IPhone X new battery drains fast

[iphonecarbonx]

I had my Iphone X battery replaced at an apple certified shop about a month ago as it was at 75% battery health. About a month in now still shows 100% health but it seems that’s it is still draining quite quick, although for sure better than before. Could it be a faulty battery or is this typical? Here is my battery graph after a typical day. Thanks all

If you got eight hours thirty-nine minutes of screen on time and almost two hours screen off time on a fully charged battery I wouldn't complain

Not bad. And of course, keep in mind that even new batteries that are lying in the warehouse are not 100% of full capacity (depends on battery age)
And, the newest iOS/iPadOS on older devices will drain battery slightly faster (but maybe it's just my concern)

Ok, do you think it would hurt to contact the shop that did my replacement and ask them if they could put another battery in, since i do have a 90 day coverage? do you think it would make a difference? thanks

If the shop is an Authorized Apple Service Provider they'll have diagnostic equipment that can test the battery. If it passes they likely won't replace the battery.. Of course it never hurts to ask and you never know, you might get them to replace it even if it tests ok
