Sorry if this question has been answered somewhere, I couldn't find it, but I didn't know exactly how to word it.
Anyways, I have a galaxy tab 4, the 7.0 one, and it's charging has been strange lately. I would plug it in when it got to around ten percent, and keep it in. Occasionally it would give me the message to plug in the charger despite it being plugged in, so I thought it might be a faulty charger.
Though after leaving it over night and having it only go up one or two percents, I restarted it, and when it came back on, it had 100% and after that, the battery percentage went down at a normal speed. When using the tablet when it was plugged in and didn't charge, it acted like a tablet normally would when it was going to lose battery (giving me the warning, dimming he screen, etc.).
Do you think this is a charger problem, or a problem with the tablet (or both)?
Note: my tablet has been dropped once onto a hard floor, but nothing happened to it that I've noticed other than the sd card popping out of place, which was easily fixed by just putting it back in and restarting. The charger cord has a few bites on it from forgetting it on the floor with my young dogs, but I noticed them quickly and stopped them, so there's only a few ltitle marks and none of them look deep enough to do much damage (though I've never had samung products before, so I don't know how tough their chargers are).
When in doubt, go ahead and get a new charger. (Keep it away from those dogs too.) If you have the same problem with your tablet, then a call to customer support may be in order.

I've seen a few people with the exact same problem around the web, but no one has ever posted a solution (if they ever found one).
The kids were playing Angry Birds on the Nook before dinner, when I went to turn it back on after dinner it wouldn't boot (was working when I put it down).
When I plug it in the wall charger the light is always green.
When I plug it into a computer USB port it is momentarily detected as omap 3630 instead of Nook Color like it used to, then windows reports that it's been disconnected.
It had been running CM7 for a few weeks off of emmc, but now I can't even get it to boot from a uSD card into CWM.
When plugged in (computer or wall charger) I can see the backlight turn on and off every few seconds.
No combination of button presses seems to have any effect (power, power+n, power+n+vol+, etc.)
Try holding the power button for a full minute... release and try turning it on again... see if that don't do it.
Thanks for your reply.
I wish that worked, but I don't even see the back light flicker on for a split second unless it's plugged into the wall or a computer.
It's a shame too, I got it as a Christmas present from the wife and our toddlers really loved to play the games on it. They keep asking where "bad birdies" went
Your problem sound similar to an issue I had with charging. I has a bad charger/usb cable. Its a known issue and BN will replace it for free. If you are registered, call BN support a request a new one. I have done this twice. Once when the end bent and a second time when I had a green N but not juice (just flicker and/or a 'plug in the charger' symbol). The NC requires more power than the typical usb charger/cable setup, thus spares usb chargers AND cables around the house do not work.
I hate to do this because it was so maddeningly frustrating to see the same thing posted in the thread about boot problems here and elsewhere, but it turned on today and I have no idea why.
I'd been messing with it for a few days and finally after an unsuccessful morning I left it on my dresser. I was in the kitchen making hot chocolate after playing in the snow with the kids when my two year old comes walking down the stairs with the nook and drops it at my feet. When I went to pick it it, it was in the process of booting. Whether he had done something to it or the short fall jarred something that was loose I can't say, but it now seems to be fine.
It had about 50% battery and the lights on the charging cord now respond like they should.
I have no idea what happened, but I wish I did so I could help others in my boat.
Still could be your charger/usb cable. When the charger/cable start going bad, it takes for ever to charge. Like all day just to get enough juice to boot up. If it dies again and doesnt reboot after its been on the charger for a few minutes or you're only getting a partial charge over night, its the charger and or cable.
It charged fine overnight.
There definitely must be something loose on the inside. If I give it a fairly significant whack (nowhere near a punch, but harder than a tap) it will reboot. I think it was a refurbished unit. The newer units seem to have serial numbers where the first four digits correspond to the year. The first four digits of this one are 2004! Looks like they never fixed what was wrong in the first place.
You just ran it too dead. It won't power on until it's established a decent charge first.

