Hi guys! It's been a long time since I posted on the TFP forums.
Recently I noticed that the battery life of my TFP is not as good as I wished. DON'T misunderstand. I think that the battery life is pretty good while using it. Though I never measured it, I think I get at least 5-6 hrs (may be more) when I use it. BUT, the standby time is low and that is what bothers me. I get 2 to 2.5 days of standby time. So, if I charge it to 100% today and leave it aside, it will get discharged completely in about 2.5 days. But my iPod touch gets discharged in may be a week, if I don't use it often and I heard that the case is similar with the iPad (it too gets about a week's worth of standby time).
I really want to extend my TFP's standby battery life. It is a huge disappointment when I find out on Monday morning that my TFP is discharged since the battery drained completely over the weekend. My Droid Incredible 2 does a better job by idling the processor at the lowest freq. (245 MHz) when screen is off. And this translates to great standby time. Does the TFP not do that? Can I install an app that can do this for me?
Other issue is with WiFi hogging the battery as shown in the pictures below? Can I fix this? These are my 2 queries with regard to battery life.
Thanks in advance!

Have you tried changing your wifi setting to disconnect wifi during sleep (standby)? That seemed to help mine. My wifi is a battery hog too.
Go to settings > Asus Customized setting > (bottom) Disconnect Network During Sleep

And... go to accounts%sync and turn off background data traffic...
If you are not using your prime u should turn off wifi and gps...
....and to add to all that above, why not actually turn it off when not in use.
I turn mine off when not in use because I know one thing for sure - Batteries die out faster the more charge/discharge cycles they go through.
Some tips to improve battery life span & keep them healthy -
Never let battery discharge below 4-5%
Never do charging until level drops to 5%.
When leaving the tablet unused for a couple of days/weeks, do a full charge before leaving it.
Do not keep the battery in continuous charge for more than 8 hours.
Hope this will help you in long run.

I actually do that. But still it doesn't turn the wifi off immediately after I sleep the TFP. I wish there was a profile manager for the tablets as I could easily do all of this as I do on my phone.

The idea of turning the tablet off is not what I want to do. I may be okay to do that on a weekend, but during the week I would like to have it on as I want to he able to use it immediately without waiting for it to turn on. Moreover, since competing devices and even my phone can manage to get better standby time, I am trying to improve its standby time.
I will try the profile manager I have on my phone. Also, I will try a CPU app that will put my TFP in the lowest MHz possible. Any suggestions for a good CPU app for this?

Thank you. This may help me a lot! It is interesting that even after choosing "disconnect network during sleep" the network doesn't disconnect immediately. Also, it still uses a lot of battery. Hopefully this will help.
the answers you seek are in general section. I already posted it up in the thread called .21 wifi battery drain. all my recent posts in that thread details what you can do and what's going on in your tablet. always remwber though, wifi will always report being the biggest battery drainer. the battery usage reporting in prime is flawed. you meed to use an app called Better Battery Stats. its free and here in xda. check out that other thread I mentioned. it has a bunch of things you can do n look for.

I wanted to see just how good smart actions work over night, so I charged it to 100% (dropping to 99% immediately) and I have battery extender used to turn off basically everything, no data, wifi, sync, bluetooth after a couple minutes of inactivity and screen off. At 10:22pm power was pulled and phone at 99%. At 7am this morning it was sitting at 95%. Thats pretty damn good! Granted, everything was off, but who needs them on while you are a sleep?
How long have you had the RAZR? I did generally the same thing my first night with it, and the next morning I had 5%

Release day,...Nov 11th. 95% over night?!? Thats insane! Your sure everything is set to off? My Battery Extender Triggers: Display off, no movement, timeframe is made as an all day event, Actions: GPS off, Background sync disabled, cell data disabled, and, bluetooth was on, but will change that.

Somehow, some way, you are doing it wrong...
The RAZR's battery in the first few days of life is full on crazy. Don't even start thinking about measuring your battery usage until a week in with full charge and discharge cycles. Do your best to kill it everyday and make sure you charge it full. You will see over time that it becomes harder and harder to kill.

