Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note 7 before depleting the battery.
Then, drop a comment if you have anything to add!

Got 6 hours sot on my first usage starting at 90%, wifi only - internet/youtube/light gaming
Not impressive but decent, not as terrible as I thought sd820 was going to be aside from it being hot

Could be better but with all of the battery saving features you get, I don't have any issues with how long the battery lasts with the screen on.

You can also change the resolution to FHD. It will increase the SOT and FPS while playing videogames Great new feature :good:

6 hours of heavy usage with LTE would be very impressive, S7E exynos can pull off 6-7 hours in that regard.
6 hours with wifi and light usage is pretty typical even for mid range phones, my 7 years old iphone can pull off similar results in airplane mode.

No ****, eh? I am beyond happy with the SOT with this phone... hell, the battery period. My POS LG G3 couldn't go more than 3.5 hours SOT with light to moderate usage.

U are saying iphone 3gs was capable of 6 hours of usage

Lol standby or airplane mide note 7 would last a week. Easy.

Mine clocked 8 hrs with wifi, you tube, moderate gaming and online music.

I've managed about 17hrs SOT on my Note 5 once*
*Attatched to a battery pack lol

Snapdragon model note 7. Had 6 hours 30 minutes of screen on time, 3 more hours of standby, WiFi, Bluetooth, WiFi calling, and AOD all active, location set to battery saving, none of the power saving features active, spent lots of time in Firefox and Facebook messenger, watched a full movie from SD card at 100% brightness, sketched in autodesk sketchbook with the s pen for maybe an hour, and I still have 35% remaining. Been at full bars of reception all day, though, so no drain from low signal. Either way, I'm impressed. Especially coming from my HTC one m9, haha. And the phone stayed pretty cool all day, especially compared to the m9.

Hi, I'm looking at around 5 hours of SOT.
I believe I am experiencing severe battery drain on my phone. My phone doesn't last a complete day without needing a recharge.
Here are some quick stats.
- My phone has been on for 6h20m. Screen on for 2h17mn. Battery left is 58%. Although, I've turned on MAX power saving mode for about 1 hour or two today to ensure that my phone can last throughout the day.
- I usually have screen brightness at 50% or lower.
- According to the device maintenance app, and depending on past usage I have enough juice for another 6h50mn. That would lead to screen time of about 4 to 5 hours.
- I'm using dark themes whenever possible to reduce screen battery consumption.
- I've played a game for about 10 to 20 minutes today
- I've noticed that when my screen is on, every couple of minutes (maybe 5 minutes at the most) my battery percentage will drop by 1%.
- I mainly use my phone for gReader (RSS Reader with dark theme modee), WhatsApp (with black wallpaper) and the Economist.
- The top 3 items that have consumed my battery so far are: Screen (33%), Android OS (21%), Andoroid System (16%)
- I'm using two SIMs on my phone
- Believed to be Exynos. Bought it from the Middle East
- Always on Dispaly has 4 clocks on at all times. Probably using more battery.
Am I a heavy user hence why my battery is running out quickly. Or are there certainly issues with the battery?
Thanks for your feedback

I feel as if I'm getting horrible battery life as well. Been hard to tell being that I have horrible signal at work, if it doesn't improve with real world usage this weekend I'm going to phone att for a replacement.

SOT is a useless measure on it's own, doesn't tell anything about the battery life. I doubt you can get 6h SOT and that your phone can last until the end of the day. Yesterday I got about 4h SOT and around 14h uptime before I plugged it in again. Can't say that I am unhappy with that.

5 hours of playing Deemo and have 14% remaining, probably going to refund it for a S7E with exynos instead or keep it and sell it before S8 launches
Wifi only, brightness was around 30% auto. Not a gpu intensive game at all so not as impressive as it sounds. I believe the S7E exynos did 5 hours of pokemon go with max brightness.

I'm getting great battery. Better than my Nexus 6P, which I didn't expect. Seemed to run hot day 2, not day 3. Not...sure why. Love the power options, normally I hate to touch power saving.

Quoting myself here. Day 4 with the phone, 4:10 SOT with 18 h of on-battery time. Battery went down to 4%. Just a normal use, few videos, lots of music played (Deezer and Pandora), about 30m of Pokemon Go, news, etc. Once again, not unhappy with the results. I would prefer if I have another 5-10% left to account for the unexpected. Otherwise, all good.

Battery usage

My battery stats have improved greatly by turning off location completely.
Took it off charge at 6am and with heavy usage
YouTube internet calls etc
still have 65% 16.5 hrs later.:good:

Just starting to play with battery use on my new G5. 100% charged 10 hours ago just before bed.
On a day to day basis i am a pretty light user. Calls and texts mainly.
Left phone unpluggged so it slept and 7 1/2 hours layer its at 93%.
20 mins music and email checking 19 hours in its at 88%.
Have Greenified much in the way of apps which i think improved things. Compared to the Sony i had the G5 seems to have ok battery life.
Its certainly in the useful, full day and better range.

