GPS Off, google location services off, Wifi always on, 3g area, 30% signal loss current run time:

1 day, 17hr 20% discharging.

Screen time: 50 mins
Calls: 25 mins
Text: 50
e-mails: full push on both exchange and gmail, sent 2 emails

Granted this was very light use. On a heavy usage day for me (probably moderate for most everyone else) I got a full 24 hours on full brightness. My auto sleep timer is 1 min and the screen locks 30 seconds after phone sleeps. At work I get full signal with no drops, at my house with bad service I'm probably 50% signal loss, but due to half day at work half at home it evens out to about 30%.

It is official. This is the first device with a good battery on LTE and thin. Sexy.

I'm using the standard battery.

Calibrated? As in this How to Calibrate Android Mobile Phone Battery | Android Advices? If so, then no. Here is my screenshot of the battery page:

Not getting the best battery life but I am not a fanatic about turning things off either. I really feel that updates to the software will help with some of the battery and signal issues. I didn't have this feeling with my bionic.

So I WAS getting good battery life, but now its turned to crap. My phone was charged to 100% at 7 pm, and in the last hour and 15 minutes its dropped to 80%. That's with the extended battery.

Checked my usage, and sure enough, something is keeping the CPU awake in Android OS. Out of the one hour, 3 minutes and 16 seconds the phone has been off charger, the OS has been kept awake for 35 minutes. (more than 50%) NO idea why. I rebooted to clear everything out, and it hasn't changed.

I was getting horrible battery life, so I looked at all the apps that were running in the background. Twitter, Facebook, Google Plus, ESPN, etc etc. I deleted all of my widgets and turned off auto refreshing on everything (except gmail and work email) and it helped considerably. Turning off the GPS helped as well.

Here is a comparison between my wife's Nexus and mine. Her Android OS is "awake" significantly more than mine is.

Also, check out this picture. Look at the bars showing up at the top right and the signal strength between the two phones. My wife's phone has horrible "bars showing" but the signal strength is the same. Yet, somehow her phone has no service and it has been in and out of service all day. She got a voicemail notification at 8pm from a voicemail left at 1030am this morning.

More "proof" that the signal and battery life are related. Willing to try something? Unlock the bootloader and flash the stock images back on (boot.img, userdata.img, system.img).

Her phone's bootloader is currently locked, but when I got my phone the first thing I did was unlock the bootloader.

 

[spiff72]

Are you running a non-stock ROM?

 

[Johnly]

Lucky bastards.....

 

[astraelraen]

My phone is completely stock. I have made no changes to it other than unlock the bootloader using ADB.

Un related to the talk above, however just wanted to report.

Got the phone on launch so about 5 days using it. I was at work for 11 hours today where the service is horrible. Always barely one bar and fluctuating from no bars to one, rarely 2. This obviously drains battery. My Thunderbolt would have a hard time lasting 7-8 hours here (and sometimes didn't) while my gNex today was in there for 11hours and I still had about 20-25% when I left, then I went to the gym and made 4 calls, one of which being 51minutes.

As of right now I am at 10% with 14h 46min on the batter. So thats 1 hour of calling, 10-20 emails, a couple texts and 11hours of searching for service. Yep I am happy with the battery. A big improvement over my Thunderbolt.

edit: oh and WiFi was on too, the entire day, not connected but on.

I like to report, I'm getting great battery life. Just checked 18 hours on battery and at 32%.

I got my phone on Saturday (early). Phone is un-rooted and no changes were made to increase battery life. I do have the extended battery; got it for half price at Verizon. The battery life was REAL bad on Saturday and Sunday. I got over 10 hours, maybe 14 hours on Monday. It seems that over time the battery life increases.

Has anyone considered that it could be Light Flow? Keeping the system awake to flash the LED? Love the app and I get about twelve hours on a charge on average. Will see tonight. At 50% with 2.5 hrs used by Android OS. Will see where that stands in the am.

It must be that incredibly ugly red bra she has her phone...

Here's mine after today's use.

I bought the extended battery, was using only 3G.

I'd say I did moderate use. 20 minutes of phone calls 20-30 text messages, checking emails, browsing the web, and checking out apps in the app store.

syncing 2 gmail accounts, 3 email accounts on 15min timers, and synced with google calender/contacts; I got a weather widget updating every 3hrs, phone was on vibrate the entire time.

I took a few photos as well.

I also played 30 minutes of Sudoku

screen was on for 1hr 22 mins

GPS was disabled for most of the day, never turned on bluetooth
brightness set to auto

For tomorrow, I'm gonna have the 4G on all day and see how it goes. I will probably have more usage tomorrow. I have a busy day.

I'm guessing I can get a 12-15 hour day of moderate-heavy use with 4G on all day tomorrow using the extended battery.

I'll post results.

Okay, here's an update to this.



From 930am until 1130pm I had 4g on the entire time, GSP off for all but 30 minutes of the day.

Screen was on for 1hr 20 mins on auto-brightness

10 minutes of phone calls

But I watched some videos in HD on the youtube app.

Sent and checked a few emails as well, and downloaded and installed a few apps.

Took a lot of pictures, the quality of them sucked bad (I assume its the software, and its going to be fixed)

Browsed the web for maybe 20 minutes as well.


Overall I'd say moderate to moderate high use and I only got down to 28%.

At 1130 am I plugged in into my computer for 5 minutes to send some music to the phone which is why the numbers are wrong.

I spend essentially 14hrs on battery today.

Overall, I'm happy.
