How does the charging from the dock go? - Asus Transformer TF700

Hey guys how does the charging with the dock happen? I'm asking cause I always wondered what it was like.
Does it just drain the keyboard of battery first (While plugged in, dock will always be supplying power first until it's drained) or is there a sort of balance between the 2 (dock kicks in at a certain percentage or something)? Cause by always draining the dock first, the battery in there will get damaged right? It's not exactly explained in the 201 manual (I downloaded it to have a look heh).

I've witnessed a balance from mine. The keyboard charges for a while, then it doesn't. I haven't figured out the rules yet, but it does make sense. You don't want to completely discharge an lithium ion too many times.

As long as you keep it in the dock, I think it will drain correctly and you'll reach the end of your battery in both devices about the same time. Or you won't, and you'll have battery all day long

[Q] Apps to stop battery charging at certain percentage?

are there any apps out there that could stop battery charging when the battery is charged up to etc. 80%? thanks

I too would love something like this - Something that would stop charging at 99% so that stupid damn popup box (Please unplug your phone to save energy) doesn't pop over my clock and stay on screen ALL NIGHT.
Unfortunately, i'm pretty sure that the charging is a hardware thing - so i don't think there's anything out there that can stop it short of unplugging.

if your trying to make your battery last a long time just plug it in before you hit 20% charging to 100% is not going to be a big deal. today's li-ion can take alot of abuse just dont drain them dead and expect them to live very long
Yeah I wouldn't worry about charging to 100%. I have over a dozen lithium batteries for my flashlights, and I keep them all near 100% most of the time.
Charging Li-ion battery above 4.2v is bad.
This app you asked about is very important. Charging a battery more than 4.2 volts dramatically shortens its recharge cycle numbers. I measured my battery volts, found that 4.2 volts is achieved around 85%.
An app that would prevent charging over 80% will be great.
Thanks.
Any news, any app which stops charging at 80% ?

You all make foolish observation based on you personal use of some batteries, of course this is not a reliable info.
You learn in basics of electronics that there is a quantity of energy that it is supposed to be put in a battery for storage, extending it's battery life, and also. Cientific studies show that maintaining your battery near this spot is healthier, so the app wold be pretty useful.
And no, comments like "I've had plenty of batteries, I make bad use of them and after a year they're just fine" doesn't disqualify cientific research.
This apps works awesome! Until this week, when the latest March security update came out, and broke it for Nexus's...Nexus'...Nexi...? lol. But it might work perfect for you if you are not on a Nexus, or if you are, and you're not on the new march update, you're probably fine!

Oops, I spoke incorrectly. It was NOT the march update that caused it to stop working. It works fine, it was another app causing the conflict. I should have corrected this post sooner.

issues with TF700

I have the infinity since three days now. I have the 64Gb version that came with the keyboard dock, it appeared the be a prime dock also.
Now after a couple of days it seems to have a few issues. First of all, automatic brightness is very buggy. Either it's way too dark, or way too bright. Also, moving from dark room to brighter room doesn't change brightness. I have to set it manually all the time.
Second and more important, i have trouble with the charging. when both tablet and dock are fully charged, and i use the tablet seperate for a while, the moment i plug it back into the dock it starts to charge through the docks battery. However it doesn't charge untill 100 percent, it stops charging at far example 78 percent, while i still have 30 percent remaining in the dock. No matter how much i take it out of the dock en plug it back in it wont charge anymore. Untill i restart the tablet and then it charges again.
Also when both tablet and dock are fully charged and i keep them docked, it starts using the tablets battery and not the dock's like it should be. So my dockremains at 100 percent while my tablet depletes.... very strange. I also have my old TF101 so i know how it should work.
Any body also having this strange behavior?
Will the charging is normal for safety measures it happend on my tf300 and prime as well, and believe it or not I returned them both and ordered an infinity

