I replaced my 2gb microsd card with a 16gb card..It 'seems' to me the battery is draining a lot quicker..That was the only change, other than extremely low temps..
The question is 'how many watts do the cards draw and is there a big difference in the 2gb to 16gb to 32gb..
thanks
I'm too interested in this.
Find a spec sheet from the manufacturer. It will tell you exactly what the draw is. I'm fairly certain that a sdcard, when not actively reading or writing should be in a sleep mode, drawing under 1mw. Since it should be in that state most of the time in a phone, I'd be really surprised to see a card make a measurable difference in battery life.
The low temperature is more likely to be the real culprit. Batteries do NOT like the cold.
In any case, the true test is to switch back to your old card and see what happens.
The microsd card from SanDisk that came stock with my G2 stopped working today. Android says it is damaged and I get "semaphore timeout" issues when I put it into my computer. This really sucks since the card had all my backups and photos and some apps.
To avoid this in the future, I got a replacement card (name-brand) and I was wondering if my phone caused the damage.
I am using CM7 oc'ed to 1113MHz. I also have an extended battery (http://bit.ly/kj6f9r) and I've noticed that the phone gets pretty hot while charging or with really prolonged use. Could the heat have toasted my sd card?
Also, is a setcpu profile depending on temp a good idea? I'm not sure what temp it is actually measuring.
Thanks
Don't think heat is really the problem. Sandisk's official specs say their cards are good to 185 degrees F. That's not too far from boiling. And more than hot enough to burn your hand, so thats hotter than your phone is getting, even inside the casing.

And flash memory is pretty durable. These guys dunked them in coffee and cola, ran over with a skateboard, and other stuff. The result, they still worked.

Memory just fails on its own sometimes. The brand names tend to have better mean failure rates. But remember, that's just an average. They can really fail at any time. A better brand card is just less likely to fail early.
Also, I know that overclocking to 1 GHz is possible without over-volting. So I doubt the CPU clocking you mention requires much over-volting, either. And not much over-volting means not much extra heat. Lots of people on here OC to much higher clock speeds, and apparently do fine with SD card life.

Samsung Galaxy Young Battery Reference + Guide
All you need to know about SGY battery
Battery Info:
Standard battery:
Li-Ion 1200 mAh
Technology:
Lithium Ion
Stand-By:
Up to 850 h (2G) / Up to 540 h (3G)
Talk Time:
Up to 17 h (2G) / Up to 6 h 20 min (3G)Li-Ion Battery
A lithium-ion battery (sometimes Li-ion battery or LIB) is a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Chemistry, performance, cost, and safety characteristics vary across LIB types. Unlike lithium primary batteries (which are disposable), lithium-ion electrochemical cells use an intercalated lithium compound as the electrode material instead of metallic lithium.Battery Cycle
Battery Cycle Life is defined as the number of complete charge - discharge cycles a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. Key factors affecting cycle life are time t and the number N of charge-discharge cycles completed. Battery Life
Battery Life is the elapsed time before a battery becomes unusable whether it is in active use or inactive. There are two key factors influencing calendar life, namely temperature and timeHow to prolong battery life?
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last.If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Avoiding full charge has benefits, and some manufacturers set the charge threshold lower on purpose to prolong battery life.Ideal battery Charge Time3.7 V Li-ion Battery
120 mins - 65%
135 mins - 76%
150 mins - 82%
165 mins - 87%
180 mins - 100%
Simple Guidelines for Charging Lithium-based Batteries
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger so turn off your phone when you are charging the battery.
Charge at a moderate temperature. Do not charge below freezing. Do not charge your phone in your fridge
Lithium-ion does not need to be fully charged; a partial charge is better.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
Battery Calibration
What is battery calibration?
Battery calibration is a complete discharge and charge cycle of a battery that helps the batteries charge and discharge performance.Any methods of doing that?
Yes, aside from full charge and discharge, you can delete batterystats.bin which is available on ClockWorkMod recovery under Advanced and Debugging.Deleting batterystats.bin, cool! -no it's not!
Deleting batterystats.bin is a Myth! Read this article from Google+ by one of Android engineers Google+ ArticleSources:

Storage - MicroSD's, SDHC and more!
All you need to know about storage, finding the right sd card and more! Secure Digital Card (SD Card)
Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. The SD technology is used by more than 400 brands across dozens of product categories and more than 8,000 models.
SD comprises several families of cards: the original, Standard-Capacity (SDSC) card, a High-Capacity (SDHC) card family, an eXtended-Capacity (SDXC) card family, and the SDIO family with input/output functions rather than just data storage.Types of SD CardsCompatible with Samsung Galaxy YoungStandard SD or SDSC Card (the one came with your phone from Samsung)
The standard SD card measures 24 mm by 32 mm by 2.1 mm and has a maximum storage capacity up to 2 GB. The compact design makes it ideal for portable storage of photos, songs and video files, replacing the need for bulky tapes and discs
SDHC
The Secure Digital High Capacity (SDHC) format, defined in Version 2.0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility.
SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in Version 2.0 (see below), and the fact that SDHC cards are shipped preformatted with the FAT32 file system.NOT Compatible with Samsung Galaxy YoungSDXC
The Secure Digital Extended Capacity (SDXC) format supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification.SDIO
A SDIO (Secure Digital Input Output) card is an extension of the SD specification to cover I/O functions. Host devices that support SDIO (typically PDAs like the Palm Treo, but occasionally laptops or mobile phones) can use the SD slot to support GPS receivers, modems, barcode readers, FM radio tuners, TV tuners, RFID readers, digital cameras, and interfaces to Wi-Fi, Bluetooth, Ethernet, and IrDA. Many other SDIO devices have been proposed, but it is now more common for I/O devices to connect using the USB interface.
SDIO cards support most of the memory commands of SD cards. SDIO cards can be structured as 8 logical cards, although currently, the typical way that an SDIO card uses this capability is to structure itself as one I/O card and one memory card.SD Card ClassesWhat is the SD Speed Class?
The SD Association has established standards that rate the minimum data transfer in SD, SDHC, SDXC, SDHC UHS-I and SDXC UHS-I memory cards and devices. The speed rates were established based on the needs of movie and video companies because video recording requires certain writing speeds when recording the data onto a memory card. The SD Speed Class and UHS Speed Class standardized the specification for both memory cards and devices in order to guarantee minimum writing speeds and deliver the best performance.Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD cards. The class number guarantees a minimum write speed as a multiple of 8 Mbit/s (1 MB/s). The SDA defines several speed class ratings, but manufacturers may claim conformance to those ratings without independent verification.These are the ratings of all currently available cards:
Class 2 - 2 MB/s
Class 4 - 4 MB/s
Class 6 - 6 MB/s
Class 10 - 10 MB/sWhat are the applications for Speed Class?
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, digital still camera (DSC) consecutive photo shooting
Class 6: Mega-pixel DSC consecutive photo shooting, professional video camera
Class 10: Full HD video recording, HD still picture consecutive shooting
SD Card PartitioningWhat is SD partitioning?
SD Partitioning is the act of dividing a SD Card into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks. Partitions are also termed "slices" for operating systems based on BSD, Solaris or GNU Hurd. A partition editor software program can be used to create, resize, delete, and manipulate these partitions on the hard disk.SD Card Partitioning Guide - XDA Wiki
