My 8125 is suddenly running out of batteries very fast. I suspect this is because of some activity running - if I turn the unit off, and leave it on my desk overnight, it is exhausted by morning (I, on the other hand, am exhausted by morning only if I am turned on. Sorry.)
I have checked for:
alarms and notifcations that are set to go off - there seem to be none
mail and other internet access items - there seem to be none
programs (like SPB Weather) updating themselves too frequently - there seem to be none
My energy settings are normal; sleep in one minute, backlight down, etc.
Is there anything I'm missing? Any suggestions?
wifi, bluetooth. make sure they are turned off.
That's exactly, WiFi and BT even when active in standby really drain the battery quickly.
thanks so much, but.... Wifi and Bluetooth are off - I never turn Wifi on, and I almost always keep Bluetooth off (though I wish there was a way to quickly - or even automatically - turn it on or off, ie, whenever I use it in phone mode, BT would turn on, and when I hang up, it turns off.)
any other thoughts?
Battery Gone Bad
Hey I think your battery is gone bad.
BT Off
Wifi Off
Backlight Down
Sounds to me battery is ready to go to the recycle bin lol
Also check your MSN Msnger Is not onn all the time.

maybe it is the battery. the unit is less than a month old, but I just bought a spare battery. I'll compare run-down times on both.
a related question: why would WiFi and Bluetooth consume battery power if the unit is asleep?
-thanks-
I started getting horrible life out of my battery as of last month, but then I upgraded the ROM on it and have been getting FANTASTIC battery life. Better than when I first got the device.
which Rom did you upgrade to?
Summter <sp?> 2.3 for Cingular

Did you solve your battery problme?
when i am out in the country, where i might rarely get a signal, my battery drains real fast, prob to do with the constant searching for a signal to connect to.
I came upon this thread after my 8125 began having problems with the battery life last week. I'm wondering what kind of battery life people are getting and which settings they have.
For instance, before last week, I was getting little battery drainage during a 9 hour shift at work. Then this week, I was getting close to 55% battery drainage over the same duration. Just a few moments ago, I checked my battery settings and I found out that for some reason, my phone wasn't shut off after 2 minutes of idle time as it was originally set at. Okay, I'll test my battery usage tomorrow at work, but I suspect that was the problem.
Then it got me wondering how long other people have for battery life. With Bluetooth on, wifi off, lowest brightness setting and my auto shut off set at 2 minutes, I was able to last an entire 9 hour shift on standby with only about 4 - 5% drop in battery life. Hopefully, that is what I'll have tomorrow when I test it again with the auto shut off setting in place. What are others getting for battery life (please specify your settings).
I've forgotten to charge my phone at night before, and have had no problems making it through the second day of usage, though I'll usually get a low battery warning.
I keep Bluetooth and data connection on constantly. Don't use Wi-Fi unless I need something really quickly. Backlight is at the lowest active setting. I would say I use it moderately throughout the day. I use it to take important notes and make reminders for myself, along with surfing the internet without worry.
hi
Please check out activesync which drains the max battery..
make sure that activesync is not running in backround. once after disconnecting your mini-usb cable connectivity from PC please check for the activesync status.. if running turn it off.

Ok so I received my Vibrant on Monday and so far I am in love with it. Their are three things that bug me, however.
1. Battery Life is TERRIBLE. I know, I know-This has been discussed before but I did everything the other threads said and still no difference. On my phone, I will leave it on standby and it will drop 8 percent in like an hour and a half. Somethings wrong. Also, If I play the Sims for two hours (like I did today) my battery goes from 98% down to 45%. Is this normal?
Just to point out what I have going on with my phone:
- Brightness is turned down COMPLETELY. Automatic brightness is turned OFF.
- 3G is always on. Could this be the culprit?
- I have a completely black background.
- Last I checked, it said my display was taking up 60-70% of my battery usage.
- As stated above, Sims DRAINS my battery. Either somethings up with my phone or Samsung should have made sure the Sims doesnt kill the device.
2. The second I take my phone off the charger, the battery goes from 100% to 98%. Can I fix this? Its kind of annoying...
3. Problem with the Sims. Im not sure if any of you have this issue, but whenever I tell my Sim to watch TV, the app shuts down and takes me back to my home screen. Any idea why its happening?

