Well, as far as I know the faster you charge/discharge a lithium battery the shorter the lifespan. In the link I put up earlier there is a nice graph that shows just that.

High C (capacity) charging and discharging shortens the lifespan. Now obviously there are multiple kinds of 'slow' charging, but I guess slower is better within a certain range :D.

But that same link also states the charging/discharging rates might not be the biggest influence on the lifespan of a lithium battery. Complete discharges and heat have probably much more effect on the lifespan.

The output from my htc charger is 1A, the usb port I use puts out 0.5A I think. With a 1350mah battery (thus charging it around 0.4C) I don't think that'll be much of a problem.

Anyway, let's nudge this thread more back on topic. Are the more people with battery life experience of the Desire? Would be very intered to know if it can survive for a few days :D

Obviouly people play a lot with their new phone once it arrives, usually the first indications of battery life a always a bit on the downside.
[Desire General] Bandare:
The thing I like about phones like this compared to the iphone is that I can change the battery and keep going....
[Desire General] jannen:
Holding the phone the 'correct' way

Just got the Desire today!!! :D Great job from T-Mobile! Anyway... as it is charging Ive been going through the quick manuals.

It says that you should avoid holding the phone touching the lower back part (where the antenna is). Holding the phone the wrong way would result it using more power for the antenna = poor battery life. Wonder how much this really affects in real life?
[Desire General] evildead4eva:
thats not good. I always hold my phone by the lower back part when I'm using it :(
[Desire General] irkan:
naah dont worry this will not effect the battery life greatly, .... the reception might get poor though, but this shouldnt have huge impact on the battery life
[Desire General] O and O:
Anyone's Desire get hotish when charging ...?
[Desire General] Jabbypants:
Am having terrible battery life on this phone fully charged this morning at 8 ish, used it a few times in calls probs 40 mins combined, showing it me bro who now thinks his iphone is rubbish :P, having to charge it again now so far its not as good on battery as the Milestone i had, debating if to try it Nexus One style to see if it helps.
[Desire General] EroThraX:
My battery life has been getting better and better, had over 24 hours on 1 charge yesterday.
[Desire General] fooXeh:
Are you also using it less and less?
[Desire General] lukeyboymac:
I'm getting great battery life by turning off gps, WiFi and 3g and using low or medium backlight. Turning each thing on as I need it isn't really a chore. The battery does seem to jump from about 95% to about 60% amazingly quickly though.
[Desire General] scotch whisky:
The power widget is useful in that it allows you to easily change the brightness, switch wi-fi, gps, auto update and bluetooth on and off.
[Desire General] Jabbypants:
I don't use wifi have the brightness on the auto setting, don't use bluetooth or gps and disabled auto sync, only thing i leave on is 3g.
[Desire General] cez10:
and what are your results?
[Desire General] Jabbypants:
The results are it was charged this morning and is on charge again now.
[Desire General] RaptorRVL:
How does the animated background affect battery life?

On my Hero it makes a huge difference when I go into mobile network settings and turn off 'Enable always-on ...'.

Obviously the biggest direct effect on battery life is how much you use the phone.
[Desire General] sonandreas:
mines coming tommorow.

im a bit confused, when i get it should i just plug it in the charger and let it get to 100% or is it safe to leave it in for a while?

i wont get to play with it for a couple of hours has i have uni is it safe to leave it in the charger till i get back?
[Desire General] RaptorRVL:
Sure, it should be safe.

I'm just always extra careful with charging batteries when I'm not around (read: I don't do that). But mainly because I work with LiPo batteries a lot which seem to be a bit more volatile :). I got a bit paranoid probably :D.
[Desire General] aidanbree:
I have major issues with the battery life I am getting from my Desire. I wasn't sure how long I was getting from a charge as I have been plugging it into the wall whenever it was handy.

Yesterday I discovered an application called Juice Plotter. It charts the battery charge over time. There is also an application 'linked' to it called Juice Defender. It will turn off the APN (Internet connection) when the screen is off and only provide Internet access for 1 minute in every 15 to allow syncing to happen. I thought this sounded like an ideal way of saving power so I enabled it and have been monitoring the battery since.

