So, my tablet fully died today, 0% battery on tablet and dock, and now when I plug in the tablet the screen comes on and off showing the battery with one red bar, is this normal and if not what should I do?

Perfectly normal. It means that the tablet doesn't have enough power to boot up yet, give it ten minutes to get at least 15%. It should boot up automatically after that,
LOL. I've made the mistake of letting mine run all the way down twice. The 1st time it scared the tar out of me and I thought I was going to have to send it back to Asus because it wouldn't come back on after I plugged it in LOL. After letting it charge for about 15 minutes it booted right up. It did the same thing the 2nd time I ran it all the way down too. Even though I know it will boot back up after sitting on the charger for a little bit, I still watch my battery level very closely now. It's a bad feeling when I press the power button and nothing happens!!
Has anyone else experienced very short battery life after the last update? Used to be that if I didn't use my tablet for a week it would only lose like 10% now it goes to 0 in 2 days even if it isn't touched. Only started after the last update. I'm thinking I should do a factory reset just to see if that settles things out.
Or does anyone know of any good battery monitors that can tell you what was sucking all the juice before is died?

Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?
defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?
Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%
Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.
Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.
Ok so I pulled my phone off the charger at 9:50am (it's 7:47pm now) and it says that it's been 2 hours and 12 minutes since my phone has been off the charger. earlier in the day it said 8 hours. Now I know for a fact I haven't plugged it into a charger. Is there something else I could be doing to reset the time on it?
In my experience, rebooting your phone, or turning it off can also reset the battery thing. Just curious to know why would you be annoyed by this, unless you are doing a battery test I don't see a problem about this at all. anyway, that's just my take..
ya I'm trying to see how long my phone can live off the battery. I do tend to reboot my phone once in a while; depending on what cool mod comes out. I will have to see if I can go a whole battery cycle without rebooting.
I have a locked & unrooted WW TF700 & genuine dock on JB 4.2.1.
A week ago I started to notice an issue where the tab would constantly drain whilst it should have been asleep. Overnight it would loose ~30% instead of ~2%. I tried a few settings, but couldn't seem to solve it. I decided to do a factory reset because I haven't done one since I last upgraded to jelly bean. That appears to have cured that problem, but has created two more.
The first problem is that I can't seem to charge the tab over 81% when being charged directly. If I then plug it into a fully charged dock it will charge to 90% but no more, even with the charging cable in the dock.
The second problem is that the tab now decides to shut off at about 30% battery left. It won't shutdown as normal, just go blank and won't boot up again without being charged a little first. I have read threads about artificially overcharging the tab, but a symptom of that is the battery level will remain at 100% for hours before starting to drain normally. My tab won't charge to 100% and will start to drain immediately after removing the charging cable. Regardless I have tried to drain and recharge overnight with the tab both off and on but the tab won't charge past 76% overnight in either case. Restarting multiple times doesn't help at all.
For the first issue I started to suspect the charger may be at fault. This is because if I charge the tab directly, it will never get past 81%. However, if I then plug it into the freshly charged dock it will charge upto 90%. I understand that the dock will never charge the tab past 90%, unless it is plugged into the charger. Does it assume in my case that it isn't plugged in to a charger even when it is? I should mention I am using the original asus charger. Frustratingly I can't just use my phone charger to see if it solves the problem due to the 15v of the asus charger. I have noticed a slight hum/buzz coming from the charger but I can't be sure that it didn't do that before. I have had issues with the internal connections not be pushed together quite right before and getting no charge out of it, but 'clicking it together' a bit more firmly did the trick there.
Even with an overnight charge, plugged into the dock to get it to 90% I now get terrible battery life. Roughly 30mins per 10% juice. Previously I was getting around an hour per 10%.
Does anyone have an suggestions for me on how to eliminate the charger as a problem, or say doing another factory reset on a 'full charge'? The only other thing I can think of is to let it drain, give it enough charger to turn back on, then turn it off and leave it unplugged overnight (I saw it mentioned in another thread). I really appreciate any help you can give before I have to try the dreaded warranty route!
Try this with it undocked. Let the battery discharge to zero, and leave it 24 hours.
Then recharge it fully. This seems to cure the battery calibration memory issues.most us know how you get on.
Luckily I have located an Asus charger to borrow and hopefully find out if it is just my charger or not.
I also tried out CPU-Z and the battery is reporting as only having 7mV. I'm sure that can't be correct as my HOX+ is around 3500mV, and 7mV just couldn't power anything. I don't know if this is just CPU-Z issue with reporting correctly, or a clue that there is something not right with my battery? Has anyone else tried CPU-Z or know what the mV should be roughly, fully charged say?
Unfortunately a different charger didn't solve my issue :'(
I've posted a screenshot to show what is happening. I'll try draining the battery flat and leaving 24 hours to see what happens then. Luckily I still have two months left on warranty.
Pretty annoying because everything else the tablet does is fantastic. I replaced my laptop with it and use it daily for everything.

