I know there are already a lot of discussions on battery drain and believe me, I have read every single one of them. However, I think mine is slightly different:
When fully charged and using WIFI for 10 minutes, 10% of juice will be used. Listening to MP3 for 1 hour will also use another 10%. Overall, battery life is really bad but the key is it only happened suddenly. It have been very good up till now.
I have tested this on another battery and have exactly the same results so it is not battery related. I have also hard reset the phone and tested the battery with nothing installed and it still drains. A full charge only lasts me like 4 hour of very light use.
I installed Battlog and the power consumption is around 90 which I think is pretty low, but at times, even with this low consumption, I can see the battery usage literally falling before my eyes, like 5 % in 5 minutes.
I have also tried the HTC battery test, i.e. fully charged the battery, turned on plane mode and full brightness. After one hour, it only used 8% which I thought is normal. However, if I start using the phone by just simply clicking around, it will start dropping.
I believe the phone is fine on standby but once it starts doing things, even simple operations like moving around folders, it starts consuming a lot of power.
This all happens after an overnight charging episode when I noticed that the light stays amber in the morning and the percentage stays at 80%. I soft reset the phone and it immediately show 100%. This has never happen again but my battery usage is never normal since.
All in all, I think it is somehow hardware related, like the battery gauge is bad or the charging is never complete but it still shows green. It is still under warranty but I think will be very difficult to convince the service centre that there is something genuinely wrong with the phone.
P.S. Should also mentioned that I am using the stock telstra rom and have also cycled through the batteries twice before testing.
I had the same problem...
You should try resetting you battery:
1: let your battery drain to 0%
2: fully charge your battery while keeping your phone off!
this solved the problem for me..

I had actually "reset" the battery but only drain it to 5% before recharging as I have read that it is not safe to drain to 0%. I'll try to completely drain it tonight and recharge. Will report back.
btw, I noticed that when the battery is charged to 100%, the led stays amber for about 15-20 minutes before turning green. Is this normal or should it turn green immediately after reaching 100%?
Tried completely draining the battery and charge overnight but have no effect. The problem persists. So this is definitely not a battery problem.
I guess the last thing I can try is charging the battery with a standalone charger or another HD to see if there is problem with the charging mechanism in my phone.
The latest Telstra rom seems a bit better on battery
led amber
The led amber must turn to green
immediately after unplugging.
some thing is wrong with your charge
system .

aidinali, can you please explain what you mean? I thought the led will go off if you unplugged the charger. My problem is that after reaching 100% as indicated on the phone, the led stays amber for another 15 minutes before turning green.
Well , I'll correct & explain more....
1-when you reach %100 ,the led will turn to green immediately (if you’r phone is plugged in).
2-if you unplug ,the led will turn off (as you said ).
The problem is that since the battery meter in HD has not been defined by percentage , it doesn't match with
Apps like battery level or battlog .so when you see %100 on them , it' s not "real % 100 ".
I believe there is something wrong with the phone as the percentage usage and charging status do not match. However, since the basic HTC software does not have any battery usage in percentage, it’s hard to convince the service centre that something is wrong.
Any software that shows the battery as a percentage all have the same reading, so I assume they all rely on the mainboard for that information. There is obviously something wrong with either the charging process of the phone or draining more battery than it needs during usage.
I have 100% exactly the same problem as in the original post.
Does anyone else?
I have also tried 2 batteries and had exactly the same results with both, so I also know it is not the battery. The only app I have installed other than Dutty's 6.5 rom is Tomtom which does not need to be run for any of these issues to occur.
Any chance on warranty? I think it's software...
Try a different ROM. I've been having the same problem. I just flashed a new ROM about an hour ago (partly because Dutty's 6.5 kept freezing). I'm hoping both problems will be solved now.
i've found the latest radio rom to make a big different to battery life. 1.14.25.24_radio
the previous radio rom (1.13?) did suck the juice and made battery last 2 days less than 1.14
Try charging with a different charger. Ie. connect a USB cable on your PC and charge it from there.
I've had very similar problems with the stock charger a month after i got my TouchHD, and ended up testing with my old P4350 charger and all problems went away.
I've had similar drains even witch WiFi off, no emails, exchange or 3G access...
Now i'm getting a whole day's usage and i'm left with 30-40% battery, with 2 hours average talk time
I've tried with a number of chargers.....battery still sucks.
I've just switched from Dutty's to Energy ROM, radio is 1.14
If anything...energy drains more quickly than Dutty's
It says it drawing 350mA
Ok, I've used Energy ROM but now using Dutty's Leo. The only thing I've loaded so far is Battery Guard which say it's drawing 98mA when on standby(ie....backlight goes off). That'sa massive difference on the 250mA readings I used to get....now all I have todo is figure out which program I'm loading that is killing my battery.
That still only equates to 12 - 13 hours on a good standard battery with no use at all.

