I once callibrated the battery without any need (maybe incorrectly) hoping it would improve the accuracy further but ended up in a problem!
Now my battery skips from 60% to 49%, 14% to 4% etc.
I tried callibrating the battery again many times (this time, correctly), but no luck.
It always skips those levels!
Anything I can do about it?

i have noticed that the battery metter is completely unreliable
for example it shows 28% left (btw, i installed FInixNOverBattery for percentage indication) and after a soft reset it shows 41%
or it shows 50% and after soft reset it shows 31%
in this way i can never estimate how long the battery will last
does anybody faced this issue? any solution fot it? (i also tryed to calibrate by completely drain the battery followed by complete charge withe the device turned off)
thank you in advance!
noris08,
it is completey normal to experience big jumps in % after a reboot. The battery % is just a representation of the actual voltage of the LiPoly battery, which usually recovers (rises) quite a bit when there is no load on the battery (even for a short time).
maybe what you say it is true, but i never experienced this behaviour with any of my previous phones. and i had a few, including wm for a few years
and variations of 10-15% - i find them too big
I noticed the same thing. Any explanation for this? Or it is just that FInixNOverBattery is not reliable/compatible/accurate ?
Voltage may vary/jump around due to environmental changes and power consumption or voltage sensor may be insufficiently accurate to provide reliable voltage readings for 1% steps. This is one of the reasons why many battery drivers in WM only provide remaining charge percentage in 10% steps.
In this light, voltage on its own is not a sufficient indicator of remaining charge percentage. Other parameters, such as voltage deviation and other factors, such as power consumption and temperature may need to be taken into account to obtain a more accurate evaluation.
Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...
Firstly, this is in relation to the battery drain issue concerning the 'time without signal' bug.
Okay, I've done three repeated tests, all leading to the same results. Basically, it seems that when I restart/reboot my phone, a number of applications etc. show up in the 'battery use' menu, including 'Android OS' and 'Android Operating System', 'Dialer', etc. Battery drain at this stage is quite bad at around 8-10 (Battery ETA) percent per hour with barely any use. Now, when I plug my phone briefly into the computer letting it charge a few percent, and then unplug it (under usb setting, without detecting sd cards), these applications reduce down to only four in the 'battery use' menu (Display, Cell standby, phone idle and android system).
More importantly, the 'time without signal' info mysteriously disappears from the 'cell standby menu', and battery drain reduces to 3.4 (Battery ETA) percent per hour with me playing around with the settings/apps etc.
This seems like a temporary fix to what seems to be a phone radio searching/standby issue. Can others try what I did and report back? I have little knowledge in application development, etc. so I'm hoping someone can deduce the source of the problem from this information.
Also, my phone is a stock galaxy s i9000 from virgin mobile Australia.
Update: same effect also with wall plug. Phone must be on, and only after cable is unplugged, the aformentioned occurs.
Hi.
I also notice the issue.
For example, after 4 hours and 18 m, I'm with 70% of battery left.
And I didn't do ANYTHING. Just navigate through the menu.
I tried many ROMS and the issue remains. Now I'm running on the Darky's ROM, and it is really good. Someone says that reduces battery consumption. I didn't noticed that.
Anyway, I always do the recharge with the device ON but I don't see battery save. ~10% consumption per hour.
I tried everything to reduce the battery drain!
Now I'm testing SuperPower from XDA (you can find it on the market), it's amazing, it allows you to configure profiles in each states of the phone: awake, lockscreen, sleep. It can slowdown CPU speed, disable WiFi and Mobile Data, disable autosync, and more.
Sounds good each of these features, but remember that it is still a beta.
I'm using it right now, but as you can se, the battery drain continues....
There is a sudden quick battery percentage drop and then it normalizes in the 20% Mark again. Need solution.
Same happened to me the problem was battery just getting old after I bought a new one it was never a problem again if it's not that then it might be a problem with a rom or battery calibration
You can do battery calibration. (require root)
You can do battery calibration. (require root)
Same happens to me, it remains 20% then suddenly drains abruptly !
First of all I have never posted any questions online before so excuse me if I'm missing some info that I should have posted please inform me of any missing info.
My note 3 SM-N9005 has this very weird problem.
The battery drains 1% every 2 minutes. with airplane mode but wifi on, screen brightness on the lowest level, not using any application.
(If I'm playing a game or watching videos it goes from 100% to 0% in about half an hour or less.)
This rate is after fresh install of custom rom. I've tried more than one rom, I've tried stock lollipop rom, more than one Cyanogenmod roms and lineage Oreo 8.1. They all had the same battery consumption.
Plus whenever I check the battery consuming applications in android settings, The sum of percentages consumed by everything isn't anywhere near the actual consumed, for example the sum of consumed battery by applications is 9% and the battery percentage is at 66%.
I've changed the battery three times so far and tried the battery on another phone and it seemed to work just fine in the other note 3.
I've tried changing the charger but still the same.
I just want to know what is causing this fast consumption even though I've changed everything.
I have the exact same problem
