Wifi Battery Drain - Asus Eee Pad Transformer Prime

Has anyone else noticed that since we can see battery stats now with the .21 update wifi is eating most of the battery even more than the display.

Yea, battery is draining quicker compared to last Firmware. You can turn off WIFI during idle stage.. however, yea.. it's annoying.

yeah, i noticed this too. i even have wifi to shut off when sleeping and its still consuming 55% of the battery.

Maybe they boosted up the wifi signal strength a lot to compensate for the infamous poor wifi signal with battery drainage as a consequence.

That is what I posted in the other thread. Only thing I can think of that makes sense.

Same here. My wifi has used 79% of my battery since last charge.

Can you point us to that other thread so we're not fragmented all over the boards?

The other thread was about the update generally:

Are you guys sure the stats are 100% accurate? I dont think that wifi actually sucks more juice than the display. Its the same on my Prime but its possible that the stats just arent that accurate. I have wifi set to disable when in sleep mode so i really dont think it makes sense that it takes up more than the display even in that setting.
Could be wrong though^^ My batterylife so far isnt really different than before the update - at least it doesnt feel different.

my battery life is still the same, which is great. wifi being a battery drainer is nothing new. top 2 battery drainers isbthe display(how high you have it) and wifi. I have my wifi on 24/7. never cut it off and I still get great battery life. I tried that cutting wifi off during sleep setting but I hate it. it always takes the wifi connection a little will to come back connected once display OS activated again. so I just leave it on. another thing to check also is to cut your background sync times down. you don't need email be checked and sync every 5 mins. cut sync off on anything you know you don't use much. saw goes for app notifications also. I got tired of my Facebook going off all the time, so I cut it off. it'll just update when I open the app up. or doing a manual refresh.

WiFi drain seems to be a lot higher since the update.
I got slightly over 5 hours of surfing and messing around undocked last night. WiFi used over 65% of the CPU.
Sure I was getting closer to 8 hours before.

I have noticed a huge difference. Last week my prime would only lose 2% battery over night. I updated and haven't changed any settings. Now it drops roughly 40% over night... I'm not happy to say the least. I'll try turning wifi off tonight and compare the 2 settings.
(By the way, I'm rooted and stock everything else)

Glad I am not the only one. I just got my TP a week ago and updated to .21 and sure notice that battery life has been awful. Using it for web browsing, loses 10% in about 40 minutes. And turned off seems to drain the battery as well, more than before the update.

I do not have drain over night.
I charged it full, and after 9 hours in stand by, battery was 99%
BUT the BlueTooth draines the battery when the Prime is in use.
The settings suggest to turn it off, if you do not need it.
21WW seems fine for me about the battery usage otherwise.
Do not expect the usage they were talking about in the specs.. it's not true!

WiFi analyzer shows no difference in signal strenght, and my Prime has been RMAed at ASUS and had changed parts (WIFI/BT issue), it did not help either.

Hey everyone,
I tried searching on here but couldn't find anything similar. I thought I'd post here as its battery related.
For a start, my Prime is completely stock with the .21 firmware. Earlier today I noticed my Prime battery monitor hadn't gone lower than 93% for AGES! When I went into Settings - Battery, it said 93% Unknown. I obviously guessed it was a lot lower than that as I had used it a fair bit most of the day. I was using it about 2 hours ago and it suddenly switched off. I guessed it had run flat so I put it on charge. I've just tried to switch it on and nothing!!! It's been charging for a good 2 hours or so.
Any ideas??? I've had it less than 2 weeks!!! :-(
Thanks in advance.

cold boot. hold down the power button and the volume down button until you see the text on the screen, then choose boot without wiping your data.

Since last update I get more than 20% / hour of battery drain doing web browsing at 50% screen brightness ... it was way better from what I remember when I was on .11 and .15 ...
Tried cold booting, will see if that makes a difference ...

Well after charging all night it did switch on as normal again. But today the battery has stopped at 93% again. Going into Settings - Battery, its says 93% Unknown again. :-(

Sounds like your batterystats.bin file is corrupt. If you are rooted then navigate to /data/system/ and delete batterystats.bin
Reboot and Android will create a new version of this file and hopefully it will display stats correctly.

