[Q] evo battery - EVO 4G General

so ij am wondering about battery life it really sucks balls i can't get this phone to last over 4 hours on a full charge i have a advanced taskiller juice defender is there something i can do to resolve this or will the battery ext really help this out tremendously another question swype i can't get it to work on my evo anyone have a idea why i don't really see the imput method to enter swype either.

Get rid of ATK and Juice Defender. They do more bad than good.
Is your phone rooted? and have you "conditioned" you battery yet? What do you do with your phone? These things could help us help you.
I am rooted with MikG ROM and I conditioned my battery. I get at least 15 hours out of mine and that is with streaming Pandora for at least 6 of those hours.
As for your Swype issue, make sure it is installed. It comes standard with Sense and any of the Evo updates.
EDIT: I was looking for the post I followed to condition my battery.

This helped my battery life a great deal.

Four hours?! You've gotta have all your radios on and be doing a lot of something for it to go down that fast. Root that action, get a good kernel and do some CPU scaling and maybe some undervolting.

I agree with CDKJudoka, get rid of task killer. Although, Juice Defender doesn't seem to be a battery drain. If you're not using Bluetooth turn off, big drain. Also you must check any email accounts you may have set up. Goto settings and check how frequent they are sync'ing. Same goes for FaceBook and other similar apps. 4G is a battery drain, especially if signal is weak or toggling between 3G. If you're not rooted, you may want to consider it. After rooting mine, battery life has drastically improved (depending on ROM). I'm also running MikG ROM, which works great for me. I used to have the Seidio 3500 battery to last the day. Now the stock one does the same.
As far as Swype, goto menu/settings/language & keyboard, select Swype and tap Swype settings, then choose tutorial. At this point it should let you choose input method. Hope this helps.

Well here's how good the Evo 4G battery life can be:
I recently upgraded to the Evo 3D and left my Evo 4G laying on my bedside table using it to check email and as a backup alarm clock. GRANTED it doesn't have service and everything is underclocked and my battery is an extended battery.. BUT I picked it up about an hour ago. 7 days 13 hours on battery with no charging... and still 8 percent left on my battery which will probably make it until mid-day tomorrow. Under normal use I was getting 3-4 days on a charge.
CM7 and Tiamat kernel.

If you arent rooted here is what you can do:
1) turn off wifi, data, gps, bluetooth when not in use. (I also turn off the wireless networks location service)
2) turn off haptic feedback and vibrations on keyboard.
3) turn off automatic syncing
--Increase the time email, facebook, gmail, twitter, etc. refreshes data. Instead of every 30minutes, make it 2hrs. I turn auto refresh off because I update every time I go into the app anyways.
4) If youre running gingerbread- turn off google backup (under backup data)
5) turn off any animations in the system.
Now if your evo is rooted here is what you can do:
1) download setcpu and underclock the cpu and set up profiles for when the screen turns off that the cpu downclocks low.
2) user vipermod's undervolting script to make the cpu run at lower voltages.
3) use CM7 or MIUI for your custom ROM. (Someone please suggest a sense/gingerbread rom that has good battery life)- A good kernal with one of these is Thiamat or Saveged-zen

@ CDKJudoka i am going to give it a shot hope this works as for the rest of you guys thanks for the help the awnser is yes i am rooted and i am running android 2.3.4 kernal version i am usiong is 2.6.37.6 _cynogenmod 01504 rom is gingerbread-evo-deck 1.2 buld is grj22 i noticed my battery is a little better with this rom not a whole lot better maybe it is because i am running a stock rom everything is off as far a underclocking i will do it if i have to however i believe i should not have to underclock it for it to get through the day just a opinioni wonder if i can take my phone to sprint and have them look at phone and see if there is some battery issues is there a way that they can do that even though i am rooted. i am not sure if i can reverse it cause doing all this on linux can be a bit of a issue? thanks everyone for the quick response i will try battery conditioning tonight

Not a problem dude. I don't have my phone underclocked at all and I am using the newest stock ROM. Over the past three days I have charged my phone overnight once, and I am still going strong. You will notice the battery drop very quickly after removing it from the charger. Mine drops from 100% to 89% in about 30 mins, but it holds at 89% for a good 2 hours before it drops again. That is while streaming Pandora and downloading a 260mb ROM over WiFi.
I will just let you know now that if you bring a rooted phone into Sprint for service because of battery issues, they may try to blame the root and the custom ROM for it. Try to do the steps that are outlined by the other posters and the HTC double battery thread. It may just save you a trip to the Repair Centre.

