iPhone 6(S)/Plus 6s Battery Issue

[wproct]

My 6s is about 2 1/2 years old and battery performance has been very good. I will normally leave my phone turned on and on silent at night and it will use 4 -5 % charge overnight. All of a sudden I went to bed one night with battery at about 98% charge and when I got up in the morning it only had about 2 % left. I charged to 100 % in less time than I expected, but ever since then I am getting only about half or less of the tiime on a recharge compared to what I would get before this happened. Does anyone have any idea why my battery performance has dropped so drastically all of a sudden? Thanks in advance for any responses.

I’d replace it. It’s definitely due for it.

I've had that happen with my 6s from time to time. Everything goes back to normal after a while, but it is strange. There is a recall on the battery for some 6s devices. You may want to check if your iPhone is eligible for a free battery replacement.

Time to replace your 6S battery. Charging quirkiness is a sign that the battery is failing, and 2 1/2 years seems to already exceed the typical run of a lithium battery life.

I agree and a new battery would be first on my list!
