Just upgraded my S4 to latest version. Now the phone self switches off from time to time.

[AC Question]

The battery is new as the previous battery had died. The battery still will not last more than 10 hours.
As I write this the phone auto shut down again alone.
To reboot I have to remove and install the battery before it will re-boot.
It has got so bad I will have to go to another manufacturer of mobile phones if it cannot be rectified.
The battery seems to be getting very hot. The battery has 53% charge still.
Is there a solution to this problem?

Welcome to Android Central! An overheating battery can be a sign that the battery is failing--try a new or different battery. A corrupt file on the SD card or a corrupt card could also cause behavior like this, so if a different battery doesn't help, try unmounting the card (in Settings>Storage) and removing it, then seeing if the overheating persists.

Another general troubleshooting step would be wiping the cache partition: http://support.t-mobile.com/docs/DOC-5744

The battery is brand new.
There is no SD card involved.
The restart can only be done when I remove the battery and re-insert.

the over heating does seem to be the new battery.
I have wiped the cach thanks

Thanks

New batteries can be defective as well. Can you borrow someone else's S4 battery and test it out?
