Does it charge on the wall okay? I would try a different kernel out, see if that remedies it. If not, I would be suspicious of a damaged/faulty USB cable(they do/can go bad), or a faulty battery. Have you tried clearing your battery stats yet? I would do that, as well.

I'm guessing battery too, sprint should have a machine to check it by the way...

It's happened to me a few times. Sometimes the cable wiggles or something I guess.
I just unplug and replug and its fine.

I've had this happen consistently over the past few weeks, only with my car dock though. It charges fine both in my dock at work and on the standard charger at home. I'm using a Seidio dock, and I've done multiple things to find the issue. Both my wife and I have EVO 4g's with Seidio car docks. I swapped my dock for hers, no change. I swapped out the charging cable, no change. I used a different charger, no change. I tried my normal setup on my wife's phone, no change.
I don't know what else to do to figure the issue out. I have ordered a new charger that supplies 2.1A, as I've read that a low charger output could be the issue.
I am confused, as this combination has worked fine for about 8 months now. Why all of a sudden is it no longer charging properly? The battery could be the issue, as I know that the chemistry changes over time, but I'd like to know for certain before swapping out the battery.
I'd love to hear from others who are having the same issue.

Seidio Dock issue?
I've seen a few other posts with the same problem. Particularly this one: Post #1175
http://forum.xda-developers.com/showpost.php?p=16499063&postcount=1175
The one thing that is similar is that he is using the same car dock as I am, the Seidio dock.
I've been playing with this a bit, and have managed to isolate it to the Kernel. I flashed back to MikFroyo and the problem disappeared. It charged perfectly fine.
In Gingerbread (MikG 2.42), with both the stock Kernel and the Freedom Kernel, the phone won't charge properly in the dock. I've been keeping an eye on it with Battery Monitor Widget. Here are the results:

While I am driving, the kernel is showing a 100% full battery, however, it is discharging instead of going into the float mode. As soon as the phone is removed from the dock, it goes from 100% down to 80%. When I put it onto a desk charger, it charges fine with a normal float charge. If I remove the cord from the Seidio dock and plug it into the phone (with a mini -> micro USB adapter), it will charge normally and go into float mode.
Something was changed in the GB Kernel update that affected this behavior. Unfortunately, I'm not a programmer to get that deep to find out where the problem is.
Is there any help possible from anyone???

This always happens to me on AOSP roms. If you happen to be on an AOSP rom, just plug the charger back in then take it out.

I've tried that previously with no luck. I'm using a Sense ROM, currently MikG 2.42, but I had the same issue with the stock GB ROM.
Thanks for the suggestion.

Battery Charging Rate

Hi, I just had my SGSII for couple of days and noticed inconsistent battery charging rate which I've ruled out that is not charger/cable dependent. So I would like to ask if anyone have similar issue or could offer an explanation.
Basically I use the phone charges sometimes at 20%/hour, and sometimes at 40%/hour. I've been using both the samsung stock charger & iphone's 2A charger and there is no correlation between the charging rate & the charger I use. I use debloated Samsung ROM and the faux kernel.
The only other explanation that it could be is that when I get 40% charging rate, I was using 7b4(I think, not entirely sure), at 20%/hour, i was using stock, faux 7r2 or 9r.
below are the screen shot, among 5 times I've charged the phone #2 & #3 were at 40%/hour, the rests were at 20%/hour:

The device will charge the fastest when it is turned off. If you are streaming music, tethering and running other applications, it will obviously charge slower.

My phone has always been on idle when it's being charged so far. what's your charging rate?

Depends on what the phone is doing. If its idle and there are a lot of background processes going on, the rate is slower.

