Is there a free scanner on Android? Google Drive has a built-in scanner: + → Scan. Adobe Acrobat and Microsoft Office Lens are also excellent free options.

Which PDF app uses the least battery? Xodo uses less battery than Acrobat. Disable cloud sync in background apps for marathon reading sessions.
