Anyone else with this problem...?

Hello all,
I bought the HD a couple of months after it first was released and have never had this problem until about 3 days ago, where my phone has started to suddenly "die" even with ample battery life in it. When I reboot it, it simply starts to reboot then dies again as if the battery is dead, however, when I plug it into the charger, it shows that it has over half to almost full battery life. So the problem can not be that the battery is simply dying. What could be causing this problem? I have ample free main storage and program memory and it occurs even when there is only one program running or even when I'm just in the middle of a call.
Can anyone help me solve this problem? I have tons of medical programs in my phone which took forever to install and don't want to hard reset the phone, especially if that is not even the solution to the problem. Help?

Same thing happened to me, but my phone gets some water. I had to dry it and wait a month. Then it worked fine. If your phone hasn't took any water the problem must be elsewhere.
One question, it dies even if attached to the power? or only on battery?
If it dies only on battery then could be the battery not working properly.
bye

Batteries do weird stuff when they're dead. If it works OK on power but not on battery, chances are the battery is indeed on its way out. If you don't want to do a hard reset, a replacement battery on ebay is cheap and worth trying.

Hello,
I have exactly the same behavior. I changed of Rom, different build, each time running Task29, but it is always the same thing :
- when charged, phone never dies
- when on battery, it randomly dies but always when phone is awake
I think too it may come from the battery, so I just ordered a new one, and I'll keep you up to date.
Ciao,

Yea, so far it has occurred about 4 times, always when it's not plugged in however the battery meter shows alof of battery time left. I'm thinking it's the battery too, it just sucks to have to pay so much for an OEM battery. Oh well, thanks for the help everyone.

Hello,
so I received my new battery this morning.
After some phone calls and some tests...so far so good ! I'll tell you if something's change in the next days, but it seems changing the battery is the solution.
Cheers,

Mine started doing similar things. Guess I will order a battery too. Which one did you get?

Well I got the exact same one I had previously : an official htc touch hd battery.
Part number : 35H00120-01M.
I hope this one will last until I really want to change my phone .

Any more issues since replacing the battery?

still no issues so far. I am really happy because as the battery is new, my phone last much longer than before.

Same here. Got the new battery yesterday and it's back to it's old self. Now it should last me until the dual core processor Android devices come out next year.

Well it would be nice if my pnone only turned off when it wasnt on charge but it seems to just reset itself whenever it wants. it will simply turn off and start right back up sometimes not even reaching the rom load before it turns off again. It does this for a while or just simply once. I tried erasing all data off it and hoping it was something i uploaded but it could be that my battery is just no good anymore.
Any suggestions? ive been dealing with this for 6 months

I don't know about you, but I played quite a lot with my phone, trying a lot of ROM, for a while, even beta ones, and I tried to overclock it. Often the phone would heat up a lot. It may have be hard on the battery.
Right now I am using a stable rom of NRG from last month, with the new battery, and everything is fine. The phone never heat, and I happy for now.
Like Marksm, I am waiting for Android dual core phones or at least based on Tegra 2.

As pointed out in above posts, a change in battery appears to have rectified issue

been there done that. Didnt work, i got a new phone but i would really like to keep this.

[Q] [Help] My battery is draining too fast, some soft problem ?

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!

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.

[Q] How can I test if battery is bad or phone isn't charging properly?

Does anyone have any suggestions on what I can do to test which one might be bad? Any app you know of that can monitor things and tell me if a rogue app is killing the battery or if the battery is bad?
I was running mik 1.1 and was using it pretty heavily with gaming and downloading stuff. The phone died after about 7 hours. I thought that maybe the rom or cwm or something else might be killing the battery. Something strange though is that, like I said, I ran the battery until the phone shut off. Then I left it off and put it in a wall wart charger for about 8 hours and the status light was still orange. My gf had the phone and told me once she left it plugged in overnight and in the morning it was only at like 50 something percent. I thought maybe the charger went bad so I gave her another one and she didn't say anything else about it. I'm starting to wonder if maybe the phone's battery has a weak or bad cell. I kinda doubt that there's something wrong with the charging circuitry of the phone but there could be, anything is possible. I will probably take it to the repair center and tell them about it and see what they say. I tried looking on htc's site for oem replacement batteries but couldn't find anything. I found lots of aftermarket but I didn't want to go that route.
I don't know if it would not be a good idea or not to try and use my original evo battery just flipped over. I suppose if that's the only thing I have to try and troubleshoot this problem then it will have to do.
Can anyone give me suggestions or has something similar happened to you?
Now let me see if I can find that evo battery..........

