Can anyone tell me why the Android phones have battery life issues? Here's a scenario...my friend has an iphone, i have the fascinate. We both put our phones in our locker in the morning for work. We both come out for break and he still has well over 90% of battery life while mine is down to 70%. Why do the android phones drain so quickly. Yes I could put it in airplane mode and such but my friend doesn't have to on his Iphone.
Just wondering why these phones have such a tough time with battery life. I notice in a lot of the forums people are trying different things to get better battery life. I have tried different roms, kernels, radios, etc...and really don't notice a huge difference. I am not a heavy user of my phone and it lasts just about the day and dies. I may hit the net for few mins, do some texting, and check email from time to time. I would think the battery should last a couple days just doing this...not drain when the phone is just sitting idle. Anyway just wondering about this.
Apple has complete control over their phones. Designed in house, software developed in house, and carriers have no say in the software.
I have a feeling that has a lot to do with it.

Which ROM? Of course you are aware of the many workarounds needed to keep froyo idle drain under control? These will eventually be fixed for good.
I have even more of a complaint about the active screen-on drain. Using auto brightness indoors, its impossible to get more than 2.5-3.0 hours of screen time. (WIFI or 3g) This is way less than iphone 4's capability of around 8 hours. There are some things that help explain it like androids 100% cpu usage when scrolling or animating the UI. However, there must be massive differences in the screen power consumption. Yea, yea, SAMOLED, power draw depends heavily on displaying black vs. white etc, but my random usage never gets more than about 2.5 hours screen usage over a day. Say what you will about apple, but they optimized the hell out of battery life.
Which kernel are you using? After moderate usage for me (games, browsing web with wifi, phone calls, etc) my battery life is around 70% after 15 hours.

Guys, since screen-on time dominates battery usage, it'd be nice to note how much screen-on time you get and your brightness setting. Defining "light" usage over a number of hours could mean just about anything... very subjective.

True enough. I set my light to auto and since im usually in a room, the light setting is at lowest. When im outside, its goes to the brightest settings.

If you use Google Navigation and constantly force rerouting to destination by taking wrong turn/path, your 100% charged phone would hit empty within 2HRs or less with the screen brightness set at minimum.

We have a more powerful phone than the iphone 4, of course our battery is shorter. (better screen, faster cpu, etc) Also seems like our antenna is the best according to the review.
Android is made to constantly sync with the internet for updates and notifications. It's just the nature of the operating system to draw a lot of power because in theory it is a more powerful and complicated system. Also keep in mind that the battery inside an iPhone is huge and it is lithium polymer which lasts longer but is more expensive. These larger lithium polymer batteries are the main reason iPads and MacBooks get good battery life as well as their less powerful chip sets.
EDIT: Oh, and also iOS doesn't use as much RAM as Android so that also factors in to the battery life being generally better.

I appreciate the more open, easy to modify nature of android over apple. But to trying and explain the 2x worse battery life on android as arising from "better" processor and screen is wishful thinking at best... blatent android fanboy propaganda at worst. We need to learn how apple has optimized things, not turn an overconfident blind eye.

It's unfortunately that the Fascinate lacks the monthly software update support similar to Apple, but using the support from this forum by the devs, I had achieved 1% power usage for every 3 hour idled = max possible 300 HRS.

Guys, there's a lot of android fanboy propaganda going on in here. I'm not against android, but don't automatically defend it like its your mama. The ifixit link below shows iphone 4 has 1420 mah battery as opposed to fascinates 1500 mah. They also both have 512 MB RAM. So that's not the issue.
Also, the Anandtech tests were done with phone on and active. So are you trying to explain android was at a disadvantage because it was "doing things in the background"? Like what? Any background process or sync service that kills your battery that bad is implemented horribly. iOS is doing the important stuff in the background too... maybe just not the ESPN or weather widget. But no one in their right mind believes those things are the problem.

Sadly, I am the opposite of an android fanboy as I would have gotten the iphone for verizon asap if I havent gotten the fascinate back at November. (Iphone on Verizon were still rumors back then). Also note that review was done in October last year. Battery life is probably much better now with cleaned roms and froyo.
If you really need to browse the web over 4 hours a day on your phone (use computer?), why not just get a larger battery or even get the iphone?
Edit: Hardware mean a lot in battery usage. After checking the iphones CPU, seems like its pretty much the same or similar to the ones of the fascinate, except slower clock speeds.

Personally I don't get any better battery life from froyo ROMS. My wife's fascinate with stock eclair usually gets as many if not more hours of screen time as I get with superclean 2.9.2 and jt's EC10 w/ slight undervolt. Sometimes I get much worse battery life when I forget to activate one of the 10 workaround hacks still needed to fix the idle drain issue.
I use 2.5 hours of screen time daily quite often and find my battery exhausted before the day is over. Maybe I'm the rare case, but I doubt it.

My battery life with imnuts undervolted kernel is much better than ones from previous EB01 kernels. I didnt find much difference between SC 2.9.2 ROM and Nameless V3 battery with the same kernel. I usually have around 75-50 percent battery life left from moderate usage. (Different from other people according to screen brightness and etc as stated in previous posts)

Under battery details, what is your display "time on" at end of your day? What is Max "time on" you ever got? Without those numbers its hard to say anything objectively.

Since its monday tomorrow, ill test the max time on. At the end of the day, or rather when I start charging it again/installing kernels or roms, time on is 14 hours and 17 minutes.
On my fascinate I unplug phone at 645 check face book and xda for about a hour on auto brightness. I then go to school and check pulse and xda many times totaling around 2 hours. The rest of the time is idle so after 2-3 hours of screen time and then 3-4 hours of idle during the school day I get home with 85-89% left im using dark revenge with imnuts undervolted kernel. Im no android fanboy I'm just posting my stats.

Nexus 4 Average Battery Life - How many hours you get out of your phone?
So far getting 13 hours with medium brightness.
Its not the total on time that really counts, it is the screen on time. And go to the great battery impression thread in the general forum!
Just finished getting 1d11hrs from it... I had run it down to 1% and fully meant to take screenshots when the phone shut down on me I had done "average" use as I use a phone... watched a little bit of an hd movie, facebook, a few calls, playing on google play and other stuff.
I'm coming from a Samsung Infuse and this is about on par with the battery life I was getting from that running CM10 unofficial on it when the ROM didn't have drain problems affecting it.
I don't know if this isn't typical of others' experience with the N4... I was cautious and plugged my baby in when I got it before even turning it on and let it charge up. It did have to do some calibration as with power off it thought it was at 100% but when it booted up, it registered 80% charge. Now after a few full drain/charge cycles it seems to have a very good feeling for 100% and 0%.

Even though i wasnt able to get my hands on it, my cousin did and he says he got 6 hour on screen time and at total of 22 hours for battery
Where are you getting this battery life? I get max 5 hours of moderate use Facebook twitter tapa talk, a game or two what gives?

Total battery time it differs but my screen time on average is around 4hrs.
Very low brightness, wifi always on.
I only use a few apps like sms, tweet lanes, instagram, flipboard, and espn.
I get 9 by barely using it. This phone has a serious problem. It's obvious because the Optimus G is a battery boss, and it even has LTE.
This phone had the exact same screen, internals, battery.

That's where you know it is software related. 4.2 has some bugs, the galaxy nexus got updated to 4.2 and people are reporting really bad battery life ever since the update. Also JB in general doesn't perform as good as ICS in the battery department cause of project butter that cranks the CPU up soon as you start using the phone. Example is Galaxy s 3.
Personally i get very good battery life and in very satisfied. When i was on stock my battery started really bad but then improved, now that I'm rooted and running a custom ROM and kernel i have very satisfying battery life.

I'm considering buying Nexus 4 and after reading various reviews and user opinions my only concern is - how is the battery life?
Some are saying it's great, others are saying it's crap... See me confused.
I've got no intention of using it for watching movies or heavy gaming, but would still like it to last me at least whole day without charging (24 hrs).
Currently, my SGS2 lasts from 1,5-2 days without charging (I'm using JuiceDefender).
Can anyone comment on the subject, especially compared to SGS2?
I had a galaxy s2 before the nexus. Compared to my s2 the nexus pisses through power mainly on WiFi and surfing the web. Location services and google now use battery a lot too + overnight i loose more power compared to thr s2. I'm hoping its software related and Google improve battery in updates to JB.
I don't believe those who say the battery is great for one minute.
Pretty damn good so far for me my SGS2 would be dead in half the time, even with the screen off!

