Battery life fix??

Hi everyone,
I don't really post much on here, but I've been lurking around for ages & finding this place very useful for modding my MDA Compact II. Thanks for that!
I've been looking for a while for some sort of battery fix?
I've had the same battery for about a year now & decided that it was time for a new one. So I got myself one ordered from T-Mobile in the US & had it shipped over (not cheap!).
I put it in my phone & charged it for 48 hours then started to use it, unfortunately it only lasted about 6 hours!? So I contacted T-Mobile & they sent me a new one.... Same problem!?
So I'm beginning to think its the SW?
I'm running the new HTC Touchflow OS with a few other bells & whistles!
Can anybody suggest a fix please! I don't want to have to buy a new one!
Thanks.

Who told you to charge it for 48 hours? That doesnt even make sense with this kind of battery. Try to discharge it and charge it to 100% again.

Yeah strange hey?
Yeah I've tried that a few times but still the same rubbish battery life??
The battery is a PM16A if that helps??

I read somewhere a while back (Probably here), that your battery life could be affected when you update the ROM? IE: If it is not fully charged when you update.
Is this the case, is there a WM6 fix for this??
Thanks....

Its doubtful to be a software problem. You can of course try flashing to WM5, then again to WM6, see if it helps.

HD2 battery test...

I am having problems with my battery life on HD2.
Currently I use ROM Duttys Leo V2.2 with radio 2.06.51.07, but I tried atleast 10-15 different ROMs and radios (Miri/Laurentius26/Xanny/Sternas ROMs and others with all bases from 1.66 up to 2.10).
I made several tests with tbattery and logged the results, this is what i get (Current values):
- screen off -> -13
- screen on 10% -> -83
- screen on 30% -> -102
- screen on 100% -> -214
The tests were made on 2G connection with max signal, with no data connection.
My battery usually barely lasts 2 days with very light usage, with moderate usage i have to charge the phone every day. Maybe this is normal, I just hope it's not...
Can someone throw up some comparison numbers please? I already wanted to bring the phone back and demand a new one but I am not sure if something is actually wrong with it.
BTW, I use MTTY for flashing and always do a hard reset after the first full boot. Tests were done with a clean ROM install, with no aditional processes running.

verry much like this
anyway its normal im affraid of with moderate use and the end of the day i have about 40% left.

Yes, perfectly normal battery life, sorry to disappoint but that's how it goes with smartphones

It is running a computer spec, that, not even 8 years ago, had to rely on mains power. Not to mention the internet router, the screen, the GPS device, and not least the phone which are all inbuilt. I think running it for a day on a battery is pretty impressive personally.

Thanks for the info guys, I feel much better after reading that battery post from kilrah...
I was sure there is something wrong with my device, but when I look at it from rp-x1's point of view, I guess it's not that bad...

Sorry to put a downer on you, but its the way I look at it. I know it isn't the biggest capacity battery, which does have a bad effect on battery life, but unfortunately it is a computer with a phone, rather than the other way round.
My previous phones:
Nokia 3310 (basic phone) - a week
Nokia 7610 (one of the first proper mainstream "smartphones" by Nokia) - 3 days
Nokia E90 Communicator (their flagship smartphone) - 2 days - at a push
Sony Ericsson Xperia X1 - 1.5 - 2 days - at a push
Blackberry Bold 9000 - a few days, if I don't actually use it.
HTC HD2 - 1 - 2 days (dependant on usage)
It seems to be the norm for a smartphone/pocketpc to be around a day to a couple of days on a charge.
To add a bit of perspective, my colleague has an iPhone, and it lasted a whole 3 hours on a single charge when using Exchange Push-Mail. It usually only lasts a day too.

At least on the HD2 you can change battery and go on

Yes you have a point there, when I had my iPhone and used it as much as i use HD2 last few weeks the battery was about the same...

so true i bought a battery from ebay ( was only €4 and its almost as good as the original one, it only fits a bit too tight..) i always have a spare fully charged one in my wallet

Battery again...

