Then again all of the apps that have been pushed down between google and samsung are sucking up more power than they did when the phone was new and pristine

After charging overnight it did not retain enough power to fully power up my cell phone.

Have used it over the last 3 weeks and it has solved all of the weird power issues with my phone.

Unfortunately I seem to lose power very quickly when using date or being on wifi and my phone is very hot

This is a replacement standard battery for Samsung Galaxy S4 which I desperately needed as my existing one was over-charged creating unexpected sudden power-offs.

A replacement battery for this phone model is IMPOSSIBLE to attain even directly from Samsung's website but Amazon.com enable me to continue usage with a new battery without unexpected sudden power-offs.
