[Q] Please help with my battery life!!!

Hi guys, I love my SGS, but the battery life is killing me!!
I've tried 3 different ROMS, but all pretty much the same. I'm now on the 'official' JP6 / JPM. Phone is rooted, and One Click Lagfix running.
Display is set to minimum.
I sync an Exchange account using push. I've turned off gmail and facebook sync.
Using LauncherPro.
Basically, I unplug the phone from the charger at around 7am, and by 5pm it is dead!!
!!
Any suggestions!?

1: change your push-settings for exchange to 30 mins or an hour ( i did too , its better )
2: buy a extra battery
3: bring your charger to work
4: stop playing non-stop with your phone
to sum it up. we cant tell you what u are doing wrong with the small info u gave. you dont give % of battery usage ( liek 60 % display, 20 % standby etc )
all in all, i can say atm. stop push-mail
( i have same prob , i just leave my USB charger @ work lol)

root it again.

Also set phone to 2g mode rather then 3g and install juicedefender with nobars too.

There is no proof that 2g eats less battery

2g relly eats less that 3g. But i'm use both + wifi at home + look a flash video, get rss every hour and phone lives 36-48 hours on one standard battery. Maby your battery is dead. Replase it

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

eh?
what would you like as a proof?
sure if you live under the antenna consumption may be the same, but 2g is much less processor intensive and has longer range.
so your phone works half as hard in 2g than 3g (both idle and on line)
with just 2g and only using phone features i can go 5-6 days
same usage with 3g goes down to 3 days
and that is with having mobile data off in both cases

2G eats muuuch much less battery. I didn't have 3G for a few weeks, huge difference in battery life.
I use Juicedefender just so that nothing goes on with my phone while the screen is off, only update rss/weather/sync when sync is on.

Can anyone confirm if this method works?
(On a side note: I'm looking for someone who can help me flash Korean firmware onto European phone so I can get "record call" feature. Thanks)

I manage to get 3+ days of battery time... I have data connection inactive, no syncs, and using a black theme Battery life just improves over time, after like 5 or 6 cycles of charging.

I've had my phone for a little less than 2-3 weeks. While my battery has gotten better with a few full discharge/charges, I still haven't reached those insane battery life times that some have had the luck of having.
I've done the full discharge method a few times. I've also done the "charge (on), unplug, charge (off), turn on for a few minutes, turn off, charge (off), method twice.
I have juice defender to set to keep everything off and only connect for 1 m every 15 m. I have root, but I've removed lagfix.
Yesterday night, I slept for around 6-7 hours. My battery life dropped a full 40%!
Here are my battery usage stats:
Display 44%
Cell Standby 20%
Android OS 14%
Phone Idle 13%
Android System 5%
I'm wondering if my phone or battery is defective and I should ask for a replacement?

Hey, try the 5min evey 2hours, that's what i have and i don't have any issues.
Obviously something is wrong. THis happened to me before, it was because of FB and google sync as well as the widgets constantly synchronizing and using mad data.

Welcome to the SGS.
Typical usuage for my SGS:
0800 - alarm used to wake me up.
0805 - disconnect from charger - full battery
Sync: K9 Mail - once an hour, headers only or messages less than 2Kb.
JuiceDefender: Data connects 5mins every 30 mins, otherwise 3g radio or wifi is deactivated.
Average time on 'phone calls: 10 mins.
Wireless use in work: 20mins max
3G/2G usage: 20 mins.
Brightness set to lowest setting.
Doing the above will empty a fully charged battery by about 1800, or usually sooner.
9 hours of use until empty, when the 'phone is predominately on stand-by.
The wireless and 2g/3g data radios are a real killer. With the data connection of, then I can watch the whole of the Avatar film on the device, and even have some power left over from some 'phone calls.
Solution: Don't use the SGS for data while not running from the mains power. It'll save the battery.
So, don't use the SGS for business. Its an expensive toy that pretends to be mobile, because really one it tethered to an electricity socket. Welcome to Android 'phones. Other than the lag that causes the 'phone to be unresponsive for a couple of mins, I like the device.

check your apps, I used to use widget locker and it'd drain about 30% a night. I dropped it even though I used to love it, I think they pushed out a bad update 2-3 months ago and never made it better.

Hrmmm, I don't have any out of the ordinary apps running. I've made an effort to check all apps and ensure they don't auto sync/auto - update or do so very rarely.
Apps I have:
Juice Defender
AutoKiller Memory Optimizer
Facebook
Whatsapp
Yelp
Uninstalled Tango
Uninstalled Samsung Apps
SMS Time Fix
The rest of my apps are either stock or don't use internet

At some point I shall do a factory reset and start again.

