Please, please, please. SBC kernel for Synergy?
I am tired of my 3500 battery running out after 18 hours, I was getting 60 hours from Warm 2.2 RLS5.

SBC wont give you better battery usage, just an extra 10% when you wake up. I highly doubt your 18 will turn into 60 just because of SBC alone.

Warm 2.2 was a great rom.that rom gave me the best battery life I have ever had except for my current setup...I am on wifi once I got home but 8 fairly rough hours on 3g. The wake time shows I used it.
I did get better life w froyo though. I could get 40+ hours pretty regularly and half would be 3g. If I stayed on wifi I am sure I could get 60+ currently.
Lithid, with all due respect, but I am on Synergy. When I charge my phone until the green light comes on, i unplug it and it drops from 100% to 80% in about an hour.
So I tested some things out. I ran battery clear dead and recharged, phone on, and then when the light turned green, I rebooted it and when it booted back up, battery monitor widget said I was at 79%.
Ran dead again about 12 hours. Recharged, phone off, until light turned green and turned on phone. BMW said 78%.
I am not very smart, but both times it took 2 hours exactly to recharge until light turned green. That is telling me that the phone has a timer, or shuts down charge at a certain voltage. It also tells me that it takes the same amount of time to charge my 3500 battery as my old stock 1500???. I call BS!
With SBC, it took 3 hours to fully charge my 1500, and almost 6 to charge my 3500. So what you stated above, makes no freaking sense to my stupid arse. Please re explain to me again how I was not getting 3 days of use before and only about 17 hours today with screen on time of 3 hours today....

I don't know what you guys are doing to get such terrible battery life. I get 19-20 hours with moderate use out of the stock 1500 battery.

So this morning, I unplugged at 9am from charger. I turned off everything that makes an EVO an EVO, like Background data, and sync so that it does not update any fb or email or anything without me doing it. I have had WiFi on since then and I have it set in Spare Parts to never while plugged so it will shut down when the screen is off. I also turned off Mobile network always on. so I now have a NON EVO, EVO. And at 5 hours, I have 71% battery left. That will get me to to about 17 hours of drain time. so far today I have 2 hours online with it. The 17 hours is purely estimate as I may go 5 hours later without picking it up. so I may be more like 24 hours on this charge cycle.
That is no where near what I was getting with SBC and RLS5 of 2.2. With Synergy, I am not expecting the same run time as before, but with SBC, I would definately be getting WAY MORE life out of battery. 2 days at least.
All I am saying is the the EVO without SBC, DOES NOT fully charge my 3500mA battery. PERIOD!

I agree 100%. I wont use any sense 3.0. Gb rom until an SBC kernal is available. I myself wouldn't use it but my gf would. I'm a cm7 person and only use SBC cause I need every drop of battery life possible. Without SBC I get that initial drain and I wont sacrifice that. For me its safe and a must have and people can disagree with me all they want on the validity of SBC but I believe in it and won't change my mind. If I ever get time I might throw my hand in to creating a kernal but right now I'm working on my apps new release

Nothing wrong with SBC and s reputable replacement battery. Mine is a Seidio and I used SBC for 4 months on 2.2. No problems! Well except only charging every 3 days unlike everyday now.

update from Today on battery life. I am not at 13h 48min since unplug and BMW says I have 12% remaining and estimates that dead time is 1h05min.
Display time on is 78% and in time that is 5h 48 min.
Wifi on 9h, 8min. I had to make a trip to the grocery store and pharmacy. Dont know where the other 2 hours of time went that it should have been on, cause I did not turn it off.
Phone idle, 7h 55min
I would consider this a normal day. Only about 10 min of talk time. I got similar to this with Stock ROM and a 2600mA battery from Sprint.
If your battery is registering fully charged at 78%, then you must've wiped battery stats without a full charge or something. Charge it fully & then wipe battery stats. Let it drain completely, then charge it fully again. You should get better battery life after doing so.
I've seen in some people's wiping/flashing directions to wipe battery stats (or everything except the SD card), and that's incorrect. Don't wipe battery stats unless your battery is fully charged. Wiping at less than a full charge, or not following through with the conditioning directions, can mess with your battery life.