I took the handset off charge this morning at 9am. It is now noon and I have 52% of battery remaining. In that time I have made 25 mins of calls and spent about 25 mins using the screen to sort out my contacts.

It would be interesting if others could chart their battery consumption for comparison....
[Desire General] shure2:
my mate has a nexus one and his battery life has gone from what you guys are reporting to at least a day, up to two days now that it has burned in...

give it time and im sure your battery life will increase, just let it run down to nearly nothing and then charge it to full
[Desire General] cez10:
for how long you have your phone?

apparently up until about 3-5th charge, the battery life is crap then it gets better,

have you played with the brightness yet?
[Desire General] aidanbree:
I have had the handset since Saturday. I have switched the brightness to Auto and I have also toned down the sync settings (Twitter 2 hours, weather 3 hours, Facebook 2 hours, Stocks off)

I used Sky News and BBC News widgets on my Magic and had no issues but I have just removed them both from my Desire to see if that helps any...
[Desire General] cez10:
just play around with it, and try to find satisfying results :)
[Desire General] Jabbypants:
The battery life is one thing that is making me think of sending it back tbh, i wouldn't say am using the phone excessively and the battery just goes to fast.
[Desire General] sonandreas:
so initially should i charge it to 100% take it out of the plug and let it get empty before charging?

just got it and want to know the best way to charge it initially and to maintain it.
[Desire General] Jabbypants:
Charged mine this morning average use and in half battery now, I know it can take time for it to settle so will see how it goes but I had it a week in Saturday.
[Desire General] chris.semple:
I had the G1 and so have had my expectations set for battery life. as soon as i got my desire i ordered a car charger and spare usb lead so i can charge at work :p
[Desire General] subharmonic:
I'm sure I read recently that these Lithium ion type rechargeables should be on charge initially for up to about 15 hours before initial use.

Don't quote me, but I'm sure I read that somewhere...
[Desire General] EroThraX:
Good luck with that, the battery stops charging long before that.
[Desire General] shaneaus:
I don't have a Desire yet. *wrings hands*

But, I have had a G1 since they came out. In my experience the only feature that REALLY chewed through my battery was WiFi. If I leave it enabled my battery life goes to 0% in a about 4 hours.

If I turn WiFi off I can go over a full day without charging (not bad for a heavily used G1).

I only write this to suggest to those with battery power issues that you turn your WiFi off. I haven't read many suggestions here regarding WiFi. However, on the G1 with WiFi enabled it is CONSTANTLY searching for a network and attempting to connect to ANY network it finds.

Same with GPS - it very frequently runs to update location and searches for satellites whenever there is a loss (like in your pocket while in your car).

I only enable those two features when I want to use them.

However, I leave my screen brightness at 100% and all the other features/syncs active/enabled.

I also leave my 3G off (as I'm using a T-mobile phone on ATT 3G doesn't work). So, I can't speak regarding 3G battery drain contribution.
[Desire General] RaptorRVL:
I think you might be confused with NiCd or NiMH batteries.

Funny detail, in the earlier WM versions the OS (registry etc) was kept in the RAM and not in the ROM. This resulted in a hard reset once the battery was empty. They solved that by putting in another small rechargable battery (a NiMH or NiCd, don't know anymore), a backup battery that kept power on the RAM (to put it simply).

For that reason the first charge of e.g. a Qtek S100 was supposed to be 12-15 hours or something. But this was only because of the NiMH/NiCd backup battery in there, not the lithium.

This will probably be the chip (somehere) that needs to be calibrated to get the correct capacity of the battery.

If you have bad battery life you can always try and fully charge it, completely discharge it (until the phone powers off by itself, perhaps even until it will not boot anymore!) and then give it a complete charge again. This cycle should at least calibrate the 'battery chip' correctly (if there is one, and lets just give it that name :D ). Can't hurt to give it a try, one charge/discharge/charge cycle isn't all that bad.

