[Q] Battery Charging time more than 4.5 hrs

I have installed Infused ROM, still the charging time is same as before. Is there a way to decrease my charging time?
TIA

NO
NO there is no way to do this

So I have to handle with this 4.5 hrs of charging time

4.5? damn you must run your battery down to 5%.

Entropy's kernel uses alternative charging logic that supposedly charges faster at low battery. I don't know how effective it is, but you could give it a shot.

Are you USB charging or something? No way should it take you that long.

Yes, I am charging from 5%, Even if I charge from 50 to 100 it will take more than 2 hours.
the phone is charging 22 to 25% per hour. I dont think a phone should to such a long time.

can you tell me how can I update the kernel. I am new to android, so I am not sure with my Infused RAM, can I do this or not.

I didn't understand anything in this..

Try deleting the battery stats when you are at 100%... you can do this manually or with apps like " battery calibration" free on market, or go to system and delete batterystats.bin manually, try everything i guess.
I was having same trouble when i used to change between ROMS a lot now i decided to stick with Infused 1.6 Froyo did the "recalibration" with battery calibration app, and takes a few days for the battery stats to rebuild correctly again.
But now it hardly takes my Infuse 3 hours to FULLY charge.
And you can recharge at any point even if its on 80% or 95% if you have a power aroudn charge while not using... this batteries dont get "used" for recharging them before "time" they dont do memory you can recharge at any time.. there was a whole thread about that somewhere here on XDA sorry i cant post the link just maybe try the simple way.... recalibrate on battery calibraiton and give it a couple days to generate an accurate stats.
Also recharge while not using (working....eating...sleeping...)
If nothing works maybe... get a new battery? may be faulty i guess.
Hope it helps

Clearing battery stats does NOTHING on the Infuse, or any of the first-gen GalaxyS devices, or any other Samsung phone with the MAX8998 PMIC for that matter.

it's funny (sad?) that you need to say this over and over again every single day. you'd think people would come across another one of your posts, which are everywhere, where you said this exact same thing.

Then you need to figure out the common denominator because either your cable, charger, or you aren't doing something right.
That amount of time to charge isn't normal.
Have you also tried pulling the battery for a few minutes then charging it yourself full? Don't power down, just pull the battery.

maybe try draining the battery all the way to 0. Recharging over night interrupted. And doing it once more. Not sure it will help, but I'd try anything.

Install CurrentWidget.
In the settings, near the bottom, there are settings for "operator on value" - Set it to divide by 1.83.
Then plug in your device when it's discharged below 80%.
Currentwidget should report 600 mA if you applied the correction factor above. If it reports 1100, you forgot the "operator on value" settings.
If it reports 475 mA, your device thinks it's connected to a USB charger for some reason.

The problem is people keep on coming from other devices, and they've been trained so long by HTC devices (most of which use coulomb counter fuel gauges) that they need to "recalibrate" their battery and let it "settle in".
Note that the GSII may also require battery calibration - it does have an updated fuel gauge chipset. But ours does not.

12 to 13 % in 30 mins, ie 4 hours to full charge, that is the problem...

Is it the same with phone off and charging as with phone on
and charging
Sent from my SAMSUNG-SGH-I997 using XDA App

Phone asleep and charging and phone completely off should be fine. Phone in use will take longer.
Also, the reason I said to measure at less than 80% is because as you reach 85-90%, you hit 4.2 volts and the charge circuit goes into constant-voltage mode - in this region, charging takes longer.
Measuring time to go 10-15% is WAY too inaccurate for any remotely decent estimate of total recharge time. ESPECIALLY if that 10-15% is near the top of the battery. Our fuel gauge probably has on the order of +- 3-4% error. For example, once I saw it drop 10% in 30 minutes, but then it recharged 10% in only 5 minutes. The 10% "drop" wasn't real.

