tldr: My Incredible drains battery when turned off :-/
I have an HTC Droid Incredible that I use for testing my developed apps, and for playing around with people's roms, and I have found an odd issue with it. I can charge up the battery and use it for hours and hours and it consumes what I would consider a normal amount of charge, but when I turn it off, it still consumes battery charge. I'll charge it to 100% and disconnect the charger, hold the power button and select Power Off, and when I turn it on the next day the battery is very depleted. Yesterday I did this, and this morning about 16 hours later, I turned it on to see a 23% charge. If I leave it for more than a couple days, it won't even turn on at all and I have to charge it again before I can do anything with it.
I've tested this over the past few weeks with two separate batteries (one used, one brand new), and the same thing happens with each battery. It's definitely the phone and not the battery, because I have taken the batteries out completely, waited a few days, and they stay near 100% charge.
Some history on this phone:
I got this phone from a friend in a semi-working state. I couldn't root, s-off, or really do anything with it, so I did a factory reset, messed with it for a while, and finally decided to follow the steps in this thread to "unlock,downgrade,and achieve s-off with htcDev". This has allowed me to mess with roms, etc, so I have installed a couple, and now have "inc-eng 4.1.1 RC2" installed from this thread, and this kernel: "[email protected] #64 Mon Sep 3 18:55:57 EDT 2012"
The issue at hand however was happening before I even had it in my hands, as my friend described the same thing happening to him (he did not mess with rooting, roms, etc).

Maybe the battery is bad... take it out of the phone at 100 and leave it overnight and see what happens life wise

Thanks, but I did test that, with both of the batteries I have. I've left them for multiple days out of the phone, and when put back in they show 95-100%.
Maybe it's not turning off all the way.
Here's another test: turn it off, remove the battery for about a minute, then put the battery back in. Turn it on the next day and look at the battery level.
Might be a ROM issue. What ROMs have you tried this with? Have you tried stock sense and CM7?
Will do, I'll post tomorrow with my results.
If you have fastboot enabled then the phone is never really off. Try charging it then pull the battery, and put it back in the phone but leave it off. Turn it on latter and see if there was any battery loss. Fastboot is like hibernation. Its possible that some app is misbehaving and trying to sync or something while its hibernating, draining the battery.
Alrighty so yesterday I charged both batteries to 100%.
Battery A stayed out of the phone on my desk.
Battery B I removed from the phone, waited 10 seconds, and put back in the phone (I did not turn it on).
This morning, the phone (with Battery B in it) would not turn on until I charged it for a few minutes, and displayed 0% charge when it finally let me turn it on with the charger connected.
This is so weird...
Also, the rom I'm using doesn't have a fastboot option that I can find.

Okay so Battery A I put into the phone at 4pm yesterday, turned it on and found it had a 73% charge. I then turned the phone off, waited a few minutes, put the battery in and left it on my desk. This morning 12 hours later, I turned it on and it has a 25% charge.
I'm so confused... if I don't turn the phone on, how are the batteries discharging? Both batteries keep their charge when left out of the phone for a prolonged period, but discharge when in a phone that hasn't been turned on. Bah! >_<

Mabey there is a short in your phone somewhere. Does the battery last like normal when the phone is on, or does it also die quickly?

I'll have to test this when i get home, but I beleieve the battery discharges at a normal rate when the phone is on.
(this is not my normal phone, just one I use for testing apps, etc. so I don't use it on a regular basis)
I'll charge one of the batteries to 100% and leave it on overnight, and post my results.

Mine drains when all the way off 2 but not that bad... I think it may be the MotherBoard keeping power to the Nand memory so it dosen't relock and keeping power to the CPU so it can be quicker on bootup

I'm assuming there's no way to stop it from doing this?
It's not a huge deal, as this is a test phone I use for development, but I may be eventually selling my test phones, so I try to keep them in good working order, or get them to a decent refurbished point Plus this is a weird enough phenomenon that I figured it deserved discussion.

