Recent update also adds "soft change" which charging a bit slower, lower voltage and about 10% less (after restarted the phone it "adds" 10% re-calibrate\stretching ) after that the battery recognized as 2450 instead of 2700ma
it should save battery total life in expanse for shorter run time per charge
anyone using it?
( i usually using phone for 3-5 years b4 buying new one, so it's important to me of its working especially when the battery is not removable)

sorry for my pretty bad english
When i first heard about this, i didn't think much of it
Tried it last night and after a whole days usage, it still had 58% (Usually I would be on <10%)
I think it does help, just takes longer to charge

I think that was just a weird coincidence. It is my understanding this is meant to prolong the lifetime of the battery (from 1-2 years to 4-5 years).
And this means that with this "battery optimization" option enabled, when it reaches 0% with ("battery optimization" enabled) it actually still has 30% left, or some thing like that. It just lies to you that it's at 0% and shuts the phone down. And maybe also not put as much charge in the battery ie. instead of charging to the previous 100% it charges to only (what would have been)80% (but it still shows as 100%, because of a software change).
This results in putting less strain on the battery (by never actually fully charging or discharging), hence giving it a longer "lifetime" from the usual 2 years to 4 or 5 years. There is a study here about this.
In your case you were probably lucky that no app started misbehaving, or you used it less than usual. My battery level at the end of the day varies widely from day to day.
Where can I find this option? I can't find it in settings.

Never mind I found it. In About -> Status
If you don't need battery life much, just leave it on. They put it there for a reason.
But if you're the type that upgrades phones every year and you just want more battery life (day-to-day usage). Turn it off.
I turned it off.
is it affecting battery life or last longer? i mean the energy not the health of real batteries on phone
sorry i'm not good at english

My SGP5 battery has been wacky since day one. First few days I didn't think it would charge past 80%, but I found if you charged it overnight it would hit 100% (that's after an 8 hour charge to 80%).
Today it showed 100% all day. I booted it and now shows 30%. The settings battery status does not show actual time on the lower scale. Like I said I was at 100% all day, and the chart goes up to a 100% peak, but doesn't flatten or go down.... as if the battery clock stopped (not there is such a thing).
Can't do a battery pull... could rooting solve this issue? At least you can do a calibration with root. I just don't want to root if this will be fixed in an update. But I really don't like not really knowing how much battery is left.
I have a similar issue. It seems random- I use it all the time and literally 1/2 of the overnight charges I put it through it gets to either 80% or 100%. What I've noticed is that even when it says 80%, it still performed as if it was fully charged.
I rooted my device a few days after I got it and I honestly didn't notice the issue until after I rooted my device. So it may be different for you.
I'm not rooted. Have you tried something like: http://www.appbrain.com/app/battery-calibration/com.nema.batterycalibration or manual calibration deleting the battery stat file? I'll gladly root if it solves this problem.

Same here, mine has all the same problems and also the Horizontal calibration never settles
Sent from my SAMSUNG-SGH-I727 using xda premium
To show how squirrely battery charging is, I monitored with Battery Monitor Widget and looks like this, one charge overnight without unplugging:
(each grid line is 1 hour, little over 1 day shown, screen was NOT on during charging)

Ok, here is my problem.
The battery indicator its stuck either at 100 % or 95%. I know my real batery life with a program (battery indicator pro).
It seems that the only way to charge it correctly is power it down and plug it to the charger (original by the way). If i charge it while is turned on, the indicator that signal the 100% charge never pops up.
I'm using the go launcher ex, its not rooted, and the stock rom (2.2.2 International).
PS:Yeah i know, my english is pretty bad, so please bear with me.
Mine gets stuck at 80%, both charging and discharging. After 3 or 4 hours at 80% it will go to 100% a few hours later. Hopefully they'll fix this on an update! The battery itself seems to be operating properly.
Well... I guess I take comfort in knowing that I am not the only one experiencing this odd bug. I have the exact behavior and like it's been said, my 5.0 player seems to have normal battery life. I just can't trust the charge indicator.
The method this device uses to estimate state of charge is VERY primitive.
It has a fixed table based purely on battery voltage - the problem is that battery voltage can vary quite a lot for a given state of charge depending on load.

I'm not sure why they didn't use the MAX17040 fuel gauge that is built into the MAX8998 PMIC...
mV readings seem more accurate than %:

mV readings are a poor estimate of state of charge, since they'll go up when on a charger, and down when under heavy load.
Our battery % indicator is derived directly from those mV readings. (Which is why our battery % estimate sucks.)
What IS odd is that you seem to have a case where the charger held flat at around 4060 mV for a while - which does correspond to an 80% reading. I think I've seen that once too, might be a kernel bug there, I need to look.
Showing 100% with the voltage dropping shouldn't have happened - I've never seen it myself.
I believe the "stuck" numbers are 80%, 100% and sometimes 65%. Happens every cycle for me, 80% being worst. But on a reboot, immediately drops 25-35% (depending how long it was stuck for). So if you reboot every hour, it will show good readings (but I reboot about once a month).
My tablets battery will say 100 then how down to 3% so ill turn it off then back on and it'll say like 35%. Then most recently its been stuck on 35-37% for some odd reason.
Did you guys try wiping the battery stats in CWM?
I dunno, maybe its not quite problem, just curious. When I had Palm, there when I unplug my phone, it immediately turn 99, which is normal I guess, because from mathematic view, hope you will understand.
But on my SGS2 I have 100 for some time. I am using Battery widget for monitoring battery, so I see, when I charge there was 4188 mV (calibration used here), I unploged, now it is 4150mV, and still 100%. Weird.
So is there something with it?? Do you have the same with it guys??
Thanks for replies.....

