People don't try cleaning their charging port before buying a new device? Thats crazy. I really have a hard time believing people don't try cleaning before buying a new device.

[–] fuckwit_mcbumcrumble@lemmy.dbzer0.com 51 points 6 days ago (2 children)

Some people are just absurdly lazy.

Also what kind of kit does op have? A sim card ejector, a metal brush, a q tip thing, half a zip tie, and some adhesive things? Any thin plastic shim will work perfectly, and sometimes even a stiff plastic bristle brush works well.

[–] slazer2au@lemmy.world 50 points 6 days ago (3 children)

Not all are lazy, some just don't know.

My in-laws didn't clean the dust out of their PC for almost a decade because when they purchased it, no one told them to clean the filter on the front.

Most people buy a new cell phone long before the charger stops working.

I'm weird. I've had my cell phone since 2020. But MOST people buy one every 2-3 years. Just because the newest latest and greatest just came out.

My 5 year old phone still has no issue charging. And when the battery starts dying, MY battery is user replaceable.

I mean, it's one phone, paper_moon. What could it cost? $1000?

[–] BroBot9000@lemmy.world 12 points 6 days ago

I’d believe it, especially with all the propaganda from big corporations and the fomo they push with new technology. Looking at Apple and their fucking yearly phone cycles.

Don’t forget to consume more! Buy two just in case! Consume! CONSUME!!!!!!

A 1¢ toothpick works 99% of the time.

[–] b_tr3e@feddit.org 32 points 6 days ago

For the missing 1% use isopropanol.

Alternatively, just grab a free toothpick from a restaurant and use that to clean the port.

[–] starman2112@lemmy.world 6 points 5 days ago (2 children)

Toothpicks are WAY too thick. A sewing needle did the job for me though

[–] Artoink@lemmy.world 6 points 4 days ago

I wouldn't use metal to clean it. A sewing needle is surely hard enough to scratch the coating on the pins. Plastic or wood would be less destructive for repeated use.

The old Reddit trope

The real LPT is in the comments

[–] YiddishMcSquidish@lemmy.today 4 points 5 days ago (1 children)

Kinda, you really want to use a soft brush and 90% isopropyl. A tooth pick is only useful if you are EXTREMELY gentle. Otherwise you might cause more damage.

No need to waste money on a "kit" for such a basic task.

[–] FireWire400@lemmy.world 7 points 5 days ago (8 children)

Yeah, a toothpick or even a toothbrush will do the trick if you're careful. And without creating unnecessary waste.

And if that doesn't work, take it to a shop to replace the port.

Don't thow out a perfectly good phone just because the port stops working..

[–] 1985MustangCobra@lemmy.ca 7 points 5 days ago (18 children)

i never trust shops to fix a phone after working for one. they will purposefully damage other components or take your OEM screen and put an aftermarket screen.

Yeah... be incredibly careful about shoving something with metal bristles into your charging port.

Maybe once a year I get a bit of gunk in my port (hey-oh!). Samsung (presumably all usb c androids?) are generally really good about losing their shit and yelling at you to remove the cable immediately and clean your port.

So when I get home? I just get one of my flossers (for teeth) that tend to have a cheap plastic toothpick attached to it. Works perfect, no liquids, and very minimal risk of damaging the port.

[–] Septimaeus@infosec.pub 17 points 6 days ago

I’ve always used wooden toothpicks because

  1. Common
  2. Made from cheap soft wood: more likely to deform or destruct against metal than most plastics
  3. Cut with the grain: especially soft to anything raking against the sides (like delicate pins)
  4. The uneven “splintery” sides happen to be pretty good at snagging tiny fibers of lint to pull them out as one big ball, requiring fewer swipes

More techniques:

  • clean with port facing straight down to get gravity assist
  • blow across the opening of the port: mild negative pressure + agitation inside cavity vs blowing directly into port (which is generally warned against explicitly)
  • focus on “pinning” lint up against each of the two corners and holding gentle pressure during extraction: these corners of the port have no exposed pins, and happen to be where lint tends to accumulate anyway

I use the pick side from one of those dental flossers to clean mine. Works great and easy to replace.

a simple sewing needle does the job

[–] winkerjadams@lemmy.dbzer0.com 16 points 5 days ago (8 children)

I use a toothpick as the metal could potentially short something

[–] Romkslrqusz@lemmy.zip 5 points 5 days ago* (last edited 5 days ago)

You’re not going to short anything.

The power pins (VCC) on your phone’s USB-C port aren’t “live” at all times, the standard requires communication over CC1 and CC2 to negotiate which side is receiving power and at what voltage. Otherwise, a specific value of resistor needs to be in place between those pins and GND to get “dumb” charging at the original 5V usb standard.

The ideal tool is going to be thin and rigid so that you can get to the base of the port and free up impacted dust/lint. Small enough plastics are going to be to flexible to be effective, anything too thick is going to increase the working time and risk putting pressure against the center tab, potentially damaging it.

I fix consumer electronics for a living, my tool of choice is a pair of ultrasharp tweezers I use for microsoldering. Far as household items are concerned, a real small sewing needle is definitely it. The eye can even be used to catch and pull out fluff.

I would not use metal simply because its hardness is going to be similar or higher than the hardness of the contacts themselves, which means there's a chance it could scratch or break the contact entirely.

