Is it just me or XDA II's battery is weak???
The icon on my GPRS monitor show that I only have 4 hours (after full charge) before my battery runs out!! :evil:
Please advise me!!
Don't worry, 4 hours is based on phone talk time

My battery too is eaten up quickly when I activate the phone-abilty. Are there better batteries for sale anywhere?
I am for O2 to release a 'extended' battery.
At the moment I carry round two standard batteries swapping one by mid afternoon, which is a pain.
I would love one high-powered unit

Battery time
I have found in a very non-sciencetific test, that the battery can actually last quite long:
7 hours 30 minutes (night) of Bluetooth OFF and no GPRS connection drained the battery from 100% to 96 %
7 hours 30 minutes of Bluetooth OFF and GPRS enabled, logged on to MS Messenger drained the battery from about 100% to 80 %. I was still logged on in the morning when turning the XDA on, pretty impressive.
Charging in the car cradle (Brodit active cradle) to and from work keeps the battery working all day.
Regards
Michael
I think the main problem is that we want our XDA's to do everything all at once i.e. GPRS online all day, Bluetooth active all day AND we want to actually use it at the same time i.e. make occasional phone calls (up to 1hr a day) AND use the PDA functions (1hr a day) AND perhaps to use it as an MP3 Walkman on the way to work as well (2hrs a day).
Yes it would be nice if it could do this but not everyone wants it to do so much and by providing as standard a battery suitable to last 18 hours (i.e. use all day - charge overnight) would mean the phone is uncompetetive in the market too expensive and too large (heavy). Would everyone pay another £60 ontop of what they paid (I know I would have thought twice)
I also do the battery dance mid afternoon so I for one would love to have a higher power battery (even if it means a bit more weight and size) but others do not. I suppose the real question is when will we at least get the option for a high power battery for us power users?
I think the only batteries available at the moment are the standard 1200mAh does anyone know how much difference would another 600mAh or even 1200mAh make to battery life?
Hi-
I apologize if this has already been asked. I *DID* search around this site, several others and even Google but no one seems to have posted a comparison of extended battery compatibility along with pros/cons of the expanded battery cover backing...
So, like everyone else, my Tilt doesn't last overnight w/o a recharge. In looking at my options for extended batteries, it looks like the largest are the Mugen 3000, the Seidio 3200 and the Mobi 3000.
I'm curious as to peoples opinions on these major points:
1-Duration coupled with whether the battery causes lock-ups/freezes or other errors for the phone...
2-How the revised back cover of the phone compares to the OEM cover with respect to the camera lens, speaker and GPS.
3-Cases and cradle chargers that will work w/ extended battery covers...
4-Tweaks or other hacks needed for the Tilt to recognize the extended battery time.
Thanks everyone in advance!!

