Extremely slow charging

Has anyone had a problem with extremely slow charging? I would plug my phone in and wake up 6 hours later and the phone is still not charged. It's even worse now with the extended battery. 7 hours worth of charging and I'm only at 85%. I'm rooted and using the de-bloat rom without the kernel, but it was like this even before the root. Has anyone else encountered this strange issue. I have been using the stock HTC charger.

mine charges in a couple hours using the wall charger and wifi hotspot. In the car or via computer USB, it charges very slowly and if wifi hotspot is on, it loses charger over time.

I typically turn my phone off to charge; speeds things up 2-3 fold.

Mine doesn't even take an hour . Power it off and try it that way and see how long it takes.

damn mine charges super fast compared to my nexus s i had

If you have plug to the computer it might take longer but not 6 hours, on the wall it only takes like an hour or two to be fully charge.
If it's an issue just take it back and get another one.

Yeah I might have to return this phone. Do you think it matters whether I use the cable that came with the phone, or a regular usb cable to charge.

You need to look at the power ratings of the adapters you're using. This behemoth phone can receive 1000ma, while many car and home chargers (like Droid1) are only rated at 500ma. I'm still trying to figure out what the power draw is on the phone when just idling (battery monitor widget is hard to understand), but if the phone draws 250-500ma with regular usage, its going to lose charge plugged into USB (rated at 500ma per port) and running hotspot (drawing closer to 600ma). That's -100ma.
These numbers are guesstimates. I'm not sure if the cable itself can pose limitations, but would suspect that as long as there's no shorts in the wire, it would be able to handle any of the above currents.

yeah i find it impossible to charge the thing on USB, and it takes forever plugged into the wall with the charger it came with.
Had an evo, and it would almost full charge (from the time it said to plug it in, so 15%) in about an hour and a half. The thunderbolt seems to take 3 hours ish for me. I know I can turn the phone off, but since it usually charges over night its not a big deal, I just think it is interesting that it is so different.

yeah I'm one of the folks who charges FAST. It has really surprised me...I actually thought everyone was charging super fast until this thread.

+1 on looking at your adapter. Use the one that comes with the phone or make sure that it's rated at 1000mA/1A or more. I tried a MicroUSB adapter I had lying around that came with a bluetooth headset; turns out it only puts out 200mA, so the phone would take forever to charge on it.

with an output of 200mA I would be amazed if you could get this phone to charge at all, without having a custome kernel and underclocking the processor. If anything I would see it maybe staying same battery percentage.

Overall I feel this phone does charge really slow. It is way slow charging on a computer. I was charging it and just doing some light texting and after 4 hours the battery only went up by like 25%.
I have a second wall charger rated at 1000mAH, and after 30min it went up like 10%. This was with the phone off btw. With it on, but not in use, it went up like 4% over 30min. I'm kind of surprised how long it takes to charge. I've had no problems charging it at night. Plug it in before bed, and its full when I wake up. How does the 1400mAH battery size compare to other phones?
I did a little math too, the battery is a 5.18 W/hr battery. So with a 1AH charge at 5V, you'd expect the phone to charge in 2 hrs if only about 50% of the electricity is getting retained by the battery.

I've noticed that mine takes about 1hr 45ish mins to charge from completly dead. My Droid used to be an hour at the most.

i just checked on the adapter it came with, it's 200 mA...did people get better chargers than me or something? Mine takes forever to charge also...been stuck at 99% for 30 mins
EDIT: nvm, i was looking at input, not output...still isnt moving from 99% to 100% though

@lorijuan1024 im with you man the Nexus S took forever...... To charge

its impossible for me to charge it through the computer, it went up 5% over 3 hours, wasnt on hotspot, sending texts.

Mine charges fine on anything, I am using my old fascinate charger.

Charging speed seems to fluctuate for me... sometimes I get lucky and its fast. Other times, not so much.