I took my phone into a sprint store for them to check the battery. They ran a test on a machine. The guy said it passed but said "I noticed youre running a custom ROM, so it may be that."
But I've realized I get bad signal where I work during the day and somtimes roam while in the building. On weekends im able to go easily 10hrs and only be at 75% (stock battery).
You may also want to check to see if you have any rogue apps running in the background that eat up cpu usage or data

Batteries and Battery Life

I've had my Hero since October. I've been reading these forums ever since I bought it. I keep reading about people switching from one rom to another, discussing battery life changes. Some people are stating they only have to charge their battery every two days, or get 16+ hours of heavy use on a charge. I'm on my 3rd rom, having tried Modaco, Fresh 1.0, and Fresh 1.1. I am now runnning Fresh 1.1 + Gumbo + SetCPU.
I work for Sprint. Advanced Tech Support. I work 13 hour days. I get to work, I turn off the mobile internet connection on my phone. I disable background data. In my SetCPU, I set it to powersave mode Min 245 Max 485. (Those might not be the exact numbers, at work can't check, but you get the idea.) After 13 1/2 hours, I go out and my battery is giving me the >15% remaining warning. I've maybe missed two calls and recieved 8 txts. On my off days, I wake up, take the phone off charge, and do a moderate amount of txting. I play a little music while im playing Xbox, maybe open the browser to check a game FAQ or walkthrough. Within about 3 hours of waking up I'm below 50%. If I'm planning on going to the bar to shoot pool I have to make sure my battery is fully charged, or if anyone is trying to get in touch with my I won't know cause I'm at the bar for 5+ hours txting and talking, and my phone will have died if not 100% charged. So...
I read that running Fresh 1.1+ Gumbo + SetCPU would greatly increase my battery life. Tried it. haven't noticed a change. I don't use task killers, I don't run apps, I think I've downloaded 9 apps from the market in 5 months. I use Shortcovers (Ebook reader). Dolphin browser, Handcent sms. Thats about it.
Is there a viable solution here? Does anyone have any troubleshooting steps to recommend, apps that might help, do a complete wipe and re-install Fresh and Gumbo? Change settings in CPU? I've been reading about Mugen and other batteries, any recommendations on which one would be best to try out? I love my phone, and I don't do anything to it without reading up on these forums first, just looking for any advice to not have to stay tethered to an AC outlet all day. Thanks.
fresh 1.1 + the less aggressive gumbo kernel will help alot. you don't need setcpu at all. i also recommend looking into a bigger extended battery, one that doesn't require the use of another back cover.

It really sounds like you have a background task that is running and not letting your phone sleep. I turn off mobile internet at night (so I don't get bugged with Tweets and other alerts) and my battery drops 3-4% overnight (7-8 hours while sleeping). What is your awake time?
On a full charge, I can go all day (7am - 10pm) and still have more than 30% left. I have 2 email accounts, each set to sync every 30 minutes, a twitter app set to sync every 15 minutes, and I don't use weather or location services. I think a lot of people experience poor battery life due to signal quality. I get really good signals at home and a fairly decent signal at work as long as I say out of the lower (basement) floors.

Here's my experience with my HTC Hero from H3G (Three) UK:
Had the phone for about 2 weeks now, battery lasts me easily 1 day with quite heavy use (30-60 min GPS, 2-3 hours browsing, installing programs, 30 min music, some texting and talking. I know that for some of you guys out there this might be 'light' usage, but I believe for all of this, battery life is quite good, better than my friends' Iphones. With moderate use i get through 2 days of usage. I am just experimenting with turning off Mobile Internet, have had the phone running for 60 hrs + and my battery is at 65%, I've been turning wifi on for a few minutes a couple of times and have been talking and moderate texting during this time. I intend to leave Mobile internet off until the battery runs out of power to see how much time I get out of it. I never turn the phone off at night. I am amazed what a big difference turning off Mobile Internet does.
The OP clearly states that he downloads / runs minimal apps, and asking a Sprint advanced tech if his phone is sleeping, while a nice gesture, isn't terribly practical. I hope.
I think that there are certain phones that don't scale with GCK or a change in the CPU governor very well. I have bounced around to every ROM available, flashed and reflashed, cleared boot and dalvik caches and played with about every governor / frequency setting imaginable. With all that, all I can conclude is that my personal phone does significantly worse when the governor isn't MSM7K and drains downright terrible under GCK's stripped governors on anything other than MSM7K. Even Powersave (which OP referenced) drains my phone significantly faster than MSM7K.
I'd recommend you keep your current GCK install and adjust SetCPU to MSM7K to min 245 max 480. Then enable Profiles > Sleep > min 160 max 245. For a bit more performance when your phone is awake slide your normal max to 528; add significant performance by sliding normal min to 480. See if that helps any.