Unfortunately things have become worse. I tried using the tab until it died (at around 50% battery this time...) and left for 24 hours as suggested. Unfortunately now I can't get the tab to turn on or take a charge at all. I have tried holding power button down, with vol up/down, for over a minute etc. Tried the reset button all numerous times with no luck. All I get is the LED blink twice when pressing the power button and this only happens when the charger is connected, otherwise nothing.
I have the phone number for Asus support and will be giving them a call tomorrow. I'm so glad I never unlocked my device!

Leave it for 24 hours not on charge first then try again. We've seen this happen so many times - the fix is to let it discharge completely.

Thanks Sbdags, I appreciate your response. I've read numerous threads tonight with similar issues. I did try leaving the tab for 24 hours completely dead overnight last night. I'll try it again (I don't know if the battery is dead or not currently) but I'll leave it unplugged as there is nothing else for me to do with it anyway!
OK, I thought I would complete this thread.
After leaving my tablet for a few more days not on charge I could seem to get no life out of it whatsoever so went down the RMA route and the result of that is in the following thread;

I hope I am in the right forum for this...
Lately my two year old tf700t won't stay on for more than 10 mins at a time. I have the dock and both parts say more than 100% charged.
Due to my device being out of warranty and thinking something was wrong with my stock asus rom. I downgraded the rom, rooted it, unlocked and tried several different roms.
My tablet is still turning off even though it says it is 100% charged.
Is my problem a bad battery? I think it has discharged "fully" (to where it warns me) maybe 10 times in the two years i've had it in the dock. It has almost always been plugged in or lightly used around the house. It has never been drained and recharged repeatedly to the point that I would have thought it to be worn out by now.
When I've had batteries go previously, they just drain fast from 100% to 0%. Both batteries are at 100% and it won't stay on but maybe 10 minutes unplugged. When I plug it in, it takes about 5-10 mins before it turns back on again. Meanwhile, the led by the power button blinks orange like the battery is dead. When it turns back on, it tells me I'm fully charged. grr
Does anyone know what is going on? Is there a way to test the battery or is there some chip inside the thing that needs to be reset or something.

It sounds like that you have a calibrations issue with your device. When your device is shut off by itself, you should leave it unplug about a day. Then recharge your device after a day of depletion and hope that it will solve your problem, good luck...:fingers-crossed:
Mhhhh - "almost always plugged in"?
Not the best use for these batteries. 2 years of that could have killed it.... And then - may not have anything to do with it if the battery went bad. 2 years is not an unreasonable life expectancy for a battery for a portable device.
In addition to LMK's suggestion, you could try this:
Let it die and then sit for a day unplugged.
Connect it via USB to your PC and let it trickle charge for 8+ hours (charging indicator will not even come on). Make sure your PC doesn't shut down or go into sleep mode during that time.
It should be charged enough to boot it. Check if it made a difference.
Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
