Battery Fault

Laptop battery draining fast

Fast battery drain is either an aged battery that has lost capacity, or software using more power than it should. Age-related capacity loss is normal after a few years and is fixed with a replacement; a software cause — background apps, full brightness, a process stuck awake — is a settings and clean-up fix. We run a battery-health check first to see which it is, so you don't replace a battery that's still healthy.

What you're seeing — and what it likely means

You see

Runtime is a fraction of what it used to be

Likely cause

Usually the battery has aged and lost capacity — a health check confirms it.

You see

Drains fast even when idle

Likely cause

Points more at software keeping the laptop awake or busy than the battery itself.

You see

Drops suddenly from a high percentage

Likely cause

Can indicate an ageing battery whose reported percentage no longer matches real capacity.

You see

Trackpad or case bulging

Likely cause

A swollen battery — stop using it and get it replaced promptly, as this is a safety issue.

What to do right now

Do

Note how long a full charge lasts now versus when the laptop was new.
Lower screen brightness and close heavy background apps to see if runtime improves.
Check whether the trackpad or base feels raised — a sign of a swollen battery.
Note whether it drains even when idle, which points more at software than the battery.

Don't

Don't keep using a swollen battery — it's a genuine safety risk and should be replaced promptly.
Don't rely on 'battery calibration' apps to fix genuine capacity loss; they can't restore worn cells.
Don't buy a random third-party battery before a health check confirms replacement is needed.

Can you keep using it? Will it get worse?

A battery that only loses capacity is safe to use on mains power while you arrange a replacement.

Capacity loss is gradual. The exception is a swollen battery, which should be treated as urgent for safety.

A battery-health check compares current capacity to the original design capacity — so we can tell you objectively whether it's the battery or software, before spending on a replacement.

How we diagnose fast battery drain

1Run a battery-health check to measure current capacity against the original.
2Review power draw from software, brightness, and background processes.
3Inspect for any swelling, which changes the recommendation to a prompt replacement.
4Tell you whether it's a battery replacement or a software fix before any work.

Difficulty: Straightforward — a health check plus either a battery swap or a software clean-up

Typical time: Often same-day for a battery replacement once the correct battery is on hand

What affects the cost

Battery vs software

A software power fix costs far less than a battery replacement — the health check decides which you need.

Battery availability for your model

Some batteries are common stock; others must be sourced for your exact model.

Genuine-grade battery

We fit correct-grade batteries rather than the cheapest cell, which affects the part cost.

We diagnose before we quote, so the exact price depends on what we actually find — not a guess.
