Solved: New S20 FE 5G battery draining

Yassir90 · ‎01-07-2021

Hi,

I just bought a new S20 FE 5G, it's now my fourth day with it, all the updates already downloaded, I have noticed many things about the battery as it goes from 100% to 99% in 2 minutes, it went from 100% to 96% in 15 minutes, on the third day after all the updates and downloads and the phone on stable status, the battery delivered 5:30 hours screen on time and 15 hours overall.

I have heard a lot about how much the S20 FE 5G battery is good, so I feel there is something wrong with my device, so please, any advice?

Kind regards.

Right, so I have been using the phone for almost 5 months, so from my experience, I would say there is nothing wrong with the battery, so my explanation for why the battery is going down from 100% to 99% so quickly is Samsung is not fully charging the battery as a safety feature and to extend the battery life, well, Samsung should be clear about it and should mention it in the battery info or somewhere else.
On the other hand for the battery draining issue, it's no longer exist, so it seems the phone has learned from my usage pattern and has optimized the battery life, also Samsung should add a clear note about it as me as a new customer could freak out and feel bad about a new phone's battery draining.

Hey Yassir90!

I'd be more than happy to help out with some troubleshooting steps! Please could you allow your phone to drop to 50% from a full charge, and then share a screenshot of the Battery Usage screen? You can find this by heading to Settings > Device Care > Battery > Battery Usage.

It will give us an overview of what applications are using the most battery, and whether there's anything at fault there!

Hi ChelseaH,

I will do, but just to mention, I have restarted the phone before unplugging it out this morning and I have checked the running Apps, there were four apps running, WhatsApp, google play services, media storage and outlook, nothing really major, so when I have unplugged it went directly from 100% to 99% in 2 minutes then from 100% to 96% in 15 minutes. does not feel the right behave of a new phone with a new battery!

Make sure your screen brightness isn't too high, that impacts on battery life too.

ChelseaH, Now I'm running an on-screen test running Youtube I will post to you what you have asked when the batter reaches 50%

Mitzzz999, the screen brightness was below the med brightness, that's what makes my more worried

Is your Bluetooth and NFC always on? Sorry, I'm just trying to help you get to the bottom of it, you may already know the suggestions I am giving.

Hi Mitzzz999, for sure I highly appreciate your help, but yeah the Bluetooth, NFC and GPS all were off 😞

I made sure nothing insane using the battery!

I was really hoping to get a full day of usage.

I'm not sure what other things need to be looked at, hopefully it all gets sorted out for you in the end.

Hi ChelseaH,

Here is the screenshot for the battery usage, by the way, my brother has POCO F3 and he got it like me at the same time, his phone has the same battery capacity and same screen size, but his phone battery doing way better than mine in regards of the screen on time even he has his Bluetooth, GPS and NFC on while mine is off, for him moving from 100% to 99% it took more than 30 mins while min took literally 2 mins, I just find it no sense, I'm really disappointed.
