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?

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.

Weird battery charging issue (stuck at 83% in all ROMs)

So,
I've flashed three or four ROMs over the last week (with a few different kernels) and they're ALL having the same issue:
I use the "miagi method" to fully charge the battery, but when the phone is ON, the blue LED comes on when the phone is still reading 83%. I turn it off, plug in, and after a few minutes it's at 100%. I've wiped stats, flashed ROMs and kernels and the problem persists.
I don't know if this is having an actual effect on battery life, but it sure is annoying.

I'm going to assume you've been to this forum?
Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.
If none of that helps you at all, my suggestion is this. I found the same thing for half the cost several months ago elsewhere if you look. It came with 2 batteries, one for me and my wife. The included batteries are notably not quite as good as the original samsungs. However, carrying an extra battery gives flexibility, and the wall charger does a faster and more effective job at charging any battery.
Plus, then you'll have a battery while you're other one charges!

++ on This .... I've used that calibration method (the 2nd one, off method) and it worked well for me.

hi i can solve this just follow simple steps
discharge your battery upto 17 percent
than use back camera with flash on take pictures with flash your phone will power off suddenly after 2 to 10 pictures.
just plug in charger issue is resolved your battery will be charged upto 100 percent

Do you have a 3500mah battery? What is the best way you have found to charge it?

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.

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.

[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..