No, I did not wipe battery stats. How would I get fully charged if the phone will not let it fully charge??? That is my complaibt in the first place. It is NOT charging my 3500 battery anywhere near full charge.

I was not talking about when your phone is fully charged. I'm saying your battery will still drop the same at 100% or 90% you said at 100% you can get 60 hours. But at 90% your only getting 18 hours or whatever... I was saying, doing that math it doesn't make sense. I also use the 3500 battery. No sbc and I charge to 100% not 78%

Gotta disagree with lithid here as well. If you watch the amps separate from the charging indicator, they keep going at max after the charge hits 100% and don't stop until it gets fully charged. For me the full charge without SBC is about 70% of the actual battery capacity
Lithid, I just ask that if you were to unplug your phone when your led turns green. Then do a full restart, BATTERY MONITOR WIDGET will show you your exact capacity charge and it will not be 100%.

I also want to add....
Lithid, I totally appreciate your interest and I hope I have not offended you or my posts read like I dont care what you say. I try to be respectful, but sonetimes typing out things come across wrong to the reader. You have done some fantastic work for the EVO and I think you are first class for doing it.
You have also caused me to research things so I can learn what you are talking about so I dont come off as an idiot.
The only thing that is troubling me is that I freakin love Synergy. It drains my battery very quickly compared to 2.2. My hunch was that the stock kernel was the culprit. I tried golden monkey and freedom, same problem. I tried chop suey today. I am at 10%, so it is about the same as others. CSuey is a bunch quicker than the others for performance.
So I guess what it comes down to is this; I would just like to try an SBC kernel for Synergy just a. Couple of charge cycles to see if i still get the same endgame. If I still only get 18 to 24 hours of battery charge, I will be a non SBC guy forever. But no one is doing one, so I can not test it. Solution???
And again, Lithid, thanks for your time on this and keep up the good work! I appreciate it!

Stock 1500 running synergy godmode. Moderate use checking email placed about 15 calls. Checked xda on the hour. Downloaded apps. Browsed the web and listened to music for a few hours. I think your battery might be going bad. Also if you have a taskkiller you need to get rid of it. I let Android do its thing and have had zero battery problems. I easily get a full day and then some out of my EVO.

Small update. All these nay sayers about SBC got me thinking, and the one above that said my battery may be going bad, so I am now back in Myns 2.2 RLS5 and SBC#15 kernel. My old setup. I am going to charge my battery FULLY tonight, and in the morning, I am going to see how long my battery lasts on that setup. I was getting 2.5 to 3 days with moderate use.
Then, when it gets dead, I am going to Recharge it fully and then immediately flash Synergy and then see how long of life I get with a SBC charged kernel and the reflash and see if I get more than 18 hours.
If nothing changes, then I will forever shut up about SBC. If I get significantly longer life, then I will pay someone to do an SBC kernel. Fair enough??
Plugged the phone in to charge at 1:05am today. Light turned green after 3 hrs 15 min. It is still not fully charged and that is at 9 hours 15 minutes. It is almost there. Right now it is showing 22mA charging and dropping. Goal is 0, which means full charge using SBC. I do realize that SBC also charges the battery at a slower rate, but that in itself cannot explain how the phone said the battery was FULLY charged after 3 hours.
So as soon as it gets to 0, I will reboot into recovery, wipe batt stats, then reboot into 2.2 RLS5 and unplug. Then I will run completely down until phone ****s off, then recharge once again using the SBC kernel, once fully charged, I will reboot into recovery, restore my Nandroid of Synergy RLS1 and see how long batt lasts on SBC charge. Then when I run that completely dead, recharge using Stock kernel from synergy and see what happens.
Screw SBC, I'd be happy with HDMw1n, 2-way call recording, and standard speed enhancements ALL in one, stable kernel. We don't have that yet.