Same problems for me. I contacted Asus tech support regarding auto brightness today, they said it's the same with all Infinity tablets and no solution yet. Regarding charging bugs - I just noticed them today.
Also it's extremely annoying that while downloading something bigger tablet becomes almost totally unusable and unresponsive - I think that's I/O problem someone already mentioned in other threads.

edit: it just happened again, at 87% tablet stopped charging, with 73% remaining in the dock. and now tablet slowly depleting. They were docked all the time. only when connected to wall charger, they both charge to 100%
Hi @all,
can someone confirm the following?
I get the feeling that the tf700 has some kind of secondary auto-brightness!
I've turned off the auto-brightness and set it to ~50%, IPS+ off.
When I switch from a browser with a blank page to the homescreen, I can see that the brightness gets adjusted a little in very small steps.
You can see it with the default wallpaper (the one with the tree on the hill)
Switching back to that blank page shows these adjustments too!

+1, it's dynamic contrast, I can see it too on my Infinity with auto-brightness off.
My TF700 has these small adaptations in brightness as well. I do think they help visibility a bit.

Well I just got mine and still doesn't charge fully from the dock but I'm fine with that

With regards to the dock, its designed to alternate. So it'll deplete a bit from the tablet, and then from the dock, and then from the tablet and so on until the dock is out. At least, that's how the Prime and TF300 were set up.

On my TF700, the dock is depleted first (I'm currently down to 15% (dock) and 72% (main). I have indeed heard before that previously the design was to let them deplete more or less evenly, but I'd wager they have changed that behavior to enable the tablet to be decoupled and have the best sht at having a full (or at least mostly charged) battery. I think that's a logical setup and I think I prefer it this way. With the risk of carrying this slightly off-topic: how were your experiences with the previous setup?
Suddenly i also got the screen brightness problem. Was doing fine the first two days.

you're talking about previous setup. The TF700 is brand new? Which firmware do you have on your tablet. Mine is alternating, but i would much prefer the other way, which depletes the dock first. I'm running 9.4.5.21 and dock firmware 0207.
I don't own any other Asus tablets, so I have no idea what "the norm" is, but IMHO it makes much more sense to use the dock as the primary source of power (similar to plugging it into an A/C adaptor) first, and only switch to the tablet's battery when the dock's is depleted. This way if you use the tablet+dock for four hours and then take the tablet out of the dock to use independantly, it will still have a full charge.
The only thing I can think of as to a reason why it would try to use both simultaneously (albeit alternating), is if the tablet wasn't able to power the dock and the dock itself needed power for both itself and any accessories plugged into USB ports, etc. If that's the case, then if your dock ran out of juice, your tablet wouldn't be able to use it anymore, making the battery life only ~4-5 hours before you had to remove it.

I've never actually owned a Prime or TF300, I just remember reading that in a review for the Prime. Sorry about the confusion. Having it fully drain the dock and then the tablet does sound like a better solution.

I have the same firmware versions as you but it depletes my dock battery before tablet. Currently dock 43%, Tablet 80%. As I type this it changed to dock 43%, tablet 78% so I guess it doesn't exclusively deplete the dock first which makes sense too.

When can i use it?

Just picked my 32gb gray tf700 from best buy and plugged it in the charger. So when can I turn this thing on without having to worry about battery issues.
ASUS said : "Wait 8 hours".
Some people can't wait, but I did. I don't know who is right, because there were many discussions about battery technology, and we still don't know who is right.
I turned mine on immediately lol
I only used it for a couple minutes before shutting it back off and charging it for the night

Mine was turned on immediately also. The tablet had about 30% battery left so after letting it recognize my local network as well as my google stuff I put the charger on it and powered it down. As soon as the charging light changed to 'green' it went into my TF201 Dock keyboard which while booting up did an upgrade to my TF201 Dock from 206 to 207. Have never looked back since.

Tablet charges within 3 hours. Once it hits 100% it stops charging the device. So leaving it on for an extra 5 hours makes no sense. A green indicator will also let you know when it is near or completely charged or just look in the notification bar.

