Hiya,
My keyboard dock battery has always been one to gradually drain regardless of whether my tablet is in sleep mode, powered off or other; this is apparently a known issue, and an update was promised to fix it. I assumed that the 209 dock update was supposed to do just that, and the 3.1 honeycomb update adds a menu option regarding putting the dock in a low power mode.
All that said, with the latest dock and honeycomb firmware, my dock battery STILL drains constantly, regardless of my usage, and then starts draining my tablets battery even if it's turned off and folded up. Do others have this issue or is my dock just naff?
Thanks,
James
no ive noticed the same thing. Then when it does charge it only shows my tablet charging for just under an hour, and it normally takes two hoursto charge with the battery depleted fully. They need a better system which shows the total charge of the battey on the dock and how much extra juice your tablet is receiving fom it, seems weird to me.
My main issue is simply that without the keyboard dock, I actually get a better battery life, which is the opposite of what I was hoping for; I dont use it that regularly, so with the dock attached the battery just drains away while it's off. I think I'm going to return the dock and see if the replacement is any better.
I just want the damn battery gauge for the dock. Then we'll know what's going on better.
This SUCKS
i agree. I separately charged both dock and tablet to full charge yesterday. After charging it was closed and not used all night. Today I used it continuously for 2 hours watching a live stream, and then an hour of playing some games. And I just got a notice that my battery is at 14%. Its hard to believe I can only get 3-4 hours from the TF and dock. This is only after 3.1, so looks like the update is the culprit.

ive been experiencing something really strange since i got my dock two weeks ago......... normally my tf would charge to a 100% no problem and same with the dock........ now even after leaving both of them connected and then charging them over 12 hours........ the tablet first charged to a maximum of 99% then 98% then 97% now 96%, the dock is doing the same thing, and i have charged the tf and dock for over 12 hours repeatedly to make sure that i let the charge trickel in but to no avail,i wiped battery stats and dalvik cache, to no avail......should i be concerned?

I think it's probably normal for the charger to stop at any point above 95%....happened to mine as well and it hangs around 96%-100%..randomly..
oh right .....well as long as it doesnt drop too low.....i thought there might have been some defect or something. anyone else experiencing the same thing as us 2?

I just got my dock today and charged it up fully, was all at 100% now tablet stuck at 97% ish, and dock draining slowly. What will happen once the dock goes empty, does it suck battery from the tablet?
Try using the battery until 10% or less. I have gone until 2% then I let it charge. It went back to 100%.
Similar issues were experienced in my laptop and phone. So I let it drain almost completely before charging.
Same thing happens to mine but I dont own the dock. I never seen my tab at 100%
Hey everyone, so I just got a transformer + dock from bestbuy and so far I'm loving it. I started reading through the stickies to learn more about the device and it seems like a lot of people are having problems with the dock draining the battery.
One thing I noticed about the dock when I'm using it is that it constantly uses its own battery to charge the tablet. Doesn't this mean that I can only use the tablet+dock as long as the dock doesn't run out of battery? Is there a way to stop the dock from charging the tablet so I can get more use out of "netbook mode?"
In other words, is there a way to manually tell the dock to start and stop charging?
Thanks everyone
The battery of the dock discharges only until 3%.
While docked the tablet is charged from the dock. The tablet uses the docks battery for power until the dock battery is empty, then the tablet starts using it own internal battery.
The idea is that the tablet battery is kept charged (or as charged as possible) while docked so you have a full battery on the tablet when you ndock it.
So based on these two responses it's possible to use the keyboard dock all the time without the dock becoming useless after a while? Just wanted to know just in case I need to use the keyboard all day
Yes, you can use the dock all the time, until the dock battery and TF battery are empty

From what I can see, when you have the keyboard dock connected, the dock will still continue to work even if its battery has nearly run down. This is as long as there's enough battery power in the TF's internal battery to power it just enough to use the keys and touchpad. The point it'll stop working is when both batteries are nearly out, in which case just charge them .
So, short answer is yes if there's enough power left in the TF itself.
[EDIT]: Yeah, pretty much what sr-ha said lol .
So if the dock continuously keeps the tablet battery charged even when it's at 100%, wouldn't that degrade the tablet battery? Or maybe I misunderstood, does the dock stop charging at 100% and power gets taken from the dock until it's at 3%?
I appreciate the responses, still a transformer noob

