Unexpected great battery life - T-Mobile Samsung Galaxy S6

Picked up my phone yesterday afternoon and after receiving the OTA and factory resetting afterwards, my battery life has been fantastic on the first initial charge. My screen on time is at 6+ hours and still going.
I haven't done anything special. My phone is bone stock with only T Mobile bloat disabled.
Is anyone else getting ridiculous screen on time?

Is this just leaving the screen on and not doing anything?

No...Just my regular usage on a lazy Sunday night while in bed.
I'm on wifi.. with Wifi calling on, web browsing watching videos on youtube, a couple phone calls and heavy texting. Also have 3 gmail account with push notification.
Stats look funny with the cell standby on top of my usage. Usually it's the screen that's on top

I've been really impressed with the battery on this device. It's been more than enough to get me through an entire work day. The fast charge feature is great for a quick top off before a night out.

I don't think this is out of the ordinary, I think the question was standby + SOT. It's easier to get high SOT times if there is no standby associated. So 6hrs SOT while the phone has been off the charger for 7hrs isn't as big of a deal as 6hrs SOT + being off the charger for over 24hrs.

That Cell Standby too, damn...that's caused by having VoLTE and WiFi Calling on. Agree with what everyone else said, 6hrs SOT with the phone being on for 7hrs41min is not really a proper measure of your battery.

The real question is...why is cell standby the highest battery user if you've been on wifi with wifi-calling? this is what makes no sense.

I am able to last a full work day just streaming satellite radio and always on and off it throughout the day and still have a lot of a room to spare. Pleasantly suprised with how great the battery life is. Short of watching video's I am still at 30% range come night time. My S4 would of bottomed out at some point in the afternoon. I have to train myself to not have this phone plugged in every outlet I can lol.

That screen-on time.....
I get 4 hours max....... With whiped cache, VoLTE off, wi-fi scanning off, and wi-fi calling off.
Spotify and maps both slaughter the battery, but still.

Wifi/VoLTE calling
Yeah I've noticed that when on WiFi calling (with or without VoLTE enabled) phone never shuts down the radio. As in, I actually see both the signal strength indicator (crappy at my office) and WiFi calling, which never happened on my Lg G3 -- as soon as it goes on WiFi calling it'd turn off regular radio.
I bet that's the reason for big cell standby energy consumption.
Did anyone else notice this?

Whipe your cache and disable wifi-calling and volte. The radio won't consume so much battery afterwards.

Um... no. Without WiFi calling phone is useless. I was asking if anyone else had WiFi calling on and NO cell signal indicator at the same time

i get the wifi calling and no signal type indicator (IE 4g, LTE, etc) but i do get signal bars. This is exactly how it functioned on my g3 as well though with the lollipop update. If you want no bars showing, you have to change your wifi calling prefs to "never use cellar network"

Yeah my G3 before lollipop would simply remove the cellular indicator after about a second on the WiFi calling. I wonder if it's something that just changed in the system.
It's really annoying as previous behavior was exactly the logical one -- found WiFi, WiFi calling kicks in, regular radio gets turned off in a bit (hence no bars any more), if you go outside of WiFi coverage it turns back cell radio. Signal is so crappy at the office
Hopefully they'll fix it. I guess for now I have to keep switching "no cell at all, WiFi only" and back to "ok, cell but no WiFi calling". Ick.

I got 3 hours sot with 53% left to go. I have to say i am getting close to my note4 on this. I am very impressed so far.

Mine is doing well today. This is with Spotify and Snapchat usage.

Mine is getting better

So WiFi calling and volte on?

Yes to volte I don't use WiFi calling

I have airplane mode on, wifi calling, while I'm at home. Saves the most battery.

How to handle battery usage in 3g/wifi to remain always online

Hello,
I subscripted to a data plan with my carrier and I was wondering what is the best way to handle this situation to remain always online.
I have wifi and 3g on so when I'm home or in a place where wifi is available it connects to that network and disable mobile data and opposite when I go outside wifi coverage.
But I noticed two major problems
- I went out for 30 minutes, the phone switched to 3g and the battery went down 7% without turning the display on! I walked and the coverage is extremely good where I went plus I noticed that the wifi icon was still on so it wasn't really disabled
- When I came back the phone didn't go back to wifi connection and kept staying in 3g until I open wifi settings manually. This is a bug with cm7 I already reported!
Those things don't happen always but they do happen. Does 3g in "idle" consume so much battery power?? If yes The phone would die in 8h without even using it if I used it according to this rate it would die in 3h
My guess is that some of the phones may have some hardware issues, because the software is identical, but only a small part of them drain the battery when using 3G.
I have a similar issue: http://forum.xda-developers.com/showthread.php?t=1501047
edit: my Froyo drain was normal, 1% per hour, vs GB (stock, CM7, etc) which takes 5% per h. This would be an argument against a hardware defect...

