Hi,
I have a very recently purchased XDA II.
I was under the impression that the battery time was considerably improved.
Although I have turned down the backlight brightness when on battery power, it still starts to loose power when I receive or send a SMS for example.
Is this normal or do I have a duff battery ?
Steve
try turning off bluetooth when you dont use it
it's suppose to be a batt hog
Yup,
done that. I only have BT on when I am actually using my headset.
Any other idea's
Steve
when does it auto turn off ?
when does the backlight turn off ?
are there any SD cards connected seem to recall that they eat batt aswell
I've had mine a week, have the same power drain problem. After charging it all last night I managed to use it as a PDA for a total of 40 mins over a 6 hour period today before the battery drained. No phone calls were made, Bluetooth disconnected (I do have a 256 MB card installed, but I don't know if this has anything to do with it), furthermore the backlight is set to the default setting and the auto power off set to 1 min. In any case I would expect to get more than 40 mins use of the PDA, the specification states upto 15 hours.
I took the unit back to the store, they say that this is a rare problem (yeah right :roll: ), they gave me a new battery which I am now recharging, hopefully this will work.
mmmm, it's very strange.
I am doing a test now. I have a imate with the official imate upgrade. I have a gps sysonchip bt. One and half hours ago i connected the imate with the gps and i started a demo of 500 km. Now the battery is at 75%.....Maybe de last upgrade solved this problem.... :shock:
You should get far better performance than this.
Three things that can drain the power:
Communications/Peripherals - IR, bluetooth, SDIO wireless LAN etc. Disable all of them unless you're actually using them.
Processor hungry programs - check if you have anything running in the background that could prevent the device switching to full sleep mode.
Lack of radio signal - if you're out of contact with a base station, the device tries to connect at full power every 30s - a big battery drain, so if you know you're out of contact, turn off the radio.
However, even with everything running, I'd expect a running time way above 40mins, so it sounds like you have a hardware problem with your device. I easily get 3h full brightness, full processing (ie watching a movie or playing a game) with radio on.
Turn IR off?
Is there anyway to actually turn the IR off on the XDA II?
Just the Start-Settings-Connections-Beam-Receive all incoming beams checkbox.
tried the new battery today, same procedure as yesterday (no bluetooth etc), had a slightly better performance today from the new battery, managed to get roughly an hours actual use out of the PDA (games etc) over a period of... 10 hours, ooh atleast it lasted the working day so must be better... however still no way near the 15 hours PDA work time as stated on the box!
However something I have noticed is that every now and then (after switching off the unit and just leaving it on the desk) the screen comes to life displaying a running program, (just how do you turn off the media player? I now realise it isnt with the "X"). Anyway why does it "power" back up? I wonder if this has anything to do with my power problem, that perhaps it has switched back on whilst in my pocket (BTW I have set the buttons so that they do not switch the PDA on accidently)
So, I'm recharging again, (I think I might take the MMC card out see if tht makes a difference). I expect something better for my EUR 500, what is the point of being able to go online anywhere if you have to be plugged into the mains! If I can't get the damn thing to work satisfactoraily by next week then it is going back to the shop, despite it being a Gucci shiny piece of kit!
@MoistVelvet: Actually, it;s not so much the device itself but the operating systems that is the cause of a few quirks. Luckily, a lot has been written on this forum and other forums on websites such as www.ppcw.net. A lot can been improved by limiting the number of programs that can be found in the \windows\startup folder of the XDA II. I'd suggest you have a look around in the various topics. I ended up honing my XDA II to a point where I am actually very very satisfied with it's performance ...
Can someone repost the items in the windows start up folder than can be deleted and what they do on the XDA II.
I was surprised at the amount of apps in there, but dont know what I can safely delete.
Steve
Wiz,
thanks for the tip, I'll have a look around.
Well the batery did last longer yesterday, managed to get through a whole workig day before it ran out, so the jury is still out!
Realised perhaps one of the reasons why the unit would switch itself on, whilst at work I have a very low signal, so every minute or two the signal strength would go up and switch the screen on. I have set to auto switch off after 1 min, but I wonder if there is there a way to stop it from switching on?
Hm, my experience is quite different. I use it throughout the day with around 15 phone calls, at least 2 GPRS synchronisations, some other usage of contacts, calendar and email and when I get home it's still around 60 percent - the most drain appears to happen on the way back home when I use the BT headset...
When your uses so much more power you may like to check what kind of programs you use. First idea is to have a critical look at fancy today plugins... my worst experience was with Battery Pack, the best way to empty your battery :lol:
Maybe you like to use UpTime plugin (http://ae.inc.ru/uptime_t.html) which really tells you how much you actually use the PocketPC and which doesn't do anythings while it's switched off...

