What is your display power drain?

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%.

Sweet, thanks for the info. It seems my battery is also slowly "training" its way closer to these numbers.

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.

Battery drains as fast as hell

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.

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.

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?

[Q] Battery issues

Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?

Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.

Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??

Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...

Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_

this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.

Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

Change the battery...

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........

Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?

Warning: Do not install 2.1.4 firmware

Okay, just a warning. This firmware is a battery destroyer. Within 11 minutes my battery has dropped 10% and I have no running background processes and I'm not doing anything with the unit. Just checking the screen once in a while. I've actually watched it go down 1% in a minute.
I'm telling you...if you have not installed this update...don't do it!

Too late for me.. already updated. I'll keep an eye on my battery level and let you know if I notice it go down faster than normal.
I just unpluged from the charger. It is at 100%.. I'll let you know where it is in 1 hour. I'll turn on display to stay on to simulate being used and then let it set.
Edit: Okay after 10 minutes.. still at 100% screen always on.. that was with whatever programs load into the background after boot.. I haven't killed any apps. I now have launched my Pykl3 Radar app to increase cpu from 300Mhz to 1000Mhz.. it refreshes the radar screen every 5 minutes.. we'll see how the battery does with the processor working harder.

I'm not noticing any difference really... Same battery life as before(I think, I haven't done any formal battery life tests or anything)

Seems fine for me too, but I'll go ahead and do this test.
Edit1: After 30 minutes it is still at 100%.
Edit2: After 35 minutes it has gone down to 99%
Edit3: After 60 minutes it has gone down to 96%
Edit4: After 90 minutes it has gone down to 90%
Edit5: After 2 hours it has gone down to 82%
Edit6: After 2.5 hours it has gone down to 76%
Edit7: After 3 hours it has gone down to 67%
Edit8: After 3.5 hour it has gone down to 61%
Edit9: After 4 hours it has gone down to 55%
Edit10: After 4.5 hours it has gone down to 50%
Edit11: After 5 hours it has gone down to 46%
Edit12: After 5.5 hours it has gone down to 44%
Edit13: After 6 hours it has gone down to 40%
So this averages out to a discharge rate of 10%/hr
This test was done with the screen fully on the whole time. Mostly running at full 1000Mhz and with wifi on and downloading data every 5 or so minutes.
If I let it run down to 20%, I would probably get about 8 hours which is within the specs of the Archos 101.
I was pushing the device harder than average and I believe in normal use I could get more than 10 hours.
So I conclude the battery problems aren't related to the latest firmware release 2.1.04.

Yeah, looks like you might just have a problem with your device. Have you tried reformatting and reinstall?
After about 4 hours of usage (mostly Wordfeud) with Softlocker active (keeps device awake when screen is off) I still have 82%.

Same here, no battery issues at all.

Okay, just a warning. This firmware is a battery destroyer. Within 11 minutes my battery has dropped 10% and I have no running background processes and I'm not doing anything with the unit. Just checking the screen once in a while. I've actually watched it go down 1% in a minute.
I'm telling you...if you have not installed this update...don't do it!

Saying that your battery is depleting at 1% per minute is useless information given that many electronic devices can sometimes drop by 20% in 1 second
Please only evalute battery usage by observing how much time it takes to fully discharge.

Yesterday I updated to 2.1.4 and really have not noticed any battery drainage. No issue from my side.

Updating last night on Archos 70 8GB, after fully charged all night and playing net for 20 minutes continuously, battery drops to 99%. No sign of drainage too.

don't see any issue on battery drainage on my Archos 70IT either =)

It is interesting, but in this thread I appear to be the odd freak out and no one is having any issue except me...yet in the other 2.1.4 thread, a lot of people are experiencing this battery problem...not sure why that is, but the problem is there and it is real even if it is hit or miss on people experiencing it.

Yep, it's real. I put in a service ticket. I wiped and reloaded my a70 today, but it was still drawing over 800 ma listening to Pandora. I only had about 30% left on the battery, and I wanted to completely discharge it. It's stone dead and on the charge right now. I'll find out early if it helped. 3am start tomorrow. Goodnight.

(first post ) I just installed firmware 2.1.4 yesterday, and haven't noticed any difference in battery life. Although, I have noticed that 3d games obliterate my battery life now, where they just ate it before.

Wiped, reloaded, completely discharged, and charged over night. Down 20% the first hour.

Mine is still around 10% drop every hour I have wifi on for net surfing. Mine just upgraded from 2.1.2, just for information.

don't see any issue on battery drainage on my Archos 101 IT either

One thing I am noticing is that is seems more sensitive to cranking up the processor to somewhere between 600Mhz and 1Ghz at various times. Before it wasn't as sensitive and often would stay in the 300-600 range for me. This change may be why people have noticed "increased performance/less lag?"
That might be part of the drain issue or something else.
I think the point is that it is hit or miss out there. Some people get the glitch and some don't. Regardless, Archos needs to address the problem.

Ok, now this is interesting. Just to try something different, I reformatted my tablet this time and installed 2.1.3, then restored everything with Titanium. I seemed to be holding up much better. After an hour it had barely dropped. To put it to the test I drove home from work with bt gps and google maps via tether. All tolled, in 2 hours it dropped about 10%. I thought I had it fixed. Then I realized I hadn't rebooted after restoring with Titanium, so it was still rooted. I rebooted it and the wheels came off. It dropped over 10% in about 20 minutes. I ran the root app again and it leveled right off. It's down to 10% now so I have to charge it before I can experiment more, but maybe someone else can try and see if they see the same thing.

Maybe root has something to do with it.. I've never rooted and don't have a problem.. I wonder if the only people having problems are the ones that rooted.. although it sounds backwards in your case.

I was wondering the same thing. It also seems to have to do with wifi, because with it off it draws almost nothing. The exploit has something to do with the wifi, so who knows.

Huge battery drain: Awake screen off

Hi
Brand new phone here, not rooted and fully stock.
During last three days I noticed a huge battery drain overnight, so I installed Better Battery Stats. Being not rooted I don't see many info but one thing is clear: after 6h being idle, I have lost 17% and BBS shows one single line as per attached screenshot.
Any idea what's going on?
Thanks

try turning off wifi and anything that syncs constantly. go into settings, battery and see what it shows. no need for an extra app.

????
I don't want to turn off wifi at night.
With my edge+ all was remaining on and I would use only 4% overnight

I have the same problem. Go to sleep at night and wake up 7 hours later with 40% drain during the night. I don't use wifi.

I've had this phone for a week, and the first 3 days all was ok, but during the last 3 nights I am experiencing this huge drain overnight.
Problem is I am not rooted (and am not willing to root right now, till Android N comes) so I cannot really use wakelock detectors to see what's going on.
Phone is set up exactly like my Samsung S6 Edge+ and this one drain max 5% overnight.

Again go into settings and battery and see what is being used

Ok tonight I'll check

Here it is.
Unplugged and left 6h idle overnight with wifi on.
Lost 12℅
I cannot understand what's going on

Tonight lost 20%

Please note this happens only at night while phone is idle.
During day battery seems OK and wifi or idle do not show up in battery usage.
Also from the screenshot I see only 1% and a very low mA usage, so I don't understand why I lose so much battery when nothing is going on.

Is this really a problem? Your phone is losing between 2% and 3.3% per hour. That doesn't seem that bad. Mine is around 6% during the day (I have it plugged in during the night).

2% per hour in doze at night is a huge problem

Yeah, that kind of drain is an issue. I lose like 1% every 6 or 7 hours overnight with phone in doze with 2 maint. cycles