* In most phones when switching from 3g towards 2g will result in +1/3rd increment of batter-life
* Extra launchers(UI) will play a lot with your battery, best is to have only one running, not TW along with launcherpro
* Turn OFF the gps cos i noticed, by keeping it on, that it's a huge drain on the batterylife.
* check apps and be sure none will run in the background with adds (remove them with an add remover)
* flash to jpk and root with oclf, many complain about their roms, but after 130 apps and a month mine is still working splendidly, with maybe and just maybe the lagg once a week. (could be titaniumbackup at that moment)
downloaded a thing and send a few messages and it's at 85% atm, that's after +6 hours of use. (it was at 98% after 4 hours with a few uses)

Ok guys, Dark Steel JP6/JPM, hardly any apps, 1 Exchnge account.
I took the phone off charge at around 10am this morning, now at 6.30pm, down to only 16% left!!
Stats:
Display - 77%
Cell Standby - 17%
Phone Idle - 6%
I don't get this, the battery life is awful!! I've hardly used the phone today. Display brightness is set to absolutely minimum. 30 second timeout, and hardly used, so the screen has hardly been on!
Apps I have:
Flash 10.1
SetCPU
Remote Desktop
LauncherPro
Smart Keyboard Pro
ROM Manager
SGS Tools
Spare Parts
Plus the normal Maps, Navigation, Flash.
GPS Off. 1 Exchange account set to Push. Gmail sync turned off. Bluetooth used for around 30 minutes.
Please help me!!!! I've tried 3 different batteries by the way, so it's not that!
How many charge cycles does it need to sort itself out after deleting battery stats (deleted via clockworkmod recovery)?
Thanks!!!!

Your phone idle is only 6%, something is stopping the phone from sleeping. Give us the reported times for display, idle, e.t.c

Typical battery life so far?

Can people post their typical battery life times with the D3 so far, to get a feel for how good this is (hoping its a bit better than the JUST one day maybe) of most phones nowadays)

Well, lets see. I have set the radio to CDMA mode only, purchased the extended battery (+400mAH extra) and have GPS turned ON, Brightness at 70%, and Sync is ON.
Yesterday, I got to 70% after 14 hours of being on battery. This was with light use. 1/2 hour phone call, a few text messages, etc.
Today, I've been on battery for ~8 hours, and I'm at 80%.
A few days ago. I went a solid 8 hours of heavy use: using maps/navigator for about 20 minutes, texting, watched a part of an HD movie for 10 minutes. Had WIFI turned ON. Took some pictures, recorded video in 1080p, etc. My percentage was at 30% before I connected the battery charger.
Edit: My prediction: Once you have fun with the phone, set it up, get use to it, and then switch to using it for daily stuff.. texting, some calls, check your bank, watch a youtube video, etc... you can most likely get this phone to last more than a day on battery power. For me, as long as it gets me from wake-up in the morning to bed at night on just battery power, it's good.

I've got the extended battery, first day usage running it dead got about 38 hours. About 6-7 hours on the phone, some internet and a bit of texting. Suprising thing is, display is only using about 2-3% of the battery usage. Most is Cell Standby and Phone idle, both about 30% each.

Weird, I was getting horrible battery life with the standard battery, about 8 hours even with CDMA only. I put in the extended and maybe got 9.5 hours.
Today at home I have been using it moderately with GPS, WiFi, and mobile radio on and am at 70% at nearly 10 hours of use on the extended battery. Crazy, don't know what changed, maybe my signal at work really sucks...

14 hours 32 mins on my first full drain. That was with some decent usage. I'm probably going to pick up an extended battery though

Pictures say it all. This is with moderate to light usage. Some phone calls, text messages, browsing facebook, etc.
Display Brightness is AUTO and I have the extended battery installed.

Ditto. I was at a little over 30 hours today and at 40% when I plugged my D3 in. This is pretty normal for light days.

Hmmm something must be wrong with mine. My girlfriend's and mine have been getting around 11-14 hours on a charge. A "charge" would be when it gets down to at least 15-20%.
I don't have any widgets running really, except that stupid Verizon data app sometimes seems to keep trying to access something when I'm on wifi.

Not too good for me here. Down to 70% with barely any usage after about 4 hours. 36% of that use is cell standby, and 32% is phone idle. 16% system and the rest is apps and all are under 5%.
I barely even use the phone itself and haven't even made or received a call since getting the D3. Today so far I've sent 4-5 texts and checked email a couple of times so for it to be down to 70% is crap.
I'm giving serious thought to returning it and sticking with my OG for a while longer. It was running CM7 with stock kernel and lasted considerably longer with heavy use.

Took off charger at 720am and at 942 its at 80% no good, made two 2 min calls and had some txt and iys already draining, I don't have really anything syncing and im on cdma

Does everyone do the sync every X minutes or on push? I'm using push and that's probably what's draining the **** out of my battery.

