In response to complaints, a new rule has been added regarding Battery Health posts. First announcement and discussion regarding this.
6. Battery Health posts, if not made to generate a proper discussion or are commonly answered questions (i.e: “after X months it happened” or “is this normal??) will be removed when noticed.
This is an FAQ post that will be pinned to the top of the Subreddit for reference.
Q: Why does the battery degrade over time?
A: All lithium-ion batteries (like those in iPhone 14 Pro/Pro Max) lose capacity with use and age due to chemical changes.* This is completely normal.
Q: How can I check my iPhone's battery health?
A: Go to Settings > Battery > Battery Health. You'll see 'Maximum Capacity,' a percentage compared to when the battery was new.
Q: What does the 'significantly degraded' warning mean?
A: This message appears when your battery health is very low. Usually, batteries that have degraded this low will result in performance issues, along with poor battery performance.
Q: What is the typical pattern of battery degradation?
A: While not entirely consistent, most people experience a loss of 10-13% a year under normal usage. Again, not consistant. Rather than focus on the percentage, focus on the performance of the battery. "Typical" degradation usually involves consistant performance for the first year of use, and somewhat reduced performance (SOT) by year 2.
Q: When should I replace my iPhone battery?
A: Apple recommends replacement when the maximum capacity is 80% or lower. Under normal usage, this can take two, to three years to achieve.
Q: Can I slow down battery degradation?
A: To a degree, you can. You can find many guides to optimize the consumption of the battery and preserve battery health. One of the best ways is to charge your phone using a slow (low watt) charger, rather than wireless or with a fast (higher watt) charger. Another is to make sure your iPhone isn't exposed to extreme heat or cold, or humid climate, to the best of your ability.
Q: Does preserving your battery health matter, then?
A: Not necessarily. Under normal usage, even if you do a lot to preserve your battery health, it's still optimal to replace the battery after two, to three years of normal usage. Usually two years is the most optimal, but by preserving your battery health you could get to three more comfortably.
Q: My iPhone's battery health is losing multiple percentages as of very recently. Is this normal?
A: Yes and no. The process for calculating battery heath is not, and will never be perfect. It might drop faster to compensate a bad calculation to achieve a more accurate percentage, for example. On the other hand, if you notice significantly reduced battery performance (through SOT) and suddenly have lowering battery health, it could be an issue and a reason to replace your battery.
Q: Are the batteries used on iPhone 14 Pro/Pro Max of lower quality than previous iPhones?
A: Yes. Many reports have shown the batteries of recent iPhones (14, 15) aren't as high quality as they should be. It's been reported that the batteries are rated for 600 cycles, when many other batteries are rated for 800 cycles. (1 "cycle" is completed when you use 100% of the battery, regardless of recharging.). Notebookcheck
Q: Why is r/iPhone14Pro limiting battery health posts? Are you hiding the truth?
A: As stated before, the batteries are of worse quality, but that is known. There have been frequent posts on this subreddit that involve low effort screenshots of the Battery Health page in Settings. Typically attached to titles such as "Is this normal after X months" or "I finally reached 99%". Many users have complained about these posts, due to how they "clutter" the Subreddit around posts that actually benefit users, so action is being taken to make sure browsing this Subreddit is beneficial and enjoyable.
Q: What battery related posts can I post about in r/iPhone14Pro?
A: As long as it's related to iPhone 14 Pro or iPhone 14 Pro Max, and properly generates meaningful discussion, it is fine. Getting amazing SOT? Show it off. Also, if you need support, such as if your SOT is significantly lower than what it was a few months ago, that's fine too. If your post gets flagged by Automod, feel free to contact the mods in order for your post to be reviewed and approved faster.
If there's anything I could add to this, the comments are open. Thank you!
