Think of LIGHT as a lighter door into the same game, not a different battleground.
| First install | Full PUBG MOBILE is large and grows · LIGHT starts near 1 GB with Erangel |
| Extra content | Full client often pulls more up front · LIGHT lets you add maps and modes later |
| Account | Same PUBG MOBILE login |
| Friends | You can squad with people on the standard client |
| Updates | Meant to ship alongside the main game |
Will you keep both apps? Maybe, if you have the storage. Many phones that struggled to finish the full install will replace it. That is a personal choice, not a rule we can set.