I am running .21 in power save mode. I have noticed the following. Using OS Monitor I found that "System" process was using 65%+ CPU resource all the time. So I turned off/stopped as many things that I could no effect..accept..un-mounting my SD card.
Once I un-mounted my SD card the "system" process time dropped to less than 10%.
Since then my battery has only dropped 7 points in 14 hours..based on my "Battery indicator" app.
So why would my SD card eat up battery life by consuming CPU time???

Battery drains faster than usual

I have noticed my battery sucks lately. I know the battery isn't the greatest but I was able to get easily a day of use out if it. Now I can barely go a day. I purchased beautiful Widgets, battery indicator and xda app all last week And it seems after that is when my battery went to **** .I used launcher pro for a bit too but started having lag problems so I removed that. Today I uninstalled beautiful Widgets. I'm on wifi and in airplane mode. As I'm typing this I've lost %2 already. Wtf is going on? I have GPS Bluetooth and usually wifi off. I have use only 2G networks, sync only gmail and screen manually set and set to low 30sec TO.
Any suggestions?

Sounds like way more than that. I can certainly type a couple paragraphs before my % drops at all. You sure haven't installed something else? If not you could have a defect.? Possibly return it and get a new one?

Quick question, which ROM are you running? Ever since I switched over to leaked JI2, every couple days I notice that after running one of a few apps, the CPU just seems to go into overdrive. The phone gets really warm and the battery drains ridiculously fast. So fast that even plugging into my car charger won't charge the phone, even on idle. If I reboot, the phone cools down and the battery drain goes back to its normal, slow self.
I haven't narrowed it down to any specific app yet, but it seems to be either, Foursquare, Great Land Grab, or Bubble Blast.
Foursquare I have, I don't remember when I installed it. I am actually just running stock TW.

I get 15hrs... I am not ROOTED! I did the drain battery life process twice. This is with moderate usage. I am planning to do the drain battery process once a month cuz I hear it helps with battery life. Possible that u install something that's killing your battery.
Solution do the master reset if that doesn't help then it can be the battery is no good. I know that this is with the stock rom. If u are using another rom that's maybe the problem. U can try switchig roms to see if this is the problem. I hope this information has been helpful.
Does the master reset remove everything ? I have all my pics/videos on my phone meM. I have music and avatar on SD.

I have the same issue and i run system app n it doesn't show anything abnormal running. Its awfully frustrating i went from being good for 18hours to being in the red after 12 hours. I dropped 2% just writing this. I have only 84% left after 1.5hours this morning...and I have no service during my 1hour commute so I haven't used it. Standby is killing my battery.

It seems as though it drains faster in standby with nothing running. I removed FourSquare last night and have nothing running as far as widgets. I'm going to reboot and see. I've had it unplugged since 7am this morning, after a little over an hour I lost 2%.. not that bad I guess..

I've had this happen a few times. For me, it's usually because my battery status gets thrown off somehow. The phone would read that I have 55% battery life left, but it really only is at 25 or 30% and it always feels like it's draining fast. I usually turn off the phone, pull the battery out for a few seconds and then put it back it. When I turn on the phone the battery percentage is corrected and the phones seems to be back to normal battery use. I don't know why this happens.

This was suddenly happening to me today -- my battery started draining very quickly, mostly on standby (I usually have quite good battery life). No new or unusual apps installed in the past week (I don't use Foursquare).
I gave it a power-down/battery pull; no adjustment in the % as described in the post above, but it seems to be draining more normally now. Weird....

Same thing happens to me every couple days. Rebooting the phone fixes it every single time though, so it's not a big deal if I catch it in time. If I didn't catch it, I'd estimate my phone would be drained (even in standby) within 4 hours or so.