1. Leaving a phone in 3G all the time is not a good idea, if you have WiFi near you you can connect to I'd use WiFi instead, it has less battery drain then the antenna that is constantly searching for 3G signal - unless you are in the area with bulletproof 3G coverage of course.
2. It seems like this bug is common 100% jumps to 98% once you unplug the charger, are there really any accurate battery meters on the market?
3. Can't help you there, not playing the game on my phone.

alright thanks. im in phoenix here so i am almost always in a 3G area. I guess i'll leave it on since i rarely dont have 3G
I also read on multiple forums including HoFo that 3G generally consumes more energy then WiFi.
sims 3 fix
so my girlfriend was complaining about sims crashing when she watched tv or relaxed on the couch. i fixed this by moving both the sims launcher app and the sims game app to data/app.
I normally use Edge simply because I don't need Wifi or 3G on unless I'm doing some heavy data transferring.
Currently I'm at 61% battery, which means my phone has been off the charger for 16hours. Its not a fluke either because its just normal use for me. I normally take my phone off the charger at 6am and I plug it back in around 11pm.
Prolonged GPS, Wifi and 3G will eat your battery. I'm not saying don't use the services, but you give up one for the other. I personally like to have awesome battery usage until I'm out and about and really need to use my phone.
I'd recommend you call T-Mobile customer service and have them diagnose the problems you are having and issue a replacement if necessary.
Based on my experience, battery life is excellent, probably the best I've seen in any smartphone in this category. Battery usually last easily through the day with heavy use, including:
- having 3G on all the time (and frequently switching to edge and back)
- 2 email accounts using push (gmail and exchange)
- gps on all the time
- google latitude running all the time
- facebook and twitter sync'ing every hour
- fancy widget sync'ing every two hours
- Newsroom harvesting 12 news sites in the background
- occasional picture (3 or 4) a day
- web browsing and searching
- xda app for reading and replying to this forum.
- bluetooth is always on
- wifi is on from 8 pm on.
I charge the phone through the night, unplug it at 8 am, return home at 8 pm and put it to charge around 11 pm, with still 50%. Brightness is set to auto. Phone is not rooted or modified in any way.
You bought a high end phone that should perform as such. You are supposed to get the most out of your phone, not turn off its features. I wouldn't listen to those who claim you should turn off everything and dim the screen. What's next, not using the phone to preserve batteries?
That's just my two cents.

Since the previous thread on battery life was merged with other threads on totally different topics, I've opened this thread as a place to share tips and experience regarding battery life. I've little time the coming 48 hours, but I will update this thread and make a collection of tips to improve battery life!
So I've taken some measurements to be able to give a more objective analysis!
I've used OSMonitor Goto menu/options/filter (dmesg) Tag filter [D:BATT] for battery readings The I= the battery drain in mAh.
I also used signal strenght info from settings/about phone/network. I used Extended Controls to keep my screen on during the test and control data etc.
I want to use these results as a reference to determine "normal battery drain" and to determine how different variables affect battery life. It would be best to test this on "out of the box setup' to eleminate influence from other aps. I didn't want to hard reset so I guess I've sinned against science. Another variable I've not eliminated is the amount of RAM being used, and this could be important. I'm not perfect
To compare results it would be best to perform test the same as I did. If anyone has a better idea for a test please say so! It would be perfect if some devoloper could make an app that does al these test automaticaly! It would be a great benchmarking tool!
Results so far:
*Standby
3 mAh (on G, data off)
*Screen Brightness
Screen brightness 0% : ~82 mAh (airplane mode on, everything turned off)
Screen brightness 100%: ~200 (idem)
To compare with brightness 0% my Old Touch pro uses 63 mAh with its tiny screen
(Airplane mode, Brightness 0%)
275 MB ram Free: 75-80 mAh
185 MB ram Free: 75-80 mAh
*Network and GPS
All with 0% brightness
G (GSM only): 82 mAh (data off, everything off) - 83db 15 ASU
3G (GSM/ WCDMA Auto): 85 (data Off, eveything off) -85db 13 ASU
Wifi Connected (Wireless G, Full Signal strength, router in the same room) : 150 (sync off, background data off, everything off)
GPS: 125 (GPS Test, airplane mode, everthing off)
*Gaming
Asphalt 5: 310 (airplane mode, everthing off)
Draw your own conclusions! To be continued!