Walk into a store? I just use a toothpick or a needle

I used to shock and amaze people when I'd pull out half a cottonballs worth of pocket lint and get their phones working again.

And don't waste $10 on a kit. A toothpick and canned air does everything you need.

I've been using magnetic USB cables and adapters on my devices for years. I occasionally need to clean their connection, but otherwise they work well. Found one I liked and purchased a bunch of them. Now the car, house, office, etc. all have one of the magnetic cables nearby.

They charge a little slower, but that's better for my battery long-term anyway.

At the very least get a toothpick and get the lint out. Like, come on Jamal, there's a reason your charging cable doesn't go all the way in anymore.

Hey thanks for all the tips in the comments, I've got these brand new stiff-ish cleaning brushes and this one worked really well to clean out my charging port and now there's no more beach sand grinding noise when I shove my cable into the charging port.

[–] Buddahriffic@lemmy.world 5 points 5 days ago

You don't want to be too rough on it. There's electrical contacts that can get blocked by dust, lint, and crap, so cleaning helps, but the contacts themselves aren't that thick, so you don't want to wear them down too much while cleaning. A cleaning solution helps loosen up everything with less force and a softer brush/pad is less likely to knock bits of contact off.

So just be careful because that brush might be like blowing in nintendo cartridges (clearing dust but leaving saliva specs that would wear the contacts), where it helps in the short term but makes things worse in the long term (resulting in more blowing and an acceleration of the process).

[–] worhui@lemmy.world 11 points 5 days ago (5 children)

By all means try a tooth pick and pure alcohol, if that doesn't work a professional might get you set straight.

Repair shops can do a better job cleaning than a home option. I had a data and charge problem, bought a kit and tried 3x times; it didn't work . Bought new cables just in case that was the issue. Brought it in for repair fully expecting to pay for a port repair. Repair shop did a through cleaning charged me $15 and sent me on my way with everything working.

You must appease the Machine Spirit. You have to chant the prayers to the Omnissiah, burn the holy incense, and rub the phone in purified oils.

The Machine Spirit must be appeased.

Wireless chargers as your bedside charger will also reduce wear on your charge port so if thats the weak point of your phone that will help it last longer

[–] aramis87@fedia.io 13 points 6 days ago (8 children)

You could also set up wireless charging and put the phone down for a bit.

As an ounce of prevention is worth a pound of cure I recommend those tiny rubber stoppers you see in the photo. They have a peel and stick part that goes under your case which retains the plug on a strip of rubber. That strip might wear out in a few years and rip, but they cost almost nothing to replace (and in fact come in packs).

Phones used to have these things built in, then they stopped in the smartphone era because they didn't look as sleek and futuristic I guess. Now, if you have a case, it once again makes hardly any difference to the appearance.

If we had Atari cartridges in 2025 kids would be buying kits to clean them and blow into them.

My phone is a Galaxy Z-Fold5, not new but not old enough for me to replace since the Fold7 just shipped.

Was hell bent sure the issue causing my phone to begin not accepting charging cables* was something Samsung was doing with their software updates. (*It charged fine with contactless chargers if youre ok with it taking 10-14 hours to charge)

It was too much of a coincidence that the phone charged 100% fine with any and all cables. Download a software update (not android update, this was samsung delivered update) phone doesnt charge with a cable after that for 2-3 weeks. Im T1Diabetic who uses wifi connected glucose monitor, so it fuckin drains battery juice 24/7 with very little setting controls to mitigate it. So I spent 2-3 weeks battling with it to charge on charging pads.

Didn't change a thing with what I was doing and BAM another Samsung update, weirdly close to the last update and fuck me running if the phone didnt start charging very very tenderly with charging cables again.

Eventually figured fuck it, if its hard to do the phone is broke if its easy enough to do then maybe it will help and bought a pack of adhesive rubber type C port plugs from Amazon that came with a super cheap cleaning kit. It wasnt anything special. It came with the picture pointed and spaded q-tips, a flexible wire brush, then I used my own zip tie that I shaped, a sim card tool and a cloth for cleaning glasses. AND WENT TO FUCKING TOWN.

Everytime you plug in your charger to your phone, any dust that is in there is getting buttfucked into the back of the phone's charging port like its a muzzleloaded gunpowder. Lol a bit hyperbplic but you get the point.

Finished cleaning the port. Plugged it in. First fuckin try, no fighting it, no switching chargers, no "charging but not fast charging" bullshit, no more voids in guessing my blood sugar, no more watching tv holding charger into phone. AND $1,000+ THAT IS STILL IN MY FUCKING ACCOUNT.

I gotta assume this is the #1 driver for phones needing to be replaced ever since the screens stopped shattering everytime you sneezed. The adhesive rubber plug is amazing. It is hardly noticeable and stays in the charging port even with my opening and closing of screens. It never pops out.

Honestly the smartest $10 I think I may have ever spent.

TLDR: Phone not charging? Buy $10 type C cleaning kit from amazon, watch 5min video on tips for cleaning, clean charging port for night and day results. Not difficult, very hard to fuck up your phone unless you jackhammer the port cleaning it. Saves you the cost of a new phone.

And obviously this isnt a fix all for all charging issues.
