I Finally Did It! (24 Hour Battery)

I have been desperately trying for SEVERAL months to find a way to get my Samsung Epic to last ONE DAY. Many of you might say thats EASY but not for me. You see I am a POWER USER. Not one of those send a few text message, listen to some music, play a game or 2 users. I actually TALK on my phone a LOT.
I purchased a Yoobao 2800 MAH battery a couple months ago, thinking it would solve my problems and to my dismay I could ONLY get about 5-6 hours with the way I use my phone. So I began searching for apps and configurations that would help me achieve my 24 Hour goal and yesterday I finally found a configuration that works.....
My Results
Battery Life 25 Hours which included 4 HOURS OF ACTUAL TALK TIME W/ BLUETOOTH USAGE
Including 3 email accounts (2 Yahoo set to 1 hour check and 1 Corporate "PUSH" email)
A WHOLE GANG Of TEXT AND PICTURE MESSAGES...LOL
What I Have
Samsung Epic w/Yoobao 2800 MAH Battery
Running Stock Rooted EG22 (Leak) and Generation X "Green" theme.
What I used
Set CPU:
Set up profiles for maximum battery save when screen was OFF and when battery went below 30 percent
Juice defender (Free Version)
Tweaked for maximum efficiency using advanced settings
What I did
Themed everything as dark as possible (Go SMS Pro, Go Dialer, Go Contacts)
No Live wallpaper (Ovious...lol)
My Findings:
Contrary to popular belief....Tasks running in the background IS NOT the biggest source of battery drain. HAVING YOUR SCREEN ON IS! I was having NO success with any of the top task killers so I STOPPED USING THEM ALTOGETHER. All they seem to do is run constantly in the background (Even when the screen is off) killing apps that will RESTART themselves anyway after a few seconds. Juice defender works in a different way. By cutting off the data connection when the screen goes dark. That means any time Ii was on a call and the screen was dark, my data was cut off. (I dont usually need it when I am on the phone anyway) During this entire process I had a rather light wallpaper on my phone. so Im sure I could probably have saved a lil more battery if I wanted to.
Hopefully this will help some people get more battery life out of their epics. After all, whats the point in having a great phone if you can only use it (the way it was INTENDED) for a few hours.
Good Day To All!

lolz
im runnin ec05, srf1.2 rom, bright red & black theme(transmattered reds made by me) pulldown animation, stock battery, no memory mods, live wallpaper(my theme is mostly transparent so the live wallpaper is playing almost all the time), play pandora average of 4-5hrs a day, constantly checking fb xda email market(i have 120ish apps lol), & i get about 13hrs a charge...
you should try those changes on srf1.2 rom if you already havent... some people running similar setups have reported 2 full days or more...
but instead of set cpu you should try voltage control

Pretty sure when you get a phone call it shuts off 3G anyways. Atleast whenever My phone rings my 3G symbol vanishes completely.
Congrats on the 25hours though

I dont think thats true... I've been on a call using speakerphone and 4g data at the same time... I think 4g data still works if you are on a call

The key to good battery life is making sure your phone is sleeping properly when not in use. If CPU Spy shows 100Mhz much higher than deep sleep, then you got something that is keeping your phone from sleeping. I had a problem with some HP printer monitor on one of my computers pinging my phone constantly on my wifi network that would kill my battery if I let it sit with wifi on at home.

In the bottom right corner up there 1day 8 hours at 39%. I run srf, genocide, juwe ram tweaks, and set cpu with profiles to run the frequency lower as the day goes on.
Edit: I see now that that is a very ****ty picture. Man I just can't get screenshots right at all..
Cd's or tapes?

Talking on the phone and the 3g network use the same antenna, so you can only do one or the other. 4g and wifi use a different antenna so they will still work for data while on the phone.

Its not the antenna its the chipset. Bluetooth and wifi share the same antenna but both can be used at the same time.

After I flashed the EG22 Modem and Leak I had a 25 hr battery, but now I get about 10 hrs. Weird.

I have juice defender but I never use it.

I saw roughly the same thing. Incredible battery life for the first day or two, then it would refuse to charge either of two batteries past 60%.

IS THAT WITH A STOCK BATTERY?!?
Thats unbelievable....

