The iPod Touch Batteries can be replaced|
iPod Touch batteries can be replaced, even if Apple designed them not to be!
Apple has engineered several of their iPod models with the express intent that they never be repaired. When you open them up, parts that could easily be damaged (and therefore compel additional repair) are high temperature soldered down to deliberately make a simple repair impossible.
The iPod Touch and iPod Nano models are built with the intent that the battery, and the headphone jack will not be replaced.... but I can do most of these repairs anyway!
So it has to be a real point of consternation to Apple that there are clever people like me who have the soldering skills to work around their obstacles and take care of these things.
If you read my battery overview you may have an idea about how to properly charge the Lithium-ion battery that's in iPods.
If you haven't read it, here's the summary....
Lithium-ion / Lithium Polymer batteries reach 100% of their capacity in 90 minutes of charging. Every minute after that incrementally and additively ruins the battery's ability to hold a charge at all. The damage from charging it longer than 90 minutes, called overcharging, is cumulative. The heat that develops in the battery when additional current is 'pushed' into it un-binds the battery's chemistry. Charging it for 3 1/2 hours adds two hours over overcharging to the battery. Charge it for 8 hours (all night) and you will add 6 1/2 hours more of over charging to it.
Over charge it often enough and you will unbind the battery chemistry completely making it unable to hold much of a charge at all.
Since very people know this about Lithium batteries, they tend to use them as though they were the older Nickel-Cadmium (Ni-Cad) batteries where it was beneficial to completely discharge and then recharge them. Lithium batteries have the longest life when you discharge them down to 20% still charged and recharge them back up to 90% full.
Knowing this now, if you have overcharged your iPod battery continually.. you know the "charge it overnight so it's good and ready for the next day" behavior, it may be time to replace your iPod battery
The battery in the Touch models is thermal glued to a sub-assembly and then soldered in. Again, there is zero expectation on Apple's part, that it would ever be replaced. To remove the old battery means desoldering it. Lucky for me, I've had a relationship with Mr. Weller since High School and have been fixing things with a soldering pencil since then.
The 1st Gen Touch has extremely short leads, and those are soldered to the logic board directly. I've perfected a way to replace the battery.
The Touch 2nd, 3rd and 4th Gen models use a thin ribbon connection that has its terminators soldered down to the logic board directly. It requires a really high temperature soldering pencil to desolder the connection. Apple's sub-contractor that manufactures the iPod, FoxConn uses a different solder alloy for that connection than they use anywhere else. It won't melt at a temperature lower than 910 degrees.
Repeating, most batteries need to be replaced, because they were overcharged continually, which on an accumulating basis destroys the battery's ability to ever hold a charge again at all. You should spend a moment reading the article I've written about the battery used in all iPods, cell phones, laptops and cameras and how it needs to be charged. Then let your friends know this too. Read it here:
The tables below show what the battery replacement costs for each model Touch. If the Touch is here for some other reason, add $23 to that other repair for the battery replacement.
Here is an interesting case that shows the degree of intensity I exhibit at my work on hard drive based iPods
This is my most difficult iPod Touch case ever.
