Battery life is GREAT, until you use it?!

This is not another thread about battery life obsession. It's more about a curiosity.
I have my Evo tuned so that it has great battery life on standby. When I use it for anything--SMS, data, local apps--the battery drains very fast.
I know that data, CPU, and display are the major consumers, but...
I have a Nexus One, with also a 1Ghz Snapdragon, and almost exactly the same loaded apps. Same screen resolution, both on 2.2. Both have 1500mAh battery. The only difference is the display technology and radio (GSM/EDGE/HSPA vs. CDMA/1xRTT/EVDO).
When used equally, the N1's battery does not drain nearly as fast as the Evo. How come? I know AMOLED is supposed be more power efficient, but by that much? I know CDMA can be less efficient, but again, by that much?
- - -
Duh! Edited from Hummingbird to Snapdragon (got confused-I just picked up an Epic which has Hummingbird). Thanks for correcting.

They both use Snapdragon, Hummingbird is Samsungs CPU codename, it's based on the same architecture but uses a smaller process.
What software are you running?

Same exact problem as OP...this baffles me.

Is it something new, or has this always been happening?
Was it after the new update or kernel WHATEVER, that you flashed?

If you’re running the stock kernel, do you think the fact that the screen is physically bigger may have something to do with the difference? I’ve always accounted the difference in the battery drain speed (between screen on and screen off) to the fact that most of us are running tweaked kernels that are overclocked when the screen on (with 5 point multi-touch, etc), and underclocked with the screen off.

The problem with battery life issues is that most of the time it can be just a perception and not scientific evidence at all.
Personally, I had an iPhone 3GS prior to getting an EVO and I would say the same exact thing happened with my iPhone. Especially when I was playing games. It doesn't seem to happen with my EVO.
Even seemingly silly things like the Battery Icon can help with the perception that battery life on the phone is bad. Since it only has 4 levels, it kind of tricks your mind into thinking your battery is draining really fast. Try flashing this.
Scientifically, The difference in battery life running the same exact apps under the same exact conditions would be almost negligible between an Evo and a Nexus one. You could even test them side by side and see for yourself.
Also, some facts:
- CDMA 3G is LESS power hungry than HSDPA when actually using it. Heck, EV-DO even uses less power than CDMA 2G(1xRTT)! Wi-Fi uses even less, so use it whenever you can.
- There's a huge misconception that AMOLED Screens use a lot less battery than regular LCDs, but in fact, that's only when the screen is showing LOTS of black color. During a web browser session with lots of white webpage viewing, AMOLED has no Power consumption advantage over LCD.

Signal is a HUGE contributor. I get about 12 hours out of my battery 3-4 out of 5 bars. I went to the sand dunes and had 5 bars and my phone lasted 28 hours.

there are some variables here - my router at home sucks, so I actually get better signal (and battery) with 3g and not wifi unless I'm in the same room as the router. Like the guy above me said, signal plays a huge part in it.

When I run Handcent, N1 uses about 20% less battery over ~400 messages. Browsing sees similar results. No exotic apps and I keep close eye of what is running/syncing in the background.

On both phones, I have a % battery gauge. I use both phones in good coverage area and have observed them over weeks of use. I would use one phone for the day, do the exact same thing, use the other phone the next, and consistently see the N1 having 20-30% more battery at the end of the day. I'm thinking of loading "current widget" to see the drain rate between the two phones.
On the subject of radios: I have seen manufatures list longer battery life for EDGE vs. HSPA and the same for 1x over EVDO. Also I [think] usually see longer standby times for a comparable GSM/UTMS phone over CDMA (e.g., Touch Pro2 on GSM/UMTS vs. Touch Pro2 on CDMA).
When one says that EV is less power hungry than 1x, are we talking about a time-use comparison or efficiency? Example: 1Mb download, 1x takes, say, 1 minute, while EV takes 10 seconds. Yes, for that download, EV took less power. But if one were to have 1x & EV both running for one minute, which takes more power? I ask because I remember seeing EV transmitting at higher power than 1x.

