Hello
I have a A5 2016 (A510F) that has been under Android 7.0 for a while. A few days ago, it prompted me to do an update. I didn't check what it did, and installed it ; the version number is now "NRD90M.A510FXXU4CQL7".
After the update, the battery was dropping alarmingly fast, literaly 1% per minute while the screen was on.
I "re-calibrated" the battery by letting it drop to 10% and charging it back to 100%. Since then it's better, but I feel that it hasn't gotten up to its previous battery life. Before the update I remember using my phone normally for about 2 days without charging it, but yesterday it has dropped from 100 to 0% in one day for the first time ever, without my usage changing.
So my questions are :
- is it normal, has anyone else encountered the same problem ?
- can the battery life climb back up ?
- is the update responsible for the battery life drop, or am I imagining it ?
- if it is because of the update, is it possible to revert the firmware to a previous version ? I have found downloadables at "samsung-firmware.org", is it safe to grab them there ?
Thanks for your help !

my Note is UK but no update to 4.4 yet.
Last couple of days very large battery drop without a good reason.
Checking Battery it tells me that Android OS is using 45% of the battery.
This cannot be right can it?
Recently installed Clean Master but nothing else new.
Help please.
hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.

I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?
I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.
Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .
Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

Then it's the battery, most likely.
Hey guys,
My A510FD has been suffering battery issues for a long time but it's getting worst nowadays.
100% charge used to give around 9 hours of screen on time but after some time the battery starts dropping from 20% to 0% in matter of seconds.
Nowadays, it drops to 0% from 30% and when charging it only takes few minutes to go from 80-100%.
I think it's because the battery capacity is getting lesser. Anyone else has this issue with their A510? I've replace a battery at Samsung center around 10 months ago and same problem happened to both batteries.
Thanks.
Same issue

Same issue here guys... please help.
What ROM are you using ?
Because some custom rom are eating battery.
The best battery is often on first version (Lollipop downgrade)

Ok, maybe you should downgrade to 6.0 or 5.0 (5.0 is the best), i'm having some battery draining on 7.0 TW
Also you should try to use some hibernation apps like Greenify
Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
After Android Pie update on Nokia 6, overall battery life has been reduced drastically. Even keeping the phone edle has caused battery to drain about 20%. Even with adaptive battery ON, there massive battery drainage when compared to oreo in a given time.
Anyone with same issues and any suggestions for fixes or workaround?
I'm facing with quite similar issue as like you, but I haven't able to update my phone, because the battery level stays at 20% even if the phone is on the charger at all day (TA-1021). This problem started 2 days ago. Everithing is official on the device, no mods have made. It's just a year old phone.
