is it just mine, but under battery consumption it says "mobile network signal" although asus is having some issues saying what is consuming the battery exactly. i went to best buy and looked at the acer iconia one, and to my surprise there the 'mobile network" stuff was consuming the battery. what is up with this? did google forgot to exclude the radio signal stuff that sucks on battery (i saw what mobile network signal did to my notion ink adam). can someone remove it from a rom or something. you guys have any ideas?
Transformer is WiFi only for now but they will have cell network versions as well, just like xoom. Honeycomb must support cell "radio signal stuff" why would google remove it from honeycomb?
I'm curious to know if it's just labelled as mobile network signal.. It's clearly not getting a network signal.. maybe only wifi.

i understand that the transformer is wifi only, but why does it show up. there are no 3G/4G or any other type of cell communication chips on this thing. asus is messed up at telling what exactly is consuming the battery and at what percentage, but mobile network is there on the list and at the top i might add (however accurate that list is). as i mentioned, i looked at the acer iconia and, along with the screen and wifi, mobile network was sucking on the battery.
google should get their act together with this honeycomb os. i would think it should look if there are mobile network chips powered and shut off the feature if nothing is found.
i have a notion ink adam, and having very similar hardware, the software is still gingerbread or whatever, and the mobile network was sucking tons of battery on that one albeit none being there (no mobile network chips present). i am seeing the same issue with the transformer and the iconia
Is there a separate entry in the battery usage stats for the Wi-Fi signal?
No offence, but notion ink adam is a failure all together, I am sorry you spent money on it. That aside, my battery life is great and not even close in comparison to my Samsung Epic 4G which IS using mobile network and drains like crazy - I always have a charged spare since often I don't make it through the day with heavy use. Transformer battery lasts which seems to be forever, and trust me, I have been using it heavily since I got it. So I'd say it is most likely a UI issue rather then the actual draining. If there is no mobile radio hardware... what would be draining battery? Something has to request more juice and hardware is just not there.

i am not saying that the battery is not great. i used it for almost 5 hours and i still have 55% left (i turn it off when i am not using). the same think i am saying about the adam. what what sucking on the battery since the hardware was not there? and, it is not just this one. the acer iconia was doing the same thing. there were three things sucking power: screen, wifi and mobile network. it is very weird.

well, i do not know if i agree with your assertion that the adam is a failure. the thing is virtually unbrickable (asus should have though about this one, i am sure is not hard to implement). the battery does last just as much as the transformer, and it wasn't for the mobile network issues would probably last a whole lot longer. honeycomb is not polished yet, i get that, but youtube and other videos were flying on the adam. by the way, i sold it because i did not like the washed down PQi screen (i was am not and will be reading any books on any tablet, especially outside) . it had full size usb and hdmi so you would not have to spend extra money to buy cables. it did not have the looks i agree but it was functional. i do love the transformer more than anything else, and i am eagerly awaiting to fix honeycomb up this will make a great htpc
I suspect that mobile network is a service process that is eating battery by taking up CPU cycles. Hopefully we can get that service disabled on wifi tablets once source drops.
Yeah... Adam kind of got screwed by distribution problems (And everybody complains about Asus's launch), and Google's decision to limit access to Honeycomb. I still think the hardware of the Adam was brilliant, and would love to see an Adam 2 with a hopefully more mature NI behind it, but for now I need my honeycomb on my transformer.
here is a post in the acer iconia forum that talks about this specific issue. since i have seen it on both, they both have this cell standby things sucking up on battery. you guys look under the battery usage and click on the bar where ti says the time the tablet has been on battery. you will see it there.

i thought the source for the transformer did drop. it can be downloaded from asus' website
I haven't checked recently but last I had heard, that was only the source for the linux kernel, not for anything else. I doubt Google would allow anybody to publish the source for Honeycomb itself before they publish it..

Just got my dock today and all I have to say is, wow. This is one helluva sweet device now. The functionality of both touch screen and keyboard rock!
I love the extra expansion, it's crazy how how much extra you get with the dock. I can now have the 16g onboard + 16gig micro sd plugged into tablet and 16g Sd plugged into dock. That's one helluva lot of storage for a tablet and for the price, it's outstanding. Add the two USB connections and it rules. Looks damn good too.
Great job Asus. Love my xformer
Ya it'd own even more if they fix the 4% per hour battery drain on the dock when the tablet is docked and it's sleeping.

