Official Battery Life Thread

[gmen78]

I have two batteries, both charged completely and going through my 4th cycle with each. 4g radio is off, screen on auto brightness, playing games, browsing web, moderate to above average use and im getting 25% drop every hour on both batteries. Thank god i bought the extra battery. Lil dissapointed but not a deal breaker.

Yes,

Apparently it's totally the screen. If I let it just sit there it may last days without even going down 5%. It's the opposite of my Bionic which would lose power doing nothing.

Right now 49% left and 6 1/2 hours off the charger. Screen time 1 hour 20 min.

I downloaded Screen Filter to use at night which is wonderful - and it should save battery life.

You stop them when you are done using them, or the ones you never use that are pre-installed?

Both.

If it says that it's Running, and I'm not using it anymore. I immediately Stop/Disable it, whichever it says.

If you do some math calculation, you can easily get the number of percentage the screen consume per each hour. In my case, with automatic brightness, I came up with 12%/hr. So, if you were up with screen on for four hours, you have consumed almost 48% of the entire battery, just with the screen alone. Considering that when screen is on, mobile data and CPU also drain a lot of juice, heavy or continuous usage more than five hours would eat up most of your juice.

P.S. - of course this is in my case. The actual consumption rate will vary from phone to phone, due to the brightness setting and background color.

I think it's better to leave them alone for the same reason why you shouldn't be using a task killer. If you remove an app from memory, your system will have to fully reopen it again and use more resources than if it's sitting there in memory and ready to be pulled up again.

Here is my battery life situation. My battery life is abysmal, but I know better than to return it after a day (been using smartphones forever). Thursday night I put in my extended battery and charged overnight. Friday I took it off the charger and immediately turned off LTE. I set screen to 25% brightness, wifi on. I managed to kill the 2100mah battery in 10 hours (7am to 5pm). Screen time or actual usage was approximately 2.5 hours. Friday evening I took the phone back for an exchange due to the earpiece sounding like it was blown. So today I put brightness at 20%, LTE off, and this time no wifi to test out the 3G connectivity reliability. I took it off the charger at 9am and when I got home at about 7pm (again 10 hours) it was at 6% left and just under 2.5 hours of screen time.

So that is two phones with just about the same battery life on the 2100 extended. I put it on the charger just after 7pm and did a factory reset. I'm going to run the phone the next couple days without loading it up with all my stuff. I may not even put FB or anything on it. Just use it completely stock. I'm going to give it several days to see if the battery life improves due to the OS learning the battery or whatever it does after several cycles. If I don't see an improvement by Thursday, I'm going to exchange the extended battery. Then I will put it through its paces again for several days/cycles. All of this time I will keep LTE off permanently. I don't need it.

If I cannot get the 2100mah battery to last at least 16 hours of being off charger and about 5, preferably 6 hours of screen time, I have a decision to make. I absolutely do not want to return this phone. It's so incredible. As much as I love my iPhone 4, I love the Nexus more in its own way. If I can't get it to meet my day to day uses I'm so tempted to just reactivate my iP4 and use this as a mini-tablet. It's that awesome. My only other option is to get the iP4S but I can't see using an upgrade and paying $300 for basically a slightly better camera than my iP4 (I won't use Siri). I think I'd rather keep the Nexus as a mini-tab and also maybe with the development there will be a kernel or something that will dramatically improve battery life, then I can reactivate later. Decisions decisions.

16 hours? WTF? there is not a phone on the planet that will get 16 hours. not even a 4S. You do realize that the 4S with dual core and multitasking is not near as good as the 4. in fact it has 50 hours less standby time in its specs. not sure how much less talk time. it is just a fact of life. you are expecting something completely unrealistic. you do realize that the nexus has a 4.65" HD screen right? Four point six five!!!!!!!!!!!!!!!!!!!!!!!! HD Super Amoled. im afraid you bought the wrong phone! im also afraid you wont be happy with any phone other than the bland tired 4 you have now.

In fact, he can technically get 16 hours, or even more. Look at the attached screenshot of mine. I am at 9 hours with 75% left (0.5 hour on-screen time so far). At this pace, it could even reach 36 hours, theoretically.

