What sucks YOUR battery?

I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).

Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.

The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.

Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.

Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.

my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.

My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
Sent from my SPH-D700

So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.

First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

3-4 hours of talk time takes up 70% of my use during a 10-16 hour usage. Second would be my screen.

My screen is 79% and cell standby only 7%
My screen is all the way down, even tho with the new update I notice my screen got dimmer than before.

ARGH! I just can't take the lack of a notification LED!

It's finally driven me to the point that I'm just going to sell the Nexus for a profit and get a G2. I can't take picking up my phone every single time I want to check if I have a message. I've never had a smartphone without this feature, and it's just a nightmare.

I do miss having an LED indicator too... but I wonder if they took it out due to battery life reasons. Is there an app that can help give better indications in case for missed calls or texts that can do a reminder without an LED indicator... maybe even use the LED light on the back of the camera is better than nothing

i would say just wait until someone makes it so it uses the LEDs under the softkeys as notification lights

Use NoLED, works great for me. I like it more than the trackball notifications on my N1 now, they look awesome on the screen.

I don't want to power-on the screen for a notification that may be left un-noticed for an hour.

I didn't really like the idea of NoLED either but I just decided to try it for the hell of it. I use the blink mode and set the time out to 1 hour so if it's idle for an hour the notifications will stop. I've checked the battery drain and it seems to be quite small with blink mode at least (since I'm only having it display the notifications for 1 second every 30 seconds). So really, 2 seconds of screen time every minute, which is about 120 seconds every hour, or about 2 minutes of screen time where it's mostly black and a few lit pixels, and then after that 1 hour it stops.

I tried noled but must confess I never spent any time setting it up so the battery drain I noticed may have been avoidable.
Just to pick up on the above... I'd want the notifications instantly obvious so that a quick glance at my phone would notify me of any messages. Using the above method I'd only see a notification for some of the time and not all.
Lighting up the bottom buttons would be a much better option for me but in the meantime I might try noled again.

Other than the fact that they're not colored, seems a bit better IMO, more noticeable. Also, battery drain really is minimal with NoLed...

The three pixels on the screen drawing power aren't going to impact your battery life heavily.

to be honest id be more paranoid about burn in , cuz really if i get a text when im sleeping and it goes unnoticed for 8 hours then what

With NoLED you can set notification timeouts, I have mine set to 30 minutes because I always have my phone near me and 30 minutes is plenty. I also have it set to use the Proximity sensor so that if the phone is in my pocket it's not displaying any notification, only when you remove the phone from your pocket and the proximity sensor detects that it's clear will it display the notification instantly. You can also set a "sleep" time for notifications, so I have mine turn off at 2am and turn back on at 6am.
If there is any increased battery drain I haven't noticed it, but then again I don't leave notifications on flashing for hours either.

The notifications move around the screen to prevent any pixel burn-in. You can set them to timeout after a certain amount of time also.
Have you guys even bothered trying out NoLED? Haha

Good to know but on top of that don't the notifications move around the screen?
Edit: ikon beat me to it.

NO!, i fear change!

Have the phone make a sound/vibrate. No need to pick it up.
or download noLED. Problem solved.

I've made a couple posts in the Poor Battery Life on NS? thread( such as http://forum.xda-developers.com/showpost.php?p=10143276&postcount=159) detailing my experience with the Nexus S's battery.
I use noLED as my notification system with large icons rather than the default little dots and no time out method. The only other special thing I've done to it is turn on the proximity sensor so noLED doesn't run while it's in my pocket. My boss likes to do a lot of paperwork in the super late evening/early morning and sends me emails accordingly(this is why I don't leave the sound/vibrate on, lol). noLED's impact on battery life is extremely negligible. I would put it on par with the power with the power consumption of an actual LED notification light due to the way SAMOLED and blacks work.
And, if you're worried about burn in, like someone said, the icons shift around the screen in order to avoid that.

that proximity sensor idea while its in your pocket, genius

Just tried noled again and am noticing a few force close errors.
What settings are best for this app and when a notification is received, what are you using to wake tje phone again as the power button causes issues as explained in the splash screen after install?
I'm also seeing all the bottom buttons light up as well as the notification on the screen, is this normal and if so is this not consuming battery unnecesarily?
Seems a tad buggy to me this app on the Nexus S. Would appreciate exact settings / configuration from anyone that has it running satisfactorily.

Battery Obsession

What is wrong with almost everyone's obsession regarding battery life??
Oh my gosh I'm so tired of hearing everyone saying: I have switched everything off now and still only get 2 days of use.. Why??
If you want a weeks worth of battery life get 1" non-touch black & white screen phone.
If you want a awesome phone get a Galaxy Note, switch everything on, sync your social networks and mail every 10 minutes. Browse the web on the awesome 5.3" screen, play games and enjoy the phone to the full. So what if you need to charge it every 12hours.

