Display Killing Battery

For some reason my battery has been dying unusualy fast since about a week ago. On the battery usagepage it says display is using up 90-97 percent. It never did that before..it would at most be at around 50.
I'm on a dk28 rom. At first I was getting amazng battery life 20+ hours of heavy use but now I'm barely getting 5. I tried odining (can I make it a verb) back to stock and then going back but it didn't help. Anybody else experiencing this?

There been a lot of talk about worse battery life on froyo leak. Make sure you are still stopping the drm media hub crap. I'm on froyo and my battery is slightly worse. Keep your screen display all the way down too.

Is there any resolution to this? I'm experiencing the same problem, display draining the battery...was thinking of going back to di17, clearing and going back to dk28 but that didn't help you, hmm is there a certain way about fixing this?

Battery, wow!

With light use im now at 28 percent going on 38 hours since last plugged in. anyone else noticing way better battery performance?

38hrs huh? 3500mah battery and left completely idle I assume. No way in hell you got that on stock battery.

The only way you could have that on a stock battery is have the phone off and battery pulled out for 34 hours.

I'm getting a lot better life with the overclocked kernal and midnight eb13. 8hrs of moderate usage and was only down to 55%. I'm loving it.

I am running through the stock battery AND the 3500mah battery each day on EB13. I dont know if its my usage has changed or what, but EB13 is a battery hog. Lost 25% from my 3500mah battery overnight as I was sleeping. LOL.

keep an eye on your TWS. This has been a huge issue for me, and keeps draining the life out of the battery. Only solution so far seems to be the ariplane mode toggle work around.

I was able to make 30+ hours on a single full charge with dk28.
I still haven't put eb13 through its paces but from what I'm seeing, its great with battery.

suggestions!!!!
if you all want better battery life then disable your data network ...the way to do this is hold down the power button ...just like you are turning your phone off, you will see the data network. hit that button..it will disable your internet constantly running in the back ground and also will disable notifications...you can turn it on at your discression when you want to check your email, internet, or anything pertaining to data network...but trust me this will give you alot more battery life..also you can install setcpu and clock it to run lower when your phone is charging, not in use , or even when you are using your phone...this also helps substantually...good luck guys

Very nice suggestions I'd also like to add that using Wifi will use a LOT less battery then 3G probably 80% of the time. At work I have poor reception so leaving 3G on will kill my battery, however WiFi it's not uncommon I leave work after 10 hours unplugged with only 20-25% of the battery used! Make sure to set the wifi sleep policy to never if you go this route, that way it never goes back to 3G even when sleeping.
Turning data off completely and using the phone only lightly all day at work (a few text messages) (10 hours unplugged) i've left work with 88% percent battery remaining

Battery life has improved greatly. I turn off background data, stop the Omadrmblablabla service, no live backgrounds, but it is full color. With moderate use I can see 10 hours and still have 40% before I go to bed.

My battery life has been greatly increased too. The battery indicator seems much more accurate too. I did the factory reset several times, then wiped and used the samsung installer.

I wish I could be as lucky as you. This is by far my biggest complaint with eb13. I have tried flashing multiple times to no avail. How did you update? odin, samsung exe, update zip, or ota?

I did an odin flash, and my battery is much better as well. On 2.1 stock I would usually get about 16 hrs with my usage. Now, with the same usage on EB13, I can get about 36hrs (charging every other night).
I did the zip update first, and my battery was awful and only lasted for 4 hours. But since the odin flash, everything is great!

Samsung exe. Did you update your profile and PRL? I had TWS issues until I did that. After updating the PRL I have been golden.

PRL fix will only last til you reboot I think. Have you rebooted since PRL udate?

What's the tws bug that drains the battery? Airplane toogle does what?
But as for myself, I'm getting way better battery on eb13. I think some people have bad experiences sure to installing done apps rgat may run in the back ground. Do this test, reflash stock. Don't install any apps but what thee phone comes with. And use the phone for 2 days. Then you will notice rgat index outer does last longer.

I have tried that as well, no dice. Only the airplane toggle seems to fix it. I have to airplane toggle every time I boot up. Once I do that the TWS is around 2-5% which is normal for me.

