I urge everyone to just do this simple test and report back you may have this issue and not even know it.
Hey everyone at xda, currently i have come across an issue that some of you may have without even knowing it. I realized when i was using tweakr I pulled my battery, but when i put it in i never pressed any buttons,the phone was off battery back in no buttons press and it turned itself on
I wish to get a tally up how many people are afflicted by this problem. It has not yet affected me performance wise, but i am concerned with long term affects as well as the possibility to turn it off when the situation calls for it.
TESTING
1) Ensure the battery is sufficiently charged (obvious but I am mentioning to be through)
2)Ensure you are not connected to your charger (my phone operates normally when connected and does not automatically boot)
3a) Power off the phone by the power button
b)or pulling the battery. Wait 10 seconds before placing the battery back in if you pulled it.
4)Wait it may take a few seconds but we may want to try for 1 minute to be sure it is not there
5) Report results in the poll and comment
I would think it would be a good idea to post your phones information if you are having the issue.
Such as rom, kernel, radio (ril matched or not) , desire Z or g2, and hboot(if known).
Other information is welcome to.
I have been going through several radios, roms and hboots and this has never happened to me.
Desire Z
My Desire Z auto booted. I'm running CM 7.1 RC1.
Hmm interesting i noticed mine when i started using MeXDroid mod pre ghost chilli.
Did you try anything so far to try and fix the issue. I think it would be a good idea to gather all the information possible.
Also mabe we could brainstorm ideas.

Using the current MIUI release, I just noticed this a couple of days ago. When I power down using the power button, it will reboot itself in a matter of seconds. The same thing just happened with a battery pull.
Sent from R2's G2 using XDA Premium App
mine didnt auto boot
rooted
I think that this might have something to do with the battery calibration procedure. My Z did power off normally when I did the calibrating procedure about two weeks ago. Since then I haven't tried to power it off until now. I have only installed a few apps and upgraded the radio to .30 since I did the calibration.
Same issue here. DZ.rooted with g2 hboot. Latest bell radio. Cm7 nightly 136.

Happens to me regardless of which ROM I use (Tried CM7 Nightlies, and Vision Sense 2.3.3)

GREAT NEWS!
as posted by edkeys in cm7 nightly thread, drain your battery to 0% and let the device turn itself off completly dead, plug into charger and let it charge ~4 hours or until your light turns green. unplug charger, phone will boot, load up your rom, power down, AND IT STAYS OFF!
^lol i was trying that one to but for some reason it did not work for me... i may have made a mistake somewhere through and unplugged when it wasn't 100%yet (light was green though)
I am trying again later and it it works ill quote you in the first post =D
My phone started powering off normally again after upgrading to the latest nightly. Didn't even need to do that battery drain procedure.
what was changed in the nightly? i flashed a sense rom, miui, and new hboot and radios without it being fixed. i did the battery drain trick and that worked. so im curious as to what cyan changed in one nightly...
I did the battery drain with the latest MIUI and it was a no go. I may try again though.
I don't think that the problem is ROM related. I didn't have the problem initially with CM 7.1 RC1 but after I made the battery calibration procedure for the first time the problem started. Then I upgraded to the latest nightly (138) and the problem was gone.

After the phone shut down, when you plugged in the charger did it automatically reboot because mine does -.-
so ya.... still rebooting after charged to 100% from 0% and unplugged from charger
I drained the battery to nothing, plugged in to charge, and after less than 5 minutes, turned the phone on, to charge to 100% (I needed the phone on for the alarm clock). This seems to have fixed my no-shutdown issue. That was on nightly 132. I am now on 137, and so far, so good.
While on the subject, is there an app that specifically uses up the battery to drain faster? ie, turns on absolutely everything, and really drains it fast? Might be handy for battery calibrations.

I've just found that on the desire forum, do you think it will word on ours HD2?
vidler said:
Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.

my guess will be no on this. As i think that the batteries are different. and it might be something with batteries that are in droid devices perhaps.

