Hello all,
I am still a bit confused as to how the dock actually works. Since i got my dock this afteroon i charged it up until the light was green with the TF in it and it has been that way ever since; I have no undocked the TF
Is this going to wear out the dock battery quicker? How can i tell? Is there a way to turn the dock off. I find it strange that the owners manual on such a new piece of technology is so limited in scope, it just tells you how to dock/undock it and charge it
It's been stated that the dock battery will charge the tablet battery while the tablet is connected to it.
Of course, when the tablet battery is topped off, the dock battery doesn't charge it. At that point, I'd assume the unit runs off of the dock battery until it's depleted, then runs off of the tablet battery. Once depleted (or discharged a bit, and I'm not sure as I don't have my dock yet) and connected to AC power, I'd suspect the tablet will charge first, then the dock battery.
BTW, did the dock come with a power supply and cable, or do you have to use the one the tablet came with?

no cable with it.
I guess they assume youll be charging them together. the dock bought the tablet from 80% to 100% and it self to 95% in about 40 minutes with the ac plugged in.
Your description of how it works seems to be what i was thinking because the tablet shows the lighting bolt on the tablet even when its at 100% is that good for the battery? Seems to be like the tf loses a TINY bit of charge and it just gains it back from the dock and this just keeps going on.
it's harmless.

all i needed to know. I assume i can use the notification light on the dock to know when its running low.
I heard before that the dock doesn't actually turn itself off; that is if its not connected to the tablet, so it drains its battery while not doing anything. I assume if this is true there would be some kind of firmware that puts it in a very low power state until the dock recognizes something is attached to it.

Actually it is true, and yes it goes into a low power state, although asus has said it's not low enough. They're going to release a firmware update to put the dock into deep sleep when not connected in the future instead of regular sleep which drains about at 50% of the tablet does when the tab is on standby. Of course this update will also bring up the battery power of the dock to about 9 hours since it has the same battery as the tablet.
Sucks that they don't give you another power supply and cable with the dock. I'm gonna have to buy at least one extra. I plugged the cable into my Nook Color charger just to see what it would do. Nope. Won't charge. (at least with the device on... perhaps it will with the device off?)
This means we're going to have to buy proprietary chargers and cables... and I don't think anyone has any yet.
As for the OP, I concur, don't worry about the dock battery. Batteries are like muscles- they like to be used, and don't like to be idle all the time.
As a matter of practice, I try to drain my devices about once a month (run them down to the battery warning, usually 20% or so) and then charge them up again.
http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars has a good description of how Li battries work. Main points are
One of the worst things you can do to a Li-ion battery is to run it out completely all the time. Full discharges put a lot of strain on the battery, and it's much better practice to do shallow discharges to no lower than 20 percent. In a way, this is like people running for exercise— running a few miles a day is fine, but running a marathon every day is generally not sustainable. If your Li-ion powered device is running out of juice on a daily basis, you're decreasing its overall useful lifespan, and should probably work some charging stations into your day or change your devices' settings so that it's not churning through its battery so quickly.
On the other end of the spectrum, keeping a Li-ion battery fully charged is not good for it either. This isn't because Li-ion batteries can get "overcharged" (something that people used to worry about in The Olden Days of portable computers), but a Li-ion battery that doesn't get used will suffer from capacity loss, meaning that it won't be able to hold as much charge and power your gadgets for as long. Extremely shallow discharges of only a couple percent are also not enough to keep a Li-ion battery in practice, so if you're going to pull the plug, let the battery run down for a little bit.
From this you won't harm it through overcharging by leaving it in the dock but you should remove it occasionally and let it run down a bit.
I was thinking about this the other day and I think my planned usage won't be very good for the dock's battery. I was planning to take it to work with me during the day as my second system, and not worry about taking a power cable with me. That is, I figured the dock would power the tablet throughout the day and then when I returned home I'd have plenty of power left for using the tablet by itself in the evening.
However, I think this will basically drain the dock battery pretty completely every day, representing a full discharge cycle. That means the dock battery's lifespan will be severely impacted, even as the battery in the tablet is probably made to last longer (it'll see mostly dips to 70% or so each day, and then recharges).
Maybe I'll have to get a second power cable for work after all, just to avoid killing the dock's battery.

i just checked my tablet on the dock today its been 24 since its been on there and i haven't touched it and now the battery is down to 99% and not charging as it was before did the dock really die that quick?
is there a way to tell what is the battery level of the dock?
I am also very curious if there is a way to determine how much battery life is left in the dock.
Nope there isn't.
Thats not good

Not something Asus can do anything about either, Android isn't made to be compatible with battery docks. This is a completely new concept so yeah.