Is this really a thread. You use your phone nonstop and wonder why your battery lasts the way it does. You cant compare a psp to a nexus s. Close this thread. You want better battery life stop hogging the phone.

My battery lasts me all day. I play n64oid for an hour a day during lunch at work. That drains 15% to 20% during that time. So yeah, that sounds normal.
Its not a console, built only for games. It has other things running all the time. Also, my old PSP maybe got 5 hours, you must have an extended battery.
Sent from my Nexus S using XDA Premium App

yes this is normal
i can burn through the 100% charged battery in 3~4 hours just browsing the internet alone
the WiFi or 3G is what eats all the power, same goes for the SAMOLED
other devices last even less time, using HTC Desire and similar devices i can drain the battery in 2~3 hours
i always carry extra battery packs with me, i'm a heavy duty user
So, to your answer, no, it is not unusual
High end 3D games also uses a lot of power in the CPU, GPU, SAMOLED and if you are playing online like WOW online for Android, then it will go up even faster.

[Q] Battery life, compared to the Galaxy S
Hi guys,
I used to have a Galaxy S device, and recently purchased a Nexus S, and gave the Galaxy S to my wife.
I assumed that, given the fact that these two devices have a very similar hardware, the battery life would be somewhat similar in both.
However, this is not what I have experienced at all. I basically reinstalled all my apps and home configuration in the Nexus S. The only difference being that I'm using a darker wallpaper now (which is supposed to improve battery life.) The rest is pretty much identical - I basically restored all data from my apps using Titanium Backup (not the system data, evidently.)
I have noticed however that the Nexus S spends a lot more battery than my Galaxy S, especially when the phone is idle. I have everything turned off (GPS, NFC, 3G and Wi-Fi) just as I did with the other phone. Even on Airplane Mode the Nexus S seems to use a lot more battery. Leaving the phone on Airplane Mode at night would barely consume any battery at all with the Galaxy S. The Nexus S does take some hit though.
The battery life is still not a bad one. Especially when compared to LCD phones. However, the Galaxy S is significantly better with stock 2.2.
My question is: Why could this be? Is it because of Gingerbread? Or am I missing something?
Thanks guys!

it's quite the opposite for me
my previous phone was a SGS and it chewed more battery than the SNS

Try to deactivate the GPS and Wifi if you do not use them. You can also use some apps to deactivate 3G access.
I wish Samsung produced higher capacity batteires though.

Was your SGS on 2.1?
I did notice that on Froyo (2.2) the SGS had a much better battery life than on Eclair (2.1). It really made a great difference.
But my SGS on Froyo is consuming a lot less battery than the SNS on 2.3. Especially when the phone is idle (both with everything turned off and set to GSM or even on Air Plane Mode).
So I was wondering if this could be a software issue.

Same with me. I came from a Vibrant, and no matter what ROM I used, I'd lose around 8-15% of battery while sleeping.
With the same settings, and apps now on the Nexus, I lose 1-2 percent while I'm sleeping.
The idle is a lot better for me with the Nexus, and I lose a little bit less while I'm actually using the phone as well.

For me it's exactly the other way around. I assume your Vibrant was on 2.1, right? Cause in 2.2 the SGS does much better. And this is what I would lose: 1-2 percent when on airplane mode for an entire night.
Mind sharing what your config is? I'm on 2.3.3 + Netarchy 1.2.7

I was on 2.2 on the Vibrant. I was mainly using the Axura and Trigger roms.

Go get it exchanged and if it keeps happening, then it's your usage that you need to deal with by getting more batteries or keep it on the charger whenever you can.

