TP2 low battery, in reboot loop

I've got a TMOUS TP2 which appears to be stuck in a reboot loop of sorts cause I can't charge the battery.
I've read through the forums and I saw a few similar problems like this but it seems like it those they were stuck at the bootloader, and that's not the case for me.
Basically the battery was down to 14% and I turned off the phone last night intending to charge it this morning. Somehow the battery dropped to 1% by the time I went to turn it on this morning, and it shutdown (really just lost power) right after I started it. So I go to plug it into the wall charger and then:
charge light comes on
after a few seconds charge light goes off
the phone tries to boot (does little vibrate, shows splash)
after the splash screen, phone loses power
charge light comes back on
then tries to boot after a few seconds.
repeat
If left unplugged the phone just sits there dead, but upon plugging it in, it tries to boot.
I've seen it where the phone doesn't have enough power to boot and just needs to be charged for a while, but I can't seem to do that here.
Anyone have any idea how to prevent it from trying to boot after the AC adapter is plugged in?
Thanks

If you're desperate...you might try doing a hard-reset.
Why would that help? I don't know...except sometimes when really stuck it helps to just change the situation...try something completely different.
Of course, a hard-reset deletes all data and applications that you've put on the phone, which is why I suggested it as a recourse if desperate.
Probably keep the phone plugged in while doing hard-reset.

Same problem, solved by itself
Hi,
I had a similar problem with a standard TP2, it was clear a battery fault. Phone was working well with a new battery and, of course, another working phone couldn't boot up with the faulty battery.
I took out the defective battery and let it aside for almost 2 weeks. After that it started to work, but the capacity is clearly smaller.
So from my experience, a hard reset wouldn't help you.

Yes, it goes without saying -- though it's good you did -- that if you have access to another battery that's an obvious thing to try first.
The hard reset is worth trying, in general, for otherwise-unresolvable phone issues.

It's a dead battery. Same exact thing you describe happened to me. Granted, it was because of water damage but same symptoms. Thinking the phone was dead I went and bought a new one. Then I decided to try the new battery, bam, phone back alive. Returned the phone and bought a new battery. By the way, the dash2 battery fits as well. Tmobile stores didn't know it... But the connectors were the same do I tried in the store and it worked.

So it was indeed a dead battery. Oddly I found someone who had a CMDA TP2 from Verizon (mine is GSM TMO), and was able to pop my battery into their phone for a minute or two and charge it to about 5%, then put it back in my phone and all was well. With their phone, plugging in the charger did not cause the phone to start up and then power cycle.
That's really weird "glitch" if you want to call it that. So mental note, don't let the battery run down too far.

[Q] Galaxy Nexus wont turn on or charge

My Verizon Galaxy Nexus will not turn on or charge. I put it on the charger Saturday night with ~10% battery left. When I up in the morning my screen was black and the phone would not turn on. When I reconnected it to my charger it did not indicate that it is charging.
I have tried 3 different batteries, chargers, and cables. When my phone connects to a charger or computer it doesnt respond at all, no charge light. When I connect it to a computer, the computer does not acknowledge my device at all. I thought this could have been related to letting a battery fully drain so a bought a seperate battery charger, a full battery has no effect.
I am running the latest Bugless Beast (released 10/10) which I flashed on release day and haven't had issues with. I have restarted my phone several times since flashing so I don't think this is os / app related.
Prior to starting this thread I been googling this issue and none of the suggestions that work for others seem to fix my issue. Please post any suggestions you have including the risky ones. Verizon is delivering a new Galaxy Nexus Thursday and I'd like to get my data off and un-root before returning my device, if possible.
Thanks

I am in the same situation now. I just took the phone, went to wifi settings to connect to a new Wifi network, and it got stuck there. I waited for about 2 minutes and then pulled the battery. After that, it won't turn on or even charge.
Really pissed with the fact that how brittle these darn devices are.

