I upgraded my 4s on the premise that it got better battery life just by being on ios9, but it got much much worse. My battery was on the decline before the switch, but I could generally get through a day with just enough juice left at night. Now, I have to have it in LP mode all the time or it will die within a few hours.
- acdha 11y agoThis happened to my 4S as the battery aged, but that was during the iOS 8 era. One thing which made a huge difference was disabling background refresh. If you're not willing to go that far, use the battery menu to disable all but the most important apps. Otherwise, they tend to go things like keep the radio running, which is even worse with the 4S's 3G radio and correspondingly longer times to connect, and especially bad in areas of low signal (e.g. the building I work in).
- matthew-wegner 11y agoFYI, the battery replacement on the 4s is really, really easy (back plate just slides off, versus removing the screen via suction on the later models). It'll cost you $15-25, depending on where you buy. Guide: https://www.ifixit.com/Guide/iPhone+4S+Battery+Replacement/7111 https://www.ifixit.com/Guide/iPhone+4S+Battery+Replacement/7...
