1 day until battery is empty..?!

Hello, got my Touch Pro ago 2 or 3 weeks. Lately I noticed a rapid decreasing runtime...
I had the phone the whole night (~8hours) connected to the power-adapter
and this morning around 8am it said the battery is completely full. Around 6pm (less then 12 hours) it automatically turned off.
First I had bluetooth or the weather-update under suspicion, but it was all deactivated. Then I turned of anything that would need a connection to the internet (and even with that sporadically on it shouldn't be empty after 12 hours!)... helped nothing. The last thing I thought what might could be the reason was the "SensorLock"-utility. It locks the phone after it goes into standby, nice if you keep it in the leather-bag and you get calls. But even uninstalling that prog didn't help.
What do I do now? If I send it back to Amazon it takes weeks to get a new battery or phone (German amazon sucks). What about HTC itself? Do they have some battery-replacement guarantee?

How much did you use the phone? Where you texting a lot or calling alot? I text about 100-200 sent messages a day, and my phone lasts about the same amount of time.

Nope, no phonecalls (beside one short incomming call) or shortmessages at all. Used it just 30 mins for playing music out of the loudspeaker and to get waked in the morning by the alarm. +300hours standby should'nt be 12 hours if I just use some progs and the display...

The best thing to do is cycle your charge. Leave the phone on until it shuts off and cannot turn on. Then recharge in the off state. Do this and your battery will last longer.

Also, don't leave your phone charging for longer then necessary. I've killed many a phone batteries this way. It should be come general practice to fully charge your battery before you do anything with the phone upon initial receipt. Most phone batteries come with a partial charge, but you should always follow the instruction manual.

I'm not 100% sure, but don't most modern high-end electronics have technology in them that make sure that the battery is not "over-charged" so to speak?

my t-mobile mda, nor my 8525 didnt...
or maybe i was just the victim of two faulty batteries on different phones.

Wow, another battery thread....
Could you please, please use the search option or browse through 4 pages before making a new thread??
Time for a lock.....

i was getting really crappy battery life ( i have a fuze) and this is what i realized:
- romeo's rom kills the battery on the at&t fuze
- S2U2 also kills your battery
-Touch flo is not great for your battery either
i've flashed NATF's rom, and disabled s2u2 (still running tf3d) and i still have about 40-50 % battery life after a full day (medium usage)
good luck
omar

use search...
there are apps that run while your device is off
also, things like 3g/hspda run the battery down quicker
and batteries cant be overcarged these days why would they invent cradles if they wanted us to let the device fully run out before charging again?

For two days in a row I have charged my Fuze before going to bed. I made sure it was fully charged, pulled it off the charger, went to bed, in the morning the phone was on it's last bar. 8hrs of sitting on my desk and the phone fully discharges, something is not right here.

Run Adv Config, & turn 3G off when not using 3G.. It's almost as bad as WiFi... otherwise use a taskmanager and see who is using the CPU....shutdown all programs too when the phone is really not being used. I had the Wizard / Hermes and both were crummy on the batteries...
I do have to admit though that the Fuze does seem to consume more battery already....even though I know I play with it since it's new...lol

I charged the battery to full state around 5 times after I got it, thats not the prob. Beside: it shouldn't make a difference if you let it connected to the charger, its LiIon and not a NiCd-battery.
It can't be that the battery dies after 2 weeks of use, even in a worst-case scenario! If, HTC is ****ed.

As I said earlier, I had the HTC Tytn before, and it really had a standby-time of around 300hours, so if I didn't use it and just carried in my jacket and received here and there some messages or calls it lasted around 3-4 days.
But the TouchPro now only lasts 12 hours "just in my jacket"?? Hello?
And: yes UMTS(3G) makes the battery-time smaller, yup. But e.g. from 350hours to 300 hours, not from 350hours to 12! Even if a GPRS/3G connection is established, as long no data is transfered the connection should, beside some IP-data to keep the connection alive, not make a much less battery-life... again think about the 350hours.

yes, that sucks. i never had any GPRS/3G connection, just enabled and the phone was dead after 12 hours or even earlier.
but since i disabled UMTS my battery lasts a week and longer, im really happy with the device now (but its annoying that i have to enable 3G everytime i need it)

Well in my eyes it is not normal, or if then mis-manufactured stuff.
I would like to know where the difference between the TyTn and the TouchPro is (in case of the UMTS-part) if it was before possible to get a week standby-time and now it dies after a half day.
Oh and btw.: where can I turn off UMTS? In the tytn with Schaps ROM i could do it in the comm-manager.
In the TouchPro I only have buttons for Phone, Wifi, Bluetooth, Flightmode, and DirectPush (what I can't use... no idea how. Works only with MS Exchange-server, huh?)

