Sprint HTC Hero :: Excessive Camera App Battery Usage
Jun 5, 2010
Ever since I installed the Android 2.1 update I have noticed a significant increase in my battery depletion when I am using the camera app. This is even if I am using the camera app for a very short period of time. For example, I might take three or four shots in the course of two minutes and my battery drain would be on the order of 7% - 8%. This is way more battery drain from the camera app than I ever witnessed when I was using it with Android 1.5.
I also noticed on the battery status screen, where you can see how much percentage of your total battery life that various apps and system processes are using, that the camera app skyrockets up to over 90% of the total usage every time I use it for a few minutes.

I've been searching all over this forum as well as the internet on how people are using their HERO and the battery performance they're getting out of it. I've seen answers from 9 hrs with heavy usage to 36 hours with minimual usage. That's about all the detail I've been able to find. (Maybe I'm just not good at searching?)With that, I decided to do a little tracking of my own. I logged my usage and battery performance over a 27 hour period and thought I'd share it with the community. Not sure if this is even helpful but maybe it'll provide some sort of baseline for others to compare against.I recorded the battery level in % based on the stock battery meter, the time I recorded the battery level and any activity that occured between the current time and the previous time recording. For example, between 7:00AM and 10:19AM the battery dropped by 10% and I had received 2 emails, 2 calendar reminders went off and I had surfed the web for about 10 minutes.

one of my other issues with my newly acquired X10 is its apparent heavy CPU usage. I would go so far as saying that the phone is close to unusable when it has just booted. So here goes my findings. I've installed a program called CPU Usage (quite logically) which monitors CPU usage for various tasks on the phone. Here is what I get when the phone has just been booted:
PID / Name / CPU Usage
954 / Sync Feeds/Checking Service/Setting Storage/Android System / 39-58% (No, I'm not kidding)
1054 / Download Manager/DRM /23-31% (still not kidding)
1171 / Face Recognition Service / 11-12% (not as bad, but still, why is it even there???)
The worst thing is that these services don't stop using the CPU - no, they keep on running and using CPU in the designated ranges, unless I kill them. So I go and kill them using another program I installed...................

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?

Soo running the froydvillain 1.4.4 tried different kernels. Would ask this on their IRC channel but I think they would lynch me :P The max stable I get is 748 was running it for like 10 mins :P (768 wont boot) Was running mostly 691 and now 614 . But dont know what will the difference in power consumption be. For example when playing with the phone and it will have to go to the 691 will it hold a lot less? Or its just a minor difference?

So I changed my DPI setting to 150 since in launcher pro I use 5 rows instead of 4 so it doesn't overlap etc. And wanted to ask if changing the DPI setting may affect the battery usage (recalculating screen) or CPU (making it slower) or the games will lag? etc.
Changed it back, I think was lagging and the text boxes were smaller not on the whole page. And the confirmations had green lines in the middle.
How I did it:
1. Root Explorer , mount R/W in system
2. Open in text editor.
3. Edit the build.prop line with ro.sf.lcd_density=150 and save the file
4. mount R/O and reboot
Still if someone knows something about the battery usage and cpu etc. So I know in future if I should play around with this one.

After pretty much a day of doing nothing on the phone except a few texts (GPS and WIFI were on all day), I got home and started playing with the phone. It got SOOOOOOOOOO slow (and I'm not nitpicking, I'm talking WinMo-hang-slowness....believe me, I understand a little bit of lag, but this was insane!) so I checked the Applications and Manage Applications. Now I know everyone's first answer is "get a task manager, etc" but I am not going to give into that, because I believe it'll cause more problems, or at least potential for more problems, by adding more variables to the equation if something goes wrong. I was looking at some of the applications that seem to be using quite a bit of RAM/ROM and had a question for the community:
The biggest 3 applications were:
Mail - 34.80 MB (34.25 MB Data + 556 KB Cache) and using 6.78 MB Ram
Contacts Storage - 4.09 MB total (all data) and 11.56 MB RAM
com.android.providers.calendar - 2.78 MB total (all data) and 11.02 RAM
What does everyone else's look like? I know I'm not going to be touching the Contacts Storage or com.android.providers.calendar stuff, but what happens if I clear my data and cache in mail? I have it hooked to an Exchange Server at work. What exactly gets cleared, and will that help with any of my lag? Do these numbers look pretty representative of everyone else's?

I've been running CM6 for awhile now and I love it. My only problem so far is that I absolutely hate the camera application. I much, much preferred the Sense take on it; so, I'm sitting here, wondering if there's a good camera application to replace the crap stock one.

