Same here, I got 2 batteries off of ebay so I use the hell out of my phone. Brightness is on max to show off that screen, stereo bluetooth and pandora,4g is always on, live wallpapers and browse internet and play games a lot (angry birds mostly) . Battery lasts me 7 to 8 hrs which is amazing based on how much I use it. If u are doing normal use and getting 8 hrs then something is wrong, ur maybe not in 4g and 4g is ona nd ur wasting batt looking for signal oor something else. Maybe u have a service running in the background. I removed media hub and drm bc I heard they run a lot, but I never did a proper b4 and after comparison so not sure if it actually does help. I'm using noobs andromeda rom and d18 update.

Id be SO happy if I could even get 6 hours off one charge.

I'm lucky to get more than 3hours these days from 100 to 15%. :\

I did have a lot of widgets, but I removed a majority of them. I NEVER have wifi, 4G, GPS or sync on. My brightness is always set to 0%.

I guess I just use the phone too much! I don't mind because I usually am able to get near a wall outlet to charge my phone in the middle of the day.

But I'm worried about tomorrow, where I'm leaving at 8am and not getting back till 6pm with NO ACCESS to any wall outlets. :( I'm pretty sure I'm not gonna make it. Lol.

I'm convinced that with regular use you are gonna get 8-10 hrs on a full charge. Hell by 8 hrs you are going need to start charging unless you want to wait until the phone dies so you can claim x amount of hours.

There is no point in turning off everything on your phone and barely using it to say it lasts 20 hrs. Get a charger for work, home and your car. It is what it is.

I wake up at 6am, charge by 2 pm when battery is around 30%.
[Epic 4G General] robl45:
the problem with this phone bottom line is that 3g is eating the battery life. I set wifi to always on and I'm always on wifi in the house. I can get 12-14 hours sitting in my house. whoopie doo. Thats not hte point of the phone, the point of the phone is to have mobile service, not wifi service. anyone that is getting 30 hours out of the phone is using wifi. So thats not even a fair comparison. I love the phone, but this is just stupid, I shouldn't have to carry a spare battery with me if I go to the daytona 500 from 9am to 9pm.
[Epic 4G General] akei1:
Yeah 3G does eat more battery life than wi-fi but that doesn't mean you can't have great battery life with 3G on all the time. I can get 1-2 days with 3G on and with light use, but that's in part because I get a good 3G signal.

I probably emphasized too much on wi-fi but the point I'm trying to make is try to avoid using a weak connection. Generally, I use wi-fi/3g/4G in my home but inside most buildings they'll most likely have weak 3G and 4G connections, so I use the wi-fi network inside the building.

You said you could get 12-14 hours with wi-fi and not touching the phone? I'm not trying to be rude but that seems really low. If mines idle on wi-fi in my home it lasts days. With 14 hours idling, that means the battery life drops 7% every hour. Idling on wi-fi I think it should only drop 1-3% per hour.

Mind if you go to settings -> applications -> running services and post what you have?
[Epic 4G General] tantran:
i get twenty four hours on average a full day so to speak wake up it says fully charged i take it off check twitter and facebook leave the house and dont touch it until i am at school bored in class lol and then it says 95 after a full day of class it usually says 66 thats after 9 hours i go home play with it download apps etc make several calls and i text alot all day by the way and then i go to work and it says 50 or about 48 usually i use it all night off and on til i get home at seven my wife kills the battery and puts it on the charger while i sleep usually about 9
[Epic 4G General] tantran:
btw my 3g is on i dont use wifi but drm is off and it still runs smoothly no force closes i dont sync email at all i just check it on the web as i feel like its worthless to have it draining battery seeing as i only get 7 or 8 a day my chief usage is definitely games,text and a few 20 minute phone calls
[Epic 4G General] Mr.Muscles:
I'm gonna sound hella noobish but how do I go about turning off this "drm" I keep reading thru this thread?