Actually, the reason it periodically switches on is the O2 Homezone application. Whenever your phone changes to a new base station (which can happen even if you don't move), the stupid Homezone app turns the phone on. This is a known issue, and the only known remedy is to disable the app completely (remove from Autostart folder, soft reset phone).

Hi
I have an xdaII, which i load loads and loads of things onto. I did find that the battery was draining quite quickly. eg. charge it all night, just leaving it running in the day with hardly any use would drain the battery by about 90 percent! Bluetooth was off etc.
One time, the thing drained completely, and it needed a hardboot. Im going to send it back shortly for investigation/repairs.
However, since it hardbooted, i have not installed a thing. And i am finding that the battery is lasting a lot longer. I managed to go 3 days, of average usage, (few incoming/outgoing calls), without charging the battery!
This makes me think some apps must cause the battery to drain. I had battery app installed (that runs in today screen). I had fonix voicedial installed. I had quite a few games installed.
I think some software was causing the battery consumption,.. possibly battery pack.
re
I have previously had problems with battery drain, due to apps running in the background.
I also found specific apps like the battery pack, LAN sdio, bluetooth and the camera app, would drain the battery quickly.
Although you can manage closing apps down through settings/system/memory/running programmes I found the app Gigatask http://gigatask.com/ a simpler way to manage tasks.
There are others, but I found this suitable for my needs.
Now when I close an app I know it's closed and not running in the background draining the battery.
I still charge daily, habit now when I get home from work, but I have no worries about battery drain, and it rarely goes lower than 65% for a normal days use.
Cheers, Shire
turning infrared beam recieve off will help a little

Hi All - Did a search but couldn't find much about any 'battery life' problems with this device.
I'm experiencing poor battery life on my new XDA IIi. This is my second machine (o2 replaced the forst one due to poor battery lifery life and dead pixels on screen)
I just wondered what others are experiencing...I tend to have the phone switched from 8am til 6pm. The signal strength is good and I have wifi and bluetooth turned off.
Here is a typical set of figures for the battery through the course of my typical day
8am 100%
9am 84%
10am 75%
11am 61%
12am 50%
1pm 41%
2pm 32%
3pm 19%
4pm 11%
5pm 6%
6pm 3%
O2 say that the battery is at fault...but they've changed the battery twice and the unit once, and it's much the same. My guess is that something is draining the battery, but there's nothing special about my set up as far as I know. it's running a 1 gig SD card...but I took that out to see if it made a difference - it doesn't
Even with the phone switched OFF for extended periods of time, the battery doesn't seem to survive the day - I certainly cannot get to 8pm in the evening without having to charge it up.
I just wonder if the behaviour is fairly normal! If someone else out there is able to offer me some advice, or better still, some comparable figures, that would be helpful - just so I know it's not just me!!! ))
Alternatively has any one got any suggestiosn as to what might be draining the battery? (I'm always in a strong signal area for the phone)
Thanks
Hi I also have an XDAIIi.
My battery seems to be a lot more stronger than yours :?
If I don't use my XDAIIi at all, it can last about 4 days on standby, by this I mean phone on, wi-fi and bluetooth off. I have installed a LOT of applications on it and nothing seems to drain the battery.
My backlight is on full, my SD Card is always in.
If I use the phone say for about 30 minutes every night, then it lasts for about 3 days, still as the set-up above.
I find that if I am constantly using it, it will last about a day.
I am probably being pedantic, but as you probably know, rechagable batteries, in particular Li-Ion. Then they benefit from being run-down completely and leaving dis-charged for about 12 hours, then trying to turn them on again, (i.e. soft re-set) and then leaving them to turn off (almost instantly) Then whilst the XDAIIi is in it's "dead state" put it on charge using the mains charger and leaving it charging for about 3-4 hours. Then take it off charge and turn it on again.
Batteries don't like being half charged then run down a little then charger again.
Also the complete run-down time of a battery will only reach it's fullest after a couple of run-down and full re-charges.
This is what I do.
Hope it helps.
lydiachris
ps. the strenth of your signal should not make any difference. I am also in a strong signal area.
Battery...
Wow! Yours seems much better than mine with batteries. I just can't figure out what's wrong here and its very frsustrating - new battery..new XDA2i seems to make no difference, so it MUST be something I'm running...but there's nothing running in the background at all...very strange
Thanks anyway..at least I know it IS possible to get better battery life
S
Just out of interest, what mAh is your battery which came with your XDAIIi.
Mine is the standard 1300mAh
Lydiachris
ps. write me a list of what software you are running.
pps. Kettering??? Very near me Peterborough!!!
Battery woes...
MIne came with a 1300...but I bought a spare via the O2 shop that came with a 1200 :?:
I've got hundreds of progs on the XDA. Do you mean a list of ones that are running on startup?
Thanks
PS USed to live in Werrington!
do you have bluetooth or wifi or both turned on all day ?
is the pda on all the time or off and only the phone on ?
is gprs turned on all day ?
IR is it set to recieve all incomming beams?
how long before the backlight turn itself off ?
how bright is the backlight set to be ?
many many factors
Battery troubles
do you have bluetooth or wifi or both turned on all day ?
Both OFF
is the pda on all the time or off and only the phone on ?
Phone scheduled to be ON between 9 and 7pm
is gprs turned on all day ?
..Nope
IR is it set to recieve all incomming beams?
..Nope it's Off
how long before the backlight turn itself off ?
..1 minute
how bright is the backlight set to be ?
..about as low as it can go :lol:
As you can see, I've switched OFF most things to get drainage down to a minimum. As this is my SECOND device (o2 replaced the first one - same problem) and I'm trying out a second battery...my deduction is that it *MUST* be software related. I may be wrong and I'm hoping someone can point me in a different/new direction
I had a lot of hair when I bough this device - now I've very little left :wink:
Make sure lock all buttons is engaged, second set turn lcd off after 30 sec, third turn off device after 1 minute and you should be dialed in. If this does not work, preform a hard reset then repeat process. Do not install any additional apps/progs! Now if it works try installing one proggy at a time and test the device. It is most likley that there is a program running a daemon that is killing your XDA-IIi
Mikee
One more note. If you do a hard reset, which if I where you, I would, pay attention to the setup screen on the hard reset. When you see the O2 personal user corporate user screen, preform a soft reset with your stylus immediately! Then you will not get the O2 garbage and Icons.

