Charge Cable Issues

I purchased a cheap (.99 cent) USB data cable for my SGS off of eBay from Korea. It worked well, or so I assumed at first, charging my device and working fine with the outlet charge that came in my box as well as working for data transfer.
Originally my first charge of my SGS lasted a poor 12 hours. The second charge lasted a much better time. And the longest mine has ever gone without being plugged in is about 32 hours, this is with low use however. Maybe 5 minutes of talk time total, 100 sms sent and several web pages viewed on WiFi and 3G. This is much much better compared to my 3gs.
Anyways.. After about 4 days of the new cable I had noticed that my charge time was lasting significantly shorter amounts of time every day I used it. Each morning the phone would confirm fully charged and I would unplug it. It would usually end up dieing sometime before I went to bed. Basically it would only last 14 hours and this is with very minimal use. Mostly standby, in fact, probably about 12 hours of those 14 hours is standby.
So I switched back to my original cable that came in the box when I purchased my SGS and today the phone is holding a charge much better and still indicates full charge after 10 hours since I woke up this morning.
I guess what I am trying to say is that it seems (for whatever reason and if you know PLEASE enlighten me) that the after market cable was doing something strange. Even though it charged my device and the SGS indicated it was at 100% please unplug. It still didn't last as long as when I use the original cable. Anybody know why?
So I suggest steering away from cables that may not be official. Or at least the ones that cost less than a dollar XD.

i think the problem is with the battery and not the cable
the cable either works, or don't work, there is no in between.

I was reading a thread last night on XDA about cheap cables but i forget which one. Im sure it was in Galaxy Accessories though.
The guys there were having similar charging issues or it not even recognising the phone being connected. One of them checked the cable on a multimetre and found it was giving a lower voltage than the original (if i remember right it was about 0.2 volts) so maybe that's your cause?
You would think a cable is just a cable but it seems lower costs mean lower quality materials.

i was not talking about the current transfer,
i was talking about the full charge, and drainging quick, has no relation to the cheap cable
yes the cheap cable might be poor at charging the battery, but it doesn't affect how the battery discharges after it's full

He seems to be still using the same battery but has switched the cable and the problem has gone or at least improved.
I remember my old HTC Diamond, charged via USB (lower voltage) would last less than half the time on a supposedly 100% charge. A full charge on the mains socket (higher voltage) would bring the longer holding charge time back.
I guess we need an update from the OP as to whether changing only the cable 'did' fix it.

the point is i don't see any scientific reasonable logic behind it.
AFAIK that's not how the charged power inside a battery works.

Well I have read a bit more about charging from a USB port on the computer than charging from the wall charger.
Many people seem to experience shorter battery life when charging a device (specifically I read about the iPhone cause it was there) connected to a PC via USB. Usable battery time increased when charging via outlet charger.
I am sure there is a scientific explanation for this. Just because we don't know it doesn't mean it doesn't exist. I am interested in this and am going to research it some more.
Perhaps some people should try charging via a PC and USB to see if their battery life diminishes more quickly.

i charge via the PC at work and home for my internal phone battery
the spares are charged separately with a stand alone charger
i see no difference in runtime between wall or PC charged batteries
i'm a heavy user i can drain the entire battery in 4 hours be it wall charged or PC charged
my average battery time when i don't go heavy on it, is 12 hours
on a normal day i need 1 battery pack for AM, and another 1 battery pack for PM

Charging while in use

If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)

I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

Yeah I was charging my phone earlier using a car was adapter with the oem micro usb cable and they phone got very hot.
What do you guys think? Is this a cause for concern? Do I need to buy a manufacturer approved adapter?

Is it safe to leave the phone plugged in overnight? I usually charge the phone when I go to bed, but I've the this might damage some batteries.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..

It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)

I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.

I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:

My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.

[Q] G900P Slow battery charge..fix?

Hey guys. I just purchased the phone and the charging on it is slow as @#@Q. WHen it does fully charge it drains fast, 10 hours with light usage. I have disabled and deleted many apps so far and no go. Right now I am hopeful that disabling google search works. Has anybody else had this issue and have any fixes? My next step is to do a full factory reset, which is no biggy since its new. But would suck to have to download everything again.

