Venue 8 Pro - Rapid Battery Decline issue
Checking if others have this issue as well.
I have been having many issues with the Venue 8 Pro, and am about to receive my third replacement (fingers crossed).
However, I have noticed something on the two I have used so far. VERY RAPID BATTERY CAPACITY DECLINE.
Windows 8 has a nifty Battery Information feature that's hidden, but very very useful. I ran it, and noticed that after 4-5 charge cycles I have already lost 10% of my original battery capacity. This is an excessive;y rapid decline in battery health.
I wanted to see if others have this issue as well. If others have the same problem, that's a very serious issue.
Hoping to learn more, and if this is an issue others are having, I may return the Venue 8 Pro until Dell comes out with a hardware revision (not sure this is firmware fixable)
Here is how to run the Battery Report in Windows 8/8.1
1. Open a command prompt.
2. In the command prompt, copy and paste the command below, and press Enter.
powercfg /batteryreport

Just a heads up -- many users are having a problem with excessive battery drain on connected standby. This causes the device to lose battery rapidly overnight (sometimes to the tune of 40 or 50%). This is severely damaging to the longevity of the battery and may be what is reflected in your numbers. Mine has fallen to 96 after 4 cycles...

I posted this separately at: http://en.community.dell.com/support-forums/mobile-devices/f/4586/p/19538996/20497643.aspx#20497643
Specifically, the link below providing logging help and usage for Microsoft Windows Powercfg.exe may help some users diagnose battery usage and troubles.

Possible solution for some users...
I purchased a Dell Venue 8 Pro, and recently began experiencing unexpected battery drain. I had left the device fully charged, and returning 18 hours later it was completely discharged.
After some research, I realized I was suffering from having installed current Display Link software drivers (downloaded December 2013, version 7.5M0). I wanted to see if I could get large desktop going. Anyway, this is a known issue: http://www.displaylink.org/forum/showthread.php?t=62098
The symptom is that Intel's graphics processor remains at 100% usage even when the display is sleeping and off. I figured out how to generate a report for my own device by following the guidance at this page: http://www.hanselman.com/blog/PowerCfgTheHiddenEnergyAndBatteryToolForWindowsYoureNotUsing.aspx
Open the Command Prompt, and enter:
c:> powercfg.exe /sleepstudy
In the report that was generated, I clicked on one particularly draining Connect Standby session, and confirmed the "top offender" was Intel Graphics / fx at 100%.
Uninstalling the Display Link software has seemed to help.

Thanks for that info, that would definitely help with the battery drainage. However, the battery capacity is still rapidly diminishing. From some of the other comments I read it seems to be a prevalent issue. I notice some services that drain the battery, however it really shouldn't decline at the rate it is.

I just got a brand new Dell Venue 8 Pro. When I installed HWMonitor, my battery wear was at 10%. After a day, it was at 11%. Is my unit defective? Should I return it? I think I am going to, this is unacceptable. My laptop is over a year old and has a perfect battery with no wear.

DV8Pro is not the only device with this issue. My DV11Pro also shows only 96% after only few days and couple of charges. At this rate, the battery won't last more than 6 months.

I would not be surprised to see the DV11Pro and DV8Pro have similar battery technology and manufacturer. Yes, batteries degrade over time - however with these batteries it's nuts and well beyond the expected rate. Does anyone know if Dell reads these support forums?

Hi,
I had similar battery problem. 3% wear after 10 cycles. After long debate, they agreed to send a replacement. Now even the replacement one has similar problem and this time its worse. 3% wear after 3 cycles
Something is terribly wrong with the hardware. I havent drained battery beyond 15% and have been doing partial recharges. I dont know what to do this time. I seriously doubt if dell is ignoring this issue on purpose.

I know this thread is about the Venue 8, but I have a Venue 11 Pro and I've already lost 7% of the battery life on this and it's not even a month old.
I haven't really been tracking my battery usage, I just installed HWmonitor now. I am not sure what it started out with. I'll be keeping an eye on it to see how often it inches up. It stays plugged into a wall since I haven't been out and about after getting home from traveling over Christmas/New Years. Losing 7% in less than a month given my usage seems pretty terrible to begin with - at that rate in just 6 months the battery will be pure garbage.

Me too... DV8P, 1 month old, 10 charging cycles and 3,2% wear.
Thats not OK.
Any solution so far? Exchanging the device doesn't help from what I've read...
