I am still w bit confused wheather 2 units I had was faulty or not. ASUS definitely has bad QC. I was under the impression with constant browsing with low screen brightness and balance mode, we can only get 5-6 hours of battery. But some review sites state more and I even so similar discussion back when original transformer was released. So I want to verify.
Does anyone get over 8 hours of battery in balance mode, low screen brightness while constantly browsing? The easiest way to test is browse for an hour and see how much battery loss. If 20%, you get only 5 like I did.
last time i checked, i had 7.5 hours of screen on and wifi was actually my biggest battery hog by a 2:1 ratio, and still had 30 something % left. i dont have battery issues, i'm not sure if my transformer is a very recent build but i dont have ANY of the issues reported on this forum. no clicking, bleeping, battery problems or any other. my only problem is really just software related just like a lot of other have, lag, reboots, force close, but i know asus will fix that shortly

Did you have a dock? That's impressive number even if you didn't use browser at all. Still far superior to way I had. Do you mind browse formalize 30min and see how much battery drop you see? Also ,let me know which mode and brightness you used.

no of course no dock on...if i have a dock on i can last days. The most i lasted with a dock and moderate use like reading about 1-1.5 hours of zinio magazines, checking a few youtube videos, some fbooking, twitter, tapatalk and some browsing all that per day was at least 7 days...i'm not sure how much time exactly because when i use the dock the battery stats seem to reset every time i close the lid or at random times....
Look at these stats. My usage was: downloaded 2 issues of my subscriptions on zinio, downloaded tonights breaking bad episode off torrents, saw a few youtube videos (about two 5-7 min vids), facebooked a good half hour, read half my issue of XXL magazine while sitting on the crapper and while waiting for my ribs to cook for a total of about 45 minutes of reading, + making about 6-7 benchmarks test on antututu to play around with set cpu (all but 2 tests were on performance modem the rest were on balanced), and your requested 30 mins of non stop browsing which consisted of looking for a wallpaper and browsing on ebay, all that in 3:26 hours and i got 26% battery drain, brightness was at about 30%, and this is what i consider it to be HEAVY use as screen on time is 1:56h.
Usage before your 30 mins of browsing
after your 30 mins of non-stop browsing:
So about 8% drop in 30 minutes of browsing and this is including 24 wallapers i downloaded from google images.
P.S. I'm rooted, not unlocked and i'm not debloated as i,m waiting for JB to really start playing around with the pad
mine would drop about 10% every 30 minutes watching videos - netflix or local.
my note, however, droped 25% after 3.75 hours of straight usage. this was with 3 episodes of The Unit, drawing, web surfing, and streaming netflix. i had to do all this while my daughter played around at monkey joe's.
all the reviews i've seen show the that the infinity gets 8hrs at 50% brightness. all my usage on both infinities and the gnote were all under 20% with headphones.
With dock, I am able to get 10 hours of straight use (non stop) playing various games. Played Angry Birds, Dead Trigger, ShadowGun, Amazing Alex, Drisk, etc. No wifi was on. I get about 6.5 hours on tablet alone.

It's a joke. All the ignorant ipeople always say android gets horrible battery life on the tech forums I go to. I find it funny that my tablet actually does get bad battery life. Then again, I never use powersaver mode so I guess its fine.
le rustle face
Thanks all for taking time to post a reply.
So I guess what I experienced with 2 units were indeed what it is. For some, perhaps many, infinity's battery life may be enough but unfortunately for my use it was just too short. Video play time or ebook reading time were totally fine. Its when we use browser, the jump to 20%/hr drain i.e. mere 5 hours of battery life with tablet alone. This won't last me a whole day. Sure dock would give extra power, but I got Macbook Air so if I want to carry actual laptop, I would actually do so. One reason I have been purchasing different tablet is mainly the use as tablet.
I don't know if it is fixable by firmware, but Samsung certainly does seem to achieve pretty similar battery life whether using browser or not, so I wonder it is something at the software level that ASUS is missing.
But I really appreciate all for answering this question.
Thanks
I too spent a considerable amount of time researching this as I thought my unit may have been defective. Long answer short it gets about 5 hours if you're web browsing even with low brightness.
I'm hoping a software patch can improve it at least somewhat, as having the WIFI on seems to drain the battery excessively compared with it off.

