Battery life is ****! - Samsung Galaxy Note 8 Questions and Answers

Don't k kw what I am doing wrong. Not doing any fancy stuff. Screen in time 1hour and already down to 65%..?

Well, there's a lot of things that can affect the phone:
1. What's your screen resolution at?
2. What were you doing for that hour? Using active aps with constant data transfer (like streaming services or live games)?
3. How bright is your screen set? I keep mine at about 35%
4. Are you running any of the battery saver options?
5. What's your performance mode set to?
With my screen resolution dropped down to the lowest setting, my brightness at 35%, and no power saving features, I can read for three and a half hours on the FanFiction app, and not even drop to 70%.

Boot up in safe mode and see if it still bad. If not, is the crap you installed, if it is, then something with the system, probably some settings. Also, if you just got the phone, give it few days, it's probably syncing and updating. Mine is at 9 hrs since full charge, 1h 10min SOT plus 1 hour AOD I'm at 80% and I know I can do better if I put some effort in it. I got everything on, max resolution, NFC, BT, GPS, wifi it's all on.

display -- sucking up my battery life

Hello, my phones battery life is I'd say average.
I get up in the morning after its been charging all night, and after its been unplugged for maybe a half hour, with a few texts and a minute of browsing done, the battery has gone down 5%.
Battery usage shows that display is taking up 89% of the usage!
Why is this? Is it normal? If not, how can I fix this?
Display will use most anyway. Get a darker home screen, either use low brightness or auto-brightness. not much else you can do.
Let me guess you're using CyanogenMod?
I've seen reports of my same problem, and those that had it found a solution by wiping the battery statistics, letting it die, then charging it to 100%
But no, my nexus isn't even rooted.
Strange. Before I was rooted my display would always be 1st or 2nd, along with android OS
After I rooted using Cyan, it was always 1st taking up more than 60%
Then I switched ROMS now its always 3rd or even 4th
Sorry dude.. try wiping batty stats and changing your brightness.. are you using live wallpaper? what about screen timeout.

has anyone thought that the battery usage stats has to equal 100% so if the operating system on CM is running lighter (usin the cpu less or in a more efficient way) then the display would be taking more % of battery usage making people think there is something wrong when probably there is nothing wrong. maybe the desire ports (modaco ro king) use more cpu and thats why the display is 3rd or 2nd.

This is perfectly normal. Displays are power hungry relative to the rest of the phones components.
Google maybe shouldn't have included the battery usage page as it just leads to confusion. When you use up 5% of your battery's power and then check the stats and see that the display is listed at 89% it means that of the 5% used, 89% went to powering the display. It does not mean that the screen has used 89% of your total battery at that point.
Leave the phone alone for a while and you'll see that the display percentage will go down while things such as Cell standby will go up.

Nobody thinks of that
-------------------------
I am on more than 9h of use still 50% battery left!
- Autobrightness on
- No taskkiller!!
- Wifi on all the time
...and using it today a lot, mails, web, twitter,....-> made a logcat this morning and eliminated my battery drainers
Agh! I want better battery life! I feel like it's dying much too quickly....
buy a bigger battery
or stop fiddling with it so much, lol
turn the brightness down. turn the sync off. turn off background data. don't use bluetooth or wifi. turn off your location.
don't use live wallpaper, use a darker screen that doesn't move.
i know on my winmo phone if i turned on bluetooth, battery would just get sucked out. i couldn't charge
it as fast as bt used it up. and that was with a fastcharge reg edit.
I believe you just got your phone, right?
It's cause you're playing with it so much.
I dont feel like I am though. I am using it probably just as much as I use any other phone I've had.
Maybe the battery just needs to be broken in.

Nobody ever thinks of that unfortunately. I would think display using the most would mean you're using a pretty efficient device.
Yup. That if you want to keep your battery as long as it can get. Else, if you want to enjoy your phone, buy a spare battery along with the desktop charger and you will survive a day...

I switched to enoms which gave me a little better battery life. Also downloading juice defender made a noticable difference, I use the free version at the default settings. I also switched email to hourly which is adaquate for me. I dont run bluetooth unless I am using it, same with wifi, which is what I do with all my phones. I dont otherwise change my usage, dim the screen etc. Overall I make it through the day with typically about 35% left. Based on what I see here my usage would probably fall into the light to moderate range. To be honest I havent had a smartphone recently that did much better. I pretty much figure I gotta plug in every night in the modern phone world.