hi
just got a xda2i and my battery doesent last long also my car phone charger wont charge it up quickly enough when its being used i took loads of stuff of but no difference.
regards kevin
Thanks Mikee
Hi Mikee
Thanks for your advice. I'm a little uinlcelar how a hard reset will help. This is NEW machine, I only got it last week. How does a HARD reset help the bettery management?
Make sure lock all buttons is engaged,
Done
second set turn lcd off after 30 sec,
Done
third turn off device after 1 minute
Already switches off after a minute
and you should be dialed in.
ehhh?
not sure what you mean

There is a fault with your device - under Consumer Service Guarentee you can return and have it replaced immediately as these goods are definetly NOT fit for purpose.
Mind you, you should hard-reset and double-check, but I'd say you've got a lemon flavour there.
Tkae heart, if you're the only one then it should be easy to fix!
My XDA ws the same when i first got it ... i'd deffo agree that the battery needs to be "optimised"
after a week or so you should notice a difference.
Heavy use of mine, ie listening to ,mp3s all day will take it down to about 15% (9 till 4 ish)
I have WIFI , bluetooth off
screen to the lowest brightness
power off after 30 seconds
[edit]
I just thought ..... You dont have the "Turbo mode" on do you ?
Battery on XDAIIi
Hi Guys - Thanks for your advice. What I find hard to believe is that this is the SECOND device where the battery life is c***. All my instincts tell me it's NOT the device - this is the second one they've sent me - nor the battery (as I'm now on my THIRD one)
I really want to avoid a hard reset because of the time taken to reinstal everything afterwards. I lead a very busy business life :? , and I just don't have the time to 'start from scratch'
...but I guess I will, if enough people tell me a hard reset will sort it :wink:
i did a hard reset but it didnt make a difference and when i spoke to 02 they were very quick to exchange it and when i spoke to the guy he said i should expect it to crash every so often like windows does on a computer i disagreed with this abd explained my xda2sw didnt crash like this one did.
regards kevin
stevep, in that case why don't u just make a complete backup of ur IIi, then perform a hard reset..
Sometimes the apps installed are the cause.. Also take note that switching to 'Turbo Mode' all the time will drain the batt pretty fast..
Battery drain - hard reset
Thanks for your reply - it's appreciated...but I don't understand how a hard reset helps. Yes, I can back it all and restore it, but surely that'll just put the problem back on the XDA (if it's an app thats causing the drain) :wink:
Can anyone explain (from a techy point of view) how a hard reset MIGHT corrrect the battery drain problem :shock:
Have you checked your turbo button under start, settings, power and then the processor speed? if you set it on turbo, it will eat up the battery VERY FAST. If else, I am using one and I am Happy with the battery life.
I've actually tested it with turbo 'on' and 'off' and I didn't notice much difference either way. It's actually on 'standard' currently