Depending on the apps you use, battery drain can be a huge downer for this phone. I use eBuddies for aim chats at work and that thing drains through, so does GChat. Navigation apps such as Google Maps or Navigon also burn battery like there's no tomorrow.
So the question of battery life really is dependent on your daily needs. The difference with other phones is that some have removable batteries.
Expect to invest in a mobile recharger, or to have spare charge cables always on hand with this phone.
I don't do much with my N4 during the day and came over from an SGS2. SGS2 by far outperforms the N4 on battery life from my experiences.
It seems the N4 has fantastic idle battery drain. I let it sit a full 7 hours over night and lost 3% battery, but it seems when you're actually using the phone, the battery is middle of the road. I'd say its still better than my S2 and as good, or slightly better than my S3. :good:
Hey Guys,
A bunch of people are complaining about the battery life on Nexus 4. I've been waited for a couple days since I got the device, to have enough confident about the battery before I make any post here. Yes, the phone battery drain pretty fast on the first few cycles. After a bunch more charges later, let me tell this, the battery life did get significantly better. It lasted about 10-15 hr depends on the load of the usage.
Here is my typical day, off the charge at 100% in the morning, listen to a few songs, checking emails, and messages while getting ready for school. About an 30mn to 1hr of internet browser and youtube videos while on the bus. By 1-2pm the battery drop the about 70-80%. I put the phone in silent mood til i'm done with all my classes. On the way back home on the bus, I listened to a bunch of music, web browsing, maybe a few phone calls, texts or games.
Compare to my old phone, Samsung Galaxy S2 T989, im impressed with the Nexus 4 battery life. My Galaxy S2 battery always die on the bus coming back home. What I'm trying to get at: if you're a light to medium user like me, then get this phone. I was hesitate at first because I always have bad experience with android battery life. But Google seem to get its OS right with this nexus device, mainly because the battery drain minimum while in sleeping mood.
Can you post your Nexus 4 battery performance screenshot if you have been using the phone for more than a few days ?
Is there supposed to be a question being asked? Or a statement as this is in the Q&A forum.
I agree with you on many points. People need to wait at least 5 to 7 days for the battery charge to fully kick in. The first days mean absolutely nothing as it is still being aligned plus the user is still installing apps and setting up their phone.
There are some notable problems in the default kernel that uses more battery Usage than normal too.

Depends on how much screen time you got, which you didn't show us.
The trick is to be careful about using mobile data when signal is bad, I switch to WiFi when home to avoid unnecessary battery drain.

What is this obsession for battery life, it lasts me well through the day with moderate/heavy use. I charge it at night (if needed) and unless you are homeleless this shouldn`t be a problem. It`s a great phone and i enjoy using it.

I thought the same until my N4 actually arrived, it seems battery life is abysmal compared to my Optimus 2x which didnt have anything really spectacular in regards to battery size. On my O2x I could get 1.5 - 2.5 days depending on use, hitting atleast 1 .5 which was good and acceptable for me (I can charge at night anyways) however my N4 doesnt even reach 13 hours on similar usage!.
I am quite a light users of smartphones however I do like to have a power phone when it comes to using it on the basis of smoothness and capabilities if I need to say do work on my phone, I rarely play games though. Main usage is 2 email accounts on poll 1 hour steps, a third account that is an exchange server and polls in 30 minute steps and thats about it with some brief browsing and a handful of texts (been a quite time since I got my N4), this is less usage than my O2x and yet it still performs alot worse!
I was hoping of staying with stock as I was expecting it to finally be good, comparing it to LG stock attempts it is but battery life isnt . I will be trying the combo Vangelis13 mentioned, raspbean and matr1x kernel as that seems like a great mix however Parandroid has been on the table and it seems like alot of being are getting good results so I will try it soon .
If I can get more than a day of usage I would be really happy, if I was playing games or doing really heavy tasks I wouldnt expect it to last but right now it is doing pretty much nothing and dieing far to fast!.
One thing I've noticed since coming to N4 from S2 is that phone calls drain battery much more significantly on the N4. I could make an hour long call on my S2 and it would use no more than a couple of percent battery but the N4 used 15% for an hour long phone call the other night.
If I didn't own a nexus 4 and came to this thread to find out about it's battery life I would expect it to be good.
Point is you guys are misinforming everyone. The battery is mediocre and that's it.
It won't last a full day if you use it constantly and I do need two charges / day many times.
Let me put it this way, you will only get roughly 3 hours of screen time on stock everything. If that is good for you then it's will have good battery life, if not then you will say it's got poor battery life.

