Has anyone else noticed this. I will be using my phone and toward the end of the day it has about 40% left. It has that much since I usually leave the data network off unless I need it. I reboot it and it now says it is very low on battery I lose basically 35%. Any help appreciated other than don't turn off/reboot my phone until it is time to charge it overnight.
It's an extremely well known issue, that (so far) has no solution.
Does it happen with the other vesion of the syindicate rom non full?
Happened to me when I would reboot with the stock rom.
I just assumed it takes a lot of power to turn on and off.
Been an issue for me since day one. Hell it just happened to me awhile ago. I rebooted the phone with 46 percent battery than once rebooted showed 6 percent. Kinda gotten used to it but like stated above its an issue that apparently has no solution. Especially when flashing something through clockwork, it really drains the battery fast. Been an issue for me since 2.1 and all roms I have tried. Pretty sure its a hardware thing.

Have not tried yet but does it happen if you shutdown then power back on instead of using reboot option
Sent from my SPH-D700 using XDA App
rebooting the phone is not going to use upwards of 30% of your battery, nor would flashing a ROM. If that were the case, your phone would heat up to ridiculous levels and your battery would probably explode with that kind of output
The problem is most likely coming from miscalculation of the true battery level (which has been well documented in other threads on xda), which is rechecked during the boot process, and corrected. I've noticed that if my phone has gone long periods of time without a reboot, that this behavior happens. If you reboot your phone once every few days, it rarely happens, and if so, it's not nearly as drastic of a drop.

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.
What does it mean if, after resetting your phone, the battery level drops from 60% to 13%? Is that hardware? Is that the ROM? is that the battery?
I ask because, after hanging on a PRL update (that i don't think was successful) for an hour, the phone wouldn't stop pulling down data for any discernible reason, so I reset it. Before the reset, the SRF 1.2 baterry icon showed 60% battery and after booting back up, the phone prompted me to charge it because it was down to 13%. In addition, I put the phone on the charger for the PRL update, during which the charge level actually decreased slightly and the phone heat up to around 35C. Spare Parts reports the battery is healthy. Is this just a freak occurance or should I be worried?
Don't worry. Just run the battery calabation procedures. Theres several ways to do it floating around the threads. Also, i've had prl updates hang as well just check under phone status in settings if it changed. Even when it has hung on me it properly updated and showed whatever I was changing to.

this happens to me a lot...i have calibrated a few times and it always happens...it usually happens after i dip below 70 percent in battery life..when i reboot, it can say 8 % or worse.and sometimes gets stuck at at a specific battery for a while and reboot sometimes brings it back to the normal battery level..i mentioned this before in a thread but I haven't found a solution...so i barely reboot my phone unless i need to backup in clockwork or flash something
Oh man. I reboot my phone once a day to flush the RAM and keep the system fresh.
I rebooted in CWM to reset the battery stats, btw, and when I hit the "reboot phone" command, it rebooted into CWM 3.0.2.5 (I'm running the latest 3.1.0.1), which was jarring. Before that, after leaving it on charger for less than an hour, it jumped back up to about 57% and charged to full in another hour or so. Unfortunately, the batt. reported a full charge at 93%. I bump charged it up to 94%, but I ultimately decided to reset the stats just the same.
Are these known symptoms of something, or just hiccups?
I have had this issue as well. I believe it to be a calibration issue. I swap three different batteries so I attribute it to the different ones.
Strange thing happened the other day, my phone was at 22% or so and then all of a sudden just shut off. I switched batteries and it was fine, but strange.
I'm beginning to wonder if my battery is borked for my phone. I've done every single thing out there to ensure my battery was always 100% charged and calibrated.
However, today my phone read as being 100%. Went home, charged it up when the phone was powered off to make sure it actually did get to 100%. It did that, all was fine, or so I thought. A bit later, I check my phone and it's reading 72%.
There is no way this is normal for a battery. My phone has been dropped a couple times (mild drops, not huge ones), so wondering if it's possible a cell in the battery has been borked?
Had it been calibrated?

I said it in my first post.
What ROM? Did you look at it when you removed the charger? Did it still say 100%? Was it warm when you picked it up? Did you have signal? Did you install any new apps? Did you just reboot? Did you have a random reboot?
Don't sweat it, charge it and check it again.
No ROM, just a regular Gingerbread shoved through Odin, along with CWM purple.
The phone was 100% before I put it on the charger. I only checked the phone when I heard it doing the signal lost/found noise, and that's when I saw it went down dramatically (there is NO way that attempting to find a signal can lose battery power by 28% in 30 minutes).
Phone was not warm at all.
I have about 2 bars of signal.
I have not installed any new apps.
I did not reboot.
I never have random reboots (it's a reason why I don't mess with the Gingerbread ROMs).
I'm not sweating this, I'm more annoyed. And, all people do is say "Charge it, do this and that to calibrate, turn off phone, charge it again, reset battery stats, spin it 360 degrees, read it a bed time story...." But it simply doesn't fix it some times.
Wouldn't this point towards a faulty cell in the battery?

Look at your percentage when you pull it off charge. There is a bug in the Gingerbread leaks that kills the bump charging. So while it says 100% while connected, at that time it continues to run at 100 Mhz but not charging actually killing your battery. So you can go back to EC05 stock and see if it still does it to be sure. Assuming you did reset the battery stats already with that bed time story...LOL.
I see Spare Parts has a "battery condition" category. Can anyone verify its accuracy?
I was at about 49% battery life when I rebooted my phone (to try my new Maxroam sim card) and when I started my phone again I was down to 22%?!
I have attached a screenshot to show this? Anyone have any ideas what the problem is? Is this normal. My ROM & Kernel is in my Signature.
I've had the opposite happen, too. Had 40% battery left, rebooted, suddenly it had 60%.
I'm 99% sure it's not an actual change in battery charge. It's probably something related to how it measures battery capacity, and rebooting throws it off. I wouldn't worry too much about it.
This has happened on my Captivate as well as my GNex when it randomly reboots. I have noticed that it usually corrects itself over maybe a 15-20 minute time period. I have no battery charts to prove, but when my captivate would crash and reboot the battery would be much lower than it was before like you described. If you watch, you'll see the percentage go back up without charging. Its just a glitch in the reading when things crash or don't shutdown correctly.

Hey guys, so for the past few weeks my G3 has been rebooting randomly, at first it was just once or twice a day. But now it's at the point that I can't use my phone anymore, it's CONSTANTLY rebooting. People suggested a battery issue, so I've changed my battery but the issue came back a week later. These reboots started around the time I flashed a thermal mod provided on XDA forums but I've flashed back to stock countless times, I've performed hard resets, factory resets and changing my charger but nothing seems to work.
I've also noticed a new issue today, my phone will show 54% battery life, then suddenly die. When I turn it back on it'll show 3%. If I charge it, it'll go from 3% to 100% in less than an hour which is quite impossible. But after a reboot, the battery will show something around 5-10% again. I really have no clue what todo or what the issue can be. Please help!
I'm currentled running Android 4.0.4 stock, non-rooted and barely any apps or bloatware (Just whatsapp, messenger and snapchat)
I have had the same problem as yours, i got a new battery and all good since. Maby you got a new faulty battery. Is it oem?
Exactly the same issue but I've tried a new battery yet
I ve got same problem then i replaced battery and since then it happened like 3 times (i was pretty mad!) but since then it works great...

Try caliberating your battery. And try changing your battery.
Battery changed and looks a lot better
