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.
1. Your phone does not last the day
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.
2. It shuts off with charge left
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.
3. The percentage jumps around
Dropping from 40% to 10% in a few minutes, or jumping back up after a restart, is a classic sign of a worn battery.
4. The phone feels slow
Some phones slow down the processor when the battery is weak to prevent sudden shutdowns. A new battery can bring the speed back.
5. It gets hot
A phone that runs warm during normal use or while charging may have a battery problem. Have it checked.
6. The screen or back is lifting
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.
How to check battery health
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.
