got htc hd2 2days ago had to charge 4times

hi all i have had to charge this phone so much its kinda doin my head in, last night i charged it and took it off at 6pm fully done and my 11pm after taking approx 30pics + 4vids(4min long each) it was down to very low life.
so i chargeed the battery fully again, and this time from 8am ~ 10am today my battery is at 77% i have done sofar
*backlight set @ 30%
*hspda ON
*Weather, facebook download every 1 hour;
*1call, 5min
*3 SMS got, 5 SMS sent
*1hours playing with phone (general settings)
*took 10 photos
*took 1 vid 3min long
from 100% to 77%,

Simple, turn off 3G. On regular GSM my phone was at 37% after 12 hours with at least 30min talking, lots of browsing, emails, texting, and 30 minutes GPS.

did u run with 3g/hspda on before and did it improve alot or not, as i use net alot and really nead hspda

TBH I doubt you are fully charging in 2 hours. The iPhone is the same, fully charging is not till the meter says 100%, that is more likely 80%.
The battery meter may also need calibrating. Personally I would drain the battery dry by running videos etc, and then charge it back up and leave it charging overnight.

i charge it alot longer till green light came on not two hours matey, it took two hours to lose that much life lol
ps. i will run a satnav a few hours should run life down and then recharge

My battery was draining fast too. I realised it was because it would stay connected to my data (mobile web for O2 in my case) and never disconnect. I only clicked on the notification bar and saw i was connected to my data for over 1 hour and half. That is a big battery drain. Don't switch to gsm mode - that would suck. What is the point of having such a high end phone and use it in gsm mode?
All I can suggest to you for the time being (until someone figures out how to have data connections auto disconnect after a couple of minutes) is to disable auto downloads for the following:
facebook, weather, mail, stocks, time sync, twitter etc.
You now have to check manually these items. Sucks i know but only way for me to not stay connected to data and drain my friggin battery

That happens to me too..I have everything set to update manually! No internet time no twitter,weather etc..And no other apps!!! And it still connecting by itself and stays this way for hours till i notice it!! Any ideas of what does it try to update??
(dont tell me the obvious ones!!)

ok sounds like a good plan matey, im currently playing a video over and over to kill my battery 0% then im going to charge from no power while phones turned off, 5% life left lol....common...
i keep getting message battery low may lose data is this true will i lose data on my fone?

on the old PDA's if you drained the battery ( <1% or something like that ) your data can be gone, its like performing a hard-reset... don't know how it is now though... propably its safe, or it turns off before 0%

You don't have to worry about that any more. A different type of memory is used. You can even take the battery out and leave it for days and all your programs and data are still there.

ok people i completely deaded the battery till it wouldnt turn on and started it charging at 15:43, its now 17:00 and still showing orange led light so i will keep checking every 15min to find out...
1) how long to charge from total flatnesss
2) how long battery last tomorrow on full charge from now to when it conks out again
will keep you updated

just for information: HD2 has a battery that needn't get totally depleted to get the full charging cycle like on older battery packs. On the contrary, the battery suffers when completely discharged. It is recommended not to leave it till the phone dies, this reduces the battery life. Charge it whenever possible. I have mine in active dock when driving in car, as well as when in office. I know the battery life could be better but well...

I would imagine video recording puts quite a strain on the battery.
Also don't forget that gorgeously massive screen runs from a 1200mAh-ish battery. I have the Xperia X1, with a 1500mAh battery. When I get the HD2 I can't help but feel there just won't be enough juice to go around.
Lower battery capacity + bigger screen = ever-so-slight reduction in battery.
I wonder whether captive or resistive screens take more power?

I'm using wi-fi at home for all data and the battery is lasting forever!
Strongly recommend tying this - see if it works for you?

ok all i have the full charge time of the battery, from complete flaness 0% life to full charge 100% life time taken
start 15:43 ~ finish 18:12 = TOTAL 3:19min.
now i will take note of all i do on the device and post results tomorrow or the next day if im lucky and it last that long lol

Also the way you charge your battery affects the charge time.
Example:
- Charging through phone using stock charger
- Charging through phone using third-party charger
- Charging using a short USB connection
- Charging using a long USB connection
- Charging through phone with phone off
- Charging through phone with phone on
- Charging through official external battery charger
- Charging through third-party external battery charger
Sometimes stock accessories are slower, others, not so. Some manufacturers refer to a "power charge", for example some Sony Walkmans. For that to work though the phone / device has to be off. Thats how they get those 3min = 3hr charge times.

Erm that's not what I advised. The aim was to re-calibrate the battery meter. All you have done is wait till the batery meter says 100%, whether in reality it's 80%, 75% or whatever. A full overnight charge would have guaranteed that 100% = 100%.
I don't see what you've done other than continue to use it the same as you already were.
I said I doubt you can get 100% in 2 hours, 3:19 isn't much more.

No he's right, completely draining the battery isn't good and shouldn't be done too often. regularly topping the battery up is the way to go.

hi i plan to monitor usage till battery drops dead and then tomorrow night or the net if im lucky i will redo the recharge test over night

Possible battery problem?

I have charged my Nexus One yesterday for the first time. I live in holland so i had to use my USB cable, and the power adapter that came with my HTC hero to plug my USB cable in.
After the phone was charged 100%, i disconnected it from the charger and only downloaded + added a widget to my home screen. After i did that the battery was already down tot 97% :O:O
Is it defective ?

i noticed having to complete a few charge cycles.. charge fully, use it till dead, charge again
now it seems to hold out much longer

Hmm ok i'll try that. But did yours also drain this fast?

what setting is your screen on? seriously though, im sure some other battery experts here would know, but i think they take a few cycles to get to maximum efficiency

Sorry totally new to the phone hehe

I've noticed this too. However as soon as the battery reaches around 50% it takes a lot more to drain so it evens out in the end I guess

Hmm ok so it also went that fast on your phone? i have been using it for about an hour now and its down to about ~90% =\, concerns me a bit.

Found out something else, concering the usage of the screen. When i look here:
Menu -> Settings -> About Phone -> Battery Use
The phone tells what uses the battery the most or something, but the strange thing is that it says:
Display 55%
Isn't that very high? Maybe that is causing my battery to drain so fast

Battery meters are not an exact science. Its using what it knows about the battery's state to guess of how much % is remaining. The battery meter will need to be calibrated once, and then overall battery should improve with your next normal 3-6 full charges.
Again, you do not need to and you shouldn't repeatedly drain the battery to 0, only once is this needed to set the phones battery meter, unless you clear it (possible within amon ra's bootloader).
As for your observation, yes that is completely normal, there is not a whole lot of definition within 3% of battery as far as displaying it. What the real picture? Enter in #*#*4363*#*# on your dial pad and then go to battery information, and you'll see the accurate voltage. (this is also accessible from "spare parts" if you have it)

All %'s here are vs the amount of time on battery (shown at the top in h:m). If you just unplugged your phone and you go looking here, you'll see the display % VERY HIGH... because the screen has been on the entire time its been unplugged
Its a % after all of the usage since last unplugged.

i've noticed my battery life is much better since i got the desktop dock.. lots of people charge until the light turns green then immediately grab it and start using..
leave it for another hour or two and it seems to get much better.

dont know if anyone else has noticed this but the top corner indicator light turns green once the battery goes somewhere over 90%, leaving it charge longer will get you to 100

You probably found this by now, but one flick to the left and you should have a widget for WiFi, GPS, etc. The far right one toggles 3 levels of screen brightness. The brightest two settings really suck down battery.

just a tip, when you are draining it to recalibrate the battery, after you get to the point that the phone shuts off, boot into the bootloader and run that thing till it completely dies... i did this for my phone, sat it in bootloader with a bright ass screen for like 15 min before it finally finished off... get every last ounce of juice out of it before you start charging it back up

Hmm thanks for al the reactions guys. I'm going to recalibrate my battery now, and lets see if that helps a bit .
Then i have a other question, its not about my battery but since i already have a open topic i dont want to create another one .
Can anyone of you test the following:
When you are calling with someone, and your calling volume is on the maximum (so the volume of the speaker that you hold against your ear). Can anyone notice a little crack from the speaker when the other person talks a bit loud or make's a loud noise? I'm wondering if there is something wrong with mine. With several tones the ear speaker cracks a little bit, like the sound is to loud or something?

Yep sounds about the same on my phone, dont worry about it lol
The draining thing is from the old nickel days, the lithium batteries are made for daily use so just treat the phone as you would normally. The battery will get better as time goes by.
Also I am not having that problem with the speaker

