Hi all,
I am puzzled by my problem. I am using Virtuous 2.7 + King's BFS kernel #4.
My phone battery will drop quickly from 100% to 92% right after unplugged from the power cord. By quickly, I meant I did not use the phone, killed all tasks, and battery will drop to 92% literally in minutes.
Bump charging, wiping battery stats, wiping dalvik cache, killing all tasks are not helping at all. I don't have SetCPU, but someone in the forum mentioned they have SetCPU, and it is not helping either.
Is anyone having this problem? Does anyone have any idea on how to solve this?
Please help.
Thank you!!!

I spoke to RMK as well as others about this in IRC, doesn't look like anything we can do, deep in the HTC code I guess.
I have the same issue using SkyRaider 3.1. Battery is 100% then after 5-10 minutes drops down to low 90s. It bothered me at first but after several days of moderate to heavy use and still having almost 50% battery left at the end of the day, I just figured it was some kind of bug when reading the battery level at the beginning. How is your battery life overall? If it's like mine, then i wouldn't worry too much about it as long as it's lasting longer. I'm using the 1750mAh battery from Sedio.
I was having the exact same problems until I went back to stock everything and bump charged. Took the OTA for 2.2, rooted, custom recovery, bump charged, wiped stats and cache and now I'm good to go. I usually dont think crap like this works but it made a huge difference in battery life and stopped the 100-90% problems I was having.

I found this on EVO forum, but I don't know how his solution works. I personally don't think this would be the solution.
http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=704272
I am using the 1500 mAh battery.
My battery life is uptime around 24 hours and awake time around 6-9 hours depending on usage.
so you're not having the issue anymore, after going back to stock (non rooted) with the official OTA 2.2?

KB Smoka, so you don't have this problem anymore?
Do you think format the phone and wipe all the data will help?
Have anyone tried formating the phone?
I've searched and found that the cause is the phone saying the battery is charged fully when its not basically so to fix this after it goes to 100% while the phone is one then u should turn it off and let it charge fully from there

I did bump charge this phone, but it still drops like crazy.
I'll try this out tonight.
Thanks!
Is this a once time fix thing or do you have to do it every time you charge?
bump charging 4 or 5 times in a row (basically bump as many times as you need to to get it to where the light turns green withing a minute of 2 or plugging it in again) and then wiping battery stats solved this for me... kinda.. i still have to bump twice, but after that it'll stay at 100 for a good while and work it's way down normally, no jumping 10% down..

That is bump charging. Something htc is unable or unwilling to fix.
The issue has been known for a while and you have to 'bump charge' every time to avoid the 5-10% drop.
Here's their response about fixing the "bump charge".
"Dear **********,
I understand you would like to know if an update has be released to help get a full charge on your battery without having to bump charge it.

Do you bump charge every single time you charge right now? It's pain in the butt if I have to bump charge everyday.
Yup every day. 4 or 5 times is way overkill though. Just charge phone until green, turn off (don't need to unplug), wait until it turns green then do the plug/unplug one more time.

Went to stock (official OTA), rooted, custom recovery, bump charged, reset stats and cache and I'm good now.
I charged it to "full" while it was powered on. Once the light turned green I turned the phone off, charged again until the light turned green. Took about 25 minutes. Powered up in recovery wiped battery and cache and now I'm good. The key is after doing all this you have to let the phone completely die.
If you're wiping your battery stats after a bump charge, you will have this problem every time you don't bump charge.
If you wipe your battery stats after it goes green without a bump charge, you won't have this problem.
This is because the software thinks the bump charged battery levels equal 100% charge. A bump charge adds approximately 10 percent of charge.
Formatting your phone or any software changes won't actually do anything other than wipe your battery stats while your phone is not at bump charge levels.