Sent from my f'n awesome Epic 4G
[Epic 4G General] akei1:
The easiest way to stop drm is go to settings -> applications -> running services

and tap on the drm process and stop it. You will need to do that each time you decide to reboot the phone because drm restarts when you do. It helps a lot with battery life.
[Epic 4G General] robl45:
ive been strictly on wifi today and its better, I could probably pull 16 hours out, but if I leave the house and switch to 3g, forget it, about 8-10 hours max. I can check the services, not now but I'll try to post that.
[Epic 4G General] churro7:
same thing here on 3g but i noticed that on the hero too
[Epic 4G General] shabbypenguin:
yall decided for yourself, i used my phone for voice calls mostly.. well you can see that :D
[Epic 4G General] ravizzle:
If u never plan on using media hub I would just permanently delete it and the drm services. U need to be rooted to do that though. There is a diff thread in the epic 4g forum that gives a great step by step guide on doing that try searching for it.

I rooted and installed the Epic Experience ROM. My battery life is like 20 hours minimum with heavy usage. I can keep 3G on when I'm gone, Wifi always on when I'm a home. Use navigation, etc. I turned on my phone at 6 this morning and its 11:12 p.m. now. I have about 45% battery left. I send at least 300 text messages a day and browse frequently, use twitter, beautiful widgets update set for an hour. This ROM has amazing battery life
[Epic 4G General] ravizzle:
I don't see how ur ROM is the reason for battery life, Is it underclocked/undervolted? I think probably a lot of factors such as being in a strong 3g signal area and the type of apps u use matters more. For example I use 4g when at home and 3g at school (no 4g there yet) and 3g is weak at my school/ inside classrooms so causes more batt usage. Also I use pandora a lot and also play games a lot. Just texting and internet browsing throughout the day as most ppl use it shouldn't use a lot of battery usage.

Same with me, I really don't see why you use Wi-Fi at all- call me cheap but if I'm paying 10 bucks extra a month for 4G (which, btw, isn't in NYC yet) then I feel like using my data and not my Wi-Fi.

i just got home, probably 10 hours of use and on 4% left..this was a few texts here n there and calls

One thing that does happen is that my gmail is on auto sync, I use my phone primarily for emails, google talk and texts- which is simply the nature of how I use my phone..

I guess what really goes to say is that my 3G coverage at home is really poor as well
[Epic 4G General] NeonMonster:
My phone survived today. From 8 until 5. So a good 9 hours. But that was with literally next to no usage. I turned it off around 10, and had it in airplane mode for majority of the day since I was at the ocean and had no service whatsover.

I'm gonna buy some extra batteries for those long days.

posted from a EPIC4G.
[Epic 4G General] akei1:
9 hours with airplane mode on most of the time? Did you stop drm, mediahub, and sprint hotspot from running in the background? Maybe the phone's not sleeping properly.

Seidio is developing a 3200 mah extended battery that you might be interested in for your long flights.
[Epic 4G General] ravizzle:
Wifi is much faster so if u got it at home use it. I know we all want our moneys worth but we also want the best user experience too, if u have wifi use it bc it is faster and also better on batt life. if u really want ur moneys worth disconnect ur home internet and just use wifi tether (my friend does that for last 4 months with his hero and sprint hasn't shut him down for outrageous data usage yet!)

And also wi-fi is great inside buildings where celluar signals might not be able to penetrate the walls very well from the towers outside.

But I do understand why a lot of people want to use 3G. We are paying a premium fee after all.

I absolutely have to use wi-fi inside one of my buildings though. There I get 0-1 signal bars, starts roaming, tws > 50%, and my 3G connection cuts out sometimes lol

[Epic 4G General] gophergun:
I get around 8 hours, which amounts to about 2.5 hours of screen on time with my usage patterns. Sadly, I used to get much better than that, at least double. While 8 hours is more than enough for me generally, it's still bothers me that something is clearly using a good deal of my battery. Already stopped the DRM and did the TWS fix.
[Epic 4G General] churro7:
try using spare parts?

cuz i get great life at home but half that at my moms where signal is crap
[Epic 4G General] ravizzle:
Well.sacramento isn't official yet so its not listed anywhere. maybe just turn on 4g and see if it works in fresno. Try downtown/busy areas first those are more likely.

