New Battery for Tilt running Polymod 2.1 Eclair - Tilt, TyTN II, MDA Vario III Android Development

Hey all,
I just bought a new battery for my Tilt running Eclair polymod 2.1g in NAND, and was wondering what the recommendation is for how to initially charge this battery to a full-charge so that Android recognizes it.
Should I reflash a WM rom to charge the battery fully before running Android?
Thanks.

Well, if you want to give your battery the best chance of getting a full charge with as few issues as possible, I would go for the WinMo option. There a couple of issues and problems with getting the calibration to work right in the current (and even all the ones before that, walking back to 1.5 and 1.6) builds of Android that seem to mess the charging up.
Now, I'm not a dev of the different kernels and drivers or anything like that but I'm pretty certain that if you give your battery the best possible charge through WinMo, you will at least have done what you can. Other than that, the battery seems to charge just fine most of the times in Android, but the calibration of the charge level is very twitchy and in-concise, which can make for all sorts of odd status reports from the battery level in Android.
There are discussions about this topic all over this Android forum and you should be able to pick those up around here, but these are my 0.02 SEK in the matter.

I'm not so sure if Android really messes up the charging. It may look like that like when the battery indicator indicates full charge even when it's not but if you run dmesg in a terminal you will see that it still charges and the mW increases. So perhaps it's charging allright even if it doesn't look like that.
A wall charger charges with higher current than using the USB-port from a computer. At least that's the case for me (450-480mA with wall charger and 200-300 mA with USB-port). Keep a terminal open and run dmesg every now and then and when the mW stops increasing and the mA is low (don't remember exactly how low the mA gets but I think it may stop at 10-20 mA when it's fully charged) it should be fully charged.
I had my battery indicator showing 100/100 when it's was only half charged after an Android NAND flash but dmesg told me it was charging anyway and when it was done charging I deleted /data/system/batterystats.bin and after that the indicator seems to work rather well.
EDIT: Just checked. My mA seems to stop around 6-8mA when it's fully charged.
EDIT2: Waiting a little longer it actually drops down to 0mA

All my tests at work show no real difference between charging the battery in winmo or android, a full battery is a full battery, and both os seem to charge the batteries I have tried to about the same levels.
The real difference is in the way that winmo and android interpret the data, android still seems to have some issues when it comes to working out how much actual charge is in the battery, and consequently the displayed percentage may be inaccurate. In reality I find that android does indeed consume more power than winmo, however,over time android seems to get more accurate, and at the moment my perceived percentage seems to be on par with androids estimate.
So to answer the question.... Charge it as you would any other battery, just remember that your displayed battery figure may be off a little to start with, with repeated charge-discharge cycles this should improve.
Oh and go look for 'OSmonitor' on the market, since it has few handy functions for keeping an eye on various system parameters, and is great for checking the battery messages

Battery Problem After Upgrade Black+radio

got problem iv upgrade my phone to black 2.5 and upgrade the radio to 1.41
now my battery finish after 8 houres(always after 3 days)
i dont use mach the phone so the battery not good now
i want to konw is this can be cause the upgrade to black or because i upgrade the radio freom 1.38 to 1.41
what can cause it?
It would be helpful to know which operator you have...
But, try different radios. It seems that radios have a more significant impact on battery life in general.
Ok Thanks I Had Black 2.0 Was Very Good
And I Had Radio 1.30
Iv Got Spl 2.10 And Jasjam
I Guess Ill Put Back Radio 1.38
Was Best For Me
Great. Let us know if that sorts your problem.
I had the same problem with my battery after flashing Black 2.0, and subsequently 2.5
It was because when i flashed the Hermes to WM6 it was only at 50% battery life. WM6 must recalculate the battery at 50% battery life to 100%. Hence my battery was screwed only ever charging to 50%, but WM6 assumed it was 100%
ended up getting a 2400mAh replacement of ebay
Sweet. Nice info skip. Did you have to get a case for that phone with the new battery? I was looking into getting one but I didnt know what phone case supports the bigger battery. Any suggestions?
I had the same problem only after flashing to Black 2.5. The phone would be dead after about 8 hrs using pushmail all day.
Anyway, my "fix" was to pull the battery, then pop it back in and charge without turning the phone on. That way, the OS wasn't running, and only the internal phone charger was in charge of regulating the power, at least that is my guess.
Anyway, after one session of that, it has been fine. Give that a try and see if that fixes the half charges you're getting.

