I think the real confusion is what many defined as full discharge vs deep discharge.

Quote form http://www.batteryuniversity.com/parttwo-34.htm

"Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this."

Not claiming I have authority in this matter, I regard the "cut-off point in the equipment" as deep discharge. In this state, the device will power-up then promptly shuts itself off to protect the battery/data/etc.

I think this should be relatively safe for the battery as we(I) frequently run Li-Ion batteries flat in mp3 players, PMP, GPS, laptops, phones, gaming devices, etc without much consequences.

As long as you recharge it before the voltage in the battery drops dangerously low (<2.5 volts), it should be fine.

Compared to deep discharge (holding a couple percent of charges), I regard full discharge as when the device does not respond (power up) at all. Then again, if you recharge it within the day or two, I think the battery should survive.

Just my 2c. Correct me if I'm wrong.

edit:

Yes, deep discharge may reduce maximum capacity yet it is also necessary on a monthly basis to correctly show the state-of-charge. Since the poster had troubles with his battery drain, I assume it's more important that he has an accurate reading rather than worry about maximum capacity at this time. As for full discharge 2-3 times in a row, well, that's just to be safe (double hard-resets after flashing a rom).

Htc HD2

Guys, one simple question, I bought the hd2 2 days ago and since then, my battery life was not as impressive as everybody says. It lasted almost a day. And I did not use it that much so it would drain in such a short time. If you have any idea of why this is happening and what should I do, if there is something to do, to extend the battery's performance. Just to have the complete picture. When I got it, it had like 60% battery left. After it drained, I charged it for 6 hours with the phone off. I'm all ears and to some extent afraid of this because it is not cheap at all and I don't know what to do. Thank You in advance.

Charging

what i did with mine (i just received it today) i havent turned it on and put it straight to charge. now im not sure if this was a good idea but its still charging and hopefully it will max capacity.

everyone is through ideas about full discharge and charging when available. How is charging using the phone whilst charged via stock charger?

I’ve had mine for 4 days and was very disappointed with battery life.

Found this: SetupDialUpEnablerDisablerv0.4

sort the battery life right out. Now I can pull an email down every 30mins and the internet disconnects after 30 seconds.

The most useful app I’ve seen.

Please correct me if im wrong...

But a total discharge of a Lithium Ion battery Is not a good idea.

When you buy the device ANY device with a LiIon battery. its charged to 15/20 %.

And you should charge it after purchase. For 6 to 8 hours.

Tis will prolong battery life, and it will keep a consistent capacity.

After 4 / 5 charges the battery is at its normal capacity.

And ive seen many issues over here about the battery not lasting as long as it should.

And i am sorry to say but I use my phone ALOT. twitter, Data connection, Facebook, And exchange pushmail , And the phone will almost lasts two days

Before i do have to charge again.

And when i charge..

I dont charge it tru the USB on the computer. I use the charger that came with it.

And did you notice, often when the phone is hooked on the charger for 30 minutes it tells you the battery is full.

I leave it on there.
[HD2 General] samsamuel:
With Lithium Ion batteries they can suffer from both overcharging and overDIScharging. When they get down to almost zero stored power the Lithium anode can become poisoned with Lithium Oxide. Likewise if you over charge a LI Ion battery you create cobalt oxide within the cells, poisoning the electrolyte.

They also suffer from a fairly low charge/discharge cycle life, around a few thousand cycles or so.

As for the old 'charge for 8 hours before first use', that is a hangover from the nickle days, when batteries needed to be primed, and no longer applies.

Ah i dint knew that.

thanx m8 for the info
[HD2 General] samsamuel:
no worries. I should also add that our devices include circuitry to prevent too much over/under charging, so don't start panicking when charge drops to a few %. same with laptop batteries, when they report zero they actually have a few % left but won't let you use it.

one last tip...if leaving a battery in storage for more than a month or so , best to charge to 50/60% and not full.

