G4 is quickly charging via USB - G4 Q&A, Help & Troubleshooting

I always charge my g4 via usb. My laptop has super charger usb port(MSI Super charger). I suppose, the port gives 1.5 Ampere. My phone is fully charger nearly 1.30 hours. So is that a problem?
Edit: I do not turn off phone and not use it while it was charging. Also g4 charger which comes out the box gives 1.8A so it should charge quick than my usb port. So what is the situation about you? How many hours do you spend your phone?

If you are having charging problems, here are some recommendations I can give to solve the issue.

Lucky you , that myself a avid laptop user, I always wished the phone charged at this 1.5 Ampere instead of the measly 0.5 Ampere (500ma) When screen on it's less than 500 ma wtf! Whether I'm charging via wall charger or USB it just throttles unnecessary. If there was a custom kernel like the amazing Boeffla Kernel (The golden days of Galaxy S3) that should control the charge current even with the screen on. Come on LG u should unlock our bootloaders.

Galaxy S3 <3 I miss those old days still have my very first grey S3 laying somewhere but yeah Boeffla was great for charge control I damaged my official charger and just turned off charging protection and it worked like new [emoji14] also I remember that fast charging on S3, I got 2A official Samsung charger and set that on Boeffla and fully charged in less than an hour [emoji14] I hope that phones as S3 will still be produced. It's no doubt best phone ever made <3

[Q] Battery takes long to charge

I just got a t-mobile version of the S4 and I'm loving it, but I noticed it is very very slow to charge.
Aside from light to medium usage i didn't touch it much between last night and today. I had it plugged in and charging via USB, but it maybe charged about 40-45% in 6+ hours. My old phone (LG G2X) never took this long to charge.
More Info;
This was using the Stock T-mobile Rom
I have since rooted and installed CM10 nightly on the phone, It appears to suffer the same issue
Between 9:27 to 10:00 it went from 67% to %74, My LG went from %39 -%56 in about 20 minutes. By those quick number it will take 7 hours to charge the S4 while only 3 to fully charge the g2x
Is this normal? is there anything i can do to fix/test or alleviate this?

The question for you is the source? If you plugged it into your compy, it will take forever as standard compy USB ports (USB 2.0) provide only about 500 mA. The stock S4 charger is 2 Amps.
The fix, plug the phone into the wall using your stock charger. If it is still slow, it is probably your battery. Good luck.
Make sure to use the charger that it came with. Ever since I started using the stock charger my battery charges fast. Also it could be your plug so test it with another just in case.

Yup it was the charger, I have chargers pretty much where ever i go so i just used those. With the stock one it works great but i ran into another issue. I plugged it in and it was taking a really long time to charge with the stock charger, something like 3% in 30 minutes. I had to unplug and plug in the cable again and it charged normally.
Is this something I should worry about?
It could be possible that the cable was not properly seated in the phone, or the charger end was not properly seated in the wall cube. I wouldn't lose sleep over it unless it happens often. Could be a phone problem, but sounds like a one off to me.
Yea my lady like to use my charger with her HTC phone because it "charges faster". The S4 stock charger has the highest amp rating and provides juice at the highest rate to any device. :good:

There are a few factors here.....
1. The charger itself. The original Samsung is a 2A charger. If you use a different one (most are only 1A) it will take twice as long to charge.
2. The USB Cable. Believe it or not, not all cables are the same. With the standard charger and cable you will be able to charge @ 1900mA. Less then 2 hours to fully charge a completely dead battery. But.... plugging some USB cables into the standard charger will limit the charge down to just 600mA.... taking 3x_ longer to charge.
3. The other is the kernel. If you're using a newer custom kernel Samsung has limited to a max of 1200mA with the screen on & full 1900mA with the screen off.
Lastly, you can download an app on the playstore called Galaxy Charging Current. This will show you the charging rate should you want to test your setup.