Galaxy Nexus sporadically not charging, fast battery drain

My wife and I each purchased a Galaxy Nexus from the Google Play store last July. Recently, my wife's phone started only charging sporadically when connected to a charger. The symptoms don't line up exactly with any other situation I've found described online, so please bear with me while I type out a full report.
I tried removing the battery and using a precision screwdriver to "nudge" the micro USB port "tongue" toward the screen. I thought it had fixed the problem as the phone started charging immediately after I plugged it back in, but when I checked it ~30 minutes later, it had stopped charging.
I tried taking the battery out of my GNex and putting it in my wife's phone; I put my wife's battery in my phone. That seemed to fix the problem, though, again, it was only temporary. I was able to get both batteries to charge to ~80%, then swapped them back. Again, my wife's phone charged the battery, but only for a short while. I swapped batteries twice more to rule out a bad battery; the same symptoms persisted, so I can confirm the battery is not the culprit.
I tried cleaning the micro USB port by removing the battery and using a needle and 91% isopropyl alcohol to clear any dirt or dust from the contacts. I waited for the alcohol to evaporate, reinstalled the battery, and plugged the phone back in to the charger. Same result as before: Phone charged for a little while, but stopped charging before reaching full charge.
We tried 4 different USB chargers: The charger that came with my wife's GNex, the charger that came with my GNex, the charger that came with the Droid RAZR MAXX that I use for work, and the charger that came with my wife's Verizon Jetpack. Same results on all chargers.
Now for some oddities:
The "charge for a while, but stops charging after a while" persists whether the phone is on or off. I turned off my wife's phone at bedtime one night, plugged it into the charger, confirmed that the charging icons appeared (a lightning bolt, then an animated charge meter). When I woke up, the phone was still turned off but only had 13% charge.
Whenever I plug the phone in to my Windows 7 laptop, I'm able to access the file system every time (100% of the 4-5 times I tried). The Battery settings page will say "Not Charging," but I can view and modify files using Windows Explorer without issue.
And now, for a note from my wife:
Unless my memory fails me, I think this was one morning when the charger felt warm on the adapter where it plugs in. Pretty sure this was the day I took the charger with me to work. I had the phone turned off and plugged it in and later turned it on to check the charge and it had been charging. I left it on and it continued to charge. I had to unplug it on three separate occasions and I plugged it back in and it did ultimately charge fully. But when unplugged, the battery did drain quickly, and I had not previously had a battery life issue.

The phone will sometimes get warm--not hot, but warm--around the area under the camera when charging. (I'm guessing it's near where the battery makes contact with the phone.) The charger itself will also get warm sometimes.
Sometimes, even though the Battery section of Settings will say "Not charging," the battery would charge very, very slowly (as in, an increase of 1% charge over the course of 15-45 minutes). When plugged in, the battery would sometimes hold charge (e.g. stays level at ~45%) but not charge or discharge.
When I called Samsung support, I waited less than a minute to talk with a person, explained the situation and symptoms, and was told, yes, the phone is out of warranty (by two months, which I admit is aggravating), but I could send it in for repairs for a total charge of $70.63. That includes shipping both ways. Total repair time would be 5-7 business days. Add 2 days for shipping each way and my wife would be without a phone for 9-11 business days if we were to send it in. It's good to know that the repair are (in my opinion) reasonable because I was hoping to hold on to my phone for at least 2 years before upgrading (and I'd prefer to wait at least 3 years).
I've since got an old iPhone 3GS working on Straight Talk (which was its own ordeal) so my wife has something she can use if and when we send in the phone for repairs. (Side note: My wife really misses Swype.) She plans on backing up her data tonight so I can wipe and reload her GNex and attempt to rule out software and OS as the root cause.
In advance of wiping and reloading my wife's GNex, I had a few questions:
Do you agree with my hunch that the root cause of this issue is hardware, not software? I'd love to be wrong, but all evidence points to a hardware fault.
What ROM do you all recommend for thorough testing in this situation should I encounter the same problems with a clean Android 4.3 stock install?
Are there any other possible fixes you all could recommend before I drop 70 bucks on repairs and my phone has to tolerate the iOS on-screen keyboard for 2 more weeks?

I've had this problem once, I even changed ROMs and it never went away. I changed my charger and it still did the same thing. I don't know what fixed it, but it just started working normally again.
What caused was that I was using it and my device got really hot because I was downloading things, browsing on the internet and playing games on it all while I was charging it. My phone got really hot and a little "CLICK" sounded off and my phone just shut off. It wouldn't turn on until I removed the battery. Cooled it and charged the battery overnight. Although my phone was working now my charger was crazy.

