Slower charge with 2A charger than car charger.

So for the past 2 days my Note 2 has been charging extremely slow with the factory charger. I get maybe a 5-6% charge per hour when plugged in at home but on my way to school this morning, I plugged it into my car charger and it charged 7% in about 25 minutes. Is it my charger or my phone? When I noticed slow charge I rebooted phone and left it over night without opening anything

Well, since I purchased my Note 2, I kept facing this slow charging problem. Now what is slow charging some of you will ask? Well, it's simple. The device is taking more than normal time for charging. Now how do you know the default/should be rate for charging? Simple again. The AC adapter clearly says output rate as 2000 mA or 2.0 A. So with that calculation Note 2's monstrous 3100 mAh should be fully charged with 2 hours. But as we've seen steady 2.0A is not the output case in some/many scenario, so add another 30 mins to it. So whatever it is, from 0-100%, the device shouldn't take more than 2 hours 30 minutes.
And for me, it was taking around 5 hours! Sometimes 4 hours 30 minutes, and if it's very fast then 4 hours. Well I was never gonna wait 4 damn hours before going to my office and irritate myself, and I don't have the habit of charging overnight, unless I absolutely need it.
So I kept calling my retailer, asked for replacement, and they did, well, you won't believe, they replaced three times actually, so I had three different Note 2, with three different charger. Well, each of them acted absolutely fine at first 3-4 charge, then the problem was back again and again. I in fact turned off the device and put it into trash once.
Then I thought let's try some different USB cables, I tried my friend's Galaxy Ace cable. Charging current kept fluctuating between 1000-1200 mA. Which was better than those faulty stock cables, which provided steady 900 mA. Sometimes it even was detecting the AC current as USB, which would provide a mere 460 mA and would take God knows how long! Then I found my piece. I went to my retailer, frustrated and angry, asked them to give me the thickest and shortest possible cable, and they provide me one from a Samsung phone's box, but I can't recall which device was that! And then I sat there for half an hour, kept plugging and unplugging, and the current rate was rock steady at 1800 mA. I took it, paid just 10$ and came back.
Since then I have charged my phone almost 10 times and the current rate never went below 1800 mA / 1.8 A.
This is the cable I am using, do notice that it has 5 pin set up against stock cable's 4 pi, if that matters in any way, and it's about 10% thicker than the stock cable and also about 9" shorter.
And how will you monitor the charging current, three ways are there,
1- Battery Monitor (yet I don't know how to exactly use it)
2- If you are rooted (which is a must anyway), then just go to, /sys/class/power_supply/battery/current_avg
3- Use the app from the link below. It basically reads the current value just exactly as above but it saves the time to go into that file every time. A big thanks to Deadvirus.

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
Sent from my LG-D850 using XDA Premium 4 mobile app

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.

[Q] Slow fast charge?

Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.

yes my phone will go from zero to 100% in an hour no problem when using charger that came with phone

Really? Did it charge like that from the very beginning or did it take a few charges to get to that speed? I think it takes me like 1.5-2 hrs from real low to full charge with fast charge enabled.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?
Has this happened to anyone else with charging issues?

I haven't ran into anything like that yet. Who is your carrier? Maybe you can take in your charger and battery to get it replaced? Can you try charging with a different quick charging phone or something to narrow down if it's the phone or charger's fault?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

Weird, I need like 1.5 hrs to get from 15% to full on fast charge and about 1.75 hrs for 15% to full on slow charge.

i timed my 1st charge. 57 min from 0 to 100. phone turned on and screen off.

Yep, to me that's the best feature. No more battery switching.
I even bought the Verizon vehicle charger with fast charge, and it works just as quick

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.

Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P

I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.

I think I can work around that charging schedule. I am also going to subscribe to that magazine now.

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?

Question Battery charging slow

Hey guys,
hope to get some help here on the forum. I couldnt find any other thread similar to my problem or didnt found it.
So i got the new Pixel 6 Pro and use it out of the box und drained the battery completely. when i wanted to charge the p6p i noticed that it charges really really slow. it took 1 hour to charge 16%. and 2 hours more to 32%. i left the phone charging overnight and noticing in the morning it was at 52% after more then 8 hours of charging.
Im using the original 30w google charger with the original cable from the p6p box. i also tried with my 30w charger from oneplus but didnt work either. i did a soft reset and a hard reset. left it charging with the phone turned off. I tried evertything.
Some of you experiencing the same problem or got any ideas on how to help?
Thanks in adavance.

Try disabling the adaptive charging when you need to top up before bed, this will slow charging rate so you don't overcharge when you have an alarm set that will be coming up within approx 8 hours

i disabled the adaptive charging option and even the intelligent battery option to make sure it charges "normally" but it didnt help.

you need a charger that supports 30W via PD 3 PPS to get fast charging.
OP charger does not suport either and old Pixel charger probbly does not either as this is first for Pixel phones being able to do 30W

i bought the new original 30 watt charger from google (https://store.google.com/de/product/usb_c_30w_charger?hl=de) and i am using the original cable from the p6p box. i just tried the oneplus charger to check if the google pixel 30 watts charger isnt working correctly

Hmm does it say charging rapidly when using the Google charger?

yes it does but it also says 16 hours left of charging
edit: now it says 1,5 hourse left. i will update after this time

now its stuck at 70% and it says full charged in 11 days ...

Have you tried different chargers or cables? Doesn't sound right

Adaptive charging, if you read the description you need to set an alarm to wake up in the morning, and the battery will be at 100% at that time or just before. So I guess if you don't have one set then it will take forever or never fully charge with those settings on.
I am still thinking of taking this stupid google charger back as there is no point having it and I had to buy it, than that over my older google chargers charging over night at a snails pace.
Even during the day when I plug either in they both say rapid charging, and old charger and new one 30W give the exact same full charge time estimation

If you can't measure what is going on, everything is useless. Get a power meter monitor, something like this:
https://www.amazon.com/gp/product/B07D316FHM
I have one for USB A and one for USB C. I literally threw away 3/4 of all my USB cables when I found out they were crap.

Just bought one of theses Anker USB C Charger, 65W .
Max power charging was 13.5W (9Vx1.5A), the same as my Pixel 3XL charger so back it went.
*Edit* After reading the article in Post #18 below it looks like the Phone is the problem and not the Anker charger.

I'm still looking...I miss my OnePlus Warp speed charger!

just to keep you up to date. i got a new one in exchange and it works perfectly ... so must have been a "monday model" (broken battery or something) - i am using the same adapter as before

I just got one of the 30W chargers from Google to give that a go
It charges @18W up from 13.5W on the Pixel 3XL charger, so no real benefit and nowhere near the 30W advertised.

Definitely miss the 65w charge from my Xiaomi which charges in less than an hour!

Tested: The Pixel 6 charges much slower than Google implied
The Google Pixel 6 and Pixel 6 Pro charging is oddly slow despite talk of 30W speeds, taking nearly two hours to fully charge. Here's why.
www.androidauthority.com

for the first time since ive had the phone i let it get to zero and shut down today. Took most of the day to do so, ended up letting netflix play for 5 hours straight and must have been another 3 or 4 hours of tiktok before it died. I wanted to see how long it takes to charge fully. It finally died at 7:21pm and using my pixelbook charger which i think is 45w the p6p said 2 hours exactly to charge to full. Will see if thats accurate or not.
