Most of the time something can be fixed with a service, new part, or a handy how-to on the internet. At the same time take care of what you have, you’d be surprised by how long a phone can last when it's kept in a case.
However if you are set on new, then sell or donate your used items to be fixed for someone else. Used items create repair jobs in all communities (local or not) where less and less skilled labour jobs are able to be relied upon. And when something is repaired and sold it opens doors to those who wouldn't otherwise be able to afford laptops, washing machines and the like. So next time it breaks, fix it or find someone who can!