Yeah definitely that's what threw me off. We all talk about/assume higher pixel density thus more battery drain, which made sense but infinity's battery life with book reading weren't bad at all. It's the WIFI, which is very strange.
Hi
The Wi-Fi usage seems very high on these. No way should the Wi-Fi be using more power than the screen, certainly doesn't on my HTC One X, which due to laws and regulation will be transmitting with the same power as the TF700, but the screen will be using a lot less power than the TF700 as it's smaller so needs less back-light, so if anything Wi-Fi would be an even bigger percentage on my phone compared to the TF700, but rarely is Wi-Fi a quarter of the screen use, often much less.
Unless that Wi-Fi is doubling up as a small microwave oven, power usage should be quite a small percentage, so either the TF700 is mis-reporting Wi-Fi usage, or their is a fault (software/hardware?) with the Wi-Fi card.
Regards
Phil
no , we can not
I think we can not , it is too fake to say the battery would last up to 9.5 hrs.....
The wifi indeed has some problems, which would comsume more than half of the battery life.
Maybe.... asus intends to increase the wifi power to improve the performance!

Well many on this forum says its miscalculating, which may partly true but not entirely because as Battery drain was my concern on this system I did multiple trial and basically WIFI on with active browsing crank up the drainage to 20%/hr from 10%/hr without browser i.e. WIFI on but just reading ebook. So WIFI is truly consuming battery.
On my Galaxy Note 10.1, whether actively browsing or not the battery drain still remains 8-9%/hr. So yes. WIFI may consume more power but should not be twice... unless WIFI unit ASUS using is some weird one.
The storage brand and Wifi units are usually something most companies don't put on their specifications so hard to tell whether ASUS tried to use really cheap ones there to keep the paper specs great, yet functionally not meeting up the expectations. Or ASUS may simply have yet to catch up software people. Whether truth or not I heard Samsung hired quite few programmers relatively recently. And compared to my old Galaxy Tab 10.1, I definitely see marked stability/smoothness improvement on the Galaxy note 10.1 which also uses ICS just like transformer infinity.
The most interesting comparison for infinity would probably be though Xperia S tablet. Because that one also uses 1GB RAM, and Tegra 3 (inferior to one in infinity) and runs ICS. So if ICS there is as stable as Galaxy Note, at least we know its not memory, its not tegra architecture. Though storage will still remain as potential source.
But going back to the subject, battery life on infinity on the contrary to some here stayting dock providing extra battery, I find not great. Even with docking station, it either barely matches up with that of Galaxy Note 10.1 tablet alone or perhaps less especially if you play games.

I think in the TF700 they are using a Broadcom SoC for Wi-Fi, what ever it is though, drivers will be provided and it isn't much different to plugging in a Wi-Fi stick to a USB port. Perhaps they have configured it wrongly or there is a hardware error or software reporting error with the Wi-Fi. I can understand why people say it is a software reporting error as most people acknowledge it should never be that high as a percentage of power use so don't believe the figures. If they are the correct figures for Wi-Fi usage then something is very wrong somewhere.
Regards
Phil
I've been having the same problem. Wifi really does seem to drain my tablet too. I usually turn it off as I use juice defender and it helps immensely but it is kind of ridiculous for wifi to eat so much, especially when I want to start using the internet.

How long have you been able to extend the life of your battery per charge? What type of settings do you have your tablet setup as? What apps do you rely on for system stats. I play a lot of heavy graphic games like Modern Combat 3 other Gameloft/Tegra3 games. Titles that shows off the power of our tablets. I also love to stream movies/shows and YouTube.
So far the shortest life span has been about 4 hours on heavy gaming/light browsing/and light streaming for my use.
How long has yours been lasting you? (I would love to see pics from battery stats)
Here is mine this is the longest so far...

Edit: Forgot to mention that I discharged it to %0 until tablets shutdown on its own. I then charged to %100 and used Battery Calibration app (Root required) to calibrate my battery. Now getting 12hrs and more with the settings mentioned above.
Update: some of you including myself initially saw that the speeds would hang on 1500MHz or 1600MHz in my case. Which would drain our devices rather quickly. If your rooted, the way I fixed the issue of it hanging at 1600MHz was use Setcpu. Set it for Ondemand. Adjust it to Max:760MHz Min:102. It worked!! It stayed within those setting. You can now set it to your specs. Sometimes the system overrides your settings to accomplish a task that you are doing, but still much improved.

