50 Non-Upgradeable Hardware Most components connect direct to circuit boardNo way to upgradeEverything is soldered to a circuit board, sometimes even the battery. This would be non-upgradeable hardware.When a mobile device no longer possesses the capabilities or operates at the speeds required by the user, it must be replaced. Often, old mobile devices can be traded in for credit when purchasing a new one. The items are refurbished and resold or donated. Basic mobile devices can be donated to be reused when they cannot be traded in. Check for local donation programs in your area to find where these devices can be taken.
