Best SD Card for Overall Android Battery Life

So after some searching and finding some good info, I thought it would be pertinent to have a singular thread where we can compare Android battery life with various sd cards. So to start, I will post my stats:
winmo rom - Omega v. 13.3
Android rom - Darkstone HD2 Froyo V. 2.1
Stock 16GB SD card
I get about 8-10 hours with light to moderate usage. I see around 200 mA draw pretty consistently. :/ I have seen other users who have had significant increases in battery life with different SD cards... sooooo, who's up?

It's not the microSD card. That is a bit of false information that someone spread like wildfire.
Try out different Roms with the latest kernels that correct for the lights problems.
I use the Elegancia rom as a base and Mdeejay's Froyo Sense as my Android rom.

You can update the hastarin kernel here:

Instructions for updating the kernel are in the download. Super easy.
Oh yeah, SetCPU is your friend. I'm using the same settings as Hastarin:
* Type | Priority | Min | Max | Governor
* Main | n/a | 245 | 1113 | interactive (set on boot)
* Temp > 50C | 100 | 245 | 768 | conservative
* Charging/Full | 95 | 768 | 1113 | interactive
* Screen Off | 60 | 245 | 245 | powersave
* Battery < 25% | 50 | 245 | 576 | conservative
* Battery < 50% | 30 | 245 | 768 | interactive
* Battery < 90% | 0 | 245 | 1036 | interactive

Hi,
1.Try to use lite winmo rom, recommend: ozDroid.
2.after boot winmo do not load any app, just click android boot loader.
3.Try to push key button to get light up while loading harlet.( after screen change resolution, the key light with disappear, this is normal. )
4.Don't install anything at first ,don't sign in google, upload & install currentwidget.apk to your device , add to screen and see you log file.
At this step,you should see about 4-15ma.
if you found 60ma draining: you have problem in power management or sd-card.
we have active forum about sleep battery draining here, check it out.

Wait, something was written on the internet that isn't true? That isn't possible! lol Thanks for the info! I am going to go search for an awesome Desire based ROM... Any suggestions?

I'd suggest updating the kernel files even before adding it to your SD card (that's what I did today when I had to redo my install.)
You can backup your apps and settings using titanium backup. I actually paid for the app. Worth every dime imo.
Gluck!

OK, so after many tests over this past weekend I think i found my preferred setup:
winmo rom - ChuckyROM Lite
Android rom - Mdeejay FroYo Sense v. 1.1 Clean
Radio - 2.14.50.04
Factory 16 GB SD card
Today I unplugged the charger at 7:30 am. Light to moderate use of the phone including about 20 texts, a few calls averaging 4 minutes each, and about 45 minutes of some Angry Birds play. With my previous setups, I would usually see about 300 mA of current draw even in standby, which would kill my battery in about 7-8 hours with very light use. As my phone sits now I see 4-9 mA draw in standby and after 12 hours I still have 52% battery!
This android build is the best I've used... I have had zero issues so far. Boots fast, runs fast and smooth, apps install with no issues. Just awesome!

i've used both stock and transcend 16gb class 6 cards. haven't found any difference

Not using Juice Defender anymore since wipe flash. Seems OK so far although most of the weekend was on wifi (no sleep).
This run's about to come to an end as I fire up Tunein to catch the hockey game. Love the program but its secondary function is to turn the phone into a heater.

Lots of guys posting ~1 hr/day screen times in here. On the weekend I'm right near my laptop and desktop so not much use. Most of that time is playing Let's Golf 2.
I don't use it a ton during the week either, some personal e-mail and surfing at work or during lunch, some music and maybe gaming on my 15-30 min ride/walk to work and a bit before bed. Music or streaming radio at work pretty often, but doesn't add to screen time (although Tunein burns battery like crazy and Slacker uses a good amount).
I don't have many calls but when I do it's often 1+ hrs with family. In my limited experience talk time is pretty rough on the battery too.

Anyone knows if there is a app which records the signal strength and the cell changes on 2g/3g network? I always have the strong feeling that the battery decreases much faster when having a bad signal or when moving with a car, especially with 3g (since the cell size is smaller). But i didnt find any hard facts ...

I think 1h/d of screen on time is pretty normal.
checking the time, maybe 15min of youtube, reading news and some meganoid/pew pew/poker and one or two phone calls sum up to it and I guess (based on the thread so far) that that's pretty much the average. It seems like it's also a good trade-off between usage and battery life, since the screen is what needs the most power. not that I would not use my phone just to prolong the time till the next charge (well maybe yes, but only when I'm on 10% and got 4-5h until I can charge). With my usage pattern and setup I can easily get 3days out of one charge and I'm pretty happy with it.
3d of course when not flashing any kernel or doing the weekly nandroid full backup (which I recommend^^)

Yeah I hadn't thoroughly looked at the other people's on screen time and I guess your right about the average.
I just feel its different in my case as I use my phone quite a lot throughout the day, as I don't take my laptop with me to school. I'll post my stats after this charge dies.

Oh no doubt. I sit in front of a laptop all day at work as well. If I was still in school and roaming campus all day (and the bars at night lol) I could see putting 2-4 hours on the phone every day easy.

There's another thread which says that the JVE modem helps in prolonging battery. I think I'm going to try it out as clearly the guy above has amazing stats and he's using it so might as well try it.
Here's the thread

rild chewing through battery

Currently running CM-7.0.3 on my Nexus-S but the same problem happens on stock 2.3.4 as well.
Using System Monitor I can see that Dialer Storage (/system/bin/rild) is constantly running at about 10% of CPU. This means the phone never actually goes to sleep and discharges a full battery in about 12 hours.
However, if I kill rild it restarts immediately but then behaves normally.
# ps | grep ril
radio 129 1 11304 3820 ffffffff ffff0520 S /system/bin/rild
# kill 129
# ps | grep ril
radio 1492 1 9276 2060 ffffffff afd0be2c S /system/bin/rild
So short of doing the above every time I restart my phone, what could be causing rild to go crazy?

My comments
Partial Wakelocks look clean just like every other well-running Android phone that I've owned. The heavy-handed WiFi management using the Deep Sleep app has controlled some of the EINT wakelocks, at the expense of delayed notifications. Overall run time is useable, but seems poor for a 3000mAh battery.
