Battery Drains TOO FAST

Not sure if im the only one experiencing this issue but i think that the battery dies entirely too quickly!!! Being that i have a launch day batch i'm not sure that everyone is experiencing this issue! IT seems like the LESS i use the phone the faster it dies, i know totally contradictory but thats what it seems like any ideas, known tweeks. Let me know

There are a few ways to fix this. Most can be found through a quick search. Trying a task killer, adjusting settings and rooting/flashing a new ROM are some ways to fix that issue.

Nope haven't had this issue, had mine since launch. If its really an issue for you, buy a new battery and if that doesnt work there are other fixes around this forum that you can try

turn off background data
adjust settings so that things aren't syncing as often
turn backlight from 'auto brightness' to a low setting
turn wifi sleep setting to 'never'
turn off bluetooth, location settings also
i had mine off the charger for 16 hours still had over 80%

I hate you, I want your battery.
I think there really are bad batteries out there.

well, tbh, most of it was in standby. short phone call, some texts, that's about it. it wasn't as if i was putting the phone through the ringer

See if there is a difference between weekdays and weekends.
I do have the same short battery life and my battery will die around 6pm on weekdays if I don't charge it during the day.
However, my evo was able to last all day this last weekend.
The only reason I can think of is that I have weak reception where I work and the phone is probably using full power to keep that connection. Hence the massive battery drain.

If your signal is bad, your battery will die very fast. I work in a giant metal box of a store with a constant 1 bar. My battery drains like crazy. If I disable mobile network it increases ALOT.

Make sure you have the updated radio and there are plenty of battery fixing threads. Custom rom will help a lot as will removing the bloat.

I can cosign on this issue. Last night I had the phone on the charger. I unplugged it because it was fully charged and I don't like keeping my things plugged in all night. I wake up this morning and reach for my phone and it's practially like 25% battery life. It was on standby and I didn't set up Friendstream, Auto Syning, etc. I have everything on my phone set to manual.

interesting thing i just noticed on my battery; i just fully charged to 100% (using battery indicator); i left it on the charge for another 5-10 minutes, then unplugged it
literally couple of minutes later, battery shows 95%; not sure why it's doing that since i don't have any apps running in the background and my signal is fine; after it got to 95%, it seems to start draining normally
this is the 1st time i noticed it; the previous time, it drained normally (100 > 99 > 98 >etc.)

You know why its hard to nail this down?
Its because people say
"i took my phone off the charger and in 4 hours of stand by its now at x%"and that's pretty much it.
Some facts:
Without knowing your db we don't know what kind of signal you have.
All task managers are NOT created equally. Just because the free one you got says there isn't anything running doesn't mean that its not still on in the background. If you are running sub 175mb in free ram then you have stuff running that doesn't need to be. Find a different task manager
If you root the device and download one if the many custom ROMS. Remove all the stuff you do not use. Your baster life will go through the rood. Gsd and other crap that does nothing are huge battery hogs.
If you can't be bothered into doing the above then you aren't going to find any answers. Either but an extra charger or return it. You can fix it but its going to taker you doing something.

As i am a tech for sprint, i know about all this and i have all those settings off, wifi, mobile network, Brightness down, bluetooth is always off. And to no avail!!! I must have a bad battery! Seems like store demo i use to show customers last longer, HAHA. Even though if i still see an issue i will just swap a battery out of new one( PERK OF THE JOB)

See this is what I'm Talking about, I'll take my phone of the charger in the morning and by the time i get to work 15 minutes later! My phone is like at 70% Without me even touching it, Waking it up. Recieving texts or anything. The roads that lead to my work are well serviced areas of sprint reception so i know my phone isn't looking for signal. This is a major drag!

My DB is always low(closer to -0 the better) so i know that is not the issue.... next!

With good db that isn't normal drain. Return it for a new one.

Free Swap Here i come

Selling Sprint phones at Radio Shack doesn't make you a tech... I worked at a company called WDS Global a couple years ago. THEY are techs. As a matter of fact, WDS Global handled all the tech support for the EVO on launch day. They even had a rep in my local store.

Use damagecontrol the ROM in the evo development section of this forum it increases battery life because the dev tweaked internal system it worked wonders for me give that a shot.

Loving the 1500 Battery

Could too enlighten me further what exactly is the 1500 battery?
Pooped from my Samsung Vibrant using XDA app...
Dont mind the skidmarks...

^ the stock battery is 1500...

Indeed I've gone overnight without a charge and heavy usage the next day and still wasn't 1/2 way depleted. I think the Super AMOLED has a lot to do with the awesome battery life.

"HEAVY usage" is relevant. I've had my Vibrant for 3 days and the battery is unimpressive to say the least. Hopefully, it will improve.

