I use a fast charger since day 1 (3 years). I had no issue with loading at all untill the update.
I tried to uninstall the last updates (Google and Google Home), I'm not sure if it changed anything.
HEY EVERY ONE EXPIREANCE THIS PROBLEM ALL U DO CLEAR CACHE PHONE DEN BACK UP EVERYTHING WEN BACKED UP DO SOFT RESET ERASE ALL SEND IT FACTORY DEFAULT DEN WEN DONE RESET PHONE DONT EXPET OCTOBER UPDATE OK TRY THIS SEE WORKS IT SHOULD WORK
I have the same problem with my exynos Galaxy S10+ since I installed the Dutch November security patch yesterday.
Since then my phone doesn't go into deep sleep mode anymore at all. With as result it drains 10% overnight with airplane mode on and Wi-Fi disabled, instead of 1% before the update.
It also shows a much higher usage of android system under battery usage in the settings app.
I have had the S10e since April 7th, 2019 and it's been sort of ok but recently the battery has been depleting rapidly, it's gotten to the point where if using it normally for a day, (just a few minutes of games and texting people, along with a little bit of social media) my phone gets depleted down to almost 0% after 4-5 hours. Like how does this phone have almost the same battery as an S10 and even an iPhone and STILL manage to kill the battery 2-3 times as quick?!
