Dock battery drain - Asus Transformer TF700

Is it normal for the dock battery to drain when the tablet isn't connected? I can charge the dock fully, use maybe 10-20% of the battery and then undock it and come back the next day or the day after and it has either no charge or minimal charge left. If I do the same with my tablet and power it off the battery on it stays the same. Just curious before I go and start the tedious return process with Asus if this is normal behavior.

No it's not. My dock holds its charge for weeks if unused.

Weird dock battery probem

I've got the dock for 2 days now. After unboxing, I charged for 8 hrs following manual instructions. Used it with the Pad for some hours (I don't remember for how long) till it ran out of battery, charge for another 8 hrs last night. Then I left it undocked for about half day. As I was running out to a cafeteria, I just docked the Pad (which was in standby state), hop in the car, and now, when I open the pad, the dock's battery is completely ran out, 0%. My dock S/N is B80. Has anyone countered the same problem? What is happening with it? Thanks.

I believe that there are apps in the Market that will allow you calibrate your sensors.... Take a look - let me know if you can't find anything...

I've had some issues lately with the newer firmwares where the tablet refuses to go into deep sleep until it's been rebooted, especially if you leave the browser with tabs open for an extended period of time.
Been using CPU Spy to keep track of it. It doesn't really seem to be related to any specific apps (ran it this way for a week after a full wipe and not installing anything new on both stock and Prime 1.8.4) in that even with a nearly blank slate it will still do this. Haven't figured out why yet but a reboot seems to temporarily fix it.

I have tried to find but it seems there is no apps that can deal with dock battery calibration. Could you help to post the link? Thanks.
What's weirder now is that I undock the pad, charge the dock with stock power cable/adapter, after 2.5 hrs, the dock battery is still empty, red light keeps blinking. Is it a sign that my dock is malfunction?

Well, I found some suggestions in the link below, tried "Cold reboot" and the problem seemed solved, at least for now

Sounds like the issue you have is more to do with the dock not charging over any excessive drain.
Have you tried charging it connected to the tablet see if it fares any better? Otherwise if its still not charging you may want to RMA the dock.
your problem is no problem you can solve. when the dock is connected, the tablet is using the dock to charge its own battery. once the docks battery is depleted, the tablet will be at 100% still. you should still be able to use the dock till the tablets battery dies as well, but with a blinking dock light

so if you're battery is depleted in the dock does the battery need to be replaced? Is there really no other option?
My keyboard and mouse still work fine the dock just won't charge. The orange light blinks and the dock leaches power off the tablet.
I have a bit of electronics experience and I've tried every reset you can do to the tablet with the dock connected and tried different chargers.
The problem seems to be in the port, the computer doesn't recognize is as a USB connection, so it's not even getting power from there. I read somewhere there is an internal switch that causes the battery to not charge. I flipped the switch with the tablet inserted, while charging and not charging and a bunch of different ways and that didn't help it still won't charge. Do I just need to replace the whole battery?
Have you tried charging from an outlet, not the computer ?

Battery drop during charging?

My tf700 sometimes drops to 97% while using it charged, is this normal?
I haven't had this happen, but I wouldn't say it's abnormal yet. Try letting the tablet die, then fully charge it with it off. Then letting it die again. Hopefully it should get your battery back to normal.

Yes. Trying to keep a Li-ion battery at 100% charge all times is bad for the battery.
Yes that's normal. The charger only charges to 100% when sleeping. Every other time it goes to 97% to spare the battery, plus usage eats about 3% anyway.. (Lithium-Ion batteries live longest when kept between 60 and 90%. Fully draining and charging is actually rather bad for it. The only reason you do it once or twice is to recalibrate the battery-level indication.)
It is very difficult to fully drain a mobile devices battery. Notice if you attempt to power the device on it after it "dies", it will notify you the battery is too low, thus the battery is never "empty".

It does go to 100% and sometimes drops to 97% though.

Ah, there we have it. WiFi drains the power like a vampire. (The folklore kind, not the sparkly ones. ) That's what's causing the drops, with WiFi on the battery lasts about 3-4 hours as opposed to 9. Performance mode spikes the CPU from 1.5ghz to 1.8ghz, and that also drains more power.
There's nothing wrong with your tablet's battery.

Wireless charging

I have a wireless charging system, but once the battery reaches a full charge it no longer charges and the battery will start to drain. Is there any way to prevent this from occurring?
I don't know exactly what wireless system you are using but haven't heard of this problem before. I am guessing that it is in the system of the wireless charging and would have to contact the manufacturer to see if they included that option because I haven't seen any different wireless charging options for GS3

It is made this way even tho you plug your regular cord it should drain once full as far as I remember....

