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.

How is the battery Life compared to Galaxy Note 2

Hello,
I am searching for phone with a good battery life. The newest reviews give the S4 really good battery life scores. But I am more interestet in real life tests by XDA members.
After looking at the battery posts in S4 forum I have to say that I am not really satisfied by the stats the user post.
The stats are really so medicore, that I sometimes really had to laugh.
How about the battery life compared with the note 2?

Not as good as the Note 2. Better than the GS3.

I heard that before, but I am not sure after reading the latest benchmarks.
Here is one for example. Just scroll down and press the "+" button.
The degree S4 scores is quite different compared to early reviews.

How can you compare the 2? The gn2 battery lady's forever, on my g's 4 depends on the usage of it go soft on it the most I got out of it is 5hrs screen on time with 1day5hrs uptime. Today I'm at 4 hours screen on time with 40prct left. I'm listening to soundcloud and played virtua tennis a bit. 9hrs uptime

Having jumped from a note2 to a s4 I can say the battery life sucks compared to it. Sucks badly imo.
On same usage from day to day the note2 would have 50 percent left at the end of the day. This one is barely holding on. And by that I mean moderate useage, push email, some gaming and Internet.

short answer: depends on what you use the most.
but,the galaxy s4 has great battery life lol... def better than my droid 3, i'll blow through that things 1500mah battery in less than a day easily, which moderate use lol

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).

Since i always post the same problem, battery life could be better, will probably get 8-9 hours, with 3-4 screen time. Gonna keep it stock kernal so its more stable.

i think 2800 mah battery not enough for daily usage

It's 2600 mAh, not 2800 mAh. And why do you think it won't be enough? They're probably making AMOLED even more efficient than it was last year and the new Exynos SoC is up to 30% more efficient than current offers because of the 14 nm half node.

They are slapping power user in the face with non removable battery. Now instead of carrying spare battery I need to bring a chunky PowerBank. Can't Samsung realize they are not apple and they abandon their core audience do them no good?

is it not possible to insert 3000 mAh battery to s6? it won't be more usefull for users? why samsung still parsimonious? s5 has 2800 mAh battery & s4 has 2600 mAh battery and s6 will come with 2600 mAh battery. sometimes i can't understand to Samsung.

Like I said, if these rumors get confirmed, it's quite possible that the GS6 will perform better than current smartphones, even with a smaller battery. Which in that case allows a slimmer, lighter device.
Enviado do meu Galaxy S5

If the phone is getting a QHD Screen I doubt that there will be any better battery results than the other mainstream smartphones.
Just compare the Note 3 vs Note 4.
What about a poll with:
a) I want a phone slim like a post card with 3-5 hours SOT
b) I want a phone slim like a S3/One/Lumia with 12-15 hours SOT

It seems like a non removable battery with 2600mAh
http://www.gsmarena.com/newscomm-11252.php

The QHD on the Korean S5 LTE-A had about the same battery life as the US variant. Therefore, the QHD on the S6 should have the same...if not better battery life even with a smaller 2600 battery. I wouldn't worry too much about...my only complaint is that it'll be non-removable

i see bro. thanks for your explanation. i think you will buy a GS6 when it available for users

Since S6 was said to use Exynos7420 instead of Qualcomm........the consumption of cortex A57 would exceed A15 and Krait a lot according to Anandtech

I'll take Option C. A phone that is 12mm thin and has more like 20 hours of SOT.
There's no point in making super powerful smartphones, if we can't use them like the pocket sized PCs that they have evolved into. I'm sure there are many people who would love to use their phone to get actual work done without having to worry about the battery. Also, since batteries wear out over time, I'd rather have a bigger battery than what would seem to be big enough at first.

Because the CPU/GPU only within the same generation range on 1080P(note3) and 2K(note4) though on paper spec. the latter one should be a lot better but still same generation and indeed that kind of power isn't enough to push 2K. Hence, the CPU/GPU will always require to run at a higher clock and battery draining even just on 2D.
S6 is running a whole new CPU with 14nm manufacturing process, the situation should be much better though but I agreed 1080P is enough on a tiny screen and I also prefer more battery life.

Is the battery removable?

I don't think so

The battery will NOT be 2600 for the MILLIONTH TIME. IT'S ANNOYING ME HOW blind all these websites and you lot are. The info is right in front of you the batteries were for G925 WHICH IS THE CODE FOR THE S EDGE. NOT S6
SO WHAT DOES THAT MEAN? S6 WILL BE MORE JUST LIKE WITH THE NOTE
NOTE 4 BATTERY 3220
NOTE EDGE BATTERY 3000
NOW STOP SAYING IT'LL BE 2600.

Its funny to see how rumors, leaks and teasers mess with people's brains and expectations, the media really knows how to get in your heads. We will know by sunday's time, then all of you will really have something solid to criticize until the next device comes up, so just hang in there. I just hope it lasts me the whole day on moderate use, so that I can charge it overnight

Butthurt much?

Battery size difference of 200 mah is meaningless. What matters is actual battery performance. Is there a correlation? Sure. Does every phone last same length of time with the same capacity battery? Hell, no.

Want to know the PROS and CONS of the Samsung Galaxy S8's battery

Hello everyone,
I want to know the PROS and CONS of the Samsung Galaxy S8's battery. I am currently a Samsung Galaxy S7 user and I am thinking to make an upgrade. I always wanted a phone to have a heavy battery life as I am a heavy user.
Also let me know if the phone charges faster compared to the S7.
Thanks in advance, it is my first time posting here

Hey Shajjadur,
Welcome to the XDA!
The Galaxy S8 charges quickly, not necessarily any faster than the Galaxy S7, but 15 minutes will give you circa 20% battery life, almost 50% in around 30 minutes and a full charge takes about 80 minutes. Wireless charging isn’t as quick, but it still charges far faster than an iPhone.
Here are pros and cons -
Pros: Better than it should be, fast wired and wireless charging, promises of long term safety and performance
Cons: Disappointing battery capacity, reduced resolution required for all day stamina, generationally a backwards step

S7 battery capacity after one year is 80% of new. S8 battery capacity after one year is 95% of new according to Samsung.

I got a killer mobile battery charger can do at least 5 full charges so never concerned anymore about battery life lol.
Example used my phone all day yesterday. Took pics used net etc and did small chargers now and then kept me alive all day and night.
Also it's fast charge too.
