    Battery health maximum capacity

    Hello everyone, so does the battery health maximum capacity ever go lower than 73% on the iPhone? Mine has been in 73% for I below over six months, and since hasn't degraded anymore 🤷🏼*♂️.

    Anyone have any old iphone batteries that are worse than 73% max capacity?!

    I recently replaced my 6S battery at 57%. It had had about 1700 charges and would give 1 - 2 hours of use after a 2.5 hour charge.

    Keep in mind that cell phone batteries typically last 2-3 years before it is time to replace them. Often, when the phone is older, it may be cheaper to replace the phone then try to get a replacement battery installed. Often those replacement batteries won't be OEM and may not last as long.

    It seems that the iPhone batteries don't last as long as they used to. I replaced my iPhone 6 battery at just under 2 years before I gave it to my brother in law 3 years ago. The iPHone 5 I had before that bulged 2 years ago (It had lasted 5 years). My sister's 2 year old SE shut down recently, and now says it needs service. My current X says service at 2 years.

    My iPhone 4 never needed a replacement battery. The 3G didn't either, but that phone wasn't used as long either since it was obsolete so fast.
    iPhone X is my current primary phone. I have older model iPhones and Moto phones available on other lines. Currently prepaid, though would consider postpaid on right plan.

    I’m convinced the new batteries aren’t as good. I had similar experience

    Part of the problem is that there haven't been any major battery technology developments in the past few years and we are using our phones to do more tasks almost exponentially.

    In addition, most consumers don't want to pay more for their phone than they have to (not that I don't think the phone manufacturers are making obscene profits).

    So the last 2 phones of mine that I used exclusively for 2 years each have had battery issues. The 1 in between was only 1 year (I still have it, but it is a backup phone that isn't always on) is still fine.

    My Mini 4 needs a new battery at some point. I replaced it for day to day use with an iPad Pro, so it hasn't been in any rush to get repaired.

    Sadly, the battery is the weakest link for most cell phones.
