownership. Just wanted to share a postive experience on battery life since I keep hearing and reading so many negative things.
Edit: Thunderbolt not tunderbolt LOL
Thanks for the tip.
I'm noob w battery. Do you mean just charge it full, pull it out and put it back in and it lasts you that much? I'm skeptical....The most I could have so far is 12 hours and I have 3 bars (out of 10) left.

The main reason people are having drain on 4g from what i heard was the software for the radio was re-written at the LAST minute (the reason for the delay) because they had to change their 700 MHz frequency just a bit higher.. something like 5 or 10 Mhz due to interference with with communication towers at airports. this sucker keeps dropping 4g like its no ones business. the new baseband which will be pushed out in the first update for the phone (hopefully in next month) should correct it.
Thats funny because i was at the gp today and my battery died before i left at 1p. Took a couple of pictures and 1 video. Used gps for like 10 mins and that was it. Stayed in my pocket for the rest of the day.

I'm in a 4G area so I have the phone set to LTE mode only and I get great battery life.
I probably have the worst battery life ever... 70% before putting it away and not using it. 5 hours later, I check my battery and I'm at 10%!! I didn't even use it!

The battery life on the TB is just as good as it was on my rooted dinc with a custom kernal. I have no complaints with stock unrooted TB so far and I use the **** out of it.
I turned off 4g and am going 16 hours on 50% battery. Really, to sit in my pocket, do calls, text, and check email I don't need 4g. I too noticed the 4g radio switching on and off constantly. Hopefully the baseband update will fix this.

What do you mean, is there a special way to charge it now?

I think he may be referring to the "bump" charge. Where you charge the phone to full, unplug it, turn it off, charge it to full again, unplug, turn it on, and charge it to full again. Not sure if this is an HTC thing or just a general lithium ion battery thing. But it helps IMO.
I get about 12 hours of battery life with moderate use. I little web surfing, lots of texting, light app usage. My phone is constantly switching from 4G to 3G when I'm indoors. Outside though I'm fine. I'm surprised about the different experiences people are having with battery life.
Since I can't get through a whole day without it dying I bought a second home charger on amazon. I'd like to get the extended battery, but it looks like it'd make this phone too big at that point. I wish there was some better battery tech coming out soon, since there hasn't been too much progression on that front.
Turn on the wifi radio. When you are home or anywhere you have access to wifi, the device will automatically turn the 4g radio off when wifi is up. That simple change has made a huge difference and I dont have to worry about turning the 4g radio on/off manually.
I've been seeing, under heavy use, at minimum 8 hours of use consistently since I've been through a few cycles, including bump charging the first few cycles. Also, a few things that greatly helped me:
Read somewhere that the stock blockbuster app, even if it has never been opened, has a service that updates the movie catalog in the background. Run the app, update it, and in settings turn off movie catalog updates. After doing this my battery didn't drain nearly as fast while in my pocket. I can't verify that this actually helps, but it did for me. I disabled the 4G radio since I live in a 3G area as well.
I also run Green Power as of this morning. My phone has been running over 12 hour with 3:30 of that being actual usage and I'm at 68% remaining. I have it set to 1 minute on and 10 off for data while it is locked in my pocket.
Beyond that, GPS is disabled unless I need it. So is WiFi. Brightness is at about 30%, with a widget to bump it to full when I'm outside in sunlight. I also noticed a big jump when I disabled HTC sense Facebook updates, and used stock Facebook instead. Every time I went to contacts it would download that contacts Facebook updates, which is pointless and uses data constantly under normal usage.
Of course your mileage may vary, but this all gets me through the day under normal usage, and over a half day under heavy usage.
I am currently at 8.5 hours with 79% left on my battery. Stock Battery. If I didn't have to work tomorrow, and be able to make phone calls and such I'd leave my phone unplugged all night to see how long it can go.

I'm assuming thats with Virus Rom as it says in your sig? If so, that makes me want to try it. I'm stock unrooted right now, haven't had time to invest in rooting the ADB original method yet, don't want to rush through it. When I do, I fully intend to try that rom out.

Informal battery test

There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...
10 minutes of on-line gaming (storm8 games) = 10% drain

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.
Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks
From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.

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!

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.

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.

Battery life up to 30 hrs?

So i've read forums about battery life exceeding 24 hrs...i've seen the topic's about using wifi when available, turning off data, using only 2G, and I've done all that...buuuuut im not getting no where near that life span.
im still getting maybe 5-6 hrs.. and thats just really texting, facebook/twitter (occasionally) and xda app 2-3 times a day.
What gives? Am i just using the phone too much? Is that 24 life span standby only? Someone please explain...Thanks

Are you using a stock rom, custom rom, stock kernel, custom kernel? Info man, info! I've seem some testers for Morfic's up and coming kernel for cm7 stating their 24+ hrs. I'm using latest cm7 nightlies, faux's kernel and I get 15 hrs light use with full signal. That being said, I think there is already a thread about this; try searching for it, there might be more info. Or I might be wrong.
Using CM7 with stock kernel I get around 24 hours. The best thing you can possibly do is rig up something that will underclock your phone to minimum when the screen is off. PimpMyCPU and SetCPU can both do this, which app you use depends on which kernel you run.
On the stock rom with all of the bloat and without adjusting sync options for all of your apps and accounts, your battery life will be horrible. A lot of bloat auto runs in the background. After removing the bloat, I would get a consistent 12 hours with two email accounts syncing, Facebook, twitter, mutplie pulse feeds, weather etc..
When I turned off data and syncing, removed the sim and just used the phone as a gaming and web/xda browsing device, I got 3 full days of battery life. Yes, 72 hours. This is on cm7, stock kernel. Wifi stayed on for the most part, (set to turn off when the screen turns off) and I spent a couple of hours total gaming on it.
Data KILLS the battery life on this phone. You'll gain a significant amount of battery life by managing the amount of time it runs when you're not using the phone.

To the OP, you're like most of us and use the phone for entertainment, with constant use the stock battery will be down to about 50%, with watching videos, gaming and browsing the web within 3 hours.
I seriously doubt anyone is getting 24 hours on stock battery even using custom ROMs. It could be that they don't even use the phone, and they have juice defender while it's on sleep, to get such numbers, or they' re exaggerating and posting fake info to push a certain ROM.
As far as 15 hours, that seems to be what the stock battery is able to achieve before it dies. So, no the cm7 ROM is not achieving anything that stock ROM isn't as far as battery life.
I have the mugen 4500mah extended battery, and since having it for about a month now, I can say with heavy usage, i.e. watching movies, listening to radio, playing videogames nonstop constantly, hour after hour, the battery will last you from morning until next day early morning. On very light usage just using it as a phone with very light browsing, out will last you about 2 days. I thought out would last me a week but I seriously don't know what is dreading the battery when on standby, and this is ther problem with the phone.
Maybe it's the apps that are accessing data when not in use and the radio. Right now I'm trying to see if droidwall will help to extend battery life, by not allowing programs to access the network.
I'm currently experimenting with a Tasker setting where the phone drops data to 2g only when the screen is off. I can't turn off data altogether because I use Google Voice for all my texting (save $10/month), otherwise you could save a huge amount of battery by disabling data completely. So far I'm not noticing any change with just 2g.
Well everything i run is stock....i think...im new to all the custom ROMs and stuff...all i did with my phone was use NVflash, clockwork mod and load cm7 nightly (version 75 currently) ....i lovr it and glad i came across this site with TONS of info...i learn new stuff daily by just reading posts on the forum but idk how to use custom kernels or load them or any of that...i dont want to start talking about that here since im sure theres a post about it in the forum ....but i just didnt know if that battery life span is capable of being reached or it was a load of crap....