Man, it never ceases to amaze me how many people just want to whinge on this forum. Just plain amazing - now go back to the dock-battery thread.
Love my dock too - use the tab about 6 hours a day, charge the tablet every or every second day, but it is fantastic when out and about. Last Sunday was out and about without access to Internet or computers for 12 hours - but my trusty TF brought me season 3 of "The Big Band Theory" to keep me entertained!
Maybe yours is an early version or defective, mine doesn't drain like that. I've had no charging issues. The keyboard will always charge the Transformer unless it is fully charged and use the keyboard battery first, if the Transformer is using WiFi or GPS it will drain the keyboard.
absolutely agree with OP. Fantastic device, even if it does have a few quirks. I wish the root development scene was moving a little further, cause there is alot of potential for this thing!

I'm starting to wish I were an affiliate, I've sold three people on them and they're all very pleased.
Me and my eee pad plus dock have now, reached an understanding, it is a truly amazing device when coupled with the dock, as an avid fan of android from launch and the owner of an original I pad, I have now realised that all my gripes are based on comparison with the I pad. OK it does have a few little annoyances, but on the whole after a month of use, this thing seems to be getting better by the day. I think Asus are bang on the money with the TF. The screen is superb and build quality better than most high end laptops. I agree with earlier comments about the negatives played against the TF being over the top, I myself was of the original wingers. But everything it does that works OK, it does brilliantly, and im sure the rest will follow.

So do you think it is hardware related? Would be a bummer, I still hope this is fixable with a firmware upgrade for the dock
Ordered my dock yesterday, will hopefully get it tomorrow.
Really looking forward to it after reading this thread
Yes, dock is really great.
I charge my TF once a day (during the night) and could work a whole day of meetings, mail replying and browsing without to be worried of battery lack.
However, I think the battery time could be better (perhaps, Prime 1.5 combined with 1.5 Ghz kernel is the cause), seems to be better when I was with stock system. The Dock also provide a very convenient way to type texts, etc... without transporting my portable PC.
A very good investment (even somes think it's not really necessary) on my side.

I was pretty sure everybody has this battery drain issue but now seeing some peeps come out of the woodwork just today claiming they don't. Now I didn't notice this battery drain issue until other users started mentioning it so then I paid closer attention to it, well that plus somebody put out a battery widget that showed you the dock level whereas before I didn't have a way to check. I have not shut my Transformer off while docked and let it sit to see if it then doesn't drain, if it doesn't then I suspect it's possible some of us including myself have some app running (maybe the dual battery widget?) that's causing it. I shall try this tonight.
I think the reason that a few don't see the draining is that they using the combo with a transformers at 100%. Because i doing it right now and i don't see the problem. So everybody with the problem should charge both to 100% and testing it.

No as I stated my tablet is always at 100% and I have this issue, I actually just leave mine docked all the time and when I put it up for example when I leave for work, or go to bed, my tablet is 100% and the dock may be anywhere from 30% to 96% and this issue happens, so it has nothing to do with not having it at 100% when you dock it.
I wonder, does everybody here use a dual battery widget? I've always wondered if maybe the widget itself is the cause, liek it' spinging the dock for battery level all the time. Would be interesting to see if we say charge everything up to 100%, uninstall the battery widget and reboot just to ensure it's gone and not left running, then let it sit idle and reinstall it later and recheck. I may do this tonight/tomorrow and see.
I agree. I ordered the dock with mine when I got it and haven't looked back. I use it with the dock probably 90% of the time. Its a good mix of function and form for my use. This device pretty much replaced a laptop/netbook/tablet for me. Combined with a WiFi hotspot from my Inspire 4G this thing rocks.
Cool
Just got the evo3d and wish there was something like this for it,
I'm loving the battery life on this. Maybe it's because the phones i've had was the G1 and G2x but still... And the charging is ridiculously fast. I all other other "tabs" should be jealous

The reason I'm here at the Thrive forum is the because of the battery.
It's replaceable, unlike the G tablet I have now.
I've had it since October of last year, and now the battery won't Charge past 50 percent.
Although I'm perfectly capable of replacing the battery myself (I've had it apart to reset it), Viewsonic won't sell me one.
What's worse is the fact that Modding the Rom voids the warranty.
Even if I go through the hasstle of flashing back to stock, any personal information is available when sent in for repair.
A replaceable battery is a requirement for my next tablet, and the Thrive is the only one I'm aware of.