As others have mentioned, the display uses the same amount of power no matter what rom you are using. So if display is 3rd or 4th, you have an absolutely crappy rom that is using battery probably 10x as fast (compared to same usage where display is 90% of the battery).
In simple terms, the higher % your battery is using, the more efficient your phone is being.*
*compared to same usage at same brightness running different software.
An addendum to juice defender. I had it on the default setting but changed schedule so that it lit up apn for 3 minutes out of fifteen instead of one, my email wasnt consitently downloading at one minute.
I noticed that you have gone to 5.0.6, how is your batt life now? I stayed away from it just because of the overrwhelming number of bad battery life posts on it and was surprised you went that way.

HTC Desire Battery Fix

Has anyone tried the HTC Desire battery fix and confirms it works on the SGS?
http://forum.xda-developers.com/showthread.php?t=755903
Some people have implied it works but I'd like to know what you think?
Yesterday i was make all from this HTC Desire thread give, except wipe battery stats because i not found this thing in clockwork recovery menu, and i can say , it work for our device too. My Galaxy S battery last pretty better-smoother:
After all, i powered on my device in midnight 00:00, morning about 8:00 was battery 100% too. Standby without APN connection, recieved one SMS only.About 10:30 was 99% have one short about minute,recieved call. On 12:00 make APN conection (2G) and about 20 min was on the internet, some news page, company pages, etc., and battery dropped to 97%, about 14:00 some calls 3-4 min, dropped to 95%. On 15:00 was on the APN about half hour,battery go on 93%. To now on 19:00 hour battery is on 92%...I think this is great thing, beause before my galaxy was from 100% to empty about one and half day....
Next thing i use only when i need it, usualy stay:
1.WiFi off
2.APN only when need Internet(2G), rest is off
3.Bluetooth off
4. Animation off (in Settings)
5.Autorotate off
6.GPS off
7.Network location off
8.Autosync off
Best regards
PS (Sorry if my english is bad)
Just given this a try...will report back in a few days.
I tried it... i didnt notice a SIGNIFICANT change... although i did switch from ryan's lagfix to the voodoo one... so that maybe have had an effect. Overall it feels like the battery life is about the same...
Also no change for me, after 8 hours of use with wifi or 3g on whole time, dropped 35%.
I forgett say, i have stock I9000XXJF3 rooted firmware,newer reflashed any other firmware, none lagfix apk, or other etc. system things apk, expect task manager and startup manager... From 19:00 when a haved 92%, and now on 1:20 i have 89% with 15 minute calling, 4 SMS sended/recived, about half hour internet surfing on 2G, and 10 min play bubbles game. Tommorow i will tried GPS lasting and wifi. For me more than fantastic battery duration...I was Make exactly how read on HTC Desire thread, except wipe battery stats, but reboot i was make from recovery menu, not usualy with on/off button or some reboot apk, becaus, i think maybe battery stats itself refreshed-calibrated !?
Best regards
Well, I did this last night, and my phones battery status is now showing 98% after 11.5 hours.
To be fair, I was asleep for most of this time, and have only brought the phone out of standby a couple of times to check the time.
I also have APN/bluetooth/Wifi switched off, and i'm using only 2g networks.
Still, 2% in almost 12 hours isn't bad is it?
Nope....
I just tried it this morning. I still have the same battery consumption per hour with the same amount of using the phone. So I guess it's not working for me.

Wow, that's seriously amazing guys. No noticeable improvements here. Followed the procedure, it was 100% at 8am. It's 6pm now, and after around 25 texts, 75 minutes of 2g calls and 5 minutes of 2g browsing, I now have 27% battery left. Doesn't seem like anything has improved.
I'm on JM7 with voodoo, btw.

have good succes with disabling power saving mode, so the brightness mode only is, as i set to be, my batterytime has improve significant.