Started with EXTBlue 09sept, had the phone freeze up a couple times when exiting sleep mode. Flashed a nightly over that, problem persisted. Also had it randomly restart a few times. From there, started over by wiping everything, and flashing a nightly (091710 I think). Still had the problem, found the so-called "6.1" update, wiped again and went with that. I still have the original problems, and now it's also freezing up on the camera screen. Otherwise happy with the performance and such, any suggestions?

I have a trendnet TV-IP422W Internet camera. Its all set up with an IP and I can view it from any PC.I use it for security.How to I view the camera with my hero? I do the same thing I do on my laptop. Just type in the web address and it ask for a password, and then the picture pops up. On my phone the picture will not pop up! I see that I'm logged in and can see my control panel. But the picture/video does not show its blank.Is there a special app for this?

When I send camera shots via email using HTC's Mail application, the photos are not readable by most recipients (except, interestingly enough, by my wife on her blackberry). Same photos sent by the gmail app are fine. The photos appear as attachments, but they cannot be viewed and when the recipient tries to download, a jpg that is only a fraction of the total size is saved and that file is not viewable either.

I'm super happy with my new Hero. But I use an external compact camera to make pictures.
Is it posible to connect an external camera to the HTC hero using a USB cable (and an app)?
This would be supercool when we are on the road without a laptop.

It worked fine for the first 3 weeks. As of a couple of days ago it is not. If I try to use it I get a popup that says: Sorry - The application of Camera (process com.android.camera) has stopped unexpectedly. The button below says 'Force close'. What could I have done? How do I fix it? Also my battery life at the same time has gone from acceptable to horrendous. Is this related or coincidence?

Anyone have a clue how to reset the image numbers for the camera. Every digital cam I have ever owned has this feature. Does the 5mp cam in the Hero allow this also, and how?

Not sure what happened exactly but the camera view is now a pink screen with no visibility. Phone is not modded so I doubt it's something I did. Is this the result of water damage maybe? Everything else is working fine and the water indicator hasn't changed.

Can someone confirm a picture taken with the stock settings in the camera can now be sent via sms?
On my end, it will show compressing the pic, the recipient never receives. (No I am not connecting via wifi.)

If you take a look at this post on gizmodo: Sprint Hero Review: Faster, Stronger, Uglier - Sprint htc hero review - Gizmodo.it claims that the sprint hero works better in low light than the GSM hero. Why is the GSM hero so much worse in low light?

I am having is when I try to send a picture through picture message I get an error saying message size limit reached, you cannot attach this to your message. So in order to send a picture this way do I have to either:
a. change my camera settings to lower resolution?
b. is there a program or setting to automatically send a smaller image and keep my high res photo?
Obviously I would prefer option B as this camera rocks and takes some good pics.

Today I took my Sprint HTC Hero to a Sprint store to upgrade to Android 2.1. In my opinion, I don't think it was worth upgrading the software. I really liked the options in 1.5 more especially the camera app. Any way, after getting home, my batter was almost dead. I pluged the micro usb cable into my Hero and attempted to charge it via an a/c charger. It started to charge from 10% slowly but then only went to 22% and stopped and stayed there for 2 hours. The back of my Hero was REALLY hot. I shut off the phone and let it cool and tried again. Same thing happened. I noticed that when you are using the phone and charging it in 2.1, the battery starts to die and it gets hot even quicker.Shutting the phone off and charging didnt help. What did and is still working, is putting the phone in Airplane mode, killing unnecessary running apps/widgets with the Advanced Task Killer by ReChild and then proceding to charge the phone.After leaving it like this for 30 minutes, the back of the phone was no longer hot and the battery percent went up from 22% to 33%, it is continuing to charge now.If you are having this issue, I suggest you use this method to charge your phone until the bug is fixed.This is such a pain because if your using Sprint Navigation in the car and your battery is about to die,you cannot charge it.The phone will remain on after using a car charger to charge it but the battery percent wont increase and it will get really hot.I guess we have to charge the phone before every use from now on? Android 2.1 is a lot of bugs. They made us wait this long for it and they have still failed to fix the major issues that were supposed to be fixed with this update IMO.

So, I rooted and installed fresh 1.1 a few days ago. The question I have is how is everyone getting better battery life, because mine has not changed, even a little? The speed has increased, but it's nothing to write home about. I guess I would like to hear from other fresh users to see what you have done to get more speed and better battery life and your overall experience with fresh so far. Don't get me wrong I love the look and it is faster. I'm just wondering if there is more that I can do to make it better?
