Just installed a replacement battery for my XPS 13 9350 (2016). How long should my new replacement battery last on a full charge? My battery indicator shows about 3 hours for a full charge.
Is this a good question?

First off you do need to let the system learn the new battery as the BMC logic will still think it has the older battery present. Run the system down to 10% then recharge to 90% then repeat one more time that should do it.
As far as what the battery can offer you for performance, that’s a bit tricky! There are too many factors to give you a value. It should last about the same as what your original battery offered.
The issues you face here is OS your system is running and what extensions you’ve loaded, then the type of apps or games as they will also effect run time. Then are you using your system just above zero C outside or running in 30 C under the blistering sun.

Thanks for the response. Cycled battery as suggested by ifixit (seller). It still only reads about a 3hr charge, about 1/3 of the original battery would give.
Try uninstalling the Microsoft ACPI- Compliant control method battery driver in Device Manager, then restart the laptop in the normal manner to let Windows reinstall them again and then check the battery.
Go to Device manager → Battery → right click on the Microsoft ACPI- Compliant control method battery entry → Uninstall and follow the prompts.
To get to Device Manager press the Win key and the x key (both together) and click on the Device Manager link.
Not sure if you've done this but if not, create a battery report to check the condition of the battery.
When you have the report, compare the Design Capacity value versus the Full Charge Capacity value as shown by the report..
For a good, new battery, they should be nearly the same value.
You can work out as a percentage the condition of the battery by using the formula Full Charge Capacity value x 100 ÷ Design Capacity value.