Is yours rooted? I tend to get 5+ hours screen on time sometimes 7 which is amazing for a phone this cheap.

Same here, I have about 4-5 hours of screen on time with greenify, non-rooted. I'm a regular user, messenger, emailing, browsing, spotify etc. I'm also using Adguard which has its impact on the battery but a small price compared to having ads all over the place

Nope, no root as yet. And actually i may not depending on what ROMS become available in the future. Pretty happy with the way this is setting up and Android 7.0 stock. I think i may well leave it unrooted until after Android O hits and see where i go from there.

i'm rooted and the battery is very good, i got 7,5 hours SOT, usually i have 5-6 H of calls and 3H of SOT, 2 sims active, wifi and 4g always on, and the battery is 20-25% when i put on charging from evening to the morning. Very happy with this battery

Very good battery for price of the handset

I don´t know it´s a isolated case, but since i bought the phone, the battery is pretty bad, yesterday i tried to charge with another power adapter and my battery it´s lasting longer, anyone have this same problem?

Sometimes this happens to me.
When i keep my phone overnight(Battery Saver ON) even wid a charge of 60-70%, next day mrng, the battery is completely drained and phone is OFF. This doesnt happen daily, happens only sometimes. Any guesses why dis happens?

Bought new Z play/kind of disappointed with the battery life

Hello all,
I bought a new Z play to replace my ageing phone, and I have mixed feelings about the battery life. The phone has received universal praise for its battery life, and while some of it is true in my case, I can't seem to get those high SoT numbers that everyone brags about.
It's very difficult for me to break the 6h SoT barrier, and I consider myself a light user: whatsapp, browsing, some reddit, and the occasional music (through headphones). I don't play any games, or perform heavy tasks. Also the phone is connected to WiFi 85% of the time, get decent signal, and the screen is set on auto-brightness.
Running latest version of the stock rom, and I performed factory reset + wiped cache + reset network settings countless times as per suggestions.
Attached some stats for 50% that I just took.
Is there something I'm missing?

Take it with a grain of salt, just because people brag about numbers does not mean they are real or obtainable by everyone. Battery life will vary for every user and phone. The time you have is in the acceptable range and I would not worry.

Yes, even I have never achieved the 8-9+ hrs of SOT that's I've seen in some threads. Based on my usage I get a minimum of 6.5hr SOT with the phone lasting a good 25-27 hours before I have to plug it back in.
Since the phone is new it might take a few cycles for the battery to truly show its stamina.

Those answer are definitely right. It all varies on the users. . Also please makes sure you have bluetooth and wifi scanning off. (Location> Scanning > Bluetooth & Wifi Scanning) Another factor is apps. Get rid of facebook and facebook messenger. Apps that use GCM eat battery like a range rover eats gas. I've hit 8--10 hr of SOT before. Let your phone get use to your daily activities. I believe it'll optimize itself over time.

It's normal.
I was also getting earlier 5-6 hrs SOT(When the device was new) but not I'm getting 8-9 hrs SOT.
So as your phone is new it might take few cycles for the battery to show its full stamina!
Cheers!!

Thanks for the replies and for putting my mind at ease.
Bluetooth and wifi scanning are off (forgot to mention that).
Anyway, I understand. Those insane SoT of 10+ are best case scenarios with careful use of the device. Still happy with my current capacity (anything which lasts until the next morning is great).
And yep, the phone manual (who reads those anymore), did mention the battery taking a few cycles before reaching its capacity.
Now, for a different issue. If I'd like to disable turbocharging/quickcharging my phone, would a USB C to A cable coupled with any charger (including the quickcharging ones) do the trick? Based on my understanding, the cable limits the chargining power, so any regular (quality) C to A cable should restore normal charging speeds even when using a fast charging charger. In case you're wondering why I'd like to do that, it's because the phone gets way too hot for my liking when using the Moto turbocharger and I'd like to reserve that for when necessary.

Well, guyz do have a point.
The screenshots are showing you have almost 3hrs SoT after day and a half. This is normal.
Those >10 hrs of SoT aren't achieved with careful usage. Coming from my experience, I got 10.5 hrs SoT with 10% battery left, BUT, in one day. My Moto can last up to 3 day with one charge, but in those 3 days I'll have maybe 4hrs SoT. So, in average, my Moto lasts up to 2 days with 6/7hrs SoT (I mostly use FB, Messenger, WhatsApp, Viber, YT, Instagram, stock 6.0.1). It simply depends how you use it. That big, almost 11hrs SoT, I could only achieve on weekends, coz otherwise I don't have the time to stare in my phone so much.
On that other thing, Moto does get pretty hot while charging. And you're right, the cable does limit the charging power so it will probably work.

