Ever found yourself panicking to locate your phone’s IMEI when it’s lost? Or frustrated by battery draining faster than expected? The video we analyzed shares 5 game-changing smartphone tricks to solve these exact pain points. After going through it, I’ve added extra insights to make these tips even more actionable.

content：Core Concepts & Authoritative Basis

The IMEI (International Mobile Equipment Identity) is a 15-digit unique code for every phone—telecom regulators mandate this to track lost or stolen devices. According to GSMArena, using IMEI to block a stolen phone is one of the most effective ways to prevent misuse. For OLED screens, black wallpapers save battery because each pixel emits its own light; black pixels are completely off, cutting power use.

Find Your IMEI Number

Dial *#06# on your keypad. The screen will instantly show your IMEI (dual IMEIs for dual-SIM phones). Note this number down—you’ll need it to file a police report or block the device if stolen.

Tame Annoying Notifications

Go to Settings → Notifications. For each app, toggle off unnecessary alerts (like promotional messages from shopping apps). This reduces distraction and saves small amounts of battery.

Cut Unnecessary Data Usage

Head to Settings → Data Usage. Select rarely used apps and turn off background data. Social media or news apps often use data in the background—blocking this can save GBs monthly.

Test Your Phone’s Hardware

Dial *#0*# to open the hardware test menu. Check touch responsiveness (tap all screen areas for dead zones), vibration, sound, and display accuracy. This is critical for second-hand phone buyers.

Save Battery with Black Wallpapers

If your phone has an OLED screen, set a black or dark wallpaper. OLED pixels don’t emit light when black—this can extend battery life by up to 15% (per Android Authority tests).

The video misses that for LCD screens, dark mode reduces eye strain but offers minimal battery savings. A growing trend: Built-in battery saver modes auto-restrict background data—use these for quick wins. Avoid blocking background data for essential apps (like messaging) to not miss updates.