Spare parts, in the market if not on your rom by default, had a battery information tab that will indicate battery health as well as what kind of plug the phone detects when charging (usb, ac, or none)
Sent from my PG06100 using XDA App

Like danaff37 said, spare parts can be useful. Also try CPU Spy, free from the market, which shows what % of the time your CPU spends at each frequency, but this actually more relevant for determining if your phone is properly sleeping..
For proper charging you can get an app like CurrentWidget or Battery Monitor Widget which tells your the current consumed during usage or current injected during charging, as well as the voltage in mV. Full charge should reach around 4200 mV, and when charging the current should be around ~800 mA for lower % battery left.

Thanks for your input. I found the evo battery and did the same thing as before. I ran it until the phone shut off and then put it one the (same) charger and went to bed. About seven hours later, it was still orange charging. Both times the phone was off. Now something that could be a possibility is the charger is weak or bad. When I put my evo on it, it charges seemingly fine. I should try using the battery until it shuts off again and use a different charger and see what happens. Six to eight hours charging, with the phone off, coming from a dead battery, on a Motorola charger that has a rated output of eight hundred milliamps at five volts. I have others at different output rates and a two amp charger intended for an ipad. Some might say that the charger is too much for the phone. The charging circuitry only pulls as much amperage from the charger as the phone was designed to. Now on the other hand if I put a smaller output charger on, say one hundred and fifty milliamps, it will take longer to charge the phone than usual. "They" say trickle charging is better. Whatever. I will post my results if I find any. Or, I just might trade the phone in for a nexus s or an evo 3d.

I was just about ready to throw in the towel and say the phone was defective, but then things started happening. I will fill you in on what I have done in the meantime. Okay so the flipped over evo battery kinda works but not completely. It will charge but not to 100% and green light. To test this, I took the evo battery out of the shift. It didn't seem to want to go more than 98 or 99%. I put the battery into the evo and after a few minutes the light went green. This was initially off. Then I booted the evo and let it go to sleep. After it booted the light went orange then green after a few minutes. Okay so the evo battery is capable of going to 100%. These charging tests were done with a different charger.
I forgot to tell you, I let the evo battery charge while I was at work and the phone was off. So the battery was charging roughly twenty hours and still no green light. I suspect that even though the positive and negative terminals aligned with the correct tabs on the shift, the center two contacts must be different internally than the shift battery. I speculate that those center tabs are for the battery and phone to communicate to each other during it's charging state. I am guessing that the battery tells the phone it is fully charged and to go trickle charge and perhaps the evo battery wasn't communicating to the phone or the phone didn't know when to say it is done charging. The battery never got hot either.
The shift was rooted, running mikshift 1.1 and the latest clockworkmod recovery. Here is where I suspect that there still might be charging bugs with that setup. I used the pcxx.zip file that when booting into the bootloader, would flash the phone back to stock everything. After trying this and assuming that the phone was back to stock, I kept going with my what the hell is going on with this phone battery charging test. A note about the flipped evo battery. Yes it will work in a pinch but it won't charge properly. Luck has it that the notches in the battery and phone allow it to work in a shift. Only thing is, the shift battery won't work in the evo. The tabs are on the wrong side and the phone's tabs won't allow the contacts on the battery to meet up with the phone's terminals.
Okay, where was I? Trying different chargers wouldn't make the shift green light full charge. I tried the same chargers on the evo with it's original battery in and it would green light after a few minutes on or off. There wasn't anything wrong with the chargers. Oh and another note, while using the battery monitor widget, I noticed that both phones wouldn't pull more than a little over three hundred milliamps of power from the charger to the battery. Interesting to know how much it really pulls from the charger.
Anywho, I tried something different for my process of elimination testing. I actually ruu flashed the shift back to factory and guess what happened..... The battery and phone were charging both on and off all the way to green full charge at 100%! I think I'm getting somewhere with this! All my luck, either it is a known bug somewhere in the forum in a place I haven't stumbled across or I'm the only one that this is happening to. It doesn't really matter I guess.
My conclusion, which isn't scientific by any stretch of the imagination, is that the phone isn't truely back to factory unless you ruu it. The pcxximg.zip doesn't put everything back to stock. I haven't narrowed it down to what is causing this behavior. I don't think it is root. It could be cwm recovery or the rom or both. I didn't try the stock rooted zip either. I suppose I could go further with this investigation but I am too lazy to now. I might root it again and just leave things stock rooted. I might activate this phone in the morning and run it all day tomorrow and see how it acts. I will have to charge it a few times during the day to keep the levels up when I really use the phone heavily. I've written enough for now. Does anyone have anything to ask or add to this topic?

