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.

It's just under Settings > About Phone > Status then all the way down
Today I decided to do a real world test of the Evo's battery life. I used my phone the way I would normally use it on an other day. As for the phone itself, I am running the rom from the OTA update. The only changes that have been made is that I am using unrevoked root method so that I can use the Overclock Widget (marketplace) to turn the processor freq down to 245000 when the screen is off. I also use Advanced Task Killer to turn off apps that I am not using. I had bluetooth and gps turned on throughout the entirety of this test, wifi was on for about 3.5 hours. During this test I played a game for a short period of time, did some light web browsing, and had several phone conversations that totalled a little more than 2 hours. With doing all this, my battery lasted for a little more than 11 hours. That being said, under normal use the Evo should definitely last you throughout a full day.
Thanks for the info. I got my Evo yesterday and haven't been able to put it to through extreme testing yet
No problem. just kind of got tired of hearing how poor the battery life was. Even before using the overclock widget I was still getting decent battery life, but the overclock widget just put it over the top. To add to that, I don't normally talk for 2 hrs. on my phone during a normal day, so really a lot of that 29% battery drain from phone use wouldn't be there. The only thing I didn't use today was 4g (which I don't normally use unless I'm on the phone and need to use data).
Not sure what this proves or "dispells". When people (myself included until making some friendstream changes) are getting 6 hours out of a charge with light use, that is a real problem. You must not have friendstream syncing...if you did and did everything you just wrote about, your phone would be dead in 3 hours tops. Thanks for the info., but once again, people are havnig real issues with the battery...it's not made up.

If you are experiencing poor battery life then it is most likely attributed to not managing your apps properly (friendstream included). For example, without advanced task killer you will get a drastically different amount of battery life than if you have it. Then add to that, the way you configure advanced task killer can add a large amount of battery life compared to having advanced task killer without it being configured properly. Even with friendstream running you should still be able to get a decent amount of battery life (I am aware that it does use more juice), try having your facebook sync less often.

I totally agree I've been using my evo and been fine, I only really have it connected to power when I have it tethering. Besides that it lasts me not all day but while I'm at work (which is the most important part) I get a good 9-10 hours out of it before I really need to charge. It should also be noted that I use locale to switch BT and wifi off when I'm not in an area to take advantage of them.
I think some people have bad batterys/evo's, it's not just a matter of running the right programs or killing tasks

While that is possible I think the majority of the problem rests with the user's mismanagement of apps. I have seen way to many posts from people declaring the battery life to be so horrible, only to make a few changes and then turn around and say how much better it got. If that person had a bad battery then the battery would still have been bad, it wouldn't just start being good. That said, it is very possible that there are people with bad batteries. I just think that most of the people have good batteries and bad phone management.
I did pretty much the same thing. I have the O/C widget to set the frequency to 245000 when the screen is off and also have Advance Task Manager configured to close apps I'm not using. Helps out a lot and I usually get around 12~14 hours on a charge.

While I completely understand what you are saying, I can't really agree that b/c someone is not getting a full day out of their phone it is b/c of poor app management. While deleting facebook for sense, then reinstalling with only contacts synced fixed everything for me, the fact that you have to go through the phone with a fine tooth comb to get it to run more than 6 hours at a time is pretty silly. While doing that stuff is fine for me and most on this forum, it will undoubtedly turn a lot of non-techie people off from this phone...especially with Sprint doing their new 30 day full refund policy.
It's all good though, just plugged my phone in after 19 hours...playing with it most of the day.
I use advanced task killer and turned off sync for apps I dont use. At 65% used pandora (in 4g for about an hour), browsed several sites, made phone calls, text, emailed. All the normal stuff. Took my phone off the charger 15 hours ago.
Prior to using advanced task killer I would be to about 18% right now. So for those saying that task managers kill more battery power my phone seems to do the exact opposite.

Task killers really only help if you have an app that would normally be giving you higher than usual wake time (the calendar comes to mind). At the start of every boot I always make sure to kill everything so only essential apps and those I use are running. I don't use any kind of auto kill.

