Hi all, I have problem with my HDX 7 Unlock BL and Recovery TWRP 3.0.0.
About from ten days up to now, my HDX 7 charge very slow with any charge HTC, Xiaomi, LG (I can not try with original HDX Charge which due to loss it some months ago). I use CM 12.1 dated 10 Jun 16 and also try all CM11 roms. When plug charge to HDX, I check information in Battery section of Setting that has report "charging by USB" but few seconds next change status to "not charging" and again and again.
What is the problem? How can I fix it?
Many thanks any comments.

My kindle charge slow and PC won't detect.
I have the problem that PC can't detect my kindle hdx7. And my tablet charges slowly with wall charger.
This is because one day I charged it with my Quick Charger 2.0. I think that was the reason, and charging circuit has been damaged.
Is it be a real cause?
Does any one has the solution?

Highly doubt the charging circuit is damaged. Nor is it likely a visit with the Quick Charger triggered the anomaly. Far more probable is a problem with the USB cable and/or the USB socket on the HDX. Loose connectors are common especially if care is not taken when plugging/unplugging. Lack of a data connection support this opinion.
Reboot your HDX and try a different USB cable. What is the wall charger rating (should be on the back represented in mAh)? 3rd gen HDX devices can accept charge rates up to 1800 mAH although using a 'stronger' charger won't hurt provided the voltage rating is the industry standard 5V.
Hi
Thanks Davey126

I purchased this tab from a local shop. I tested it on shop, everything was fine.
But when I bring home, and I connected it with my Sony QC 2.0 and I observed charging was slow. I ignored it.
Next day I connect with my pc to copy some movies, but computer didn't respond. I tested my tab with different data cables and on another PC, but no success. Then I did Factory reset, but no difference.
.
I went to shop and got exchange the tab. At shop I tested charging, and PC connectivity. Everything was working fine at there.
I got back home, and again connected with my QC 2.0 charger (until then i did not know the cause). This time I see tab show SLOW charging.
I connected to my PC, same issue, no any detection. Tab only show charging when connected to PC. I repeated all possibilities again to resolve the issue.
At last, I assumed that it was because it may be due to miscommunication between device and charger, and maybe 9V damaged the charging circuit of the Tab.

The Quick Charge standard allows for connection to older devices that do not support QC technology. In that case the charger should limit output to 5V as a significantly higher voltage would likely damage the charging circuit. Either the HDX did not communicate its capabilities properly or the charger cranked up the voltage when it should have remained at 5V.
The maximum charge rate for 3rd gen HDX device is ~9 watts (5V x 1.8A). Yet many vendors target this device for 18W+ QC 2.0 chargers that supposedly reduce charge times by 50% (they won't). Despite the faux claims there does not appear to be widespread complains of device damage. It would appear your Sony 2.0 QC charger may be defective.

Thank you for your concern and collect info about HDX7.
I am a little-known of Quick Charger mechanism. "9V or 12V and 5V". QC 3.0, 4 or 4+. [A Quick Charger does not damage a normal 5V device.]
I charge all my home devices with Sony UHC10 quick charger. I think my charger is working normal as I do not see any abnormal behavior of it.
.
I can not find any other reason to damage my Tab.
Now my question is that, "is there any (alternative) way to resolve slow charging, also PC sync.
Thank you again!

Recommend acquiring a 'standard' 5V wall charger with a 2A minimum rating. This will permit your HDX to charge at the maximum rate (~1.8A) assuming the USB cable is in good shape. Performing this test will help determine if the charging circuit in your device is operating properly.
Most computers/laptops can only deliver a fraction of the maximum charge rate: ~0.5A for USB2 ports; ~0.9A for USB3.

After realizing this problem I am using 2.1A branded charger, but still slow charging.
With Ampere app it shows max 280mA (same as UHC10). It means it is charging at standard rate of 500mA.
Changing the cables does not make any difference. (I have ANKER data cable)
THANKS

