A while back, after sweating profusely into my phone during a workout session, my gnex started behaving badly when I wanted to charge it. Needless to say I've got a battery app installed that is able to detect the plugin state (whether the phone is on battery, whether the charger is plugged in or whether it's just a usb connection such as a computer) and actual % voltage the thing has in the status bar. The app itself is: Battery by MacroPinch.
Well I figured the usb port was probably going so I got a new one of those (i.e. flex cable microusb etc.) for my sch-i515. I also decided to get a new battery just in case... so I replaced the battery (it's an oem samsung one) and fwiw, the thing stabilized its behavior! I've since swapped them back and forth with no apparent issues. However, I took my phone out with me on a run and it started acting flakey again. I've (in the past) had to clean out the port with a toothpick, I've had to on occasion bend the flap in there, do battery pulls (which believe it or not worked for a while), and so on. This time however was different. The phone wouldn't wake when I plugged in or unplugged the charger... and in no way shape or form would the charge indicator come on (you know, lightning bolt in the batter icon etc.) and to make matters even worse this time, my laptop simply didn't recognize the phone was plugged in. So I bit the bullet and and did the surgery and replaced the usb board and mic.
It could not have gone more smoothly, unfortunately (as might have guessed) all is not well... so now:
if the screen is dark -
the phone will wake when the charger is plugged in
the phone will wake when the charger gets unplugged
Using a moto droid cable (from my og droid)
the phone/computer realize they are plugged in together and Wug's NRT works and so on.
BUT the battery STILL won't charge.
I guess the phone is a couple of years old and it doesn't really owe me anything (I guess) but I'd really like this thing working better until I can get a new one. Does anybody out there have any ideas on what I might have missed? The phone works as before, exactly fine except it won't chare so I'm pretty sure I managed to get all the connectors back together properly... I suppose the usb port I replaced the original with might be defective but....
Any help is greatly appreciated...
Oh I'm rooted but stock, android 4.2.2
No advice at all??
I WOULD have said bad usb port, MAYBE try another? They are cheap enough, mine has been broken forever and I do not want to take device apart to change it because crack in my screen I'm worried will get worse if I take device apart.
so since its impossible for me to charge battery in device, I'm NOT worried about THAT tho, BECAUSE a LONG while back I had purchased 2 extra OEM batteries, PLUS a OEM samsung EXTERNAL CHARGER/stand which ALSO came with a battery. so I NOW have 4 total batteries, and I charge them up in the external charger, then just swap them out as needed.
which honestly is GREAT, cuz if I'm going out all day, I can just bring my extra fully charged batteries with me, and not have to worry about battery drain from heavy use cuz I have 3 other fully charged ones WITH me.
that's really all I can say, if you would like help finding the exact external charger that comes with a battery as well let me know, I had bought mine on amazon couple YEARS ago for only like 25-30$ BRAND NEW, I'm guessing TODAY that price would be like ten bucks
Thanks... that may be the way to go but I use this thing for my gps... but the thing doesnt get power when plugged in at all it seems (I plug it in, pull the battery and it does not stay on) so far I've been using my wife's gnex to charge my main and spare... but like I said the thing is, the phone doesn't even stay on when plugged in and I pull the battery (hers does so I'm thinking that there may be something deeper in that's failed here). I cracked the thing back open last weekend to make sure all the connectors were engaged, but I did not find any issues with them past that point.
Does anyone know if there is a hidden connecter somewhere in there that i could possibly have accidentally unhooked that prevents input power from reaching the guts of this thing?
OK it's getting crazier all the time...
Since my gnex was "working" except for charging (also, the phone would not stay powered on with the usb plugged in and the battery removed) I decided to go for a long run yesterday... I take the phone with me for music, tracking and general "safety". About half-way through my run, I look at the window in the neoprene armband I'm using and it looks like a sauna... the bluetooth cuts out on me... so I pull the phone out and with a minimum of fiddling I get the music back on... regarding the charging issue ... I was using my wife's gnex to charge my two oem batteries.
Well after this run, I try and use voice to text in a text message after I got home... well guess what... the phone records NOTHING. It's like I'm not talking. So I try a few phone calls... the display shows the call in progress, but I hear nothing! So I use my land-line to call the phone... NOTHING NOTHING NOTHING.
I had previously replaced the usb port, so I took out the tools and disassembled the phone. there was some moisture in there... anyway I dry it out as best I can and reassemble. Now I plug in the headphones, and guess what... I make calls... i.e. the damn phone works as a phone. I pull the jack out and nothing. I turn on speaker mode ... I can hear the phone ringing when I place a call... turn off speaker nothing. Bluetooth works with the phone fine, and the volume control for multimedia makes no sound when I toggle it...
Fast forward to today. I disassemble it again thinking I might have not reconnected one of the straps... I disconnect the volume rocker connector and the usb port connecter plus I remove and re install the antenna housing.
NOW the phone CHARGES but no lightning bolt indicator in the battery... but the battery level is CLEARLY increasing! Also when I plug into a laptop, the usb debugging symbol comes on (since I have it enabled) but when I unplug it does NOT go away... I unplug, disable usb debugging it goes away... reenable usb debugging and the symbol comes back without the phone plugged in until reboot.... but now the phone WORKS again as a phone!
so now the phone:
charges but without any visual indication (other than the % reporting of the battery widget I use)
phone recognized by my laptop (which wasnt' working either until I reset some of the connectors today), but unplugging doesn't make usb debugging indicator in status bar go away.
Phone speaker and mic now working without having to use bluetooth, plug-in headphones or speaker phone. (mic was not working with speakerphone turned)
This is just too messed up. My sweat does carry a lot of salt.... and Im wondering if I managed to shake something loose... I did also pry the usb tab up a bit as well...
Is there some way... some fluid I can dunk the phone into, which might clean the thing without destroying it?
My galaxy nexus after some drops not charging.
It can only work only when i have connected with my laptop, charger.
I think usb port is ok.
I must buy a charging port to make that work?

