[Samsung Galaxy S10+ Questions & Answers] KavaBreskva:
Bought this phone 4 days ago on friday. S10plus exynos 128gb, dual sim, but i only use one sim. Android 10 and ONE UI 2.0.

Friday was spent to set up the device. I used smartswitch. Saturday, i fiddled with the device. Battery wasnt that great tbh. Sunday i read some guides and i factory reset it, backuping only messages and photos (contacts are from google). All apps were reinstalled manually.

What got me worried was, i set an alarm for monday at 7.30. When it rang i unplugged the phone and kept snoozing it for another hour. When i finally woke up at 8.30 it was on 94%. 6% from snoozing it?? Come on...

So i reset all three settings (accessibility, network and setting) and cleared cache in recovery mode. Still i was at 6% at 18.00 and i wasnt done with stuff, but i had to go home to recharge... SOT at 6% was 4hrs 50 minutes. I used gmaps navigation for 2hrs and that was the only time i had location turned on.

So today i did some more tweaks and my setup is as follows:

LTE ON all day

Wifi maybe turned on once or twice for few minutes

AOD on tap

Lift to wake OFF

Dolby atmos ON

Sync off

Location off

Bluetooth off

Dark mode ON

Power mode is on Optimized

Adaptive power saving is ON

Adaptive battery is on (altho idk how much it worked in this two days since factory reset)

Bixby is ON and it can be summoned with locked screen

Google assistant is off, but i can "hey, google" when im on home screen.

Screen brightness was most of the time at around 50-60%

Keyboard vibrations ON

Medium resolution

Its 17. 00 right now and im on 10%

SOT is 7hrs 30min but with 9hrs away from charger. I had a day off, so i decided to use it extensively to test the battery.

I have seen peoples results and theyre much better. Like:

-15% left, 21hrs since charged and 7hrs 30min SOT

-15.5hrs from battery, 7hrs sot with 3hrs of youtube and still 10% left

-1day on battery, 7hrs SOT with 2 hrs spent on instagram

-12hrs on battery, 7hrs SOT and 50% left

-7hrs on battery 6hrs 50minutes SOT with 64% left

-the most impressive 1day 12hrs on battery, 13hrs SOT with 4hrs of youtube and 4hours of spotify.

I know it depends on user and his usage, but the results of others are just too much better than mine and i cannot neglect that. And some are using BT, Location and SYNC all day ON with great SOT and standby and come home at night and dont worry about battery. I want it all on too, but mine would probably be dead by 14.00.

I was deciding between S10+ and P30Pro. Huwaei because i know their battery is superb. But samsungs stereo and system convinced me to stay loyal to samsung, and i thought that the battery will be improved and good with a 4100 unit.. But i guess i was wrong. I previously had s7edge and battery wasnt that great either, but i decided not to act on it and somehow got through with it for 3 years with multiple chargers thru the day. I thought this will be a very noticeable upgrade, but its not... And honestly, i dislike night mode and i love AOD always ON, always had it on on 7edge, but im afraid to use AOD and day mode on 10+ cuz of battery. It should be okay from the box for the price it costs. I thought with this big battery i will be able to have Location, BT, Sync, Data Always turned on and get through the day no problem. But apparently not. And I know its possible with huawei and i chose s10+ cuz i thought now it will be possible and i like its UI more.. But well.. Im disappointed..

Can anyone advise me what to do? Is my battery faulty? Should i exchange for a new one? As i said with s7edge i didnt go complain to samsung, but this is second phone with same problem and even more expensive. I feel it should be better. I expected at least 8hrs SOT and to get home at 20.00 (13-14hrs on battery) with still 20-25% left... With most stuff turned on. At least based on this forum and yt tests and what i heard from acquaintances that bought the phone..

I love this phone, its system, features, everything, but idk if im prepared to charge it 2 or more time a day for the next 2-3 years,as i did with s7edge...

Ps: in 16minutes to finish this post it dropped from 10% to 6% already on medium power saving mode...

Thank you for any help
