Most of my setup can be found in my "quick faqs" linked in my sig line but overall, not many changes to the system.
I have an unlimited data plan and have my location services turned on. I have agps turned on as well. Email is set to "push" and I get my mail as it arrives on my gmail server.
Weather is set to update every three hours and I have my screen set to 60% brightness.
I am currently running hypnotics battery cab but I am going to switch to MAXX's once I get back home to my USB cable that I forgot before I left on vacation.
The only other thing that is different for me is I bought a set of EVO/Incredible (non OEM) batteries and a pocket charger from Amazon.com. The whole set was 24.99 (I linked to it a few pages back) and the batteries are 1800mAh vs our 1300 mAh. I'm currently at 36 hours and at 50% charge as we speak. However, I STILL get great battery life out of my stock battery as well.
Did I mention that I'm overclocking as well?
Yep, 729 and rock stable.
I think I'm gonn jinx myself with this but sometimes I just think I got a really good phone. I've heard of good runs vs bad runs and later runs vs. older runs, but it just seems like mine is at its peak. Lots of the problems that other people complain about, I just don't have. Also, I DO NOT and have not used Task29. And I've flashed probably 12 ROMs over the last couple of months.
My daily use is about 50 emails/day and about 20 to 50 texts. A few phone calls, regular internet use with bing and google. And a lot of Solitair and teeter when I'm bored. Some days I even fire up my S9-HD bluetooth headset and listen to music for a few hours.
One thing that also made a big difference is the type of signal I'm getting. Right now (in Charleston SC) I have a great EVDO signal everywhere. Back home (Knoxville TN) I have acrappy signal and spend a lot of time in 1x. At my house I used to have a gen 1 airave (femtocell) and got crappy battery life with it. Sprint just upgraded me to the newer Airvana which does EVDO and that made a BIG difference for me on days that I spend at my house. Without the airave I had ZERO signal in my house. Around Knoxville I see that I switch a lot between EVDO and 1x which I think makes a big difference.
For those that are having very bad battery life, is your phone switching between 1x and EV alot? That may be one reason your battery life is so low. Also, does your phone get warm? I always found that mine gets warm if it is looking for a signal - even if it shows bars.
Just thought I'd try to shed a little light.
