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 am writing this thread today, in hope of getting some battery tips from you lot, why? Well because my phone is having some serious battery issues, it only lasts 6 hours max, no matter which rom is on it, which is just not good enough.
I have used the stock froyo rom, SlashDW's CM 7.0.1 unofficial rom, and now running Frosense, by Rushness, but i have had no sucess with this battery problem.
Hopefully someone can help me solve this issue, i would be very greatful, thanks.
Try to wipe battery settings from recovery before flashing rom.
like extrahacker said, wipe battery stats... than leave device powered off and charge till full, than re-install rom of choice
I looked at a post regarding that on the web, and followed the instructions. Charged till full, wiped battery stats, and then let it drain and charge again, still no luck. Any other ideas? Thanks for your help, you both
I find that the CM roms are very battery consuming. The Froyo for Trout rom gives me a full day.
You must also consider that the battery is 2+ years old, it would have high battery wear. Which might explain why you have bad battery life.
Agree with Ace42 - I recently acquired a G1 and the battery life was shocking, I was lucky if I got 4 hours! I have just switched on my phone with a new battery from ecell off ebay and will give it a blast over the weekend.
It can't do any worse but I am hoping for at least 8/9 hours!
OK so the first day I just scraped 24 hours... it must have been the old battery!
I can't complain!

I don't know if I'm the only one who's noticing this but I just came off 4.3 TouchWiz onto SlimKat 4.4.2 (Build 5) and I'm noticing battery drain like crazy on my mobile. I thought it was bad on my previous stock ROM after the horrendous 4.3 update Samsung provided but this is worse. I used to get around 9-10 hours of battery life which has been reduced to around 6-7 hours now (I know it's not a HUGE difference but I'm not a fan of charging my phone twice a day). Overnight (despite leaving it on flight mode) the battery of my phone drops by 8 odd % in around 6-7 hours. Does anyone know the cause of this and can someone please help me?
Thanks

1. Switch off Google now.
2. Root.
3. Install Greenify + Donation Pack.
4. Greenify the intended apps.
5. Switch off Location.
6. Turn off animations.
7. Turn down the brightness.
8. Turn on the dark slim mode.
9. Switch to 2g.
With the above, I get 1+ day of battery on my i9300.
Read in other forums of other ROMs with 4.4.2 that battery drains with this KitKat version
Using omni ROM 4.4.2 battery drains on this too. Could it be Version specific problem ?
For the past week my phone has had an average of 7 hours of use. It's not even heavy use! I used to be able to go 13 or 14 hours before it was close to dying, now it gets near to 7 hours before I have to plug in. I got a new battery and put it in, but I'm getting the same results. I know you can't really tell much from battery logs and screen shots, but I've attached those in case. I lost root with the last OTA, so I can't use the Wakelock Detector. I have no idea what's causing it besides "Android System". Any help would be greatly appreciated.

I understand your frustration and would like to help. First do you use your screen brightness. Do you keep sync on constantly or have a app like juice defender that will do it for you? Have you checked all of your apps to see if any act strange? I know this is a lot if ?s but I don't have your phone. We can do this. You said your not rooted did you Odin the stock firmware before taking the ota? You have a new battery is it samsungs? Or is it a different brand? Have you calibrated the battery or deleted the battery bin file? Have you factory reset at all in a long time? Do you do the battery saving tips like dim screen power save mode to get extra juice? When you get up your phone is 100% and in 7 hours of use needs recharging. Is that with moderate use or heavy use gaming or do you get a but load of twitter notifications ect. I saw on the photo twitter notifications constantly getting those can do a number I keep sync off. I don't know if there are any known bugs in 4.4.4. I had to root do to 4.4.2 for 4.3 because of poor battery life I was in the same boat.

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.
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 !
