Battery Guide

yes just 100%, it doesn't matter if you leave it on for longer, it just isn't necessary to leave it on.

i also thought that is what you are meant to do, but when i wrote this i looked it up more and it said to never fully discharge a Li-ion battery (the odd full discharge won't hurt it but isn't necessary and will hurt the battery if you keep doing it). apparently it is because this was the procedure for the nickel batteries and people think it still helps to condition the battery.

ps. i can get through a day using 40% battery life and i haven't used all of the tips lol, not all are suitable for me. i put my phone to charge while using to start with, but i didn't suggest that here just because some people are afraid of the old rules lol so easier to just say 100% before you use on the safe side. did the same thing with my k800 and it can last 4-5 days without a charge and it is 2.5 years old

My phone is 1 month old. I am not happy with the battery. Last night I had 100% at 1130 pm. I turned off everything in the taskmanager. No wifi, bluetooth or Internet going. When I woke up 730 am the battery showed 87%. So in 8 hours I had lost 13% just i standby mode. This means it will have about 61 hours standby time.

Nothing like this.

Standby time:

    * WCDMA: Up to 390 hours
    * GSM: Up to 490 hours

Is this normal? If I use the phone a lot it only last me for half a day.

I have installed WMLonglife to see if this could help me. It maybe helped a little bit, but I still need to charge the battery too often.

i use under 10% a night. maybe you have programs running in the background.
download "touch x taskmanager" and after you install it, there will be a little symbol in the top right corner, click it and that will show you your running processes, close them all by using the box with the x's at the top left.
hopefully that is why your drain is so high.

i am on my 3rd day right now with 35%, going to try make it to tomorrow without charging lol

lol nope. had it on GSM only, and a few times turned data connection on, when i was out and wanted to surf. i did use wifi too. made a few calls and load of texts.
i'm really going to try make it to tonight/tomorrow morning with it lol

If 90 minutes talk used 20% then HTC is correct. 100% battery use would be 450 minutes. I use my phone to stream TV at night when in bed. Keeps the wife happy. She likes it quiet and dark. I need it to fall asleep. I can stream 1 hour of tv, around 200MB. So I have media player running and my internet connection open at max. I also have closeX process running which acts like a sleep timer and shuts the media player off after 1 hour. In the morining my battery is around 80%. So I don't find these figures too far off.



Yes using Touch X or Duttys task manager is much better. But for some reason I can still open the regular task manager and find apps listed as running.

Correct. 90 minutes talk and about 4,5 hours standby took almost 80% of the battery. The battrey indicator showed 20%. So something is serious wrong if you ask me.

I will try those things you wrote.

give them a try and get back to us. if it doesn't work back up everything do a hard reset which will wipe everything and reboot your ROM from scratch then test again.

Gotcha. It used 80%. It didnt have 80% left.   Going back to bed to stream video.