Not charging, screen flickering

I bought a note 10.1 2014 Ed a couple of weeks ago on eBay. Not refurb and sealed in the box.
Devastated to find tonight, after completely discharged and shut down, that it seemed not to charge at all.
It becomes stuck on either the battery symbol, where nothing happens, arrow doesn't spin and no animation, or goes to the device model name. All the while the brightness flickers.
Have tried various chargers, I've taken all the cards out but nothing is working
I think it may be a loose connection with the battery (but open to other theories).
If anyone has had this problem, how have you fixed it? Is it worth disassembling and trying to fix it myself (as I'm sure you can tell I don't have a lot of knowledge about this)? Being an eBay purchase is it still under warranty with Samsung? How much would a fix be if it was a loose battery?
Thanks in advance

As far as I am aware items from ebay are not covered under warrenty.
Even with the screen off and nothing happening, leave it on charge for few hours then unplug and try to put it on.
Also have a look into the charger port of the tablet at the bottom to make sure nothing looks bent or out of the ordinary.

shame i always liked samsung over apple.. and bought a product with no support.. apple atleast accepts product bought anywhere in the world and even replaced battery for my frnds iphone 5s when in warranty...

I have not had this issue with my Note, but my Nook did the same thing once. I disconnected the battery for a few minutes and everything reset. No idea if this will help, or if you are adventurous enough to try it.
Here are some pictures of the Note tear down. http://forum.xda-developers.com/showthread.php?p=49595697

samsung sm-p605 dead not starting, screen flickers
i am going to try removing the battery as u said.. lets see..
anyother ideas plz let me know..
but shld i do this quite often?? is this an known error of note???.. do we have this problem when complety drained????

samsung sm-p605 dead not starting, screen flickers
no luck.. i removed the battery from the board, then plugged in back after couple of minutes..
still in same state..
the screen flickers a lot.. is that normal when the note is completely drained..???

It is very bad for the battery to go completely down. I don't let it happen on my devices, so I cannot say if the flicker is normal.
My experience with the Nook was actually a friend's device. He had let it run down, and it was not charging. He left it on the charger for a few days, and it was still not showing a charge. He gave it to me to check out. I disconnected and reconnected the battery. It was probably half an hour or so, because I was interrupted. When I reconnected the battery, the Nook popped on and reported a full battery. Apparently it was charging but not registering anything, and the disconnect allowed things to reset.
If you do not any other ideas, I would suggest leaving on the charger overnight (or longer) and trying the disconnect again. Maybe leave it disconnected longer too.

I have the same exact issue right now! But mine is a refurbished unit. I tried the battery unplug, tried leaving it charging overnight, letting it discharge, flashing new roms, new kernels, etc. Nothing. THe only thing that did work a little bit was changing the kernel. Other than that, even flashing stock ODIN roms wasn't working.
When you charge yours, does it charge up to 75% but won't go any further? And does it take an extremely long time to get there? Because mine does. Reading about other devices that have the same issue, it seems to be the battery. But the other devices were phones. This is a tablet. The battery costs $65 :/

I know this is a very late reply and you have probably solved your problem by now, but for future readers with this problem:
I currently have the exact same problem, and just found out what it was. Either my charging cable (official Samsung cable) is faulty. I plugged it into another microUSB cable, and it is now charging again. No more battery symbol that doesn't have the spinning animation or flickering, and now it turns on.

Thanks for this information. Exactly this was the issue. Great!

Charging works and screen stops flickering with Samsung charger if you let it charge in Recovery mode. Mine is still charging as of now, so I don't have any news further yet, but it went from 0% -> 3% after around 30min.
Other than that, I only managed to get charging working with a Motorola's turbo charger.

Nexus 5X doesn't boot - with battery connected

Hello everyone.
I've had this Nexus 5X sitting on my desk for a while. I went to go play with it the other day to see what the hype is with O but unfortunately it wouldn't boot.
Weird thing was, I dismantled the phone to see if there was any internal damage, none. So somehow I tried something, I disconnected the battery and plugged the phone into the mains. Alas, it booted, but not for long. Weirdly enough I was able to get the phone to boot into Android, and then plug the battery in so it could gain some charge. Unfortunately it wouldn't charge, and it would get quite hot.
I thought this may have been a battery issue so I went and purchased a new replacement battery and swapped them out. The same thing happened, it wouldn't boot. Even with the battery plugged in, and leaving the phone plugged into the mains it just wouldn't charge. It's very confusing, does that mean that there is an issue with the battery connector to the motherboard? Or is it a software issue.
If it's a software issue then I can happily just flash a different bootloader and get it sorted that way, but i'm curious to know if anybody else has dealt with this problem before and whether there is a more obvious reason and a fix.