Standard battery should last longer. Sounds like your battery may be slightly faulty. Make sure you let battery drain fully before charging, and always try charging with device off. Should help improve strength.
I had same problem when i flashed miri's rom, hd got warm and didn't last, it cooled down in standby, the answer to my problem was that the wifi was not set to save battery mode, once i set it to save power everything was ok
Used 8% in 24 hours

Have been trying that for a month now....something seems to have suddenly worked It only used 8% of the battery in 24 hours! I live in the rainforest with no service so cellular was turned off...wifi on, but I only accessed it about 6 times......still,nothing has changed. The same conditions would leave me with a dead battery in 7 hours previously.
Time will tell if it keeps up this well.
By the way....Thanks
So basically you're saying people should drain down the battery to 1% or so and not to 0% (device dies when battery is out) to get a better battery strength?
Seems to be the general consensus. I'm still not sure if that's what made the difference for me but previously,I would put my device to standbye when I went to sleep at 10:30pm and it would be dead by 6am
Hi,
I noticed the following problem on my Diamond 2:
If I turn off the phone for night charge it never shows green in the morning.
The only way to see that amazing green light is to charge the phone whent it is turned on.
Of course I applied the latest hotfix - no use for the off mode charging. And of course I wrote to htc - will not waste your time repeating their suggestions.
And I am not happy with my phone battery life - it hardly endures one working day - lets say - 10 hours...
ROM - Official, yet.

I never turn my phone off so the green light problem never arises. However I will check and see if occurs.
As for battery life, you will need to give it a few weeks of use before you see maximum battery life.
Make sure you don't continually discharge the battery (better still keep it charging whenever you can) and you should see improvement over time.
Unlocking and replaceing the ROM can also have a significant effect on battery performance as does the Radio version in use. That's going to need some work on your part but the improvements are there to be had.
Some apps that are in common use are also power hungry and can cause a significant drain on power.
And if you install your apps to mem card then again that uses more power than installs to phone storage memory.
You can also turn off any unused background apps and processes.
Only turn on Bluetooth and WiFi when needed.
All these things help.
Personally I carry a spare standard battery with me at all times and strangely since I bought it I haven't needed to us it. The placebo battery effect?
Thanks for the answer.
About the battery usage conseption:
You suggest that I plug my phone each time when possible?
I thought that as the battery has XX recharges according to the specifications it is not good to charge each time whenever you got AC or USB access
I started to follow your recommendation anyway.
For example however - my laptop is never (when possible) with battery in it. I use the battery only when necessary, becasue in the user manual is written that has 300 cycles of recharging. And I always wait until completely discharged before charging. That is how I began treating the Dimond, too.

With Lithium Ion batteries the "quoted" numbers of "rechage" is is an approximate equivalent to give some idea of life expectacy.
It's a hangover from the old NiCad battery days and is not really very helpful when applied to Lithium Ion usage.
The most important aspect of LIon is it's ability to hold it's voltge at max current for longer than other technology. It does this best when well charged and maintained at near max as possible as often as possible. The downside is it's life expectancy which does deteriorate over time.
If you require max daily useage then max charging whenever possible will give you this and you will have to accept that the battery will at some point loose it's charge retaining capabilities and will have to be replaced.
For most of us that's the most important thing.
This is not a battery issue, I believe that this is a software one.
I noticed this morning, having left my phone on charge, and 'off', all night, that the indicator light was still red. When I switched on the phone, it showed only 80% charged.
Having seen this before, I carried out a soft reset, the battery indicator then showed fully charged.
So the battery is charging fully, but the battery charge indicator is showing less than that.
Hi My hd2 this morning run out of power and you know what?!! When i charge it back and power on, it go to hard reset!!!!!! OMG I just want to use till the last drop and charge it to max.... BTW I am using the Andida 1600, tested for a few days and still ok compare to HTC. Any issue of the problem if using that? Thanks.
I haven't let it run down to the last drop. It does warn there may be data loss when the battery runs too low.
It should not do that when emptying the battery until automatic shutdown, I've done it several times. HOWEVER, that's with the original battery. 3rd party ones often have a less accurate metering chip, the warning comes too late, and by the time auto shutdown kicks in the battery is too deeply discharged for a clean shutdown. Probably due to your andida battery.
Well I did it again since already gone(data) and this time it boots up as normal. I had omnia(i900) and it works fine with this process...any way thanks.
Thanks Kilrah and noted. I will be more careful next time.
The scenario is this. I charge it every night. The orange light does work and it will show 100% in the morning. It will then shut down at random times and when restarted say the battery is low. I can plug it in again and reset it and it will show from 0 to 100%. Once I take it off the charger it may run all day and deplete the battery or it may die suddenly and tell me it's got a low battery again.
Should I consider the phone dead or does it sound like a faulty battery. It is the original battery and is 2 years old.
Marksm,
I think could be caused by:
1st: some hidden app wich consume a lot of energy that is placed on your phone or
2nd: a phone virus made to produce that behavior or
3rd:a battery control software issue.
For that, I'd advise you to:
1st: verify the programs and process that are running on your phone, seacrh for unknow ones and see on the internet what they do so you can remove the unwanted ones;
2nd: install one or more of the mobile antiviruses (one at each time) that are avaliabe on the internet and perform a full verification of your PDA;
3st: put a new ROM on the Blackstone; but first read how to do it well, if you don't know how, and be sure to be aware about all issues and risks that this action may bring.
Wishing you a good luck!
Stay in peace!

I have exactly the same problem. I restored the original ROM and SPL and nothing has changed.have you tried another battery? Is like the battery controller is broke. The phone is under warranty but the battery is not covered, so I would know if send it to HTC or to buy a new battery!
Similar issues reported in a post above. A new battery seems to have fixed it but needs more time to tell. I will probably order a new battery too.

me 2 going through the same problem.....really wanna get out ov it..
Hi there, I currently have a Samsung Note 4 running CM12.1 and in the past two days the phone has randomly "crashed" late afternoon/night (5.30pm today and 8.40pm last night). My phone performs fine throughout the day and then I'll notice that the screen doesn't wake up if I press the home button like normal. If I then power the phone on it boots up and instantly powers off after booting since it has "0%" battery. Both times the phone had plenty of charge in it, around 30-50%. Has anyone else encountered this before?
I have some screenshots but I am unable to post the Imgur links in my post because of my post count. Any other way I can post them?
Specs:
SM-N910F
CM 12.1-20151022-NIGHTLY-trltexx
Android 5.1.1
I can provide more specs if you wish.
Buy another battery, if another battery is OK then your old battery is broken
I had a similar issue where it would, after a clean software reset, shut down unexpectedly at 20% or so - then subsequently at 40%, 60%, and further 20 percent increments when I'd let it shut down of it's own accord. RMA'd it under warranty, pretty pleased with the service I got. No software fix for it.

Recalibrate your battery. I had this issue, too, after flashing another ROM. My Note 4 would shut down and die at ~50%.
1. Download Battery Calibration from Google Play
2. Fully charge your phone. By "fully" I mean not only to 100% (which, in your case, will be something like 50% effective charge), but until your LED has turned green. For good measure, just turn your phone off and let it charge overnight.
3. Run Battery Calibration, and tap the big button that says "Battery Calibration"
4. That's it.
You should do this every time you flash a new ROM, because there's always a chance your battery gets miscalibrated during the process.
Thank you very much for your help everyone, I'll try the Battery Calibration and let you know if it fixes it!
