UPDATED MY SETTINGS
So as many other users I've been having lots of problems with battery life. I've done so many things in an effort to try to improve battery life but it doesn't seem to improve as much as it has for other people
This is what I have done:
Installed Baked Snack 9.7
Have brightness set to automatic
Changed the preferred network type GSM Auto (PRL) to CDMA Auto (PRL)
Installed Juice Defender
Installed SetCPU and have it so that my phone is under clocked to 245mhz when screen is off.
Turned haptic feedback off
Turned Off Auto-Sync
Manage my running applications with Advanced Task Manager and have it so that it ends apps every 30 minutes.
Flashed the newest Radio
Reconditioned my battery like HTC representatives suggested
Even with all these changes I'm lucky to get 10 hours of battery with moderate use. Far below the 16-20 hours that other users claim to get.
I don't understand why my battery life is so bad. Any tips? Maybe something I did wrong?

Even with all these changes I'm lucky to get 10 hours of battery. Far below the 16-20 hours that other users claim to get. I use my phone mainly for texting, send maybe 200 per day. Connect to the marketplace for about 20 minutes in total and and never watch youtube videos or surf the web. I spend around 20 minutes a day on the phone at most.

Perform the HTC suggested battery cycling.
Charge until full, unplug, recharge, unplug, recharge, turn off, recharge, turn on, recharge for a few times.
No comment on the battery life as I have no problems but why did you want this phone in the first place if you only text and don't use the internet? I would own a Blackberry or Nokia E71 if I used my phone in that way.

I expected someone to say that, I used the internet heavily for the first few days and saw the horrible battery life so I started limiting how much I went on and this is how much battery I'm getting now. I do use apps sometimes though

I tried that, it worked on the first day but then battery went back to normal the day afterwards
Try running dcpowertop via ADB to see if something is causing a lot of wakes and preventing your phone from sleeping. Also try running Systempanel monitoring to see what is using up the CPU time and draining the battery.
Also, this does nothing unless you are running a custom kernel (You didn't mention if you were, so just sayin'):
Installed the OverclockWidget and set it so that when the screen is off the processor runs at 245 mhz.

But, even so, you should be well above 10hrs battery life with the other changes you made.

He's better off with this deal really, many members have purchased them (including myself) and they perform near as well, or just as well as the OEM battery - but you get 2 of them, AND a charger:

Most batteries above 1500mAh do not even perform close to what they say they should. Check out batteryboss.org for details.

I'll give dcpowertop a try.
I just uninstalled overclockwidget and installed SetCPU instead, the new version has the perflock disabler which should allow me to underclock.
If you are in a sketchy service area, your battery will drain fast.
How much do u use your phone? That's right there the key when other people say ILL GET 16-20 HOURS OF BATTERY LIFE. Yes cause they don use it as much as i do, maybe u use.ur phone hardcore too, texting mms back and forward like no joke. Lots of them. I do over 600 just the morning. So my battery die around 2 then i use my hero battery that i have as back up. Its BS when other ones say that they get crazy amount of battery. Yes it can be but cause they don't use the phone as much, my buddie has a iphone 4 and we tested it against the evo and yes he's better but not crazy better like when i was on 50% left he was on 62-65 % my phone died first he was on 10% left. ...

Ok, so SetCPU does actually work and I have successfully downclocked my phone.
If you send 200 texts per day and do little else, as smart phone is not for you. Get a more basic phone that would give you 3-4 days of heavy usage.

That's very strange especially with how little you use it now to try to get more battery life.
Only other thing I can't think of that's not on your list is disabling Google Talk auto sign-in. Not that I think that will make up the difference you are seeing, but it's something else to try. You seem to be doing everything right, maybe try a clean ROM install?