I tried "resetting" the battery like that but left out a step...will try that and see. Did you run it dead or can you start the process when the battery is at say 50%?

hmm. I have same problem with battery. my battery barely lasts one full day and before the upgrade i used to charge once in 2 days. Do you guys really think the battery level matters when flashing?

Thanks. My battery was still pretty good, but not "great". I assumed some settings changes effected it. I did this and it is lasting longer. With all the "HELP!!! ROM KILLED MY BATTERY" type posts, this is a GREAT find. Thanks.

Im not convinced, would be a VERY weird way of calculating battery levels and would totally rely on the user having 100% when the OS is flashed.
My bet would be that the new Radio is causing some problems, or even further the problem might be caused by 3rd party software (which ive seen MANY times).
Maybe you could solve that issue by using an external charger. Get the battery up to 100% again. This might persuade the Tytn to recalibrate.

I have had the same problem with Battery life after upgrading to Black 2.5 and radio 1.41. Unfortunately I upgraded both the ROM and the Radio at the same time, so I could not identify where the problem came from.
From reading comments on radio 1.41, most users seem to report improved battery life over earlier radios.
My battery was approximately 60% when I upgraded the Radio and ROM. I am going to try the battery charging trick mentioned above tonight and see if it helps.
yep, will pop the original battery in and try charging it without turning on
The ROM doesn't matter. Most all lithium powered devices with a batter meter use smart chips to monitor current into and out from the battery to give battery status. They all get slowly out of calibration over time with many partial charge/discharge cycles typical to phones and light duty use. The best way to calibrate them in a phone would be to pull the battery, then re-insert it and charge it fully. Much of the commercial gear (medical) that I use is calibrated by running fully down, then recharge to full to re-set the meter calculator. These batteries do have the smart chips in the pack.
Lithiums are very specific on charge voltage as well, 4.2v per cell at full charge and 3.0 considered fully discharged (any lower and the battery is toast, most devices shutdown to prevent over discharge).
A simpler device might just measure the battery voltage alone, then scaling the 3.0 to 4.2v output of the battery to a 0 to 100% reading. This type is most likely used in phones which have little to no active electronics in the packs themselves. PDA's use a mix I believe, as some software can be used to calculate runtimes based on realtime current drain.
Last but not least, lithiums simply have a shelf life of only a couple of years. In a phone, I'd say a year and they are already showing noticeably lower capacity.

Interesting theory and very educational. I would say that most people should come back saying the trick worked. I am actually going to try it myself because of the logic.
Thanks,
OK, just a little update:
It must be either Black 2.5 or the radio, i've tried default fresh installs with 3 differnet fully charged batteries, my original, the 2400mAh ebay one and a borrowed battery from a friends vario.
Im still getting major battery drain - a few hours in standby mode ?
gonna try upgrading to black 3.0 today
Same problem here, severe battery drain with Black 2.5 and radio 1.41. Tried the battery trick, doesn't seem to work for me.
Have tried multiple settings to preserve battery life, but no results yet. Started this morning, fully loaded, did about 30 phonecalls this morning and already 60% battery. Battery won't last till the end of the day.
I will install Black 3 tonight.
after upgrading to Black 3.0 im still getting this dreaded battery drain, Gonna try the radio
currently running 1.40.30.00 on T-mobile UK
goin to try upgrade to 1.41.00.10 and see if that helps
Can other users who suffer the battery drain please let me know what radio they are running?
Cheers

