i use WiFi @ home and work, 3G everywhere else.
my battery was over 50% before bed, woke up with am with 5% left.....
so 45% of my battery life was eaten up in 8 hours with NO use?
any thoughts?
Wifi seems to be a real battery eater on this device (along with GPS). I leave it switched off unless I'm actively using it, and have no problems with battery life (it would last >24 hours if I let it.. I charge overnight though).
As there's no 3G switch on the widget I don't ever switch that off so haven't seen what improvement that would give. Cell Standby is still the largest user of battery, so maybe it would.
Set wifi to sleep when screen turns off.
There's an option for that? Not seen that one..

I didn't know you could do that, however, i already have that option selected....after i found it in the menu.
i guess i'll just have to experiment and see if 3G saves me power over the weekend.
Yeah I am pretty sure that option is the default. It still definitely drains more power with the WiFi enabled than without, sleeping or not. Not sure vs 3g, I disable or enable both as I need them.
I thought Wifi drains very little power ... with my phone on airplane mode and wifi only, the battery lasts over 30 hours with Meebo on, push e-mail on, and e-mail sync every 15 min.
Likewise, I have gps/wifi/2g/screen widgets on my main home page.
This doesn't exactly apply to the OP, but there's a nice app called "Y5 - Battery" in the market that switches off the WiFi radio in areas that you usually don't use WiFi.
Also, you can see what's draining your battery if you go to Settings > About Phone > Battery Use. There's some cool graphs showing where all your battery went since the last charge. Maybe you have a program that's running in the background that's sucking up all your battery.
I have had some battery drain issues since I received my N1 3 days ago. I found that Android 2.1 has a nice battery log (/d/battery_log) which updates every 50 - 55 seconds. In doing some tests to see what was killing my battery I can tell you that it isn't WiFi.
I would say that when in use, 3G draws a bit more than WiFi when actively used, but when WiFi is just idle it seems better than when 3G is connected and not in use.
In case anyone cares...I am still isolating all of the battery drain issues, but one of the biggest I have eliminated by uninstalling seems to be from BeautifulWidgets. I found it hard to believe, but my testing seems pretty clear. I also have a decent draw whenever I'm in the car with Bluetooth sync going. I would have had a hard time confirming this without this battery log file.
Wifi is extremely power efficient on this device.
I use the device on at&t edge and have the wifi turned on all day. the battery drain with pus email i about 4%/hour.
I think the combination of wifi PLUS being on an HSDPA network is killing your battery.
pus email? sounds gross
A quick calculation gives me 2.4% an hour, and that's with sync on, Wifi off, 3G on and using the phone a bit (not so much today). That's consistent with what I see normally - if you never actually used the phone you could push 3 days out of it.. but of course there wouldn't be much point in having it switched on then so it drops to about a day after a bit of driving w/bluetooth on, streaming music, etc.
Of course it's not really productive to look at battery life as 'how long can I make this last' (although knowing I can theoretically push it to 3 days plus is going to be useful on holiday). You work out your average day.. say up at 8am, turn in at midnight, so that's 16 hours actual time that it's needed (assuming you charge overnight like most do) - then fiddle with the settings based on your own use so you hit that comfortably. I'm probably being overconservative right now.. I'm finishing the day with nearly 50% battery left & need to ramp it up a bit Maybe a few more games of Frozen Bubble..

I'd love to see someone get 12 days of standby!
The specs for mobile phones are always a bit of a fiction.. maybe you could do that if you put it in airplane mode and if you never activated the display at all...
I had a Sony Erricson that claimed 800 hours (over a month!) of Standby. Never got it over 2 days..
Would be interesting to see if anyone has managed 10 hours or even 7 hours of talk time... personally I doubt it.

Some phones in Airplane Mode when not used can do those kind of numbers though. My K800 lasted about 2 weeks in standby when running like above. Though that just proves how pointless such numbers are.
So when using wifi, is 3g auto turned off?

