Battery life of Evo4g LTE 2x that of S3

Im coming from a 14day trial period with the evo 4g lte to the S3 and love both phones. they are both great. I like the S3 as a phone just a little bit better but I miss my evo 4g lte purely because I got twice as good battery life then my s3. How is it the evo dominates the s3 in this regaurd. Both devices are/were rooted with good battery saving roms. I can get a full day of medium/light usage without charging the s3. But I could get 2 days easily with medium to light usage. What gives?

You are confused.
First of all, your screenshot is useless - you don't show the actual graph, screen on time, nor voice calls.
Second of all, I own both phones at the same time. SGS3 is somewhat better at battery life than evo lte. Either 1) your sgs3 battery is defective, or 2) you haven't used sgs3 enough to allow calibration of voltage to battery capacity, or 3) your signal strength is not the same as with evo lte - lower signal strength = more battery consumption.

With light usage I got over 14 hours of battery usage and 90% battery strength left. With the bad signal reception at times I get 14 hours and 65%, which tells me it also depends on reception. Now let me just say that bar fro bar -dbm for -dbm my SG III is on par with my Photon in weak signal and strong signal reception every where that I have been. I still have my Photon comparing signal strenth bars, and -dbm for signal reception, and hands down they are very close -dbm and signal wise. I usually dont see more than 2-3 difference in -dbm.

I returned the evo lte for the s3 days ago and I couldn't be happier. I was getting great battery life with the evo but then I realized that it was because I didn't like the phone and all I did was make phone calls and send texts. The S3 is doing great for me considering that I don't put it down for more than a few minutes

Here's my battery life:
usage - playing youtube hd videos over wifi

OP, get an extra battery. Problem solved.

I do get really ****ty service in my apartment. I turn my mobile network off altogether and use wifi at home. My phone always going in and out of roaming. That I'm sure isn't helping. I have an air rave on its way. Hopefully that helps

How on earth do you guys get so much screen time from your battery? My battery will last me all day and through the night, but me screen time will only be slightly longer than 2 hours.... What am I doing wrong??

An airave will definately help. You'll have full bars in your place (only annoyance is it will drop your call if you leave the house when your phone drops off the airave). Might want to make sure you limit the connections if you live in an apartment though, otherwise everyone else with a sprint phone will connect to your airave.

I wonder if using wifi calling, which I believe shuts down the cell radio, would save power? Also, who is using power saving regularly?

Actually anyone can do wifi calling if they have a Google voice number. It's just that T-Mobile has it built in and doesn't require Google voice. An app named Groove IP is great for this. However I don't think it would make much of a difference in battery life over a regular call.

keep in mind guys, the forums are combined. GSM users are almost always going to have better battery life than their cdma counterparts.

Yeah but you cant swap in backup batteries on the eve lte . backup battery usage negates all battery usage issues.

Truth but like you said only T-Mobile has it out of the box.I have use groove IP in the past and is not too bad actually.good thing about my plan is the T-Mobile wifi calling is free minutes even if I'm outside the us.is not perfect but it works fair enough

I would make sure that the s3 is set to cdma only and not cdma/lte. Having the lte on when there is no lte network drains your battery quicker.

S4 Charges fast and Discharges fast

Hello,
My S4 is nearly a week old now, it's the international GT-I9500 octa-core version. Since it dons a big battery of 2,600 mAH (middle point of S3 and Note 2) it was suppose to last long more even with heavy usage.
My usage is moderate, a few calls, but I use connectivity extensively i.e. WiFi indoors and Mobile Data outdoors.
I tried switching off the WiFi to preserve battery and to see any boost but zilch.
Whenever I put the phone on charge, it charges very quickly and when the charging is complete and I remove the phone from the charger, it discharges pretty quickly, goes to 99% in a minute WITHOUT any usage.
What could be the issue? I even formatted my memory card from S4 as I read some bad mp3 files or something can cause the battery drain and such.
Everything is stock, both ROM and Kernel and the phone is not rooted atm
I'm attaching the screenshots for my cycle with minimal WiFi and Data usage.

I can get more than 16hours on my S2 easily with average usage...This is just BS optimization from Samsung...

It's better than the s3 because the battery is larger but I'm telling you that screen is a hog. It's larger and brighter and its 1080p; yes the resolution causes the gpu to eat more battery too.

im wondering if there's a way to switch the screen to 720 mode instead of 1080p to save battery life. similar to switching a computer monitor so you stress the gpu less during a game... this would also save a small percentage of battery life...
also a more efficient auto-brightness would be great.

Same here, hate watching the battery drop so soon. For me, what I've observed is that WiFi eats a lot of battery than mobile DATA for this set when it should be the other way around...
I have my internet disconnected at home due to some upgrading of the lines in my area so I haven't been using WiFi at home, only at office, so mobile DATA was switched on all day yesterday at home and when I go outside and surprisingly the battery didn't drain a lot.
I'll post screenshots of this cycle as soon as the battery drains down to 2%

No! Mobile data is one of the biggest battery killers going! I have my toggle within the first 5 so I can turn it on and off when I need it easily
Sent from my GT-I9505 using xda premium

With big screen and higher resolution, it will definitely consume more power. try to turn off screen and kill running apps when not needed.

16hours on battery is quite good considering the WIFI indoor and Data on.
i probably get a little bit more than that but less wifi usage and data is only EDGE in my country.

Nothing alarming
Firstly, your stats are perfectly normal. I got the same results on my stock octa core version.
Try omega its much better battery consumption wise. Other tips: Switch to 2g only if you are using your phone just for chatting, keep backups off and turn unnecessary sync off. Turn off your screen tap sounds.
You might already know all this.
Anyhow, trust me 16hours at 60% is not bad. Hopefully samsung will do something about it with future updates.
CHEERS.
Ow and if you are over with your honeymoon with all the air motion gestures smart eye tracking features, turn them off if you want to save some more.

So I have had my S5 for a week now and my batt life is aweful. Yet I hear everyone saying its awesome...
Here is my setup. Nova Launcher, Wifi always on, but disable scanning and set it to only keep on while sleep if plugged in. Bluetooth always on, I use it 3 hours a day. So need it....
GPS always on, High accuracy...
Brightness in the middle and set to auto.

There's something wrong with the camera on these phones. After I open up the camera or snapchat, my battery drains fast. The phone doesn't go into deep sleep after closing camera apps. I restart my phone multiple times per day, but my battery drains at 2-4%/hrs with a couple hours screen on per day.

Last 100-8% took 40 hours with almost 5 hours screen time. Neither power save modes were on. I had WiFi 70% of the time, with a decent 4G signal otherwise. This is 2-3 times what I get if I use my camera without restarting my phone.

I have a similar set up as you. I keep BT always on and GPS always on w/ high accuracy, turning BT off doesn't do much to the battery life imo.
The absolutely biggest difference for me was to go into location settings and hit Google Location Reporting and turn off location reporting and history. Also turn off geo-tag for the camera, and locations setting on FB.

It shouldn't matter. For what its worth, I'm not seeing anywhere close to what others have posted in terms of battery longevity. I use bluetooth for everything. Car stereo, bathroom speaker, gym headphones, etc. Wifi is always on, but connected 80% of the time. GPS rarely on. Screen time doesn't push past 2 hours and I can BARELY get about 1 day of battery life. I do use the stock charging cable, but I use others as well.
It seems like a big variance, even with drastic use differences.

