So basically just answer the poll based on a normal day of usage...
I'm curious as to how other people's nexus ones are doing in terms of battery life. I can practically watch the battery % drop. It lasts about 15-16 hrs, but thats even with being careful (enabling airplane mode in areas with no reception, disabling GPS some places, using only 2g at times). Heck, today, I lost 25% over 2.5 hrs, I was listening to music for about an hour, and was surfing the web for a little bit as well.
Yeah I can literally watch my battery drop as well. It's the always on data connection. One day turn off cellular data for the whole day just as a test, and see how much longer your battery will last. It's such a huge difference you could prob go 2 full days easily.

36 hours actually, that's what I got when I turned off background data,wifi, location services, chat, messengers, and screen brightness last fm syncing.but then its just a phone...and boring. Id rather use it to its full potential and charge it up when it needs petted like a puppy.
On average with normal use I go about 12 to 19 hours.
With data on, losing about 1.5% an hour in standby, with syncing and all. Math says if I don't touch it, it can stay synced 70 hours till discharged (assuming no phone calls and no SMS). Tried once, stopped after 48 hours with ~40% remaining.
Sorry, but this poll is useless.. Smart Phones are not dumbphones, you can't stamp a "runs this long" label on it. Everyone has a different configuration, different things set up, different accounts/number of accounts, different data moving on those accounts, higher/lower/no sync/notifications on social media, etc...
What you're going to get is this: People who play 3D games at high brightness for 3-4 hours and kill the battery. And people who have everything disabled and never use the phone and it lasts 2-3 days. You might get some in between, but the two above are the most likely to respond because it's "exceptional".
So I'm not completely OT and just complaining, I have online IMAP with K9, weather, Google cal etc syncing, randomly use it during the day, not much phone calls but checking the market etc... I average 2.5-3.5%/hr.
This holidays when I was abroad (no cell data) I found myself at night with the Nexus being at 65 - 70% battery after some GPS positioning (not navigation) for offline maps (rMaps FTW), some snapshots, about half an hour wifi and a pair of sms and one phone call. So yes, blame the always-on cellular data.
My method
This is what I do to maintain superior battery life:
1. I run CM 6 RC3 (I've found good battery life on this.)
2. I under clock the cpu (245-384) while the screen is off. This is a huge battery saver.
3. I turn off wi-fi (I found when I accidentally leave it on, I do loose a significant amount of battery when compared to when it is off, as it searches for networks.)
Thats really about it... My battery lasts the entire day and more (just by a little), with moderate usage. I do know, though, with heavy usage, the phone won't last as long.

my sentiments exactly!!!
I could, and I have made it last almost 45 hours with steady SMS usage.
I'd stick it in my locker, disable all activity (background, 3g, etc.), and when I took it out, I'd let it check my gmail and sms. Make my replies, and stick it back in my locker, pocket, or on my desk.
My main connection with family and friends is via SMS, so it's pretty easy to go the entire day with no internet use.
I'm running Enoms latest and I'm getting great battery life. Been 18 hours and I'm still at 52% with moderate usage. Not a lot of phone calls but plenty of texting, twitter updates and browsing through Google Reader. I have everything set to sync every half hour or less, GPS is on all the time and I have my screen set to auto brightness.
I just make sure to calibrate my battery when I flash a completely new ROM or when I notice my battery life getting worse. With Enom's ROMs I've never had bad battery life that couldn't be fixed with a calibration.

6:30am-11:30pm (17hrs): full brightness, WiFi on the whole time, Bluetooth on the whole time, gps the whole time (location services for about an hour), a few hours of talk, few hours of mp3, hour or so of Pandora, few hours of web browsing, gchat all day long,Twitter all day, taking some pics and video, and sync with two Google accounts and one Facebook. Percentage left at the end of the day... 30%!!!!!!!!
im in the same boat as ywindlass
im running cm6 with setcpu set to underclock while the screen is off. I also have it set to underclock once my battery level gets to 40%. I went from 12 hours per day with light to moderate use to almost 24 hours.
Yeah, CM6-RC3 with setCPU making the CPU underclock when the screen is off is the way to go. I've been able to listen to music for at least 6 hours a day and still be at 50% battery life by the time I go home.
About 16 hours on stock FroYo with 3G on, some music, lot of surfing, RSS feeds...

