The exact repair depends on the phone model: its construction, adhesive, parts, tools, and service options are not universal.
What a phone battery replacement involves
A replacement removes the battery already inside the phone and installs one designed for that specific model. Because many phones are sealed or use adhesive to hold components in place, the job can require opening the device and following model-specific instructions. A battery kit or guide for one handset should not be assumed to fit another.

The goal is to address a battery that has lost capacity or is faulty—not to guarantee that every battery-related symptom will disappear. A compatible replacement may improve runtime or performance, but the result depends on the phone and the condition causing the problem.

More frequent charging, rapid battery drain, and unexpected shutdowns can be signs of battery aging. Apple says increasingly frequent charging may indicate that battery service is needed (Apple: Batteries); Samsung lists rapid drain and unexpected shutdowns as possible signs and offers battery-condition checks through Samsung Members diagnostics (Samsung battery diagnostics).

These symptoms are reasons to check battery condition, not proof that the battery is the cause. Software, charging equipment, settings, or another hardware fault may also be involved. Use your phone maker’s diagnostic or service guidance before deciding on a repair.
How long a battery is designed to last
There is no universal capacity percentage or age at which every phone battery must be replaced. Published design figures are specific to models and conditions:

| Models | Manufacturer design statement | Qualification |

| iPhone 14 models and earlier | Designed to retain 80% of original capacity at 500 complete charge cycles | Apple specifies ideal conditions; the page does not state a publication year. Actual performance depends on use and charging. |
| iPhone 15 models | Designed to retain 80% of original capacity at 1,000 complete charge cycles | Apple specifies ideal conditions; the page does not state a publication year. Actual performance depends on use and charging. |
| Google Pixel devices | Capacity-retention and cycle guidance depends on device generation and charging recommendations | Google’s guidance is model-dependent; check the relevant device guidance rather than applying one figure to every Pixel. |
These are manufacturer design statements, not mandatory replacement thresholds. Consider the phone’s actual runtime, diagnostics, and service advice together (Google Pixel battery guidance).

Professional service or self-repair?
The right route depends on the exact model, your repair experience, warranty status, and location. Apple recommends trained technicians for iPhone battery replacement and directs customers to Apple or an authorized service provider for built-in lithium-ion polymer battery service (Apple battery service). Google’s guidance is not identical across generations: the Pixel 4a manual says not to remove the battery and directs users to Google or an authorized provider, while newer Pixel safety guidance discusses self-repair for technically experienced adults and warns of hazards (Pixel 4a safety manual; Pixel 11 safety and regulatory guide).

Choose professional service if
- You lack experience opening and repairing phones, or the specific model’s safety instructions direct you to a service provider.
- You want the repair handled by the manufacturer or an authorized provider, particularly if warranty coverage or service eligibility matters.
- You are unsure which replacement part or repair procedure applies to your exact model.
Consider self-repair only if
- You have the technical experience required for that model and can follow its current repair instructions.
- You can obtain a battery confirmed as compatible with the exact model, along with the specified tools and materials.
- You understand that opening the device can cause damage or injury and may compromise water and dust resistance.
Google’s Pixel 10 guidance does not recommend self-repair unless the person has technical expertise; it warns that opening a device can cause damage, injury, fire risk, or loss of water and dust resistance (Pixel 10 repair and safety guidance). Google’s Pixel 11 guide likewise describes the rechargeable lithium-ion battery as a sensitive component that can cause injury if damaged (Pixel 11 safety and regulatory guide).
Use model-specific parts and instructions
A replacement battery should be intended for the exact phone model. Apple warns that a non-genuine replacement may be poorly made, used, damaged, or incorrect for the model, potentially causing fit, performance, software, charging, or safety problems (Apple battery service). Repair materials also vary: for example, the Pixel 7 guide calls for replacement adhesive, while Pixel 6 and Pixel 6a guides include their own pre-disassembly battery advice (Pixel 7 repair guidance; Pixel 6 repair guidance; Pixel 6a repair guidance). Follow the instructions for the precise model rather than adapting another phone’s steps.

What to do if the battery is swollen or damaged
Do not treat a generic DIY tutorial as sufficient guidance for a visibly swollen or damaged battery. Contact the phone manufacturer or a qualified repair provider for instructions; Google directs Pixel users with a swollen battery to repair options (Google guidance for swollen Pixel batteries).
What determines the service route and cost?
Service availability, price, eligibility, and warranty terms vary by phone model, location, and warranty status. Apple notes that prices and terms can vary; Samsung says replacement coverage depends on warranty conditions (Apple battery service; Samsung battery support). Check the current terms for your location and device before arranging service.