Battery Issues with any rom

I'm surprised that nobody is mentioning the poor battery performance on the tilt 2.
I'm at 50 percent already with 8 hours standby (sleeping) and 2 hours of work.
I have my email update after every 15 minutes, and bluetooth on. No wifi.
Is it just this device or the ROM. I'd rather not say the ROM to implicate, but can we get an honest evaluation from Touch Pro users about how long their batteries are lasting??? Please.
hi, battery calibrations are lost when flashing roms. It is said to take a full discharge and full uninterrupted charge to restore these calibrations which cause reduced battery performance and also using the phone for a few days also helps too. I admit I would like to see better battery life generally, but its the price we have to pay for such a feature-rich amazing device.
Things like Lumous (auto back light software) can help out controlling how bright the backlight shines in certain scenarios. Setting backlight to switch off after 10 seconds and device to sleep after a minute can help out too along with not having 3G connected when not needed as with data connection, bluetooth, wifi etc.
Hope this helps out.
in regard sto battery calibrations, I have done that, and i have been with the same rom for 5 days
hmmm yeah I do know what you mean though about the performance of it, perhaps invest in a new battery, an extended one maybe? My TP2 lasts on average 2-3 days with some music playing, weather updating, not much calling, alot of texting and maybe some internet use.
same battery issues here with 6.5 stock rom but after hard reset
battery live is 30 hours with stil 2 stripes on batt indicator
pres green-red button-powerbutton read the message and then volume up.
Oh and I think the first battery loading is done 2 quickly the green Indicator after 1.5 hour was green < hold the device loading for 4 hours
yea i always perform a hard reset after flashing a new rom, i personally find the full discharge and recharge a good way to get things back to normal. However currently experiencing a max reading of 99% despite green light and it stopping charging. Have let it fully discharge until it turns off, and then left the device in bootloader to make sure the battery is completely dead and left it charge overnight but yet still only get such a reading. Perhaps when I flash an updated rom the reinstall may restore (which won't be too far away I'm sure, loving the Cell Pro series, thanks Sergio!)
There are a lot of reasons for the battery life to go down quickly. I have used many different ROMs (mostly cooked ones from the chiefs here) and have not found a lot of difference in my battery performance. It has been noted somewhere on this forum (room-mate read it somewhere here) that the stock radio on the tilt2 seems to be best battery life for most who have used it.
So to sum some things up:
- Version of radio
- how bright the screen is kept at all times
- number of applications running all the time (including auto updates for stocks, weather, push web pages, etc.)
- Temperature (going from a warm house to the cold outdoors)
- speed of processor
- size of screen/resolution
can all lead to shorter battery life.
Living in a rural area vs. downtown in a major city can also greatly affect your battery life. Most buildings will have cellular devices attached to them as companies receive some money from cellular companies for hosting their equipment. So battery life is much better downtown as the phone does not have to search as much for a lock on a good signal.

Never fully discharge the battery! Most all devices will use Li-lon batteries and when over charged or fully drained you can kill the battery. Most devices are intelligent enough to charge up to (approximately) 98% and only let the battery drop to no less than 2% of life before shutting off. I used to do support for HP notebooks, and when they introduced lithium-ion batteries, people would demand a new battery when it would not charge past 98%. This made them change the way the software was reading the battery to reflect the 98% to read 100% on a full charge.
There is a good link in the wiki for our phones... I'll give it free of charge this time: http://forum.xda-developers.com/showthread.php?t=519673