How long does it last?
How often do you use it?
Mine: 30hours or so using it once every 2 hours or so.
24-26 hours with no 3g wifi only 3 times a day for less than 5 min at a time to update weather no gps usage no bluetooth my backlight set to turn of after 10 sec and a total of less than an hour of phone calls per day. so i charge my phone alot
in general, i have no idea. but i do know i used my phone last ngiht watching youtube vids over wifi with no call, med screen brightness and it lasted about 4-5 hours. I don't think that's very good! lol
I lose about 10% listening to music for 45 minutes.
think I can get 24+ hours with maybe 20 minutes talk time over 3g maybe?/ not that graet anyways, whatever it is
I'm a heavy user. My brightness is all the way up. Screen stays on for 5 minutes. I turn wifi on at home to use the real internet. I talk for about 30-60 mins a day. I use 3G data when I'm not talking. I watch videos when Im not on the internet. I have a 2800mah battery. My phone requires charging after 8-12 hours of use. I just recently learned that half of my battery power resides in the last 5% on the battery meter.
It depends what you are doing. Seriously. WHen I first got it, I thought it was gonna die before the day ended.
On a typical day- 5-10minutes of phone, no 3g(i have edge,no 3g), 1 picture (just because I play around with the camera), pda about 10minutes, turning the unit off an on about once every hour or 2, internet maybe (5-10minutes), every 30minutes it checks email.
In 12+ hours I'm down to 85% battery. Not bad. I forgot to charge it once. By the time I charged it the following night (on for about 35+hrs) I still had about 40%.
It worked fine. But mind you stuff like 3g or always doing something that requires heavy power can and will drain the batteries.
With my constant usage, I only get around 5 hours max. I always carry 2 battery adapters with me.
dont know how long exact but i keep my screen at 100% brightness...3g is on but rarely use the connection...the occationaly wifi for updating weather and windows live email
i charge it everynight
I used to leave it on HSDPA to get mail every 10 mins, although make no phone call at all the battery only last a day and half. I was then disabled the HSDPA and 3G, just used GSM only, the battery extended at least to 4 days now, I still do get mail every 10 mins but only with GSM data. So if you find the battery do not last very long, you can try to do as what I did, disabled the high speed internet (HSDPA/3G) and leave it on GSM for a test in a day or 2. Hope this help everyone.
There are a few threads on this subject at the moment and I am sure the Moderators will thin them out but here is an observation I have found.
I travel quite a lot to different countries and use either my own SIM card or local ones to save money.
With different Networks and/or different operators, my battery consumtion changes radically.
I think it is a combination of Network polling (set by the local operator) and cell distribution (whether you phone is constantly searching for nearby towers) closer=quick fix father= constant polling that cause a problem.
This is over and above all our own device preferences and comms settings.
Hi Everybody,
I am using my HD2 since 2months and I share with you the general Idea that Battery life of 1-2 days is not enough for a device with the ambition to serve as phone as well.
I am using the device for professional activities: document sharing, webcalendars, emails on the go... but with an internet access not contiguous, since I only want my mobile to donwload mails when I
am not at home or in my office (were I have more professional stuffs
for that).
So, I installed the WMLongLife to Switch off communication interfaces whenever not used.
However, during last couple of weeks it happen to me to work prevalently at home and in my office, without the requirement to use the network from my HD2.
Accidentally I noticed that if I charge the HD2 and never use internet services (but only as a phone: 5-10 calls per day), the battery life magically goes from 1-2 days to 1 Week and more.
Is it normal? Maybe some device is not properly shut down after first use?
Now I charged my mobile on thrsday morning, and after 5 days of use I have still 42% left.
I wish to share your opinion, and to know if there is outside a better software than WMLongLife to preserve batteries when high speed connections, BT and Wifi are not used.
Thanks a lot
It's a phone with a massive screen, bluetooth, wifi, 3G and the list could go on...
I myself, is amazed that it can last a day.
Using it with constant 3G, bluetooth, GPS back and forth at least once a day, e-mails ticking in all the time, bluetooth headset and so forth...
The HD2 is like a small laptop...
- try getting a laptop run a full day on a battery the size of the HD2s.
1 week and more? Wow....
I fully charged the phone last night around 12AM, now after 13 hours most of which is standby, 1 hour of music, and maybe 30 minutes of browsing/playing with it its at 70% battery life. Is this normal?
I dont get 3G and I have wifi and bt off. Any other ideas to conserve battery?
The HD2 is as good, if not better than any other smartphone I've owned. I always recharge my phone overnight, so as long as the battery's good for a day I'm happy. Any bigger battery and the phone would need to be much fatter to accommodate it.
A week sounds pretty optimistic to me.