I know that it says 300 hours, but you'd be foolish to actually expect that. Those conditions would be pretty much not touching the phone, with no programs running, no calls, texts, updates (e-mail, weather, etc), in order to acheive 300 hours.
I'm on a stock AT&T rom albeit with more tweaks than I could possibly imagine with moderate usage (a few phone calls, dozen or so texts, an hour or two of surfing, push e-mail on two accounts updated hourly, GPS for about an hour, maybe more that I can't think of) and I hit about two days.

If i was using all that stuff, theres no way i could get 2 days...im on a stock rom too but i get about one day, maybe its because i havent done any tweaks yet? any bettery tweaks or any other useful tweaks you could point me to? i kno i saw some around here but i tried searching and couldnt really find anything

Battery Life Diminishes with Cooked ROMs

Hello all,
I was wondering if there are any other S710 users who have been experiencing battery issues with the HTC Vox.
For a while I was running Dr. Gonzo's Guava Rom and everything was great with it all except for the battery life. I didn't pay much attention to it, but it finally got on my nerves. It came to the point where I could only use the phone for around 14-16 hours under moderate use and wifi+bt OFF after a full charge.
Today, I flashed the VOX with fireburned CLEAN v1.2. and it seems to be the same. I don't recall having this issue with the Official ROM.
Battery issue? any ideas? I dont want to spend money on an extended battery if it is a software issue.
Much appreciated!

It seems same to me too. I flashed not less than 20 ROMs in my VOX's use of nine months and I found that my battery slowly got weakened and was going only for 14 15 hours without too much use. Practically I had to buy a fresh battery from www.megacapacity.com. It arrived yesterday and serving me about 1.5 days for normal use. It is 1100mah in place of 1050mah original but is of std size.
Opinion of other users invited.

Did not notice anything as such. My Vox is nearly 1 Year 4 months old. So I am not expecting much from it.
Because during my initial flashing, I never had any noticeable battery performance issues. I have flashed almost all ROMs of Dr. G's, a couple of fh's and 3 of fireburned's ROM, about to flash with the 4th

I've had my phone for approximately the same amount of time and I've only flashed it probably 4-5 times in total.
Perhaps I shall look into getting a new battery as well...I want to be able to use Wifi normally without losing the phone halfway through the day.

I think you may have a hardware issue (not sure though). When I am not travelling, my phones battery at the end of the day shows more or less 60% charge left. I use flexmail to check my mails every hour. If there is any mail worth reading, then I use i.e. to check mails. So I think you can consider it moderate GPRS usage, plus there are of course voice calls . Though I do not use wifi or BT.
If you plan to buy a new battery though, I think it will be better if you go for an extended battery.

I read in another topic that it's somehow related to the Radio version.

Parthabhatta, what were shipping charges to india? how much is the total cost? How much time does it take in delivery?
i am looking to buy a new one same 1100mAh.

Because im new with Vox in generally can someone tell me what should be aproximated battery life with vox? (NO wifi, NO bt, 1-2h/day using normal phone calling)
What could be normal battery life with TCPMP and movie divx 320x240 256kbit ?

Everyone seems to have great battery life, so I wouldn't be the person to tell you what the average battery life is.
I just tested out the battery life this morning. 100% charged and i turned on Wifi to use. 45 minutes later, my phone dies.
So I get less than an hour of power on Wifi. I don't think that seems like a battery problem. Using it normally, gives me at least 14-15 hours+ (no wifi/no bt).
Perhaps its a hardware bug? Software bug? Any input is appreciated.

