Recently i got a new android smartphone and i want know if its necessary to update android apps frequently.The reason for asking this is
1)does updates for android apps reduce the battery usage?
2)should i update my apps if i don't have much internal memory (i mean will it slow down my phone if there isn't enough internal memory)?
3)will there be any (real) performance improvement if we update apps?
I know that certain updates provide new features,bug fixes(i hope it means errors) and change in the background/layout.Without considering the added feature,bugfixes and layout is it necessary to update?Also each update takes a good amount of internal memory in my phone as well as a lot of valuable mobile data.