Im running "bakedsnacks" latest version, try that. Ive been having insane battery life. It already has the undervolting kernel in it. Give it a try, u have nothing to lose. But you have to remember that the Evo is a beast .
What is your dcpowertop

Follow the Battery Recalibration instructions in the cyanogenmod wiki.
Doing this, I was at 73% after 26 hours unplugged. Yes, I was using the phone: 20 Text messages, about 20 minutes of pocket empires, 20 minutes of another game, WiFi enabled for most of those hours, and I even ran the "Relax and Sleep" app for half an hour when I went to bed.

You don't need to turn off all those features to get better battery life.
If you really have trouble, simply downclock the cpu to something like 460 Mhz and you battery life will double.
Then have someone make an undervolted kernel for you, and your battery life will triple.
When you say managing your apps with ATM? Are you using it to kill your processes? You probably don't need to manually or even schedule task killing with the lowmemkiller in DC.
One thing you didn't mention is what your signal strength in the area is. My 3g reception is utter trash in my office, so I have an extra cable to keep it charged. Overall, my phone drops about 1% while idle and I don't have any task management or cpu throttling apps going.
Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!
Chris R.
I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).
Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.
I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience
Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.
juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well
JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........
here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps
Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?
I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.
Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.
Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.
Do you have juice defender installed?
Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.
That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)
I think the consensus is that our Galaxy does not really have a "good" battery life. But how bad is it really?
Can you share your experience with regards to real life in terms of % drop during active use and non-use? (pls dont give built in battery stat/usage which I think is pretty useless for comparison)
Pls try to keep to following format so that readers can gauge their phone battery life:
===================
Phone: SGS I9000, DXJG4, voodoo lagfix 3.0, non-root, 3G+background data+Sync(gmail)+Location(wireless)=ON, BT/GPS/Wifi=OFF, auto-brightness, live wallpaper, Friends+weather+stock widgets update hourly.
Stand-by (overnight): 1.46% drop per hour (i.e. approx 12% drop over 8+hrs)
Active use: 23% drop per hour (3G web surfing with Opera Mini)
===================
Phone: Iphone 3GS, 4.02, non-JB, 3G+Push/sync(gmail)=ON, wifi/BT=OFF, auto-brightness.
Stand-by: 0.7% drop per hour
Active Use: 19% drop per hour (3G surfing with Opera Mini)
====================
Phone: HTC Touch HD (WM6.1), 3G+PULL gmail (15min)=ON, wifi/BT=OFF, auto-brightness, Sense UI (all widgets manual update)
Stand-by: 0.9% drop per hour
Active Use: 25% drop per hour (3G web surfing with Opera Mini)
The problem with this, is that batteries aren't equal, some people are using possibly counterfeit batteries, and some people batteries might not be calibrated.. Maybe it would be better to run the battery down to 0%?
if having issue with your battery and your rooted just run the command to remove /data/system/batterystats.bin then the reboot command with ADB it will improve your battery big time... this should be done when the battery is low like 10%..I did this and it took it from 10% to 38% and I got almost a 1/2 more out of my battery..
when ever you flash Roms you should clear the batterystats.bin.. when you reboot the android system will make a new file.
Code:
adb shell
su
rm /data/system/batterystats.bin
reboot
Just to set up the expectations here, its not always that clearing the battery stats work.. its just a history of the usage anyway.
depending on roms etc.. i had from 1% / hour issue battery drain to barely 0.3% per hour drain both in idle / stand by of course (it lasts forever on JPK in 2G on standby for example)
don't know what really causes the 1%/hour bug
in use i couldnt tell but i feel like it uses more than other phones unless you're watching black ^^
Apple has really good standby battery consumption on all their devices but SGS Probably has among the best battery life during active use.
I know it is quite the "norm" to have a 1-2% per hour drain on standby with 3G and sync on. I had the same drop using JF3 and the later JG4 firmware. There is no diff before and after lagfix.
I am not too bothered about standby drain but I am quite unhappy with the active use drain of 23% per hour.

If by active, you mean typically a form of internet or communication a lot of that blame goes on the application and consumer, we can't have high expectations for battery life from a 4.0" that is producing white backgrounds. A comparison to a 3.5" device that uses an LCD screen is just flat out unfair, there are other devices that you could compare to, say Droid X, which will also have better battery life, but that also doesn't really give more of a right to complain.
I'm surprised that there isn't better access to white on black internet reading, much like how the e-readers are set up. Is there nothing, does dolphin or mozilla have anything like this?
Right now I'm using 10% per hour using it as Mp3 player. Thats what juice plotter tells me. Using OCLF ontop of Voodoo lag fix under JM8 . I'm going to flash JPM tonight and just use OCLF as Voodoo isn't working with Froyo YET. But seriously the phone flies but battery life is unacceptable. When I use 3g to browse its like 20+% a hour minimal. I blame lag fixes as voodoo is known to kill batteries
battery drain
Wow! yesterday when I went to bed I had 72% full battery on my new galaxy s and this morning I found my telephone dead with 0% battery. the phone has standard XXJM1 firmware the only thing that I did is rooting. Yesterday I have installed Navigon, Igo, and Timeriffic on this phone, I also have setcpu running there. There were no issues before yesterday though, so I assume setcpu has nothing to fo with the problem. Any one has similar issue?
Well I don't have anything like your setup (jm8 + voodoo-oc + doc superslim here) but I believe I was experiencing a similar issue and it was not related to voodoo (checked the indicators listed on project-voodoo.org)... Maybe that is setcpu. You might want to try that because I have none of the other apps you listed.
Sent from my GT-I9000 using XDA App
I recently experienced similar issues and found out about some apps that prevented my phone from going into standby state or constantly smoking CPU time. Those were Tango and SwitchPro Widget, I'm not sure about Skype. Uninstalled all of them and now everything's fine again.
I suppose you have issues with apps gone crazy, too, as a battery drain to this extend is very unlikely to be caused by a lagfix or something like that. Suggest you uninstall recently installed apps one by one and see if the situation improves. If you have some 3$ spare, consider buying SystemPanel -> hxxp://goo.gl/aUxO which does a great job of monitoring your android system for CPU huggers.
Please share your experiences.

I also have thoughts about SetCPU and I revealed another problem - I setup profile in SetCPU for screen off event to limit CPU to 200Mhz and turn on powersave mode - this caused my phone stuck in sleeping mode, only battery-out would solve the issue, I have corrected this profile to 400Mhz-200Mhz and conservative mode, so far no second issue. Will see after overnight.
Well, the battery on Galaxy S goes very fast, will look for other solutions to longer battery life. I want it to be at least 2 days.

Right now I'm using 10% per hour using it as Mp3 player. Thats what juice plotter tells me. Using OCLF ontop of Voodoo lag fix under JM8 . I'm going to flash JPM tonight and just use OCLF as Voodoo isn't working with Froyo YET. But seriously the phone flies but battery life is unacceptable. When I use 3g to browse its like 20+% a hour minimal. I blame lag fixes as voodoo is known to kill batteries

bs
i had voodoo with 1% battery drop in standby fresh install data wipe
i had voodoo with 0.2% battery drop in standby fresh reinstall data wipe
Didn't find out the difference
the truth is elsewhere
Let's see how it goes in froyo.
I had some high battery drain issues with the 'root' part of OCLF. I uninstalled it and installed voodoo and it seems to have gone away now. Battery life is definitely a little better than my Desire.
Btw, someone mentioned running only on 2G. How do you do that? I havent been able to find any option to disable the 3G radio (messing the apn settings doesnt turn off the radio...does it?)
my opinion
SGS is the best android phone because of battery.
compared to desire sgs holds 4 times more when surfing the web.
i allways foget to disable gps, wifi, i use full screen light. and it holds 40 hours always. im realy happy with that. had g1 before and the best was if it hold from morning to evening, but if much of use it lasted in 4 hours.
my frien has desire. he disconnects charger in the morning, and connects in the evening.
i need 2 battery a day, if i don't top it up when i by my PC/laptop/car

I'm really curious on how you manage to have 40hrs battery life. My SGS only have 18hrs tops, and that's with what I classify as conservative usage. Most of the time it only lasted 12-14hrs. So please do share some tips and tricks if you have some
( oh, I've set the screen to the lowest brightness setting, I don't use live wallpaper and use a dark colored wallpaper to conserve battery)

I think the battery life is ok on sgs. I use it only on 2g and for me it last like 4days. If i activate 3g then it laat like 2 days.