I'm not sure if this is the right place to ask this, please excuse my ignorant.
I have an EVO that won't charge. I've read a lot from Google search results that this is a common problem among many users. However, the port seems to be working, because my computer will recognize the phone and storage when I plug it in. The charge led will come on, and the indicator on the phone will say that it's charging, but the phone is actually only discharging while plugged in. Eventually the led will turn itself off, and the phone stops telling me that it's charging when the battery is down to its last drop.
I hope that someone with similar problem can help me with fixing this, or if anyone cause tell me if it's possible to fix? I want to send it in to HTC since I think the phone is under warranty, even if I don't have the protection plan from Sprint? The problem is the touch glass is cracks, and I don't know if they'll fix the USB port without saying that I broke it and won't cover that under the warranty. I want to buy a new screen and replace the broken one, but if I open up the phone it would void the warranty as well...
So I'm stuck with a discharging phone, cracked screen, and having to carry around 3 separate batteries everyday, and I have no idea what step I need to take.
Please help?
Have you tried plugging it into another charger? It may just be the charger that is screwed up. If this behavior pattern is consistent across multiple chargers then you may want to talk to Sprint to see what options you have.

Doubt it's the charger as it was stated that the computer connection works - should get a bit of a charge from that. I agree that a Sprint visit is due.
Just went through this myself! Would plug my phone in before bed and wake up with the phone at 2% or so. Thought it was the battery- so i took my battery to have the sprint store check it, they did say it was bad. So i bought 2 batteries off ebay.
I got the batteries and still had the issue. So then I took my phone to the sprint store and had them check the micro-usb port. They said it was fine and they cleaned it out cause dirt/dust was in it. Still had the problem..
So I bought a new micro-usb cable of monoprice (still using the same wall charger) , and that solved the issue! Had a bad cable. Now my phone charges super quickly in matter of 4hrs.
It could still be the charger. The USB cable sends data and power through different pins. So a bad cable could still transfer data while not pushing a charge.

It's gotta be the port happen to mine and I was able to get it fix as long as the port was still attached to the motherboard, if its not attached then have to go thru the insurance.
EVO with Identity Crisis
I was able to connect to my computer and send data just fine with the old (broken) usb cable.
I've tried three different cable and a car charger, same result; they all say the phone is charging but it only gets discharged. USB/storage connection works. Last time the Sprint store said the battery is faulty, but I have 3 different ones and neither will get charged with the phone plugged in, an external charger will work.

Definitely sounds like a port issue then. If you return to Sprint and review what you've done, as well as the result of your previous trip, then they should be able to take care of you. If they try to tell you it's the battery again just stand your ground. Good luck.
I had a similar issue. I tried everything. It wasn't until I found my HTC cable that it started charging again. I work in IT and tried cables from everything I could get my hands on (blackberries, external drives etc. ) The cable that came with my phone was the only thing that worked.