Good question
The tab I have usually last about 7.5 hours.
Balanced power
WIFI always on
Bluetooth off
GPS on
10-12 apps in the background
Brightness a little below a third
Last night the battery dropped to 37% in just about 4 hours then it took 2 hours to drop below 30%.
I dunno why.
It is difficult for me to get an accurate reading as I put in on the dock on and off all day. With the dock I get a full day of constant use. I don't mind charging it every night. As long as it gets me through the day I am happy.
I'm hoping this won't get moved to Q&A so we'll get more responses.
I'm getting about 5 hours of screen on time at balanced with brightness 1/3 of the way up. Mostly browsing the internet with wifi on the whole time, Bluetooth off, GPS on. This is from 100% charge to 0%. Seems low, tried a cold reboot it didn't improve. Maybe improving slowly over time. Currently showing exactly 50% with 2 hours 42 minutes screen on time.

So ever since I discharged it, until it shuts itself down. Charged it from %0 to %100 then used Battery Calibration app (Root needed) to reset battery stats. Now it seems to be lasting longer. Used to get on average 4 hours before that now 12 hours plus.

Erratic battery life
In balanced mode, I have GPS and Bluetooth off, brightness at about 40% (auto brightness is off), wifi off about half the time, keep apps running to a minimum and tend to use the TF700 in the same manner every day. Battery life still varies significantly and 6-6.5 hours is typical although I did get about eight hours one time. Wide swings in battery life are common. If I do play a game, it's usually a simple arcade game and rarely for more than 30 minutes. The rest of the time is spent reading or on the web. A Kindle Fire lasted longer doing the very same things with the wifi on all the time.and screen brightness at a higher level.
Screen flicker in balanced and power savings mode is pronounced from the auto-dim/contrast feature and not something I would expect from a tablet at this price. If it's supposed to save power, it isn't working.
The drop in battery power isn't consistent and while wifi is always at the top of the list followed by the display, I've seen battery readings slowly and steadily decrease and then suddenly plummet without warning. At this point, if the battery reading is 20-30%, I can't take the TF700 anywhere without charging it first because the remaining battery power won't last very long. Battery power seems to drop like a rock at 25% and below.
The tablet is pretty close to ideal except for the battery and, given a choice, I would prefer a thicker and heavier tablet with a more powerful battery over a thin tablet. I'd be ok with eight hours of reliable battery life with wifi but it has to be available in one long session and without screen flickering. A tablet where eight hours of battery life is intermittently spread across three days doesn't work for me.

The reason for the low battery is this; Asus did not put a larger battery in Infinity compared to Prime.
Both devices have the exact same battery, but since Infinity runs at a higher clock speed and has a higher resolution screen, it drains the battery much much faster.
You can't really fix this with software. You can however lower the voltage with a custom kernel, making slightly improvement....but that'll also make the device unstable.

Definitely the higher resolution screen plays a major role. Along with a faster Tegra 3 Processor.

I thought Jelly Bean was supposed to help extend the battery life.... "slightly".... by running processes differently...
I know it should increase graphics benchmarks a little...
Did I translate my readings incorrectly?
if i use it without the keyboard dock, i would get more battery life than my mac book air. but if i watch hd YouTube video or movies on it i will have more than twice the battery life then the macbook air

My battery life feels like it's too little, I've been wondering if I have a bad battery. I get about 4 hours of use but even with that, the battery only lasts a day, discharging 8 to10 % per hour while asleep. This is with minimal usage, mostly email, web and some photo work. It's like my smartphone which sits on the charger every night, except I never charge the TF700 overnight.
If I use the dock I get easy a full day with more than normal use. Fact is I don't think I could be using it more than 4 or 5 hours a day, just seems physically impossible. I've shut down all sync and wifi functions, no gps and nothing running in the background.
I'm gonna try the full discharge and 100% charge to see if that helps. My subjective opinion is that I'm getting about half the battery life as my TF101.

When I first used Cool Tool I realized that for some reason I was constantly hitting 1600MHz under just normal browsing and viewing XDA!! Like it kept getting stuck. Which would explain why my battery only lasted 4 hours. After adjusting using Setcpu and Ezoverclock it's top off at 1400MHz Min of 102MHz and I've gotten better results and it no longer lingers at 1600 MHz

FWIW while my battery doesn't last long with the screen on, it doesn't drain much while asleep. I'm at all default settings, wifi always on, and I just picked up my Infinity 11 hours off the charger at 96% battery.

