Hi everyone,
I have having a terrible battery performance for my mini. It seems that just after 2 hours, the battery level drops from 100% to about 80% :shock: . Any idea why? :?
Does anyone else have this problem?
Thanks!
Try to look in Start/Settings/System/Memory ---running programs...you may have some programs running and consuming battery. If U have Pocket hack master it drawn the battery very fast if overclocked and installed!

Hi Primoz
Thanks for the info. But on my previous device XDA IIs, even with the applications running, the battery life was still ok.
Sigh... perhaps my batt is a lemon... so far it has only lasted 1 day with a full charge!!! :shock:
Hmmm...strange, if the I-mate is new try to replace the battery...cause for me the battery life is about 2 days...in average. If not used much 3-4 days.

Hmm, perhaps an investigation is in order :?: :
Did you leave your beam receive on?
Are you using bluetooth?
What programs are running, especially today screen plugins?
Hi,
nope, bluetooth is off, IR is off however, I left the SD Card in the slot all the time.
I have also made sure there are no today screen plugins and also programs running in the background.
I just checked.... 1 hour, the battery level drops by 6 % :shock:
This is terrible. I am using XDA II mini... don't seem to see this problem with i-Mates and others though...
anyone with XDA II mini care to comment?
Perhaps it's because your battery is still new. On average, batteries have full capacity and stamina after 10-20 cycles of full charge-full discharge.
Make sure:
Backlight is on low setting.
Bluetooth is off.
Infrared is off.
Power off after x minutes.
Backlight off after x minutes.
I have only had my XDA Mini for 8 days now and my battery life is much better than that.
The phone and PIM gets a good going over during a business day and then a couple hours of WiFi in the evening when i get home and i have never had the battery drop below 30%.
My XDA II used to be flat by the end of the day.
The difference is now that i charge the unit for 7 hours during the evenings as opposed to the XDA II sitting in the craddle during the day.
I have finally given up on charging and recharging the battery. I just sent my mini for servicing yesterday. Apparently, the service folks also think that the poor performance of the batt is due to a faulty power regulator.
Anyways, I was quite disappointed that I got a lemon. They promised me my device back by Friday or Sat.
Will update again on the batt performance once I get it back.... :?
Hello!
I have the same problem and if you know where the problem came from i would be very interesting , to know if i have to send it to repair too or if there is another solution!
Thanks
how do you turn IR off?
To turn of IR....
Start>Settings>Connections>Beam
Uncheck the box which says receive all incoming beams.

Hmm...strange, because I have read somewhere (don`t remember where) thah if the Receiving beam box is checked it "helps" the battery to last longer... :?

I just got back my set from the O2 repair center in Singapore. The service tech said that there wasn't any problem and the battery drain is at an ACCEPTABLE rate!
I am still getting the poor battery performance. I can only last 10 hrs max without USING my PDA. I did not even use the PDA function extensively ( at most 20 mins) and did not even use the phone.... yes, all the applications were stopped and even disabled the IR.
I escalated this issue to O2 and they told me that they will check with the tech about the set....
This is terrible!!!! :x .....
Anyone else with this problem? I suspect that this is an hardware / battery issue.
Sigh... hope that O2 can do something about!
to mod: sorry about making noise about this.... but I had to let it out of my chest!
Anyone else with this issue....???

Maybe try the backup and hardreset route? Must be something in your settings that's draining the battery.
If I can tell my experience...I never mind if battery is full of charge or it is down...'couse whenever I can, I always connect my S100 to USB for recharging...
Uhm...Do I wrong?
I guess for my type of usage, it is unacceptable to always plug it into the charger.
This is because I am on the move most of the time and once I leave my office in the morning, I would not return home till sometime at night. Need the set to last at least 24 hours!
Sigh... anyone has ideas for a workaround?
I've been looking for an additional battery... where to get one?
Is this particular to O2 sets? Cos I have not been seeing compliants with other vendors iMate, T-Mobile etc..
I have the same problem and have try all software solution(differents roms)!!I will send it to repair and hope i will be more lucky than you.
Wish you all the best too! If you do get it fixed, please let me know so that I can do something about it rather than having to deal with O2!
I am getting quite impatient with them for giving me the runaround!
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

backlight - min??
turn off the backlight after 30sec??
button lock except power button??
I have an XDA Exec and I have just upgraded my ROM to the newest QTEK version. Since then, I have noticed that it crashes and reboots when the power level showing on the power meter reaches about 25%. I don't believe this problem was occurring before the ROM upgrade.
Although it stops working when 25% power is showing, I do not think that the battery life is actually reduced at all. It seems to me that it is more like the guage is inaccurate now and the power is really near zero when it crashes.
I wondered if the power guage needs recalibrating in some manner after the ROM upgrade because the settings have been lost. I know that some laptop computers need their batteries to be calibrated on first use. Does anyone have any ideas or information on this?
Thanks
Mark
Mark,
did you ever solve this issue? I have the same problem. Thanks for anyone's help.
Have only just noticed but im having the same problem to so annoying
Bad news, I am afraid. It is a harware fault and needs a repair.
In the end I returned my Exec to O2 under warranty. I got it back last week but they had forgotten to return the battery. After a phone call they sent me a free brand new battery by next day delivery.
Unfortunatelyt this means that I can't say for sure whether it was a battery problem or the phone itself. The covering letter with the phone said they had found a fault and repaired the phone, but since it seemed to be a stock letter, I can't be sure.
Anyway, my Exec certainly works fine now. I can get down to less than 10% with no crashes. I definitely did not have anything to do with the ROM upgrade.

