Hi all,
I have an S20 exynos and sometimes it heat battery quicker than usual and I cannot understand what is the issue. The battery stats are stupid in Android, if you sum all the % the total is not 100%..that's really annoy me.
Also i don't think is a particular app, but mainly something related to core functionalities or system things.
Every app is set for batter optimization, I don't have strange apps using battery, I don't have Facebook app installed, so annoying.
The issue is with background usage, sometimes I can do 6 hours SOT, sometimes I cannot reach 3 and half. My usage is almost the same every day, and battery stats show nothing abnormal.
Any idea?
(sorry for my English)
I would use Accubattery to track exactly which app is using your battery instead of the built in battery function which does not have enough detail.
Its exynos and the software driven idle drain.
A lot of people have pointed to the Exynos modem as a battery hog, even when the phone is idle.

I've done a load of tweaks to maximise the battery life of my Play, and am now getting a couple of days of light use on one charge. Looking at the percentages for battery use, I have "cell standby" and "phone idle" taking up 70% between them. Display is down at 5% even though that's the main culprit for everyone else's battery drain (judging from what I've read).
This made me think - Are cell standby and phone idle taking up too much juice on my phone, or are they just that high because the numbers have to add up to 100 however efficient you make it? On an optimal phone, should cell standby and phone idle be the biggest drains on the battery, or should display always be the biggest problem?
Yes, those should be the largest two values on a very optimized phone. The higher the "phone idle" % is, the better (because phone idle uses very few resources, a really high % means the other apps are using almost no resources). And yes, they all always add up to 100% (it may be a little off because of rounding). Also, "display" means the phone is on and in use, while "phone idle" means the phone is on but the screen is off (so depending on usage, either one of these could be higher)
I've had my Note 3 for a month now, and I noticed that after 90% the battery starts to drain a bit faster.
For example, between 100 and 90%, it takes about 6-8 minutes to drain 1% while doing something simple like using Facebook, reading an article, instant messaging, texting, etc. This is on Wi-Fi.
But as the battery goes lower and lower, it drains faster.. by the time it's in the 30s or 40s, it takes only 3-5 minutes to drain 1% while doing the same general activities. This is also on Wi-Fi. Even idle drain is faster.
By the time it gets to 20%, it's a bit faster... didn't keep track though.
Most of the times I have charged it were like this: full charge -> full drain -> full charge -> full drain.. etc
I have also tried the popular Battery Calibration app. It didn't seem to have any effect.
It is rooted, and I have frozen some bloatware (mostly some Samsung & T-Mobile apps).
I have not tried a factory reset yet.
Is this happening to anyone else? Maybe my battery is defective?
I wouldn't full drain your battery often. Try to keep it above ~20% if you can. Draining it low like that wears out the battery much quicker. Trying not to charge it to 100% helps also but that is harder to do and need a kernel that can support setting max charge.
But yes I noticed that battery does seem to drain a little bit faster after about 90%. Not a big difference though. And you shouldn't sweat it. Battery chips and batteries tend to have different characteristics from phone to phone and battery to battery to battery. Even though it should be an exact science, exact science battery chips cost a lot more. My note2 took forever to get off 100% but once it hit 99% battery drain was very consistent. Less so in note 3 but more or less consistent. Don't sweat it. I would worry more about trying not to drain your battery so low if you can. Your battery will perform best and last much longer if you can keep it between 20-80% but that is OCD. Just let it do its thing. Early android phones were terrible mostly at being accurate and consistent.

Hi!
As many, i had the problem of battery drain (it would go from 40/45% to 0% in a matter of minutes).
I orderer a new battery (not the Kompson one, the original Jiayu battery, at least it was sold as original and it even has the same serial number my previous battery had), but the problem continued!
Anyway, after much testing, here is the "solution" i have found:
As soon as you see the battery drain starting (it´s very easy to notice as you already know), go to battery settings and look at the percentage that each process spends of battery. Usually, before battery drain starts, everything looks normal, low consumption throughout all apps. But when the battery drainage kicks in, the last app you opened has an unusually high battery percentage consumption. For example, i have seen my ColorNote app at 45% consumption, Whatsapp at 50%, Reddit at 48%, etc...
These are all "normal" apps, not some shady app power hungry. What i do is, after i identify the app with unusual high power consumption (again, it´s usually the last app opened after battery drain starts) i long press on it (from the battery menu) and the i choose "Force Stop" on the app.
This immediatley stops the battery drain and the battery behaves normally and goes out at a normal rate until 1 or 2% battery!
I have tested this many times and it never failed me. Please try it to.
I think there is a little chance to catch the very moment when the battery drop start. Today I've got battery drain very quickly between 50%-40%.
I also tried some these "fixes". But the only solution is to change batteries.
people and me personally, have also found out that the enabled auto brightness control , often consumes a lot of battery after about Android 6.0
have a look also on that.
I've just tested a new Konpson battery and the battery drop changed. With originally Jiayu battery I have drop with 25%, now after 10% I guess and phone can hold some times (30 min approximately) at 1%. It's a little bit progress ;()
Yes, I know these battery drain threads are getting annoying, but I can't seem to find a solution to mine...
What happens is that after charging to 100% or near it, I have a very small battery drain (like 11-14 %/h), and then if I do something a bit more demanding (games, substratum, etc) my battery drain starts to get a little worse (16-20%/h). Even if I return to my light usage after my heavier usage, the battery drain is still there...
Battery usage is calculated based on capacity used over time since last charge. It's an average, not a real time monitor.

Click to expand...
Click to collapse
I know that... Which is why I have reset the battery stats, before returning to my light usage. The thing is, the light usage drains much more battery after the heavy usage the before.
Since the update to FVC7 my battery drains much faster than usual. During the 6-7 night hours it loose abt 10% and after around 8-9 hours of moderate use the battery rich around 20-25%. Better battery stats does not show any thing unusual.
any help will be appreciated.
I only noticed that Screen On time drains battery like crazy just having Display set to 1080p (Medium) and refresh rate on 60Hz (low).
For me it's "only" the display that drains battery very hard. Screen off time is pretty good, but I have a lot of Apps in Standby and Deep Standby.
But BBS was never adapted to Android 12 and Samsungs on Battery service is missing a lot. Look into RAM optimization which Apps are popping up that shouldn't do. Even if it's very low on RAM, if it's an App that hadn't been used since last boot and doesn't need to work in background, than it should go directly to Standby or Deep Standby.
I might be off, but as I'm looking at it: With (Deep) Standby option, Android 12 finally adopted Greenify a long missing feature on every Anroid OS.