Installed software (e.g. battery widgets or other stuff) can also decrease battery life a lot. Same with active data connections, the amount of signal you have (batteries go empty faster in lower reception areas). Also programs that update your location regularly (e.g. with gps) cost a lot of battery, and the same with those facebook, twitter and other social network sync stuff.
[Desire General] evildead4eva:
my battery usage so far (at 50%) is being used by:

27% Cell Standby - No idea what this is....

26% Wifi - WOW Thats a lot...

25% Phone idle - No idea what that is....

16% Android System

6% display

What are "phone idle" and "cell standby" ?
[Desire General] EroThraX:
Phone idle is the power used to keep the hardware and software running at basal levels whilst you have the screen locked and the phone is left alone.

Cell standby is the power used to keep connection with the mobile phone masts.

Also the percentage is of charge used up to that point, not of the whole battery charge.

You can reduce phone idle power by reducing the number of background processes and the cell standby can be reduced by turning off the phone mode, ie use airplane mode.

You obviously weren't using the phone much relative to how long it was on for up to that point.
[Desire General] evildead4eva:
er its been on about 12 hours today and thats what its used. not a lot but i do leave it connected to the wifi at home and at university.

Dont have many background tasks running other than what looks necessary and nothing auto updates other than my email.

Expected the battery to be a bit better to be fair :/
[Desire General] Jabbypants:
I hope they sort the battery life out as its appalling atm my old phone the MIlestone was far far better.
[Desire General] Ape187:
keeping wifi on the whole time drains the battery fast. but 12 hours with wifi on and only 50% drain is not a bad performance, at least in my opinion.
[Desire General] Jabbypants:
My battery sucks i don't use wifi at all, nor gps, no sync, my brightness is on auto all i use on mine is 3g obviously and my batter life is appalling still.
[Desire General] aidanbree:
Well, I have narrowed down my issue to either the Sky News or BBC News apps. Since removing the BBC widget and completely uninstalling Sky News I have 'normal' battery consumption.

I have had the phone off charge for 9 hours and still have 50%+ life left in it!
[Desire General] pow:
Does anyone know if one can swap Desire and Nexus batteries- are they interchangeable?
[Desire General] leoni1980:
They both use exactly the same battery
[Desire General] C:Sharp!:
Hey leoni, didn't you have an HD2?

Can you say how the Desire battery life compares to the HD2?

Sorry if you already posted it and I missed it.
[Desire General] quicksite:
COLLECTION of TIPS for Extending Battery Charge: from AndroidForums.com

Some general notes re Battery Life: A couple of weeks ago in my travels across the vast internets regarding my Hero, I came across this very resource-rich thread at AndroidForums.com:

The Ultimate Hero Battery Life Thread -- A lot of good information from trial & error suggestions and testing. Seems this info would be helpful to any HTC Sense device, so here's a link:

But I made it even simpler: I compiled all suggestions and comments from 5 dense pages into ONE POST -- aggregating all.

One of simplest but overlooked fixes is to substitute a free Android Market widget for the HTC flip-clock & weather display -- the signature feature of HTC phones since they pioneered it on Windows Mobile Touch Flo phones 2 years ago: Search MARKET for "weather flip-clock" and you will find the most superb replacement, arguably better than HTC's, because every component of the widget has about a dozen or more skin variations, some quite dazzling.

The best replacement has a small cost, Cypha Flip Clock

The issue is how often the HTC flipclock refreshes the weather. But the replacement widget (almost identical) gives you full control over this, to once ever 1 hour, 2 hour, 3 hour, as well as simply manual refresh.

If I had an app to make screenshots I would show some of the truly beautiful variations people have made -- not just for other flip-clocks, but also for entire weather icon replacement sets, including full animations.

But the clock & weather widget replacement are but one example of ways to significantly reduce battery drain. Hope the compilation link above helps.
[Desire General] The_Stranger:
just to be sure, the mentioned Cypha flip clock is only a free skin, but does need the (paid) weather widget ($1,99)?

