Bought the $35 Chichitec batteries (2) and charger off Amazon for $35. They have a good rating and I needed some spares. On the first discharge, I was down to about 40% and decided to restart my phone using hold-power, restart, normal. I was running CleanROM 2.9.5 which I had been on for about two weeks without issue. This time when I restarted, the phone soft-bricked on boot with the screen blank but I could still see the faint backlight on. I gave it the three finger salute (virtual battery pull) and it restarted and looked OK... until I started to use it. Literally everything I tried including internet, camera, messages, people... all FC. I restarted again. Same thing. Everything forced closed as soon as I started it plus some of the auto-start stuff forced closed while booting.
Next I did a physical battery pull and left the battery out for about 10 minutes. No change. Still NFG. So then I decided, no problem, I have a pretty recent Nandroid backup so I'll just restore. Booted into recovery no problem, went to Nandroid, recovered the backup: all messages said backup has been recovered and no errors. Rebooted the phone and the Nandroid backup didn't even work! It was as if it did nothing! I could tell that nothing had changed. Even after the Nandroid, the phone still had apps, SMS messages, etc. from that same day even though the Nandroid was from 2 weeks earlier. Not only that, the FC's were still there and the phone was basically still "soft bricked" because you couldn't do anything with it even though the home screen looked "normal". As soon as you touched anything, FC's out the wazoo.
I started thinking about what changed and what might have happened and ended up on the Chichitec battery: first time I've used it. I plugged the phone into AC power, did a normal restart with the phone plugged into AC power and guess what? It booted and acted normally! I charged the battery all the way back up and because I didn't know what state the phone was in, I did a full wipe and install of the latest CleanROM DE 2.0. Been fine ever since.
So my thought/question is... could something with this Chichitec battery have caused this? I thought about undervoltage but if it was that, wouldn't the battery meter be reading low? Or maybe it was a low voltage transient that is quick, caused by the battery dropping too much voltage when under high demand? I know the battery draws a full amp during boot, so maybe during high draw periods like that, the battery's voltage dropped too low and caused the CPU to take a dump. Weird thing is, it kept doing it until I plugged the charger in, at which point it cleared up immediately. It does seem to be a power problem and a pretty serious one if Nandroid can be run, appear to work normally, but in fact the Nandroid did nothing???!!!
WTF is going on? Anyone experienced anything similar?

I've been using them since shortly after launch and haven't had any issues. Something may have just gotten corrupted when you did the reset, I don't think the battery itself would be able to cause something like that.
Yeah I have two chichitec batteries and I have no problems with them either.
I've been using 2 chichitech batteries for a while. My only problem is that they seem to lose more battery while screen is off than normal batteries. My phone is probably awake 10-25% of the time of screen is off and with stock batteries, I will lose 2-5% overnight. With the chichitech, I lose around 10-25%. Other than that, they preform better during normal usage.
But yeah, your issue is pretty strange. I'll remember this incase I get the same problem.
I think it was most likely a corrupt sd card. I've has it happen to me with similar symptoms.

Hmm I haven't had your issue either....what I do like is the chichitec batteries fit a tighter in the battery slot than the stock batteries.

Yeah, the stock battery could have packed some more power with that extra lost space.
I have chichitec, and fortunately haven't had the same problem, but the battery life wore out pretty fast, when I sent them an email about it I got a coupon code for 10% off my next purchase. That's all they replied with. Haha, good luck with ChiChi.

I've read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?

I am curious of this was an isolated incident, my phone started shutting off on me even though it had 20% battery left. No warning. Sometimes it would turn off at 40%. It would also not charge. When the phone would be plugged into the charger, it would get HOT. Later though, the phone would get HOT regardless if it was plugged into the charger or not. Also had issues with the blue tooth but that could of been a software issue. It would connect to my car's radio but could not play music through it, I would have to shut the phone off and then turn it back on.
I got my new phone in, already S-Off it and its up and running good with Quicksense.
Anyone ever had this issue?

