How long should the charge last on my ipod touch?

Maximum Battery Life
The new iPod touch can play music up to 36 hours, the new iPod nano can play up to 24 hours, the new iPod classic can play up to 36 hours, and the iPod shuffle can play up to 12 hours on a full charge at original capacity. Apple runs tests for battery life using songs encoded at 128-Kbps AAC and songs purchased from the iTunes Music Store (128-Kbps AAC). The songs are played continuously through a playlist without interruption, with backlight and equalizer off. For all iPod models, factory default settings were used except that iPod touch units were associated to a Wi-Fi network and Auto-Brightness was turned off.


Charge Cycles
A properly maintained iPod battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.


Let It Breathe
Charging your iPod, iPod nano or iPod shuffle while in certain carrying cases may generate excess heat, which can affect battery capacity. If you notice your iPod gets hot when you charge it, take it out of its case first.

# Top up the charge frequently! Charge your device often to prevent rapid erosion of the Lithium-ion battery's capacity. Never let your battery run down to zero. Your battery will fast charge for 1.5 to 2 hours to reach 80% charge and then 'top-up' charge for 2 to 4 hours more to reach 100%, so try to charge a weak battery for at least 2 hours. Lithium-ion batteries lose capacity as soon as they are manufactured but a properly maintained battery is designed to retain an average 80% of its capacity after between 400 to 500 charge cycles.
# Leaving On Charge You can leave your device on charge for as long as you want. There is a protective mechanism in all Lithium-Ion batteries that prevents 'overcharge'. i.e. don't worry about those long overnight charges.
# Recalibrate Your Battery Meter - If you charge your device regularly and also use the 'Numerical Battery' you may want to consider running down the battery once per month followed by a full charge. The battery meter tracking the battery's capacity will lose accuracy over time and this full discharge will recalibrate it. If you use the stock Apple battery icon then there's probably no need for such accuracy unless you start to get strange readings.
# Keep your iPod Touch cool! Lithium-ion battery capacity rapidly decays if exposed to high temperatures. Don't leave your device in the car. Maximum operating temperature suggested is 35° C (95° F). Don't charge when hot as this can further damage the battery's capacity. Remove any cover/skin when charging to help prevent overheating.
# Maintenance in storage - If your don't use your device regularly, make sure you complete one full charge cycle per month to slow battery degredation. This can be staggered, e.g. use 50% of battery, charge full and then use 50% again. When not in use store your device below 45° C (113° F) to prevent heat damage to the battery's capacity. Store your device with a partial (~40% best) charge.
# Stay updated - new firmware and software updates often include more battery-efficient code so update and keep current if you can.
# Manage Your Apps - conserve your current battery charge by turning off 3G, WiFi, Edge, SSH and/or Bluetooth when not in use. Other functions such as GPS & Push Email will also cause the battery to drain faster. Turn off the WiFi function 'Ask to Join Networks' as this can leech the battery. Update email manually. Use 'Airplane Mode' in areas of low coverage to prevent continuous scanning draining the battery. Turn off 'Location Services' in Settings when not in use. Hold the home button for 5 seconds to kill any applications running in the background.
# Equalizer - turn the EQ off if you don't need it.
# Backlight - Turn the brightness down as low as possible (~10-25% is good) and enable 'Auto Brightness'.
# Screen Lock - Use a short 'Auto Lock' time. Turn the screen off whenever it's not in use by a quick press of the power button.

Airplane mode is for cell phones. To shut down all cellular signals and data while on an airplane or in an area that does not allow you to have these services on.



It is not something you will have on your iPod Touch. The info provided is generic suggestions shared for both iPhone and iPod Touch. So not all tips will apply to both products. I hope this has cleared it up a bit.

You mention "use airplane mode." What is that? I searched the Manual and I got not hit.

Thank you.

Yes, it cleared. Thank you very much.