2 days 10 hours with light usage (1 hour screen on time, automatic brightness, few 5 minute calls, about 20 notes, apps updating and some browsing over wifi) and still have 70% left.
It depends on the user. It surely has the juice to cope with heavy use. I couldn't be more happy

Roger that, entering good guy Greg mode.
First of all, the fist charges are important. Once i bought it, i updated it to latest 2.3.6 OTA and started using it till it shut itself off. Then charged it to full while off. Repeated this circle 5-6 times, maybe more. I haven't rooted the device yet. Its 100% stock running KK5. (Europe)
As i am in places where there is wifi available, i switched data off. In wireless and network options, i use "GSM only" mode. I left auto synch, auto brightness and gps on.
Widgets. I use the stock weather, stock digital clock, battery solo widget, stock task killer, stock news and weather, stock calendar. All those spread across 6 homescreens with 39 other app shortcuts on a black/silver background.
About the light usage. 5-6 times a day, i switch wifi on for synching. I read my mail and check my Facebook messages. Once i am done doing whatever i wanted to do that requires internet (update any app that requires updating etc.), i switch wifi off.
Lastly, before going to sleep, i close all active apps using the stock task killing widget and clear the ram. Overnight, i lose 2% battery.

Now that's what I call a battery obsession!
I just use my device as I see fit, and top up charge when I can - I have a Micro USB cable on my keyring, which means I've always got a charging cable on me.
Regards,
Dave

I partly agree with you. But we lack the battery technology to do all that. Not having enough signal coverage alone is enough to drain your battery. In some ways, you adjust yourself so as to keep using the phone for longer periods of time.
I must disagree with the fact that all the above i mentioned are garbage though. I am happy that i figured out a combination that will save me huge amounts of battery. I can still do all the heavy use i need, when i need it. With smart-phones there are options in settings to let you do just that. No-one forces you to do all that, just as no-one forces me to leave everything on.
Having lost 30% battery in 2+ days, means that theoretically if i kept using it like that i would get 7 days of one charge. For example, i know when i will receive an email, from who and when he/she expects me to reply. I hardly get any emails that require immediate response. If someone expects me to reply instantly, they send an sms, or call. Both of the options work fine using gsm only mode.
I also don't find important being logged in facebook 24/7. I 'll log when i have a break, before sleeping and when i wake up. Need to check the weather before leaving for work? Tap on wifi, wait 2 secs for it to connect, click refresh on the widget, done. It doesn't take more than 10 seconds.
I don't rush to turn off wifi or anything. I just use the battery juice and the phone's cpu on demand. The note is indeed a smart-phone, but with all it's features it is reaching laptop territory. I find that treating it as a laptop works better for my needs. Then again, thats just me. If your lifestyle demands all of the note's features on 24/7, then by all means leave them on. There are external 18000 mAh battery packs you can grab.

I'm running Cassies's Lite ROM and I can get between 5 hours and one week on a single charge. Just do everybody a favor and understand that this thing can go into sleep state for days.
If I leave it alone, nothing playing or syncing on the background I lose about 1-2% in 8 hours, so this could go on for days, even a week if you don't touch it.
Of course if the screen is on for only 15 minutes on 2 days, you're not going to have much power used.
During calls screen is off, yesterday I did a 1 hour call and lost less than 10% battery. So you can make several calls on 2 days and lose litlle charge.
If you play a 3D game with screen on at full brightnees, you'll deplete the battery in 5 hours.
It's no difficult to understand. battery life depends on what you do with the thing. Whenever the screen is on, it will consume power. How much depends on the brightness level and the color of the pixels displayed.
Syncing facebook / twitter / e-mail through 3G takes a lot of power too, specially when you're on a low signal area.

Anybody noticed the difference charging the phone while off versus charging it while on.
It looks to me charging while off makes the phone battery last much longer
it also takes much longer time to charge

My old iPhone 4 did that . I was downloading an app while having it plugged in into the wall outlet, and the battery just started going down (600+ meg download).
The note is a sloooowww charging device, that's for sure.

i always get over 2 days life out of mine. i never use wifi and i have gps on all the time. But what i do is i have the screen to auto and i use the stock task manager widget. With applications i always use the back button instead of home which 90% of the time closes the app. As a browser i use opera mobile as this has an exit button too. keeping running apps to a minimum seems to help my battery las well.

I'm getting amazing battery life.
And still going strong 11hrs with somewhat light usage and it's nowhere near 50% battery yet hehehe

I'm getting 3.5 days on a charge with moderate use.
I have 4 email accounts that are polled every 60 minutes.
I make a few calls a day and use the browser a little.
What seems to help is doing a force stop on apps that I'm not using like AP Mobile and Yahoo Finance.
Also, I am runnning KL7.

With light usage, few sync's a few calls ((4-5 min) some texts and notes and few minutes of gaming.. I get a around with 16+ hours of usage easily. I'm happy with the battery and the Note can definitely get on with a more aggressive battery usage...

It will trigger automatically based on a few different criteria being met, in particular - the phone has to be left completely still for about an hour for Doze to start.

Absolutely false information. Doze starts almost immediately after its placed completely still somewhere aka a desk. I've had it sit still for 20 mins and I look at the battery graph and for those 20 mins it was completely flat

I'm sorry, but the source code doesn't lie.