Could just be the different experiences folks receive with the Hero but when I used SetCPU to create profiles, I saw much higher battery drain. Once again, may have just been my experience but battery runs much better without profiles on my device.
Thanks for the response. And yes, my phone does sleep. I checked Spare Parts, and my most used app is Lightning Bug (use it when I sleep at night. I live in the hood and it covers up the radios and dogs barking.) After that it's Shortcovers (my ebook reader.) and then Handcent. So no abnormal program activity. Lightning bug only runs while I sleep, shortcovers just when Im reading. So nothing keeping my phone awake or anything. I do have one of the first Heros, I pre-ordered and recieved it like October 10th, so it's not Google branded, if that makes a difference. I'm considering just getting another one, but after 5 months of flashing and moifying and tweaking I'm kinda attactched to my phone. I'd feel like I was trading in my wife. So I guess I'll just go for an after market battery. Any more advice would be great. Thanks again.

Personally I'm on Modaco 2.2. Pulled mocaco.sh and changed the governor from "performance" to "msm7k" and pushed it back to the phone. No compcache, but I did include the internal task killer call in compcache.sh. Read thru either the Modaco 2.2 thread or GCK if you need help.
I'm having the same results as you. I have a non-"with google" Hero200, and my battery life absolutely sucks.
Today, took it off the charger at about 10:30, now at 3:30 it was down to 20% battery.
this was leaving mobile data on and a few text messages.
How exactly do you choose how often you want email to sync? I tried finding that in the settings menu of the Gmail app, but there's nothing there about that, just signatures and such.
I am running gumbo 1.5c bare, so it's quick (no sense UI) but battery is just as bad as with sense.
I'm not running setCPU or anything, just gbhil's kernel (i think?)
I'm about ready to spring for an 1800 mAh battery

Hate to say it, but I'm glad im nota lone on this one. Misery loves company.
I'm gettin tired of reading about people claiming they get 2 days of moderate use out a hero without charging, with a stock battery. "Oh, with this new rom I just tried, after 12 hours I was below 50%, this is unacceptable, I can normally go 2 days without charging." WTF? Did they just build a choice few heros with super batteries? Just wondering.

Lol, sorry man (I'm guessing you read my post at one point, 12 hours to 50%, it really did annoy me lol). I CAN get 2 days using Fresh 1.1, gumbo kernel, and SetCPU. Granted, I don't use my phone nearly as much as a lot of the people on here, but I also sit in areas with little to no service for most of my time, which can have a drastic effect on battery life.

OUCH. I unplugged mine at 9am, it's now nearly 4, and I'm only down to 80%. Had WiFi on all morning, and mobile on from noon on. Sent a dozen texts, and read a half dozen emails (syncs every 15 min). Mobile data SHOULD sleep when your phone goes to sleep, and I think it'll turn on when your accounts/email sync. Same thing with WiFi.
I'm amazed at the massive variation in battery life people have. I wonder if there were a few different manufacturers of batteries, and that's causing the problem.
But I cant even bring my phone into the building so it sits in my glovebox with all data services off and no apps running for 13 hours and its at ten percent when I get off work. I just don't get it. I think I'm gonna wipe, reflash Fresh 1.1, reflash Gumbo, and start over.

Wow, it sounds more like something might be wrong with your battery.
I could turn everything off on mine, and leave it sit in an area with decent service, and probably get over 2 days out of it...so that just seems odd. Are you running SetCPU? That'll help. Set it at either 160 or 245 min, and 528 max. "On Demand" seems to be working the best for me. It'll basically drop your processor speed when the phone's asleep, and bring it back up when you need it.

