I've been keeping mine on Airplane mode when i'm not using it, mainly because at work I dont have wifi so I need to tether anyways, which means I prefer to keep my Atrix plugged in. So, I just keep it on AP mode, in my backpack, and when I need it I just switch that off. I dislike how I can't seem my battery stats though

I think that live wallpaper is also eating away at the battery. i had the Aquarium on for about 2 hours and i saw the battery life draining faster so i changed it. No reason to put those fancy walls.

It's been about 5 hours since my TF was unplugged, its on airplane mode and still at 99%
[Eee Pad Transformer Q&A, Help & Troubleshooting] timtlm:
After a full charge, it dropped 6% in 12 hours of being idle, wifi on. Used it for 3 hours straight, and dropped another 22%.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Interesting. Makes me believe that the Sleep of Death and battery drain with wifi on stdby are related.

MY Nook color stock on stdby only drains about 1-2% overnight (7-8 hours)!

When on CM7 initially and with wifi on it would drain 2-3%/hour overnight on stdby.

People are saying that when TF is in airplane mode it is not having the sleep of death issue forcing a hard reboot.

MAybe the Devs can look at logcats etc. and see if something is causing a significant power drain with wifi on overnight that could also be causing a SOD.
[Eee Pad Transformer Q&A, Help & Troubleshooting] HideYoKids:
I unplugged my TF at 6:30am, it's been in airplane mode ever since with the exception of 2 minutes to download Baconreader, its at 97%.

3 percent over 9 hours is pretty good.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
My battery life sucks big time. With medium use I am getting about 5 1/2 hours...Brightness at the lowest point, just surfing and some music. No live wallpaper and bluetooth is turned off. Two widget on my homepage weather and email.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
I was wondering how low of a % could you go before having to recharge it? I read before that its not a good idea to go below 30%. Is this true? I am not having the best battery life so I am having to always charge each day......:(
[Eee Pad Transformer Q&A, Help & Troubleshooting] A Naked Emo:
For those of you with docks, is there any way to tell the charge remaining on the dock? It looks like the indicator is only for the tablet.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
WTF...around 3:30 am it had 65% decided to enable airplane mode turn it back 5 hours later its down to 15%........:mad:
[Eee Pad Transformer Q&A, Help & Troubleshooting] gadgetfann:
I don't think there's a way to tell the battery life left on the dock, but I can say that my battery life with the dock has been insane. I've been using the TF for the last 4 hours and I still have 100% showing on the battery meter. It kind of sucks that the battery meter doesn't start to change until all of the juice is used up on the dock, but it's nice to know that I haven't even touched the fully charged battery in my TF yet after 4 hours of use.

When supplies of the dock become more plentiful, I may buy a 2nd one just to use as a spare battery.
[Eee Pad Transformer Q&A, Help & Troubleshooting] gadgetfann:
It's the stuff running in the background that kills the battery. The account sync stuff especially. ..and then any apps that access the web. My Android phone is the same way.
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Actually, standby battery life is a problem on the TF. I have exactly the same things running in the background and syncing on my Xoom as I have on my TF, and the Xoom uses <1%/hour on standby vs. the TF's 3.5%/hour on standby. Battery life during actual use is about the same, but Asus has some work to do on fixing whatever's killing standby.

And, it's impossible to see what might be doing it on the TF because the battery sensor drivers or somesuch are nonfunctional. I love mine, but I'd sure like to know what's going on.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
Make no sense that it will drain 50% in 5 hours of standby time, the other times I didnt put it in airplane mode and it only drain about 8% in 6 hours.
[Eee Pad Transformer Q&A, Help & Troubleshooting] naturefreak85:
Probably had a rogue app running that was using up cycles on the device.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
Agreed. I left mine at wprk at 745 this am with 60% battery left. Nearly10 hours later i am at 55%.

So no complaints here.
[Eee Pad Transformer Q&A, Help & Troubleshooting] seshmaru:
my transformer with wifi and bluetooth on and connected with pretty heavy (but not constant) use has been unplugged for 7 hours now and battery is at 66% now.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rushless:
People are all over because one person's "light" use is another's "heavy" use, and vice-versa (then throw in what brightness, volume, apps, GPS, wifi, duration of use, etc- FORGET it). Battery life is too subjective unless a controlled test. Playing the same video with same brightness, volume apps, etc, or streaming the same site and content using a full bar wifi signal until it chokes would be decent tests.

added: Normal tolerance is probably +/- 50% across users.
[Eee Pad Transformer Q&A, Help & Troubleshooting] HideYoKids:
Mines been unplugged and on for 36.5 hours, most of the time spent in AP mode. It's at 74%
[Eee Pad Transformer Q&A, Help & Troubleshooting] HideYoKids:
just finished my battery test, I'm about to plug it in now. It's at 22% after 4 days and 4 hours. I've been keeping it in AP mode when not in use. I was worried about my battery life at first, I thought it was a little short. But it just psychs me out because it counts down each individual percent. Now I know it has great life

screenshot below :)
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
I just did another test on my TF, and with wifi set to turn off when the screen is off, I get MUCH better battery life than with wifi set to stay on. Now, this might seem intuitive, but on my Xoom that's not the case. I can keep wifi set to never turn off and still get great life on standby.

