at 830am I have 100% charge; almost 3.5 hrs later, doing nothing but surfing, (no hi-impact streaming)- down to 43%. Cycle count 395, 'condition normal.'
Does that sound 'bout right?
MacBook Pro 13″, macOS 11.6
Vaguely.
Somewhat: compared to weather reports from planet Earth.
When its rough, take shelter. Plug-in power adapter as needs.

Nothing you've mentioned has much to do with preserving runtime.
And the Mac cannot over-charge; automatic functions prevent that.
When on battery, what settings do you change to lower power usage?
Ration battery for longer life; use power adapter, as grid presents itself.
Certain tasks will be reduced to lower function when a portable runs
from battery power. This, to be expected; it is battery-assisted device.
Good luck & happy trails!🌞

That computer is a battery-CAPABLE device. It is not optimized as a battery-operated device.
Your computer performs best when connected to AC power. 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 even decline during stressful work.
When used only on battery, your computer has no extra cushion of power, and will perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)
Your MacBook Pro uses smart charging to charge in the optimum way, and only when necessary. Plugged in is Not necessarily actively charging. There are up to three micro-controllers cooperating on battery and charging issues.
In general, you should ALWAYS connect AC power when it is possible to do so, and only run on batteries (which will be somewhat slower) when no AC sources are at hand. Your Mac will NEVER over-charge.
