1 Day 10 Hrs (34 hrs) Battery Life - Epic 4G General

First things first: A BIG thank you to all of the devs still working on the Epic. This phone is not that old and I still think (because of the keyboard) it's a great phone that I'll enjoy for all of the 2 years I'll have with it. Fortunately, there are others who think this, too and put in the time and effort to make this already great phone better for FREE. I'm not a developer, but I do know it takes a lot of time/dedication to accomplish what they have. So thank you to all of the developers (present & past) for the Samsung Epic 4g
Hello, I'm a lurker none of you know but would like to share my results dealing with battery life on EH06
This is the best battery life I've ever gotten and I have no doubt that I could've reached 1 Day 12 Hrs (36 Hrs) of battery life. A day and a half, I guess I should've waited and let it run out, but my impatience got the best of me.
What I did was flash crawj's EH06 deodexed .tar
I flashed theduce102's (EH06) Copy & Paste ROM Stock Cyan v1.1
I then flashed deano0714's Sculpted v2
I was using the EH06 Modem
Auto-Sync was left on the entire time. Twitter/Facebook sync every 4 hours, contact sync left on.
Brightness left on "auto"
Wifi is left on always, at least until I was out of range.
Personally, I highly recommend juice defender. It'll turn off your data when the screen is not in use which saves a LOT of battery. Sure you could turn it on and off yourself but it's just much easier to use juice defender and have the data turned on for 30s/1min then left off for 30 minutes. 30 minutes is the max for the free version, but I still find it useful.
Take into consideration that I did NOT use my phone a lot.
My usage consisted of about 5 texts/hr, few downloaded apps/updates, few email checks, couple hours of listening to music, 20 minutes on Dolphin Browser HD.
If there's anything else you want to know about my setup, let me know and I'll update the OP.
The colors in the pics are inverted, most likely because of the screen cap app I used

I also got 35+ hrs on EH06 deodexed with the EH06 plus kernel. It was pretty amazing... Didn't take any screenshots though...

A year ago on Eclair it lasted 2.5 days. Complete stock, no root.

this is all nice but I've kinda never understood the point in having a smartphone if you're going to have data shut off the majority of the time. of course most battery life is demanded by data - I'm willing to bet I could get several days of battery life from any build if I put my phone into airplane mode all day but what's the point?

I feel the same way. I used to be obsessed with keeping my data off as much as possible. Then I realized....what's the point. The whole purpose of having a smartphone is to be connected all the time. I say keep your data on and use your device how its meant to be and enjoy it.

yes. plus where are these people that they can't access a wall socket or power cable for days at a time? I can get 14-16 hours with moderate usage by leaving everything turned on. then when I'm home where all those power sources are, I, you know, plug the damn thing in.

What's ridiculous is that these people never made or received a single phone call in 1 to 2 days. WTF? Why did you buy a phone? Go get yourself a Palm Pilot.

I hear ya. I usually get between 10-12 hrs of moderate to heavy use. If your that worried about it bring an extra battery with you. Shoot I carry or have quick access to an extra battery and a charging cable most places I go. I usually don't have to use it, but its there in case I need it.
@OP, were not trying to derail your achieving over a day of battery life, that's sweet that you can get that. I'm just questioning the usefulness of said achievment.

And screen on time....sorry OP but what was the screen on time. Maybe a little over an hour? I saw a lot of gaps on chart.
Having said all of that, that is still pretty good standby time for a GB leak. I've gotten 1 day plus 3 hrs with everything running before. But that's with srf 1.2 and with hardly any use...plus wifi.
From cellblock D

I like this post I had my phone shut off on my yesterday at 4pm and it was full at 8am when i took it off the charger. Didnt do much of anything it somehow jumped from 50 to 25 all by itself. Im on genocide 1.1 and srf 1.2

23 1/2 hours on single charge

I just got me Evo two days ago, and flashed DamageControl's rom. I don't live in a 4G area, so I have that shut off. I generally don't turn on WiFi or GPS unless I'm actually using them. I did have wifi on a few times yesterday, but for a total of no more than 45 minutes. I have three email accounts, two that update as soon as mail comes in, and one that checks every hour. My corporate and google contacts sync as well as both calendars. I have facebook syncing in the background as well.
I did a decent amount of emailing and some web browsing. Even with all that I went 23 hours and 36 minutes before the battery went red and it told me to charge it.
I was worried with all the horror stories I heard, but that was pretty incredible battery life for my average use of the phone.
Is your battery completely covered in the orange HTC wrapping or does it have spots on the back where you can see the silver underneath?
It looks like it's completely covered. Although I would say it's red not orange. I couldn't tell you which batch it came in as I got it off of Craigslist.

