Found a way to extend my battery life, weird though

I was just wondering if someone can test it out as well. Ok my situation is that I used to put my phone in standby with nothing on such as my phone looking for email every so minutes because I set those to manual. Don't have any programs running as well. Well when I would wake up my phone the battery would be drained substantially. Example of this was I had my phone at 100 percent charge, went to bed and when I woke up my phone wouldn't wake up so I popped out the battery, put it back in and 28 percent battery. I was like wtf I'm not even using my phone. Well I noticed that if I turn on my bluetooth the battery does not drain like it does when it's off. Kind of weird but I've tested this out and it works. I am using Shaps: 4.31 ROM English and Radio: 1.27.15.32 (I remember reading that this radio was a BETA but I've been using it for almost 2 months maybe more) I'm thinking about switching my radio for another one. Just wanted to let you guys know it's weird. I find myself keeping my bluetooth on all the time so the battery doesn't drain as fast. I can actually get a full days use of my phone now. Weird huh?

Yup - weird - I find exactly the opposite. I turn off my bluetooth when I do not specifically need it to SAVE my bettery.

I have an even different situation. Since I constantly use my bluetooth headset, I leave Bluetooth in the "On" mode all day and night. The thing is, I charged my battery until it was at 100%, left it on the counter (not charging) for the night (approx. 8-9 hours) and when I woke up, it was at 98%!
Keep in mind, Bluetooth and WiFi were both turned on. Good stuff.

If your battery is draining over night when your not using it, it's probably because you have something running in the background. You might have "closed" something and then it was actually still running. Try installing AlltheWay's task manager. This aids in making sure nothing is running in the background.
I'd upload the cab but I'm at work and don't have it.
Getting a full days use out of your phone is NOT something you should be happy about. I get 2 days with Wifi and Bluetooth use.
@ kamilzmielca: Your Wifi connection goes to sleep when your phone does, so your Wifi actually wasn't running over night.

yeap, mine does the same thing, thought i was crazy, but with bluetooth on i save battery life.

Yeah man I thought I was going crazy also. To the previous poster all the programs are fully shut down. I've had many pda's (windows) and I am familiar with how they work. I fully shut everything down and then put it to sleep. Bluetooth seems to be extending my battery. Like I said before all my email I have setup in the phone I set so I manually have to send/receive instead of it looking for it at a predestined time. Nothing is automatically connecting (as in programs) I'll look a little deeper, it may be due to the radio version on my Kaiser. Any input on this guys?

you could try to measure the actual battery usage with "BatteryStatus" with and without bluetooth. Would be interesting to see the differences.

Maybe the bluetooth is slowly charging the phone when on through the radio waves! or some mad theory
I might give this a try as my phones lasts about a day atm

My phone lasts about a day at the most with full battery charge. 2 hour of talk time plus the other stuff I usually do. 2 days is crazy maybe you don't have as much programs on your phone so you use it less. (to the previous poster) I will get that battery program and do a test to see the difference.

another crazy idiot here: bluetooth on also gives me a longer battery life...
is this a joke from HCT??????

Your not crazy man! I'm doing a test now with BatteryStatus and notice that I actually get a lower mA reading with BT on. This is messed up.
When I fist read this thread I though everyone was nuts, now I think I've just entered the rubber room. lol

I could imagine, that some application or some part of the operation system is trying to communicate with the bluetooth stack. And when bluetooth is turned of, it tries it again and again. Where when bluetooth is turned on it justs recognizes, that bluetooth is on but no device is paired and doesn't bother any more.
Just an Idea. But it would be interesting to find out if this also happens with an absolutely clean device after hardreset. And if so, if this applys to all ROMs.

I mentioned in another thread, but I installed that new Google Search bar that came out the other day. It sits on your Today Page. Battery life went to heck when it was active. As soon as I disabled it, battery life improved. I'll try turning on BT. You never know.

Just an update.
I've flashed duttys new release (in my sig) and the mA reading is where its supposed to be (between 1-5) WITHOUT having bluetooth running. I'll test with BT on for a little and post back.
EDIT: With BT on I seem to have the same power drain as I would normally.... which is great cuz I usuall leave it on anyway.

This BT phenomena might have something to do with the flashed ROM you guys are using. I've got the standard HTC TyTN2 default ROM and BT on definitely sucks battery power more than without.

Very strange. I could even see it being possible...
With bluetooth on in standby it's doing sub-10mA (5-8mA). With the screen on, it's about 80mA to 100mA.
With bluetooth off in standby it's doing sub-10 again... maybe a little lower.... and with the screen on... still around 80mA.
Doesn't seem to be having the desired effect on my phone (stock O2 ROM), but then I can already get 2 days out of my phone without too many problems.

Now it only saves my battery granted if I'm not using a bluetooth headset. If i'm using bluetooth like via a headset it will drain fast. If I have it on but not using any Bluetooth devices it saves my battery.

