iPhone 5s battery on iPhone 5
Is it possible to upgrade the iPhone 5 battery with the iPhone 5s battery?
I mean, same connector or same size ?
I had the same thought (I am also having battery problems with my iPhone 5).
However, after a quick look around the iFixit site it's clear that the iPhone 5S battery is not available for purchase anyway (as of Nov 30, 2013)!
I'm just getting the iPhone5 battery. Even if we assume everything is perfectly compatible (which is a HUGE assumption that will probably blow up in our faces), the percentage change between the 5 and 5S batteries is only 8.33% ((1560-1440)/1440 = 0.08333). Normally, I expect to get ~16 hours of 'general usage' (my iPhone usually dies right before I plug it in at night). In theory, 8.33% would only bring you up to 17 hr 20 min; not exactly a difference what would justify the risky assumptions involved.
Is this a good question?
