Frustrating Battery performance & Screen time on new macbook m4 pro

Not i am not running any major which will utilized CPU or GPU as barely in 1 week usage I have heard any fan opration noise.

Did you check Activity Monitor? On my M4 Pro MBP with only one application (Activity Monitor) running, there are over 800 processes running on the CPU. The fans aren't a good indicator, either. I can batch convert RAW images (CPU/GPU intensive) and the fans remain off. I only hear them spin up during a long video transcode.

Chrome is particularly resource-intensive because it installs Google which renders your Mac a full time information-harvesting and -uploading "bot" for Google's purposes. Those processes can't be turned off or disabled, even if you quit the Chrome browser. Even without knowing what else is installed on that Mac it is all but assured a multitude of Google's automatically updating virus-like processes are causing your Mac to work overtime.

Get rid of it. No one needs Chrome. Follow these removal instructions.

Ya I read that what u are telling is they are telling upto 22 hrs

What u mean is that is max but you can't expect always it will give 22 hrs; is that u are referring

But what i am telling on average case it should have given atleast 12-15 hrs? Is that also not possible?

No. It depends on what third party software you have installed on the system. Even if you don't have any third party apps installed, you may still have some Apple features or services enabled which may be using enough energy to cause the battery to drain more quickly.

I find some days my M1 & M2 laptops may go the whole day with lots of battery charge left over, but on another day I may only get 5 or 6 hours of usage on the battery. Nothing significant has changed on my laptops other than perhaps having a different number of apps and/or browser tabs/windows open.

I don't think so it is

expectation problem ; as i am asking for what value was promised.

Apple never made any promises. They gave you the test results under very idea & favorable testing conditions. It would not surprise me that they may have turned off various macOS features in order to achieve those results....very common with hardware vendors performing benchmarks for advertising & marketing purposes.

You can always hire a lawyer to pursue any perceived promises you believe Apple made.

And yes the the technician is ready to replace the battery if I am not satisfied that's what their promise is.

That is an option, but more than likely you will see the same results. There is always a slight chance you do have a defective battery. It is rare for a brand new Apple battery to have issues, but it cannot be completely ruled out since even Apple's service diagnostics and the macOS battery condition status cannot actually detect many battery related failures.

But I am asking , for new device can this problem can exist?

I don't know anything about any consumer laws in India so I don't know what your legal options are. That is something you need to ask a lawyer. My guess is another new laptop will have the same results if you restore it with the same configuration setup as your current laptop. Have you actually tested an identical laptop in an Apple Store to compare results keeping in mind the laptop in the Apple store is unlikely to have any third party software installed and is unlikely to have iCloud & other services enabled which could affect performance.

You are posting Marketing information, used to suggest COMPARATIVE battery performance, NOT a guarantee of performance under any conditions. The footnotes on the original source pages make that much more clear.

To attain those numbers you would have to replicate that laboratory experiment EXACTLY, using Safari, and NOT have any google extensions of any description loaded on your Mac, and absolutely positively NOT be using Chrome, the Mac's worst resource-hungry nightmare.

a side note re AI:

AI can provide the AVERAGE of all answers anyone has posted on the internet. AI does not necessarily provide Authoritative information, only Typical information. That information could be very wise, or it could be published by folks who cannot distinguish down from up. AI does not know (or care)

To judge accuracy, you need to see the sources, and decide whether they are authoritative, or even applicable. And You MUST rule out AI hallucinations.

Did you even READ footnotes 4 and 5 that show on that information you posted?

Those results were obtained under tightly-controlled laboratory conditions, and NOT using Chrome.

You don't seem to be hearing what a mess Chrome (and the google extensions loaded with it) makes of your Mac's performance.

<< he is getting 5 hrs on my machine; don't you think then there is issue with hardware?>>

No, I do not think there is any hardware problem, only an expectations problem.

And if there were such a problem, why has your Apple-Authorized technician not offered to swap out hardware under warranty to fix it?

Sounds like something is running in the background that is using a lot of resources. What processes are running in Activity Monitor?

Activity Monitor User Guide for Mac - Apple Support

That computer is a battery-CAPABLE device. It is not optimized as a battery-operated device. (It is NOT an iPhone.)

Your computer performs best when connected to AC power, such as the power adapter. It can use the full output of the Power Adapter AND when doing especially challenging work will also freely "borrow" power from the battery. In some cases, even with the power adapter connected, the charged state may decline during very stressful work.

When used only on battery, your computer has no extra cushion of power, and may perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)

In general, you should ALWAYS connect a power source when it is possible to do so, and only run on batteries (which could be somewhat slower) when no power sources are at hand. Modern Macs maintains optimum battery charge levels under program control, and will NEVER over-charge. Activate Battery Health Management and do not spend another moment of your time thinking about charging.

Google Chrome is by far the biggest resource hog of any Mac software that is not obvious malware. if you insist on using Chrome, count on very short battery life every day.

On my 16" M4 Pro MBP, my system currently shows 100% battery health and an estimated 14 hour run time from the battery at 80% charge. Multiple apps open (but I don't use Chrome).