HTC HD2 Battery

I have had my HD2 for a couple of weeks now. I charge over night (more by necessity than anything else!) but I still lose around 1% every 10mins (on standby...hence I need to charge overnight.

To give you an idea of usage, my data is nearly always on as i pull weather, Email (for 3 accounts) and Twitter. However, the phone is often in standby with only minimal use to read/respond to mails / SMS. less than 1hr a day of active use - no photo / vid. I do need to get my Emails etc though so turning off data is not really an option. All this said, I had the same configuration on the old HD2 and that lasted for 2 days so I know this is battery related as opposed to my configuration...

Now, the funny thing is that I had a HD2 before this handset but it went back as faulty after about 1month. That handset started out with battery performance as above but after a few weeks (i never measured the time) it began lasting for nearly 48hrs - i changed nothing, all data settings etc remained the same, the battery just got better. It started losing just 1% per hour on standby as opposed to 6%

My issue is that this new handset and new battery don't seem to be sorting themselves out with a longer life-cycle. I don't want to keep waiting becasue if i have a dudd battery I want rid of it ASAP whilst the store will still exchange it. Are there any guidelines as to how many cycles these batteries need to go through before they are at their optimum? Cheers
[HD2 General] kilrah:
Do you soft reset often?

On mine one thing that gets annoying is that after a day of common use I always end with something preventing the phone to enter standby. I haven't managed to find out what that is, but it regularly happens. I'll check regularly (mostly before going to sleep) what the standby consumption is, and if it doesn't go down to the normal 5-10mA (will be about 50-55mA instead) I do a soft reset and it's fine. Of course, it's pretty annoying to have to do that, but meh...

Your issue could be it, as when the device doesn't enter standby like it should it uses about 40% battery over 8h. When it does, that's ~5-8% for the same time.
[HD2 General] prankstarr:
No, dont reset often. But yes, it does eat 40% over night if not charging which is simply too much...if the standby consumption was less i'd be fine with the battery life - i dont mind only getting a handful of hours if I am watching a movie or playing MP3s constantly etc etc but when it is just idle, eating 1% every 10mins is excessive...

How do you check mA consumption?
[HD2 General] n3m3s1s:
i use my phone 2 hours a day brouwsing youtube on hsdpa/3g

about 30 min calling 20 text message and 2 hours of music

at the and of the day its about 45% so i am verry happy

its way better the my topax or experia ;)

[HD2 General] kilrah:
OK, so (if you can live with 60% battery left tomorrow morning in case it doesn't work...) try to do a soft reset tonight before going to sleep, of course charging it fully before, and not leaving it on charge overnight.

I use AEBPlus, the "battery information" screen shows consumption. I've mapped it to a hardware key.

To check standby consumption, press the power button, wait >30 seconds, turn phone on again and quickly (within 3sec) press the key to bring up the battery info screen.

I'm doing some tests today to try and track down which program causes me trouble. What I'm sure of so far is that it's an app that disables standby, and doesn't restore it when exited.
[HD2 General] prankstarr:
Hmm - that could be it then. It does seem to be battery usage during idle time that causes me a problem. If I take a 20min call I dont lose too many % - certainly not proportional to the amount used when in standby...So irritating! So basically when i am using my phone the battery drains as i'd expect but when it is idle, it drains way too fast.

I am currently on 58% after being at 100% at 8am. sent about 10 SMS but other than that not had the screen at all...
[HD2 General] prankstarr:
Ive isolated the battery issue (on my device) to having an open data connection. With nothing set to download automatically and then turning data off (If I have auto downloads set and then turn data off, it just starts up again annoyingly!) I lost only a couple of % during the night.