I would assume the data aspect is, but the 3G voice is still active, even with WiFi on.
Maybe my battery is not trained yet, but so far, on my 2-days old n1, battey lasts for 4 hours (mid. backlight, no wifi, very little use).
Still running stock rom and not planning on rooting.
What I noticed is that in my battery drain stats show Display contributing to 80% of total drain. That's with display being on mid setting... is that normal? What is yours (esepecially for people with stock roms)?
Are you playing with the phone a lot? Like is your display always on? 4hrs still seems extream to me, I am rooted and runninng a custom rom, but even when I wasnt I never managed to get through the battery that quickly, and I use the phone a lot
Here's what I do to get good battery... I only keep backlight on like the a ****as hair..lol barely unless outside...... widgets are cool n all, but if there constantly updating thats polling your battery, live wallpapers are cool, but a battery drainer, I also keep gps, locations and bluetooth off unless using them, wifi also.. also the background applications setting uses battery but if ya want updating widgets no way around that...
Also look in seetings about phone, battery use and see what's eating your battery, I use my phone hours at a time so my display is most my battery drain which is normal, everything else is like 7 percent or less, mostly 2 or 3 percent. ....
I think thats all I do, but you may keep stuff on like widgets and that unfortunately eats battery..
I am running everything in my Sig. I have had my N1 for about 2 months now right around that. After a 14 to 16hr day with some heavy to mild usage I am still over 50%, but then again I have 3g turned off and i am only on Edge all the time since i am always around WiFi. So i would tell you 4 hours is a bit extreme but hang in there it does get better. I remember being around 25% for the 1st few weeks until it got better. Other wise do what Temperbad said that is the best way to go. Only widget i am running that updates every hour is my Weather one. Turn the screen all the way down unless it other wise needs to be up. I am sure that is what is killing your battery. Mine is always on the lowest setting until i am outside.
Sadly I'm rooted, but I will state my percentage too.
Weirdly, my display usage is only 15% on Paul's Desire ROM. Honestly I dont see how this may be - but that is what it says. My brightness is quite high too..
Yeah, I'm well aware about widgets and battery drain regarding 3G and all that, I've had PDAs for quite a while.
For comparison, my old and ****ty TP2 would drain about 30-40% of its battery with same usage that would drain my N1 dry.
I do remember that LiIons get better in a week or so of usage, but I wanted to hear what you guys are getting. Would love to hear from someone who's just bought an N1 like me.
It's under full warranty, so I'm not worried too much. Just an inconvenience.

I have my display set to "Auto Brightness," have a display timeout of 1 minute, have my email get synced every hour, and also use a live wallpaper.
My display accounts for 63% of battery usage.
Auto brightness will use more battery than keeping it low. Cause its constantly checking light density through the sensor to give it the correct lighting...

I agree, but disabling that, disabling GPS, WiFi, turning off 3G, killing all widgets.. ok yeah my phone will last me 2 hours longer, but it's also boring as hell.
Might as well go pick up a simple nokia for $10 - battery will last for weeks, but what's the point..
Not saying your advise is bad, it's a good idea.. just that all these advices to turn everything off - what's the point of even having a PDA then..

I've read otherwise, though I don't think that Auto Brightness is the optimal battery saving setting.
Obviously it's a middle ground between max and low.
Here's a report of my usage today:
~Wifi and 3G both turned on the whole time
~30 mins of MP3s with head phones
~20 mins of 3G tethering over Bluetooth
~40 mins of apps usage (mostly the Browser and the Gallery)
~8 mins of talk time
one 1 min update through the bootloader
have gmail sync turned on, also twidroid syncs every 15 mins
The Battery use app shows:
54% Display (active 6% of the time)
16% Cell standby
14% Phone idle
4% Wifi (active 51.6% of the time)
4% Android System
Right now 14h26' since unplugged, still having 43% of the battery left. The battery meter says 12 more hours until 0%.
All things considered, the battery life is quite good on my N1.
Edit: forgot to mention, the display is set to the middle setting with the Power widget, no auto brightness

Wow... that's some serious battery life.
Ok, some questions..
1. screen brightness setting?
2. how long have u had that phone (battery) for? Did it improve over time?
3. Is it rooted/flashed or stock rom?
4. you got any syncing widgets running (RSS/twidroid)? Live wallpaper?
Thanks a bunch for your input!

