Battery health at 95% after 4 months

[chillip]

I have the battery life app and it shows my battery health is at 95% after 4 months and 108 cycles. Is this normal. It started at just over 100%. Thanks

This is a 6S btw.

It'll fluctuate at times and the apps are generally not necessarily the most accurate things when it comes to that (at least not in the smaller ranges).

The fact that you somehow began with over 100% battery health should tell you that such readings are just estimates. Don't stress about it. I would suggest not even looking at your battery health until and unless you observe a noticible decline in your battery life that affects your usage.

iPhone batteries are rated for 80% health remaining after 500 charges. So you should lose roughly 4-5% per 100 charges on average. Now this is an estimate because battery health is typically not linear. If you start having problems with your battery down the road, its possible its defective. But as of now, I wouldn't worry about it.

It is very common for batteries to start at over 100%. The current capacity of my replacement iPhone 6s is 1754/1690, or roughly 104%.

Just because it's common doesn't mean that it's not an estimate which has some margin of error. I'm no expert, but I don't see how a battery can hold a 4% larger charge than what it was physically designed to contain, unless the maximum capacity itself is just an estimate which still means that this all has to be taken with a grain of salt.

That's why I say worry about your battery health based on how it actually performs first, not just numbers that a diagnostic are giving. No offence to the OP, but there are too many people making threads about battery concerns for brand new batteries that in all appearances seems to be perfectly fine, just because a battery health app says the the capacity has gone down a few percent sooner than they expected.

Batteries are rated for a certain capacity, but they can indeed go over that capacity. Batteries aren't a complete science, I can't tell you why they go over rated capacity, but all I know is that it is very common.

Coconut Battery describes it as:

"My current maximum capacity is higher than the design capacity. What's wrong?

"Design capacity" is the capacity your battery should have, when it left the factory. As battery manufacturing is still a more or less chemical process, it may be higher (congratulations) or lower when it is put into your MacBook."


To your second part, I also told the OP not to worry about it unless they start seeing massive battery drain. But it doesn't hurt to check up on your battery health once in a while so you know when to start keeping an eye on it, or practice better charging habits, such as not letting it completely die.

Yeah, I know it's not an exact science, which kind of speaks to my point. The thing about modern lithium ion batteries is that there is actually very little that your charging habits will do to affect their capacity or lifespan. Most devices don't even let you fully discharge, they shut down first. Usually the only way you get a real full discharge is if you leave the battery inactive for a really long time (like months), and if you're not using your phone for months you probably don't care much about the state of its battery anyway.

A cycle is a cycle. If you charge your phone every time it reaches 50% thereby using a half cycle twice as often as charging it when it gets down to the red and using a full cycle, it still adds up to the same in the long run.

Entirely normal.

 

[now i see it]

My new ip6+ is 4 months old. It is in constant use (not just standby) 15 hours a day everyday. I use it like an iPad too.
I keep the battery between 45 and 80% and only charge it to 100% once a month max. Phone is turned off completely every night.
Here's it's stats.

My iPhone x has 95% battery health after 4 months this normal or not ??

Time of ownership is less relevant than how it’s used and the charge cycles.