+1 on this. While I understand you're a Sprint tech, it's still good to check the awake time, as it's a good indicator that something's awry. You said you run minimal apps, do you run any weather apps at all? Had some bad luck with those. Also, do you roam? I know setting it to Sprint Only helped me at home, and this is what you suggest to ppl everyday, so I'm not telling you anything, but some of the things we KNOW to be absolutely true can be wrong under our noses sometimes because we're so sure. Double check everything again.
I know it's painful to think of this as a viable solution, but there absolutely IS a way to determine if it's apps or not. I've had great luck with Fresh 1.1 AND Gumbo 1.5b. SetCPU and Gumbo Kernel made it even better.
Try this: Install either Gumbo or Fresh 1.1, the Gumbo Kernel, and setCPU (that one is optional for you I suppose, but I'd recommend it)
Don't install a single app or widget for the first day. Not a single one. Leave it for 24 hours, and see the battery life. (exceptions for apps that don't run in the background or connect for data or updates)
Then install them one by one until you find your culprit. This is how I found the weather widget was sucking the life out of my hero.
I too, have a non "with google" hero 200, and I have GREAT battery life, and even had great battery life on Fresh 1.1 when I had near 80 apps installed.
I'd bet money it's something in the background. I can speak a lot for Fresh 1.1 as I've used it the most. Great ROM, great battery life.
Btw, I also have two email accounts, one Exchange, one Gmail, BOTH set to "as items arrive" and I still can go from morning to bed on a charge with no probs.
**EDIT**
To echo Tatonka_hero, I also recommend doing the ondemand 528/245 as it worked really well for me. I got even better battery life when going that route than before, although I was never complaining about battery life in the first place.
my opinion.. it has to be something due to the signal strength.
I wonder if there is a way.. to check and monitor how often the phone looses tower contact? Then it has to try to find the next tower available, then has to bounce back to the closer one when it pops up? Is it constantly, jumping from one week signal to the next?
Which would keep the radio up and running... while the phone itself looks asleep.
Just me guessing.. with no Knowledge to base this off of.
I don't use any weather apps. A list of every app I have that didnt come with the phone:
Handcent
Shortcovers
Lightning Bug
Gensoid
GBCoid
Spare Parts
Terminal
ES File Explorer
SetCPU
I know you guys are really stuck on the idea that I'm running some intresting app, but I'm sorry to dissapoint. I wiped the phone, flashed Modaco, wiped, flashed Fresh 1.0, wiped, flashed Fresh 1.1, wiped, flashed gumbo. And then I re-downloaded the apps above. I work 7 days a week, I like to read Ebooks before I go to bed, I use lightning bug when I sleep, and if I'm riding with someone I play my emulators. Thats the story of my phone use. Also listen to music if I take a day off and im playing xbox. Theres nothing running in the background. I always have at lest 3-4 bars of signal strength. I turn off mobile network (data) when not using it. I keep my GPS off. I check Spare Parts, and everything in there is pretty much correct. My phones awake time is about 20%, if that. haven't checked in a couple days. So, tonight I'm gonna wipe, re-install Fresh 1.1, re-install Gumbo, and see if that helps at all. Is there any kind of consensus on the best settings for setCPU to save my battery?

Thanks for the detailed reply...it helps us get a better picture of your habits.
That being said, use the ondemand 528/245 and you should be just fine. Make sure to set it to save those settings on reboot too, because setCPU used to (not sure if it still does) set itself to performance mode on reboot otherwise which would definitely drain your battery.
alright this is probably a stupid question but how do i check awake time with spare parts? is it under battery history? then is it partial wake usage option?
And is Locale.apk known to be a battery hog...I feel like it might be...ouch.

Horrible battery life on EVO after rooting

Hi all,
I folowed both part 1 and part 2 to root and unlock nand on my evo. I loaded the freshevo 0.3 ROM and applied the 4g fix from flipz. Now, my Evo lasts about 5 hours in standby before the battery is dead.
My Evo used to last most of the day before I rooted it. Has anyone experienced similar issues?
Thanks,
Rayden1000
Did you flash the new radio?
Did you leave 4g on?
Gps?
Bluetooth?
What are your sync settings for social network, weather, news?
We need more info than my battery sucks.
Flashed the new radio.
4G is on - as before rooting.
Bluetooth, WiFi is off.
GPS is on - as before rooting.
Syncing is at 4 hour intervals.
Exchange is "as items arrive" - as before rooting.
I know that everyone complains about the battery on the EVO, but my phone is dead after just a few hours of non-usage.
My Up time and Awake time are almost the same, so I think something is preventing the phone from sleeping. An hour ago I went to some setting that listed which app is using what percentage of the battery. I can't remember where I went to check that now, and it wasn't the stock battery settings app. It said that HTC Sense is using 97%.
Thanks,
Rayden1000
Try this
http://forum.xda-developers.com/showthread.php?t=700601&highlight=100%+time
Also you might have a bug with 4g where it is constantly connecting or trying to connect. See if the fix above works. If not try damagecontrols rom and see if its any better. Or you can try disabling 4g and see if there us a huge huge huge gain.
I do know that right now some of the custom roms have had 4g issues. I'm not in a 4g area so its hard for me to test.
Thanks Aridon,
I already checked out that thread, my phone is set to CDMA auto.
And yes, I did have the 4g bug when I unlocked NAND through method 2. I found the fix that flipz posted and that has fixed the 4g issue. I also flashed the freshevo 0.3 rom that has the 4g fix built in.
I will try flashing the 4g fix again right now, but does anyone have any other suggestions? It seems that battery performance decrease is a common issue after flashing custom ROM's.
Rayden1000
You should consider doing the steps in that thread regardless if what it shows. The hero had a display bug in that regard for some and perhaps so do some evo. Seems odd but there are differences because when you start playing with kernels it will boot on 002 devices but not others so there are differences.
I'd do it, set it and reboot. Don't go back in to see if it changed just start a new battery test And check for improvement
turn off 4g, my evo has everything yours does! but end of the day i get home and still have over 50% battery life left! if you have 4g on it drains the crap out of battery. only turn it on when your going to use it!

