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

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

thanks for the info, will give that wiki a read!
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.

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

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.

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
So,
I've flashed three or four ROMs over the last week (with a few different kernels) and they're ALL having the same issue:
I use the "miagi method" to fully charge the battery, but when the phone is ON, the blue LED comes on when the phone is still reading 83%. I turn it off, plug in, and after a few minutes it's at 100%. I've wiped stats, flashed ROMs and kernels and the problem persists.
I don't know if this is having an actual effect on battery life, but it sure is annoying.

I'm going to assume you've been to this forum?
Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.
If none of that helps you at all, my suggestion is this. I found the same thing for half the cost several months ago elsewhere if you look. It came with 2 batteries, one for me and my wife. The included batteries are notably not quite as good as the original samsungs. However, carrying an extra battery gives flexibility, and the wall charger does a faster and more effective job at charging any battery.
Plus, then you'll have a battery while you're other one charges!

Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.

++ on This .... I've used that calibration method (the 2nd one, off method) and it worked well for me.
hi i can solve this just follow simple steps
discharge your battery upto 17 percent
than use back camera with flash on take pictures with flash your phone will power off suddenly after 2 to 10 pictures.
just plug in charger issue is resolved your battery will be charged upto 100 percent
I've brought my Desire Z back for reparation (Mainboard died and replaced by an official repair center).
I've bringed it with my stock Battery fully loaded (I took it from the charger and 30 minutes later it died). When i picked it up, the battery was totally empty. Nothing in it. The Phone didn't even turned on!
It taked a while on the charger, but finally it turned on and was charged to 100% in normal time.
Since that, I experience a huge battery drain. When I release my phone from the charger on 7.30AM, it is dead on 4.30PM with no use! No SMS, phonecall, nothing. Only Gmail sync.
I've tried different ROM's (With- and without sense) and did restore my phone to stock. It doesn't solve my problem, the drain still stays huge, even with no apps installed!!!
I've tried another battery > same problem!
What can this be? Normally, my Desire Z last about 1,5 days oder 2 days when nothing happens. Why it's draining so fast, even if it's not used?
What can I do to resolve this ??

try a new battery? Reset battery stats and give it a few days to actually get accurate readings? 8 hours isn't unheard of especially if your battery is giving up the ghost. give those thigns a try and maybe turn off sync and/or data to see if that makes a differance.

Thanks! I've already tried a new battery, but that makes no sense.
I'm now draining it to zero, i.e. when it's fully dead, and then charge it to 100% for 8 hours. When it's charged, i'll wipe battery stats. Let's see.
When anybody has more tips, i'm pleased to hear them!
Here's a tip: don't drain your battery to zero. This is a great way to shorten the life of the battery, or completely ruin it.
For purposes of battery meter calibration, draining to 10-20% is plenty sufficient.
There should be no problem draining a battery to zero as shown by software. There is a myth/misunderstanding that this is a bad thing because people confuse it with the fact that Lithium Ion batteries can be permanently damaged if they are drained too low.
BUT any device using such batteries will have its circuitry setup to have 0% set to a point above this damaging threshold.
So the "too low" point in hardware is likely to be below the zero point that the phone's firmware and software will let you go to.

x2 I concur with this. No need to fully discharge the battery, one it probably doesn't even fully discharge because I'm pretty sure the software is saving you from yourself, plus when the battery stats are uncalibrated I'm fairly certain it reads as discharged but in fact is only partially thus the calibration is off. Lastly I'm if the opinion that throwing different charge levels works better because it more closely resembles real life charging situations. Also letting it charge for that long does nothing because the phone charges only a trickle when full in order to not ruin the battery, similar to a laptop. Overcharge protection....
Thanks again!
Now I did charge it to full and wiped Battery stats.
After 1hour 30 minutes, it lost 10%. Did only send 2 short mails with Gmail.
Here is the usage chart:
- Screen 54% (Time active 4m 51s), Brightness ~20%
- Mobile Stand-By 20% (Time active 1u 26m 13s)
- Phone inactive 18% (Time Active 1u 21m 21s)
- Gmail 5% (CPU Total 31s, CPU Foreground 25s, enabled 51s)
- Android OS 3% (CPU Total 21s)
CPU is on idle ~10%, as always. I don't see any apps that are burning my battery.
s there something abnormal here?
just compared it with my statistics (running virtuous affinity)...
Mobile Stand-By seems to be very high... i have 4% (time active 2 h 30 m)
maybe radio related?

