Default camera eats up battery even when off?

I've noticed a few people have had the same problem. Notice to charge your phone, check battery usage and it says "camera a million percent." Best advice so far is to turn your phone off then back on and it goes away. But this happens every time I use my camera. Am I gonna have to turn off my phone every time I'm done with the camera or is there a way to make this stop happening? It's only a recent problem too. When I got the phone a few weeks ago, I had no problems. If the battery was low and I checked why it'd show display and cell standby and phone idle. It's just been the last few days that it started showing the camera.

BTW when I press on it (where it says "camera a million percent") for more details it says "turn off GPS" why do I need to turn of GPS to make my camera stop draining the battery or is that totaly unrelated advice?

Problem solved. Incase this helps anyone, the sprint guy said to get an app that force closes things. He said that android keeps everything running after you use it to make it easier to multitask so get one of those apps and JUST use it on things like the browser or the camera and only when you're totally done with them. He also said that when you check battery use, it shows everything that used the battery since the last time you charged the phone so if you force close the camera and it still shows up in the battery use list thing, it's not saying the camera is still open, just that it was open and this is how much power it used but is not necessarily still using. He said when you charge the phone again, after you unplug it, the battery use list starts over. I'm new to droid phones so I didn't know any of that. I'm assuming it applies to most droid phones so I guess I won't try to figure out how to delete this thread incase other people are still having that problem.

Welcome! This has happened to me a time or three, and below is my best explanation, the logic is sound, but there is a chance I am not 100% correct

What's most likely happening is that when you leave the camera app, it is done with the home key and not the back key, that seems to keep it running in the background. It tells you to turn of GPS, because geo-tagging is probably turned on, and whenever the camera app is open, the GPS receiver is active.

I do the same thing with System Manager, Because my phone will open the gallery and everything else when i start my phone even though i never use any of those, on the off chance that i need to get into my gallery starting it up isn't going to use as much as leaving it on for 12 hours is going to. I don't go crazy on the "task killer" portion of system manager like i used to, but when i use my phone for nothing else but...ya know... a phone. I don't want to see my camera, browser, and gallery running when i haven't even used them since the phone started. Yea.

I have a slightly different situation. I noticed that the camera is using 100% battery while on the charger, every time. When I take the phone off the charger and check what is running with a task killer the camera is not on there. I always use the back button to close programs, not home. It does this every time I charge the phone. Also, this started recently for me as well. Within the last couple of days and i notice that it is draining my battery.

I had the same issue a couple times. I realized I would take a picture, share it, then hit the home key which left the camera still active and hungry for power. I now make sure to back out of everything before pocketing my phone.

My problem is a little different and I have outlined it in a thread of my own but here is a brief synopsis anyway. Basically, the camera app on my phone will use the battery A LOT, but only when I am actively using the app.

Once I stop using the camera app on my Sprint HTC Hero, it stops consuming the battery. It uses a ton of battery juice, though, even if I am only using it for a minute or two.

So whats wrong with this? I mean, I know it should not.. but the camera in any phone is a battery drainer (specially when its a 5MP one with autofocus). Furthermore, the camera app is really slow, which means it uses a lot of CPU/battery...

What is wrong? Well, I was just putting in my two cents about the problem. I was not complaining about it. It is certainly not a deal breaker as the trade off seems to be much improved picture quality after the Android 2.1 update.

Simply stated, my handset's camera app did not use NEARLY as much battery power before the Android 2.1 update. However, as stated in my previous thread, it produced much grainier pictures that were also greatly saturated in color tones when I had Android 1.5. The added clarity and improved color balance, for me, makes it totally worth it. I am very happy that I can take great shots now, even at the sacrifice of more battery power.
