I am very curious to see the final design and spec's of the Galaxy S4. Rumors were saying it would be almost as thin as the iPhone 5, while also packing a beefy sized 2600mh battery. That would be amazing to see such a thin lightweight phone with a huge battery like that.
And on top of that, the new processor and GPU are supposed to be very efficient, and better for battery life too.
Right now I am all about battery life, phones have gotten fast enough for me, don't need them any quicker, but long battery life is very important, and even better if removable. Couple times a year I go on camping trips, is nice to have replaceable batteries, and then also helpful if the battery itself is large and the phone efficient to last long on a single charge.
I am no iPhone fan, but have to give them credit, on using only a 1450mh sized battery, but that thing can get pretty darn good life out of it. An Android phone with a 1450mh battery would be dead in less than 8 hours.
We need more phones copying Motorola's MAXX style battery, a beefy 3300mh battery, while also going into a thin phone.
When will phones have battery life that last 24 hours, but 24 hours of real world use, not disabling features, or turning stuff off to save battery life. I mean using it for GPS navigation for couple hours a day, make tons of phone calls, have all sync features enabled and running 24/7. I had the Note 2 for three weeks, even that beast of a phone would die on me after 16 - 18 hours with heavy workday use, like two hours worth of phone calls, GPS for 90 minutes, texting like mad, surfing the web non stop, reading and sending e-mails, sync accounts all on. Even that phone couldn't last a full day with that type of heavy non stop use. And I was running a good custom TW ROM, with kernel known for battery life. Sure the Note 2 was great on weekends with WiFi, I would get 36 hours out of it, but on a weekday at work using the phone all day, no way.
