Slow Internet in applications on Android is a problem that every second user faces. Video slows down, messages in instant messengers are sent with a delay, and online games constantly lag. The reasons may lie both in the smartphone settings and in external factors: from an overloaded network YouTube slows down, messages in instant messengers are sent with a delay, and online games constantly lag. The reasons may lie both in the smartphone settings and in external factors: an overloaded network Wi-Fi to restrictions from the mobile operator. In this article, we will look 10 proven methodshow to increase the Internet speed in applications by Android โ€”from basic settings to hidden functions that only advanced users know about.

It is important to understand: Internet speed in applications depends not only on test indicators speedtest.net. For example, Netflix can slow down even at a stable 50 Mbit/s due to server limitations, and Telegram will fly at 5 Mbit/s thanks to optimized protocols. Therefore, we will analyze real performance - response time, connection stability and content loading speed within applications.

1. Check the real Internet speed (not only in Speedtest)

The first step is diagnostics. Most users limit themselves to tests like Speedtest or Ookla, but they show maximum speed in ideal conditions, and not what applications receive. To assess the real situation:

  • ๐Ÿ“ฑ Launch the problematic application (for example, TikTok or Google Maps) and note the loading time of the content.
  • ๐ŸŒ Open in the browser fast.com โ€” this service from Netflix tests speed specifically for streaming.
  • ๐Ÿ“Š Use Network Signal Info (application in Play Market) to see ping, jitter (latency variation) and signal strength.

If the speed is Speedtest high, but applications are slow, the problem is most likely in DNS servers, operator restrictions or background processes. If the speed is low everywhere, look for the reason in the network or device settings.

๐Ÿ“Š Which network slows down more often for you?
mobile data (4G/5G)
Wi-Fi at home
Wi-Fi in public places
Both networks are the same

2. Optimize your mobile data settings (4G/5G)

Even if you 5Ghave a smartphone, incorrect settings can โ€œchokeโ€ your speed. Here's what you need to check:

  • ๐Ÿ“ถ Network mode: Go to Settings โ†’ Mobile network โ†’ Network mode and select 5G/4G/3G/2G (auto). If only 4Gis available, try to force enable LTE only โ€”sometimes this speeds up the connection.
  • ๐Ÿ”„ APN profile: Outdated or incorrect settings APN (access points) may limit the speed. Update them manually or request the latest settings from your operator. For MTS, Beeline, MegaFon and Tele2 they are usually available on official websites.
  • ๐Ÿ“ก Roaming: If you are roaming, turn off Automatic network selection and select the operator manually - sometimes the network โ€œsticksโ€ on a weak signal.

Critical nuance: on some smartphones (for example Xiaomi or Samsung with firmware from the operator) the โ€œtraffic saving modeโ€ is enabled by default, which artificially limits the speed of background applications. Disabled in: Settings โ†’ SIM cards and mobile networks โ†’ Data saving APN profile Settings โ†’ SIM cards and mobile networks โ†’ Data saving.

3. Wi-Fi acceleration: from channel to standard

If there are problems with Wi-Fi, start with the router. Even the most powerful smartphone (Samsung Galaxy S24 Ultra or Google Pixel 8 Pro) will not show high speed if the router is not configured correctly. Main parameters for optimization:

Parameter Recommended value Why is it important
Wi-Fi standard 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) Old standards (802.11n) limit the speed to 150โ€“300 Mbit/s.
Channel Auto (or manual 1, 6, 11 for 2.4 GHz; 36โ€“48 for 5 GHz) Overloaded channels cause interference and reduce speed.
Channel width 20/40 MHz (for 2.4 GHz), 80 MHz (for 5 GHz) Larger width = higher speed, but less stability.
DNS servers 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) DNS operator can slow down the loading of sites and applications.

On your smartphone, also check:

  • ๐Ÿ”— Wi-Fi mode: Settings โ†’ Wi-Fi โ†’ Advanced turn on Use Wi-Fi in sleep mode (important for background updates).
  • ๐Ÿšซ Background limitation: Some applications (for example WhatsApp) may be blocked by the system. Check in Settings โ†’ Applications โ†’ [Name] โ†’ Data.
How to find out which Wi-Fi standard your smartphone supports?