Just one comment. I keep Wi-fi and GPS on all day because Wi-fi sleeps when the screen is off and only polls when the screen is on if you're not using it. GPS is only used when your location is required in an application. i dont know why people are always like "you have to turn these off to get good battery life" (Notice wi-fi is 2%)
also i've been running 8 hours with moderate to heavy use (internet, music, phone calls etc) and I'm @ 40%. The drain from 70% - 40% seems to go so slow compared to 100% - 70%.

Your right... about the updating widgets and wallpaper, they do make the phone funner.. but why need gps on when not using, or bluetooth, or wifi? Just simply turn them on when using...
So much going on with this phone I can say its good pretty decent battery....
Anyone know how to make my gmail sync every hour instead of instantly?
When I got my Nexus my battery was just as poor, but after using it for a couple of weeks I'm getting about 10 hours usage with medium brightness, WiFi, and gps.
So just give it some time and it should fix it itself.

Your phone or battery is defective. Call HTC for a replacement.
Hi Guys! and Gals..
Wondering hows your battery life?? Can you make it through a day Ok? I have a touch pro on Sprint and battery life stinks in the worse way.
Last time I checked, it went 13hrs until 31%.
I usually use it for around 90minutes continously reading or web browsing during my commute. There is also 4-5hrs (or more daily) during which I only get 1-2bars of receptions, so it drains battery faster. There was probably also a 30-40minute phone call using bluetooth.
I can go an 10-12 hour day with light use:
45 mins of phone and text (no bluetooth)
20 mins phone (bluetooth)
30 mins misc.
30 mins games.
20 texts.
Data on about 8 hours without Wifi and 4 on (N enabled)
1 hour browsing, emails etc.
30 mins with Microsoft Reader.
Probably a little more.
Also syncing a lot with calendars.
Not bad, but I feel like it could be better.
t-mobile usa.
I have 75% by end of the day
Adjust your PEAK TIMES for ActiveSync, that way your device isn't consistently trying to allocate resources to collect data such as emails.
Screen brightness, system volume, hibernating times, etc.
ALL OF THOSE are key factors in how quickly your battery will be drained. Anything involving the on-screen display is what will quickly deplete available battery life on a single charge. That may seem very "cliche" to say, but the fact is, this device has a 4.3-inch screen, so it's a power hog.
For today, it's been 17.5hrs since I unplugged and the phone has been mostly sitting except for a few occasional brief checks of the phone, 30minute email syncs, and a 15 minute phone call. It's at 40% battery after the 17.5hrs.
It did drop around 20% in the first 6hrs since the phone was in an area of horrible 0-1 bar reception. The rest of the time has been 2-3 bar reception.
17.5 hours @ 40%... are you serious?
My TMOUS HD2 has never gone more than 8 hours on a full battery charge. This is with "normal" usage. Regular email checks, activesync with direct push.
Comming from the Blackberry Bold II with 13-15 hours of battery under normal usage patters, the HD2 is VERY WEAK!!!.
I'm contemplating sacraficing the sleak look of the phone for the extended battery.
Anyone have the ex battery? How's your battery life?