I'm trying right now i'll report as soon as I have an answer!
I think it should work as it's wiping battery stats in android
im trying it too as we speak
I'm pretty sure that calibration will not work currently in android properly. Cottulla posted a few days back that the battery driver is still incomplete and currently only supports reading battery state and that the write too part of the driver has not been implemented. When the driver is complete and has full read/write battery function this procedure should work better.

thats' true i didn't know that . it may be impossible to wipe battery stats this way

My battery wasnt calibrated properly and wudnt charge over 90%. Someone in this forum told me to switch off and charge until green and then switch it on. Now my battery seems calibrated plus i got 2 days of use on moderate use

but ive seen several posts of people calibrating their battery in winmo and reporting better battery life....idk maybe placebo
i will try this too. i myself had an issue today. i'm using chuckyrom right now. i use it at work so i can turn the "phone" off while at work. so it is in airplane mode. i only used the phone today to check the time and played some uno on a break. my battery stayed on 100% for 5 hours. so i turned the phone off, took the battery out for 1 minute. put the battery back in and turned the hd2 on. it was still on 100%. 4 hours later it was down to 94%. i just didn't think that a true battery reading. most days when i have the "phone" turned on at work i only have 10% battery left by the end of the day... just seemed odd to me. idk.
Well, I don't know if this works 'properly' or not but it's certainly had an impact so it's doing something right.
Prior to the calibration I could only charge to 95% or so. Phone now seems to be charging to 100% all the time which is good. Battery life also seems great, not sure if this is down to the calibration or not as I moved to Darkstone V2 (16/08/10) release the day before so don't have a baseline.
FYI, as I type this I'm on 49% battery remaining after being unplugged for 10hrs. Fairly light usage, couple of calls; some texting but quite a lot of browsing and XDA App on 3G and WiFi.
Amazing progress the devs are making. Have been running various builds of Android for a week or so no and haven't yet had to revert to WiMo.

Anyone able to do this with mattc Leo + Froyo w/Sense? The charge indicator LED never changes to green.

Yeah, its hard to remember to take a screenshot before you plug it in (or in my case...reboot the phone)
You may want to try BatterySnap...its a free app in the market which gives you a great battery widget, plus a lot of really useful graphs and information.
I upgraded to Froyostone on the 12th...thats why the information is only going back that far...but as you can see, 18-19 hours a day at moderate usage is what I am getting on a regular basis
Cheers

Power the phone off...then charge till you get a green light (Maybe even for an extra 10 minutes or so)...power the phone back up and plug into your charger. now it should charge up to 100%
I dont know if the battery itself is limiting the charge, or if its just the battery meter that is not displaying correctly...Anyhow, the above method corrects it for me whan this happens on my phone.
Thanks matey . I've only had my HD2 for five days but thanks to the awesome resource that is the xdadevelopers forum, I'm successfully running Android on my phone. :-D

Just to confirm, I'm on ChuckyDroidROM with mattc Leo + Froyo w/Sense 1.5b.
- I can charge to green when the phone is powered off.
- I cannot charge to green in ChuckyDroidROM WM (says 100 in Battery screen, just no green LED)

Hi i am on ChuckyDroid ROM 2.12.50 Radio and darkstones 2.1 build.
have don successfully the trick in post 1.
Now having 100% in the taskbar and i will report if the battery life have improved.
I bought this Hero off eBay, and it was dodgy since the begining.
The phone had cyanogen, and was restarting itself occasionally.
So i wiped it, installed 2.1 and it got fixed, but now i have a problem with battery drainage.
Its insance, 10minutes-10% im pretty sure its not supposed to be like that. with or without wifi/3d turned on, its just riddiculous.
I borrowed battery from a friend, and that didint make any change, i installed latest update from the autoupdate in the phone and still its bad. I read somewhere here that its faulty email app that keeps on trying to sync and drains battery, how do i fix that ?
I did a full wipe, cleared cache and everything back to factory settings, with no apps installed it goes from 100% to 0% in an hour.
I downloaded 2.1 from some android forum, as i was unable to find one here (there are only links to 1.5 on the xda.wiki WHY?)
If you can point me to a proper 2.1 (or higher?) software to download that doesnt do this crazy **** i'll be happy as infant on crack.
Please help, here is my software information:
Firmware: 2.1-update1
Baseband version: 63.18.55.06JU_6.35.09.26
Kernel version: 2.6.29-063c4d24
Build number: 3.32.405.2 CL191507release-keys
Software number: 3.32.405
Browser version: WebKit 3.1
Try calibrating your battery it gave me a huge boost on my hero... went from getting 16hours day.. to about 30hours on a single charge!!
Every time you flash a new ROM you need to calibrate your battery. The battery meter in the OS (Android in this case) is generated based on the battery stats file.
Battery stats is erased when you flash a new ROM.
Easiest method of battery calibration when you're intending on flashing a ROM:
Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.
Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.
Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.
Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.
Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.
The last part, run until completely dead and charge only needs to be done once in a while (this is calibrating the battery innards, not the battery stats)

