Quick answer
Your phone battery likely needs replacement if the phone does not last the day, shuts off with charge left, the percentage jumps, it feels slow, or it gets hot. A swollen battery that lifts the screen needs attention right away. Most battery replacements at ART & FIX are done the same day.
Every phone battery wears out with time and charging cycles. The good news is that a battery replacement is one of the quickest and most affordable ways to make an older phone feel new again. Watch for these signs.
If a phone that used to last all day now needs a charger by lunch, the battery has probably lost much of its original capacity.
A phone that turns off at 20% or 30%, or when you open the camera, has a battery that can no longer deliver steady power.
Dropping from 40% to 10% in a few minutes, or jumping back up after a restart, is a classic sign of a worn battery.
Some phones slow down the processor when the battery is weak to prevent sudden shutdowns. A new battery can bring the speed back.
A phone that runs warm during normal use or while charging may have a battery problem. Have it checked.
If the screen is pushed up or the back glass has a gap, the battery may be swollen. Stop charging the phone and bring it in right away. A swollen battery is a safety risk.
On an iPhone, go to Settings, then Battery, then Battery Health. Many Android phones show battery information in Settings or in the device care section. A low health reading together with the signs above means it is time.
We test your battery, replace it with a quality part, and check charging before you pick it up. Most battery replacements are done the same day. See estimates on our pricing page.
Go to Settings, then Battery, then Battery Health. A low maximum capacity together with fast drain or shutdowns means it is time for a new battery.
