Inspiron 16 Plus 7630, formal complaint, abnormal battery degradation 51%

You can complain if you wish, but that's normal battery degradation -- lithium ion batteries are usually good for about three years or 1000 charge cycles, so both of those are in the near future.  It's simple, ordinary life cycle data for the battery.

Dell Laptop Battery Warranty Support

Standard warranty: 1 year for most laptop batteries.
Extended warranty: Optional 3-year coverage (must purchase at time of laptop order).

You did not purchase the Optional 3-year battery coverage at time of laptop order =

You will need to purchase a battery from a seller in your region. The Dell part numbers are listed below =

@DELL-ChrisM2​

I paid €1,400 for a Dell Inspiron 16 Plus 7630. After 32 months, the battery has lost 51% of its original capacity — confirmed by Dell's own SupportAssist diagnostics with an official WARNING result.

Dell's response: "Battery is a consumable part, covered for 1 year only."

For comparison: my wife's 8-year-old MacBook battery still holds 3x more charge than my 2.5-year-old Dell.

Dell ran their own diagnostics and confirmed the battery is failing — yet refused a goodwill replacement, citing warranty expiry.

713 charge cycles. 32 months. 51% capacity loss. €1,400 laptop.

Make your own conclusions before buying Dell.

Thank you for your response.

I note that Dell acknowledges the technical data but considers 51% capacity loss at 713 cycles as "expected wear." I respectfully disagree, and I want to place the following on record:

1. 713 cycles in 32 months is approximately 22 cycles per month — this is consistent with normal daily laptop use, not abusive usage.
2. Industry standard (including Apple, Lenovo, and Dell's own documentation) states that a healthy lithium-ion battery should retain at least 80% capacity after 1000 cycles. My battery is at 49% after 713 cycles — well below this threshold.
3. Dell's own SupportAssist issued a WARNING — not a notice, not an advisory — at only 713 cycles. If this is "expected wear," why does Dell's own tool flag it as a problem?

I am closing this thread but will be sharing my experience and this correspondence publicly, including on review platforms, and will be filing a complaint with Verbraucherzentrale Berlin.

I hope Dell reconsiders its approach to battery quality and warranty coverage for future customers.

Hi DzmirtyAnts,

Just wanted to clarify position that you listed here regarding public statements from multiple companies. Apple is the only one I found that actually gives a public statement on official battery cycles. I want again to reference that you are comparing different design and firmware among vendors, that is not likely to be considered equivalent. 

Our tools will give an alert when the battery reaches either fair or poor health, that is the message you're getting on Support Assist. This is to alert the user to action that could prevent affects to usage or data loss while using the system.

Apple matches what you said here: Determine battery cycle count for Mac laptops - Apple Support

But Dell and Lenovo do not, calling out degradation as soon as 12 to 18 months: Battery Q&A - Lenovo Support US, Check Laptop Battery Health: Test Battery Condition on Windows | Dell US 

Re: 713 charge cycles. 32 months. 51% capacity loss. €1,400 laptop.  Make your own conclusions before buying Dell.

Oh NO, NO, NO !  When a battery goes bad, you replace the battery, not throwing away a €1,400 laptop.

A new battery for your laptop is €78.99 excluding VAT.  https://www.dell.com/de-de/shop/dell-lithium-ionen-ersatzakku-mit-6-zellen-und-86-wh-f%C3%BCr-ausgew%C3%A4hlte-laptops/apd/cpl-m59jh/pc-zubeh%C3%B6r

@DELL-Joey​

Thank you for the clarification — that is a fair point regarding the cycle count comparison, and I appreciate the correction.

However, the core issue remains unchanged: Dell's own battery health documentation states that capacity loss is expected "after 18 to 24 months for most users." My battery was manufactured in September 2023 — that is exactly within this window — and has already lost 51% of its capacity, not the typical 20-30% one would expect at this stage.

The question is not whether batteries degrade — they do. The question is whether 51% capacity loss falls within normal degradation parameters for a €1,400 laptop used for 32 months. I would argue it does not, and Dell's own SupportAssist agrees by issuing a WARNING.

I accept that Dell's position is final on this matter. I will be sharing this correspondence with Verbraucherzentrale Berlin and publishing my experience for other consumers to make informed decisions.

Thank you for engaging with my case.

Stuff happens — nobody is disputing that. Batteries degrade, components fail. That's life.

But when a major international brand with a strong reputation sees a loyal customer coming with hard evidence of a defective component — Dell's own diagnostic tool issuing a WARNING at 32 months, 51% capacity loss — and chooses to hide behind a 1-year battery warranty instead of doing the right thing, that's a different story.

It's not about €79. It's about whether a company stands behind its products and its customers when it matters. In this case, Dell chose not to.

That's worth knowing before you buy.

@DzmitryAnts , your case was presented and the matter was concluded with the responses from Dell.

My post simply pointed out a €79 battery replacement is not the same as implying €1,400 laptop value loss of use.  The difference in value number does have serious impact on someone mental being, anger feeling from unjust treatment, and causing all the effort for recovery from losses.  Hence, the practical solution of battery replacement with link provided and saving yourself from lot of headache and time consuming effort to save that €79.

Opinions differ and I think misinformation was also factor in this case,  Inspiron is not Dell premium product line and their batteries were designed for 300 to 500 cycles usage.  Some are better now but do not compare to Apple's unless it's from XPS or Precision product line.

According to the consumer sales and guarantees here https://commission.europa.eu/law/law-topic/consumer-protection-law/consumer-contract-law/consumer-sales-and-guarantees_en

if your laptop battery stops working prematurely due to a manufacturing flaw within your 1-year statutory warranty, it is legally covered. If the battery's lifespan has simply naturally run its course after years of intensive daily usage, it is considered normal wear-and-tear and is not covered.  

The application to batteries by German consumer courts distinguish between a Sachmangel (defect present at delivery) and Verschleiß (normal wear and tear).  It considers defect only if a laptop battery fails shortly after purchase (often evaluated within the statutory 1-year warranty period),