I am not sure what you have to do to prolong the battery life besides not doing anyhting, i.e. I was in the woods this weekend with no service at all, kept the phone in flight mode, used it to snap 3 pictures and 3 vids no more than 1 min each - the result is impressive - unplugged the phone at 7:30AM and by 4PM I had 70% left. Woohoo, I guess, the phone did nothing for 8.5 hours and only drained 30%.

I unplug my phone everyday around 6am and as of now, which is 7hours later I'm sitting at 92%.
What have I done on it as of today? 4 phone calls, 3 emails, took some photos.
Things I don't do all day.
Watch avatar over and over, let it idle on 3G for no reason, let it idle on wifi for no reason, turn off auto brightness.
I do have a regular schedule of charging.
I plug it in around 11pm turned off
I turn on my phone around 540am and leave it on the charger. I'm always greeted with the Its full unplug message around 6am.

how come your display use is only 8 percent mine is like 74 percent even tho i have it set on the lowest possible......

Thats saying out of all that time his phone has been on, his screen has been on 8% of the time.
If you use your screen a lot the number will be higher and I'm sure the more battery that would be used.

Great results so long as you don't need any network access for email accounts to work. That's not really an option for a lot of people. I have to have either 3G or WiFi on at all times to receive emails. SMS messages will come in over GSM so if that is what you do rather than email than you can turn off WiFi and 3G and still do texting.

Email works just fine over 2G (EDGE). I've found that setting it to 2G-only while keeping WiFi enabled (setting to stay on during standby) if in one location for a long time works better than keeping 3G enabled.

What is your build date? Find manufacturer date on box or inside phone.

I get good battery life... only gone down 1% since I unplugged it from being fully charged in 30 minutes with the display usage at 84% with GPS on.

yeah, tomorrow, i'll try to leave wifi and 3g on all day and come back with the result.

Checked my standby draining today. Lost 10% in 7 hours and 10 min. Look good, no ?
This is with: Google account sync calendar and contacts, push exchange email, 3g, auto sync
Must add that Tasker is also running and set to check everything to 30 min intervals

I have owned this phone since day one and am convinced that wifi is the biggest battery killer for me. I unplug it at 730am in the morning listen to live stream podcasts on the way to work and back (35 min commute). Make a few calls and texts, check all my normal websites on my breaks and when I get home at 630, I still have about 60%. In the settings I leave gps off and wifi on so when I get home its automatically on. By 930 the phone is at 15% so I am convinced its the wifi.
Having a screen this nice is worth the mediocre battery life, its actually better than my g1's battery life, so I am happy.

I'm not sure, I think it means of all the battery that has been used, 8% of it went to the screen. I would also like to know how you got that fantastic number! I usually have my brightness on minimum since I mostly use it indoors, and the screen is by far the largest consumer of battery power, even on days where I mostly listened to music (local, not net streaming) with the screen off...

I'm definitely getting better battery life out of this than my previous smart phones. Currently at 55% 1d20h unplugged. Light use, but still.

Battery drain help

My battery on my dell streak drains very fast. For example i had it plugged in until 100% in the morning. Then about an 1 hour and a half laater without using it that much it draimed to 67 %. The battery usage says cell standby 49% and the screen was 17% and those were the highest. From my nexus one i kno that cell standhy should not be that high. What is causing this to be so high? And why is my battery draining so fast?

Are you on1.6 or 2.1? mind was the same on1.6. Loads better on2.1. But I have also noticed that if you are in an area where 3g is poor it spend slot of energy trying to connect. I turn of data quite allot and it doubles battery life. BeforeI was getting less than a day now I get a day easily...... UnlessI have a load of widgets
Sent from my Dell Streak using XDA App

Im using 1.6, then 3g then probably is the problem. Did u do anything to fix this problem?
Sent from my Nexus One using XDA App

I had similar problem and deleted my task manager, as amazingly it was using more battery than running applications
It also stopped 'fancy 'widget from updating, even when told to ignore it
'Appbrain' market was also another major problem, i also think that 'smooth calendar' doesn't help; but i'm still experimenting.

thanks for reply, im using advanced task killer, maybe i ll try taking it off to see if it affects the battery in anyway

If you look in the battery tab you should see where your biggest power hogs are.
Mine happened to be media.
I had removed all the media from my SD card, forced redection etc and it still drained the battery.
Eventually, I removed all ringtones and music from the SD card and did a hard reset, ran it for a full day monitoring the battery usage. Now I'm adding a bit of music back to see if it was a bad media file that caused the indexer to draw power.

For me the battery usage is almost 60% cell standby...then every other small thing piles in. Why is the cell standby so high. I would think that the display would be the highest

I'm having the same problem on my streak that is running 2.1 in the USA.

Delete ALL your apps
Weatherbug also drinks batteries, but it's so good this time the good outways the bad

I havent purchased my streak yet, does anyone know if 2.1/2.2 will have better battery consumption on this device?
you guys are scaring me..lol

Nobody can say for sure what the upgrade with have until it's released.

My experience is thus......
Widgets drain battery
T ask managers drain the battery, I now use watch dog
The biggest one by far.... The data connection drains battery. Especially if its a poor connection.
So first thing is to turn of 3g etc when not required. I get a day easily. If I add widgets I get a day just. This is with location gps and sync turned on all the time

I was haviing normal smartphone battery life, about a day, then started having some trouble so I uninstalled some apps. But, I also let the battery die completely overnight then charged it full and am now on day three at 55%

Day 3 at 55%? Do you have a SIM card in your phone? Data enabled? 3 days and only 45% battery life drain is unreal. I have a fresh restore and my Streak barely makes it through the day still, no widgets installed, no network-activity causing apps running in the back, no task managers. The battery life on this phone sucks.

3G has been on the whole time as well as wireless networking and gps. Bluetooth was turned off until about noon today. For widgets I've got Weatherbug Elite, Jorte Calendar, 3G Watchdog, System Info and Latitude. The phone has had pretty light use for the last few days because I was doing some work around the house, but I did use it for the occassional game of solitaire and as my ebook reader at night as well as a few short calls.
Today, on the other hand, I've made several phone calls (more than a dozen, some longer some short), have had bluetooth on half the day, wireless enabled and a small amount of surfing. I went from 55% at 8AM to 19% at 9PM.
I think the battery meter was in need of proper calibration and that's why I did a full discharge and recharge. I'm as shocked by what's happened as anyone else.
Oh, I've also had Juice Defender installed both before and after the full discharge/recharge. Before I did that I wasn't even getting 12 hours out of the battery and that's why I tried it.

Dolphin browser HD, no sh%t, my battery went from approx 95% to 3% overnight. 9 hours

My battery life has been pretty good for me, when I go to bed it's at 100%, come morning after 2 alarms it's usually at 97%. I usually have 3G & Bluetooth on. Then throught the day I don't use the phone much besides the odd text and odd e-mail, with a couple games of Robo Defence, and come 9 in the evening I'm usually around 40% which is pretty good considering that I get crap signal at work (very weak signal with the occasional signal drop) and I know that usually uses a lot of battery.
However, the other night, I went to bed with 100% on the phone and some time between then and 6 hours of sleep, the phone had died completely. Couldn't turn it back cos there was absolutely no charge in it...need to charge it a bit before turning it on. Quite worrying as I use the phone as an alarm during work days (luckly it was the weekend) and I don't acutally know what caused the massive drain

Thought I'd share my experiences here with you guys....
I've had my Streak about 4 weeks now, it's a US Beta version, on TMO US so no 3G, only EDGE. The only widget that uses data is Weather & Toggle. I have had sync and Facebook sync turned off, and only use GPS sparingly.
I tried everything - I started turning off the data connection (3G/EDGE in the top right menu) and basically uninstalled every program I thought could be using battery. Still, it would go from 100% at bedtime to around 60% in the morning. I then tried Airplane mode. Still was draining! I then installed Juice Defender, and it actually went from 100% to 0 - it died that night! D'OH! The whole time is was a 50/50 mix between "cell standby" and "phone idle". It doesn't show any programs using battery. I also tried Drain-o-meter, but it didn't show anything else either.
Well here's what finally fixed it for me -- turn back ON the EDGE/3G data connection and leave it on!!!
I'm guessing there are things running in the background (my guess is Weather Toggle widgets but the drain was still there even after I uninstalled it), possibly system processes, that require a data connection. In my case, that fixed it... now it goes down from 100% to about 92-95% overnight. Now I just leave the data connection on and it's all good!
I'm not saying this will work for everyone else, but hopefully maybe there's at least 1 other Streak user who has the same problem.

I was not happy with my streak's batteryperformance either (stock ROM), until a recent discovery.. It seems the Mail client (not gmail or touchdown) caused a partial wakelock if I had set it to 15min intervals (have 2 accounts) Draining approx 10% every hour.
After I set it to sync every hour, I dramatically increased the battery time.
Today when I checked it I had only used 3% in 5 hours (normally it would be minimum 30% in the same time)
I suggest you check your settings if you have the Mail client set up with accounts.
This changed my perspective on batteryperformance TOTALLY!

