# Tips for Checking Dead Pixels When Buying New Electronics - **Test with Full Screen Colors:** Make your screen completely white, black, red, green, or blue using paint, a website, or full-screen images (F11). This makes dead or stuck pixels easier to spot. - **Use Multiple Colors:** Cycle through different colors to identify anomalies like stuck pixels. - **Official Standards:** Dead pixels are normal; displays are rated by ISO 13406-2 standards, with Class I having no dead pixels, and Class II allowing a few. Avoid Class III or IV. - **Return Policies Matter:** Buy from vendors with good return policies; many allow returns without reason within a certain period, especially online. - **Check Before Purchase:** Inspect for dead pixels on arrival; consider using dedicated test videos on YouTube or specialized websites like [Eizo Monitor Test](https://www.eizo.be/monitor-test/). - **Be Vigilant During Travel:** When packing fragile electronics or screens, test immediately after unpacking to detect potential damages from transit. - **Know Your Rights:** Minor defects like dead pixels are often considered returnable issues, especially under regulations like EU’s "free from minor defect" rule. - **Avoid Accepting Faulty Displays:** Some stores claim an "acceptable limit," but many argue zero dead pixels should be standard. Don’t settle—return if defective. - **Post-Black Friday Strategies:** Wait until after sales to buy electronics at a better price and ensure they've been thoroughly checked. - **Additional Tips:** For laptops, monitors, or TVs—examine carefully upon receipt. If defective, contact customer service or file chargebacks if necessary.

# Tips for Extending Your Apple Watch Battery Life - Enable **theatre mode** to significantly prolong battery life — from 1 day to up to 3 days. - **Theatre mode** still tracks activity and receives notifications, but the screen remains off unless tapped. - Turning on theatre mode is especially useful when your watch is low on battery and you can't charge soon. - **Hard reset** the watch if it starts draining battery unexpectedly: hold down the crown and side button until reboot. - **Reduce unnecessary communication**: limit background app activity and disable notifications you don’t need. - **Unpair and repair** the watch if battery drain occurs after updates or prolonged inactivity — it can resolve connection issues causing power drain. - Consider turning off **activity sharing notifications** or removing all non-essential apps to improve battery longevity. - Keep in mind that an old battery or software glitches could cause rapid drain; regular maintenance or replacement may be necessary.
