For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced within 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.
Hey guys! I just purchased the dell g15 se (RTX 3060, i7-12700H, QHD 240Hz, 85 WHR battery). I am only getting a battery life of around = 1) Very conservative use- 2-2:30 hours on doing my online classes at about 20% brightness on power efficiency mode. No apps running in the background and zero devices connected. All the drivers have been updated. 2) compression/gaming makes the laptop last for an hour at max. Tried all diagnostics and generated a battery report which also shows the expected battery life to be around 2:30 hours. Dell Tech support says that the battery is working according to the design. Whereas the sales team says the battery should last for around 5-6 hours during light use. This is particularly a very bad sign for Me. As the power brick is an absolutely colossal 240 WHR. And there is no charging through Thunderbolt in this laptop. Any suggestions? Should I do a fresh Windows install and not update the drivers to see if they are messing with the hardware?