TWS = time without signal. Airplane mode resets the radio on the device and somehow fixes it (albeit, temporarily). I read somewhere on here people believe it has something to do with the fact that, for some reason, the phone is looking for a gsm signal as well as cdma, and since this is not a gsm phone, it obviously can't find a gsm signal. The constant searching for gsm is causing a drain on the battery. This happens in areas with full sprint coverage, like my house. For whatever reason re-setting the radio forces it to stay on cdma mode only. I think i read someone saying something along the lines of it being a problem because this is was an update created for devices across the board, ie, for both cdma and gsm handsets. Its just a bug that needs addressed. Some people have it, some don't -- which is even more frustrating!
If you are not experiencing this problem, please tell me what method you used to update. I have only tried Odin (and update zip once), so I will try the samsung exe to see if it does anything.

Bionix - Best battery life ever!

;D I'm running Bionix v1.3.1 and the battery life is AWESOME. Yesterday, I did a LOT of texting, gaming and talking. By the end of the day, I still had 90%.
Usually, if I do that on any other ROM, by the end of the day, I'd probably have around 0%-30%
I didn't recondition the battery, either.
BUT ONE THING, I've NEVER EVER experienced a problem with the GPS on my vibrant, but right after flashing V1.3.1, it wouldn't work anymore. It'd take like 15 mins to lock D:<

wow. using any different kernels? What modem? I get stock battery life on bionix. I have no idea how people are getting such amazing battery life. Maybe i need to do a battery reconditioning.

That's amazing I used it and I ended the day with like 40% i used trigger and I get like. 70% 60% on average

Same here, running 1.3.1 with the overstock kernel, keeping wifi on all day due to the great wifi sleep policy, after an 8 hour work day of moderate to heavy use my battery is at about 70% everyday. I don't even want to update to the newest version of overstock, too scared to lose what I have.
Edit: And my gps works flawlessly, but I've done the hardware fix on it.

Hows that paperweight? Im got good battery life with bionix, usually under 20% after work(8-6). Im getting great battery life with trigger rom now. Usually around 40% after work. All this is with music playback for atleast 4-5 hrs a day with data running.
Hate calling people liars but I will never understand people who get 2 days wiht an oem battery. I jsut dont see someone besides an extremely light user getting 2+ days without a charge. I got 2 days with my 2700mah extended battery.

can you play angry birds for 2 hours and say how's your battery?

I also swore by bionix since it's first release but seriously trigger + overstock = fastest rom with the best battery life I've had so far

If you get more than a day on your vibrant...
You need to start using your phone and not just checking time or battery every 10 minutes.

This is probably as accurate as you can get:
Heavy use: 6 hours or less, MAYBE 7, but unlikely if its heavy use.
Moderate use: 10-14 or less, no more than 14.
Light: a day, and possibly more.

It was good for me but no as good as Trigger,but the rom that lasted more on a charge for me was Azura,it had incredible battery life.

I used to get 2+days battery life on mine when I was running previous version of Bionix. I can't recall which version it was, i think 1.2.0. It was when the froyo was released for the vibrant i believe january-febuary-ish. After flashing to 1.3.1, i can't get passed to 24hours anymore. Also all my settings, syncs, wallpaper (etc..),except the modem,kernel, and 2 scrabble apps, where similar. The KB1 modem was one of the culprits of the drain and i have it replace with the JK and KA variants (still testing which one is the best). KB1 was awesome with my gps locks though with almost 3 meter accuracy with 8/12 sats locked). The speeds were also like +1-2mbs depending on the location and this was tested with a friend that has JKx modem. Also google googles and the 3d gallery up was not shutting down the sensor server which was draining the battery hardcore. Until now I still havent been able to replicate how I got the 2days battery life. I could revert to the previous bionix version because i have a back up too but this battery issue is not really that of a problem.

