HTC Desire battery life

Hi guys,

Just wanted to comment on the desire battery life and what i think.

When i got my desire about 2 weeks ago, i was over the moon at how awesome the phone was, but had one major worry about the phone...the batery life.

I did my research and noticed that alot of people with the desire were also dissapointed with the battery life...i couldnt get more than 6 hours from the desire, and although i was playing around with it alot (i wouldnt go more than 30 minutes without taking it out my pocket because i loved it) but i still fond 6 hours to be very dissapointing.

The first option i tried was app killers and task killers. I thought they were helping and my battery life was a little improved, but still not greatly and i was having connection problems due to force ending everything...i also got sick of constantly killing tasks everytime i would put my phone on idle.

I gave up on task killers and uninstalled them all.

The next option i went for was a little knownthing you do with your phone and your charger...it has been posted on this board, and if you google 'desire' and 'battery life' im sure you will find what i am talking about.

Its a set of steps where you charge your phone to full...then take out the charger and switch your phone off...then plug your charger back in with the phone off and wait for the yellow led light to turn to green..then take the charger out and switch the phone on, then when the phone is on put the charger back in....im sorry but if am confusing you, like i said you can find these set of steps on this forum and a quick google search will help you find it too.

Bottom line, I am promoting this charger-phone calibration, and i hae gone from my phone going down to 2 bars after 3=4 hours, to it being constantly green 20 hours later...currently my phone has been on since the last charge for over 28 hours...and i still have half my bars left.

I entirely promote this setup and beieve that it does wonders for your desire and battery life...I'll repeat it again, just to show you how much i like what this has done to my phone, i would play with my desire and it wouldnt last more than 6 hours...i used to fully charge and take the charger out at 8am and the phone wouldnt last til the late afternoon and die around 6-7pm....like i said, now after this setup, i havent charged my phone in over 28 hours and i have half my bars left.

Also, in addition to Proudest_Monkey, battery chemistry does indeed mean that the full capabilities are reached after a few charges. Not as many as the old Li-ion, but still a few.

Also, importantly, remember that when you get a new phone, you pretty much use it constantly! I know I do. You spend time checking it out, setting it up, listening to ringtones, hooking it up to the computer, installing contacts, testing bluetooth, making calls to check quality and brag(!) etc etc etc.

I.e. you rip the battery a new one for it's first few cycles!

So inevitably, with the above two points, and modern big a$$ screen smartphones, your battery initially will last not very long at all.

When I get my Desire, I expect the battery to choke within the hour!

If you've only recently uninstalled your app killer, bad battery life might be possible indeed.  Give the OS some time to sort things out.  Now that the app killer is gone, it can finally start to learn how to conserve power. 

Give it a week.  If it hasn't improved by then, you've probably got a bad app in there somewhere which is draining the battery. 

As for the iphone ... check out iphone-related forums to see how many (and which) problems they have.  We all laugh at the deathgrip, but that's just a minor thing really.  So far I haven't heard about Desires exploding or anything like that.

DeanoG that is the exact post i read and decided to try it...my battery life has increased by alot of hours thanks to that..an addition with the usual battery save techniques that are now habitual for me, like turning off internet when not in use.

What i found interesting was when my phone said its battery was full after charging, when i took the charger out switched my phone off and recharged, the LED light showed orange like it wasnt fully charged...it stayed orange for a good hour.

Battery life is not really HTC's concern.  So there's only our suggestions.

- Calibate the battery according to DeanoG's walkthrough
- Turn off WiFi, GPS and Bluetooth when not needed. 
- Set your screen to automatic brightness or a low setting
- use a static wallpaper, preferrably a dark one if you have an AMOLED Desire
- Don't use a taskkiller but let the phone's OS work out how to conserve battery
- Adjust the update settings for weather, mail (every account has an individual setting), stocks and such to get your preferred balance between battery life and getting the info when you want it
- If you stop using the phone, push the power button briefly to put it in sleep mode

In all fairness, the majority of smartphones need to be recharged every night.  As long as there isn't a massive leap in terms of battery technology, those big CPUs in today's phones will deplete a battery in a matter of hours.

My Desire easily gets me through the day without having to worry about my battery, although I could see how it can become a problem if you are constantly using the phone. 

I just got the desire and the battery trick just doesn't work for me!

1) I charged the battery with the phone on until the LED went green,
2) Disconnected from the charger and switched the phone off
3) Connected the charger again
4) The LED was still green and it stayed green

I tried this a few times. The second time, I let the phone run out of charge totally and started the whole excercise again but the LED was still green after the initial full charge.

I'm still getting 6 to 7 hrs max with minimal calls, minimal usage and just about everything turned off. Wishing I'd stuck to my iPhone now...

I would agree with all of the above except the use of a Task killer.  Read the various posts on this forum that show using one does not help battery life and indeed may even shorten it.