In the morning, I take the phone off charge at 100%, and it will then drop to 90% within the first 5mins (with no use)
Sometimes it charges until 90% and the light goes green and it does not continue charging to 100%.
To fix this I have to take out the charger and put it back in, it then charges to 100% like it should.
Anyone else have this problem? Its really inconvenient, if its not a software issue, should I cal t-mobile to have the battery replaced?
Thanks
I'm not sure but try this: uplug the power, restart the phone and then charge it and see if fully goes through.
Someone here once wrote that if he restarts the phone while charging it (he was talking about the Hero btw) it doesn't register the correct battery charge!
Just a thought. If that doesn't work then call them to replace the battery/phone.
I read somewhere else that the phone does not trickle charging once it is full, so what is probably happening is the phone fully charges, then gradually loses some of its charge, though I'm not 100% on that.
Ah just found the link where I read about the charging issue http://forum.xda-developers.com/showthread.php?t=658338
I have seen mine do the same (once) except it went from 100% to 91% - literally in seconds though.
Some have said it's a bug in the Android OS (?)
I found updating to fw .11 has made a difference for me.
I also removed Sky Sports news app ( not sure if coincidence that it's ok again since doing both those)
May install Sky app again to see.
Sometimes apps can cause problems.
How do you check the specific level of the battery? i tried pressing it in the top bar but nothing....

Yep, upgrading the firmware and removing apps can improve battery performance.
I would suggest you pull out the battery a few times and then try a full discharge/charge to reset the digital circuit of the battery to improve the state-of-charge estimation.

Hello, I will try a complete battery drainage, til it wont switch on, and then see if it is fixed.
So far my full drains have been to 1%.
I will report back

Ny phine only charged to 98 last night its now 94% after 20 mins. I hot it up to 100 but that quick a drop is not right. It's now 92%!
Ok, so last night I ran my phone down til it switched off, switched it on again and waited for it to turn off. I did this continuously til the power button no longer worked. I then took out the battery and replaced it. Then I put it on charge without having the phone switched on.
Turned the phone on today and it was at 99%. Its now 95% so the charge seems weak, but it seems to have improved since the 90%?
Maybe after a few more full calibrations it will be fine. I will try this for another couple of days and see if it helped.
After 2 days of running it down to 0 and charging while switched off, I got good battery life with the charge holding up to 100% quite well
So today I decided to charge it while it was switched on, and it charged to 100%, a couple of minutes later and its below 90% again!
I don't know why this is happening because it seems to work fine when charged while switched off, but not when its on.
What should I do?

Exactly same thing happened with mine this morn and I definitely became alarmed. It only charged to 99% when on and the charge fell very fast to 90% within 40mins of just standby - not even WiFi on.
So then I charged it to 99% while on and then switched it off disconnecting and reconnecting the charger. Turning it on 5mins later, it was back at 100% again. Browsed web using WiFi and updated all apps and widgets for 22mins continuous before it dropped to 99% this time. Been fine since.

T-mobile think its a problem with my battery and are sending me a new battery to see if that fixes the issue. I will post back with an update on the topic when I get the new battery in a few days.
On the phone keypad, if you dial *#*#4636#*#*, you will be taken to a testing menu. In this menu there are options to see phone and battery information as well as usage statistics for apps.

Same thing I described above repeated itself this morn except that the charge dropped to 93% within 12mins this time - on standby with airplane mode and no WiFi or Bluetooth enabled. However, It's held steady after that. I poll battery charge, voltage, temperature and usage levels using the Testing notification icon (I use the BarControl app).

I'm obviously missing something here and your post isn't very clear. Why would you need to root your device just to use an extended battery? That doesn't make any sense. All you should have to do is put the extended battery on a charger and charge it until it is full and then for a few hours more initially, unless the directions state otherwise. Afterwards, insert it in the back of your EVO, turn on your device and voila! If your device isn't functioning after doing that, assume you have a defective extended battery and return it to where you got it from.
Your gonna have to go through like 5-6 FULL/discharge sessions. Charge it for like 3 hours after it hits 100% and then disconnect it and dont charge it UNTIL it completely dies. Then do it again like 5 times.
Everyone keep saying I should root my phone for it to work correctly
Thats so you can install a SBC Kernel but forget about that. Just do the full charge/discharge cycles and your battery should be good in like 3 days.

