Quick Battery Drop in Initial 10%

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.

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 **********,

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?

Battery Charging Issues

Normally I charge my phone nightly right before I go to bed and don't plug it in at all during the day usually.
I have noticed that on days where I have to use my phone heavily and require a charge midway through the day for the next week my phones battery life is almost cut in half. If I charge it regularly at night for a week or so the battery life will go back to normal. Has anyone else noticed this behavior? I'm trying to figure out if this is an incredible issue or an android issue.
Another thing I noticed is that under the battery stats it lists that my awake time is 43 hours. Its just slightly less that the up time. This makes me think that my phone isn't going to sleep. Anyone know how to tell if my phone is sleeping or tell me which app is keeping my phone from sleeping?

Install this app
http://www.appbrain.com/app/spare-parts/com.androidapps.spare_parts
Go to partial wake. in one of the drop downs.

I checked the partial wake usage and I don't see anything out of the ordinary.
I actually have an update to the situation. As a last resort I wiped my phone and loaded Cyanogen 6.1. At first it was working awesome. Battery life was awesome but as time went on the battery life got worse and worse and now i'm back where I started.
It sure seems like there is software problem with the way the phone tracks the battery usage/charging information. As I said it seems like charging the phone midway through the day or charging the phone before the phone is dead seems to have a negative effect on the battery. I don't get it. Letting the phone completely die isn't realistic. Charging the phone when I go to bed without affecting how long the phone last after the next charge should be totally doable you would think.
Does anyone have any suggestions or insight that might help me out.

You don't say if you charge with the phone powered off or on. But sound like you're always charging with the phone turned on.
I don't think the phone charges fully while turned on (to prevent overheating maybe? ).
If you can, I'd suggest trying to charge with the phone off, at least during the nightly charge.

Yes I do charge my phone while its powered on (like the rest of the world). I don't know anyone that turns their phone off to charge.
My phone is paid for by my company so that they can get ahold of me in the event of a server failure or some other IT related disaster. If the phone was off I wouldn't be able to receive those important calls.
I can't believe no one else has witnessed this type of activity with the incredible. I have tried 2 phones (replaced for an unrelated reason) and 3 batteries. The behavior seems like a software glitch. I have noticed with with both AOSP and Sense Roms.
Does anyone have an in depth understanding of how the battery system works on this phone. I also have an Iphone and the battery life compared to my android phone is ridiculous. I would use the Iphone exclusively but it doesn't do everything my android phone can do. I'm hoping there is a way to fix this.

Well, now you do know someone who charges with their phone off. Me!
I'm in IT as well and on call one week per month. But we don't run a third shift, so late night calls are almost never, and they have my land line number.
Back on topic, I have experienced better battery life while charging with the phone off. Maybe you can get an external charger until a solution is found.

Well i'm on call 24/7 and I don't have a landline.
What do you mean by "get an external charger until a solution is found." Do you mean a second charger to charge during the day? I have plenty of chargers. Thats part of the problem. Charging in the middle of the day I believe is causing the problem. Until a solution is found? Are you saying there is in fact a problem?
Having to leave my phone plugged in all day kind of defeats the purpose of having a wireless phone don't you think?
Please...anyone have any knowledge of how the charging system works in android and specifically how it might work differently on the incredible?

I should have said get an extra battery and a stand-alone charger that allows you to charge the extra battery while it's disconnected from the phone.
Have you read the thread in general titled 'your battery gauge is lying to you'. (or something like that). Good read. Also there's hundreds of other threads on the inc's battery issues. Well known problem.

If your up time and awake time are essentially the same, you definitely have something running in the background. Try menu/settings/applications/running services and see what program might be running that shouldn't be. You can also use an app called System Panel to do a comprehensive survey. I recently had an update that resulted in the program running continuously in the background, affecting my battery life.
Some other threads have discussed that after 40+ hours of up time, their phone goes into max CPU usage all the time. Again, using the app System Panel, I confirmed this for my own phone at 45 hours. My ROM is the stock Froyo 2.2 with a custom kernel. the simple solution is to power off/power on the phone which resets the uptime.
My routine is to charge the phone with power on over night so I can use the alarm. When I get up in the morning, I power off the phone and bump charge it for about 30 minutes until the light turns green again. Then I'm usually good for about 10 - 12 hours of uptime with 3-4 hours of awake time using a 1500 battery. That time can also be reduced considerably if I'm receiving a poor 3G signal.

I did originally have a problem with a program not allowing my phone to sleep but I have since uninstalled that program and now my wake time numbers are where they should be. I think the remaining battery issues are a result of me having to charge my phone in the middle of the day as a result of the misbehaving program prior to me uninstalling it.
It almost seems like the the battery in the incredible has a memory. On a hunch I have started completely discharging my phone completely everynight before I put it on the charger. As a result my battery life as almost doubled. When I get home at night I start playing angry birds with the brightness at full until the battery gets to about 3 percent left. This obviously isn't a permanent solution but It certainly sheds some light on the root of the problem.
Prior to doing the full discharge I did a bump charge and wiped my battery stats. The battery is working great now. I wish someone would create a kernal/rom that has this issue resolved. Since these new lithium batteries aren't supposed to have a memory anymore I'm thinking it has to be something that the OS is doing with the battery stats file.

