Does LTE really drain battery that much?

I will leave my phone alone for about two hours and when I check back there will be 25% battery gone. Is this normal? Should I report back after I've used the phone for a week or so? I just got the phone this weekend.

Lte does drain battery very fast but I don't think that is normal. Are you in an area of poor coverage? You could also have a wake lock. You can check for wake locks with better battery stats.

LTE will only drain battery during use so that isn't your problem.

Ah I see. Well, my phone died before my work shift was even over. It must be whatever the wake lock thing is. Once I get this resolved I'll love this phone!

Better Battery Stats will help you pin point the wake lock. Post screen shots of this app if you don't understand how to read it.

Will do. So far after a full recharge after my battery was dead I had it just sitting on my desk for about 40 minutes and it was still at 99%. I'll leave it uncharged while I sleep and see how it is doing in the morning and I'll post the stats.

Hmmm, it seems that from overnight (About 7 hours) it has drained about 9%. Is this normal? I'll see how it does through work today and I'll report back tonight. It doesn't seem to be draining as much as it did before.

Oh yeah. Your good. 1% per hour idle is what you should hope for. But I wouldnt make a ruckus about 2% extra

Seems I overlooked calibrating the battery with a power run out since it is a new phone. It seems me letting it run down fixed my problem. Its been about 3 hours and I'm only down about 4%. I'll still monitor it every 2 hours or so and post the results at night.

Yup...that's totally normal for a healthy stock battery without any major mods or tweaks.
That's about 1.29% per hour.
If you want to get that number down closer to .5% per hour, try an app called Green Power. You can set it to turn off wifi/data when your screen is off. You can tell it to wait say 30secs before it does this.
Then you can tell it to enable wifi/data at "screen on" or at "screen unlock".
If you don't use push mail etc., this is a good option to keep your battery drain minimal in standby. You can also choose this behavior for night time only. And...you can choose apps to go into the "exceptions" list...a a whole bunch more fine tuning.

[Q] Battery Drain Over Night

When I had my Note 1, for some reason over night it would drain like 50% of the battery, no idea why so I sold it. When I has my iPhone the most it ever drained over night was about 5%, 4 and 5. Last night my Note 2 drained about 12%, the only App open was the Alarm.
I know 12% isn't anything major, but with the problems I had with the Note 1 I just don't want to wake up have been fully charged the night before and then have to charge in order to even use it the next day. I need an alarm set or I won't wake up to go to work.
What is the best way to keep battery life over night but still have an alarm set?

Install betterbatterystats from playstore to keep a check on Battery hogging useless apps.
YOu dont need to keep the Alarm open in the background exclusively. When you set an alarm,it would be there untill you disable it manually.
12% overnight is a bit more than normal. For a 6-7 hours, battery drain should not be more than 5-6% when the screen is off and phone goes into Deep Sleep mode.

Why not just charge it over night so that you always wake up with 100% :S

Cause the charge cable is short and doesn't reach to a sensible spot for me to be able to quickly turn the alarm off before it wakes the rest of the house up!
I'll do a few more test runs before I install any battery apps, from what I have seen so far most apps actually mess up the battery for me. That Battery Widget Reborn on my Nexus 7 takes the charge time from about 2-3 hours to 7-8. And one's I've used in the past actually drain it quicker.

Woah...never experienced that mate..did you turn off wifi?? For me 5 hours of sleep will only decrease 1 -2 %... stock rom dll7... check your apps in the background

A TRIANGLE AWAY will make your WARRANTY stay
Hit thanks if you love your phone =)

Ah that's a fair reason
I left mine off charge over night so I could compare. I left everything on as per my usual day (WiFi, GPS, auto sync) and had an alarm set.
I lost about 12% as well

Betterbatterystats is not an "battery" app. Is an app the monitors your phone and reports misbehaving apps or partial and kernel wakelocks.
It has nothing to do with increasing battery charge time.
Search it.

May have to give it a go if the problem persists, but for 10% battery it's not major. But thanks for clearing that up!

The only thing that you need to do is turn off data connections and wifi. This way I lose 1-2% battery life over night.

Well Android's ecosystem is made in this way. Literally you can't do anything. If an app or a couple of apps think that they need to run at a certain time, then they WILL run, it's as simple as that. No app is there to stop it, but yes some apps are there to make it worse, so stay away from them. One night you will notice 5% drain, the other night 10%, with same exact settings.
Still try to turn off Data/3G at night, if you don't need it. And get used with it

Abnormal Battery Drain ?

