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
:wink:
On the XDA2i, I've been having the small problem of running out of battey since i use it for phone calls.
But, unlike normal mobile phones, the XDA2i doesn't give audio warnings when low on battery, so i find that i end up with a dead phone when i need to make a call.
Is there any settings to enable audio warnings on low battery, or any good utilities which will allow this?
Thanks.
Have you tried Spb Pocket Plus?
It shows a battery meter on screen all the time.
You are also supposed to be able to change the settings in your phone at Alerts to warn you of low battery.
To answer the subject of this post: KBattery is a good, free battery charge monitor, I use it all the time. It sits in the menu bar at the top, where the clock is. Though if you have O2 Active installed, it has a battery monitor on the Today screen. But you've removed that already, haven't you?
As for audible alerts, I don't know how you would configure those. I tend to get a warning (text bubble tooltip style dialog and a two tone noise) from the phone when I reach 20% battery, and a bit later (I'm not sure what percentage of battery left triggers it) I am also warned when the battery is really low, I believe it's around 5%, and it cuts power to the SD card.
I've noticed that various functions shut down when battery runs low, but i dont seem to get any audio alerts. Now and then, the XDA can sit in my pocket for a few days so i might not open it up just to check on the battery level. Therefore, the battery gets drained and i would need to restore a backup.
If anyone knows how to access the setting to turn the audio warning on and off, please can you let me know.
Thanks

Should do the job.
Ever since I had gotten my Nexus One back in July 2011, I had been really pleased by the battery life. With my usage patterns, I could easily get two days on a charge, sometimes getting three comfortably. All of the sudden, about half a week ago, I noticed that the battery would discharge itself really quickly. It would go from 100% to around 30% in a day. I hadn't changed my usage patterns, nor had I installed any new apps. I went into the settings for any apps that may be loading data in the background (Twitter, Facebook, News/Weather, etc) and made sure background data was enabled, and I always turn off mobile networks (EDGE/3G) and WiFi when I'm not using them. I even went as far as wiping the phone and resetting everything, but no change in battery life. Calibrating the battery by letting it fully discharge and then charging it fully while the phone is powered off also did nothing. I'm at a total loss here. This seems inexplicable as to why the battery life is now so bad.
i change my battery every 6-8 months batteries are stupid like that i had this problem also like 5 months ago i just bought a new battery then BINGO 3-4 days on 1 full charge with every know battery tweaks if you look for battery look in the Nexus Q&A thread someone asked whats the best battery life ... hope i helped
here's the post http://forum.xda-developers.com/showthread.php?t=1569069
Thanks. I think I'll order a new battery, probably a standard 1400mAh battery instead of one of the larger-capacity extended batteries. I don't really want to add any more weight or thickness to my phone. If that doesn't seem to do the trick, I'll probably just eventually buy a new phone. I've been looking for something different for a while now and this will give me a good excuse to do so. Heh.
I don't want to jinx myself here, but I may have found a temporary solution. Use only 2G networks. Curiously, about two or three weeks ago, I noticed that the mobile network type has changed from HSPA to HSDPA. AT&T appears to have done some upgrades to bring "4G" to the area. I wonder if the changeover has done something to my Nexus One and now was drawing more power from the device searching for a signal? Ever since I've disabled 3G, I've been on EDGE and I've only lost ~5% battery compared to the near 25% that I had lost on HSDPA. I'll check back if I find out anymore information.
One option is to try to recalibrate the battery. There is a root app out there that allows / guides you how to do this. Just search battery calibration. Additionally, instead of using an app, what you can do is boot into a custom recovery image (preferably 4EXT touch) and wipe the 'battery stats'. Then turn the device off, charge til the LED is green and then leave on the charge for an hour after it turns green (maybe overnight?). Then run the battery full out the next day to properly calibrate it.
Yes, 2G mode only does save a lot of battery. Apps that sync in the background (IE Gmail, FB, Twitter) use battery a lot. From your post it sounded like you have them set to auto update. Disable that or force it to refresh less often. What is sounds like is that your device maybe trying to connect to cell towers but is having a harder time; this may be due to ATT's 'upgrade'. I'm not too sure about that stuff though, haha.
Just as I had expected, I believe that it is an AT&T-related issue. A friend of mine who has an Aria has been experiencing the exact same battery drain issue that I had been having.
recalibrate your battery
1.drain your battery until you get the message "powering off"
2.quickly connect your charger
3.charge it 8 hours straight..
Battery calliberated...well it worked for me...:thumbup:

I had the exact same problem. I had a refurbished nexus one, everything was working fine for a month then suddenly one day battery life goes from 14-16 hours to 4-6. I call customer service and search online, do all the battery pull out replace and whatever but no result. Took it to a shop, they couldn't figure out how to fix it but mentioned perhaps I should change the power strip (the black plastic card wich has the power button, camera and flash attached to it). Look at ifixit nexus one teardown for the actual part. So I bought a new power strip, replaced it and my nexus one is back to its original 12-14 hours. Not sure if this will help you, but that's what I did to fix mine.
Hi Everyone
I’ve bought yesterday a brand new Samsung Galaxy S4 here in Brazil (model GT-I9515L, it’s a Snapdragon 600 4G one), and I’m kinda worried about my battery life, which drags 1% every one or two minutes on simple Wi-Fi web browsing, I have been from 100% to zero in less than two hours, and I honestly don’t think that is normal.
I’ve tried a lot of things, I tried disabling some battery dragging features like the gestures, gps and etc, and still got terrible battery life
I’ve noticed that if I sit the phone down idle (screen off but powered on), it doesn’t seem to drag the battery much, when idle it seems equal to my Nexus 4 that I had previously, I'm starting to miss this phone more and more since I got the Galaxy.
The charging time is normal too, it goes from 0 to full in average time, two hours or so.
My phone is in 4.4.2 Kitkat (TouchWiz, unrooted) I’ve haven’t done anything to the phone other than apply OTA updates once it turned on the first time.
I’ve tried doing a factory reset via the settings menu (is this the same thing than reseting from recovery?) and not installing anything after but still got the battery drain problem.
Thinking that it was a faulty battery or phone I’ve brought it back to the store (an official Samsung Store here in Brazil), but they told me that my software was out-of-date, which I thought was strange because both the Software Update menu in phone settings and Kies found no updates to be applied.
I watched them as they put my phone in Odin mode and plugged my phone into one of the store’s computers, opened a program called “samsung master” in order to update my phone, but they couldn’t do it because my “Knox” was somehow messed up (which isn’t because it shows as 0x0) and told me to come back another day when the technician is there.
I became really frustrated with this, so far what I could diagnose was that somehow that my battery drain problem is a software one, and is solved by some kind of update that isn’t available by Kies, just in Samsung stores.
Can you guys give me any directions? I’m open to suggestions and if you guys need any other information, please tell me that I can post here, sorry for my English because I’m brazilian.
Drain almost always applies to when your screen is off. If you don't have drain while your screen is off, then it's perfectly normal.
2 hours of screen on time is perfectly normal. Your screen uses power, not much you can do about that.

When it's off, the batteery seems to last, but the performance is way worse than on my Nexus 4 (which is known for it's bad battery performance) when it comes to screen time, I've got near the double web browsing time on the nexus.
Your galaxy drains battery like this too? it seems insane to me. 2hours from 100% to zero without any of the features, brightness on the lowest level, only Wi-Fi on, I don't think every galaxy is like this.
When I brought them to the store, the salesperson told me that it had an update to be applied, but when I search for an update or put it into kies it shows me as up-to-date, do you guys know anything about that?
Here you can find the latest

Though I doubt a firmware upgrade would change it.
And yes, 2 to 2 1/2 hours screen on time is what I get.
Any ideas if this is even possible? I know the LG G4 has this and it's something iOS has ... would be very useful ..
This annoyed me as well because I came from a LG G3 and it did it out of the box. There are apps in the Play store that claim to be able to show the battery level but most are tracking usage and estimating, not actually receiving the battery info from the device. I know the devices I have report the battery level because it worked fine on my G3. Its really annoying to get into the gym with your Bluetooth headphones only to have them die a couple of minutes into your workout because there is no way to know the battery level.

Aye, that's the exact same problem I have. It's pretty irritating ...
Same problem coming from a LG G3
Still no solution ?
I can see the battery level on my Samsung Fit Watch 2 on my phone, but there is direct software support for that one. I wonder if other Samsung BT gear has the same feature.
I use Samsung Level U bluetooth headset, and the app show the battery level...
