Hi,
My macbook pro max m1 has 89% battery health and condition is "normal". Still, the laptops runs out of energy after about 4 hours working. I don't have many applications working, just running a powerpoint presentation or doing office work and emails.
Is there anything wrong with the battery, anything I can do to fix this or get more working time on the battery?
MacBook Pro 14″, macOS 15.7
Maybe, maybe not.

Installing Google and Microsoft products for example can reduce battery runtime by half. There may be other energy-intensive processes; identify them by selecting the %CPU column.

Nothing is wrong with the battery, the problem is in your assumptions.
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 could 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 maintain optimum battery charge levels under program control, and will NEVER over-charge. Connected to Power is NOT necessarily charging.
When you set it down in one place, or set it down for the night, Plug it in. Then you won’t CARE whether it would drain the battery.
If the cord is not long enough, Apple sells an accessory AC lead-in cord for about US$20, with local versions available in most areas. This is the US version:
