Its not a fair test because of the large brightness difference which is even more apparent this new AMOLED screen on the S4. A fair test would be setting the phones to the same brightness. On the same colour.
[One (M7) General] Hunt3r.j2:
No, not really. The One in web browsing would likely be equal to the S4 if both are at max brightness.

We all know very well that Battery problem is one of the most common problem which is faced by many people around the world.There are many people who are facing some problem regarding a battery life.
[One (M7) General] hokoonho:
Seems that HTC found the key to save power. In the first release of One X, battery life is a big problem. But after 9 months, One X are more battery friendly and run 30% faster, and their One X+ battery life improved so much, someone said it's battery performance is as good as butterfly.

Recently, I visit the One X thread and looking for kernels, I found that kernel only with some minor config can give me 5+ hours YouTube HD Playback, 40% backlight.

With some better kernels, I have got 7+ hours YouTube or 10 hours XDA app browsing time, that's more than enough for most people.

But I will definitely buy a 64GB One since it has built-in amp, dual speaker and the camera. (Someone in China said the lens and sensor is from Canon, but they somehow don't want to release this info yet.)

[One (M7) General] jeffsanace:
Not so hard to believe, battery life on my EVO lte is drastically better than my wife's sg3. I can get 14 to 16 hrs on a daily basis and I'm a heavy user. And the 30% is referring to the sg3, I'm sure Samsung has also improved in the battery department for the upcoming sg4. All the most recent htc devices get pretty good battery life, so I have no reservations about this device taking it to the next level.

Bad Seed Customs

Just Sick!
[One (M7) General] JesseMT4G:
I am sold if it has 30% better battery life over my s3. I just did another update, so battery life is crap right now till the OS settles in, but once it settles in I get a good 12-16 hours give or take with about 2-4 hours on-screen time, a lot of streaming of netflix/pandora.

Hard to believe it would be that much better with the same usage, but I guess we shall see. I probably will be a guinea pig as I will have this sucker on release day in the States. Giving the s3 to my wife.

Hoping it is as solid as my MT4G was and not like my Amaze.

That would be a fair per protocol testing but for real world usage a simple browsing test with max brightness is more likely to report which device fares better for people who always use max brightness in any situation on their phones (and I know a lot of them).

[One (M7) General] debug77:
Here's my battery life so far. Picked the phone up Thursday and it's only had one charge really so far. To be fair, this is weekend usage (so not as much as weekdays!) but I've been taking photos with it, setting up apps etc...

Power saving mode is off, but it is set to switch data off after long periods, and use smart syncing "off peak" with the email.

Pleased so far but the real test will be when I get back into work next week and have my headphones on all day :cool:

[One (M7) General] Hunt3r.j2:
No, you just haven't looked close enough. Never run a display test app that shows you a pure blue screen because you will never un-see the burn-in again.
[One (M7) General] gaabrysz:
Hi guys.

Something is eating my battery. From looking at partial wakelocks I think it's audioout_4. I didn't play any music this morning so I don't know what is going on. Any help? I'm down to 85% in 1,5 h.
[One (M7) General] diggedy:
I've not bothered with any tests or anything I just know my one has the same apps and settings as my hox and it lasts longer than the hox. But battery life is all down to your apps, usage, auto sync settings, signal strength etc.

People get too hung up on trying to tweak the phone to get the ultimate battery life when really it's like pissing into the wind unless you do the exact same things in the exact same places every day :)
[One (M7) General] gaabrysz:
I know it's about apps an synch settings etc but yesterday was a different story. So I still want to investigate what's wrong.
[One (M7) General] Basil3:
Yeah, I forgot to take a screenshot, but according to the standard HTC battery stats, my phone was waking regularly through to 3am, then it stopped waking after the WiFi turned off.
[One (M7) General] epicfailguy2:
Close any game or app that uses the audio. Real racing was the culprit of that once.