I was one of those users getting 10h SoT early on. But I was doing that inside a 24h usage window. Your 50% stats have you stretched out to like almost 3 days off charger. Idle time vs. screen on time is ALWAYS a trade-off.
I look at battery drain in terms of drain rate at idle, and drain rate with screen on. Early on I was seeing 6% drain per hour of screen on, and 1-1.5% per hour screen off. So basically 5 hours of idle time costs you 1 hour screen on. Those were my numbers on the original MM build. My battery life has gotten worse with every software update. I have NOT done a factory reset, mostly because I don't want the hassle and I still get a day off normal use with plenty of battery to spare. But I usually see 18h off charger and 3-4h SoT in a normal day, and that leaves me at 40-50% when I plug in.
Looking at your stats, if screen on costs you 6% per hour, you have 17% worth of screen on drain. That leaves 33% idle drain over 38 hours, or sightly less than 1% per hour idle. Seems pretty darn good to me.

Your cell signal is definitely not helping your battery life. Switch to 2g when on wifi, your signal bar should be full and it'll probably help your battery life.

Enjoy the fact that this phone lets you keep BT/WiFi scanning/Facebook/etc. on without having to worry whether or not you're going to make it a full day. I use all that stuff, have multiple live widgets updating, brightness at least half way, T-Mobile Digits running, and still make it a full day. Additionally, it's great to know that if you do have to make it 2-3 days with minimal usage because you don't have a charger handy, you can. However, I'm willing to bet that 99% of users are able to charge their phone daily. To those users, I say enjoy all the features and don't worry about it.

Really depends on the screen brightness...I can hit those number with my screen brightness turned down a good bit...probably around 30 percent and auto sync off...if i have brightness anywhere above 60 percent then battery life drops a good amount...still well enough to get me through a 12 hour work day but there is a difference

Good way to measure battery life?

I've been using a Pixel 3 XL for about a month and I'm not sure if there's something wrong with my battery life or not. There reason I worry is that I've ready a lot of posts online of people seeing they typically get 5 to 6 hours of SOT sessions, or even more, across a day, which I'm sure it would be impossible for me to achieve – I'm more like 3 hours SOT over a day session. However, given that SOT is not the best indicator, I was wondering if there is a good way for me to actually test if there's anything wrong with my battery?
Some details about my usage below. I would also appreciate if people could tell me if anything seems weird about the battery life I'm getting out:
I'm a light-to-moderate user, I charge once about every 24 hours and probably get around 2.5 to 3 hours of SOT in between charges. I recharge at around 20% usually.
Location is always on. Auto-brightness. I'm on Google Fi, so LTE is on, but 95% of the day I'm connected to good signal WiFi.
My overnight drain, with WiFi, data, and AOD off, is 4 to 5%.
I've been using AccuBattery and BBS and I don't think I have any rogue apps or weird wakelocks. I've got 100% battery health, and AccuBattery says my avg Screen on usage is 16.3%/h. With Screen Off is 1.2%/h (that's with ~2 hours every day used with screen off for Spotify or podcasts).
The most I've pushed the battery is to watch YouTube videos on it continuously one day, and I went from 100% to 15% over 4.5 hours of continuous streaming.
Thank you!

Sorry but that doesn't make sense. That's about 5 hours SOT from a full battery right there.

Sorry, I guess I wasn't clear enough.
So I could get 5 hours SOT if all I do is watch YouTube videos, no standby time, no other usage. So the phone would be dead in 5 hours. 5 hours SOT in a 5 hour session. But if I use my phone naturally through out the day, I get about 3 hours SOT for a 24-hour session. The posts I've seen from other people is that they get 5-6 hours SOT in a day-long session (18 to 24 hours). So in comparison my real-life use seems to not last as much as theirs.

Question battery hours screen and advice?

hi, I would like to buy Fold 4 but my fear is the screen hours are a bit short on average, how long does it last for you? and if there are more in-depth tips to extend the battery!

I get more than 20 hours of heavy work , with about 4.5 hours of screen on, This is my daily 'office' with three email accounts pushing real time emails , Wifi or 5G UC conncetivity at all times, big screen used about an hour of the the 4.5 to review and sign documents and use CRM tools that reqiure a bigger screen , when I do not have the laptop out of the bag, especially when traveling. No gaming, music, etc. but on the other hand I never use the 'power saving' mode. Here is a snapshot of my phone after it left the charger almost 9 hours ago, 3.5 hours screen on, 5.5 hours off but apps run in the background and 65% still avilable. I am on the phone on calls often, text, email, and use the big screen constantly, and never saw below 25% battery at the end of my day , 12-13 hours after my day starts. Of course , if all you want it to be playing games with 100% CPU utilization , big screen on , QHD 120 Hz refresh rate at all times, speakers on at 150% your experience might be different. This phone, IMHO, is more business like and does the job.

same here, with normal use I usually get 4,5 hours of screen on time with 8 hours or so of the screen off time. I think z fold 4 normal use will have 4 hours screen on time

I get 7 or 8 hours of SOT when using WiFi at home. Out & about on 5G I usually get around 6 hours of SOT.
I mainly browse the web, take calls and use WhatsApp. This is per 24 hrs inbetween charges. My phone goes into Airplane mode (with WiFi off) at bedtime.
