Yea, I'm actually a bit dissapointed with the battery life. I've read countless reviews stating that the Infuse delivers good battery life, however I'm not experiencing it. I'm thinking maybe since all the other smartphones have crappy battery life, that in general, the standard for battery life on smartphones has been lowered. My bro has the Atrix, and he too is extremely dissapointed with the battery.
What phone are you coming from? Ive had iphone, palm pre, hero, now evo. So I'm used to bad battery life. I do wish there was a standard test app for battery life. Like quadrant for processors.
In my experience if u can get 15 hours of lite use then you are doing good.
I'm sure an extended battery will be out soon. Since the phone is so thin adding a few mm's to it won't be a huge deal for the people that can't charge during the day.
Before the infuse, I had an iphone 3G S and then the iphone 4. Honestly, I forgot how the battery life was on my 3G S, but I would definitly say that thus far my iphone 4's battery life exceeds the infuses.
That being said, I think the smartphone manufacturers should start focusing on developing better batteries instead of making the phones more powerful.
I lol'd at this thread it's either Samsung or all android phones, but going all the way back to the Moment I owned to the Evo to the Captivate the battery has always died faster than my iPhones. However, the battery life is not hopeless if you avoid wifi, 4g, gps, live wallpapers, high brightness, web browsing, playing games and watching videos.
Well, I might not be getting the best battery life, but turning off the lockscreen Widgets has made a big difference. I still currently have a call blocker, cpu/battery monitor and juicedefender running in the background and have been pretty much all day since I unplugged the phone around noon. And I still have 83% battery life left. The phone hasn't been used heavily today, but yesterday, in a few hours, I lost over half the battery while in sleep mode. So at least for me, I found a major drain, which was widgetlocker.
Its not perfect, but im happy. It is a great phone and I would have been disappointed to have to give it up because of a weak battery.