I'm on Twilight DFC ( last version with htc hub )
Rom use : 2.14.50
HSPL : 2.08
card SD : micro SD sandisk 4Go class 4
Magldr : 1.3
Use : no really ( check my mails every 3 hours , 20 sms per day , little internet with 3g.
Désactivated : my 3g, wifi, localisation for a better battery level. My emails are checking just every hour by option.
Results : 100% at 8 A.m , 20% at 7 P.m ...
The battery are very drain...
with rom 2.15.50 it is the same
rom i have use : xmob 1.3 / 1.4 , moonlight ... and.. it is the same problem.
Please help me .

Same issue here. It's about 60mA battery drain, guess something wrong in power management.

You've most likely forgot to disable bluetooth completley. There is a 60mA BT bug in some roms.

bluetooth is off, but the battery running time is still bad. What Radio Rom is definitely the best ?

How to completely turn off bluetooth? It was turned off in settings

Yes, Settings/Bluetooth disable

2.12.50 with the battery tweak found in the development subforum gives me over a day with moderate to heavy usage (games, 3G internet, 3 e-mail [email protected] min, 30 min. voice calls). In standby (only mail sync on) I get 10-12% battery drop over the night.
Wait for a few recharge cycles and it will settle. At first I got 12-15 hrs. After 2 weeks it got MUCH better.

is your batter being charged propperly?
The battery tweak sets the full level for the battery.
you must first charge the battery to its maximum level then run the reg tweak
Now here is the problem, WP7 on our HD2 will not charge the full batter all of the time. Quite often you must charge until it goes green, then reboot and charge so more, keep repeating until the HTC battery tool reports the ACR level roughly the same as the FULL level.
to give you an idea
Ive just charged my phone over night, it says its full, it wont charge any more but the tool reports it only half full, even though the indicator shows full. But my battery life will drop like a rock and may report being empty when its not.
If i restart my phone just now the tool shows a jump in ACR value to about 800mAh it then allows me to charge the remaining 400mAh.
or you might find that restarting it shows the battery is full in both indicator and ACR value
The point is, after a full charge, restart the phone because until you do the phone doesnt appear to know whats goig on wth the battery, im guessing this is something to do with the fact that the HD7 and HD2 DO have some small differences inside.

I think what frustrates me more than anything else is the sheer unpredictability of my battery performance. I have done all the tweaks and installed the battery tool but overnight in the past week I have seen the battery go down as low as about 15-20% and remain as high as 80% with a range in between (estimated values, of course).
I'm now going to try to look at my data usage to see if anything is causing the radio to work extra hard some nights and not on others.
If it was at least consistent I could then start thinking about Radio versions, management strategies and the like but while it's so variable it a bit hard to get scientific with it...!

indeed it is a bit of a pain but remember we were never ment to have this ROM.
remember though it might be unpredictable because its not full, its not as easy as it sems to get a full charge, even when htc battery tool and MS tells us its full it might not be, persistant restart and charge usually gets it done

It is definitely battery problem exists! Don't try to hide it because all that stuff you are talking here to solve that is not working! Test in 2G network without any BT and WiFi during 24h failed, battery completely drained without reason.

no one is saying there isnt a problem, there are seveal problems
The big one is you shouldnt have WP7 on your HD2, our device was not supported, you cant say the HTC HD7 is the same because it is not, largely it is yes, but internally it has differences, one of these differences seem to be the controler for the battery
To be clear, WP7 cant report the correct battery level without tweaking it, and in some instances WP7 will not completely charge your phone but it may appear full there by leading to quick battery drainage

I second that. I think it's the matter of hit and miss. I have two hd2s, and one of them has ****e battery life. Both are using the same rom, same radio, same battery optimisation technique btw.

I bought an HD7 cause of the battery drainage of WP7 HD2, multi touching, downloading from market e.t.c!
I know HD2 is better than HD7 because you can have everything but... WP7 is my thing ya know??? So if you guys liked WP7 just go out there and buy your selves an official WP7 device! Believe me i l.o.v.e it and i will stick with it!
Battery life on HD7 is stunning! I have it running 3 days now and now i have 20% with moderate use..

