I was wondering, if I constantly am killing running process and they are always reloading (voice input, settings, gmail, market, etc), will this drain my battery faster? I'm at 76% with light use from a full charge and the phones been unplugged for around 4 1/2 hours.
That seems normal. mine usually dies within 6 hours, with all settings off. i think i need a new one. under battery settings it says display used 67 % of my battery life and for display time on it says 28 minutes
I've got my display using 73% followed by live wallpaper with 6%.
I mean Display% being higher just means you were actively using your phone more... or you set your timeout too high.
I don't think the actual restarting of the apps uses more battery vs them just running in the background all the time. Unless for some reason they restart almost instantly and you are constantly mashing the kill all apps button then maybe?
As far as your phone dying in 6 hours, that does not sound right at all. Mine definitely goes quite a bit longer than 6 hours consistently. It is currently at 38% battery after 17 hours 24m, with display having used 46% with 55m24s on. Part of that was while it was full brightness when I was outside. I have been at work though so its largely been sitting on my desk. Even when I first got it and was playing with it a ton it went well over 6 hours on a charge.
Some people do seem to have problems with battery life and I can only assume there's a bunch of bad batteries out there, or they are really hammering it..
I used about 25% in 6 hours today from normal usage* and that's even after driving around for half an hour streaming last.fm over bluetooth via 3G.. Sync switched on, wifi off, twitdroid running in the background. The only special thing I have is the setcpu idle tweak.
* Fair bit of browsing, some twitter, the usual 'ooh look you have a google phone' impromptu demos..
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.

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?
This is strange. I know everyone is probably sick of these battery discussion threads but something weird has been happening.
I have ATK and UltimateJuice and with the two I can go 8 hours at night and lose MAYBE 1% battery. If I then use the phone normally it will last about 2-3 days with around 1% loss per hour (more or less, depending). Well, I find after opening numerous apps the phone begins to lose more battery per hour, sometimes upwards of 3-5%. I check ATK and nothing has changed that I can see. After restarting the phone the charge lasts longer and depletes at a much slower rate. So, this begs me to ask:
What is causing this and why?
and, How can I stop it?
All insight is appreciated! Thanks.
Notes: - same location for both cases
- WiFi enabled in both cases
- GTalk and syncing the same
Anyone at all?
i have an average of 8-9% battery loss overnight with only Google account on an active sync. over the day it'll drain randomly too. sadly.
no idea why but i'm living with it.
People well tell you not to but get ATK. I ignore all apps for syncing and important stuff and have it kill stuff like gallery, etc. I found it helped a lot with saving battery. UltimateJuice helps a lot with battery as well. I'm at 70% and it has been over a day an a half now.
the think i learned about all those auto *whatever* programs, they always end up causing more problem than what they solve
i only use them to manually end task apps that i don't want to have in memory anymore
otherwise i just leave them running
no effects on battery life
the battery life is more related to the WiFi usage & GPS usage
if you are not using any of those 2 just manually slide down the tab and click them off
you can go a whole 24+ hr if you keep GPS and WiFi off, and only use 3G/voice in moderation
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%.

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.
Please check battery history with the android system tool and also more detailed info accesible with this widget: http://www.appbrain.com/app/quick-battery/com.bwx.qs.battery

