Losing large battery % overnight (standby)

[anon(10311036)]

Only had my S9+ since Saturday and I know battery often takes time to settle but I'm not impressed so far

My main issue though is overnight, I leave my phone on but in flight mode and aod off and last night it dropped 11%. Going to test again tonight but this seems excessive and no clues in battery stats (either stock or gsam)

Anybody else experiencing this?

Man mine has dropped 25%! Its driving me crazy! Not using AOD and I haven't found anything wrong with any app!

Erm... My S9+ drops around 5%-8% when i sleep. 11% is a bit too much in airplane mode though. Did you close apps?

Owh dang thats bad. Btw what version of the S9 do you use?

I've grown to accept that the standby on my S9+ is awful and I'll just have to deal with it. I sometimes go through periods where the battery loses 2% an hour on standby. Usually, even with Location service disabled, I get 4-6% drain after 8hrs on standby. That may not seem bad but my previous phone - a Lumia 950 - only lost 1-2% after 8 hours and that's with Location enabled.

What really irks me is that I will switch to Airplane mode for long rides in the subway and still lose 1% every hour.

erm you might have to bring it to Samsung for repairs or replacement...the only phone which gave me crazy overnight drains was the LG G4.Other than that everything is good.

2% per hour is very good.you cant expect a phone which is ON to not use any battery be it airplane or not airplane mode.

okay lets do math,2% per hour.so 100% gives you around 50 hours of standby time.i get around 36 hours of standby time on average and i dont see a problem.

and correct me if im wrong but isnt Lumia 950 a Windows phone?

From my expierence, uninstall any battery saving or monitoring apps. They can interfere with Doze. My S9 in standby takes about 1-2 % every hour when connected to wifi which is perfectly normal in my book. It's slightly higher on LTE but my coverage is kinda wonky at times and I often don't have a full signal.

I've been leaving my S9+ sitting here with light usage every day to see how long I can go on stanby. I have the US unlocked version on T-Mobile. I should get about 6 days standby.

I had the same results last year with a US unlocked S8+.

I expect a current gen flagship to use less battery than my previous phone. Especially with the newer chipset and larger battery. I don't think that is an unreasonable expectation.

It is.

erm no android ATM can do what your Lumia 950 do...even my iPhone X cant do that...

Hey man, as I said, I did a new factory reset. I just lost 3% this time overnight. Still trying to figure out what was draining my battery, since I don't have almost anything installed and disable every bloatware I could. I also removed my SDcard, I read somewhere on XDA Delvelopers that a malfunctioning card can give this issues. Especially if you install the apps or use it for big files storage. This is what I got now, is it normal right?

What do you mean by light usage? I mean, what apps do you use and how often to get those results?

I had really good batterylife yesterday took the phone off the charger 6 am with moderate to heavy use by 4pm it was 30 percent a few calls and YouTube videos later by 5:10 I was down 10 percent I great to me

But with heavy use calls games movies 5 hours tops

That is disappointing to hear, but like I said earlier I will just have to live with it.

You know, with airplane mode off. My S9+ drains more than 5% overnight. But i blame it on weak signal.

With 3 hours and 49 minutes of SOT and 19% of juice left is not bad. Maybe because of weak signal?
