You ever been waiting on an important call, only to have your iPhone shut off or drain strangely fast? If so, it might mean your battery’s lifespan is slipping, and it’s time to maintain or even replace it. Phonefix will guide you through the essential knowledge of iPhone battery life, how to judge when replacement is needed, tips to prolong its life, plus tool and platform suggestions to help you tackle battery replacement with ease.
I. Battery Health
iPhone batteries degrade over time. This is a natural process that all batteries face. Apple uses lithium-ion batteries, which have decent longevity, but they’re still influenced by usage habits and environmental factors.
Main signs: Reduced battery capacity, weaker endurance, unexpected shutdowns, app lag, frequent charging, even lower speaker volume—all of these may signal battery issues.
How to check battery health: Go to Settings, tap Battery, then Battery Health & Charging. You’ll see a percentage labeled Maximum Capacity, indicating how much your battery remains compared to a new one. If this drops below 80%, you should consider replacing the battery.
Tip: When checking battery health regularly, combine the system info with a iPhone Battery Tester to gauge detailed status and detect whether the battery really needs replacement.
II. Battery Lifespan
Battery health depends on charging habits, temperature exposure, and other factors. Generally, different usage patterns result in varying lifespans:
Normal use: In 1 to 2 years, battery health often dips below 80% and replacement is recommended.
Heavy use: Frequent charging accelerates degradation.
Light use: With good habits, a battery might last 3 years or more.
III. iPhone Charging Habits
Your charging habits play a crucial role in battery health. Here are things to watch out for:
Good Habits
1. Keep your battery between 20% and 90% to avoid stressing it with full charges or deep discharges.
2. Turn on Optimized Battery Charging in settings to slow aging.
3. Use high-quality iPhone Charging Cable and power adapter to ensure safe, stable charging and avoid damage to internal components.
Bad Habits
1. Frequently charging to 100% can speed up battery wear.
2. Regularly letting the battery drop to 0% puts stress on it.
3. Charging overnight keeps the iPhone at full charge for too long.
IV. DIY iPhone Battery Replacement
If you choose to replace battery yourself, prepare the following tools and components:
Screwdriver set: compatible with iPhone screws such as Pentalobe and Tri-point.
Suction cup: to safely detach the screen from the body.
Pry sticks: to open the case without scratching components.
Battery adhesive strips: to secure the new battery in place.
Anti-static tweezers: Use an Anti-Static Ceramic Tweezers for handling flex cables and connectors safely.
Heating tools: You can choose hot air gun or YCS Heating Pad to soften adhesive under the screen or battery.
After preparing all the necessary tools, you can proceed with the battery replacement by following these steps:
Step 1. Completely turn off your iPhone. Attach the suction cup to the bottom of the screen and gently pull to create a small gap. Use a pry stick to carefully loosen the screen along the edges—be cautious not to damage the top cables.
Step 2. Wear anti-static gloves and use the anti-static tweezers to lift the battery connector’s plastic tab. Carefully disconnect the connector to avoid damaging the cables.
Step 3. Heat the back of your iPhone for 2–3 minutes to soften the adhesive. Carefully pull the tabs on the old battery to remove it. Then align the new battery with the slot, place it in, and secure it with Battery Adhesive Strips. Ensure the battery sits flat.
Step 4. Reconnect the battery connector and fasten the tab. Reattach the screen and turn on the iPhone to check battery health and test all functions.
