I use "battery Graph" to charge the battery and the charge held good at 70% for a very long time. Yesterday when it was in idle, it kept the charge for 8 hours during night at 70% and today five hours at 70% during night time. It also holds charge longer at 15%. I find Battery Graph is better in assessing the chage on the battery to last longer.

I've often wondered if that percentage was accessible to running programs or if it displays differently because the battery is being used differently when the percentage is being reported. When test mode is open, android isn't loaded at all... so it could be reporting differently just due to environmental issues. I've had many devices report battery percentage differently depending on what I was doing with the device at the time... this might be a similar effect.
Charging with Battery Graph gives the stepping up of charge and stepping down of charge. Even though the Phone says the battery is fully charged, the Battery Graph did not indicate full charge. I had to charge it for an extra half hour to get 100% charge. The battery is also subjected to cold weather condition and other electromagnetic radiation that may be beaming down anywhere out of blue. I pulled out the battery and found out that it doesn't have metal wrap or coating on the side of the battery. This may be the reason why the battery is discharging in a non-uniform fashion when no application is running in the background.
can you elaborate more? not sure if i missed a post way back? 15 pages is a lot to remember.
sorry.. the majority of the "techincal" stuff is going on at samsungmomentforum.com .. that is where i posted the majority of it..
Basically the way the samsung battery code reads.. it appears they coded 3.74V to report 15% battery capacity..
The nominal voltage of our battery is 3.7*V Basically when the battery is actually at anywhere around 60-40% capacity, the way it is coded it actually reads 15%.. This explains why once the phone hits 15% it last forever.. because it really isnt at 15%... We need to alter the s3c6410_battery.h and add more voltage steps between medium and low.. then recode the response levels..
found it cool:
Working on the battery issue... I think
lots of good work there man. very interesting why the programmer made that initial decision.
now the value at which the phone turns off is android or samsung based? meaning the time from phone fully charged to turning off wouldn't change correct? Just the meter would function better.
how would you modify this? something we'd have to load on the phones? I assume no one on that forum from samsung is listening.
This would be part of zefie's rom update that he has been releasing if the new code works.. TBONE did an awesome job modifying the code it looks like (i am a good debugger but when it comes to writing the code i suck)...
I wouldn't screw with the threshold voltages IMHO.. The time the phone stays on is dependent upon the voltage the battery is at and it turns off when it hits the minimum acceptable voltage which sammy has at 3.49V...
is the 3.49 a pretty standard value? my phone personally stays on so long not nec at 15% but at the 5% mark as well. would all those values get bounced out a bit?
Sorry i'm not as into the phone as i should be to be asking these questions, but "zefie's rom update" would that become an android app, or how does it get pushed to the phones. I assume its nothign to do with something samsung or sprint would be involved in, correct?
i know enough coding to follow all your guys logic. makes complete sense to me.
we didn't touch anything below 15% and don't plan on touching that stuff.. it gets really iffy due to how sharp the voltage drop occurs... All we are trying to do is make it a little more accurate from the 90-20ish range so it doesn't always just show 15%..
Also working on a way to actually make it show 2 digit percentages (98,97, 96, ect.) but have no idea how the battery meter is coded and if it relys on bat_lev.. we will find out when the code gets done maybe.. We just started on the battery meter program this afternoon
Zefie put ZE05 up and it contains the battery meter modification.. it is highly alpha right now (we have no idea how it will work in teh real world.. zef said he saw vast improvement on his).. We tweaked only the reporting voltage and didnt touch the charging portion of the code (didn't want to mess with step voltage charging on a lithium-ion battery)... hopefully it reports more accurate.. TRY IT AT YOUR OWN RISK!
I went immediately from 30% pre patch to 50% post patch and hit 60% after 1 minute on the charger... We are working on one that hopefully will do 2 digit readings instead of the integer of 10 that we have now..

Sprint or Samsung must put a firmware update as the phone seems to last for a relatively long time at 15%. The battery meter must be completely re-programmed so that the phone doesn't shut or or even FREEZE
by downloading a third party ROM update. Besides, Samsung or Sprint may supply a new battery with a good shielding from EMF such as in some high profile electronic equipments these days. The dischage of the battery is not uniform with no application running in the background and therefore it may not be really a battery meter issue. It could be that the battery molecules may not react as much to EMF radiations that may be coming from weather satellites etc., when it reaches to 15%.
Ever seen a battery without a metal sheilding these days
? The Samsung battery has no sheilding on the sides.