Instead of other I think you should have put the option of " I dont know". I think people clicked for the sake of clicking to see the results quicker. My 2 cents.
extended battery
I have a Boxwave 2700 mah and a Seidio 1600 mah battery. The boxwave is from Taiwan with a humped back cover, so I can use my Seido holster, but will not fit in my cradle. Does fit into my Brodit car holder though, and the full backed extended battery cover will as well.
I cannot for the life of me get the correct battery reserve power reading correct. I have tried every tweak and twitch I have read and perused the registry for settings not mentioned elseware, as well as various 3rd party battery utilities, to no avail. Quite frustrating, as I can alarm on low battery, pull it out, put it back in and have 45-60% battery left on the meter. Don't know what else to do, as it does it with my 1600 and 2700 and did it with a "borrowed' Mugen 3000 for a test. Tried all the reccomendations of running it fully down and doing recharge, all that stuff, still wrong indicaitons of remaining power.
This is my greatest frustration right now with the Tilt I have and the other 8 I have bought for employees.
MWS
wow! im having the same problem!
got the mugen 3000 and the reading is always off!
I cant find any solutions!
I ordered the Seidio 3200 battery and tried charging it in my AT&T 8925 Tilt. I left it on charge until the light turn Green.
Starting using it and within 8 hours I was at LOW battery and system died. I removed the battery and put it back in and the battery indicated goes up to 73%.
What is the deal here. Is it my phone that does not understand that it has a larger battery or is it the battery. Since that time I have sent the battery and got a new one and the same thing.
Is there some software utility to tell the Pocket PC that it has a larger battery.
Confused....????...!!!!
Wow, so...
As I sit here perusing options for replacement Wizard and Kaiser batteries (my sister's phone and my own...) I suddenly fear the pointlessness of choosing an extended battery! Has any headway been made on these extended battery glitches in general?
Nope. The Tilt's hardware always expects the standard battery's capacity, and will turn off when that is reached even if the battery is actually twice the capacity and is still half full.
So what you're saying is buying an extended battery is useless because it will shut off at the regular Tilt battery level? Well, glad I read this thread, I won't waste my money.
Yep. However you can remove/reinsert the battery and have more running time again. But then in that case as you have to turn the device off and open the case anyway you're better off getting a 2nd standard battery and swapping it when it's empty. Saves you from having a Kaiser that's twice as thick for nothing.
What About....
Well, I think one objective would be to try charging it as often as possible. It may be that if you plug it back into a charger, it will grant an extension of time. But in the event you are unable to charge it, you could simply remove and reinsert the battery to continue on. Has anyone tried this? I'm curious to know.
"So what you're saying is buying an extended battery is useless because it will shut off at the regular Tilt battery level? "
Could someone please clarify this as I find it confusing as well, I'm just using the times and percent for reference to understand.
Lets say with the stock battery it takes 8 hours to get to 40%.
Will an extended battery like those listed give me longer, like maybe 10-12 hours before it gets to 40%?
I too have searched and read everything from people swearing to get no extra time at all no matter what they do, to people getting double the talk/data time and everything in between, including but not limited to that the usable time gets longer with each recharge. If I'm going to have to take the battery out 3 times a day, I might as well just get 4 or 5 extra stock sized batteries for the same price.
Looking for someone to clear the fog...
Thanks in advance.

Take a read from my post on here http://forum.xda-developers.com/showthread.php?t=336896&page=2
Battery 2700mAh:
"Full discharge removed battery and replaced and gained 10% so not that much of a difference no where near 50%
So effectively i have 2435mAh battery & 10% reserve so still far better than a 1350mAh."
I wish aztilt would have posted which battery he/she has.
aztilt said:
I am one of those that is very happy with the extended battery because the duration from turn on to auto shut off by the phone is at least 3 hours longer than the OEM battery for my usage. I don't have to think about charging the battery or swapping the battery until I get home at night from work. And there is still the option of remove and reinstall the battery if I don't want to charge it right away. I rarely if never need to do the latter.

If I could get 3 more hours before shut-down, that might be worth it. It would mean 90% of the time, I'd get 12 hours of use as long as I didn't need the GPS. It would have meant last week I would have not spent an extra 30 minutes on ice because the GPS quit with less than a mile to go, but I didn't know which way, and I had not way to charge it, so I spent an extra 45 minutes trying to find the highway home when it was time to leave. Just 3 extra hours would have been perfect.
I can't tell you how many times an extra 30 minutes even would have made all the difference in the world, and I really can't think of a time when I needed more than a couple hours.
I realize I'm playing to its weakness. I rarely use the phone itself, but I'm always in email, rss feeds, web browsing, listening to music and using the GPS.
If an extended battery will get me through a normal workday without having to rush home to charge it... That would make me a happy camper.
I have the Mugen 3000
I have the seidio 3200 and after i fully charged it for the first time use, I use it for like 12 hours of txt, calls, internet and normally at the end of the 12 hours i have about 20% of battery left. Just mainly depends on what ROM your using, what radio your using and what programs you have running. Just because 5 people have the same battery doesnt mean all 5 people use their phones for the same thing. Best thing i found is find the one with the highest battery life and go with it.
Just wonder how long can the battery last on airplane. I have lots of ebooks that I would like to read on airplane but wonder if one battery alone is able to last 15 hours.
I've considered buying a airplane charger but worried that not all aircrafts have the charging facility.
Good idea to bring at least one spare battery for the trip?