This man speaks the truth. I use CurrentWidget and set to manual update. Whenever I'm testing cables/chargers, I plug in a known good cable (charges at 1900) to see what the charger is putting out. I do the same with a known good charger (2A - iPad and S4) and test the cables

How long does it take to charge z1c using usb on laptop?

Hi, it's taking a really long time to charge my z1 compact using the usb port on my laptop (macbook air 2010).
It's been an hour and i'm at 27%.
Is this normal?
Also, is quickcharge 2.0 enabled on our phones? Would it make usb charging from a laptop faster? (I think mine is just 0.5 A, whatever Apple gives you).
Not sure on laptops but on my PC I could charge it for 3 hours to 100%.... While on dock I could charge it like 50minutes and it's full. Quickcharge 2.0 works only on chargers with quickcharge 2.0 support. Hence it won't work on laptops. And it's alot more slower since laptops has lower current output on USB ports than usual outlet chargers.

whhaatt????
i charge using the dock an it fully charged my Z1c at least 3 hours. how can u fully charged yours at 50 minutes only?
I guess it depends on what you plug the dock into. I haven't timed it but I'm pretty sure mine charges from about 40% to 100% in under an hour. I plug the dock into a usb power adapter.
---------- Post added at 09:18 PM ---------- Previous post was at 08:51 PM ----------
Returning to the op's question, if I connect the phone to my macbook pro and then close the lid, the phone stops charging immediately. It charges just fine if I leave the lid open. I only tried it once overnight so I don't know how long it took to fully charge.

Model?
Charger suplied with my z1c is EP880.
About 2hrs20minutes from 5% to full battery.
And i think that is good, charging full battery in 50minutes isnt good for battery health.
Same as yours also... EP880. It says here output is 5.0VDC and 1500mAh. I'm pretty sure the battery is ok as it's holding a 2-3 day lifespan before I can drain it to lower 10%. Although I'm no power user. I mostly use the phone for texting and web surfing... The most battery hog usage I can do is reflashing ROMs in recovery which could deduct 1 to 4% of battery after reboot. Our electricity standards here are 220v of current.

Here's a pic of the charger... Man macro on lowlight rocks on z1 compact
Nice shot Riyal.
Same battery/charger/phone but 250% faster charging?
Thats a riddle for sure, laws of physics says that one of factors in equation must be different.
I suggest you to check yours battery in service centre.
2300mAh (healthy) battery can be charged with stronger charger in 50 minutes, ofcourse that isnt good for her longevity.
But with ours EP850 charger thats impossible, battery or electronics inside phone must be messed up.
Calculating with an output of 500mA from an USB 2.0 port, the charging time (0 -> 100%) will result in approximately 5hours. (Note that the battery is normally never at 0mAh)

Nah no need... I'm pretty sure battery is ok as whenever I charge it on my PC it's charging slow also like any other phones. So I think this is just really qualcomm's quickcharge 2.0 kicking in... Anyways I observed the phone. It's not heating up or whatever probably it's just because of the battery quality. It must be having good chemical reaction when charging hence less waste on energy.

Yours phone is .114 firmware also?
Well, something must be different, my phone and others are charging 2 or more hrs on EP880.
Found something interesting...
I have a energy monitor (http://www.elv.at/elv-energy-master-basic-energiekosten-messgeraet-1.html) between EP880 charger and the wall outlet.
If I use the usb cable EC801 (witch comes with Xperia Z1C) on my dk32 dock, the e-mon. shows about 7.5W energy consumption @~50% battery level !
If I use the usb cable EC450 (witch comes with my Xperia P) on my dk32 dock, the e-mon. shows about 5W energy consumtion @~50% battery level !
Conclusion: Phone charges much more faster with EC801 !
I like the older cable because its much more flexible then the new one - so that's the reason I used the old one and than I saw the differences on the measurement device....
FYI: Charging power is also depended on battery level -
Whats yours charging times (from 5-100%)?
Mine 2hrs-2hrs 20min.
I have EC-801 cable and DK31 dock with hims factory cable, same charging times on both.