That would be news to Sprint, because I use my Epic on 4G in and around NYC all the time.

You're getting 10 hours of use on 3G and you still don't see why a person would use wi-fi? Let's recap. You: no wi-fi, 10 hours of use. Me: wi-fi, 36-48 hours of use. Get it?

Also, wi-fi is much faster than even 4G.

i use the same rom, with mixup kernal and with no voice calls, i'm lucky if I get 12 hours.
[Epic 4G General] stud_muffler:
Over this long weekend (Columbus Day) my phone lasted 2 days 12 hours and 25 minutes between the charges (100% - 3%) in full stock but I have to admit I was somewhat limiting myself in phone use (just few calls, emails, text and some browsing) my screen on time was between 1,5 to 2 hrs.

I live in the very poor 3G and 4G area (tws was 21% during weekend), I do use wi-fi (never sleep) at home, screen at minimum brightness, all useless (drm, etc) services off. I do not use FB and Twitter. No JuiceDefender either. Did not use (were turned off) any bluetooth, 4G or GPS over weekend.

I have 3 gmail accounts to sync.

In my general use (workdays) phone lasts on average between 10 and 13 hrs depending on what I use it for.

:cool:
[Epic 4G General] robl45:
neutering the phone seems to be the only way to get it to last. turning off gps, bluetooth, thats like going back to the 1920's, I kinda expect that I should be able to leave them on and have them sync up with my car when I get in, doing it manually makes my wifes iphone way better than this. its really unacceptable to have to turn basic functions off to get the phone to last. and really the phone shouldn't need to be on minimum brightness. I guess we all just have to live with it. well the ones that want to actually just use there phone and not play with settings every 5 minutes.
[Epic 4G General] blazinazn:
What are you expectations? You have a phone with a 1Ghz processor and a 4" screen. This is faster than any computer in the 1920's and it can make phone calls. It has a 1500mAH battery in it. So what if you need to manually turn things on and off to make the battery last. I think it's unreasonable for people to want to use this thing for 48+ hours on a single battery charge.

Do you leave all your lights on when you leave your house? If you don't use then turn it off. How much easier can they make it with having the power widget built into the notification bar and the ability to adjust the brightness without any widgets or going through any menus.

Some people are never satisfied.
[Epic 4G General] Sh0wNuF:
I get 9 hours on a charge on work days. I work for a grounds crew and have no access to a charger but I listen to pandora all day and heavily surf the net, play games and watch movies on my breaks so 9 hours under that kind of usage is amazing to me. When I am not at work and using my phone like a normal person, texting, few phone calls and light web browsing then I can get around 14-18 hours on a single charge depending on the day
[Epic 4G General] churro7:
dang!!! what are your settings?
[Epic 4G General] Sh0wNuF:
I do the airplane mode hack and end drm after every boot which helps a lot, I also have the brightnss set fairly low, not all the way down but about 25%. Screen timeout at 30 secs, had it at 15 and got better battery life but it turned off too fast for me lol. Sync email and weather every hour but all other automatic updates are turned off except for background data

I definitely don't get 30 or 40 hours but I think the battery life is pretty damn good for a phone that does almost everything that I do on a computer
[Epic 4G General] churro7:
dang my settings are practically the same cept k9 mail is on push but only when backround sync is on so far no differences than before

i may do a hard reset
[Epic 4G General] Sh0wNuF:
How long have you had the phone for and have you let it drain completely a few times? I know my battery didn't last very long until I let it do that, and force closing drm and doing the airplane mode hack made a huge difference for me too
[Epic 4G General] ZenInsight:
I keep seeing the air plane mode hack. What is that exactly?
[Epic 4G General] muyoso:
Turn airplane mode on and then off. Thats pretty much it.