Finally sent EE03 packing

I've been running EE03 since it was leaked.
The reason I stuck with it was because I saw EXCELLENT battery life (compared to SRF1.0.2. which I was running previusly) with the same usage (for me)..
Gingerbread was laggy at times, had some minute bugs that were tolerable (during my usage patterns) but I fell in love with the battery life.
On SRF 1.0.2 I would put my phone in airplane mode overnight to keep the battery from dying while i slept.. while it was a workaround (for me) it wasn't the most desirable solution.. I felt adventurous one night while on GB and left the phone sitting, no airplane mode, just to see how far the battery would drop compared to SRF... i only lost 5% overnight.. THAT was the ticket for me.. so i kept it and ran it.. haven't flashed a thing since.. no new apps, no new configurations.. it was working beautifully (as well as a leaked build could be expected to ) .. but it was very tolerable for me..
Until the last couple days... I noticed (all of a sudden) that while I'm sitting next to my computer, phone plugged in to charge before bed, the phone would disconnect/reconnect to the computer.. it would make that sound when you plug it in.. it would do this no matter what percent of charge it had.. for no rhyme or reason... I wiggled the cord in both the phone and computer in case the cord was to blame.. nothing.. i couldn't 'force replicate' this anomaly.. Further, at night around 4 in the morning the phone would vibrate and pop up that it was going to die, please plug in charger... the second night, I put the phone in airplane mode overnight and I STILL got the pop up at 3am that it was going to die...
So I decided (at 11:30) last night to ODIN back to EC05, then root w/ CWM 3.0.2.5. and flash SRF 1.1.1 .... I'll see how it goes.. hopefully battery life on this build is better than what I experienced on 1.0.2 lol...
Sorry for the long post.. I just wanted to share my frustration and see if anyone else had this weird anomaly w/ EE03.
/venting and pissing off the rest of XDA for long post

ive had the same problems with the disconnect/reconnect sound off. on top of what you have mentioned i have also had the problem of the phone being fully charged but showing the red charge light instead of the blue fully charged light. additionally the phone seems to get much more hot on this rom, i can simply be playing a game or something and the phone will get so hot that the charging is forced to be stopped, never had this problem untill the ee03,

I had the same issues , I was worried my phones charging port might be damaged but a quick flash back to srf proved it was the EE03 rom
Besides that, everything ran perfectly for me.

I've had problems with the phone not charging all the way. It will show 100% charge and then stop charging. When you unplug, it then shows the actual battery level, which has been as low as 35%. I've tried lots of things like wiping battery stats, but it keeps happening randomly.
EE03 is still fairly buggy. Some days my battery life is fantastic. Other days, it drains like a sieve. Even when I have fairly similar issues. Seems to correspond to how "hot" the phone is running that day. Also, phone calls just eat battery life.

going back to EC05 too... gonna be a long few weeks (hopefully only that). Awesome, just too hot, buggy, and I get PISSPOOR battery life.... but I have horrible reception at home, and even using roam control it still sucks down the juice. Also, I cant remember, is the settings process supposed to be permanenty running??? mine is, maybe that explains the settings not sticking... go samsprint go!

Its going to be hard for me to leave EC05. Full bars on my 4G. Wifi Tether is insanely fast and reliable. Bluetooth pairs properly. This has been the best modem for me by a mile

Yeah, the most I was able to get out of EE03 was 8 hours of idle time with the battery calibrated.

initially, I was getting stellar battery life, but the last couple days of using it, I noticed my phone getting hot. I have no idea why things were slick as snot for a long time, then it all went to hell in a handbasket.. good thing is it's easy enough to change to something else LOL (thanks Epic Devs )

EE03 has been strange for me at times. I've noticed when it's charging and it makes the charging sound, the battery life will be terrible the next time I take it off. However, if I just reboot it, it usually stops making the sound at random times, and the battery life is giving me 12+ hours/day.

GingerBattery Sucks?

I dunno man, just gingerbread itself appears to have fubared my phone. I wiped sd, wiped phone, factory reset, odined stock EC05 and took the forced EI22 update. Even still, android system chews through battery at >90%. A small thermonuclear power plant could not give my phone enough juice.
This coming after I tried multiple combinations of roms, kernels, uninstalling apps, and freezing data sucking apps that caused high wake locks....
I have tried stock gingerBreadEI22, ACS 3.5 - 5.5, ERA RC1 & 2, and Random Rom, with nubernel, different samurai kernels, and just whatever the chef cooked up. All the same, excessively high "system" battery usage.
Anyone is / was having the same issues and able to iron it out?