Yeah, and power saving mode on the display is annoying anyways.
This method seems like voodoo (not the lagfix voodoo), but many people on many devices seem to swear by it.
If you're not happy with battery life, get spare parts off the market and look into what's eating up the battery life. Check your data-sucking widgets, wifi sleep policy, screen brightness settings, etc. Get rid of those apps that are mis-behaving and turn down the frequency on widget data.
Wiping batterystats.bin file after a full charge usually helps if you haven't tried that.
Also, if this is your first smartphone with a big bright display and a fast cpu, get used to the fact that the battery isn't going to last as long as your Razr did, not anywhere near as long.
Get a spare battery (the SGS battery is so thin it fits in my wallet without even noticing it's there, get a spare desk charger for your office and keep a charger in the car. Dock/charge the thing when you have the chance to keep the % up while you're away from the charger, and stop worrying over this.
With virtually every new "ROM" I follow on this device and the Nexus One, the first and biggest complaint is usually "battery life sucks" in the early release stage; then the complaints start disappearing as the battery stats get a chance to settle down.
Yes, I did tried that 'HTC Desire' Method.
On my previous firmware JM5,
80% 18hrs
74% 1 Day 1 hrs 47min
And lasted until the 3rd day before I had to plug in the charger. All this with Wifi off and idling most of the time.
For JPC,
The battery level was awful until I applied the wifi fix for JPc
http://forum.xda-developers.com/showthread.php?t=774507&page=5
Currently, my galaxy s is on 28% approaching 3 days (72 hours). So i guess in my case the battery level did improved. All this with playing games, wifi on (off when the screen is off) and movies. So the usage definitely increased, yet the battery still stands strong
Oh and another thing, the brightness level on JM5 was 30 (android lowest). I discovered Dimmer after that, which promptly reduced the brightess to 10 for JPC. That might explain the better battery part a bit
erm why does disabling power saving mode increase the battery life? i thought it supposes to save the power instead? My brightness is already set to the lowest means i dont need to enable power saving mode? wads the difference of enabling and dis-enabling.
Same question. Then why it's called Power Saving mode?

During this mode, the screen's brightness will adjust to the color/intensity of the image projected on your screen. If the image is bright, the brightness will go down in order to safe battery life.
If the image is dark (like most of the SGS's UI) it will increase the brightness because dark colors don't drain as much of the battery.
This sounds pretty confusing, but when you think about it, it makes sense.
I disabled this mode, because i think i conflicts with the automatic brightness setting =D
QuickSettings did the trick for me, if i'm in a dark area i disable automatic brightness and go for the lowest setting (Still brighter than an Acer Liquid or HTC Desire if you ask me ! AMOLED IS GREAT !)
So basically it means that by disabling the power saving mode save the power more instead? As it does nt increase the brightness nor decrease automatically?

I have tried this desire fix and it achieved no improvement at all.
I have heard that the best thing is to let battery drain then charge whilst phone is off.. but its too impractical to do this all the time..
I may be wrong but wasn't someone with good battery life going to share the batterystat file? was there someone mentioning a fix like this?
Also if you have 3 batteries how does that tie into the battery stats file.. after GPS fixing this is now seeming like a big problem, a few people i know and from an Australian forum have been disappointed with the battery life, and some people on here are getting 2-3 days
A guy from work tested it before taking it back and without sim, network, wifi etc got 23 hours in standby.
The website states something like 300 hours in standby? I think that is BS in fact on the samsung galaxy Australian site, they have replaced the battery standby to TBA...
Anyway after samsung took his device and 'tested it' they said the hardware was all okay, here is the new firmware.
As soon as I see him I will report what fw samsung gave him to 'fix' his battery life.
I call shannigans on samsung.... again!

A you sure is not in backgrond AutoSync, or GPS, or Network location is off. And very important make exatly procedure step by step from Desire thread...Im now after 38 hours (day and half) on 70% with my usual using (about hour 2G internet, 30 minute call, 4-5 SMS, and 10 min GPS with network location. BUT ALL MAKE OFF AFTER USING, when go on Standby)....Impresive realy?
I thinking make same procedure with my old HTC Touch Diamond 2...

Charge with phone off while you sleep shouldn't be too hard, unless you need the phone for incoming calls or alarms.
I don't believe batterystats.bin can be shared amongst phones, it's really just a log of your own phone's battery performance, if I understand it correctly.
Three batteries (like you and I have) will almost certainly confuse the battterystats file, unless all three batteries have exactly the same performance characteristics.
300 hours in standby...? Well, those kind of stats are always under "optimal" conditions. Optimal for any smartphone would be to have the phone in 2G only, wifi off, BT off, syncing off, all widgets off, location off, etc, etc, etc; basically just your phone in cell standby and not being used for anything else. My Nexus One, which gets little to no use now, used to last no more than 18 hours as my everyday phone, now with Froyo on it, a few weather widgets, wifi on, location on, etc, etc, it will last several days off the charger. I think we all just use our phones a LOT more than we realize, and that the display chews up more battery than we think.
Looking forward to what new firmware Sammy gives your friend.
This really helped me and I'm dead serious, after flashing a lot of roms and somtimes charging to only 50-70 percent and then disconnecting it seemed that my battery drained way to fast! I followed this:
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery with clockworkmod and wipe battery stats.
And now after 5 hours with about 20 sms send/received I still have 93% battery, normally it was like 83 or lower by then, so I'm very happy! thanks for posting

[Q] Battery Drain Rate - Is this normal?

