Battery Life

didn't the HTC instructions say to charge the battery 24hrs at first? i didn't do this (no time to leave it on for 24hrs... had to use it right away! ;)

i wonder if that might have something to do with the battery woes of many?? :confused:

that initial long charge setup might set the bar for the battery? just wondering... i don't know enough about battery tech... i'm a mech eng... lol :D

shouldn't the GPS only be running when you see the little satellite dish icon flashing in the status bar? that's what I wonder... :confused:

i leave it on, since i like having my weather location update on the fly... location/gps doesn't seem to even show up on the battery usage page...

That's what I would think too. I also have the weather widget running, but it seems GPS was running nearly all the time. The tower triangulation location works fine for weather.
 
There are always some apps running in the background,they are burning your cellphone battery,you should close them,i find the info here,good luck!
 
Here is my battery life over the past 4 days... last night you can see i left the phone off the charger at 88% and disabled background data use... this left a stairstep decline at 1.5% decline per hour until 8am it was 74%. For some reason with disabled background data use, my touchdown exchange mail still pulled in messages, gmail wasn't. No other app would work for me with background disabled.

No matter what I've done to conserve battery life it averages a 1% battery life decline every 6.9 to 7.3 minutes. In other words, it lasts approximately 12 hours give or take .5.

do you have an app that grabs data points for the battery life over time, or was this a manually intensive process?? if the latter...you're a patient man!!! LOL ;)

Dangerous! Some people have done this accidentally (forgot their charger or something) and the result: A BRICKED PHONE! Very risky.

These people must have amazingly bad luck with batteries. If running a battery completely dead once ran the chance of turning the device into a brick, there would be lawsuits and government investigations in the US. How many children each day run their Nintendo DS until it's dead? It's using the same battery technology you see in mobile phones.
 
Yeh, I don't think it will brick your phone if you run it dry, just that it will detract from the performance of the battery over time.

Although I don't act like it, technically I am supposed to be an adult, but I love my DS and plug it in the second the red right comes on. The possible horror of losing save data has me running for the nearest plug socket! :eek:
 
I've been unplugged for over 15 hours and still have 32% of my batter left. Sync on the whole time, live wallpaper, some wifi use, browser use, light phone use.
 
Took off charge at 8.00 this morning, have Wi-Fi on and Sync, live wall papers. Have also been messing around with it a fair bit and had a quick game of table tennis. now 15.00 and battery at 77%.

Not bad according to me.

Not bad indeed. But did you have APN on?

I don't seem to be having any problems, I have been using it a ton for web surfing, email, texting, taking pictures, video, etc. I have only charged it once since I got it around 3pm yesterday, and took it off the charger around 5pm. It is now about noon here the next day, and I still have 30%. I guess after getting used to a G1, I am not that picky. Seems about on par with how my iphone 2g used to be. I imagine once I get over playing with the phone, it will probably last a couple days with no charge, though I am totally in the habit of doing things like plugging my phone in when I am in my car, when I sit at my computer, and when I am watching tv, that it really is no big deal to me. And when I travel, I usually always have my laptop, so I always have a power source I can mooch off if need be.

Good for you. I am not sure if some of us simply have bad batteries or we are doing something.

I Have everything turned off , WIFI , GPS , Sync and Bluetooth and brightness set to auto.

I dont have any apps running in the background. Havent download anything on the new phone.

I charged to 100% last night and this morning I wake up with 27%. I charged it again until 9.00 am and after removing the charger it is back to 62% by 11.30 am

I used to complain about the battery for my palm pre but this is turnig out to be worse.

Luckily I dont have the 3g TO Edge switcihing issue and get constant 3G with 5 bars in my area.
 
MartinS said:
APN - mobile web?

If so, yes.
Click to expand...

yes, mobile web aka data transfer aka 2G/3G ;)

if so, very very impressive, as this setting on makes a lot of difference.

but still, it probably won't last full two days (30-36 hours), so you'll still probably charge every night.

Constant 3G might be worse than the switching :p

I dont think so. Switching should be a battery drain , being locked into 3G should not be.

Constant 3G surely is worse for the battery than constant 2G but it should be better than switching.

If this is what is going on they there is really some poorly written code somewhere.

Will try forcing the phone to use 2G and see if it improves. Thanks for the comment.

Just looked at the stats for what is using battering in the settings menu and it says that Display is using 60%

I have live wallpapers turned off and brightness set to auto.

Any idea what else in the display could be draining the battery

Well, Live wallpapers uses very little battery power. I've heard that auto brightness can be a small battery hog, turn it off and turn brightness all the way down unless you need it higher.

All I'm saying was that's what he reported. He did nothing out of the ordinary except forget his charger while at school. He put it on the charger the first opportunity he got and the phone was bricked. The Nintendo DS is not the same as a mini-computer these smartphones are. But hey, to each his own: If you want to run your battery dry repeatedly, that's fine. I'll keep doing it my way and be able to smile comfortably at a phone that 1) will turn on faithfully, 2) can go through 18+ hour day and still have 40% to spare :)

try turning off auto-brightness and set brightness down at about 20% or less... assuming you're not in a super bright environment where you need more screen brightness to be able to read it...

apparently auto-brightness might be worse, because it's constantly adjusting (and maybe even the sensor itself draws juice??)

@ MartinS: what's screen/wifi/gps/sync settings??
Click to expand...

Screen: first level of backlight on power widget.
Wi-Fi: on all day
Mobile network: on all day
Sync: all Facebook, Twitter, Gmail on all day

Have been texting, couple of calls, internet and playing games.

Just dropped to below 30% at 9.30 pm.
 
So, after starting this thread and getting pretty annoyed at my battery life, I called HTC. The guy wasn't that helpful. I jumped through all the hoops, just to show that I hadn't got anything running that was going to kill the battery. I understand that he had to check a lot of things. When I got nowhere, he told me to run down my battery to zero, wait until the phone switched itself off, then charge it again. I hadn't done this since after its first charge. I agreed to do that, but got a case number, because I was sure I'd be calling back to try to get a better battery.

So, I turned on GPS navigation and Pandora and killed the battery over the course of around an hour (from 22%). I took the battery out, left it sitting out for maybe 20 mins, and recharged it overnight. I was shocked to see that it actually helped a lot - now I'm able to use my phone throughout the day (8-5) and have around 50% battery at the end of it. Nothing like the first day, when I tried to show it to some friends at 2.30PM, just to have the battery die in mid Google Goggles demonstration.