terrible battery life

ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down. No overclocking.
Kernel: 2.6.32.9 [email protected] #30
I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.
If you are in a spotty area, that can happen. Searching for signal and 4G/3G switching can drain the battery very fast. I would try putting the phone in cdma mode while you are at work or any other spotty area.
Turn off wifi and gps if you are not currently using them, wifi scans for networks regularly and you may have apps/widgets that are using the gps/ network location services while you are idle
also, my battery stats say that display is using up 45% (as of now) of my battery life with 23 mins of usage time. I have the wifi turned on for my convenience, but it doesn't scan for networks as i've turned that function off. I will try the cdma switch, but I have also tried that before and I don't think it makes too much of a difference.

The battery usage metrics aren't useful until you've been up for several hours. And having the screen using a high percentage is ideal -- it means that the rest of the system is throttling like it is supposed to.
How long have you been on GummyCharged? A few weeks into having that on my phone happily, battery life took a nose dive similar to what you are experiencing. I flashed back to stock and battery life is much better. Waiting for official GB before trying another ROM.

i see your point but im now at 5 hours uptime with 23% battery left.. light/medium usage. display still says 46% battery use with 25 mins of usage time. that seems like incredibly too much battery drainage.
also, when i put the phone into cdma mode do i select the home or automatic option, and what is the difference?

i flashed GC onto my phone in mid september. since then i've tried calibrating the battery several times. a totally futile exercise it seems. What setup are you running now? 2.2.1 with EE4 modem? Rooted?
The only thing that has solved my battery problems is juice defender. Sitting idle for eight plus hours at night I only drop about 3-5%. Of choose it still drains just as quickly while using the phone but it will help if you're in a spotty area because data is turned off if your screen is off.

I've never had good luck using a modem from one rom with a DIFFERENT rom/kernel. Always docreased my performance.
I find it odd that Battery is the only issue you are having.

I have similar issues. After rooting and flashing Humble on my phone, my battery life sucked, much much worse than stock.
I then put the standard 2.3.6 on it and it still sucks. Full 4G all day, barely use it.
It's sat on my desk at work all day today. Sent a few texts. I've installed betterybatterystats and nothing is taking up a large portion of partial wakelocks.
Really don't understand how people are getting such good numbers...
I find that by far and away the best way to increase battery life is to lock my phone in 3G unless I am downloading something & want the 4G speed.
I have a home screen widget that turns 4G on/off & only turn on 4G occasionally. I do not leave WiFi on although I leave GPS on at all times & find that uses almost no battery life whatever.

I thought my battery was bad then i looked at that graph. I don't even get it... The screen is mostly off and the signal is green most of the time.
It may be some rogue app on your phone. Backup your apps and do a factory reset. If your battery life significantly improves, restore your apps one by one and find the culprit.

Just stock EE4, unrooted, will do OTA as soon as I get the notification. Battery life is not that good, I can get 14 or so hours of use leaving it on 3G most of the time, but on Gummy I would get 50+% drain just having it sit overnight. Now leaving it sit overnight doesn't kill it.

Hotboots are there but only like one every 2 days. The status bar glitch is still there. I use gc because i can't stand the default lock screen.

If you pull out the charger at 100%, it force closes (rest of phone is usable) and comes back inn a few seconds.

you prob shouldnt be using that ROM..its kinda outdated...just flash the new ALL IN ONE ODIN of EP4D...my battery life is pretty sick...i left it unplugged all night and saw a tiny drop..my phone was connected via wifi tho..if my phone is in 4g the battery loses pretty quickly or if my screen is on ultra bright..
I'm running the stock, rooted, manually-debloated EP4P and I've been getting downright stellar battery life.
My kids watched an hour of Netflix this morning while getting ready, and now (almost 10 hours later), I'm still at 63%.
But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

is there an odin file for what you have or did you do the manually debloating after rooting?
