iPhone 14 Pro Max iPhone 14 Pro Max Battery Health (After a Year)

[Macbookey]

11/2022 purchase.

Just dropped again to 92%, this is absurd.

Down to 91% from 93% a week after 17.2. Seems to drop dramatically after some updates for a week or two, then stabilizes. Personally, my battery life continues to be excellent overall. Time will tell how it plays out. My launch day iPhone X was with me for 5 years. I retired it at 83%. Hope this 14PM lasts at least 3, without the need for a battery replacement.

Bought in December 2022. Charged only with Apple wire. Still 100%.

Battery cycles?

It's really weird
bought my iPhone 14 Pro Max in November 2022,
in November 23 it had 97% battery health, 2 weeks later 96%... then 95% and now it's 94%.
This drop happened within 5 weeks

You’re doing much better compared to many others here.

Drops like those are completely normal. My Xʀ on iOS 12 went 100-98-94-93%, and it has been there for a long while.

 

[Macbookey]

Down to 90%. 3% drop in one month. 😬

I only charge with the official 20w charger and by wire or the Apple MagSafe puck. I also do not charge overnight. I set up a shortcut to have Siri alert me when it hits 100%, so that I can remove it from the charger. Followed this practice with great success on my iPhone X. I am looking for 3 years from this iPhone, if a battery replacement is needed in that timeframe, I will just have to pony up for it.

My iPhone 14 from Nov 22 is at 92% health.

It’s on iOS 16.7, not observed any problems with longevity of a charge.

 

[vince22]

iPhone 14 PM (11/22) at 95% health now, installed and update every betas available since purchased.

 

[FlyingDutch]

I’ve just opened a thread about that: bought my 14 Pro Max in January 23 , battery health down to 90%.
this is not normal according to my previous experience with many other iPhone…
im charging with an Apple wireless charger.

Battery cycles?

195 cycles of recharge. Coconut reports a Full Charge Capacity of 4380 mAh with a Design Capacity of 4323 mAh.

Battery percentage depends on battery cycles. You dont have many cycles thats why you still have 100%.

I cannot check cycles on mine (I don’t have a Mac available to install coconut), but I strongly suspect I have FAR more than 195 on mine 🤔

If you are curious, willing, and have agreed to share diagnostic and analytics data with Apple, you can find battery state (and other info) on device:

For example, here’s my iPhone X:

From what I understand, have read, and assume of some of these values:

"last_value_BatterySerialChanged":false

"last_value_OriginalBattery":1

Indicate whether or not the device has had a battery exchange. In my instance, these are correct because my X has never had a battery replacement, direct from Apple or otherwise. Although, it’s questionable why there would be two values for what is essentially the same indicator. Unless, "OriginalBattery" is to report an Apple authorized/authenticated battery.
¯\_(ツ)_/¯

"last_value_CycleCount":1156

Most people reading this know but here’s Apple’s explanation anyway:

Batteries - Why Lithium-ion?

Learn why Apple rechargeable lithium-based technology provides the best performance for your iPhone, iPad, iPod, and MacBook.

www.apple.com

"last_value_MaximumCapacityPercent":75

What’s shown in the Battery Health section of the Settings app. No one outside of Apple knows exactly how this is derived — it could be the highest recorded capacity as of the last charge, an average, or a more complex calculation.

"last_value_MaximumFCC":2796

The actual, original capacity (in mAh), presumably recorded during factory diagnostics. Because the iPhone X had a battery design capacity of 2716 mAh, that means my specific unit began with an extra ~3% (or 103% as reported by utility apps) battery capacity.

December 2022 14PM with 100% battery health

Just used the battery stats shortcut that got posted above. It appears my iPhone is lying about 100% health as its 95% according to this. Probably not even a genuine battery with these numbers? 😂

 

[Ipadlover29]

Bought my 14 pro max in June 2023. Battery health is at 98%. To be fair I charged it with the MagSafe charger. I’ve now switched to the 5 watt charger.

in November 23 it had 97% battery health, 2 weeks later 96%... then 95% and now it's 94%.

Now a week later, my iPhone 14 PM has 93% battery health.

Something is wrong here…

 

[akash.nu]

Down to 87% now after about 15-20 days from last reading.

 

[Lee_Bo]

My launch day 14 PM is currently at 97%. And honestly it probably wouldn’t have dropped at all except for my trip to Arizona & Nevada back in October when I used a MagSafe wireless battery back that got my phone hot.

 

[atari4]

You must post % and battery cycles.

Only percentage doesnt mean anything...

 

[LacrosseChic]

I had my first 14 pro max from launch until may. It was at 198 cycles and 100% health. It cracked and I got an express replacement that I had until October 1. 137 cycles and 100% health. Got a new 14 pro max from work October 1st. Can no longer check cycles because of security measures my job has in place on the phone but had it three months now and still 100%

The 14 PM has an assign battery rating of 4323 mAh. Your battery, like mine, was actually a decent chunk larger than that (mine is 4559) . Relative to the maximum amount, you have 95% of life, but compared to 4323, it’s over 100%.

This is why some people’s batteries show 100% battery health for a longer time, it’s because your battery was larger than the rated capacity amount.

Have you tried the shortcut above?

 

[LacrosseChic]

Have you tried the shortcut above?

Yes it dosent work anymore ( did on my previous phones) because security on my work phone won’t allow me to share analytics and diagnostic data with apple