If you replaced the port yourself, I would love to know how to do it!
Took the phone back to Sprint and they said there's nothing they can do. I don't have the protection plan so I couldn't even pay the $100 to get it replaced (although I probably wouldn't as I can upgrade my contract and get a new phone soon). They also told me that HTC wouldn't cover it under their warranty because the screen is cracked and they will blame that on me for misused. I tried to check the warranty policy on HTC, but the page is not even available. Does anyone have experience dealing with HTC? I bought a replacement screen, I'd like to replace the screen but don't want to open up the phone if there's a chance HTC will fix the USB port...
HTC EVO 4G Won't - Stopped Charging Battery Issue
Hey Guys,
Two nights ago I woke up to an EVO that was plugged in with a Cellet
extractable charging cord, as it is just about every night. But, the phone was
still showing that it was charging the battery, animation with lighting bolt,
at only 50% charged after about 6.5 hours of charging. Hmmm....
The latter after trying to charge in the coffee shop first with Cellet chord in the
wall then a portable 3500mah solar portable charger; the phone not seeming to
charge at or past 50% charged.
My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA
update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The
phone has only been rooted for a few weeks, but I don't see where rooting
would interfere with battery charging.
I've pulled the battery out, several times to no avail. Switched back to the
stock battery, same results. However, if the battery is less than 50% full
the phone will charge the battery to 25% or 50%, weird. If the battery is
at 75% or more full, the phone will top off the charge to a green LED at 100%,
sometimes. Sometimes it won't fully charge the battery. Weird.
I read different posts regarding poor USB chords so I pulled out the stock
micro USB to USB, a charge only chord I figured, and am trying to top
off the Seido battery, which it seems to be doing as it's now full green but
still charging as the animation shows the bolt in the battery and the LED
is still orange.
If put the batteries in the Seido wall charger, the thing the size of a deck
of cards, both batteries fully charge.
I also use Screen Off by Iwashi Soft. That app has worked pretty well with just
a little funkiness now and then. However, while plugged in, I hit the power
button, instead of the home button to turn on the home screen. The phone
wouldn't open to any screen nor would turn on or off. So I ended up
yanking the battery to turn it off then reinstalled battery and turned phone back
on. I don't know if that had any effect on the charging issue, but I took
the icon off the homescreen and am using the power button only, for now.
I don't think both batteries are faulty at the same time at this point. I
don't know if the screen off app caused some wake issue that interferes with
charging the battery.
I do know that when plugging in the phone to charge there's a bit of clunkiness
initially as the phone locks for a second before allowing use for screen or app
and that's always been the case since the gb update. Also, the LED doesn't
always turn green from amber when fully charged with the screen off until
you reboot or use the phone in some way while still plugged in. So there is
some kind of wake issue in the stock ROM. But the latter has never stopped
the battery from charging.
I do know that Plume, the twitter app, started acting clunky with not updating
in the background unless I opened the app at least once after a reboot. But
I don't know if the latter is a wake issue.
Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,
Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the
phone mostly in standby with periodic email and twitter reads, the battery lasts
all day or more than 24 hours. But the latter rarely happens anymore because I'm
a user.
The battery just went full charge with the stock charging cable just now.
This morning, I woke up with a dead phone, auto shutoff even though it was
plugged in which I did after solitaire and before going to sleep; as a charging
test.
I don't know if it's the phone or the Cellet retractable cord or both that's
stopping the battery from fully charging normally and consistently. I'll need
to get another data-charge combo chord and do more testing; and a new ROM.
Any ideas anybody?
try a new rom and also try using the stock charger and usb cable. Check inside your usb port on your phone for dust as well. Also go into recovery and wipe your battery stats. In the wipe menu for amonRa and under advanced (maybe here, i dont use cwm on my phone) in clockworkmod. also wipe your dalvik-cache just to clear any issues you may have, restart and give it a test. good luck
I just bought a phone with a broken charger port. Broke clean off the board, so my next step is to try to get liquid solder and stick it to the board. Did you take ur phone apart to see if the port is lose?
So I used the stock USB charging chord. Sure enough, it charged the phone.
Then I tried the portable charger at the coffee shop, worked. So the Cellet retractable
chord obviously had a short or something damaged/shorted for the charging part of
the cable after a year + of use and abuse.
What I don't understand, and haven't researched, is why there are charge only
chords; the stock USB HTC chord charges the phone, but the PC won't recognize
the phone's Micro SD card or the phone as an external drive. I presume the duo use
chords have a data path as well as a charging path. And yes, I know to switch the
phone from charge only to disk drive. The Cellet chord would provide the PC with
recognition for the phone's drive.
Considering the latter, what I'm not sure of, and haven't researched, is why when
the phone stopped charging, the chord eventually stopped charging, the phone
status still showed it as charging; the amber LED light on and the battery icon
in charging animation with white bolt showing? I presume that the charging path
still triggered the charging status, except once when I turned the screen back
on the battery icon was not animated and the white bolt not showing so I unplugged
the chord then plugged it back in where the battery icon animation continued.
Fortunately, or not, this forum returned 600+ results for 'battery not charging' and after
sifting through a few, the charging chord was mentioned which prevented a Sprint trip
and me contacting Seido; thankfully.
So I think manufacturers and ROM/kernel developers should visit this issue as a chord
that actually is not charging, or charging at an absurdly low rate, should trigger some alert
and not show a battery icon animation that appears to be charging normally.
Recently successfully replaced the LCD screen on my Acer A100. Device worked fine for some time after that repair. Wanting to get a secondary charger for use at work I went to radio shack. Sales "tech" tried several different adapters, found one that fit inside he port, but wiggled. She plugged it in but device wasn't showing a charge. Decided to order one from online. At home the device still would not charge with its own charger. Thought maybe the charger was faulty. Ordered two more. Still the A100 turned off when charger plugged in. Figured tech had burned out the a/c port. Ordered and installed a new one. Still A100 turns off immediately when charger is plugged in. I have 3 chargers now - same results with all 3. Have now ordered a docking station to utilize (hopefully) charging ability through 40 pin connector.
If this connection creates same shut down am I looking at a battery replacement? AM sitting at 33% battery level now, device shut down completely.
Acer wants 199.00 prepaid to submit to them for repair - this is more than I paid for the device! Not really an expense I am willing to pay if all it needs is a battery. There is no erratic behavior , just immediate shutdown as soon as a charger is connected. Any ideas?

