XPS 9570 Battery Drain During Sleep
XPS 15 9570
Dear Community,
For my first four years, I stored the device overnight in sleep mode with about 10% battery drain. In the last 3 months, this increased progressively until it now drains 60%. According to the threads and FAQs I have read this is standard behavior, and maybe I was lucky to use it for that long without greater battery drain overnight. My question is should I shut the computer down overnight to avoid killing the battery through so many charge cycles?
Separately, support here says I can get a replacement battery for $70. This looks a lot cheaper than this parts supplier. I am wondering if I should get one just in case. Would like to get a few more years of use from this if possible.
Thanks,
Chris

If the battery is original and four years old, it has exceeded a normal lifespan. That said, if "support here" means Dell, I don't think you'll find an OEM battery for $70 -- unless it's third-party, in which case be sure your supplier is reliable.

The battery replacement quote was from official Dell Support in Japan. They had been working with me on the drain issue for a while trying different software fixes before finally saying they would need to take the computer and check it for a week to determine the issue (which I declined).

If you are still noticing the Battery Drains in Sleep Mode on your Laptop, the problem might be due to the poor health of the battery installed on your Laptop. You can confirm this by generating a Battery Health Report on your computer and checking the current health status of the battery installed on your laptop.

Thanks, the health report showed a 71,113 mWh full charge capacity vs 97,003 mWh design capacity. It was above 80,000 less than a year ago, so I guess this explains the difference in performance. Still wondering if I should go ahead and get the replacement battery. I assume they won't be getting cheaper or more available in the coming years.
Is the replacement process simple and safe enough for me to do on my own? I have built a desktop PC and done some basic work in Mac laptops but not this one so far.
Thanks,
Chris
