[Q] Battery life question (before buying)

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!

Who watches porn on a small screen vs a huge monitor? :silly:
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:

Can't believe Nexus 4 has significantly worse battery life then SGS3

Currently using both my s3 (daily driver for 6months prior) and nexus 4 while waiting for buyers to show up for the s3. Both running aokp with custom kernels and huge undervolts. My s3 as experienced for the past 6months can easily last through a full day's (12hrs) usage, running consistently more then 5 hours screen on time with 10+% batt to spare.
Given the massive hardware and software evolutions in the n4, was expecting it to outdo or at least match the batt life of the s3, of which it shares a similar battery capacity with. Much to my horror, it can barely last 75% of the s3's batt life, even after using faux's amazing kernel/app combo to uv by 150mv. I find myself scrambling for the charger outside home for the first time in ages, halfway through my work day when screen on time has barely even reached 3hrs.
I find this utterly unacceptable given how on paper everything about the nexus 4 points to a more battery friendly device:
28nm next gen snapdragon vs 32nm last gen exynos
IPS LCD is more power efficient then AMOLED esp with the common white backgrounds while surfing net
Latest qualcomm 3g/baseband chip built on power-sipping 28nm tech
android 4.2 pure google developed OS + open/documented cpu libraries vs closed source code relying on inefficient blobs
no microsd to power and constantly read from for n4 (might not be a pronounced effect though)
Kindly post your batt life experiences with the n4 and if you concur with my observations, else i'm afraid i just got bad set or a faulty battery.

I am sorry to say this but your title is stupid like you know for sure that the battery in the N4 is bad. Then after your ranting you ask people what their battery life is to see if you have a bad battery. If you saw the other threads people's battery can last up to 1 day and few hours, just depends on how you use it. I usually get 20 hours with normal use which is more than enough battery life for me. It took a while until I got my battery life to be good. It did suck before hahaha

Sounds to me like you didn't do your research.
A lot of people are having issues with undervolting on the Nexus 4. You should go back to stock on it and just let it be. It's perfectly fine all by itself. I get solid 18-24hr charge cycles with similar screen on time to what youre talking about.
The great thing about this phone is that we're able to change basically anything we want to.......but just because we can, it doesnt mean we should.

I've read on phandroid.com that Google is working on a patch that they will release for the nexus 4 that should be fixing the battery issue. Just hang on until this patch is released.

I'm getting pretty good battery life using faux's kernel.
Almost 10 hours off the charger and almost 5 hours on screen with a mixture of WiFi and hspa.

[Q] What counts as good or bad battery life?

I usually have to recharge after beeing 20 hours on battery and I usually have about 4+ hours of screen on time, and the battery is around at 30% after this much usage.
Today I used it a little bit more, it's been 16 hours since fully charging and I've had 6 hours of screen on time before when I was at 15%.
Is it good/neutral/bad battery life? I almost always use my N7 at home, so it doesn't really matter, I'm just curious.

Not sure you will get an accurate answer on this topic.
Since everyone has different usage habits, it could be tough to determine what's good and what's not.
I know I can go days without charging my N7 and the screen time is usually around four or five hours.

Sounds similar to my battery life.
I like Android but I have to say, my iPhones and iPads have ALWAYS blown away every single Android device I have ever owned when it came down to battery life.
I still like my N7, but it's just slightly sad

Well I believe androids do a lot more than apple products.
No real multitasking on apple products which could effect battery life.

There is real multitasking on apple products, they have opened up multitasking capabilities to devs moreso than in years past, don't forget about backgrounder!
I like my iPad and N7 about the same really.

Note 4 battery anyone concern?

I had the note 3 the battery was terrible and i really thought we'd be getting atleast 4000mah as some websites stated but 3220mah aren't you guys concern? Seems like a joke to me.

I was under the impression that the Note 3 had pretty good battery life... at least that was what I was able to discern from reviews.
Can someone else who also owned the Note 3 chime in?

Watch this and you won't be concerned about battery any more:
https://www.google.de/url?sa=t&sour...Ot9BGMeI02GwNY_Zw&sig2=jB_BFvUf5EMKyJdT_ZwXOw
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.

since 4.4.2 update WiFi battery usage increased. so i got battery drain...
But i change setting to turn off WiFi when screen off and Battery Life became normal
On Note 4 they claimed for more optimization for power + UltraPower Saving mode...
so we have to wait for reviews and our experiences...
:good:

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.
http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm
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).

Note 7 battery life longer than note 4?

I realize the note 7 has a slightly larger battery and up to date internals. But has option for on always time clock on etc. So will the new phone offer at least 20 % more battery screen on time. Any thoughts. I enjoy my note 4 but Im prepared to let go off my infra red and removable battery if I get a longer battery life. Not too bothered about the Iris scanner waterproof etc. and the note 4 camera is great.
Shame we don't know much about the new Nexus or LG. Maybe 4000 battery.

It's still unclear how it will perform.
If you could wait a bit let others buy/test it first!

The battery life of any device is subjective to the individual user. As everybody uses their device different. I can get up to 2 days battery life with my N910C as I turn it off once I get home since I have a landline.

As the note7 comes on the same SOC as the Galaxy S7, we can expect an improvement in battery life. The S7 plays in the top legue when it comes to battery life, so its likely the Note 7 will behalf similar.

I won't bother to buy the Note 7. Eventhough it will definetly have greater battery life (see comparison Note 4 and Note 5), this will never replace the benefit of a removable battery. Considering the numbers, it may have 20% longer battery life then the note 5. But since I get approx. 5.5 hours of SOT with my Note 4, I don't see any point in upgrading until the phone dies.
But if you are just focused on the battery life: Taking the value of your note 4 into account (approx. $300), you would spend $500 just for 20% longer battery life (your estimation)? Thats insane man!

Good point thanks but if I get 20 percent more and a better camera plus waterproof and stronger screen.. I'm tempted

i got my new 6800 mah battery, in 1 or 2 days might i will made a post about it, i need to calibrate at all, but take some long time, u was using antutu battery test to drain it, just get around 5 hour of SOT whit max brightnes, from 99% to 7%, and i remove the battery and put again and... 35% again on battery, i open a game and drain to 7% and the phone just shut down, i remove the battery again and put it and the phone keep on for some time more, i reach 3% and i turn it off, now i put the charger, ita at 100% but i will leabe for 2 hours more, i think i need to drain to 0% one or 2 times more, but well it work perfect for me and dont make the phone line a brik like de zero lemon one
PD sry about my english its bad an i know it
