How much can a 16gb 6+ sell? Still under warranty, thinking of selling and upgrading to 6s+ 64gb

Like the new white silicone case with the dark grey Apple logo, like the smooth feel of the case too



(6s pic from mnmllymnml)

Apple silicone case can be easily clean with wet wipe or eraser as compared to the permanent stain of tpu or leather case. One week later not a single stain even with sweats, grease etc.
The only problem with this case like all Apple accessories is bloodsucking overpriced haha

Probably not fit snugly coz the different thickness. I have the old 6+ silicone, 6 leather and this. The leather is worst when comes to wear and stain, can't even clean and way too expensive. The old 6 silicone is fine (grey) after months of use, only problem it is a fluff magnet and made worst by the colour. The updated white with dark Apple logo attract hardly any fluff and hide all the fluff if any coz it's white

Battery life span is contributed by multiple factors.

The 3 most common cause of battery life shortening are
1. Heat.[1] [3]
2. Keeping at constant high/full charge capacity. [1] [3]
3. Frequently draining the battery from 100 to 1%. [2] [3]

1. and 2. are contributed via leaving it on charger over night.
If one intend to leave it charge overnight, it is advisable to use a slower charger[2] or use a plug timer or power bank that stops once reaches 100%.
What happens when one leaves the phone connected to a charger overnight is the phone will stop charging at 100% but when it drops to 99%, it will begin charging again. Hence maintaining a full capacity charge that relatively shorten a battery life [1]. Also repeated "tap of chargers" at 99% to 100% will have less charging cycles than the charge from 49% to 50% by 3-4x. [3]

Hope it make sense

My iPhone 6s+ touch ID works flawlessly. However my iPhone 6 touch ID sometimes just can't read my fingerprint until I key in pass code.

Try cleaning up the Home button. Obviously if it's dirty, it affects the ability to read finger prints.

How about Apps for download good quality songs direct to iphone ? any recommendation ?
