Battery Drains Rapidly While MacBook is Shut Down — Replaced at Apple Authorized Service Provider, Denied Warranty Support

Hi everyone,

I’m dealing with an ongoing battery issue and would appreciate insight, shared experiences, or advice on how to escalate this with Apple properly.

Device Info:

• MacBook Pro (1.4 GHz Quad-Core Intel Core i5)
• Battery replaced at London Drugs, an Apple Authorized Service Provider (AASP)
• macOS fully updated; SMC and PRAM resets completed

Issue:

My MacBook’s battery is draining rapidly while completely shut down — not in sleep or hibernate, but fully powered off. This has been happening since the battery was replaced.

Apple Support recommended a macOS reinstall, which I completed, but the issue persisted with no improvement.

Battery Drain Logs (While Powered Off):

Before OS Reinstall:

• 05/12 18:43 – 100%
• 05/13 10:28 – 98%
• 05/14 10:47 – 88%
• 05/15 13:28 – 78%
• 05/16 10:48 – 69%
• → 31% drop over ~93 hours (~0.33% per hour)

After OS Reinstall:

• 05/17 14:12 – 100%
• 05/18 14:10 – 90%
• 05/19 10:56 – 81%
• 05/20 09:23 – 71%
• 05/21 09:37 – 59%
• 05/22 10:38 – 47%
• 05/22 13:01 – 38%
• → 62% drop over ~119 hours (~0.52% per hour)
• Even a 9% drop in just 2.4 hours was observed.

Technical Notes:

• Battery condition: “Normal”
• Hibernate mode is confirmed as 25 (full shutdown behavior)
• This is not a software issue, but rather a defective or poor-quality battery

Interaction with Apple Support:

I contacted Apple Tier 2 Support, who acknowledged the battery warranty is 90 days.

I explained that during those 90 days, I had visited London Drugs multiple times to report the issue, since they were the Apple Authorized Service Provider that installed the battery.

However, the Tier 2 advisor told me that I was required to contact Apple Support directly, even though no one at London Drugs informed me of this requirement.

He said he had checked with his supervisor and there was “nothing more they could do,” effectively leaving me with no support — despite having acted in good faith and reporting the issue in time.

My Ask:

• Has anyone else had a similar experience — being told to contact Apple after working with an AASP, only to be denied service?
• Shouldn’t an AASP visit within the warranty period count as a valid support contact?
• How can I escalate this to Apple Customer Relations or request a case review?

This feels like a breakdown in communication between Apple and its service network, and I hope someone has advice on how to resolve it.

Thank you!