Hmm, I have my device since last week (Netherlands) and the battery usage is frightening. Sucking it dry in about 24 hours. I haven't let it die out completely though: I thought lithium batteries were not supposed to be used that way. Ni-Cad batteries were used that way.
Ah, see here:
Guidelines for prolonging lithium-ion battery life
Lithium-ion batteries should never be depleted below their minimum voltage (2.4 to 2.8 V/cell, depending on chemistry). If a lithium-ion battery is stored with too low a charge, there is a risk that the charge will drop below the low-voltage threshold, resulting in an unrecoverable dead battery.[citation needed] Usually this does not instantly damage the battery itself but a charger or device which uses that battery will refuse to charge a dead battery. The battery appears to be dead or not existent because the protection circuit disables further discharging and there is zero voltage on the battery terminals.
Lithium-ion batteries should be kept cool. Ideally they are stored in a refrigerator.[citation needed]
Aging will take its toll much faster at high temperatures.[citation needed]
[edit] Prolonging life in multiple cells through cell balancing
Analog front ends that balance cells and eliminate mismatches of cells in series or parallel significantly improve battery efficiency and increase the overall pack capacity. As the number of cells and load currents increase, the potential for mismatch also increases. There are two kinds of mismatch in the pack: state-of-charge (SOC) and capacity/energy (C/E) mismatch. Though the SOC mismatch is more common, each problem limits the pack capacity (mA·h) to the capacity of the weakest cell.

So, if you want to brick your battery, by all means, suck out all the power.

i have a mytouch but i think the things i do can be used with all androids....first recalibrating is a good way to get a fresh battery...then the brightness also helps along with any wireless things u dont use like wifi gps etc.. they should be turned off an brightness should be low...i have downloaded a app lately called automatic task killer..i think this is better than any other task manager because other task managers dont kill apps wen phone is on standby ..apps r still running wen screen is off an automatic task killer kills them..i think u should download this and also have a task manager to kill apps wen u use the phone..another thing is charging the phone wen its completely off..wait until the the light turns green then leave it on for another hour or two then turn it back on....i have seen an increase in bettery life by doing all this...any one esle have any tips ..let me kno

[Q] Battery issues

Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?

Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.

Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??

Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...

Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_

this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.

Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........

Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?

Horrible battery life

My Huawei has a horrible battery life. I'm using stock rom (rooted of course) and the battery drains really fast, like 5-10% an hour even in sleep mode. I have used a battery calibration app recommended by someone here in xda, but I don't think it made any difference. My last Android phone used around 1% an hour, even with data and sync on, but with pretty much the same settings, I can hardly make it through the day with my Huawei.
So, what to do? I don't need the battery to last for days, but having to recharge twice a day at worst is just too much.

My battery drops around 7-10% overnight.
Probably a defective cell?

mine after i installed custom rom (b160) and a battery calibartion in flight mode during my sleep after 7 hours that passed and woke up it was 1% dropped and now 7 almost hours afterwards in normal mode it has dropped 7% with very light use of course...
i want to say just that with gsm active it drained 5% more than in flight mode...
so something must be going wrong , like you don't have a good signal and it uses much power to keep your connection alive and have better signal....
i must say that i have a profile with setcpu when the screen is off with min 122 and max 460...
and just for the record i think that with custom rom also mine was dropping more...
i don't know why although...

Noticed this myself. i use spotify alot on the phone, walking, bicycling, at the gym. and it drains a whole lot of power even in offline mode. but if i set it in flight mode the phone last for hours and hours without even dropping 5-10% of power. but when gsm or data traffic is on the battery life just drains out so quickly! so it is definitly something serously wrong in this rom. Im hoping gingerbread is coming soon to this phone, so maybe all these small issues has been fixed.

I've found highly variable battery life. Sometimes it's awful, almost 50% overnight when it's sleeping on my nightstand, other times it's much better and only drops 7-10% under those conditions.
One thing is Google Maps, even when not in use it seems to suck battery like crazy if it's loaded (and it has a habit of getting loaded even when you don't run it or any apps that use it). There's a long thread on this in the Google support forums, but no sign of a fix from Google yet.
I've found doing a 'force stop' on Maps if it's running often helps, another thing is to reboot the phone after you charge it, that seems to fix it for several days sometimes, but then it starts sucking juice again for no apparent reason, so I tend to reboot it after each recharge. There can also be other apps that due to bugs can suck battery, for a while there app killer did this but the author put a fix out pretty quick and it shouldn't be an issue now.
Just noticed that there's an Android update from Huawei now available for download, maybe that'll fix some of the irritations and help with battery life; I'm off to install it!

where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?

My phone has been on for nearly 48 hours.. charging it right now. I played, connected to wifi, browsed the net, facebook, gmail etc.. and I really played hard on it for a few hours.
30mins ago it switched off, dead battery.. I'm quite pleased with the battery life

Exactly the same problem here. I formatted now both the internal and external SD card, let's see if that helps.
edit: No it doesn't. The problem seems to be that my phone doesn't sleep properly. I charged it to full, then turned the screen off for one hour. App called Spart Parts shows that since last unplugged, time spent without sleeping is 36m.

it took mine 2 weeks to get to the full battery life. now i get 36-48 hours from it.