Same thing I was thinking...
Ah yes I forgot to mention, I used 3 different batteries, same thing happened to all 3. HTC neglected to ship me a battery, so I am using the 3 batteries I have. Primarily I use Anker 1900mah
Batteries works fine on my new HTC Amaze. As soon as I would use the battery on the broken phone, it would get instantly hot. Doesn't happen on my new phone. Standard life for my battery was between 12 to 16 hours depending on how I use the phone. With the defective phone, it would get hot and within 3 hours it was dead, couldn't even charge it as the phone would give me an error saying it's not getting enough juice. It was fine last week, this started happening a few days ago.

I have a similar problem with my Anker 1900s. They go down normally to about 25%, then basically drop to almost zero in a couple of minutes. I have no problems with the stock battery.
I've had (might still have) a problem with the stock battery shutting down the phone at random % (even at 90), then restarting with a much lower one. Sometimes it would not even want to turn on. I'm currently using my chichitec 1900mAh battery, and it seems to be ok. Will be calling HTC to get a new stock battery, once I can confirm that it is, indeed, the cause for all this.

I ruled out the batteries, unless all 3 can go bad all at once and cause the phone to heat up. Those same battery are in my new phone, no issues.
Check the battery contacts on the device itself...something may be bridging them or something along that line.
This is crazy. Did you check to see if the contacts are clean? And also check the USB port to see if anything has moved or lodged inside. I would recommend an air can to get the tight spots.

I'm having the same problem too were the phone is shutting it's self off. Usually after a reboot the batt level has dropped quite a lot. Sometimes it goes right down to zero. You can see in the screen shots were suddenly there is a huge drop in batt levels, you can even see where it goes to zero.
At first I thought it was just the Rom i installed (xboarder's) but i've flashed ICS Speed Rom and having the same problem.
I have noticed almost every single shutdown has happened at work where I get a very poor radio reception, almost as if this if causing the shutdowns..
Maybe 2 problems at the same time combining to make it worse. Some days I can get 6 or 7 shutdowns at work.

And I am having the problem with aftermarket batteries, but not OEM!
Sudden drop offs like this are characteristic of a failing battery.
Check this out boys and girls. Approximately 2 months ago I got a new stock battery to replace the original that was causing reboots, which then showed the battery level at 0.
Started using the new battery and the same thing started last week. Reboot, low battery even when it was recently fully charged.
So I put the original in which hadn't been used in 2 months. Blast a full charge, wipe stats. And sure as ****, it works fine.
I almost wonder if it sitting for a spell and not being charged "refreshes" or replenished the life?
I'll keep you updated but thought it was weird.

There's something definitely fishy with the amaze. I had 2 of them, and I'd swap batteries with different charges, say one had 80% and one had 40%. After swapping the one amaze would read close to what the other did, within a couple percent, and the other one was way off, like 30% higher, and it would die way before reaching zero. Funny thing it was only the one that did that with a battery swap, so the amaze is just weird when it comes to reading the battery charge.

It's not jstu the stats Nelly. It's the overall performance and the intermittent shut offs. Since putting the "old" battery back in I can report that after 1 week I have had zero shut offs. Battery is giving me about 7 hours on heavy usage.
Cant figure it out.
Definitely leaves me scratching my head at times.
I just started having a similar issue.
For example, I would be checking my email, or checking facebook, then BAM! Phone reboots/shuts off. The battery icon says I have 47% but in ext4 i have 85%. Wipe battery stats in ext4, works fine for like 30min. Same **** starts again.

Have you contacted HTC. Call HTC direct and explain the issue. Ask them to send you a replacement battery. Stay calm, nice and let them know you need a new battery. They will ask you for a credit card to put on file and will tell you to return the old battery. If you dont have a cc ask them to speak with a suprevisor. They can waive the CC requirement if you are polite and don't get into a shouting match. As far as my battery, i am back to my original and it seems to be doing good still. I did have one reboot last week. But that's about it.

Well, you can stop wiping battery stats as a step, since it does nothing.. tons of info out there to show this is 100% fact https://www.google.com/search?q=wiping+battery+stats+does+nothing
If the engineer who helped design android isn't a good source, not sure who is.
As for the accuracy of reading the battery, pretty sure everyone has this issue.. someone recently posted something about the sensor being low quality, but who knows.
Apart from having reboots(which is an issue likely unrelated to battery except for maybe the OP), if you know your battery has 20%, but after a reboot it says you have more/less.. why does this matter, you know you have 20% worth of life left.
As for the OP, you may want to try flashing the stock RUU as there may be a serious problem with your system files, and flashing the RUU in the bootloader is the quickest way to know that EVERYTHING has flashed properly. Instructions in the bible in my signature.

