So, I just purchased the Lenovo Y520 about a month ago, and absolutely love it. It's portable, cool, and light. However, I have one MAJOR gripe. It's something that a lot of reviewers complained about, but I didn't know it was this bad. That's the extremely tiny battery in the laptop. When I say tiny, I mean 'it shouldn't have been allowed to be released with this small of a battery' tiny. To put it into perspective, I have Discord, Chrome (with 3 tabs opened), and Spotify opened with the battery saver mode (via control panel, along with the Windows 10 shortcut) on. At 80%, it says I have 35 minutes left. 35 minutes at nearly full charge with all power saving options turned on with only a couple apps opened. That, in my opinion, is rubbish. That brings me to my question. Would it be possible to purchase a larger battery online, and put it into the laptop, so I can get at least a few hours out of it before it dies?
