Yep, def.
Do not expect your iPod to run for more than 10 hours if your running games and editing photos.
Mine is brand new and just got it's battery checked and it'll last me 5-10 hours of gaming depending on what games I play, sometimes even less...
When not gaming and doing regular web surfing, listening to music, stock checking, light gaming, note taking, etc. I can go up to 2 or 3 days without charging it.
Some tips:
-Use auto brightness, it automatically adjusts your brightness to the correct amount depending on how dim or light it is. (Turn that on, and the brightness toggle at about 60%) The brightness toggle is the maximum brightness it can achieve.
-If you don't need them or you don't have wifi 24 hours a day, I see notifications as a waste of battery life, turn them off.
-Wi-Fi, when not using it turn if off, it only takes seconds and it drains your battery.
-Bluetooth, with BlueTooth on you won't even get 5 hours of regular use, I consider it the biggest battery hogger out there.
-When listening to music, try to not fast forward or go back on a song because I heard this drains your battery a bit.
-Clear your multi-task bar periodically, I usually clear it every time I remember too because I'll usually have 4 or 5 apps on it. This will help save battery as well.
Hope I helped.