I just recently bought a 3500mAh extended battery from amazon. (http://www.amazon.com/gp/product/B0042TY68C/ref=ox_sc_act_title_1?ie=UTF8&m=A1N1UQZS4G6GV9). I just got done fully charging it, i let it charge fully over night, just unplugged it and boom 10 minutes unplugged with me not even touching it just letting it sit on my desk we are down to 95%. I know you are suppost to cycle these batteries and stuff before u can actually see the fully life of it and i plan to do that. My question is i downloaded battery monitor widget and on the main screen its calling the battery a techno-Li-ion 1425/1500mAh battery. I know this isnt right ive cleared battery stats probably 10 times total now, through recovery and through the battery monitor widget app. Im hopping i didnt get ripped off and it just takes a few discharges for the phone to recognize the new battery? Any help would be appreciated.
I plan on letting the battery get to 15-20% and then charge it all the way up again and do these a few times, as well as clear the battery stats. This is what i read to do with new batteries? Please correct me if im wrong..
When using an extended battery you are not going to get a full charge unless you condition it or you could use a SBC kernel.
how much will u get out of it then without the sbc?
I bought this exact same battery. I used it at the time on my Evo unrooted. The first one that came to me (2 weeks late) wouldn't even power up. The second one they sent me I ran for about 3 weeks and put the stock battery back in. I was about to get 9 to 12 hours on my stock battery and with this extended I was getting the same. 2 weeks into using it the battery life got crappier everyday. To me it wasn't worth the added bulk for the same or less life. Since then I now run CM7 on the Tiamat sbc kernel with my stock battery that is almost a year old and get close to 18-20 hours out of an almost year old stock battery.
I use the SBC kernel, battery monitor widget, and the 3500mah battery. The thing lasts for days. Literally. When the green light comes on at "100%", that means NOTHING.
I ran it stone cold dead yesterday on purpose. Plugged it in at 10:00pm using my 800mah AC charger.
10:00pm: Plugged in, begins charging at ~700mah (max for my charger)
12:45am: Phone indicates 100% @ 4018mV but keeps charging at 700mah
2:00am: Charge rate ramping down @ 4197Mv
2:45am: Charge rate 100mah
3:00am: Charge rate 50mah
4:00am: Charge rate 15mah
4:30am: Charge rate 10mah which it remains at when fully charged (4198mV)
Stone cold dead to green light was only about 3 hours. BUT, stone cold dead to actually fully charged was really double that.
Obviously if the battery isn't dea, it will take conciderably less time. If you charge it with a PC, limiting the total current to 500mah, it will take conciderably longer.
So battery monitor widget calling it a 1500mAh battery doesn't mean anything? Right?

Yea I'm at 8hr40min as of right now @ 17% battery. I've had my display backlight turned down and have been at work the whole day doin nothing with my phone but light texting and posting in this thread. With my stock battery I get around 12 hours before the phone almost dies with regular/mild use.I'm starting to think this battery was a rip off.. hopefully once I charge it back up it will last longer but idk... If anyone has any tips or tricks to make this battery last longer please help me out.

The newest version allows you to override that. Previously, the phone was telling it the capacity was 1500mah because that what the normal battery is supposed to be. The new version let me change it to 3500. So the % estimation should be accurate now. It is claiming I have 70% remaining or 2450mah. And 70% of 3500 is 2450. Now, where it came up with 2450, I have no idea.
The first time after ur charged the battery when u got it did u let it completely die or plug it in when it hit 10% or so?

My first full charge on the same battery I got the exact same behavior. I was on the Stock Kernal that came with CM7.
Second charge, after changing to the Tiamat SBC, my battery is screaming... 6+ hours of heavy usage (video, web, lots and lots of text and 30mins of calling) and I am still over 50%. By now, I would have had to charge the regular battery...
Very pleased with this thing...
well im about ready to unplug mine for the day and see how it goes, i fully charged it with the phone off with a wall charger. And have been cycling it witht he phone off by unplugging it when the light turns green, waiting for the light to turn off, then plugging it back in until the light turns from orange to green again. Ive been doing this for the last hour or so because somone in another thread about this battery said it help him out alot, i did unplug it when i first woke up and it dropped from 100 to 92 within 3 minutes so thats when i tried this cycling, i did unplug it in the middle after doing a dozen or more of these cycles and it staid at 100 for quiet a while then dropped to 99 after about 5-6 minutes of being unplugged and me browsing the web and market this being a huge improvement so id have to say the cycling of the battery does help idk how or why but whatever im not complaining ill post back later tonight once i see how the battery acts.
So far I've had terrible luck with this battery can't get more time than stock. Charging it with an SBC kernal and it doesn't help, was avoiding spending 60 bucks on a battery but I think Ive no other choice.