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.
How is the battery life compared to previous state? Better, worse or about the same? Please vote
It will be the same for the first 3 days and then gets better by a whole one more day (Don't know why).
For me the counter at the 1st 3 days said it will last for 1 day and 18 hours now it says that it will last for more tan 2 days and 18 hours and some times 3 days and 5 hours.
I tested it and it lasted for 2 days and 11 hours and there was still 17% of battery life (Lite usage , some 3g usage and listening for 30 minutes for music and around 2 to 3 calls of 15 minutes total).
Hope that helps
It does, thanks! Replies are welcome and there's a poll on top so please vote
I leave WiFi and data connection switched on all te time ... I used to get about 18 hours ... Still get Te same ... Comparing 7720 RTM with official mango update ...
Sent from my SGH-i917 using XDA Windows Phone 7 App
Battery life on my focus with mango and even before mango has been better than any other smartphone ive owned. I cant complain at all.
I was going to post a message on the battery too.
Poll is a great idea.
I just finished charging it after installing Mango. I will see how much it lasts.
I wanted it to drain out and recharge it so I can see how it is with Mango. It didn't gave up easily.
My initial impression is that battery is improved.
However, when talking about battery life, it's crucial to keep in mind what services the phone is using and what apps are installed.
For example, things like sound enabled for key presses, or having WiFi on or off, whether you play games, what apps you run, etc are important.
For my test, I want to see how long the battery lasts with a very basic usage. WiFi turned off, without running too much app or play games, giving\receiving few calls(I do not talk too much on the phone).
I heard for example that Samsung app Now drains out battery pretty fast.
Also, lack of signal in some areas, also means alot for power consumption.
6 days + 7 hours
Usage:
no WiFI enabled
no games played
max 2 hours of talks in total(I talked once like 1 hour)
How does it sound to you?
For me it looks fine although I am wondering how much would it last if I have Wifi enabled(for the same amount of talking duration).
6 days, What?
I only get 3 days and 15 hours if not using the mobile phone at all.
Can you please post a screen shot of the battery saver
I am in the 7th day actually now
The statistics displayed in battery saver are very wrong. I am not sure how it computes the remaining time.
When I posted yesterday, it showed 6 days since charging and only few hours remaining.
Now it says, 7 days and 1 hour since charging, remaining: "less then 1 hour", remaining battery life: 6%.
Last time I charged, I noticed that battery doesn't get to 0%, most probably it needs some energy to preserve data, so it will probably only keep me for few hours today.
I will post a photo soon, right now I don't have other device to take a photo of it.
Last time I fully charged the phone was when it was completely empty. Maybe it's important.
I can only hope the battery life won't degrade in the next year.
Ok, so now we have some votes so I can share my bits and why I started this thread.
Before 7720 I was on 7660 (Mango Beta1, not 7712)
The battery was certainly better than in NoDo. Actually, I'd say my phone had the best battery lifespan in 7660, than in all other versions.
7660:
Standby: 3+ days.
Night stand-by: 3% consumed (cca 7-8h)
On average use: 1 day and 20h
For me, average use means:
- Cellular data connection on during the day (I switch it off during the night)
- Some wi-fi to check new apps, say 20 mins daily
- About 1-2h playing.
- Minimal calling (several minutes).
7720:
Standby: almost 3 days
Night stand-by: 4%
On average use: 1 day and 10h
Stand-by means no data connections.
As an observation, stand-by time is almost similar. There is a noticeable drop in battery time once data connections come in play (cca 10-20% for me, compared to 7660). I am not going to revert to 7660 to re-test.
One more thing: after upgrading to Mango, I had AccuWeather app installed and running in background. I had to disable it because the battery life was getting under 24h (actually more like 20h). So if you have apps that run in the background, that might be one of the reasons why the battery life dropped for you. Once I disabled it from working on the background, I'm experiencing very similar times to 7660, but still the data connections consume just a bit more.
How are people getting 3+ days!? When at 100%, my Focus usually says like 12-13 hours. I have a Gmail email account set to push, and a Hotmail account set to receive email every hour. I have Facebook, Twitter and LinkedIn linked on my phone. I have Messenger and Facebook Chat set to off. I always have wifi/bluetooth off, unless I need it for a few minutes.
I am thinking I should flash to 7004 again and update to Mango from the beginning.
I walshed my phone for Nodo, then did the fix, then used the windowsphonehacker method for Mango and got the "Samsung Update" when Mango was released.
Thinking maybe my install is just a little off due to the route I took to get here.
Anyone else have battery life as bad as I do? If I use my phone non-stop for like an hour (people hub, web browsing, facebook app, etc...) I can burn through a ton of battery.

Make sure to do a reset immediately after the update to the *official* Mango (not the tricked one).
The BL seems to be much better and is a small cost for the rewards. You will erase your phone, but it's worth it. The BL seems to be much better than NoDo.
To increase battery life when you have data connections on:
- keep the brightness to low
- keep the ringer on vibrate when you can
- disable background apps
- don't keep applications opened in the background
These save me a good % of battery on a daily basis.
Also, unless really necessary, disable data connections during the night.
@rkremers: with the above settings and no data connection I get 3-4% loss evey 8h or so. If you calculate, that's about 12% per day. Which gives about 9 days for standby, as someone else on the forum was saying, which I incline to believe. This weekend I will test this too. I won't touch the phone at all until Sunday evening. So I'll have the power consumption on standby for 2 days.
dang enderpsp... Now I'm for sure gonna flash to 7004 and start from scratch, to see if it gets better. Probably do it Sunday sometime due to busy Friday night/Saturday.
Thanks for weighing in...

You're welcome. Keep in mind that a "tired" battery can also be responsible. I see lots of wrong advice given across the forum.
How to Prolong Lithium-based Batteries is a long read, but in the long run, you'll benefit from it, as a lot of devices use nowadays these types of batteries, including cars!
LE: As a refresher for me, I searched again and found this. While it's not as detailed as the one above, it contains good advice.
so, I flashed to 7004, then let Zune upgrade to Mango... I'm at 95% battery now, and it says 1 day 5 hours... 1 day 10 hours with battery saver on.
Not sure if it will actually last that long, but before I did this, it would say about 13 hours on a full charge with battery saver on... so clearly my phone did not like being walshed, unwalshed, hacked to mango, etc... Guess in the future I'll install leaked versions of WP7, but go back to zero when they officially release.
I finished the weekend standby test (2 days). This battery is 9 months old.
Setup:
- Battery saver off
- No data connections/wifi
- Sound on
- Low brightness
- No alarms
- No background apps
- No touching the phone
After 24h: 91%
After 48h: 79%
Had a phone call (didn't answer) and one alert (didn't dismiss), in the second day. After 24h I just turned on to check battery status (<20s).
The end result speaks for itself, approx 10% battery per day. So, it can give 9+ days on standby.
Next weekend I'll do the same test with battery saver on and update here.
I just got a Samsung Focus and the battery seems to lose power at the rate of 2% an hour. Is this normal? data connection is not active, no games, no youtube videos just a quick e-mail check and 2-3 min call.
Is this likely to improve after a few more battery charge cycles? I have followed all instructions like disabling location services and background apps.

How is the antenna signal? What type of connection?
Antenna signal is pretty good 4-5 bars. Just regular connection not 3g. E-mail auto syncs have been set to manual.
Battery seems to be original Samsung.