People have reported that battery is better than the ones that aren't completely covered.
I too have the all red wrapper battery, did a 8 hour charge with the phone off prior to this picture.

I did jack **** with mine and was able to squeeze out 28 hours
I usually average 2 days on a charge, usually at least 35 straight hours. Having a second backup battery gives me more than 3 full days.
I think most of the problem lies in how the phone charges the battery; usually it doesn't charge the battery to 100%, but it thinks it has. Some days I get 5 hours out of my phone and other's 12 to 15.
I've tried every tweak I can find and run fresh 1.0.1, too.
I think I'm going to have to buy that 2 batteries and charger for the HD2 on ebay for $10; anybody have that link?

Drocap2 works excellent
I am relatively certain the Evo battery has a break-in period. My first week owning the device I was running:
Voice
SMSPopup
Push Gmail
Push Exchange
3G on / WiFi off
Did some gaming, light browsing, lot of texting, moderate usage over the course of a day.
I got about 8 hours tops before the battery died. That was with the screen brightness at HTC's "medium" level.
Yesterday, I had the same running in the background, did the same things except I also read a bunch using the Kindle app, and used GPS a bit, and I was at 60% after 26 hours off the charger. No special "tricks" like task killers (ew!) or underclocking hacks or startup killers or anything.
Huh...I am not where near getting that much. About to start my fourth week with phone and still in the 12-14 hours.
Are you all doing the charging routine or just plugging in? If I just plug in I definitely only get to about 10pm. If I do the charging routine I can get still have about 30% by evening.
Was someone having issues with the battery life on the Evo??? Cause I'm not.

My Battery Life WOW! *Pic for Proof*

Using Myn's ROM with the Battery Tweak, I have FaceBook syncing and I have 2 gmail accounts syncing along with Weather every 3 hours, Facebook every 2 hours.
Nothing else as of now and using Itching Thumb App.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.
Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.
Barely used phone. Come on.
Display 4%? Is that possible?
I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.
wifi is on = low battery usage, atleast in my experience.
Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.
so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

I win. And after actually doing a full calibration of that, i got ~65 hours total
I was at 2 days 9 hrs with 19% battery life left before I plugged it in the other day.
That would be equiv to 57 hours with 81% drain.
If that was a straight linear drain and with a fully calibrated battery that would be an estimated 72ish hours of battery life.
I am running Onyx 4.2.
i got 4 days 8 hours 12 minutes. still running at 16%.
19% @ 21h 6m 44s since unplugged
but i don't remember if i rebooted or plugged in the usb somewhere along the way. either way, acceptable battery life, maybe slightly better than JI6
obsidian v4.2
edit: w/ stock kernel. i've heard the UCLF kernels have been having battery issues
Anyone can get 60 hours if you unplug, connect to wifi or turn off data and let your phone sit unused...these threads are pointless...
haha holy cow thats a long time with ur battery what do u guys not useur phone a lot???? =-O
Who has a longer battery life? Toyota Prius!
How can you compare battery life on a device that is being used differently from person to a person
Use System Panel statistic at least! I got -1% per 6 hours of sleep on Obsidian v4.2 and ~6 hours of constant usage.
So are you guys using eugene's kernels that give you actually ALL of the battery life by letting the battery die at 3v?

Exactly, even turn off wifi for more juice!!
Realistically, the best I have gotten was 24-25 hours (moderate use)
i actually use my phone normally, for me at least. and yes, i can still get 60 hours. i don't have a data plan, so i use wifi. I text throughout the day, but i'm not a "heavy" user so that's why my battery is higher.

played angry birds for 3 hours straight, still at 90%.
I hit a record.
Yesterday riding around I must have watched a few YouTube videos and surfed the web/used XDA app to read forums. Perhaps I sent a text or two. No phone calls, GPS, or WiFi, though...
2 hours 34 minutes (yes, that's kind of ironic numbering, but that's what it said) later it was at 27% battery life left.
I now have like 80% of the Apps I had installed before uninstalled, so I know it's not a software issue with something draining the battery.
Display was taking 77%. Samsung initially stated that the sAMOLED screens would not drain as much battery, I think that is likely the culprit for many of the battery woes. I will be sure to avoid this screen type in the future.
My HD2 has a much smaller battery, but with the same usage patterns it runs circles around this Vibrant. It's not even funny.
The Vibrant can maybe standby for a day and a half. I can use my HD2 casually but let it stand by a majority of the time and the battery lasts like half a week...
I think the Screen is the culprit, IMO, which would explain why people who turn off auto-brightness and fiddle with that see much better battery life. On the flip side, the issue is exacerbated because the Vibrant doesn't have an LED Notification light (like the HD2), so everytime you get a text instead of using an inexpensive LED notification light, it's flashing that screen on. That means even if you don't use the phone all that much, your standby uptime can still be deplorable compared to some other phones if you get a lot of phone calls or notifications which turn the screen on.