Hi gwmnx!
The same problem i have to, my battery life is very poor , maxim 10- 12 hours(no wifi/no bt), without browsing internet or other else and battery dies.
I buy a new battery, and exact same problem with it, in maximum 14 hours is finished
I was in a service , and they verify my batterys, and they told me the batterys is very good both.
And probably the phone have a hardware issue , but they don't know to repare it because they don't have a electronic schematic of my phone
I tested 3 ROM's by now, but nothing is change, with every ROM, same problem.
I don't know what to do and what to say, i'm very disappointed
Excuse me for bad English , i don't speak very well!

Same issue i am facing here. My phone battery dies in 10-12 hours. Don't know if it happens due to lot of ROM upgrades everyday or using overclocking...
I am going to purchase a new battery soon. If that also works same, i will revert to original VOX 6.0 ROM. No overlcoking, no R&D, no research no development further because you need to compromise with hardware malfuntioning, damages etc against this kind of R&D.

I bought my battery for 15.5$. Shipping is free worldwide on all items. It reached me in 16 days. It is now giving me 1.5 to 2 days on fireburned 1.2 ROM.

For a change, you just change the homescreen from sliding to anything like windows default. And make normal usage. I'm dead sure you'll get better results even if you're in Rose ROM. I mean, you'll get better battery performance if you're not in sliding homescreen.
I'm using Fireburned's 1.2 version ROM.
Thanks

How does the sliding panel attribute to 45 minutes of wifi usage. I'm not even on the homescreen, just using the web browser?
I mean, I think it might be a definite reason since I only started noticing poor battery life after 6.1. With the original Vox WM6.0, I definitely had better battery life.

there are some roms that kills the battery life to around half or more. like gonzo's latest rose rom.

Sorry skchattha! its for 18.5$and not 15.5$ (actually 15.5$ was for my nokia battery). I confused. Just go to the site and it will be clear. Actually I was charged Rs.948.00 in IndiaN Rupee.

Great man! Rs.948 is still cheaper, HTC service centre rates are Rs1390.
What do you mean by Extended battery? Any difference from normal battery?
And what about 2250mAh battery, does it fit fine or looks odd?

2250 mAh is the extended battery. I didnot buy although it was comparatively cheaper because to me it will not only look odd but make the phone bulky and heavier too. But now i feel that 2250 would have been a better choice as i am an avid gprs user. Now think and buy- difference of only 2.5/3 USD.

Well, being in browser doesn't mean your homescreen is off. Sliding panel itself consumes lots of battery. Just change your homescreen from settings to something else not related to sliding panel or Rose Homescreen. For a change just change it back to windows default. let it be changed for a day (You won't loose anything). I strongly believe there would be some difference in battery consumption and consumption will be lesser.
Thanks
Extended Battery really looks too odd. it looks like you've added another battery

Another my battery sucks thread!!

OK. I'm a week into my TP CDMA by Alltel. I have the GC ROM installed and am not using any of the TouchFlo stuff. I am using SPB/S2U2/Pocketalarm to get a decent setup. I have backed off my email to check once every 10 minutes for one account and only once every 4 hours for the other two.
I have the screen dimmed to almost unviewable, and screen blanks at 10 secs, no BT, no wifi. yet despite that, coming off a full charge this morning having sent 10 texts, checked 2 emails and NO internet NO phone calls. I'm at 62% at 10AM.
By the end of the day with ANY use I'll be dead. I'm coming from a MotoQ that I added the 2100Mah battery which lasted very well but not an option for this phone. Reading that GPS being on may impact the battery but I'm not seeing that the GPS stays on in any way I can determine.
What can I do this is horrible. other tweaks changes? carry another battery? Sucks to thin I'll have to carry a second battery just to make it through the day with minimal use.
Please advise. I like the phone but I just can't justify the abysmal battery life.

Im at 94% and I have been using fm radio for 1 1/2 hrs. I think your rom or radio has problems. If other users with same radio and rom dont have the same issue then get your phone replaced.

now at 54% done nothing except 2 more txt.
CDMA use more juice than GSM? (just wondering if comparing apples-apples).
Other CDMA ROMS that people are using with good radio/battery success?

i have the alltel stock rom and my battery is bad to, do the battery tweaks in the wiki help alot? mine isnt as bad as yours i can go to about midnight while sending quite a few texts and a small amount of internet.

