So your Samsung Galaxy A36 won't charge. You've plugged it in, maybe even tried a different cable, and the screen stays dark. It's a frustrating spot to be in, especially since Samsung stopped including a charger in the box with the A36. The good news is, this is almost always something you can fix yourself without a trip to the repair shop.
Let's start with the quickest fix, which solves the problem more often than you'd think.
Force Restart Your Galaxy A36
A simple force restart can clear out a temporary software glitch that's preventing the phone from recognizing it's plugged in. It takes about 10 seconds and doesn't delete any of your data.
For the Galaxy A36, press and hold the Volume Down button and the Power button at the same time. Keep holding them for about 10 seconds, or until you feel the phone vibrate and see the Samsung logo appear on the screen.
Once it boots back up, plug in your charger and see if the charging indicator shows up. If it does, you're all set. If not, we'll move on to the next most common culprit.
Clean the USB-C Charging Port
This is the number one physical cause of charging problems. Lint, dust, and pocket debris get packed into that USB-C port every single day. Eventually, there's so much gunk in there that the cable's connector can't make proper contact with the phone's internal pins.
Grab a bright light and take a close look inside the port. If you see a little gray or black mat of lint, that's your problem. Turn the phone off first for safety. Then, take a wooden toothpick or a plastic flosser pick and gently scrape around the sides and bottom of the port.
Be very careful not to use anything metal, like a paperclip or SIM ejector tool, as you can easily scratch or damage the delicate charging contacts. After you've loosened the debris, tap the phone gently with the port facing down to shake it out. A quick blast of compressed air can help too, but hold the can upright and use short bursts.
Check Your Cable, Adapter, and Outlet
Since the A36 doesn't come with a charger, you're probably using an older one or a third-party option. You need to systematically test each part of your charging setup to find the weak link.
First, try a different USB-C cable if you have one. Cables fray and fail over time, especially at the ends. Next, try a different wall adapter. Plug your known-good cable into a computer's USB port or a different power brick. Finally, try a different wall outlet altogether.
It's also worth removing your phone case. A thick or poorly designed case can sometimes prevent the USB-C plug from being fully inserted into the port. If your phone charges fine without the case, you've found the issue.
Use a Powerful Enough Charger
The Galaxy A36 supports up to 45W wired charging, but it won't reach those speeds with just any old adapter. You need a charger that supports the USB Power Delivery (USB-PD) PPS standard.
If you're using a very low-wattage charger, like a 5W or 10W block from an older device, your phone might charge incredibly slowly or not register a connection at all. I'd recommend looking for a charger that's at least 25W and explicitly lists USB-PD PPS support for the fastest, most reliable charging on your A36.
Check for Software Updates
Software bugs can sometimes interfere with the charging system. Samsung has been rolling out updates for One UI 7 to fix various initial bugs reported after launch. Installing the latest update could resolve your charging issue.
Go to Settings > Software update and tap "Download and install." Make sure your phone has at least 30% battery or is plugged in while you do this. If your phone won't turn on to check for updates, you might need to use Samsung's Smart Switch software on a computer later.
Check Your Battery Protection Settings
Samsung includes a feature to help your battery last longer by limiting the maximum charge. If your A36 is charging but seems to stop at 85%, this is almost certainly why. It's a great feature for battery longevity, but it can confuse you if you're not expecting it.
To check, go to Settings > Battery and device care > Battery > More battery settings. Look for "Protect battery" or a similar option. If it's toggled on, your phone will stop charging at 85%. Toggle it off if you need a full 100% charge for the day ahead.
Let a Dead Battery Sit on the Charger
If your battery has been completely drained to zero percent, it won't show any signs of life immediately when you plug it in. This is a safety feature of modern lithium-ion batteries. Don't panic.
Plug it into a wall charger (not a slow computer port) with a good cable and adapter, then leave it alone for at least 30 minutes. Don't keep trying to force restart it during this time. After a half-hour, check to see if a charging icon or percentage appears on the screen. If it does, let it charge to at least 10% before trying to turn it on.
Charge with the Phone Powered Off
If a background app or process is misbehaving, it could theoretically prevent proper charging. You can rule this out by turning your Galaxy A36 completely off. Hold the Power button, then tap "Power off" on the screen.
Once the screen is completely black, plug in your charger. If you see a large battery icon with a percentage, it's charging normally. This also happens to be the absolute fastest way to charge your phone, as no system resources are being used for anything else.
Consider a Factory Reset (Last Resort)
If you've tried every other step and your phone still refuses to charge reliably, a deeper software issue might be at play. A factory reset will wipe your phone back to its original settings, so this is a last resort. Make sure you have a recent backup before proceeding.
You can initiate a reset through the settings if your phone is working. Go to Settings > General management > Reset > Factory data reset. If your phone won't turn on at all, you can often enter recovery mode. Turn the phone off, then press and hold the Volume Up and Power buttons together until the Samsung logo appears, then release. Use the volume keys to navigate to "Wipe data/factory reset" and select it with the power button.
After the reset is complete, set the phone up as new (don't restore from a backup just yet) and test the charging immediately. If it works, you confirmed it was a software glitch. If it still doesn't charge after a full reset, the issue is likely hardware-related.