Open Settings โ†’ About phone โ†’ Model information and look for mention of Wi-Fi 6 (802.11ax), Wi-Fi 5 (802.11ac) or older standards. If there is no information, check the model specifications on the manufacturer's website (for example, gsmarena.com).

4. Change DNS: why it works and how to set it up

DNS servers are the โ€œphone bookโ€ of the Internet that resolves domains (for example, vk.com) to IP addresses. If the operator or provider's server is slow, delays occur even with a high connection speed. The solution is to use public DNS:

  • ๐ŸŒ Cloudflare: 1.1.1.1 and 1.0.0.1 (the fastest for most regions).
  • ๐Ÿ” Google DNS: 8.8.8.8 and 8.8.4.4 (stable, but sometimes blocked).
  • ๐Ÿ›ก๏ธ AdGuard DNS: 94.140.14.14 (blocks ads and trackers).

How to change DNS to Android:

  1. Open Settings โ†’ Network and Internet โ†’ Wi-Fi.
  2. Click on your network โ†’ Change network โ†’ Additional settings.
  3. In the field DNS select Static and enter addresses (for example, 1.1.1.1 and 1.0.0.1).

Why does this work? Public DNS often have lower ping and do not limit the rate of requests, unlike provider servers. For example, when testing on Samsung Galaxy S23 replacing DNS from Rostelecom to Cloudflare reduced loading time Instagram by 30%.

๐Ÿ’ก

If, after changing the DNS, some sites no longer open, return the settings back - perhaps your provider is blocking alternative servers.

5. Limit background activity of applications

Many applications (especially social networks and instant messengers) consume traffic in the background, even when you are not using them. This not only wastes the Internet, but also creates a load on the network, slowing down basic tasks. How to optimize:

  • ๐Ÿ“ต Data limit: IN Settings โ†’ Applications โ†’ [Name] โ†’ Mobile data disable Background data for unnecessary applications.
  • โšก Adaptive Saving: On Samsung turn on Adaptive Limit in Settings โ†’ Device Maintenance โ†’ Battery.
  • ๐Ÿ”„ Auto-update: Disable automatic app updates in Play Market or limit it only by Wi-Fi.

For advanced users: use ADB-commands to completely block background activity for individual applications. For example, to disable background traffic for Facebook:

adb shell cmd appops set com.facebook.katana RESTRICT_BACKGROUND deny

โš ๏ธ Attention: Blocking background data for instant messengers (WhatsApp, Viber) will lead to delays in receiving messages. Use this method only for non-critical applications.

6. Use a VPN to bypass operator restrictions. Some mobile operators (especially in regions with poor coverage) artificially limit the speed for certain services - for example, for torrents. VPN helps bypass these restrictions by masking traffic.

Some mobile operators (especially in regions with poor coverage) artificially throttlet (limit) the speed for certain services - for example, for YouTube, Twitch or torrents. A VPN helps you bypass these restrictions by masking your traffic.

Recommended VPNs to speed up the Internet:

  • ๐Ÿš€ Warp+ (Cloudflare) โ€” free, low ping, but traffic limitation (1 GB/day).
  • ๐Ÿ›ก๏ธ ProtonVPN โ€” no speed limits, but servers may be overloaded.
  • โšก 1.1.1.1 (Cloudflare) โ€”not a full-fledged VPN, but it speeds up DNS queries.

How to check if a VPN helps:

  1. Run Speedtest without a VPN and record the results.
  2. Connect to a VPN and repeat the test.
  3. Compare the speed of loading content in the problematic application (for example, video buffering time in YouTube).

โš ๏ธ Attention: Some applications (for example, banking or Netflix) block access via VPN. Also, free VPNs can limit the speed themselves after the limit is exhausted.

๐Ÿ’ก

VPN speeds up the Internet only if the problem is due to operator restrictions. If the network is overloaded or the signal is weak, VPN will not help (and may even slow down the connection).

7. Clearing the cache and optimizing the system

Clogged cache, fragmented memory and outdated software can indirectly affect the speed of the Internet. Applications begin to freeze when processing data, and the system wastes resources on unnecessary processes. What to do:

  • ๐Ÿงน Clear cache: Go to Settings โ†’ Storage โ†’ Cache data and click Clear. For individual applications: Settings โ†’ Applications โ†’ [Name] โ†’ Storage โ†’ Clear cache.
  • ๐Ÿ”„ Software update: Outdated versions Android may contain errors in working with the network. Check for updates in Settings โ†’ System โ†’ Software update.
  • ๐Ÿ—‘๏ธ Removing garbage: Use built-in tools (for example, Google Files) or applications like CCleaner to clean up unnecessary files.