Same here, I rebooted after removing FS and some other apps/touitur and got 1day 13hrs on the next charge with pretty moderate use. So whatever it was, it's gone now. If it was FS hopefully it's fixed soon.
Had a similar experience, with battery % entering freefall every time I turned the phone on. Two things helped:
1. I did the drain cycle. Drain the battery completely till it shuts off and charge it to full while off. This does not 'fromat/form' the battery in any way it just helps the phone to calibrate the meter.
2. I uninstalled few apps that I suspected were draining the battery.
I advise you install JuicePlotter and see the graph of battery drain. You'll be able to tell if the phone is entering standby or not. Thanks to some culprit apps (still figuring out what it was exactly) my phone was not entering standby at all hence the crap battery life.

[Q]Phone Idle 70%??? really? why?

2.3.4 eclipse 1.3 in my situation, so I don't understand what causes such ridiculous Phone Idle percentages, is it from ram being abused, an unreliable connection, android hating?
(everything else is commonly below 10%)
wifi is typically left disabled, and i keep it slightly underclocked
what else android, what else!
I swear...the phone never truly goes into sleep mode...it stays awake for large chunks of time doing god knows what...every other phones battery usage graph I have compared it to looks completely different and only has small tiny lines of awake time...mostly when screen on...my x2 shows huge chunks awake when the screen hasn't even been turned on and data disabled for over 4hrs...I don't understand it. Killing my battery
it's a kernel bug, reboot yer phone immediately after unplugging it, every time. or downgrade to froyo (i got my absolute best battery life from froyo

Me?
Yeah I have been doing that since that fix was posted...it helps with life and awake times but it is still horrific compared to other phones...whether I reboot from power menu..power of/on...or whatever....it needs to be fixed...I don't understand why it does this...im about to delete the things that allow it to communicate with moto databases lol...
compare the battery capacity of other phones, most other phones come with at LEAST an 1800mAH battery, this thing is 1500mAH if you're lucky, couple that with 2.3.4's reporting bug and you end up thinking you're going dead much faster than you actually are.
I spend over half my days hovering at 15% or lower according to the phone, but I've also realized that it lies, alot... like my ex.
what does that actually do? =o
like what if you reboot a couple hours after unplugging?
... Christ what was 2.3.4 for if they didn't even get some of this stuff cleaned up
it prevents the idle process from "running away" when you plug it in it essentially disables the idle process, when it goes to re-enable it, it never stops, it takes up CPU cycles and burns the battery down for no reason and it will do it from the moment you unplug your charger/USB cable until you restart the phone.
why? beats me.
I thought you no longer needed to reboot after unplugging on 2.3.4? I did it every morning on 2.3.3, but stopped after updating to .4
I'm confused with this. Wouldn't a phone idle of 70% mean you the phone has been sitting there not being used?
As far as sleep, i use a cpu monitoring app from time to time and it shows my phone in "deep sleep" for multiple hrs when I'm not using the phone; my phone idle will show an equal high %, too.
Sent from my DROID X2 using xda premium
that list indicates power consumption. if I reboot my phone in the morning, idle stays around 10-15%, if I don't, that number skyrockets 40-45% and by 5 or 6 pm, I'm hunting for a place to plug in.
my biggest boosts in battery life came from turning on "data saver" disabling "background data", anytime you can make the 3g radio shut off, you're saving TONS of power
I also just upgraded to a BH6X battery, it was the ONLY way I could make it through a full day when I was working in Cheyenne, Wyoming (cell service there, not so great) I also use wifi as much as possible 'cause it seems to draw less current.
battery life and signal strength definitely have a correlation. the less signal you have the quicker that battery dies.
also, "SuperDim" (available on the market) is a HUGE battery saver, not to mention the fact that the automatic light sensor just doesn't make the screen dim enough, ever. I kinda miss the semi transreflective screen in my G1, I never had to crank the brightness way up to see that one in broad daylight, made the colors funny but at least it was legible. but that's the price you pay for pixel density
I've never had bad enough battery life to try Juice Defender but my roommate uses it on his bionic and it does pretty well. His only complaint is having to load facebook or his browser twice to get data to come back on.

