Digital communication.

My phone's inability to hold a decent charge is starting to grate on me. I don't use it for a whole lot of things or for many minutes throughout a given day, and based on the stats provided by said phone, the things that I use it for the most - the phone function itself for calls, the CitiBike app, and the home and lock screen - are fairly baffling that they're taking up the most energy. I can't claim to understand the details of the technology involved, but I can claim to be confused that using this phone as a phone is a major drain.

I'm not replacing it, though, not unless I can get the exact same model in the exact same color. I'm holding out until I've got no choice in the matter. Hopefully by then, technology's going to have advanced to the point I can replace the battery myself.