Power recommendations...

Ok Guys,
Kind of a weird question, but I'm using one of the ICS leak ROMS.
With general usage, 4G/wifi, I would get between 18 to 20 hours, which for me is perfectly fine. The more wifi, the more battery time. No issues at all.
Recently, our office moved where we have a dead zone. I do have full wifi access, however being in this area absolutely kills the battery. I lose 12% every hour. As a precaution, I have disabled the mobile data, and confirmed wifi is working. I have confirmed that I can make and receive calls, and send/recivee txt msgs. However, battery results are the same. Is there anything else I could try?
I'm guessing, being in a deadzone, the phone is putting in overtime trying to find a tower....
Anyone have any ideas?
Thanks in advance...
Interesting... On my Bionic with the .232 leak the option to change network types is grayed out. I was thinking if you set it to 4G or 3G only it would save some battery since the analog radio sure do suck down power (if it even tries to use that as an option).
Not sure what to do. Hopefully somebody can provide something useful.

You can definitely try out a couple of apps from the appstore to change your radio settings in one of the ICS leaks. The first is called "Phone Info" and the second is called "LTE OnOFF - HTC Thunderbolt". See if going with 3g (CDMA auto prl works well for me) only will help your cause.
You could turn the radio completely off, but then you obviously wouldn't get calls, texts, etc.
Ok Guys
Here are my findings...
Looking back, it seems during my move, I also upgraded from Eclipse 2.1 to Liquid ICS around that timeframe. So I back tracked and installed eclipse 2.1 and tested. Here are my findings:
on Liquid ICS 1.5mr:
In deadzone in my office, with wifi turned on, mobile data disabled, I get barely 1 hour per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2.5 hours per 10%
I re-flashed Eclipse, this is what I found
on Eclipse 2.1
In deadzone in my office, with wifi turned on, mobile data disabled, I get approx 2.5 hours per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2 hours per 10%
Overall, the ICS battery usage seems to be much better under normal conditions. In a deadzone, seems to eat away much more battery, even when mobile data is disabled. I'm geussing that its prob checking for a tower much more often then GB?
Any help would greatly be appreciated.....Thanks!
Hey Guys
Just wanted to update you on my findings....
Ok, after playign around, here is what i did. With WIFI turned on, I was getting barely half a bar in the radio signal. For a goof, with WIFI turned on, I went into phone info, and disabled the radio, and re-enabled it. within 2 sec, the radio came up and got half a bar again, but a few sec right after that, I got like 4 or 5 bars. After testing in this state, i get roughly 5 to 6% depletion per hour. WHich is MUCHHHH better.
I have a feeling that with WIFI turned on (mobile data seems to be disabled when in wifi mode), and u turn on the radio, that it connects to a different tower entirely. Because when I walk outside, and disconnect wifi, it goes to 4G, but then u can see it go from 4 to 5 bars, to 3 bars which is normal for me for that area.
Hope this helps someone....but it helped me a great deal.

[Q] Is this normal battery drain?

My cell standby is really really high and I'm nowhere near the 6+ hours SoT that people seem to be getting here. I even followed the battery optimization guide and disable all the moto features on the phone. I also changed my preferred network type from "Global" to "LTE/CDMA" to supposedly save more power.
Is anyone else having odd drain? I attached a list of the apps I disabled as well.
Cell stand bye does seem high. Silly but I'm sure you have turned phone off and fully charged to see if it remedies?
All else fails factory reset, I know it's a pain.

I charged it while it was on fully after draining it to 1% when I first bought it. I have not turned it off or charged while it was off. I'll do that later when it is around 5% after work.
How would the factory reset help? I would reinstall the same apps again anyway so if that is the problem I wouldn't know it.
I didnt mess with any network settings but cell standby is higher than screen on my battery stats. My battery life isn't bad by any means but not as good as some others are getting
I've seen this issue reported by 2-3 other users, it's either related to the cell coverage in your area or might even be a faulty radio. Cell standby is usually high on my list but still about 1/4 of the power draw of my screen (assuming my average SoT of 6 hours) and around -96dBm (3-4 bars) signal strength. Try checking your signal strength - if you don't have an app for it, do: Settings > Wireless and Networks > More > Mobile Networks > Network type and strength.
I have this issue. My signal sucks at home. Only 3 bars most of the time.

