In your experience what&#x27;s the usual time between battery replacements?<p>That&#x27;s been the only &quot;killer&quot; for phones for me. With a decent case I feel like they otherwise last forever.<p>My personal upgrade cycle usually involves someone else&#x27;s (ex: spouse or parent) phone breaking, giving them mine, and buying a new one. Otherwise I&#x27;d probably still be on an iPhone 4.