im at 2 hours with it right now, down to 70% i used it pretty heavily about 30min ago to reflash cm7, savagedzen sbc kernal, download all my apps, setup launcher pro plus, and re confiugre everything. It dropped rather quickly from 100 to where its at now so i guess we will see, BMW is estimating 10hr40min remaining battery life right now which would put it at about where my stock battery would die at around 12-13 hours, so we will see :-\
*edit*
BMW now saying 12hr10min at 70% battery? weirddd...
*edit*
BMW now saying 16hr23min at 65% battery, ive been using it moderately, used 4G for a second and WiFi for a few minutes as well...
Here's why the drop...the Evo along with other phones use bump charging to charge the battery meaning when the light is green you have anywhere between
90 and 100 percent at 89 percent down to zero you should not see such a dramatic drop...its a Evo thing the large drop

go into bmw, go to settings, monitoring preferences, second from the bottom battery capacity, just change that value from 1500 to 3500, took me a while to find it as well.
all of the sudden every kernel I use drops from 100% to 94% within just a few minutes even after being charged extra. I was using net's 4.3.4 sbc no havs for awhile and sbc didn't seem to work. went back to sbc #15 and sbc worked for awhile then it just seemed to stop. then decided to use 4.3.4 no sbc no havs and less havs. Already setting at 89% since unpluged 30 mins ago. suggestions??
Probably damaged battery. Look on Amazon you can get a stock OEM Evo battery for under $10.
Sent from yo moms house
didn't damage your battery, you have to recalibrate it. there are a million ways, charge to full, go into recovery, wipe battery stats, then drain it so it won't even turn on and you will be fine.
FYI, my evo never charged to 100% from the day I got it. Non sbc kernels turn off the charger early because of the mV spike.
When you charge w/out an SBC kernel, the charger stops at 100% and doesn't start again until it reaches 90% but it still says 100%. If you're not using SBC, expect a drop of some sort when taking it off the charger until you get to 90%.

To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.
this is a copy/paste from another post as well
I used to get all weird at the initial drop too, but the actual life of the battery isn't affected
all you're doing is describing the normal behavior that prompted the SBC kernels to be developed....lol

You have to give Kernels some time to adapt to your phone... you can't try it for a day and say OH THIS DOESN'T WORK IT SUCKS
I bought a 3500mah extended battery about a week ago. When I got it, I turned off the evo, inserted the extended battery, and charged the device while powered off for approximately 8 hours. I did this for the first few days. Each subsequent charge, I plug the phone in, power it on, and leave it plugged in for approximately 8-9 hours with the Savaged Zen 2.2.1 SBC CFS kernel.
During this period, I was able to get about 12-14 hours of battery under heavy, almost constant usage. With light usage (texts/twitter/trillian) I was able to pull about 40 hours.
In the last few days however, my battery life has halved. It is still better than the stock battery, but not by much. I am able to pull in around 6 hours of heavy/constant usage before the battery dies. Has anyone experienced this? I've looked at all the tips and tricks and don't see anything that specifically addresses how to charge the bigger battery. I was under the impression that 8 hours with an SBC kernel would fill the battery completely.
Should I be charging the battery with the phone off?
PS: I have tried wiping the battery stats and that has not seemed to help.
I personally use http://electronics.pickegg.com/Elec...-for-T7373-Touch-Pro2-6341706512982200005.JPG
It's SOOO MUCH BETTER on the battery! Plus there's never a chance you'll pull it off the charger before it is finished. Just swap between your normal battery and the 3500 back and fourth for the best results. But everyone knows that our phones won't charge the batteries correctly.
A simple search for t7373 battery charger will take you to places to buy this at. DO NOT OVERPAY FOR IT! I got mine in a 20 buck package. got 2 batteries, this thing, 2 screen covers, case, and so on. 3 clear cases. lol bunch of stuff. on ebay.

