Battery consumption

Hello everyone,
I'm running some tests to see the battery consumption on my Galaxy S i9000. I'm using the gingerbread version of darkys ROM.
Firstly, what do you think of the battery life? In this specific test I used the phone in a very light way, made some messages/calls and read few mails.
Secondly, is it normal to have depressions in the battery chart that display less battery than it shows later? How is it computed? Isn't just some logic level of the voltage battery?
Lastly, in the case of buying another battery, is it worthless to be genuine?
Thanks a lot

Battery must be recalibrated on each rom update?

Hi every one,
I was wondering if there is need to recalibrate the battery on each rom update, custom and lg official releases?
Also i bought a 1900mAh battery so I think it need to calibrated for better performance?
Any advice will be great

no.
Battery calibration does not affect battery performance, it just changes the accuracy of the battery %age display. There is also no way of calibrating the battery, as it is directly read from the li-ion battery itself. Deleting the batterystats.bin Does nothing besides resetting androids About Phone>Battery Use data - which already resets itself on a full charge (And also broken on O3D GB Roms)
Its actually likely that calibrating the continually will eventually result in considerably worse battery life, as li-ion batteries are best operated between 20-80% charge.

I saw on the battery calibration app, that it must be recalibrated, since each rom has diferent files to manage power, and it will actually help the battery managment.
Thats what i know, im not an Expert.

I saw that too, on battery Calibration by NEMA it says:
calibration needs to be done after flashing a new ROM. but you calibrate.. etc. the whole message that why my initial post was about, I saw other posts saynig that it must so ill do it just in case I dont think that will do anyharm at all.

wasn´t calibration just a matter of charging till 100% when off, then remove battery, insert battery and then start phone and plug again??
i do this and my battery it's all good, although i cna't watch a video for more than 3 hrs hahahaha

It actually worked on my ZTE Blade. I believe it's called overcharging.

hi
i dont think so need callibration after each new rom!
it might harmful for battery!

[Question] Battery % issue on our G3

On every rom i port, why does our g3 do not show correct battery % values.
What is the use of one % battery mode if it does not show correct values.
Is there any solution? Or any developer who can make our g3 to show each % of battery accurately.

buddy, i just wanna inform you...you missed section.....and....battery indicator depens on a kernel you use aswell....as cm7 kernels...(some of them)...have that bug...but not g3mod....so...

Thanq for ur reply Rkoby...I know that battery % depends on kernel.
Not only in cm7 kernels but also in froyo kernels and roms after charging to 100%, in just 5 min battery level gets down to 32% or 28% even if we dont use the phone and after that it takes a day to get down to 12% then another day gets down to 5% and then i have to charge my phone.
Even on g3mod kernel.

What i need is battery % should be accurate to its each value.
Can any one suggest me any froyo kernel which shows battery % correctly.

Fugumod kernel, probably....

Sorry guys actually it was fault of my battery.
I baught a new one and it is fine now.

Few more questions to ask.
1. I have got my new battery in a plastic cover.....so I wanted to know wether it is better to use the battery along with the cover.
2. Does overclocking spoils the battery.
3. Few more tips so that batter would last longer [for many years].
Sent from my first smart phone

I think it is better to remove plastic cover as it would just act as an insulator and heat the battery.
Regarding better battery life you can try using profiles in set CPU to increase your battery life as well reduce overall lag.
You can overclock whenever your apps demand more processing like heavy games etc.
Sent from my GT-I5800

Basics 101 no one makes a product to last "many years". If ppl dont come back for more most companies will have to shut down shop. Max you can expect is 1-3 years.
Some things you can do ensure longer battery life are:
1) Make sure you calibrate your battery once in month or 3 months.
2) Avoid completely draining you battery often.
3) ensure first charge of about 6-8 hrs with the phone switched off
Apart from this you can also set up some Profiles in set cpu to underclock your processor @night or when screen is off to reduce power consumption.

Sorry dude I misinterpreted your question
In order to get the battery running for many years never let the phone be plugged in to charger once it is fully charged (like leaving it to power source all night). This is common cause of batteries dying earlier

Yes......it is good to unplug the charger as soon as it gets charged.

[Q] i9000 battery on i9003

I have a very simple question
Will there be any problem if i swap my stock i9003 1650mah battery with the 1500 mah battery of the i9000
will any issues pop up due to lower power or anything?

i dont think theres gonna be a problem. maybe your only problem is lack of 150mah..thats all..the important thing is the battery fits..
Sent from my GT-I9003 using xda app-developers app

No, absolutely no problem. The two batteries have the same voltage and output current, so there's no difference but the capacity of the battery.
Cheers

Battery Reviews

I just was seeing what kind of interest there is to having some battery reviews/tests conducted by me, I did a whole bunch for the Samsung Epic 4G years back and some for my recently traded Stratosphere II (RIP last of the great keyboard phones....), I'm looking for the best battery life possible and coming from a fat battery on my Epic and Stratosphere II the S5 is clearly lacking in the battery life department.
I was wondering if anyone wanted me to do tests on their batteries new or old (the newer the better though, for fairness and the best possible comparison). I'll eventually have up my S5's battery, aged as old as my S5 is (unknown really since I bought it off Swappa but we could see how much the cell has degraded and how much capacity has been retained)
Feel free to check out my review page from the Epic in my signature to get a gist of how I usually conduct em!

Hi can you please test with the KT kernel with fast charge enabled and let us how much time it is taking to fully charge s5

How would you like me to measure the time and from what minimum battery percentage?
Usually I test the batteries externally with my usb battery tester, just as a literal indicator of the discrete capacity of the battery, since there are too many kernel, rom, and setting configurations to accurately judge the best battery life/charging scenario on the phone. The battery capacity itself is not a variable so if it increases then the battery life (and charging duration) will increase by whatever percentage of extra capacity that battery gains over that one it's replacing.

Hi try to measure the time from 0 to 100 %

any one have more of 4 hour of screen usage ??? on lollipop ???

Other day: 6h20min SOT, battery 1day9hours 10% left, wifi/data/location on. 20min talk. But this was record.
Usually it is 4h30 - 5+h SOT
BOC7

I usually get between 4-5 hours of screen on time at work because of not the greatest reception, but on weekends when I'm mainly home with a strong Wi-Fi signal, I've been getting about 6 hours of SOT on lollipop. Battery life is better on lollipop than 4.4.4 for me.
