I have a Dell XPS 15 that I've been using for about 3-4 years, and lately, the battery life has been terrible, lasting under an hour even with my usual software. I've tried all the common tricks to save battery life: enabling battery saver mode, reducing performance settings, cleaning up unnecessary files, and keeping the brightness low.
Frustrated with the short lifespan, I recently replaced the battery, cleaned the fans, and applied new thermal paste. While the battery life improved a bit, I'm only getting around 2 to 2.5 hours now. I need this laptop for school and hope it lasts at least another 3 years without breaking the bank on repairs. Is there anything more I can do, or is this the best I can expect?
Note: You can check the battery report images linked here: [Battery Report](https://imgur.com/gallery/battery-report-fdIGg2y). The new battery was installed on 7/29, so previous reports are from the old one.

Where did you buy the new battery? It’s important to use a genuine Dell battery for the best results. You might also want to run a detailed battery report using the instructions in this Microsoft guide to see if there are underlying issues with charging or capacity.
Since you mentioned you got the battery from Dell, that's good. Make sure to check the settings that might still be affecting battery life, like background apps still running or any power-draining processes. Keeping your software updated can also help with battery management.
