At the Apple iPhone 4S conference, Apple introduced the phone to the world by saying: The same shell as the iPhone 4 is completely different. So, how is it "completely different" in the end?
Step 1: Configure:
-Apple-made A5 chip, 1GHz dual-core processor
-8MP rear camera (1080P video shooting) + VGA front camera
-802.11 b / g / n + Bluetooth 4.0
-LED backlit IPS TFT LCD ReTIna display with 640 x 960 resolution
-Quad-band GSM / GPRS / EDGE + dual-band CDMA / EV-DO Rev support
Step 2: Shape
The iPhone 4S continues to use the classic shape design of the iPhone 4, and Apple also fixed the issue of the "antenna door" that caused the hot debate that year. Does this mean that we will not get a free Bummer case this year?
The SIM card slot is back! Now that the iPhone 4S is called a global mobile phone, it will support both GSM and CDMA networks. In other words, no matter which operator you buy the iPhone 4S from, the SIM card slot will always be ready for you to insert a GSM or CDMA card.
Step 3: Start disassembly
We saw Pentalobe screws again. I thought I would see some new parts this year, but it seems that our old friends still like to stay on the iPhone 4S.
After using a Pentalobe screwdriver to beat the drums for a while, the screws were successfully removed-just as I had tried it on the iPhone 4.
Step 4: Shell
We continue to use the method of dismantling the iPhone 4. Use the same steps to remove the glass back cover of the iPhone 4S, and remove the battery, and then we once again saw the words "authorized service providers" written on the label.
Digression-At this time Siri seems to be saying: I must ask you to stop your work, iFixit. Because you do not have any authorization qualifications. iFixit's response is: this label is too naive, no matter before or now, it can't stop us.
Step 5: Battery
We finally saw this battery highly praised by Apple, let us take a closer look. Oh, its WHr (waist to hip ratio) seems to be larger than the iPhone 4 battery.
Do you want to know whether this battery can be installed in the iPhone 4 body? Unfortunately, the shape of the connector used in this battery is different from the iPhone 4, so the battery and iPhone 4 should not work of.
According to the figures at the conference, we know that the iPhone 4S battery supports 8 hours of 3G network talk time, 14 hours of 2G GSM network talk time, and 200 hours of standby time. Compared to the iPhone 4, the talk time on the 3G network has increased, the talk time on the 2G network has not changed, and the standby time has been reduced by 100 hours.
Step 6: Motherboard
With the help of an iPhone-specific disassembly tool, iFixit removed the motherboard of the iPhone 4S. This "L" -shaped motherboard looks very similar to the CDMA version of the iPhone 4 motherboard in the United States. Where should we start?
Digression-At this time it seems to hear Siri's voice again: please let me go. It seems that it can still talk after no battery, maybe it is really everywhere.
Did you notice the white triangle sticker on the right side of the motherboard? This is a liquid indicator.