But when I charge it with the cord it will hold the charge at 100%. I am use the touch stone mod. It ll charge fine just once it hits 100 percent it will start to drain

I have the LG pad (VZW)and the official VZW back. The issue with mine is the every time you place the phone on it, it beeps and throws a message up on the screen. I stream music while on the pad. Once it's fully charged, it will make the beep, if I leave it on it will continue to beep every 1-2 minutes. Gets really annoying. I have to pull it to the side and let the battery drain down a bit and then place it back on. Another annoying thing is that when it does beep, it cuts into my music.

[Q] Charging decharges w/data on

My phone's battery goes down if it's charging and the data is on until the phone dies. I'm using miktouch and Hyperion's extended battery. It also doesn't seem to charge fast at all (12+ hours). Once it's "dead"it will power off, then randomly go back to 100% battery (orange light to green light).
Anyone else have this issue?

First guess is you have a defective battery. Draining while connected to the charger should never happen with a good battery.
I guessed as much too. These Hyperion batteries go bad quickly. I've had five since January.

I just got mine. It says to not use more than 4.2V to charge it. My chargers are all 5.0V. What kind of danger am I playing with buy not buying a compatible charger?

With LiPo batteries there is the danger of explosion/fire. I have an Anker universal charger and note that the output when plugged in is 4.2V. However, USB ports output 5V, so I would think the Anker battery can tolerate that otherwise you would not be able to charge the phone by plugging into a USB port.

I hope so too.
So, brand new anker and the battery still decharges when plugged in and goes full charge once the phone is off. I'm thinking there's something broken with the phone and not so much the batteries.

From a lot of the comments in this forum, I suspect the phone has a charging circuit controlled by software rather than hardware. Before you do anything hardware drastic, you might try flashing a different kernel.
Also, you report that the battery leaps to 'full' when you disconnect the charger. Have you tried measuring the battery voltage physically with a multimeter to see if the battery is charging at all. Should be 4.2V when fully charged. Something like 3.6V when empty. Obviously if you put the battery in for half an hour and the voltage goes up, it's charging no matter what the UI says!
I've not tried either of those. I don't completely understand what the kernel is. I'm using Miktouch rom, but I don't know how much that has to do with the kernel. I know the battery is being charged because if I leave it plugged in for a good 8 hours it holds its charge for the day. And if I leave it plugged in for say, half a day, and turn off data/wifi, it will slowly show increased charge, like a percentage per half hours of charging.
What do I need to know and do to flash a new kernel on here?

Your the only one of my users to ever have this issue, including me. And the doubleshot was my last device before going Nexus last February.
What I would do is:
1. Backup all your user downloaded apps with Titanium Backup.
2. *Do a full wipe from recovery*
*Wipe data/factory reset
*Format system
*Format Data
*Format cache
3. Flash MikTouch and reboot.
4. Once rebooted don't go cramming apps and settings back into your phone just yet. Make sure its going to charge and drain like its supposed to. If all is well, then start 1 by 1 with your apps, making sure each of them are not causing your issues. If all tests are passed then something in the ROM its self went stupid.
Sounds like hardware though.

Best way to charge your Nexus 5 Battery

Hi all
I will be getting my nexus 5 tomorrow and was just curious if there are ant does and donts with regards to charging the battery. The reason i ask is i currently have a HTC sensation and after 18 months the battery had to be replaced as it was simply not holding its charge. My routine was to charge it overnight every night and use it during the day.
Does charging it through the night cause damage? im just a little bit more concerned as i will not be able to replace the battery with it being sealed.
Thanks for any tips
Chris
Hi,
Take a look here: http://forum.xda-developers.com/showthread.php?t=2511647...
I used to do the same thing with my HTC Incredible... I learned that it can damage the battery over time by not allowing it to hold a charge. Now, when I get home (depending on remaining %) I charge my phone, and unplug it during the night.
If for some reason the battery dramatically drains overnight, I'll charge it when I'm getting ready to leave in the AM.
That is just my method, but I have had great results with it for my usage.
Plug it in...

I have had this phone since it was announced. I plug it in every night when I go to bed and leave it plugged in till I wake up. My battery is fine. I have done the same with my note 2 also. Never had any problems

It's not hard to pop the back cover off and replace the battery when it goes bad. I just dont worry about it and charge whenever and take it off the charger whenever.
