For users who keep their laptop plugged in most of the time, you can use the Dell Power Manager software to limit the charging threshold to between 55% and 80%. Alternatively, in the BIOS “Power” menu, locate the “Primary Battery Charge Configuration” option and set it to “Primarily AC Use” or another custom mode.
Practice shallow charging and discharging; avoid overcharging or deep discharging: Unlike older battery types, lithium batteries do not suffer from the “memory effect”; instead, they are quite sensitive, and deep discharge (letting the charge drop near 0%) is a major “no-no.”

Everyone knows this: Your own laptop does its job well, but over time, your laptop’s battery life shortens. Sometimes it’s time to replace your Dell XPS 9360 battery. This is the case with our Dell XPS 9360, and since it’s such a popular model , we’ve created a battery replacement guide for you.

Dell batteries are now causing problems with all-in-one PCs. According to Dell Power Manager diagnostics, the capacity is only about 60% of the actual maximum capacity. Specifically, that leaves 39 watt hours of the actual 60 watt hours. So we bought a replacement Dell laptop battery from Green Cell for around €50. Original Dell batteries cost at least € 110. Below we will show you how the exchange works. 

To replace the  Dell XPS 13 9343 and 9350 battery , you will need a Torx screwdriver (T5), a Phillips screwdriver (#0), a spatula, and a guitar pick. We’ve got all the necessary tools ready in the iFixit toolkit. Start by flipping the XPS 13 over and removing the eight external Torx screws. Also fold in the tab with the XPS logo and remove the Phillips screws there. You can then remove the case back with a guitar pick. Alternatively, you can use another flat object, as long as it’s not a sharp metal object that could scratch your case. 

Please note that if you replace your Dell  laptop battery , you will lose any warranty claim. You are responsible for any damage that occurs during or after repairs. Allround-PC assumes no responsibility for any damage or loss of data. 

Step by step instructionsRemove the eight Torx screws and one Phillips screw locatedRemove the three Phillips screws marked M2x2 and one screw marked M1.6×4. Use a spatula to carefully loosen the three cables on the side of the Remove laptop batteryInsert new battery, tighten and reassemble. New batteries should first be discharged to about five percent and then fully charged.

This needs to be repeated at least three times. In our case, we noticed a significant increase in the  laptop’s battery  life after the replacement All in all, it was very easy to change, although we later had to reattach the speaker cable (to the right of the battery) because the speaker cable had come loose when the glued cable came loose. It’s definitely worth buying a new  Dell laptop battery.