You could try and turn down the brightness of the screen for one...
I had mine on 100% for the first couple of days, but it just ate the battery like that. Then changed it to 70% (almost can't see the difference) when it's on battery, and that helped a lot!
Then you should perhaps try and download BsBTweaks or something like that, and activate the "power save" option...
Something to do with the SD card or something, not sure...!?
But to be honest, I think it's pretty decent.
13 hours of stand by, 1 hour of playing music and 30 minutes browsing/gaming - and still on 70%.
You have to remember, it's a very powerful device and as such it uses a lot of power!
Again I confirm,
charge this morning is still 25% left and yesterday I used internet connection for 15 minutes, then switch off devices and a soft reset to stop eventually pending drivers.
I do not use HD2 for listening music or playing films: only calls, contacts, synchronized agenda with gcalendar, emails, and internet.
Previously I noticed that after using even once the internet connection (without the soft reset), battery last at most 36 hours.
That is why I suspect some processes/services be pending in background and draining battery low.
Again I am not trying to demonstrate the life of my mobile is longer...
... Just noticed that there are some operational conditions that may prevent higher power drains and to understand if someone else has investigated the point.

I do the same!
Check email one or twice a day. 5/6 calls a day. Wmlong life on. Don't care about 3g... it's set to be in automatic. Some excel and word files. Some sms. It's incredible that such a powerful device can stand by so long!
Otherwise when I use it for work, wi-fi, bluetooth, gps and bla bla, the life of the battery is about 12 hours... but who cares?
9% this morning but still alive with phone interface working...
Do it exists for WM6.5 an extended taskmanager (AKA in the windows style) that can also reports for processes and spent CPU time?
I can barely go a full day and have to charge it at night.
Is anyone else getting really poor battery life? I have Wi-Fi on a lot but with screen off just so it automatically gets my push e-mails. Could this be the reason?
Can people post their typical battery life times with the D3 so far, to get a feel for how good this is (hoping its a bit better than the JUST one day maybe) of most phones nowadays)

Well, lets see. I have set the radio to CDMA mode only, purchased the extended battery (+400mAH extra) and have GPS turned ON, Brightness at 70%, and Sync is ON.
Yesterday, I got to 70% after 14 hours of being on battery. This was with light use. 1/2 hour phone call, a few text messages, etc.
Today, I've been on battery for ~8 hours, and I'm at 80%.
A few days ago. I went a solid 8 hours of heavy use: using maps/navigator for about 20 minutes, texting, watched a part of an HD movie for 10 minutes. Had WIFI turned ON. Took some pictures, recorded video in 1080p, etc. My percentage was at 30% before I connected the battery charger.
Edit: My prediction: Once you have fun with the phone, set it up, get use to it, and then switch to using it for daily stuff.. texting, some calls, check your bank, watch a youtube video, etc... you can most likely get this phone to last more than a day on battery power. For me, as long as it gets me from wake-up in the morning to bed at night on just battery power, it's good.
I've got the extended battery, first day usage running it dead got about 38 hours. About 6-7 hours on the phone, some internet and a bit of texting. Suprising thing is, display is only using about 2-3% of the battery usage. Most is Cell Standby and Phone idle, both about 30% each.
Weird, I was getting horrible battery life with the standard battery, about 8 hours even with CDMA only. I put in the extended and maybe got 9.5 hours.
Today at home I have been using it moderately with GPS, WiFi, and mobile radio on and am at 70% at nearly 10 hours of use on the extended battery. Crazy, don't know what changed, maybe my signal at work really sucks...
14 hours 32 mins on my first full drain. That was with some decent usage. I'm probably going to pick up an extended battery though
Pictures say it all. This is with moderate to light usage. Some phone calls, text messages, browsing facebook, etc.
Display Brightness is AUTO and I have the extended battery installed.

