What else can I do to make my iPhone 4S work for as long as possible?
I have done all the "standard" battery saving techniques recommended on most sites, like:
- turn off background app refresh, automatic updates
- lower brightness all the way / disable auto brightness
- keep bluetooth and cellular Off always. Rarely use WiFi.
- No dynamic backgrounds.
The battery is still dying way too quickly. My Battery Usage indicates that the Home and Lock Screen are using 30% of the battery. How is that possible? What is it doing??