The idea is to keep the tablet at full charge so if you undock it is at the maximum level.
I think the Transformer just uses the dock battery when docked since you don't see the charging icon if the tablet is at 100%. The dock drains until its 3%, then the tablet battery gets used.
Is it really that difficult to understand? The dock charges the tablet. Modern batteries are computer controlled to not overcharge so this theory of degrading the battery by charging it too much or two often is a load of crap. No manufacturer would build anything that technologically stupid anymore. Especially not a top notch company like ASUS.
The dock will pretty much always work as long as there is a charge from something. I've never seen the dock go below 3% so I assume once it gets to a certain level it does draw from the tablet battery to maintain useability until the tablet and keyboard batteries are both depleted.

Exactly what I was thinkin'
I have had my S2 for about 4 weeks now. The internet at home conked out so I have been using the the wifi sharing feature on the phone a lot - like 4-5 hours each day for the last ten days, and since this feature eats up battery real phast, its been sitting on the charger for most of that time, and then some more.
Now since the last two days, the phone doesnt charge anymore. In fact it drains battery whilst connected to the charger. The battery lasts about 2-3 hours now with moderate usage. I managed to get it to full charge when it was switched off and charged overnight for 6 hours. I've attached the results after that full charge
This is after the phone was plugged in for about 20 minutes. If you notice on the right side, the battery is draining while its plugged in!!!! The big drop was reading and sending a few emails, reading some news etc.
I installed some battery monitor apps from the market and they showed the battery being in good health. Any suggestions ?
Try recalibirating it..
let it run down completely and full charge ( don't use when charging) then use until almost dead again ( don not use charger in between) and full charge again.
Seee if that helps or go get a new battery :/
So after a bit more testing, I notice the phone charges at a normal rate when its switched of.
However when its running, then it doesn't charge at all, and over time drains battery, but does drain slower that it would if its not charging.
So one of two options
a) Battery's charge capacity is severely depleted, and is not able to hold much charge. However this battery is less than 4 weeks old~
b) There is something that is absolutely devouring the battery. (screen is what shows up us having used 60% of the battery)
If its battery, will it be covered under warranty? If its something else, how do i fix it. I'm still on 2.3.3 but this seems a bit extreme for the AOS or WIFI bug.

So thats pretty much what ended up happening, it died completely, had to charge it overnight to full charge...and still only lasted a couple of hours.
My guess is that the constant load on the battery running a hotspot has hooped it. Might get warranty support if you don't disclose how you were "abusing" the battery.
Cheap temporary solution is to buy a set of cheap knockoff batteries from Ebay, less cheap is to spring for a genuine Samsung unit. Long term solution is to get your home internet working again.
First step would be to backup all data and factory reset .
That fails i would return under warranty .

Just an update - I removed all the widgets from the home screens and its actually charging now I had the AP widget, the stock price, accuweather, a few widgetdroids, flashlight, photo frame, espn news, touchdown calendar and pulse.
Its not even a month old... and runs pretty damn hot as it is, I dont want to take a chance by using a cheap battery. If i have to, I'll buy an original.
But as far as abusing the battery - its should not be any different than running your laptop plugged into the charger at all times right - how is that beyond normal usage?
After it charges up fully, lets see how long the battery lasts in this 'lite' mode.
Just an update. I'm not sure if was the recalibration suggested by tfn, or removing all the widgets, but i went from losing full charge in 2 hours to losing charge at a rate of 2% per hour under heavy usage!
This is crazy - i think those widgets are taking up way more battery than we think.
Please discuss everything related to battery or charging in this thread
Great! So I got myself thinking about the dock charging situation: Why is it so that the dock charges the pad instead of the pad drains the dock?
In my opinion it is better (or more logical) that the pad sees the dock as rendundary battery and drains it at need. F.e. the pad runs till 50% then drains the dock completely dry and then uses the rest of its 50%.
Btw: I wonder if the dock charging logic is realized with hardware or software by Asus...