Yes and no. Assus could add an api so that the battery level could be read. I know that ANT+ hardware is not supported in android, but sony-ericsson have them in there X10 mini and provide access via an api. My guess is that assus will provide support for battery level in future updates. New concepts ask some time.
What happens when the keyboard battery fully depletes, does it just become unresponsive?
No keyboard can be dead gets power through tablet

Only way I know how is to plug it into the charger and look at the light pattern. The patterns are described in the manual. Also if it's not plugged in but drops below 10% the red light next to the charging plug will blink red (Asus calls it Orange in their manual).
I tend to disagree with everyone here.
my tablet has been in the dock for 2 days and the tablet was 100 going in and now its 97% i think my tablet might take into account the battery in the dock too. Theres no lighting bolt on the battery

sorry if I'm coming off as a douchebag but it's plain wrong. Asus themselves have said the battery meter does not take the dock into account.

The dock isn't charged. When not attached to anything the dock still drains power on it's own. Fully charge your dock (2~3 hours) and tablet seperately to make sure they're both full, then attach the dock to the tablet and see if the battery meter starts draining right away.

if no lights are on then it obviously isn't charged and the dock is running off tablet battery power.

Your tablet obviously is going to sleep properly and doesn't have any apps causing many wakelocks when the screen is off. What happens is it drains the dock's battery first then after that drains the tablets battery. That's straight from Asus. What you're seeing is an affect of that. They've also said they are working on optimizing the way Android handles this second battery so we'll be seeing strange things with the meter until then.

I just got my Asus Transformer, I charged it full out of the box for 8 hours as initial charge. Should i drain it to 0 % and charge it for second time? or Just wait until 10 %?
Doesn't matter. I usually charge it when it gets to 10%.
For the first times I waited till 10% or something to fully recharge.
But after a lot of reading about the matter, I have found lots of opinions, so I think it doesn't make a big difference.
Regards.
Alright. Thanks man. Will just charge when 10%
From asus manual:
"Remember to fully charge the battery (8 hours or more) before first use and whenever it is depleted to prolong battery life. The battery reaches its maximum capacity after a few full charging and discharging cycles."
After awhile, Lithium-Ion Batteries don't really care how you charge them, or what their capacity is. Charging a battery at say 50% vs 10% won't really add that much more juice. I wouldn't really concern yourself OP..
Guys, the first 8hour charging means that I must charge separatly 8hours tablet and next 8hours dock? Because I put dock and tablet together and charge it 8hours. Was it wrong? Then I was using it connected tablet+dock together until it was showned warning that battery dropped under 5% and orange LED on the side of dock was blicking. Then I charged it again together and after 5hour of charging, LED is green and tablet shows 100%. Is it OK? Did I do something wrong?
Thanks
One question to you guys: During the first 8 hour charge, were you able to turn on the tablet? Because mine is sitting since 2 hours now and it won't turn on.
I have managed to turn it on.It required to keep the On button for about 10 seconds.

You're fine. The goal is to get the batteries fully charged rather than, say, up to 50% and then stop.
Last I read, LiPo batteries do not need deep cycling to maximize battery life or restore lost capacity due to battery "memory." Some recommend an initial full charge followed by full depletion, but go on to note that is largely to calibrate battery usage stats. I keep most of my LiPo devices plugged in when I'm not using them, because those batteries require "smart" chargers that stop charging when the batteries are full.
If someone has good info to the contrary, I'd love to hear it. But, with well-made devices and chargers, there is no need to follow any sort of careful battery charging regimen. Use it when you need it, and charge it when it needs a charge.

Mine was partially charged and turned on out of the box. Perhaps you have a power button with a loose connection? As long as it's working now, I would not worry about it.
finally today I recive my TR from US,& question is
are all of you guys ,charged 8 hours your TF
coz my is after 3 hours of charging TF is full 100%
& stay like that almost 2 hours more...
should I wait more 2 hours(for calibration reason)
or I can use it now
In the manual, it says charge for 8 hours before first use. I doubt that using before 8 hours is up will damage anything, but why risk it? I'd leave it on the charger.

