Just one day before Apple's iPhone 4S hits store, the team from iFixit disassembled the iPhone 4S and took a peek inside the new smartphone and posted photos.
 
The results suggest that the iPhone 4S is not so good as Apple claimed and we thought earlier. The iPhone 4S features A5 dual-core processor, 8-MP camera, up to 64 GB storage capability, iOS 5 and iCloud.
 
Here are some interesting things you need to know about iPhone 4S before snagging one.

512 MB RAM
 
Many people believed that iPhone 4S has 1 GB RAM. Unfortunately, iFixit revealed that iPhone 4S only has a 512 MB of DDR2 RAM.
 
Markings on the A5 chip (E4E4) show the processor has two 2 Gb LPDDR2 dies (4 gigabits is equivalent to half a gigabyte, or 512MB). Both Apple's iPad 2 and iPhone 4 feature 512MB RAM.

100 Hours of Lost Standby Time
 
iFixit said iPhone 4S has an extra .05 WHrs in the battery over the iPhone 4. iPhone 4S' battery offers 8 hours talk time on 3G, up to 14 hours talk time on 2G, and up to 200 hours standby time. This means iPhone 4S offers 100 hours less standby time.
 
Analysts said this is because iPhone 4S has a more powerful processor and some upgraded hardware that may consume more power, according to the blog Bits. 
 
Siri cannot work on iPhone 4
 
The details about iPhone 4S reveal that Apple's new personal assistant Siri only work with A5 chip. This means Siri will not work on previous iPhone, but iPad 2, which sports A5 chip, can easily integrate Siri with a software upgrade.