The reason this happens is because the battery gets charged fully to 100%, and then is allowed to slowly drain back to 90% (or so) before it's charged back to 100% again. This is how Lithium batteries are charged.
Try this: charge the battery to 100%, and immediately disconnect it after it's full. Notice how the battery doesn't drop to the low 90's immediately.
The reason "bump charging" appears to work is because there is no drain on the battery, since the phone is off. It goes to 100% and stops.
There's nothing we can do code-wise to fix this; it's just how the battery technology works. Keeping it fully charged at 100% while on would damage the charging capacity of our phones.
Btw.. wrong forum.
Solutions in search of a problem
Let me preface this by saying that I’m not an electrical engineer, or any sort of expert on phone hardware, but I think a couple issues are being confused. I’ve seen many posts about this battery “problem” here and elsewhere and an important point is being missed. People are confusing what the battery is actually doing with what the phone SAYS the battery is doing. They are NOT the same thing. The battery is a physical device and it will do what it’s going to do.
Battery life is a function of battery quality, initial state of charge, and demand. If you want the battery to last longer, look at ways of reducing demand. What applications are in use? How long is the screen on? What brightness level? Overclocking and undervolting settings? All these will affect ACTUAL battery life.
At lot of the “solutions” discussed have nothing to do with conserving energy use, but have everything to do with messing with how the phone REPORTS the state of charge. A good example is the issue of the initial drop reported by many users during the first few minutes after unplugging the charger. I see this on my own phone. If the phone is “taught” that 100% charge is when it is totally crammed with juice and plugged in as well, it’s not surprising that there is a good bit of voltage drop (+/- 10%?) right after unplugging. Does this mean there is a problem? NO! It’s just the battery doing what batteries do. A lot of the suggestions about wiping battery stats and such have nothing to do with saving energy. They are ways of fiddling with how the phone REPORTS its condition under various circumstances.
My advice: if you are happy with how your battery lasts, over the course of a day or so, then learn to relax, crack open a cold brew, and revel in just what a great phone the Incredible is. If your battery isn’t lasting as long as you need it to, then look at ways to save power or get a larger capacity battery. Tweaking the battery meter function is simply a feel-good exercise and won’t get you any actual improved performance. END OF RANT.
I can confirm that my gf's phone and my good buddies phone(both were never rooted) have never had a problem with the phone charging up slow first off(both phones charge about 1% per minute). And since they accepted the OTA, have not had the problem of charging to 100% and quickly jumping down to 90%. For instance, the other day my buddy charged his phone while on to 100%, played a game for about 2 minutes and closed it, battery was at 99%. Now I have tried and continually try every possible solution to my battery dying quick and charging slow, but am realizing that this must just be the cost of customizing my phone to my liking. And at least for the moment, a stock 2.2 DINC is just not an option for me.

Sorry that I posted in the wrong forum. I thought this is related to the kernel or ROM I am using (Which is development right????).
Not to question your knowledge about the "battery technology", but why is it only happening to certain people? Nowadays most device are using Li-ion battery, why this phenomenon do not occur to all devices?
Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.
I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats
Is there an advantage to calibrating a battery if it is not being charged in the phone?
This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?
I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager
in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0
I re-flashed my ROM last night (Runny Extreme Surprise.) Before this, I had no issues what so ever.
Now my battery seems to refuse to charge past 35%. After flashing the ROM and setting up a few minor apps, I drained the battery to 0%, charged the phone while off via AC (not USB) for about 5 hours and it still didn't get to the green light to say it's fully charged. I booted it up to see where it's at and it's at 35% and now seems to refuse to charge any further.
I tried this again, also deleting the battstats file (Just to be absolutelyyy sure) and got the same result.
Interestingly enough (i'm not sure if it's relevant), the phone says its current battery voltage is 4179mV, which is around the same it usually reports when it's been fully charged at 100% in the past.
Does anyone have any idea what may be going on here?
Go into recovery and check what percentage you have there. If it reports 100%, download the rom again and reflash.

No idea. Perhaps the battery is failing? How old is it?
You can also try a few troubleshooting steps. Test another battery in your cell, different charger and so on.
Edit: test with a different stable GB rom for good measure. I doubt it's that but you never know.