[Q] is this battery life normal?

i have the dual sim version. both 2g. NO WI-FI AT ALL.
I usually get 3- 4 hours of screen on time. then im under 14% i just use whatsapp, a little gaming,opera mini browser. with this usage i get total 14-18 hours of battery. is this normal? my previous phone was nokua 5230 with inane battery life.

not sure..
My battery life is better i think but cant say if yours is normal ... Screenshot of battery stats would be helpful

I charged in the middle upto 80. Screen on time at that time was 3.5 hours

Hmm..your battery life doesnt seem Bad to me, but I cant tell you if its actually a normal or a Bad battery life as i have the single sim Version with tweaky one Rom and faux kernel... Sorry, that i cant tell you more, but i saw some battery threads here at xda already, maybe you should ask there. Good Luck.

1. From screenshot it says 3G.. You sure you are on 2G all the time or this was just rare case?
2.From graph it seems like you charged phone in between from pretty low to quite respectable 70 - 80%.
3. I get this kind of battery on medium usage with single charge. So if you charged in between then your battery seems poor.
4. Do check background services running and disable what you can.. From usage you specified, you should not require many running things. Use greenify to automate this things.

He says he uses WhatsApp as well? Does it work on 2G connection too?. Thought I'd point out.

i had acdisplay but i dont use it now because i think it's eating up my battery. i have avast free, messenger, WhatsApp, clean master, dashclock widget and battery extenson . camera 360 is a bit nuisance. i close it but it starts again. also u should know that my phone was fully discharged two times when it was new
due to my carelessness. but i immediately charged it.
edit: also chrome on 2g takes up 1 or 2% every 3 or 4 minutes. it takes 3 or more hours to completely charge it with Motorola charger. I'm on GEL. got it from android police.

[Q] How to Determine Battery Wear?

So, I'm pretty sure I've damaged my battery. I've constantly let it get down to 0%, let it sit there way longer than I should, etc. Basically, I've just treated it poorly and have been experiencing relatively poor battery life (relative to the first month or two owning the device) despite greenifying, having low brightness, using Franco's kernel, checking BBS/Gsam, etc.
My question is, is there a way to determine the actual wear on our device's battery? If it's significant, I plan to replace it. If not, I'll just deal and look into anything else that might be causing it.
Thanks in advance!
Just as a disclaimer:
I am NOT saying my battery is not calibrated or any of that already disproven/discussed nonsense

The Nexus 5 has a Lithium-Polymer battery, if you discharge one of those COMPLETELY it'll end up dead/damaged. Probably what the OP is worried about.
The battery percentage is a calculation based on usage over time / system set battery capacity, not real capacity. When it shows 1% in Android, realistically it probably has 5-10% left. System will shut itself off before battery is harmed from excessive discharge in most cases. There are ways to disable the shutdown when it hits the calculated 0%, but obviously, such a thing is stupid and rarely done.
I'd say your battery is fine, OP.

Just don't repetitively attempt to turn the phone on again and again when it shuts itself off at calculated 0%.. that would be another way to hit actual 0% and damage the battery. (not sure if there's any protection against this, obviously not a good idea to try anyways)
But really, don't worry about damaging the battery by "draining" it to calculated 0%.

Battery issue

Hi, two weeks ago I flashed the cm, then battery started to drop by 2% and very quickly..i tried also mokee..same problem, so i restored the multi that i had before having the issue. But it didn't solve, so now the battery drops very quick..any advice..?

you can try to calibrate your battery, search store

I've already tried but it didn't solve

Many things can cause battery drain, the music player, your settings, depends on type of use, bad cell reception, etc.

Right.
And i too have the 2% drops often, but there for when i use it, it stays 10 minutes on the same %, so no problem. For me its normal to lose 1% battery for 5 minutes screen on. So i don't care if it stays 10 minutes on the same % and then drops 2%

Apparently according to a Google employee, those apps are absolutely useless as they only delete some log files, so it doesn't really affect the battery life at all. Can't provide a source right now, but you can easily google it.

The battery "calibrates" itself automatically when you charge over 90%. In other words, the batterystats file is resettet, the same what these apps are doing.

