Hiya,
Previous posts have already mentioned that the keyboard dock battery discharges if the hinge is left in the open position, despite not having a tablet attached (which I am assuming is why my dock seems to run out of battery rather quickly sometimes).
I was just wondering; has anyone noticed the battery life of their transformer decrease when the keyboard is attached and out of battery, as opposed to when the dock is not attached. If I leave the transformer on its own on standby for several hours, the drain only seems to be say 1% every 1.5-2 hours, whereas with the keyboard dock attached the drain on standby seems more like 2-3% an hour or more.
I assume this is because the dock is always drawing power? Does anyone else notice a similar drain?
James,
Yes, i also noticed this ...

I hope a firmware upgrade improves this
I have noticed this as well. I hope they fix this cause I want to have my tablet docked more often.

Yeah but if your not using it it shouldn't drain anywhere near as much battery as it is.
I.e.like if its closed.

With the Tablet switched off and docked the dock still uses loads of power. Very odd.
It defeats the object of having the dock for extra battery life - with the dock attached i get less standby time than without it, which is crazy! I wish they would sort out these issues, until i can rely on it not to drain quickly its just a toy, not something i can depend on.
I'm pretty sure it's been stated before that they are added a fix in a future update.
Hi,
Did anyone notice the noise when the tablet is connected to the keyboard?
With mine, when i plug the Tablet, i can hear a sound like an ultrasound of some sort...

Hello All,
does anybody noticed the increased power consumption after the last official update (3.2.1)? Below is my battery chart after just one day. The most interesting part is when I didn't used tablet in last couple of hours, as you can see no WiFi, screen, pad not awaken and... battery draining as hell. On detailed battery usage screen Android OS was on the top with 38% then WiFi 15% and screen 12%
Before update battery life was ok (My TF is early hardware, stock OS, no root etc.). After update I didn't changed anything, same configuration, no new software, updates etc. Just rebooting two times because tried to get rid of another 3.2.1 bug aka "mobile browser"
I appreciate that Asus is quick to pushing updates to TF, but this time they did it too fast.
Does anyone have a similar problem, or is it just my update went wrong?
I get 7 hrs of hardcore usage, as for a day odds of charge, lucky u, how long where u getting before cause im impressed ;-)

Yeah really impressive, battery from 40% to 0 in just 16 hours of doing nothing .
But to satisfy your curiosity, I had around 7-8 hours of continuous use with WiFi and screen on.
lol sorry for not reading properly, i only got my eeepad on sun and updated straight away to 321, so its all i know at the mo, iv also got a b70 so im patiently waiting for root,

You are going to want to charge your battery to 100 and use the battery calibration app in the market...called battery callibration. Do the instructions it tells you.
You might want to install CPU spy and see what is running in the background to drain your battery like that.

This is a real bug. Here's a screenshot I just took from my tablet. Tell me you don't see something strange with Android OS taking up 26% of the power.
That's 83% battery life left over 4 hours of me using it for about 30 minutes total.
You may want to observe the non-sleeping time using "cpuspy" from Markets. Quite revealing...

Can you see the actual apps or processes running with cpuspy? All I can see is a horizontal bar graph with percentages of different frequencies

You are right. No apps shown. But it shows a bar indicating the duration the cpu spent in deep sleep - this is useful for me.

Right...that's part of the problem with the new firmware..it never goes into a deep sleep. Not sure if it did previously, but the battery life since 3.2.1 is definitely bad
indeed i've seen a noticeable drop in the battery as well and was beginning to worry. hopefully someone comes up with a solution
I have no issues with battery drain after updating.
Did you double check that GPS didn't get enabled? Have you tried a factory reset after updating? Yeah, I know it's a pain in the ass, but it's not so difficult to get everything running again after hard resetting.
Regards.
Hi, I've noticed the same battery drain since the update , just bought the keyboard and was enjoying the added battery life ,but last night the pad and keyboard drained flat in seven hours while it was meant to be sleeping like me. It seems looking at the battery info that the wifi and system never shut down and does'nt even when charging :-(

@CalvinH ,
Good points to check, but I was wondering if you are using the keyboard ,and that is perhaps why some people are not having issues,could it be a keyboard bug again. I will try without and see if there is any difference.

