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
running a flashed stock 4.0.4 ICS ROM, Rooted.
everything was running great. battery life was one of the more amazing parts of this tablet. then one day last week i had it on the charger half the day, went to go grab it, wouldn't turn on.
after lots of button pushing, swearing, about 30 minutes of it, i put it back on the charger. 10 minutes later i got a blue battery symbol charging and i held down the power button for 30 seconds and it turned on. since then have had no issues with it working, except battery life is poor. the initial time after i used it, the thing lost like a percent every couple of minutes just sitting there. it was dead within an hour and a half or so, barely touched.
i charged it fully, and reset the battery stats via battery calibrator (even though google says that is useless), then i let it drain to 0 with usage and charged it up again. now the battery life is pretty average. i lose about 10% every half hour on wifi browsing the web, screen at anywhere from 15-30% via Lux, and checking to see if anything is running nonstop in the background. so that gives me only 5 hours of total battery life just browsing the web. before i was watching HD movies 2 hours long on almost 100% brightness with some browsing and messing about in the middle and losing 20%.
i have better battery stats installed and the tab is going into deep sleep very well. also it is barely utilizing full speed, it is rarely at 1.2ghz, usually at 500mhz or 200mhz if not deep sleeping.
a couple times i had some partial wakelock issues but nothing bad. but every other day, the battery life just goes fast just doing regular stuff. nothing unusual going on in the background.
anyone else have this happen?
if i do a full reset can that help? or is this a hardware failure and time to call samsung.
The best battery life I have ever had was on Quicksilver 0.9. I got about 13,5 hours with the display on (WiFi off and airplane mode on)...
On a stock rom u should get about 10 hours with the display on.
On cyanogen-mod ROMs I am experiencing the same thing as you. The battery is dead after ~7 hours.
I would suggest to restock the tab, wipe it and just run with the apps you really need. Maybe even try Quicksilver and to be 100% sure u could even flash the ROM when the battery is at 100%.
What does the battery stats in the settings-app say?
battery settings shows nothing that could be a culprit. this thing deep sleeps like a champ.
screen off just laying around i won't even lose a percent an hour. just all of a sudden i went from being able to browse the web on wifi for 10 hours, to 5. all after that weird time the battery drained super fast.
i wiped cache and dalvik cache, same thing.
going to try reflashing with the newer ICS posted recently. UK Q2 based and see what happens.
P.S. how long until i can post more than once every 5 minutes?
I have Problem With Standby Time .....My Battery After 12 Hours Standby Have 50% Drop.....I install Stock Rom But Itsnt Fix...Please Help Me:crying:
( I do wipe cash and wipe battey and calibrate)
new ugsrii
how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection
Green power
Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
Hello in these days i having facing fast battery draining even in deeep sleep, but after some research i maybe found one solution its very simple:
1st: Charge your phone until 100%
2nd: Turn off and pull out the battery for 2 hours or more
3rd: Put Battery and Charge your phone again until 100%
4th: Remove battery wait half hour or more
5th: Put the battery again and charge the phone until 100%
6th: Repeat the process until when you put the battery the phone is charged at 100% or a little less when this happens make a battery calibration with this app https://play.google.com/store/apps/...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd or a similar one, or in cwm wipe battery stats
Please if the post if repetead delete
Share your sucess or completly fail
For me works im about 1 hour with phone connected (deep sleep )and only drops 1 % before i made this "recalibration" my phone drops about 5 or 6 % in one hour after 12 hours almost all time in deep sleep a little time in wi-fi and one little call and only drops until 90%
Issue 1 -
I always fully charge my phone. But, sometimes if I discharge it at a (%) below 100% than it stuck at that (%) for almost 15-20 minutes even after continuously using it and then discharges normally.
Ex :- If I discharge it at 57% and then start using it. So, the battery % will stuck at 57% and will change to 56% after 15-20 minutes or more.
Any solution to this?
Issue 2 -
I am using this device from 2 years but after I moved to stock rom in July 2019. I saw a weird issue i.e. If my battery percentage is 84% and I am using it for 5 minutes. So, now it should change to 83% it changes. But if I press Power Button and lock the device and then unlock the device, then it shows 83%. In simple words, the battery % changes/refreshes/updates immediately when I lock the screen and unlock it. With Screen ON it takes time to change %. My phone gives almost 5-6 hours Screen on Time and I am fine with it. But why these issues exist?
Any solution to this?
PS:- I have calibrated the battery many times, but it doesn't fix these issues.
If you know fix regarding any of these issues, please reply and mention for which "Issue (1/2)" you are telling the fix. ?
