Hi
If the battery falls below 10% then it turns off wifi, sd card etc (Fair enough).
But... unfortunately, unit switches on every 5 mins to tell you that the battery is dead (then does not switch off for the defaut timeout)!!! You can go from 10% to dead in half an hour even when the device it switched off.
Also, when you feed it some juice, and try and start the wifi, it switches it off again until the charge is above 10%. I.e it does not realise that the unit has a mains supply connected.
At leased it does not hard reset like my BA used to!

Did you ever find a way around this ? My MDA Pro just drained itself overnight because of this bug. It's even worse if you have MS Voice Command because that chips in to TELL you that there's low battery !

I also could do with a solution for this, as i have set my Screen to be alway on if in laptop mode and open. Oftern i forget to close it and the battery goes flat. No big deal because of lest you looses everything. But not untill the battery once pluged in goes above 10% can i use it properley as all my programes are stored on the card.
I agree the 5 minute but to keep telling you its flat makes it worse if your battery is low, But is there a way to change the low battery shut down to 1% so this way after only a short charge i could start to use it properley
Thanks

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
Superb rom, working flawless. Absolutely perfect but is this normal.
Running Pandora on 3g is only good for 4hrs of battery life. Is this normal?
On wifi 10+ hrs streaming music. Is there a work around for the life on 3g?
i just installed the syndicate 1.01 rom last week and depending on what i'm doing i have easily more than doubled my battery life....as an example, i can watch a 2hr movie with the screen set to auto brightness and i am still about 70% battery life....on the stock froyo rom my batt was around 40%...no joke.
that being said, pandora is a huge battery hog, especially if you are in a not so great 3g area....
maybe you went through the usual battery 'fixes', but this is what i did after installed the rom....
1- reboot clockwork and wipe the battery stats...
2- got this info on this site from a post several mos ago to calibrate the batt...
- Phone is on. Charge untill told to unplug charger.
- Unplug charger and turn off phone.
- Plug in charger and charge until phone beeps (about 1-5 minutes)
- Unplug charger and turn on phone
- Charge to 100% again (1-5 minutes)
- Unplug charger and reboot.
3- get the free version of JuiceDefender and leave at default settings
4- always always always stop that pesky 'drm' service from running
5- not sure if still needed with this rom intalled, but do the airplane mode on/off switch after a reboot
i hope this helps.
I get great battery life on ACS....if I'm not streaming music over 3g, no matter which app I use (Pandora, Sirius/XM, DI, Xiia). If I stream over Wifi, my battery life is fine. This has been the case no matter which ROM I'm using. It's probably because I stream music at work where I have a weak 3g signal. Does anybody get decent battery life while streaming over 3g?
I seem to be having problems with the way my nexus is reading its battery capacity. Pretty frequently now the 15% battery warning comes up, and a couple minutes later it's buzzing in my pocket to tell me it's at 5% or powering down, when it couldn't possibly have used up all that battery power in that time.
I also have issues where sometimes I plug it into my charger and in a few minutes it already says 100%/fully charged, then when I unplug it it reverts to 30 or 40%. In general the phone seems to have problems with telling what its actual battery level is. Has anyone encountered a problem like this, and have a suggestion of how to fix it (short of a factory reset)?
After I upgraded to Kitkatt i have noticed bluetooth appearing in the battery percentage. I have read from others about 5-10 percent maybe but my battery drain is ENORMOUS given the way battery was before kitkatt. I have done a full factory reset and wipe. It seemed to fix it and i was so happy. Now it s back and i have no clue why. I don t use location services. Battery saving button is always on and i keep it to minimum usage.
Ps: the screens were taken a few mins after i woke up. So there was no active usage on the phone during the drain because i was sleeping.
Ps2: Bluetooth has never been turned on. I do not use it.
Ps3: This happens in bursts of battery drain. 5% may be used while i wrote this post and some facebook use for 1 hour, and after a while in 1 hour of leaving it on the table i will lose 10% from Bluetooth.
Tldr but did you try hard reset the phone?
Also try rebooting the phone in safe mode by holding power of button and then when power off menu comes on, hold power of for 3-4 seconds to reboot in safe mode.
Let me know if any of these work.
Hmm its weird that you have such an enormous bluetooth drain in the first place, and in the second place that bluetooth isnt even enabled??? You could maybe post an logcat also with enabling/disabling logcat since maybe bluetooth got bugged in a weird way on your system. Please quote my post since else I may not notice your post and then I can't respond back.
