Suppose it depends on what electronics you carry and how much you use them.
I use my iPod a few hours a day at the end of the day to get through the last painful kms and on days off to relax, mobile when in range for about 1 hour a day to update social media and check in and take photos, sat phone when mobile is out of range for 1 hr to check in and do some basic comms each night and a couple of completely unnecessary gadgets. For me it is worth it otherwise I'd be carrying lots of batteries while weeks between reliable AC power.
Plus, I can use it while kombi camping between walks