Hiya JJ* .......... great post !
IMHO.... this question of 'battery life' is more like 'how long is a string?' question .....< sorry for this pun>
I am glad JJ* mentioned that the BATTERY NEEDS TO ME FULLY DISCHARGED ....
This is ONE VERY IMPORTANT and a KEY STEP.....
few yrs ago; when i had a working life <lol now am retired dude and lovin it> ...i happen to get assigned to do lots of work on "BATTERY LIFE" for CMOS & NORMAL POWER use in laptops (sorry cannt do mfgr;s names etc) ...........
I found that ( discharge is THE MOST CIRITICAL STEP ) is keepin that battery - life and reduce 'discharge rate'.....< providing all other usage factors were kept even/equal>
Another tip I found usefull -
Uninstall / Shut down any "APPS" that you dont use often - or hardly use
SHUT DOWN non -needed running apps >>hit TaskManager often and shut off RUNNING APPS ( i even shut down things like GSTORE etc etc ) .. and often amased how much differance it makes ..
so I will be posting my status and pictures soon ... to help towards some 'benchmarks' soon...
on average - I dont need charging untill OVERNIGHT - and mine is used 12-16hrs a day ( with dock though )
There is a 'sticky topic' on BATTERY saving tips ... on this forum

Are you rooted? If so use setcpu and change the max to something smaller then 1500MHz try 1300MHz and see if it changes. You may just need to get it unstuck. Same thing happened to me and after changing the value it now cycles normally from min/max
As far as your Dock. I'm not quite sure what you're saying. What is it doing when you connect the dock? Are you able to type with it? Is your settings for the dock correct?
In order for the dock to function correctly the default keyboard should be the Asus Keyboard under Settings/Language & input/Keyboard and input method/Default/Asus Keyboard
Brought to you by my Asus TF700T
Speaking of the dock, I really think the TF101 did a better job utilizing the extra battery. On the TF101 the dock battery charged the tablet battery as long as they were connected. This meant I could use the dock like a cover and when I get to where I'm going the tablet is at 100%. I use it down to 80 or 90% and when I get to my next stop it's at 100% again. The TF101 dock never discharges farther than 3% but it keeps the tablet at 100% all the time it can.
My TF700 with dock lets the tab get down to around 76% before it even starts charging. If I take it out after driving for an hour it will still be discharged the same as if it wasn't connected. In addition to this behaviour it also seems like the dock discharges itself rather rapidly. At times I watch the tablet and the dock both discharge at the same time. This never happened with the TF101.
I should add: I'm using a stock TF201 dock (99$ BB score). Don't know if the ones badged TF700 work any different.

Mine isn't on 1500 always but its there a lot while browsing. Basically anytime chrome is doing anything, even now typing this. When its just idly displaying a page that's already rendered it'll drop down to 475 then 102 until I scroll. Is this normal?

Yes its normal. It does its best to optimize it's cores for the smoothest experience. Although with the Infinity and ICS it gets confused at times since its not optimized like it should. Jelly bean project butter is suppose to eliminate and optimize our power house tablet like its doing with the Nexus 7 running JB. Cant wait for it to drop!

On my tf300 the screen used about 90% of the battery, while my tf700 says wifi uses about 55% and screen is only about 40% Is this normal?
Could people post some screenshots of their properly functioning battery usage? Maybe this will help us figure out if our batteries are acting normally.
Its so frustrating... after going through 6 devices exchanged... i think i got a good one but my previous experience has me scrutinizing this one while i worry about the 2 remaining days on my store return policy.
Normal
You've got a normal unit in terms of battery life. This is my third unit and I too had concern with battery life in the past so ended up taking some poll on this forum. Also I compared my original and second unit with battery life and they were identical.
So anyways, my conclusion which seems to be agreed (or at least noone said different) is followings:
1. You have about 10+%/hr drain if reading ebook or watching video in low brightness setting (even wifi on).
2. Active browsing drains battery significantly and goes up to 20%/hr hence only 5 hours or so of battery.
3. Power save mode can get us additional 1+ hours.
ASUS advertized 9.5 hours are in power save mode, video watching (with WIFI on but not active browsing).
*These are screen on time.
Some of us are hoping, this doubling of battery use with active browsing is fixed by software in the future but most likely hardware related so chance is slim here. But I now got docking station, which I use more like portable charger than the actual keyboard, and with it I am fine with battery life on infinity.