I am used to having my phone charge to 100% over night, and then when I unplug it it goes immediately to 99% This morning I had the blue LED notification to let me know I had a full charge. But when i took it off it said 60%, my first impression was whoa thats not right.
tbh im only running stock FF13 not even rooted.
Where is that 40% difference coming from?
thnx

maybe bad battery. is it bulged?
I dont think so, its a extended life battery. I was more looking to see if anybody else had an issue similar.
for the past week i've been having battery issues where the charging LED lights up, but the phone does NOT charge. or the phone says charging, then the light turns blue saying 100% but as soon as i remove the plug, the % drops to whatever the battery truely is at.
even when I go into about phone>battery, the time spent charging does not show that it has been charging. Also better battery stats does not seem to even show any processes being run...as if theres no battery stats to read from. also Gsam battery wont even calculate the average time left
my usb port works fine. i've used all different usb cables/chargers. i've wiped battery stats numerous times. ive done clean installs of ics and even tried going back to gb roms. issue reappears on BOTH oem batteries i have.
That's just one of those pesky ICS bugs that affects some phones and not others. I ran one Epic on the official ICS update for 4days and went back to gb before any bugs occurred, so I guess I was lucky not to have any aftereffects. It may clear with a custom Rom , you need to research the threads.
Good luck.

I have an epic that was working fine. I got a new phone so it sat with the battery dead for a little over a month. Now I gave the epic to my daughter and the battery is all wonky. It will charge up to 100%, but when I take it off the charger it will last anywhere from 20 minutes to 4 hours, which I got the other day with no use and airplane mode on. Now here's the wonky part. It only goes down to around 88% and than goes dead. If I plug it back in it says it has about 80% charge. But if I don't plug it in and just try to turn it back on it acts like it doesn't have enough juice. Now on this phone I'm on cwm 6.8.x or something like that and you can't wipe battery stats so I didn't try that. So I guess my next step would be to flash another recovery and wipe battery stats. I did just flash the peoples ROM 2.2 (I think was the number) just yesterday and wiped everything else for a clean install. Has anyone heard of or experienced this? How can I fix this? Will wiping battery stats work? Also, the battery was great, I could easily get all day out of it with average use just a month ago. Please and thank you.
Nothing?
This community is very small now since this device is old. You need to have patience regarding replies to threads.
Sounds like you need to replace the battery. Look on Amazon and eBay.
I haven't heard of this happening before, nor has it happened to me. Even though some would advise against it, i'd 'calibrate' the battery just to see if that would fix it. If that doesn't fix it, I have no idea.

From what I recall there was a lot of different opinions about the battery wipe in CWM.
If you google it there should be a video that shows you how to use it. I think you drain the battery until phone shuts off then charge it full, unplug it wait 10 minutes, charge it full, then turn it on and wipe battery stats. Then run phone dead again and charge again. Don't really want to charge it until after running it dead.
I used it a couple of times and it seemed to help but people say it has no affect because the battery stats are in the rom or something like that.
I also have heard that after you load a new rom you have to give it some time and the battery will get better.
I have never experienced what you are so sorry I can't help.
I would guess most would say its the battery buy a new one cause it sounds like the battery is only charging 20%.
I still have my stock battery after almost 2 years. It will get me through the day if I just make phone calls and text, but I have to keep a charger handy if I'm going to use the phone for other things. Sometimes my battery will drop if I reboot. It will be at like 30% and when I reboot it will come on with 15% and tell me to charge it.
They say the 1800ma model will work in this phone and I would check into that if buying a new battery.
Well good luck!
The battery was working fine two months ago. That's why its weird to me. Wiping the stats didn't help. I guess a new battery is in order. Grrrrrrrr

If it was the original battery it already has some miles on it and if it sat for a month or two dead in the phone then it's most likely toast. You will get best results with li-ion batteries during the first 300 to 500 charges, so after a year or two the battery will naturally loose it's ability to hold a charge, that's just the nature of the beast. A new battery will do wonders!
The percentage that is displayed is usually directly correlated with battery voltage. So 3.200 V would represent 100% and I think it is 2.6 is 0%. So what sounds like is happening is the battery has a bad cell and jumps from say 3V or whatever is 80% right to some voltage below 2.6. A new battery "should" fix this.

check that 4g isn't on or google talk isn't on. Google now is a big battery waster too. For unexplicable drains, check for a defective battery and if all else fails a clean wipe/install. I've had just about all of these issues on the 4 epic's we own.