I am getting amazing battery life! Coming from a myTouch4G which would last maybe half of the day, its amazing!
I was at 51% when I plugged in my phone today. I have been using it all day and pretty extensively.
No juice defender either...
This is a mysterious problem for me also. I could have phone booted
up full charge everything that load's up is started. I could turn on airplane mode not do anything else for the day. (So No data no phones) And every-time I bring up screen I will see the amount of apps running go's up (ghost apps)
battery down & less & less ram available.

If you manually tell your phone to go to sleep, you have to long-press the power button for like 6 seconds to wake it back up.
This bug happens on multiple Motorola phones (bionic and d3). I know for a fact that this has been brought up multiple times to Motorola thru customer complaints, Motorola feedback program and carrier complaints. But for some reason they don't care or feel its a big issue. For issues like this, I wish they would unlock the bootloader.
I just installed this:

Have just been running it for a little bit but what I can see is that it definitely has an impact on battery life (in the good way). My battery seems to be dropping slower.
Thanks to 0vermind two posts above me.

I cant for the life of me remember but I read somewhere that unchecking the "automatic" setting in "date & time settings" stopped that part from oversyncing and draining battery. I have had mine unchecked for a while and seems to help some. Might be worth a shot. oh I usually 19% +- 1-2% on my phone idle at pretty much all times

That was me in "phone awake" thread.
What it solved for me was the chunks of time phone is awake(when screen has been off) are extremely reduced compared to when the setting is checked.
Only thing is that once in a while(mainly after bootstrapper use or a battery pull) the date/time is messed up. Easily fixed by turning the setting on for 5-15 seconds til it fixes itself and I turn it back off
Ash,
Yea discovered that today when I put in new class 10 16gb sdcard. No worries easy fix like you said super find been using your discovery for a week know working great.

[Q] Terrible battery life on Evo View

I just got the View for my wife to replace her Kindle Fire and it has terrible battery life running HC. I have it in airplane mode and I have tried a number of battery life tips that have worked on all my other Android devices and nothing is working. For instance its been on battery for just under 5 hours and just barely over 1 hour display on and its at 35% right now. I used to have the Flyer and it was pretty decent when it came to battery life but the View is terrible. Am I missing something?
The flyer was wifi only. The view is running a mobile data plan. If you want it to get battery life like the flyer then turn the mobile data off and only use the wifi.
This is what I do with my view and I am usually trying to kill it at the end of the day to charge it. I'm on it constantly throughout the day as well.
My battery life seems fine. I use it off and on throughout the day and I have the Cellular radios on most of the time.

I have been monitoring the battery stats very closely and it doesn't make sense what is causing so much drain. I even have Better Battery Stats installed to monitor partial wake usage and nothing is out of the ordinary. I've never received a device with a bad battery but I'm thinking this might be the first.

i think you did that does not sound normal mine last all day with heavy use i can say i have never had it go all the way down...you may have a bad battery it just doesn't sound like the two i play with in fact one on gb the other on hc and the hc is lasting more....
Aside from a possible bad battery, you might have a corrupted battery stats file. Try clearing the file by deleting it if you have root.
Wait a few days. I think the same thing happened to me. Maybe for the first few days the battery indicator is not very accurate.

We've had it since 1/31 and it hasn't gotten any better. I've been doing some more testing and it seems as though wifi is the culprit. In airplane mode without wifi on it seems fine without use and doesn't drain. With wifi on the battery usage shows a constant drain without any use.
Try out my rom. All my testers and users report much better battery life than the stock rom, and I've got a couple extra things under the hood.

I just picked up a view off of CL. Same problem.. Horrible battery, didn't even last a full day.
People make fun of the ipad, but that 10 hour battery is no joke. This thing, with cell radio off and wifi on, lasts me MAYBE 5 hours, and thats with medium usage.
That's insane.

Now don't just assume all Android tablets are like your experience with the View. I'm confident there is something defective with the one I purchased. I had the Flyer and it would last me a good 7 hours and I currently have the Galaxy Tab which easily gets me over 9 hours of actual use (ie screen on).