Hello, I have just a got an XT1254 for around a week so I am still testing the device. Battery is always my biggest concern for every phone I had and therefore I like droid turbo's big battery.
After I have got the device, I tried to debloat most of the moto/verizon/amazon apps and managed to get only 1%-2% drain during sleep overnight. I haven't installed many apps at this moment, as I am testing how long I can get with minimal usage for one charge. It is now more than 2.5 days after charge and I have 62% left, and I disabled almost all censors. and only turn on data/wireless only when necessary.
My problem is, I still get a, I think, quite fast battery drain when screen on. I am not watching video or playing games, I just use whatsapp or test camera, not even facebook, and I get 1% drain in 2-3 minutes. What I want to ask is, is this normal? Or is there anything I can do to reduce further? I think the screen eats most of the battery, and I used auto brightness, or manually to 10% brightness indoor, with dark wallpaper in launcher already.
I have no plan to root at this moment, but I think the processor speed can be lowered. Is there anything I can tweak about the processor?
Thank you very much for answering!

Thank you and I have tried to read the posts. The google play service doesn't seem to be the problem of my device. The drain during sleep is somewhat acceptable, and anyway I need to keep background data on for play service. My problem is, when screen on, it drains 1% in 2-3 minutes doing simple tasks like whatsapp and camera, and the brightness is already either auto or minimum. And my point is, given the huge battery and nothing serious being done, it still drains more than my previous phone (sony m2 also running kitkat 4.4.4)

You should take a look at the apps you have installed, besides this, I think the drain is pretty normal for a QHD screen. Remember there are great number of pixels to move in this screen, so the battery also suffers from this.

I attach a screen capture of my battery screen.
My phone is new and I haven't installed many things. Just nova launcher plus some widgets. BTW, may I ask whether phone idle contribute 25% of power is normal. Yes I mostly leave the phone standby and actually do not have real use except phone, sms and whatsapp.

I don't see anything wrong with the drain, all is perfectly normal. Phone idle is on top when you don't use the phone, so I think you have no problems at all.

Question Battery life not as expected

So i got my S21 Ultra a couple of weeks ago and the battery life isn't as good as people tell it to be... I wonder if this is normal or i have a faulty unit
Important: i am running the latest update on my exynos device (february security patch as of the making of this thread)
What do you expect? You have used the phone almost 12 hours, used Samsung Music for nearly 8 hours and still have 78% battery left lol. This is great.

The SoT is pretty crap i can only get 5 to 6 hours if i'm lucky, all i do is watch youtube and netflix and nothing else pretty much, and since SoT is pretty important to me idk if i should wait for an update or get another unit
If you are comparing to a Chinese phone, I would agree that the battery life is not great. Before buying S21 Ultra(exynos), I was using Mi 10T pro. It has better battery performance than S21 Ultra. The other thing that I dislike about would be the heat issue on S21 Ultra. Its horrible.
SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...
You're also using a high end processor and a large screen with a high refresh rate, it's going to use more juice than a mid range or low end phone. If you send that phone back, someone else is going to be very happy when they get it as their replacement

SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...

With my s21 ultta i can easily achieve 10-12hours of sot with browsjng and youtube on wlan with total runtime of 48hours.on mobile data its a good 35% less (also cause of brighter screen outdoors) but Overall its good battery life for me (note im debloated and using Samsung browser with darkmode!!)
I'm doing OK on the battery. Turned off goggle discover on side screen has helped aswell as 5g disabled as I don't have it where I live atm

Yes if you want the same smoothness and a good 10% better battery you can use the 96hz mod
Put brightness on manual. The display eats a lot of the battery. Try to keep it at 50% or less.
Turn off all animations and use dark mode/dark wallpapers. Junk like tic-tok, fb don't help.