Battery life has not been as good and also when playing music with google music it freezes sometimes and reboots wtf asus
I am getting random reboots as well, after 3.2.1 update. Twice now while the tablet was just sitting there on the table, suddenly the ASUS boot logo pops up.
I have always had problems with ActivityManager killing background tasks a little too aggressively, and so I wondered if it was killing things it shouldn't, now and then. (It does occasionally kill the wifi supplicant process, which should never happen.) But the reboots never happened before the latest update.
My battery life is significantly worse since the update. Before, in 12 hours of sitting idle, it would go through about 20% of battery. Today, it went through 70% in 13 hours of idle.
Wow sorry to hear that guys. For once mine has good battery life again! It was good, then after the last few updates it was reaaallly bad. Now it can go days, but it seemed like it got better right before the update?! Either way its better now.

I noticed today that 3c has updated his Battery Monitor Pro to be compatible with the Transformer.
I am a big user of the Battery Monitor Pro for my Evo and if you are familiar with BMP, then you'll see the benefits.
I placed it on my Transformer and so far I have no problem, it's sure nice to be able to see the mA draw of the dock. Everything else I have tried hasn't given me the detail that my OCD likes to see.
In the Market under Transformer Battery Monitor
https://market.android.com/details?...?t=W251bGwsMSwxLDEsImNjYzcxLmJtdy5wcm8udGYiXQ..
Some Screenshots from my transformer
One thing I am noticing is a drop in recording of the dock, in two separate programs, it shows up in this program and in Dual Battery Monitor, so it must be happening. It drops to zero creating a spike in the recording occasionally and maybe it has to do with Deep Sleep mode. It always comes right back once the dock goes into use, but it is something I am curious about.
Anyone know how the dock is supposed to respond? Anyone else see drops in voltage?
Maybe it's just mine?

damn!i have now finish credits in card!tomorrow i'll buy it!i use battery monitor always from 3c and i can say that is a very good app!curious to see the main difference from this agfadoc!can you explain me in 2 words the difference?
ps..i suppose this app is made only for tf and can elaborate separate reading from the 2 batteries of tf,dock and tablet with the same details of the previous app from 3c?i read in the market few things,but it's not much explained..sorry my english
I've been using this app for quite a long time, on several devices. From your screenshots, it doesn't appear to have changed all that much. I still have yet to have updated it since I purchased it. I like using it to track any anomolies in battery performance.

I can say that the only difference that I can see is Dock monitoring. IMHO if you don't have the dock or need the dock then stay with BMP.
Transformer version- is able to show the total %, total mA or the internal/dock % or mA independently.
Otherwise it's the same as Battery Monitor Pro.

I purchased it today.thanks for the info agfadoc!i can say that it is not so much different from the original app...but usefull for the double batteries monitoring for who have a dock (i have it)
Ok I think I found an issue with my infinity and need some confirmation. Here is the test. Charge tablet to full. I remove from charger and spend 10-15 minutes browsing the Web. Now check battery usage. Is Wifi your number on power drain? Here is what mine looks like.

For comparison I used my xoom tablet for 10-15 minutes doing similar activities and my wifi power usage was around 2%.
Also just an FYI I'm not in a strange wifi environment that creates any issues. I'm about 6 feet from my wifi hub and I noticed this usage today after work where wifi was between 50-60% of my total usage and that was on my work wifi.
Anyway I'd be really interested to hear if anyone is seeing a similar issue. I also created a ticket with Asus asking about this issue.
I hope you know that the stock battery stats are very unreliable. Under a better battery stats app, I've found that wifi isn't quite as consuming as apps, so I think the system stats are incorrect

Your is what I'd expect. In fact you got 91% after two hours. That is better than my xoom. This explains why some people claim good performance and battery life. Mine will be below 90% in like 30 minutes usage.
I think there is a wifi issue and this might be a way of identifying bad tablets. I'll see what the ASUS support people say and post it here. The bad news is this looks like a hardware issue...
Before I completely get excited can you make sure your wifi is always on. Go to settings, wifi, advanced, make sure keep wifi on during sleep is always.

The screenshot is also missing the "ASUS Customzied setting" menu option on the left, right under Apps. Looks like either custom ROM or not an ASUS tablet perhaps.
For what it is worth, I have noticed the same issue with my Wifi eating up tons of battery. I haven't done any tests, but it certainly feels like my battery is draining pretty quickly with Wifi on. It is certainly draining much faster than my TF101....I would expect that to be the case to some extent because of the processor and screen upgrade, but not this much. There is another thread going on TranformerForums about the same issue. Someone reported that leaving their device fully charged with Wifi turned on overnight had drained it down to 19% by morning, with no use.
Not sure yet if this is a real issue, but it seems strange that Wifi would use significantly more battery than Screen.

Don't rely on the battery usage screen. It's not like it's got an ammeter coupled to every battery drain. It just calculates percentages based on the information it got, it's all guesswork and needs lot of calibration to be correct. The reason WiFi is blamed as the major drain is probably that it's running all the time (and its power usage might not be calibrated for the battery usage screen). The stats won't know at all if e.g. the kernel gets stuck in an infinite loop and drains the battery...
Personally, I only trust the info the battery usage screen gives me about apps. If an app has a high percentage, it's probably not right. The rest of the breakdown is mostly bogus.

Well something is eating battery fast.. I have my xoom and my infinity sitting side by side right now and my xoom is at 80% battery after 2:30 hours on while the Infinity is at 62% after 2:41 on. So the infinity is draining battery about twice as fast as my xoom. And the xoom shows the top battery usage as the screen where wifi isn't even making the list.

There are already some threads that discuss this topic. The battery meter has a bit of a bug where it shows the WiFi % based on how long the wifi has been connected rather than how much actual power it has used. Mine does the same thing with 85% battery atm but it has been running off of the charger for 1d 13h and still has 37% left.
It is a battery meter issue and not an energy drain issue.
Xoom is now 68% after 3:30
Infinity is now 50% after 3:40

Well, the Infinity has more hardware to give power to.
However, my Infinity is at 62% after 10 hours... Most (about 80%) of that time, it's been sleeping (but on), though. Did you actively use both your Xoom and Infinity during the reported time?
How does the detailed battery usage screen (touch the graph in the normal battery usage screen) look? Here's mine (the gap is a reboot):

Yes I've been kinda using them. I've had them in google plus and swipe around every once in awhile.
I left for lunch and turned them both off.
infinity is now at 40% and xoom is at 55%. a bit over 6 hours since both were pulled off the charger. Screen has been on over 4 hours.
Here is the current status of infinity 37 percent
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
Here is the picture of my xoom at 53%
From just eyeballing the two graphs it looks like the infinity sleeps better where my xoom is staying active constantly. None the less when the screen is on the infinity consumes power quite a bit faster.
It is clear that the xoom does quite a bit better on battery life than the infinity.
Mine does this too, but battery life is solid

Battery Drain
I just got mine yesterday and the battery drain is unexceptionable. I fully charged it last night and then was off and on it this morning before going to work. After getting into the office it was more than 50% drained and before lunch it was well below 30%. I have the TF101 and it hasn't been charged in two days and it is still at 79% with everything turned on.
I have not had a chance to look into this but I find that amount of drainage excessive.
On a side note I pretty much just have the stock apps running on this. I did just do a cold boot so I will see if that helps at all.

I've had this device since September and I've almost always been unsatisfied with the batter but now it's even worse! I charge it every day just for some slight use and I think it's unacceptable compared to what's promised. Anyone else noticing the same? I've lost 10%/hour and most of the time being idle.
Added a pic as a reference.
Also my device is locked and not rooted.

You could download better battery stat and see what app/process is using up your battery. Also download "wifi" toggle wiget, and turn off wifi, only turn it on when you need it, see you your battery improved. Some reported wifi drain battery heavyly..

A couple of things to think about:
At home, on my Wireless N connection, my tablet lasts even longer than 1 day and a half with light use. I am currently on vacation in Hawaii, and have noticed a faster drain - and here I am on Wireless G. Could be a factor. So could your router itself.
Also, if you create drafts in GMail and save them, the Gmail app checks every 5 min for changes. Don't know why, but it does. I think it is by design.

I have a question, when I have my TF700 connected to mobile dock, I just don't seem to get 9hrs of extra battery life as the dock claims. Also when I close it shut, it 'seems' to go into hibernation properly. But when I wake up the next morning, the battery on both the tablet and the dock are almost totally drained? Not sure what I'm doing wrong.
Sounds like you have a rogue app that is constantly using the battery. What do your battery stats say?
