A way to restore and maximize iPod battery life System
I use my iPod every day for two to three hours on my way to and from work. A while ago, I was very frustrated because I believed I had to pay for a battery replacement on my second generation iPod. As it turns out, I am still using the same iPod, but last week my battery life was down to 1.5 hours again. When I came home, I started to recharge the battery and it finished after only three-fourths of an hour. Normally it should take three or four hours.

After some experimentation, I managed to restore my iPod's battery life. I've created an iPod - restore and maximize battery life how-to to help others who may have similar iPod battery life issues. I don't believe that my way of doing this is anything unique -- if you do a search on the web, you will find info that indicates that others have reached the same conclusions as I have. My how-to is based on the use of the iPod Updater from Apple, and a method to keep the iPod hard disk free from fragmentation.

I also wanted to make this easy for all levels of users, so I used a lot of screen shots and detailed instructions. Please let me know if anything is not easy to follow.

A way to restore and maximize iPod battery life
Authored by: tumbler on Nov 22, '04 02:26:12PM

Has anyone tried a similar restore procedure on the laptop batteries? My 1Ghz Powerbook is not getting about 40 minutes on a full charge (yeah, it's embarassing). I attribute this to long periods of remaining plugged in and not exercising the battery. Does anyone knows of a way to put some life back into my battery without purchasing a new one?

A way to restore and maximize iPod battery life
Authored by: raider on Nov 22, '04 03:32:49PM
Lithium Ion batteries do not need to be "exercised". In fact, they will last the longest if you try to keep them above 50% charge.

The "drain all the way" tip for extending the life of the batterry in the Apple Laptops has nothing to do with the actual battery capacity, but rather what the laptop *thinks* is the current capacity. The laptop can shut down the computer *thinking* it is out of battery because it's calibration has gotten out of whack with lots of calculations on "remaining" charge and "time to charge" and stuff. So the full discharge / full charge type cycle, on the modern Apple laptops, simply lets the laptop "relearn" the battery capacity.

Lithium Ion batteries are great in that they have absolutely no memory effect. They cannot be damaged by a billion charge cycles. But Lithium Ion batteries suck because they have to contain complicated circutry to preven over charge (as they will catch fire if over charged) and they start to lose capacity THE INSTANT they roll of the production line. (Always good to buy a battery that hasn't been sitting on store shelves for half a year).

Here is some more info:

The iPod battery FAQ

There are links to lots of battery information sites under the question:
Q: What is the best way to handle charging/discharging/storage of lithium ion batteries?

Btw, iPods have Li-Polymer batteries!

You can always try the old drain and recharge method. Also, zap your pram.

How old is your battery. after a couple years, 40 minutes is all you'll get.

I wouldn't say that the outlook for battery life is all that dire. I have a 3 year old Powerbook 667Mhz, and I still get about 2 hours, give or take 45 minutes depending on what I'm doing. I've been impressed with how well my battery has held up.

On the other hand, my 1G iPod is down 4 or 5 hours if I'm lucky.

A way to restore and maximize iPod battery life

I have a 2G iPod that is just over 2 years old and I still get 8 hours from the original battery. It's absolutely not true that "after 2 years about 40 minutes is all you'll get". I haven't done anything special (including the suggestions in this tip.)

Does nothing for the battery ....
Authored by: tsaar on Nov 22, '04 02:53:02PM

My second generation iPod is also not lasting as long as it should.
I cycle to work in about 30-40-35 minutes (depending on windforce and alcohol intake on the evening before) and after four days I need a recharge.
Yeah it's on shuffle and I keep skipping songs I don't want to hear, but still it's not very good anymore.

So I will give this a try, it seems to make sense.

But i must object somewhat to the title of this hint, as it suggests you can actually do something 'restore the battery'.

Imho it should read something like
"defragment your iPod's harddrive to make the most of dwindling battery capacity"

Doei,

That is what you get for the dangerous habit of listening to music while cycling. ;)

A way to restore and maximize iPod battery life

This seems like a lot of trouble to go to for very little effect on the battery.

With a new battery costing only $30, what is your time worth? I have not used any of these techniques and I get nice long run times out of my 1500 mAh repalcemtn battery in my 1g 5GB iPod, whose battery stopped holding a full charge after nearly three years -- reasonable battery life IMHO.

Reset your iPod instead
Authored by: cilly on Nov 23, '04 03:33:05AM

There is no need to run software restore.

There are two other possibility:

a) let your iPod completely drain

b) in diagnostic mode, do a full reset

Make sure to fully recharge the battery after either one of the above steps.

A way to restore and maximize iPod battery life
Authored by: paalb on Nov 23, '04 04:38:27PM

If you experience the same thing as I have now several times, I can guarantee you that to drain the battery completely will not help. Your iPod gets completely drained on the bus home and shuts down. When you come home you try to recharge, but the next day it shuts down again after being totally drained again after something more than an hour.

If you run the iPod update your battery is up and running again, for many hours. And if you minimize fragmentation you can maximize your battery life.

The update is the real cure.

So getting more than 8 hours out of this old iPod that I was close to paying for a battery upgrade is just great. I love new gear, but I love even more to get old equipment to work many years.

My solution was to just "restore" my ipod from the updater, then sync my library back up.
Working about 2x better now.

A way to restore and maximize iPod battery life
Authored by: MVasilakis on Nov 23, '04 04:42:56PM

Cool idea thanks. I used DW to fix the directory... (No problems found but it did optimize the directory)
Then I got to thinking why not defrag the whole drive so I used TTP4 to defrag. It must have had quite a bit of fragmentation on it because it took 2 hours to optimize.

(I was too lazy to do the whole erase drive and re-install all the music)

I dont know if this helped battery life yet... though the premise seems to be valid. I sure feel better after doing it :)

(iPod is 2+ years old and my battery life is/was aboout 4-5 hrs)

Technical short version
Authored by: paalb on Nov 30, '04 01:27:53PM

I have got input from some visitors to my web pages that wanted a more technical short version. I have added the following to my HOWTO:

So why do we do this?

Here is the scenario: One day you realize that your iPod has got a playing time thats only one or two hours. You believe that not so far ago this was no problem. You try to recharge the battery and it only charges for maybe one hour.

1. I believe there is something wrong in the OS, that makes charging of the battery go wrong. Thats why I use the updater to reset the OS.
Using the updater to reset is also the first step in defragmentation.
2. The defragmentation I believe is useful to do every time you decide to remove some music and replace that with some other music. Then you get minimal movement of disk heads
3. The third thing is not to stress your filesystem and OS by filling it up 100%, which I believe might be the reason for the corruption of the OS in the first place.
4. We use the Disk Utility to check that the filesystem is O.K.

I was having problems with my iPod battery holding a charge and when I took it to Apple it was going to cost about half the price of just buying a new iPod. My friend told me about this website called www.laptopsforless.com and it was great. I got a new iPod battery and now my iPod works like it did out of the box. I would recommend the site if your iPod battery is failing.