[REQ] App to Measure True Battery Charging Level

As you all know, the Evo battery charging mechanism is very quirky. If you are using the stock battery, the mechanism is not THAT bad once you understand how it works. If, like me, you are using the 3500 battery, charging the battery in the Evo is pretty much futile. Reason being, for some reason the Evo still thinks it is charging the stock battery despite the fact that you have a battery that is 2.5 the capacity in it. What this means is, the fully charged green light comes on at about the 65% level and you ultimately have to play a guessing game as to when the battery is actually charged. This is also after calibrating and wiping stats and doing whatever dumb HTC/sprint charging "trick" out there.
I am pleading here for someone to create an app that measures the true capacity and charge level of the battery so that we can all, especially extended battery users, know when the battery is actually fully charged. I am positive that there are donations in the project as this app will benefit all Evo users.
Please help and thanks in advance.
+1
I've been looking at the 3500mAh batteries as well, would love to get one, but i flat refuse to pry open my Evo everytime I want a FULL charge (having to resort to wall charging)
I'm not an expert in electrical engineering at all but I'm going to make an educated guess that the charging circuitry is independant of anything that the OS itself can control. Even with the phone 100% off it still has to obey the "rules" of charging that HTC setup. (i.e. charging to 100% then running off battery till it hits 90%) So I don't see how there can be an easy workaround for extended battery users if they want a true 100% charge.
I'd love a bit more juice myself, but like I said the only time I want to have to open up the back is if im upgrading my mSD card. If and until someone can come up with a solution, hell yeah! Until then I will just play with juice defender and hone my battery saving ability via software
I know the Battery Time app you can put in how big your battery is. Just select other when choosing your phone.
Sent from my PC36100 using XDA App
in for progress on this.
so tell me even though the phone thinks the battery is charged, does it stop charging it too?
If I remember correctly that may have to be done in the ROM/kernel, there is most likely a charging timer somewhere in there that stops it for safety reasons.
When changing the timer remember that the batteries are actually closer to 2800mAh than 3500, you don't want to overcharge it.

No it continues to charge which is even more nonsensical and adds to the frustrating guessing game. Seidio recommends that you keep the phone on the charger for 2-3 hours passed the time that the light turns green. Again, more guess work.

I think you are referring to wiping battery stats. I have tried this on several Roms and kernels to no avail. Also, if you aren't rooted, how would you go about wiping stats? An app would help a lot of people out.
Also after doing some more research and testing, any app that provides battery level that I have used including OS monitor, spare parts, etc. will basically spit out what the OS is telling it and not measure the true level. Unfortunatley, the OS is stuck on stupid and we are back to the original issue.

I don't believe it is possible for an app to do what you are wanting, the charging process is controlled by the operating system itself and is built into the kernel.
There are two main steps to charging a li-ion and the first one finishes when the battery is around 70% full. So either something is causing the phone not to start the second part of the process, it is just timing out thinking that battery should have been by that time, or, since the batteries have circuitry inside of them, it could be the battery itself that is doing it. Have you tried charging your phone through your USB port? It takes longer but the battery may not like how much power the wall charger pushes through it.
Edit: I think I misread your OP, does your phone stop charging when it says it's full or does it keep charging?

The phone continues to charge. Based on what you are saying and my own findings, it seems the phone is reporting that initial charge at 70% as 100% when using the 3500 battery.
I am in the midst of testing some things right now related to all of this and will report back.

Thanks keep us up to date. I bought this battery too so very interested in any possible solution you find.
Basically the os says its 100% when in reality its not even close, more like 65% right?

Yes. 10char.
how does the phone read the charge or does it?
maybe a glitch in regulating the flow?
any software determine could do this?
mine charges a good 8-10 hrs a night
never had a phone that needed more
anyone had to buy a standard battery replacement and get better battery?
software or hardware?

Looks like I failed again. This issue really needs attention from someone well versed with how the Evo charges the battery and how to tweak the reporting deep in the android system. Wiping battery stats in recovery does not solve this issue. We need a SetBat!
I got curious so I looked at the evo's source and found that it stops charging when it thinks the battery is full and doesn't start again until it drops down to 80%. Although it should start charging again if you unplug it and then plug it back in. To fix it you will need someone to make drivers for your battery and incorporate it into a ROM.
Sorry I can't help more but compiling ROMs is still a little bit over my head right now.