If you need direct push in your life, then I suggest changing 3G to EDGE network.
Difference is quite noticeable.
It sucks,and if you want better battery life don't use it.I returned mine after 48hrs.
All the advice is great,but....
-If I have go from 3G to EDGE.
-Lower the brightness almost to the minimum.
-Set activesync up.....What is the point of having so much technology? if I can not use because the phone dies.
I need real time email and 3G to work,plus all the stupid menus that windows mobile still has made me change my mind.Microsoft has been in the market for a bunch of years and winmo still sucks.
Do not get to impressed with the HD and the movies,cause the thing dies in no time.
Don't buy it and stick with android.
I end the day with about 60% battery life left with mild-medium usage. A few phone calls, some maps/gps, active sync every 4 hours, facebook every 2 hours, weather every 3 hours.
VERY happy with battery life on this phone
i went all day yesterday (my first day with it) so i used it alot, took it of the charger, at 7:30am, and plugged it in last night at 10:00 and it was at 39%. that was BEFORE i turned off 3g(i dont get 3g in my area) so this hd2 blows the iphone battery out of the water....IMHO
my last device was blackberry 8900.
that thing lasted 3 days with moderate use. compared to that, 15 hour limit does suck, and there are times I don't want to use the phone to conserve the battery, which makes rage, but oh well. now I always carry an extra battery in my pocket, so that's a bit better. but that doesn't make it okay.
with the 3g off, wifi off, auto back light,running the energy rom apr 9. unplug on 9 am use about 100 sms and 10 minutes phone call with all the auto data off,just manual check weather and email twice still have 80% after 3pm.
turn off voice commends - this will help
Its getting better
I have recently done a few things to help the battery. I adjusted the the screen brightness to a comperable setting that a friend of mine has his set to on his iphone3gs I did not do anything to the 3g settings or anything like that. I set me email to sync every 4 hours. But my hotmail I just click send/receive and sync it myself. I play music all day on my phone. Check twitter internet facebooks while music is playing and a lot of texting over a hundred sent and recieved daily. Before I made a few tweeks it would kinda die quickly but now it appears to be a lot better.
My batter DOES NOT LAST FOR CRAP!!!!! I took it off charge at 8:13 and at 10:30 i checked my phone, it went from 100 percent to 81 percent. HOW DOES IT GO DOWN 19 percent in 2 hours when i didnt even USE the phone, i just hit the backlight to check the time, this battery is unacceptable everytime i check the phone the percent has dropped