Fb is malware, I don't care who or what's on it, it's off limits. Instagram... no way.
Tweeter just as bad as fb. Full boycott on all that junk until they f-f-fade away
Been using manual brightness control for over a year on my 10+. Occasionally I toggle it on but rarely. Going full brightness will greatly reduce OLEDs finite lifespan. Blue goes first... and the burnout isn't even. If I can get 5 years with just a battery change or two, I want it.
So far between Samsung's and Android's weak offerings I have zero incentive to upgrade hardware or firmware

Yes but if you are using them in tge browser they cant suck your battery up and im only using them for roughly 10minutes a day so no problem. But youre right they are like malware... Traking your location every few minutes and that ****

I do 20-30% charges throughout the day.
Crap like Twitter and fb can cost you your job as well as privacy leading you open to attacks of all kinds. Zero rewards and lots of risk. No.
Remember the night of the long knives?
Think how much easier it be to do now...
Has there been testing on the battery effect of different wireless network modes, including while being connected to Wi-Fi?
I understand that 5G uses more battery, but I'm curious how that is affected when you remain connected to Wi-Fi for all data transfers (using 5G just for calls and texts).
Same question for the other network modes, like LTE/3G/2G vs LTE/2G etc. Or also when you are not connected to Wi-Fi.
I can't help worry that some people are getting bad battery life because they have a poor network signal?
Only rough but very little difference between 4g and WiFi when still, and that's in a location with 2 bars signal. Seems like the phone sleeps better with mobile data on.
It's hard to make a direct comparison with WiFi Vs network, as a lot of the network drain is when moving and polling for new antenna. When looking at signal strength, 4g/5g have the same dBm and 3g/2g have the same dBm, but 4g needs less dBm for a higher transfer rate than 3g, so may use less power over time.
Also I don't think 5g is inherently more power hungry than 4g (I may be wrong), again it's just less available and shorter radio waves, and until now 5g has relied on external modems.
Exactly, I wonder if our S21 Ultra is much better with battery life on 5G, because our SoC includes the 5G modem and it's not external?
My desire is to just keep my phone on 5G while I'm at home idle and the phone is connected to home Wi-Fi. I wonder if there is a battery savings to be had if I switch to LTE while I'm at home on Wi-Fi and the phone is just idle.

General Battery life and optimization

During intensive initial days I get 4-5 SOT and 12h use time. This is with mid heavy usage.
My battery starts today attached:
- over 7h music streaming partially on Chromecast partially bt
- over 1h YouTube (45min in browser)
- 40min Teams video call
- over 30min photos and videos in two camera apps
- 1h of Opera browsing
- Gmail, messenger, maps and all other apps in constant synchronization
- last.fm and pebble running in background
From the list you can clearly see that the only stand behavior is connected to AOD which was over 1%/h so I have disabled it.
Hello
As I understand in my daily use, mixed WiFi - 4g, you can reach 5h.30min ost. Maybe is necessary some adjustments on 4g/5g modem, it sucks a little bit of battery WiFi is the best, the graph is linear.
Attached my mixed 4g/WiFi experience, during today. I forgot kill YouTube, I did 2hr screen total. As you can see in WiFi the graph is linear (untill the middle), while on 4g (2nd half), the curve began to drop more steeply.
Starting to learn how to use this phone.
No complains at all. Can't kill the battery in one day. Most of the screen time is at evenings at lower brightness but I do work so it's my natural usage.
After disabling always on screen, 5G, Google tracking and backup I easily get over 6h SOT and less than 40% battery drain during 24h.
Battery is very good and there's no doubt about it.
I get about 3.5h SOT for 80% battery, no 5g, no AOS, dynamic mode, screen 90hz, no gaming, no apps with heavy drain
I lost 3% over 9 hours last night while the phone was on my bedside table,this was the first night,i think the phone is deep sleeping properly?i have restricted quite alot of apps from running in background

7.5+ hours of SOT is possible. Here I reach 7 hours and 13 minutes of SOT from 90% to 8%. Ultra durable mode, no 5G, no mobile data always active in developer options, all WiFi, and Facebook services disabled. Brightness is set to auto.
To those who's looking for compact phone, superb performance, 120hz display, great speaker, and good battery life, go on with Zenfone 8. Here's my SOT on my Zenfone 8 with force 90hz enabled. Cheers
It looks like the last update improves the battery life quite a bit. Only free hours so no hard claims but the impression is heavy.

The one I got today: 30.11.51.67
I have updated the phone at 70% and got brilliant times afterwards. Over 5:15h SOT and 15h since charged with 20% still left.

Could you please tell me how is the standby drain? Is it more than 1%/h during the night sleep?

I get between 1,3 - 1,8 percent during night in deep sleep. Confirmed by AccuBattery.

thank you for the reply, but could you be more specific? the drain you mentioned is per hour or per entire night?
It's per hour.
You can get probably less when switching off connection of data. I am leaving the phone fully ready as I have used it during the day - just put in ultra durable mode.
Jusr for info, after watching a teardown video I realized he battery is actually 3835mah not 4000 !