Don't know if it matters

I am using baked snack 1.3 rom and instead of clocking to 1.3ghz, i clocked it at 1.2 also i have set wifi policy to never sleep and I HAVE SEEN DRAMMATIC BATTERY improvements with this like that....

currently unplugged for 24 hours battery percentage is 36%

54%screen on time 2hrs 19 min

26%cell standby 24hrs 7 min tws 1%

17%phone idle 20 hrs 48 min

4%voice calls totaling 1 min 42 sec

2%wifi 16 hours11 mins 11 sec

my battery should be in the 50% region but work has no wifi so extra drainage there

sent about 7 emails 3 of those were very very lengthy

26 txt messages

used 4g at work during 30 minute lunch break

I GUESS TO SUM IT UP THOSE WITH BATTERY PROBLEMS THE SOULUTION IS TO SIMPLY USE WIFI AS MUCH AS POSSIBLE.... set wifi policy to never sleep

brightness is set to auto

this is all without the airplane mode toggle, or juice defender btw!

[Epic 4G General] djaward:
Ive been unplugged since 610 am. My battery is down to 75% and its already 11:10 am with light texting (about 20), 3 phone calls on bluetooth and minor phone setting changes (Brightness, sound etc.). I did the airplane mode thing, I have Task Killer on the phone and check it atleast once per hour and switch off any programs Im not using. Also, I go into settings, applications, running services and stop anything I dont use. Mostly the HUB thing. Anything else, I leave it one because I dont know if the phone needs it.

Phone unplugged at 610 am, during lunch is when I will use it and surf the web and twitter. When I get home tonight at about 530 or 6 pm, my phone will probably end up being at 20% or less. Im happy with that. I have a charger just in case I need to charge it up. Or if Im not going home.

Ok, so i ran both updates the 3.29.651.6 OTA update

Then the 3.29.651.5 OTA Update

and phone was stock no rooting or anything i was planning on rooting after the

updates where in place. but anyhow after the first OTA my android market app was missing. I figured well after i do the .5 one it might come back and i was wrong it is still missing. Is there a way to put it back on my evo manually ?

or is there something else i should do ?

Thanks for any help ,

[EVO 4G Q&A, Help & Troubleshooting] ms79723:
Well if you plan on rooting anyways, just root and flash a rooted version of the OTA update. If your market doesn't show up when you flash the rooted rom, you can always just download and flash Google apps.
[EVO 4G Q&A, Help & Troubleshooting] lbendor:
I have a similar problem. I was running what I think was a non rooted 1.47 ota update (friend phone). I say this because I attempted to use simple root a few months ago but it failed. I may have downloaded a PC36IMG.zip file to the sd card though. I say this becasue when I put the phone into recovery and select recovery it fails. It says the PC36IMG.zip image is missing.

Anyway, without recalling my rooting failure from before, today I applied the OTA 3.26 update. Everything went well except that the Market App is missing from the phone. I have not yet run the 3.29 OTA update. I have no idea how to get the market app back. I really don't care about doing a factory reset and loosing my apps and data. I woulld like to keep my pictures and videos though. I am afraid that my half baked simple root attempt from a few months ago has meesed up any prior recovery images. I don't beleive I have the ability to flash anyhing since I can not get passed the PC36img.zip error when choosing recovery from the power down volume recovery screen.

I am not sure what to do now.

I know I have been looking with certain apps I have. Nothing is hogging CPU or staying awake. Just seems that media is hogging network usage.

No problems with CPU or partial wake..

Help me please, I was running eclair 2.1 with the JH7 update rooted and lag fixed. I removed the lag fix and the ext2 files because I wanted to flash to stock (JF6). Everything went well with the stock flash and the Odin master clear. I was preparing to root and then install rom manager to flash Cog 2.2.5.5 but now I cannot re-root my device. I am trying to do so using OCLF from the market, but I click root device and it tells me I need to reboot and click apply the update.zip file. I can no longer get into recovery with the button combos (even though before I Odin'd I could do so) and I also tried some programs from the market that claim to boot your device into recovery. I had previous success with these apps and they no longer work either. I am also unfamiliar with adb commands so someone PLEASE HELP thank you in advance. Hopefully its an easy fix.

Setting up the ADB is simple. Here's a video tutorial along with some great instructions on that. Unlockr

The command you will use to boot into recovery is "adb reboot recovery".

If you want to use TeamViewer I could set it up for you remotely.
