iPhone is different. It's well knows that iOS devices have better battery life. Lets compare Android with Android - which as we all know doesn't manage power very well ( at least not as good as iOS or Windows Phone ). I'm pretty sure you'll be able to get 4h+ screen time - it depends on what Spectre has been doing with his phone.

Yeah I guess so, I was just dissapointed to see that as it reminded me of the One X and Nexus 4, I hated both for that reason..

Screen only making up 26% of total usage? Something seems off, have you investigated for unnecessary wake-locks? Mediaserver is taking up way too much battery

indeed normally the screen uses a much higher percentage.

Saw that. Not sure why the media server would show up like that. I've just managed to get the device to die on me so I will charge it up and see what it's like tomorrow. I installed BBS also to track wakelocks.

The iphone's "usage time" is not the same as the screen on time of android. The iPhone logs usage time anytime it does anything, like synching and such, weather the screen is on or not. Big difference. Not hating on anything, they are just different measurements

But doesn't this method make those statistics a bit fake ? Never heard that iOS does it this way.

they don't care about true and reliable statistics! marketing is everything! a phone that lasts 20 hours of usage is better than a phone that does only 8, isn't?!

remember when they introduced copy, cut & paste in iOS3? revolutionary! the best phone and os around! everyone believed! that's marketing. my old sony ericsson phone from 2003 was capable of copy&paste, but they didn't shout it loud, because it seemed "natural" for them.

Ah yes. Apple is the master of presenting old things as new and revolutionary, things that has been in use for ages, they invented so many things like video calls, instant messaging, folders etc. Putting sarcasm aside, they have amazing marketing division - it's often false marketing, but its results are amazing ( then again, most companies lie to us, so it's not just Apple )

Since I rarely use more than 1,5 hours screen on time a day - I'll be more than happy if my phone lasts 48 hours, and from all the reviews it seems that with such usage - it will.

Not sure I agree, it really depends on the device, for instance although I use my arc s more than my wife uses here iphone 4s here phone is out of juice faster. while it may or may not be the case that iOS is better in power management (and if it was ever the case if it is still today). the size of battery and the power consumption of the h/w is at least as important
