Battery Meter or Voltage Meter problem?

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.

Extended battery issues

Hello guys,
I have a GSM Galaxy Nexus running the latest Android 4.2.1 Officialy from Google. I hae bought an original extended battery for it, but the issue is that it seems that it holds less juice than the original one, that came with the phone.
With the default battery, i get around 3 hours of screen on and with the extended one, i barely get 2:40 minutes. Tried this a couple of times.
What's the matter with it ? Do i need to calibrate it somehow ?

I have the same battery and had the same issue. After using it for about a week it started working better. What I suggest is charge it all the way up and then use it until it completely goes dead then fully charge it again. Do this a few times then you should notice the difference which isn't huge but I'm averaging about 4-5 hours more than standard now.

I did this allready, and there's no improovement.
I have been using this batter for over 1 month now.

With Li-ion batteries, this should make no difference what so ever. It should get better over time. From what I've researched, you should never let a li-ion battery fully die. When it hits 20% - 30% fully charge and then don't charge again until you hit 20%. There are only so many charging cycles on a battery.
You might have something constantly running in the background that is eating your battery. Try juice defender, it drastically improved my stand by time.

What i was saying:
The stock battery holds a charge of ~3 hours of screen on time
The extended battery holds a charge that lasts less than 3 hours witch is strange because it haves a bigger capacity.
Is there any way to reset the baattery stats ? Or to reset the battery count ? Something like that ?

The whole "wipe battery stats" thing found in CWM is useless. Confirmed to be by a developer at google.

I see. Anything else i can try ?

Stock S3 Has poor and constantly changing Battery life

So, my phone's battery life is overall quite poor for the most part. some days it absolutely burns through my battery with little phone use, and other days it gets decent battery. i downloaded better battery stats, and for example. today my phone drained at about 10%/hour, but yesterday for example it drained at about 3%/hour. And today i did not even use my phone that much. Please help, as this is getting really annoying.
Here are some screenshots of my battery stats on two bad battery days

I know it looks like dolphin burned alot of battery, but that it just because it was practically the only application i opened and i used it for a couple minutes which i normally wouldn't do. then i few hours later, this was where my batter was at, and i swear i pretty much did not even touch my phone at all! http://imgur.com/NIfYnkl

Yeah I noticed something interesting as well. I have two batteries for my GS3, one is the stock battery that came with the phone and the other is a 4200 mAh battery from Hyperion Electronics. I decided to test each battery by charging each to 100% on different nights and not touching the phone overnight to see what my battery drain was
Night 1, I tested the stock battery and over night I went from 100% to 40% in a span of about 8 hours. That's a 60% decrease.
Night 2, I tested the Hyperion battery and over night I went from 100% to 98%. A total of 2% decrease in the same span of time.
Now yes I understand that the Hyperion battery is essentially 2x the battery capacity as stock, but just by simple ratios you'd think that since the stock was a 60% decrease that the Hyperion battery would be a 30% decrease, but it's not. The Hyperion battery is literally 1/30th of a drain than was the stock battery.
Something's wrong here and I wish someone could give a straight answer as to why these two batteries are demonstrating dramatically different results.

[Q] Plz Help!! Battery issue (fixed for now)

I bought G Pro day before yesterday. The device is amazing and i love it but i have got a small problem. First day i charged battery to 100% and i got a day usage with 25% of brightness set with screen on time for about a little less than 4 hours which is amazing. Yesterday i had to charge phone twice because the battery depleted within 2 hours on screen time and moderate usage like calls n text (no gaming). Today morning 80% power was left of second charge. I went to college and and did not use the phone much but battery got completely depleted within 1 hour of screen on time at 50% brightness. When i came home back i charged the phone to 100%, when i disconnected charger from phone the charge dropped immediately to 98%. After 3 mins it fell to 93% and now is depleting fast. there is no apps running in background or anything and no apps showing up in battery stats that may be depleting battery. Any solutions to this? can it be faulty battery? Plz Help!!!
Edited: viber or whatsapp was causing this battery drain. I rooted my phone n installed greenify. Hibernating all user apps fixed the battery drain. If anyone has battery drain issue may try this solution.

[Q] Extreme battery drain even with new battery and new charger on 4.4.4?

Basically as title reads. I've been having extreme battery drain. I thought it might have been my battery that was shot, so I bought a new one, as well as a charger. I even had a massive battery (don't know the mAh off the top of my head, and it isn't with me- but it was so large that it came with its own new backing) that also seemed to drain quickly. It seems the original battery would last 2-3 hours with barely any usage (a text or two; checking the time) and with regular usage (googling, reddit, texts) would be an hour. The large battery lasted 3-4 with barely any usage and 1-3 with usage. WiFi is off as well as GPS.. Only apps (besides what regularly runs) running are Handcent, Chrome, clock. That's all.
It also seems to discharge when charging and using my phone at the same time, so I have to leave it alone completely while it charges... And it charges really, really slowly. The large battery took 12 hours to fully charge last time I charged it. (I got a new one yesterday, seems my battery is still dying extremely quickly).
Here is what I am running on my phone.
Here is the new battery I ordered for it that I'm currently using.
I also use this to try to extend my battery life to a normal amount.
I am also waiting for this to come in the mail to help juice up my battery life to get through a day at work.
I bought a charger by RocketFish a while back at Best Buy which is what I used for a while before going to default S3 charger (brand new, I was originally using my S2 charger). Nothing seems to be helping.
So all in all, is my phone shot? Is there anything I can do to fix it? I'm not sure I want to go out and buy an S5 (especially with Samsung being so closed about bootloaders now). What can I do?
I'm using CM11 on 4.4.4

Well some people have complaints about Cyan's battery life so have you tried taking back to stock?
