Hi guys, I recently got a new iphone 4s completely new and with ios 7.1.2 for cheap. I always heard iphones compared to android phones have amazing sleep time, like the most popular technology youtuber MKBHD says in his videos it only drops like 2 percent overnight, etc. However, my iohone 4s dropped 15 percent last night and it seemed like it pulled 3 email notifications and thats it. My signal is perfect at home, and wifi was on. Do you know if this is normal on ios 7.1.2? Thanks.