Thanks for reply. My TF last 15hours of work after second charging. I think everything is OK with battery.

Right in the little pamphlet (that counts as a manual ) under the TF in the box. I'm sure, because it's one of the few times I've read a manual in the last decade.
I´m charging my new TF for the first time and it´s reached 100% after 3 hours. Is it ok to start using it now or must i wait 5 more hours for the 8 that´s stated in the asus-booklet?
You could use it while its charging. First charge is really important. Dont stop the charge

^^ Be patient and let it charge.
I kinda like them always together and then just separate them whenever I want to use the Tablet alone.
Will there be any detrimental effects like the Total battery life will lessen after a long time?
i dont believe so, i run mine that way now, mostly a tablet but every once in a while ill disconnect it and run the batteries to 0 just to get a recharge.

There have been reports of some docks with horrible battery drain. Test yours with these instructions I got in a PM a few months ago from someone representing themselves as from Asus (many other XDA members got the same PM). I RMA'ed my dock after testing and it's been great since.
The following is a step-by-step guide on how to verify if your unit can support the new optional battery saving mode:
(1) Make sure your software is updated to 8.2.3.13 or later; and your mobile dock is updated to 0209. ([Setting]>[About Tablet]>[Build Number] & [Mobile Dock version])
(2) Dock the Pad into the keyboard dock.
(3) Go to [Settings] > [Screen] and select [MobileDock Battery saving mode]
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) With [MobileDock Battery saving mode] checked,iIf your unit still wakes up by a key press, you have the earlier design.
(7) If #6 is true and you also require the new feature, then please contact your local ASUS service center “

I've not really experienced this, so much as in my personal opinion: my phones battery life has lessened considerably since I spent a few weeks of running it down to the at or near the single digits between charges. Can't say for sure though, since what also changed since then, I use it a hell of a lot more too. Now're days I will usually leave it charging if it will be sitting around a while.
My TF, the dock is often depleted or laid low without any real problems; can't say I've done the same to the tablets battery though.

owww.. another question is that would the dock ever lose power while connected to the table?t? ' cause mine still has 3% and it stopped charging the tablet.
In the case of Lithium Ion batteries (which most smart phones and tablets have nowadays, including both TF and dock), it is detrimental to let them discharge to 0% and then fully recharge. It is always best to charge whenever possible, and even leaving your TF plugged in overnight is not bad at all for the life of your battery.

When I first got my TF, I was curious as to whether or not the dock would stop working once it had ran out of battery; testing it, I found the sae result. Dock sticks about 3% and the tablet continues to discharge. I assume the docking connector works both ways and allows powering the dock off the tablet.
I prefer to charge before then though, usually at like 35~19 %. When I undock, I usually leave the dock plugged in to top off, even if it was like 80%.
Hello, I would like to know if there are some "rules" considering charging my phone ? For example, do I need to wait until my phone shuts down or doesn't it matter when I charge it.
main thing is dont play games when charging, everything else is fine. it charges faster with phone off than on
1- don't use it while charging.
2- don't let the battery completely drain (charge when it reaches 15%)
3- try to avoid charging overnight
Avoid using it while charging if you can. Don't drain the battery completely before charging, try to leave at least 10-15% battery before you charge it. Don't charge it overnight as the Honor 8 has fast charging capabilities. If need charged it in the morning, before you get ready for the day.
I don't agree that it is harmful to charge a phone overnight. Once a smartphone is fully charged it has a built in mechanism that stops the charging thus preventing the phone from overcharging.

That's true. However, there shouldn't be any danger of damaging the phone if you do charge it overnight. Either way you decide to charge it should be OK.
Oh okay, one more question; do I always have to charge it to 100% or is it okay to remove the charger at (for example) 58%?
Look if your going to charge the phone do it to 100% But if you need to go out before it's fully charged its not going to do anything to the phone.. Just walk with your charger and charge it when your able to..

For modern batteries, it does no harm to unplug your device before 100%.
Actually it is "healthiest" for batteries to be kept between 80%-20%

While that is true. But there is always a chance that the Lithium Ion battery could become unstable after its been used for a while.
