How to Charge the Tablet and Dock Properly? - Eee Pad Transformer Q&A, Help & Troubleshooting

I just got the dock, I've had the tablet for a while, and I am wondering what the proper way is to go about keeping both charged. I threw the dock on the charger by itself so that it gets a proper charge on its own first (I hope that was the correct thing to do) but I am wondering how I should charge them from here on out. Do I charge both pieces separately? Do I charge them together? Do I plug the charger into the tablet only while docked? Do I plug the charger into the dock only while attached to the tablet? Should I make sure that both pieces are at 100 before docking them the first time?
Sorry for all the questions!
TIA!

Charge them together, I used to charge them overnight but read from peeps that sometimes their dock died doing that so now I charge them both together a couple hours each night before going to bed and it's good the rest of the day. One thing to also keep in mind that I'm gonna start doing is if you leave them docked and sleeping overnight, the dock will lose some charge, like 15% but if you turn the tablet off before then it loses nothing.

by that you mean dock them together and plug the charger into the dock? If that is the case i assume that charger charges both pieces at the same time somehow?

yes exactly

from my experience it looks like the charger charges the docking, which in turn charges the tablet... I don't think the charger delivers enough current to charge both at the same time.

15%? My god are you sleeping about 20 hours every night? For me it's less than one percent an hour, with wifi off...

I turn on airplane put my tablet into my dock and put it on to charge aroudnd 9pm, locked.
I'll take it off around 1am fully charged before i sleep.
When i wake up im sitting aroudnd 97% in the dock.
With the wifi on, i can loose around 40% in the same time.

Just dock the tablet in the evening, plug the charger into the dock, and away you go. There's really no "method" to it.

No, 15% sounds about right.
You can check out this thread ...

But basically I ran the same test and my dock also lost about 15% when connected to the tablet in stanbby over 7 hrs. That's ~ 2% per hour of standby.
This is with wifi on though.
If I power off the tablet completely, and connect it to the dock, then the dock only charges the tablet but loses no charge otherwise.
I should probably try standby and wifi off.

No, 6-7 hours. It's the dock battery draining issue many if not all peeps have, if I turn them off nothing drains. This is with WIfi on, if I turn Wifi off it loses maybe 8-10%.

On another note, yesterday I decided I would start turning the tablet off completely every night, so last night I turned it off when the dock was @ 90% and tablet @ 100%, then I plugged in the power cable tot he dock for about 30 min so it'd be up to 100%. This morning I opened it up and found my tablet was on for some reason, so when you plug the cable in does it power on the tablet for some wierd reason?

Charged for 8 hours, battery only at 96%

I got a Nexus S the other day and so far impressed apart from one thing. I left the phone on charge overnight and in the morning it said it was only 96% charged. This was with it plugged into the mains charger for almost 8 hours with the phone on stand-by.
So I read on a thread somewhere you need to discharge the battery fully, then charge the phone with it turned off to correct this. So I did that last night and again this morning it says it's only 96% charged.
I'm also disappointed at how slowly it charges via the USB cable. Had it plugged in for a couple hours at work on my computer and it only went up by around 3%, this is shocking. I'm trying it again now on a different computer and so far it's only gone up 1% in an hour.
What is going on?
It's meant to stop at 95% - 96%
Leaving your battery at high voltage (100%) will cost the battery lifespan to shorten in the long run. So usually chargers do not charge it to 100% at all but slightly below it to lengthen battery life.
OK thanks for your quick response.
Regarding it being slow to charge connected to a computer, is that normal?
Are you leaving your screen on while charging? Because the screen eat alot of power, so that might be the case.

Nope, it turns off after 30 seconds. Wifi was also turned off.
Maybe try using SetCPU to alter your processor speed during charging and screen off to the lowest. It will significantly increase your charging speed.

I will give that a go. But really should this be something that I have to do, shouldn't the phone charge on it's default settings via USB at a decent rate?
It might be due to programs running at the background. I'm not sure. But my Nexus S charges fast enough though. Not as slow as you mention. Maybe try doing a charge after a reboot of your phone? If it charges faster after the reboot, it is most likely the background processes you had.

