Understanding Battery Charging Fundamentals
Before lithium-ion batteries became the standard, nickel-based batteries were widely used. The shift to lithium-ion technology happened because of the many advantages it offers, including faster charging, lower self-discharge rates, longer lifespan, and a smaller environmental impact. Unlike nickel-based batteries, which contain toxic cadmium, lithium-ion batteries are safer and more efficient. When you charge a lithium-ion battery, energy from the charger moves lithium ions from the cathode to the anode with the help of an electrolyte.
Your phone’s battery doesn’t charge at a consistent speed from 0% to 100%. Instead, the process occurs in three distinct stages:
● Bulk Charging: In this phase, the battery charges quickly from 0% to around 70-80%. The goal is to replenish the battery as fast as possible.
● Absorption Charging: Once the battery reaches 80%, the charging speed slows down. This is done to prevent the battery from overheating and to manage the charging process more efficiently.
● Trickle Charging: In the final stage, the charging slows to a near halt, or sometimes pauses temporarily. This phase helps protect the battery’s overall lifespan by preventing overcharging.

Why Your Phone May Stop Charging at 80%
1. Your Phone is in the Trickle Charging Phase
When your phone hits around 80%, it enters the trickle charging phase. During this time, the charging speed slows dramatically. This gradual pace helps reduce stress on the battery and contributes to its long-term health. Think of it like slowing down as you approach a red light: a little patience now can save you later. Most modern smartphones incorporate this feature to ensure optimal performance over time.
Trickle charging also plays a key role in managing heat. Heat is one of the main culprits behind battery wear and tear, so slowing down the charging process helps keep the temperature in check. If you tend to charge your phone overnight, this phase prevents overcharging by reducing the flow of electricity once the battery nears full capacity, ultimately extending your device’s lifespan.
2. Optimized Battery Charging
Apple introduced Optimized Battery Charging to help users extend the lifespan of their batteries. This feature learns your daily charging habits and pauses charging at 80% until it’s necessary to finish charging to 100%. For instance, if you charge overnight, your iPhone may hold the charge at 80% until just before you wake up, completing the final 20% as needed.
This feature is particularly helpful for those who don’t always need their phone to reach 100%. By delaying the last part of the charge until just before you use the phone, Optimized Battery Charging reduces the time the battery spends at higher voltage levels, which can cause wear and tear over time.

3. iPhone Battery Management System (BMS)
The Battery Management System (BMS) in your iPhone is like a personal trainer for your battery, ensuring it stays in top shape. The BMS monitors the battery’s health and adjusts charging speeds accordingly. If the system detects that the battery is getting too hot or has aged, it will stop charging beyond 80% to prevent further damage. Fast chargers tend to generate more heat, which can stress the battery. The BMS constantly evaluates various factors, such as the battery’s age, usage patterns, and temperature, in the background to ensure optimal performance.
For example, if the battery has gone through many charge cycles, the BMS may limit the charge to 80% to reduce stress. Similarly, if the phone is heating up during fast charging, the BMS will delay the process to avoid overheating and preserve battery health.

4. Charging iPhone – Limits for iPhone 15 and Later
With the release of iPhone 15 and later models, Apple introduced new options to give users more control over how much the device charges. Now, you can set the iPhone to stop charging when it reaches either 80% or 90%. This feature adds another layer of protection alongside Optimized Battery Charging, helping to further extend the lifespan of your battery.

5. Dirty Charging Port
Sometimes, the simplest explanation is the right one: your charging port could be clogged with dust or debris, preventing your phone from charging properly. Over time, lint from pockets or bags can accumulate in the port, causing the charger to seat incorrectly. Regular cleaning of the charging port can help avoid this issue and ensure smooth charging.
6. Hardware Issues
A faulty charging cable or adapter could be the reason your phone isn't charging correctly. Often, simply using a certified charging accessory can solve the problem. Uncertified chargers may not supply a consistent power flow, leading to interruptions in the charging process. Additionally, wear and tear on the connectors of the charging cable can cause poor contact with your phone’s charging port, resulting in charging issues.
7. Software Issues
Third-party applications and bugs in your phone's operating system can also cause charging issues. These problems are often related to software conflicts or background processes that interfere with the charging process. In most cases, restarting your phone or installing the latest software update will resolve these issues. Keeping your device updated ensures that any bugs affecting charging or battery performance are fixed promptly.
How to Fix the 80% Charge Problem
1. Turn Off Optimized Battery Charging
Temporarily turning this feature off will finally allow your phone charge to 100%. You can always turn it back on when you're concerned about battery health.
How to Turn Off Optimized Battery Charging:
● Open the Settings app.
● Tap on Battery.
● Tap on Battery Health & Charging.
