Frequently Asked Questions
Quick answers about the phone health check.
Can I check my phone’s health online?
Yes. This tool reads what your browser exposes about battery, memory and storage, and runs a real memory-speed test. It needs no app and no root access.
Does it show exact battery health?
No. Websites cannot read battery capacity or charge cycles. You get charge level and status. For true battery health, use your phone’s own Battery or Samsung Members settings.
Why does my RAM show 8 GB or more?
Browsers cap the reported RAM at 8 GB for privacy, so phones with 12 GB or 16 GB all show “8 GB or more”.
Is the storage number exact?
It is an estimate. Browsers do not reveal exact storage, so the total is based on the space your browser is allowed to use. Check Settings → Storage for exact figures.
Is it safe for my privacy?
Yes. All tests run inside your browser. Nothing is uploaded, and no IP address, location, contacts or files are collected.
Which phones and browsers work best?
Samsung Galaxy and other Android phones with Chrome, Edge or Samsung Internet give the most data. iPhone Safari hides battery and model details.

Quick Tips for a Healthier Phone
What to do after you read your report.
Low RAM score? Close background apps and restart your phone, then run the test again to compare.
Keep your battery between 20% and 80% when you can. Frequent full drains and charges wear it out faster.
Storage nearly full? Clear cache, remove unused apps and move photos to the cloud to keep your phone smooth.
A hot phone slows itself down. Run the test when the phone is cool for the most reliable score.
Keep One UI and your apps updated. Updates often fix battery drain and memory leaks.
For exact battery health on a Galaxy, open Samsung Members and run the built-in diagnostics.
