Charging time depends on which Ring model you own and what power source you use

A Ring doorbell with a fully depleted battery takes between 5 and 10 hours to charge completely, depending on the model and whether you use a standard USB charger or a faster one. The Ring Video Doorbell (2nd generation) and Ring Video Doorbell 3 typically charge in about 5 to 10 hours with a standard 1-amp charger. The newer Ring Video Doorbell 4 charges faster — usually 4 to 6 hours — because it has a larger battery and supports higher charging speeds. If you use a 2-amp or higher charger, you can shave off an hour or two from these times.

The actual time also depends on how depleted the battery is when you start. A battery at 20 percent charge will reach 100 percent much faster than one that is completely dead. Most people do not let their Ring doorbell battery drain completely, so your real charging time is often closer to 3 to 5 hours for a partial charge.

Key Takeaways

  • Ring Video Doorbell 2nd and 3rd generation models charge in 5 to 10 hours with a standard charger; the 4th generation charges in 4 to 6 hours.
  • Using a 2-amp charger instead of a 1-amp charger can reduce charging time by 1 to 2 hours.
  • Partial charges (from 20 percent to full) typically take 3 to 5 hours, not the full range.
  • The battery charges faster when the doorbell is not actively recording or detecting motion while plugged in.

What charger you use makes a real difference

Ring doorbells come with a USB cable but not a power adapter. The adapter you choose determines how fast the battery charges. A standard 1-amp USB charger — the kind that comes with many older phones — will charge your Ring doorbell, but it is the slowest option. A 2-amp charger (often labeled as 2A or 2000mA) cuts charging time noticeably. A 2.4-amp charger or higher will charge even faster, though the improvement levels off after 2 amps because the Ring doorbell's charging circuit has a limit.

You do not need to buy a special Ring charger. Any USB-A charger rated for 2 amps or higher will work. Phone chargers from the last five years are usually 2 amps or faster. If you have an older charger that came with a device from 2015 or earlier, it is probably 1 amp, and you will see noticeably slower charging.

Wall outlet location also matters slightly. Charging over a longer USB cable (6 feet or more) can slow the charge by a small amount because of voltage drop in the cable. A short, high-quality cable and a charger plugged directly into the wall will give you the fastest charge.

How to check your Ring doorbell's battery level while charging

Open the Ring app on your phone and tap the device you are charging. Go to Device Health, then look at the Battery section. The app shows a percentage and sometimes a status like "Charging" or "Good." This percentage updates every few minutes, so you can watch progress without unplugging the doorbell.

The battery percentage does not always climb at a steady rate. You might see it jump from 30 percent to 50 percent quickly, then slow down as it approaches 100 percent. This is normal — lithium batteries charge faster in the middle of their range and slower at the very end to protect the battery's lifespan.

Why your Ring doorbell charges slowly sometimes

If your Ring doorbell is taking longer than expected to charge, the doorbell itself is probably still recording or detecting motion. Every time the doorbell detects a person, package, or motion, it uses power while simultaneously trying to charge. This slows the charging process noticeably. If you need a faster charge, temporarily disable motion detection or move the doorbell away from high-traffic areas while it charges.

Cold temperatures also slow charging. If your doorbell is in a cold garage or outdoor location below 50 degrees Fahrenheit, the battery charges more slowly. Bringing it indoors to room temperature for charging will speed things up. Extremely hot temperatures (above 95 degrees) can also slow charging as a safety feature to protect the battery.

A damaged or worn-out battery will charge slowly no matter what charger you use. If your Ring doorbell takes significantly longer than the times listed above, and you have ruled out motion detection and temperature issues, the battery may need replacement. Ring sells replacement batteries separately, and they are straightforward to swap out.

Charging time for Ring doorbells with wired power

Some Ring models can be hardwired to your home's existing doorbell wiring instead of relying on battery power. If your Ring doorbell is hardwired, it does not need to charge from a USB cable — it draws power directly from your home's transformer. In this setup, the battery still exists as a backup, but it charges continuously whenever the doorbell is powered on.

Hardwired Ring doorbells charge their backup battery much more slowly than USB charging because the transformer supplies only a small amount of current to the battery. A hardwired battery might take 24 to 48 hours to reach full charge, but it does this passively in the background. You do not need to do anything — the battery charges whenever the doorbell is powered on and the battery is not full.

Planning ahead so your doorbell does not die

Ring doorbells typically last 6 to 12 months on a single charge, depending on how much motion and activity your doorbell detects. A doorbell in a quiet area might go a full year. A doorbell on a busy street or near a frequently used entrance might need charging every 3 to 6 months. The Ring app sends a notification when the battery drops below 20 percent, giving you time to charge before it dies completely.

If you know your doorbell is going to need charging soon, start the process during a time when you do not mind being without a doorbell for a few hours. Charging overnight is a common approach — plug it in before bed, and it will be ready by morning. If you have a hardwired doorbell, the battery charges in the background, so you do not need to plan anything.

Frequently Asked Questions

Can I use my Ring doorbell while it is charging?

Yes, your Ring doorbell will still record video and detect motion while plugged in. However, it charges slower when actively recording because the battery is supplying power to the camera and sensors at the same time it is receiving charge. For the fastest charge, disable motion detection temporarily or move the doorbell away from high-traffic areas.

What happens if I leave my Ring doorbell plugged in for days?

Nothing bad happens. Once the battery reaches 100 percent, the charging circuit stops supplying power to prevent overcharging. Your Ring doorbell can stay plugged in indefinitely without damaging the battery. Many people leave their doorbells on a charger during winter months when activity is low.

Is it normal for my Ring doorbell to get warm while charging?

Slight warmth is normal, especially with a 2-amp or higher charger. If the doorbell becomes too hot to touch comfortably, unplug it and let it cool down. Excessive heat can indicate a problem with the charger or the battery itself.

Do I need to fully drain the battery before charging?

No. Modern lithium batteries like the one in your Ring doorbell actually last longer if you avoid complete drains. Charging from 20 percent to 100 percent is fine and is actually better for battery lifespan than waiting until the battery is completely dead.

Why does the Ring app show my battery is still charging after 10 hours?

Check that you are using a charger rated for at least 1 amp. If you are using a very old or low-power charger, it may take longer than 10 hours. Also verify that motion detection is disabled — active recording slows charging significantly. If neither of these is the issue, your battery may be worn out and need replacement.
