I have a habbit of using the battery down to 15% than plug in to recharge until full to have a good battery cycle, but everytime I plug in the system suddenly to perform extremly slow, I can notice the CPU ramping up to 40 ~ 50% just doing easy task like browsing using Chrome, this normally only takes around 5%.
This last for around 10 minutes or if I restart the system and everything is fine. So I'm not sure if it's because of the power % is causing some limit to performance or it's because the plug in of power source, but I tried to plug in and out multiple times and nothing really happens, so I'm assuming some thing happens when the battery level is under certain percentage and when plugged in under that cetain % something must be happening in the background. From my observation, I'm assuming this happens when the battery level is under 35 ~ 38%.
Sorry if I'm not following any community rules it's first time posting here and please let me know if you need and information of my system I'll provide it asap.
