Battery lifetime

Hello.
I own a Htc Advantage with WM6.
Ive been noticing that at dinner time my battery is low.
I have BT always on and backlight at mximum but since Im in holidays I barely use GPS and phone.
Is it normal? Does it happen to you?
Best regards

I also find battery life inadequeate for my use (but I must admit that I'm too addicted to this device, so I use it almost non stop throughout the day - as long as I'm not doing other things that is).
I solve this problem by buying a second battery. However, even the second one could not last till the end of the day. I store all application in my MD at the moment (long story on this, but I might shift it back to SD card later), so it consumes more battery as a result.
Carrying the second battery is no problem since it is so thin and tiny. Just put it in the pocket.
I got mine from ebay, shipped out of Hong Kong. It's really cheap, and has a one year warranty.
Hope this helps.

Thanks for you reply.
Any other opinions?
I was afraid that mine had a problem, but perhaps thats a commum problem, right?
How do you solve it?
Best regards

If you have your LCD brightness on maximum it will quickly drain your battery. Lower it. Maybe half way? I have mine set at the 4th lowest setting. It is good enough for indoor use, and if I need to use it outdoors, which is fairly seldom, I just set it higher.
All day usage (12 hours), with a lot of GPRS and phone calls etc. my battery goes to about 50-60%.

I used to have much better battery life -- could go a whole day and still have 30% left. When I switched to AT&T, battery life seems much worse. I was on T-Mobile. Upgrading to WM6 seems to have made things even worse. Any solutions?

one observation on the x7501's, if you have ANY meters on (today screen- ilaunch, spb etc) it will make a big draw on the power, have seen it drop 30-40% overnight (while off)
turning off the meters (still running ilauncher, just no meters), and much better battery life.

Crappy battery life on ATT 8525

I have a slight beef about my 8525. Sure, it's a great phone with a lot of features, but that only goes so far when the battery life is terrible. I came from a RAZR so maybe I am expecting too much, but I can start the day with 70% battery life and take a couple pictures and browse the Internet for a few minutes (under 10) and end up with 40% battery life by the end of the day. I'm not keeping Bluetooth, WiFi or any Cingular connection open and I am leaving the phone in standby. It seems like anytime I do anything, the battery life goes down 10%. The only software I have installed is Google Maps mobile. Is this normal or am I expection too much out of this thing?
I have done the registry edits for better battery life and conditioned the battery properly when I got it. Will a different radio version help (I currently have 1.40.30.00 on WM5) or WM6 help?
I once placed a 45 minute call and the battery life went down 20% just by doing that.
Am I being too picky?

I've seen people say that some radio's gulp power like crazy, so u cud experiment with different radio's.
I'm on 1.47 rite now and I talk a lot of my phone, use google maps, browse the web, and I charge my phone once every 2 days or so. So its pretty good, i think for the amount of functions the phone has.

I just did a search for battery just in this forum, and in the title of the thread and found a lot of similar complaints so I don't feel so bad now. I also did the registry edit that allows the BAND tab to show under the PHONE settings so I can manually lock my phone to EDGE most of the time and select UMTS only when I prefer the additional speed. One would logically conclude that locking the band would help battery life. We shall see
Radio 1.40.30.00 seems to be a radio version most people are content with so I am stick with it for the time being.

Battery Life
I had an 8125 for almost a year and it was usually good for a day or so.
I recently dropped the 8125 into a cup of water... Amazingly it was not submersible. So now I have the 8525 here in Los Angeles.
The battery life is pretty pathetic. If I unplug the phone in the morning (around 10am) and just carry it around with me without even talking by 2am the phone is letting me know the battery is low.
If I talk on the phone (under an hour) then the phone is dead by 11pm
I use Google Maps for the traffic, and I also have multiple exchange email accounts which check about every 10 minutes.
On days when I actually use the phone and google maps, if I unplug at 10am the phone is dead by 6pm.
At the moment I am running Schnaps 3.60a.

*All* PocketPC phones will have battery life about as long as yours has.
The problem here is merely that you are trying to compare its battery life to a normal cell phone. For the past 4-5 years, the battery life on Windows PocketPC phones has been about the same.
If you want to compare your PocketPC to another device with regard to battery life, you have to compare it to a laptop and not a cell phone.

Welcome to the future.

I do realize that all of the advanced features will use more juice. I use a HP iPAQ and a Dell Axim at work which both use WM5 and those only get around 4-5 hours of life before they are dead.
It just seems that battery technology is lagging behind the electronic gadgets that use them.
I almost hate leaving the house with the phone being less that fully charged in case I really need it somewhere I am not around a place it can be charged. Suppose a car charger would be in order.