Are you using the Samsung OEM charger and cable? If not you will experience slower charging. This is due to the specifications on the adapter + phone itself detecting each other, and applying a special charge voltage.

Of course. Even if I didn't it should never take 5+ hours to charge off of usb 3.0 especially with my pc which has a feature that boosts the amperage for charging. Also a slow charge shouldn't affect its discharge rate.

I fixed the slow charge
Google Search was the problem child. I stopped it and the charging took off. I restarted the app, just because I like it, and it hasnt caused a problem since.
Now for the battery drain, it has only slightly improved. It lasted about 15 hours yesterday with very very light use. Today I let it charge an extra 12 hours and cross my fingers it has only discharged 4 percent with about 30 minutes of talk time and two hours off charger.

What roms camn I flash on the Sprint G900P? On My TMO s4 M919, I was also able to flash the international i9505

How well does adaptive fast charging for you?

Any one actually time how fast their note 4 charges for them? Mine didnt seem to charge any faster than my GS4 the last few days so I finally set a timer, and it charged 50% in just over an hour and a half. Way off what samsung claimed, considering this was supposed to take only 30 minutes...and yes I have fast charging enabled and am using the fast charging adapter.

In 20 minutes charged about 33%. I am happy, cause fast charging working very well. From 25% to 95 % in 60 minutes.

I've done measurements this morning after getting my Note 4 last night.
I agree. I've found little difference between fast charging, and normal at the levels i was measuring.
Perhaps it works faster between 0 and 50%, which seems to be the stats Samsung always quoted. If there is any kind of intelligence circutry going on, it must be varying the amount of ampage being drawn from the charger.
I've found the amps drawn to be VERY low as compared with the S5. Obviously the voltage is the main thing changing with Samsung's "fast Charging" plug.
For example changing from 90% to 100% I found:
USB 2 lead supplied with phone + normal plug = 23mins 31 seconds
USB 2 lead supplied with phone + fast charging plug supplied by Samsung = 23 mins dead.
31 seconds difference is hardly stallar!
Yes you can say it depends on what apps were consuming resource in the background, but it was just standard apps synching etc.
Screen was off the entire time, and nothing processor intensive was actively running.
But I did notice something interesting:
If watts = amps x volts it might explain why the phone isn't charging that fast at the 90% level.
Note 4:
With anker 40w 5-port charge (capable of outpitting 2.4 amps per port, the typical draw was between 300 and 450 ma
With Samsung fast charger it was drawing between 250 and 350ma.
Obviously I'm not counting voltage, which will definitely play a part in the overall wattage. But there has to be some kind of intelligence here controlling it as it's not steady.
S5:
Anker 5-port: 1200ma steady
Fast charger (not compatable of course): 1200ma Steady
Which is also intereting seeing as the max output is 1800ma, so the phone still isnt drawing the max it could do.
Might try draining the Note 4 down even more, and seeing if it does up the draw when the battery is nearing empty

I was very impressed with the charging.
The ultimate test for me was when I was playing a fairly graphics hungry game whilst being connected to the fast charger. It continued to charge the phone up to 100% from 30% in around 40 minutes whilst playing.
I believe the best way to ensure the results are comparable is to make sure the phone is completely powered down and the battery has had a handful of recharge cycles first.
Anyhow, I am impressed with the charging and the battery consumption of my Note 4 to date
.

Impressive. Considering you were using a lot of screen and processing power. Sounds like a wait and see is in order, see how it pans out.
Battery life doesn't seem bad for what I have used, not but much better than I had on the S5. In time I expect things to improve though.

With me fast charging work very well
30 mins then 50% when playing some small game and surfing web

I went from 21% to 75% in about 40 minutes the other day (was monitoring), but my device was on and I had used it a few times in between that time... fast charging is really meant to be used when your device is OFF - that's where you'll get the most benefit.

Mine works fine. Remember it works while screen is off or phone powered down. Also from 0-50 only. Beyond that and it will use 5v to charge instead of the 9v. That's why Fast Charging will only work with the charger it came with.