you are perfectly right.
I come from an iPhone 4s, which I changed because the battery life wasn´t that great and I thought it was time to try something new.
Got the N4 last friday and played around with it during the weekend.
Monday, tuesday and wednesday this week... none of these days I´ve been able to come back home with the phone still on.
I wake up at 7.30am and I usually am back home at 6pm.
In my opinion, and honestly should be in everyone´s opinion, 10 hours of battery life are unacceptable, whatever the usage is (considering that 7.30 of those 10 hours I was at work)
I have till friday this week to return it, which is a pity because the phone is great
i get 5-6 hours sot..
rom is omnirom 5.1.1 hellscore kernel b73.
100mv undervoltage hellsactive governer.
think 7 would be possible if google services would not take a quarter of the battery.
the screen is not taking that much battery as one would think.
think most issues with battery life come from fake original battery replacements.
had 3-4 sot using "original" battery. but after replacing with real genuine from official lg spare parts shop 5-6...

This video shows that the Galaxy S5 with Snapdragon 805 and QHD Display doesn't use more battery than the "old" Galaxy S5. So Samsung seems to have found good ways for battery saving.
I am not concern. I plan to get 2 extra battery and a external charger. The Note 3 version was like $30. Whick brand is good? Anker?

You would be correct. The Note 3 Battery life was pretty damn good. I never had issues with it, and if you look over the N3 forum you'll see some pretty outstanding results :good:
I expect the N4 to have been tweaked a little and the battery to be either on par or at least very very similar to the N3.

The Note 3 was widely regarded as having some of the best battery life for any phone of that time.
If anything wall hugging iphone users have something to be worried about with their copycat device, "Retina HD" welcome to 2012 Apple and the battery size, hardly a mention because we KNOW its smaller than Samsungs.
My note 3 has pretty decent battery life. Just make sure to disable a bunch of stuff that you don't need for best results.

Even though I was disappointed they didn't include a bigger battery, I'm not concerned about battery usage on Note 4. I don't think they would've made a big deal about battery usage the and better performance on the Note 4, if they didn't have something to back that up. It would've been much simpler to not mention the 7% improvement, or just say they increased the battery by 20mAh. I'm expecting a somewhat better performance compared to the Note 3, which is fine.

The battery is still bigger than the iphone 6+'s and you can always swap it out and with quick charge feature 0-50% in 30 minutes, how long does an iphone take?
It's not how big the battery is, but how it's used. I have Note 3 and I saw as much as 40% drain overnight, when phone was not used at all, right after updating to KitKat and I also managed to have as little as 1% drain overnight, after killing some of bloatware. I can't pinpoint anything in particular, but it could be more than one program. Right now for example Google search is draining my battery more than all other programs combined and I'm not doing anything with the phone at all. I don't want to kill it, since I use it sometimes, but if it keeps doing it I may have no choice. Anyhow if Note 3 is working properly it can have fantastic battery life.
According to what I read so far Note 4 screen should be something like 14% more efficient than older version, despite having higher resolution, CPU and rest of hardware should be at last as good as older models and there should be ultra power saving mode, so I wouldn't worry about power that much, unless some program or programs crash and go bananas, but at least software issues can be fixed, just a matter of effort. For example many claim factory reset fixes excessive battery drain right after firmware update, which I had personally.
If you are concerned, you could always buy a ZeroLemon battery.
Here's the report on Note 4 screen. Remember display consumes the most energy of anything.

Comparison with the Galaxy Note 3:
The Galaxy Note 4 is 14 percent more power efficient than the Galaxy Note 3. This is due primarily to a 19 percent improvement
in the power efficiency of the Green Primary channel (materials and electronics). The results are scaled for the same Luminance.
Comparison with LCDs:
While LCDs remain more power efficient for images with mostly white content (like text screens, for example), OLEDs are now
more power efficient for mixed image content because they are emissive displays so their power varies with the Average Picture
Level (average Brightness) of the image content. For LCDs the display power is independent of image content. OLEDs have
been rapidly improving in their power efficiency. In fact, the Galaxy Note 4 is 40 percent more power efficient than the
Full HD LCD Smartphones we tested for mixed image content (that includes photos, videos, and movies, for example)
with a typical 50 percent Average Picture Level, APL.

SOC should use the same power as other Snapdragon 805 powered devices (hint: Qualcomm generally makes pretty power efficient smartphones).
