I upgraded from my SD S10 to Note 20 Ultra Dual Sim Exynos couple weeks ago and Im getting dismal battery performance with about 2h35 to 3h15 of SoT, and I noticed the standby drain is pretty bad.
Before judging me: Yes I am fully aware of the whole Exynos 990 v Snapdragon thing, but because I couldnt get my hand on a dual sim N20U with SD so I settled with the exynos version, which I have seen people claiming getting about 5 hours of SoT vs. over 6 hours of SoT on the SD, and I would totally happy with 5 hr considering my usage. But barely getting over 3 hours of SoT is just plain stupid considering the price I paid for it.
I love everything else on the N20U, but having to carry around a power bank all the time is really annoying. Is anyone experiencing the same issue and any luck on fixing this? I am not sure if it is a software issue.
P/S: I attached a couple of screenshots for Battery Usage and Gsam Battery report. I did just reset my phone yesterday to see if the performance improves, no luck. I also did all the battery optimization settings + limit all background usage on all unnecessary app, including facebook and other social media apps..
There's definitely something wrong here. I too have the Exynos and the minimum SoT on WiFi is 6.5 hours (i've achieved 7.5 hours yesterday for example). On 4G this decrease to 5 or 5.5.
The only thing that i have configured is putting all the apps that i don't need notifications into deep sleep.
