My more than 8 years old Motorola Defy begs to differ, as does the equally old Ainol Novo tablet I bought around the same time. Both devices run Android 4.4, an older but still usable version for which new software is still produced. The Defy has a replaceable battery, the Novo does not but both still work fine on the original versions albeit with a certain loss of stamina (Defy: 3 days on a charge, Novo ~4 hours of actual use/about a week standby).

In other words, yes, you could and can get Android devices which last for a long time. I does not need saying that both the Defy as well as the Novo were far less expensive than the 'equivalent' Apple devices - where 'equivalent' means 'iPhone 4' for the Defy and nothing for the Novo as Apple at that time did not have a mid-sized (8" 1280x768) tablet.