Um, at the end of either scenario, aren't you left with the same overall usage time and 2 dead batteries?
And isn't your preferred scenario almost exactly what happens in real world use?
what widgets drain battery?
i know widgets like weather, email, news drain battery because they need to update, use internet connection, so i don't use them to save battery.
but what about "offline" widgets like google play music, clock,... do they drain battery too? they don't update information using internet, but they do update "offlinely" - i mean, for example: google play music, now it shows the song "A", then you open the app and skip to song "B", when you go back to homescreen the widget will show song "B". so it has to update, does this drain the battery?
lol i guess i worry about battery too much, and just figured out that i created the thread "should i use battery saver app", i should have post it in this thread, sorry
and does leaving the charger plugged in to the wall outlet when not charging the tablet harm the charger or waste electricity?

CHARGING/DISCHARGING TIP:
LET THE DEVICE (THIS GOES FOR ANYTHING WITH A RECHARGABLE BATTERY) FULLY CHARGE.
UNPLUG, THEN LET IT FULLY DISCHARGE...ALL THE WAY!-- JUST LET IT DIE WHERE IT WONT TURN ON.
Doing this will increase battery time, decrease battery wear/tear, possible damage done by overcharging.
Do this on a regular basis, and youll start to see it will last longer then 10hrs
Because of this, i run alot of widgets, on performance mode, i have around an extra 30MIN, so 10hrs 30min is my batterys life.
*leaving the device plugged in,charging when its full, is bad!
*using the device, while charging, burns up the battery, youll notice it getting hot.
Picked this tablet up the other day. I noticed that when I took it in the car and plugged it's charging cable into my car usb charger (kengsington powerbolt) that it did not show that it was charging. Is this common? The charge has worked for all the phones I've plugged into it.

I believe you are mostly right, but letting the battery constantly drain and recharging from 0-10% makes it work really hard and it makes in turn the life of the battery less. But in terms of life we are talking about a couple of mins less every half a year or so, since these devices get replaced by new ones every 1-2 years I guess it is ok.
If you want to sustain the most battery life just charge it from time to time when it gets lower than 40%. If you are having problems with battery duration, charge to 100% let it discharge completely then charge again until 100% without interruption. I do the full discharge and charge every month or so.

i heard many people say letting it fully discharge (use until it turns off) and charge back to 100% will harm the battery, (or battery's lifespan). i read many guides online and all of them say this. i asked other people in other forums and they said the same thing.
but i guess you're right that it will improve battery life, in about a half year or a year (depending on how often you charge), then the battery won't be able to hold a long charge anymore. it won't be a problem it you plan to change/upgrade your device next year anyway.
The best battery tips that I use
Remove unnecessary widgets
Use a clean rom
Set your CPU to ondemand and put it on lowest frequency
Turn of wifi when you are not using your device
If you don't need your device for longer than an hour, turn it off
I use it for about an hour during the mornings up until dinner, then it gets a workout and I have never had my tablet die on me, or a need to rush for a charger.
So I had this 910C for a while. Still love this phone but recently the stand by time kept decreasing. This was my second battery but I used fast charging, so I thought what the heck, I will just buy a new one.
Well I did, and the stand by time is just as bad. Almost half my battery is gone by the morning, and the battery barely wants to charge as well. (it's like the phone is cold and the charger is also just lukewarm.)
So what the heck?
Is there a known hardware defect on the Note 4 for this?
Even if I could replace the phone (but why when it works great otherwise), I would still like to keep it around as a secondary device.
Any ideas?
Ps.: Now when I was writing this, my phone also got quite hot but the AUKEY portable charger is cold. My percentage was 16-17 and it could not go higher.
Well, after long hours of charge the new battery does show 100%, but when I make a call the phone gets extremely hot. Like it burns my face.
This morning I watched like 5 minutes of Netflix and that ate ~20% of my battery.
The battery does not get hot, is not bulked up, it's very hot around the main chip...
Using latest Samsung OS btw, don't even have root installed atm.