According to this article you should fully charge and discharge once every 30 or so charging cycles to resync the battery meter with the actual battery voltage. So maybe the complete discharge fixed your problems.

not sure if this will help or not, but i have been running advanced task killer ever since 2.1(haven't gotten around to uninstalling before now, ha ha) and recently uninstalled it and installed watchdog task manager and my battery has increased two fold!
just my two cents worth.

[Q] Why is my battery losing life, or not displaying correct percentage?

About a month ago, I flashed Gingerbread onto my Epic 4G. Did nothing else, been running the usual BatteryLife by CurveFish without any hiccups or fluctuating readings.
However, recently, I don't seem to be getting a full charge. Or, the battery likes to drain. Either that or BatteryLife is not giving proper readouts anymore. For example, I can plug my phone in and let it charge. Its LED will go blue and the widget shows 100%. But, now, sometimes I'll look at the phone again later (while it's still connected with the charging cord or not) and the widget will read something like 82%. And, just now the widget is now showing 78%.
My battery has been fully discharged and recharged many times before for proper calibration. I even ran a battery calibration app. Still, this problem happens. What exactly is going on? I have had the phone tethered to remain charged and never once had a problem with the battery. I do know when I flashed Gingerbread, my battery life has increased dramatically.

Charge till you get the fully charge notification
Then turn off
Then go into click work recovery
Go to advanced
Click reset battery stats or something like that
Put back on charger
This proly happens cause of overheats from the super crap **** gb leaks
Also discharging the battery doesn't help
Sent from my SPH-D700 using XDA Premium App

Then, why does everyone say to get the most out of your battery, you discharge it fully then charge it up to 100% about a couple times to maintain proper battery life and calibration?

There is an issue with some installations of the gb leaks where the battery stops charging at 100% even when it is still plugged in. I had this issue and could not remedy it. Went back to a solid ec05 base and my charging works fine again.

Bad battery, wake issue or usb port/cable?

So after some time I've been battling with my battery life through the day. Few months back it was great, Id easily get a day no problem! Then I found I had a wakelock issue and had that fixed.
I now suddenly have almost multiple things going on at once but first a small back story.
Went to bed one night and had it plugged into the wall. Went to bed at 60% and woke up and my phone was down to 6%. I thought, well the usb port is bad or the cable. Took it into the sprint store, they of course say "it looks like its charging just fine, the light is coming on" (the light was on during the night too).
They checked the battery and they said it was bad. Im wanting to take it to another store and have them check, because either: they didnt want to replace me with a new phone or replace the usb port if thats bad.
1) Bad battery- in a matter of 30minutes (during my lunch break at work) my battery dropped from 63% to 14%- only used 3g for facebook and sent 2 text messages. And my phone is undervolted and underclocked
2) Possible bad usb port- I plug my phone in all day at work, and 90% of the time the screen is off. The % of the battery doesnt increase, but maybe decreases slightly (I have data and everything turned off while at work because I get no data signal).
3) wakelock- so suddenly I'm getting a huge percentage of system usage of 54% in my battery stats. A few months back it was maybe 1%? I flashed the .img that sets the wimax, PRI, NV, etc to what fixed the issue back then. Im just confused how this has come back now when I havent even updated anything related only my rom (MIUI 1.8.26).
So I've ordered 2 2000mah batteries off ebay- I wasnt going to pay $40 from a battery story across from the sprint store (as they didnt have any stock, only extended batteries).
If anyone has had a similar experience, or would know what is the culprit would love to get feedback. Hopefully I can get this fixed soon. Maybe just a trial and error.

Something really strange just happened. I checked my phone just now and the battery is at 98% and just maybe 30minutes earlier it shut off because of low battery
What I explained before about using my phone on my lunch break was only 2 hours ago and showed 16%.
I always wipe my battery states when I update my ROM or install a new kernal.

Don't wipe battery stats if you don't have a full battery, it'll keep your battery from charging fully.
It may be the battery, but since you're getting new batteries you'll know then. If you didn't get an external charger, I'd suggest doing so. That way you can guarantee that your extended batteries get a full charge, and you can switch out a dead battery with a fully charged one if you keep having problems. The usb port on the Evo is crappy anyway, but if the light comes on and stays on & you can transfer data through the usb port then I doubt that's the problem.
It could be hardware failure, but wait until you get a new battery and have properly calibrated to come to that conclusion.
In the meantime download Battery Monitor Widget, that should show you your true battery capacity even if the system will not. You don't have to use the widget, you can just open the app. Once you see that your battery is fully charged, calibrate your battery properly. Wipe battery stats at 100%, let it drain until it shuts off, charge to 100% without breaks, and you should be good to go.
Good luck!

Thanks for that!
I just bought a battery from BB to hold me over (50$ for a 1750mah battery?! )
when it charges to 100%, should I go into recovery, or use battery calibrator (app)?
Ill install that battery monitor too

BMW has the feature to wipe stats. I also recomend to look at the reports and judge when the battery is full by looking at mV. 4200mV is full charge. Then wipe stats FIRST, then unplug and run down completely, then recharge fully with out unplugging.

Ya just noticed BMW had that feature. Forgot I had a menu button. LOL!
This battery I got at BB is a "1750mah".
You know what I realized what might be the issue? Back a few weeks ago, I bought an extended battery to use to take videos at a concert. At that point I wiped the battery stats at 100% of the 2500mah or so battery..

[Q] battery dies too soon

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

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.
