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.

How do u check wake time?

I agree, but it want a heavy day. When I finally did have 14% left and used tv flash battery seasoned super fast. I forgot, I'm using juice defender too

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.

You should be able to get what you're looking for from the Spare Parts app.

According to my calculation thats is 69min of display usage.

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.

Here you go! Most of has data plan and always connected to 3G, sync contacts with FB, google etc, email client, weather widget, FB feeds, stocks, news blah blah blah...I get 16-18 hours max with all this running and moderate use.

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 noticed this. Usually the screen uses like 80% of the power after I used the phone for 5 minutes. This is after a night of my phone doing nothing and me playing around with it for 10 minutes or so. The phone idle and cell standby are really really high for some reason.
I did a reset of my battery stats but this didn't do anything.
When I was running stock sense with 2.2 it never gave me this result. Those two were always maybe around 2 or 3% or so so after a full day of use. It's weird.
Anyone else dealing with this?
Sent from my HTC Vision using XDA App

5 to ten minutes isn't really an accurate capture, have you given it a full day and then checked the stats? After five minutes it completely stands to reason that in that five minutes the display used 80% of the overall draw that happened during that span, does that make sense?

Same thing here. Used my phone for the whole day and the Mobile Standby used up like 40% of the battery. Mind you, there was a trip today so i used it for pretty much anything from playing games to downloading market apps and listening to music.
With the stock 2.2.1 Sense my display used up 80-90% of the battery all the time.

^Exactly. It makes much more sense that the display uses the most energy by far.
Half a day later.
Still seems weird to me.

It doesn't make sense at all. This is after almost a full day of usage. I've been calling, surfing and playing games on my phone.

Battery almost empty stats.
Sent from my HTC Vision using XDA App

I kinda figured it out. I just switched to use only 2G networks and now Mobile standby uses only ~35% of the battery. That's still too high, though.
Sent from my HTC Vision using XDA App

I'm gonna try that on my next charge. 30% is still very high though, it should be less than 5% or so I think.
Sent from my HTC Vision using XDA App

Can the radio affect the battery usage? If so, then shouldn't flashing some other one yield different results?

I have similar issues with cell standby being unusually high. My phone battery only drains poorly in one location (work) however. It will go from 98% to 15% by about lunch time even though I haven't used it. Disabling cellular data and wifi does nothing to improve it. Only airplane mode seems to stop this behavior. I have wiped battery stats and conditioned the battery and am at a loss on how else to troubleshoot this problem.

Removing WIFI calling and GanOptimizer using TI Backup has improved my battery noticeably thus far. Will need to further test over the next day to see if this was the cause of my battery drain. Here is the post I found concerning these two apps. It seems GanOptimizer puts WIFI in high performance mode. This happens when not using WIFI Calling (think you had to have used it once and then turned it off). My thoughts are that it causes WIFI to not sleep (ignoring the policy in the process) and leads to excessive battery drain as WIFI is basically running full power constantly.

i think how it work for the rightway?

Hmm... I dunno. There seems to be something weird going on with the reporting itself. This is after another day of use. I used navigation for maybe 3 minutes or so. When I look at the detailled view of that, it shows that it didn't keep the gps on or anything. It just doesn't make sense at all. I did many other things as well. Calling, texting, browsing, youtube etc. None of that is in that list.
A lot of things just don't show up in the list for some reason. Notice the display isn't even in there?
This is a fresh install that's 3 days old or so and. I don't have battery management apps or app killers installed.
Sent from my HTC Vision using XDA App

Well so much for an improvement. Came to work with battery @ 96% and two hours later it was at 69%. Android System now is apparently consuming the most with Cell Standby a close second. Think it is time for a phone wipe and slow installation of apps one by one to find out what is causing such excessive drain.

Well it seems like the error is in the reporting itself. The stats don't make sense at all, but my battery life is a lot better than when I was running stock sense.
On a side note, oh what a happy day today!
Sent from my HTC Vision using XDA App

I've been noticing the same odd battery usage on cm7.0.3. the past few days, getting 32% for cell standby and 25% phone idle :S. I've never really had usage this high for any rom except cm7, usually its my display around 80%.
I'm still getting average battery life (~18hrs on a charge) but nothing like the amazing battery life with rmk's g-lite 1.0.2.

1 Day 10 Hrs (34 hrs) Battery Life

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

battery life

Just thought I'd give a quick review of Cyanogen Mod 7 battery life and performance.
Standby battery drain of about 1.5%/hr with 3G, backround data on, auto-sync on, wifi on, GPS on.
I've never obtained such great battery life on any stock rom or stock-modified rom (I've tried a few different ones over the last year or so)
The performance is also much better than any of the stock-based roms (no lags).

No need to create new topic for that information.

fan/zombie boys everywhere
aple has ones so why not android ;]

Which nightly are you using? Which kernel?

After a night my Galaxy S is always dead. I solved the problem disabling 3g connection and sync. Stock rom 2.3.3 and semaphore kernel.

Sorry to say but useless thread. Just keep the damn charger always near you and battery life wont matter.
Btw did cyanogen pay you for posting this?or........

haha I had the same thought

I used to always hear about CM7 having god-awful battery life. I don't know if people were lying or if they fixed some major bugs, but I certainly have no complaints about my phone's battery life (running CM7, of course). I get through way more than a day.

That's my current battery stats. Haven't used the phone too much the last little while, but getting over 24 hours is not uncommon—I actually very rarely see my phone last for under 24 hours, and that's usually because of 5+ hours of screen on time. For that battery, I'd say about 75 texts, 30 minutes of phone calls, and about 30-60 minutes of web browsing. Fairly light use, but nevertheless, the battery life on CM7 is nothing to complain about.
EDIT: Looks like something was causing a wakelock the last ~6-8 hours while I was asleep, causing my phone not to deep sleep. If that hadn't of happened, it would still have quite a bit more battery (when I went to bed it was 44%, so it shouldn't have dropped to 27%—it should have dropped to ~40%). This just proves my point even more: battery life on CM7 is not bad at all.

seriusly?
do you see any battery change in that period compared to one earlier ))
when it was awake on your funny screenshot it was discharging with the same when the phone was not awake acordding to that stats so no impact registered

Thanks to share that information...

Best battery life that I've seen, using cm7.1 stable.
Currently at 2 days 1hr 15 mins with 14% remaining.
Wipes the floor with friends phones on stock roms charging every night. I only switched toCM7 after darkyrom barely lasting 12 hours at times

This sounds fantastic, Cm7.1 is my next choice, on XXJVT battery life is only 12h

thats using juicedefender to activate the data connection when screen turns on, emails still push to phone straight away with gmail so it is fine for me.
WIFI seems to drain the battery a bit quicker but not enough for me to bother flashing different kernels

I saw someone who did 2 WEEKS without charging. Normal using with black wallpaper on 2g network.

seems to be even better on ics... the best i had was ~2% per 8 hours...

3G + WiFi + email max 1 day
