I purchased an iPod Touch 6 last week and found the battery life to be less than stellar. It's discharging at a rapid rate when I download anything, streaming, or playing games. I would download several apps and some music and it would drop a couple percentages in a few minutes. It seems to be more frugal with battery life when playing music only. EDIT: I monitored the battery life and it drops 1% every 20 seconds when downloading an audible book. The download took about 4 minutes, so by the time it was done downloading I had 44% where I started at 58%.
I've tried discharging completely. I have also charged the battery about 10 times thus far. I reset everything and started new. My screen brightness is only 30%. I disabled location services, turned off mail push, turned off fitness tracking, bluetooth, wireless. The end result is the battery is still discharging quicker than I would like. I have not gotten more than 7 hours with frugal use.
I wished they would have made this IPT6 thicker by about 2 mm, which would have allowed for a higher capacity lithium battery, and leads to a greater user experience by not having to recharge so much. I like the iPod a great deal, but the battery life is making it difficult for me to enjoy the ownership experience knowing that I am limited by the amount of time I can spend with this device before charging it. I have an iPad Air and iPod Classic which both have battery life that I don't need to worry about.
So my question is whether this would be different if I exchange for a new iPod Touch? It might be difficult in my case because I have a custom engraving.