Worse recommendation I ever saw. When first android port was released, there was huge battery drainage too but now I'm using android on my HD2 with 3 days batt life and I didn't buy new android device. So it can be fixed without wasting money.

In my opinion..Android is boring.. I know that battery life on Android HD2 is awesome but the OS is very Boring... When i flashed WP7 i said "this will be my daily OS" (i love simplicity..)... At that time i needed to charge my battery daily and i was a little bored of the hard keys and battery and stuff like that! (also i had some lost pixels on the screen) Didn't wanted to go back to Android though! So why do i have to keep my boring HD2??? Since i wanted to run WP7 as a daily OS i got my new HD7 (for 150Euro)
I am Just telling my opinion and i hope you agree with me...
I am a tech lover guy...Yesterday was iPhone, after that HD2,today HD7 and God knows what else for tomorrow!

where to get an hd7 for 150,- euro????? i'll going out and get two of them, too

for me wp7 is boring until now. almost no customization.. when you want to turn off data or wifi or bt you have to navigate through 2 or 3 menus.
and it is slow even though there are beautiful animations. (contacts open in about 2 seconds and in android it is about 0,5 seconds)
i am all for simplicity as long as you have all functions and speed.
btw battery is enough for 1 day with moderate use but forget using it from early morning and a long partynight
(camera issue still a bummer)

im all up for opinions on here....so ill give me own
Im sorry but i have not seen a more fluid and resposive device then the HD2 with WP7, iphone, android on various models even WP7 on other devices dont appear as quick as mine but thats the luck of the draw with using our HD2 some folk have had issues others think its amazing. contacts for me, around 200ish load instantly
luck of the draw
battery life is a concern still as is the camera other than that all is good

I'm not agree. You didn't notice that "super simple" WM7 consuming more energy than "boring" android? And what a point of this?
You know what, rich people always bored. I got my first iphone (3gs) just 3 month ago, and HD2 was like a gift from my friends in America.

[Q] Whats up with the battery life?

I've had my hd2 since it came out, and am a regular tester of various roms and windows roms. When i got WP7 nodo a few months back i noticed that my battery life was, well, terrible. After trying every battery trick, charging method, and the like, the best i could get out of my battery tool is 120ma, which is like 8 hours of charge for me (TMOUS, 3G on, ~30 minutes of gaming, ~30 minutes browsing, ~25 texts per day, ~30 minutes talking, wifi and background stuff off, brightness moderate).
I've switched back to android since, but i was wondering if those problems persist in Mango? I noticed the big dog, Cotulla, released a ROM and if anyone could tell me if the battery problem is fixed? If not, Whats causing the battery problems, besides the camera (idk if that was fixed, but it was a big problem in NoDo)?
Becuase i really want to switch back to Wp7, but that battery life man.....just can't live with it.
Anyways thanks y'all!

Exactly!
I've been using XBmod & Yuki's Back to the future WP7 8107 ROM, and while I LOVE the ROM, and having WP7 on my HD2, my battery life is TERRIBLE! I too have done all the posted "tricks", but I'm still charging my phone all day. If I can't find a way to increase my battery life, it'll be back to Windows Mobile 6.5.x for me.

I have approx. 2 hours of calls each day and with WM7 I must charging my telefon min. 2 times in one day. So its very horrible. Would be nice to find any fix for it

Batteryyyy!!!!
Hi people.
Unfortunately I'm not reply to give you some fix...I have the same problem and I' still waiting for a fix, maybe if we are more the fix come more fast lool

Battery problems on HD2 solved

Hy everyone. I had urge to write this small post to save time searching for solutions.
I bought HD2 from US via ebay. Yep it had some problem but fixed them all except battery drain.
Normal battery would not last more than 6 hours and extended one more than 12. CRAZY!
After a long time I decided to find the cause. Checked with apps that most of battery drain goes to Android OS. It was strange as I thought it will be the screen.
Than I decided to change OS so went from 2.2 to 4.0.4 Also HARSPL from 2.10 back to 2.08.
Works like a charm and the best thing normal battery lasts one day with intensive usage.