Whilst not ideal, I guess I just need to find some software that can manage the data connection so that when the phone is in standby, no connections are allowed, but once i wake it up, the auto downloads kick in. Anyone know of such a program? The HTC HD2 does a rubbish job of this in its native form and im amazed that actively turning data off (by holding down end key and selecting from the menu) does not really do anything (ie if data is set to download manually, then turning the data connection off is fairly pointless...and if data is automatic, then the instruction to turn all data off is over-ridden when the download schedule activates)

Sorry, bit of a ramble...long one short, anyone know of a program that can manage my data downloads and stop connections when my phone is idle? Basically to stop me having to go into every application that downloads and manually sync every time i wake the phone up. Cheers

PS if anyone knows how to get the phone to terminate all data connections for good until I allow them again please advise. I had an N97 and that did it quite easily - even if a widget constantly streamed news etc, if I turned of the data connection, the widget was stopped dead until I turned data back on. I currently need to go into every app (Twitter, Email, weather, bla bla bla) and set them all to manual download to be able to effectively terminate the data connection. I then need to go into them all again and set them to my preferred schedule during the day...grrrr....I hope i'm just doing something wrong becasue it is ridiculous on such a top end smartphone!
[HD2 General] prankstarr:
I turned off weather updates, twitter is now 8 hourly updates and hotmail downloads every 30 mins as opposed to as mail arrives...seems to have made a massive difference - i now get nearly 3 days...

Guess the data downloads / check for updates really can much your battery!!
[HD2 General] samsamuel:
I live right on the edge of 3g coverage, upstairs great, solid signal, but downstairs not. when im downstairs the 3g indicator flickers between 3g and edge, and the battery consumption is much higher than upstairs with a steady signal, or either floor with 3g turned off. the switching apparently murders battery life.
[HD2 General] r_southampton:
my experiences with 02 battery life

Interesting.

I've only had min 3 weeks, but I spent each of those 3 weeks in different places.

1st week I was at home, in a borderline HSPDA/GSM area, the phone constantly was switching as I moved around the house. Battery life was appalling.

2nd week I was "up north" on holiday (ludlow) - in an area which just had a fairly week GSM signal. battery life was still pretty bad - but I think better than at home. It was still a fail though, because on at least half the days the phone would die before the end of my day.

3rd week I've just spent in South Korea. 1st thing I do when leaving the UK is activate "no data". The phone was in a solid 3G area (that's all you get in South Korea) Battery life was hugely better. No problem getting two days out of it - which really is my bench mark for success.

Back at heathrow last night with approx 50%. Took 4 hours to get home in taxi (hold up on M3), used GPS for about 45 minutes (google maps) and did half an hour of web browsing. Phone at 5% when I got home.

Note - I've got the "Artemis v3.0" ROM loaded with Radio 2.06.51.07, and I'm using 02. I'd be interested to know other O2 user experiences.

is there a .cab that can manage our battery? or is there a post here with DETAILED instructions on what apps on our phones are eating up our battery?

an app that we can go into to set all settings for searching emails, facebooks, etc? or do we have to go through each apps settings and raise it up to your guys sugested posts of hour etc...?

would be nice to at least be able to use this phone for a full day. meaning listen to music all day. take average calls. (one - 2 a day) this is terrible!

i have done a search here for battery bringing up Showing results 1 to 25 of 1512 !!! and im a business owner and there is no way i'm going to read and search through 1500 threads... i have also read others replies to others who have aske dthis same question and people in forum being rude and telling them to search... well you just seen what my search brought up...1512 threads. with thousands of posts inside those!

so any guidance tips, threads, cabs anyone could throw my way would be greatly apprecated.

[G1 Android Development] gmadajczak:
I am developing my application, where voice should be recorded for later playback. According to official Android DevGuide I use AMR-NB encodec (only one available), but recorded sound quality is nightmare...

So my question - is this possible to encode sound using other (better) codecs, eg. FLAC or Vorbis?

Moreover, I am not native code developer - only android, so please explain me... Is this a problem to port LAME or full Vorbis to Android? I suppose yes, because nobody did not do it.
[G1 Android Development] daveid:
I would think the problem encoding to FLAC would be two-fold, one processing (slow little old things these phones are), and two storage.