Can`t say that for now because I have the phone since a few days....
Edit: Charging time from 20-90%(green led) is 90min. and for the last 10% further 30min.

Yes, thats it, 2hrs is minimum from 5-10% to full battery (with EP880 charger ofcourse).

tab s 10.5 charging extremely slowly

even after replacing battery and charger. Takes 1 hour to charge 1% . this problem started few days ago:crying:any help?
Have you tried an new cable and charger, and check your charging port is clean.
Have you had any flickering on the screen, if so you might have a bad battery connection.
John.
Had the same problem, replaced the battery without success as well. Had to replace the charging port and it's been working perfectly ever since.

yh i to have replaced the battery still no success. yh most likely a faulty port.
This has just started happening to me. Sometimes it gets so bad that it dies on the charger.
I have had my T800 2 years tomorrow and the battery is fine, I use an magnetic microusb adapter so no port wear.
How long have you guy`s had your S1 before you started having problem with the battery? also do you game or use any apps that eat the battery or get the tablet hot as that is really bad for the battery.

i brought my t805 in july 2015. i hardly use it, as i use my nexus 9 which is way faster and easy to carry. i basically didn't use the tab s for a week or 2 and then when i plugged it on charge, it was taking forever to charge, so... :/
i ordered a flex cable from ebay for just £
5, it includes the usb port as well as the sd slot. Will be replacing that, hopefully it will fix the issue.

I wonder if the battery went flat while you were not using it, was it turned off or just in sleep/standby mode.
John.
haha no its not the battery as i have already replaced it with a new battery and still the same. i think it was turned off.
so how long does it take you guys to fully charge your t800/t805 from 0 to 100% while the device is powered off?
From what i have read around 5 hours for the 10.5" for a full charge when in sleep mode, maybe a 4.5 hours when powered off.
But charging speed depends on an compatible charger and quality usb cable, full charge current is 1.75 amps according to my usb power meter on my T800

hmm, because mine takes 3 hours to charge 18%. eventhough am using a note 5 fast charger and also tried it with official tab s charger too no luck.????
the usb ribon arrived yesterday, so replaced it. still no difference.:crying:
Have you tried more than one usb cable, as it make a BIG difference, like 0.5amp vs 1.7amp you can have the best charger in the world but if your cable is faulty or poor quality.
Your battery could be bad (how long have you had your tablet?), or your battery power connector could be loose/faulty(mostly 8.4" S1), or you microusb port could have become faulty.
Also if you use a third-party charger it has to talk to your tablet in an language it understand or you tablet will charge slowly, there are a number of different charger languages Samsung has a different one to Apple, or HTC that is why an Apple charger might only charge your Samsung tablet slowly.
I recommend everybody gets an "usb power meter/monitor" they only cost around $10 and it allows you to see straight away how much power you tablet is taking from you usb charger and some brands can trick you tablet into charging at full speed on an Apple charger, I bought an Belkin 2.4amp charger and it was only charging my T800 at 900ma, I changed a setting on my usb power meter and now my T800 is charging at 1750ma

Hello
After suffering slow charging, like 700 or little more ma Controlled by 3ctoolbox, Im now using a rampow nilon braided micro USB câble.
Now allways charging first at 1750 ma and fall ingénieur slowly from 80% to 100%, like a charging perfect mode must be.
The câble was baught at Amazon and work fine untill now. Verry small prize and quality.

surprisingly i tried charging it with a cheap 3rd party cable and it has charged 48% in 2 hours whilst it was powered off, so it should take just around 4 hours to charge 100%.
when compared to the other 2 official Samsung chargers which charged more like 10% in 2 hours. quite strange results

Your tab will charge at full speed approx 1.75amp from 0% to 80% and then the charge rate will get lower and lower as it get`s closer to 100%
So the first 80% charges the fastest and then last 20% takes a lot longer.
EDIT: 80% of an 7900mah battery is 6320mah So it should take approx 4hrs to charge from 0% to 80% with an 10% charge efficiency
John.

