General Battery Life

Search This thread
That sounds miserable. It's a shame the 5G there is so terrible or you definitely wouldn't give it up so easily. It's also a shame you have to run your phone like it is four years old when half the specs are already those of a phone two years old.

The entire purpose of things like the adaptive refresh rate is so you don't have to lock it so low and can still take advantage of the lows for light use. Managing background apps and tasks can make a huge difference in network usage, but also reduces the load on the processor that will allow it to run at lower speeds when it's not doing much work.

Sure, running things at their lowest will still get you better battery life. The cost, though, is having paid $1000 for a folding phone that works like a preproduction test of the Z Flip (1). At that point, the folding is a novelty that cost much more than it's worth.

The real shame is that Samsung locked down the phone and prevented people like the ones here from really making any real improvement. You get stuck thinking you need a 4G on 60Hz when it could easily be a 5G at 96Hz with the same results.

I hear you and I fully agree.

I'm on t-mobile. Hopefully they get their 5G up to speed where I live (pun intended).

Between the battery consumption during usage and battery drain in standby, I found myself needing to charge the phone after 10 to 12 hours (before the changes I made).

Hopefully a system update (or perhaps root and custom ROMs) will allow me to run the phone as intended without it dying on me midday.

At least I got $1,000 trade-in on my prior phone whose specs were sub par to this phone - yet I'm running thIs phone below its full capability because of the battery life. SMH

I guess if you got the phone for -$1 / $50 by trading in something 2+ years old it makes sense. Not entirely sure where you found a deal offering $300 more than the max offer from Samsung and $200 more than T-Mobile's bill credit max, but congrats on finding that once in a lifetime deal.

T-mobile still has that deal going on. The details are on their website. I had a phone that qualified for $1,000 trade-in value. Of course the trade-in value is done via 24 bill credits that equally offset the 24 monthly payments for the phone. If you cancel at any time before 24 months, you lose any remaining bill credits that you hadn't received and you have to pay off the remaining phone balance. So they lock you in for 24 months with that carrot on the stick.

I'm gonna re-visit the refresh rate issue and try out an adaptive refresh at 96hz max and see how much of a hit the battery life takes. I can't do anything about the slow 5G speed in my area so I'll just continue to use LTE until t-mobile builds out a faster 5G network where I am.

Oh ok. That wouldn't have been for me. Family plan would have credited someone else.

Kind of poor battery life but considering it's my first charge I hope it gets better in time.
Screen on 120hz, medium usage on Wifi most of the time.

At&t won't let you disable 5G. You have to use the dialer code *#*#4636#*#* and choose a profile that doesn't have NR, that's 5G radio. The icon will still say 5Ge but apparently that's LTE.

Battery is great once it settles down. Max standby is 2.5day, max SOT is 6hours. My typical use of 2.5hr SOT gave 1 day in the beginning:

, and after 2 weeks and limiting battery to 85%, it now gives 1.5 day:

Root, 96Hz, permanent BT watches, pushbullet, kdeconnect, VPN, AOD, wakelocks and effects on. Lil car charger bump there, but to me it's on par with previous Note20Ultra. Except now i can fold™ and the screen is finally scratch-free.

I won't complain about battery life on this phone. It is small, yes, but the main feature isn't the cam, nor the CPU and neither the battery.

It takes me to the end of the day while being foldable and fitting perfectly in the pocket.

BTW, fully charged at 7.00 am now it's at 15% and I have been using it all day long.

If I was looking for a battery phone or a camera phone I wouldn't pick this for sure but since I was looking for a phone with a big screen that fits in my pocket, I've made a great choice.

You could try installing BatterBatteryStats (there is a thread on it on XDA, with plenty of tips to understand what's going on)

From the little information you shared, I would try force-closing Twitter :)

Before A12 I was doing fine. I woke up 1.5hr ago, have done virtually nothing. And this. **Now 80%**

Revisit any settings and apps previously disabled. Major version updates tend to reset a lot of it.
I've never disabled anything but 5G before. It was bad for the first few weeks getting the device, but then I got Galaxy Max Hz and it fixed a lot. Updated to 12 have Max Hz and now down to 77%. It's literally like the battery is leaking.

Heavy drain should be expected with everything running.

As stated before. I wasn't draining 25% in under 2 hours before. I was getting easily a full day with Max Hz as the only thing helping my battery. 25% in under two hours when I'm literally checking maybe Facebook, email for a few moments at a time is unheard of. Literally pulled it off the charger and watched it drop 1% seconds after. It wasn't like this on A11.

If you have a suggestion list of what to tinker with I'd appreciate it cause before A12 I could get 3-4 hours into my work day before hitting 74%

I saw what you posted, but it doesn't matter. I think you're overlooking the fact that it isn't Android 11.

There is no one perfect list for everyone. Go through Settings, especially "Advanced features" and "Battery and device care" and see what of it you don't actually need. Go through your app list and see what you don't use. Uninstall, disable, or "adb uninstall" (see any one of the guides) those apps.

Alright I'll see what I can do. I'd assume dowmgrading is out of the picture haha.

    @EVOme, the battery will get better when it will finish learning your usage patterns. As for the camera, I agree with you, but you bought this for other reasons. It's a flip phone with a big display that folds in half. 😃 They cut corners to bring the price down. Maybe in 2 years we will have a folding phone with great cameras and a lower price, who knows?

    the only thing that did it for me was turning off 120hz refresh rate. sticking with 60hz visually hurts but it improves battery life a lot. it is now capable of getting me through the whole day easily and lasting around 24hrs. SOT is around 3 hours.

    This thread is scarring me. My phone will be here on Weds. I am currently using a 12 Pro Max. I have a feeling I will be hating life with the Flip.
    Battery is not pro max level, but it's ok. After one week I get 24h with 4-5h sot. I'm ok with that, considering what this phone is. I sold my S21Ultra that had almost double the battery life and much better cameras, but I'm still happy with the flip. This phone is amazing.