Until the newest RandomRom 2.3 Hawk I had the same problem trying to get my phone to last 24 hours. Now I have the RandomRom 2.3 Hawk installed with bloatware Removed, voodoo sound V9 module loaded, busy box pro and golauncher ex with over 100 apps also. 27 hours and I still have 14% battery life and that has been after using 4g for about 3 hours, flashlight for about 1 hour(teslaLED), played games for about 2 hours combined, sent about 40 emails, texted all day(about 150 texts), browsed the web for about 1 hour, watch some youtube videos for about 30 minutes and used navigation for about 30 minutes(coPilot). That is also with weather bug auto updating every hour and gmail sync'd to do its thing automatically. I am happier than I could ever describe now...I think I will finally leave my phone alone for a while now and stop flashing a million roms since I feel I have the best made for 2.3.4 now.

battery
I get about 18 to 20 hours of normal everyday use out of EG22 but i stay on wifi. on ec05 the most i could get is 6 hours, bottom line no matter what i tried. and thats with a stock battery.

Defy Battery Issue

So I successfully installed Cynogenmod 7.2 but the 99% battery thing is pissing me off. Yes I did use BatteryCalibrator and also tried deleting the battery file through advanced option via CWM.
But I still have the 99% battery thing. Whenever my cell reaches 100% and I unplug it and it goes to 99 instantly too. Any help? I seached almost everything but no help.

pure logic bro...it's 100% when u have it plugged in and then ofc it drops to 99% because it looses some mili amps
if u don't want to see that..just don't use any soft that shows u battery percentage

well maybe because of your battery usage in time, because it happens to me also, so maybe our battery has a lot of usage and in a future we need to change battery :/

The same problem here, i tried many batt fix but no one works. It has started since i first installed CM7.2 ( mine is defy plus ). Still keep searching. It's because of the kernel i guess. Anyway to change it ?

Do you have baterry drops while using? Like from 30% to 15% ? Cause i've found that and that's not cool
Sent from my MB525 using xda premium

Hi guys, I wouldn't accuse ROM or kernel, more I wouldn't bother too much, till I do not have to charge twice a day.
I have the same issues with two different phones at home, different kernels and different ROMs. Though I tried batt calibration and CWM wipe, it does not help. Both phones never reach 100% - go to 99% even if you charge for several hours then.
Sometimes I have 7% drop per 8 hours, sometimes 5% in 20 minutes - both cases only 2G is working (and of course some mess in background ;-)). I would rather accuse some applications working in background. Anyway rebooting helps.
For the case of sudden drop by 15% - do you have any task killer killing your batt widget? Or, may be, your battery widget is refreshed once per hour or so? Just proposals to check. (it is funny when task killer kills your clock widget - might be a lot of fun when you suddnely find you are two hours late. Know such case)

I'm having the exacte same problem with battery drops except that in my case i have 2 drops instead of 1, the first one at 70% and the second one at 30% or so...happened with 2 roms, stock and cm7.2...
Buying a new battery will most likely fix it ...isnt it??

yea same thing to my defy red Lens. Started noticing it happen when I switched to cm7.1 from jboogies rom awhile ago. Ever since then I thought it was normal. But know its just getting annoying. What battery fixes have you tried maybe I can try them and hope for the best.

The 100% to 99% when you unplug is not a problem. its because when it calculates the battery "%" it always takes the lower value
Example:
Battery level is 80.9 -> shows 80
Battery level is 99.999999999 -> it shows 99!
that is not a bug

Mine is also having this problem. Jumps from 30% to 20% instantly if the phone has been fully charged. However if I only charge it to 50% it does not jump.

WHen i used CM7 or CM9, there was no drop. But when i use MUIU Pikachu, i have drop ! from 70-49%
---------- Post added at 04:31 PM ---------- Previous post was at 04:28 PM ----------
NOw i am using wiui and cant charge more than 81% ( defy plus )

Mine also drops instantly to 99% after unplugging, however it does not seem to affect the functionality of my phone. I got usually 40ish hours with ms2ginger4 and now I am testing it with quarx ics 0413 defy+ build to see what that drain is.
Also every time I install a new rom I use.