Prevent Kapersky From Running
I suspect you are losing battery life because Kapersky antivirus is running on your tablet. Turned mine off and now I run for about two days with moderate use before I have to charge it.
Try changing Kapersky settings to NOT auto run upon reboot and see how your battery life changes.
Good luck!
Mine came with Norton, deleted that sh*t straight away. I generally just play music, download ALOT of stuff and browse the net, I'm managing 2-3 days. I'm not particularly sure on the exact hours but I use it very often each day. I haven't done anything like cycling either.
On another note this thing chargers so god damn fast. <3

Hookmeup From The Thrive
My wife uses ipad2 and i am using xoom. Noticed some glaring performance issues for the battery and the screen:-
1. The battery on the ipad2 can last twice as long as the xoom. I can get 3 days use of battery from the ipad2 compared to the xoom for about the same usage. When i use the xoom for about 5hours - mainly to do basic web serving, read books, with 3G turned on (rest of wireless turned off), i have about 40% battery left after 24hours. That does not seem normal to me, battery reports that the battery juice is used by the screen mostly (80%)...but my screen brightness is less than 30% level.
2. The you tube HD video clarity on the ipad2 is definitely more superior in color richness , clarity and sharpness. Turning up the screen brightness to 100% and activating the higher video quality in the xoom helps a bit but the improvement just makes a dent. I have read that the ipad screen is better...but what i see is a clearly superior ipad screen performance.
I almost hate to say this....ipad2 is a winner as far as the battery and screen quality is concerned. Or my xoom is a dud and i should bring it back to motorola?
thanks
Lawrence
P/s - Saw this article on the xoom screen performance from gizmodo.com.au/2011/07/best-tablet-display-ipad-2-just-got-dethroned. Looks like i am better of reading books with xoom and watch videos on the ipad2.
Honestly the xoom's screen is good enough for watching videos. But to say your not going to use it for video's because of a small difference in the screen.(I've compared them side by side) Why not read books on the ipad?
My xoom lasts me 4 days on battery browsing and playing games for 4 hours a day. But I'm using wifi only.

I got the xoom for the reasons you have highlighted and am thankful to the XDA community for the support and the hacks. It makes the experience so much more fulfilling .
Ipad2 plays the youtube by default in HD mode while in the Xoom, you have to select this play mode. Having realized this solved the problem that was borne out of my ignorance.
I hope the Tiamat 2.1 improves the Xoom battery life, i am charging it almost daily now since it drops to below 40% after a day of use.

I think he's trying to be sarcastic, lol.
If you're doing anything other than listening to music, the Xoom will give +/- ten hours of battery life. That's pretty good. I charge at night on my speaker dock and use it as my alarm clock. It's ready to go in the morning and lasts through the day with battery to spare.
Use SetCPU or CPU Master to set battery saving profiles if rooted with custom kernel/rom.

So you get 16 hours of battery life out of your xoom? Honestly, sell it back to Motorola for half a million or so, so they can find out how you doubled the normal battery life.
Sorry, I really like my xoom and am a Android "Fanboy", but we should at least try to be realistic.
I don't get what all the fuzz is about anyway. The Ipad2 has a better battery life, which is even written down in the specs. And that the xoom's screen is **** (relatively, considering the price class) has been mentioned right from the start. So, nothing new to see here
Tiamat 2.1 ROCKS
Hi,
Using Tiamat 2.1 with
1. Used Set CPU to increase to 1.5Ghz (settings = ondemand). Performance increase very noticeable and quadrant score has increased from 1800 to 3500!
2. Battery life has also improved, half a day use drops about 20% but will take me a few days to test this out for a fact. I suppose this because Tiamat has cleaned out the bloat ware Thanks ROM Team Tiamat! Also used Auto Memory Killer (got this advice from Xoom Heaven thread, Thanks diablo2224!). And all this with 1.5Ghz CPU setting!
I support android, use SGS2, SGS1 (wife using this) and Xoom. XDA is a great place where the majority of the views are objective and useful for the reader, to make informed decisions.

