battery meter down to 20% in 13 hours

Compared to me, thats pretty good. I'm dead after 8 hours of my normal use, if I don't plug in at all during that time.

Just a few phone calls, some texting, a lot of facebook/twitter checking and some web browsing.

 

I am lucky to make it six hours with what I consider normal use. GTalk, a few phone calls, SMS, some internet browsing. I have one complaint with this phone and it is the battery, I just carry my charger everywhere.

 

If you have some extra coin, get another battery and a battery charger. It's unbelievable how convenient it can be to just pop in another battery. I'm not even a "power user" that can usually go 12-14 hours before I even think about it, but it's very nice to never be plugged in.

 

My mileage is decent at best honestly but it's really hard to judge. when I was still in school before the summer I wasn't using my phone as heavily(except during lunch and sneaking it during class lol) both in the morning and afternoon I'd use it heavily and could get like 15 hours using both system panel app and screebl. but now since it's the summer time and I've rooted, not having a job I have more time on my hands so I've been using my phone quite a bit more. I am absolutely OBSESSIVE about my battery life, so much it's hard to fully enjoy it.

but to answer the question better, I was running the build you were on for a bit and I would get like 4 hours and something minutes on what I can assume is "heavy usage" taking a few breaks putting it down and constantly browsing the we(cuz I'm so addicted to the stupid thing)
but on what I can call "moderate-to heavy use" I am usually lucky to get more than 8 hours and something minutes, but if I really try to use it in moderation I could get a decent 13 hours.
sorry to ramble so much, I just ocd crazy with this stuff. lately I've been using the 900mhz lv p3 kernel underclocked slightly with some setcpu profiles.
Now I'm on the newer build, frg22 with the 1000ghz p3 kernels also using profiles, I'll see how it goes. it's hard for me to give a good measure as well lol

 

and if your using it heavily I'd say that's great usage. I'd more than appreciate to get at least 13 hours a day. :/

 

I am around 8 hours with normal use and about 3 hours with heavy use on Saphire 1.0 with there stock kernel. I would love to get 12 hours of normals use. Oh well, I have plenty of chargers.

 

4 hours of use heavy or not most of drain is the screen. Over night with the screen off I might lose about 10%. So on standby it will last days I think but using internet or whatever I get about 4 hours.

 

I can get about 10 hours in a day with moderate usage. Web browsing, texting, a few games, waking phone up often to check widgets, an hour or so of phone calls.

Best I have ever gotten is about 28 hours. I heavily make use of setCPU profiles, and am running a low voltage kernel.

 

i can probably get 8+ hours with moderate use. texting, browser, and facebook. thats when im at work. but i also try and use it wisely because im afraid itll die

 

i get about 20 hours with about 45 minutes of talk, 200 texts, 30 minutes of browsing and then lots of time just goofing off on it. Display takes up most of it. I run BB .4 with 1.1 ULV Chevy kernel