PowerGen 6000mAh external battery pack

Many times i find myself away from a charger (hiking or fishing) in the middle of nowhere, and I don't know what took me so long to get something like this:
PowerGen PGMPP6000 6000mAh External Battery Pack (w/Imbedded Micro Cable) 1Amp Output- Black
http://www.amazon.com/dp/B008TXCMFQ/ref=cm_sw_r_an_am_ap_am_us?ie=UTF8
There are many kinds, but this one iin particular has a built in micro usb cable (next to the usb port), so no need to carry any extra usb cables. You can charge 2 devices at once also. It compatible with the hox, they actually have pictures of the hox connected to it in the product description, not that it matters but i thought it was cool. And also it was the one battery pack that didn't have any 1* reviews, only 2 or better and now I kniw why. I'm using it for about 2 weeks now. The unit came precharged with about 75% (3 out of 4 leds) and it charged my phone from 25% to 100% in about 2 hours. After that dropped to 2 lights (25-50%). I managed to get another charge, from 40% to 95%, it took about an hour and the charge stayed the same, 2 out of 4. I decided then to recharge the unit with an htc 1A charger (unfortunately it doesn't come with one) for about 4 hours and it was back to full. I used it 3 more times on a full charge and dropped down to low. Bottom line, you can easily use it for three charges, granted I never let my phone discharge completely, I usually recharge when it drops under 15-20%. The unit has automatic shut down after 40 secs of inactivity, although the manual states 20 secs.
It also comes with 2 usb cables and various connectors, of which 2 are micro usbs. It also has a built in led flash light good for 270 hours of use on a full charge, but I don't really use it.
If anyone interested, i really recommend this because of its capacity (6000mAh) perfect for its size. Is not big at all.

How does this compare to the ankers?

Thanks for the review. Quick question... after using this thing for a while, have you noticed it's charging process slow down at all? I had a similar unit that didn't charge as fast after a few months of use.

I need one...

Not really, didn't notice any substantial difference, but again I only use it once a week (weekends actually while out) and since I only have for about 3 months it's still new. Oddly though it seems to me the charging time increases if I use the USB cable as opposed to the built in one, but I didn't really timed anything it's more as a feeling.

Charging slow???

Out of the blue I noticed my S3 was charging very slowly, it even was losing a charge while it was plugged in while I was using it. I figure it had something to do with my custom ROM so I reflash, still same outcome. The battery was still holding a good charge, so I figured it was something else. I then went out and bought a new charger, which came with a micro usb cord to see if that helped. Plugged in the new charger while using my old micro usb cord, still same outcome. Then used the new micro usb cord and old charger, charging went back to normal, problem solved! I would of never thought that the cord would malfunction from day to day use after such a short lifespan. Moral of the story, check your cords if you experience the same problem, it could save you some time and money!

I bought some cheap ones off Amazon. They won't charge the s3 but will my touchpad. But my s3 charger won't charge my touchpad. Stuff is weird at times.
Glad it was an easy fix.

Must have been charging in USB mode.

I believe it, using my old galaxy nexus cord for my s3 charges extremely slow (like 200 mAh) for some reason. I switched to a different cord and now it's all good, I have no clue why but that's how it is.

That's weird mine started doing the same thing just in the past few days. I have to unplug and plug it back in multiple times before it goes into AC mode

I really think that those cheap cables don't charge nearly as fast. Especially the Stock Sammy ones. I use the thicker LG cables and they seem to charge so much fast and transfer files faster..

I just went through the same thing. The phone was charging for twelve hours and only gained 50 percent. Took forever to figure out it was the cord.

USB Cable
I think charging AC is not fast charge.
You should to charge USB cable.
Thanks.

That's what my phone was doing, I'd unplug then plug it back in and would go from USB to AC, but it still charged slow. That cable, no matter what it said, would still charge slow as balls.

I had heard of "Buy Cheap, Buy Twice", but now we've got "Buy Cheap, Charge Twice"

A lot of times it's the DC power brick that makes the difference. Not all of them have the same power output. Rarely, if ever, is it the actual cord itself. USB cables use pretty thin gauge wire already and the only way you're going to get a difference from one cable to another would be if it was REALLY cheap and using an ultra-thin wire or if it was a REALLY long cable (increases in cable length equate to increased resistance to electrical transmission...)
All USB cables are 5 volts. However, there can be significant differences in the milliamp output for each DC adapter. Aside from being a computer geek and gamer who builds custom PC's, I happen to be a hotel General Manager. I just checked our catch-all box of phone chargers and found that while every charger has an output of 5v, the amperage put out varied from 350 mA to 1000 mA from one charger to the next.
This variance in output is why some chargers take so long as compared to others. I don't know what the actual Samsung charger output is, since my charger is at home, but my guess is it's between 800 and 1000 mA.

I use the stock BB charger to charge both my 9900 and GS3, the BB charges pretty normal but lately I've been having a problem with the charging time on my S3, I have to charge it everyday now, my usage isn't that heavy, it lasts me a day and a half normally. Going to start using the stock charger to see if there is a difference.