Sent from my HTC EVO 4G using Tapatalk Pro.
It is no longer recommended that a task killer be used. It may result in poor phone performance.
After i rooted with Toasts method, installed OMJ's rom removing all of the sprintware and added the OverClockWidget to tweak the processor, i was able to go a full 32 hours without charging. i had gps and bluetooth on the whole time and wifi on for several hours. i made calls, sent texts, took pictures, basically normal usage.
Just to add to all this. Bad battery isnt just a HTC Evo problem. Go read the forums of almost every android phone released and they all report the same things (in the beginning). Someone that has had a android phone in the past probably hasnt said much about battery. There are so many things you can do to increase battery.
1. manage your apps. Exit them instead of leaving them running (press back button until the app closes, or some apps you can Menu> exit) Pressing home doesnt close the app, it only takes you to the homescreen. Also change the sync times of all your apps/widgets. If you dont use gmail or google calendar, then uncheck the "sync" in Menu>accounts & sync> google. One last thing use a task manager (not recommended by some devs) I use it to end tasks of apps that use data, or ones that i use maybe once a day or once a week, i dont need them cached for quick returning, so i end the task all together. I ignore apps so they dont end that i use very frequently or ones that dont use data or run in the background.
2. Calibrate your battery once like so.. Charge your phone to 100% and then use your phone like normal until its so dead it shuts off by itself. Dont plug it into the computer or wall charger in that time. Then once it shuts off, plug the phone into a wall charger and charge it till its 100% again. After that, plug and play as much as you want.
3. Buy a car charger, usb cord for the comp, and maybe another wall charger. Buy an extra battery or extended battery. Doing the above and adding these to them, youll have a huge increase in battery.
I have an htc hero and i can get well over 12 hours of use by just watching what syncs and what uses data. And i use my phone alot, and wake it up a ton to check for notifications.
I use a friends Evo so im not new to the device and I understand its a different phone.
Stock htc phones come with a lot of stuff preinstalled and widgets. When signing into them with your accounts the sync times are usually pretty high, some like every 15mins. Watch what you are doing with the phone and youll have normal battery life.
i avg 18 -19 hours per charge so im very happy
aaaaah ok now I know who is the idiot Dylan here. Thanks. What a dumbass know-it-all.
I think some people are getting poor battery life because intermittent signal. I know this was the case for me. When I go to a friends house that I barely have signal, the phone constantly tries to find signal or goes into roaming. It would drain the battery fast. When I was in good signal area it seemed to last quite a while. Just saying that it is more than just running apps that cause poor battery.
Also if you will not use the internet turn off the mobile network, put the widget in your screen. You can receive calls but the internet is off.

You make a very good point. Weak/no signal areas will drain your battery (as with any phone) very quickly due to the phone constantly scanning for signal. Not really much you can due about that other than turning your phone radio off or switching carriers lol. One thing I've read in the Dev forum that may help you is to change your prl to the Alltell/Verizon prl. Some people have reported that this works well in low signal areas.
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..
Just reviewed several posts and looks like there's not a lot of clarification on extending battery life on the Epic 4G.
Based on what i've read here, its possible to extend battery life with the following ?
GB update (sprint released rom or modded roms)?
Screen Dims, Auto syncing disabling, etc?
PRL update (not searching for towers)?
Data disablement?
I hope the GB and mod updates are the real answer.
The fact that anyone suggests to disable your data as a way to save the battery is mind boggling to me. Why would I have a smart phone if I had to disable data to save the battery (aside from maybe being on a plane or something where you HAVE to disable it anyway).
Look for randomking's thread in the Q/A section in epic development... the link is also in his signature, but he gives great advice on how to save battery properly.

I feel like I've tried everything but at this point I've resigned myself to poor battery life.
I have two Exchange accounts, gmail plus I use Yahoo and Live as well as a personal email account. Not to mention weather updates. I've got a 1amp charger in my car. A desktop cradle with a 1amp charger at my desk and another 1amp charger in a cradle on the table next to my favorite chair at home. At night I use the .5amp Samsung charger in a third cradle.
Basically, when I'm not using it its charging.
When I get up I automatically tap my belt case to make sure I don't walk off without it. I need it 31 and I need to know I get all email immediately and that I can be on a call for a couple of hours if I need to be.
But yeah, I wish I could just charge overnight and be able to depend on 24+ hours of battery life.

This is how I feel as well. I don't understand why you would want to have this phone if you are going to turn off all of its features. I don't undervolt. I am overclocked to 1400 and I have GPS on most of the time. I also use Bluetooth fairly regularly. I did spend $2 to get "Bloat Freezer" app to freeze the apps that run even when I am not using them. I also have a second battery. I can't obsess over the battery. I want performance and stability which I have. When changing ROMs, charge to full and wipe battery stats in recovery as well.

I'm looking to get another battery.
Right now I always have wifi on downloading stuff like 24/7 brightness all the way down(come on its not like you need it up anyway). I'm always overclocked to 1.2, and not undervolted and I don't use dark backgrounds, and have everything set to sync every 4-6 hours. I charge maybe twice a day never completely until night time.