So Im a proud owner and enthusiast for the Atrix 4G (original only I cant stand any of the others released they did it best first time around). Ive had this phone with some minor problems for over a year. For a while the phone would randomly reboot in my pocket so long as it wasnt doing anything. If I were playing music on the device it wouldnt reboot but the second I stopped the music, put it in my pocket, and pulled it out it would be powered off. I reset the phone to factory (I had a flashed rooted rom on the device) and the problem stopped.
Now about 3-4 months later I made a phone call put the phone in my pocket to pull it out with a black screen. Now I thought the phone just died was all so I went in and plugged it in to the factory wall charger and to my surprise the LED came on and the phone chirped that it was charging. So it was actually still powered on. I tried looking at the screen from all angles and shined a light on it but there is no picture to be found anywhere. Otherwise the rest of the device (to the best of my knowledge) is still working properly. I could confirm this by my alarm going off in the morning and my in-ability to turn the alarm off due to a black screen.
Also ive pulled the battery, allowed the device to die, and have tried several chargers and other batteries I have so its not a battery or power issue. The screen also remains black on boot, you know the device is powered on once it boots into the OS and chirps that it has service.
Ive dis-assembled the phone to check all the cables in hopes that it would be a simple fix such as a loose cable however everything was double and triple confirmed to be plugged in and locked in place.
I had allowed the phone to die and waited a day or so with the battery pulled out once it had died and then plugged it in and allowed it to charge before powering it on for 30 minutes still to no avail. Ive even tried hard-naving to factory reset and still have had no luck.
I would like to purchase your dead phone for parts.

To me, it sounds like you have a broken LCD screen.
Atrix 4G replacement LCD on ebay
(Note... that is simply the first link I saw on ebay. Do your research before buying anything, I barely even read it.)
Have searched the forum and Google and haven't found anything yet. Usually good at performing obscure random searches but not this time. First off, I am running stock rooted 4.4.4 NI2. Running xposed and wanam but haven't found anything pertaining to my dilemma there either. Onto my issue...
I noticed after I got the phone a couple of months back that it wouldn't be at 100% when I woke up. Usually would be around 97 or so... No big deal. I tested chargers (my wife has/and had an s5 before I purchased mine) and cables with no real difference that I could see. I figured it was some type of protection built into the phone so when it achieved a full charge, it would stop charging until needed. I was perfectly fine with this, but that wasn't the big issue. I have also noticed that if I plug my phone in to charge and end up having to move to another outlet or get into my vehicle, when I plug it in again it won't charge.
The screen will come on acknowledging that it is plugged in, but it will not charge for an extended amount of time. It is almost like the phone has protection built-in so that if there is an issue with a charger/port connecting and disconnecting continuously, it will inhibit the charging until it has a consistent current. I, for instance, am about to head to the gym and wanted to charge my phone before going. It was at 13%, plugged into my nightstand charging. My wife and son got home and are going to take a nap so I unplug and go into the living room to continue charging. It was at 31% and when i plugged it back up a few seconds later it would not charge. I kept it plugged up as i was typing here and it didn't resume charging until is over halfway through writing this post. (5-10 minutes maybe? Haven't tried counting it exactly... Yet) Haven't heard or seen anything like this previously on multiple devices (Samsung, htc, 3 nexus devices, etc.) and haven't been able to find anything online so thought I'd ask here.
Also, sorry if anything isn't stated in a way to describe things perfectly. If anyone has any questions or thoughts, I would truly welcome them.
Thanks in advance.

I recently had my nexus 6p battery replaced. I was told it was replaced with the Huawei brand battery. The capacity seems to be normal again. However, I have noticed that my phone is randomly shutting off about once a week. It will go from using it to just completely blank screen and off. The battery will be at any charge percentage, but when I try to turn on the screen or turn on the phone, it just stays blank. It only works if I plug the phone in, wait for the charging indicator, then I can unplug it and turn on the phone..
I have noticed this has happened when I opened my camera app and when I opened snapchat. I think this is a coincidence, but I am unsure.
I noticed when I plugged the phone in when it had turned off, I noticed a very feint red flash of light below the ear piece. This is supposed to be where the light sensor and proximity sensor are at.
I had it happen again to me when I was opening Android Messages when I was with one of the repair guys that replaced the battery. I used a USB A to C cable to plug it into a computer and then into my phone to show him that plugging it in jump starts it and the battery is not dead. However, this resulted in a bootup, then blank screen. Leaving it plugged in has it bootup and then blank screen and back to off animated charging. Thinking phone was dead dead, I went home and tried to call warranty. In the process, I plugged it into my computer, USB C to USB C and the phone turned on and booted up. My computer has a thunderbolt 3 port. My guess is the power supplied by the USB 2.0 type A port was too low to give it the jumpstart. But when I plug it into the chargers I have at home, which are more powerful, it is enough to jump start it and get it working again. Maybe it is a coincidence about the different charger outputs.
Any thoughts?
I think it might be a battery issue and people were telling me it was part of what's going on in that lawsuit.
Only cheap battery's available for the 6p unless you get a ceno. I purchased a battery from eBay supposed "OEM." The first one did exactly what you first mentioned. Early shut downs and failure to turn on. I didn't even get those with the original battery just that it was getting bit tired. I messaged the seller and he gladly sent me another no questions asked. I've had that battery for 3 months now no battery sensor but works great. I wouldn't hesitate to order another knock off but will make sure it works this time before I put the back cover back on!!! So in other words there's nothing wrong with your phone just that your battery is a lemon. The fact that it's the original battery your having problems with is even worse. If you like the phone spend the $100 and get a shop to replace the battery.

exactly true...:good:
I had the same issue, I tought the new battery was defective or false but it was because android 8.1 developer preview 1. I went back to android 8.0 and the issue dissapeared.
Hope it helps.

