Lol not sure what happened here.
I left my phone off charge to take a shower at 60%, came out and it was 20%?
Im on MIUI Rom 1.11.11
Is it just bad calibration or something?

Did you also see a significant drop in raw battery voltage?
Most likely the fuel gauge just glitched or reset. 40% in 20 minutes = 2 amperes drain, our device simply can't pull THAT much current, not even close.
Does if really equate to that much? I have seen a few cross ROM battery complaints ND I'm pointing my finger at the Facebook app

Fastest ive had mine drain down is when I left PocketCloud logged into a VNC session. It will run it down close to that fast.
Ya, Id take it off teh charger, reboot and see what it says after that.
When I was running CyanogenMod 7 this would happen all of the time to me. My battery would be at 98% and then suddenly after about 5 min, it would read 50%. I'm not really sure what caused this, but CyanogenMod 7 is the only ROM that I have had this issue with.
I'm now running Miui and I haven't ran across this issue yet.
I did read that calibrating your battery should solve this issue though.
Possibly similar to what a few of us encountered here: http://forum.xda-developers.com/showthread.php?t=1325164
It had to have been pretty hot to draw that much current that quickly. It's a 1650mAh battery. It will provide 1.65A for an hour from fully-charged, until it is discharged. You lost 40% in, say 15 minutes. That's 160% in an hour. Or about a 2.6A rate. Nearly 10 Watts. Sammy spec's a 9 hour talk time rating on 3G. By comparison, this means normal battery usage during a phone call is about 0.18A. Think about how warm the phone gets during a call, and compare that to how warm it'd have to get if you were sucking juice at 14x the normal rate.
If it wasn't really hot, IMO, either there's something wrong with the battery or your issue is "cockpit error".
Minds did the same thing today. I think it was from a old theme I applied.
After the theme was converted my phone started acting funny.
The screen started to lag
Phone got extremely hot without even being touched, just laying on my bed.
Phone kept rebooting
I didn't have any of these issues until I added the theme

I have a similar problem. My phone randomly turns off/restarts. Afterwards, my battery icon turns gray for a few minutes. When it comes back, it drops by ~10-20%.
This actually happened to me before several months back. Last time, I called HTC and they gave me a new battery. That worked for a couple of months, but now it's back. I'm currently working with HTC tech support to get it figured out.

I was, but I recently installed Energy rom. The problem is still there. I'm running my phone in safe mode now and seeing if my phone restarts.
Quite a few people have problems with stock batteries. I encounter the same problems regardless what ROM I'm running. I bought a couple Anker 1900 mAh batteries and will report back.
You need a new battery, but you can try draining the battery all the way down to the point that the device can't even come on, then it charge it over night all the way back up. See if that helps, it tends to help with this battery issue.
Ido I have the same prob but I was thinking how about resetting battery stats in recovery
Sent from my HTC_Amaze_4G using xda premium
I am so relived to hear that I'm not the only one with this problem. Let me tell you guys my experience with up to 3 batteries, various roms, and weeks of googling...
So basically, changing battery do fix the problem; but only temporarily. It can fix the problem for about a couple weeks or months, but the problem will come back anyway. I am on my third battery now and switching between the batteries; so, I am pretty sure that it is only a temporary fix. Cycling between the three battery sometimes is pretty helpful (but again, it is just a temporary fix).
Another way to fix it temporarily that works pretty well for me is to take out the battery, wait for about 5 seconds, and turn on the phone again. It only fix the problem for about a couple days though; so, might as well switch battery if you got another battery.
Another possibility to fix it without playing with the battery, you can try factory reset or install another custom rom. It sometimes helps also, but a pain if you are not the type that likes to try different roms.
Lastly, the better and simpler fix is to reboot to recovery, wipe all caches and dalvik, fix permissions, and reboot again. This can fix the problem (but only temporary).
Out of those four tries, I find that swapping battery or full wipe / install
Custom rom tends to fix the problem for a longer time. I haven't been able to find any permanent fox for the random shutdown yet. But, I hope those information helps for anyone who have the same problem

The draining battery does work. Just turn EVERYTHING on to drain it (brightness, GPS, bluetooth etc.) and watch some videos to drain it down all the way. After this do a mini power cycle (pull battery wait awhile, put it back, then leave it charging for at least 10 hours).
This solved the problem for me

Exactly, worked for me and quite a few others, I've tested it myself when I had bought my second device used, it came with this very issue, I killed what was left of it and let it charge over night, it's been remarkable ever since, but different folks different strokes, the next best thing to do is to change the battery since that solved it for others. And for the record, the oem battery is the best to replace it with since some anker batteries have only made it worse for some.
getting my newly acquired Amaze device in a couple of days and will see if i run into this issue... god hope not lol... if battery issue does occur - will follow thru the full batt drain solution (mentioned above).