I suppose it is based somewhat on the battery life one is experiencing, but I am finding I get a full days use with 5-7 hours constant use of internet, MMS and phone. That's a lot of high power use topped off with a couple of hours of playing music and another odd hour or two of ebook, much more than the backlight of an ebook alone.
My experience tells me I would not hestitate a minute to say you'd have ample power for a day of ebook use.

5 to 7 hours of constant use and still lasting a day sounds good. On the airplane, with flight mode on, I expect the drain to be much less severe, so I guess you're right about it only having to produce the backlight.
I guess the answer is there should be no problem then. Cool.

That's even more assuring. Thanks for this info.
sure it's £50, but you might want to look at getting one of these: http://www.expansys.com/d.aspx?i=173540, it's basically a power brick that is supposed to hold 3 charges for your device. The upshot of this is that when your device is running low, you connect to the bank and it starts charging. This means that you have backup power and you don't have to turn off the device, remove the cover, change the battery, replace cover, turn back on!
It's certainly up there on my list of stuff to get once mine arrives!
I have always one of these with me, so I can charge whatever is needed ...
APC Mobile Power Pack
i spoke to htc about the abysmal battery life, they say that there could be extended batteries in the near future, with a new back cover (with the back sticking out)
i dont mind charging it every day but
everytime i do something basic, for couple of minutes, it goes down by 1 percent, everything is turned off, gsm 2g mode, etc.
anyway the guy at htc said its due to the massive screen, this is what drains majority of the juice,
For what this device has and what it can do the battery life is pretty good, if you just use it for a few random pics, bit of browsing, bit of music and a few calls you should get a days use, if you sit there for ages messing with it its gonna drain.
Im pleased with it myself, apart from the bugs, but waiting......
It's killing you literally? Step away man!
I find the battery life on-par with other smart phones I've owned. I use a desktop cradle (well should soon be using a desktop cradle) and an active holder in the car, so I find the battery keeps up OK with a typical day's use for me. The biggest battery killer is when the screen is on full brightness so I find essential to have the phone on power when I'm using the satnav.
I had really high hopes for this thread when I read the title. Needless to say, I'm pretty disappointed.
Where's the death I was promised?
Die and prove it.

To be fair most smartphones drain their batteries pretty damned quickly. Disconnect your data connection when you're not using it and bluetooth too. OK so you won't get weather updates but you'll save battery life. Just charge it nightly and buy a car charger if you really drain that sucker!
Wow, I think battery life is good considering the screen, better than I expected.
Currently, with screen set to 70% brightness, push email on 0800-1800 with hourly retrieval outside those hours, hourly weather/Twitter update, automatic Quick-GPS almanac data update, I last all day (~0700 to 2300), and still with about 20-30% headroom with the following use:
Push email as per above settings
50 minutes GPS tracking
50 minutes bluetooth on (heart rate monitor)
1-2 hours listening to music
Around 1-2 hours high-drain use (screen on, using cellular data/WiFi/GPS - for example browsing/app use/gaming/watching video)
30-40 SMS
15 minutes calls
One simple little trick that I learnt some time ago to preserve battery life is ..........turn down the brightness of the screen display. The brighter it is the more juice gets used.
Get the screen to turn itself off after, say, 30 secs of use. That also helps.
The rest, such as killing off data connections when not in use, etc, you already know.
It never ceases to surprise me at the number of negative comments re battery life. The impression I am left with is that if the battery does not last at least 2 months between charges, even though it is being hammered to within an inch of it's life, then that makes the battery performance rubbish. Anyone ever heard of a battery charger?
It's a really easy to use piece of kit that comes with your device that can be plugged in at night when you are asleep, leaving your device fresh for the morning.
Amazing.

