How do I improve the battery life on iPhone 5S?

VDubGolf,

See the section "View Battery Usage Information" in the link below to see which apps are consuming your battery:

Maximizing Battery Life and Lifespan

If that is no help, you may want to consider a new battery:

iPhone Battery & Power Repair

Good luck.

Hi

Turn screen brightness down a bit go to settings down to apps refresh turn this off.

If your battery is over 2 years old it will need replacing make an appointment at Apple store.

Oer contact Support.apple.com for posting details use SIMCARD in other phone if you have one.

Go to apps store download Battery life it will test your battery condition.

Cheers