try reconditioning the battery, charge until full(green light) the unplug and after light goes out plug it in again, repete until you get the orange charging light then let it charge fully(green charged lite). see if that helps

but all that's doing is overcharging it. The average person doesn't have that much time to waste. lol plus the only way it works is if you do it on a daily basis. However, the funny thing is HTC/Sprint actually posted that as an official fix. HAHAHA! It's really just a trick to get the not so smart people to do it and shut up. lol! It's not conditioning it. wait until battery is almost empty then swap battery and let it charge outside of phone. then put back in. ;-)
edit. just remembered. wasn't people having issues fully charging these 3500s? I'm almost sure they were. yeah. the only way to charge them fully is actually outside the unit! I COMPLETELY forgot about that! Did HTC ever fix that issue? I could be wrong. so need an expert in here to give a second opinion. thanks lol

so you think its better to carry and swap out batteries and reboot everytime plus buy an extra charger. no thanks, i'll do the not for smart people every once in awhile.
edit: dont know havent heard about any issues not fully charging 3500, or if it is better to use stand alone battery charger
charge it however you like.. I see no difference in results no matter how you do it.. the results in life completely depends on use and how much stuff you have on.. Getting in the habit of turning data off and sync, bluetooth, gps etc is the best way to extend battery life. Charging it full is full.. It doesn't make any sense whatsoever to "recondition" it.. when you fill something up.. how does it get "more full" than full.. logic tells you it's complete bs.. unless you want to believe it then I'm not here to convince you of what is and isn't.. Use the system settings toggles to turn your stuff off.. data and sync are the biggest killers.. You'll still get calls and messages.. just turn it on when you actually want to use your browser.. sittin in your pocket is just wasting precious battery..
Thanks for the input. I'm going to hold off on buying a charger and attempt to charge it as suggested in a couple of these posts. If that doesn't work, I'll invest in the external charger and report back.
GreenTea, any updates on this? I just bought the 3500 and an external charger (why not for $5 a piece). I'm wondering if there's any issues charging inside the phone and whether or not I need to wipe batt stats.
I know this is an old issue, but maybe I can add some input:
I have a Seidio 3500mAh battery I use for my Evo 4G (used it in the my HTC Hero first, then in my Evo 4G). I can get roughly four to five days with little use out of the battery (I'm using CM7.1 right now)...until I turn on 4G.
Once I turn on 4G, I may get eight to ten hours out of it with light use.
What you may want to do is keep the 4G radio off until you need it...this hopefully will improve battery performance.

I bought a 3500mah extended battery about a week ago. When I got it, I turned off the evo, inserted the extended battery, and charged the device while powered off for approximately 8 hours. I did this for the first few days. Each subsequent charge, I plug the phone in, power it on, and leave it plugged in for approximately 8-9 hours with the Savaged Zen 2.2.1 SBC CFS kernel.
During this period, I was able to get about 12-14 hours of battery under heavy, almost constant usage. With light usage (texts/twitter/trillian) I was able to pull about 40 hours.
In the last few days however, my battery life has halved. It is still better than the stock battery, but not by much. I am able to pull in around 6 hours of heavy/constant usage before the battery dies. Has anyone experienced this? I've looked at all the tips and tricks and don't see anything that specifically addresses how to charge the bigger battery. I was under the impression that 8 hours with an SBC kernel would fill the battery completely.
Should I be charging the battery with the phone off?
PS: I have tried wiping the battery stats and that has not seemed to help.

You need to download BATTERY MONITOR WIDGET. Put the widget on your home screen. Monitor voltage while charging. Full is 4200mV. Anything less is not full. Recently, i can not get it past 4180mV. Sometimes, I charge overnight with phone off, then plug into my car charger going to work with phone on to try and top it off.
Calibration nor conditioning will fix the issue. It is the kernels and they just are not right yet for gingerbread.

