iPhone battery capacity dropped 5% in 3 months

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.

Protect & Prolong the Life of your iPhone's Battery:

1. About the battery usage on your iPhone, iPad, and iPod touch ...
2. Batteries - Maximising Performance - Apple (IN)
3. iPhone Battery and Performance

Try to monitor Battery usage by iPhone Activity as shown below

What is shown under battery usage? Checking that would give you an indication of the usage behavior.

1. Background Activity
2. Notifications
3. Connected to Charger
4. Or any Other

See the pic below (iPhone 12 Pro iOS 17.3.1)

"Show Activity" feature will show you more info see the pic below

Try some of these options too.

To prolong the life of your iPhone battery, you can follow these tips and best practices:

1. Optimize Battery Charging: Enable the "Optimized Battery Charging" feature on your iPhone. It helps reduce the wear on the battery by slowing down the battery aging process. You can find this option in Settings > Battery > Battery Health. About Optimized Battery Charging on your iPhone - Apple Support (IN)
2. Avoid Extreme Temperatures: Extreme temperatures, both hot and cold, can negatively impact your battery life. Avoid exposing your iPhone to excessive heat or cold, such as leaving it in direct sunlight or in a freezing car.If your iPhone or iPad gets too hot or too cold – Apple Support (UK)
3. Use Original Chargers and Cables: Always use Apple's original chargers and cables or certified third-party accessories. Low-quality chargers or cables can damage the battery and reduce its lifespan. Identify counterfeit or uncertified Lightning connector accessories - Apple Support (IN)
4. Avoid Draining the Battery to Zero: Charge it whenever the charge becomes lower than 20%. The rest is up to you when to charge. how long to charge, how often to charge, which adapter to use starting from 5W to 140W USB-C Power Adapter etc.
5. Optimize Display Settings: Adjust your display settings to optimize battery life. Lower the screen brightness, enable auto-brightness, and use shorter screen timeout durations. Adjust the display and text size on iPhone - Apple Support (IN)
6. Minimize Background App Refresh: Limit the number of apps allowed to refresh in the background. Go to Settings > General > Background App Refresh and disable it for apps that don't require real-time updates. Switch apps on your iPhone, iPad, or iPod touch - Apple Support (IN)
7. Disable Push Email: Push email notifications can drain your battery quickly. Instead, set your email accounts to fetch data manually or at longer intervals. You can change this setting in Settings > Mail > Accounts > Fetch New Data.
8. Disable Unnecessary Notifications: Reduce the number of unnecessary notifications you receive. Go to Settings > Notifications and customize which apps can send you notifications.
9. Limit Location Services: Some apps use GPS and location services in the background, which can drain your battery. Go to Settings > Privacy > Location Services and disable location access for apps that don't require it.

I’ve had my phone for 3 months and got it with 97% battery capacity, it’s now at 92. I’m charging wisely, have it between 20-80% most of the time, I don’t let it overheat but it feels like it’s going down very fast. I fear, I will need to change the battery in a few months with that pace. I’ve seen people here that say that after 12 months, they still have 97%.What is happening?

No two phones will exhibit the same battery health after a certain period of time, because no two phones are used in the exactly the same way. To have purchased an iPhone which came with a battery health of 97%, you must have purchased a used iPhone from someone?

The better measure to understand your battery health is Charge Cycle. Open Settings > Battery > Battery Healht - how many Charge Cycles does it show. For an iPhone 14, for about every 25 charge cycles, you may see about a 1% drop in battery health.

Battery Health decline is NOT linear, meaning it can remain steady for a while, then drop a few points faster. That in itself is not cause for concern.

You also suggest you're using the Charge Limit in hopes it will demonstrably improve battery health. Most of us believe the charge limit is more hype than not. A respected engineer actually did a test to see if it helped in any way over a full year, compared to the same model phone, both used exactly the same in the same location for a year. It didn't do anything to preserve the battery. If anything, you'll typically charge your phone more often using a charge limit. Most of us who have been on this forum for years, plug our phones in to charge when we go to bed at night and use Optimized Battery Charging, where the phone will charge to 100% by the time you wake up and if connected to Wifi, backup nightly as well.