Wi-Fi is way to high, my Nexus 7 has been on all day with Wi-Fi enabled, I've only used it for a few minutes so far today with the screen on and Wi-Fi is 8.6% and the screen 48%, the same ratio is seen with my mobile phone HTC One X.
With a tablet with a 10" screen, that is by the far the biggest consumer of power even if only used for a handful of minutes, nothing should be above the screen in terms of power usage. I've pointed this out before here with other similar screen shots of power usage, there is definitely a problem there.
This is either a hardware issue affecting many TF700's, or a software issue. It might be worth checking that the Wi-Fi isn't set to high performance mode as that will prevent it entering low power mode and can increase power consumption considerably.

There is no faulty hardware, its just bad hardware design. This tablet has a high res screen but a tiny battery. The same exact battery that the Prime had.
Battery life cannot be improved, gotta live with it.
Docking isnt a real charger because dont charge tablet batterty. That is good because dont spend power on convertors up/down or down/up is more like a second battery.
I used to buy a 3200mAh Extender Battery for my note except the heat who means losing energy inside was only a 2800mAh battery at 3.6V and from this get up to 5V to charge via usb the SGN and from usb 5V phone go down till 4.2V another 0.8V or close lost on heat.
So docking works ok as second battery w/o pull up the internal one what is ok for some and not ok for others

My wifi is using too much? Can anyone confirm this please? Ive been begging people for screenshots of their battery screen for days and nobody will help me
My store warrenty is almost up and then ill have to deal with asus which seems to just send the unit back without repairing anything
Please someone ffs. Ive ****ing had these for almost 2 months with out being able to even start to enjoy it. Ive went through 6 faulty units and i just dont have any faith in this device anymore. Honestly the last time i buy an asus mobile product thats for sure. Im not rich and cant afford to be spending 500$ on broken alpha-test level equipment. This is the tablet ill be using for the next three years and i just want to know if its broken
Maybe ill just return it anyways and experiment with them that way, but i think thats a rather dickish thing to do and would prefer to avoid it, especilly after going through 6 legitimately broken units in a row

Wi-Fi using more than the screen isn't normal on any other device!
My Nexus 7 is currently on 3d 6h 39m on battery, screen is 60%, Tablet idle 22%, Wi-Fi 5%, Media server 5%, FireFox 3%, Android System 3%
Screen on time is 2 hours 48 minutes, and Wi-Fi on time is 22 hours and 22 minutes, I have 53% battery life left, now that's normal

Yup. Again actual statistics to calculate they use is probably based on the hours it is on i.e. for wifi even during the sleep/screen off. So % is not really accurate though WIFI does drain battery.
Just go with 10%/hr (without browse) and 20%/hr (with browse) and see if your unit meet this.

You simply cannot rely on the stat that transformer infinity is showing. Because I can basically flip the stat by using straight 3 hours from 100% with screen on time in which case WIFI is on only for 3 hours as well as screen. Then % is signficantly different.
So yes. WIFI draining more than screen is abnormal; however, the method of calculation that ASUS is using is simply inaccurate.
However, I still do believe WIFI module that Infinity using is problematic in sense that suddenly with browsing the battery drain rate almost doubles, which is simply too much of battery drain but definitely not as much as the stat shows.

If you really dislike it so much, then return it and move on already! It sounds like you are very unhappy with the device. After trying 7 different TF700's and still not being happy, why are you even thinking of keeping the device? Regardless of what others believe and have experienced it's pretty simple - you don't like it and you obviously can't enjoy it, so why does it even matter what others think?? I just don't get it... Geez...
Please, return it and get something else already!

So as most of us already know that the WIFI when it is actively in use e.g. browsing, it drains a lot of power. Essentially, the battery consumption doubles when when actively browsing in comparison to the playing local video (~20%/hr to ~10%/hr). This does not happen on any other device I have used in the past.
Today, one forum user said interesting thing:
SmartAs$Phone said:
In fact the WiFi is so cranked up on these baby's (same as for Primes) that it uses as much or more battery than the screen, and it's a pretty hungry screen! I wondered why they kept the WiFi pushed so hard on the Infinity, was it that Asus wanted to show just how great it could be (and other than no 5 ghz. radio, it is really quite good - I get roughly 4 times the throughput I had with the Prime, and twice what the TF101 could deliver) or was it just leftover coding from the Prime?