Lol seriously such a hassle to plug it in over night! Mine runs a couple days with heavy use thanks to rooting it and running setcpu...doing this to solve Androids battery guzzling from the factory issue I have a tab that can outlast the iPad, but more importantly excels in several other categories. When the source code comes out things will only get far better...this is a device for real techies...you want a pretty screen and the internet without ever getting the true potential with your device...buy a fadPad
Oh and stock I never had a problem with a full day battery life on this thing which is really all you need, but if you put in the twenty minutes of extra work you could have way better battery life...as far as the screen crispness it is subjective...some folks swear the iPad is better some say xoom has better quality but darker screen...the difference is minimal in my opinion and using better third party players helps...rant over
I'll be the 1st to admit that the iPad2 has a better display than the Xoom, but hell so do most of the other recent android tablets out there. I bought iPad2's for my daughters and I could never move to the darkside. I rely too much on google's free tools, being on the road so much I literally could not live without google maps and it's free voice navigation.
Make no mistake, I'm just as disappointed in the Xoom's display as anyone else and the still absent LTE upgrade (I know it's finally coming) have turned me off from Motorola hardware completely. Since VZW essentially gave me a 4G hotspot and allow me to use my Xoom as a wifi only device, I can't really complain anymore. I won't be leaving Android anytime soon, especially for iOS

So glad to hear it!
I own a Transformer Wi-Fi 16GB model. I have owned this since August when i got it for my birthday. I am a Huge android fan boy, recently at work for a thank you gesture, our small dev team received 4 ipad2s as a thank you from management.
I gave the iPad to my fiancée who is pretty much all Apple, (iPhone, mac pro personal and mac pro laptop work and now ipad2)
Last night i just charged both devices to 100%.
On Transformer (no dock) I turned unit off and turned back on and started NO applications.
on ipad2 i did nothing, just charged and removed it from charger first.
Removed Transformer from charger afterwards.
Went to bed at midnight.
woke up at 8am
IPad2 was still at 100%
Transformer - 95%
iPad2 is on latest iOS 5.01
Transformer - is on latest 8.6.5.19 and CPUSpy showed 8 hours of Deep Sleep
So the Transformer is performing as it should battery wise it just pales in comparison to the ipad2 and the battery management shows.
I can use the iPad2 very moderately throughout the week and never have to charge it.
the Transformer i have to charge every few days with the same moderate usage.
just such a bummer, everyone around me is jumping ship to Apple iPhones and iPads
here i am loyal to Android since the G1 when it launched, Mytouch, and my now Samsung Vibrant and Transformer Tablet.
I feel sometimes I am on the losing team. I am and WILL hold out for Ice cream sandwich but if ICS doesn’t perform like it should, I fear I may have to jump ship too.
there is only one thing i hate the most about Android.... the Lag/stutter in apps and home screen swipes.
iOS never does this at all yet every iteration of Android always has some type of frame rate/lag in the system.
yes i know people say Root and get on another rom but why should I have to? ios people don’t have to do that, their OS just works with no lag so why cant Android get rid of their stutter?
ok rant over.
You said you opened it and started no apps. But most apps auto start up on boot. Are you using a task killer?

Not sure a difference of 5% qualifies as "pales" Also Transformer is running multiple apps in background from last use. ipad most likely not running any if not started during this session.
And what is the size of each battery? Did you take that into account?
Sent from my Gewgle fone using XDA App
no i dont use a task killer, i used to on gingerbread andd froyo roms on my phone but after hearing everyone come down with the fire from hell like rain if they found out you were using a task killer on Honeycomb (because honeycomb is supposed to be great at App Management) i dont use a task killer.
the only apps i have on my transformer are the default apps and words with Friends.
also verified while charger was still plugged in and after tf101 was rebooted, that the recent apps or current runnin apps icon showed no apps running (im sure there were some other core android apps running in memory on boot up)
Also iPad2 was rebooted as well. i work in QA at my software company so i pay attention to detail and steps and made sure that both devices were as close to a specific state as possible for this test. in a nice world i would have taken an average with different app scenarios but i didnt feel like it for this personal test.
i the Device is in Deep Sleep then power and app management should be superb and they are for Android but compared to iOS app and power management not so much.
i even loaded PULSE RSS feed aggregator on both devices and the experience is night and day.
nice fast and fluid on the iPad2
on the TF101 with the same feeds and pages, very slugish and laggy and takes more time to draw each individual image in the windows.

Pales when combined with my ipad2 usage over a week compared to my Transformer usage over a week.
i can go over a week with no charge with an iPad2
i cant go more than 2-3 days with out a charge with a TF101
so deep sleep drain with nothing running on a freshly charged device showign 5% drain over night is a positive indicator of where your battery usage is headed with this device.