Agreed. You can't judge any phone's battery within the first week, let alone the first day. After its initial startup, it takes a few days for everything to settle in and play well together. My first day of battery usage was NASTY, but since then (got it exactly a week ago) it has really been amazing!

if there's no data, no sync, then of course you'll get great battery life...
You would think but my Thunderbolt would still lose 10% over night.
I've had my RAZR for 2.5 weeks, and made sure to fully drain and charge it each time. I still cannot get over 10 hours of life with little to no use during the day. (couple texts, no calls, fb at lunch break, check e-mail personal and corporate a few times an hour) I've tried the Battery Extender smart actions, lowered brightness to lowest setting, disabled 4G, set dark background, set auto-end tasks after 2 min, and ran battery callibrator.
Meanwhile, my coworkers with the same phone are getting 21 hours on their phones with moderate use including several phone calls and constant texting.
Not sure what I can do from here to get better battery life.
Heres a screen shot of my battery usage so far. Sitting at 80% right now.

use juicedefender beta, it has its own setcpu, so set screen sleep to 300mhzmin max300mhz, disable data donnection + change to 2g mode when screen is off, auto data connection on to 3g for apps you want to choose, e.g. browser, online radio. then turn off 3g data, switch back to 2g on screen sleep.
my battery drains 1 - 2 % overnight when im sleeping (9hours)
i only wish i didnt undersetimate juicedefender, after finally playing around wiht it, i must say every android user must have juicedefender, else your not getting the most out of ur battery, if u want EVEN more, install advancted task killer pro (and kill the trouble some apps, make sure not to kill the ones that constantly restart, it will actually drain ur battery since it gets killed, then starts, then kills)
I'm getting about 11 hours of battery. And its been 3 days. Still calibrating it tho, will keeep u posted.
I want to conduct a little tiny experiment. I want to see if having "In Pocket Detection" enabled under settings ---> display causes this horrible battery drain.
So what you can do is reply back with with a little data. I don't want a full post,just a few words.
The first word will be yes or no. Yes meaning the setting is enabled on your phone, no meaning its disabled.
Next, indicate good or bad. Good meaning YOU think battery life on your razr is acceptable, bad unacceptable.
Next, enter a number in hours on average your phone lasts on a full charge. If you don't know leave it blank. If you entered a number then post with that if you are a light, moderate or heavy user.
Last, put down "4G" if you leave yours on, "3G" if you turn off 4G, and "hybrid" if you go back and forth.
I'll do mine as a template. I'll compile the data if there is enough on a spreadsheet and see if that pocket detection is an issue.
No - Good - 16 - Moderate - 3g

hi everyone this is my first thread and i am glad to be here
i have a question
i am thinking of buying the samsung galaxy s3 but i read that some people are complaining about the signal and the battery and i wanted to know is an issue in the carrier or from the phone itself ? and is it a problem on all of the samsung galaxy s3 phones ?
Well this S3 is the smartphone with the longest battery life I ever got.
I would say it is twice the nexus one or LG X2 I had before and 4 times my older Basic Galaxy.
Reception is very good and Wifi is also the best I have ever seen.
Battery life is fantastic and signal strength is also fantastic (both better than any other android phone I've ever owned). I've found wifi strength can be a bit lacking but not to the point where it becomes a problem.
Same as above, no signal or battery issues. Battery is very long-lasting.
Only issue I've had so far was a wakelock keeping the phone awake all night and draining it, but that can happen on any device.
Good reception and battery life. Gotta be happy with 6 hours screen time.

very impresive man..btw my s3 doesnt have any signal or battery issues
i think my have battery problem, it don even last me a day and i dont even use it that much and also mine gets very hot when charging it
Believe me after coming from a LG optimus 3D i would say the battery life is awesome. LG optimus 3d battery life with heavy usage 3 hours no usage 5. S3 with heavy usage 15 hours or more, no usage i have no idea last time i left it on idle to check it was almost 2 days..
That is comparing a dual core to a quad core phone the battery is simply amazing and the signal hasn't dropped for me at all it is excellent..
I'm having battery issues. Cell standby seems to use a crap load of battery for seemingly no reason.
This pic is just over night. I went to bed with 100% battery and woke up with these battery stats:
Battery life is not a issue in this mobile..its awesome..even signal strength is also fine so till now no probs at all ..
So I'm having major battery issues. After 2 hours of light use my battery is down to 84%. Tried to post screen shots of the battery usage but can't upload .png file. Basically the android system is consuming almost 90% of the battery. After 4 hours it is almost half dead and by 8 hours less than 20% left. Very frustrating. Power saving mode is on.
Ok so i was able to attach an image showing a screenshot I took yesterday showing the terrible battery life.