Ditto. I was at a little over 30 hours today and at 40% when I plugged my D3 in. This is pretty normal for light days.
Hmmm something must be wrong with mine. My girlfriend's and mine have been getting around 11-14 hours on a charge. A "charge" would be when it gets down to at least 15-20%.
I don't have any widgets running really, except that stupid Verizon data app sometimes seems to keep trying to access something when I'm on wifi.
Not too good for me here. Down to 70% with barely any usage after about 4 hours. 36% of that use is cell standby, and 32% is phone idle. 16% system and the rest is apps and all are under 5%.
I barely even use the phone itself and haven't even made or received a call since getting the D3. Today so far I've sent 4-5 texts and checked email a couple of times so for it to be down to 70% is crap.
I'm giving serious thought to returning it and sticking with my OG for a while longer. It was running CM7 with stock kernel and lasted considerably longer with heavy use.
Took off charger at 720am and at 942 its at 80% no good, made two 2 min calls and had some txt and iys already draining, I don't have really anything syncing and im on cdma
Sent from my DROID3 using XDA App
Does everyone do the sync every X minutes or on push? I'm using push and that's probably what's draining the **** out of my battery.
For everyone having trouble with their battery: Have you changed your mobile network to "CDMA Only"?
If you haven't done such a thing, here is how to do it:
- At your home screen, Press you Menu Softkey and choose "Settings"
- Then choose "Wireless & Networks" at the top of the menu
- Select "Mobile Networks" at the bottom of that menu
- Choose "Network Mode" and select "CDMA Only"
If your settings were set to Global, then the system would be going between CDMA and GSM every time you signal was weak or it was trying to acquire a signal. By selecting CDMA only (Verizon's Home Network) Then you are telling your phone you are in the United States and to stop looking for other types of networks. This should greatly improve battery life, as it did for me.

Awesome, I'll try to remember to report back here my results.
I've done the CDMA only with HOME only selected.
6 hours and 40 mins since taking off charger, and down to 50%. About the same as yesterday.
38% of it cell standby,
34% phone idle,
18% android system,
6% display,
4% android os and
2% maps is the whole list of my usage since then.
It's a bit early to tell, but yesterday I decided maybe switching to CDMA only was meaningless while the SIM card was still installed. It's only been off the charger for a bit over an hour but I'm still at 100%. Typically it's been dropping about 10% an hour or so. Will update after a few more hours of use.
My battery life has been sucking. I am around 50 percent after a days use at work. With my Droid Inc 1 it was around 75 percent. I have it in cdma mode.
Cell Standby 39%
Wifi- 29%
Phone Idle- 26%
Display 4%
Android Os 2%
Android System 2%
Doesnt make sense. The Inc was rooted too running CM 7. Cant make that big of a difference.

After 6 hours I was only down to 70%. Typically I would be at 50 or even hitting 40 so there seems to be some improvement. I also noticed that despite having set it to CDMA only, after pulling the sim card, it was set back to global.
I have only had the D3 for a few days, and so far I can get a full day out of the battery. I listen to music via bluetooth FIPO all day (+9 hours) and I'm generally around 20% when I get home. However, recently the Social Location app has been going nuts. See attached...

So you've seen an improvement in battery life after taking out the sim card? Has your cell standby percentage decreased?
With my display on auto and moderate texting. Ill usually last from 10AM in the morning to like 11pm and still have like 30% left.
I know there's a million posts about battery life sucks on the LG Thrill.
At first, I agreed.
But now I've had my Thrill just over 2 weeks. And it seems to last longer.
Not sure if it just needed time to break-in or what.
But I use my phone to sync with my company exchange server and sync contacts, calendar, emails (with about 150 emails a day). I also sync a personal email account, use Twitter, FB, News, Stocks, and Weather widgets with regular updates. (I rarely make phone calls)
It's about 12 hours unplugged now and the battery still shows full. I think 2 weeks ago it would have been near half.
I thought I'd throw this comment out there for anyone else that experienced poor battery life. Maybe give it two weeks and see if it gets better.
If your battery shows 100% after 12hours of use, I would think there's something wrong with the actual battery indicator software or whatnot.
Personally, using it very lightly with Superpower throttling down the CPU + shutting down wifi + data after 30s, the battery drops to 70% after 3hours of use. I would listen to some music for about 10-15mn in that 3h period, maybe browse xda for 5mn total.
I had the phone for about 10days now...