Anker cables have a solid reputation. That said, I would double check with another cable.
If cable and charger seem ok then it boils down to termination points (USB connections {should be snug}), imbedded charging circuit and/or kernel. There is nothing you can do about the kernel on a stock HDX. Nor can the charging circuit be repaired short of main/daughter board replacement.
Long shot suggestion: fully power down device and restart after 5-10 seconds. This will insure the bootloader/kernel are fully reset.
BTW - info I provided on QC standards and HDX capabilities are primarily from direct experience backed up by supporting documentation. This isn't just theoretical - I have a handful of HDX devices along with numerous USB meters as charging circuit efficiency (and deficiencies) is something of a personal interest.
@Davey126
Thank you very much
And big thumbs up :good:
I'll try it tonight and then update you as earlier as possible.
@Davey126
I drained my tab battery and then recharge it again but no difference. It woke up after 5 minutes. Still very low rate charging. Ampere app shows 280mAh maximum.
Meanwhile I brought my cousin's (same) tab. With 2.1A it shows +1500mAh on Ampere app. I drained it's battery, and when started charging, it was charging normally. Again in Ampere app @ +1500mAh.
.
I do not want to damage it's charging circuit. So I will not connect it with Sony UHC10.
So it is clear that charging circuit is damaged,in my tab.
If I find any solution, I'll share it here. Till then I'll use it by charging whole night (for 6 hours) everyday. Because it takes 6 to 8 hours to charge 100%.
.
Thank you for your cooperation.

I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.
how can u disable the usb charging? even if its in mass storage mode its keeps on charging.. pls help..
What's wrong with the phone charging?
Isn't it a good thing?
Charge properly
You wouldn’t think that there is a particular technique to plugging your Galaxy S 2 in to charge – and you’d be right. However, you should pay attention to when you charge. If you’re constantly topping up your phone’s battery whenever you get the opportunity, you won’t be doing it any favours.

Constant charging to 100% is actually bad for the battery, if you stop the charging at 90% your battery will live twice as long, with only a 10% drop in runtime.
I had an Motorola defy, and i am sure you could select not to charge the battery, when connected to your computer.
I'm also interested in the initial question...and my reason: if i connect my s2 with the mass-storage capable usb-port of a Samsung TV for viewing photos directly through the Media Player from the TV, i get an error from it saying too much current on usb because of the charging
so - how to avoid this?
A standard tv usb port does not provide enough power to charge the S2, you need a special adaptor that you plug you S2 charger into to provide extra power, see link below.
New Samsung TV`s don't know when, will provide more power to the usb ports so you will not need the charger in the future.

You guys are thinking of NiMh batteries, not Li+ batteries.
Li+ prefers a full charge, does not have a memory effect. If it stays at low power levels 10% it damages the batteries.
Li+ batteries have around 3000 to 5000 deep charge cycle, a deep charge is when you use to around 10% then charge.
It however has more than 2,000,000 micro charge cycles. Meaning you charge it at around 40%~80%
Battery has a cell life span, which means it is going to break regardless how you use it in 2 yrs time.
As for charging via TV, yes, you need a special cable, but that's for HDMI, not USB. The HDMI port is also the USB port on the phone. Standard USB Port supplies 5V 500mA, however, some Computers and Electrical Appliances with a USB port supply different amounts, depending on design.
Computers can supply 5V 1000mA, TVs might supply 5V but less than 500mA. Media Boxes might supply 5V but less than 500mA. Some USB chargers might supply 5V 1000mA but do not have signal in data+ data- lines, which causes the phone to lag while charging.
WIKIPEDIA KNOWS EVERYTHING. Wiki it, it will tell you it is true.. LOL!
so its oki if you plug the s2 to ur pc anytime and charge it anytime?
Pretty much.
I already got an adapter for connection via hdmi, but i forgot and tried to connect as mass-storage. Thought there might be a trick...
I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.

i tried 2Amp chargers....didn't help/

I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.

In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
Using a New Trent External charger I noticed that the phone was still losing power, just at a way slower rate than without it charging. Phone showed charging. I was using netflix via 3g at the time. Would this be expected? Not super worried as the battery charges just fine when screen is off and not in use.
How many amp output is that charger??
My phone can't keep up with the charge if I'm veiwing a movie using HDMI unless I run incredible kernel with fastcharge enabled.
7000mAh. Think 1V output?
IIRC, the stock A/C charger is 1 amp.
A lot of aftermarket chargers do not have the balls to charge the Rezound.
you may need to modify a usb cable to short the Data wires to get the full charging potential out of it.
or try one of these cables from amazon:

Does this cable work for sure with the rezound??
I don't need it right now with the incredicontrol running, but I ordered it just as a handy thing to have.
My new Trent works pretty well, but I wouldn't expect it to keep up with streaming vids. I found that it gives a charge to the idle phone at about 800mA, which is about the same as the stock wall charger.
Pick up battery monitor widget and you can track your plus and minus usage pretty well to decide if everything seems OK.