hah, yea thats what i accidentally figured. phone was switching off, but when i powered it back on it had 30%.. and it was like that 3 or 4 times.
I ran it down completely and now am charging it till max, we'll see what happens. at worst i'lkl start your process from the beginning thx !
I diidnt know you had to do that. i've been playing with my G1 and not even once i had to calibrate that.. maybe i should
How'd it go? Any improvement on battery life?
it diidnt help I did what you quoted step by step and its still running down the battery like crazy :/ what else can i do ? im thinking of switching to 1.5 but thats just not progressive and my friends phone is running fine on 2.1, with the same battery even.
Edit: i've installed task killer and killed all the mail checking apps.. hope that is the problem
Edit2: it didint help at all, in 5 minutes i lost 15% fcuking hell !
I just switched to 1.5 and its still happening ! I using a different battery and its just as bad... why is this happening to me
ill try second to latest radio from xda wiki.. im running out of ideas,what else can i do ?
That really wierd... its not the battery if you have tried using different ones. Its not the ROM if u have changed it.
Have you tried disabling auto-updates? and auto-checks for emails. Which email client do you have? you should find the option to "sync-never" in the app settings.
Buying it from ebay is kinda ominous though.. was it described as faulty? perhaps you could contact the seller and request a refund is all else fails?
you can try using setcpu to underclock the cpu.
i have similar situation as you. before going to bed around 11pm, it showed 50% left, turned on airplane mode, then in the morning around 6am, phone was powered off.
now it has been 2 days, still have 20% left.

Did you ever take into consideration that some part of the hardware might be damaged?
Devices that got water damaged, sometimes show weird symptoms as well:
- They still boot up and seem to work well from the first sight
- The battery drains very quickly
- Some of the peripherals are not working stable or not starting up anymore (e.g. wifi, bt, gps)
- Other crazy things might happen as well (e.g. random reboots, backlight flicker, etc.)
So you might have a look at the mainboard. Red stickers indicate water damage!
Regards,
scholbert
Yea but if it were damaged would it show 50% battery after restarting thinking it had reached 5% ? i dont have the tools or will to unscrew it.
i paid 100 pounds fo it, the normal price of a used hero, but the auction said "phone restarts for no reason" and they do not accept returns, so im propably screwed :I
I had an old blackberry 8300 curve, i had it in the bathroom while i was showering, got too moist, turned the detection pads red but phone seemed to work fine after i dried it out. But the battery went to crap progressively in the manner. I would charge to 100%, take it off the charger and maybe an hour it would say less than 10%, do a battery pull and it would go back up to maybe 80% and last maybr another hour and keep doing that till it would normally drain on top od the numerous reboots i would be doing until eventually it would just drain and die.

Can dead pixels cause this ? i have like three.. but then again why would it show 50% after restarting from 5%..
the thing is its not draining the battery, just registering it wrong
Any updates on this? Any resolution?