Do you leave 3G turned on? Do you have your e-mail and/or weather checking themselves automatically?
The phone can certainly be doing things that consume the battery, even if you're not manually handling it at the time.
I don't understand why battery life seems to differ so much from phone to phone. My battery life is excellent and I use it a lot. I do have to charge it every night but I expect that from a smartphone. It always lasts me throughout the day with music, videos, calls, texts and web use on 3g. I couldn't be happier with the battery life of my phone.
PLEASE give me good tips how to save battery? BTW im using ENERGY's latest rom with cookie 1.7. i dont understand why i have to stop my email and turn off 3g when this phone is MEANT for these features. theres no point of a having an excellant phone when you cant use its features to its full potentiol without having it die within 10 hours( with moderate use)
Battery is weird
The other day i charged my hd2 fully then got on an airplane all connections were watch from paris with love which looks great on the phone landed after an hour and a half and my battery life was down to 15 percent i think i might have a bad battery when i am in the car i leave it on the charge and when i am in the hotels that i stay in it stays on the charge or plugged into my laptop and thoughts??
My battety lost One percent in one till ten minutes. I alrrady tried to delete the batterystats but it doesnt help. Any suggestions?
Were you doing anything on the phone, when it droppped 1% in 1 to 10 minutes?
regards
Nope. Even in offline mode it drops that fast.
You tried restarting the phone? I'd prolly try a factory reset after that if nothing changes. Other than that I have no ideas.
Regards
I tried restarting, different firmwares, flashing back to stock rom with nandroid. Nothing helped...
How old is the device, and how many times did you charge it 'till now?
I'm on my 4th day since last charge, and standing at 43%.
In anthing battery related, this phone is god.
Hey hi,
I know is frustrating.. but I think we can fix it ..
First we have to figure out what is taking the charge on your batteries.
First check if wifi or bluetooth is turned on. If yes turn it off.
Bring down the brightness of your screen
go to WIFI Settings and turn off the network notification
install Advanced task manager from Market and see the background application. Some might be running as default. But kill all for safer side.
When ever you open an application it stays on the memory u have to kill it using that tool.
OR
IF nothing worked jump into an other firm ware update. I have this android 2.2 i9000xxjp3 Its working very smooth But its an beta version. I am quit fine with that ..
I already did this. And nothing helped.
Similar to my thread:
http://forum.xda-developers.com/showthread.php?t=730302&page=2
Autokiller does not have any effect. I uninstalled all task managing sh*** and I can't find any significant difference.
However, I found after 5 charging cycles it was better than before (now 2/3 day instead of 1/2 day).
okay that's nice 2 know
I got eleven hours... Will see if ut gets better after some cycles. But i rly think its a battery or phone defect.
Hi i just did a battery test on 10 mins of wifi browsing battery drop from 65 and now 60 with 45 pages. Can someone do a similiar test to compare cause i think mine also a flaw set from samsung thnx in advance
How old is your SIM Card?
I know some old cards can drain battery hardly cause there is no power saving implementet, newer have better power management.
Maybe the card is defective. If you can, make a test with adiffetent SIM Card.
Send from my GT-I9000 (I9000XXJF3) using XDA App
The other day, My battery was pretty low, less than 10%. I checked battery usage, and everything was okay. But I made 10 mins of call, and that used 23% of the battery, and that's from a full charge ;
EDIT: current usage stats, from a 100% charge to 31% battery left.
13h 36m since unplugged
Display 31%
Cell standby 20%
Phone idle 14%
Maps 12%
Android System 7%
Voice calls 4% - Time on is 1m 32s. 70/100 = 0.7. 0.7*4 = 2.8%. 1m 32s = 92s. 2.8/92 = 0.0304... *60 = 1.826
So, 1.826% of the battery is used for each minute of voice calls, which means a full charge would last for around 55 mins of talk time. WTF
EDIT 2: I'm using stock European ROM, XXJF3(?)
Do you guys have power saving enabled on the LCD?
I too experienced similar problems with my battery, a single charge did not last more than 17 hours tops. However, since last charge now I have had it running for almost 48h. So what changed?
- I moved to a better coverage area for 3g, but having only 2g on didn't make a difference.
- I disabled powersaving on the LCD
- I uninstalled the widget "Weather from yr"
- I did a full depletion + charge with the phone OFF
After doing this my battery improved tenfold. While I before when checking "Battery History" in *#*#4636#*#* secret menu I had about 80% Running time. THis is now down to 18%. There was nothing before or now in partial wake, which led me to believe that my phone was actually never quite asleep.
So, try what I did, and see if that fixes your problem, it did that for me!
I'll try it. Yes, i rly have a very old sim card. I think i get a new one when my contract renews on a other carrier. Maybe it helps. Thanks fou your help guys.
1 percent in 10 minutes means absolutely nothing. Does your battery fall from 100 to 0 in 16 hours after doing NOTHING on the phone? (equivalent of 1 percent every 10 minutes.) Try this a few times. Check what's using the battery the most. Remember that with any smartphone on the market right now, the more you use the display, the considerably less battery time you will have; so 16 hours on one charge is completely normal if, say, you have 2 hour display on time throughout the day. it's not realistic to expect any better, and don't believe people who say they can go a full 2 days with moderate/heavy use - this really isn't possible unless you have turned off literally everything, in which case it stops being heavy use.

1 percent in 10 minutes means absolutely nothing. Does your battery fall from 100 to 0 in 16 hours after doing NOTHING on the phone? (equivalent of 1 percent every 10 minutes.) Try this a few times. Check what's using the battery the most.

Last time I was checking I had 34 hrs and 11% used for standby. Then I used GPS with screen on full brightness, had it set to WCDMA only with very bad coverage, was taking images and filming, watching video and surfing. I had no taskkiller or juice defender.
I easily get 48 hrs with a bit more moderate use.

Maybe you could enlighten us what your settings are.
My phone lasts no longer than 16 hours. But I also have Wifi, GPS, Bluetooth and Push Mail enabled most of the time and always 3G enabled (because otherwise I would have no use for a smartphone really).

Well, you have the same phone, they both have the same battery, they are both relatively new. If we put the phones side by side and did the same things on them are you really saying your phone lasts for twice as long as mine? REALLY? I'm sorry but through a day of what I would call "moderate" use, battery is uncomfortably low after at most 24-28 full hours (down to around 5%) and this seems to be the case with not just most galaxy S owners but pretty much every smartphone owner - it's very difficult to get the battery to last longer than 24 hours with "moderate" use.
What's your display use time at the end of those 48 hours you have the phone running for?

how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection

All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