Nothing is wrong. Android uses deep sleep feature which allows it to drain very little energy while locked and throttling while idle, so you'll stay at 100% for a while. That's perfectly normal.
Also if battery loses some of it's physical capacity over time due to charging cycles - the new, lower capacity value will still be reported as 100% when fully charged, it'll just go down faster.
wow is this thread ridiculous.
back in the day, people were satisfied with 3 or 4 battery bars, just to be generally informed whether they would have to charge the device next week or the week after and these days people are obsessed with their battery life (partly due to it being generally poor). i can understand the many people who are falsely claiming the android os bug, most of which are just unable to understand percentages, other people want to show off their battery life by running the phone in airplane mode and never installing any apps, just to show off "who has the longest", while robbing their phone entirely of its purpose...
and here we are, debating about fractions of % of the battery level which mean absolutely nothing.
i guess it makes sense, that 100% stays for longer than a second, because until 99.5 percent, it would round up. or maybe it counts from 100.0 to 99.1 and only when the .0 digit is triggered, the number goes down by one, effectively most of the time showing you 1% more than you have, but honestly, WHO CARES?
The problem:
Lately, well it's been quite a while actually... my battery stats seems to jump whether i'm charging or discharging.
While charging sometimes it jumps from 30% > 80% > 100% within 15 minutes (this is what happened today) while discharging, it jumps from 90 > 50 (this quite often) then to 20% > 5% then off. My max usage time without charging is usually less than 1 hour.
I've tried to do battery reset (charging while the phone is off until full, reset battery data, then use it till it 100% drained)
I've tried to charge from 30% to about 80/90% then use it as usual.
I used original charger from motorola, used blackberry charger, samsung charger, no difference.
Unfortunately no good. Currently the ad hoc solution is to use battery powerbank constantly while I'm not near electrical plug. But its bulky and well not the best solution.
My question is, does the problem lies in the battery or at the battery controller. Is there anyway to test where the culprit is?
Thanks in advance
Battery daemon Moto uses is imperfect in calculating the battery percentage.
However, the jumps you experience and the backup you're getting, looks like your battery has worn out.

Hi, thanks for the input. My question then, will replacing the battery help to solves the problem? Cos lately the battery stats seldom runs over an hour. Here's a screenshot of my latest battery stats...

Your battery is definitely worn out. Replace it.
A new battery will certainly remove the issues..
Use the 10% mod though else you might still have infrequent jumps..
I just got the Realme GT 2 Pro after replacing my 3 year old Xiaomi one. I want to use this new phone for at least 5 years, and I've been learning ways to help the battery not die quickly. I've learned to charge the phone until 80% and I've been doing that for a week and a few days now. It does annoy me that the battery feels weak since I am missing 20% charge. I'm contemplating to just charge it normally, but on a 10W charger rather than the 65W charger it has. Should I continue charging it up to 80% or just use it normally?
20-80% is best but decay is inevitable
You could probably get AccA and set a charging cap.
https://github.com/MatteCarra/AccA
If you look at charging chart, the OS keeps battery at around 75% overnight

Down the road, replacing battery does not seem hard.
AccA Need root?
I cannot see the point of this, and with all respect I doubt this phone would be worth using after 5 years. More likely will not get any security updates by then and I dont think it will have much custom support either. On the other hand the manufacturers just sh1thing out 100s of phones a year, god knows what phones we would have in 5 years time, but for example I wouldn't want to use an old Sami S8 or 9 as my daily phone.
It is a good device and I like its battery life. I use it as a secondary phone therefore I share the battery usage with my other phone. In my usage I get a day and a half or 2 days out and would still have around 30-35% left. That's when I normally charge my phones, never let it discharge totally. I have seen in some articles that some experts don't recommend charging it over 80% due to the quicker wear of the battery. Honestly I cannot back this up.
There are a few things however what I can.
Do not charge when the phone is in use, like you have a long gaming session and you charge at the same time. The heat is the biggest enemy of the battery and charging and intensively using the phone at the same time could cause quicker wear out.
The second thing I never do is plug it up to charge overnight. With the quick charge tech this device has, its not even needed because its charges up in around 30mins for me. As soon as charged I disconnect. I noticed on my older iPhone when I charged it overnight, it caused quicker wear.
The above is my experience had over the years using several smartphones, but I hope it helps. Or just good luck using your GT2 pro in 5 years time
