The Vivo X300 Ultra offers moderate repairability with a mix of accessible components and adhesive-related challenges. The back cover is secured with adhesive making initial entry more difficult and the battery is also glued in place. However battery replacement is helped by easily accessible battery connectors and the inclusion of pull tabs for safer removal. The screen and its cable can be accessed and removed without dismantling many internal components which improves display repairability. On the downside several plastic covers over the motherboard areas must be removed to reach internal cables adding extra disassembly steps. Overall the device balances decent internal accessibility with some common modern smartphone repair obstacles related to adhesive and layered protective covers.
