Looking for honest real peoples review or opinions on this subject please. I used to be an iPhone guy back with the first iPhone, and the 3G, then I got attracted to what Android was doing, and moved on to a Nexus-S, and few months ago a Galaxy-Nexus. I do like the larger screens of the Nexus phones, and the Widgets and customization is really cool. But the battery life is becoming a deal breaker for me. I have the extended battery on my G Nexus, and rooted with great ROM, and the battery life still sucks, maybe 9 - 10 hours a day. If a busy workday then maybe just 6 hours total battery life, which is unacceptable to me. Other little things annoying me too, with Android, it is still laggy in some places, and touch screen response is hit or miss, sometimes I have to press an app two or three times to activate it. I haven't played with an iPhone since the 3G. Would you recommend the 4S over a G Nexus ? Is the battery life night and day better, or just slightly barely better ? Jailbreaked would be the only iPhone for em, I love to customize my phone and make it look different than stock. Is jailbreaking easy to do, and setting it up custom ?