My problem exactly. Cell standby is giving my battery a hard time. On Voodafone now.
IMO High Cell standby power drains suggests your signal is weak?? chaning your wireless network settings may help Eg: 4G on or off, roaming etc. High Android system drains suggest unnecessary systems always running. I would try turning off any unused apps, GPS, etc & lowering display brightness. I think I'm going to get this phone tomorrow.

Is anyone else finding it extremely difficult to get through the day without struggling to keep your SIII alive? I thought the battery life was supposed to be superior to its predecessors? I'm a first time Android user but I did not think I would have to lower my brightness all the way and constantly monitor my devices battery life.
do you have some dumbass apps draining your battery?
i found my culprit and it's Friendcaster without even turn the notification on
get Badass battery monitor to find it or just use the one in setting
I'm finding the battery life is great, and lasts a whole day with no problems
It really depends on what do on your phone.
Try posting a screenshot of your battery stats. Android has an inbuilt monitor with each app and its usage being displayed. Easy method to spot a drain.
I just downloaded that in addition to my other app but there doesn't seem to be anything out of the ordinary that seems to be killing my battery. Most of it is coming from my screen but I keep at it 25% brightness the whole time. Super odd
I usually get around 16 hours of standby and at least 4 hours or more of screen time.
You should try Watchdog Task Manager. It will be able to tell you if an app is running and using more processes than it should. Also I've never used badass battery stats, but better battery stats will tell you if anything is holding a wakelock. It is free for XDA members so you don't have to buy it on the market. Just search for it

On saturday I drove for 4 hours streaming music via bluetooth to my car. Used navigation for about 40 minutes with the screen on the whole time. Took a few calls, sent a few sms's. Read a few forums using data. Got home that night with about 40% left. That'll do me.
Maybe I'm just freaking out about the whole battery situation? I just expected it to be a lot longer and a lot better. I constantly worry if I'll be able to make past 10PM when I start my day at 7AM.
On wifi with little to no voice signal that cuts out frequently, I might get seven hours of screen on time today D:

I'm getting huge drain from Cell Standby.
It'll lose 30% overnight. I keep checking for a software update. It's got to be the modem.
I'm holding off on rooting and custom ROMS until I know for sure this is fixable in firmware.
My phone's on LE6 and is from Thailand.
I see that you have poor signal reception
maybe that's why
last time I went underground, just 5 mins of standby it took away 10% of my battery
when it searches for signal it drains a lot
you could also try to disable auto search for network
go to setting>more settings > network operators and select it manually

Super idea ) i've done that today. All seemed good. 2,5 % awake is fine
I see that the major cause of battery usage is the WiFi, exactly like it was on WW28, the worrying thing is that I also spotted that during the night, the Prime lost 2%, even though all stuff was turned off with the Prime in sleep
All Sync, WiFi and all the things that could use WiFi are turned off and all "checks" are set in settings that could be checked/unchecked.
On WW28 and using the modded prop, I never lost a % during night.. so maybe the only way to have it working good again is to have a new prop suitable for the JB (I asked in the proper thread in Dev. forum)
Any other experiencing battery drain with JB? And especially a higher WiFi battery usage again?

The difference might be explained by the fact that if you use more "brightness" than I do, then the percentage of what screen and wifi use may vary.
My screen brightness is 20% then my value for screen is lower than yours and the battery higher, because that's the proportional values.. I think.
That's the best part, the tablet is usually 1-25% brightness the majority of the time. Prior to JB, similar usage would have wifi taking close to or above 2-1 ratio. <3 this update
I've found that I've got about 5% increase in battery life. There are new Power Saver section in settings so you might want to mess with those and see if it helps. From what I've seen it's really only to turn stuff off at a user defined power %. Still, check it out.

