Why iPhone batteries wear out

All lithium-ion batteries have a limited lifespan. Apple designs iPhone batteries to retain 80% of their initial capacity after 500 full charge cycles — equivalent to roughly 1.5-2 years of normal use. From iPhone 15 onwards Apple rates them at 1000 cycles to 80% — but daily charging to 100% and heat still speed up the wear.

As the battery degrades, you'll notice the phone needs charging more often, and iOS automatically activates "Performance Management" — a mechanism that throttles processor speed to prevent sudden shutdowns. Result: a phone that feels slow and dies early, even though the hardware is perfectly functional.

iPhone batteries can swell too: the screen lifts at one edge, a strip of light shows along the side, or the phone no longer lies flat. That's urgent — a swollen cell presses on the display and logic board. Stop charging it and bring it in the same day.

When is it time to replace the battery?

The signs are clear. You don't need to wait until the phone becomes unusable.

iPhone Signs of a worn battery
  • Battery health below 80% in Settings → Battery
  • iPhone shuts down suddenly at 20-40%
  • Performance is throttled by iOS
  • Phone gets excessively hot during use
  • Battery life noticeably worse than 1-2 years ago
  • "Battery Health Unknown" or "Service Battery" message
Warning: Screen lifting at one edge = swollen battery. Stop charging, don't press on the screen, and bring it in today.

Replace the battery or buy a new iPhone?

Many people consider a new iPhone when the battery fails. But if the phone works fine otherwise, a new battery costs 10-20× less and gives it another 2-3 years.

For example: an iPhone 13 Pro with a new battery at 299+ RON vs. an iPhone 16 at 5,000+ RON. If the camera, screen and processor are fine, replacing the battery is the logical decision.

Of course, if the phone has other problems (broken screen, logic board issues, faulty buttons), we evaluate everything at the free diagnostic and give you honest advice on whether the investment is worth it or upgrade is better.

Frequently asked

Do your technicians speak English?
Yes — every estimate, technical explanation and follow-up email is in English if you prefer. We help expats and English-speaking customers daily. WhatsApp is also answered in English.
How long does iPhone battery replacement take?
iPhone battery replacement usually takes 20-40 minutes. Drop the phone off, the technician swaps the battery, and you test it before leaving.
Do you use original Apple batteries?
Yes. We use Apple Service Pack batteries for the most common models. Alternatively, premium OEM-compatible parts — the part type is confirmed with you before the repair.
What warranty do you offer for battery replacement?
Written 3-month warranty on the battery and labour, stated on the invoice. If it fails within warranty, we replace it free of charge. (MacBook batteries get 12 months — see the dedicated page.)
Should I back up my device before bringing it in?
Not necessary — a battery swap doesn't touch your storage. A recent iCloud backup is still a good habit.
Can you test the battery without replacing it?
Yes. Battery diagnostic is free if you go ahead with the repair. You can come to the shop or send the device by courier.
What if my iPhone shows "Battery Health Unknown" after the swap?
On newer iPhones, Apple restricts Battery Health display for non-paired parts. We use original Apple Service Pack parts and, where possible, perform calibration and battery pairing. The battery works at maximum capacity regardless of the message.
Do you accept devices sent by courier?
Yes. Send your iPhone by courier to our Bucharest address. We perform the repair and return it free of charge — you only pay for the repair.
Can I walk in without an appointment?
Yes — walk-ins welcome during business hours (Mon-Fri 08:30-17:30). To avoid waiting, you can call or message us on WhatsApp ahead.
Do you also replace MacBook batteries?
Yes — MacBook Air and Pro, Intel and Apple Silicon, with a 12-month warranty. It has its own page with per-model prices and everything about swollen batteries: /en/repairs/macbook-battery-replacement/.
Do I lose Apple warranty if I replace the battery with you?
If the device is still under Apple warranty, we recommend the authorised Apple service. If the warranty has expired, our intervention does not affect the device's functionality. We use original parts and professional procedures.