Is there a way to stop the dock from charging the tablet?

I heavily use my infinity with dock. I know that Li-Ion Batteries have degraded battery life every time you let them dissipate to 0%. Unfortunately that almost always happens when I use the dock (Tf201). Is there any way to stop the tablet from charging from the dock around like 5%? I want to keep my dock connected because I want to keep using the keyboard but I don' want to shorten the dock's battery life unnecessarily when my tablet is at 90%.
Is there an app or rom solution to this?
Sent from my ASUS Transformer Pad TF700T using xda app-developers app
same problem here. my dock drains fast too i feel like its giving it too much power !
Same. Mine charges the tablet super fast, but the dock still works at 0%. I've only gotten it there one though.
Same here, I feel the dock is charging the tablet just a tad too much. When the dock's warning me about 0% battery left, the tablet itself is still at 80-90%. That can be useful if I wanted the dock to ONLY charge the tablet, but when I want to use the dock as well, it's far from ideal.
I'd like it if we had a setting for this, like one for pretty much just using the dock as a spare battery/charger, and one for maximum tablet AND dock battery life. I get that the dock's not much use without the tablet, but it feels unbalanced as it is now.

Because for Lithium-ion battery it is not good to have it discharged to 0%, this can reduce the battery life span.
Also another problem can be is when battery is a discharged state, its voltage will gradually decrease then the keyboard dock will no longer be charged any further because the protection circuit disables it (Although this usually applies when you are storing the battery at discharged state but its a good idea to keep this in mind).
Cheers
Actually, the dock battery is not fully depleted when it reaches the nominal zero % charge -- the internal electronics of modern batteries prevent them from depleting to harmful levels. (This has been referenced in the TF700 forums elsewhere, by the way, which a search probably would've shown.)
I think that the charge provided to the main tablet is coming from both the dock battery and the main tablet's battery at the same time; however, since the dock battery has a significantly lower capacity, it should not come as a surprise that it gets 'depleted' sooner.
From a usability or design point of view, I fully agree with you that it would have been nicer to see the dock deplete to about 40% 'resting charge' (which is reputed to be the optimal moment to connect the charger again ) an have the tablet's main kick in. The dock battery could then take over when the main battery reaches 40% charge left. That way we'd have best of both worlds: battery capacity is used optimally, and battery life would be optimal as well.
Alas, this is the real world. From a practical point of view: do not worry you are screwing up your battery, as you're not. Well, of course you are, but all batteries degrade when in use; that's a given -- but when our batteries finally die on us permanently and irreversibly, we'll have at least one other great 64-core 256 GB superduperHD 30" hypertablet available that makes you fresh coffee in the morning, irons your clothes and tells off door salesmen on its own. It will be so heavy it will need legs of its own, but then it also runs all Olympic sprinting distances at least an unbelievable 2.4 seconds faster than the then-current world records.

This ^^ is right, though -- if you wait long enough, even the protection circuitry will fail, and the natural voltage fall-off will kill your battery. If you put away a healthy Li-Ion battery in a fully charged state, this should take about four months at the least, but probably closer to eight months to a year.
I hope someone reads this and decides to create an app that exactly handles this problem. I feel bad when I always discharge to 0%. If this is not so harmful as I feel, I still I dont like it.
I think this is a mental thing for you all. No need for dock to keep a charge. Its designed to push the tablets life longer so you can detach it and keep going if you'd like and not leave any juice behind.

It's not quite as simple as that is it? If it was just an extended battery pack why have a keyboard, USB port and SD card reader included?
Okay, you only see it as an extended battery, not all of us does. Part of the reason why I chose the TF700 is because of the dock. Any portable device can get a portable battery pack to extend battery runtime, this one is a keyboard and port extender as well.
I don't see why we shouldn't be able to further control how the dock depletes its battery, it'd make it a lot more useful overall.