You using the latest version of S2U2? I believe anything before 1.40 had a bug that was causing it to drain the battery fast.
Also, look at the S2U2 FAQ at the 8th question:
Q. S2U2 consumes a lot of power?!
A. Make sure there is no music player running in the background.
A. Don't use GIF wallpapers.
A. Don't use a folder of wallpapers.
A. Turn off "Show Appointment".
A. Turn off "Show Weather".
A. Turn on "Don't use Keyboard Hook".
A. Turn on "Ignore screen orientation"
A. If any "auto-rotation" application is installed, please add "S2U2" to it's exception list.
A. Turn on "Safe Mode".

That's atleast one place to start.

My phone just died too its 3:20PM, I took it off the charger this morning, checked a couple emails, then for the past 2 hours I have been chatting on IRC through DATA not Wifi, and the past hour ive been switching between Opera and zsIRC.... I also used the FM radio recently for about 10 mins to try it out... is this a lot of strain on the battery or should it last longer, I have the AT&T Fuze with stock rom.

Sometimes I think that there are people in this world (including myself) that suck the life out of batteries no matter what the device is.

My battery life was awful until I changed ROMs and radios.
Now. at around 3pm with fairly heavy use (msn on all day starting around 8am, texting, internet use) on any average day I have roughly 50% battery left with the 1500mAh battery from seidio, which is good enough for me.
the only thing is, I never use 3g as I have a euro raphael so I can only use edge.

Aren't you keeping your Data Connection on all day long? Try to do that on an iPhone. I only turn my Data Connection on when needed so the battery will last longer.

I'm with Alltel as well and mine can go about 8-10 hours with 10-15 texts, 10-20 minute calls, 5-10 emails.
Have you turned off auto update on the weather and windows updates. Also turn off location. (If you want GPS, then you need to turn it back on)

well, I have since reflashed to a new ROM and am having a much better response. getting much better battery but i also have the data connection off after 40 secs. I do have gps on but i thought it was only active when called by a program? ROM made biggest difference. still not 100% happy but getting better.

battery life. With which ROM they lives longest?

With Energy standart from 17Sep09- it took 5 hours until full discharge...

Impossible... check Radio or Rillphone...

my 16 sept 09 build need about 2 days to fully discharge..

what with u?

You cannot measure a ROM's battery life performance by installing a ROM and seeing how long it takes to die. The device needs time to calibrate. About 1 week of normal usage minimum. After I flash a ROM, I'll sometimes get 5-12 hours on the first charge. After a week I get typically 48-72 hours per charge. This is with screen at full brightness, 3g/data on, lots of txt and calls etc. This has been my experience with all of NRG's ROMs. I do install the recommended radio, no need to mess with rilphone.dll if you are using Energy ROMs with the recommended radio.

With TAEL rom and 1.11.25.01 I was at 71% after 3 days of liberal usage. I am trying NRGZ's latest build now but TAEL's ROM has been by FAR the best I have ever used. I haven't left NRGZ since I got my Fuze 6 months ago, and TAEL instantly switched me. Battery life is much better, the ROM is better in every category. I recommend TAEL, with ENERGYRom a close second.

I get exactly 24 hours from full charge to less than 10%.
3G always on
Data connection always on
a few phone calls, a few texts, light data usage (web, rss, email, maps)
Using latest EnergyROM
I can get 1.5~2 days maximum if I turn 3G off, data off, and further limit data usage.
This phone is just extra bad with battery life in general. Even with the stock ATT rom I wasn't able to get more than 2 days.

am I the only one that uses a cradle charger with an extra battery and not care about batt life.
I care more about the quality of the rom.

nah, I would also prefer a newer/better performing ROM at the expense of battery life (which isn't always the case). As long as it last me throughout the day im fine.

Battery life is also highly dependant on geography. When I'm in the country (with coverage at all) the battery runs much quicker.