I'm using the Samsung stock charger after not having used it for a month and noticing that my battery levels have deteriorated after using my BB stock charger. The battery seems to be discharging while on the charger! I'm in for a world of pain, going to monitor it for a while. I could be stressing over nothing.

[Q] Forever to charge...

Hopefully I don't get flamed for this as I have been doing searches but so far nothing...
I got my HTC OneXL and that night I flashed Viper onto it. I don't know if it's the ROM or the phone itself, but it takes a really long time to charge. I plugged it in 2 hrs ago at 50% and I'm only now at 60%.
Battery life is hard to know length as I've had the phone a week and have been customizing and setting it up etc.
Is the charging a known issue to the phone or is it the ROM? I'm coming from the Iphone 4S and that thing charged up really fast.
Any help is greatly appreciated!!

Charging it from the pc or from the wall? Using the cable and power adapter it came with?
10 percent in 2 hours is slow. Typically in 2 hours I'll get about 50 percent or more.
If you have a 30 day faulty return policy I would take advantage and make sure they replace the power adapter too. Typically they would of course but I thought I'd specify just in case they wouldn't want to for whatever reason.
If you don't have a return policy available, I would try another usb power adapter for a couple hours as that would be my first guess as the culprit for this though it could also be an issue within the phone.

I had the phone given to me and it didn't come with the original cord. I'm using the cord from my Xoom so that could be it...
Sometimes I use the wall charger, sometimes my pc and sometimes the USB port in my car. Guess I'll have to try and track down the actual cord and see if that works. It'd be cool if those dots on the back had an actual charger that worked for them!

Charging from a PC is slow, and from a car is extremely slow. If the 10% in 2 hours is from car charging, it would not surprise me, and pretty normal.
MicroUSB chargers or cords from most phones will work just fine on the this device, but don't know about the Xoom. I suspect either the charge source (car, PC) or cord may be the issue here.
Also keep in mind, that after a ROM flash, the battery meter is not completely accurate. You have to do a charge cycle to full, then drain to 10-20% for the high/low "flags" to be properly set. This might be part of the issue. But I haven't seen it cause such a slow increase in readings while charging, so I don't think its your main problem.

Battery Drains Faster Than Charges

My battery seems to drain faster than it charges. I bought the phone off of craigslist and it did not come with the original charger and cable. I did have a nexus 4 and its original charger. I use the Nexus 4 charger, which is rated at the same 1.2a. Is it the charger or is there something wrong with my phone? I read a lot about slow charging and ppl searching for the right charger. I just want to be able to use the phone at night with a low battery and plugged in. Otherwise the battery does last a long time and seems healthy. I am able to go the whole day without a charge but i then cannot use it while I am home. Any advice is appreciated. I could prob RMA it if needed.

Just do a fresh install using Google's own images and see if it fixes the issue

This is a fresh install. I originally received the phone with Android L Preview. It was buggy and there was an unknown service consuming a large amount of battery power. I did a fresh install of 4.4 from Google.

I had the same issue with the stock nexus 5 charger. Turned out something went wrong and it wasn't providing enough current about 250mAh. I switched charger to a higher one and everything works as it should, charges in about 1.5hours. I suggest you download GSam App that shows the current while charging.

In settings/battery, when the device is charging, does it show USB or AC charging?
If USB charging, get a different charger and/or cable.

I got that app and I'm a little unclear on the readings. I see a positive number and a negative number. I got a -623 on the charger I have been using at work which is for a dell venue and I believe 2 or 2.1a. That one does seem to charge the phone OK. I'm at home now on my nexus charger and I have 431. I have a 131 not plugged in.
It says ac not usb

I started to read that but my issue is really with charging. My battery lasts a long time. I can go all day without a charge but then by the night it's in the teens. This normally would be OK but that plugging it in doesn't stop the drain. I do a lot on my phone before going to sleep, laying in bed. Now I can't because the phone just dies even while plugged in. I ordered the blackberry playbook chargers mentioned in another post. Ill have to see when the come in.

use a toothpick and clean the contacts on the usb, look for any lint and such... sometimes a bad connection may not let it charge properly.

Just use another charger, or cable and check the mA readings. - 1000, give or take, is good. Much less and it's the cable or charger.
Gsam can show you the value in the main screen... And it's a great app in general. ?
