Mine only uses 4% in 8-9 hours with data sync and weather running.??? First time yesterday night that I placed my Desire into airplane mode and used it as an alarm clock to wake me up. Battery still shows 100%!
can any HTC Hero users compare the Desires battery life with the Hero?
Thanks
I went from a Hero to a Desire and I frankly haven't seen much change in battery life.
Like people said above, once the battery has been charged a few times, it easily lasts the whole day. To help it last that little bit longer I always have gps and wifi off unless I really need them and have "always on internet" turned off.
Hi
Just wondering anyone is having the same issue as me?
Basically if I am in my car and have the phone connected via bluetooth to my car kit (just for calls not music or anything)
And I have GPS switched on and am using Googlemaps to navigate.
I have the phone on charge via a 5v 1A cigarette lighter USB charger, the battery still loses charge! It loses charge fairly slowly, but if I take a call then it will drop by a few %.
I can't understand why the phone is not receiving enough charge to cope with these demands, I hate to compare it to my iPhone, but this never had the same issue with similar demands on the power.
Anyone have any ideas, or is it something I'll just have to put up with?
Thanks,
Bruno
i think the charger problems when doing stuff like google maps etc stem from a low amp car charger. the standard desire mains charger outputs at 1a (1000ma) where as most 'cheap' generic micro usb chargers will only output at 500ma. obviously when your using high power stuff if the power coming in is less than whats going out then your going to have a problem/ i'd probably get a decent high output car charger (such as the htc one or this belkin one Belkin Micro USB charger F8Z445ea Cheapest on eBay (end time 17-May-10 15:03:12 BST)
then you shouldn't have any problems. not had any so far with the gps, google maps running and music playing!

Because your phone is consuming more power than your charger can provide.
The phone battery is rated at 1400mA, that's 1.4A
Your charger can only provide 1A so your drawing more current and the charger cannot keep up with the demand.
Is it the official HTC car charger?
Atm mine says 33% for cell standbye, 24% phone idle, 27% android system and 7% display. Does that look ok?
Did some tests using a power supply and DMM.
Regardless of what the phone is doing, Switched OFF, in Nav mode, Screen OFF or ON, apps running or not.....
The following applies......
The Phone only ever draws 400ma from the supply when on charge. So if the tasks in hand draw more than 400ma, the battery will not charge and in fact eventually go flat. I had a calibrated 5v supply to the USB, if the voltage is nudged upwards to say 5.2V the current supplied does increase very slightly. May be mileage in increasing this, but dangers are associated and not recommended unless more info can be obtained on the charger circuitry in the phone
Bad News for a long trip using navigation and brightness on high....
i found this tip from another forum and it has helped me a lot! i think u guys should try this.
settings > wireless & networks > mobile network (2nd one) > enable always-on mobile
disable the above setting (by default it's on). i can have my emails push, auto update widgets, etc and my battery still lasts!
let me know how it goes for you guys.
where are you getting this info from? if it was true then a generic 500ma usb charger and the standard htc charger would charge at the same rate, which they dont (4.5 hours using generic from dead and 3 using htc from dead).

it does, but at the same time highlights the big problem with most HTC Android devices... the cell radio is the biggest draw even when idle....
guys on the Incredible forums are claiming 2 days on a charge when they turn off cell data (of course, you lose the push notification if you're not near wifi so it's kind of silly, but I guess it works for some that don't need immediate notifications)....
for some reason HTC just can't seem to design a decent radio that is efficient for power consumption, let alone have decent reception compared with some other devices out there... and it's been proven many times - signal strength (in dBm) on HTC handsets is offset 5-10 dBm weaker... got to be their antenna design or something... they just can't get it right...
