So, my wife has a STOCK MyTouch 4g (2.3.4) that has worked well for a long time. She is a VERY light user, but, when she needs it, she NEEDS it
Recently, every time she has pulled it out of her purse, the battery has been dead. I have tried changing batteries, a new one, and one from my personal backup MyTouch 4g (also 2.3.4). Regardless of the battery and even with the phone turned OFF, the battery will go dead in a couple of hours. How can the battery drain when the phone is off?
What am I missing?
I did a factory reset on the phone and set it back up again. This didn't seem to help. I checked the features using the battery (settings -> about phone -> battery -> battery use) and it appears that the Cell Standby is still running even with the phone turned off.
Any thoughts?
Thank you!
Follow up
As a follow up:
1) I took a fully charged and known good battery (from my phone where it works perfectly well) and left it OUT of the problem phone over night;
2) the problem phone was without any battery at all overnight, so, it was OFF
3) I then checked the battery in my phone and it was still at 100%
4) I then put this battery into the problem phone and did NOT turn the phone on.
5) 10 hours later, I tried to turn on the problem phone. It would NOT turn on.
6) I pulled the battery and checked it. It was DEAD.
So, even when turned OFF, the problem phone is causing a drain on the battery.
Where should I start looking? Any ideas? Bad/damaged firmware? Should I root and flash this phone?
TIA

You could root and flash a new rom. But from the looks of it i think its a hardware issue. Maybe charging system issue.
Because a short circuit in the charging system or battery connectors could yield such a problem
Is your mytouch 4g made in taiwan?

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!

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.
Hi there,
I have had my SGS since Sept 2010, and have had no problems. A few days ago, the battery standby time dropped from a few days to 5 hours (and this was in flight mode). With the 2G phone on, and 3g/wireless/gps off, the standby was about 3 hours.
I removed the battery, and the put it back in, and let the 'phone charge whilst turned off.
Is there a way to mend this? Where does the problem lie?
Cheers, Peter.

might be due to a new software you just installed or upgraded.
Install some free tool to do the monitoring and confirm which application partially awake or prevent your phone to go to sleep mode.
Try System info
Exactly the same problem with me, I'm pretty sore the cause is update or app.
This is not the case. no new programmes were installed.
I noticed that when the phone is ON and charging the indicator states it is e.g 30% charged. I remove the battery charger, and the indicator states that the phone is empty and has to shut down.
Huge Battery drain post on this very forum worth reading .
But i would hazard a guess with a sudden drop its a dying battery .
jje
I had the same problem with u, i think u should back up your phone's data then use "Factory data reset" feature. I did that and everything's OK
SOLVED
Indeed, I did a factory reset and the problem went away. Battery life returned to normal.
Thank-you for your advice.
I noticed this a couple of days ago: I was in a place with no 3g nor wifi so I decided to switch O7 off. In the evening I switched it on and battery was empty.
I tried again yesterday with the same results. What"s using this phone while it's off?
Are you sure it is actually flat?
My battery has a problem, if i turn the phone off and then on it will show that my battery is empty and want to turn on battery saver. If i keep turning it off and on and mess with the battery contacts it reads properly.
Just a thought....
This is because the battery is cold, let it warm up and it will display the correct level

This happens after being on for days, it's not to do with temperature.

It also happens to me. Not usually but once every 1/2 weeks. I've been looking for a solution and the only one i found is switching off and on again until the battery level is ok. However i have to say that this has been happening since i installed 7740 update, so maybe the problem is that.
not actually drains...
I think the battery did not darain.
It is just the battery level is not displayed correctly; I had the same (or similar) problem. I switched off the phone while the battery was at 80% and the next morning when I switched it on I got the message "the battery is low..." and the wrong battery level displayed.
I kept it on for hours and it worked nicely; I noticed the battery info displayed 1% of residual charge and 7 hours of expected workng time...something weird
Suddenly after hours of usage the battery icon started to work properly.

Exactly the same as me. I'm on my 2nd Omnia handset now (warranty replacement) and this one does the same so I assume it's the battery that's faulty.
If you leave it on long enough the battery meter slowly increases over time until it reaches the true value.
Just installed 8107 upgrade via cab; let's see if problem have been noticed before and solved now
I noticed this problem also. After the mangu upgrade it is not there any more.
For me it seems that th eproblem laid in the firmware..
funny, I'm not the unique
Today I've tried to make an hard reset to see if the problem would have been solved. I'm on Mango 7740, tonight I'll try to switch off the mobile phone after charging.