Yes it is. USB only supplies 500mA. Plugging into the wall is usually 700mA or 1A. Have you ever seen how long it takes to charge an iPad on USB? Its wall charger is 2A.

No because usb is only half power of regular wall charger, so it takes much longer to charge on usb. It's possible when using the phone during usb charging to pull more power than usb can provide, stopping the charge completely.

I also have this problems, but if don't use the computer usb to charge, it seems no problem.

Why did it discharge, and why won't it charge anymore?

Two days ago, I turned my Infinity off and docked it. Both batteries were fully charged. A few hours ago I picked it up again, and the tablet wouldn't turn on.
I plugged it into the wall outlet. It started charging and I was able to turn on the device. It had 0% charge, and the batteries on the dock were also dead. What I don't understand is: how can the Infinity and the dock discharge completely in that time even though it was supposed to be off?
I left it plugged in so that I could use it while it charges. After some time, it asked me to connect the charger and then turned itself off due to almost dead batteries. Cable was still plugged in, though the charging light was off.
Tried connecting the cable to the dock, no light. Tried connecting the cable to my computer, it didn't work. So, the cable must be faulty, right? I can still turn the Infinity on, it'll boot normally and turn itself off after it's reached the lock screen. There's a red exclamation mark on the battery icon that wasn't there in the first time I turned it on, does it mean anything serious?
I had it drain to zero once overnight. Wasn't completely charged but it was strange... hasn't happened since in fact it generally has very good battery life.
I would definitely try a new cable and or charger.
Yeah, I've asked the store for a new cable. They'll have to mail it to me, so my tablet will stay dead for a few days. Now I know why propietary connectors suck.
Anyway, it seems I'm not the only one that had problems with the charger. Many people have reported overheating, but that never happened to me. The adapter that came with my Infinity seems to be a newer model; the plugs can't be folded or detached.
Charger: I had that happened several times to the SL101. Turned out I had something else plugged into the USB and the adapter was overloaded and tripped. Unplugged for a little while for it to cool down and reset itself.
What do you mean you had something else plugged into the USB?
Anyway, I've left my adapter alone for quite some time. I'll go see if it works as soon as I get home.

I was charging a small 700 mAh battery through the USB. That was enough to trip the AC adapter.

[Q] Wireless charging stops at 100%?

I just bought a wireless charger, and it works great...except it seems to stop at 100%. Rather than keeping it topped off, it will start draining after it completes it's charge (i.e. if i wirelessly charge overnight, it will have 85% battery in the morning)
Thoughts? Is this the way the MAXX works, or is my charger defective?
I believe, and dont quote me but, thats the smart battery in the phone that keeps the phone from overcharging.

If you lose 15% of battery overnight while the phone just sits there, you might have bigger problems than just the charger. But to answer your question, I have the oval shaped Nokia charger pad from AT&T. It will get the battery to 100% and maintain it. If I pick my phone up off the charger after 2 days, it will still be at 100%

The phone when charged to 100%, it will stop charging until the phone reaches arnd 97% then charge back up. And it repeats until u unplug it. It prevents over charging. Also, he is right. If it is at 85%, its either ur charger cannot charge as fast. Or ur phone.

Charging takes ages

I've plugged my Shield into the charger like 4 or 5 hours ago, now I was wondering why it was still charging, so I turned it on and the battery was at 60%, charging.
When I plugged it in, it was at like 10%.
The first charge took quite long too, I was hoping it charges faster by the second or third charge. But it doesn't.
Do you guys experience the same thing or should I try a different charger?
I measured the output of the charger and the results seem to be normal: 5,28V @2,48A

I would suggest trying a different cable and charging with your Shield powered down.
I did charge it when it was completely off, I also tried an other cable and charger and that didn't seemed to help much.
At least.. it's fully charged now after charging it for almost an entire day...
Do what most device owners do.. Charge the stuff overnight and don't worry about how long it takes... Since you are asleep and not using it anyways.
I think is a problem with you HW i mean you have a defect shield, take your waranty and return the shield to the store you bought it, or call nvidia, have you tried to calibrate your battery ? maybe that will help.
how do I calibrate it?
And I'm not sure if I can RMA it because I'm from Europe and bought it from a private Ebay dealer.
New though, not used.
edit: I noticed that it charges faster when its turned on. weird behavior isn't it?