It may be better (if voice is your target) to look into Speex, which is a variant of Vorbis/Flac designed for voice. Perhaps the person who ported FLAC to Android could help pursue this?

Check here.
[G1 Android Development] gmadajczak:
Thanks for reply...

And what about Lame - also OS codec for mp3?

So , am I right, that speex encoding is supported in Android? May I ask for advice how to use it?

I looked for speex... I think it is not supported in Android.
[G1 Android Development] daveid:
Speex encoding would not be natively supported by Android, neither is FLAC or MP3. The reason I suggested Speex is because it is open-source and royalty free, it also has a smaller footprint and might be less cpu intensive. Either option will require libraries to be ported in order to provide the encoding/decoding function. Speex would also be easier than MP3 because the native Vorbis libraries might be easily adopted to allow Speex playback.

Recently I installed official TD2 wm6.5 rom, the first impression is the weather animation effect in the home tab,

but this effect goes away if user changes wallpaper to one prefers,

so is this there any way to retain the animation effect, while user can still change wallpaper?

The "default" wallpaper, well, I thinik, is "no wallpaper" at all, since nothing shows up in the home tab background.........
[Touch Diamond2, Pure Themes and Apps] rumpleforeskin:
it depends on what rom you are using.

for example in dutty holygrail rom it is possible to select weather wallpaper and also choose a non animated wallpaper to be used too.
[Touch Diamond2, Pure Themes and Apps] pcgamer:
Well, I'm currently using official wm6.5 rom from HTC official website.

Since my TD2 is still under warranty, the best thing I can do for this matter is to find out if someone else comes up with such a program,

rather than installing an un-official rom my self.....

Great app. Create a cab so that you can have whatever wallpaper you want in both portrait and landscape. Best part for me is that it skins your taskbar and softkey bar to make them a part of the overall image.

On running the app select config and choose the profile that you need. In your case i think it will be 'wm6.5 Sense 2.1 All Tabs'

Good luck!

ok, but how can I install it?
[Touch Diamond2, Pure Themes and Apps] Dirk:
Ok, some information that may be helpful...and a long story. After reading the OPs post and digging deeper i notice that with my set-up i'm no longer getting the full screen weather animation that i used to have. Having been playing with all sorts of tweaks recently i thought i'd use the opportunity to investigate furthur. First up a hard reset.

Run through the usual Windows set-up and, yes, everything is working as it should be. Animation is present in home screen so i run through the settings, configure everything how i want and start installing my apps and tweaks. At this stage i haven't changed the Sense wallpaper but on returning to the home screen i see that the animation no longer works. Strange! I've been through this routine many times and would usually install my HDWall created wallpaper at this stage. So what's changed?

Well, the only tweak i've added since the last time i ran through this routine was installing the .cab for disabling the 1hr 02min flip clock 'feature' that is available on this forum. So, experimenting a bit i install my HDWall created wallpaper and sure enough i still have no full screen animation.

Hard reset...try again! This time i run through the routine, and of course the animation has stopped working as before, but before installing my HDWall .cab i go to the Sense 'Settings' tab and select a random picture to use as wallpaper under the 'wallpaper' option. Once this has been set i return to the same setting and this time i'm prompted to reset the 'default wallpaper'. Choosing this option i now have animation in the home tab again.

At this stage i install my HDWall .cab and, bingo! Not only do i have my 'all tabs' wallpaper working but i have the animation again. So to summarise, in my case at least, it was that one tweak which screwed it up for me. I'd suggest for anybody installing a wallpaper for themselves, whether it be by HDWall or BGForAll Tabs method to make sure the animation is working first, and if not to fix it using the method above. (Set random picture from options and then repeat to get the prompt to set 'Default Wallpaper')

Edit: BTW, this is an awesome tweak, thx to luxa44 http://xdaforums.com/showthread.php?t=582245