I'll believe that when I see it. In any case if I play a game that long on the phone (I never do, but IF), I'd be at a charger, anyways.
21 hours to 50% ON STOCK
I got 21 hours on 50% drain using the juice defender on the stock rom. Not bad i would say especially considering what I was getting before I took steps to conserve battery life.
As someone else already said, this is kinda pointless. Everyone is gonna use their phone's differently. With all the apps, configurations, etc, there are literally millions of different variables.
Something that I find puzzling... I see so many people upgrading to 2.2 only to get 6-12 hours battery life. Why in the world do people accept that? What is so great about 2.2 that people are willing to settle for having such piss poor batter life just so they can run 2.2 on their phone's? I don't get it at all. The best I could manage on 2.2 was 18 hours. That rom came off my phone so fast it wasn't even funny.
Anyway, with normal use (read: light to moderate) I get just about 3 days with my phone on 2.1 Bionix. I wouldn't be considered an average user though, as I don't have 3G in my country and my widgets only moderately access the web. What helped me immensely was disabling data when I don't need it. I mean, do you really need your phone checking your email, weather, facebook, etc, while you're fast asleep?
i can play pocket legends for 3 hours straight from 100% to 5%. think it's good but not enough.

I'm Getting Great Battery Life!

I installed OMGB-6 when it was released. Then flashed invisiblek #21 kernel and the new market. Since I last charged it, I've talked on it for about an hour, used the web-browser (Skyfire) fairly moderately, sent a few emails (Gmail), and spent a total of about an hour of GPS through the application WAZE. I'm left at 22% battery left after about 22 hours of use.
I've been fairly lazy with regards to changing the screen brightness, so it's been on about 50% brightness. I've left sync and gps on during the whole time.
I've been using Watchdog as a smart task manager. I have SetCPU installed, but I haven't used it at all.

True, I haven't been using it all that much. But compared to other ROM's I've used, this get much better battery. Everything else I've tried out got me a max of ~12 hours even on idle the whole time.
Definitely try to install the kernel. Can't hurt! Just make sure you always have a nandroid backup available.

50% Brightness?!?!?! Wow....battery life is not worth looking at a dull screen. 100% all the way for me...im using 1800mah from ChiChitech that I got for $20. Seems to help enough.
I'm also running a Gingerbread ROM (Evervolv a17) but can't tell what difference it's making on battery.

Hydra 1.13 overclock kernel, stock ROM, stock battery, auto-brightness. I'm currently at 20% battery after 2.5 days. Light usage over the weekend, but there is an hour and a half of talk time in there and a half hour of reading.
The trick to DI battery life is keeping the data network usage/standby under control. If you're trying to send/receive data with no signal, the phone will burn through its battery in 4 hours and I've used 20% in 15 minutes trying to book a flight on a low signal connection.
Realizing this took me a few months since I live in NYC and as such, go through a lot of signal shadows. Some days my phone would be at 50% battery after 12 hours, other times it'd be dead after 6. I now realize that the short days were caused by sync services trying to run when I was in a shadow. You can diagnose this for yourself by going to the cell standby section of the battery usage. If you're over 10% or so without a signal, you have this problem.
You can handle this manually by holding down the power (on the stock rom) and enabling/disabling mobile network. This is a pain in the ass.
I handle this with some simple Locale rules along with the Mobile Signal and Mobile Data plugins. The first is to shut off the data when there's no signal. The second is to shut off the data at work where I'm usually but not always on a wireless network. The third is to shut down the data during my normal sleep hours and airplane mode if I'm at home.
These easily got me to 36 hours so I grabbed an undervolt kernel, which gets me to 2 days of regular use. Daily I do about 15m of talk, 40m reading news/email on the subway, and another 30 mins browsing/messaging/misc. My monthly data use is ~350MB.
While it is likely true that the OP and others have good battery life under their specific use conditions, battery life in general on smart phones is mediocre to poor at best. I have friends with various different models of smartphone (including iphone) and across the board battery life is not good. The exception is blackberry, but I don't consider those competitive from a tech and feature standpoint. Obviously different people are going to have different opinions and experiences based on the various factors that influence battery longevity.
The solution is to stop worrying about it, get a spare or two or three and pop in a new battery when one dies. This imo is one of the best things about the Dinc and Android phones in general. Just my 2c.