What the heck do you expect from such a phone? The energy management is kinda good and it's the display that kills battery life. You have to get use to it. At least my Touch HD seems to last much longer, but I would never change back.
If you watch a video your battery capacity drops quickly. I estimated 4,3-4,5h of HW-acc WVGA video and 3,5h with a non-HW-acc VGA video. Not that much but it really looks fantastic.
My Solution for this problem is: second battery, extended battery and/or load the battery whereever u can. My normal usage drains 30% of the battery a day, so I get 3 days of normal usage (I'm not an excessive handy user). The standby duration is with 300h not that good, but yeah that means still 12,5 days of standby if I calculated correctly.
The point is, that the phone is that good that I'm attracted to play with it and then the battery life tends to last just a day or less.
I bought a second battery (~22€) just for longer rides. I think it's ok.

EEK!, don't come on this forum and complain about the HD2! not allowed. this is now the official HD2 Appreciation society, don't ya know.
I recommend instead you buy some lube oil, massage it into the device, light some candles, play a bit of Barry White, and all will be well.
Then come on this site and reassure all the sensitive souls here that it is indeed the Holy Grail of mobiles and admit you are a Troll for finding a fault with it, and daring to ask about why it does not preform as it says on the tin.
And final advice...In the words of legendary Basil Fawlty... Don't mention the War !..or in this case, the Keyboard!!, I mentioned it once...and thought I got away with it..but no.

Exactly !!
1000 Mhz this bugger does.
And really its more then just a phone. with the battery cunsumption like wise.
But they told me one thing,,. something that Noone does
When you get the HD2. Its battery got 20% juice init.
Thats not for fun of the company (prolly sanyo) was laizy and dint bother to fill em 100%.
You have to charge the battery 6 to 12 hours and to peeking at your new jewel.
And i know Noone ever does that. But it ensures batterylife and eficiency
Here is the article >>
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity.
Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized.
#DO NOT fully discharge a lithium-ion battery!
Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them.
Instead, charge them when the battery meter shows one bar left.
Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.[1]
2Keep the battery cool.
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
Nickel-based batteries (either NiCd or NiMH) DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,[2] the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd (and other battery chemistries), in many cases misleading consumers into further shortening the lives of the batteries through over-discharging to "recondition" them.[3]
[This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. [4] ]
Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

It's a shame most powerful mobiles heat up like nobody's business whilst on full chat these days.....there's no chance of keeping the batteries cool! Still, it's an expendable item and at least you can buy a replacement.....none of this iPhone 'sealed' tin rubbish.
while i find the battery life reasonable with the features this phone has (read screen size, processor speed), it will be nice to get the CPU throttling app another thread is discussing. don't need that 1000MHz running everytime i pick the phone.
On the same notes, how can i check if automatic screen brightness is kicking in?

are you the first wm phone user? Do you have good experience with phones that has so much specs? Do you use wifi and browse with phone very heavily? If you do, it is really normal that the battery will drain. My Touch HD does the same, it can last a day or 2 or drain like water not more than half a day, it depends on your usage. Try to get a second battery, or even the third one like I do, what is a big deal? It is completely normal.
I don't have a lot complaints on this phone as it meets most of my requirements.about the battery, I seriously don't think it is that bad. for example if you have a car with 1500 horse power and expect it to have or rather 30-40 mpg, don't think it is possible. try to use your local gas station (in this case your friendly charger) more often.move on with your life please.