Since the latest update to CWM phone-off charging finally works again but the light never turns green. It charges fully but with the phone off the LED never turns green. It's not just you.

^ Shift Faced

OK. I thought something might have been broken.

Forgive me, I am truly a newbie to Android after having a BB for 8 years. This battery thing is killing me. I am on my 2nd Evo Shift, the 1st one wouldn't last for more than 2 hours with barely any usage so they gave me a new one. This one barely lasts 5 hours. I am barely running anything. I took it into the store and they thought I was going to be running all these programs, but I kill everything. They told me the "battery trick" about turning off the phone and unplugging it and plugging it back in 10 times so I did that but I am not getting any more life out of the battery. My display is constantly using at least 70% of the battery it says even if I turn it down very low or if I set it to choose its setting. Do you have any advice for me? I am not running a task killer, I kill all the programs I am not using. I have no widgets running because I am afraid to use the battery, I only have 2 screens out of the 7 with things on them. I am being help hostage by my cool phone that I want to use but am scared to kill the battery! (sorry for the long post)

Ok if you use a lot apps just close them after (for stock 2.2) . Even on stock you can literally stream music and movies for about 4-6 hours. (sometimes a lot more) . The background info that runs doesn't use a lot of juice , but if you want you can go to your home screen any of them hit menu (but not with the app drawer open) select settings go to accounts and sync turn off background info and just turn it on manually when needed such as the android market . You can also turn off the auto sync and just manually choose to sync , like in the clock (and gmail etc.) it will say no weather after you click it , just hit menu you will see a little sync button option to sync and voila you have weather . So when you visit the market it will automatically ask you to turn it on (background info as will all apps that need this) . And the screen on any android is a battery killer . So when not using your phone simply tapp your power button to turn your screen off and lock (and to keep from pocket dialing lol) . But if all you do is text , emails , and web surfing (surfing drains more but no where near as much as streaming) you can literally do that all day , the screen will actually suck the most power . If manually turning off your apps is too much . Just turn your phone off (not just the screen) and on . If a new app didn't turn off after you start your phone back up you know that will be a problem later . So when not using your phone turn off your screen it will last soooo much longer . I only make a call or two and a couple of texts maybe a few minutes of internet with opera mini . My battery lasts over 24 hrs , but I barely use my phone . Hope that helps .

BTW if you have a bunch of apps running in the background video games etc ... and you charge your phone all night and in the morning it is not charged . You should probably turn your apps off . Or simply power your phone off which shuts off most apps . Then turn it back on . The phone should not take all night to charge , it should only take an hour or 2 . 3 hours max .

i suggest watchdog lite,it monitors cpu usage and alerts you when 1 uses more than your max threshold.if this helps,please click thanks.

When you changed ROMs, did you do it with a full charge? If not, your battery stats file is probably messed up.. Ive used Battery Calibrator free from the market in the past to fix that problem.. I believe a brand new battery on the Shift shows about 4200mV when fully charged or just slightly below that.. Run the app, when it gets close, calibrate (which essentially just deletes the battery stats file and creates a new one)

Power related issue

I'm finding that sometimes when I plug in the tablet to charge even if they battery is almost full, as soon as I plug it in it will think the battery is at 0% and start shutting down.
When I power it on and look at the battery stats it shows that the battery went to zero and then goes back up to were it was before the shutdown.
Also another issue is that the battery status will say its not charging even though it's not plugged in and the level never goes down even after a reboot. I find to fix it I need to go into a custom recovery and reset the battery stats for it to return to normal for a few hours.
I'm running on the stock image.
Its annoying, but I'm hoping that the next update will fix this.

