Howdy folks,

So today was my first real battery life test of my iPhone 8 as it's the first day I had to go to work since I got it.

I'm happy to report that battery life for me has been exceptional. It was off charger for 10 hours and when I got home from work I was still at 72%. I was doing a moderate amount of texting, some browsing and quite a bit of camera use. I also have fitness tracking apps constantly running in the background. I was not using WiFi at all.

This is very good battery life by my standards, in fact it stayed over 90% even three hours into my shift.

This beats out my previous champs which were my Google Pixel and my Lumia 1020.

With my Pixel I'd be at around 55% at the end of the day with similar usage.

I'm using an iPhone 8 64GB (4.7)

How has your battery life been?

Battery life is great, but not as great as my iPhone 7 Plus. As long as I can go from around 7 AM when I’m walking out the door to bed time, that’s all I care about. I’m in an office setting all day so if I were experiencing bad battery life, I have a wireless charger at my desk.

Sadly I don’t think you can draw any conclusions from this because when you put a new battery in an iPhone, you get great battery life for a while at least. I replaced the battery on my iPhone 6 after 2 years and the difference was ridiculous. My iPhone 8 currently has great battery life but it’s only in line with what I’d expect from a new phone.

That’s very true, lithium ion batteries tend to lose their charge overtime.

Yep. iPhone batteries are designed to retain 80% of original capacity for 500 full charge cycles. After that you’re on borrowed time.

But battery life on these new phones are amazing. My red iPhone 7 Plus was only 3 months old. So not many charges on that. Battery didn’t have many full charges. My 8 plus I’d say is getting about 30% more battery life. And I may being conservative on that. Maybe closer to 40%. It’s fair to say A11 Bionic which Apple said that this chip is much more power efficient is correct. I’m completely amazed about this battery life.

30%?
That’s HUGE.

Apple mentioned it to be 500 cycles.
750/1000 for some of the MacBook models.

That’s funny because I went to Apple to get my iPhone diagnosed and get a new battery. My capacity was 90% at 586 full charge cycles. I asked the tech about 500 cycles and they said the new Li-Poly batteries are 750. So I said “ok” and went and bought a coffee from a local shop.

The End

Hmm.. you can start a Live Chat with Apple Support, and see whether it’s 500 or 750.

I can draw one conclusion for sure: It beat my LG G6 and Google Pixel when they were of comparatively new status. The LG G6 has to power a much larger screen, however the Pixel isn't much larger yet has a 2770 mAh battery compared to the iPhone 8's at 1821 mAh. As much as I love the Pixel the iPhone has it beat there.

By full charge cycles do they mean from near 0% to 100%? Or just any time it's charged?

I rarely keep phones for longer than a year anyway, so I doubt I'll wear out the battery significantly.

last year with the 7 it had great battery life for a few months then it went down the drain. It is awful on IOS11. Just expect it to drop in a few months.

A charge cycle would be the equivalent of 0% to 100%. In other words, charging from 50% to 100% would be considered half a cycle.

Gotcha,

Well in my case I doubt I'd ever come close to wearing the battery out before I get a new phone. I'm not a heavy user and my phone rarely gets below 50% before I can put it on a chargers.