After 5 weeks i get about 12hrs. No GPS, no 3G. About 10min ago i took the charging cable off. Now Battery History in Spare Parts show that "Since last unplugged" time spent without sleeping is 10m 33s (99.9998%), and time spent with screen on is 3m 23s.

im thinking of buying this phone is it available in India ? also can this device be rooted n what about the custom roms ? are they available as there is nthng on XDA :'( . And what about its battery life even being 1500mah is it so awful ?

Now after factory reset it seems that this is fixed. Over night with Wi-Fi and all sync's enabled, it took about 20% which is quite ok.

The problem is back... For some unknown reason the phone doesn't go to sleep and starts to use more battery.
Battery History:
Other usage, since last unplugged:
Running (100%)
Screen on (3,2%)
Partial wake usage, since last unplugged:
Android System: Total time: 13s
Dialer: Total time: 0s
Maps: Total time: 0s
It seems that reboot helps with this every time. After reboot, running-% is 32.9 when screen on is 6.5%. It would still be interesting and helpful to know what causes this.

its an android thing

Do you mean it's a common bug, or is it normal thing for Android to not go to sleep after few hours of using the phone?

That's not true. My battery history shows that correct(as far as I can perceive) running time.

I get most of the time also. But after charging, at one point (after some time) for some reason the time spent without sleeping goes to 99%. The problem is, that the partial wake usage doesn't show that something is wrong. Usually restart helps, but sometimes it can be already late, because 100% running has already taken quite much of the battery.
Also, when the time spent without sleeping is 99% or 100%, the CPU is still NOT in heavy use. So something just prevents the phone to go to sleep mode, and it seems that it is not the CPU that causes it.

where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?

I got it through the phone, it was the 2.2.1 B136SP02 update. Not online at Huawei website. It doesn't seem to have improved battery life alas (or the frequent WiFi dropouts I've had since new, particularly while downloading app updates). Main feature of the update is WiFi tethering/hotspot support, at last...

What seems to have worked for me after a couple of weeks++ of REALLY crappy battery life is a battery stats wipe.
FullCharge while the phone was off. First boot in recovery, battery wipe and then i just let it run close to dry before the first charge (almost 48 hours of medium use). Note here that i am now using the charger that came with the phone because i noticed that my generic usb one had an output of 0.7A instead of the full 1A of the factory charger.
Another point arose however. Does anyone else have stability issues when battery drops below 25%? I am talking about some serious crash/reboot/lag/noradio issues.

Trick to save battery

Hey all, I had been really dissatisfied with the battery of XSP, leaving it overnight from 90% it used to drain to 50% with all apps being turned off so there's finally a way which you can use so the battery doesn't drains out quick I tried it myself last night and from 87% battery when I saw in morning battery was 83%, awesome isn't it
Ok so here's what you have to do just add the line below in system/build.prop add it in bottom of build.prop enjoy
"ro.config.hw_power_saving=1"

hmm, gonna test it tonight

Good one
But for me no battery draining issue while stamina mod on. Yesterday night i leave my phone with 34 % battery with stamina mod on while sleeping . In morning its 32 % ..

before i sleep, my phone's battery status is usually 20-25% and i charge the next morning before going to work. when i woke up, my phone doesn't drain a single percent at all, but sometimes the phone's battery status is reduced by 1%. just sharing.

build.prop
According to some one website, it should:
# allow to tear down mobile data connection when device is idle
I think you can achieve the same by stamina mode.. The question is, what is causing so much drain. Try to install BetterBatteryStats or similar app to find out the real reason.

The phone ignores lines starting with # so no it shouldn't be. But the stamina mode probably does the same thing indeed

Yes i know about the # lines, I just posted what does this settings actually influence. It shut downs mobile data while screen is off, which is achieved by stamina mode as well.
BTW, what else does stamina mode do? You can choose which apps will be active in the standby mode... in case i have email synchronization set to 30mins, an don't touch the phone for 2 hours, then it won't be synced? If I add it to stamina mode apps, it will be sync then?

battery while screen is off is perfect on my sp.. i dont know whats the matter with yours.. but the problem im facing is during a movie.. of approx 2 hours.. the battey level is 90% .. after two hours it drains to 20%.. with 50% brightness ... its kinda odd.. if you guys are feeling the same.. or not.. at least give me some advice on this!! i dont think this is normal for sp whose video play back is almost 7-8 hours!

m not facing such an issue.....the other day i watched 2 hollywood movies both approx 1hr 45 mins+ with full brightness on MX player and from 90% the bettery went down to approx 30% so that was like 60% drain on full brightness for 3hrs+ movie

I know there isn't much problem of battery with stamina mode on, but even while stamina mode is off or watching videos, playing games it still saves a lot of battery from being drained!

Greenify + Stamina Mod = perfect battery :thumbup:
