How long an iPhone battery lasts and when to replace it

An iPhone battery is designed to keep up to 80% of its original capacity after about 500 full charge cycles, roughly a year and a half to two years of normal use. Past that point the phone drains noticeably faster, and in some cases can shut down on its own. The good news: the battery is replaced quickly, and at iRestore Chisinau we swap it the same day, with warranty.

How to check battery health

Your iPhone tells you the battery state itself. Go to Settings → Battery → Battery Health and Charging and look at "Maximum Capacity". How to read the number:

• 100% - 90%: healthy battery, nothing to do.
• 89% - 80%: normal wear; it may not last quite as long as at the start.
• below 80%: Apple recommends replacement; you will also see the "Battery has significantly degraded" message.

Signs the battery needs replacing

• The phone drops suddenly, for example from 40% straight to shutdown.
• It turns off by itself in cold weather or under load (a game, the camera).
• It gets warmer than before while charging.
• The processor is throttled automatically to compensate for the weak battery.
• Maximum capacity has fallen below 80%.

Why an original battery is worth it

At iRestore we use quality batteries, and for many models we also offer the version with an original controller, which keeps the battery status showing correctly in Settings. A cheap market battery can show wrong percentages, swell over time, or affect the phone boards. The price difference pays off in safety and years of use.

Cost and time

Battery replacement on an iPhone starts from 399 lei, depending on the model. The job is usually done the same day, in 30-60 minutes, and you can wait with us or leave the phone and come back. See the exact price for your model in the calculator on the Service page: pick your model and tap "Battery" to book directly.
