Why Your Phone Battery Degrades Over Time — The Real Chemistry Behind It
What's actually happening inside the battery, and what genuinely slows it down
Battery degradation isn't vague "wear and tear" — it's a specific, well-understood chemical process driven mainly by heat and time spent at extreme charge levels. Here's the real mechanism and what helps.
