I ordered mine on the day the iPt 6th gen was announced and received it on Friday last week. I did the usual, turned it on, went through all that start up hoopla on the screen then went on to restore a back up from my previous gen iPt which is still running iOS 7.1.2, and it seemed to have restored everything just fine until I noticed that the battery seems to drain faster even on standby. I was only able to make the battery last for about close to 2 days while performing light usage. I wasn't gaming, listening to music, just checking Twitter from time to time (max about 1 min use before it goes back to sleep). I turned off background refresh afterwards and after charging it Sunday evening - Monday morning yesterday, I still have a slit of a percentage left, again after what I consider light to moderate usage. On the old iPt 5 I would've been easily able to make the battery last for a few more days, like around 5-7. If I absolutely don't touch it it can even reach 10 days while still retaining a bit of charge. But this 6th gen has me a bit worried as I dunno if the A8/M8 is eating up the battery a lot faster even though it's supposed to be more battery efficient. I will restore the iPt 6 to factory settings and do some more testing, while restoring my backup to the prev gen for now.
What are your guys' battery life like if you leave it on standby?
