With the exit iPhone 15 Pro Max Users expected high performance, improved autonomy and long battery life. But after 9 months of active use, many owners began to have questions:
📉 Why is the capacity level dropping faster than expected?
🔥 Why does my iPhone sometimes overheat when charging or playing games?
💡 And how to properly care for the battery of this model?
Let's figure out what happens to the iPhone 15 Pro Max battery during this period of operation.
📱 Key Features of the iPhone 15 Pro Max Battery
Apple has installed a battery with a capacity of 4422 mAh, and the company claims it should provide up to 29 hours of video viewing.
Apple was also the first to use USB-C instead of Lightning, which potentially speeds up charging and makes the device more versatile.
However, already in 6-9 months Users have started to notice a decrease maximum battery capacity in the battery settings.
📊 What do users say?
On average, according to reviews:
-
After 3 months – 100–99% battery condition.
-
After 6 months – 97–95%.
-
After 9 months – 92–93%, and sometimes lower.
Some people complain that the battery wears out faster, than previous models, especially under intensive use (gaming, shooting 4K video, working with graphics).
🔥 Why does this happen?
1. Increased loads
iPhone 15 Pro Max comes with a chip A17 Pro, which is incredibly powerful, but at the same time more demanding of energy. Modern games and applications literally "eat" the charge.
2. High temperatures
The metal body with titanium inserts looks nice, but it can get hotter. And heat is the battery’s main enemy.
3. Frequent fast charging
Using powerful chargers (20-30W) every day leads to accelerated wear of the battery, especially if the phone is charged to 100% and is in use while charging.
⚠️ What problems are already emerging?
-
📉 Rapid battery drain, even in standby mode.
-
♨️ Overheating during games, calls or charging.
-
⚡ Takes longer to charge with reduced capacity.
-
🔌 The phone may unexpectedly turn off at 10–20% charge.

🔋 Charge up to 80–90%, and not up to 100%.
-
⚡ Avoid fast charging every day.
-