The discharge of the battery is erratic and all of a sudden with no application running in the background.
It may be a fact that EHF has effect on battery discharge and it may very well be advisable to have metal wrapping all around the battery just like ordinary batteries. The battery of Samsung Moment has no metal insulation on the side of the battery and thus it is susceptible for absorbing or reacting to EHF radiation from satellites such as weather satellites etc.
Just use commonsense. Why is it that ordinary battery manufactures do all that difficult task of metal wrapping on their batteries when they could have done it with hard plastic coating which will be cheaper for battery price. With frequencies such as 66 GHz even molecules could resonate causing battery discharge. The loss in energy by resonace
is perhaps used to get imaging and data aquisiton which is common in weather satellites. There are so many low orbit satellites these days that metal shielding all around the battery may be essential for a longer life

Besides, aluminum foils are not very effective in filtering out EHF as it seeps through any perforation as the propagation may be not like VHF or UHF.If the battery is made in such a way coated in metal or wrapped in metal non-perforated foil to protect EHF by only making connector face in plastic but protected by proxy by metal enclosure, the battery life will be much longer.
To tell a little more about this, it may be advisable to enclose the battery in a sound absorbing material as EHF may cause noise because it resonates molecules such as oxygen. This noise may be damaging to battery as well.
So when you see some nice electronics equipment with silver coating in a velvety chamber it not only looks nice but works well too.
These things are nothing new

Wouldn't it be great if people read at least a few pages of this thread before commenting or asking the same questions over and over again?
I've had my Moment for a few days now. Battery meter showed drainage to last 6hrs of use. Then it went down hill from then. Today, I took my phone off the charger, 3 hrs later in sleep mode (and everything off, gps, email, all background applications, etc) it was down to 40% in 3 hours. 2 hrs later it was down to 5% with no use.
So I started to google because I knew that wasn't right. And I didn't suspect the battery to be damaged or faulty, although it would be right to suspect.
I "drained" the battery until the phone "shut off", I then put the phone into "test" mode by pressing "talk, middle button and end" buttons at the same time. That brought up a test screen.
I then checked the battery status which showed 0%. I then increased the brightness to "full" to "completely" drain the phone. About 10 minutes later, it made a beep and shut off. I tried to turn it on again, both ways, and nothing. So now I know it's "drained" to the extent I can make it drain.
I will now recharge it to full to see if anything changes.
-----------------------
My wife's phone on the other hand is showing 60% 7hrs after unplugging. We'll see if that will change or not.
The problem with the meter is, if it shows 5-10% or less of charge, it will not let me make a phone call. And that's unacceptable.
I will update on my phone charge status.

Draining it fully and recharging it fully wont really make much of a difference in the end with respect to the battery meter...
This is why I mentioned that the discharge is not uniform when no application is running in the background. My phone stays at 70% for 5 hours and after that very long at 15%. I use Battery Graph to charge and realized that even though Samsung says the battery is fully charged, the Batteery Graph only shows 90%. So, I kept charging until the Battery Graph says 100%.
Someone mentioned that this battery doesn't have a memory. But, when I recharge the battery from 70% to 100% and then uppugging it overnight, the battery Graph shows I have about 80% left in the morning. Mind you that I am using a program to suspend many fancy programs when the phone goes to sleep.
The weather reporting widgets that use GPS ruins the battery life. I hate running any low orbit satellite applications when the phone is sitting idle.
I am happy with my Samsung but they could have designed a better battery in view of todays interferences and possibly experiments.
Note battery graph is nothiing more then a guess based upon how long the battery has been on for and when it "hits" 100% and how long it takes each time from unplug to plug and then plug to 100% it attempts to determine how much of the battery you used during the unplug period and plot that over the time it was unplugged for.. Problem is the default samsung code doesn't output correct adc values (which is converted to voltage of phone).. It is a problem with the software only, the battery has nothing to do with it..

Are you confusing "Battery Graph" with "Battery Left"? It almost sounds like it. I wouldn't even say that Battery Graph takes a guess... in its graph area it just plots where the battery meter was at any given hour in the portion of the history you're viewing, according to what the OS is reporting.
Either way.. with the stock kernel it isn't going to work if it is basing it off the OS reporting values..
Hell agent i believe you are running ze08 now arent you? Should notice a little bit of a difference..

Update:
Since I have "fully discharged" my battery, (from phone turning off to putting it into test mode until it turned off that way also).
It has now been about 10hrs since last charge (regular charger). The phone shows 70% battery life. (light use). If that's the case, I could get 30hrs with light use. Glad this fixed the problem.
I think that some people may not be "fully" discharging their battery. Fully discharging means to have the phone turn off, then also have it turn off in test mode.
For the people that still can't figure out "this" problem. I suggest making it simple; read this WHOLE THREAD.
NEW UPDATE: 01/05/2010 8pmCentral
My phone has been on for a total of 28hrs. The battery meter in the phone info was very different from the "test menu" into and very different from the main screen info. All three showed different battery %.
This was very light use. I bet it's the stupid applications that you "cant uninstall" that are running the battery dry. This phone won't even last past 28hrs on standby, it's a joke.
ON THE OTHER HAND. My wife's phone after a full recharge, only lasted 9hrs. Before, it lasted longer. So, I'm going to assume that with every recharge, the charge will vary from 6 to 28 hrs.
Samsung is like AT&T, in denial about their products. How do these morons not test out their products before putting them out on the market?? Instead of making the current phone's better, they make new ones that suck.
I'm thinking of selling this and waiting for the new google phone, that's slimmer and has a promised battery life.