Funny i was looking for the old thread! Jus to put a note on it 11 hours since unplugged. Hasnt past 50% battery life yet. Had wifi on all day with hourly sync. Using this morning for XDA forums viewing for about 1 hour. Some bluetooth and as it stands the battery thing shows this.
Display 60%
Android System 15%
Android OS 12%
Cell Standby 6%
Phone idle 5%
Wifi 2%
Note i dont have 3g turned on yet as my provider hasnt given me the internet add on yet.
Well it's now at the stage where I've had my phone for a week, so the battery has had a few good cycles and should have settled down.
I'm still looking for the elusive whole day without a top up charge, doing the things I used to do on my hero.
Things I'm currently trying: Syncing facebook and other non essential things (to me) once a day, 2g only, and running Juicedefender. I also have screen brightness set manually to a lowish level, and have stopped vibration feedback on the keyboard....
Will see what tomorrow brings.

I stopped vibration feedback after day one and have had no problems with battery since, I had completely forgotten about that though. I have a feeling you will be smiling tomorrow. If you think about it having to provide constant stabs of electricity to start a motor all the time must be a huge drain.

That's what I'm thinking. I would send 100+ Google talk messages a day. All that tapping and vibrating must eat the battery a bit.

I've disabled it for the on screen keyboard, is there any other place it needs to be disabled? Like for the Home keys at the bottom?
oddly there is another vibrate option under sound settings, right at the bottom there is an option for Vibrate Feedback when pressing onscreen buttons.
Hello all,
Trying to find some info about some behaviour my Iconia has.
I love my device. Way more capable than my wife's Ipad and all that. There's only one thing that irks me: battery drain while the device is idle.
I also have a B&N Nook 1st gen (for books) and an EVO 4G. I leave and use the Iconia mostly at home, close to the WiFi. I'll take it out for long trips and such, but it stays close. I have it set up so that the WiFi antenna turns off when the screen does. Low brightness on the screen, will only charge the battery when it's low enough to charge, etc. It stills drains close to 6-8% if I leave it alone a couple of hours.
Earlier today I rooted the device and use Bloatware Freeze to freeze some stuff. Eventually I'll get rid of some of the gunk the tablet has installed. I want to figure out how to shorten that gap. It doesn't make a whole lot of sense to me that the tablet left alone consumes 8% of battery charge! I mean, if nothing can be done then so be it, I'll learn to live with it.
For my money I would bet that there is something hidden in the Iconia's OS build that thinks it is a 3G/4G device. Now, I'm wondering what would happen if I were to take the next (logical) step and put another ROM in it. Would this make a difference? If I can make the battery drain stop at 5% or less, that would make this perfect.
Thx!

I leave my device with airplane mode checked, and then re-check wifi (as airplane mode will initially turn off your wifi). I get no strange programs showing up in battery usage now.
Will certainly try...
I'll try this next time I head out. Will leave her in Airplane Mode and will check the battery level when I come back.
I did disable the GPS and all location settings. I do not need it to know where I am, since I have the EVO for that.

Right on, let us know if that helps ya out
Well I'm glad I came across this. I didn't even think about leaving the GPS on and consuming battery. Also, where did you adjust for your wifi to turn off when the screen goes off?
EDIT: Nevermind, I found it.
I am developing an app that uses bluetooth and I noticed that if I leave bt on my tab will go dead in 2 days, if I turn it off it can stay idle for several days before needing a charge. I leave the wifi on all the time.

Wow I don't even have 8% drain with Wifi on all the time. There maybe something else in the mix. Most of my drain is the screen as I set it to auto and in my home it ramps up brightness most of the time. Is it possible you have a rogue app? Have you tested the tablet 'fresh', ie: after a factory reset with 1 google profile set up?

This is interesting, on 3.01 & 3.1 I've had zero drain with screen off w/up to 16 hrs. Settings : Wi-Fi disconnect policy never when plugged in, location & security use wireless networks on & gps on. Airplane mode , always off. I can't understand why you folks are having these problems. Hope we find out. Oh & by the way that's not charging.
Forgot to mention I use Juice Defender.
Update
Well, after much tweaking I think I'm somewhere where I feel comfortable. As a disclaimer I don't take the Iconia with me on my daily commute. Again I take my EVO and my Nook with me. The tablet spends the entire time I'm out in the office at home, unused.
I disabled all screen animations and I'm using the tablet on the lowest brightness setting.
I disabled the GPS and all location-related settings.
I rooted the tablet and am using Bloat Freeze to freeze/disable some of the Acer 'junk'.
I put the table in Airplane mode before heading out.
Last night when I went to bed I didn't use it (I was reading a very good book and I did not use the tablet to watch any of my shows). So I put it in airplane mode after I played with the new Google Music app (Impressive!). I went to bed around 11:00 and woke up at 5:00. In this span of time, battery went down by 1%.
Used it this morning to tweet, check a couple of websites, email. Was @ 71% at 7:00AM. Came back close to 7:00PM. Battery was at 67%. Right now (8:50 EDT) it's at 1d 19h 55m on battery @ 59% charge. Heavy usage of TweetCaster, TuneIn Radio, Browser, Market, &c.
Mind you, it was not used for close to 8-9 hours or more. If I were to take it with me the consumption would be more, but then I would probably use Airplane mode when it was not in use. Besides, I can't use it at work b/c the wireless is not compatible.
I'll keep doing some research, but I'm comfortable. I accept the fact that it will drain regardless, since the OS is up. The previous consumption was too much, and I think I can live within the 2% - 4% consumption rate. If it can go down to 1%, though, that would be even better.
Any other ideas welcome.
beautiful Widgets comes with a widget to disable/enable wifi like we're all used to on our phones.
I loaded prime 9.3 today because I wanted to try a 3.2 rom (for GPS and sd-card reasons). On that rom I noticed the 3g settings were visible until I added the line "ro.carrier=wifi-only" to build prop. I was able to see cell standby show up in batt usage.
Not sure if you guys knew it or not but under battery usage you can click on the graph to see a graphical depiction of what hardware used the battery when. If GPS was active when it shouldn't have been you'll see it there.
Interesting...
Are you suggesting that the 3g apk is active on the 3.1 image? I posted this question to a developer in Market that has an app that kills this on the Iconia. Maybe that's the other 2% - 4% I can kill.
Prime is a 3.2 rom. You could try adding that line and rebooting though.
To the stock 3.1 image? Interesting. Any instructions?
You'll need an app like root explorer that will let you mount the /system partition as read/writeable. In the /system directory there will be a build.prop file that you can open with a text editor (root explorer has this feature built in). You'll see many "ro.xxx" lines. At the end of the first group you'll just need to add the line "ro.carrier=wifi-only" without the quotes. Save and exit the file. Reboot tablet. On reboot, it will read the values in build.prop.
On the prime 3.2 rom, the settings for mobile networks are visible without that line added to build prop. I was actually seeing cell standby in the battery usage list. I never saw that on the stock rom. I use a toggle button for the wifi to quickly turn it on/off from the home screen and that keeps wifi from using any battery while sleeping..
I really doubt that GPS is the culprit in your case. Did you click on the battery usage graph to see what hardware was using the battery during the period of sleep?
Also remember
The % charge that the system reports is not always a very accurate indication of how much charge your system actually has - what matters is up time and how long you can go between charges.
Airplane mode is your friend - no real need to disable animation (has nothing to do with idle charge) - the only thing I do is enable airplane mode when away from charger and not using my tab - some of the drain you are reporting could be due to your system scanning for open hotspots.
Also remember all it takes is one poorly coded app to totally screw your battery over - as you are rooted, quite easy to check for apps that relaunch themselves even after closed, apps that want to phone home every 60 seconds - etc.
Would highly recommend you take a close look at any non-stock apps that you have installed.
For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...
Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