Very interesting. The problem here is, the Evo stops charging when it thinks the stock battery is at 100 even though you have an extended battery in it.
I guess we would need a talented dev to compile a fix. Hoping that this thread can bring some attention to that. Looks like we have progress already!
Here are my findings from the monitoring I was doing earlier. It's a lazy Saturday for me so I actually had the time to watch the battery charge. For background info, I am using CM6RC2 and Snap 7.01 with the Seidio 3500 battery.
I let my battery deplete completely last night and woke up to charge it. Knowing full well that the Evo does not charge the battery correctly, I did some research into how I could properly monitor the charge on my own. What we are basically looking to do is to charge the battery to or close to 4.2v. You can monitor this yourself using any battery monitoring program. I was using spare parts.
What I saw was, the battery would charge to what the Evo thought was 100 or close to 100 for the stock 1500 battery, the green light came on and the reporting stats of charge/voltage stopped there. The phone was reporting a constant charge of 100 and the voltage froze at 3.9v despite the fact that the battery was actually charged to around 60-65%. These numbers froze there for a long period of time. The 100/green light never went away and the freeze in voltage reporting lasted about 1+ hours. The freeze at 3.9v was basically the OS reporting the 3.9v in error because it still was thinking that the stock battery was in the phone. The actual battery charge level was neither 100 nor 3.9 volts. Like I said, the voltage stayed at 3.9 for a while, lets say an hour+, and then it started charging up again to 4.2. I saw all of this happen in spare parts. The highest I saw the voltage get was 4207. It took around 5 hours to get to this point. Once it was close enough to 4.2, I rebooted into recovery and wiped my battery stats using Clockwork. On reboot, the battery was actually around 95%. Now I could have plugged the phone back in and repeated they process above but, as this point I basically gave up knowing that I couldn't really go through this type of process ever again because I never have time to sit there and watch a battery charge.
So back to point of this post, we need someone to find a way to have the Evo report true battery stats for extended batteries and not continually have the phone think that it is charging the stock battery. I don't know if it can be done in an app, in a rom, or in a kernel but, however we can get this done, it would be more than amazing.
I have never had a problem with my 3500 Seidio Battery in terms of charging.
I have never had less than 90% charge when I leave for work. But as it has been pointed out multiple times, this phone charges till 100% and then works off the battery until it hits 90%. In essence, this phone will never be charged to 100% unless you do it while turned off or quite possibly with the battery out of the phone.
Next time you think you don't have a full charge, take it off the charger, turn it off and then back on. Then stick it back on the charger, you will see that the charge is down to say.... 93% then it should start charging again. But too be honest, on a 3500mAh Battery, I really don't see the need. If you really need 100%, the best way to achieve this is with the phone turned off.
there are people in evo forums across the net that would donate en masse for this once word spreads. if it needs to be unique to each battery, the four most used are stock, 1750, 3000 chinese (what I have), and 3500 seidio. I would definitely donate for a true fix

Then stick it back on the charger, you will see that the charge is down to say.... 93% then it should start charging again. But too be honest, on a 3500mAh Battery, I really don't see the need. If you really need 100%, the best way to achieve this is with the phone turned off.

I assume that you keep your phone charging all night?
If so, this isn't really for people who do that. This is more for people looking to charger their phone to at or near 100 on the go, at work, etc.
Also, 10% on the extended battery is probably a difference of at least an hour more battery. I'd say even more. That's a lot of time to me personally.

there are people in evo forums across the net that would donate en masse for this once word spreads. if it needs to be unique to each battery, the four most used are stock, 1750, 3000 chinese (what I have), and 3500 seidio. I would definitely donate for a true fix

Agreed. I'd rather donate money to a true fix than buy an external charger. I have funds to donate for this READY TO GO ASAP.
I think this is a firmware related issue.. I cannot count how many posts and different senarios (batteries, chargers, rom's) I have read, yet still this issue remains. The only things I have ran across that actually works is:
1. Charging the battery externally (wall charger, dock, or etc)
2. Charging phone while phone is turned off.
3. Bump charging (aka: battery conditioning, battery syncing, "plug/unplug method")
4. Clearing the battery stats

Evo not charging,or taking very long to charge

Ever since I flashed Ultimate Droids Rom my battery has started to take alot longer to charge. I throw it on the charger at 6%, and check half an hour later to see that its gone up maybe 1% or none!
I've tried to nandroid to past Roms that haven't had this problem but they all seem to be the same.
Could it be my Evo,or my Battery?,

It might not be your battery nor your phone. It might just be the rom you put. take it off and then see if your battery improves. If you know someone who has an evo, maybe an incredible since it uses the same battery try putting theirs in and see if it makes a difference. That way it will save you some time from completely restoring the rom.
Okay I'm pissed off. I took my phone off this morning at 28% ,so I throw it on the charger turned OFF,30 minutes later 8% l
WTF is happening!?