I had searched previously and read some things about this "bump" charging stuff supposedly getting you many more hours of usage on a normal schedule.
Actually, guess I should preface with some background info. This is my first android phone, but I've been watching since 1.6 came out. So, the day I got my Epic it was rooted and I flashed Nebula ROM on it. I also tried out Epic Experience, but was more pleased with Nebula. Of course I'm running DK28 with the modem fix.
On to my question. What can be done to increase battery life on a fairly undemanding schedule, without causing the device itself to operate less smoothly?
I tried several of the bump charging methods I saw, but I'm sitting at 33% battery after 5:45.
I'm going to feel dumb if this is actually average and I'm just expecting too much, haha.
Thank you, kindly.

You can try calibrating your battery. If you don't know how, well here's some instructions:
To do this, all you have to do is let your battery completely drain. Then while the phone is off, charge it for around eight hours straight without turning the phone on (have it just showing the battery icon).
Since you are already at 33% or so, I'd suggest just letting it drain today, and have it just charge overnight.
I, too, am running the Nebula Rom, but I haven't tested it for a full day without charging it yet. So, you can try calibrating the battery if you would like to see if you would get any improvement, but in my opinion, 33% at 5:45 sounds great. I'd be satisfied with that.
Please let me know how it all turns out.
Hope this helps!

Thank you for the speedy reply, I will try that.
I wasn't really expecting 33%, but more around 50%. I've only sent three texts today on it (as I was trying to see how well it'd hold up) and so I assumed battery life would be fairly high. But I am also living in an area with extremely poor coverage, so bad that it'll start searching for signal if I move the phone 2 feet away. So maybe it is trying to acquire a signal often.
I'll report back in the morning. Any other advice/ideas would be greatly appreciated.

Well, there's basic things as well.
Check to see if Data Roaming is on, make the brightness Auto, no live wallpaper, no bluetooth, no GPS, No background data/Accounts Sync.
But you shouldn't have to do ALL of those. Just a couple if you haven't already to boost the battery a little.
And yes, searching for a signal could be the problem.
And only three texts? Nothing else? Maybe there is something wrong.
Tell me the results tomorrow after calibrating the battery.
I'm using midnight rom and I'm at 20h26m and 33% with moderate usage. You can try recalibrate and wipe 3x b4 install the rom. It might help. Good luck.

Alright, it's 9:20 EST and I'm starting off with 96% battery life. I'll gauge how it holds up through "normal" usage, which is somewhat less conservative. Wifi will be on nearly constantly, my signal will be weak unless I leave, autosync is set to hourly with background data.
I normally get about 12-16 hours on what I call moderate use.
I leave gps on all the time. I make ~6-10 calls a day for 5-30 minutes. I send and receive ~30 texts a day. I'll put an hour or two worth of internet time per day. (not watching videos)
I kill the drm and friend locator services on every boot. This helped my battery life a lot.
It does help to train your battery dragon occasionally.

Ya, that's the kind of performance I'd like. Are you running stock or do you have a rom installed? Also, what DRM and Friend Locater? Never heard of the latter.

Are you saying to turn Data Roaming on or off? I could come up with a reason it would help either way, so do tell.
Same thing with Auto brightness, I would think that actually uses more battery than a fixed lower/medium brightness.
Do people on here really leave Sync and GPS off?
Compared to these settings, I'm completely lazy, and still get good battery life.