That might be a little difficult because this battery problem is killing him, LITERALLY
Hi people,
I have recently dumped a Omnia2 for a Desire, just to try Android.
Although it's a beautiful phone, battery life is [email protected], so I'm considering a come back to WM, maybe to HTC HD2.
But before I make my decision, I want to know if the HD2 battery can last for at least 40 hours in my normal usage:
- 40 minutes of phone calls (made/received);
- 90 minutes (1,5 hours) of listening to music over bluetooth, using a bluetooth stereo headset;
- Auto-sync weather every 3 hours;
- Auto-sync email every 3 hours;
- 10-15 minutes of internet browsing;
- Manual sync of my Google account to update agenda and contacts twice a day.
All connections are made using 3G, I'm over a 3G network all day long.
With this daily usage, I got my Omnia2 running for about 65 hours! Let's say, almost 3 days long! I even left it on all night long, without worrying with the battery. Each day consumed 30%-35% of battery juice.
With that usage in my Desire, after one day 45% to 50% of battery juice is gone. I have to turn it off at night so I can use it the next day without recharging. It's about 26-28 hours of total usage before I have to charge it. I don't know if this is normal, maybe I just got spoiled by Omnia2 battery.
What about HD2? Does anyone have a similar usage? Do you think that if I use a HD2 that way, its battery will last longer than Desire battery?
If I had usage like that I wouldn't carry two batteries around with me Music trashes my battery and takes usage above 300mah which in theory is just over 4 hours and I listen quite a fair bit. The desire has a larger battery than the HD2 anyway and I don't think win mo has that great power management.
Hate to be the bearer of bad news, but i seriously doubt that you will be happy with the HD2 battery performance (based on your usage)
im sure you're aware there are many threads re: the poor battery issue, personally i use my phone much more conservatively than you do & struggle to get more than 1 days use (usually 30% charge remaining by the end of the day).
i mostly use edge (switch to 3g if i want to download large email attachments/ web files or watch online vids)
all updates are manual & wifi & bluetooth switched off.
i decided to stop worrying about the battery some time ago & invested in 2 spare batteries. its not ideal but in this case i think the pros of the HD2 out weight the cons.
probably not what you wanted to hear, but this has been my experience, maybe someone can offer more positive feedback.
however if you like winmo, im sure you wont be disappointed with this excellent phone.
all the best.
battery extender
you could try a battery extender like the just mobile gum pro that i recently bought for UK £33 shipped. it's Li-ion with a capacity of 4400mAh, sufficient to fully recharge my hd2 2-3 times from flat without the inconvenience of having to pop the back and soft reset the phone as you would swapping in a spare hd2 battery.
wow, sorry to say this but hd2 is no match for your usage

that is interesting. How long does it take to recharge the phone???
See this thread
Hi,
Take a look at this thread -> http://forum.xda-developers.com/showthread.php?t=718173
I regularly get more than 48 hours out of my battery but then I down listen to music much and definitely not via bluetooth so I have no idea how that would affect battery life.
I dow however use my phone a lot for reading ebooks which mean the screens on for extended periods and I still get to 48 hours +.
I'm busy transferring audio books to my phone so will be able to report back soon about extended periods of audio listening but that will be with the wired headset.
Regards

similar to the mains charger -- a couple of hours, and you can use the phone while it's charging (albeit slowing the charge rate). note: this is using the htc-supplied sync cable to charge which might be limiting the current draw to 500mA. the gum pro is rated for 1000mA output and i've just ordered a mini-to micro- usb adaptor with the data lines shorted which apparently fools the phone into thinking a mains charger is connected so that it may draw more current and charge faster still.
i forgot to mention before that the gum pro is relatively small and light -- think the weight of a pack of cards and about 2/3rds the size.
I do;
30min calls a day
1hr wifi router
30+min video playback
20 reminders a day (sound n vibrate)
All net updates every 30min (twitter, 3 emails, weather)
6am off charger - 6pm back on charger and usually has 40-50% battery life...
I reckon the HD2 would come close to your needs but there would be no margin for error. If it did what you asked the battery would die doing it...
I don't get people who want a phone to last 2-3 days...
I mean, don't people sleep at least a few hours everyday (during which the phone could recharge)?

It's a very good battery life you have there. I guess it would fit my needs.
BTW, you are on Telstra operator, right? If I'm not wrong, Telstra has 3G 850mhz. Wouldn't this better battery life?
