Windows 10: Battery life bug since 22h2 update

Hello,In 2022, at the beginning of summer, I bought myself an ASUS Vivobook Pro 14x Oled. It is the N7400P model with an intel i5-11300H, an nvidia RTX 3050 capped at 40W, 16GB ram and an intel HBROEKNX0202AO optane ssd. Initially I installed windows 10 pro the 21h2 version. Right at the beginning I was really amazed by the battery life, on avarage I was getting around 6-7 hours of use, watching netflix, browsing even with a bit of chess played. After the 22h2 update, i noticed that my battery life significantly dropped, peaking at around 3 hours on 100% battery. Note that the battery design

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!