Works great for battery charge issues

Well in my case the problems came when I started changing roms frequently ... bought defy around September last year, started the custom rom changing week after purchase ( rom changing frequency was about a different a week ) ... and battery skips started happening around December . .... and from then m always searching for a solution to it ..... unsuccessfully

Stuck at 100%?

My battery is stuck at 100% and won't go down. Normally I'm not complaining about battery life in this way, but this is really weird. I'm running Paradigm by the way.

Fully charge your battery, then wipe your battery stats in CWM. If that doesn't work, then it's probably an issue with the ROM.

That didn't help, so I flashed the euroskank cm10 nightly, and I still have the issue. Ahhhh. I don't want to have more issues with this tablet. Any other recommendations?

Go back to completely stock and see if it works. Then you'll at least know if it's software related.
Sent from my Transformer TF101 using xda premium

I'm now stock unrooted, all set up. I'll run stock for now until the new Paradigm hits. Then, I'll try rerooting. If I run into this issue again on stock then I'll call Google, and probably just return it. I don't really want a third one. BTW, when it happened, recovery would also show 100% as a reading, but would usually go down to 99% after a while, and then when I rebooted, it would discharge at a normal rate, but would never compensate for the weird extra time at 100%. Does this point to a software or hardware issue?

Is it plugged in?

Lol no. It says discharging, 100%. But my screen was on for 31 min, and it said that and I'm pretty sure the n7 isn't rated for 30+ hrs screen on time.

majority of the time, i was busy at work. but, ive seen and some other people have seen 2+ hours at 100% with use. so, depending how long hes been watching it drop, it might be normal. especially since he said he saw it drop in recovery then drop after he booted up.

As I said earlier, battery was at 100% for 31 minutes of SCREEN ON. Then I rebooted, cleared caches, hung around in recovery for 5-10 min, saw it hit 99%, rebooted, and system said 99%. Like I said, that would mean I could get 30 HOURS of screen on time. NO WAY is that possible.

that doesnt mean that you would get 31 hours. what you just described is normal and youre freaking out for nothing.

Maybe you have a super battery saving kernel try just to run it flat, then do a charge while the device is off

my first day with the n7.. happy now? i ended up getting over 7 hours screen on time. you cant extrapolate 30 hours from it that way like you were doing.

This happened to me too.
After taking it off the charger it wouldn't go down. Now keep in mind my case I had left it overnight and hadn't played with it so I had at least a day in my battery info on 100%. Rebooted, then tried factory reset, all the normal stuff to try and nothing. Then tried CWM wiped everything then even reflashed the ROM and tried a different kernel after going back to complete stock it started decharging finally but now dies at 20%. It just turns off doesnt even shut down, and when it finally gets enough juice to start it would flash a little text message in the upper left "show low low battery logo". I finally managed after flashing CM10 then back to stock and charging and decharging a few times and deleting batterystats.bin from data and pulling the charger while it was booting to get it to realize there was an inbetween 0 and 17% and it sat charging for a while on 0, where it had just jumped straight to 18 but is now charging up normally again, that is where I am at.
I've got like 3 days left on my exchange with GameStop and I'm back and forth whether I should just take it back because I don't have any of this screen lift banter every talks about but don't want to end up with a faulty battery because it only just started here like last week.

People, the nexus 7's battery is not that good that it can go for hours without dropping 1%!!!
It could be that there is a problem with the battery indicator. That could be hardware or software.

yup. remember, theres no 3G/4G radio sucking the battery juice dry.

Well, flash all stock, and watch the battery meter.
Flash a custom rom with stock kernel and watch the battery meter.
Flash a custom rom and a custom kernel and watch the battery meter, what do you get?
FYI, look at the screen on and total time at 50% battery, i bet you won't have double those time by time you hit 1% either.
You can't look at the first 30 minutes and go crazy over it. That's as bad as watching wakelocks and going crazy over wakelocks before you have an issue, wakelocks are normal and needed.
Stop obsessing, enjoy the tablet.