If its doing it on 3 chargers its sounding more like a board charging circuit issue. You could remove the battery and then see if it behaves normally, that'll be battery or board right there. Or if you have a multi meter test output at the battery connector.

Don't have a multi meter. Tried connection via new docking station, got same response: device immediately shut off. Tried your suggestion, disconnected battery connected to docking station, got immediate shut off. Same with charger via a/c port. :crying: Mainboard is out? But Device responds and acts normal when in battery mode - or is this isolated to the charging circuit part of the main board?
Thanks for the suggestion!

Sounds like its tripping on the charger circuit and cutting out, like a breaker tripping. IMO look carefully for any shorts on the boards, even something stupid like dog hair can cause strange things to happen. A good blasting with air wouldn't hurt either. It could even be the dock port as it does charge from there and is subject to debris also.

Thanks again for more suggestions. Yup I have been over the board and all connections with a looking glass. Changed out the A/C dock port. My suspicion is that when the Radio Shack tech powered up the "Almost fits" adapter it blew whatever breaker the board has.
When I had it connected to the docking station with the battery disconnected, it powered on, then immediately shut off. So this definitely sounds like a "blown fuse". I completely disassembled and reassembled it again (except for the LCD screen) and checked all connections and plugs. Nothing visible to indicate a burnout or cross connection.
No odd smells either. Probably some teensy weensy transistor or resistor or something. I am not an electrician - just good at R & R.
Another visit to ebay and I am parting with 50 bucks for a "factory refurbished" motherboard. In the mean time, my beloved tablet will await further surgery. Will keep you posted. Board should be here by Saturday. I hope so - battery is down to 27%. Thanks again for weighing in!

To bad considering the crappy battery life so its not like you can charge some other way and swap the battery around.
Example, I have a bricked unit that charges but doesn't otherwise work, so I mean using my bricked board to charge it and the non charge board for use. The a100 isn't really a good setup for swapping around lol. I may actually be interested in that board now that I think about it...

