I'm really wondering what is going on with these folks experiencing battery issues. My 920 seemed to indicate a low battery for a couple days after I bought it, and I was concerned, but then lo and behold it seemed to automagically become very good and has been ever since. I get at least 30% better battery life than my wife's iphone 4S easy.
Today was typical for me. Couple calls, web browsing here and there, facebooking and checking the news and email in my spare time during the work day. I was in a text conversation for going on two hours with occasional replies. If one used a smartphone at work more than I do, one probably won't have a job much longer lol. I took it off its charger this morning at 730am. I got home at 630pm and still had 50% battery life remaining... I know for certain because my wife has been bitter about her iphone battery dying at work (she's the one I'm texting all the time), so I've been teasing her the last couple days by calling out how much charge my battery has left. Her: ::: plugging in::: Me: :::quick check of battery status in settings::: "50 percent." Her: "You suck." We had just gotten home from work and picked up a pizza from Pizza Hut which I ordered on the way using the Pizza Hut app (unfortunately the only app to order pizza on at this point... but more will come, and it was quick and simple).
I haven't gone all out to save battery either. I just did the obvious. I turned NFC off as nothing uses it. Wifi and Bluetooth stay on all day, and my truck has Bluetooth. I listen to my music every day in the truck via the audio jack. My commute to and from work is about an hour total. I disabled a few apps that I don't need running in the background ever. I have my screen brightness set to medium rather than auto... I don't use the phone outside much at all.
I have a start screen filled with live tiles. Weather, me, local friends, family, close friends groups, groupon, cnn, livescape and more. I have 3 email accounts and I set two of them to check less frequently - really just to avoid the constant dinging.
11 hours using 50% of the battery in a typical work day's worth of poking around, browsing while in line at starbucks, texting throughout the day, couple calls, music and all the regular background activity on the phone is pretty damn good if you ask me. For the record, my wife's iPhone 4S's battery was dead by the time we got home.
Now if I play certain processor heavy games, those will chew up the battery. That's to be expected and that's the case on every phone.
Hope this guy enjoys his note. Those things are hilarious. I would have thought they were parodies of the continuing increase in phone size if I didn't know they were real phones.