Best Battery ROM

OK so i installed almost every ROM on there and here is what i found.
TOP.
:good: CleanGB ---- Takes the crown, super fast battery charge in less then 45minutes the battery is full. Over a period of 8 hours in stand by(as i sleep) the battery did not drop at all.
CM9 ---- Took over 2.5 hours to charge the battery, in 8 hours it dropped 12% battery life.
CM7 --- Charged in 1.7 hours and dropped 17% battery in 8 hours.
The rest were terrible, I would not even bother.
All configuration were the same. Everything off (wifi, gps, etc)
After all i installed CleanGB again at the end. And guess what in the past 8 hours battery did not at all in standby. My phone last 3 days on the same battery charge again, with normal to moderate use.
This was the same battery same settings.
Let me know if you guys found something else.
GUI experience:
CleanGB is cool and simple, however i wish they would upgrade to Android 4
CM9 has an really cool interface but i can not tolerate the battery drain issue.
CM7 is the worst of the two, not so great GUI and bad battery life.
If you still think im crazy install CleanGB and see for yourself. CM9 just needs to focus on the battery drain.
CleanGB is more focused on the phone working as it should and they did that really well. :good:

CM10 isn't horrible, I think it's a step above CM9 honestly, Mine charges over night so i don't know how much it would drain. during a day of moderate use (texting, reading XDA and what not) I'm generally about 65% or so (If not higher)

I will try CM10, i didt think it was available for the epic. I do like the CM9 look but i hate the batter if CM10 is better then ill be happy.
Thank you. I will report findings.

The People's ROM. It's as good as CleanGB (ran that for several months) and is based off the latest official release (FC09).
My one personal cheat is to use the CleanGB kernel with TPR, so that may be why I get fantastic battery life.

Never going to happen. CleanGB (and TPR) are both stock TouchWiz based ROMs and it's not too likely that Sprint will offer an ICS update for the Epic.

ROFL!!! :good:
As to the topic, I have seen it posted by a massive number of users, that CM7 had much better battery life than CM9.
In fact, the number one reason I saw posted as to why people went back to CM7, after checking out CM9, was battery life.

As to the topic, I have seen it posted by a massive number of users, that CM7 had much better battery life than CM9.

This 100%

I' am on Cut & Paste Rom FC09 and this has given be best battery life as of today. I had clean GB earlier (sometime back) after which i tried all the other Roms (AOKP - ICS, MIUI - ICS, RandomRom 5.1) and then decided to try C&P and man this rocks !
I have got a battery life of 2 days with a talk time (voice call) of 4 hours and thats the best i have seen till now among all of the Roms on my phone

legendary.mtd + gps fix is just as good as cleanGB plus it has the 15 toggle mod

try AOKP, people says it has better bettery life than CM9, so you can keep the "cool interface" while saving battery lol. Me myself never bother with battery as long as it last more than 1 hours. Always carrying one of those portable charger, If the battery is low then charge it haha.

The rest are horrible..? Thats not very nice, if your looking for a battery saving ROM, you should definitely try The Peoples Rom (TPR) and if your not satisfied with thatt, try Cut&Paste Rom. Those two ROM's are awesome.

OK so i installed almost every ROM on there and here is what i found.
TOP.

Your battery charges in 45mins? Does anybody elses battery charge in 45mins? I never heard of that before...

On AOKP I enabled fast charge once, if you don't use it at all while it's on the charger I think it'll charge in 45 mins.
EDIT: here's a screenie from AOKP with fast charge enabled

Hmm perhaps I need to have didhiy do the kernel fix. There's a fix on the nexus s since people had the same problem. So far, I've only seen you and another person on the epic having that issue, which is odd. Talk to him though, since he fixed it somehow. His name is popssracer.

In my personal experiences, the newest Cut & Paste ROM has AMAZING battery life. I can get over a day easily at home all day with no charge, and maybe 15-24 hours out in the world (I'm a professional touring musician, so there's times where I have NO charging source at all).
What I noticed also has equal or better battery life to TouchWiz are MIUI ROMs. If you can manage your power usage and turn off data services when you aren't using them, I could EASILY get days out of battery on 2.1.6.

I would say if you know how to manager your data when you aren't using it EVERY rom can get great battery life... even cm10...

