Hi

I bought this used Razer Blade 15 Base 2020 on may this year, apart from a few scratches it was practically new it even still had the stickers.

Recently I’ve been bringing it to class giving me an estimated 4 hours of battery life since it would drop to about 50% from a full charge for since my class lasts 2 hours,  this morning i took it to class again on a full charge and by the end the battery had drained to 6% i started using battery saver recently and even messed with the power plan settings and now the battery life has halved i didn’t even have it on during the entire class i had it on for maybe an hour at most what could be causing this drain?

I always have it on half brightness and no RGB when i bring it outside

I noticed the fans were on during the entire class which could be what drained the battery but i was just sitting idle using Visual Studio as usual.

Here’s a summary

• Started bringing it to class 
• Lasts 4 hours normally
• Recently messed with the Power Plan for more Battery Life and started using power saver
• Now Lasts an hour at best

I’m also wondering if i can upgrade the battery on the blade if that’s an option