i bought my phone in june and i was little bit angry to see, that the battery lasts only one day by normal using it without bt, wlan and gps only sometimes internet and phone. i went to my vendor and it was sent to htc 3 times to get it repaired back, but it still exists the battery problem. now i read, that some roms are less battery catcher than other. which rom is good for saaving battery life.
thank you very much or are there other tricks to improve battery life.

TC,
Are you using stock ROM or..? I've not change my phone's ROM yet and even until today, I get 3 days worth of normal usage (I charge my phone at about 20 ~ 35% range depending). I don't use it much for anything except being a phone, occasional web surfer, and very very importantly, an organizer/calender.
Also, do you leave applications running in the background? Do you close all of em? What is your brightness setting? How long does it take for your phone to dim the screen? Since I don't really care for 3G and HSDPA (couldn't even if I could), did you set it to GSM only? Do you turn off your phone module in signals with very low bars?
My point is, a lot of factors can affect battery drain, I hope the questions I've asked might help you better pinpoint what the problem seem to be. I wouldn't be surprised if the drain is due to the phone being in a constant 0 ~ 2 bar zone.
Cheers.
hello ,
thanks for writing back so fast
no i didn´t change or updated my rom with any roms which are able to be downloaded here. my phone was updatet when i brought it for analyzing in the htc shop.
i charge it always when it has nearly nothing anymore.
i use it for the same reasons you need. i use 3g because it was written, that gsm uses more battery than 3g
i always push down programs in the background only activesync is not easy to close
...... Do you turn off your phone module in signals with very low bars?
that i don´t know what you mean by "in signals with very low bars"
i also use mort player an windows player and by using these programs the battery drains a lot
thanks
dietmar
Hi friends
i find out that my HD2 use 3% battery in 1Hr in standby mode (not using phone) (in GSM mode)
PLZ test ur battery usage (example leave ur phone for 2Hr and see the usage) and say result in this topic.

Hmm, Why?
Hi Wizard,
What are you hoping to achieve here?
Battery usage is a complicated scenario. Even in sleep mode your device is doing things in the background e.g listening for SMS & Emails, attentive to Exchange Server requests, dealing with items in the notification queue, etc etc.
Your initial conditioning of your battery also has a part to play in its performance as has the age of it. Also data connections also play into this scenario. In addition if you are in a low signal area your phone will spend more energy hunting for e.g. data connections than if you were, say, slap bang next to a transmitter.
People telling you that in 1 hour they saw x% drain or Y% drain tells you nothing unless you know why that is.
Do you want to rethink this and come back with a more focused thread.
Hope this helps.
WB
PS: You can kill off data connectivity by using a utility called Modaco No Data. Might help you if you think your battery problems are bad (do a search).
PPs: There's a stack of threads already on here about battery usage. You might want to link into those rather than kickoff yet another thread on this?

what an angry !
sorry man
Btw its vice versa here. My battery drops about 1% in 3h (or 4% in 12h exactly). If u have bad coverage than its annoying but normal that it drops that fast in standby.
Remember that the battery meter is not designed and is not accurate enouch to measure 1 and 2% of battery use.
If they where, then ALL batteries need to have the exact same discharge cycle. This is not possible.
So 3% one hour, and 1% next hour could just as well be a result from the battery meter calibration.
The battery meter have only two references. Full and empty. All values in between are guestimates

He's right about there being other threads focused on these issues and it's always best to first take a look and see if one exists before starting one. I say this coz I see this is one your first posts and you're probably not familiar with the rules.
As for battery life, yes as WB said there can be too many reasons why your battery drains this much. The most important of which are background data connections, updates, etc. So try using the "No Data" program and see if you get any improvement

all u say, was off (no update, no conection and ...)
when i use the phone battery usage is reasonable and acceptable. but in standby mode, this usage that i have, is much
Wizard,
I guess English is not your first language otherwise you would have recognised I was not putting you down. I was doing my best to be helpful.
I still think your starting point should be to install the application Modaco No Data, run it before you go to bed and see what happens.
There are just so many variable in battery usage, which is what I was trying to tell you.