[Q] Disappointing Battery Life

I got a Nexus 4 yesterday, and so far it has been excellent. Really fast and has all the features I want. The battery life is pretty poor though. I am at 28% with a screen on time of only about 2 hours. The total time is about 8 hours. I haven't been using it a lot. The main thing consuming battery seems to be Nova Launcher for some reason. I have it on my Nexus 7 and it doesn't decrease battery life at all, but it seems to use a lot more on here. It was at 24% according to GSam Battery Monitor.
I just followed a bunch of instructions for increasing battery life from various websites so I will see how it goes. I now have all the Google syncing disabled, location services off and brightness on auto.
Is there anything I should be doing? Why is Nova Launcher's usage so high?
Thanks,
EDIT: Could it be the widgets I am using? I have two Gmail inbox widgets, the messaging widget and the circle battery widget.

Same here though I'm not sure its nova, my battery got as bad as yours when i rooted to stock.

it could, or any other apps you have working in the background. it can also be how you use the device. but before you assume anything about your battery life, give it 3-4 battery cycles before it normalizes.

Alright. I have minor OCD kind of thing so I always close the active apps through the task manager as soon as I exit them. I'll give it a few more days and then pursue the issue further.

im ocd about that too, lol. the back button to kill is one of my favorite custom rom features. also, autostarts and greenify are both great apps to make sure that you have mich less ctap opening in the background. anyways, im a heavy user normally, battery life on the nexus 4 id never call bad. usually i get 3.5-5.5 hours screen on time, depending on use. but then again, i use a custom kernel thats optimized for performance and battery. but, stock rom/kernel isnt bad on battery.

I too Force Close all the social networking apps before sleeping and turn wifi off. And i daily get around 4 hrs of OST. Will attach pics later to show. So to get 4 hrs OST you need really need to have a custom kernel. Just optimize your usage and you are fine with the stock kernel.
Phone is totally stock. Not rooted. And i got 6 pages on Apps installed.
I even used to clear RAM every now and then but I just stopped doing it as I couldn't find it doing anything better.

The battery life is much better now. Yesterday when I got back from school it was at 40% or so, and today it was at 68%.

Gets better after a few battery cycles. My battery life was average, so I rooted and with matr1x kernel it's snappier and better battery.

i'm stock and my battery life was shockingly bad on the default settings until yesterday when i tried some fixes and they have made things much better.
looking at my N4 right now, i'm still on 58% after 22 hours. that's after several voice calls, some browsing & reading emails, GPS navigation using Maps, a couple of skype video calls, wake-up alarms etc.
basic fixes as follows:
- screen brightness right down to maybe 10-15%
- data off when not being used, ditto location services
- NFC and BT off.
- i've left wifi on as it doesn't seem to take much battery if it's not being used.
that's all! after charging last night, i woke after 6 hours or so and was amazed to see it had dropped only 1-2%, so apparently nothing is waking it from sleep.

One thing that really improved my battery life (when I had a Nexus 4) and something I tell to anybody with poor battery life, is to go into maps, go to settings, location settings, and uncheck "report from this device". If you've got the app "wakelock detector" just watch the wakelocks from maps almost entirely disappear. It nearly doubled my battery life at the time.

Hey thx man that didn't work but it did start me down the path to fix my problem.
I found out it had something to do with my GPS options its in settings and location access WiFi and GPS location options i checked it off and now i am getting 1 hour screen on time for every %10 if you do the math i have about 8hours of screen on time! I also have setcpu app which is giving me about 48hours of standby time, i will upload some screens after a bit more testing.

My battery life is brill and i never turn owt off or force anything to close, it is only bad when i play a 3d game or something but what do you expect. over night it only drops about 1% every 4 hours which is a bit bonkers.

Lol, so whats a custom kernel? cuzz i think I don't hav one because i hav rooted stock rom. sorry not to change subject
Sent from my Nexus 4 using xda app-developers app

first day of full use in my nexus 4 I got 5 hours of screen on time. stock rom and kernel, just rooted. I think it's pretty decent.
just do what people say, disable location useless stuff and monitor your wake locks.

If you would like to risk such things as unlocking bootloader, rooting, installing custom ROM and kernel, then it'd be easier for you.
Personally, I've found codefireX ROM and faux123 kernel to be battery friendly and very responsive, but of course you've got to be a bit fixed on such things as playing with your devices and getting fun from it to do that

another update:
after 20m browsing/ emails this morning and a couple of calls, i'm down to:
2d 9h 18m and 11%

disable auto brightness
