If your phone used to last all day and now needs a top-up by lunch, you're not imagining it. Phone batteries are lithium-ion, and every one of them slowly loses capacity with each charge cycle. After a couple of years of daily use, most hold noticeably less than they did out of the box.
The good news is that a worn-out battery doesn't mean you need a new phone. Battery replacement is one of the most common repairs we do at our Horsham shop, and it can give an older phone plenty of life. Here are the signs it's time.
This is the big one. If you're charging two or three times a day with the same habits you've always had, the battery has lost a real chunk of its capacity. A quick check: if the percentage drops fast even while the phone sits idle in your pocket, the battery is likely the culprit rather than a single power-hungry app.
Your phone says 25 percent, then suddenly goes black. Or it dies in the cold, or the moment you open the camera. A worn battery can't deliver steady power when the phone asks for a burst of it, so the phone shuts down to protect itself. When you plug it back in, it often jumps right back to a much higher percentage than it should.
An aging battery can make the whole phone feel sluggish. On iPhones, if the phone has had an unexpected shutdown, iOS may turn on performance management to prevent it from happening again, which can slow apps and lower screen brightness. A new battery usually brings that speed back.
Phones get a little warm while charging, but a battery that runs hot during normal use, takes far longer to charge than it used to, or has a percentage that jumps around is telling you something. Heat also speeds up battery wear, so the problem tends to snowball.
This one is a safety issue, not just an inconvenience. As some lithium-ion batteries fail, they can puff up. Watch for a screen that's lifting away from the frame, a gap along the edge, a back that's bulging, a phone that rocks when you set it on a table, or a case that suddenly doesn't fit. If you see any of these, stop charging the phone, don't press on it or try to pry it open, keep it away from heat, and bring it in as soon as you can.
Go to Settings, then Battery, then Battery Health (called Battery Health and Charging on some models). Look at Maximum Capacity. iPhone batteries are designed to keep about 80 percent of their original capacity through hundreds of charge cycles, and most people start to notice the difference around or below that point. If iOS shows a service message, the battery is significantly degraded.
Open the Samsung Members app, go to Support, then Phone diagnostics, and run the battery status test. Other Android phones vary by maker, and some show battery health in the Battery section of Settings.
Not sure what you're looking at? Our diagnostics are free. Bring the phone in and we'll check it for you.
