dell xps 15 l502x short battery life

i got my xps 15 yesterday and one of the leaflets said let the laptop connect to the ac adapter for at least 12 hours before using on battery. so i connected it to the adapter from 2pm yesterday to 8am this morning and when i took it off the battery read 95% 1hr15mins remaining. 10 mins later it read 87% 1hr 38mins remaining. is the battery life supposed to be this short? im using the 6cell battery

 

It depands on what your working on. If your encoding some Videos on Battery its discharing much quicker than idle.
Google for batterybar. Its an little toolbar that sits near the batteryicon and tells you some information about the battery, especially how much watts is being drained at the moment. If its something between 10~25W it is _normal_ (for idle) everything above shortens your batterylife (do the math)
When im surfing wlan, watchin a flash stream i´m draining about 15~17Watts with my 9 cell battery (90~wh) divide 90 by 17 and you get around 5,2 hours.

i was just browsing the internet, the intel turbo boost monitor showed that the cpu was between 2.7 and 2ghz though not sure why it needed to be that fast

 

The estimated battery life monitor will get more accurate as you use the computer. It needs to "learn" how you use your computer and how much power your computer uses. If you're worried about battery life, you need to go and change your power options in the control panel. Fine tuning in there will give you the balance of speed and battery life you want.

 

This is the part that ISN'T RIGHT. After that long of a charge, you should not immediately be at 95%. Did you take it off the charger and then boot or was it already on? If it was already on, then I would be concerned a little.

 

i connected the laptop to the charger, then turned the power on. atm my laptop says 2hr 18mins on 70% charge but the time changes a lot and my power settings are on balanced, it also says 95%, not charging, why would it not charge?

 

There is a button or setting that will disable charging. Never messed with it so I don't know where it is or how to change it. Maybe someone will chime in and say.

I also agree that after that long of a charge, you should be at 100%. It only takes a couple of hours on a dead battery to completely charge mine up and I'm using it at the same time.

When I got mine I just turned it on. Didn't even connect it to a/c for the first time until a couple hours later when it got down to 10%.

If you keep charging it, and it never goes above 95%, I'd call dell and ask for a new battery.

 

same problem here. my xps 15 is 3 months old but the batt backup has died down to 1hr 20 mins or so at 99% with 6 cell battery and balanced mode. i called dell for replacement and they told me that they'll replace mine with a refurbrished battery instead of new one.....

 

and the turbo booster of mine laptop also shows 2-2.80ghz unecessarily. even when laptop is idle

 

My XPS 15 lasts 4-5 Hrs on A Single charge.. Yeah.. Its on a 6-Cell...
Total Charging time is about 2 hrs.. just calibrate it once..
Run it down completely and then charge to full before using..
Also, use it on battery whenever possible.. That helped me alot

 

^ This is a good thing to do. I did this to my laptop too.

Also, you can change your power settings by clicking on the battery icon. On battery, I set my CPU limit to 60%. I never do anything demanding on-the-go so it works for me.

 

Also remember that if you have the brightness at its max it will drain a lot of battery.

 

Download and install cpuid it will tell you the battery design capacity, full charge capacity and current capacity in mWh's. It also shows the current charge level and the wear levels in percent...mines at 2 percent which is good, a worn out battery will read a lot higher.