Well, I'll answer my own question. The cable definitely DOES NOT force higher charging at least when using an HDMI adaptor.
If I use Incredikernel with fast charging enabled with Incredicontrol, it will actually GAIN charge while playing a full length movie through HDMI.
This morning, I flashed back to dsb 1.3 with no frills cpu control & hooked up the new cable for charging. I started with a 100% charged battery & after playing a 1 hour DVD RIP from my card, it was down to 89% charged. Using Incredicontrol, during the exact same test the battery still read 100% at the end.
Thanks for your results jmorton10. Good to know. I wonder if it's the connections inside the HDMI adapter messing with it.
Not sure why HTC can't just get this right to always pull the max possible from whatever it's hooked into!

My understanding is because the MHL adapter needs the USB data pins to work properly and they can't be shorted out as mentioned above, the phone thinks it's on a USB connection and limits it's current draw to 500mA.

That is definitely the problem, the battery monitor widget claims it is charging from USB even though it is plugged directly into an A/C charger.
I guess I will be flashing back to Incredikernel/Incredicontrol tonight. I do like dsb kernel slightly better as it never freezes/bootloops etc. ever on that kernel. It does stop responding occasionally on IC (requiring a battery pull) although it doesn't happen very often.
The Rezound complies with the USB charging specification. If your power source isn't compliant, it won't draw more that 500 mA (and probably less if USB doesn't enumerate, but I haven't checked). That's what the "short the USB data pins" thing is all about. Earlier USB charging spec said they should be shorted, the latest says 200 ohms. Any "USB charger" which doesn't do that isn't compliant, and shouldn't be sold as USB-anything, because it doesn't follow the USB spec. Return it to where you got it, and complain (loudly).
Regardless of how much power a charger can deliver, even if it meets spec you won't see more than about 800 mA go into the battery. There's a limit to how much current both the connector and the battery can safely handle, and the phone takes that into consideration.
Remember, the mA reported by utilities is (always?) what's going in/out of the battery. The charger would be delivering more than that (e.g. 800 mA into the battery, plus 400 mA to power a phone doing video streaming, etc.). AIR, the micro USB connector is limited to ~1500 mA, and I've never seen a battery charge at much more than 800, as reported by the kernel. Conversely, when charging from a non-USB charging spec compliant port, the phone won't draw more than ~500 mA from the port, and the battery only gets what's left after subtracting what's needed to run the phone.
Another thing which can affect charging is the cable. If you have a long USB cable using 28 gauge wire, there will be a significant voltage drop across it. USB specs say the voltage should be between 4.75 and 5.25 V, and Android seems to limit the charging current so the incoming voltage stays above 4.75V. Using 24 gauge USB cables, especially with longer lengths, can increase the charging current. Most vendors don't tell you the wire gauge used in their cables, but Monoprice does (no relation, etc.).
Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?
It seems to do it on any charger or 12volt car to USB adapter capable of outputting 2 to 2.1 amps

Same here. Glad to hear it is not just me. I just got off with NA HTC Tech Support. There official stance is that they do not recommend or support using any device other than the official charging cable and plug in device. They went as far to say that they do not support charging in the car. I just about flipped my lid on the phone.
Here is the link to their site: http://www.htc.com/us/support/howto...783&p_name=droid-dna-by-htc-(verizon-wireless)
"Only the power adapter and USB cable provided in the box must be used to charge the battery"
I was told by Verizon that this was just a scare tactic, while HTC says I am not getting the right charge and they have no answer since they do not support DC charging in the car. Any info people have is appreciated. It works fine with Hard Wired DC -MicroUSB, but not with any USB Plug in.
Any apps that would help me measure the amount of charge it is getting?
Thanks in advance.
What are the specs on your car charger?

So odd that they would do that, especially with the power draw of the phone. However you can charge using the battery packs?
My car adapter is a Macally USB car adapter model carusb10 output 5v/2.1 amp x1 500mA x2.
As for my house adapters the RCA 2 port USB wall adapter. 2.1 Amp x 1 or 1000mA x 2 I believe.

Everyone with a stock DNA unplug your charger and flip it around. As in flip the prongs. It should give you this message even with the HTC supplied one. Or try this. When you use another charger and it gives you that message unplug it and flip it. It should straighten out. I dunno. Something about the way the power is drawn.