Thanks, but I did that.
I found a bug too.
When you change the power settings from the quick settings window in the "desktop", the changes are not recognized in the "power setting" you refer too, you have also to change there.
So if I choose balanced one place I have to do the same in the other too.
I see only that the WiFi is much faster at start when waking up from standby, but I think there is something wrong in these power settings.
I never lost 2-3% at night when the Prime was on WW28... and the battery/WiFi seems to drain faster now..
Just let things settle. These things takes time after updates. Its too early for any accurate readings anyways.

Remember that we do not use all same settings, and/or use devices same way. Making a comparison is only possible on the same device and the same setup/use.
I am happy that you are seeing improvements.
I will see in a week what is the result for me.
How could I imagine they would ever get it straight
Bad, it's worse than on .21.

Aye, as far as I can notice it's draining a tiny bit quicker. I keep mine at max brightness IPS+ (except for late at night every now and again) but don't get more than an hour or two's use a day on average. Usually go anywhere from three to six days without charging, depending on how forgetful I am with turning WiFi off.
I can't factory reset like you until there's a new root method, but also like you I factory reset and restored only specific apps' data so the update would go as smoothly as possible. To no avail lol, but oh well. I'll give some more in-depth info as I have time to.

U should reset ur phone. G2 battery is very awesome. I turn on everything 3g, WiFi, sync, Facebook, viber, ... And I use my phone to read news whenever I have time, so my screen time on of my phone one day is usually 4 hours. Everyday I get home with approx 40% of battery. But one thing I recommend u is u should buy the app lux auto brightness replace for stock auto brightness. I was really surprise after I installed that app, it save for my about one hour screen time.

Download "Better Battery Stats" https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
Take a look at the wakelocks, alarms and see what is keeping your phone awake.
Also , posting a screenshot of your battery life graph would be beneficial.
Cheers !
Edit: Agree with quachhanthanh about Lux Auto Brightness. Totally worth the money , even though the free app does its job admirably.
Ah good idea with lux auto brightness.
I will test this too.
The stock auto brightness never works good on my phone.

Ah ok thank you , could have known that myself
It really helps to know the stats to start. A rogue app or service can cause a lot of issues. I had a contact sync issue that drained my battery quickly. Found and fixed.
I use greenify(really good for battery life) and also under google settings, I mean the app you have called google settings, uncheck all those things you dont need including under Android Device Manager -> Remotely locate this device. I disabled alot of things in there. If you need to leave wifi on you can also change your wifi scan intervals to like 360 in the build.prop. Thats just for starters.
Great battery here!
As has been said, a battery graph will help out a great deal. If you have a rogue app, it will show a higher percentage of usage than other similar apps. If services really high, you might want to take a look at exactly which services are running. Be sure to always disable any you don't actually use. Also make sure your screen is set to turn off quickly, or use that nifty knock off feature. One last thing, if you are in a spotty coverage area, your radio will broadcast at maximum power trying to find a tower. That searching will kill any battery.

I'm getting horrible battery life.. About 2.5 hours screen time with 45% left. Screen has only used 20% of the battery.. its mostly being used up by Android System (33%) and Android OS(13%). I've got wakelock detector installed and its saying most of the time my phone is in deep sleep... God know's what's the issue.
P.S: I'm even using DS Battery Saver to force deep sleep... I really don't know why the OS and system are using so much battery!
P.S: Using better battery stats, it seems I'm having the activity manager causing wakelocks and the alarm rtc and powermanager service causing wakelocks... anyone has any idea how to stop this?

Depends on what you do with the phone. I can drop 20% in like 3hrs easily using spotify alone.
At the moment im at 37h 12m with 3h 8m screen on. Im at 40%.
Here are my stats. I wonder why there's such a variance between different phones. Do LG source batteries from many different manufacturers? Maybe they don't do enough QA on the batteries? Battery life for me isn't terrible compared to other Android phones I've used (many won't even last a day), but I definitely need to charge it every night.

Useless, can't see your app usage.
I recommend posting in the comparative battery analysis thread.
Make sure you post all screen shots otherwise OP will be on your case.
