Display battery issue

[dsu]

My battery drains ready and if I unplug it at 6am it won't last me past 4pm. I use my phone lightly mainly just texting. On the battery usage app it says 92 percent beside the display. I use the lowest setting for brightness. I currently have andromeda 1.0rom on my rogers captivate. Previously I had the cognition 3.04 but still the same problem. I've tried deletingbattery stats through recovery menu. I also tried calibrating the battery. Wifi is used instead of mobile network. Gps is off. Bkuetooth is off. Emails set to push (i read somewhere that push is more energy efficient than autosync)

Could this be a hardware issue? Any idea on what I should do about my problem?

How much actual usage does your phone get? 10 hours of battery life is abnormal unless you have like 4 hours of screen time.

What do you mean by this? How would I check?

Well you can check your screen time by going into the battery stats then pressing Display.

Other than that, it'll tell you how long you've used voice calls and stuff as well.

ohhh,the only problem with that is that I restarted my phone 2 hours ago so I dont have the full data for this charge.

You can check your actual screen time by tapping the "Display" entry in the Battery Use screen. That will tell you how many minutes your screen has actually been turned on.

I have a similar problem: My screen seems to use a TON of battery power, and it's almost always over 93% or for battery draw. I don't see a huge difference in power use between minimum brightness and automatic.

I tend to use the internet and text/email heavily, but I'm wondering if even that could account for the insane battery use. Today, I unplugged my phone at around 6:40 am. By noon it was at 1%.

Before I started using custom ROMs, I could usually make it to 4 with what I considered heavy use. Now, I can't make it past lunch time. I've done the battery calibration, bump charging, deleted battery stats, and discharged the battery to shutdown before charging fully. The screen power draw has persisted through two ROMs and three kernels. I'm wondering if my usage pattern has just changed this much, because I can't find any hardware or firmware issue to account for this.

Do you think a new battery can fix my issue our no?

Yea our problem is pretty close, if not then identical. I'm using it moderately and its at 10% right now.unplugged it since 6am. Ive tried a lot of different methods to try to fix my issue to but still nothing.

A few minutes ago, I checked my battery use. Here's how it played out:

Unplugged for 58 minutes
Screen on time 28 minutes 3 seconds
84% battery left
92% of power used by the screen

Do these stats look normal for screen power draw? This is what I'd call heavy use (I've been reading forums), but should the battery be draining this fast?

I have no idea. thats what i want to find out. heres mine...
66%battery
9h27m52s since uplugged
display - 76% --- time on: 1h23m22s
wifi - 13% --- time on: 9h26m51s
cell standby - 8% --- time on: 9h27m42s
phone idle - 4$ --- time on: 8h4m29s

any idea? i slept at 3am and woke up at 930, but didnt charge the phone.
Before i slept the phone was around 72%, and when i woke up it was around 70%. from the time i unplugged it to the time i slept it went down from 100 to ~72% under moderate use.

are these numbers right to you?? the only thing i am worried about is my display consumption that seems to be killing the most. Also, wifi uses less battery than 3g/edge right? so i shouldnt have a problem leaving that on. even when im not using it.

That seems like regular battery life there. If your phone is reading your battery accurately, that means you would be getting almost 30 hours with pretty decent usage before it dies.

Here is another update. tell me what you think.

29% left
13h13m49s since unplugged
85% on display -- 2h 52m 44s
7% on wifi -- 10h 7m 44s
6% on cell standby -- 13h 13m 40s
3% on phone idle -- 10h 21m 4s

It doesn't even show me my voice calls and 3g usage. weird.

also, do you know if the timestamp on you batterystats.bin is supposed to change? is that normal? or does it mean my batterystats is wiping on its own?

I believe the timestamp is supposed to change with batterystats.bin being updated. The only way it is wiped is if the file is deleted completely.

And still, that seems about right to me. 3 hours of display is a fair bit. In a regular day I normally see about 30 minutes of display usage.

wow really? 30 minutes of display is like bascially not touching the phone at all.
Is there a reason why the battery usage does not show my voice call usages and my data uses (mobile data, not wifi)

I feel like my battery life is... Less than ideal.

I'm going to be doing a few tests, unfortunately, it seems like my battery dwindles very quickly in 30% chunks, according to JuicePlotter.

One thing I've noticed that helps a lot is disabling your data network in general, unless you plan on using it.. You can still send/receive texts and phone calls, and that's primarily what my phone is for. It helps save a significant amount of battery.

Unfortunately, because I am waiting for some emails i cannot turn off my data network. my data network is on when i cannot get a wifi signal. I also feel that this battery is not ideal. I cannot last for more than 10hrs unplugged time if i unplug it when i wake up. if I unplugged it before i slept it would be a different story for obvious reasons

again, any help is and will be greatly appreciated

Here's more stats (running Cog 3.04, Gen X 1.14 theme, stock kernel)

Unplugged for 16h 22m 40s
69% battery life
38% display: 41m 24s
23% voice calls: 29m 39s
21% wi-fi: 16h 22m 40s
13% cell standby: 16h 22m 40s
7% phone idle: 15 h 41m 16s

It seems like I can easily get around 40 hours of battery life here, but obviously I'm in the light usage market, although I do use my phone to make a lot of calls.

In the past, I found that running different modems and kernels (specifically DG's Firebird 2 kernel) drained my battery life faster. While I loved the extra power and features (Voodoo sound specifically) the drain on my battery life was not so hot (see above specs but my battery percentage would be closer to 30% than 70%). I recommend returning back to stock via ODIN, see what your battery life looks like, then adding a custom ROM, seeing what your battery looks like, then kernels, then modem. That way you'll find the source of your problem. If your battery still drains heavily on stock, try a different (possibly new) battery. If its still doing the drain, it's gotta be hardware related and you might need a new phone.

Interesting, I was at 18% battery after 2 hours 45 minutes of screen time. 93% screen, 3% wifi, 2% cell standby. I'm starting to think that a) the screen really does just use a lot of power and b) my battery is becoming deficient.

I was actually thinking about returning my phone back to stock, unfortunately i do not know how to do it. I came across the odin3 one click downloader, but i was told by some to not use it since it is for AT&T. I am from canada and I use Rogers. Any ideas?
