10 reasons why your Android battery is charging slowly and how to fix them
Is your phone battery suddenly taking significantly longer to charge? Maybe your phone has always taken ages to reach 100%! Whatever the case may be, there are some things you can try to help your handset charge faster. Check out these solutions to see if one of them can help your situation.
Editor’s note: Some of the instructions in this article were put together using a Google Pixel 7 Pro running Android 13. Some steps might differ depending on your hardware and software.
Is your cable in good condition?
A faulty cable is often the reason why your smartphone battery might be charging slowly. Especially if it’s a charging cable you’ve owned for a long time. These accessories go through plenty of torture during their lifetime. You take them on trips, step on them, tangle them up, throw them in bags, etc. Inspect your charging cable carefully and see if there are any signs of significant wear and tear. Any rips, bends, scratches, or damage may be the culprits. Sadly, the only solution to this issue is simply buying a new cable! Here are some of our favorite USB cables.
How about the adapter?
The same goes for the adapter, otherwise known as a charging brick. This is the accessory that plugs into the wall. Check that there isn’t any significant damage. Any bent plugs or cracked sections may be a sure sign that something’s wrong with it. If you need a replacement, here’s a list of the best wall chargers around.
Don’t forget the charging port
Maybe your phone is the issue, and one of the most common reasons for a slow charging battery is something as simple as a dirty smartphone charging port. Look in there and see if you can spot any debris. Try to clean it out with compressed air or a small brush. Also, have you noticed the port or charger feeling looser than before? Sometimes these ports get worn out, and contacts may not be as solid, causing the battery to charge slower. Don’t forget to look for any signs of corrosion.
You might have a weak power source
This is likely not an issue if you’re using the stock charger and cable, but it could be if you’ve decided to charge your battery with something other than an outlet. Sometimes people like charging their phones using USB ports on laptops, portable batteries, cars, and power strips. These can often be weak sources of power, and don’t have the necessary juice to charge up your device in a timely fashion. Try switching to a wall outlet and using a fast enough charger for your phone’s standards.
Use the right charging accessories
Have you switched chargers or cables since you got your phone? This could be why your phone’s battery is taking ages to charge. There are different types of fast charging in the market. You can learn all about them in our dedicated fast-charging post. Still, some include USB Power Delivery, Qualcomm Quick Charge, Motorola Turbo Charge, MediaTek Pump Express, OnePlus Warp Charge, HUAWEI SuperCharge, and Oppo’s SuperVooc, among others.
More often than not, these are incompatible with each other. In addition, your phone might not even be able to handle fast charging! And if it does, there’s also a slight chance that your manufacturer didn’t include a fast-charging cable/adapter. Look into your phone’s specs and get the correct charging accessories! And keep in mind not all wireless charging is made the same, either. Some wireless chargers are faster than others!

Keep an eye on your apps
The screen is known for being the #1 battery-sucker, but rogue apps can do much more to kill your battery and keep it from charging quickly. Android apps often boot themselves up or run in the background after only being opened for a moment. Although this used to be a bigger problem than it currently is — Android is getting better at efficiently managing resources — having a rogue app or two can give your phone’s performance a nasty hit.
Your best bet is to close the app, limit its background activity, or uninstall it.
How to check which apps are using too much battery:
- Open the Settings app.
- Go into Battery.
- Hit Battery usage.
- Go through the list of apps and check if any apps use more energy than they should.
- Tap on the app to Force stop it or Uninstall it.
Are you using the phone while charging?
If you’re a heavy user and don’t stop using your phone all day, chances are you aren’t letting it rest while charging either. Using your handset while plugged in may take too many resources and cause your battery to charge slower. Give it a break! Maybe use a tablet or any other device in the meantime.
The battery could be dying
If you’ve had your phone for a long time and given it hell, this has probably taken a toll on your battery. Batteries, inevitably, degrade over time. They do so faster if you go through many cycles, use them heavily, and let them run hot. Check out the post linked in the previous section to learn tips on keeping your battery healthy as long as possible.
If your phone’s battery is starting to die, the sad news is there isn’t much you can do about it. You could replace the battery if you have a phone with a removable battery, but those are rare these days. You could buy a new phone, otherwise. Here are some of our recommendations for the best Android phones and the best budget options.
Factory data reset
One last thing to try before letting go of your old phone could be a factory data reset. This process deletes everything on your device and gives it a clean start. It will essentially leave your handset the same way it was when you first turned it on (at least software-wise).
But why would this improve slow charging? Sometimes apps and phone processes take a toll on your phone’s resources, and it may be hard to pinpoint what’s going on, exactly. Is the GPS too active? Maybe the problem is a system app, or one of your dozens of apps is going nuts on you. Whatever the case, a factory data reset will get it all back to stock. Try it. And if the phone is still charging slowly after a complete wipe, the issue is probably hardware-based.
How to factory reset your Android phone:
- Open the Settings app.
- Go into System.
- Select Reset options.
- Tap on Erase all data (factory reset).
- Tap on Erase all data.
- Enter your PIN.
- Confirm by selecting Erase all data.
Is it time to upgrade your phone?
As sad as this may sound, every device comes to its end of life. If your phone is struggling to charge (and hold a charge), and you’ve tried all the methods above with no success, maybe it’s time to let it go, finally. Look at the options in the link below if you want to see some true battery beasts.