If I could figure out a way to charge the battery OTHER than through the board - I would! Which got me to thinking. One COULD get a second rear panel, cut a door in it, install teensy weensy hinges or create a hinge with cloth tape. then make some sort of extension cord for the battery charging cord, plug it in to the "external" charging board and refill the battery that way.
With a working board and the right know how, one could just extract the board, put it in a box and make a charger out of it too.
But that is just my brain rattling around ideas. :silly: Hopefully this new "refurbished" mother board will do the trick and I will learn my lesson and NEVER let a sales "tech" attempt trial adapters! at 10 minutes to 9pm tonight it was in Texas....
Until I CANNOT use it, I didn't realize how MUCH I used this little tablet!
now it blinks orange?
Oh fer cryin out loud! The motherboard has arrived, I have installed it. Can plug n the charger and drop it onto the docking station and now I get the same response for both charging options: Charge LED lights up orange solid for just about 60 seconds, then begins blinking. Device doesn't respond when power button is pushed UNLESS it is plugged in, and then it just sits at the "ACER" screen.led changes to blue.
OK, wait a minute, this is the third time I have turned it on while plugged in. Acer screen has moved to Android, Device has started. Battery icon showing a question mark. 23%
Turned off, turned back on, now battery shows only 3%????
Think I saw something on the forums about that. will go on a quest.
Finally charging again!
Shhh, don't want to disturb my device....
Found folks on other forums with similar issues of the Acer A100 tablet showing only 3% charge. I removed and inserted the charging pin several times, the device would show solid orange led for about one minute then start blinking. Turned the device on when charger plugged in, unlocked the screen, then with device still plugged in I shut it down completely. Removed charger. Plugged it back in and so far the led is staying at solid orange.
Please keep your fingers crossed for me! This has been quite the roller coaster ride of discovery. Will leave it be for overnight (what is left of the overnight). Then peek at it in the morning. With any luck at all it will have accepted a full charge and I will be greeted with a functioning device! I almost want to learn a new trade..
well now that is weird, got up this morning to a nice blue charge indicator. Yay! Unplugged charger, press on button, hold, hold, hold, hold, hold and device does not start up. Dang it! Plugged it back in, led went solid orange, then started blinking again! Pressed and held on button. Device came on. battery meter shows 3% and a question mark! HUH?
have device plugged in, settings of course show android version 3.2.1 for this motherboard. Guess I need to upgrade it to ICS maybe that will resolve this weird battery issue? Hope soemone here has ideas, feels like I am soooo close to resolving this.
I read the upper posts.
Now I want to share my experience regarding battery load sharing:
I have allso problems to charge the battery.
I have on my tab, for example, 40% of battery power.
I turn my tab off.
When i plugged the charging cable in it shows me the orange led for load.
After two hours or more i turned the tab on.
It shows me not more than 40% but only 37% or so.
So not loaded. This was a bad sign....
I dont no was happend.
I get a little bit nervous but when the tab not get power it doesnt work....
After two/three hours the battery was empty.
Now i can only start my tab while plugged the charging cabel in because the battery will not load.
I have tried several options to find a solution (disconnect the battery, install a new battery, etc. ....).
My solution was fairly straightforward:
I open the tab. Look where the power comes in.
Of the charging socket go four (two red and two black) cable to the motherboard and from the motherboard it goes seven (two red, two black and for me not so important three other coloured cabels) to the battery.
I organized four thin wire and soldered it from the charging socket directly to the battery (of course red to red black to black ).
The result:
When i plugged the charging cabel in while android is running i get no information to load and it shows me not to.
But when i turned the tab off and on again it shows me that it has the battery charged :fingers-crossed: .
After on night while the charger plugged in the battery is fully loaded!!
And of course i get the information in android the discharging of the battery but this is an normaly thing!
So, the problem to load the battery for me is solved .
I hope it helps a little bit for everyone!

I really hope other isn't any voltage or amperage changes needed of that can blow that battery up real quick, plus it can't stop charging, you'll need to monitor that yourself.
Thanks for the info though, it does appear to be yet another somewhat common bug these have that can be addressed by a user if they feel the need to.

Not switch the charger off when the battery is full?
I think the charger there is a shutdown would otherwise overload the battery, right?
Or do this the motherboard?
Anyway, for me the tab is fully working now and if the battery is broken, it is not a big expense to replace them .

I was saying the board is in charge of cutting the battery charge off, not the charger itself so maybe keep an eye on it, its a good way for an explosion or fire.