It matters to me. A few times the battery icon/widget says 0 and the phone shuts off. I use the Vol and Power to get into recovery, and it says 20% or whatever it may be. Sure, I know it has 20%, but the OS detects it at 0 and shuts off.
I just remembered, a day or two before my initial post, my battery became super hot. I remember this because, I had the phone in my pocket, and it got really hot. Battery monitor widget reported the temp at 129 deg F. I guess the battery is shot.

Been testing out the batteries extensively. OC'ing, flashing roms, backing and restoring in ext4, netflix, games, and LOTS of data lol. No random shutoffs as of yet.
I'm on Bulletproof 2.5 and after unplugging my Amaze, it stays at 100% (or whatever % i unplugged it at) for 10-30 minutes then my battery goes down by 2% increments and sometimes it hangs around at a random % for about 15 minutes and then continues its 2% increments again. Does any one have a similar issue? Is there a fix since wiping battstats does nothing.

Me and my wife have both an amaze. Her phone started to do the same thing and a couple of weeks after hers mine started. Since I'm an electronic technician I knew there has to be a problem with the connection on the battery. After inspecting the batteries I noticed that the four connections on both batteries had deep marks on them. To fix them, I used a small flat screwdriver and using the flat side scratched the four connections until the deep marks where mostly gone. It's been 3 months since I did that on both batteries and the problem hasn't come back. FYI the two connections on both ends are the + and - and the ones in the center are used for reading the battery status. Hope this help those with this annoying problem.

haven't used stock in a long time, but is there an option to turn wifi off when the tablet goes to sleep? ur wifi might be sucking up power continuously if it doesn't shut off.
Yes, that is correct, Wifi can be switch off. And I have done that. But the drain has become very significant.
I am considering going for a warranty repair, but my guess I will get a refurb with another weak battery, and hassled because I have rooted and blocked OTA.
Are most folks just running off their chargers?
If folks have bad batteries are they replacing them themselves?

you can attempt to request for a new nook tablet placement. After two refurbished replacements with the same problem as my original NT. they sent me a new Nook Tablet and so far so good. It's worth a shot.
Came off the island today and went to the big green city. Stopped at BN and did some talking with them and also to the service center at the same time. The service center said they would send me a refurb. My 3-4hour of run time is way under the 11.5 hours you should get for the e-reader mode only. That fella felt like the battery developes memory and needed to be fully discarded to combat that occurring. I can not find any technical document that supports this idea. There are not NiCad batteries.
Anyway if I send my tablet in I will end up with 1.4.3 instead of 1.4.0.
When you get your replacement
Once you get your replacement, it's a good idea not to charge it until it show very low percentage on any nicad rechargeable batteries. When you charge it, don't remove it from the charger until it reaches 100%. Also don't have a habit of plugin it in when finish using it, plan ahead so that you can have a fully discharge battery before recharging. Your NT battery charge will hold a lot longer threw time if you do it this way. You also can try this app to see if it works.

Good advise, thanks,
I put in some effort to side load the battery stats reset software and found a application call: Battery HD. I loaded this app instead. It provides a graph of the charge and discharge rate. From the graph I can see that my battery is OK. I became aware of some funnies going on when I woke up at 3 am and saw the display on. With the discharge rate as specified I now believe I have some application causing me trouble. I don't have much on the table, Titanium, MX video, Amazon apps.
I shut the unit off last night and it came back right to the same charge. Tonight I will leave it on and check the graph to see if there was an load and when. The application has a gross report on the power used separated by function instead of application. It also has a calibration test that tests the three main functions and reports the discharge rate.
Anyway, I will post what the nightly current hog is if I can find it.

My friends NT has been having issue with screen turning on by itself. Seemed to narrow it down to aldiko app. Not sure why it's happening. Performed a clean install of CM7 and issue came back. I keep thinking it's hardware related, trying to convince him to try a different ROM, but he's stuck on using CM7. If you find a reason for your tablet screen turning on let us know so maybe I can help him get his issue resolved. Thanks...

