best battery - better battery - better performance - best performance

i use basic stuff only like typing, youtube 720 (lag sometime) and maybank. using better performance at the moment. too much?

battery still kaw2 12hr 10% bright on my 2023 lenovo d330 10''

ya'll use which? got difference?

For me. laptop with more than 8 hrs of practical use is good enough dy. Meaning at end of 8 hrs if still got more than 30% battery left. Usage of office, light programming, some rendering etc etc etc. If there is such lightweight laptop that is and wallet friendly.

The Lenovo D330 is running on Intel Dual-Core... you cannot expect much from kind of CPU.

You can try upgrade to 16GB RAM & faster SSD for some performance improvement, but still don't expect it to be very significant due to your CPU is only 2-Cores.

But take note that if you do the upgrade, the additional hardware means additional power consumption = less battery standby time.

It all depends, whether you want performance or you want battery life.

You're expected to have best battery selection if you've not connected a power source for xx hours.

And with power source, swap to best performance.

That's how it should be honestly.