A100 tablet not charging still
Frischies is much braver than I am.
Wiring the battery direct to the charging port- I would definitely worry about burning up the battery or causing a fire - especially while charging when I sleep. I have had more than my fair share of run ins with fire.
The Motherboard I ordered arrived and I installed it. It was listed as "factory refurbished", but unfortunately will not accept a charge. I thought it had charged overnight at one point, but all it does is blink orange and the battery reads 3% or 0%. Turning the device off when plugged in and doing a reset has not helped. The vendor has been gracious to do a replacement, so I will follow that route until I get a working motherboard.
I have discovered that the docking station will be a welcome addition to my Acer tablet paraphernalia! Although this model docking station isn't the one that allows HDMI throughput, it still will be nice for music, and other media. A Bluetooth keyboard and the tablet will offer yet another computer tool!
First things first though, get the tablet to accept a charge - until then it is a really wide flat paper weight! I am getting VERY adept at opening the tablet and removing the internals!
It is working again! The motherboard sent was defective but vendor issued an RMA. Received the replacement yesterday, installed it last night. Charged over night and fully functional this morning! Ahhh it feels good to have my little buddy back again. Didn't realize how much I used it, until I couldn't use it! Thanks to all for the help.

I purchased an original charging dock and I've noticed some strange issues. There are times when it just seems to disconnect itself randomly. It will charge the phone for a few seconds, then disconnect for a second, then charge for another few seconds and so forth and so on.
There was one time when I placed my phone in the dock before going to sleep, I think the phone had somewhere around 20% battery left and by morning, my phone was completely discharged and it didn't even power on until I charged it by cable for about an hour.
Strangest thing is, it seems to only do this when battery is low. I've tried using it when battery is over 80% and it doesn't seem to show this issue anymore.
Does this make any sense? Should I return it?

I would probably say that the magnetic cable is not connected properly but... If possible, try charging it again, say for a period of time - 10 mins perhaps etc or checked with your friends/family and use their phones to test it out too.
Personally, I never like the dock as similar issues that has happened to you, happen unto me too!
My solution to this - took out the cable straight out of the docking mechanism (do this at your own risk - as it will void either the warranty or refund)
Perhaps this link may gives more information -
I did exactly that. Took out the cable and now it seems to charge ok.

That's great. I had a bigger problem, but not with the dock. My device was not charging(it was discharing) and the phone kept spamming the charge sound. I opened it up and i was suprised that my phone was already opened(bought it 2nd hand) and the dock connector was detached(only the back door pushing it a bit.). I connected it and everything works perfectly now. I am glad that you solved your problem easier.
HI,
had a similar Problem with this docking station. For me it seems that the docking station doesn't fits right to the Smartphone. I put a plastic card (like a credit card, but without any chips) behind the Phone when i charge my phone with the docking station.
So I know all about the problems associated with the Nexus 7's battery draining too far and getting stuck in a type of "deep sleep" that you have to jump through some hoops to get it out of. It happened to me once, and I got it to come back. The other day I'd left it off the charger too long and it died again. This time, nothing I did brought it back. I figured maybe after 4 years, the battery was just officially toast, so I ordered a new one and just finished putting it in. And...
Nothing.
It still won't turn on. No combination of holding buttons down together, or for 10 or 30 seconds makes any difference. No charging indication when I plug it in. Solder points on the USB plug looked fine, and the cord itself charges other things no trouble. Tried a different cord just to be sure even. Just to be on the safe side I even tried a wireless Qi charging pad.
Has anyone else ran into this sleep of death issue? Anything else worth trying on it? It was fine when I put it on the shelf a few days ago, and it hadn't moved since.

The new battery may be as old as your N7 and after years in storage LiPos can completely deteriorate. Please check its voltage measured between pins 1 and 6. If it is below 3V, the battery is useless.
Regardless of battery's condition, let's check if your N7 is OK:
connect it to a PC
press all the 3 buttons for 1 sec
check Windows device manager or Linux lsusb for a new device VID_05C6&PID_9008
The new device appears even if there is no battery connected.
I guess I just took for granted that the batteries were something being made aftermarket, rather than NOS. I'll take it back apart later to check the voltage. FWIW, I left it on the Qi pad overnight thinking that might "trickle charge" it, and the device was warm on back, so it was at least making an effort to do something (assuming the induction itself doesn't cause some heat regardless of whether or not it gets to the battery, which is probably the case).
Anyway, to your steps, I didn't notice it doing anything when hooked to the computer and the buttons pushed. No familiar USB ding, nothing changed in device manager. So, it sounds like that implies something else decided to go wrong. Poor old thing. She lived a good life. She will have a Viking funeral.
I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?
I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.
I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.
Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