Then leave it attached, makes no difference. Add the numbers up to 200%.
If you have 80% battery, what difference does it make if its 0% and 80% or 40% and 40%? (I know battery sizes are different and percentages would be different).
Now overall battery is down to 80%, if you detach tablet with scenario 1, you have max battery left (80%) vs 1/2 of that (40%) if the dock had a charge remaining.
Why should the dock keep any charge? It still works with 0%.

because some of us do not want to let it waste charge when the tablet is already near full. (save some charge for later). we dont want to recharge it just because it gave too much power to the tablet at an uncessary time. i bet alot of people dont want it to charge the tablet to 100% from 99 everytime u turn the screen on lol , it would just make life better with the tablet + dock if we could control when it does charge during sleep ,ect
I'm trying to understand what the problem is here... What good does it do for the dock to keep a charge? You can't use the dock without the tablet and as long as the tablet is connected, the dock will work, even if it reports a 0% charge. So what good would it do to keep, let's say, the dock at a minimum of 10%? That 10% would be completely "wasted", right?
Or am I misunderstanding the issue?

I was under the impression that the dock will eventually "power off" and you won't be able to make use of the keyboard, USB port and SD card reader once its battery is depleted. However, if they're still fully functional as long as the tablet is connected, I don't really mind the current way it's done.
Surely the dock requires some power to operate though, and unless it gets that power from its own battery, the tablet will have to power it. It's this "obfuscation" of actual battery capacity and use I find slightly annoying.
After reading this thread and after some thinking i can dig both camps :laugh:
On one hand, we are concerned about a battery lifespan, and as it is well known that batteries should not deplete to 0%, i can dig those who want to control that. But, there is also a mention that the battery doesn't really go down to 0% and it somehow controls that automatically.
So, no worries on this side.
The other "problem" - which i think is more important, at least to me - is that some of us feel that it is completely unnecessary for the dock to charge the tablet if the later has 99% of battery. I would also like to have some kind of control over this.
Both 100% - i want to use only tablet battery. And i will use it until it drops to about 30-40%. Than i would like the dock to kick in and refill my tablet. Probably right in the middle of my other work when i actually don't use a tablet (faster refill as i am not using it). Well, after it reaches 90%+, please docky dock, get out of the way and wait for your next turn. Maybe i'll refill you, too
So yeah, there is actually NO problem at all, only different use cases. I bet every single one of use has a little bit different usage pattern and with an app to customize these things, we could and should all be happy.
Anyone, anyone? I would like to beta test it

I'm trying to understand what the problem is here... What good does it do for the dock to keep a charge? You can't use the dock without the tablet and as long as the tablet is connected, the dock will work, even if it reports a 0% charge. So what good would it do to keep, let's say, the dock at a minimum of 10%? That 10% would be completely "wasted", right?
Or am I misunderstanding the issue?

The issue is that Li-ion batteries lose max harge every time they are depleted. You do not want to constantly cycle your battery because of this. The dirty solution is to stop using your dock before this happens but i use my infinity for work and this is not an option.
Sadly after only about a month of use my dock maxes out at only 98% now after being forced to completely dicharge it while working. At this rate, I will lose almost a quarter of the dock's charge in a year. Thats completely unacceptable. For such an expensive device.

Inverted battery priority when discharging

OK. The title is probably confusing but here are the details. I'll be running my tf700 with fully charged dock and tablet while it is docked. Well, the tablet's seems to be the main battery used; it drains while the dock battery remains 97%-100%. Has anyone experienced something like this? Does anyone know if the performance/balanced/power-saving modes have any say in which battery gets used first? Thank you.

Yes, that is perfectly normal. As soon as the tablet battery drops to lower than about 70%, the dock will start recharging the tablet.
Ah, good to know. I did notice it start charging. I was confused since this behavior is different from my tf100 withthe dock.

I just checked mine and it started with the tablet battery first, but when it reached 89%, the dock battery kicked in and recharge the tablet battery.
Mine does it at 70% as well.
Sounds like you got a better one buhohitr!
Same here as well.
