Xiaomi from A to Z: how to set up a new smartphone and avoid mistakes

You just unpacked the new Xiaomi โ€” whether itโ€™s the flagship Mi 14 Ultra, the budget Redmi Note 13 or the gaming POCO F6. The first switch is always exciting: youโ€™re looking at a clean MIUI system that can surprise you with its flexibility of settings and confuse you with its abundance of options. But if you approach the process systematically, your smartphone will work faster, safer and last longer without failure.

In this guide, weโ€™ll not only break down the basic setup (which many miss out on at the risk of lags or data leaks), but also the hidden features of MIUI, battery optimization for different use cases, and protection against typical problems from overheating to unauthorized access.

Important: the instruction is relevant for all modern devices Xiaomi, Redmi and POCO based on MIUI 14/15 (including global and Chinese versions of firmware). If you have a model older than 2020, some points may differ - check the version of the software in Settings โ†’ About phone.

1. First Including: What to Do in the First 10 Minutes

When you first press the power button, the smartphone offers you to go through the initial setup wizard, and here many people rush to press "Skip," but this is a mistake โ€” some of the options then have to search in the depths of the menu.

Follow this algorithm:

  • ๐ŸŒ Language and region choices: Install Russia (or your country), even if you plan to use global firmware, and this affects the services available, such as Mi Pay or Mi Home.
  • ๐Ÿ”— Wi-Fi connection. Use your home network, not your mobile Internet, because updates are downloaded faster. Avoid public hotspots at this stage.
  • ๐Ÿ”„ Data portability. If you are switching from another Xiaomi, select Mi Mover (works via Wi-Fi Direct). Android/iPhone Use Quick Migration, but keep in mind that not all settings will be transferred.
  • ๐Ÿ‘ค Mi Account: Without a Xiaomi account, you wonโ€™t be able to use the cloud, find your phone when you lose it, or unlock it after you reset. Sign up right away, even if you donโ€™t plan on syncing.

โš ๏ธ Warning: If you bought a smartphone with your hands, be sure to reset to factory settings (Settings) โ†’ The phone. โ†’ Reset settings.The previous owner may have left a tied Mi Account, which will block you from accessing certain features.

2. Firmware Update: Why You Should Do It Before You Set Up

Many users customize their smartphone first and then think about upgrades. This is wrong: the latest version of MIUI can fix critical bugs, improve autonomy and add new features. For example, MIUI 15 introduced optimization for the Dimensity 9200+ gaming processors, which reduces heat by 15%.

How to update correctly:

  1. Go to Settings โ†’ About the phone โ†’ System update.
  2. Click "Check Updates." If a new version is available, download it.
  3. Connect the charging (the battery should be โ‰ฅ50%).
  4. Click "Install" and wait for the reboot (it will take 5-15 minutes).

MIUI 15Optimization for Android 14, improved multitasking, new notification centerMi 14, Redmi Note 13 Pro+, POCO F6
MIUI 14Reduced power consumption, new widgets, improved cameraMi 13, Redmi Note 12, POCO X5
MIUI 13.5Tablet support, adaptive screen refresh rateMi Pad 6, Redmi K50

โš ๏ธ Warning: If after the update, the smartphone began to warm or discharge quickly, reset the cache (Settings) โ†’ Memory. โ†’ Clear the cache. This will delete temporary files that may have conflicted with the new firmware.

๐Ÿ’ก

Before upgrading, disable VPN and antivirus โ€“ they can block firmware downloads, especially on Chinese models.

Battery Optimization: How to Prolong Battery Life

The battery is the most vulnerable part of Xiaomi smartphones, and even flagship models with a 5,000 mAh battery can run out in a day if you don't adjust the power consumption.

  • ๐Ÿ”‹ Battery mode. Go to Settings. โ†’ Battery โ†’ Battery mode and select: Balanced for most users; Long life if you want to extend battery life (limits charge to 80%); Performance only for games or benchmarks.
