IPod touch 5 battery problem...

Hello everyone,

I bought a 32GB iPod touch for my wife in September 2014. From the first use we noticed a problem. After warning of 20% of battery, the iPod stopped almost automatically. In addition a recharging only took half an hour, instead of the four hours listed on the site.

We then contacted Apple in early January. the operator advised me to make a restore of the iPod. Without any success. After a second call, Apple told me that he had to send it back. Five days later, I received a new device.

And there again ... The iPod battery shows 20% and turns off too quickly. New fast recharge (about 90 minutes).

From there, I began to closely check our usage. The other day my wife sees the alarm 20% on its screen, performs a Facetime audio only about ten minutes, listening to 30 minutes of music she sent on a bluetooth speaker. No alarm 10%, nor 5% like on the iPad. The iPod turns off.

When restarting after 3 minutes charging via USB, I note that the battery is already charged to more than one quarter. After half an hour, it is recharged to more than a half.

I look into battery settings. It indicates 6h30min of usage and 2j23h on standby. It is crazy, an iPod battery can not last 6:30 it is not enough!

Would I received a second failed device?

So, I do not know what to do, I wanted to buy an iPod touch myself but as my wife's one seems to malfunctune...

I contacted Apple Support a third time. The counselor did not seem to be a iPod specialist. She advised me to search the forums but I have also been told we could send it back once again. What do you think? What should be the performance of an iPod touch battery material?

Thanks in advance guys.
