how many hours is your battery good for?

[KurtTX]

Anyone heard of "wakelock", a situation where an app doesn't actually let the phone go to sleep even though you've put the phone into sleep or standby mode? I've asked before, but have been wondering about the special screen you can get to when you tap on the graph of your battery levels. At the bottom of that screen are several traces, two of them are "Awake" and "Screen on". I've been wondering what that is telling me.

I was recently reading about a situation where if the Awake and Screen On traces aren't very similar, such as the Awake screen shows much more time "on" than the Screen On trace shows, that's a situation called "wakelock". That's happening to me it seems. So, my battery is being used more heavily even though I have the phone on standby.

I went to Settings > Apps and checked a few of them. Some have a setting which indicates that it has permission to use the battery even while in sleep mode. I can't seem to find anything to turn off that permission. I can "force stop" the app, but then it indicates it might "misbehave". There is another button that says clear the cache...this might let me push out the app after I've used it.

Or better, maybe I can just reboot the phone a little more often.

Anybody have some ideas on this?

H4K -

"Background data usage"? Not really sure about that...I guess I'm not as concerned about data use against my limit as I am about things running the background that are draining my battery. I thought that putting the phone into standby mode, that apps wouldn't run. I realize that the phone has to be ready to alert when there's a call or message. But why do other apps have to run? For example, one of the apps I downloaded is Shazam that listens to music and figures out who it is. I've had fun with it, but it's not something I run very often. I checked and a System Tools permission setting is "Allows an application to prevent the phone from going to sleep." That's what it says. Now is that for the period in which I'm using the app, like trying to figure out what music is playing or is that all the time, even when I've moved to another location and it's been several hours later?

I've got an app to track my mobile data, and it has two operating modes: one is more passive, but less accurate; the other is more accurate, but drains the battery much faster. The two settings dictate how often the app is watching for data usage; the more accurate MUST be active while the phone stands by, since other apps may be using background data.

I've seen many apps that have similar setting options, and they often warn of the impact to your battery life to use those settings.

Also, ya gotta figure: if something is using data while the phone is on standby, then SOMETHING isn't standing by...

I use my phone pretty frequently at home on WiFi and at work to search for whatever or to look up a part a custome may need that I can't get. After my full day at work I still have around 50%. Unplugged at 6am good to go still at 5pm or so. The bb gets better battery life because of less intrusive apps keeping the phone active, and the much smaller screen.

The battery life is one of the weaknesses of this phone, and I knew that going in when I got it

This is how I use my phone:

100% charge at 6am when it is taken off the charger.
30 minutes streaming iHeart Radio in the morning before I clock in at the office (WiFi)
Light texting between then and lunch.
30 minute streaming iHeart Radio during lunch. During lunch, FB, Twitter, surfing, Tapatalk for forums (WiFi), light texting from end of lunch to leaving the office.
On the way home if I'm stuck in traffic I'll check FB or something else.

By the time I get home from work, I'm about to 50% nearly 12 hours later.

When I get to bed, with light use at home, it usually makes it way back to the charger at nearly 11pm sitting in the teens.

Since I'm on WiFi 90% of the time and with the 300MB plan, that's where most of my battery life goes. But I only use 100MB of cell data every month.

For emergency uses, I have a charger in the car and the HTC Sync cable hooked up to my laptop in the living room.

I am jealous of my wife's iPhone 4S who uses her phone just as much as I do, but will be at 80% by the end of the day. :-\