Bad battery life after 107 update

Just like the title says. I have checked all my settins syncs which programs are running in the background and so forth.. so im sure its not that..
Anyways here goes.
Before the update I could get about 12-14 hrs of use out of a full battery charge, however after this update I can only get about 5-7 hrs out of a charge.. Nothing had changed.. my usage is the same, my wifi,bluetooth,gps,4g are all off. I don't have any programs syncing or updating in the background.. So i have NO CLUE as to why my battery life cut in half after this update.

I already posted this elsewhere......my battery life was really great before this update.
Same exact settings now as before, plus the phone was reloaded to factory settings by the Sprint store first as I was having some other issues...email not coming through timely, cell signal falling and dropping calls, etc.
My battery life is now 1/2 of what it was prior to the D107 update.

I would say wait and see. When I would flash roms on my HTC phone the battery would die quickly for awhile. After 2-3 full charges it would go back to normal.

Check Cell Standby in battery status. See if Time without signal is 50% or more.

Cell standby is 18% and time without signal is 7%

My time without signal is only 2% So I'm not sure what is going on to make my battery life soo bad.

i got 9 hours today with decent usage where before if say 12 or so ... since the update my time without signal is in the 30-50% range on average & it was 3-4% before .. im a little frustrated on that & i know its taxin the battery a little so . . .

my update has really screwed my battery life. I notice too that Juice Defender keeps reading at 1.00x instead of 1.6-1.8 before the update. I also notice my TWS was at 50-52%. I tried the Airplane mode toggle and it didn't do ****. I really love this phone, but i'm about to return it and try another before my 30 days is up.
So far, i'm concerned with:
back button is not consistent (works sometimes sometimes it sucks)
TWS over 50% of battery consumption.
upgrade made juicedefender not work
little wobble in the phone but not too bad
scratched screen just from rivet in jeans
AND pissed about the tv out that sprint omitted

The back button is a defect in an early batch of phones.. If you swap it, you will probably get a working model..
My email app didn't sync after the update, so I had to reinstall Roadsync. It might be the same thing with JuiceDefender.

My battery is getting much better. Not sure if it is the galaxy rom, the update or my battery is just getting conditioned better. I unplugged my phone this morning and have been on it constantly web browsing, music, 4g, 3g, lots of tapatalk use. 36% left and just approaching 4hrs of being unplugged.

How do you roll back this update.
Sent from my Samsung Epic 4g using XDA App

after i re-flashed and updated, ive experienced big drops from the 90% zone to like 75% in a short amount of time but then the decrease stays pretty slow.
im using adv task killer on maximum and juice defender
this combo works pretty well for me, i cant explain the 25% loss. I think my battery still needs calibration, but i get around 14-18 hours normally.

I've noticed the increased battery drain also. I've been tracking it the past couple days with Spare Parts. If you open Spare Parts, click on Battery history. If your phone is running like mine is right now, the Running time is at almost 100%. That means that something is preventing it from sleeping. Next, click the tab that says "other usage", and change it to "Partial wake usage". Mine is showing that Android System is the culprit, causing the partial wake lock. It was not doing this before the DI07 update. I did a factory reset this morning and the only app I installed was Spare Parts, just to make sure it wasn't an app I was using. I get the same results on a fresh clean ROM as I do using noobnl's ROM. NOT COOL!

Well my full run through of the battery is over. I've turned a new leaf about the battery on this. I'm keeping the Epic.
Conditions: Was at zero brightness for about 4hrs of this. Set it to 0 after getting to work. You can see the screen perfectly fine at 0 indoors. (30 minute ride)
GPS - Off except the couple times I checked out google earth
Sync - full manual syncing / with background data on to use the market
Usage: Heavy heavy usage for all but 20 minutes. Total time with screen actually on was about 4 1/2 hours. Lots of tapatalk use, streamed about 20 minutes of CNN via Slingplayer, Streamed about 10 minutes worth of music via last FM. Dolphin browser usage. About an hour of total usage was over 4G
No task managers (well Androids but that doesn't count), no juice defender.

After all that it has been sitting at 3% for 20 minutes (after taking the ss) with no usage as I wait for it to finally die and write this post. Just over 5hrs straight of near pure 3g/4g data usage over various applications and multimedia is perfectly acceptable to me. This is WAY longer than the average consumer laptop would get under similar usage w/ an aircard.
If I didn't use the phone like a miniature laptop so heavily and just kept it to normal use and some phone calls with auto brightness on I'd guesstimate I'd easily get 10 hours or so if not a lot longer out of it.

the reason your getting bad battery life is because it reset all your battery stats. it's going to take a couple days til your battery life gets better. try the bump charging method.

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)

I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.

Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though

If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.

Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%

Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time

A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.

Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.

An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.

I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.