Same issue here ... Just switched to ART and I'm going to switch from global to LTE/CDMA to see if I can knock it down a bit. Reception at my work is terrible in some spots (hospital). At home its not so bad.

Urbane 2 battery life without LTE

I was wondering if the battery would be good if it was used without a sim card and all the cellular features? I'm considering this watch because of the design. It does have a huge 570mah battery and I wouldnt use its cellular features. Thanks

I lose 3-4% an hour with cellular off and paired by bluetooth.

so it seems there isnt much of a difference compared to my sony smartwatch 3 which i get 2 to 3% loss an hour and it has a smaller battery at 400mah. I'm guessing probably that cellular hardware modules are draining the power, even though its not being used. it would be great to see the same watch without cellular function and same large battery. thanks

By cellular off, do you have it in airplane mode or just left the SIM out and cellular set to automatic? I have mine in airplane right now, figuring that would save more battery, because I couldn't find a way to change cellular from "automatic" to "off" unless it was bugged or something.

I just turn cellular off. When I leave the phone behind I turn cellular to automatic to activate the SIM. When paired by bluetooth I just toggle cellular to off. Occasionally when I go out of bt range cellular will switch back to automatic on it's own. Most of the time mine will stay off. I never use airplane mode.

I was able to turn off cellular without putting on Airplane mode after restarting the watch.
I used it heavily this weekend for GPS navigation, tracking on a 5K, notifications, phone calls (via BT), and ambient display always on. The watch never went below 50% during a single day of fairly heavy use. With the display off, I imagine it could get 2.5-3 days easily. 2 days should be do-able with the display always on, but I turn it off at night just to combat any chance of screen burn since we don't know how well this P-OLED will handle it.
Today my battery is at 98% after about 8 hours of use.
I get email notifications, etc. This is with cellular radio and wifi off.
It shows remaining battery of 3 days.

That's impossible. Even if you disable the always on display. Your watch just isn't reporting the battery correctly. Might take a few cycles to get the battery level settled in. And if nothing else, I have noticed mine stays above 90% for awhile then drops off quicker.
You guys are doing much better than I am. I can take the watch off the charger, goto the office and be at 90% in less than an hour with LTE on. I can't get more than 4 hours with LTE on on this watch. I think it has to do with crappy signal strength, but what do I know? I just leave cellular turned off. Taked to LG and might send them the watch back to take a look at it.

I'd say if the signal reception is bad, that's definitely the reason. I've read several posts with this being the reason the battery drops fast. An example, I lose about 25%-30% an hour when I'm tracking runs with GPS, playing music through bluetooth and with cellular on paired to my phone that I leave behind. The cell signal in my area is good. A friend loses 60% an hour doing the same thing in a poor signal area. I lose about 3% an hour with normal usage and cell radio off.

S10e wifi battery drain?

I got my S10e exynos a little over a week ago and gave it some good weekday battery life testing throughout the this past work week.
The screenshot is after a day of work, with the vast majority of the time on LTE and noticing massive WiFi drain. I've noticed that WiFi drains between 25-45% no matter if I'm using WiFi the majority of the time or not. Compared to my Pixel 3 that drains 5-10% from WiFi.
Anyone else getting WiFi drain? Could someone with a S10e SD855 post some battery stats? Please use gsam if possible.
Is your WiFi scanning turned on?

Hard to determine which of these options would be considered "WiFi scanning", but they're all off except LTE switch over.
Just search wifi scanning and Bluetooth scanning
Biometrics and security, location, improve accuracy, turn off wifi / bluetooth scanning.
connections, wifi, advanced, I disabled the "switch to mobile data" to get better battery
Yes I am having this issue as well on my S10+ US Unlocked version. 1.5 hours of screen on time draining 5%, WIFI draining 8%. Doesn't make any sense. All o fmy WIFI scanning and auto switching is turned off.
Someone said it is because the phone doesn't go back to sleep on Exynos models after you've received a phone call
A reboot fixes it until your next phone call
Patch should fix it
Reboot doesn't fix it for me. I also have had two different s10s so it is definitely something software related. It drains so Mich that I keep wifi off unless I absolutely need it.