Mark,
Thanks for the reply. That was not what I wanted to hear! I am going to continue playing around with it; I can't believe we're the only ones to have this problem. Let me know if you get any more news. I'm getting tired of sending the HTC in for repairs.
i-mate crashes with battery in less then 43%
My i-mate continues to crashes with the battery is less then 43%, apparently the problem occurred when I make the upgrade to ROM Qtek WWE_13077_130176_10900, was looked like that this version has something that change the battery configuration, since Qtek 9000 comes with 1750 battery mAh? I reinstalled the i-mate ROM 1.30.82 and the problem persists?
I made a test leaving the i-mate on, without using the radio until the battery settings showed 23%, then I made a phone call, the i-mate crashes in seconds. Somebody could inform what is the true voltage of the battery in the i-mate when it is 100% and when it is 10%, at the Main Battery settings?
Battery problem...u ccan verify this by using a differrent one may b from yr friend...
I have the same problem, its only started happening after the ROM upgrade from o2, before it would run down to 0% no problem but now it gets to 25% crashes and i have to reboot it and turn the backlight of otherwise it crashes again. Are you sure its a battery problem because ive had the same battery for 6 months and the problem only started after the upgrade.
Thanks to all of you guys for adding comments. Good to see others with the same problem. Misery loves company.
Anyhow, I can't exactly say my problems started with a ROM upgrade. I have two used universals. Here's my story:
PDA#1. Upgraded with previous Orange ROM as soon as I bought it and started having the 25% crashing problem
PDA#2. Never had crashing problem, upgraded latest Orange ROM, down to nearly dead battery today and no crash.
Hmm, to test the bad battery theory, I will swap the battery in PDA#1 with the battery in PDA #2, and if I get a crash, I can blame it on the battery. Otherwise, it's the OS. Both PDAs have EXACTLY the same programs installed from fresh ROM upgrades.
Battery test
Hi PDAholic.
Which was the result of the test with the battery.
Hi
See my previous post in this topic. I can confirm that my problem seemed to start when I upgraded to the newest QTek ROM (from original O2 ROM). However after it has been returned to O2 for a repair, I have once again upgraded to the same ROM and now it works fine.
So, it must ether be a hardware fault on the Exec or a battery fault. My evidence is not consistent with it being something to do with the ROM version.
Anyone have definitive information on this problem?
Mark
Mark: I thank you for your post--but you have to admit, there is nothing wrong with a little experimentation!
Josedias: My experiment is still underway. I will say that taking out the nearly dead battery from non-crashing pda and putting it into the crashing pda did not result in the latter pda crashing. However, I am now waiting for the battery from crashing pda (which is now in non-crashing pda) to die. If it does, the problem is the battery. I actually have another theory if none of this pans out, which I will present with my next post.
Pdahollic
Will be good to hear what your fndings are.
I spoke to o2 today and told them about the problem with the battery they tried telling me that it was software related then i told him that i was using the latest software from there website and he was like hmmm ok let me put you through to returns. Got put through and the kind person that i spoke to there said just to pop it in the post with the returns number and will send you out a new one the same day.
So i should hopefully have a new 1 by the end of the week will let you know if i have any problems
Okay, interesting results here...
I was actually unable to reproduce the shutdown on either PDA, with either battery!
I have a theory why, and perhaps those of you with the problem could try and see if it fixes your devices.
When I started the experiment, I wanted both PDAs to be as equal (controlled variables!) as possible. So, I charged both overnight until the green light came on, then did a soft reset to both PDAs. I have a feeling this might have somehow reset the battery meters in both devices.
Pretty much all PDA manufacturers recommend when you first get a device to charge it to 100% then begin using it. I do know that when I did the ROM upgrade on the device that kept crashing, my battery was very low. So, I presume that when I started using the device, the battery calibration was way off. Say that the device thought the battery was at 100%, but it was actually only at 75%. When the battery discharged to 0%, the device thought it was at 25%, and thus did not issue any warning messages. Then, without warning, the device died and would not come on without charging (which is what mine did).
I don't know for sure if this is what has been happening, but it makes sense to me.
My next experiment would be to stick a near dead battery in a device with a fully charged battery and see what happens. Although, at this point I probably "ought to leave well enough alone."
Again, I suggest to all of you to charge the device overnight to 100% WITH THE GREEN LIGHT ON, then do a soft reset and see if your problem is solved.
I will keep you guys posted on any further problems. Good luck.
Hi everyone!
A bit out of topic but I could not find any other discusion that could relate to my problem which is also related to battery.
I've got this guy who bought a brand spankin new XDA EXEC straight from Taiwan and the lame ass used it for about 4 hours without preformating the battery until it seized on him. It happend at the time of Active Sync instalation.
It did not die out sooner because he had it connected all the time to PC via USB cable thinking that this will charge the battery.
Now all he can see is the O2 welcoming screen and the ROM initialization figures.
Any ideas guys? I feel sorry for him and am trying to help him somehow.
I presume he has tried to do a hard reset (both softkeys, reset button and power). If that doesn't work, he could put it in bootloader mode, disable USB, and try reloading the ROM. Make sure he realizes that it takes a LONG time to soft reset the Universals. A common nube mistake is to keep hitting the reset button thinking it has locked up on the splash screen. Not that I would ever have done that...
I received a T-Mobile MDA Pro on tuesday and it has the same problem - but, my battery seems to die at 50% and will only power back on when the charger is plugged (mains or usb) in?
Hi guys ive just been on the phone with o2 and i have been told that it is indeed a hardware fault and that i will be getting a new one back from them in the next few days.
Qtek 13077 ROM ????
Could somebody inform what is the true voltage of the battery in the i-mate at 100% and when it is 10%, in the miter?
I have charged the unit till 100% led = Green, then soft reset, the problem persist?
Now I am 100% certainty that the problem occurred when I made upgrade to Qteck, we needs to investigate what the the Qtek ROM this doing with the JasJar?
Weird thing: Every now and then my Atom Life reboots when I get an incoming call. It rings for around 2 seconds and reboots. Any idea what that may be? I have no other problems at all, it never restarts when anything else happens!
Crikey!
that happens to me as well. ****s me to know end... I think the battery charge may have something to do with it. ie if my atom life is fully charge i don't think it happens? it just seems to be when it gets lower... great to know i'm not the only one with this problem though.
the same problem.it happens all the time when the battery is at 40% or less.
I think you're right. I changed to another battery I have, and that seems to have fixed it. Strange thing is that the battery I have used so far has been between 70 & 80 % when it's happened, and it dies at around 40 %. Probably a faulty battery. Thanks!
you mean your phone works fine now,even on 20%?
Actually, i've read on several forum that Atom, watever model it is comes with a battery that is somewhat faulty. Changing to another battery other that the default one actually solves the problem of it shutting down @ 40%..
Bikiapo, unfortunately, no. I thought I had fixed it, but I hadn't.
Lann_78, that doesn't surprise me! These units have a few problems that are really annoying, but for me the postivies (fast CPU, good connectivity, small size) makes up for it in my book. I have a few no original batteries laying around from my previous Atom, so I'll try with those. Thanks!
im wondering what O2 says about all of this.because im sure they know.we bought our devices with money not with nuts.all over the internet they talk about this devices with the worst words.O2 MUST DO SOMETHING!!!
Well, since I changed the battery I haven't had any problems. I guess it's a subcontractor that cut corners on the battery. I guessing that they simply can't keep the voltage at the necessary 3.7 Volts when they fall below 50 %, or whatever the real percentage it is, and there's a surge in power usage, like a call coming in.
i just buy a battery 3550 mAh.till now was 1530 mAh.do you think it will fix the problem?
Probably. Those batteries are very thick, so you need another backplate. But you probably got that as well in the package, right?
yes there is one in the package.have you ever saw a battery like this one? is it much bigger than the original battery?and the weight...?
I have no idea, I have only seen it in the eBay auctions, and I know that if a battery has that much more capacity and has a new backplate, it must be bigger. Which is why I don't buy one, I like my aluminum case too much.
same problem
Hey i was under the impression that aftr i dropped my O2 Atom life a couple opf times the batery has started behaving erratically.....good to know that others are also facing the same issue...in my case the phone goes off and then i need to put it on...is it the same what everyone else goes trhough...i too feel that only when it is below 40% mark this problem happens that an incoming call rings for a few seconds and then the phone goes off...
visit the site gsmerana.com and you will see thar we are not alone.many owners of atom life with the same problems.
I've got the same problem. But it solved now.
Just change the CPU profile to best Power. It works on Me
Strange. I always had the CPU profile set like that. It didn't do any good for me. But what did help was to use another battery. I haven't had the problem since I stopped using the batteries that came with the thing.

