6 reasons why your smartphone battery is charging slowly
The truth is, this problem affects every smartphone after some time regardless of the brand, and usually for the same reasons. In this article, we'll show you why your smartphone charges slowly, and what you can do about it.
Reasons your phone is charging slowly:
- Your cable
- The power source
- Wrong charger/power adapter
- The phone itself is old
- You're using the phone while it's charging
- Background apps are draining your battery
Reason number 1: your cable
The first offender in any case of slow charging should always be your USB cable. I am guilty of this as much as the next person. My USB cable is often filthy and battered! Considering the awful treatment my USB cables undergo, it's no wonder that it is usually why my phone won't charge faster. USB cables get bent, twisted, coiled, run over with chair wheels and generally abused: all of these are not very good for maintaining a solid connection and flow-through of power. Be sure to check the ends too: they can very easily get full of fluff.
Cables aren't immune to physical wear and tear and the USB connector itself also gets worn and can feel loose when you plug in your phone. If the cable that came packaged with your device isn't reliable anymore or you've simply lost it, beware of buying the cheapest charging options online. Higher quality cables have copper wire (some cheapos use aluminum and other substitutes that don't hold up as well) and thicker rubber enamel around the wire, making it more resistant to damage.
Reason number 2: the power source
The next obvious question is where are you getting your power from? If you have a USB cable plugged into your laptop then your phone is going to charge insanely slowly and you'll deserve it. Likewise with Qi wireless charging, which we know from the newest flagships from Samsung, LG, and Google for example. While Qi is a brilliant technology, that brilliance comes at the cost of speed.
Your best bet is to have your phone plugged directly into mains power at the wall socket. However, even this can be problematic, especially if you're in an old building where the wiring might be a little sketchy. If you think this could be the problem, move to another outlet (and then call an electrician).
Reason number 3: the charger/power adapter may not be right
To complete the trifecta, if it's not your power source or your cable, chances are that it's the actual adapter you're using that is causing your battery to charge slowly. There's a reason every manufacturer provides a specific USB adapter for each phone they ship.
Switching adapters between phones can mix-match voltage, wattage, amperage and so on. This is why it's best to stick with the adapter that came with your phone or at the very least take a look at the fine print and replace it with another adapter of the same type.
Reason number 4: your phone is just old
Sorry, but it's true. If you're sitting there wondering why your Galaxy S5 takes so long to charge it's probably because the old-timer is getting worn out after many years of use. Newer processors not only support fast charging, but newer phones even come with turbocharging chargers. Many newer cell phones can get you four hours' worth of usage after just ten minutes plugged in.
Other phones that support fast charging will have a lightning bolt icon on the charger itself, possibly along with turbocharging output figures. Your phone can also become a pocket lint cave too, so check your microUSB port and make sure the little flap in the port isn't bent while you're looking in there. Your battery might just be kaput too, so ask yourself how old it is. At least one advantage of older phones is the removable battery, so if you can pop it out, consider replacing it if it can never seem to charge normally.
At the end of the day, entropy bring a slow but sure end to all things. If your phone is ancient, it's time to accept that it's past its prime.
Reason number 5: it's...you?
It's true - you're the worst thing preventing your phone charging quickly when you can't keep your hands off it. Seriously, if time is of the essence, your best bet is to leave it alone. Mindlessly scrolling through your Insta feed while watching your battery percentage go nowhere is no one's fault but your own.
So leave your phone alone when you charge it, turn your Wi-Fi/data/Bluetooth off or better yet, turn it off entirely. That's actually the absolute best way to charge a phone quickly: turn it off, plug it into a wall with the original charger and take a little break from your digital life (or go to your computer, if you must). Even after as little as 15 minutes.
Reason number 6: background apps are draining your battery
Filled your smartphone with loads of cool apps? That's great, but how many of them are running in the background and draining your battery life? Background apps are a pesky problem on Android, and it can be easy to overlook what is actually happened under the surface on your device. If you have a lot of apps running in the background, they will consume power. This, in turn, will cause your device to charge more slowly. After all, if apps are draining the power as quickly as you are putting it into the battery, it will take forever to reach 100 percent.

unplugging pulling the cable, as many people do,is the best way to ruin the cables
It took 45mins to charging 100% on my S10+ if using Fast Charge powerbank. But 30mins for Wall charger.
It's always helpful to be reminded of what to check cause when things aren't working the way one expects is when we can be blinded to the obvious. When I was having trouble charging my phone I thought the connector on the phone was the culprit. But no, the port had become full of dirt and dark lint which was difficult to see. A thorough cleaning with a needle solved my charging issues. Just my two pfennig.
As long as Trump is president, no smartphone will work optimal!
My phone is charging very slow it was saying it was charging but after 4 hours it still was at the same level. I'll check out what you said. Thank you for the info. P.s. I agree with Dr K.

From 0 - 100 it takes 7 hours on S8+
from 0 to 100 took me 65 minutes on Mi 8.
It's that old proverb: "a watched phone never charges"
A quick temporary fix for android. I attach a strong rubber band to the charger cable, close to the connector, then loop it around the android lengthwise. This prevents the connector from "backing out" and seems to make a better connection.
100% correct
this article made me laugh out loud. and yes, it was the cable for me. XD
Hey Kris. Nice article to help give folks who aren't tech savvy some ideas about why their phone might not be charging as fast as they would like. A a Clinical Psychologist, my impression of the negative and rude comments below suggests a diagnosis of Morosoph.
Certainly there are other more technical challenges that can impede charging but you provided some useful info that I predict many folks found useful.
There appear to be many folks in the world full of bitterness that I hope can find a better way to feel better than to provide derogatory remarks to others.

Glad you wrote that kind comment....... The nastiness online here reminds me of the mobs in days of public executions ... now it emotional pain they happy to inflict . I found the article very helpful. At end of day he gave time to helping others.
Any suggestions for someone who isn't mentally deficient and has basic critical thinking skills? Maybe a better place for me to look would be "how to tell what's causing your phone to charge slow. A guide for the tech savvy, geniuses, and those older then four" detailing how to tell if its the battery or contacts on the phone itself.
But still incorrect
This exactly written the way it was written to make way more sense than the actual actions.. #kindabeenthere
Singularly unhelpful.
i find this article very amusing. why are people even getting butthurt from an article?
I have the same phone as my friend (Reason 4 eliminated), used same power source, charger and cable which he uses (reason 1,2,3 eliminated) and left the phone undisturbed (reason 5 eliminated), still his phone charges quicker than mine. So, actually YOU SUCK for shitting anything on internet.
why does it mean 4 is eliminated? you know devices can be built with errors
My battery stuck at 3% when i use my charger so i bought universal charger then its OK now
This is a joke seriously you guys SUCK
Thanks for wasting my time. These are super obvious sources for this issue. Anyone smart enough to google this issue is smart enough to check if the charger or power source is the culprit. Im trying to use google to find an actual solution and smug cunts like you clog up the search results with your completely redundant articles that do nothing to help.
I am using lenovo vibex2. Since 6 months. Normally it takes 1.5 hrs to fully charged the battery. But now it takes more than 2.5 hrs and it's stucks at some50 percentages. It's battery is non removable and I found a slight bulging at the back cover.. . . PLEASE HELP ME, WHAT IS THE PROBLEM? AND WHAT SHOULD I DO?
Yeah...the bulge is really bad. It means the battery could burst at any given moment. And since you said you can't remove it...yeah get a new one.
Omg it's called humor people! I'm so tired rofpeople being so easily offended! Grow the hell up.
You are offending the public, and I'll have you know my uncle is a lawyer.
Wow this page is (suck) why you r mocking people thing
Don't be so butt hurt. Hes kidding. I found the article amusing.
You weren't even looking for a helpful article, were you. So that's why you find it humorous. It's hard enough trying to recite google-fu incantations for a specific yet hard to pinpoint problem, without having the guffaws in the way.
I have had my Samsung s4 for just over a year and just put a sd card in now it's taken Al day to change and still only 50%charged can anyone help
that means you need to replace your battery
And you won't find a replacement battery that has NFC ability, so you lose that. Unless you buy a second hand one, and then you are just waiting for that one to die too. My original battery will have 50% charge, and suddenly turn off, and when I turn it back on, 0%. The replacement is starting the same now, 2 years later. Cest la vie.
Another (tricky) one: many phones charge slower when using a 2.1A charger port (tablet), as compared to 1A port. This is counter-intuitive, as the 2.1A port should be able to provide an even higher current than the 1A port.
The reason is that many phones does not correctly detect that 2.1A charger ports can provide more than 0.5A (500mA) and would fallback to a safe (slow) charge speed, resulting in very slow charging. The signaling for 1A ports is more simple and most phones will understand it. Actually, most of the phones will not use more than 1A anyway.
Hope this will be considered helpful and ontopic: meaningofstuff.blogspot.com/2015/04/why-my-smartphone-is-changing-very-slow.html
I love how the S6 Edge Charges so fast And the wireless charger made for the S6 phone's is extremely fast.
Even with the wireless charger they made for both S6 phone's they charge faster than any phone I've ever had even if it was turned off
but their right plugging it into the usb charger is faster
My galaxy note 3 front and back camera not working from update to 5.0 lollipop
I feel you're pain my S5 was trashed after the 5.0 update
Especially the camera the auto Focus wouldn't work at all heck I just couldn't get it to focus by any means I did several master resets spent hours on the phone with Samsung and Sprint
Had the Samsung people at Best Buy flash the Software nothing worked
I couldn't type online because it would suddenly move what I was typing back to the beginning of the sentence or the middle and when you tried to delete something you typed it would start adding jumbled letters instead of deleting them until you hit delete a few dozen times
I was so happy that the S6 Edge went on sale when it did so I could rid myself of that update nightmare
install Lineage OS custom rom on your phone that will fix the problem.
Using lineageOS myself. thumbs up from me.
I was really happy with my S5 charging - as Moni Mihailov says in these comments, about 2 hours for a full charge (on mains supply with the original charger, of course). However, I've just gone up from Kitikat to Lollipop 5.0.2 and now the charging time is unbelievably slow. What's gone wrong??
Do a factory reset if you already haven't. It's recommended after flashing a major version of android. That's one of the reasons I'm still on KK :)
Ha. Yes, I'd read that the issue could be related to putting the new Android over old firmware... only I think I updated the firmware barely a month ago. Oh well... better just get on with it, I suppose.
Thanks for your help (and your original comment), much appreciated.
There are some background apps that cause slow charging of the phone...
Galaxy S5 charges for 2 hours from 0 to full. And it lasts at least 12 hours with medium to heavy use and double that time or more with light to medium usage :)
Right on. The S6 really is a breakthrough in terms of battery optimizations, but still, fast charging and power sipping is good, but we still ultimately need better battery tech to take us into the next few years. When UHD screens are the norm we're still going to long for two days' battery life.
True. Enough bumping up the screen resolution. They should start to bump up the battery instead. Full HD is the best screen a phone can and should have. More than that and it's just for showing off and wasting money.
It was one thing to hear it had fast charging but after I actually witnessed my S6 Edge charge charged in the time that my previous phones would only be maybe a quarter of the way
It was impressive
I did however learn one valuable lesson on my previous phone’s I've always turned the brightness completely up except when charging
I tried that on my S6 Edge and the battery went really quick
I found a happy medium though I didn't have to crank the brightness up like I used to and the battery does okay