The "all of the sudden" battery fix on ICS

I have been using my s2 only 1 day on GB so i cant really tell you was the battery life good or bad there, but i i have some news for ICS
stock ROM users.
I was actually really depressed by the ICS battery life (i upgraded from GB same day i bought brand new S2), battery life was terrible,
turning on/off syncing, mobile data, gps etc etc helped a bit, but not that much. i still couldent get full day out of it with moderate use.
Again, im on stock 4.0.3 atm.
And then, a miracle.
Let me say right away, i am aware that these types of batterys (i have stock one btw) dont react on this whole "fully discharge then recharge" thing, but i do think now Android ICS as a system does! Cuz it was exactly what i did-i said what the heck doesent hurt to try and i was playing games like crazy when battery was on 10 or less percent so it wld shut down. then, i connected charger and used as normal on charger until it was fully juiced. repeated 3-4 times and what do you know... i now get 50% OR MORE WITH THE SAME BATTERY!
I am not really sure what happend there. Did battery gauge reset? Did ICS "learned" my battery properly? I dont know. All i know is that i am now able to get trough whole day (i get up 7:00AM, go to sleep round 01:00) with only 1 full charge. I dont even bother turning off wifi sometimes when i go out and dont need it.
I have been also reading around the web that some people got the same result. No calibration trys,pulling battery etc etc...just let it go trough few cycles and let system/phone "calibrate by itself".
Not exactly sure if this is a solution, bug, feature or whatever. I just thought it was worth writing to you guys
cheers, loop
why dont u share some screenshots
np mate, but in evening or tomo morning when i come home
Well, you actually shortened your battery life span by draining your battery to nothing, you should probably google what happens when you drain lithium batteries, and how it affects capacity, and not just
dont react on this whole "fully discharge then recharge" thing

You probably did reset your fuel gauge as your phone had no power to hold the gage memory, but you could of saved yourself a lot of battery capacity, by using search and finding out how to reset the battery gauge on the Samsung galaxy s2. Hint* search extweaks and Siyah kernel.
Anyway at least other people who read this, hopefully learn and do it all the easiest and battery efficient way and not

Hope this helped, and for future reference do not drain lithium batteries, whether it is your phone, laptop, ps3 controller. Try not to get it under 50% for the best efficiency, but the more you drain it to minimum charge the faster it degrades.
Did you uninstall anything? Did you change any settings? Sounds to me like wakelocks that were removed more than ICS "learning" your battery.
Take it like this: i upgraded to ICS over GB and did full wipe. First day i installed lets say 20+ apps that i use. mostly utilities,few games.
In this period of "recovery" i only updated few apps, installed GTAIII and Flipboard.
Let me make this perfeclty clear as i stated in OP and as deniso wrote: i am aware of todays batterys and how do they work. i am not senior android user but i know my way around,so as i stated, i know i dident "FIX" the battery itself. But i still think the main problem here is not the battery itself,its how ICS uses it.
However this:

is just... funny. "try not to" ok i get it, but below 50% is when u need your phone the most, should i carry a portable generator with me? no offense.
Please, do not throw rocks at me. I am aware what i wrote, and i am aware that it doesent makes sense with todays batterys and smartphones.
however,i still do have my better battery life, whatever u say or dont say.
Ill make some screenies when i come home.
Ty all for your feedback.
I said TRY not to, I personally use my phone all day and my battery only gets down to about 75% -85% at the end of the day, so it takes nothing special for our phones, unless you do heavy gaming or movie watching all the time.
And what I said, which wasn't throwing rocks at you, is that you probably just reset your fuel gauge as there was a lack of power to the memory chip, and like I said in my first post, Search EXTWEAKS and Siyah kernel as they have that exact function in them which does not require you to drain your battery below critical values or at all.
hello again, just posting screenies that i promised

(its in croatian,but you can see what is important)
So as i said before. This is roughly really 50% MORE then what i was getting first few days on ICS. now, i dont know still if this is very good or average, but
it gets me trough day for sure. As u can see, i posted "screen on" time, cuz i was not getting even half of that before and i still have 34% left!
The day was filled with 5-6 emails, i watched 4 youtube videos, did cca 29 mins on surfing and cca 30-35mins in plants vs zombies. few sms, few calls.
So, im not playin smart here or anything, i just have more batter with whatever i did, and it makes me happy
Cheers
You getting more battery after 3 days could quite simply be due to the fact that you flashed new firmware and it always takes a few days for the kernel and modem to 'settle in'. You will never get a true indication of battery drain straight after flashing firmware.
And to the guy above who said he can use his phone the whole day and it never falls below 75%, wow!
I would love to know what firmware, kernel/modem combo you're using.
