How to Share Wi-Fi from Android to Another Android: All the Methods + Battery Saving Tips

Modern smartphones on Android They can not only connect to Wi-Fi but also become a source of internet for other devices. This feature is useful if you urgently need to share mobile data with a friend, tablet, or even laptop, but don't have a router handy. But how do you set up sharing correctly to avoid speed loss, drain your battery in 10 minutes, and avoid common mistakes? In this article— 3 proven methods share Wi-Fi with Android on the other Android, comparison of their pros and cons, and hidden settings, which are not written about in standard instructions.

Many users experience hotspots suddenly disconnecting, speeds dropping tenfold, or only one device being able to connect. We'll explore why this happens and how to fix it. You'll also learn: How to bypass operator restrictions for Internet distribution (if they are included in your tariff) and What phone models? They perform best as mobile routers. Spoiler: not all flagships are leaders here!

Before you move on to the settings, there are two key points to check:

1. Make sure that on the main phone (the one that will distribute the Internet) mobile Internet is enabled and it works reliably. Try opening any website in your browser.
2. Look, does your tariff allow it? Internet tethering. Some operators block this feature or charge an additional fee. For example, MTS And Beeline In basic plans, data sharing may be limited to 1–2 GB per day.

1. Sharing Wi-Fi via an access point (the most popular method)

This is a classic method that works on all phones with Android 4.0 and newer. Your smartphone turns into a fully-fledged router, and other devices connect to it via Wi-Fi, just like a home network. Key advantages: high data transfer speed (up to 866 Mbps on Wi-Fi 5) and the ability to connect up to 10 devices simultaneously (depending on the phone model).

To turn on the hotspot:

1. Open Settings → Network & Internet → Hotspot & Tethering (on some phones the path may be different: Settings → Connections → Mobile Hotspot).
2. Tap on the item Mobile hotspot (or Portable access point on Samsung).
3. Turn on the switch and, if necessary, configure the network settings:
   • 🔐 Network name (SSID): Come up with a unique name to avoid confusion with other points.
   • 🔒 Password: Use a combination of letters, numbers and symbols (minimum 8 characters).
   • 📶 Range: select 2.4 GHz for better compatibility or 5 GHz for greater speed (if both devices support it).

Once activated, a notification will appear on the screen indicating the number of connected devices. On the second phone, find the new network in the Wi-Fi list, enter the password, and connect. If your hotspot suddenly turns off after 5-10 minutes, check your power saving settings: many phones (especially Xiaomi And Huawei) automatically turn it off to save battery power.

2. Sharing the Internet via Bluetooth: When Wi-Fi is Unavailable

If your phone's Wi-Fi module is broken or you are in a place where Wi-Fi networks are prohibited (for example, on some airplanes or hospitals), you can share the Internet via BluetoothThis method is slower (maximum 3–5 Mbps), but then again saves battery life 2-3 times compared to the access point.

Setup instructions:

1. Turn on Bluetooth on both phones.
2. On your main phone (the one that distributes the Internet), go to Settings → Network & Internet → Hotspot & Tethering.
3. Activate the option Bluetooth modem (or Bluetooth modem mode on Samsung).
4. On the second phone, find the first device in the Bluetooth settings and connect to it. A new option will appear in the list of networks—tap it to connect.

Disadvantages of this method:

• ⚡ Low speed – only good enough for instant messaging and lightweight websites.
• 🔋 The connection may be interrupted if the phones are more than 10 meters apart.
• 📱 Not all applications (for example, YouTube or online games) will work stably.

3. Sharing the Internet via USB cable: maximum stability

This is the most reliable, but least known method. It's suitable if you have a USB cable (usually included with your phone) and need to share the internet with another device. Android- smartphone or tablet with support OTG. The speed is comparable to Wi-Fi (up to 100–150 Mbps), and battery consumption is minimal, as the phone charges while it is in use.

How to set up:

1. Connect the phones via cable. A notification will appear on the main device (the one sharing the internet) informing you that a USB connection has been established.
2. In the settings, go to Network and Internet → Access Point and Modem and turn it on USB modem.
3. On the second phone, in the network settings, select USB Internet (may be called Ethernet over USB).

Advantages of the method:

• 🔌 Stable connection without breaks.
• ⚡ The speed is higher than Bluetooth and comparable to Wi-Fi.
• 🔋 A phone that shares internet is charging, but does not discharge.

Flaws:

• 🔌 A cable is required (not always convenient).
• 📱 Not all phones support USB Internet (especially budget models).

Which phones do not support USB modem?

Among budget models, the problem is more common in Nokia (series 1-3), some Tecno And InfinixThis feature may also be disabled on phones with custom firmware. Check for support in the model's specifications or in the "Access Point" menu settings.

Comparing distribution methods: which one to choose?

To make your decision easier, we've compiled the key parameters in a table:

If you need download a large file or play an online game, choose Wi-Fi hotspot. For messengers or battery saving will do Bluetooth. And if it is important stability (for example, for video calls), take USB cable.

Common problems and how to solve them