Turn off Data Roaming. The reason being is that with it on, your network will constantly search for data, and that drains the battery. The brightness I am actually not sure on. I have had better results with auto rather than, say, 0%.
If you get good battery life already, that's fine. But auto-sync isn't really necessary in my opinion.

Alright, it's been 5:33 since it's been unplugged and I'm sitting at 68%. This is with wifi on the entire time, brightness set to auto, and data roaming off (no need for it to be on, I was considering toggling it based on my location in Tasker). Sync is on and I rarely have use for GPS in my day-to-day so that is off.
So I think the calibration as recommended by Acer1096xxx has effected the life of my battery for the better. Thank you, once again.
Hopefully this thread will help others out in the long run. I'll continue to monitor my activity and battery life.
EDIT: 57% as of 5 o'clock. Had to plug it in because I'd be going out tonight doing things. Overall, this is about the performance I was hoping.
Hey guys im in the process of doing a little experiment to see actually how much Juice Defender with Ultimate Juice actually improves the battery life on my Evo4G. I'm sure this has been done somewhere else i just couldn't find it so i decided to do the experiment myself and post my findings this may be useful to some people or may not!
Phone: Evo 4G
ROM: Cyanogen Mod 6.1.2
Kernal: Zendroid BFS @ 1.52ghz w/ smartass scaling
Launcher: Go Launcher
-----------------------------------------------------------------------------
Phone running Juice Defender With Ultimate Juice
Phone Unplugged At 11:42am
Phone Died At 8:59pm
Usage: For the most part it was moderate use, no gaming, 2 calls lasting for a total of aproximatly 45 minutes. 120 texts were sent and received 146 within the time frame. There was no browser usage just mostly texting like i said. 3 Pictures were taken. No Wifi. Bluetooth or 4G used either.
-----------------------------------------------------------------------------
Phone running without Juice Defender With Ultimate Juice
Phone Unplugged At: 2:50pm
Phone Died At: Never
Usage: Well my phone has been unplugged since 2:50pm and its now 12:35am and my battery is sitting at 55%. Weird... very weird. I had about the same usage as yesterday i played 1 game for a total of probably 10minutes and installed 4 apps. A had wifi enabled for probably an hour total.
-----------------------------------------------------------------------------
Final Thought: I think Juice Defender doesnt help at all, infact it seems to hurt your battery more than anything. I think it may be because its constantly turning things off and back on consuming battery? Thats the only thing i can think of. Does anyone else have any thoughts on why this is? Using Juice Defender reduced my battery life dramatically it almost cut its life in half as a matter of fact. Please share your thoughts on why this is people!

thanks for the info. i try to tell people that juice defender doesn't help. but no one listens so i gave up and just tell them cool app and walk away lol.
very helpful post. I noticed too it doesnt seem to really help it just monitors mobile data and turns it off when screen is off and occasionally powers it on to download emails and ****. I dont like it because i like to kno when i get an email instantly versus it checking every 30 min.
I also found that juice defender seemed to have a negligible impact on my battery life while also decreasing speed of sync/convenience. You'll notice that it also makes android system skyrocket towards the top of the battery use list.
On a related note, I also found that setcpu profiles don't have an impact on battery life and may even hurt.
Ultimately, android is optimized to manage a lot of these things on its own and introducing an app that consumes battery both monitoring and brute forcing some of these activities doesn't make sense. The only active monitoring app I use now is Tasker for some specialized automation activities.
i cant believe this is an app that most people recommend to improve battery life tho. Especially with how much it hurts rather than helps. Very disappointing.
It has helped mine because I use the widget to manually shut it off and on. I don't let it control it. Since the epic doesn't have the shut off data in the power menu its good for me. Otherwise I agree with you all. I keep my data off until I need it to look something up. Personal preference. But hey it does shut my data off when I tell it to.