Yes! Crappy Battery Life on the 8525
Yes. I came from an 8125 (ActiveSync on 25/7) and was able to use my phone for 1.5 days. With the 8525, I am lucky to get 6-8 hours. Big bummer!

I locked my 8525 into the Edge network and I believe that my battery life has increased marginally. Of course, this will not work for some people because they need the faster 3G network, but if you would rather have longer battery life, I say give this trick a try. It is really nice if you live in a fringe area where your phone bounces from Edge to 3G and back again frequently.

Sorry but you are totaly wrong.
I had a TyTN for 3 monthes. I hardly had more than 24h in standby (no phone, wifi & Co). Phone was only in GSM mode, no UMTS. Tryed a lot of rom/radios.
I sold it, cause this was really too ridiculous.
Now I own a HTC Touch. With same usage and applications installed, I charge my phone only every 4 to 5 days.
12h in standby = only 10% less for battery.
This added to form factor made me very happy, no way I come back to hermes or even kaiser ...

hello. i have a huge dillema. i was using my touch hd to browse a few webpages for 5 min. next thing i knew i had loss 10% battery. have any of you experienced such a huge battery drain before? o.o

Having wifi/bluetooth/GPS etc all cause bad battery drain and can cause drain like you described depending on which rom you have installed and which apps you have on your device. Also disabling 'incoming beams' in settings also helps improve battery.
Do a search for 'battery' and you will find numerous threads on battery drain and causes.
Also check to make sure you have no apps running in the background which may add to your drain.

thank you fallen spartan. responding to your post, i am using dutty 3.3 xt rom and it absolutely kills battery, even listen to music for an hour already drains 20% if i actually use my phone to watch a 60 min of videos, 2 hours of music, and play 5-10 min of teeter, my phone does not even last the day. not even close to it. i cant really find an answer looking at other threads cuz they r way worse than my issue. but still for a high-end device like this to have this low of battery life frustrates the hell out of me

Craz,
Well, the thing is, battery technology is the slowest improving tech compared to every other hardware piece in mobile technology. There are definitely much better forms of battery technology, but there is still a while before it even reaches us consumers.
Cheers.

WIFI drains battery fast unless you select best battery mode (maximum power save) and got it mostly idle, messenger or light websurfing doesnt drain the battery has fast has streaming music or downloading some files. The drain caused by heavy wifi use also harms to much the device thus reducing his life and mostly killing the battery much faster. It's just the way things work, don't blame the device for it because it's the same on all devices.

Don't blame battery technology, wifi wastes to much power in form of heat and most of the time they are using to much power than they need to send the signals, they should be more energy efficient.

Another battery problem

Hi all
I'm a new member.
Great forum I have to say
I have a new battery after the old one started draining itself
in under a day, no problems before that, the new battery is doing the same,
I have the phone set to "turn off power if not used for 3 mins" &
running window mobile 6.5 test (before I ran windows 6)
I'm just using it as a phone really & not much else, can't figure out
why it's draining the battery so fast!
yesterday it told me the battery was really low but I left it
for around 10 hours & it was still on but had the same low power level
as the day before
any help is appreciated.

I'm also interested in that. I have a 2+ year old battery, and now with 3g it lasts 30 minutes if browsing full....
thanks!
PS: sparks72, how long does the new battery work? what are the specs of the battery?

Hi diegolaz
Battery drains from 99% when fully charged to 80% in a few seconds!
can last all day if handset isn't used but after only a couple of short calls drains dramatically & nags me for a recharge.
The new battery is a 3.7V DC Li-ion 1350mAh.
manufacturer is Celxpert Energy CO Ltd. (China)

Strangely I've been having battery drain problems too, most notably when using 3g data or wifi. Thing is I do have 2 batteries to test with and one of them is not very old. I'm running radio 1.54.07.00 which I have been using for a long time, long enough to remember not having problems with it.
I started keeping a log, here is my results for today:
3:26pm, batter starts at 79%
4:40pm = 71%
8:30pm = 51%
9:30pm = 19%
Between 8:30 and 9:30 i did a hard reset, installed some apps, used wifi for a bit to download the apps and get my exchange account setup, and got/sent some text messages. Seems like a pretty huge drop.
Does anyone know of an app that can report current power drain on the Hermes. I remember having something like that for my 8125
Today I just ordered a new OEM battery off of ebay for cheap just to see if it makes any difference, I recommend you all to do the same. It's the first step of the process of elimination....maybe both batteries I have really are bunk...or that i'm spoiled on my TILT's battery life.

