Originally posted here: We know Dell claims 17 hrs battery life on XPS 9550 and that is something of bullsh*t. Early this year I was looking for a replacement for my 4-year-old HP Elitebook 8560p. The main concerns are battery life and portability and if you have used an 8560p you know why. After watching some reviews online and some googling, I bought an XPS 9550.

The main specs are: i7-6700HQ 16GB RAM 512GB SDD FHD display (mainly for the purpose of longer battery life) 84 mWh battery I bought it in March 2016 and the battery wear level was at 4% out of the box. It was frustrating that I never got more than 6 hrs battery life. After 6 months the battery wear level rose to 19.1% and battery life was even worse. I called Dell in China hoping to get a battery replacement, but they told me they could replace it for free ONLY when the wear level reaches more than 20% in the first year. So I decided to solve this problem on my own (of course with help of the Internet). Battery calibration The first thing I did was calibrating the battery (full charge and discharge). I know it is harmful to do it too often but I decided to give it a try to save my life.

The method is: • 1. Fully charge the battery • 2. Let it drain from 100% to 5%. When it reaches 5%, Windows hibernates. Boot it to BIOS and let it drain from 5% to 0%. The laptop will shut down at 0%. Charge it fully.

One interesting thing is that the battery level stayed at 7% for like more than half an hour. I guess this is where the calibration process really works. After doing that, the battery wear level decreased from 19.1% to 7.4%. I didn't expect this much improvement to be honest. Reducing background services and apps Then I disabled some unnecessary background services and start-on-boot apps such as Evernote clipper, Google/Adobe/Itunes/Office update services/scheduled tasks, Maxx Audio service(Dell Audio) and so on. You can use a fantastic tool called 'Autorun' to do this job: I still have some start-on-boot apps enabled, such as Ditto, f.lux, some AHK scripts and Throttlestop. Because I rely on them very much and they don't seem to consume much power.

Undervolting I use ThrottleStop (version 8.30) to undervote the CPU/cache to -179.7mv. This reduces much much heat/temperature and saves quite some battery. You should do some stress tests, such as prime95, to make sure it is stable. You don't want any BSODs or sudden reboots. Windows power plans When running on battery, I use the 'power saver' plan and enabled 'battery saver' option.