Once you get your replacement, it's a good idea not to charge it until it show very low percentage on any nicad rechargeable batteries. When you charge it, don't remove it from the charger until it reaches 100%. Also don't have a habit of plugin it in when finish using it, plan ahead so that you can have a fully discharge battery before recharging. Your NT battery charge will hold a lot longer threw time if you do it this way. You also can try this app to see if it works.

That's actually bad advice for any lithium based battery - like the NT's lithium ion battery. LiON batteries don't like to be fully discharged and they don't like heat, especially heat when they are fully charged. That means avoid full discharges and avoid charging it to full every time, and do charge the battery more frequently (keeping the charge level between 20% and 80% for example). Partial discharge on LiON is just fine; they don't suffer memory effect.

I have said it in past post, I need glasses. I totally missed this part while reading "There are not NiCad batteries" the word not always gets me.Sorry about that sgschwend. I did not even know, thanks for the info update.
Well, I always appreciate advice, my view is that it becomes a starting point and it is up to the reader to combine it with a working course of action.
As to phantom startup/turnons I checked last night and there wasn't one. I will continue till I find it. The summary screen does say what type of application is turning on so that should help. The only gotcha will be if the battery application changes how the tablet works to the point that the issue will not occur. I don't think this is very likely.
The battery application (battery HD) makes a nice graph so you can look at the slope and see what is going on, it also lists the run time for various activities based on the current battery charge. Interesting to note the Nook charger overcharges a bit and the battery does warm up some. When it cools down the charge is just under 100%. This is not an ideal situation, it would be better for the charger to slow to a point that the battery temperature is not elevated near the end of its cycle. Splitting hairs perhaps. My discharge rate matches the tablets specs even with the battery application running.
Second day of monitoring the device operated correctly. I did check and found that I have a Titanium backup batch job setup to run every day a 3 am. Which coincides with time I observed the device display turning on. I will move the time and see if the issue moves too.

Also turn off push notifications that certain apps have. They suck up a lot of battery. Install the Better Battery Stats app (search xda for it). Won't have to pay unless you want to. Monitor the partial wake locks to determine what apps are using battery during sleep.
I have a similar problem, i got a nook with cm7 and the battery doesn't last at all, i charged it yesterday and let it all night without touching it to see how long would it last and after 12 hours i got 30% and it says 70% of the battery was drained by the andoid os, it says that the processor was working for 2hrs!
i got it and stared looking for an answer to this problem and in less than 10 min it has drained 4% of the total charge, this didn't happened with the stock firmware so I'm thinking about trying jelly bean and if it doesn't get better i will have to go back to the stock firmware
Hwong, I think you hit it on the head. Last evening my NookT had a much higher current draw, loosing 20% in 12 hours. I saw this when I checked it a midnight. I had left the Nook with the battery monitor application in the graph mode, likely running as an active application instead of a "monitor" mode. Titanium Backup did run last night but it runs for such a short period it did not even show up on the graph.
So I really don't know which application or notification is causing me a problem but the issue I have had is like loosing 20% of my battery in a 6-8 hour period. Which to me looks like an application is running that shouldn't and the time I observed the screen on would do it too. As I started this post I am still on 1.4.0, rooted, OTA blocked with hidden commands.
I did a hard factory reset and wipped the caché, now my nook has been charged for 2 days on sleep mode with the wifi on.
I believe the problem was caused by an application, i believe it was the launcher and theme i was used, i re-installed it yesterday and the tablet started to drain battery quickly again so i cleaned the data used by them and uninstalled them.
The battery monitor widget use to say my battery would last 2 hrs of video playing, now it says it should last 8:30, closer to the 9hrs promissed by B&N.
It all about old sins. I found that I was jumping around in the normal Nook UI and not using the back button. So several things were still running in the background. Even though that little darling looks the same, that background stuff is a killer. I did a quick test with the battery monitor by leaving it in the graphic mode and sure enough the discharge rate went up 400%, just a dumb graph in the background plotting Voltage versus time. When I use the back button on the application graph, the current draws goes to near zero.
It really does a nice job of standby or sleep.
Maybe this will help.
You could use titanium backup to freeze the apps that you think could be causing more than usual battery drain and maybe narrow the issue down?:fingers-crossed:

Well I had hoped that this day wouldn't come,
But.... My TrueSmart has stopped working.
Not sure what the issue is..... I went to turn it on this morning like I always do... (I turn it off at night).
Pushed the "on" button and got no response from the watch. So I pulled the battery, put it back in, watch will flash white for a few sec and then be dead.
I swapped in the other battery I have... same thing.... So I thought that somehow the batteries drained themselves... so I connect it to charge and there is NO indication that it is charging... Left it for a while to see if it would come alive...
Nothing.
Very disappointing.
I was actually enjoying the watch very much looking forward to what the Devs were coming up with next. Pretty bummed out.
I guess I will put it in a drawer and one day when Laurent Le Pen opens a repair center I might be able to get it fixed.
Back to wearing my Pebble I guess.
Such a shame.... it was a nice piece of tech that started many conversations when people saw it.
D.
I would not give up and still try to revive it. If the battery it's very low it will take some time and several tries before the watch will show signs of life. And the connectors of the dock may not be perfectly working, or even the cable may be faulty. I find it hard to think that the watch just stopped working out of nowhere.
If the battery drops below a certain level the watch will never charge it. The part of the firmware that is supposed to prevent this........doesn't work. The only option is to use an external charger but there may be a fire risk.
The battery situation sounds like it may be accurate as I did drain the battery the other day.
So if my only way to try and get a charge into the battery is to remove it and put it in a stand alone charger, what charger should I use?
D.
That's the problem most likely.
What Loki said is true, many users reported that and even XDA review said same.
It would be great if someone knows for a external charger on ebay we buy and use if that happens.
Even there's a way to charge battery with a stripped wires on usb charger - that's something you shouldn't do if you don't know what are you doing...

What battery level percentage is this? I've used mine down to about 10% and it's recharged fine before.
I think you have to let it run right out.

Well...probably ~ 0%.
The trick is to never let TS turn off by itself because of the battery level is too low...

I have let my TS run out by itself several times already, and it charges fine even after that. But it's noted that this is a bad idea..
Anyway, the batteries that came with my watch was about 70% charged from the box, so it sounds unlikely that the other battery that OP tried is completely drained as well. My guess is that there is something else wrong with the watch.

I use my TS without cell signal and I've found if I turn off the device and don't use it for a while then power it back on the clock and date will be out of sync until you turn on a data connection. This leads me to suspect it draws no power from the battery to retain these settings when the device is off, which would make sense about why it has this issue? I know for sure Samsung phones etc they display the battery percentage without the reserve to prevent such an issue happening on their devices. As Loki mentioned broken firmware maybe something could be written to prevent this or even to just show the percentage differently.
The time/date issue is because they removed the back up battery (to save space) that keeps the time on all normal sized phones.

My galaxy note tablet has this problem.... it runs down fast and then just looses all date and time lol...
I think the issue is my batteries....
I was doing some experimenting today and with some fiddling around I got the watch to respond....
Battery #1 was 8% and then in about 2 min of being connected to the charger was reporting 55%
Battery #2 won't even do anything....
So, I am convinced that the issue is the batteries and not the watch.
Laurent has contacted me and provided a way to get my watch replaced, but it will require me to send it back and then wait for a replacement to be sent
Rather than going through all of this just yet, I wanted to see if I could solve it first.
So, if I wanted to get a replacement battery on my own, any ideas where I could get one from?
D.
no idea. maybe see if anyone near your area also had a TS and is willing to loan you a spare battery for a beer? haha

watchdog service that prevents the battery from draining completely does not work on any of the firmware that Dees, Adam myself and other tested. So even if the battery is the best battery in the universe, an Omate can kill it. I even went so far as to test it with a Motorola battery and it killed that too.
Yeah. It looks like the batteries are toast.
I managed to get one to charge to 100% and was able to use the watch for about 30 min then it died. No signs of life and can't get it to charge again.
I really wish I could source a replacement battery to make sure it is the battery and not the watch so I don't waste the time and money sending it back.
The shipping cost to mail it back is crazy from Canada.

"Omate - something new..."

We should get them to tell us a model number so we can source OEM's. What's the motorola battery model Loki tried with his?
Mines run down completely a number of times without issue but I think I'll have Tasker cut it at 5% from now on.