sorry mate i have tried everything unsuccessfully and returned the phone to the seller.. dont tell me you bought it ? (london)
No, but i have a samsung galaxy tab and experience similar symtoms. It does not bother me too much, the battery life is still great. Just the percentage is off and i need to restart from time to time.
I read similar complaint from droid x forum too.
Hello everyone,
I rooted my phone in early september and put cyanogen 5 on it. I loved the new features but the speed wasn't very good so I switched to biffmod. That's when the problems started to happen. My battery life significantly decreased, I could barely keep it running for 4 hours. When I would open apps like google maps it would turn off instantly, but the phone and text messages worked flawlessly and I loved the speed so I didn't really mind. In the last few weeks it got worse. After a phone call the phone would turn off. I decided to reflash but it stayed the same. Now the phone lasts about 1 minute after unplugging from 100% charge. Anyone knows what could be causing this? or how to fix it?
EDIT : I'm using Biffmod 2.1 with 245 CPU minumum frequency and 556 maximum and DangerSPL.
is this happening on other roms or just biffmod??
Cyanogen 5 was working fine, only hapenned since I switched to Biffmod. (Which is using cyanogen 6)
do a nandroid (plug the phone in for this so it keeps power). then try another rom i say. we can then narrow down whether it is a rom issue or a battery issue. as far as i know no rom should give your battery a lifespan of 1 minute. make sure you have wiped your battery stats too. not sure if this will change anything but you never know.
Looks like a battery wipe fixed the problem. It got past the 1 minute mark! In fact I didn't even know that RA's recovery had that feature. Thanks!
no problem man. i figured it may have been something like that. if the stats dont match then it thinks the battery is low on power when it isnt.
False alarm, it did get better but it shut down after 30min of idle with wifi on.
ok. try a different rom to see if that helps or try draining the battery completely. keep turning your g1 on until it wont turn on any longer. then try charging it from there.
how long have you had the phone by the way?
I got the phone 1 year ago. I'm trying to drain the battery right now. I'll try switching rom after this. Do you have a recomendation? I'm on ebi1 radio.
not sure myself mate. i went for cyanogen, then went to superE as it suited my needs and aint changed since
Hey,
I have an HTC HD2 (obviously ), what I've charged to 100% last evening. I've switched it off (I'm absolutely sure I did) and when in the morning I've switched it on it indicated the battery was empty, it was 0%. Of course the phone switched off almost immediately.
I'm using Android 4.1.1 ParanoidAndroid 2.15 by Xlyo.
What do you think, what could cause this really huge battery drain while, the phone was switched off?!
Thanks in advance!
VDodi
EDIT: I've forgot to state I have had no battery issues before. Normal drain at all time, 4-6 mha during sleep.
Hello,
Was the phone/battery hot when it you touched it?
Could be as simple as a bent battery pin.
Good luck.
I did not notice anything unusual... besides it became empty
Anyway nothing extraordinary happened before or up until now, so... i do not know... perhaps just an error in the matrix
What do mean by switched it off?
If the display is off many things still can run, wifi., Bluetooth, , app update, a game...
If you mean physically off the hardware is cause as stated above.
What does 'current widget' say just after waking up?

Hey,
I mean the switched of as turned off (power off).
Btw. really interesting because I clearly remember the Android started up, but no logs have been made by the CurrentWidget I have a log entry from 0:01:16 and the next one is 22:37:29 (I charged the phone via recovery and only after went to Android again).
No unusual behaviour since then so maybe it was a coincidence.
Hello to all!
Since I don't have honor to post on main development page I need to post here in question!
I can't find nowhere something about battery life, I installed without problem ROM on my SIV and battery life is very poor. Yesterday I watched on YouTube MKBHD Hangout with Motorola CEO Dennis Woodside which have length of 39 minutes I think. My battery was at star 98% and at the time of ending video vas 45%. Battery can't last full day of normal usage. (it last from 07:00 to 18:00). At beginning I noticed this problem and I installed One Power Guard and its always on powersave or standby mode.
This anyone facing with this problem?
Yes mine is exactly the same. Running v4.0 and battery life is terrible now. Camera app force closes every now and then and sometimes maybe twice a week it reboots.
Plus I can't charge it switched off - everytime I plug it in it starts up.
Hi,
My battery is a little poor too, but it was because I was with my cellphone screen on almost the whole day... When it was an extreme case (when I was in 4.3 AOSP ROM and it didn't last even some hours, like you), I recalibrated it (I used to do it with my Xoom and X10 Mini Pro, it may be a placebo, but looks like it worked...
To recalibrate simply let your battery run completely out, then plug to the charger and let it charger completely while turned off (the white battery icon appears), then turn it on and let it run out again, then charge fully again. Remember that plugging and unplugging your device from the charger is bad for your battery, and remember to keep the screen brightness very low, turn off WiFi, Bluetooth and SPECIALLY 3G when you're not using.
Hope this helps,
~Lord

You need to flash v.6.0 which mostly correct FC camera app. I notec when i was runinng on ART reboots was more common.
My solution was to flash MK9 stock rom, this is the most stable and reliably by me so far.

Thank you for advice. I was using battery calibration on my Galaxy SI GT-i9000 and Xperia X8 and it was uselles. Know i didn't se enyware that i need to recalibrate battery so i didnt do that.