To calibrate a battery such as the one the shield uses, you have to fully discharge it till the shield shuts off. Then leaving it off fully charge it. Do not use it while charging or interrupt the charging.

Anyone else having wireless charging issues?

Wireless charging seems flaky at best. Sometimes, it works like a champ. Sometimes, my phone will stop charging, start charging, stop charging, start charging, etc. until I get annoyed, pick it up, and put it back on the charger. I left it on the charger overnight and found it at 87% this morning. I don't know if it wasn't charging properly that whole time, or if it got to 100% and then just stopped charging. Any tips on this? Anyone else having similar issues?
FYI - this is the Samsung charging pad and the phone with no case or anything on it.
No issues here. Work flawlessly
I'm also having the issue with wireless charging starting and stopping. My charging pad, however is an ebay qi pad. Seems very position dependent on both of the pads I was using successfully with my S3.
The behavior is that it will start charging, then 10 seconds to a minute later stop. Then start....then stop...
S6
I have the sony charging pad and I've noticed my S6 stops charging when I get any kind of notification...
No issues here
you shall use 2A chargers to be effective.
I do. I have an official Samsung 2A charger with an official Samsung USB cable attached to an official Samsung wireless charger.
I haven't paid attention to it throughout the day, but I did notice that if I place my phone on the wireless charger it seems to charge to 100% and then it will stop charging. I know a few nights ago the samsung puck was green when I fell asleep but in the morning when I woke up I was down to 92%. I will be taking the wireless charger with me to work tomorrow so I will know for sure if it stops charging at 100% or if it does what you are describing.
Both my gf and I bought our Galaxy s6 edge on release day at Bestbuy and with the preorder the wireless chargers we're included free. The past 2 nights both of our phones have had this issue. Mine only charged to 87% yesterday and 93% today. Hers was at 88% yestwrday and 96%today.
I'm curious if the wireless charger takes a much longer time to completely charge the device to 100%.
For me better wireless charger than wire... I think I've better battety life.
With wireless charging I use wire charger included.

iirc thats supposed to happen to prevent overcharging.
Does wireless charge work with OTG plugged in?

Thats makes sense but I've my wireless charger next to be bedside table and I was woken up but the charger plugged in notification sound constancy going off.
It would be really great to turn those sounds off. Also, you have to assume that there's some battery level where it will restart wireless charging, right?

This is what I was hoping for when I said above that I saw it hit 100% and then overnight it drained to 92%. I would hope that if it falls below 97% or so that it would charge again to 100% so it keeps cycling but right now I am not sure if it does it.
I've noticed the exact same problem with mine. I got the free Samsung official wireless charger from Best Buy. The phone charges to 100% every night but when it finishes, usually around 3 or 4 a.m., it just stops charging and doesn't start again. So this means that every day when I wake up my phone has drained to around 90%. This never happened with my Nexus 5 on a generic wireless charger. It always kept it topped up until I remove the phone. This is really annoying.
BTW if you go into the settings menu under battery, you can see exactly when your phone stopped charging.

that sounds like the best reason untill i hear anything more concrete, might try charging tonight direct via the cable and see if it hits 100%
but with no replaceable battery they may have introduced this to prolong the life of the battery.
I totally get not overcharging. But it's got to kick back on at some point. Leaving your phone on a charger overnight should basically guarantee 100% in the morning. Maybe at 97% it could kick back on, or at 100%, it could go into a trickle mode. I'm sure some custom development will come along and fix this problem.
Here's hoping for an update or something through soon. Gonna test a full charge before tonight and see if it actually states it reaches 100%
I'll post what I find.
