Windows 10: Windows Search Indexer uses a lot of CPU while on battery, killing battery life

Hi,


I'm investigating an issue where the battery life on my Acer Predator 17 laptop has become ridiculously short.


One of the culprit is the Windows Search Indexer, that often is the top CPU consumer, even while running on battery:





Strangely enough, the indexer status reports that it should pause while running on battery:





Note that this is not a domain-joined machine, but a private computer, so I don't understand this message about an IT-set group policy.


How do I fix this?


There must be a way, even on a "private" computer, to tell the search indexer it should pause or at least throttle when running on battery.

The battery life

Hi boerab61,

Battery life varies from phone model to phone model, even when they're from the same OEM. For instance, the HTC Titan II has a different battery life than a HTC HD7. However, your particular battery life can be varied depending on several factors:

• Strength of your phone carrier signal. If you're in areas of low or terrible coverage, then your phone will consume more energy trying to maintain a connection with a cell tower.
• High usage of GPS can also drain the battery quickly because the GPS sensor consumes a lot of energy. By the way, if you are using GPS a lot, you can actually improve battery life by leaving WiFi on, as Windows Phone can quickly pull geolocation info from
  WiFi routers, even if you're not connected to them.
  

With that in mind, here's some suggestions to try to extend the life of your battery.

Reduce the load on your battery:

• 
  Decrease screen brightness.
  
• 
  Set Timeout duration on Backlight.
  
• 
  Set Auto-Off Timeout duration for 1 minute or less (device turns off).
  
• Throttle down your CPU speed.
• 
  Remove external devices (SD Cards, etc)
  

Turn off appropriate radios on your device:

• 
  Turn off Bluetooth transceiver when not in use.
  
• 
  Turn off WiFi transceiver when not in use (except when using GPS).
  
• 
  Turn off GPS receiver when not in use.
  
• 
  Turn off Cell transceiver when not in use.
  

Change the way you do things with your device:

• Minimize media playback use.
• Minimize use of e-mail and browsing.
• 
  Once in a while (every few weeks), drain battery until dead, then recharge 100%
  
• Keep a spare charger in your car and/or office.
  

Again, these are the ways you can consume battery life and yes, some are extreme but if you're serious about conserving your phone's battery, these are some great suggestions.

I hope this helps!

battery life


good evening,

has anyone noticed a shortened battery life with windows 10 or is around 2 hours good for a laptop battery to last without using the charger. I bought my dell e6410 with windows 7 ultimate on it but only used it for a little while that night before upgrading it to windows 10 pro so really don't know if it lost any battery life. it has the i5 2.67 processor and the backlit keyboard. also seems to be the original battery for it as well.