Also turn off "beam" that seems to be on by default.

using wifi will drain the battery pretty fast anyway, but i would also check that your rom is not activating wifi on the sly, i had it when i cooked a rom using josh's kitchen and thought it was my battery that was knackered, turned out it was the wifi switching on constantly ,but i had no indication it was on. Not saying that is your problem , but worth checking all the same

Nothing is on in the background.
Battery still draining fast

The battery problem for me happened when I upgraded from WM5 to WM6,
even though I have had my Hermes since 2007 (brand new) I only started using it in Feb 2009. (had enough phones to deal with!!)
I tested my old OEM battery & their doesn't seem to be anything wrong with it, very confusing.

Well i got the new battery in, and in 24 hours i went from 96% to 8% at a drain rate of 3.66% an hour. This is good news, I guess those two other batteries I have are wasted :-/ , but at least the TYTN is ok.

I am also facing the exact problem. But I don't think if it is the problem of battery. I think it's some problem with ROM version..
Any help is appriciated.

I have tried several different ROMs but the battery still drains quickly.

Can anyone on this forum shed some light on this problem at all ?
Have any of the developers experienced battery drain problems ?
Does anyone have a solution ?
Thank's

For how long D2 battery lasts?

Hi,
I have diamond, and thinking to get diamond2.
I have a question for D2 owners.
How is the battery life on D2, because the original battery for D1 was terrible, I got the extendet one so it's ok. But as I know there is no extendet battery for D2. And the stock one is just a bit bigger then D1. But the screen is also bigger on D2, with drains more battery, I think.
How long the phone lasts with moderate use? Also is there a difference with 6.1 and 6.5.1 rom with battery drainage?
And maybe someone had D1 and now hase D2, so whats the + and - compared?
Thanks

I have had both. The TD2's battery is considerably better than the TD(1) in my opinion. I'd say the TD2 would be at about 30-40% charge once the TD(1) run out.

I think my TD2's battery is pretty good, as long as 3G and bluetooth are turned off. Other than that: abysmal (Not quite TD1 bad, but almost)

I'm getting around 90 hours. I recharge when the battery reaches 40%-50%. Generally bluetooth, wifi, and cellphone radios are turned off. I use my TD2 as PDA.

I find the D2 battery life on WM6.5 much improved. I seemed to be always charging it but now, it's less critical. Also, with all transmitters turned off, the lifetime is pretty good. My phone was on for a week on holiday and the battery was 90% by the end of the week having turned the mobile on for an hour or so to check messages a couple of times.
Of course, turning the phone & WiFi off isn't very practical but it does shown where the power drain comes from - no surprises there!
Cheers, Rob.

am getting 2 days , to 3 ...normal usage, and songs.

got even 4 days with normal usage. Can always buy a bigger battery

My wife got a TD2, and battery lasts for 3-4 days with her usage, and when I used her phone it lasts about 2 days. Not too bad, really.

The longer you have the TD2, the less you "play" with it and therefore the better the battery becomes. Never base battery consumption in the first month of getting your new toy
Cheers, Rob.

On ROM Base 2.18 drained for couple hour.
On 2.16 go 3-4 days with normal usage...
Regards

I have Duty HG R6 and battery drains FAST! Fully charged it lasts less than a day with normal usage on 2G network and everything turned off (BT, WF), few messages and max 2 hours of talking! And one more thing, anyone else experiencing that phone is getting hotter after 5-10 minutes of talking? Sometimes I cant put it on ear because of that...

Same here, 2 hours of talking and battery are gone, all other (BT, Wifi, 3G) are off, no play with device, only talking and some short e-mail read or write.
I search this forum and all users write that device last for 3-4 day ?? But what usage are to last 3-4 day, my phone is empty on half of working day.
And yes, phone are hot after 10-20 minutes of talking, some time my call last for 50-60 minutes, and this is terrible, like radiator on ear.
My call consumes eta 1% for 1 minute of call, (13 minutes , battery drops 11-12%)
Is this normal for this device, i have no answer on this question, but i plan send device to HTC service, because 5 h of talking in specification are far away in my Diamond2.

Maybe we should try some rom with 2.16 base and not 2.18 like miro666 sad. Will try it soon and report than and I'm using 4.49.25.14 radio...

I always have everything switched on with wifi and data access available when needed.
I run a 'lite' ROM, always install all apps to phone mem (Micro SD usage consumes a lot of power) and charge as often as possible.
I am probably what you would describe as a heavy user. I always carry a spare battery and an external power pack.
I need the extra power only rarely and so I usually make it throught an eight hour day on phone power alone with this usage.

Only a Day
I have a standard TD2 with a standard UK 6.5 upgrade.
Battery beeds charging daily. Im not even a heavy user. I make/receive a few calls, send a few texts, check my email and use "Brain Trainer" game for 15mins whilst on the bus going home from work.
The battery is pants!!
