Turn on airplane mode and close background apps

The fastest way to speed up charging is to stop your tablet from using power while it charges. When you enable airplane mode, your tablet stops searching for cellular signals, connecting to Wi-Fi, and running location services — all things that drain the battery and generate heat while charging happens.

Close any apps running in the background. On most tablets, swipe up from the bottom of the screen and hold, then swipe left or right through open apps and close them. Apps like email, social media, and streaming services keep running even when you are not looking at them, and they pull power away from charging.

Turn off Bluetooth, GPS, and push notifications while charging. These features stay active even in airplane mode on some tablets, so check your settings and disable them manually if airplane mode alone does not work.

Key Takeaways

  • Airplane mode and closing background apps reduce power draw, letting the charger send more current to the battery instead of powering active features.
  • Using the original charger or a high-amperage replacement (at least 2 amps) delivers more power per minute than a low-power charger.
  • A cool tablet charges faster than a warm one, so remove the case, avoid direct sunlight, and let air circulate around the device.
  • Charging from a wall outlet is faster than charging from a computer USB port or a car charger, which deliver less power.
  • Avoid using your tablet while it charges, since screen brightness and processing power pull current away from the battery.

Use the original charger or a high-amperage replacement

The charger that came with your tablet is designed to deliver the maximum safe current your battery can accept. If you have lost it, buy a replacement with the same voltage and amperage rating — usually printed on the original charger or in your tablet's manual.

Look for a charger rated at least 2 amps (2A) or higher. Many phone chargers are 1 amp or less, and they will charge your tablet much more slowly. If your tablet originally came with a 3A or 4A charger, a replacement at that rating will charge faster than a 2A charger.

Avoid cheap third-party chargers with no amperage rating listed. They often deliver less power than advertised and can damage your battery over time. Stick with the manufacturer's charger or a reputable brand that publishes its specifications.

Remove the case and keep the tablet cool

Cases trap heat around your tablet, and heat slows charging. When your tablet gets warm, the battery management system automatically reduces the charging speed to protect the battery from damage. Remove the case while charging, especially if you are charging from a low-power source.

Keep your tablet away from direct sunlight, heat vents, and warm surfaces. Do not charge it in a car on a hot day or near a radiator. If your tablet feels warm to the touch while charging, unplug it, let it cool for a few minutes, and plug it back in.

Make sure air can flow around the tablet. Do not charge it under a pillow, blanket, or in a closed bag. Prop it up at an angle so air circulates on all sides.

Charge from a wall outlet, not a computer or car

Wall outlets deliver the most power. USB ports on computers and car chargers deliver much less — usually 0.5 to 1 amp compared to 2 to 4 amps from a wall charger. If you have a choice, always plug into a wall outlet.

If you must use a car charger, buy one rated for tablets, not phones. Phone car chargers typically deliver 1 amp or less. A tablet car charger should be rated 2 amps or higher.

Avoid charging through a USB hub or extension cable. These add resistance to the power flow and reduce the current reaching your tablet. Plug the charger directly into the wall outlet.

Disable fast-draining features during charging

Screen brightness is one of the biggest power drains. Lower your brightness to the minimum readable level while charging, or turn on auto-brightness and let the tablet adjust it. A dark screen charges faster than a bright one.

Turn off video playback, gaming, and video calls while charging. These activities use the processor and screen heavily, pulling power away from the battery. If you need to use your tablet while it charges, stick to reading or light tasks.

Disable automatic updates and cloud syncing. These run in the background and consume power. Check your settings for Google Play Store updates, iCloud sync, OneDrive, or other cloud services and pause them until charging is complete.

Check the charging port and cable for damage

A loose or dirty charging port slows charging because the connection is not find. Look inside the port with a flashlight. If you see lint, dust, or debris, use a dry cotton swab or a soft brush to gently clean it. Do not use water or metal objects.

Inspect the charging cable for cracks, fraying, or bent connectors. A damaged cable delivers less power and may not charge at all. If the cable is visibly worn, replace it with a new one rated for your tablet.

Try a different cable if you have one available. Sometimes a cable that looks fine is damaged inside and delivers poor power. Swapping cables is a quick way to rule out cable problems.

Avoid charging to 100 percent every time

Charging to 100 percent slows down in the final stages. Most tablets charge quickly from 0 to 80 percent, then slow down to protect the battery as it approaches full capacity. If you are in a hurry, unplug at 80 percent and use your tablet — you will get most of a full day of use.

For everyday charging, stopping at 80 percent also extends your battery's lifespan. Lithium batteries last longer when they spend less time at high charge levels. If you need the full charge for travel, charge to 100 percent, but for daily use, 80 percent is faster and healthier for the battery.

Frequently Asked Questions

Does turning off Wi-Fi and Bluetooth really make charging faster?

Yes, but the effect is small — usually a few minutes over a full charge cycle. The bigger benefit is that airplane mode stops your tablet from searching for networks and processing incoming data, which generates heat. Less heat means the battery management system does not throttle charging speed.

Can I use a phone charger to charge my tablet?

You can, but it will charge slowly. Phone chargers are usually 1 amp or less, while tablets need 2 to 4 amps for fast charging. Using a phone charger is safe, just slower. If the connector fits, the voltage is correct, and the charger is in good condition, it will not damage your tablet.

Why does my tablet charge slowly even with the original charger?

Check the charging port for lint or debris, inspect the cable for damage, and make sure airplane mode is on and background apps are closed. If the tablet feels warm, let it cool down before charging again. If it still charges slowly after these steps, the battery may be aging and losing capacity.

Is it safe to use my tablet while it is charging?

It is safe, but it slows charging significantly. Using the screen, apps, and processor pulls power away from the battery. If you want the fastest charge, do not use the tablet. If you must use it, keep the screen dim and avoid heavy tasks like video or gaming.

Does fast charging damage the battery?

No. Tablets are designed to handle their rated charging current safely. Using the correct charger at the correct amperage will not damage the battery. What does damage batteries is heat, so keeping your tablet cool while charging is more important than the charging speed itself.