Bluetooth on... wtf??
Hi all
... unbelievable, i test this on my device too, and i can confirm -> Bluetooth On (but not using it) saves my battery!!!
Info:
WM6 Pro CE 5.2.1620 (Build 18125.0.4.2)

[Q] [HELP!!]Battery drained in 8h on standby, random restarts and power offs

Hi.
I'm having bit of a problems with my SGS in last couple days; i'll give you last example, but same thing is happening last couple days:
- yesterday I have fully charged my phone; I have disconnected it form charger before I went to sleep.
- today in morning (8h later), phone was turned off
- when I turn it on, I got message to connect it to charger, because battery was on 15% (from 100% to 15% in 8h on standby)
- because this thing was happening last couple days, I have made sure that I didn't leave any apps running in background, that will be able to drain battery that fast.
- I opened settings and take a look at battery statistics;
Cell standby was over 70%!!
When I click on it, it says "Time without signal 70%"
So basically, he has drained almost entire battery by searching for GSM signal. But I have full GSM signal all the time.
But what's the weirdest thing; now that I'm awake, phone will work normally all day; it will last on those 15% almost whole day on standby.
But when i'll go to sleep, ti will start to go crazy over night.
And it's no a problem that he drains almost entire battery over night (it is, but not biggest); problem is that he powers off, so I can miss some important calls in morning (this is my business phone).

do you use a taskkiller? If so, stop using it for a while to see if things improve.

Have you upgraded to Froyo?

I use task manager, and he is "manual" task killer; so I don't have any automatic task killers.

A week ago I made factory reset and clean up my phone, because I had installed bunch of stuff there that I didn't need, and this was faster solution then unistalling one by one app.
I have then rooted my phone (it was rooted also before factory reset), and I have installed voodoo lag fix (before I had one click lag fix).
After that I setup my phone with just stuff I use, and it was working brilliantly till last couple days; only thing that I can remember that I have installed in last couple days was update for angry birds.
One user on Samsung galaxy forum suggested that I switch on flight mode, and than turn it off. Now I will see if this will help; apparently this resets GSM radio.

Voodoo has always been known to kill batteries. I got 8hours on single charge when I was on voodoo. No big deal

Battery too low to power ON!

Hello all,
I just got home from work, and to my surprise my NC wouldn't wake up, and pressing the power button did nothing. This was extra surprising since it was fully charged when I went to bed last night...
After plugging in the AC adaptor I got a message on the screen saying "Battery too low to power ON. Wait 15 minutes and try again". After about 10 minutes it powered on, and the battery widget said 12%.
Any thoughts on what the heck happened?? Up to this point, it's been working pretty much flawlessly, and only losing a few %s of battery each night.
BTW, it's a rooted 1.0.0 version.

My guess is that you had some process that was sucking up the CPU. I had this happen once with a turn by turn Navigator (obviously not your issue). Of course the power down killed the process and it did not happen again until days later.
What were you running last night? Did you install anything new?

A few apps updated but I didn't install anything new. I'll be keeping a closer eye on it tonight and tomorrow, though.

Do you have a task killer installed? They can sometimes result in strange kill/restart scenarios.

Wallswitcher for me twice has had an error switching wallpapers, and when this happens it pops up a dialog informing me and then proceeds to sit there forever with the screen on. However, in this case I see around 4%/hr usage.
Maybe something similar happened, except with heavier CPU, higher backlight, etc.

I was playing around trying to see what still worked of the original B&N stuff after I rooted and I started the app that reads a book to kids. That app did not turn off when I killed the screen. It drained my battery fast. I don't know if this is just on my NC or others, but it's worth looking at. Check Nook Color Tools/Settings/Battery Use.

Are you referring to the Fava Book Reader or something? Mine doesn't die either. I have to manually kill it and yes, it drains my battery.

Battery drains quickly

Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?

There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.

What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.

Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.

Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.

So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set

I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

Absolutely sudden battery drain-GingerDX

Hello Guys, I'm using GingerDX from months and lately I started getting a strange problem- I go to bed with fully charged phone and in the morning the phone is switched off and when I turn it on it has only 1% battery left. This happened only 3 times-always through the night-one of the times I was even on airplane mode. Beside this- the battery acts pretty normal- 2 to 3 days.I took every popular battery saving measure, by the way and the internet traffic is always off when I don't need it.What this could be?

It happen on all roms,that battery goes down very fast. Like 2% in minute. If you see that,just reboot your phone and problem is solved + stop running services!

Thanks, but I can't see that, since it happens while I'm sleeping.I also have very few services running almost all of the time.And why isn't this happening all the time- I'm using the phone in the same conditions and settings all the time?

if its at 1% and the phone continue work then you might need calibration, but if you are telling that its shut down then might be hardware problem( of your battery)...
but you dont loose anything to go back at stock and see if the problem resist....

It shuts down, because the battery got empty at some moment-I guess this is normal.Then it stays switched off till I awake and notice it,let's say few hours ,and then when I am switching it on- I guess it has enough power just to turn it self on, after which I'm putting in on the charger.And yes- battery is calibrated last time I changed the Rom.