I did a hard reset, OS update and then a handset replacement and the problem is still there.
I'm convinced it's a fault with the actual battery.
Ok, I yesterday evening I switched of the smartphone for some hours... Then I turned it on and I saw the"popup" which told me the battery was low.
I left the device on, with 3g on for all the night and this morning I found the battery level as it was before yesterday evening
I confirm the battery do not drains when the smartphone is turned off!

As I already said, this is because the battery gets cold when you switch off your phone, and it then appear drained. After heating up again it will recover it's charge.
Hello all,
Recently i've been noticing that my GS4 battery is draining too fast, i think that it's time to recalibrate it. Since my phone is not rooted, i have searched for guides on how to recalibrate the battery.. and i found this one:
To calibrate your Android phone battery correctly:
1-First drain your battery down. Let the device switch itself off naturally. You will know if it is completely dead because it won’t switch on again.
2-Place the phone ion charge while it is turned off. Allow it to charge for at the very least 2 hours, if not 4, until the battery meter reads 100%
3-Switch on the phone while the charge is still connected to it. When your phone is on the home screen, leave the charger connected for a further 2 minutes before removing it.
4-Repeat the above steps twice more, always allowing the phone to completely discharge first.
The reason for leaving your charger connected is to allow the configuration files to update with the new, correct charge values. Some of the best ways to avoid battery usage is to make sure all connections are turned off when they are not in use – Wi-Fi, Bluetooth, GPS etc. Make sure your screen locks down in under a minute when not in use and that your screen is not set too bright
My question is.. is it safe to turn on the phone while it is charging? is it safe to turn on the phone when it is plugged to a charger while it is off?
Thank you in advance.

Hi
Yes and yes
BTW I do not believe to much in those battery calibration methods , as far as i know a new file is generated each time you switch off and back on
You can charge your phone in any status, on, off, flight mode, playing games etc.It will only affect your charging speed.
As for calibration - I have heard about such thing and try to discharge my battery till some 1-3% and full charge at least once a month. Don't know if this helps. I think also important is the environment temperature and how you discharge the last percent.My suggestion is that last percent must be discharged as slow as possible - with screen locked let it die natural way, with normal usage, very slowly. I and other usually switch all possible things to drain battery faster at this stage. That seems wrong on my personal opinion.

NO NO NO
Draining your battery is BAD!!! Draining it below 0 is the dumbest thing you can do. That damages your battery. Whoever made that "guide" has absolutely no understanding about his battery.
Calibrating is easy.
Charge to 100%. Pull your battery. Put battery back in. Charge again until full when powered off. Volia calibrated.
Though it will probably not help. My guess is that you just need a new battery (if it's no software problem).
Hey everyone. So I bought a second hand note 4 recently and have been having battery problems.
I did a full wipe install of CM13 and the battery dropped to 0% at random times and I had to plug it in the charger for the phone to even boot as it would just restart as soon as it turned on. Anyway, i thought this is probably due to faulty battery. I purchased another one and now this one doesn't reboot at random times but seems like the phone keeps reading the battery percentage wrong, sometimes it doesn't charge over certain percent, just gets stuck at 77% or 63% or any percentage really. If I remove the battery and plug it back in, it shows a completely different percentage everytime. I have tried wiping battery stats, do a full discharge/charge, nothing seems to help. Battery drains fairly fast too, once I manage to get it to 100% it shows that expected time is like 2-3hrs if screen on. Thanks!

battery displaying different percentage after u remove it and put it back in is normal i have 3 note4s all do the same (up to 10 percentage change, it either increases or decreases) but the other issues like getting stuck on a certain percentage are not normal make sure u have the genuine battery and try stock rom.
yeah, i tried stock and the same thing really. such a random issue. I just noticed that battery charges once I turn the screen on and use it , so it only gets stuck on random percent only with screen off.

once the battery is charged to 100% it also drops first 10-20% really fast and then it gets better but still I only get around 2hrs screen time

Oops my bad..Didn't read your whole post...
the only way to fix this replace your battery by new one
i tried all options (Format ROM - Wipe battery status - Getting back to stock ROM - Unroot - re Celebrate apps - Changing recovery-Removing battery from device for while sleeping - charge without fast charge - charge via USB)
i asked myself after that all of this headache doesn't worth 20$, i replaced the battery with new one and its working fine now

yeah, i replaced battery as well but it's still the same issue. old one at least charged fully but would randomly reboot on me, the new one doesn't reboot but drains extra fast and doesn't always charge fully. can't believe both batteries are faulty
I am sorry for summoning this old post but did you find any solution to your problem? I have exactly the same experience with my note 4.
Thanks!
Is there a solution for this problem?
Power down and then out-and-in same battery and my stuck-at78%... was 100% when started.
if you having problems with auto restarting.... download the app " WAKE LOCK" and put it on Partial Wake Lock setting... your restarts will be a thing of the past.
