Battery drains fast!

[WookieClaws]

I'm experiencing something very close to the last poster. I was out and about Friday night and using my phone a lot and the battery last 2+ hours. I swapped to a 2nd battery and got another 2+ hours.

On Sunday I was home, on wifi and using the phone here and there. The battery went almost 13 hours, but the screen on time was 2.5 hours.

That seems to be the magic number, 2.5 hours of screen on time. I bought the external battery charger for convenience but it came with another battery. So for now I will swap batteries (have 3) around so I can use my phone like it was meant to be used.

My phone just lost 8% in 50 minutes with no use at all. None at all. Android os 51%

All the time it was on standby. Something is running in the background killing the phone.

You need to investigate the "Keep Awake" bug. Sure sounds like you've got it. Settings/Battery and then press on the Android OS on the chart. You can then compare your "Keep Awake" time to your total battery time and to your screen time. Ideally the Keep Awake time would almost be equal to the screen time.

Good luck.

Screen is at 12 minutes. Keep awake at 51. Extremely light use of the phone today and the battery still goes on standby.
When I first got the phone it was better on standby even on 4g.

How do I investigate it idk what to do?

I want to a factory reset but how am I gonna get the screen and the apps the way they are now. I don't wanna redo everything

Check the picture I posted.

By the time its ready to charge it usually is at over 4 hours of awake time. Generally like 4.5 which is a lot. When I use the phone it dies even quicker than it did before because I think something is running in the background.

I feel like settings change on its own and do whatever they please to kill my battery.

Before i returned my Galaxy Nexus, battery life was absolutely horrible. Dont say anything about battery conditioning because after 3 weeks it didnt change at all. If you don't touch the phone itll make it through the day. I had Gummynex installed with the kernel and juice defender, nope it didn't work. Using the web for 5 minutes drained the battery 8 percent literally. I was literally scared to play any sort of games on it... if you are always near a charger it's fine.

Sorry if this is a dumb question but the battery life runs different on Wifi right? When I'm on Wifi I can easily get 22 hours at least

I'm getting 16 hours normal use on codenamedroid 1.1.1 ....nearly a day with minimum use. IMO 1.5.1 exp6 kernel and jakebites leantweaks.

I think a lot of folks were quick to jump ship on the nex. Which is understandable considering how poor battery life was on stock.

People have weird expectations for battery life.

You won't get more than 3-4 hours of screen time with the extended battery. 2-3 hours without it.

If you aren't using the screen much you should easily get 14+ hours without charging it.

If it's draining with the screen being off then you have a program draining it or a bad unit or battery.

Its not weird expectations. Its normal expectations. I've had several androids they have pretty bad battery life. And no this phone before conditioning had amazing battery. 4g on standby battery did not budge at all. But now suddenly its acting up. 14 hours is pathetic. IPhones get over 30 hours. I understand they have a tiny screen and all that stuff but they don't drain because of problematic batteries or such things. Androids do. Because you suddenly downloaded a bad app it starts to drain. Why is there no built in function to let you know what program is killing your battery.

P.s. I'm not getting 3 hours of screen use. I would love to be getting that. My keep awake time on android os is five hours. What can android os possibly be doing that it needs to eat 35-50% of my battery. My thunderbolt android os was below 10%

Theres no logical reason for this battery drain. When I put my phone down I wanna be able to turn on the screen half hour later and have my battery not budge.

Or I would like to text without killing my battery.

I would have liked to reply to this topic without my phone going from 51% to 47%...I'm a fast typer

This seems to be a bug that affects a number of phones and but not most. Apparently there are, or can be, several causes: 1) Pressing the power button to put the screen asleep. On some phones when you do this the screen never actually goes to sleep. Some can get around the issue by simply setting their screen timeout to 30 seconds and then letting the phone timeout when they are through with it rather than tapping the power button. 2) Here's one of the things that Franco (the kernel dev) says is an issue:

Google Talk Video version opens the camera during boot and its sensor gets fired up and since the camera isn't closed the sensor just stays there open in the background wasting battery like there was no tomorrow. Opening and closing the Camera after booting up closes the sensor and then the GN enters in Sleep mode just fine (easy to check with Cpu Spy). If more people can confirm my initial testing then we may "have" found one of the possible battery drains when the phone is idle.

3) Franco also says that disabling the DRM Content Storage in Settings/Apps/All will also impact this issue. 4) I have found that using Franco's kernel with almost any rom solves the issue on my phone. YMMV!!

And you really think that is normal? Or occurring with most other Nexus phones? It never crossed your mind that it is either something defective, or something that you are doing differently than most others?

I have a couple things I would like to see addressed with my Nexus, but the battery life is a positive on this phone. It has exceeded my expectations, and oddly enough, seems to be improving.

I initially bought one of the extended batteries when they were $25. I assumed it would be mandatory given the impressive hardware and huge, brilliant screen. I used it for awhile and then my Seidio surface case combo showed up and I needed to use the standard battery to fit the case. I have found no issue running the regular battery. The battery life, on a properly functioning Nexus, is excellent and far better than I thought it would be capable of given the specs. I know battery technology hasnt improved that much, so it must be something within 4.0 or the Nexus.

Ugh some of you guys have battery life that DOMINATES mine... and I just missed the 15th, on which I could have gotten a brand new unit. I DO NOT WANT a refurb, no way in h**l. I don't care "how good" a refurb is, I paid $300 CASH for this thing, and I want it to work RIGHT. I am really, really getting frustrated with my battery.

Funny thing is? 4G signal has improved like crazy on my phone! Was getting -62dBm earlier! But the battery, man, it just won't stay alive! ARGH

I'm going to Verizon tomorrow and demanding a new battery, and if the battery isn't the issue, I'm just going to raise H*L* in the store until I get a brand new phone. I've already been blown-off by a number of "customer service" reps, so if the place where I bought the phone doesn't do something about it, I will be calling VZW Corporate and the Better Business Bureau! This is seriously ridiculous!

I should not have to carry my charger and a car adaptor with me EVERY TIME I LEAVE THE HOUSE!

/endrant

Ugh, sorry... I am just getting fed up. Background data disabled on most apps, on WiFi constantly (pretty much anywhere except in the car), I "conditioned" the battery properly when I first got it, and I have done everything else. I have NOT rooted it, because I don't believe I should have to void my warranty to get a functional battery life.

Is anyone else as aggravated?

I am not rooted either. If you have problems getting a new battery, I would say you are doing it wrong.

Call Verizon and explain the situation. Tell them that your battery is not functioning properly, and that you have researched it, and see that most folks get better battery life and that you have determined your battery is defective. Tell them that to correct the situation, and keep a loyal customer happy, they need to put a new battery in the mail tomorrow and include a return label with which you will return the defective battery.

Very simple. If you are polite, they will accommodate you.

ETA- I am literally taking NO extra steps to maximize battery life. I dont use auto brightness, I dont worry about what is running, etc. My phone is usually on CDMA because I dont get 4g at my office. I always have wi-fi on, I always have GPS on, I never use bluetooth. I have no app's designed to increase battery life. I charge my phone overnight, and usually it doesnt go back on the charger until the next night and I am a moderate to slightly above user.

I think the android os issue occurs in a lot of androids. And battery drain is normal too for androids. Android as a platform has some things that repeat in all their phones.