My doze seems to kick in pretty quickly as well. I can set it down for about 15 min+ and I can see it flat line in the battery chart. I wish there was an app in the Play Store to tweak the doze settings without root :/ I Kind of want doze to start within minutes and not have the movement turn it off.

Absolutely false information. Doze starts almost immediately after its placed completely still somewhere aka a desk. I've had it sit still for 20 mins and I look at the battery graph and for those 20 mins it was completely flat

It doesn't start immediately, what you are noticing is likely just the low power consumption of the display being off with the CPU scaled back. Doze goes into effect when it realizes the phone isn't being used, meaning it's lying flat with no movement. I wouldn't say it takes an hour, but it doesn't start the instant you turn the screen off and lay it down either.

It definitely doesn't work right away. When doze is on, you pretty much do not get any notifications (except phone calls and other priority ones) until you pick up the phone. That means your emails and app notifications would never come on if your phone was still on the desk. And it would be pretty horrible if it worked that way. It would mean having to pick up the phone to fetch new notifications each time lol

Alarm Clock Xtreme's alarms have failed to go off for me due to Doze. Not a particularly effective alarm clock imho.

Unrooted 6P on Nougat Hot in Pocket, Cool on Desk (Project Fi)

Hi, I've had my Nexus 6P since June now and I've been noticing some issues with battery life and Android N. The weird thing is, the battery is only having troubles when the phone is in my pocket. If I leave my phone on my desk the battery drains very slowly, but while in my pocket the phone gets hot and the battery drains much quicker (e.g. a short 10 minute run to chipotle for lunch left me with 5% lower battery. My phone didn't leave my pocket the entire time).
I'm using Project Fi for service and am in Manhattan, so service isn't an issue. I use the phone with backlight settings at 50% and I don't use the screen more than 30 minutes a day on average. I have location services disabled, I'm on the most recent Android N preview, I use WiFi at work and at home. I have a Pebble Time smartwatch that is connected via Bluetooth to my phone all hours of the day. My phone is Unrooted and has no custom bootloader. I don't have any apps that contribute significantly to my battery drain.
I suspect that my battery issues are from the new and 'improved' Doze feature on Android N.
I don't have a battery breakdown handy (cause I stupidly plugged it in before screenshotting) but the top stat on my battery drain is Android System, with CPU total over 1.5 hours in a given day and Keep awake over 45 minutes at least.
If anyone has experienced similar behavior or might have a clue as to why my battery is dying and how to fix it, please let me know!
Thanks!

I turned off the 'ambient display' option in Settings/Display almost immediately upon getting the phone (which I've had for 3 days now!) I found that it would wake the screen and turn off a bunch of times if I was just carrying the phone and not actually interacting with it. I can see that being a big battery drain just for the screen time.
Good luck!

I don't have a solution, but my Nexus 6P has a similar symptom: It gets hot when it's in my pocket at work.
Based on the wifi wakelocks I've seen in Wakelock Detector, I suspect it's trying too hard to stay connected to the wireless network. We have a few access points at work, and it's possible my phone is switching back and forth between the two closest access points. It's also possible that the wifi signal isn't strong enough, so the phone boosts power to the wifi radio.
I'm on Project Fi, and I know the T-Mobile and Sprint signals are both weak at work. I don't know how much energy the phone wastes trying to keep itself registered on the mobile network, but I imagine that could also be related. Even though Project Fi will successfully use wifi to send and receive messages and phone calls, I'm pretty sure it still keeps trying to get a better connection to the mobile network (like every other phone).
It's difficult to judge whether the phone actually does something to cause a higher temperature while it's in my pocket, or if it just dissipates heat better on my desk. My pants are definitely too tight, so I'm sure that doesn't help.

Hey, thanks for the tip about ambient display. I turned it off and I'll let you know how it goes

This is pretty simple. Phones rely on airflow to remain cool because they have no active cooling. A phone on a desk has airflow. A phone in a pocket doesn't. No airflow means hotter phone. A hot battery drains much faster than a cool battery. That's all it comes down to.

Totally not what's going on. When in my pocket, the processor gets really hot, the rest of the phone warms up from my leg heat, but there is a hot-to-the-touch feeling to the top of the screen near the CPU which indicates higher clock speeds on the CPU while supposedly 'idle' in my pocket.

No luck . Still having serious battery issues in pocket despite turning off ambient display.

Meh, sorry that's not the issue. In settings/battery what is listed as using the most percentage?

Hey, thanks for the reply. The "Android System" app is currently listed as using 19% of my battery followed by android OS then Chrome.
Android System has a CPU Total of 1 Hr, 30 Minutes, 34 minutes of keep awake and 800 mAh computer power use.
My screen has been on for 13 minutes and is computed as using 42 mAh.
This is all only 6 hours after taking my phone off the charger.
Thanks.

There's a lot of processes covered under Android System. I would start with location services by switching them to off for at least a day.

Location services have been off since I got the phone. I only turn them on when needed for maps.
