iPhone 8/Plus iPhone battery maintainance tips for my new iPhone 8

This kind of charging doesn't degrade the health as much as the implication.

Any proof one way or the other? Fast charging creates more heat, and heat is the #1 enemy of batteries.

On Samsung phones, there's an option to turn off fast charging in the battery settings. Fast charging is convenient, but there's no debating that it creates more heat. The difference is unknown in terms of how much faster it will degrade the battery. People like to think that because a feature is available, there are no negatives. Anyone who upgrades yearly has nothing to worry about.

Since fast charging has been around for some time on different phones, and it has been possible to charge iPhones with iPad chargers providing more current for some time as well, feel free to show that all of that has a meaningful noticeable effect on degradation.

You'd have to talk to Android users, since these are the first iPhones to allow fast charging.

Batteries start to VERY slowly degrade when over 86F. My old Android phones would routinely get over 86F while fast charging. Fast wireless charging was even worse. Using your phone in the car while charging is probably the worst possible thing for a battery, and how many people do that? Use your phone how you like, but there's zero debate that fast charging causes more heat, and heat kills batteries. It's completely safe, but you are doing an unknown amount of damage to your battery depending on how you fast charge it and if you use it while charging.

Best way to charge is slowly thru the oem cable in a cool room. Worst is to charge it in a hot car while it's running GPS and is mounted in the sun. That would easily be over 100F. Do that several hours a day for a year and your battery will have taken a beating, even if the cycle count is low.

Forget about all this except not letting it go to zero. And use and enjoy it. Don't let all the negative battery posts bother you. I, like joeblow7777, have had and know people who have owned iPhones for several years and never had to replace the battery. There are good tips on getting thru the day better on a charge, but I don't think that was your main concern. Our company uses 5s' and have no issues with throttling and battery replacement.

I agree completely that people should just enjoy the phone. What I can't do is it back and let people say fast charging has zero negatives. That's just not true.

What they’re sayin is just Don’t use it

This. If you are worried, just don't use it.

I say, just use the phone, charge it when you want and it will last a long time. The battery in my 6S+ lasted two full years before the capacity dropped to 70% and I got it replaced last month.

And a follow-up to show variation, my 6s Plus was 2.25 years old and was at 87% when I turned it in to Best Buy. I charged it several times a day. Rarely let it get below 60%. Apple is not trying to degrade anything. Just employing battery management. A feature they are going to add to future iPhones. A reasonable argument is they should have told consumers of the throttling and why. 2 sides to that story also. Bottom line---enjoy the iPhone.

You used the quote feature wrong so what you typed looks like I wrote it instead of you.

Try to keep the battery level between 20-80%. Don’t leave the phone plugged in after the charge is complete.

My iPhone 6+ has been plugged in to my Macbook pro 95 percent of the time and after 3 years the battery condition is at 85%.

Exactly. The battery will only charge when it drops to a certain level just like your MacBook Pro does. I've left phones connected to the charger for a whole week before and never damaged the battery in any way.

My 6S after two full years has a capacity of 89% with 203 cycles.

Few months ago i got a Job and i Bought an iPhone 8 from my hard earned money.
Now seeing many roumors that apple intentionally throttling CPU’s of iPhones

So Any tips for elongated Battery life span?
Because I don’t want to spend $80 for battery replacemnt after 1yr
I’m willing to use this phone for atleast 3-4years

I mean charging and sync does it wear out more battery?

I don’t use wireless charging
And does draining completely and topping to 100% does this practice increases wear level early ?

Apps that constantly use gps will kill your battery.

Oops, sorry. Not adept at all this--

Wow this thread is loaded with a lot of nonsense. Just use the device and when it needs to be charged charge it then repeat.

There's a difference between zero negatives and meaningful noticeable degradation.

 

[JackieInCo]

Just to show you that the battery doesn't continuously charge while plugged in, here are two screen caps. The first is from my 6S fully charged. notice the charging state. The second cap is from my 6+ which is actively charging. The 6S is not charging at 100%. It's been plugged into my MBP since last night.

A fast charged galaxy S7 would routinely lose 20% in a year.. that's why Samsung batteries are a new long life technology that only loses 5% per year for the s8/ note 8

Yeah, the slow battery degradation (only 5% per year according to Samsung) is a great feature to extend the longevity of the S8 / Note 8... especially since the S7 and earlier models would lose up to 20% per year.

Since apple is officially said in a statement that MacBooks charging brick works as a fast charger

Does it mean apple intensionally want to degrade battery health
Also i use a 10Watt iPad mini charging brick does it destroy battery early?

No. Faster charging wears the battery only slightly more, you probably won’t notice the difference. Best advice is not to let it drop to 0 too many times, everything else is overdoing it. Use quality chargers and that’s it.

It should last you several years.


Oooor, you can completely get paranoid and go all conspiracy on this one: yes, Apple is recommending fast charging because they want your battery to fail faster so they can slow down your phone and slow down your computer and then slowly radiate your room with some strange particles that will cause all the hair on your body to start falling off until it eventually mutates into a hair-beast that will throw you out of your own home and force you to buy a new home, one made by Apple. But that is only the beginning because after a few years that home will start to shrink slowly until it’s just as big as a shoe box. Then, phase II of Apple’s plan can begin....