Ran screen test on my 6 month old note 2. No burn in except on pure red green or blue theres a very very slight difference of luminosity that matches the status bar (which is pure black on my rom) whom pixels are a little brighter because they are off most of the time.
[One (M7) General] gaabrysz:
The thing is I don't play games. I do listen to some music and watch youtube but I did not today. Restarting the phone helped so now I'll watch for abnormalities when running apps.

Ok so after 2h and 37min since full charge and 27 min of screen on the battery is down to 69%.

App usage is about 83% like Kernel and android system (Gsam) and Betterbatterystats shows RILJ and Cachemanager as top partial wakelocks.
[One (M7) General] debug77:
Pretty sure it's more than an hour as I took the photo out, took photos etc.. at a party, and have been installing apps. Probably more than I'd do of a weekend with my phones usually, and this one lasts a LOT longer than they do.
[One (M7) General] ChrisDang:
In combination with the extremely slow charging speed (7hrs from 13% to 77%?), I've been very disappointed with the battery on my One. I haven't hardcore measured any stats yet but I can't seem to get through a full day of light/moderate use on this phone. I previously owned the One S, whose battery life I was very happy with--always made it through a full day even with moderate/heavy use. My light/moderate use consists of some texting, little to no calling, and a couple hrs of music a day (but always with headphones). Some web use like facebook and google searches are in there too. I also play Candy Crush maybe 30mins-ish to maybe an hr a day - this game isn't very graphics intense at all.

Is my phone battery just faulty (taking into consideration the charging time is so long) because I've been thinking of requesting a replacement? Should I be allowing the phone to go through a few more days of charging cycles to settle or something? My phone is only a couple days old.

I've downloaded GSam for now and will keep track of the battery life on the phone along with my usage.
[One (M7) General] Felnarion:
You have an app, or problem, that is burning through your battery.

It's software, not hardware. Do your diligence and investigate it thoroughly before returning it.
[One (M7) General] Neo-ST:
There's a number of reasons why your battery drains faster. Facebook app is a known hog, for example.

Also check out BatteryGuru app, after installing it I have pretty good battery life, from morning to evening of moderate use (calling, surfing, playing a game, using camera, etc.), I end up with 45% left.

Check this out: http://xdaforums.com/showthread.php?t=2279743

Use a bit of common sense, look for apps that sync in background and please don't compare battery life of One and One S, it's like buying a Ferrari and whining about fuel consumption :)
[One (M7) General] TheGaslight:
I'm in the same boat as you, really struggling to make it through 8 hours of work with light usage. My screen on time was 1hr 10 mins and Wakelocks of about 45 mins and I was left with 12% after 8 hours! I get in from work and have to put it straight on charge. If I'm browsing the internet the battery goes down roughly 1% per minute. If I play any games it drops dramatically in little to no time. I've disabled all synching including Facebook, Google Now, and have emails check every hour. I'm wondering if a hard reset might do the trick?
[One (M7) General] danton47:
Do you use the phone while charging? If no, then 7 hours to charge from 13 to 77 is definitely not normal. It takes 3.5 hours to charge my htc1 from 1% to 100%
[One (M7) General] ChrisDang:
I'm not using any apps (at least none that aren't native to the One) that I haven't used on my One S. All my apps are on the same settings. It may very well be simply a faulty battery on my particular phone, but yes, I am hoping it is a software problem so I won't have to go through the trouble of getting a replacement. I also feel like I don't want to have to use all these sleep/wakelock/rooted applications as I should be able to get decent battery life without all that.

I agree that comparing two phones isn't always the best idea. But the One S also had a smaller battery and impressive specs (for its generation at least) itself so I thought it would be a decent comparison.

I don't use facebook too much actually, and usually close tasks when I'm done with them. I saw that thread and followed many of them - but I'll check it out again. Thanks.

Did you download anything different? I've only downloaded maybe 5 or so extremely popular apps that I don't think would have any strange problems. I'm actually not even sure what wakelocks are but I've seen the term thrown around this thread so much.

