[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

Slow Charging?

I have noticed that my phone charges super slow. A few times, while only surfing the web, my battery % went down while plugged into a wall charger. With the phone off, it would charge about 1% every 2 minutes. Surfing the web this morning for 15 minutes made absolutely no difference in battery %. I started when it reached 63% and 15 minutes later it was still 63%. I am using my old HTC charger, which was super fast with gs3. I dont know what the deal is. Can anyone do some testing? Screen brightness was at 50% while browsing.
Thanks

What's the amperage of the charger? Might not be enough for the G3 and its monster screen. The charger it comes with (based on what I'm seeing online) is 1.8 Amps.

I'd double-check that if I were you. It should be much higher than that otherwise (as you're seeing ) it would take forever to charge the battery. I believe the Optimus G Pro was 2.1 A so I think the 1.8 A I was seeing online sounds about right for the G3.

Ill doble check after work. I ordered a few new charging cables, one is 22awg charge only and the other is 24awg charge/sync. Maybe getting a few extra chargers would be a good idea. Does it matter if i get anything above 1.8A?

First thing to test would be trying the lg oem wall charger with the stock cable that came in the box. if it still doesn't charge properly then I would do a factory reset. I remember this issue when the N5 first came out and a factory reset fixed it

I got so many cables that in not sure which one came with the phone. I did get 2.1A charger just a bit ago.

I'm using the one from my G Pro (2.1A) and haven't had any problems with this phone or my last. Charge times are great and it's got a nice long cable.

The factory one is 1.8A which means it will take less than 2 hours to go from 0 to 100%. This however is dependent on what the phone is being used for during rid time. I've used a 2.0A charger without issue and both work fast. So if my math is correct to go from 0 to 100% will take ~100 minutes, thus 1.8A => ~30mah is charged per minute.
EDIT:
Also I checked on qualcomms website, and the max input rate SD801 SOC can charge at is 2.0A

I have a lot of issues charging with different cables and USB power sources. The stock cable works best on the stock charger, but also charges very fast on my Asus ultrabook with USB3.0 ports designed for charging.
Using basic cables in my car or on various other chargers/power packs, I get HORRID charge times. Do we need to get special cables or what? I bought a 2-amp charger from Sprint, and that cable also works wonderfully. Though for some reason the stock LG cable + 2.1-amp charger in my car can BARELY increase my battery % while driving. I have GPS and data running the whole time.
What concerns me is when I first bought the phone, it would charge just fine on ALL of my cables and power sources. It's like it got more picky over time, and I fear it's from that janky USB connection. The port seems offset, just as many others have reported here.

Have you ever figured out the slow charging issue? This is killing me. I love my G3 but I'm really considering selling it.
My phone is plugged up and it showed 19%, somehow it dropped down to 18%.

I used the OEM LG USB cord with my girlfriend's Galaxy S5 charging brick and it seems to work amazing. I guess the real culprit is the OEM charging brick from LG.

That wasn't the case with me. The original charger was the only one that can charge at 1.8a. All 2.1a that I got weren't even close. I bought 2 more g2 chargers and 3 kopi wires. Now there no issues. I want to try kopi wall charger. So far, their cords and car chargers are the only that actually work well.

I timed mine the other day and it charges a just over 1% per minute so slightly quicker than my Oneplus One and a fair bit quicker than my M8 all using their own chargers that came with the phones.

No. Simple math, 3000 / 1800 = 1.7. So 1.7 hours is the absolute minimal charging time, without any losses, which you will always have.
Also 80 minutes is simply impossible.

Are you using the stock charger and cable? If not, what is the Amperage of the charger you're using? Are you charging from the wall or your computer?

I get a charge from 10% to 100% in around an hour in the UK.

I feel the same about using the phone and charging when playing games. No idea how long it takes to charge it tho, doing it while i sleep anyway.

I'm going to go wireless charging but sometimes I'll turn my phone off and give it quick charge since it charges faster. I know some people don't like to do that though.

the first thing I would check is that the usb cable is plugged all the way into the mains charger. When I first got mine it kept saying usb charging is slow, please plug into a mains charger, which I thought was weird as it was plugged into the mains, but on closer inspection the cable wasn't all the way into the plug, so it was thinking it was using a pc connection. plugged it all the way in and it was charging like a demon then.

Same freaking problem. It discharges 100-0 in 6 or 7 hours, with 1:30 screen on time, and recharges 0-75 in three hours. Have you managed to fix it?

Slow Charging Issues

For the past few days, I've noticed very slow charging on my Pixel even if it says "Charging Rapidly". However it would say it will take around 3 hours to fully charge. When fast charging works, usually clocks at 1 hour and 30 minutes.
I really don't know what can be causing the issue. It's the original charger, and cable. Normally removing the cable and putting it again would fix the issue but it's becoming a common thing for it to take 3 hours.
I remember a similar issue on my Nexus 9 and cleaning the cache would completely fix the issue, but the Pixel XL is missing the Wipe Cache option in the recovery.
Any similar experiences?

On the OEM included charger?

Yup.