My test was: the night before, I kept wifi on and between 12:00am and 8:00am went from 100% to 78% battery life. This morning I set wifi to turn off when the screen turns off, and between 12:30am and 8:30am went from 95% to 92% battery life.

As a comparison, with wifi set to stay on, the Xoom between 8:00am and 2:00pm yesterday went from 48% to 46%. It's now obvious to me that wifi is the culprit here, probably it's not letting the system go to sleep on standby. The good thing is, that's something that can be easily fixed by Asus.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
How many hours of use versus standby? I find battery during use drains more than 10% per hour and if wifi off with stdby about 0.5%/ hour

That means 4 days of use would be 48% used. So to get that performance it would mean only about 1-1.5 hours/ day.

That right?
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
I'm not sure what you're asking, exactly, but I'll say: the TF's battery performance during actual use is roughly equivalent to the Xoom's. That makes sense, of course, given that the Xoom and TF have essentially identical components, including battery capacity. I'd say that if you're using either device heavily, it will burn around 10%/hour and last a total of 10 hours or so of constant use. The TF might be a bit worse because its RAM is clocked higher and isn't the same low-power RAM as in the Xoom--there might be a bit of a trade off of battery life for slightly improved performance.

Mainly, though, the TF differs from the Xoom during standby and only with wifi set to stay on when the screen is off. At least, that's been my experience so far.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Canadoc:
I meant that someone got over four days of use and standby which seems like a lot unless the use was under one hour per day
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
Just wondering at what % should we start to charge the tablet? I read around the net that its not a good idea to go below 30% before recharging it. I used mines everyday and I have to charge it every night. Currently I am charging when it goes down to roughly 30%. Just wondering how low I could go before having to charge it. Also, do we need to full discharge it once a month (draining it down to 0%) before charging it? Thanks
[Eee Pad Transformer Q&A, Help & Troubleshooting] jake21:
I seem to get around 6 hours watching movies with brightness around 50%.

(movies are avi files on sd card; mobo is the movie player); btw can't seem to get mobo to not stretch or the pixels on the asus are not square.
[Eee Pad Transformer Q&A, Help & Troubleshooting] hotelmode:
I've picked up a little knowledge about lipo batteries from my RC airplane hobby, and here's the basics on what I know...

Lipo batteries don't like spending lots of time at 100%, or at 0%. They are most happy at 50%, so if you are going to store it for a long time (weeks or months), drain/charge it to 50%.

If you like leaving it plugged in, go ahead, but drain it down every once in a while to keep it "exercised". This will extend the lifetime of your battery.

Lipos can be charged relatively quickly, and can be drained VERY quickly if there is a large load put on them, but the slower the charge/discharge, the longer your battery will last. This is out of our control with consumer electronics, and isn't usually a problem. They charge at slower rates than they are rated for mainly so they won't explode, but that helps extend their life. It's mostly a heat thing, the fast you charge/discharge, the hotter the battery gets, the shorter its lifespan gets.

You can let your battery get below 30% every day, no problem, but storing it for a long time like that wouldn't be advisable. Same with storing it at 100%. 50% is the sweet spot, so draining/charging every day isn't bad, since on average, it will be near the 50% range.

Charging and draining too many times adds cycles to your battery, which also shortens it's life.

In summary, cycles are good, and cycles are bad. There's some sort of balance somewhere in there, and if you worry too much about it, you won't enjoy your product!

Has anyone tried an app like JuiceDefender with their Transformer?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Zach Alt:
I'm getting 11-14 hours of constant use.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
Try it again last night , this time stop couple of programs before putting it down for the night. It had 78% @ 12:30 am and at 8:30 it only drop down to 75% (airport mode) very happy with the result. :cool:
[Eee Pad Transformer Q&A, Help & Troubleshooting] wynand32:
Ah, yes, the infamous "airport" mode, which offers up overpriced trinkets and bad food (served only with blunt plastic utensils, of course). :)

Okay, yes, putting in airplane mode or even just configuring wifi to turn off when the screen is off definitely will improve standby times. I've confirmed that with my TF, and pointed out in some other threads that the Xoom does not demonstrate this behavior. I think there's a bug in the TF wifi driver that stops it from going into a sleep state and thus it burns significantly more battery on standby than the Xooom.

Other than that, my battery performance has been great.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dazz87:
Hahaha. Actually when it was in airplane mode,my TF would drain about 40% over 5 hours. Now in this new airport mode it goes down only 3% :D

[Eee Pad Transformer Q&A, Help & Troubleshooting] IIJBII:
The TF doesn't have a Lipo battery (that requires a special charger). It has a lithium ion. They are different. Lipo batteries can be dangerous and wouldnt be a fit for consumer electronics like this...I know because I've had one burn up on me.