Not sure if this is true, but make sense if the latter is true. I wonder if there is anyway to turn down the power supply to the WIFI unit because I like my infinity with ANR pretty much now gone, beautiful screen, not real IO issue (for practical use), my only complain is actually battery consumption of tablet alone when actively browsing. So if this can be fixed, it would be phenomenal news for me.
I personally don't know. But anytime you have radios on, there is going to be additional battery drain. Not saying Infinity's isn't excessive.
You could try using the Power Save mode.
Unless I have the screen on, when the WiFi is turned, I can go all day This is just checking email, IMs, little web, and so forth. I do have a C8 release.

It's definitely true the WIFI component should drain battery; however, I think in infinity it is excessive when compared to any other tablet. And you are absolutely right that just having it on does not drain much but when actively browsing it does. The easy way to notice this is, if you watch video (local) the tablet alone can last up to 9 hours i.e. 10-12% per hour battery drain; however, as soon as you start active browsing not even streaming but simply surfing web it becomes ~20% per hour drain.
Sometimes antenna like devices can increase its signal gain based on how much power you supply to it. So the other guys post made sense to me in theory at least.
Hello,
I'm new here and have a quest about my new tablet
I bought the Transformer Pad Infinit a few days ago and I think that I could use the battery for 9 hours more or less.
But my battery is extremely weak, I just use this 3 or 4 hours with the GPS off and bluetooth off too. The wi-fi is just on in the half of this time, and waht I do in this time is play some games and use the internet. I use the "Energy Economy" mode all this time and the light of the screen is in 20%.
I guess my battery is more weak than others... What can I do to "fix" it?
I would to say "thanks" for everyone, and I'm sorry by my english, I don't know english so well
The battery in your Infinity may be not charging to 100%.
I don't get 9 hours with moderate use...I see around 6 hours.
My wifi and GPS are always on and the screen is about 30%.
The batteries aren't supposed to have "memory" meaning: they should be able to be charged over and over from any discharge level back to a full charge.
There also might be something running in the background that is taking down your battery charge.
Have you browsed the battery saving tips in the stickies here in the TF700T forums?
Is your Infinity the LTE version by any chance?
Some info:

First: Thanks
I search in the internet and I found that the Li-Ion batteries have to charge arround 30%~50%. I do it much times.
I was using a animed wallpapers and I change it by a normal wallpapers. I guess this make some efecty
I search here in the forum too, things about the battery saving, I found somethings that can be helpful, but no "so beautiful"
I don't have the LTE version, I guess nobody have it, Asus is so stupid when we talk about "3G/4G"
I don't know why, but mysteriously, the tablet use about 600mb of RAM and also nothing is running, just the things of the systen.
I guess it's strange, maybe that interfere in the battery life no? But how can I "fix" it? SImply have notthing running and 600mb of RAM are in use.
Thanks again, and again: sorry by my english

That's OK. Unused RAM is wasted RAM, and unused RAM uses exactly the same amount of battery as used RAM, so no need to fix anything here. Interesting for battery use is CPU utilization by running processes.
I have to admit the battery life is not brilliant on this tablet. It very much depends on the usage, this wasn't really the case with previous LEAST powerful galaxy tab 8.9. Even during playing games it easily lasted 8-9 hours.
Worst infinity battery times observed ( balanced mode, brightens < 30% )
- playing hard core 3d games, like dead tigger, battery dead in 3-4 hours
- playing less intensive games, battery dead in 5-6 hours
- browsing battery dead in 7-8 hours.
- watching movies, battery dead in 8-9 hours.
so anything between 3-9 hours can be normal with infinity. I cannot even imaging battery life in performance mode, IPS+ full brightens
I was with fear, 'cause for a moment thought that my battery was the only one that is "not so beautiful" But I saw that is not a problem with my tablet and yes with this model.
I'm Brazilian, here the Asus is a perfect nothing. Here we have just the TF101 who comes with 1 year delayed. So I buy the tablet in other country and I don't have warrancy, if my battery was with some problem I don't know what I would.
Here if I call to Asus they would hit the phone in my face before I can say "Transformer"

