If your iPhone barely makes it through the day, you don't necessarily need a new phone. In most cases a battery replacement brings an older iPhone back to the battery life it had when you bought it. Here's how to know if that's your situation.

7 signs your iPhone needs a battery replacement

• Battery life has dropped sharply. If a full charge used to last all day and now doesn't, the battery has worn down.
• The phone shuts off with charge left. Going from 30% to dead is a classic sign of a degraded battery.
• The percentage jumps around. Sudden drops from 40% to 15% mean the battery can't report or hold its charge accurately.
• It runs slower than it used to. Older batteries can't deliver power as reliably, and iOS may limit performance to prevent unexpected shutdowns.
• It gets hot while charging or doing light tasks. Unusual heat is worth taking seriously.
• It only works while plugged in. If the phone dies the moment you unplug it, the battery is done.
• The back or screen looks lifted or swollen. This is a safety issue. Stop using and charging the phone and get it looked at promptly.

How to check your battery health

Go to Settings → Battery → Battery Health & Charging. This shows your battery's maximum capacity compared to when it was new. As a general rule of thumb, once it drops to around 80%, you'll start noticing shorter battery life. A message recommending service is another clear sign.

Should you replace the battery or buy a new iPhone?

If the rest of your phone works well, a battery replacement is usually the more economical choice. It makes the most sense when:

• The phone is 2 to 4 years old and otherwise in good shape
• The screen, camera, and buttons all work
• It still gets the latest iOS updates

Replacing the whole phone may make more sense if it has multiple problems, such as water damage, a failing screen, and an old battery, or if it no longer receives software updates.

What to expect from the repair

Battery replacements are one of the most common iPhone repairs. Before you book, ask any shop:

• Whether the battery is genuine or aftermarket
• How long the repair takes
• Whether the repair comes with a warranty
• Whether pricing is quoted upfront

Frequently asked questions

How long does an iPhone battery last before it needs replacing?
It depends on usage and charging habits, but many people notice a drop in battery life after about two to three years of daily use.

Is it safe to keep using a swollen battery?
No. If your phone's back or screen is lifting, stop using it and have it inspected right away.

Will a new battery make my phone faster?
It can help if the slowdown was caused by an aging battery limiting performance, but it won't fix every cause of a slow phone.

Bottom line: if your iPhone's battery life has fallen off, a battery replacement is often a quick, affordable way to get years more out of the phone you already own.
