battery-life screenshots

Am I the only one who thinks these screens and the comparison are a waste of time? Correct me if in wrong but these percentage relate to the battery used, not percentage of time since unplugged. Therefore just because a display percentage is high means nothing. I'd be more interested in knowing how long your screen is on as that is the biggest battery killer, I doubt the people with 24hr battery lifes have their screen on for more than two or three hours tops.

that is exactly what i always wanted to know..every single one of the hundreds of battery threads talk about how long the phone last from a charge and show screen shots like the ones in these threads...i have posted in other threads and in other forums trying to find out how long the screen has been on...because for me i dont talk on the phone too much at all..hardly ever...so the time the display is on is pretty much how long the phones last for me with the total of my use......

as of now i did a full charge 1 day 8 hours and 13 min ago....display has been on for a total of 5 hours and 7 min...

i dont know what is normal for the total of a display being on because i have never seen any threads talking about it and comparing
(also i think that is the longest the screen has lasted yet...first couple of days was 2 - 2 1/2 hours...then eventually 3-4...then a little over 4..i guess its getting better as time goes by....just updated to froyo 2 days ago and this being the first full charge cycle i guess its pretty good...although right when i update it went from 30-15-5 % within 20 min

this is with auto brightness,status updates pushing updates for twitter, facebook, and myspace, panoplanet live wallpaper, 10 min of calling, 10 text messages, 15min of net surfing, and watching two videos

The Droid X is advertised to get 220 hours of battery life if you keep it in standby, so I agree that posting the time unplugged isn't terribly interesting without qualifiers. My stats have improved significantly, and I suspect it's due to using WiFi rather than 3G, among other tweaks... I tend to get lousy reception in the catacombs of the hospitals, and that drains battery life quite quickly. (Constant data connection so Google Voice works, which helps when all I can get is WiFi.)

Code: 
40% Battery life remaining, 12h 57m 48s since unplugged
40% Display (2h 6m 58s) (Left on minimum brightness during the day, Auto when I got home)
17% Cell standby (25% Time without a signal)
12% WiFi
12% Phone Idle (10h 50m 49s)
7% Dolphin Browser HD (14m 49s)
5% Android System
4% Android OS
58.7% Running (Time spent without sleeping: 7h 44m 48s)
 
This is with probably about 5 hours of web surfing, downloads and uploads, 2 hours streaming Slacker over BT, another 1.5 hours Slacker through speaker or headphones, plus some other stuff on the phone like screen shots, customizing, and playing around with a couple apps, and couple quick calls (about 15 min total).

Phone was at 10%, it died about 20 minutes later.

Basically I get close to 13 hours of pretty heavy usage. On days when I'm not at home messing with my phone all day my battery lasts a lot longer.

Before Froyo, I was getting about 10 hours of heavy use.
 
No SS, but
Battery @ 10%
-17h30m unplugged
-44% Display, 4h1m turned on

Nothing else really interesting except screen on time IMO
 
Battery @50%
- 17h 3m 25s since unplugged
- 35% voice calls
- 19% android OS
- 12% phone idle
- 9% cell standby
- 9% wi-fi
- 9% display

This is @ auto bright & wi-fi always on.

Maybe try wifi on, only when you're actually using it. :D

Wi-fi is more of a test as OP said "always on" actually saves battery. It's hard to make sense to me but I gave it a try. Anyone agree on leaving it always on? As I ample power to go through one day, it's not a big deal either way.

I hinted at it earlier, but I leave it enabled and have it set to never disconnect. My reasons are for better battery life (see below), and greater reliability (WiFi has better coverage than 3G, and Google Voice text messages can work with either). Plus faster internet speeds mean less waiting around, so less annoyance, less time for the radio to be transceiving data, and sooner that I can turn the screen back off.

Apparently the phone prefers 3G when the screen turns off, so it'll disconnect from WiFi. This drains your battery in three ways. First, WiFi uses less power than a 3G data connection (3G is disabled if WiFi connects). Second, if the 3G signal is weak the radio power is boosted, so the difference is even greater if you get poor reception in your area. Third, right after you turn your screen on, WiFi is reenabled, so it has to reconnect (which consumes a fair bit of power), and you have both 3G and WiFi running while it's connecting, rather than just WiFi or just 3G.

Sounds like it makes a lot of sense. My only question is by setting it NEVER it will be on when I'm not in the known areas - doesn't this drain extra battery? I guess it depends how much time you are in or out of known areas, too.

How do you set it to never disconnect, I can't find the setting for it. I remember setting it to never disconnect when plugged in, but I don't remember how I set it. That should increase my battery life because my phone signal sucks at my house.

In your Manage WiFi Connections menu, click the hard menu button and it has an "Advanced" button. It's in there. NOT intuitive at all!
 
My understanding is that wifi (which is usually a strong, local signal) takes less power than 3G. When I connect to wifi, the 3G in my status bar disappears.

Why would it use less power to have wifi on, but never use it?

My gut tells me you guys are mistaken.

Maybe you guys are mistakenly assuming wifi auto-connects to any available signal. It does not.

FWIW, I use Y5 - Battery Saver to manage my wifi. My wifi is only on in places where I have remembered connections, (home) and I have great battery life.

From best to worse in regards to battery life:
  1. Don't use any data connection
  2. Use the data connections for only a few minutes every few hours
  3. Use WiFi if it's always connected
  4. Use 3G if it's always connected
  5. Enable both and let the phone pick which it uses
  6. Leave 3G or WiFi on when it's not in range of any saved networks
  7. Leave 3G and WiFi on when neither is in range of any saved networks

I forgot to mention that by "ubiquitous WiFi" I wasn't talking about random open networks. I go from my WPA2-PSK home network to the hospital WPA2-EAP network with maybe a minute of downtime between them (they might overlap). I've also added the open access points provided by restaurants in the area, and disable WiFi if I leave downtown.

My point exactly. You've added connections to your phone and use wi-fi to actually use them.

I admit I've only skimmed a few of the posts here (so forgive me if I'm missing something), but that's a far cry from turning on wi-fi, but having it set to never connect.
 
Are you guys using the Settings->Battery Manager->Battery Use, or some battery app? How come your result shows so many items and mine only shows Display, Cell Standby, and Phone idle?

For Battery profile, do you use smart mode or battery saver mode?
 
With Froyo it shows more things like in the above screen shot. Maybe thats why. I'm assuming tho since they didnt say whether or not they have Froyo.
 
Does anyone's battery meter work on finer increments than 10%? I wish it would just for testing purposes.

likewise, on the wifi thing. I use mine whenever there is wifi near around that i know about. And sometimes temporially just to see if there is one.

wifi will use less power than 3g (think of it this way, less distance to cover = less power needed). But keeping it one when you are using 3g/4g is just going to use that wifi power to constantly try to find a connection. it never turns off, unlike the GPS settings.

I started using "Y5 batter saver" this week and so far it's doing a good job. It automatically shut off WiFi when I'm not at home or office, i.e., when there's no known WiFi to connect to.
 
You guys might try charging a couple hours longer than it takes to get to 100%.

I charged and unplugged before going to bed. When I got up I still had 100%, put in 8 hours at work, got home, updated my apps, installed a couple and deleted some email and hours later still had 90%. I had no calls today. At 21 hours unplugged I still had 90%. (I'm at 80% now, 23 hours unplugged.)
