So I got one of those CHEAP 3500 eBay batteries from China with the bulky back cover w/o the camera lens hole plastic. You've probably seen them, they are under $10 shipped...
I'm not sure if:
A) I have a dud battery
B) Falsely labeled 3500 battery
C) My less than ideal/proper battery training did any good
D) Battery is not properly "talking" to phone - ie temp/mV/Percent
E) BatteryCalibration App is confusing the eris/ROMs
My issues with the replacement battery include:
1 - Battery life is barely any better. It feels more like a 1750 or smaller replacement. Even though the battery is THICKER than stock
2 - Max charge I can get with BatteryCalibration app for 100% is around 4200mv. 0% is around 3400mv (I don't remember the exact number). REALLY? A dead battery equals around 3400mV?
Note: I had 9% battery life today and had only about 300 less mV than my wifes phone with a stock battery. Here phone had like 88%. (Sorry I didn't jot down the exact numbers).
Note2: Currently:
Wife Phone: 57% 3809mV (Note to self - check when 100%).
My Phone: 78% 3951mV
Wife Phone: 2.1 XtraSense 5.0.1
My Phone: 2.3.7 Condemned CM7 V19 Vanilla
My Phone was replaced by Verizon a few months ago and her's is still from when when bought them new.
Any thoughts on what I need to do different (other than get some more concrete numbers to paste)?? Is my battery a Dud or falsely labeled? Other?
Try this:
- fully charge the phone, so that you get a green LED. (Not absolutely necessary, but I think will be better than doing the rest while not fully charged.)
- still plugged in, restart the phone in Recovery.
- Wipe menu, wipe battery stats
- Restart phone and unplug.
See if that gives you better battery life.
(By the way, FYI, it's xtrSENSE, not xtraSENSE. Common error.)

I thought that is what the app does... but I'll give it a try when charged.
Another thing to try is once your phone is charged. Before going into recovery, power the phone off. You'll probably notice the led go orange. Leave it plugged in until it turns green. I've even unplugged it and plugged it back in a couple of times until green every time before booting into recovery and wiping stats. Just another option to try. I've actually seen mine change to green while powered on and indicate a full charge then go to orange when I turn it off and go another 20 minutes or so before it turns green to indicate a full charge.
I'm trying doogald and CondemnedSoul's suggestions.
ATM I'm still on my 1st draining since this morning.
The problem/concern I have is the phone seems to thing the battery is still a stock 1300 battery. (Even the Battery Monitor Widget app lists the battery as 1300).
Additionally, the battery temp never varies more than 0.2 degrees per phone apps.
I'm wondering if the CHEAP battery is not properly communicating with the phone. If not, is there anything I can do other than buying the seido battery instead?
Here's an app screenshot.

So, I'm not sure if anyone has this problem. I pull my phone off the charger in the morning when I wake up, and it's immediately at 96%. Is this a defect with my phone, or is it something I can fix?
Thanks
It's normal. It's actually better on the battery this way. There were some debates about the EVO and kernels that performed SBC charging.
This has been covered in another thread but here it is again...
HTC has used a new charging method on the e3d so it will charge to 100% then stop charging until it hits 95% at which point it will start charging again.

i use the battery monitoring widget.. it has a log that shows you the actual % of the battery while charging.. sometimes the phone will be displaying 100% while charging but in the logs you can see the battery is decreasing and not at 100%.
which is why when you pull it off the battery drops right away.
I'm glad I decided to search first, otherwise I would have the whole XDA community after me wanting to kill me.
Anyways, I have one of those notification icons that show me the battery percentage, but it NEVER reaches 100%. I am constantly checking it to see if I have reached 100% and nothing. Even when I leave it plugged it all night, it only gets to 99%.
I have also tried *#*#4636#*#* and it also shows 99%. Is this normal?
Your battery will technically never be at 100%. As even the most minute drain places it at 99%. Doubtful that HTC is that precise, I understand your frustration
Ok, but my evo 4g WOULD show 100%. That's why I was confused/worried when my 3D showed only 99% max.
This is a frustrating quirk with these phones. I also use battery monitor widget (love it BTW) and its pretty clear how the phone acts around a full charge. See below, graph of battery percentage overnight sitting on the charger.

