How good is your battery life?

How good of battery life is everyone getting on their Fascinate? I've never had any trouble making a full day on it, and I think it actually got improved battery life since I installed the DI01 update a couple days ago. My phone has currently been unplugged for about 15:40, and with relatively light usage (no phone calls, reading a bit of news, checked the weather couple times, etc.), is only down to 71%. I'm not even gonna bother plugging it in tonight, and see if I can get through tomorrow with it.

i effen love this battery life. couldnt be any better
with continuously heavy usage i make it through the day, usally at least 2-4 hours of voice calls and 45min to 1hr with browser, 30min music, long enough to get the job done while looking at porn.(u know porn is for android LOLZ) ne way for real, another 30 min looking at droid-life,engadget,phandroid, and xda, and the rest on xda, its great

I get around 32 hours with moderate usage

I took 8.5 hours of streaming Pandora over 3g to get my battery down to 15% from a near full charge at work the other day.

I'm now at 1 day, 5 hours, and 47 minutes unplugged, and with light usage, am at 52%. w00t!

I'm averaging about 12 hours off the plug before I need to find a power source again. This is 4 hours better than my old Moto Droid 1 so I'm definitely not complaining. I spend a LOT of time on the Remote VNC app logging into computers around where I work, and that tends to drain the battery fairly quickly. I can easily make it through the day on my days off at work.

Yeah I get very solid battery life with my fascinate. Usually down to 40% after a full day which is constantly checking and replying to emails, moderate texting, maybe 45min of web browsing, 30 min of streaming radio, and an hour of playing Abduction 2 .

Im pleased as well. Usage varies. I tell people the battery is good for about 5-6 hours of constant non-stop use. Screen lit, downloading something via WiFi or 3G, apps, games, camera, emails, texts, GPS/Nav, whatever. Constant heavy use = 5-6hours. So if you are like me and average maybe 20minutes per hour of actually using it, an 12-14 hour day is a piece of cake. If you only average using it heavy duty 10 minutes per hour than absolutely you can probably get away with charging every other day.

22h 47m Since unplugged. Battery now at 26%. I keep GPS and Autosync off until I need them. Also installed an app called Battery Boost that helps manage battery draining stuff you can't keep up with. I think it helps and was free.

wow you guys are getting really long batt life. I moderately use my phone and I always get around 13-15 hours. I don't play games / listen to music, I turn off everything except GPS and have screen at lowest brightness. The only time I hit 24 hours is when I installed juice defender.

little over 16 hours; quite pleased
I am not using juice defender and I am getting a little over 16 hours with moderate usage.
From 5am to 8pm it lasts.. on 3g and at 8pm I get home and switch to wifi.. which is about 30% at 8pm.
I found that disabling that last option in the display settings really helped me.
I also am not using any task killers or (again) JuiceDefender or GPS or BT, just 3g cellular service for most of the day.
I am rooted and have the lagfix applied via the original dirrk method.

Battery Life
The first day I got the phone I thought the battery was crap. But I did do a TON of stuff on it. (Rooted, Lagfix, a zillion installs)
Day 2 with the phone I was at school and used it quite frequently from 7 AM and worked until 10 PM. At school everyone had to see it and it was in use almost all day. It finally died around 10:15.
Over all I am pleased with the battery life and I am sure after I get to a norm with having everything set the way I want it will last a lot longer.....

I've been streaming Pandora for about six hours. I've downloaded a bunch of apps/widgets and spent a lot of time customizing my phone, just playing around. Talked for about half an hour and I'm at about 50%.

Well, i think we can all agree that the battery life on the Fascinate is quite satisfactory. Oh, just a quick tip. With the AMOLED screen, black pixels are actually pixels that are turned off, so the more black you have on your screen, the less power it will draw, as more pixels are turned off. I set my xda app to the dark theme, mostly because I like it better, but it has the added benefit of saving battery life too. I plan on sticking with dark wallpapers and stuff.

Only had mine for a day so I can't really comment on the life of the battery, but one thing that does puzzle me is that the battery indicator in the upper right is full, but its only at 82% charged. Is this normal?

2nd day with this phone, first full day with it, so I've been testing the battery life. 2 1/2 hours of non stop usage since I woke up at 33% brightness. Calls, texts, testing the camera, playing games like NOVA, Asphalt, and Gem Miner, listening to music, and my battery is at 68%. I'm very impressed.
EDIT: Lasted from 1:19 to 11:33 yesterday before it finally died, and I seriously did not put it down all day. I'm very impressed with the battery life.

This is the usual for me. Using gps, music, lots of cellular data, wifi, etc.

Yesterday I went to MD for a wedding and took my phone off the charger at around 2pm. When I got back today around 4, I still had charge.
It's about average I guess, but I think I had better battery service when I uninstalled the verizon visual voicemail stuff. The VVM service seems to have an impact. I assume it monitors the voicemail server and downloads voicemails when they come in.

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.

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'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.

Don't think you get great battery life when you don't use it much.

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.

3 days, 3 Hours, 24 mins of Battery life on my Epic

I hope this is actually true for me as well. I will upgrade once its fully stable.

I tried the EE03 ROM for about 2 days and I went back to my EC05 SRF 1.1.1 because I'm running my 2800mAh Yoobao which I can average 2 days on using the full 100mhz - 1400mhz range of the Genocide Kernel....with EC05....the two days I ran EE03 I couldn't make it 15 hours...smh I don't know if I'm missing something but can I get a pointer to get the full capacity I know my extended battery can give me running EE03?

Data was on the entire time. Its really not that hard to do. Freeze DRM apks. Stop unneeded junk from starting up and launching upon connectivity changes and the like through autostarts. If you REALLY wanted to save data, turn data off at night while you are sleeping by long holding the power button and selecting turn data off. Stop syncing with facebook every 15 minutes. I don't sync or use facebook at all, maybe that is the magic bean. Don't have 30 widgets constantly running. Don't overclock. Brightness set low. Very simple things.
Edit: Also, properly calibrate your phone and battery. Turn off auto rotation and haptic feedback and things like that.

What was your screen on time?

Have haptic off and drm killed. I will check facebook. What startup killer do you use

I think it's crazy the differences of all "smart phone" battery life.
How can some people get 4 hours and others get days? I went through this with my EVO before exchanging it for my epic. Others have problems with their epic and none with the evo?
The hardware should all be the same so is it all androids fault?
They really need to fix this issue.

Which app was used to produce the graph in the first post? I don't think I've seen that one before.

There are a few reasons.
1) Some users just REALLY use the hell out of their phone. They have 4g enabled and are constantly taking calls or streaming music or browsing the internet or gaming on it.
2) Some users have no idea what they are doing. They enable 30 widgets that are constantly updating and pulling data. They have facebook and twitter syncing every 15 minutes. They have the brightness set from medium to high. There is nothing you can do to make a setup like this save battery life.
3) Some users KNOW what they are doing. They limit their widgets to necessary ones. They set the brightness to autobrightness or low. They lengthen the time between syncs for social media. They freeze the DRM files. They use something like autostarts to limit startup programs.
That is why battery life is all over the place. Also, people have completely different definitions of what "heavy use" or "light use" is. Add on top of all of this, that people are using different roms and kernels. Add on top of all of THAT, that some people undervolt their phones.

Which app was used to produce the graph in the first post? I don't think I've seen that one before.

That is the stock gingerbread meter.
Gingerbread is awesome like that. If you go to Settings>About Phone>Battery Use and then tap on the small graph up on top, it expands to create that full screen graph.

I have noticed a huge battery increase too. I have not changed any settings on my phone to try and improve it. I got use to my 12 - 16 hours of use moderately. The only difference I made was not installing Advanced Task Killer and relying only on the stock Task Manager. I got 1d 8h of battery life on OEM battery. I will post screen shot when I get to my computer.
