Thanks.. I tested out playing a game. The CPU % and GPU % .. No different. I even installed "CPU Throttling Test" to check CPU Max Mhz... No different as well. I would say "Power Saving Mode" on s21 Ultra is cacat. Not working.

What to do. Samsung phone is like that. It powerful and dont know what background processes keep running until it drains fast. I upgraded from n20u to s21u .. thoughts will have big improvement of battery but not the case... Maybe SOT from 3.5 hours improved to 4 hours only.

OK lah ... used device is it?.... if got 2 yrs warranty .. lagi ok.

Yes... It should be normal. I achieved 4 hours SOT .... around 25% used for gaming. Mine FHD 120Hz.

Dont you think Samsung Case with S-Pen Bulky? and also want to take off the case very difficult so tight. I got Samsung case silicone cover (without S-Pen). Thought want to use it, but it is bulky and heavy to me. So end up no use it. Also big problem is difficult to take it off.

Now using Spigen Thin Fit really thin and no weight add to my phone.

Is this UV Tempered Glass? Or normal Screen Protector?

Ok. Sorry I think this one only for s21+ with flat screen. s21u not applicable.

your note 20 ultra got "focus enhancer" after upgraded to oneui 3.1?

bro... playing game... i play 120hz game ... it heating like hell. And some reddit/xda from cold country. 40deg celcius to us is ok, to them is hot like hell.

When playing game ... with 25% usage on game, my SOT only 3 hours dropped to 20% battery level.

Hi I am thinking to buy Note series pen and use on my phone. Which note series pen no need to charge and I can use on s21u?

I just grabbed the POCO F3 last yesterday. So many years I stick to Samsung. So I need to explore other phone and check if Samsung worth to its expensive price.

Yes, happy to see samsung keep updating the software make sure up-to-date.

Thanks for all your replies and advise. Looks like Samsung still strong. But the sd870 on POCO F3 is so attractive. But I only managed to get 6GB.

Panafone, your F2 Pro 6GB or 8GB? Is 6GB good enough on Poco? I play some game like Tennis Clash / Alphaut.


Also never forget, Samsung provides many good feature, S-PEN, Dex, Windows Link... I believe only Huawei can compete with it.

Buy from Samsung Experience Store / Senheng / Courts. And they will give you free gift Wireless Charger Trio. inside there got charger you can use.

This phone is most expensive in Android. So normally I prefer walk in better.

Sorry. I thought you want local set. But s21, exynos and snapdragon no different.

Good price offer?


What is the price Tesco offer earlier on 27th March?

It is really sad when buy the premium expensive phone and need to turn off this and that just because of battery drain.

Well I suggest just use it as usual and charge it as necessary.

Yes. sold off already.

Exynos on s21 totally not bad compared to snapdragon. Of course still I will opt for Snapdragon if got choice. Considering local warranty, i think people dont mind exynos2100.

Compared with my note20u, the s21u is big jump in term of CPU performance especially playing game.

What is the different if you didnt turn on power saving mode?
