Yes — you can replace almost any phone battery yourself at home, and it's one of the most cost-effective DIY repairs there is. Whether you own an iPhone, Samsung, OPPO or Pixel, the process is similar and takes 20–40 minutes with the right kit.
Signs your battery needs replacing
- Maximum capacity below 80% (iPhone: Settings → Battery → Battery Health)
- The phone dies quickly or shuts down unexpectedly
- It gets hot while charging
- The back panel is bulging — a swollen battery, replace immediately
What you'll need
A model-matched replacement battery, precision screwdrivers, a suction cup, plastic pry tools, and adhesive strips — all included in a SelfRepairKit battery kit.
The basic process
Power off, remove the bottom screws, warm and open the phone, disconnect the battery connector first, ease out the old battery by its adhesive tabs, fit the new one, reconnect and test before sealing. Never bend or puncture a lithium battery.
Is it safe?
Completely, if you follow the guide and don't rush. The only jobs to leave to a professional are water-damaged phones or a device that won't power on at all.