If i happen to pull the phone off the charger when it is actually full (or as close to as it will get) then it seems like the battery really lasts much longer throughout the remainder of the day. If i pull it at say a 95% mark then it seems to be down to 80-85% by the time im out the door in the morning after a few emails / dickin around. If i pull it when its full then i only seem to lose a few percent, maybe up to as much as 5% by the time im out the door....
SBC kernel fix / help remedy any of these behaviors?
"Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Don't panic, it's all as it should be. Don't try to outsmart your smartphone.
Recently they found that charging to a little less than 4.2V you get more charge/discharge cycles out of your battery.

Ok, here is my problem.
The battery indicator its stuck either at 100 % or 95%. I know my real batery life with a program (battery indicator pro).
It seems that the only way to charge it correctly is power it down and plug it to the charger (original by the way). If i charge it while is turned on, the indicator that signal the 100% charge never pops up.
I'm using the go launcher ex, its not rooted, and the stock rom (2.2.2 International).
PS:Yeah i know, my english is pretty bad, so please bear with me.
Mine gets stuck at 80%, both charging and discharging. After 3 or 4 hours at 80% it will go to 100% a few hours later. Hopefully they'll fix this on an update! The battery itself seems to be operating properly.
Well... I guess I take comfort in knowing that I am not the only one experiencing this odd bug. I have the exact behavior and like it's been said, my 5.0 player seems to have normal battery life. I just can't trust the charge indicator.
The method this device uses to estimate state of charge is VERY primitive.
It has a fixed table based purely on battery voltage - the problem is that battery voltage can vary quite a lot for a given state of charge depending on load.

I'm not sure why they didn't use the MAX17040 fuel gauge that is built into the MAX8998 PMIC...
mV readings seem more accurate than %:

mV readings are a poor estimate of state of charge, since they'll go up when on a charger, and down when under heavy load.
Our battery % indicator is derived directly from those mV readings. (Which is why our battery % estimate sucks.)
What IS odd is that you seem to have a case where the charger held flat at around 4060 mV for a while - which does correspond to an 80% reading. I think I've seen that once too, might be a kernel bug there, I need to look.
Showing 100% with the voltage dropping shouldn't have happened - I've never seen it myself.
I believe the "stuck" numbers are 80%, 100% and sometimes 65%. Happens every cycle for me, 80% being worst. But on a reboot, immediately drops 25-35% (depending how long it was stuck for). So if you reboot every hour, it will show good readings (but I reboot about once a month).
My tablets battery will say 100 then how down to 3% so ill turn it off then back on and it'll say like 35%. Then most recently its been stuck on 35-37% for some odd reason.
Did you guys try wiping the battery stats in CWM?
So I took out my sd card this morning and realized I had been using my replacement battery not the original one that came with the phone. (They are both the same official samsung battery, I just marked them so I know which is which) Later on this evening my phone was at about 45% and I decided to switch batteries because I had opened it back up to reinsert my sd card. I start the phone back up and my 2nd battery, which I always keep at 100% as a backup, was showing only 81%...
I thought this was odd since I put it on the charger for about a half hour every few days to make sure it's fully charged before I start the day just in case I need it. Anyway, I forgot about that quickly and set my phone down on my desk. About 5 minutes later I get a text message, unlock the phone, and low and behold the battery says 83% (and no it was not plugged in all day and had not been charging!) Has anybody ever seen a phone "charge" while it's not plugged in before? It went up to 93% and then finally started to die. Slowly increasing every ~10 minutes give or take. I even have the screenshots to prove it was "charging" while not plugged in.

The only time I've seen a battery increase it's charge is when the temperature of the battery changes rapidly.
And perhaps if a cell bridges over ..
But that's usually reserved for lead acid type batteries....not lithium ion cells..
You have taught me today ....as this is a first for me ....
And I wouldn't be surprised if the battery is starting to fail ...so watch it to prevent any possible device damage.....g
Um. No. What you're seeing here is recalibration as the phone adapts to the other battery.
So you changed batteries while plugged in ??
Ah yeh, that explains the battery charge increase, as the new battery takes over, and the cycle record was not reset because the phone still has power...
battery is fine......my bad....g
I've had that happen before, and I only use OEM batteries with my phones. Like somebody else said its just a software hiccup where it's recalibrating. I've had times where I've pulled a battery to flash something at like 50 percent battery, when I boot back up I have like 10 percent showing, and it will slowly increase back up to like 40 percent. Its happened a few times and there's nothing to worry about.

No the phone was not plugged in. And I've switched batteries before without this happening. I know its not a problem I've just never ever watched a phone "charge" itself

Sounds like a battery stats "hiccup" to me, when you rebooted after swapping the batteries it thought that the battery was the same, so it just kept polling like normal and reporting the "new" status. But i think that when a battery is inserted like that, I don't think that it can instantly report what the exact new voltage/Mah so it pretend charges like what you reported. AT least that's the most logical thing i can think of. My extended battery would "charge" like that sometimes if I battery pulled for some reason...

Hey guys, I know these threads aren't exactly welcome, but this was kind of weird.
I was carrying out my papers, listening to my Spotify playlist. After about three hours, I had 34% battery charge left. About ten minutes later, 11%. Then my phone died, because the charge was gone and it didn't get past the boot logo.
I arrived home about 10 to 15 minutes ago and tried to boot my phone, it booted and had 24% charge - how does that work?
Here's a screenshot

Internal resistance of the battery increased due to high temperature, voltage dropped to shut off threshold. After the phone was allowed to cool the resistance dropped and voltage returned to the actual 24% level remaining.
It sounds like your battery could do with replacing.

Sounds reasonable, but I don't think so. I was doing my paper round at ~1 degrees C and my phone was in my front pocket of my jacket, so it was pretty cold. (Now thinking of that, maybe I should have written that in the OP, as well.)
But I think you're right with the battery exchange. Ever since I got my replacement S III I've been having better and yet again worse battery charge-durations. It lasted longer, but took from ~10PM charging through my XBox 'till 2PM when I go out and stuff...
But still, thanks
My S3 (2nd phone) battery lasted ages when I first got it but now a few weeks later it seems the battery just doesn't last as long as it did when brand new. I'm simply going to replace the battery with a new 1 every 3 months

There are several possible causes to your issue
- When batteries are cold, their capacity drops so when you get home it warms up and has some charge left
- Your battery's electronics had an incorrect counter. Do a full load/unload cycle and it should calibrate correctly

I don't think it would be a faulty counter. The phone was so dead it didn't reach the boot logo.
I'd say option one is most likely.

Although I've had this phone for over a year now, it took me up until now to bring this up:
When charging, once the battery level reaches 90%, it shoots up to 100% although the battery isn't fully charged. Using Cool Tool to read the battery voltage from /sys/class/power_supply/battery/batt_vol_now shows that while idle, the voltage reaches the full capacity of 4.3 volts. However, when the phone does any sort of processing or heavy I/O, it drops to something lower, which is expected since it clearly hasn't reached full charge.
The phone acts as if the battery is fully charged, so when I unplug it, the battery level (and voltage) instantly drops to somewhere between 90 and 100% depending on how long I leave it plugged in after it first shows 100%. I don't take this as a sign of battery aging, since if I leave the charger plugged in for an hour after it charges to 100%, the battery voltage stays at maximum capacity and drains normally depending on how much I use the phone.
What I'd like to know is if this happens to anyone else, because to me it seems more like a software issue rather than something hardware-related. I am running stock 4.4.2, rooted. There are no system-level modifications due to HTC's system partition protection, which I haven't found a need to bypass.