On devices with MIUI (Xiaomi, Redmi, POCO) additionally disable advertising services:

  1. Go to Settings โ†’ Memory โ†’ Cleaning.
  2. Disable MIUI Recommendations and Analytics.

โš ๏ธ Attention: On some firmware (for example, ColorOS from Oppo/Realme) aggressive cache clearing can lead to application crashes. In this case, use the built-in Game Space or App Booster for optimization.

8. Alternative methods: from developer mode to replacing the firmware

If standard methods do not help, try advanced settings. They take longer, but can significantly speed up the Internet in applications.

  • ๐Ÿ”ง Mode Developer: Turn it on (click 7 times on Build number v Settings โ†’ About phone), then in Settings โ†’ System โ†’ For developers activate:
    • Do not disable data when the screen is locked (for a stable connection).
    • Limit background processes (set a maximum of 2-3 processes).
  • ๐Ÿ“ฆ Custom ROM: Firmwares like LineageOS or Pixel Experience are often better optimized for working with the network than stock versions from manufacturers.
  • ๐Ÿ“ก Antenna booster: For devices with poor reception (for example, Sony Xperia or some models Motorola), you can use external antennas or signal repeaters.

โš ๏ธ Attention: Installing custom firmware (Custom ROM) will void the warranty and may lead to unstable operation of the device. Before the procedure, make a backup via TWRP or OrangeFox.

How to check if your smartphone supports bootloader unlocking?

Most brands (except Huawei and some models Samsung) the bootloader can be unlocked. Check on the website XDA Developers or through the command:

adb reboot bootloader

fastboot oem unlock-info

If the command returns true, unlocking is possible.

FAQ: Frequently asked questions about Internet speed in applications

Why Speedtest shows 100 Mbps, but YouTube is slow?

Speedtest measures the speed between your device and the nearest server, and YouTube depends on the server load Google, your DNS and operator restrictions. Try:

  • Change DNS to 1.1.1.1.
  • Disable Data saving in settings YouTube.
  • Check if it is enabled Mobile traffic limit in your account Google.
Can a virus slow down the Internet on Android?

Yes, but less often than on a PC. Viruses (for example, Adware or Trojan) can:

  • Consume traffic in the background (advertising, mining).
  • Redirect requests through proxy servers.

Check the device via Malwarebytes or Dr.Web Light. If there are no viruses, but the traffic is going somewhere, check the list of applications in Settings โ†’ Network and Internet โ†’ Data usage.

How to speed up the Internet in games (PUBG, Call of Duty, Genshin Impact)?

For online games it is not so critical megabit/second, how much ping (delay) and jitter (stability). Optimize like this:

  • Use Wi-Fi 5 GHz (less interference than 2.4 GHz).
  • Enable Game mode (available on Xiaomi, ASUS ROG, Black Shark).
  • Disable background applications via Settings โ†’ For developers โ†’ Do not save actions.
  • If playing via mobile data, disable VoLTE (voice over LTE) - it can increase ping.
Does rebooting the router or smartphone help?

Yes, but temporarily Reboot:

  • Resets the cache DNS and network settings.
  • Clears ARP table the router (if many devices are connected).
  • Closes โ€œfrozenโ€ background processes on the smartphone.

The effect lasts from several hours to a day. If the problem returns, look for a deeper reason (for example, overheating of the router or a faulty SIM card).

Which applications โ€œeat upโ€ the Internet in the background the most?

Top 5 โ€œgluttonousโ€ applications (according to data Android Authority for 2026):

  1. TikTok โ€”up to 1.5 GB/hour when scrolling the tape.
  2. Facebook โ€”up to 800 MB/hour (including video autoplay).
  3. Instagram โ€”up to 500 MB/hour (especially Stories and Reels).
  4. Google Play Services โ€”up to 300 MB/day (background updates).
  5. Netflix โ€”up to 3 GB/hour in quality Ultra HD.

Limit background data to it or use Light versions (for example, Facebook Lite).