With moderate to heavy use I'll be able to pull in 12-15 hours on a full charge with my 3500 mah non-seido battery. Light usage will net me about 40-48 hours. SBC seems to give a couple more hours if the phone is plugged in and turned on during charging. I live in an area without 4G, so I cannot respond to 4G battery use. I've heard it is a battery killer though.
I currently run MIUI on my Evo, and I'm having a problem. My phone will say its fully charged and all, with the green LED saying so, but when I unplug the phone, my battery level drops down to 94% immediatly. What is this? I bought a brand new battery and I still got this problem. Anyone who can I can do?

You either need to calibrate your battery (app off the market). Or try using a SBC kernel, which properly charges your battery to its full capacity. Make sure its an aosp kernel like mason, or taimat.
Lol sane experience on morning
wanam v10.6 siyah v3.0.1
Definitely needs calibration.Just search for how to properly do it on the forums.I personally use battery calibration from the app store.Charge the battery to 100%,then use the app.Unplug through phone and use the phone all the way until it dies on its on.Then plug it in without turning it on and wait until its fully charged.Turn on and use it once more until it dies.Charge again to 100% then after that you should be good to go.Hope this helps ya.

A non-sbc kernel will charge to 100%, then begin to discharge to about 90%, then cycle back up... Depending when you pull the plug, in reality it could be anywhere inbetween that range, so 100 is not a true 100... Calibrating the battery by deleting the bin file doesn't produce any long term results..
A manual way to mimic a full charge would be to charge to 100 percent, unplug, plug back in for a bit and repeat about 10 times, and it should give you a decent charge.
That's a manual way of doing what a SBC kernel does automatically for you
Hey,
Like they said get the SBC, and calibrate your battery, and that should fix it.
I assume at night you are plugging it in till the morning, and this is your issue because in the middle of your sleep it is reaching full and stopping its charge. so by the time you unplug it drops down to how much it discharged.
Charging with your phone off solves this to
Let your phone completely drain till it turns off. Charge the phone while its off till you see the green "charged" light. Unplug usb, wait for green light to disappear and plug usb back in, phone will still charge. Repeat process about ten times. On the tenth time boot into recovery and wipe batt stats, then reboot phone.

Flashed the SBC, and properly calibrated my battery. I'm still at 100% battery level after an hour!

Good to see that worked for ya. I'd +1 the SBC kernel if you hadn't found that it has been working for you. I've been using Mason's 14 with ICS for a few weeks now and i've found that with the screen off, the battery sits at 100% for quite a while. I haven't used the battery calibrator and maybe i should see how that helps. Does it show significant results or is it mostly a gimmick?

Im not sure what everyone on here thinks it does, but calibrating the battery is strictly for stats. It will not lengthen the battery life or keep it from draining down from 100% faster. All it will do is assure that your battery stats, aka estimated time you have left on your battery, are more accurate.

good luck. I tried sbc and it was working well for about two weeks, then my battery suddenly started draining super fast. Rumor has it that SBC will in time ruin your battery, which it seemed to possibly be doing to mine. Got rid of SBC, flashed back to build28, ran vipermod script and undervolted -75mV and im magically back to normal.
My findings are that if I just run the stock kernel with build 28, I get the best battery life. As soon as I started trying mason kernel, tiamat kernel, or even faux kernel on build 31, my battery drained too fast for my liking. Thus far I have reached 40 hours on my battery on build 28, with vipermod, stock kernel!
I just got brand new batteries, i have not calibrated nor wiped battery stats after flashing. I do have Mason's kernel and am under-volted by -50. I also have an app called battery xl it helps control what is running when you may not be aware or forget. My battery stays at 100% for over 2hours with minimal use. The only thing i heard is that you have to use the battery down to 10% and then charge while phone is off.Do this about 4 to 5 times and that conditions it(when it's brand new) and it will help your battery last longer before needing a replacement.
Just my .02
Several people have reported bad experiences with the SBC kernels, but there are many more (myself included) that have had absolutely no issues with them and I have used several iterations of the SBC since it was first released for the Evo.
At this point, for me, the benefits more than outweigh the risks. If you do have a problem, buy a new battery. They are pretty darn cheap these days.
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
Did you wipe battery stats?

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.