[WORKAROUND][SamPWND] Charge to 100% Snapdragon Root

I was able to find a workaround for the battery percentage:
1. FIRST Get your battery capacity!!!
$ adb shell cat /sys/class/power_supply/battery/batt_capacity_max
800
2. Calculate your 100%
800 * 1.2 = 960
3a. Charge battery fully (UI will say 80%):
Use your new 100% value in place of my 960!!
adb shell
$ su
# echo 960 > /sys/class/power_supply/battery/batt_capacity_max
3b. To revert back (and see actual %):
put your old value in place of my 800 here
adb shell
$ su
# echo 800 > /sys/class/power_supply/battery/batt_capacity_max
Warning:
This is not persistent across reboots (but could be implemented as such)
This does not change the fact that your battery meter will say 80%
This confuses your phone into thinking the 80% limit is higher than it actually is
This could be harmful to your battery life, battery condition, and battery operation
The Control Chip on the battery itself should prevent any unnecessary charging from occurring
I'm just a guy on the internet, don't mess with your phone unless your are willing to pay for any mistakes.
How this works:
The Kernel reads the battery percentage from /sys/class/power_supply/battery/capacity
We make the maximum battery capacity increase by 20% /sys/class/power_supply/battery/batt_capacity_max (the commands above)
Kernel reads the battery percentage from /sys/class/power_supply/battery/capacity again and its now 20% lower because of capacity calculations (percentage = used capacity / batt_capacity_max)
Kernel lets the charging continue to 80% which is in actuality 100%
FAQ
Does this work?
Yes this works. The explanation is above. Succinctly, these commands trick your kernel into thinking the 80% limit is at 100% of the battery.​
Shouldn't we be adding 25% to reach 100% of the battery?
While this is correct, I tested a few percentages and noted that 20% increase will reach 99% battery on my phone. This does not mean it will for everyone. PLEASE BE COGNIZANT OF OVERCHARGING​
This isn't working for me, why do the values change?
You must be a superuser in the terminal for these commands to stick. They do not stick across reboots.​
This still doesn't work, wah wah wah. I wan't 100%...
I am trying to help the community. If you don't want help you can keep the 80% charge. Multiple people have said it works. If you don't want to try it don't. Blindly saying it doesn't work is only poisoning the well.​

But does it actually go to 100?

If you do step 3b after you charge to 80% it will change to say 100%.
Steps 1,2,3a will bring you to 100% charge physically; almost as if the battery meter was designed to go 0-80
Note: this charges to your battery maximum (regardless of what percentage it says)

Yours may be different. It's based off your battery stats. And it should only be 20% increase.

Yes but you're multiplying 20% of 80 which is incorrect, that only gives you 96% not 100%.
If you subtract 20% from 1000 you get 800, but when you add 20% to 800 its 960, get it?

That's the thing, The 800 value has nothing to do with percentage. It's variable across devices and its coincidence thats its 800.

So is it really 100 or just the image of it

It really is 100%.

Hmmm. Have you battery life changed in any way? Just got me excited

i bit the bullet on this and went for it. everything seems to be fine so far. my max_batt_capacity value was 885, so 100% would be 1062, however, i backed it off to 1000, just to be safe. will update after tomorrow.

If A is the number we want the phone to charge the battery to, and the phone stops charging at 80% of A, the number we need to set A to is A * 1.25 , not A * 1.2
So, if the original number is 800, we need to set it to 1000, since the phone will calculate 80% of 1000 to allow it to be charged until 800.
Does that make sense?

So you are effectively increasing the battery capacity of an s8 by 600 mah and s8+ by 700 mah? Am I understanding this thread correctly? If so this seems like a huge problem waiting to happen.

no, this is a work around after using the SAMpwned root method, which caps the battery life at 80% of max.

Lol I have a feeling we are gonna see some batteries exploding again, lol

I'm still on the stock rom and unrooted and the stock valve in the batt_capacity_max file is 990

great find! i figured it had something to do with that file but wasnt sure how it was calculated as mine says 1000 but others was different lol..
but our idea was if this was in fact the case that you create an init.d script that runs on each boot that will automagically correct it each time you reboot the phone

actually, changing that file instantly changes back to its original setting for me

One thing that I didn't get.
Okay, the phone will think the maximum is 1000 and will try to charge the battery up to 800, which is the real target. Great.
The screenshot, though, shows the indicator on the notification bar close to 100%, in the rooted phone.
So, the routine that checks the phone charge and limits it to 80% is independent from the check embedded on the indicator charge, right? Otherwise the indicator would never reach 100% even on the rooted phone, and even though the battery was actually 100% charged.