Stock charger very slow

Far from fast charging, the stock charger is painfully slow. I'd let my battery get down to about 20% last night, put it on charge and woke up 6 or 7 hours later and it was at 87%. I put it on an old Sony charger and it was up to 94% in a few minutes.
I noticed that on the stock charger it says "Charging on USB", while on the Sony charger it's "Charging on AC". It's like it's just not seeing the stock charger properly at all.
That's not right. Are you using the original cable too?
The stock charger is a rapid 24w charger.
I know, it makes no sense. Yes, using the original cable. I did try an alternative cable but it made no difference.
The problem seems to be caused by stock charger, use another charger.
Try steps below:
While P2 is still charging at 50% or below (using stock Rapid/Rocket charger and cable), simply restart P2 using Power button > Restart.
Thanks wzedlare, I did that of course, as I said in my original post! However it does not do rapid charge.
Thanks azeemzuhair, I'll try that tonight.
Maybe the ambient temperature is too high? I noticed slower Charing performance when the ambient temperature was too high.

I had the same problem today, I found out that the problem was the screensaver. Disabling it solved the problem
Thanks Uibon, I'd say probably not the temperature, it's winter here so the bedroom is a bit chilly! I hadn't used the phone much before putting it on charge, so I'd be thinking not. Also I switched to the Sony charger and it showed "AC", switched back to the Lenovo charger and it showed "USB".
Thanks Korax94, I don't have a screensaver enabled, so not that.
I tried the power cycle tip, didn't help. I think I'll forget about speed charging and just stick withe the Sony charger, that works well enough!
You do aware that the rapid/rocket charger and cable carries 1 year warranty. Head over to nearest LeMoto Service Centre to claim...
Thanks azeemzuhair, I'm in Australia, it's all via web as far as I can see.
I'll monitor it a bit more and see if I can pin down the issue a bit better before I call them.

Any Wireless Charging Amateurs? Need Your Feedback!

Can someone give me some feedback related to BATTERY LIFE in terms of wired vs wireless charging (fast charging disabled)?
I already know that fast charging CAN reduce battery life. Do we have any info on wireless charging? Since it's an inductive charging, some part of it's energy it's released as heat (not used for charging) and I think it SHOULD affect the battery.
The wireless charger I bought is a Wireless Qi Fast Charge Standing Samsung EP-N5100 with fans incorporated to reduce the heating. (Yeah, I use it on a compatible Samsung smartphone)
I made the mistake to have the fast charge active for some time (didn't know it was active by default), but I only charge it from 40 to 80 so I hope no less damage has been done. Since I plan to keep the phone for a while (I doubt I'll switch in 2 years), I want to try and be careful with the battery.
I've charged my S7 for 2 years almost only wireless (fast charging) and I've had no issues. I keep charging my S9 almost only wireless and I think that for the 2 years (max) I'm keeping a phone, I'll not have any battery related problems.

Thanks. My girlfriend used only fast charging/wireless fast charging and it screwed up her battery life on the S7. Or maybe she let the battery go frok 100 to 0 too many times
Merci pentru raspuns.
Fast charging absolutely wrecked the batteries of HTC 10s, I only use USB-PD now since it's a bit less aggressive than QC3
I'm gonna post something someone told me.
"Just 4u I did a non scientific test tonight using my s9+. Each test ran for 20 minutes. Baseline is phone at rest with all apps closed.
Fast cable charging raised temp 3F.
Fast wireless charging raised temp 15F. (Using 2018 Samsung fast charger)
Slow wireless charging raised temp 11F. (Same charger, not using supplied power supply, forcing slow charging)"
"During my test fast wireless charging didn't get even close to the 113F top limit recommended by Battery University. I wouldn't worry so much. Batteries are finicky, and yours may or may not degrade slowly regardless of the care you take in babying it."
