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
I just got a new arc from o2 UK a 3 days back..and the battery seems to be lasting just a few hours..say around 6-10 hours on light usage..
on the first day I let it discharge and then charged it to 100%...installed quite a few apps, games etc and the battery died out in a few hours....
I installed a task killer hoping it would kill the apps which keep starting...no change in battery...
then the next day I did a factory reset and installed only a few apps...ignored those auto-starting apps in the task killer...left it at 99% before sleeping and woke up after 10 hours with 57% battery...
I have another android device (dell streak) on which I use a custom ROM n a task killer..but I manage to get 17-20 hours on light-moderate usage..
I am not able to figure out why the arc's battery is discharging so fast...
do u think its a prob with my battery?...or am I doing something wrong?...oh btw...the battery use in 2.3 shows nothing significant..just the usual Wi-Fi, screen, phone idle...sometimes media and music(which I havent used)...
Any help would be appreciated...
thanks
There is a "Battery drain" thread somewhere here (maybe 2nd page).
Generally, the battery life is good. But check if the battery drain is after you have used the camera... it's an issue experienced by quite a few users.
Also, do you have auto sync set to too frequent? For testing purpose, disable background data and autosync.
oh ya...was searching thru the forum and didnt notice it before...lol..will chk it out..thanks..
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.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.
Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.
Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.
We will be adding Quadrant test 24,000 points on the original ROM.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.
I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.
But I'm happy with Cyanogenmod. Battery life is outstanding now.
My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.
I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.
Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.

Cyanogenmod has their own version of Exchange?
Our Exchange servers at work are ridiculously slow and unreliable. They can take two minutes to return your mail which is a major drain on your battery if it's set to check it every five minutes and you get a lot of mail. Sometimes they'll just stop responding and leave you hanging. The IT people just tell you to keep trying and you'll get your mail eventually.

Dunno.. 7-8 hrs I guess. Screen on time really doesnt mean much without any context.
I can get 12hrs+ watching videos on 20% brightness. I can kill it in 4 hrs playing games at 100%.
Like I said, the standby is excellent. Drains less than 10% in 2 days. So for me, I have about 90% to use over 2 days.. and from my experience,
video drains less than 10%/hr
gaming ~20%
reading books drains less than video.
General surfing, mails, social networking uses between 10-15% depending on how you are using it.
My brightness is usually around 40%. Goes up rarely when I'm using it bright conditions. Goes lower when I'm reading late at night
Should give you an indication of what you can expect from the battery depending on your usage..
Mine drains about 10% per hour while constantly using the device for light tasks, such as reading, web surfing, and watching some YT videos here and there. That increases to about 15%/hour when I watch movies. So after watching a 2 hour movie, I expect to see about 70-75% of battery left. Now if I'm listening to music for an hour at the gym with the screen turned off, it only drains about 3%.
At first, I thought that was pretty mediocre and felt disappointed. But I've taken my tablet with me on many trips and never had it die (usually just close to 20%). I rarely ever use my external battery pack. I know this will vary depending on how long the trip is and how much you're using it, but I'm just saying that it meets my needs despite having a lower battery life compared to some other tablets. I do all I can to extend it, but I don't have to constantly watch it.
Last night I charged the tab 100% and with Wifi off (sync for 1 min every hour. )
Today the battery is at 71% - On battery 13hours - 44 mins
27% Android OS
24% Google services
13% Android System
8% Onscreen time - 20 mins
Should I flash CM to fix this?

CM won't fix that. Install Better Battery Stats or Wakelock Detector to nail down the precise problem. If you're using them, it could be Exchange Services or Google Drive (yeah, that turkey wakelocked me to oblivion!), at which point you at least know what to attack.
You can find BB on XDA here and WakeLock Detector on XDA here, both are also in the Play Store.

Google search with 23 mins of wake time and Gmail with 6 mins.
Currently Deep sleep is 14 hr 26 mins. Total time is 17h 5m. Awake is 2h 39m. Screen on time - 27mins.
I added the google now widget a couple of weeks back and that caused some wakelocks and overnight battery drain. Removed it and didn't have the problem.
The battery life is pretty good for me. Was out a lot, so had wifi off for large parts.. watched videos (from device), read some books, played some Asphalt (not much.. around 30 mins) and some browsing/mails..
Got 11 hrs screen on over 2.5 days and still have 15% left.
Yeah was indoors so the brightness was never over a third (~30%) and reading books really doesnt drain much battery(especially if its at night and you turn the brightness further down)..
I'm not saying people will get 10+hrs screen on with their device and usage constantly.. 8hrs would be realistic.. but the point is, the battery is a lot better than I had originally expected.

I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time.

I have this same problem - except my GTP is 100% stock, unrooted. I can go into Settings/Battery to see that Exchange Services is chewing my battery. It will die in less than 24 hours, even if I don't use it - as long as it has a WiFi connection. I think if I turn off WiFi, it will stop attempting to sync and the battery will last "normally". I don't know for sure, though, as I haven't tried. I'm not interested in a tablet with no network connection or even without my email.
I'm going to cut a VERY long story short (at least, here) and say that I have spent several hours logging the ActiveSync traffic between my tab and my server, poring over the logs, and I have identified the problem. It's one particular item that is failing to sync, which causes the tablet to retry the sync every 1 second. The sync failure causes the server to log an internal server exception every time - despite the ActiveSync requests from the tablet being correct. I also found a Microsoft KB article that appears to address this exact problem, and MS has a hotfix available for it.
I have talked to Tech Support at my hosted Exchange provider and they have confirmed with their operations staff that my server does not have the MS patch that is referenced in the KB article installed. Unfortunately, they are giving me a bit of the runaround on installing it. I only have one mailbox hosted with them, so I have no pull. They sound like Verizon. "We have to thoroughly test this update in our lab before we can install it on your server." And "nobody else has reported this problem and we can't put too much time into a problem that only one user is experiencing."
So, I am now just waiting for them to install it on my Exchange server and see if it really does fix the problem for me. If it does, I will be posting about it on XDA and the AC forums, as a Google search showed me that a lot of people, with a lot of different Android devices, have this same problem and nobody seems to know what's really going on or how to fix it. I will try to remember to post back in the GTP General subforum specifically, too, so stay tuned.
My battery life seems to be getting better as the battery gets some more charges on it.
Sounds basic / silly, but i simply put mine in battery saver mode and that made a big difference with little effect on performance