This is great to know, thank you. I'm having exactly the same problem as OP. I replaced the battery myself, I have no doubt that the battery is a cheap knock-off version even though it's got the Huawei branding and regulatory info on it.
I'll order another battery and see what happens. Cheers
I got the battery replaced and everything is great. Great battery life and no more restarting and locking up. Definitely was a battery issue.
what's the name of battery please?
Don't buy cheap knock off batteries. Remeber the original battery has a pretty fat ribbon cabble and also has the temperature controller built in the battery here's a pic

I have the same issue as everyone else posting here, except my battery is the original. The battery performance follows normal usage patterns. This means when I charge it, it eventually reaches 100%. When I'm normally using the phone on battery, it slowly discharges. Any phone acts like this.
My problems started when Oreo 8.1 was first installed. Other than being on the beta channel, this phone is not altered, or rooted.
Within fifteen minutes of using the phone heavily while on battery, the phone decides to shut down. The bars at the top and bottom of the screen turn bright red, the screen is greyed out, and it says "Shutting Down" in the middle of the screen. I have not traced this to any particular activity of mine. Usually just reading news or mail. When the phone shuts down, restarting will not work. It gets to the "android" screen, and shuts off again..
When I plug it into the charger The lightning bolt battery shape appears on the screen. Then the filling battery is shown, and it starts filling from very low. The second cycle of the filling battery starts filling from where I expect it to be: in the 80-95% range the phone was at when it crashed. At that point I can restart the phone, while plugged into the charger or not. The battery level indication after the phone is back is exactly what the battery was charged to when the phone crashed: usually 80-95%. I do not think it is a battery problem. I think the battery monitoring software is being interfered with.
Usually I can listen to an audio book with the screen off for a long period of time without triggering the crash. This does not require any network activity. Maybe that's a clue. Also, I have never crashed the phone while it is plugged into the charger. Maybe when the phone is in charging mode, the low battery monitor is not active, so it can't shut down the phone.
I have started putting adb into tcpip mode, and I've captured a few system logs of the phone as it crashed. There is no obvious crash at the end, but there are always a series of strange events, such as permission denials, and processes being killed. I think there may be an out-of-memory condition occurring. There is so much noise in the form of security violations being inserted into the log that it is difficult to determine which error is leading to the crash.
Perhaps I should try going back to Oreo 8.0.

I bought mine on eBay awhile back but don't know if anyone sells the original batteries anymore. You can try though

No, I replaced the battery and that fixed the issue.
2018 may be late in the game to become a new owner of a OnePlus 2 phone. But here I am. My main phone at present remains a Samsung Note 4, and I'm trying to get a feel for how this old (but not as old as the Note 4) phone can be repaired. My issues are a mix of battery, possible circuit board, and other problems / eccentricities.
The phone was given to me non-working. I have a minor-league reputation for rescuing phones, so thought I'd try this one.
First, I had to get it up and going. Nothing worked initially. I wasn't delighted to find out the battery is only accessible after removing two covers and about 30 microscopic screws. I reset it by pulling the small "plug" at top center-right and the phone decided to allow me to boot. I immediately (per instructions I found elsewhere here) went to fastboot and wiped the cache.
I did manage to install TWRP and the latest (as of a few days back) version of Lineage 8.1. But then the problems began again. The phone would suddenly, after charging for a while (and reporting a battery that was nearly charged), shut down. No charging icon showed on the screen.
Fast foward. Today, I got a cheap knock-off battery in the mail. It intially worked and I got it nearly charged. But after more spontaneous reboots I noticed something odd; in TWRP, the battery said only 50% charged while in Lineage it said 97% charged. So once again I wiped the cache and this time the ART/Dalvik cache as well (pointless, but ya never know).
This did get the two percentage reports matching up. And initially it got the phone working again. But alas, once again, the phone started the shutting down.
Currently, I'm leaving it overnight to charge - if in fact it is charging (how does one tell)? If that doesn't work, I'm thinking about using Odin to totally reflash the original version of the operating system.
Any other ideas or input - including laughing at me for bothering with this - is permitted.
I will say that the engineering of this phone compared to the older Note 4 leaves the Note easily the winner; to take its battery out is a matter of 20 seconds. Really not impressed with my OnePlus experience so far...
Thought I'd update things. After spending a day on sites (here and on the official OnePlus community boards) I tried any number of fixes. I'm reasonably convinced the only way to somewhat consistently start my particular OnePlus 2 phone is to:
1. Open it up, thus voiding the warranty (hehehe.... by now that's void anyway).
2. Unplug the battery's small plug at upper right-center of battery (a fingernail works fine, but do make sure the phone isn't plugged in!)
3. *Leave the back off* or at best gingerly snap it on but without attaching the screws. (Every time I did so, even after extensively using the phone while it lay on my sofa's arm and rebooting it numerous successful times previous to replacing the screws, the phone refused to reboot.)
4. I also cleaned the usb c socket with a wood toothpick and was a little surprised at how dirty it was; I did the same in a minimal way to the battery contacts.
5. I found no real use to having the actual OnePlus charger; I used it a bit but my best results came from the Samsung charger and a new (though cheap) usb c cable I nabbed via ebay.
Today I did get the phone going and intentionally wiped Lineage and installed the latest (2017) version of the OnePlus2 official os. It went on fine. I rooted it, installed apps, and (as mentioned) repeatedly shut down and restarted the phone, which promptly restarted with only a 3 second lag. I did this 5 times because one thread I found suggested this was an official OnePlus suggestion. (I rolled my eyes but did it anyway.) Played with the phone a bit, then shut it down again and screwed the back on. As noted, the phone suddenly wouldn't turn on again.
In summary, I'm not sure if this phone can be meaningfully resurrected. If I knew where what may be a short in it was, I could possibly replace that part. But I have little idea and am not quite the geek enough to sort that out. I am guessing at a short because without the lid or screws, it wants to work. It wants to be a good phone for me and I'll keep toying with it for a while longer.
Any suggestions appreciated.
Third post is a question for others:
Has anyone else experienced their OnePlus 2 working fine *without* the back cover screwed on, but as soon as it was screwed on the phone stopped working and wouldn't start again? And, if so, did they ever sort out why?
I'm going to make this a separate discussion.
Hey. I experienced the same symptoms with a "official" replacement battery I found online. Random reboots over and over again until I couldn't even turn it one anymore.
TWRP was always showing different battery percentages than OS.once I put back in my old but original battery that came with the phone it turned on again and it works flawlessly again.

This is something I've read, and may well do. It also, however, raises another thorny set of issues re battery calibration. I understand that sometimes new batteries have to be "calibrated" by being charged, discharged completely, charged again, discharged completely, and charged yet again and discharged. After that, things are supposedly going to run right. Trouble is in my case, the phone doesn't want the battery; it keeps stopping completely and not restarting. Either the battery stats are wholly inaccurate (says around 57% charged during those brief times I've had it up) or I need to go with your idea. Trouble is there the original battery from this phone is dated 2015; I hope it has anything at all left to give.

I'm trying this in desperation. The phone has gone completely unresponsive at this point, and I'm looking at having a technological paper weight. Hope I can resurrect it but the odds are not good.
Some progress, some regress.
Here's what I'm seeing. I can get the phone up and running again after extensive recharging. As long as I leave the back of the phone off - that is, both the inner and outer backs - it seems willing to keep running. As soon as I snap the inner back into place, not even with the screws yet, the phone locks up. Soon after, around 10 to 20 seconds, it shuts off. Sometimes it will restart and other times it won't for a long time, even after unplugging and replugging battery.
Has anyone else run into shorting or grounding issues associated with the back (inner, the one w/ 18 screws) case?
I am now back to a dead phone. A new (3rd party) battery is my current hope... charging it for over a day now has not yet led to the phone showing any sign of life.
One other question: I know both this cable and charger work, but as they are not the "original" OnePlus charger / cable combo, could that be the difference? I'd appreciate it if there is any clear evidence regarding this question.
The below article raises a disturbing possibility, based on the reality that OnePlus cables and chargers are - by OnePlus' own admission - non-standard and possibly could harm other electronics. But on top of that, and not well explored in the article, is whether or not OnePlus' charger/cable combo might even be damaging to the OnePlus 2 (and other OnePlus phones). They "assure us" this is not the case. Hmm.

I thought I'd update this thread with what may be the final installment.
I invested $70 in a highly bent but somehow still working second OnePlus 2 phone off ebay. (The guy had a great fall on a log story as to how the phone got bent.) Long story short... I gambled and won. That is, I gambled that the innards of the second phone would go into my first phone and that the first phone's screen would work. YES. And so, after playing amateur phone repairman, I have myself a OnePlus 2.
So many questions. Going to peruse this board now...