Ummm...
So you ... own the Asus Infinity TF700T?...or the TF201?
...don't get hit in the face please!...especially with a phone...maybe a small phone wouldn't hurt a lot.
I hope your face doesn't get hit though...
God I love Google Translate... :laugh:
Asus very clearly says "Battery life tested under power saving mode, playing 720p video playback, Brightness:100nits, default volume with headphones." on their website. If you try something else, you'll get different results. Basic scientific fact.
Also, I can't stress this enough: Kill off all bloatware! No you don't need to root the tablet for it (most of it, anyway.) The more processes you run in the background, the more power they consume. Simple as that.
And WiFi EATS battery like you wouldn't believe. It's so horrible it's not even funny. The WiFi unit is very powerful, which is why it eats so much. So yes, using WiFi will eat your battery.
andoid uses RAM differently than Windows. Forget how it works there. Android reserves RAM for processes, even when they're not in use.
Could be the Google Location bug? there's info on that here somewhere too.
Go to settings --> Battery and see what uses the most percentage.
Like many others, I've scratched my head regarding why some seem to be able to get 7+ hours of screen on life while others get only around 3. I know the typical response is wakelocks but those SHOULDN'T affect screen on time much, when the CPU is already awake.
I have noticed that it seems that my device dies much faster when it gets hot, which makes sense, but I've never seen it affect a device to this extent. One time, I fully charged my battery and only got 3 hours SOT merely doing nonstop web browsing on WIFI without putting the device to sleep at all. Yesterday I even froze all apps except the stock ones after flashing PA gapps on Omnirom and my batter was worse than when I had 100+ apps and greenify. Usually I get 3-4 hours SOT a day of normal use on LTE with intermittent, cooler usage. When the device gets hot it also doesn't want to charge nearly as quickly either.
Therefore, I have a simple request: post your best or typical SOT and how often your device gets noticeably hot. I'd like to see if there's a trend between heat and SOT. Or at least vote in the poll. Both would be preferred.

lol, are you serious?
we see a large variance is battery life because we all use our devices completely differently. plus we all have different qualities of phone/data signals, we all use differing brightness for our screems(some auto some not), we all do differing things to set up our phones as we want.. do you want me to go on? and the temperatures, they vary throught the day, depending what you are doing, depending on the temperatures around you. sometimes they can get very hot, sometimes they stay cool with lighter use. i get 5.5-7h screen on time every day. my phone can see temperatures of 88C to 0C daily.

And disabling all apps to take the user setup out of the equation doesn't change things? Or the fact that I only got 3 hours SOT just web browsing? Sure, there's definitely variance involved but it seems like there's more with this device than I've ever seen before. Most devices I've used have been mostly consistent among users and don't have some people complaining about 2 hours versus 7 hours SOT in a short period.
It's easy to say it's environment variables or user error when you're getting 5+ hours every day but when you're someone who's been around the block with Android and phones in general and can't break the 4 hour mark ever, you start to wonder if there's more than initially meets the eye. I don't mean this to attack you, I'm just not sure what else yo do. I've tried undervolting, underclocking, keeping brightness down, greebifying (BBS looks fine), modified location settings, stayed on WiFi, turned off WiFi, removed apps, etc, and nothing helps SOT, only sleep drain.
The bottom line is, have you noticed your battery drains faster when it's hot or is it pretty constant? I'm just wondering if some devices, due to a lower PVS value or some other property of their chip, run hotter and drain more current doing the same tasks. Trying to eliminate the possibility.
P.S. Have you noticed the XDA app modifies or quotes the post above what you press? I have, as you can tell...

ive had g1, google ion, nexus one, nexus s, galaxy nexus, nexus 7, nexus 4, and the nexus 5 now. every one of them has/had great battery life. its the way i setup and use my devices. our use is a huge variable. every single person uses their device completely different. for example in setup and use, you use the crappy xda app, that uses a huge amount of battery, i use the browser, and never install those kinds of apps. many people have facebook installed, i uninstslled it more than 2.5 years ago, i use the browser for facebook. facebook is also a battery killer. i can go on and on. then theres the variances in phone and data signal. bad signals can get more battery drainage, terrible signals can be battery killers.
anyways, you said sleep drains. i bet you have a few badly behaving apps, or you are using the wrong kernel for your device. or, it could just be the way that you use your phone is the reason you don't see 4+ hours sot.