However, not with 5 hours of on-screen time. On average, GN display will consume approximately 12% of battery per hour alone. So, to be on for 5 hours, 60% of the entire battery should be used just for the display. If we add CPU and LTE, there is no way his GN can reach 16 hours. He could reach 16 hours if on-screen time remains around 2 to 3 hours, maybe?

Actually, there are many iPhone 4S users getting more than 16 hours and some are getting 24 hours or more on a single charge.

Check the screen shots. Some are for ip4s.

bought this today!

My battery drops about 1% every 3 mins. Even while having low brightness. Im very disappointed thus far with the battery life. Ive read in a couple of places that the first few days will be tough on the battery, not sure how that works but im hitting my first 24 hr mark now and im crossing my fingers it gets better. I purchased the additional battery with the charging kit yesterday. I took my phone off the charger at 7am this morning with a full charge, by 11am i was putting in my 2nd battery only after moderate use, texting and a bit of web browsing. Hope this gets better.

I am in the same boat as you are, killing the battery in about 2.5 hours.

https://t.co/N9zdiVy1

I really hope that this gets better, I have the spare battery charger kit, but 6 hours on two batteries is still not acceptable. Just turned off the NFC and GPS, and we'll see how it goes from there...

 

[thescreensavers]

73% after 6hours 30 min, its not bad at all

I have it set to 3g only, and use 4g when I need to.

People having battery issues check your partial wakelock usage with better battery stats

 

[Andrew Ruffolo]

Ive narrowed it down to an app. I uninstalled all my apps and battery is spectacular.... havent found the culprit yet.

 

[byrds8]

Anyone else notice it discharges a lot over the time your sleeping? Something in the neighborhood of like 10% is what Ive noticed. Im not sure about the battery life on the phone just yet. I saw it drop 7% in the first 45min yesterday and hadnt done anything but talk 12min on the phone. Battery life does seem kinda wonky though. Android OS seems to eat a lot too.

whichever one it is, probably isnt ICS optimized, right?

 

[Andrew Ruffolo]

Honestly... I had at one point over 150 downloaded apps (and I went app $hit [see what I did there] when the paid apps were 10 cents). I'm going to slowly add apps as I see fit to see if its one of those. Whatever it was, was killing my battery just being on the phone, not even being logged in. Facebook has a history of being the culprit, but I hadn't even signed into services yet. I can get an app list of what I had on it and maybe we can cross reference. In its current state, I was able to charge the phone on the car charger while having bluetooth connected. I passed out last night at my sisters and left it off the charger. I woke up an hour later than I normally do and still had 69% (the night before, it died without use). My sister was playing with my phone a little, too (she got me into android phones).

while the battery life is not fantastic, I am feeling better than I did with the Bionic at this point. I have been playing with this thing non-stop. I set everything up and then unlocked & rooted. Then I went back to setting up the phone again. I think I can get about 8 to 10 hours but I admit that I need to bump charge to make it through the entire day. I also have been leaving GPS and NFC on full time. Does anyone know if the latest bionic update helped with their battery troubles? I am hoping that future updates will help us get a little more battery life and improve the radio reception. I think this will be a keeper but day 14 we will know for sure.


Edit: I have yet to turn on Wi-Fi, I guess unlimited data has spoiled me. I will try today.

Maybe I am an anomaly here, this is with wifi a lot since I have been at home most of the weekend. I also have the extended battery.

Night and day difference:
with all my usual apps installed (no services signed into)

hardly anything installed:

Notice:
2nd picture was almost all in 4G area
1st picture to try to salvage some life, I stuck it in 3G only mode... and it actually dropped down to 1x :/
I will attempt to find the culprit, but honestly its going to take me a while.

 

[davesax36]

I think think that 25% in 7 hours overnight just sitting there with 4g on is a bit fast. I actually get more consistent 4g signal at my house than 3g. I left it off wifi just to see how it would do. Here are shots from yesterday and this morning

I know this isnt about the battery but when I was poking around why is the gallery showing up under data used for the phone?