Rom: Never stock, but always with some Gingerbread.
I had been using juice defender and setcpu for a while trying to get the best battery life, but I ditched them both about a month ago and I'm getting better life than ever before lol
I've got 58% left in the battery and the phone has been up for 32 hours. I thought I was helping by micromanaging the phone with JD but I think it was really just hurting it.

32 hours up and only down to 58%? Mind if I ask how you set thigns up that your phone is so energy efficient?
It was a great application, Donut times, it literally made my Magic 32a survive the day against the not-even-a-day battery life at those times. Nowadays it is simply useless due to android better app management.
Hmmm...I have been using this for a few months now and I've seen dramatic improvement in my battery life. I usually unplug my phone at 7 each morning and by noon on moderate usage days I'm at 60%. Using JuiceDefender, my phone is typically at 80%. By 5pm with its only at %60. Normally I would get home at 5 and it would be around 30%. Interesting.
Running Samsung Captivate
Stock Android Eclair 2.1
Rooted
Zeam Launcher
With more iterations of Android they are improving power managment, Ya back a little bit ago this helped some people alittle it closing out processes and way to handle things but with android development alot of this stuff is getting worked into the OS, basically now all your doing is running a app constantley that does something handled by the OS now in newer builds.
I wonder in some cases if the juice defender and the OS both trying to do power management if it can actually cause more power loss due to a conflict in the two trying to controll items. Of course OS should have higher pid but could cause some of your increased power drain using both
try the beta
im using it on my epic and my evo i think it helps both but i am also using the free beta i dont think the regular one works
i'm shocked there's even a thread for this. i put it on a stock epic and it made a WORLD of difference.. especially in locations where my signal was poor and evdo service kept dropping. my issues with it are of a different nature. seems to get corrupt alot and the wifi locations service sucks
Hmm, i'm confused on how this could actually hurt battery life, especially by the amount you displayed unless you have it doing all kinds of other management as well. I have mine setup to only manage the data APN, disabling on screen off, and seem to have gained decent battery life from it. The widget to toggle data on/jd on/off is very handy as well.
Pretty sure android doesn't do anything natively that turns off data when phone is at rest/screen off, does it? Someone please correct me if i'm wrong.
I will admit, the new versions of JD do seem to be pretty bloated and sluggish.. i've been on the fence of whether to remove or not... The main reason i keep it on my device is because i work in a basement and get about 65% TWS and severe battery drain from that. With JD managing 3G, it helps mitigate that somewhat, and having it be automatic is much more convenient than toggling it manually all the time.
I may have to join you on some testing, because if JD is not gaining me anything, i'll definately be removing it as it sometimes causes some initial sluggishness when turning the screen on. From daily usage experiences (and i watch it like a hawk), my battery life has definately not been made worse.. older versions seemed to net me more life, and i'm undecided on the new versions. Not enough time with it on/off to decide yet.
Most Def Work
JD helps... it will slow down notifications and stuff, if you need always on data then this won't help. However, during the day I'm usually already online and don't need non-stop notifications and if you use JuicePlotter you can clearly see that while sitting idle with JuiceDefender on you use significantly less battery than if you don't have JuiceDefender active and have it sitting idle.
for those that think jd works...
are you using the free, pro, or ultimate version? looking to buy if it really saves battery life.
which configs did you use? I had it a few months ago and my battery did actually improve. Trying some different settings makes a huge improvement.
I am using superpower now. (from XDA actually) And this is really working, it also takes some configuration, but eventually it will benefit your battery life.
Superpower turns data to 2g when your screen is off, disables wifi and bluetooth and sets your cpu to a 400mhz cap (at least with my phone) I noticed a 1% overnight drain and a 200% increase in battery life. (basically I do two days with heavy use vs. one day before)
Hope this helps some people!
The only thing that actually changes the battery in an evo is a kernel. No quick fix app is going to help how your system interacts with your battery! Senseui is garbage and it sucks up battery life like no bodies business!