I'm currently doing a full usage test on mine - playing a 52.5 minute video file with the brightness set to Auto/minimum, wifi is on, headphones plugged in. So far I'm on the 4th playback of the file and it's using about 10% per playback, so I should be getting nearly 9 hours constant use if it continues like this...

My battery only seems to be lasting about 5 hours for some reason. I played Toy Story 3 on mute from 98% and by the time it had finished it was on about 65%

Not sure if i've got something wrong with my battery, but im worried about getting a replacement incase I get a different issue from the excellent quality control from Asus!

Wifi was on, screen on about 50% brightness
[Eee Pad Transformer Q&A, Help & Troubleshooting] ipulaski:
mine dropped from 98% to 14% in about 5 hours :mad:

this is no where close to what I am seeing from others here.

wifi was on all the time, screen brightness is at 100% -- does this have impact on battery life?

My adapter gets extremely hot -- :(
[Eee Pad Transformer Q&A, Help & Troubleshooting] jerrykur:
Screen is the #1 power consumer of these devices. So five hours at 100% brightness is fantastic battery life. They rate it at 9hrs in airplane mode, playing a video at around 45% brightness.
[Eee Pad Transformer Q&A, Help & Troubleshooting] brandonpaz:
Screen Brightness of 100% should cut it to about half, so 5 hours is about right.

The ASUS performed battery test, was movie playback in airplane mode with auto brightness enabled and they got 9h's.

You can check the details on their page for that inf.

[Eee Pad Transformer Q&A, Help & Troubleshooting] M@rtin:
Here's my test results from yesterday - I actually managed to play back that file 10 times with 4% left at the end. I played about with it a bit longer till the battery was at 1% and the total continuous use was as follows:

Over 10 hours so I'm pretty impressed with the continuous use, that's much better than I expected! I'm pretty certain there's nothing wrong with the battery, so it must be something in the software that causes the poor standby battery life. My iPad lasts for over a week with intermittent use, and I'd expect similar from the Transformer. In reality I can't get over 4 days with similar usage:

I'm now trying to put it into airplane mode whenever I'm not using it for a while and will see if that improves things...
[Eee Pad Transformer Q&A, Help & Troubleshooting] jms_uk:
Has anyone experienced a bit of weirdness with the 'WiFi off when screen off' mode resetting itself to WiFi always on?

I ask because after reading the recommendation to use that setting to preserve battery life while on standby in this thread, that's what I did a few days ago.. However when waking my TF up this morning I noticed the battery had dropped a bit more overnight than expected.. on a hunch, I re-checked that setting and it had indeed re-set itself..

The only thing I can think of, is that I got my new dock last night and tried the TF with it.. no lockups or WiFi disconnects but wondering if it borked the settings somehow?

Bought the cord from monoprice, as others suggested, and the cord does not work. Anyone have any suggestions to try? Other than buying another cord? Won't connect to my tv, or computer with HDMI port. Anyone having similar issues?
[T-Mobile LG G2x] Erislover:
You have to push the hdmi cord really hard into the phone. It will connect, but it's a bad design requiring a lot of force...
[T-Mobile LG G2x] kadenstern:
I don't think you can possibly push any harder than I just tried. lol.

Not what you wanted to hear but, I would get another cable. I just got my new one today. I got it off of amazon. Only tried it briefly but worked like a charm.

[T-Mobile LG G2x] Erislover:
That's right -- there is some cable out there frying phones. Search the forum for more threads on that issue. But yeah, the pushing-it-in-harder technique worked for me and a bunch of other people, and I know I thought it was completely connected at first...

anyway, be careful!
[T-Mobile LG G2x] kadenstern:
What exactly did it do to your phone when it "fried" it? Because I had a pretty weird encounter, I plugged it in, at first nothing happened, then it came on to the tv. My phone told me it was at 70% battery but then while it was on my tv, died, after about 3 minutes. I couldn't even turn my phone on, so I waited until it wasn't on fire and charged it and now the HDMI won't work. Seems the phone is working fine though. Similar to what happened to you? I sensed something quite wrong but was kind of just telling myself it wasn't a big deal.
[T-Mobile LG G2x] Amd4life:
would you mind linking the cable you got that worked
[T-Mobile LG G2x] xguntherc:
I didn't have to push hard, HDMI is HDMI.. lol

works great, try another cable.
[T-Mobile LG G2x] Docavelli:
Something similar. I plugged in the cable and I was checking everything out. The cable looked like our was starting to come out so I pushed it down (not hard). All of the sudden the tv screen went black and so did my phone.

I tried to reboot... Nothing. I pulled the battery and smelled something burning. Couldn't turn the phone on after that.
