last night, i charged my phone until it fully charged and then i played with it for about 30 minutes which cause the battery to drained 5%, i turned it off put it to the table and i slept, and then when i woke up, i turned my phone on and guess what ? it won't boot up, i plugged it in to the charger and it boot up as normally it do, so how did it happen ? i didn't even touch the phone and as a matter of fact, the phone is turned off, how on earth the battery drained ? i think it has something to do with the kernel, im currently using pa 2..99-5 and franco kernel beta r238
this has happened twice

Because it was at 5% when you shut your phone down, this was estimated. The shutdown process itself is taxing on the phone. Plus there is a natural sleep current drain on the battery when it is powered off (this is how it even knows you push the power button) I wouldnt worry

I think he meant it was at 95%
OP:
I'd assume you had a BSOD.
BSODs waste a ton of battery.
Using underclocking/undervolting/hotplugging?
How would he have a system failure drain, when the phone is turned off?

It could have crashed in the process of shutting down which would have appeared to have turned off but instead was running in a loop with the screen off and the buttons frozen.
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.
I personally use witchcraft to keep my batteries in working order.

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

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

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.
So I am on the WWE of Nougat, version 2.41.401.41. I was getting abysmal battery life, at about 2h30m screen on time, without doing anything special (just browsing, some social media, etc.).
Also, AccuBattery was showing the battery capacity at 2300 MhA, which I found quite impossible for a one year old device.
I suspected that my battery was badly calibrated. What I did is what is described in this thread, slightly modified:
Charge the phone while turned on up to 100%.
Remove the charger and reboot the phone. Upon reboot, the battery will have dropped at about 96-98%.
Reconnect the charger and charge again up to 100%.
Remove the charger again and reboot the phone. This time, the battery will have dropped again, but not as much as the first time.
Repeat steps 2 and 3 until after reboot your battery remains at 100% or at least 99% (depends on how freaky you want to get).
After doing the above I have been getting about 3h30m to 4h00m screen on time and AccuBattery is showing about 2700 MhA battery capacity.
Seems that HTC has really messed up the battery calibration on the 10. Hope this little "trick" helps you as much as it did help me.
----------------------
A follow up to this, here is a reply I got from HTC support, regarding battery:
* For battery calibration :
please unplug the phone from charger - turn off the phone device - press on Volume up + Volume down - Power on button all at the same time till the phone started on , please check the battery indicator ,then follow as below :
1. Restart your device
2. Turn on Airplane Mode
3. Connect your device to the charger, and charge it fully
4. Set screen brightness to Max.
5. Set Screen Time out to never.
6. Dial *#*#3424#*#*, choose battery and Charging run down test, and follow the instructions.
If the device loses more than 40% of battery in an hour, then send your device to the repair center

Fair enough, it's a bit pointless at this point to be honest. Does the phone reboot randomly below 50/60% or has calibration fixed that issue? That's the biggest gripe I have with the Nougat update at the moment. If calibration fixes it, I'm gonna do it now! If not, do you reckon another kernel fix it?
Thanks for replying!

For me the htc tool is showing like 6-7%discharge over the one hour...
But if I I use Spotify or any other online/local music app, this can't be true...
Seems to be a software problem, nothing to do with nougat or oreo, nor with firmware version.
Trying the "manual" calibration tomorrow.
About the 40% rule... I already had a support guy say it only needs to be 25%...
Still my battery is far far away from that... Sadly, would love to send it in to have a fresh battery...

from my understanding you are referring to the 40% in the quoted text
so when you do the test it should only lose about 25% in one hr like the HTC rep said to you instead of the 40 quoted by the other forum user?

Right, I am in contact with the HTC support using their FB chat.
Last time I asked, still on HTC One m7, it was around 40% for me too.
This time they said it should not drop below 75%.
To be sure you should ask the support yourself, maybe it depends on the country as well?

Have you tried wiping the cache partition, my battery was 100% & went to 81% and held its charge for much longer, it's a short way of clearing your battery stats
Another trick
I found an alternate trick and it looks like it's a bit more effective (at least for me):
Basically following OP's instructions: charging it to 100% then turn the phone off. But instead of restarting, Turn OFF the phone then hold power+volume down until the backlight of the back and app switcher buttons flashes twice then let go. Then turn on the phone while holding volume up. I think this helps force a battery recalibration every time.
When I did it once I got to 78% then the second restart 55%. I'm currently charging for the 3rd restart to see if I can get better than that. Previously when I tried OP's method a few days earlier I got 78% on the first restart , 98% on the second, and 99% for every time I tried after that.

Did you unplug the phone before turning it off or did you keep it plugged in?
have you guys tried the Chargie app? It's coupled with a hardware device that limits charging to the phone at your desired level and saves the battery long term.
Unfortunately none of the above did the trick for me. Still, the phone randomly (once in a while) goes to loop when 15 to 20 percent of charge is remaining and won't stop before I plug in a charger. /sad face/

Well the test consumed around 50% of my battery. The issue that started around a month ago is that my phone shuts off around 30% battery , however it won't switch on again till I plug-in the charger and when it is on , the battery is at 1%. Seems that the phones is displaying a 1% as 30% before shutting down. What should I do ?

Mind I ask how mch htc chared for this service?
Was it in US?
Thank you. :good:
Mine is currently sitting at,
according to accubattery at least:
on P - 66% capacity
on N - 75% capacity
Ok guys,yeah it's 5 years old already.Few days ago I noticed then when I charge it to 95-100% and leave the tablet turned off,when I turn it on battery looses like 10 % over a day and so on,so battery is draining when the tablet is turned off.
What can I do,I mean I can take it to a friend of mine who is pc technician but what can he do?
Possible hardware failure or battery issue?
If the battery has lost much capacity it will still charge up to 100%, but discharge much quicker.
If screen-on time is still okay, some peripheral component may not switch off when powering down. Some custom rom had messed up an old phone of mine and even after flashing stock rom the battery drained by 50%/day after switching the phone off. I even ordered a new battery to no avail.
If the Note hangs up or freezes during power off, you'd need a hard reset to power it on again and the battery would be completely drained in less than a day.
Self-discharge on my Note is extremely low, about the same as if i would store the battery separately or with a hardware power switch.
Screen on time is terrible like 2h or so...which means battery is bad,right?
Bad battery or bad configuration. The latter if the Note is drawing more than 1000mA when idle with screen on.
My battery still lasts about 7 hours (screen-on) and is the original from 2k13.
Battery lasts for like 6 h,and it's draning power when is switched off...I'm not sure how much but maybe like 5 % per day...
And I also noticed time and date is fuc..d up...
Can this be resolved?
So now even new battery can not last more then 4 hours,today tablet turned off at 30 % battery,I got flashing blinks and it turned off.
When I charge tablet it doesn't charge like in the start for 8-9 hours,usually 4,5 at max and when I check on status I see 70 % and then in a second 100 %.So smth is pretty messed up..
Seems to me it's for garbage only...
The Android Coulometer could be ****ed up. Although that should be more of a database than a driver, you could repair it by flashing the Coulometer driver via ADB. Only for stock rom. And there was only a guide for my old Huawei Mediapad on how to perform this.
A complete factory recovery in Download Mode will have the same effect. Or it may just slowly get better with time again, as it did with said Mediapad.
I once experienced real drain in soft-off state of an old phone, about 50%/day. A new battery didn't help. And the phone did really switch off, otherwise you'd have had to press power for 10s instead of one, for a cold boot. And with even higher drain.
A custom rom may have flashed a wrong firmware into a peripheral chip's flash. In case of said phone i suspected the wifi/BT combo chip, which retained a custom rom's bug even after flashing stock rom in D/L mode.
I was told that this is hardware issue.
What is factory recovery and what will it do,and how do I do it?
2.I can't update to android 5.0 at all.
When I click update manually get msg: you have recent update smth like that...
