How do I know if my Samsung battery is draining too fast?

If your Samsung phone’s battery drains quickly, heats up during simple tasks, or slows down even with minimal app use, it could be a sign of a failing battery. Apps may crash or load slowly, especially when the battery is below 30%. You can check battery usage in Settings > Battery and device care > Battery. If one app is using an unusual amount of power, it might be a software issue, but if not, the battery is likely the cause.

Will battery replacement affect my phone’s warranty?

In most cases, replacing your battery with a third-party service like Mobile Klinik will not void your warranty, especially if the manufacturer’s warranty has expired. However, it’s always best to review your Samsung warranty terms. All Mobile Klinik repairs are backed by their own warranty for added peace of mind.

Yes. Mobile Klinik is a Samsung Authorized Repair Provider and uses Samsung OEM batteries and parts for all Canadian Samsung device repairs.

Yes. Most Samsung battery replacements are completed in under an hour, depending on the model and part availability. Walk-ins are welcome at Mobile Klinik stores across Canada, or you can book an appointment online for a time that suits you.

Common Samsung Battery Issues

Samsung phones are built to last—if yours isn’t, these battery issues could be the culprit.

Fast Battery Drain

Even when idle, your phone loses charge at an unusually high rate. This is often due to lithium-ion battery wear or degraded battery health, especially if you’ve had the device for over two years.

Random Restarts

Your Samsung might reboot out of nowhere—during calls, while gaming, or when browsing. Often, this isn’t a software issue, but a faulty battery that can no longer maintain consistent voltage output.

Swollen Battery

If the back of your Samsung phone looks or feels raised, or your case doesn’t fit quite right anymore, you may have a swollen battery. This is a serious issue that needs professional attention right away. Left untreated, it can damage internal parts or make the device unsafe to use.