For everyone having trouble with their battery: Have you changed your mobile network to "CDMA Only"?
If you haven't done such a thing, here is how to do it:
- At your home screen, Press you Menu Softkey and choose "Settings"
- Then choose "Wireless & Networks" at the top of the menu
- Select "Mobile Networks" at the bottom of that menu
- Choose "Network Mode" and select "CDMA Only"
If your settings were set to Global, then the system would be going between CDMA and GSM every time you signal was weak or it was trying to acquire a signal. By selecting CDMA only (Verizon's Home Network) Then you are telling your phone you are in the United States and to stop looking for other types of networks. This should greatly improve battery life, as it did for me.

Awesome, I'll try to remember to report back here my results.

I've done the CDMA only with HOME only selected.
6 hours and 40 mins since taking off charger, and down to 50%. About the same as yesterday.
38% of it cell standby,
34% phone idle,
18% android system,
6% display,
4% android os and
2% maps is the whole list of my usage since then.

It's a bit early to tell, but yesterday I decided maybe switching to CDMA only was meaningless while the SIM card was still installed. It's only been off the charger for a bit over an hour but I'm still at 100%. Typically it's been dropping about 10% an hour or so. Will update after a few more hours of use.

My battery life has been sucking. I am around 50 percent after a days use at work. With my Droid Inc 1 it was around 75 percent. I have it in cdma mode.
Cell Standby 39%
Wifi- 29%
Phone Idle- 26%
Display 4%
Android Os 2%
Android System 2%
Doesnt make sense. The Inc was rooted too running CM 7. Cant make that big of a difference.

After 6 hours I was only down to 70%. Typically I would be at 50 or even hitting 40 so there seems to be some improvement. I also noticed that despite having set it to CDMA only, after pulling the sim card, it was set back to global.

I have only had the D3 for a few days, and so far I can get a full day out of the battery. I listen to music via bluetooth FIPO all day (+9 hours) and I'm generally around 20% when I get home. However, recently the Social Location app has been going nuts. See attached...

So you've seen an improvement in battery life after taking out the sim card? Has your cell standby percentage decreased?

With my display on auto and moderate texting. Ill usually last from 10AM in the morning to like 11pm and still have like 30% left.

Battery Drains during Standby Mode

Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.
Wifi and Bluetooth: OFF when not used
Use Packet Data and Data Roaming: OFF
Network Mode: GSM Only
Auto Sync: OFF
Auto Brightness (Display): OFF and scale is at the most left
Animation (Display): No Animations Shown
Screen Timeout: 30 seconds
Use Wireless Networks/GPS Satellites: OFF
Power Saving: ON at 50%

Any feedback or comment on this matter would be really much appreciated. Thanks!

From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!

Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes

Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.

Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.

Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!

i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??

You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.

Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.
Gesendet von meinem ARCHOS 101G9 mit Tapatalk 2

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.

thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

@TempusFudgeIt
That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.

Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?

I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!

[Q] HTC One Battery Life

Hi all,
I have a att HTC one m7 running sixth sense with the stock kernel. Just checking on my battery life. With power saver on and brightness set to minimum with location off and LTE on, I have 2:41 screen on time with 36% left in the tank. I bought my phone August last year. Is this normal battery life?

Basically no, what's hogging up your battery life? (Any apps running in the background for example?)

Well gsam says apps are using 57.5% with screen using 34%. The top offenders in apps are chrome at 12%, system... At 9.3%, and android system also at 9.3%, and kernel at 5.6%.The HTC battery utility says android system is using 80% in app usage

I have been looking at this forever now... its this keep alive sob. a lot of people is having this issue

Well the official sense 6 update will be coming out soon, I'll update to that. Think that will fix the issue?

i already updated to sence 6, nope.

this is my phone's normal activity, when no app is running in the back ground.

If you go into Power > History - is your awake bar almost solid color? Looks like some app or setting won't let the phone go to Deep Sleep, causing battery issues.

After converting back to stock with power saver on and brightness set to low, I'm at 3 hours screen on time with 48% left. Is this more normal?

Depends on what programs did you use and if you had Wifi/Mobile internet connection. As always, showing screens from a battery app (GSAM/BBS) makes it much easier to decide.
For example on WiFi the longest screen on time I had was 6Hrs 16 mins with 23% left - I watched 3 movies in a day with headphones.
But usually I am getting 2-3 hours screen on per charge if I use my phone "normally" and not watching movies.

HTC One (M7) battery life after 1 year

Hello guys,
after 1 year usage of my HTC One I'm still very satisfied with that phone :good:. The only problem is the battery doesn't last as long as in the beginning. I'm running the original htc sense with android 4.4.2. I don't even get through the whole day with hardly any usage. For example: I undock the phone in the morning (about 6.00 am), until now (10.00 am) I watched about one 5 minute video, listened to music for about 10 minutes and used facebook for a few times. I only got about 60% left. This is quite less, as I have done everything possible to reduce battery usage. I did disable vibration on keyboar, disabled all not used connections (bluetooth, nfc, ..), reduced display brightness, disabled not used applications.
How long does your device last? Is this extreme draining of battery usual?
best Regards