Fair enough. I know the XDA app is bad but didn't think it was so poorly coded that it's a battery hog. The site needs a mobile version IMO.
What do you mean by "you said sleep drains"? My device sleeps quite nicely, I just mentioned that because that's usually the battery life people complain about but that's not an issue here.
I'll try doing a full wipe and not just freeze all my apps and leave just the stock stuff for a couple of days and see if that makes a difference.
Yeah, I wish there was a way to quantify how much signal is killing your battery. Sure, there's the battery page in settings but more detail would be wonderful.
I've experimented with most every kernel but it never really made a difference. I mostly stick to Franco.
Either way, I'd still like to get some crowd data on what they see. Two devices with opposite results is hardly conclusive (even though all your devices have been good, that doesn't necessarily rule out the possibility that there's a bad batch of CPU's or batteries in some Nexus 5's, unlikely as that is.). Everything you've said is valid, but I want to entertain the notion that, while that may be the problem the vast majority of the time, there could be another cause. If I find a bad behaving app on my phone or I just have crappy signal, great, but more data is never a bad thing.

as you can see ill hit more than 4 hours sot, probably 5.5-6.5h sot. you notice my battery stats, heavy usage, but none of those silly apps eating battery, for me its mostly browser. yet earlier i was at 81C, because i was pushing my device. now cpu temps are around 44C.

That looks like it rules out CPU temperature then, if temperature caused heavy drain you should see a steep slope at that time. Did your battery ever get hot?

This is the first high-end smartphone I've owned that doesn't get hot at all. It'll get a little warm from time to time, but it's never anywhere near what I'd call "hot."
Samsung phones, on the other hand, get freaking HOT. My GS2 would get so hot at times that I could barely touch it, and my GS4 wasn't a whole lot better. My wife's GS3 will be blazing hot in its case when she's just been browsing the web or on Facebook. My N5 is never even close to as hot as Samsung phones have been in my experience.
Hmm, I dunno if I'd say it is painfully hot (thought when trying to wireless charge and use it it gets pretty bad) but certainly quite noticeable. What was the temp in degrees Celsius? I see 70s on the phone and 40s on the battery quite frequently.
Sent from my Nexus 5 using xda app-developers app
Phones that get hot to the touch are actually doing a good job dissipating the heat. Though it may become uncomfortable to be absorbing some of that heat it does have to go somewhere.
Nexus 5 uses aggressive thermal throttling to keep the phone fairly cool and according to Anand has a heat spreader between the SoC and battery unlike the Nexus 4 which caused the two to heat up quicker.
The only thing that will stop me from getting over 4hrs SoT (3.5 - 5 based off usage) is if an application decides to keep the phone awake endlessly. I've seen it happen for Google Search and a few others randomly at times. Reboot or force stop fixes that up.
My nexus 5 battery also seems really crap, and the back gets hot very quickly. Everything else on this device is 100% perfect. Ive tried everything i possibly could (Different kernel, undervolting, lower cpu freq, change governors, low brightness, most connectivity settings off, ok google off, and many more battery saving aspects) yet i still can only get around 2-3 Hours sot with light usage (XDA, web browsing, social media). Is my device somewhat faulty? Or is it supposed to be like this? And normally when i play games, it drains at a speed of a percent per 40-60 seconds.
And please dont go about bashing me, im just a bit curious on how people get around 6 hours sot.

I haven't really had to do this on this phone, but I used to chase Screen on battery drain issues with Cool Tool from the play store. It floats a highly configurable window on the screen that lets you monitor a lot of system parameters including current draw - which is probably what you are most interested in here. I think you can also monitor the temp of the device, the cpu utilization, etc., etc. This lets you play with different settings and what not and get more immediate feedback as to what is happening with your device. In the screenshot, I configured the floating window only to show current draw...should be the pink 182 mA.

Thanks for that link but am I right in assuming most of it's functionality won't work correctly in KitKat? That has been reported with most battery or CPU monitoring apps so far.
I've been looking for something to show me current draw on stock but have only had battery widgets show me the current battery voltage which I don't understand the significance of. Starts at 4300mV when 100% and drops to about 3900mV when nearing empty.