It's true the battery that came with the package didn't fit excatly in the device, the battery size a bit smaller than the slot. So i try to put some paper so the battery could fit in.
The fit isn't the problem. The problem is that if it's below 50 % charge the voltage sinks so low that a call will make the phone restart. And even turning on the WiFi can reboot it.
hey there. new in the forum, new atom life for me..
but i had the same problem as you guys.
the thing is that atom not only restarted, the device couldnt boot at all. after several tries i had to do hard reset... twice in 3 days.. and thank god i didnt have any important data to lose at the moment, but who knows in the future?At the beggining i thought that some programm crashed but now i see there is something more serious here...
All we have to do is send our complaints to O2 about all this. if this is a manufacter problem then they have to solve it for us... dont you think?
hello guys,i recently bought a used o2 exec with 2 batteries(one extra old used battery) and pretty much disappointed with it,coz its almost like a dead one,its always turning off even when its fully charged,it stays for max 4-5 mins of work and tends to turnoff suddenly(the image is fading slowly and blackens up ending).then only remedy is to plugin charger in order to start it again.i had tried both batteries,but same problem occurs again.....now in the forum there are various methods for recaliberating battery.
1st) method says recalibration using bootloader mode drain method-it doesnt works as even in bootloader mode my exec turns off automatically even if battery % is much higher(60%,50% etc).
2nd)recalibration using plastic tape covering on one of the battery points in order to drain battery==same automatically turns off even when 70-80% battery left
now what i just want from you guys is a simple answer to my question-should i consider my exec as a brick & stop using it
or
take 1 more chance & buy a new battery.& try it on my device,i think this may not be a battery problem as battery calibration is also not workin,may be its a device hardware problem......
a batt can be defect and not being seen as such by % or fixed by calib
one of the biggests issues with laptops, phones and..... today imho is
that batts are crap
the % is never correct the usage is never linaer
and a defect batt can be seen as working ,,,,,
buy a real battery, they are more then the ebay ones but are worth every penny i have a bad batt right now as well i cant get more then 8ish hours sometimes less, but i bought from one of the better batt companies which was more money but lasted 2+ days and i will do so for my UNI i love this device
