Do not waste money on a replacement battery.
Yes. You read that right. I am advocating that you do not replace a failed cell phone battery. A failing battery is the first and usually most visible sign that your phone is failing. You should replace the complete phone.
A story for you.
Daphne is cheap. “How cheap?” you may say. Daphne could rub Abraham Lincoln’s face off a penny. That’s how cheap she is. One day, Daphne noticed her phone lost 60% of its charge during a 10 minute phone call. Daphne was puzzled. She fully charged the phone, made some more calls and once again discovered she had lost 60% of the charge within 10 minutes. “That’s not how it used to work,” pondered Daphne.
She went online and found someone who could open her phone, replace the battery and get everything working again. Daphne hired him. The project was done within an hour. Daphne was happy. She extended her phone’s useful life.
A few days later, the phone started freezing while looking at maps, weather forecasts and calendar items. She backed up her data and perfomed a hard reset. She then re-synced the phone and recovered all her data.
The issues continue. Daphne became even more frustrated. She went to her carrier’s retail outlet and bought a new phone. She incurred the cost of a new phone and the cost of replacing the failed battery. Had she just replaced the phone, which was inevitable, she would have saved the cost of the replacement battery.
Daphne should have realized the phone was on its last legs. Batteries do not have moving parts. When a battery starts failing it is a sign the entire phone is failing. Save yourself the headache of spending money on failing technology. Replace the entire device as soon as parts start failing.
