Your phone’s battery isn’t designed to last forever. Over time, chemical aging reduces its capacity, which directly affects performance, charging speed, and even the stability of your phone’s CPU.

🔋 When Should You Replace Your Phone Battery?

According to Apple, when your battery health drops below 83%, it’s a clear sign that the battery’s chemical cells can no longer provide consistent voltage. This causes the system to automatically limit CPU performance to prevent unexpected shutdowns — that’s why older phones often feel slower.

Other signs include:

• The phone gets warm even with light use.
• It drains quickly or jumps from 20% to 0%.
• The back of the phone swells slightly.
• It shuts off suddenly despite showing charge.

If you experience any of these, replacing your battery restores both speed and reliability.

⚙ Why Replacing Late Can Cause Damage

Continuing to use a weak battery stresses your phone’s power management IC (PMIC) and logic board circuits. Over time, this increases heat and voltage fluctuations that can permanently damage those components — often leading to expensive repairs.