I read a lot of threads and posts about battey life on NS and the problems of 100% charging, and most of people declared that the NS has a better battery life of all i9000 series or S series.
Maybe a nokia would suit better, days of battery

So wait - your PSP has both an extended battery and an extended external battery and you're surprised it lasts longer?
The Nexus S has a 1500 mAh battery in it. The PSP extended is a good 3600 mAh, and external packs can be 4200 or more. So that's 1500mAh for the phone and 7800 for the PSP. The PSP has 5.2x as much battery to power it, so it's logical that it'd last longer.
The phone's also a lot smaller and running power hungry radios for network connectivity, an OS to manage everything and misc. background tasks in addition to whatever game is running.

You're brave saying this in this thread. Most of us now thing you're an idiot...
My Nexus S went 33 hours before last charge. I am a light user though.
To check how you're does, don't use it for at least an hour one time, coming off charge. You should only lose 2-4%. Then check battery usage and see what's taking power when the phone should be doing very little.

[Q] battery life comparison exynos vs snapdragon?

Are there any comparisons of the two cpus available on the s4 when it comes to battery life? Thats the only reason for me to try to get an exynos version if its shows to be better in that respect.

Yeah, that's a good question I want to know the answer too, there are many people having testing devices but they are too hungry about testing the damn processor and gpu instead testing properly the battery life. -_-

With wich cpu? Also no comparison to the other version mentioned here.

I'm not convinced, even with S3 you can spend all the battery juice in 3 hours if you want. To do a proper test you need to leave the device doing the same job like an Snapdragon S4 during the same time.

Thaty what one hears, yes.
However I would like some actual test reports - for instance how long does the phone last for web browsing, for video playback and on standby?
I would like to see actual numbers.
As for the screen:
It is said to use 25% less power compared to previous amoled display generations. However that 25% value is something we have to trust samsung on I think, at least I have not seen any actual tests on power consuption of the display alone and it's probably not easy to test.
The way they have managed the display to consume less power is to use use phosphorescent instead of fluorescent green diodes, which use way less power. Until now they could not produce the green ones with an acceptable lifetime. The red ones have already been phosphorescent, and the blue one are still fluorescent since they are hardest to produce.

This. This so many times over.
So many people are parroting the "Exynos will have better battery life" thing but this really remains to be seen.
If the better battery life is in exchange for crippled A7 performance at inconvenient moments then it's useless. If better battery life isn't available for when you're using intensive apps then it's also useless.

The One has the best standby battery life of any phone EVER.

I swear this thing does nothing when on standby. Screen on time is at just over two hours and yet the stats are amazing. Interestingly I'm on my third one, the other two were NOTHING like this.

Couldn't agree more... I am only on the first "One" . But battery life is fantastic compared to my S3. My current stats are showing 54% remaining after 26:25 hours. Estimated remaining time is 33 hours. That's with a little bit of 4G usage and 30 minutes talk time. Total screen time is showing at 1.03 hours.
By this time of the day, with similar usage, by S3 was sitting under 50% and would remain for another 6 hours. I was originally very worried about the non-removable battery, but with performance like this I am no longer worried!

Best standby I have ever seen on a phone is the iphone5 to be honest. But the One definitely isn't far behind.

For me coming from an iPhone 5 and before that iPhone 4 and before that numerous other phones..this HTC one has been the best for battery life by far. I'm averaging battery life of 17 hours according to gsam battery app... I never would have imagined getting battery life like that and I am not on power saving mode. And as for the note 2. I would hope it bas better battery...it's not that much bigger (screen) and it has a 3100mah battery compared to 2300 in the one.

I'm lucky to get 8 hours. I'm not impressed at all. I had to charge it twice just to able to do some photography.
My recent past phones were an iPhone 5, galaxy s3, and note 2. Only the 5 had worse battery.
I have undervolted, have lte off and It drains fast when the screen is on. Who cares about standby. How does it actually last with use.

the battery has been very inconsistent for me ever since i got the phone a few weeks ago. sometimes i can go the entire day just fine and other times i need to charge by 6 pm. it definitely wouldnt last an extra day if i forgot to charge it before going to bed.

