I have an iphone SE that i bought about 1.5 years ago. Works fine without any issue. I also charge it without any issue. Very rarely do i charge it overnight where i charge it and then it hits 100 percent and then i dont take it out many hours later but it happens a few times only but i assume this happens to everyone. Is this normal for the iphone to charge to a certain percentage only after having it for some time? I had it for around 1.5 years or so and it works great. If i get a new battery, where should i buy it and how much would it cost? Also does this always happen to phones? I had an old iphone 4s that i bought on ebay many years ago that even though it was used, it was in very good condition. The battery was very good when i used it for over a year and then battery went bad and i had to get at least 3 battery replacements but i did it at those local phone shops where they charge 35 dollars or less only and the battery never hit 100 percent. It always was 80 or less and battery was very poor which is why i got the iphone SE. Does anyone have tips on this? Is there anything i could have done where i caused it? The only thing i could think of would be i charged it overnight but i probably have done that a total of say 3 times during the entire time. Of course there has been times when i charged it to 100 percent during the day while im on the computer and didn't notice and then unplugged it say 1 or 2 hours after i noticed it has already been fully charged. However, i assume everyone has done that and that is no issue right? Surely no one here has never let it charge even at 100 percent and always unplugged it within an hour or less. Thanks.
