Heat is the biggest variable: a phone that charges under a pillow or in direct sun ages faster than one charged on a desk, whatever the brand.<\/p>\n  <\/details>\n  <details>\n    <summary>Does a replacement battery need calibrating?<\/summary><p class=\"ytk-a\">Some handsets report the new cell&#8217;s capacity more accurately after a full charge and discharge cycle, and a few need the part pairing to complete before the gauge settles. Running the phone to shutdown once and charging it fully is the usual approach where calibration applies.<\/p>\n  <\/details>\n  <details>\n    <summary>Is an aftermarket battery as good as a genuine one?<\/summary><p class=\"ytk-a\">It depends on the supplier rather than the category. Some aftermarket cells measure close to genuine and last as long; others meet the label and not the behaviour. The practical test is batch consistency and return rate, which is why buying from a supplier who can show both matters more than the brand on the wrapper.<\/p>\n  <\/details>\n  <details>\n    <summary>What should I do if the old battery is swollen?<\/summary><p class=\"ytk-a\">Treat it as a safety item, not as routine waste.