Iight Imma do it that way now
Even HTC said do NO fully discharge your batery, so I'll take anyone that poists that as bad information.
Here's what works for me:
Here's what I do, and I get PHENOMINAL Battery life.
There are two ways of conditioning a battery that stand out above the rest, and I combine them.
Download the battery monitor widget/app
Set it to your battery's maH in settings.
This isn't totally a needed step, but is a useful app.
Charge your phone until full.
Unplug it, turn it off, then plug it in for one hour.
Turn it on for two minutes, so it fully boots.
Turn it off, unplug it, when the light goes off, plug it back in for one hour.
That part of this is actually from HTC, on how they found the best results for charging.
Now, before you plug it in, unplug, wait for the light to go off, plug it back in.
When the light turns green, unplug it again. Repeat that step 10 times.
(It may not take 10, it may take more, but 10 is good)
While plugged in, boot to recovery, wipe your battery stats.
Then reboot to system.
A good habit to preserve battery life is to keep mobile data off, unless you need it. I used to turn wifi off, too, but lately, I leave it on.
How good is this?? I take my phone off the charger when I leave for work at 7AM, and usually, I go to bed at 11PM, when I charge it back in, and it's never below 80%, unless I've been really using the phone excessivley.
The other thing is, I do this, somewhat daily. I wake up, tuen the phone off ,so my alarm doesn't keep ringing every 15 minutes, unplug it, then not turn it back on til just before I leave, so it's getting that "treatment" at some level, every day.
ok but how do i wipe my battery status?
You have to be rooted to wipe your battery stats. Just do what i said byt dont let the phone fully die then. Let it get to like 5% or something then FULLY charge it for like 2 hours after it hits 100%. Do that like 5 times. What the other dude said will work too. Just do what your comfortable with.

yeah im doing it ur way now
I'm having a very interesting issue with my HTC One. When I power the phone completely off (ie: Hold power button, click power off), the battery still drains when left alone for a few hours. I'd except maybe a percentage or two drained when the phone first boots back up, but its kinda unacceptable that in ~12 hours the battery goes down 15+%!!
Last night, at 8:00PM EST, I turned off my One with a bit over 80% battery remaining. I even rebooted into recovery this time and hit power off to ensure that the phone wasn't doing some crazy deep-sleep hibernation junk. This morning, at 9:00AM I turned the phone back on and had 63% battery! About a 20% drain for 13 hours of completely powered-off sitting on a desk? I've attached a screenshot to further describe the issue. I'm at a loss for this one. With my usage, the phone honestly drains the same amount of power with the phone off than if I just left it on!
To add more confusion: When I first got the phone (Monday after the launch), I didn't have this problem. I'd turn the phone off with 100% once it was charged and 12 hours later turn it back on to 100%. A week or two into using the phone, I started seeing this. I thought it was something weird with Stock, and Googling suggested that the HTC One had some deep-sleep hibernation mode to make boots faster, but after installing CM10.2 I have the same issue. Even with powering the phone off from recovery!
Any ideas? Anyone else noticing this? Is my One defective? (I hope I don't need to send it back.......)

You have to go into settings>power and uncheck fast boot. With this check it kinda puts the phone into hibernation mode and it never totally turns off.
My solution above is for a Sense based ROM not sure what may be causing this running a CM based ROM. Kernel maybe????

I did this while still on Stock; didn't change anything. Note that I'm now on CM10.2 where Fast Boot isn't a thing. Also, powering off from recovery should negate any hibernation, which I tried last night and still saw a 20% drain in 12 hours!

That's what I'm thinking, although what is weird is that usually batteries are either defective on day 1, or degrade over time. It's weird that in the course of a week or two I went from a seemingly perfect battery (maintained charge while powered off) to a terrible battery.
To make matters weirder: I'd expect more than terrible battery life while the phone is on, although I'm not seeing anything excessively bad. This is going to be a nightmare trying to explain to VZ, especially because I can't just tell them I've diagnosed with CM10.2 and a custom recovery. What sucks the most is I'm (more than likely) going to get a "certified like-new" phone back... ugh...

Yeah, I feel your pain GOOD LUCK:fingers-crossed:
This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/verizon-htc-one/315416-how-clear-cache-partition-stock-recovery-un-rooted-phone.html
Check your battery history in settings. If the 3. bar, in the middle, is always there (it's probably called "in usage", I'm on a different language so i don't know), then some app is always on and it's draining your battery. I haven't discovered which app is that yet, but I'll install battery monitor app to discover it.
When it's like that, i lose 1% per hour on standby, which is a lot, because normally during the whole i lose about 1-2%. So I kill all apps with Clean Master and then the 3. bar isn't present anymore when my phone is on standby.
And why not just let the battery die. I mean let the phone turn off and then charge it to 100%. This is the general way to calibrate the battery.

Now you're talking crazy. I'm fairly sure the same advice for NiCd and NiMH still applies, even though they're completely different technology and haven't been used in phones 15 Years.

Lipo batteries are way different than NiCd and NiMh and their chemistry is unstable to say the least. But by all means be crazy yourself and drain your battery to 0% if you feel the need.

I think you missed my sarcasm, I agree with you.
You can't drain the battery to 0 without going out of your way as the electronics in the battery protects it, but yeah, as soon as your phone switches off, it's time to add some charge, if not way, way before. I don't actually believe in this calibration thing people speak of.
I ran my M8 completely dry once on purpose a couple of days after purchase. I always do this at least once with every phone sometime in its lifespan.
When doing so, the phone sat at 1% charge for over an hour while I had the screen on at maximum brightness all the time and streaming music with Spotify.
Needless to say it was needed for my phone.
While using the phone, battery doesn't drain as fast.. When its in standby, somehow it drains faster..very strange

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/ve...partition-stock-recovery-un-rooted-phone.html

Tried this. It did seem to work for me. I was skeptical, but I definitely feel like it fixed the erratic battery behavior I was seeing.

I ran my M8 completely dry once on purpose a couple of days after purchase. I always do this at least once with every phone sometime in its lifespan.

has this process worked for you for every device you've owned? I'm getting horrible standby drain on my m8. Wifi on, location, autosync, bluetooth, nfc all disabled. in a span on 9 hours I lost 10% close to 11. the only thing I can think of is I haven't greenified anything, but I shouldn't have to..
and like another user said I seem to get better battery life when it is in use then when it is in deep sleep
1% battery drain per hour is about normal. If you don't want out to drain turn it off

it shouldn't be if you disable everything.

According to HTC tech support, the battery in the One has a chip that tracks charging/discharging. This chip's memory is cleared via the specific steps I outlined (both volume keys and power button cycling). It's important to do this process while the phone is plugged into the HTC charger that came with the phone--not an aftermarket charger. Apparently, the charger chip is also affected by this reset.
I performed this reset procedure a few times, cleared the device cache, did a data reset, and also installed the new OTA. None of these steps completely corrected my erratic battery behavior. I'm sending the phone back to HTC for a replacement. In researching this, it appears that after the prior KitKat OTA several weeks ago, a number of folks have complained of the same power problems on various Android boards and I believe HTC is aware of the problem.

Its an electronic device that is running. Should it be magic and use no power. At 1% per hour thats 100 hours of standbye time which is not bad. I agree you should be maybe a little less with all location services, data, 3g, wifi, bt all disabled but remember. Its on and using power, it has to use something.
Hi there, i have a problem with my battery, when the percentage is 15% the phone starts discharging very quickly, like dies in 1 minute. From full charge to 15% discharge seems legit. In your opinion can be an hardware or software problem.
Hy, my phone dies at about 15-20% but when I plug it in the charger it says 20% and charging.... I turn it on and the same thing happen...
ANy help on how to fix this problem?
Thank you

Did you try the procedure described in the first post, for which this thread is about?
Question,
I was trying to follow the procedure for battery reset. I did this in the past when I got the phone. Since then I I unlocked bootloader, rooted and S-Off. Now when I try the volume up/down + power, after a few cycles of the logo screen it goes to bootloader screen. Cant' get it to go the 2 minutes mentioned. Any ideas?

I tried the procedure and the phone kept restarting like every 10 seconds through the process.
There is no Fast Boot option on Marshmallow, so that's out. I'm leaving the phone to charge overnight.
In my case I'm afraid there's a certain App that's creating the drain because the battery was showing 20%, then 50% while unplugged and then it died 15 minutes later while I was reading the newsfeed.
I will edit this post with the results in a couple of days.
Updated: Ok sooo, the first charge after calibration lasted about 12 hours with moderate/heavy use.
Now I recharged again and I don't understand. It has stayed at 100% for more than 15 hours!
I have Amplify and Power Saver settings for vibration and dim screen and that's it. I don't get it.
As a final note, HTC recommends doing this chickenchocking thing every month! I felt like I was killing the poor thing trying to boot. But anyway, that's my results so far. Oh, I'm using Gsam for readings.
My Note 4 is 14mo old and for the last couple months it just shuts off on me even though I have plenty of power left.
I am a light user and usually have enough power for all day use. I rarely use my phone down past 10-15%. I always put my phone on the charger when I go to bed at night when I have somewhere around 20% charge left. If I notice that I might not have enough power to get me through the day I'll put it on the charger somewhere between 30 and 40%.
Lately, like tonight I got a low battery warning at 30% power while I was on the phone. Not even two minutes later it shuts off. When I turn it back on it starts to boot up but then shuts off again. When I put it on the charger it was completely dead. This only happens 3 or 4 times a month but it's annoying because often it happens at the most inconvenient time.
I've also had it shut off and then when I put it on the charger it starts charging at 28% power.
Please let me know what may be going on here and a solution...
Thanks...

I had the exact same issue. I had 2 different batteries shutting off at 20-30%!.... Replacing the battery to a brand new one simply fixed it!.... if you are going to order one online try to avoid unknown brands . Also, pay attention there are some fake Samsung batteries claiming to be authentic.
Also if you still have warranty, contact Samsung and they should send you a new one. That's what i also did.
So you think its the battery and not software related? I was thinking software issue because I don't abuse my battery by running it dead and it's an intermittent problem.
I know that the life cycle of Li-ion is greatly reduced by repeated draining to below 10% (my kid's phones suffer from that. Seems like they can't make a battery last more than 6mo) but I've never had a phone battery go bad on any of MY phones including my old Note 2 even after two years. Maybe I just have a bad battery?

Doesn't matter whether you abuse the battery or not. Some batteries just go bad faster than others. I also think it's your battery.
A factory reset without restoring apps will rule out a software issue though, but since we can't root, it likely isn't anything messing with your battery percent unless it's just an app draining your battery. But even if it were the latter, your battery wouldn't die then start charging at 28%.

Pretty sure this is an actual built in feature. Mines always died at ~20% (since the 5.1.1 update) and once plugged into a charger and rebooted all my running apps and clipboard info is still running as if the phone never died.
My battery is brand new (from warranty replacement) and it still does this so this is why I think it's a "feature" to keep you from losing data in the event of a low battery event. Just my opinion.
It's not a feature. Mine goes all the way to 0% before it dies. I once read to take out the battery, hold the power button for 30 seconds (while the battery is out), then put it back in and see if it helps. This supposedly gets rid of any residual power storage. I don't know if this is a placebo affect by after I did that, my battery now goes all the way to 0 before dieing.

Not exactly a placebo, but not sure if it truly helps. Doing this would clear all electricity stored in any capacitors in the phone. I'm just not sure how this helps.
And my battery goes all the way down to 0% too. It's not normal for the phone to due at any other % (except maybe 1%).