These are all subjective matters and opinions. You can not compare the use that each one makes and where each one makes it. Too many variables. The time it takes to discharge does not mean anything, or it says very very little to the other person.
It would be interesting if someone conducted a benchmark with some metrics to evaluate what each ROM consumes and where does the power goes (which apps, backlight, ...).
Maybe one day we can have a standard benchmark, maybe a simple thing, which can be used by the chefs when they release their ROMs, or by someone else, and that gives results that we're able to compare.
Perhaps someone who is reading this, is willing take this challenge and develop such a benchmark. That would be great.

I generally get the same usage with 3G and Data set to "always on", gps daily and maps. I can go a full 24-36 hours routinely and over the weekend if i'm not on the phone a full two days. I'm a flash ***** so i've had this on several ROMS including Energy and NATF.
I always use the ril with the appropriate radio, but accidentally used the 1.12.25.19 ril with radio 1.14.25.35 with great success... In doing this I was getting super battery life immediately....
But at the end of the day you need to find what combo works for you, what may be great for me in Atlanta may totally suck butt in San Diego or anyplace else for that matter. So test test test and report back...

i can only suggest this: LevelSightSvc.1.0.3.2.CAB
http://forum.xda-developers.com/showthread.php?t=446434
install, go to power settings, disable SO auto adjust, and set the slider in the position u like (i usually set the 3rd step from the left).
LevelSightSvc fully replace the system autolight with HUGE improvement of my battery life.
Try it.

There are lots of things to take into account with battery life. Your radio can play a huge role as well as the base build the rom was built on. Then the various settings and apps suckle the battery tit also.
I put my phone on a charger every night before I go to bed since I use it as an alarm clock too. I usually have 60-70% left over with some light GPS, full brightness, a dozen texts and 5-6 calls. I don't know how accurate that is since I'm a chef and flash my phone 5-6 times a day. The latest one I've used for a while and seems nice.

there's a prog from nueROM called nueDynamicClock which underclocks your cpu when it's on standby or when the screen is off. it will increase your batt life significantly if your phone is on standby for long periods of time..

I agree with some of the others.
I am currently using EnergyRom Genesis build 09-20-09 (1.14.25.05 radio) and my battery doesn't run out that quickly. I recently did a stress test (as a comparison to a Nokia E71 I own) and the phone went roughly 5 hours before it hit 10%.
However, take my usage into consideration:
1) 3G always on
2) Heavy data usage (Youtube, Internet Radio, web surfing, etc)
3) Receiving text and emails
Obviously, that is very heavy usage, and will naturally drain the battery, but it took five hours to do so. By comparison, if I had just use it normally, it would last roughly 1.5 days.

Samsung Captivate on the Quest for the Greatest Battery Life!

I'd love to hear how people are finding the battery life on the Captivate, and what their usage patterns are. I don't have many apps on the phone to begin with, but on the train to work I can easily knock out a third of the battery just listening to music. While using the phone for five or ten minutes, I'll sometimes see the battery dop 2-3 percent!
For tomorrow, I'm going to try using the stock launcher instead of LauncherPro, no widgets. I got rid of the Android Central app just in case it was fetching data in the background. But my hopes aren't terribly high, I'm afraid.
I have rooted the phone, but the battery life was bad before rooting. Once rooted, I tried some apps like JuiceDefender, and there seemed to be no change.
If I continue having these problems, I may unroot and bring the phone to an AT&T store to see what they say. I've heard it mentioned that Samsung is sending out new batteries that are better than some current ones, but I don't know if that's true.
I'd love to hear any suggestions. I want to use my new phone, not worry about it all day!

I too have been getting very poor results. I have talked on the phone for less than 3 minutes, went to maybe 15 different website pages, one 3:00 youtube video, 10 minutes of GBC emulation gaming, and regular texting, and I'm at 10% with 8 hours. I've probably only used the phone for 30 minutes total today.

Smartphones always drain battery, if you want a phone that can be heavily used for like 4 or more days on one charge cycle, get a feature phone....the samsung captivate has given me the best battery time overall, against all my past smartphones.

I don't think it makes sense, though, that it should run out halfway through the day like mine is. My former devices were a feature phone and an iPod Touch. The feature phone lasted a week or so, and the iPod Touch with heavy heavy use lasted three days at least. So even if I had both pulling from the same battery source, and with light usage, shouldn't it last at least a full day?

