iPhone 7/Plus How soon do I need to change my iPhone 7 battery?

[AMSOS]

I've had the iPhone 7 (Bought unlocked from Apple ) since beginning June 2018.

It's been used and charged well. I've mostly charged it diligently between 50 to 80%, and let it run down to 25 every few months, and then charged it up to 100%.

Less than a month ago I updated to iOS 12.1 and I can see that there are fewer bugs and the phone is running pretty smooth.

However, today I went into the battery section and noticed that the Battery Health is now at 99%.

Peak Performance Capability is normal.

It's just been 8 months and there's already a 1% drop in health. Should I expect to have to change the battery before this year is out?

2-3 yrs imho. That’s a pretty low rate. 1% in 8 months.

99% is incredible after all this time. I used to have battery OCD like you seem to have. Let me tell you it's NOT worth it! In order to get an extra 6 months out of the battery you are trying to keep it in the optimal range. It's just tedious and once I started to just charge mine to 100% and forget all the stuff I know about lithium ion batteries, I enjoyed my phone a lot more.

Oh, I see. That’s quite encouraging. Yes, that’s the aim and I’d be a contented first time iPhone owner of my phone lasts that long
Btw, are there any significant improvements in the battery lifespan of the 8 and successive models, when compared to the 7 ??
Thanks!

Ha ha! I know what you mean! Well, I wouldn’t see myself as being obsessed with battery power. But I do take an interest in battery backup issues

iPhone batteries are rated for 500 cycle counts . If you charge your phone 50% yesterday and charge it 50 % today that is one cycle. Typically based on usage you will get 2 to 3 years of good battery. Do not rely on the battery health feature in iOS 12, it is not always accurate. The most important thing you can do when charging your phone is use certified charger.

Jesus my iPhone 7 battery was down to 83% after 2 years. To only have it at 99% you have nothing to worry about at all!

Keep doing what your doing and the battery will last at least another year if not more.. Batteries can be weird and start degrading for all sorts of reasons.

My X (purchased November 2017) is at 93%.
My 7+ (purchased Sept/Oct 2016) is at 91%.

My 6 didn't last 2 years before the battery needed replacement. I replaced the battery and gave the phone to another family member.
The 4 (which was almost 6 years old when replaced by the 6 by the family member) never had the battery replaced.

It is a crapshoot whether the battery will last "forever", or need early replacement.
[doublepost=1549140808][/doublepost]The battery in my iPad Mini 4 needs to be replaced. It will shut down randomly at some point under 30%. I'm undecided whether to pay $100 to have it fixed since I normally use my iPad Pro 10.5" (except for reading books).

 

[now i see it]

It's a $69 iPhone battery, not a $1100 E-bike battery pack. It doesn't deserve any special attention unless you enjoy eeking out the ultimate lifespan

Thanks. Also, I am told if I stay in the 50-80% band it greatly enhances the cycles the battery will last for.
Well, I used the small iPhone charger but it's too slow.
I then shifted to the Anker Power Port with it's IQ quick charging technology along with their MFi certified cable and have never looked back.
Two other things I noticed reassured me - there is little to no extra hear generated when I charge using the Anker, and the Anker charges at exactly the same rate as my MacBook Pro charges the phone.

Oh, it's quite reassuring to hear that. So, when did you have to get it replaced with a new one?

Yes, it definitely seems like they're working hard of improving their battery chemistry.
One thing working against the 7 is that its got a much smaller battery. Assuming that both 7 and 7+ will see similar use, the battery of the 7 will degrade much more quicker.
And I've only heard good things about the battery backup of the "plus" model iPhones.

It is windows only. Click on the details next to battery life and it will give you your number of cycles. If you are a heavy user and your. Artery cycles are over 600 I would get the battery changed.

You're worrying about this more than you need to. Just use your phone and replace the battery when/if you find that it is failing you. It will likely be years from now and you may decide to upgrade for other reasons before the battery even becomes and issue.

I didn’t. I bought an XR and sold the 7

As far as specifics go, sure, staying around that range will be better for the battery, but as far as it being of some sort of a "great" enhancement or even all that much of a noticeable one in real life, especially when compared to the hassle of constantly keeping on eye on and dealing with it all, that's much more debatable and generally doesn't come out as something that's really worthwhile.