Just got my S3, draining battery like a mofo

So I got my GS3 in the mail last night, overnight shipping is an amazing thing. The phone looks and feels great, I'm very pleased with it in all ways imaginable but one....my battery is dropping power like theres no tomorrow.
I left my device to do a full charge over night. Unplugged it when I left for work at 7:45am. It is now 9:35am and my battery went from 100% to 83% with the majority of that time spent in sleep mode. The built in battery monitor was showing my display taking 71% of my battery power....thats insane. I got it so late last night that all I had time to do was setup my sim card and configure the phone with my personal data. I haven't even installed anything yet. All screens are still factory default.
I'm at work currently and just did a full factory reset. Battery usage on display now shows 53% and increasing. I have dropped brightness to nothing and still the display is leeching power. At this point I don't know what to do.

So I got my GS3 in the mail last night, overnight shipping is an amazing thing. The phone looks and feels great, I'm very pleased with it in all ways imaginable but one....my battery is dropping power like theres no tomorrow.
I left my device to do a full charge over night. Unplugged it when I left for work at 7:45am. It is now 9:35am and my battery went from 100% to 83% with the majority of that time spent in sleep mode. The built in battery monitor was showing my display taking 71% of my battery power....thats insane.

What is your actual screen on time?
killing is my business, And business is good.
compared to many of the other battery posts it seems like yours might have a bad one, not sure. That drainage doesn't sound normal but I have no hands-on exp with the phone yet

Yeah I would give it a day or two to stabilize..... use it as much as you can.....I at least can see how you would be concerned, but don't be....it will get better.
You MAY have a bad battery but it is WAY to early to start thinking that.

say thanx to god that u dnt have htc one x.htc one x is battery sucker phone
Any advice on a reliable\trustworthy battery calibrator app?
And yea, I understand I may have got my hands on a (hopefully) rare bad battery. But the display usage seems extreme to me. I suppose that'll be adjusted with calibration though?
Sorry for my noobiness. Prior to receiving this SG3 I was an Iphone4 user with an Asus Transformer TF101 tablet. Got the tablet after the iphone to experience the android OS for the first time, which is what led me to exchange my iphone for a SG3. I have some working knowledge of Android, but strictly from a tablet perspective.
To my knowledge battery calibration on this device is the same as the S2....which means calibration apps a deleting battery stats does not work. The best calibration you can do at that point is to pull the battery for like five minutes and then put it back in.

do you have service at work? if not, that might be the reason
Sent from my SAMSUNG-SGH-I717 using XDA
Ok, I'll do a full charge on the battery then pull it. I'll drop it back in after 5mins and report back if there is any change in the usage display.

Are you using wifi by any chance?
Sent from my GT-I9300 using XDA
Yeah if havent yet run it flat i would pretty much ignore everything the battery stats and status bar tell you.
Sent from my LG-P920 using xda premium
Yes I use wifi. I have little to no use for data plans, so I typically buy my cell phone at full price to eliminate high monthly fees (canada data rates are retarded), and ensure I'm not locked into a contract.
So yes, I always run wifi so when I'm at a location with wifi I get some added functionality.
On or off however, the affect on the drain is not even noticeable.
I'm still continuing my phone charge to 100%. This time I'm using a power outlet rather than a computer usb port. We'll see if things are any different when its done. Currently at 98% and charging.
Well the battery showed 100% at 10:53
Pulled battery and put back in at 10:58
By 11:01 battery% dropped to 98%
Guess all I can do now is try and drain the battery completely and then try another full charge.
edit:
11:25 battery is now 95%