Weird, I had wireless on almost all day, with push mail and doing tons of market downloading and I was only down to about 50% by early afternoon.
Seems about the same as my two year old HTC Touch Pro to me.

My battery is running fine too, even after streaming music from my house with subsonic, testing out a couple videos, messing with the gps, push email a bunch of app downloading, and a live wallpaper and i was still at 33% by the time I got home, even seems to be getting better.

There's a bit of your problem, methinks. The 3G radio is burning a lot of power trying to connect to towers inside a metal box that moves to a new tower on a regular basis. Unless you need to get calls on the train, put it in Airplane mode during your commute.
Have you actually let the battery die completely yet?
My first battery burn-down, (starting with the charge on the battery as it was unboxed) I was showing zero percent battery for almost two hours before it actually shut itself off, moderate usage with WiFi on.
The next charge-up burn-down, it was showing zero percent about fifteen minutes before the end.
And the charge-up burn-down after that, it showed 0% about twenty seconds before it died.
See where I'm going here? The software needs to be calibrated at zero and 100, and it can't do that if you don't let it reach zero a few times. Once you're sure the meter is accurate, then you can start making informed conclusions about battery life.
And like I've posted elsewhere, you've got 'Newshiny-itus', which is proven to suck extra life out of a smartphone battery. And it's hard forcing your new toy to die...for one thing, if it's dead, you can't play with it. Tough it out, kill it. At least twice.

Well if you want to find truly terrible battery life try the EVO.
I had one for a month and that thing really ate the battery fast. The capti is stellar in comparison.

Yea I had one for two weeks and it was horrid. I would lose 6% just in standby time in between waking up and getting out the door to work in the morning!

I've had great results with the battery and I find it to be much better than my HD2. I watch quite a bit of youtube, text message a lot, and browse the web and the market on and off, not to mention all the time my wife plays solitaire, and I still have 30% battery at an uptime of 41:46. I don't use gps or live wallpapers, and I keep my display as low as possible, since it is still bright.

Bit better by the end of the day. 13 hours and 15 minutes

Definitely agree with the last part. I've been doing my best to kill it, but I don't want it to be dead. Been noticing the inaccuracy of the meter quite a bit, especially when it's charging, but I'm sure it'll get better over time.

Thanks for the informative replies! It hadn't occurred to me that the battery meter might be uncalibrated - I've been charging once it reached 10% or so. I'll try letting it die fully today.
One thing that seems to have helped, too, is the brightness settings. Turning OFF the "power saving" auto adjust ing brightness option allows the brightness to stay low, and a brightness control widget lets me set it lower than stock controls allow. I've seen some definite improbement from this alone!

These are Li-ion batteries, DO NOT let them die completely before charging.

Ok, so...is there a safer way to make sure the battery gets calibrated? I'm reading in a lot of places that Android phones fairly often misreport battery info unless calibrated.

The lowest I can get on battery status is 60% after a full days use. Admittedly I'm not a power user but I had my phone unplugged for 16 hrs and still had 95% I'd like to know what you have to do to get such low battery levels , start your car

All I've done today is listen to music for an hour (used 25%) and texted/browsed the web for perhaps two hours (another 5/% down.)
I read that LIons can be occasiomally discharged, since they have undercurrent protection circuits. One guide for Android phones suggested leaving the phone on until it shuts itself down, turning it on again, and then letting it shut itself down again. Then, with the phone off, charge fully. The guide said once a month or do is safe and beneficial. How does it sound?

Battery is good today. Been sending a few texts, checked email, facebook, and surfed these forums a bit. I'm at 2 hours with 98% battery left.

i hope the battery doesnt suck, i plan on getting this phone soon and want good batt life!!!

I agree with you, however, the phone's hardware will NOT let the battery completely die.
So I wouldn't worry about that all to much.
Basically though, Li-ion batteries are 'memory' free so they can be recharged on a whim partially.
They also prefer partial charges vs deep charges.
There are questions about this that I don't have answers for such as: When the phone displays 0% or shuts off due to low battery, how LOW is the battery?
Obviously the phone battery can't be dead dead, but it is low enough for the hardware to take precautions.
Anyway Li-ions will at max last 500 charges.. If you want it more than that, You're going to have to buy a new battery anyway. =)