I believe it has to do with chargers in my case.
Since October I've used only two chargers the Samsung one that comes with the phone and my Kindle 1 charger.
Samsung: 40-50%
Kindle: 10-20%
90% of the time the phone is idling.

alright, i charged the phone again using the the stock charger, and it was about 40%/hour on standby mode. Weird I thought I tested it using the OEM charger and it was also 20%/hour. guess I remember it wrong...

ahh.. .here finally found the original topic http://forum.xda-developers.com/showthread.php?t=1332522&highlight=charging
there was a lot of good info on that one, as well as some unexplained behaviour, the same you are trying to figure out
all i know is that yes 2A charger does work, regardless of what the tester shows
and the Battery Widget App, i use it too, and i have to agree it's not very accurate, as it will only show you the actual rater after 2 minutes of charging it
however it's very close to the real values, specially when it's charging and the current flow, i get readings that matches the input quality of the charger, as in USB, Wall, 1 Amp, 2 Amp, 0.7 Amp, 0.45 Amp and so on

there is also the possibility of risking to be stuck at 100% when not using them OEM charger. I have couple of 3rd party charger lying around, so I'm going to try them one by one and see which one works. At least now i know that the apple charger does not work well with the phone(at least the older one, stuck at 100% after charged, and slow charging rate despite it's rated at 1.5Ah+, going to try my newer ipad2 charger).

as for the 100% stuck, as some other have pointed out it only happens when you use AC chargers of any kind
charging via USB doesn't cause the problem
using the original Samsung AC to USB charger also does not cause the problem simply because it's still using USB charging
i had another original OEM Samsung charger that i plugged in and it was also causing the 100% stuck issue, so it's just some sort of confirmation the phone seems to be expecting from a USB power/data cord but is not found on an AC power cord

Battery/ charging issue (constant battery drain) e988

I have been facing constant battery drain for sometime now. Even while charging, battery keeps on draining without much of heavy use.
Plus it may sound weird, but this constant drain is not continuous for days. Some days battery works fine, but some days it just won't charge. For example, last night i kept my phone on charging, but in the morning battery was around 75% charged instead of 100% (charge time was around 7-8 hours)
I am using original charger supplied to me by this phone and the phone itself is unrooted/ stock rom.

Your battery sounds like it sucks.
I am using a method on my phone that shows me (about) how many mA is going in and out of the battery. An App called CoolTool amazingly loaded and complex app, which can do an overlay. I use this app for only One visual overlay, the mA display. (current)
I wont tell you how to set it up, because you will find it. I will tell you it shows how much power is being sucked up, and the reverse shows negative numbers when being charged , at least when being charged faster than it discharges. Set it to update every 30seconds, not a great update rate , but given enough time you can see what is going on. There is another program called "current widget" capable of faster updates, but does not do overlay (cause its a widget), It will work to show power on this here lg too, but i do not find it as usefull, and high update rates could take a bit more battery.
Speaking of charging faster than discharging, turn on the wifi and the screen and mabey some background garbage, then charge it up with either a lightweight wire (to much resistance) or a charger that does not have a good output. And it will use more power than you can put in So when charging on either of these apps that shows current, you eventually want to see actual Negative numbers like -1000 for a fast charge from the OEM charger.
So get a view going , and you can see what is happening. Not all the phones will show this current, and not very many programs do it, And with coolTool we also get to see it (overlay) when gaming, and watching movies. so it is a start to discovery. I have no affiliation with all these programs that i am ending up recommending, other than having been through google store hell for ages trying to find the right ones.

Thank you for the reply. Let me see if it helps
I appreciate your help, but i don't understand a word the app is trying to show me. I am currently using the app, and sometimes the charge goes up to 376mA down to -21mA while doing one time charge.
Is it normal? I don't have a spare charger to try it, but was using OEM charger. Stats i told was from the OEM itself.

So it probably is not your battery, it is probably the rate of charge.
This is a similar quantity that I will see when the "fast charge" is not going , there might even be a notification saying slow charge.
That happened to me 3 different ways.
1) when using a non-oem charger (including pc)
2) when using a different wire, the wires that did not work were either longer or weaker wiring.
3) just because fast charge did not kick in for some reason, disconnecting both sides and reconnecting worked.
I believe that the numbers your seeing , just like what i saw, are a 500mA type Charge rate, it is showing about 300mA (from the battery) when the phone (at least temporarily) is using about 800mA and the negative numbers (-21mA) when it is finnaly using less than the 500mA.
Turning the backlight down (a lot) and turning off ALL the other stuff that uses battery, can get the Use down to about 250mA , or turning it to screen off, where it should use very little.
Still without this fast charge, it isnt going to be a very happy experience, but it is possible to use.

Charger which i use
See the difference in charges and look at the time. (Note each time i took screenshot, i pulled the wall charger out of socket and put it back on. Shouldn't it be constant?)

That is the 1.2A charger, there is also a 1.8A charger.
I do not think that the cool tool has any averaging, it is just a single sample. So it would be all over the place as the use of the phone and charging changes, it will be More the same when the exact same things are done. the exact same screen lighting, the same ammount of cpu use etc for long times. So it can easily vary 500, or under much user control of the phone you can get it to stabalise with +-100 swings.
I have most all of the apps and background data, and Mobile data, and all that stuff under control. You also now have one more app (the cool tool itself) that will be using power. that is why i mentioned controlling it to only 1 thing.
So it is all very normal to see such changes in the sampling, I spent a lot of time getting samples, to get a feel for everything. I dont write them down, but I know what gets it to change now, some things more than others. (some I can do without
You should still be able to shut off most of your apps temporarily and turn off unnessisary I/O and features, lower the light, and wait , and wait to see how the charge is working.

Yep i have already tried and done from past weeks. Some days it just works fine, but other days, it just sucks. I mean looking at your phone with battery going down exponentially in front of your own eyes and you out at office.
But yes, I'll try a 1.8A charger in a few days. will get back to you then

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus X can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Administrators and Moderators!
Please take up the order in the old forums.

Well I don't need sugar+caffeine, but regarding the phone it takes at least 100 minute to charge from 1% to 100% on a power socket. On a USB port - I have not tried yet, but it could take double the time I guess.

Pretty crappy. This thing pulls about 1.2mA from the socket and therefore takes a while to charge up. Say about 2 hours to full from 10-15%.

Max amp draw I get. Same with a 10w USB charger or the one plus stock.

5% to 100% i only need 1 hour 40 minutes something. So its fine with me.

1.5 hours. Pretty fast

Better than Galaxy S3 (my former phone)

120 Minutes (2 Hours) from 5% to 100% for me.

90minutes from 0 to 100℅ which seems pretty fast to me as compared to other phones with "fast charge" which can take take 2h45m for full charge(4000mah)

Hi folks,
Last night, my oneplus X took almost 4 to 5 hours from 0 to 97% (not really 100%!). I noticed this degradation of charging since a couple of months, but i can not figure it out if it came from the battery or from the charger. I tried with another charger, and it takes almost the same time...
And also my battery seems to be less efficient, so i have to consider to replace it or there is another solution ?
Thanks

Well, this is an unfortunate tell of events. Onyx has a very very inaccurate fuelguager and it doesn't seem to adjust with time so as the battery degrades, it gets dramatically worse. I too have the sane issue and no matter what I do to circumvent this in my kernel sources, it always pops back up.
Point being, there really isn't a solution though I do soon hope to take a closer look at the fuelguager and rewrite bits of it in my kernel to improve its accuracy

I had the same issue. At some point charging became very slow. But if it's decharging at a normal rate, then it's not the battery.
In my case, getting the charging port repaired at a local phone repair shop did the trick. Now charging from 0 to 100% doesn't take 4 hours anymore, but again 1.5 to 2 hours.

enable USB fast charging in Kernel aduitor that also helps.
Keep mobile data off when charging that also speeds up charging.

Not sure if the phone is old. It seems slower to charge. 2 to 2.5 hours with no usage during charging.
Anyone face this?
On lineage 15.1 june build and usb fast charge enabled. Using stock charger.

Check charging rate with "Ampere" .
Then, try to unactivate USB debugging and check again (after plug / unplug).

Samsung Note 10.1 2014 Edition (P-601) wont accept new batterys

Hey there,
greetings from germany. Pretty sure this belongs to "Questions and Answers", if not - please hit me and move it.
I am confronted with a, in my opinion, strange problem regarding my P-601 Samsung Note 10.10 2014 Edition.
I will try to provide every action I took and what I figured out so far that noone that wants to help will need his crystal ball. But the first actions are about a year ago, so forgive me if I cant remember exactly.
Device: Samsung Tablet Note 10.1 2014 Edition (P-601)
Problem: Charging slow AF but lives, can be turned on, can be loaded via USB. (But more power is drained while using than can be delivered by charging = dies sooner or later while beeing used)
OS: LineAge OS
First I thought, EASY - get a new battery, done. Wrong.
I ordered a new battery, a (2) "vhbw" battery for "T8220E" - same mentioned on the original Samsung battery.
This is a year ago, In my belief I did get the tablet to run, and charge- but had the same problems regarding the charging speed. Slow AF - but I am not sure! Life happend, things came inbetween so I did put everything aside. Now I want to use it in my home gym, so thats why I came up here.
My next suggestion was that the charge electronic maybe the problem, so I ordered a new one, built it in. Didnt change anything. The (1) Original battery, is still charging slow af.
The new battery, doesnt do anything! If the (2) "vhbw" battery is built in, I am not able to turn the tablet on OR charge it. Its just a brick with this battery.
So what did I do? I ordered a new battery, from a well known german company trading parts like this, a (3) "original samsung battery". Guess what, the tablet does nothing.
So i thought, maybe your new charging electronic is the problem. So I put the (1) Original Tablet battery in again, and well - it runs, can be turned on and can be charged (slow af).
So the charging electronic is fine. Display is also fine.
I did confirm this several times by changing the batterys in and out, the new batterys (2) and (3) are "dead", the (1) original battery runs.
Right now I am stuck. It seems that my Tablet is blocking any battery besides his original one.
Note: I cant access Recovery Mode with battery (2) and (3). Its really dead. They where also charged atleast an half an hour, just in case they were delivered "really dead at 0%", which would be new to me because most devices or batterys come with atleast 25% battery status.
Note2: Yes I did use a ****load of power adapter and cables all in combination, same result.
Any help is really appreciated! Thanks in advance.

Hello, I came here looking for recommendations for a new battery for my SM-P600. Could you tell me where you ordered your OEM one from?
As far as your problem, do you have a multi-meter? There are very cheap basic ones if you don't. Anyway, you can test the seemingly dead batteries with it to determine if they are in fact dead, or something else is going on.
Secondly, do you happen to have a hobby charger? With these, you can charge pretty much any battery L-ion or other. You can also do a drain test with most of these to determine the capacity of a battery. That is all I can really think of thus far. Determine if the batteries are dead. Oh one more thing you could do with the multi-meter is test the current being applied to the battery. I believe there are some free apps in the Google Play Store that can also tell you the electrical current going into the battery. Perhaps by doing this you can determine if the problem is something in the tablet itself. If I think of anything else, I will let you know.
Thanks

Hey,
thanks for the feedback.
You mean battery (3)? I ordered battery (3) from ng-mobile.de
Funny that you say that with the "dead battery", because I just had the same thought 10 Minutes ago. Those batterys were manufactured years ago I guess and were just sitting cozy in their boxes, I guess they are deep discharged. (hope this vocab is correct).
I have pretty much everything that is measured "useless" in a normal household, but sadly no multi-meter (no more). If those batterys are deeply discharged, it should be possible to be reanimated with very low charging power. The lowest I should have is a USB 2.0 Port on my pc (which were it is connected right now) or a oldschool dumb power bank without any intelligence).
I will keep this updated.

solved
It worked. About an hour connected to a USB 2.0 port of my computer, and it just popped back into live. Thanks for sharing your thoughts with me!

There have been reports of the plugs of replacement batteries for these tablets not fitting properly.
Also bad solder joints at the battery connector.
And a certain behaviour i oberved myself, requiring certain custom roms or chargers in case of my P605:
In soft-off state tablet will charge at 0,5A instead of 2A max
and
When powered on it will charge at full power until the screen switches off and it enters standby. Then no charge at all.