This stats come from Virtuous Affinity also. I'd had never had any problems with such a drain with my 'old phone'. As soon as I got it back from the repair center, the battery drain is huge.
I've reflashed the latest radio for my phone, made a Superwipe and made a fresh install of Viruous Affinity. Let's see.
I think that 'Cell Standby' is killing my battery. It is at the top of the usage list with 38% and it's all time active. My phone was left it's charger at 7.15AM, now at 9.00AM it lost 20% of it's battery on idle use only. On 9.00AM, I've turned my phone on airplane mode. Let's see if that works.
I will recover the phone to stock tonight. If this isn't working, I'll return the phone to the store.
Even with the phone on airplane mode the battery is heavily draining. My last escape is to remove the SD Card. If the draining continues, then I will bring my phone back.
Does the battery came hot? Like more than normal?
With temp+cpu app you can monitor your temperature.
Because if on idle the temperature's around 25-28 C, you should be alright.
And then you can consider what steviewevie said; lithium battery can be damaged if you go on a too low voltage. Even if the phone as his ''protection'' to not get the battery to a critical level, the battery can loose power even if its not used.
Lithium ion, its cool but not perfect.
Try a OEM brand new battery.

I've seen plenty of people on XDA with this phone and others that have rendered their battery unable to charge by letting it discharge to zero. Yes, there are failsafes meant to prevent over-discharge, but they apparently do not always work. The damage is not "permanent" in that its just the protection circuit of the battery kicking in. But the only way to bring the battery back from "sleeping" is with a special battery meter with boost function, which most people do not have access to. So for all practical purposes, its cheaper to just buy a new battery.
http://batteryuniversity.com/learn/article/low_voltage_cut_off
Yes, over-discharge will not LIKELY kill your battery in this way. But there is no point in taking the risk. The battery meter is far from accurate in the best of conditions. So there is zero benefit to letting the battery drain to zero, as opposed to 10 or 20 %, just for the benefit of calibrating the battery meter.
Also, even if over-discharge does not instantly "kill" the battery, running full cycles at the least will shorten the overall life of the battery. Its best to avoid full cycles and charge often.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Now this is just my experience from reading the experiences of others on XDA. I know there are hardware techs that can give much more first hand experience with batteries and may disagree. But as I figure, better safe than sorry. Especially when you consider there is no real benefit to letting it drain to zero on purpose.

The temp of the battery don't exceed 28 degrees, I test this with Battery Indicator Pro. When discharged, the Voltage is around 3,6 (Which is normal behaviour). When charged, it,s 4,2V which is normal also.
I have already tried a new battery, and it doesn't make sense. Same behaviour.
I'm really clueless, because it drains the battery always. Airplane mode an removal of the SD card makes no difference.
I will return to stock tonight, charge again, and see if it behaves the same. When yes, then I will return the phone as I don't accept such behaviour (Normally, my Battery last 30+ Hours on idle).
Thanks for your tips and help for so far! I will report.
My G2 gets ghastly battery life. I've tried Juice Defender and I've recalibrated more times than I can remember. Most notifications are turned off and I'm conservative about powering off the various radios when I'm not using them. It wasn't always like that. I felt like I was getting most of a full day on one charge and loving it for many months, but something happened last summer I think. Maybe dust or moisture affected the phone. I've got a total of six batteries and three external battery chargers. No battery whether it's the OEM original, 1500mah spares that were amazing before, or the new 1800mah evo shift 4g batteries I tried out, will last more than about four hours from full charge to the 15% warning sound.
I've tried only charging in the phone. I've tried rotating batteries charged in the external chargers. Like I said, I've tried calibration scenarios of various kinds.
Last night, I took a fully charged 1800mah battery and put it in my phone and then charged the battery in the phone. The orange led never turns green when the phone is off. When the phone is on, I can just barely get the led to turn green at about 91% (starting from what should be a full charge that is reported as 80% by the phone). This takes a good 10 hours of charging. As soon as I woke the phone this morning, the battery meter started dropping while the phone was still plugged in. After unplugging, the meter drops to 80% in a matter of a few minutes.
Like I said, I tried juice defender. It only helps a little but the cost is waiting for the data radio to reconnect every time I wake the phone. I thought BT was the culprit for a while, but now it really doesn't matter if I leave it on or turn it off.
At the other end of the charge, the phone can run for several hours when the battery is supposedly between 1 and 3%. I know we are told to start charging again at 15% but my phone drops to that level in 3-4 hours of regular use. I haven't seen the phone report 100% charge on any battery in six months time, but it runs and runs at 1%. This is what bugs me. Is the phone just mis-reading how many milivolts are coming out of the battery? Why can't I complete the first step of calibration (charge overnight to the 100% mark)? Is there a hardware component that can be causing this or should it be entirely fixable in software?
Thanks for any ideas or tips

