If you’ve ever had a reminder fire while your phone was silenced, you know the problem: you get a polite notification at the exact wrong moment, and it disappears into the chaos. 

For some tasks, “polite” is not good enough. Paying a bill. Joining a call. 

Taking medication. 

Leaving for the airport.

Here's a Cool Tip:  Try the new Urgent Alarm feature in the Reminders App.

iOS 26.2 lets Reminders schedule an alarm for tasks you mark as Urgent, including when your device is silenced or a Focus mode is active.

You have probably stared at that tiny battery icon in the corner of your Windows 11 taskbar, trying to guess whether you have enough juice to finish a meeting or a flight. 

The old monochrome icon did not help much. 

It was small, vague, and forced you to click just to see the percentage.

Here's a Cool Tip:  The New Battery Colors Make Power Status Obvious.

A recent Windows 11 update changes that experience with a more colorful, more informative battery indicator. Green, yellow, and red now signal your power situation at a glance, and a clearer percentage readout makes it easier to plan your next charge. 

It is a subtle change that can have a big impact on how confidently you use your laptop away from an outlet.

Turn Excel Into Your AI Teammate: How To Use Agent Mode In Excel For The Web

You know that feeling when a “quick” spreadsheet tweak quietly eats your entire afternoon? 

One more column, one more formula, one more chart, and suddenly you are deep in a maze of references and formatting.

Here's a Cool Tip:  Use Agent Mode in Excel for the Web

Instead of nudging Copilot one prompt at a time, you describe the outcome you want, and Agent Mode plans, builds, and revises a multi-step workflow inside your workbook. 

It behaves less like a chatbot and more like a junior analyst who can explain what it is doing as it goes.

Here's a Cool Tip:  Try Google Gemini's New Personal Intelligence.