While charging, I maybe use it 30mins moderately (web browsing, short videos, texting) but otherwise no. Yeah the charge from the day before yesterday was also bad, maybe 8-9hrs and it went from 0%-84%. This was using a different outlet and charger too.
[One (M7) General] Neo-ST:
OS version? Maybe you should try factory reset, just make sure to backup everything...
[One (M7) General] TheGaslight:
I've downloaded a bunch of apps, mainly news and sports apps with a couple of games. I have a battery percentage icon in my status bar and AnTek quick settings. Anybody know if either of those are a known battery drain?

[One (M7) General] Neo-ST:
Hmm I just remembered something.

A while ago I had a wakelock of media server, which was caused by faulty MP3s (they could play but had errors in their headers, which caused media server to constantly try to read them).

Connect your One to PC as mass storage, download MP3 checker program (it's free) and scan your MP3s. See if it finds any faulty ones, then delete them.

If you can, sure why not delete everything :) It won't do any harm but you ruled out one of the possible solutions...

This is related just to Google Now widget, if he's not using it then there's no problem...
[One (M7) General] TheGaslight:

Necessary to calibrate?

There is a post in the battery saving tips thread suggesting that we should do this:

1) do a hard reset at 100% ( green LED) ,

2) when phone restarts charge till (green LED) again,

3) Do another hard reset

4) fully charge to 100% (green LED)

5) drain the phone to 2% remaining

6) fully charge to 100%

Is this really necessary? I thought we were past the days of finicky battery calibration methods, and all we had to do was a mere flat to 100% charge...
[One (M7) General] NxNW:
The thread you are referring to has been pretty silly overall. There's a lot of superstition going on there. The specific steps you are talking about will not make your situation better unless you *believe* that following them has value. In that case it will in fact make you happier. But your battery is not going to perform better in any meaningful way.

There are some good general ideas out there: read batteryuniversity.com, avoid high temperatures, don't try to charge it from 0% to 100% in less than an hour, avoid spending a long time charging at 100%, avoid spending a long time at 0% charge, stuff that is basic to any lithium ion or lithium polymer battery. With replaceable batteries you could say, meh, just get a new battery if your old one starts to lose it. But with non-replaceable batteries, these factors start to matter over the usable life of the phone (even if you consider the phone's usable life to be only two years). So it's good to have at least a passing familiarity with these concepts.

But once you've educated yourself about some of the obvious no-no's, just use your phone. Specifically, the "procedure" you quoted sounds like pure 'magical thinking' to me. In fact, because it involves a deep discharge, it's something I would actually avoid.
[One (M7) General] ECEXCURSION:
Yeah, we are past that point. People need to realize that both the kernel and battery need to settle in for peak performance and battery life. The software is smart, don't try to outsmart it (tm).

[One (M7) General] thegregulator:
This is on Android Revoluion 10.0. Mostly Wi-Fi at home. When the screen was on I was using XDA, Twitter, Facebook, YouTube, and some web browsing. I also played a fair amount of words with friends. The screen was set to auto brightness for most of the day (about 12 hours). I also have two email accounts pushing emails, and auto sync on everything else and Google Now is on. I did Greenify Facebook and other services that I don't need notifications right away (facebook emails me when I get a notification). Pretty pleased with the results.

Edit: forgot to add power saver came on at 14%. It was off all day.
[One (M7) General] Xerro-Five:
Here's my best time without using power saver (note that it comes on at 14% automatically). Everything stock. Not bad IMO. But it seems like the combination of bigger battery, dimmer screen, and maybe (? sorry I'm just going on logic here...) more efficient backlight tech gives your S4 more life. I'm sure the CPU design helps too if it does what they say it does :)

http://xdaforums.com/attachment.php?attachmentid=2128587&stc=1&d=1374260828

I don't agree with others that this is a pointless test because I'm one of those people who uses all my devices at full brightness all the time, especially when the screens are very good like the One or my iPad 3/ipod touch 5. Just seems like a waste to not take advantage the amazing quality and use outside benefits greatly of course too. So for me this is a very relevant test because its showing you the best the phone is capable of. Just because there are positives and negatives to each phone doesn't mean you can't compare them ;)