So every night before sleeping I turn Data/ Wifi off, Past few nights ive noticed there has been a 12-15% drain in 8-9 hours.
Battery before sleeping 30%(data/wifi off)
Battery 9 hours later 15%
Stock 4.2.2
No Intense Background apps.
Is this normal ?? I don't think 4.1.1 had such battery drain with screen off and no data/wifi.
Thanks,

so u basically(roughly ) have 1% drop an hour? thats pretty damn good if you ask me
mine is usually 10 hours with intense use and 30 hours with minimal use eg: at work

That's normal at around 30% battery left. Once it reaches 30 and below it really would drain that much even without doing anything. But if you start with 95% percent and overnight drain of 15% with all off, then there is a problem somewhere. I usually have overnight drain of 3% for 8 hours.

Thanks for the reply buddy, 1.5% an hour seems higher, but as mrm43 said i think its the cause.

Thanks for your reply, I had a feeling about what you just said. But I don't recall this happening before, I could be wrong. Will charge up and test tonight and post results.
Also, I'm noticing my phone getting warm past 1 week while normal usage( Web surfin+music) area behind the camera.

So just to post back, I charged the phone upto 85% and turned off Data and Wifi, Woke up 8 and half hours later and the battery was 79%. Which is ok I guess, assuming only cell radio was on.

S3 Battery Drain

Hi, I had my galaxy S3 from Rogers for almost 1 year and the battery drains like crazy!! When I first got the phone the battery life was ok. It lasted 1 full day (with the settings auto brightness, wifi usually on [when not in wifi area, using LTE], vibrate only, power saving on and snyc on. I turned off gps, bluetooth, location services, and motion). About 6 months ago I dropped the phone in water :S and I got it repaired. The phone battery life was still about 1 full day (with the same setting as above except when I'm not in a wifi area I use 4G to save battery life). After that every month the battery life seems to get worse from 1 full day to about half a day :S. After doing alittle research (this was around May/June) I found out Facebook was killing my battery so I stop using it on my phone then my battery got better (to about 3/4 of a day). But after that in July and August the battery life got really really bad, it will probably only last 5-6hrs. I honestly don't know what is wrong with it now. Is the water damage the problem with my battery drainage?
I'm running 4.1.2, never rooted and I'm running Nova launcher too.

Get better battery stats or gsam battery monitor to rule out a rogue app(s) first...

Maybe the battery cells are dying out?

I leave mine on auto brightness too, I still get around 24 hours on a charge, and between 5 and 6 hours of screen on time. My phone is only about 3½ months old though... Could be the battery??

Is it the original charger that came with the phone? And are u charging it from the wall or pc??

Ya I am using the original charger and original cable.. using ac supply, with plugged in wall...
The thing is if I reset my device ( which I have done 2-3 times) and after that, watching video/playing games/ internet surfing etc. With the charger plugged in, works fine... I mean it charges my phone battery fine. Battery is new. Checked its condition with battery monitor pro... it states its good.
But after a couple of months after resetting, I face the problem of slow charging, with my phone in use while plugged in... did a lot of search but didnt help out. Cleared dalvik and other cache.... nothing seems to be working.

[Q] How is your standby time battery life?

I went to sleep with 100% and woke up with 93%. I left WiFi on, I'm sure that if I turned it off it would improve but I was curious how it would hold up.
Wondering if anyone has tips for improving standby time battery life.

Are you seriously thinking that 7% while you slept overnight is some kind of problem?

Arround 1-2% overnight(wifi on, but with "Keep wi-fi on during sleep" on Never)

Yes.
I can compare that to iPad mini and Windows Phone ( Nokia N925 and N520). 1-2 % with GMS/LTE on.

Same Here
Yes I am also facing the same problem. Terrible battery time. I charged my Tablet yesterday and pulled it out at 100% at 10pm. I put it on Airplane mode and went to sleep. When I woke up today at 6am the battery was showing 70%. It ate 30% at night doing what? I am very disappointed. On Kitkat 4.4.4 I never had such terrible battery performance.

Same here, on a fresh Lollipop install, wifi turned off during sleep, bluetooth always on, and with only a few apps downloaded. Last night I unplugged my tablet and it was still 100% this morning. Been like this since I flashed stock Lollipop after a full wipe.
On 4.4.4 with a lot more downloaded apps I was getting abysmal standby time. The confounding thing was, power use during standby would be fine for a couple days, then turn all to heck, like to 20% plus per night, wifi would turn on by itself during standby and stay on. When I cleared the caches it would go back to being OK for a couple days, then turn bad again. I had even turned off automatic syncing on every app that I was able to do so.
Couldn't figure out which app(s) were the culprit for the life of me. So now I am adding new potentially problematic app back on at a time to see if I can figure it out.

Here is what happened today. Turned off charging at 100% at 10:45pm and woke up at 9 am to 70% on airplane mode. Please tell me that others are facing the same problem!

That does seem pretty weird. This is my N7 since yesterday morning:

Thats not bad at all. I dont know why mine is doing this. What do you guys suggest i do?

I was on jellybean before lollipop and it had waaaayyy better battery life