Yes I have many times but thanks for the suggestion.
Figured so.. Too bad, would have been too easy. I'm starting to see some batttery drain on my desire z now too. Im wondering if mine is a radio issue.

I changed radios and did RIL matching last fall based on other's comments about better battery life, 4G and GPS. While I've had faster GPS locks and maybe better 4G performance, my battery life did not improve. It may have even gotten worse.
Today I'm trying out some different CPU governor settings. The CM 7.2 RC1 default is 'interactive' and I wouldn't normally touch those settings. I think the powersave governor helped a lot, but the phone became almost unresponsive. Trying 'conservative' now. I should have read This long ago, but just got around to it today. I might invest in the SetCPU app as well.
OK, I can count on a good six hours of normal use if setCPU is holding down the max cpu frequency at night or when the screen is off. I'm still tweaking. Today, the phone crashed while playing music over A2DP and tracking a run with runkeeper. I think it needs to tick faster than 368Mhz when the screen is off.
Are you seeing improvement? I changed radios and like you havent seen much improvement. But I am a little better off than you are. My battery drain is terrible (1-3%per minute) only when connected to the internet (4g or wifi) or using navigation. If the screen is off, or if Im using non-internet apps I seem to get regular battery use. Good luck with your cpu settings.. I have ordered a new battery, but I doubt it will solve my issue. I may try tweaking my settings too soon, but Id better research more.
Just wondering do you have SuperCharger V6 installed? On my Desire Z I had some serious battery problems just as you mentioned. After I would flash my ROM (wiping the caches + reinstalling) my battery life would return to normal. But whenever I would flash SuperCharger v6 my battery life would spiral out of control. My suggestion for a ROM that handles battery life fairly well is Andromadus Audacity B2, just make sure you download and flash GAPPs (google apps). For example running that rom I have been getting very good battery life, approx. 16-20 hours of battery life with moderate use) with default CPU settings and data always turned on. I'm sure if you use Juice Defender to control your data you'll get above average battery life.
Note: Andromadus is an ICS (android 4.0) ROM

Thanks (and thanked) Ive been waiting till ICS roms are bug free and having working cameras, but I think I may just jump on it now. My battery issues are untenable at the moment on a CM7 based rom. Thanks for the advice.
I was seeing some improvement due to SetCPU profiles. However, now if I have GPS and Bluetooth on so that I can listen to music and track my run in runkeeper, the phone seems to 'crash' after about 35 minutes or so. The battery meter shows that the battery takes a nose dive and I think the phone shuts down at 1%. If I restart the phone, it might say I have 30 or 40% charge left but then it drops rapidly again. It seems like it hates the warmth of my pocket. If I let the phone out in the cool air like on my desk, I can reboot at get back to 60 or 70% even though it was just saying 3%. I'm not running SuperCharger.
I'm trying to find cheap G2s for parts on ebay now. Maybe I can at least test out my six batteries in a different phone to see if any of them are shot. They all seem to have the same problems in my phone.
This will be my final update. I bought a used G2 off ebay. The same batteries I used before now show as fully charged when I expect them to be fully charged. I will be getting a feel for general battery life over the next few days, but I expect battery life to be roughly the same. I just won't have to guess at what the current battery level really is.
I'm seeing now that the new phone will show a 60% charge when the old phone shows 15% for the same battery at about the same time.
The new phone shows 100% when topped off but if I put the topped off battery in my old phone, I see 75-80% charge.
I may try sending the old phone to HTC depending on what they offer for repair services.

I think what's happened to your old phone (and mine!) is that the onboard voltmeter chip is reading low. I've compared the on-board mV reading to a multimeter-measured battery voltage and what the phone reads as 3.9V the multimeter gets 4.2V (a fully charged Li-Ion battery).
Who knows what's behind it, but it seems like a hardware problem to me.