I have my stock battery and 2 Ankers. The phone will randomly die with any of the batteries. The battery drain trick seems to work okay, but it certainly isn't a "fix" IMO.
I drained my stock battery last weekend and charged it to 100% on the Anker charger. Worked great down to 10% on Sunday. Charged the phone to 100% on the nightstand, while I slept Sunday night. Phone randomly shutoff at ~25% at work on Monday. Had similar results with the two Anker batteries too.
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.
I already ordered 2 anker batteries w/the wall charger.

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.

Not sure if it is good to let it die. I was told on the gnex that running it till it dies was not good for thag type of battery? Maybe someone with more knowledge can clarify that.

I know this is slightly a different question. My issue is after you flash a new rom it seems the % is not entirely accurate. It will act fine for a while and then when u get to like less then 10% it drops dramatically like it wasnt reading it correctly or just like today I turned the phone off and did a reboot at 96% and when it powered on it was at 92% which is quite a bit of time on the note 2.
How do you get your battery reading accurate again after you have flashed a new rom? This has happened with my Bionic in the past as well. Thanks.

100-90% can vary depending on when you take it off of the charger. Basically, once the battery hits 100% on the charger, it will start slowly discharging itself to avoid damage. Once it get below a certain threshold, it will charge back up to capacity again.
Regarding rebooting, that process is fairly system intensive and it is natural to lose some battery life. In addition, prior to the reboot the OS is calculating a rough estimate of the percentage left partially based on previous use. So for example, if your phone was in deep sleep for hours, then you reboot where the CPU ramps up significantly, the percentage will alter to more accurately reflect the charge left in the battery.
In short, there is never a need to "calibrate" a battery, the OS will sort it out itself even after flashing different ROMs and it can take a couple days for kernels to settle.
Does anyone still condition their batteries whenever flashing new ROMS and such? I remember back when I had the Vibrant when it first came out and I learned about custom ROMs and xda forums, you always had to condition your battery afterwards. This idea still relevant at all for keeping a healthy battery or extending its life cycle?

If you mean charging your phone to 100% and deleting batterystats.bin, that process is pretty useless. The battery stats file is automatically deleted when your phone reaches 100%, and unless you phone is almost dead, just use and charge it normally.
I usually calibrate the battery using battery calibration only after I have went from dead to 100% on the battery on a new ROM. If you have any issues with drainage like I have on Tweaked before, just do it.

I've has GN2 since launch day. Never conditioned the battery once, never had a single battery problem on stock, Cleanrom or Tweaked. This is the first phone in a long time that the battery just works and lasts and lasts without micromanagement.
I've been wondering this since I got this phone. I always saw the battery threads in the charge forum and thought it was weird when I didn't see that here. I've dine it a few times on this phone but I guess now I know that I don't need too.
Sent from my SCH-I605 using Tapatalk 2
I've been using my Note II for a couple of weeks now and I never had to do any conditioning when using anything TouchWiz based. I flashed an AOSP ROM for the first time today, so I'll be keeping an eye out to see the changes.
Also do you guys think its a bad idea to flash ROMs without a fully charged battery?
Sent from my SCH-I605 using Tapatalk 2
I do battery conditioning...it's called letting the battery management system do it's job and not trying to interfere.
And, there is no particular advantage to flashing with a full charge. I actually can't remember the last time I did, and I'm thinking back across 3 phones over two years. The worst you might get is a messed up percentage until you fully charge, but even that is rare.
The only thing I would worry about if flashing while low on battery would be the device dying mid flash.
Other than that I can see no reason not to.
Right on, thanks for the responses guys. Yeah I just been curious about this because before I used to always see people talk about conditioning batteries and wiping battery stats etc.

Pretty sure the main reason you don't want to flash on a low battery is it could run out while it's still flashing. I've flashed at 30% and no ill affects.
People should go here and then make up their own minds rather then try to follow a bunch of mixed information.
