Laptop Battery Not Holding Charge
The laptop charges to 100% without issue, but the battery drains far faster than it used to, or the estimated time remaining drops rapidly under normal use.
Quick answer: A battery that charges normally but drains much faster than it used to is almost always simple age-related wear — laptop batteries lose capacity over time and typically need replacing every few years of regular use. This is different from a charging fault, where the laptop won't charge at all.
Likely causes
- Normal battery wear — most laptop batteries noticeably degrade after two to four years of regular use
- Background programs or browser tabs consuming more power than expected
- Display brightness or power settings that haven't been adjusted for battery-saving
- In rarer cases, a battery fault causing it to report capacity incorrectly
What you can safely check yourself
- Check Windows' built-in battery report (powercfg /batteryreport via Command Prompt) to compare current capacity against the original design capacity
- Lower screen brightness and check what's running in the background during normal use
- Note whether the drain is gradual (suggests wear) or sudden (worth investigating further)
When it needs a proper look
If the battery report shows significantly reduced capacity, or the drain is sudden rather than gradual, a battery replacement is usually the straightforward fix.
