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.

Thanks! I was afraid 'cause I've heard rumors that if you leave phones charging overnight or if you always have laptops plugged in, the battery life would lessen eventually.
with all battery powered electronics i allow them to discharge fully once a month.

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%.
Hey I was just wondering if its bad for the calibration of the battery to leave the tablet docked in the keyboard all the time?
I dont use the tablet while its charging, i usually always charge it to 100% (while docked), and let the battery drain out completely (while docked) before charging it back up again.
Just don't want to mess up how the battery calibrates or anything (so in the future whenever i use the tablet by itself it won't drain out quickly due to bad calibration)
As long as you charge it to 100% and then disconnect the AC adapter, you won't have problems.
Since the TF has two batteries (one on the tablet and one on the dock), it will manage them both to drain one first and then the other.
The thing that messes up battery life is if you continuosly charge it despite not being drained. Also it isn't wise to let the TF die on battery and then recharge. Recharging the tablet when it asks for it (19-15% of battery remaining) is a good practice.
Cool thanks for the tips, this is my first Tablet (but my fourth android device), and was wondering because i noticed the dock drains out first and then the tab starts draining, but as the tablet is draining, it slowly trickle charges the dock at the same time (so it can still be used).
ex.
TF = 100%
Dock = 100%
then
TF = 98-0%
Dock = 0-3% (once the dock hits 0%, it starts charging off the TF but just enough to use it until the tablet dies)
PS. I created a sugar sync account from your referral so you could get more space lol
Sorry to revive an old thread... but for clarification, should you let both the dock AND the tablet drain before recharging, or is it ok just to recharge as soon as the dock runs out? this way the dock battery doesn't sit at 3% until the tablet battery dies (sometimes a 2-3 days)...
also, how long is too long to leave the tablet/dock plugged in after its been charged? (e.g. if you plug it in before you go to sleep it will be fully charged at least a couple of hours before you unplug it... is this frying the battery?)
thanks and much appreciated!
I dont think that leaving it plugged in is frying the battery, because it stops charging when its full. Also dual battery widget info shows when the battery was charged last time. e.g. last night around 4am plugged in tablet with dock to charge, woke up at 9am, both batteries were 100% (and not hot as while charging) and battery widget showed exact time when it stopped charging, which was around 7am. Rest of the time while plugged in it does nothing i guess

Thanks for sharing your experiences and the logic... That makes sense to me too... However, I do notice sometimes that the charger is quite hot still in the morning.... which makes me wonder. Add to this the whole idea of product life-cycle and planned obsolescence (and things such as internal non-user changeable battery) and I get a bit sceptical... but thats probably just me...
Modern batteries don't like to be drained and last longer if they're 'topped up' on a regular basis. The only time a battery should be drained now-days is if your calibration is off and the software needs to see where the 'top' and 'bottom' of the charge range is.
Also, if your charger continues to charge your battery once it's at 100% you should have that replaced as it's broken.
The old habit of 'deep cycling' your battery is for older style batteries.
If I'm not using my tablet it's on the dock, on a charge. It's fine.
Is there a way to monitor the dock battery?

try 'dual battery widget' available in market... (if this is what you are talking about...)
Or check out the themes/apps section for the official widget from the prime. There's one themed to look like our tf101. That's what I use.

hi friends,
got my tf300 32gb + keyboard dock from best buy, US...rooted it and updated it to .29 f/w......running excellent...no issues
the first charge was done for 8hrs with tab+dock...it is still running great now after 2 days with still 30% juice remaining on tablet and 0% on dock (i store the tab connected to dock, so the tab is slurping off the juice from the dock)
now i want to know ..what is the 'best' way to keep charging this awesome machine...(i know there might not be an 'ideal' way..)
should i wait till the charge in tab goes to less than 10% and then charge it with dock or should i charge them seperately, ensuring the dock doesnot reach 0% ?
how do you guys do it?..just wanna know different thoughts
I just use mine throughout the day, starting around 7:30am when I get up and ending at 10:00 when I plug it in by my bed.
By that time its usually around 45-50% on the tablet and 0% on the dock but keep in mind that I use this as my primary means to access the internet especially at my school cuz the computers suck. It then charges overnight and by the morning its full again.
I don't know if this is the most battery effiecent (ie: long term strength) but it works ok for me and I've never had any problems with other devices that have used the same basic schedule.

The worst part about this practice is letting the dock run all the way down to 0%, because that means a full charge cycle every day. Charging the tablet at 50% or so is fine, though. If you could figure out some way to charge the dock at the same 50%, you'd be in good shape.
Might be impossible given your usage patterns, though. I'd just expect the dock battery to wear out much faster than the tablet's.
Don't think there's a practical way of avoiding running the dock to 0%.
I've read thousands of posts on the ideal way to treat modern (Li-ish) batteries, and so far I lean towards keeping them as charged as possible.
That is - they wear out faster if the're discharged alot to for instance 0%.
The old "discharge to train them" or whatever seems to be either an outdated practice or a myth, and - if I've got it right - outright bad for modern batteries. Which means some companies most likely applaud the practice to sell more stuff.
But I'm not an expert (then again - very few people seem to be).
It's an outdated practice related to the old NiMH batteries from the 80s. If you didn't discharge NiMH batteries to 0%, then whatever percentage you charged it at would be the new 0%. For instance, if you were to plug it in at 50% one day, your battery capacity would automatically be cut in half because the battery would think 50% was "empty". NiMH batteries were eventually fixed, but even then, and even today with Li-Ion batteries, some people think they should be discharged completely.
Also, keeping Li-Ion batteries completely charged all the time is equally as bad as constantly letting them drain completely. Personally, I charge my tablet when it warns me that my battery is low, around 14%.

"as charged as possible" combined with a very mobile device = charging at 20-50% for me.
When I plug my tablet into the fully charged dock, and the tablet battery is below 60%, it discharges the full dock battery within 2 hours. In order to avoid fully discharging the dock as mentioned above, one would be constrained to only 2 hours of netbook type use (or maybe a few hours more if the tablet is fully charged) which defeats the whole benefit of 10+ hours of battery life when using with the dock.
Given this, I believe the doc battery must be able to withstand regular full battery discharges, otherwise Asus probably would have devised a different algorithm for charging.
*The tablet is completely stock, other than a couple apps, like a dictionary and google translate*
I got a Galaxy Tab 2 7 inch a little while ago for school use, and didn't use it much after Spring finals. But when I went to use it today, it would not turn back on. Thinking that the battery had been drained from being left on for an extended period, I plugged it in. What I found was that it would stay black for a couple seconds then show the battery with the stuck loading circle. It then shows the quarter and half charging increments in orange and shuts back off for a couple seconds. I have attached a gif in case my explanation of the animation is not sufficient.
Edit: My problem was purely hardware. The battery had failed somehow, and I fixed the problem with an OEM replacement battery. I'm glad that it was that easy to fix, and I hope that this can help someone else with the same problem.

Thanks for updating the fix, I have same problem battery not charging never though batter would be the problem last couple of charges battery lasted for 3 to 4 hours and my 8 year old son have been using to play games I though getting 3 hours was good for games. Who knows how these new battery function die all of a sudden!!
I will try changing the battery and update here if battery is the issue for me as well.

you charging using direct charging adapter or USB charging?
based on my experience ...
1. If you tab out of the battery to 0%, can not be charged using usb charge for charging low power and not enough ..
2., And if you run out of battery at 0% and you charge using the adapter charges but still can not keep his charge, and so the possibility is still there charging cable / USB you are damaged .. if so you should try to use another cable / new and charging using adapter ..
try it ... I think maybe it will solve your problem ..
