First trial. Battery worse than 6.1.2.. But need to observe for few more days for more accurate info..

62% usage 2 hours and 22 minutes, first trial results. Will post up screen shot soon.

BTW, with 3G and WiFi on. Location services off.

6.1.3 can be skipped. Nothing major here.

Such as? I didn't find anything interesting though..

By the way.. It seems battery life is slightly better after a few charges compared to the 6.1.2 (3G and Cellular data - OFF , WiFi - ON, Location services - OFF)

What version? 6.1.3?

Have u guys did a full cycle recharge? e.g drain the battery to 0% and charge it to 100% without unplugging? Plus, I noticed that the more you charge, the better your battery life is..

Don't drain the battery till 0% that often. That would kill the battery charge cycle.

According to Apple, we should always keep it charged, only drain to 0% then charge up to 100% for a full cycle recharge once a month.

Try after a few charge later and make a verdict. I've experienced worse battery life at first, but after few charges, it's better than 6.1.2

Plus have you guys noticed, I used to get an delay when WiFi password is wrong. Now it's almost instant.. That's a plus point. Loving this 6.1.3 already..

By the way, the I can see better things in the next iOS update. But the thing is, when can we get a perfect version? Perhaps there is no perfect version.

At least the battery drain problem is gone at the moment. If on WiFi only, the iPhone 5 can last a day.

The one by Kingsoft seems to get a lot of good ratings. Plus it's FREE. You should try that.

Post a screenshot of your battery usage.

Can you post one with a full charge without plugging in? It's easier to compare..

Mine was alright. 6.1.3 nothing major, but the thing is the battery seems to be slightly better compared to 6.1.2, well I guess it all depends on the settings too, I had mine 3G off at all times, Location services off at all times, iCloud on Contacts and notes, Mail fetch -> manual.

I'm on DiGi Prepaid, since the internet speed is capped at 384kbps anyways, so there's really no point for me to turn on the 3G.

Plus, I have WiFi at home and office, and I only use Whatsapp and do some email checking while I'm on the run, EDGE is good enough for me..

I work in the city area, so yeah, burger king, KFC, Japanese restaurants, cafes, you name it, almost everywhere has WiFi these days.. So I don't need any data plan. I understand there's a lot of people that think that it's pointless to get iPhone 5 if you don't subscribe to any postpaid data, but yeah, that's how I use my iPhone.

Yeap, true. It isn't the same result for all, your environment plays a factor, e.g tower signal strength, the weather etc. etc.. And besides, the apps you use/installed plays a factor too. For example I don't game on my iPhone 5 so my battery tend to last longer than those people that game on their iPhone.

Oh and about the location services, I only turn on if I really need it. I don't like sharing where I was at or where I will be! haha.. No offense really, we have different lifestyle, surely.