Something isnt right there... signal issues maybe? i checked mine earlier and was at 73% after 12%
Sent from my SAMSUNG-SGH-I997 using XDA App
Maybe the poster meant that the battery icon itself showed full because it's still got a decent charge despite it not being at 100%.
I actually noticed the battery life thing as well the longer I have had the device the better the battery life has gotten. I actually got around 20 hrs. on a full battery charge before I hit 15% so I think a Lot has to due with the way you use the phone. If your a media freak (Streaming Music, Bluetooth Headphones, Wi-Fi, Data always on, etc) than yea your battery will drain quite fast. I usually have bluetooth turned Off, Wi-Fi Turned Off when not near wi-fi that I access because Wi-Fi will constantly look for a signal which in turn drains the hell out of your battery, and Data turned off considering half the apps out there like to access data (In bed with ATT anyone) and I only have 200mb of data per month plus it saves on battery life.
I've owned the Samsung Focus S now for 12 days. I came from an android bionic. I have owned Windows Phones before, the Venue Pro and the Hd7. But this is my first Samsung.
For the first few days, the battery life was fine, a full day. But this past week I find my self hard pressed to reach a full work day. I don't play music during the day nor do I have many, if any calls. Mostly SMS and internet.
I've turned off as many background tasks as acceptable, limited the number of live tiles, set brightness to auto, and check email off of push. Yet this morning I reached 20% in about 8 hours.
In addition, I find the time to charge is extremely long. It might take 4-6 hours to fully charge from 80%.
Is this normal for a Samsung?? My other windows phones, and my bionic certainly do no present the same battery problems as this one does.
Thoughts, or is this usual?
Do you have wi-fi turned on? This is a real battery burner...
My Focus S usually goes through about a day and a half before I need to recharge. That's with a few phone calls, some messages, a bit of wi-fi browsing at night, etc. Email only gets checked every hour but it's on 3 different accounts.

while I'm home WiFi is on. Away from home its off. This is normal behavior for all my phones. All of them last at least 18-24 hrs, under the same condition.
Took it back to art. They said , lets try a different battery. I'm willing to try it for now.
I just wanted to add to this as I seem to be experiencing a similar issue.
I purchased my phone at the end of Dec, it's been great.
Now, since around a week ago I've been having issues. I used to get roughly 2 days use per charge and it used to charge quickly.
Now, the phone runs hot, the battery drains in 6 hours or less, and it takes many hours to recharge.
I turned off the one app running in the background. I turned off wi-fi. It doesn't seem to help. The battery itself doesn't seem to be too hot, but it's hard to judge.

I did a factory reset, and got a new battery. I then reinstalled less than half of my existing apps. In addition I've set my display brightness to medium.
Battery life has doubled, and the charging is much quicker.
Read an article yesterday about ads in free apps eating about 35% more battery. Who knows.
Even if they're running in the background? My Focus S takes a lot of time to charge and decharges so fast. 35% is no joke.

I'm also having some kind of battery issue, I have 2 batteries and they are both 100% charged but by the end of the day one is completely dead and the other is about 20%. I use my phone a lot for music and browsing over 4g and WiFi, but I charge by battery to 100% then go to the battery saver setting and at 100% it says time remaining about 5 hours. An when I turn on battery saver it says about 6 hours. On a full charge this seems crazy. Also with the homebrew battery monitor app. It says my phone is using over 4000mV. With screen set to low and in airplane mode. This is wierd.

4000mV? I assume you mean mA? not mV? 4000mV is only 4V which is about right, your voltage shouldn't change much, perhaps +-10% tops
if you do in fact mean Amps...
4000mA is 4A an hour, your battery would be dead in about 20 min at that rate and probably in fire as well
So, lets look at this in a different way,
2 batteries, that's about 3.3Ah max, you only had about 20% left in one which is approx 330mA so lets call it an even 3A of juice burned during your day.
An Average long day at work 12 hours
that's 250mAh current draw every single hour of that 12 hour day.
250 is quite high, but normal with the screen on and high brightness an wifi, however that isn't normal if you are normal and don't sit at your phone each hour for an hour for a whole day.
Things that can send your phone off on a amp burning spree? most common one is the backlight, set it to auto, and have a dark /black theme, AMOLED is the opposite to normal LCD screens where having a white background was best,
Next up is your signal strength, low 3G signal will eat your battery (4G is worse but thankfully we don't have that)
keep battery saving on all the time, it only kicks in when it needs to but I have seen dramatic differences having it turned off even with a full battery, im not sure what it changes when its not down to low battery but it does something.
background tasks can play a part but are minimal on WP.
I have 3 accounts on push sync, wifi and Bluetooth always on (but not always connected), I use it a lot during the day including several phone calls and web browsing, I start work at 8am, finish at 7 or 8 PM and im still sitting with 50% battery...
that works out at an average of just under 70mAh. that's about the normal level id expect, its double that if I turn battery saver off (even though it wont kick in until the last hour of the day)
oh I can make it go quicker when I show off the full capability's of our screens too
