If you're using a Samsung Galaxy in Canada , the most practical way I’ve found to monitor day-to-day battery health is through Samsung’s built-in Device Care menu. I’ve tested this across a Galaxy S24 Ultra on Rogers, an S25 demo on Bell, and my older A54 running on Telus — and in all three cases, Device Care offered the clearest view of how the battery behaves in Canadian weather and network conditions. This guide walks you through what the menu actually shows and how to interpret it properly. Why Device Care Matters on Canadian Samsung Models Device Care is one of those menus that many people overlook, but it’s the fastest way to understand real-time battery behaviour. Unlike Samsung Members’ full diagnostics — which are great but slightly slow and sometimes limited by carrier firmware — Device Care gives instant access to app drain, background activity, and temperature-related efficiency drops. In Canada the feature is even more valuable because our mix of col...

If you’re using a Samsung Galaxy in the United States , the most reliable way I’ve found to check day-to-day battery health is through Samsung’s built-in Device Care . On my Galaxy S24 Ultra (AT&T) and an A55 I tested on T-Mobile, Device Care consistently gave me the clearest picture of how the battery was wearing over time—especially after long 5G usage or hot summer charging. If you're on Verizon, AT&T, T-Mobile, or US Cellular, this walkthrough explains what the menus actually mean and how to read the signs of battery aging correctly. Why Device Care Matters for U.S. Samsung Models Device Care isn’t just a battery menu—it’s Samsung’s internal diagnostic layer that U.S. carrier models rely on. Because many U.S. units restrict dialer codes and optimize differently for 5G, Device Care tends to be more accurate than third-party tools. And here’s something I noticed: heavy 5G switching, warm outdoor temps (Texas heat punished my S24), and fast charging all c...

Tesco Mobile “No Service” in My Area UK: A Personal Experience and What I Learned I never thought I’d be staring at “No Service” on my phone in Crawley — not once, but repeatedly. This wasn’t a fringe moment or a fleeting glitch; it was persistent enough that I started hunting down patterns, testing settings, and talking to friends in Brighton and Worthing facing similar issues on Tesco Mobile UK. At first it felt like bad luck. Then it felt like a flaw. Finally, it became a puzzle worth dismantling. The First Time It Happened It was a damp Wednesday afternoon. I was expecting a call, and yet my phone said no bars. No “3G, 4G or 5G”. Just “No Service”. Signal icons can lie, but this was literal. Nothing registered. At that moment, I didn’t know if the problem was: Tesco Mobile The mast near Three Bridges station My phone (I was using a Samsung Galaxy A-series at the time) The SIM So the first lesson I learned — the hard way — is this: “No Service” isn...