Are you still having the same issue?
Im charging my phone for the first time and i dont find the fast charging works well with me. Its been an hour already and my battery is still at 30%. I also turn off my phone to make sure i get the 30mins 50% but no luck. Should fast charging kicks in after several recharge cycle?

Remember, it's called adaptive fast charging so it's charging rate varies depending on variables such as temperature, etc.
I went from 20% to 96% in about 60-90 minutes today. Not too bad.
I don't plan on using fast charging much to test, but it's my first few days with the phone and I've been stress testing it to see how battery life is.

90mins for me from 1% to 100%.

no problem at all. been charging from 0 to 100% at exactly 60mins

Impressed with mine used to have a spare battery but not anymore as the beast can really fast.

Must use included charger and CABLE
I found that for fast charging to work you must use the cable and charger that shipped with the Note 4.

hey and im sorry to dig this thread out again, but wondering if another tried fast charging with third party battery, I bought a ravpower note 4 battery off amazon and charged it with my note 4 adapter and I went from 10% to 50% in about 50 minutes, im sure its not fast enough.

note 4 adaptive fast charging
The phone has a chip and the charger has a chip it is this that allows the phone to charge at 9v only between 0 to 50. It's easy for people to be unimpressed because Samsung typically charge quickly. I tried a LG g3 for a few days and it charged ridiculously slow compared to a Samsung if it is taking an hr and a half to charge your phone halfway I would consider using your warranty for a new device or battery

is this correct?
It will only do fast charging below 50%?
What if it starts at 45% - will it stop when it gets to 50%?

I'm finding that Adaptive Fast Charging (AFC) only works (phone reads "fast charging") when the charge cycle is started while the phone's battery is almost dead. Now, "almost dead" means different things to different people, but my GS6 won't use AFC unless it's really low - I know it won't kick on/in circa 35%, but I don't know the precise level.
Here's some an interesting comment made on the awesome article at the link below:
"You should note though, that CABLES DO MATTER. Every el-cheapo ebay cable isn't supported for quick charging. They usually allow about 700mA to pass through. You need high quality cables that probably came with your smartphone in order for quick charging to work. I have done several tests with my Note 4 with several cables and an adapter that meters the output Amperage."
http://www.androidpolice.com/2015/0...-need-to-know-about-charging-your-smartphone/

Works great for me take about an hour and 40 mins from 4-fully charged.

I lost my charger so i cant help here
Been looking all over eBay & Amazon, but nothing...*sigh*

Android 10, problems with slow wireless charge after update?

Hello. I updated my s10+ to android 10 last night, today i was trying to charge it with my wirless charger (slow charge) and once it hit 99% it got stuck... kept saying 3 minutes to go but after 30 minutes was still at 99%.
So I switched to samsung cable charger (with low charge set as well) and in few minutes it got to 100%. So I'm wondering... anyone else experienced something like this? Did android 10 change anything with charge?

Anyone? Tonight i put it to wireless charge again from 70%... went up to 97, then it gets stuck. Says its charging, but even after 30minutes wont go up. With ampere app i can see it says its charging but its barely gettin any ma in.
When I used cable earlier today id get like 600 ma.
Is there really a problem with android 10 and wireless charge?

There's no problem with it. I have 10 on s10+ beta.
Your phone uses more background process and drains it faster than it charges. Use fast charge wireless for a night. You will see yourself it will go up to 100%. Ice used all my galaxy's on fast wireless charge since the s7? Whoever one introduced it. No issues with battery life.

Yes, tried fast charge wireless last night, and it worked to 100%. But the odd thing is that with android 9 i didnt need to use fast wireless to charge it. Also, even now, without fast charge, it does charge itself until 96/97%... it's after that that it wont go higher anymore. If it was just a question of more battery used with android 10, it shouldnt charge with slow charge even between 50 (say) and 97, right? So why does it charge fine until 96/97%? That's what im wondering.

Thank you! Just installed it, ill do some tests next days between fast/slow wireless charge and see whats the difference.