That reading for system is the norm. I get 24 hours with like 80%
Sent from my SPH-D700 using XDA App

I agree with Alkah0liK, but with my experience so far, if I don't use the phone all day it doesn't really use the battery, but as soon as I start talking, listen to music, or web surf it because a pig. I actually want to go back to 2.2 and use frozen rom again from ACS again. Can't figure out how yet though

Ok thanks, I was wondering what others were seeing.
I must be doing something it does not like. I can go a couple minutes with the screen on (at lowest setting mind you) and watch the battery drop 2-3% or more, almost dead battery within 10 - 12 hours even in /out of airplane mode...
Is there something really wonky with CWM? Funny thing is this started happening right about the time i switched over to v5. I am in the process of reverting back to wiping everything, odin to EC05, and going v3.1.01 again.

The battery life is better with gingerbread, but its not going to make your phone run 2-3 days on one battery life. Sorry my friend, those days are long gone. It would be very hard to find any cell phone that can run for longer than 24 hours these days.

No I get that, but I was able to use my phone for more than a couple hours a day before gingerbread. B4 the leaks I was running Viper Rom EXT4 with genocide at 1200 ondemand and still getting through the day. If I cut it back to 1000 and went easy I was only charging overnight to bump it back up to full.
I was even using RandomKing's and ERA's leak based roms with EH06 & EH17 without any issue. For me it really has been either the EI22 / CWM5 / latest roms.

Hey alky, I was also in your position. I tried every rom you tried, with minimal pleasing. My advice, if you can live without 4g, flash the current cyanogen and set the render effect on night mode. Enjoy a thorough battery life my friend. Nothing beats it thus far. Can't wait till we see cm9.

Thanks! That was actually going to be my next try. I only get 4G when I am downtown, not very much as of late anyway.
FYI- I have found what I suspect as two possible culprits on ACS 5.1 & 5.5, and ERA RC1 & 2. According to better battery stats CM_VnoteService and *Sync for GTalk will run and run and run unless you open the applications and go through initial setup. Those two process will stay stopped so long as I leave them open / connected, once I close them - the partial wakelocks restart and run until you open the apps again (or just uninstall).
Even with my obsessively high amount of .acore launcher time and better batter stats application usage, they are still well below the "system" usage under the process dropdown.

It definately sips battery when not in use. Although I feel I get more screen on time with ACS ICS. I regularly have over 3 hours of screen on time with GB, I don't remember getting 3 hours on even SRF 1.2.

Turn off your syncs. If there is no signal your syncs will keep trying and burn up your battery. Turning off data mode in low to no signal areas will conserve battery.

Make sure upgrading to GB did not change any syncs. Also make sure new apps aren't loading into memory and sucking battery like Talk or Google +. Grab Memory Booster lite and pull up the task killer to see everything loading on your phone. The stock task killer sucks.

I recommend paying the $50 for battery and portable charger/storage unit. I'm a stock user who just had 41 hours with my new battery with 2hrs of screen time. I really like having two batteries too. No more charging cords connected to the phone...ever
Edit: the batt. I bought was a stock 1500mah batt. and charger kit from a sprint store. No regrets

Also, be sure to go to settings on your facebook if you have one and turn off notifications. That helped my battery life as well.

Still running 100% ERA Legendary v4.0.1 (with provided kernel) and I squeezed ~74 hours of pure standby time out of my stock battery.
Data Sync (FB every 6hrs, Weather every 2hrs, Google push)/GPS/Auto Brightness = on
TWS = 4%
Display Time = ~24mins (sent 3 texts and checked 1 voicemail)
100% on 3G
Had I turned off all synching, GPS and lowered brightness all the way, I would have probably gotten 4 days.

Battery life has heavily depended on the strength of signal for me as well. I moved recently and have been living in the basement while the renovations are going on upstairs. No airave (it is used at a different location) means little to no signal in a brick house due to Sprint's POS signal frequency. Although I've been flashing different kernels and maybe not allowing them to settle + undervoling a bit (very conservatively, will not OC over 1100). But it is true that since days I was on BB Tour, not one phone lasted a full day without an extended battery. I'm pretty much decided on VZW switch once Prime comes out - one of the factors is better expected power management of ICS and possibility of adding an extended battery without worrying about making the phone too bulky (given how thin it is).

Man that sucks, I've always had great battery with gingerbread. Right now I'm on RC2