Could try a factory reset.. probably the only software related solution. I can't remember, but Chainfire may have said that the cache.img was one of the things that got removed in 7.1 so I don't even know if you could wipe it if you wanted to. You could also hit up Google support... maybe they'll send you a new charger to try. Make sure you're using the OEM cable too, at least for now, until you figure it out.

I had this exact issue with mine, factory reset / charging in safe mode didn't work.
Turned out to be a faulty usb cable but Google insisted on replacing the entire package (handset etc) Replacement works fine

If it makes you feel any better, Google exchange process is amazing.
Raised the return on mine about 4pm and the replacement was on my desk 9am the next morning, they also give you 14 days to send your old one back so you're it without a phone.

I use ampere to see what the charging rate is and I don't feel like the fast charge is that fast.... My 6p charged at a faster rate and my pixel charges at a faster rate using my Choetech smart charger. I'm going to have to drain the battery and see how long it takes to fully charge with the stock charger

Some phones ie lg v10 do not "fast charge" while screen is on (while youre looking at it) to avoid overheating. Ampere cant show max charging rate. I use a usb sleeve (usb doctor) that displays that info or turn on notification display
EDIT: Supposedly Pixel do not fast charge while in use either.

I think I can confirm this. Last night mine showed 27 minutes to charge from about 50% but after keeping the screen awake for about 30 seconds, it went up to 51 minutes.

I also find my Pixel charges very slow as well even though it says Charging Rapidly (OEM charger, cable). The GSM Arena review said they went from 0% to 46% in 30 minutes, I get more like half of that at most. I used Ampere and it said i was only charging at 710 mA.....

If you charge it from almost empty it charges very quick, but slows down once it gets nearer to full

Yes i started charging my phone when it was 4%, and when i looked at it about 20 minutes later it was only at 16%. I think it took about 3 hours to fully charge. The only modification I've made to the phone is unlock the Verizon bootloader and flash the P software (which was subsequently updated to V). I'm seriously wondering if the charger or cable is defective.

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 Moto E4 Plus can charge. A higher rating indicates that it charges extremely fast.

Make sure the charger you received has the output at 2A. I've seen some come with 580mA (I don't know why.). It should be 2A, and charge quickly.

this is the specification found from charger
INPUT:100-240V-50/60Hz 0.3A
output :5.2v---2A
please tell me it is correct specfication if not or not

That's correct. I don't know why it's taking so long to charge for you. It should charge a lot faster. I put mine on the charger at 48%, and it was at 93% an about an hour. Maybe it's a defective charger, or even something wrong with the outlet. Does it happen on all outlets you plug it into?

yes i have tried all outlet but same effect on every outlet!
my friend have the same device it does not have any problem at all. so i thought exchanging charger now i have to wait to until the battery is empty.
hope this will work

Fast charging or quick charging can be affected by either the wall charger or the cord itself. Since the specifications on the wall charger look correct I would suggest try another cord.
A lot of the ones you buy at say a gas station, or a grocery store or just poor crappy cords, and only really meant for charging and not even data throughput, just your "basic" charging cords, meaning no fast charge or anything so it can take forever to charge your phone.
I had this issue where had a Samsung fast charge wall charger, that I use on every phone I get, and yes it does work on every phone I have tried it on, so I know it does fast charge.
What I ran up against was the cord being the problem, I went thru like 2-3 different cords before I found one that worked right, and it took me near a month of frustration and trying things before I finally figured out it was the cord, not the wall charger.

I have the same problem too, my moto E4 plus take more than 4 hours to charge (20%--->100%)
I use too the original charger and cord.

What's up fellas? I just got one of these yesterday and it's having some serious charging issues. In my case, it's not the charger, it's the phone. I think the problem is that I just got it and I'm not leaving it alone while charging. Too much setting up going on and stuff like that. Not to mention, I'm a Real Racing 3 junky. When the phone gets hot it slows down the charging to try and stay cool. My 2 amp charger is working fine, but the charge rate the phone is allowing is only around 300-400mAh when it's hot. I was wondering if one of you guys who's phone is charging very fast could try charging it under stress and see if it slows down like mine does. If yours still charges fast while hot, then I'll know that mine is defective and I'll take it back. One quick and easy way to tell is with the Ampere app. I actually made a little review/tutorial for it on YouTube if you'd care to check it out. Anyway, I'd sure appreciate if one of you could let me know if I need to exchange this one. Thanks a lot guys. By the way, I know it's not the charger because it's putting out 1800mAh when I plug it into my S5. Thanks again.

My e4+ took 2 hours with the 10 watt (AC) fast charger that came in the box with it. I'm using a much slower DC USB 2.0 charger in my vehicle and it normally stays status-quo while charging. I can go a solid 4 days between charging, but I normally re-charge the device while I sleep.

I have been using moto e4 plus from last three months and it usually takes 1.5 to 2 hours to charge 100%.
Hope It helps.:good::good:

My moto e4 plus suddenly stops charging at 80% i put it there for half an hour then I change the outlet,then it charged very fast 80-100 in 20 mins..What is the reason behind this?