Battery life is ok for me I guess. It gets me through a day. I am not impressed by the battery life at all, probably because I was spoiled with my old MAXX. I still expected at least a few more hours but something in the background sucks battery. When root comes, I'm sure battery life will improve a bunch. Its also not that big of a deal because the back is removable. What stinks is this is my battery life with power saving enabled for over 1/2 of the day. I really do not understand how people were getting over 10 hours of screen time and this day and a half battery life. The only way I get that is if I charge it before bed and count those 12 hours towards my battery life and I still wouldn't break 24 hours.
Maybe I'm missing something?
GPS is battery saving, print services are disabled, screen timeout at 15 seconds, screen is at auto brightness with adapt display, power saving enabled most of the time, wifi and 4g bounce between whichever is better, network mode is LTE/CDMA and I have disabled a ton of bloat. Maybe its because I have ART enabled.
Definitely not impressed by battery life but I am a heavy user and I love that you can swap batteries.

What does 'power saving mode' do? I can clearly see what 'ultra power saving mode does', but I was wondering if anyone knew what regular power saving mode does? I tried searching the Q&A forum but didn't find much and Googling it just led me to a bunch of pages touting the ultra power saving mode. Thanks in advance!

___ BATTERY LIFE THREAD ___ Being raped by Android OS!

Who is having issues with battery here? Android OS is killing my juice! I have gotten fed up and rooted my sheild and frozen most everything possible to try and get the OS down. I will lose like 30-40% overnight. I was thinking it was the shield or nvidia services tied into the android OS but that doesn't seem to be it. Blake_wavelock seems to have a lot of the activity and deep sleep isn't Happing as it should. I haven't tried WiFi off when screen is off and I'm going to use that tonight. I have all the location setting and Google setting inactive. I'm using optimized for battery.
Let me know what you think. I come from a posse of Samsung devices and get great battery life on them.(of course they are all rooted and ROM)

Have you checked under WiFi advanced settings for keeping WiFi off while screen off and WiFi optimization? (Sorry if these settings aren't there, looking at settings on my phone, as I don't have this tablet, but I am considering purchasing one).
Also, is your WiFi signal poor or strong? Because that plays a big role.

I have this happening with airplane mode on. Only seems to happen when I'm home though.
Weird.

Yesterday all was well til I messed around on chrome and a few other apps before bed. I was pretty sure I had skinned the cat until I woke up with 2% battery life and it was 35% before bed.:banghead:

Those with bad battery life should check what apps they have installed and use wakelock to find out what's keeping your tab awake over night. I have had many android devices and unusual battery life like many of you report is virtually always due to a user installed app or combo of apps. I get 3 days use on one charge MINIMUM. This is with WiFi on 24/7, and I use it for homework for several hours a day and some light gaming thru console mode (maybe an hour a day). I use a custom power mode with 50% cpu clock, 2 cores and 30 fps. I never take it off this power mode cuz I never see any difference in performance. Il post pics from next cycle.

Yea I'm not seeing bad standby either, battery overall isn't great but OK. I get about 5 hours screen on but most of my usage is android games.

That's more like it, still not what I call good but for something that offers everything I guess it's OK. Still wish I had a way of reaching 10 h screen on.

Twice now, I have gone from 70-80% to dead in just a few hours with the screen off. I have a few background apps with push notification (facebook, appy geek, mighty text) but they are all the same apps as on my oneplus one, and it only drains 1-2% per hour. Same with my Xperia Z Ultra (which I had set up as a tablet, no sim installed)

Go very dim and freeze everything and im sure you could get close! I do use greenify. I like app opps but to lazy to set it up.

I have the tegra note 7 and this shield. I pretty much just got both about a month ago. I have figured out that the WiFi hardware is not as good as most phones. So it will cause a wavelock and drain the device (which is labeled under android OS). So make sure under settings<wifi<advanced you choose WiFi off when screen is off or only when plugged and not to search for WiFi networks if you don't need. I have also seen that if you root then you can use titanium backup or whatever you like to freeze all the apps that cause harm or excessive battery drain. Also, with root you can use app called wavelock detector to figure out what app is draining you down. I have just about everything frozen except for updates and a couple other services. Good luck report back on what's causing it if you can. Blakewavelock got me, lol.
Here is this cycle from yesterday (still going) What wavelock detector looks like

I'm rooted. what can I do ?