You are being punished for being a bad person.
Lol, seriously, my guess is any number of things:
1) Check to make sure your red charging light comes on when you plug in.
2) Make sure your charger isn't plugged into a socket controlled by a lightswitch you have turned off.
3) Make sure there are no micro-breaks in your charging cord's casing that would be causing a short (this happened to me - got new charging cord, problem solved).
4) Make sure your charger is rated at at least 5 volt / 800 ma.
5) Your usb port may have gone bad.
6) Go into Clockwork Recovery and clear your battery stats under "Advanced Options".
7) Your battery is cooked (happens - hardware breaks).
8) It could just be a coincidence that this is happening to you after you flashed UD. I was just over at their forum and this doesn't seem to be a common problem.
I have an EVO and am running the UD 12/3 nightly and it is flawless. 2.3 was a bit buggy. The new nightly is better.
same problem
Has any one figured out what's the problem with EVO and the battery charging situation? A couple weeks ago I noticed my battery wasn't charging, I turned the phone off and on then it would charge...now it won't charge at all WTF? I got a red light indicating my phone is plugged in, I got a thunder bolt in the battery window indicating charging, but the green bar is not moving while charging anymore. If I unplug the phone it will shut down. ANY AND SUGGESTIONS ARE WELCOMED...THANKS IN ADVANCE
EVO not charging fully and draining fast
Okay, here's my deal. My friend and I both have EVO's. We both are running Vaelpaks 3.1 rom. We both have the Battery Monitor Widget. When I charge my battery, it charges to 100% and 0mA. When my friend charges his phone, it reads 100% but the mA is not going to 0mA. Instaead it bounces between 64mA (red) or 252 mA (green). When he unplugs the phone, it drops 10% within minutes and continues to drop at a much faster rate than my phone.
Here's the kicker, when I pull his battery out of his phone and charge it in my phone, it charges to 100% and 0mA. then we put it back in his phone and it works great, until he charges it again. It charges the same way regardless of the rom we run. We have loaded Manilla Carbon by xxbabiboi228xx, VaelPak 3.1 and even stock and his phone won't charge to completion and drains quickly. Also, we are both rooted with Urevoked. We may switch to S on and see about switching the phone with Sprint unlees anyone has some sort of idea about whats going on with his phone. It may have something to do with the Hardware Version through settings/About Phone. My hardware version is 0003 and his is 0002. Thanks
you guys running the same kernel too?

It's the kernel, when your battery reaches 100% its supposed to stop charging but SBC kernels will continue to trickle charge. Li-ions aren't supposed to be trickle charged so they will wear out much quicker and possibly become unstable.

Battery Charging Issues

Normally I charge my phone nightly right before I go to bed and don't plug it in at all during the day usually.
I have noticed that on days where I have to use my phone heavily and require a charge midway through the day for the next week my phones battery life is almost cut in half. If I charge it regularly at night for a week or so the battery life will go back to normal. Has anyone else noticed this behavior? I'm trying to figure out if this is an incredible issue or an android issue.
Another thing I noticed is that under the battery stats it lists that my awake time is 43 hours. Its just slightly less that the up time. This makes me think that my phone isn't going to sleep. Anyone know how to tell if my phone is sleeping or tell me which app is keeping my phone from sleeping?
Install this app

Go to partial wake. in one of the drop downs.
I checked the partial wake usage and I don't see anything out of the ordinary.
I actually have an update to the situation. As a last resort I wiped my phone and loaded Cyanogen 6.1. At first it was working awesome. Battery life was awesome but as time went on the battery life got worse and worse and now i'm back where I started.
It sure seems like there is software problem with the way the phone tracks the battery usage/charging information. As I said it seems like charging the phone midway through the day or charging the phone before the phone is dead seems to have a negative effect on the battery. I don't get it. Letting the phone completely die isn't realistic. Charging the phone when I go to bed without affecting how long the phone last after the next charge should be totally doable you would think.
Does anyone have any suggestions or insight that might help me out.
You don't say if you charge with the phone powered off or on. But sound like you're always charging with the phone turned on.
I don't think the phone charges fully while turned on (to prevent overheating maybe? ).
If you can, I'd suggest trying to charge with the phone off, at least during the nightly charge.