Im sure this would make a difference throughout a week period (which might be why i need a charge quicker over a week period vs. the ipad)
however i would expect if a device is in deep sleep, that its power/app and battery management would be a little better on par thats all.
i am in no way trying to start a war which i can feel is about to come, not looking for people to come down on me.
I am a true Android devoted user, i just can see the differences between the OS's with small things.
overall the Android experience satisfied so much more than the ipad does which is why i did not keep it and let the fiancee have it but there are some things to be desired from the iPad2 thats all.
Are you honestly *****ing about losing 5% battery over 8 hours? Really? Not to mention you were apparently running CPUSpy, so obviously the tablet wasn't completely idle as you have tried telling us 5000 times.
I sell iPad 2 devices and haven't seen this amazing comparison between the two devices in regards to battery life... My Transformer has lasted longer than the iPad many times so I don't know, every device is different I guess!

i dont care what your running, when you start up android, basically every app you have auto starts up. that is why when your phone starts up you cant just hop on and use it that second. get a task killer. if you want to do a test like this, please do it correctly before ranting to the community.
1. each device fully charged
2. kill all running tasks/apps on each device
3. either do the exact same thing on each device(with the same wifi/3g or whatever) or keep them idle and only check every hour
theese arent the best ways to test but there a whole lot more accurate then what you were doing
No one should be a fan of anything. If you think having better battery life is the most important part of your tablet experience, then get the ipad 2.
For me, the flexibility of android trumps the ipad's battery life. But that's just me.
This is capitalism. We shoudn't have a team mentality here. If you think the ipad suits your needs better, then get it. No drama here.
ok a few problems with that rant first as someone above said you were using cpu spy which uses resources and seccond turning on and off the tablet is the largest and quickest way to lose battery. when i reboot i expect to loose about 3% battery because of the power required so that 5% is perfectly reasonable

just such a bummer, everyone around me is jumping ship to Apple iPhones and iPads. I feel sometimes I am on the losing team. I am and WILL hold out for Ice cream sandwich but if ICS doesn’t perform like it should, I fear I may have to jump ship too.

Tell me about it, I'm still a BlackBerry fan! (For smartphone, not for tablet.) I've had that "losing team" feeling for a while. You get used to it. Use the product you love, not the one you think is most popular.

I've never tried that one. Used to use newsr, but lately been using Google's own Reader app for Android. Been very happy with it. Might be worth a shot if you haven't tried it. It's optimized for tablets too.

Well, you know, I read this, and I can't help but think, and sorry to be rude but... honestly, "who cares????". Are you away from electricity for more than 2-3 days at a time more than once a year? Maybe you like taking week-long camping trips to campsites with no electricity? Maybe? I don't know, but for most people I know, 2-3 days is tons. I just charge mine up overnight, so I never have any downtime due to charging. I'm struggling to see what the big deal is. I mean, yes, 2-3 days is less than a week, but does this really affect you?
Cheers!
I don't really think it's possible to match iOS in battery life...
1. It's real multi tasking on Android, apps consumes more power
2. Android itself is not as efficient as iOS (java vs Objective-C)
I would be skeptical of any device that after 8 hours (assuming you sleep eight hours) still reports 100% battery.

It's not impossible, my captivate does this with certain firmware.
3 points I want to bring up.
1 age of battery. It sounds like you have had the TF longer than the ipad. Which may say that the battery has not been calibrated correctly yet. Also older batteries lose their charge.
2 multitasking. Android actually leaves open apps and processes running. Ios will freeze or suspend them. Android's approach will use more battery.
3 your approach at testing such stats could use some improvement. For one, you could look at the processes running in stead of the apps or the open window list. That list is very innacurate at showing what is actually open.
Lastly imho how long either of these stay on is not really a point I would consider bickering about. For what the TF and ipad do the battery life is well past my expectations. Laptops and netbooks seem like a waste of money now for a good portion of the population in comparison to the computing power, portability and battery life of a tab.

Not until a tablet that I can type without lag, get a full office suite that handles more than one document and store a single file larger than 4GB, lol
These are just some basic stuff on PC.
I own an iPad 1 and a transformer. I use my iPad most days and my transformer about two or three times a week. The iPad still last longer. I don't see why everyone is so defensive about it, the iPad does last longer.
They OP said how he feels and that the didn't want to start a war. I don't understand why every thread is criticized by someone. End mini rant.
I have the OG iPad and the TF. The battery is better on the iPad. However the keyboard dock and additional charge time is nice. We can get into battery size and calibration and how OS runs background apps and battery drain. I'm just saying battery wise I agree with you, but compared to the Galaxy Tab and Dell Streak 7 I'm pretty pleased with the TF battery. I wish I could do that with my Motorola Atrix.
I'm ok with custom roms. They are fun and can help also with battery life.
Best of luck.