I do understand that 4g decreases the battery life significantly. What I am trying to say in this thread is that after I rooted and unlocked nand on my evo, the battery life is MUCH MUCH worse then before rooting. My phone's battery now goes from 100 to 0 in about 4 hours - while I am not using it at all.
I am just trying to figure out what process is running all the time and prevents the phone from going to sleep.

Dude download Overclock Widget. Do a google search for: Overclock Widget HTC Evo.
I swear on everything I love that after I installed it and went through the settings my battery lasted 11 hours today. I still had 23 percent left and I streamed some videos on the web, listened to music, played around all day with my phone. It really works and some people claim 30 plus hours of battery life.
It works and I will post a screenie tomorrow of the proof.
Whatever it was, installing Damagecontrol 3.1.2 ROM "appears" to have fixed the issue. My phone has been in standby for about an hour and I have 93% battery left. I will leave it alone for the night and will post the battery status tomorrow morning.
Thanks to everyone for trying to help.

Whatever it was, installing Damagecontrol 3.1.2 ROM "appears" to have fixed the issue. My phone has been in standby for about an hour and I have 93% battery left. I will leave it alone for the night and will post the battery status tomorrow morning.
Thanks to everyone for trying to help.

I may have spoken prematurelly, this morning the battery is dead again. I have tried numerous ROMs with the same result. I also tried old radio ROM ans new radio ROM.
Has anyone been successful at following both part 1 and 2 of rooting and maintaining decent battery performance?

Not to sound noobish, but did you already disable GTalk auto sign in and then sign out?

Did you NOT just read my above post. I clearly gave you a fix SMH. Here's proof of what I'm talking about:
I took a screenshot with the ShootMe app. I'm currently running Fresh's latest ROM. The screenshot indicates that I had it off the charger for over 14 hours. I used my phone today to send a lot of text, skyfire, streaming flash websites, etc. By the way I have about 40-50% battery left.
Installed overclock widget, set it to run at around 247 mhz at all times - same result. Evo battery is dead after about 4-5 hours. Does anyone have the original ROM for the Evo? I tried running the RUUxxxxx.exe files, but they all fail - probably due to me rooting and unlocking nand, therefore modifying the file system.
Rayden1000
I've been running Fresh 0.3 for a few days now and haven't seen a problem. Have you tried getting a task manager and making sure there isn't a program running in the background causing all this? Also, is your phone hot... if it is, it means you go something taking up some major cpu time.
I had a similar issue with my Hero, the cause was it was trying to sync the calendar over and over non-stop. You should look at your account syncing also, there could be a problem there.
Sounds as if you have something running in the background that is killing your battery. When you are flashing your roms, are you doing a wipe first or just flashing over whatever you had before?
I don't see how you're running overclock widget and getting bad battery life. Download Advanced Task Killer and kill those tasks.
I also had an issue like that after installing some ROM (I forget now what one, since it was a while ago) and my battery died over night while I was sleeping. I don't really know how (if I did) fix it, but I wiped everything, factory/data/dalvik/battery stats (whatever that is) all those options, then installed a new ROM and it seemed to work fine.
As for the overclock widget, I downloaded that and tried to use it, but it didn't seem like it worked. It just didn't seem to stick and I didn't really see any increase (maybe even a decrease) in battery life. Probably the best thing that you could do is get a task killer and see if there is something running that needs to be killed. The awake time shouldn't be anywhere near the uptime

Answers on battery life.

I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.
A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.
yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.
You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.
You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.
I know how to kill the processes for the DRM and downloader but how do I remove them?
OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......
I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?
That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.
There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).
Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..

My experience with GREAT Galaxy S battery life!

Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.
I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use
Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.
I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.
Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Eclair for both. No Froyo.
what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly
Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.
Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.
Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.
Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

Terrible atrix battery

I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated
Edit : phone idle consumed 40% :O
I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot
Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...
New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...
Sent from my Samsung Seine
I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.
Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.
The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same
When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.
How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.
i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.
I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.
When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)
After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.
