Galaxy S10 has a frustrating bug that’s killing battery life

No smartphone launch would be complete without some initial teething issues, and in the case of the Galaxy S10 that’s a rather frustrating bug that results in Tap to Wake activating when it’s not supposed to, like when the handset is in a bag or a pocket — but it seems to be isolated to the US.

“I have an S10, and I keep my phone in my pocket with the screen towards my leg (since my leg is far less likely to damage the screen),” writes one Galaxy S10 owner on Reddit. “The only issue with this is that I started feeling the “fingerprint rejected” vibrations while the phone was in my pocket.”

“First thing I did was activate tap to wake, I have never seen this in a Samsung phone before. Now I have the newest that Samsung has to offer and it does not work properly,” explains another on Samsung’s US Community Forum. “My leg through my fabric taps the phone and opens it up.”

The issue results in consistent battery drain as the screen is waking up more than it should be. In some instances, Tape to Wake is also triggering the camera, which uses up even more juice as a host of sensors are subsequently activated as the handset thinks it’s operating in low-light conditions.

Samsung’s advice? Disable Tap to Wake and the Always-On Display. But that’s far from good enough — when you’re shelling out around $1000 for a product, it should work as intended. You shouldn’t have to disable a feature, or two, to help it last an entire day on a single charge.

The issue doesn’t appear to be affecting everyone. Almost all the reports we uncovered were from customers in the US with either a Galaxy S10 or Galaxy S10+, indicating that the bug is an issue with the region’s firmware. If that’s the case, Samsung should be able to fix it by a software update.

The actual reason for this problem is neither the double tap to wake-up nor the finger print scanner or anything else. This was bugging me for last 1 week.

After fixing this now it is all working fine for last 1 day. Basically Samsung introduced a new feature called “lift to wake-up”. This is the real battery drain i can tell. Double tap to wake-up was there in all LG phones or one plus phones.

I disabled the lift to wake up and now it is all working fine.

LG has had the similar Knock On feature since G2 or so. Never had an issue using over 3 iterations of the phone. Came back to Samsung with the Note 9 last year & was surprised a similar feature wasn’t present. Now they bring it on the S10 & it’s flopping…
You lots are neighbours, right? Knock On LG’s doors for some tips, Samsung.

It does not wake in my pocket, however, I have noticed when on a call my ear is constantly pressing things on the screen. This device does lack a proper proximity sensor, right?

This never happened on the proximity sensor-wielding, bezelled(not sure if a real word lol) devices of the past.

I find the battery life is pretty much the same as the S9+ standby time is terrible and for the to be have 4100 mha battery I’m very disappointed with it.

Not only in the US. My S10 bought in France has the same problem. Every time I have the phone in my pocket with the screen towards my leg I can feel vibrations due to the fingerprint sensor.

Maybe it’s the finger print sensor as some states or even both (tap to wake and the FP scanner)? But even then, why it works when the proximity sensor detects something super close to it? It should turn off all kind of screen on/fingerprint scans. :/

Hi,

I have not experienced problems if battery is drained at S10 + (Exynos).

I have experienced the touch sensive on the mobile screen is very sensitive on the edges of the S10 +.

S10 + unlucky to open apps or bump into the choices on the edges.

Sorry, but I’m not good at English.

I know, my English is crap.

It’s called Samsung – battery drain is their speciality.

Tried with the “prevent accidental touch” option?

Cover the top part of the screen with a piece of cloth, or even the palm of your hand, double tap the screen and it will still turn on. I have an exynos S10 Plus and happens with me.
I believe that this is a software bug that will be updated soon.

I don’t think it’s a bug. I’ve been having this problem since day one on UK S10+ but was never really bothered to go out and start writing articles about it. To me it neither tap to wake or AOD. It’s the fingerprint scanner designed to work even with the screen off. And I’ve heard that in display fingerprint scanners can mistake pocket lining for a fingerprint read. At least that’s what I think is happening on mine. I get “No match” vibration while the phone is in the pocket all the time. But like I’ve said, I don’t think… Read more »

Note 9 exynos. Tap to wake works just fine but lift to wake feature caused the same issue when phone was in a pocket.

No issues with Tap to wake up feature so far, but i had one with Lift to wake up. Whenever I insert the S10+ in my pocket, display turns on automatically as it assumes that i am lifting the phone. After I found some abnormal heat in my pocket, I realized this issue and turned off this feature. So far no problem for me

I don’t have problem with the tap to wake, but the always on display is always on even in extreme dark, which is annoying

Yep, even when the phone is turned over.

Advanced settings. And movements off. This was the issue for me. Note8 though.

S10 uk user and never had that issue. I have the aod now as I don’t have and led light. But set to tap to wake. First thing I did was turned off almost all the gesture except for double tap to wake and swipe to make calls as a standard setup. Most of the other features are useless.

The AOD does not go completely black like my S8 did. It dims, but never more than that.