I completely with this. My experience with the ipad tells me the same thing. Battery does last longer with the ipad. That said, to me all the advantages of android outweighs (by a lot) the battery disadvantage.
Again, to the op. If you feel battery is the most important thing about a tablet, then I recommend you go with the ipad. I am not a fan of anything. I simply want what's best for everyone.
This was on the portal today. It's a Droid Incredible mod that apparently improves battery life dramatically. OP has a full guide in place with info on what each tweak does. Galaxy note devs, amazing as they are, may or may not be using these (or similar) tweaks for the Note. In any case, FYI

More snake oil... Improving your battery life tenfold with sysctl.conf changes when the radio dominates idle battery usage and screen dominates screen-on battery usage = bull****.
Maybe you can improve it a little - but tenfold? Bull****, and a ridiculously exaggerated claim like that makes me distrust any of the changes made.
I know what the prime power eaters on this device are, and sysctl tweaks aren't going to change those... Changing them requires major architectural rework of the kernel.

Considering the vat majority of my battery usage is screen drain I doubt very much this would do much for me.
I dare say the same could be said for all note users.

That's what I thought. You guys know the device inside out, so it makes sense to bring things like this to your attention.
Incidentally, the guy says he gets 50+ hours on a single charge. My Note gives me 48+ hours (with little wi-fi though, and at 1200 MHz), so it's not that we have bad battery life.
Overclocking, init.d changes, etc are all extremely irrelevant in terms of battery use.
The main battery hog for any modern phone in the past 2 years has and always will be the screen (of course unless if you're using something like the Xperia Mini).
I'm more than happy with the Note's battery life to be honest. It's certainly better than the Sensation and One X I had previously.
The only way we will see much of an improvement will be if they make a phone the size of the Note with a 3.5" visible screen. lol
Or a 10000 mA battery.

You must barely use yours at all.
I'm lucky to get 10 hours out of mine.

Dont care much about battery life if you are using smartphone with its big screen, alot of connection.
There are two solution, one is spare battery alway on pocket, other complete solution is change to cheap feature phone with 30 days battery life.

It's mostly phone calls, the occasional game, some music. Very little wi-fi though, and data only when I need it. Brightness set to auto except when outside (where it's set to max). The fact that I sleep atleast once in those 48 hours helps the battery life a lot

I finished completely charging my Galaxy Note at 02:00 BST. After I got up at 07:00 BST, the battery level was at 86%. I switched off the Wi-Fi, force stopped Skype and WhatsApp (these are the only 2 apps I have installed so far!) before plugging the device to charge.
Background data and Auto-sync in Accounts and sync was turned off ages ago.
Before posting this message, I switched on the Wi-Fi to chat with my cousin via WhatsApp for 20 minutes. Now the Wi-Fi and WhatsApp are inactive. At the moment of typing this message, my battery level is 42%.
I have tried force stopping some of the pre-installed apps such as AccuWeather, ApMobile etc but the effort has been futile. I am aware that I need to root my device in order to get rid of the bloatwares. I am having another issue with the Auto brightness feature which I have described in another thread. I have not ventured into the realm of rooting until now because I may decide to send my device to Samsung's service centre.
I cannot figure out for myself whether my battery or my device itself has a flaw or whether it is normal and there is nothing wrong.
I will eventually pose my queries pertaining to rooting and relevant subjects. I am a novice in the field of mobile computing and I am here to learn from you all.
Thank you all for your continued patience.
Your device has a flaw, that flaw is called Skype.
Skype is a notorious battery drainer.

Thank you for your prompt response Entropy512.
After I finish using Skype and subsequently signing out, I force stop it from Settings > Applications > Manage applications, either from Downloaded or All.
I use Skype on my phone to communicate with my sister when I am away from my computer at home, especially when I am at university. Thus, I am compelled to use it.
Do you reckon force stop is turning out futile? Should I get a third party "task manager" because the default/pre-installed Task manager seems incompetent.
Please do keep your expert opinions, suggestions and advise coming.

Install BetterBatteryStats (free if download from xda). Check for wakelock to see what app is keeping your device awake.
Just as a note, there is a bug in the OS for our Note if you use the USB OTG cable. Once plugged in with any USB storage device, the unmounter process would cause the device to unable to sleep, thus causing battery drain. The only way out is to reboot.

usb storage unmounter
soory is this usb storage unmounter wakelock bug in all the galaxy note device?
is there a solution
or is there any app that can terminate and close the wakelocks?
i know battery stat but i want an app to kill the wakelocks and system process
