Time to upgrade the iphones. Being [relatively] cheap, I would like to get last years model around the time the next model releases.
Any suggestions on where to buy secondhand? or even B-stock?
I have bought several used cell phones off e-bay from vendors who specialize in used phones, non were lemons. It kind of comes down to how good is the battery that will come with it.
Right. I am using my husband's 2 year old iPhone 5. And the battery doesn't last that long - certainly not compared to his new iPhone6. I hope to get a 6c/6s this fall.
Do you remember to close all open apps when not using them? Doing so will extend the battery time by quite a bit.
Actually, that can be counter productive on an iPhone (it's behaves quite differently than Android does). iOS very aggressively manages battery conservation.
Two things that can make a difference are to turn off background location tracking in certain apps and turn on background app refresh of the Facebook app.
Here's a good article that going into this in more detail:
