iPhone 12 Pro Battery health comparison iPhone 12 Pro with iPhone 11 (different usage)

[Valter_Almeida]

Hi everyone,
I have an iPhone 12 Pro, and my wife has an iPhone 11. My way of usage is the best for my battery health, and her use is the worst for her battery health (full bright, recharging all the time etc.). In the end, both iPhones now have 88% battery health. Could someone please explain why we both have the same battery life despite being cautious with the battery? Is this battery health information reliable?

I think you might be confusing battery life with battery health. Battery life generally refers to the number of hours your battery lasts before needing to be recharged (e.g., 10 hours). Screen brightness definitely affects battery life. Battery health is a fuzzy metric that's very vague, and it's not affected by things like screen brightness nor is it significantly affected by charging habits. It's more affected by battery cycles and age. And to answer your question, no it's not in any way reliable. It's just a metric that Apple uses to determine whether a battery is eligible for warranty service. It serves no real value to users.

Post information referencing charge and discharge cycles for each device as well please. It’s all located in the log aggregated files.

Hi chabig, Yes, I have confused the names! Now, it is fixed. Thanks for your answer and comment! ??

By reading the results of folks within this forum recently the conclusion I’ve drawn is that the new devices have poorer quality battery cells. But that’s just an assumption on my part.

12-series is said to use ‘cheaper batts’

…My way of usage is the best for my battery health, and her use is the worst for her battery health (full bright, recharging all the time etc.)….

…despite being cautious with the battery?….

You’d have to define what you think ‘best’ and ‘cautious’ is, it may not be what you think. For example, she could plug-in/full-equiv-cycle 3x as much as you within a middle/lower SoC band and still come out ahead you if tend to keep your phone ‘topped-up’ in the upper SoC band.

The battery diagnostic of the iPhone 12 Pro has passed, but I still don't understand why the battery health stats are the same between the devices. Reppans, I use only five apps simultaneously (background), barely use full brightness and rarely my phone is hot, recharging only with apple or Belkin charges. She uses 50 apps in the background, full brightness, and the phone gets hot now and then and uses hundreds of different types of bricks and chargers for charging her phone.

I am start thinking that new devices have poorer quality battery cells as Limeybastid said.

Apple used a smaller battery in the iPhone 12 to accommodate the QualComm 5G modem. With the iPhone 13 Apple upped the battery size again. Battery life for the iPhone 13 is much better. For instance, the battery life on the 13 Mini rivals the battery life of the larger iPhone 12.

I didn't know that. They have said that the battery has improved from iPhone 11 to iPhone 12 upgrade and not the contrary. Anyway, that's good to know. Thanks, Taz.
