Does iOS kill my iPad App if not used by user for a long time?

Question

Suppose I am using one App (no other App is active). Now I lock the iPad by simply clicking the lock button or may be I put it in background mode and put my iPad somewhere.

After what amount of time, the App will get killed automatically by system if I don't use that App? Is there any specification by Apple or we cannot say anything that App will launch from scratch in some scenarios.

Note that in any scenario, I don't kill my App manually.

Answer 1

iOS generally (at least in current versions) doesn't kill apps after some arbitrary time. It kills them when it needs to free up resources. Since modern iPads have quite a bit of memory, that means that apps can stay in the background for a very long time depending on how the iPad is used. As Andreas notes, however, there are no promises about that.