Yes I do charge my phone while its powered on (like the rest of the world). I don't know anyone that turns their phone off to charge.
My phone is paid for by my company so that they can get ahold of me in the event of a server failure or some other IT related disaster. If the phone was off I wouldn't be able to receive those important calls.
I can't believe no one else has witnessed this type of activity with the incredible. I have tried 2 phones (replaced for an unrelated reason) and 3 batteries. The behavior seems like a software glitch. I have noticed with with both AOSP and Sense Roms.
Does anyone have an in depth understanding of how the battery system works on this phone. I also have an Iphone and the battery life compared to my android phone is ridiculous. I would use the Iphone exclusively but it doesn't do everything my android phone can do. I'm hoping there is a way to fix this.
Well, now you do know someone who charges with their phone off. Me!
I'm in IT as well and on call one week per month. But we don't run a third shift, so late night calls are almost never, and they have my land line number.
Back on topic, I have experienced better battery life while charging with the phone off. Maybe you can get an external charger until a solution is found.

Well i'm on call 24/7 and I don't have a landline.
What do you mean by "get an external charger until a solution is found." Do you mean a second charger to charge during the day? I have plenty of chargers. Thats part of the problem. Charging in the middle of the day I believe is causing the problem. Until a solution is found? Are you saying there is in fact a problem?
Having to leave my phone plugged in all day kind of defeats the purpose of having a wireless phone don't you think?
Please...anyone have any knowledge of how the charging system works in android and specifically how it might work differently on the incredible?

I should have said get an extra battery and a stand-alone charger that allows you to charge the extra battery while it's disconnected from the phone.
Have you read the thread in general titled 'your battery gauge is lying to you'. (or something like that). Good read. Also there's hundreds of other threads on the inc's battery issues. Well known problem.

If your up time and awake time are essentially the same, you definitely have something running in the background. Try menu/settings/applications/running services and see what program might be running that shouldn't be. You can also use an app called System Panel to do a comprehensive survey. I recently had an update that resulted in the program running continuously in the background, affecting my battery life.
Some other threads have discussed that after 40+ hours of up time, their phone goes into max CPU usage all the time. Again, using the app System Panel, I confirmed this for my own phone at 45 hours. My ROM is the stock Froyo 2.2 with a custom kernel. the simple solution is to power off/power on the phone which resets the uptime.
My routine is to charge the phone with power on over night so I can use the alarm. When I get up in the morning, I power off the phone and bump charge it for about 30 minutes until the light turns green again. Then I'm usually good for about 10 - 12 hours of uptime with 3-4 hours of awake time using a 1500 battery. That time can also be reduced considerably if I'm receiving a poor 3G signal.
I did originally have a problem with a program not allowing my phone to sleep but I have since uninstalled that program and now my wake time numbers are where they should be. I think the remaining battery issues are a result of me having to charge my phone in the middle of the day as a result of the misbehaving program prior to me uninstalling it.
It almost seems like the the battery in the incredible has a memory. On a hunch I have started completely discharging my phone completely everynight before I put it on the charger. As a result my battery life as almost doubled. When I get home at night I start playing angry birds with the brightness at full until the battery gets to about 3 percent left. This obviously isn't a permanent solution but It certainly sheds some light on the root of the problem.
Prior to doing the full discharge I did a bump charge and wiped my battery stats. The battery is working great now. I wish someone would create a kernal/rom that has this issue resolved. Since these new lithium batteries aren't supposed to have a memory anymore I'm thinking it has to be something that the OS is doing with the battery stats file.
According to this article you should fully charge and discharge once every 30 or so charging cycles to resync the battery meter with the actual battery voltage. So maybe the complete discharge fixed your problems.

not sure if this will help or not, but i have been running advanced task killer ever since 2.1(haven't gotten around to uninstalling before now, ha ha) and recently uninstalled it and installed watchdog task manager and my battery has increased two fold!
just my two cents worth.