I don't have any hard evidence but this phone kills my Sensation. I would use about 1 hours of actual usage in a day while the rest of the time is in standby with wifi, and I can get through my 8 hour day with about 60% to 70% left. My sensation would have been near 20%, and I have to charge it if I use it more often. I am really impressed.

No idea why you are here, bashing the One. HTC has had a bad reputation for notorious battery life, but the One is clearly solid in this aspect.

Erm yup that seems more fair. I also didn't claim One has the best battery life. I mean the term "best" is entirely arbitrary. The best battery life on an android would definitely be the Razr Maxx. It'd probably handle close to twice the standby times on the S4.
So in that case why are you so eager to prove that the S4 is better than the One? I mean if you really feel it's better go ahead and buy one. Point proven.
For me and the other One users here we are VERY satisfied with our battery life, thank you very much.

U lost 20-25% overnight? U clearly don't understand the basics of wakelocks. Nuff said.
I have the S3 as well as the One and my S3 and my One have approx similar screen on times but the S3 has longer total up-times with similar screen on time. With the H1, u need power saving on ALL the time to get decent battery life.
The S4 will eat up this phone in terms of battery life.

honestly, if they just put a 4000mAh in it, I wouldn't mind if it weren't replaceable. And I seriously doubt with the kind of perfomance/specs its gonna have, anyone would really mind the extra thickness either. Not to mention heft (cough, durability).

It's not how big the tank K is but how much less is sippped from the tank
Nexus 5 so battery is 75% if G2
But battery life on nexus 5 is far less than 75 percentage of G2 albeit having a smaller screen

Don't forget - with a removable battery, I'll bet some vendor will come out with a 3500+ mAh battery...

true, tho hopefully LG itself does it, kinda like Samsung did with S3, which I have.

more than six hours of screen-on time with 100% brightness, it's really impressive.

it looks promising but i would take this article with a grain of salt. I want to see a article or a video with alot of apps and features turned on this reviewed. i believe that would be a real battery review

Still, LG hasn't outed official talk, standby, browsing and video playback times yet, so we can only guesstimate the battery life of the G3 to be pretty good, based on some tangential proof from improvised battery tests that are popping up.
First off, a prototype version of the phone has been put through its paces, and the phone lasted six and a half hours of video playback on a charge, as you can see from the screens on the right. That might seem average, but the test has been done at the screen's*maximumbrightness, which*LG officially pegs at 430 nits, instead of the usual 150 or 200 nits, so the result from standardized routines like our own battery test, are likely to be much higher.*
Also so the test was at basically 2× brightness of a normal screen. ... so at lower brightness it should do very well

Thanks to the removable battery I couldn't care less about battery life you can always take one or even two with you and go through half a week without ever needing to charge your phone good job LG :good:
I'm sure it will feature some sort of ultra power saving mode just like the S5

Is it really nice to always have a secondary batt and most time having to turn off phone then replace. I quite don't like that and I don't see that very cute at all. Maybe it's how I feel but that for me just seems not right.

I would totally have taken a 3500mAh stuck battery like in G2(not impossible to remove after some years) instead of 3000mAh removable.

How about we first get the phone and test it ourselves?

I never said 3000mAh isnt enough, but 3500mAh would last longer and most people dont run around with an extra battery in their pocket even if they can. Saving 1-2 hours of work to replace a battery like in the G2 after 1-3 years isnt really that much.

Just the same way you are thinking, don't you think that LG thought of that?

Of course they did, but they are catering to the people who are stuck in the old days when smartphones didnt last as long and batteries died much faster. Sure batteries degrade still, but if they hold longer between the charges and with more improvment it would be years between needing to change it. LG did the right thing with G2, but people arent smart enough to see it, so LG had to go back to the old ways to win the heart of the stuck.

Okay, what I'm saying is if they have thought then it'll make no sense for that regard. If so, then the 3000mAh batt along with their Optimization makes it enough to have that battery.
Like for example, there are different desktop power supplies but some of them are different quality. A 3 star 1200w quality desktop supply could be equivalent to a 5 star 800w quality supply.
