My wife's iPhone 6 has had some major battery loss issues. I took it to Apple 6 months ago and they said it was normal and the battery drain could be software related. We reset the phone, restored, and did the other battery resets that were recommended. Fast forward to last night. My wife said her phone died after 2 hours today. I checked coconut battery and the stats were: Charge Cycles: 512 Current Charge: 100% Full Charge Capacity: 4XX (I can't remember now. I took a screen shot but the mouse was hiding the last 2 digits) Design Capacity: 1810 (23.9%) I wasn't sure if coconut battery was off so I installed the battery life app on her phone and it says: Capacity: 500 /1810mAh (28%) Battery Charge: 500/500mAh (100%) Clearly the battery is defective since Apple says a 300-500 charge cycle iPhone has 80% capacity. I'm going to take it in this Friday and see if they will replace it for free, but is there any other information I should bring? The phone is an iPhone 6 so it has no warranty left. I would hope they would do a courtesy replacement for us. Or perhaps I'm blowing this out of proportion and this is normal. Thoughts?