Bit weird that you can't specify the polling interval of the HTC weather/clock.
[Desire General] quicksite:
Yes, thanks for the clarification and/or question. I was going from memory vis checking to see the actual installations on my phone. But the whole thing is way simpler and bullet-proof easier than it sounds in print.

Between the widget and the skin sets for CLOCK and separate skin sets for WEATHER, they all integrate beautifully and with full controls and Menu Settings that make downloading skin sets and installing them, and swapping between them, so easy. Honestly, one of the best $2 i've spent in a long long time. For the price of an espresso coffee, you improve your whole phone's usability due to extended battery cycles... Plus beautify your phone. I'm a designer and I have to say some of the skins are far more elegant, sharp, and visually stunning than HTC's own already-stunning work. So here is a case where there is WIN-WIN... When I first read about it, i thought "oh. i'm sure this will look like some cheap knock-off" but was blown away by how perfectly this has all been programmed and implemented.
[Desire General] canonyau:
you can set how often the stock weather widget updates on the HTC desire in the "accounts and sync" settings section.
[Desire General] farukb:
good tip to save battery

disable the animated clocks....they simply kill the battery...use android's analog one (or htc's digital in worst case)
[Desire General] an430:
Use the black colour pic for wallpaper seems better than white or others
[Desire General] erklat:
Thanks for epic bump with not necessarily true advice as that holds up only on amoled screens.
[Desire General] tihimasmo:
Maybe you can save some by turning off bg data and auto sync. Put a sync button on homepage instead.

[G1 Q&A, Help & Troubleshooting] mistkäfer:
hi,

after some theme ****ed up my CM 4.2.15.1 installation I tried to to a fresh new install, but it doesn't seem to work.

First of all some information that might be useful, dunno:

DREA110 PVT 32B

HBOOT-0.95.0000

CPLD-4

RADIO-1.22.12.29

I downgraded to RC7 (Kila_uk-user 1.0 TC5 RC7 112931 ota-rel-keys) again and did the telnet-thingy to install the recovery image, which works fine - but here's where the problem starts.

I wanted to install DRC83_base_defanged (as the CMWiki says) from the recovery mode but it simply says "Installation aborted".

Also wiping, recovery etc. doesn't work at all. No matter what update.zip I want to install, it's the same every time. I googled for like 5 hours now and can't find any solution, please don't flame me if I was simply too stupid for proper searching, trust me I did ^^

The same thing happens to me when using the CM recovery and the RA one. Am I right that this can't be because I have no root? Because if I can install the recovery images, I should have root, right? please help me I'm getting crazy, trying to make it work for the whole day now :(

thanks in advance and sorry for my bad english and newbiness ^^

[G1 Q&A, Help & Troubleshooting] Firerat:
the only thing I can think of is one of your partitions has become corrupt

its happened to me before ( well truth be known I did a flash_image system /sdacard/nandriod....system.img , don't do that ;) )

here is how to confirm

from RA Recovery go to console, and type

mount /system

then

mount /data

and then

mount /cache

if any of those complain, then we are closer to fixing it

you need to erase the problem partition with fastboot

fastboot is part of the android sdk, you can hopefully find install instructions somewhere on this forum or google.

once you have fastboot setup, you need to get into fastboot mode on the phone, do this by holding the camera button when turning your phone on, you should see skateboards

hook your phone up to pc via usb

select fastboot on the phone ( fastboot should be in a red block )

then on pc

fastboot erase < the broken partition >

e.g. if system failed to mount

fastboot erase system

Hope this helps
[G1 Q&A, Help & Troubleshooting] mistkäfer:
ok the cache seems to be broken, now i just have to get familiar with the android sdk and how that fastboot stuff works:(
[G1 Q&A, Help & Troubleshooting] Firerat:
http://xdaforums.com/showthread.php?p=3083753

will help

and you can get to fastboot a little faster,

use back + power

but camera + power

and then back will work