I knew you were using wifi. Look at my topic a little bit below yours. It's called the "Battery Drain almost solved."
It's wifi that is killing your battery. Have it set to turn off when it enters deep sleep. The WiFi is not regulating it's power draw. When your phone sleep wifi stays on like you are downloading something when it should be turning off and sleeping as well.
I'm trying to make this more widely known so Samsung can fix it.
I did see that post before starting my own, which is why I turned wifi off completely to test my own battery issues before posting. But I saw no difference in battery performance. And the display usage still showed 60-70% use of the battery, even with brightness turned low and the screen spending most of its time in sleep
edit:
sigh, now the phone is making look the fool because I decided to test again with wifi turned off and I'm noticing a slight improvement in battery longevity. Display usage still shows a scary 55% of usage even it the screen remains off 90% of the time and I just wake it up to view current battery stats
as far as i remember, a gui of mobiflip has mentioned that you should deactivate the dlna/wifi direct option in the settings of your s3. don't know if this helps
Sent from my Nexus S using XDA
dlna/wifi direct option are off by default and are still off when I went in and checked. S-Beam and NFC are active by default though, so I've now turned those off...will test further
edit:
So currently I'm testing the phone with wifi always on but the sbeam and nfc services disabled. (also, I'm leaving the screen ON and not letting it sleep...so I can actively monitor its progress with screen activity)
edit2:
12:45 85%
12:55 84%
13:05 81%
13:15 79%
13:35 76%
13:45 74%
edit3: (now turning off wifi completely and gps, leaving screen ON still)
13:50 73%
14:00 72%
14:10 70%
14:20 68%
14:30 67%

S3 standby is crap!

Been using s3 abt 2 weeks solid fone but i got one issue battery life on it sucks! funny thing when im using it for the web, video,etc the battery holds up pretty well but its the standby time thts killing it. I charge my fone full everynite wake up next morning and the battery's down to 56% jus on standby!! with nfc off s-voice off just wifi on. Am i only one experiencing this or is this normal?
you have something else going on i lose 2% overnight...try airplane mode see what happens
I think your charger may be broken lol. You charge it every night yet your phone is at 53% when you wake up? Anyway, assuming you sleep 8 hours and that your phone was at 100% that is less than 50% on 8 hours. You probably get 17 hours standby time, not the best but not the worst. Try airplane mode

think you are alone... Yesterday, beach day: From ten o clock with 100% brightness, about 40 minutes surfing with dolphin browser, total in amount 35 minutes facebook, 30 sms, 9 calls all about 2-6 minutes and some recording of the soccer game; the rest of the time the phone was on standby. Coming home with 80% left....
what says your battery settings? what stands by "battery in standby"? How much takes "android system", how many apps are listed in total? Do you have battery save mode on?=> Try to turn it off. Do you have auto brightness? Turn it off, set the display to 40-50% and make a widget on home with settings to 100% so you can read under heavy sun. You are outside the day?=> turn the wifi off....
Tell us more and post your results, the comment that your device is a bucket full of crap is bull**** because the S3 has one of the best battery and settings in smartphone business!...
Greetings,
Snew
My S3 depletes 1-2 % overnight.
This the EUROPEAN variant of the phone?

no-one can give you a legit answer as you haven't bothered to tell us anything about what rom/kernel you are using, what you have installed, whether you have any syncs switched on..
why leave wifi on overnight? thats gives apps the chance to update in the background
have you looked at bbs stats?
fail thread imo
You sleep with your wifi on? what do you expect to happen? Also try rebooting before you go to bed.

Twelve hours standby for me = 1% to 2% drop on stock .

"solid fone"? Are we serious with the spelling? No wonder your having trouble.

now i would like to know how you get that because mine drops from 100% (99%) to 95% in just an hour on 3g but nothing else..
I think you have a defective battery. Mine just drains 2-3% in a 8-10 hour overnight standby.
I hate when people assume something sucks when it's their own doing that's causing the problem.

Stop using Wifi, do not leave it on. Wifi is the culprit.

I still suspect this may be router related though. When I had my crappy Netgear, I would get strange periods of battery drain on my SGS2 when WIFI was left on. That just about all disappeared once I upgraded to an Asus RT-N16 running Tomato, and now, I don't get any drain on my SGS3 as well when I leave WIFI (set to "Always On" under Advanced WIFI Settings) idling.

If mine is full before bed, its 85 percent plus in the morning
You have something that is sucking power, and you need to find it

I too think it's router related. It can possibly be due to Wifi dual banding in some routers that support it. Faster internet with less battery life.