i do a hard reset, i dont instal any thing, on EDGE, no gprs conection, and ... >> i have 18-19% usage in 6Hr. it's sooooooo much!!
i had same problem with HTC Diamond.
I also, when having no data connections on, regardless of GSM/3G, have a usage of 3% during ~8h (when I sleep).
i install "battery log" and monitor battery usage.
when phone is in use, show 160~200 ma. and when phone is standby, 6~12 ma.
i think its natural and good and acceptable. but why in practice, use so much battery ? ur usage is 3% in 8Hr but my usage is 3% in 1Hr !!!!!!
my phone use battery in other place except windows ?! lol my phone has seepage !
Wizard,
If you are absolutely sure you have all data connections switched off via the Modaco utility AND all Wifi, Bluetooth and Beam connections killed off ( for good measure you could also switch your radio off, ie the telephone, not the FM radio) and you still think battery usage is on the high side then there are a number of things you should consider:
1) You have a battery that was not conditioned properly and therefore is not discharging correctly
2) You have a dodgy battery which you need to change
3) You have a faulty device
4) You have both a faulty device and a dodgy battery.
For no's 3 & 4 I would suggest you send the device back under warranty or ask for an exchange. You know what to do with 1 & 2.

maybe
you have the rare case of phone sleep walking
(sorry for my bad english)
I also have this problem. In plane mode (gsm off), with all data connection off, my battery have a usage of 11% during ~8h (when I sleep).
It's french SFR rom.
Mine's set to UMTS (3g) without having data connections/wifi/bluetooth turned on - it loses 2-3% each 4-5 hours (standby only).

which rom U use ?? (my rom is 1.43) (and i'm waiting for 1.61 official rom ) (without goldcard!)
Hi everyone, first sorry if my english is not perfect, i'm from Chile and this is not my native language. My problem is that I have, SOMETIMES a strange battery drain in my Note 3 N9005 with KitKat 4.4.2 when is in Stand By, i mean without any use.
I will put 2 screenshots which can explain this clearly. In these 2 Screenshots the device was charged at 100%, turned on, disconnected and left on Stand By without any use and all turned off.
When Stand By is ok / normal, I get this, which is really nice:
i.imgur.com/vduTKww.png
but when battery decides to drain (i don't know why) i get this:
i.imgur.com/tKDqqRd.png
Does someone knows what is happening?
Why sometimes I get very low battery consumption in stand by and sometimes not?
The only strange thing that I can see is the Mobile Network Signal, why is in different colors?...signal problem could be the problem? but...why? what can I do? I have my Note 3 for just 3 weeks ago...
I already tried doing a factory reset and wipe cache after the kitkat update...even I have all special function (like motion controls) disabled for better battery life.
I'd really appreciate any help. Thanks.

Hi everyone, first sorry if my english is not perfect, i'm from Chile and this is not my native language. My problem is that I have, SOMETIMES a strange battery drain in my Note 3 N9005 with KitKat 4.4.2 when is in Stand By, i mean without any use.
I will put 2 screenshots which can explain this clearly. In these 2 Screenshots the device was charged at 100%, turned on, disconnected and left on Stand By without any use and all turned off.
When Stand By is ok / normal, I get this, which is really nice:

but when battery decides to drain (i don't know why) i get this:

U have a wakelock mate. Must be apps u installed run in background / keep on wake up to send/rcvd data.
If u r rooted u can flash BBS to find out.
Ps: yes mobile network affect battery a lot. When u r in 4g, it is the most less consumption. 3g not so bad. But 2g it sucks all the way.

Sometimes, fully charged phone may have juice left between 95-100%.
When phone is being charged, the phone stops charging when it reaches 100%. It is to avoid overcharging. Charging is paused until battery level decreases to 95%, then charging starts up again. If you happen to unplug the charger during the pause, you get a phone with not exactly 100% battery, but a few percent less.
It is so on all modern smartphones and completely normal. Even if you see 100% when unplugging, the battery level is reset shortly after.
Mine does this on occassion, out of the blue.
Just starts refusing to go into deep sleep for no apparent reason, without any random apps starting a wakelock.
Only way to solve it is a reboot.

isnt it the other way round? 2g uses least battery, 3g more, and 4g the most?

Correct. 4G uses a high frequency to allow for the massive data capacity. As a result, it's quite weak. 2G runs on a lower frequency as a much more powerful signal and thus the phone has to work less hard to maintain the signal. It does render data usage nearly impossible as a result.
2G is much more battery efficient. Turning your phone to GSM only can save you over two days of battery.
Although if your signal is rubbish (1 bar) it really doesn't matter as it's all going to drain your battery at insane levels.