Can't say I've ever experienced such an issue, on any device. If your looking for a fix, perhaps reflashing the factory image completely might help (I don't understand the battery stats file too much, but I would think a reflash would probably replace that file, and fix the problem).

I thought I was the only one with these problems. Never had these issues on my Galaxy Nexus. Now on the N10 I have the first problem you mentioned + battery % not moving until I reboot the unit (Random). Very annoying...I called Google Play support and after doing some test told me that they'll send my a new unit.
Note: I've flashed the Google image and I still had the issue (seems less frequent)...Sometimes I can have the % correctly refreshed and sometimes it stops after a few minutes.
I've attached screenshots of the problems...(1st image) Long straight lines were when I was actually using the device!! Cut in graph = reboot
Second image: both problems, check out the spike a 0%!! when plugging usb cable

I have the same issue and my replacement is on it's way.

So I called support and I'm getting a replacement device.

I've been searching everywhere, thanks to this thread now I know I'm not the only one having these exact same issues. Looks like I'll be making a call to Google Support

Probably a software issue to be addressed in a later update.

Are these issues still present on the replacement devices?

So far not happened on my replacement device. Went from 70% to almost 10%. Still testing. Also wakeup time is normal. I think it was hardware related.
EDIT: on my 3rd day and this new device always correctly reports battery life. Definitely hardware.

I'm having the exact same issue with battery % not updating at random times and then sometimes the n10 claims 0% battery after recharging overnight and promptly turns itself off. Did the replacement unit fix this for you?

I got my replacement unit 4 days ago and the problem is definitely gone! On my first device it also happened since day one.

My Nexus 10 just started doing this after a reboot last night, I guess I'll have to ring support and get a replacement.
I'm running a custom kernel, recovery and unlocked bootloader. Do I have to flash back to complete stock before I send it in?
Cheers guys

I'm not sure if I have this issue, but my N10 is definitely acting strange.. I put it in my bag this morning on 42% charge and when I took it out in the afternoon it was dead (I thought I might have hit it to something and damaged it), but when I plugged it in it started to charge after a few minutes from 0%. Then it rebooted after like 5 minutes without me touching it and it's charging for now. The battery stats don't show a drop to 0%, the graph ends at 42..
I've had this device for around 3 months now and never encountered this issue before, so I'm not sure if it's really a hardware issue, but I'd be quite disappointed if I had to get a replacement as this one is a really good one in terms of the other common issues (bleed, throttling, creak).

Hello xda-developers!
I have this problem which have bothered me the past couple of days. Basically, yesterday, 18.11.2013. i played Dead Trigger 2 (game, not that processing power hungry, but still). My phone gives me notification every time when my battery level reaches 15%. Since August (when i bought this phone) i could use it, play games etc. ignoring the notification even till 2% was left, but yesterday, when i reached 15%, the phone automatically turned itself off and to turn it on again, i needed to connect it to a charger. And when i turned it on it showed me 0% battery. I don't want to believe, that my phone drains 15% in a matter of seconds. I'm really worried about it. Could it be some kind of battery issue or phones? I've been very gentle with all my phones, so this is a big thing to me.
I'm still running Android 4.2.2 because my S4 is rooted and i can't manually update it via the keys or unroot it because S4 doesn't support my old Windows XP SP2.
Looking for a solid answer. Thanks in advance.
P.S. This is my first ever smartphone.

Sounds like a battery issue.
Check it's not swollen in the middle and check the serial number.

Check it's not swollen in the middle and check the serial number.
Batches starting with BD are known to be faulty.

Checked the serial number and it starts exactly with BD. Also, didn't notice if the middle was swollen, looked pretty good.

In that case mate I would just go straight back to the place you purchased it and tell them that you are aware of this batch of batteries being faulty and you would like a replacement