What's wrong with my note 4 ?

Hi everyone,
I have a Note 4 (SM-N910F) running android 5.1.1 (build LMY47X.N910FXXU1COH4) for about 1 year and a half now and i'm so surprised of how the performance have decreased, plus i have some weird things happening every now and then such as :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Having no internet connection, but i'm on wi-fi. This doesn't come from the network i'm using because it happens even when i'm connected to a different one.
My battery life is really ****ty... Plus when i'm around 30%, my phone shuts down and when i turn it back on again, i'm like at 1%.
I'm not root.
I really don't know what to do. Is there any information i can give you that will give you tips on things i'm maybe doing wrong causing my phone to have weird behavior ?
The thing i want to know is if flashing a new rom was a good idea, and maybe if you have advices to give me on roms.. I'd like to be as up to date as possible, and a light rom. Doesn't care about touchwiz feature. I just want my phone to be reactive, fast, and working normally.
Thanks for your answers.

Change your battery. Some posters claim to have lag when their battery are nearly dying as well.

Do you update regularly (Apps & OTA update)?
Try to turn off WiFi & then turn it on again.
As for battery....it's degraded to only 70% of its full capacity.
Usually when it reaches around 40% your phone will stutter + lagging heavily, so make sure to charge at around 50% if you are still considering to use that "broken" battery.
My Advice is to buy a new OEM battery or any good 3rd party battery.

It is a little similar with my 2014 Note 10.1. It also shuts down on its own at right arount 33%. But only sometimes. And yes, it also stutters. I can not vouch for other branded devices. But, I have heard similar stories from friends on their Samsung devices. Definitely get a new battery. Like another post staited. OEM is a great choice. Or, at least a very reputable 3rd party. I purchased a battery for my Note 10. And even though it was new, it was not the same. I found that the circuitry in the cheap aftermarket battery was sub par. The seller sent me a free replacement battery. And it also had issues. So, make sure you get a reputable battery.

Batteries aren't linear though. Its voltage drops off in a curve. (e.g. 4.2v = 100%, 4.1v = 90% and 3.7v = 20%)

Same problem on my 10 months old Note 4 N910C. And it was started about 2-3 months ago, so the battery lasted about 6 months!? Also, there's a burned-in damage on my screen (notification bar)! Yes, warranty is still valid, but anyway... NEVER AGAIN Samsung phone!

You also need to look at your signal - it is awful and you have some wicked wake lock issues that need to be addressed.

Hm... You right about signal. I never looked at this, because whenever I use the phone (at home) and I'm always on 4G internet (unlimited plan), signal meter is on 1-2 bars.I don't know why is signal so bad, when phone is off. Power saving is always ON. About wake locks... I believe that they are from my smart watch (bluetooth),but Bluetooth version on Note4 should be low-power (connection is lost when I'm 4 meters away (in my department)), so... This days I can't reach 2h of SOT (4h-5h when it was new).

Interesting. I'm curious about the power saving if that actually reduces your signal by keeping it in a lower power state. I have never used power saving mode and my rom doesn't recommend it. I wonder if running in normal mode would effect it.
Might look at what apps are using the bulk of your battery as well to see if something rogue is running.

Before Note my phone was Sony Xperia Z and power saving on that phone did a great job.That's why I still use this feature. I also put many apps into the "optimizing mode"... There's no any special app which uses battery. There was Facebook, but I uninstall it.Battery monitoring apps are useless for me because phone is not rooted (still under warranty). Maybe I should try hard reset.

I know it's old thread, but anyway... Last week I finally take my phone to the service, because it's still under warranty. They changed the screen because it was burned-in, they changed the battery (sudden power-offs) and strangely - they changed some faulty system connector. Phone worked and charge befor the repair. I always use only original charger, so how can be some system connector burned??? They changed it for free under warranty, so I assume that it must be some factory fault. I know few people with the same "sudden power-off" problem on different Samsung phones, so...