I have tried several different USB adaptors, from Razorfish(BestBuy), Belkin single USB input 2.1amp, innocell (RadioShack) dual SUB 3.1amp. Same problem on all.
On the other hand, any direct Wall connection with USB cable attached seems to work fine.
Also, I have the Motorola p4000 battery backup and when I plug that in, it also works fine and views it as AC.
Swapping the pins didn't work for me, same issue. Its a pita for me especially charging in the car because when using phone for navigation it charges so slow that it can't actually charge my phone and my battery decreases. I've went the route in the car I use my nexus 7 charger connected to an inverter.

From my phone conversation with Seth from HTC Support, the slow charging warning is due to the update because the update incorporates the faster charging feature that qualcomm & htc have referenced too recently (can't remember what its actually called). The phone has a new type of charging setup that makes it charge faster than some other phones.
Unfortunately some chargers (wall/car) dont supply enough voltage to activate the charging feature so while the phone does charge fine (it charges at standard phone charge rate) it cannot charge at the faster rate due to the charger.
He states that this will not harm the phone and ther phone will charge fine and it a normal time. You can disregard the warning. For those that like the faster charge rate, you have to use the right charger/cable.
Before the update our phones were mostly charging at the slower rate and that's why most didn't see a warning unless the cable being used was below the standard rate of charge.
Hope this helps

Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?
It seems to do it on any charger or 12volt car to USB adapter capable of outputting 2 to 2.1 amps
Stock ROM, rooted, unlocked, s-off

Why are there so many problems about this thing lately even me, I experience this most of the time
When I use the Best Buy 2.1 amp wall charger I still get the message.
I'll need to find my oem wall charger.
So far every one I have gives this message.
I haven't seen this message at all on any of my charges but I haven't charged in the car yet. My battery usually lasts for more than the while day so I just charge at night.

Well with the faster charging enabled it does charge pretty quick especially using my nexus 7 wall adapter, even with my Nokia Qi pad. But man that last percent takes a while.
As of now I'm using supercharged hatka ROM slim 3.0.3 and getting good battery life. Even in the middle of nowhere where 75% percent of the time when I'm in the plant its searching for signal. I'll leave work after 8 hours and still be at 60%
Guess you can say its the only negative I have for the phone. Trust me the battery life is much better in the plant then my old bionic. I use to have to change the standard battery after 4 or 5 hours as it was completely dead.

Last night I received my daughters replacement Rezound from the warranty company. It came with a 1 amp wall charger.
I plugged it into my DNA and did not get the notice of slower charging and it charged quicker than I've ever seen it.
Too bad my 2.1 best buy one won't.
The quick charge capable chargers must output just slightly higher voltage to trigger the rapid charge mode.
I'll experiment some day and see.
This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

I kinda figured it was something with the pins if I wasn't voltage offset.
I did find that one of my car chargers from best buy runs in quick charge. The cable I fixed, rather than using a usb cable in a slot on the charger.
The best number 2.1 amp wall charger uses a data type cable.
Maybe I'll check into shorting the pins on that sucker to get quick charge mode.

The phone is doing more than checking pins now. I have a 2.1 Amp dual charger with pins shorted and get the warning. It happily charged in AC mode before the update. The charger can also charge a nexus 10 at 2 Amps. I'm guessing the kernel devs will have to locate the source of the warning. I thought the resistance between the data pins might be the trigger, but there is no difference between the HTC charger and my dual charger. It does seem my car charger is unaffected.
I have found that to trick the phone into AC mode you have to short the the actual cable. Hence strip the insulation off the wires and short the data wires together. Has worked for me on all my chargers.

This message does not have to do with the update. I have still not updated my DNA and have been struggling with this for about 6 or 8 months. I am on 2.08. The issue has continually gotten worse since the first time I saw it. At first it would just appear about 1 in 10 times I plugged it in to a car charger. It then got to the point where it would only not show the message with a certain car charger. Now it is showing it on the one car charger that works, but if I mess around with it and unplug and replug it a few times it will finally charge normally. The last few days it has started showing the message on the OEM charger. I have cleaned out the port on the phone and cables quite a few times now, but it doesn't help. I found that doing that only helps if it gets really full of lint and the cable rocks in the port causing it to loose connection if you move it, but it does not change the slow charging message at all. The phone is also definitely not charging at full speed when that message is shown. If I have it plugged in and it shows that message my battery actually drains if the screen is on. With the screen off I only gain about 10% per hour. I am not sure where the issue is, but I think it is different in different circumstances. In my case I think it is the phone itself, but from what I have read about others experiences it seems their problem might be the charger/cord. I hope this gets sorted out soon.

It could be the charging equipment your phone or it could also be the power source not providing enough power to the device for it to charge fast so it charges slow.