If you live in a poor service area of town like I do, typically avg 3 bars all day, and often less...you are doomed.
I've tried all the tips, but the constant tower polling rakes my bettery over the coals. This is why I've adopted the multiple battery approach (with an external charger of course).

^^^ This. If not for rooting and Roam Control I'd have to almost not use my phone at work, and even then even Verizon's signal is low/spotty though to a much smaller degree in the building than Sprint's.
I do a number of things that are convenient for me.
I turn auto-syncing off. I don't need it always searching for updates in my life. I can spend the 3 seconds when I open the app.
I only put it on wi-fi/gps/4g when I need them. Sure, they can be on, but they use battery and it also takes seconds to turn them on.
I use auto-brightness. It works for me.
I do a lot of stuff:
- Leave GPS/wifi/4g/bluetooth turned off until I need to use them.
- Set screen brightness to the minimum, in both the OS and the browser.
- Use Titanium Backup's 'freeze' to disable bits of the OS I don't need, like 'DRM content'.
- Set up non-push email addresses to be forwarded to push email addresses (like gmail) automatically so that the phone itself does very little polling.
Doing all this, I can leave data on and easily have it last the day, every day, or turn data off and use it for a podcast player with BT headphones for a full eight hours.
Green power helps A LOT btw... its better than juice defender ultimate.

Freezing DRM saves a good portion for me. I also use Startup Cleaner to stop apps from automatically opening (not freezing) as soon as I startup my phone (swype, messaging, internet, etc). I'm not getting fantastic battery savings, but I've seen a difference doing this.
What is DRM?
http://developer.android.com/reference/android/drm/package-summary.html
It sounds like it would use some juice, but dunno that freezing may be most efficient for apps.
Dataswitch app by TomatoX. Its a widget that turns off 3G. I keep a Wifi on/off toggle on my homescreen as well. I connect often enough to get all my emails pushed through and what not so it doesn't feel like I'm crippling myself in the name of a little battery life. I went eight hours today and got home with 83% worth of battery. I prefer widgets over longpressing the power button personally.
These are a collection of the best suggestions I can make.
And no, turning data off is not one of them. Although disabling sync is.
DRM is a service for digitally verifying online store bought or rented audio/video. Itunes is a great example as the most annoying implementation of this concept. The problem is, that on our phones it runs constantly trying to verify files, whether you have any or not. If you don't think you need it, freeze it. Removing it completely has lead to problems. If you don't want to buy an app to do it, the terminal emulator commands are included in this thread.
PS: Currently I have not found one person that can top the best EC05 roms in battery life with a GB rom.
ok so i tried a couple of recommendations and i have some positive feedback!
I got green power and startup cleaner. After changing startup cleaner and using it to disable quite a few apps as well as drm and other non essentials it helped with my memory and apps running in the background.
I also tweaked green power settings to leave on the 3g and turned off the wifi on / off option (so i could do it instead of green power) and lt do its thing.
Excellent battery life. I left it on used it for a bit then let it sit and check a couple of emails, got a few pushed emails via gmail and did a few web searches.
i'm at 80% since 1pm. that's unbelievable yet that's the way it should be!
these apps / tweaks have helped. i do need push email and use push calendar from hotmail exchange.
i really wish the phone could do this on its own but i'll settle for this alternative using 2 apps at this time.
i hope gingerbread helps us all without the need for apps but i would probably still use them because of the substantial battery life gains.
Randomking is right.
All our efforts are minimal compared to what gb does....at least in cooked form
Rk..what custom rom do you recommed?

I think that's everybodys dream, to be ale to run this bad boy for 24 hrs straight. Unfrtunately were a long ways from that. Especialy from the way it sounds like you run your phone your going to becharging multiple times per day..that's just part of being a power user with a smartphone.
I gota agree though, fo the life of me i don't know why people disable data, or cripple thir phones ability just to eek out another hr of battery, this is a huge phone, with a big power hungry (beautiful) screen, you knew this when you picked it out. It can do pretty much any function that a laptop can. Use it like it was meant to be used, and dont fret so much over the battery.

Great News!
Battery life is now up considerably without the use of 3rd party apps.
I may consider using green power to get more extended battery life...but here's how i did it.
1. Update to EF02 Gingerbread OS (on a scale of 1 to 10 in terms of ease of upgrade...its a 2....1 being the most simple). It was as easy as download the app and let it upgrade your phone.
I'll post the video link here it was VERY Elementary folks.
2. Battery life in Gingerbread is great! Appears to have a better memory manager and much more smooth transition between screens, apps, etc.
Randomking was correct about battery life and adding all the apps we had to for Froyo just to get mediocre batter life.
Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.
