Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.

That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.

I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.

Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.

Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though

No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air

I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity

Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.

most smartphones ned to be charged every day, what battery life are you expecting to get ?

battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.

Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.

+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.

try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.

Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...

My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day
and more...

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.

Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE

I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.

Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....

Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.

[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!

Besides, you should know that KitKat stand by time is horrible. I passed from around 10% battery drain overnight to around 2% with Lollipop. You need root to tweak the processor.

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.

Mi 9 lite battery drain \ cpu usage miui 11

Hi everyone,
I received my phone a week ago.
After first boot it updated to miui 11.
I noticed a day later that the battery is getting empty fast. Much faster than my old redmi 4x.
I figured out that the CPU usage is never under 19% @ 595mhz
I testet that with different apps that show the CPU usage.
In case of that the phone also never get into deepsleep and the battery drains and drains...
Is here someone who can help me please?!

Sounds great! But how can i go back to 10?

First put phone into fastboot mode, then check antirool feature with command fastboot getvar anti if you have
anti: 1 it's all good, after that you need to download from Miui page proper recovery rom, put zip on your phone storage and then flash via Miui system update in settings. Don't flash wrong rom it can hard brick device if you have locked bootloader, also remove password for screen, fingerprints, all accounts, miui cloud

Thanks for that! I´ve downgraded to MIUI 10. But the CPU usage is still never under 19% . If the battery now will drain not as fast as before i will see., but i think it will be near the same.
Maybe you can do me a favor and check with the app " CPU / GPU meter & Notification " if your CPU is going under 19% usage. Maybe it is a issue with this kind of apps....

Probably apps have problem with readings..

I think below 19% when device in deep sleep or battery saving mode. Dont know about that app, maybe just reading in relatime. There is a case when i like your case, at first day using miui 11 stable eu, i can get 2days with 6h sot, most of it using wifi. Then i setup my phone completely. On next day, the battery getting drain fast, and it cant last for 1 day, and just 5h sot. Next i check battery usage, and whatsapp at the top rank. And i unlocking every task. The next day my battery back to normal. And when im writing this post, my battery have 85%, 2h sot, and 7h ago since last charge.

Miui 10 with airplane mode enabled

Since I upgraded to MIUI 11 the battery drains fast

not much draining for me but never go deep sleep, most used frequency is 576 mhz

Hi everyone,
I have the same sad issue.... changed from a 3 years old Redmi Note 4 to a 9 lite.
Battery life with my old Note 4 (same 4000mah) was twice the battery life on my 9 lite, after 3 years!!
I disabled everything in 9 lite, NFC, wifi, bluetooth, background and startup apps, animations, notifications, Gplay updates, face unlocking, always on display, enabled dark theme etc etc....
Same battery drain, 12-13% Android System usage on battery stats.
I hope it will be fixed on a newer MIUI update, but it is very irritating to have to charge a new phone every day, when on an older you had a double battery life.
Please update us in case we'll found a workaround....
Just a question.... How do you monitor CPU usage? I see the setting inside developer options has been removed.....

Same here. Tried many things. Looks like "Settings -> Battery and performance -> Battery saver" solved problem for me. Used to drain ~30% over night while idle, now ~7% in same case.

I suppose battery saving tries to shutdown functions I already disabled...
I tried to leave a feedback to Xiaomi.
Also I created android commands local file dump with code *#*#284#*#* and trying to investigate by myself...

I tried modify modify some settings and uninstall or disable some not used apps before. It made almost any difference.
Previously I used Samsung smartphone. With similar settings I had great battery life. It seems mi 9 lite just cannot sleep/deep sleep without Battery saver turned on. I did not notice any difference in performance, user experience or notification frequency while this setting is on, and it seems it works in different way compared to Samsung implementation. Just give it a try.

May be I'm out ; when I sleep if my screen is " up " I lost 25- 30 % of battery : ( when my screen is "return" 4 or 5 % : )

Interesting.... I'll try....

I find it crazy how this phones loses 7-10% overnight while my RN5 lost maybe 2. I work and live in area with bad 4G but decent 3G signal. I try to force 3G when I can.
I just switched on battery saver to see if it helps my standby drain at all.
I'm currently at 1.5 days off the charger, with 37% battery left after 4 hours of screen time. I am a fairly light user and just browse Reddit, XDA, text, hangouts, and 2 email accounts. Reminds me of my Nexus 5 lol. So terrible considering I do so many things to try to squeeze as much battery life as I can.
Maybe my Galaxy Watch being constantly connected has something to do with it.
Top 4 battery users are :
Android system 20%
Phone Idle 12.7%
Cell standby 12.5%
Screen 9.8%

Have you tried a GSI? Does anything stop working, like finger print reader, etc?

Inserting code ##4636#*#* and accessing networks menu, I found that in both SIM1 and SIM2 is set as default (LTE/TD-SCDMA/UMTS if you have 2 SIM and you use Dual 4G, LTE/TD-SCDMA/UMTS on SIM1 and TD-SCDMA/UMTS if you have 2 SIM and don't you use Dual 4G as default), the chinese network TD-SCDMA (before or after LTE network)
Probably this cause waste of time, battery loss and an higher sar level, mostly when LTE network coverage is not at its best.
Unfortunately this setting can be modified inside this menu (setting for example LTE/WCDMA), but this is lot when you restart the phone.
My firmware version is PFCEUXM european Rom.
I wish this TD-SCDMA chinese network will be definitively removed in next rom upgrade!!!

Android 10 One UI 2 Battery and Performance

Mine is snappier and battery life is better.

The battery life is slightly increased and rest every thing is okay.
Was a beta user. Exynos variant. Im sure the battery life and performance of Snapdragon variants would go more better. Exynos always sucks.

I think battery is better, lets see the rest

Mine is about the same. In the beta forums it seems to be all over the place though, some are happy, some not so much.

Any changes in the camera quality ?

My Exynos S10 used to reach 30-40+ hours of battery time on P (mostly web whatsapp and regular phone calls, no games at all, see pic).
After upgrading to stable Q, juice can't even give me 30 hours. As I see it, in my case Q is clearly the culprit.
SOT is not a valid metric for me, as I'm always on web whatsapp -- lots of use, no screen on.

Stable version of Q. Better battery for me

2 hours of screen
It takes me 2 hours of screen. plz heeelp

For starters, try and disable the following settings, case they are on:
. location
. bluetooth
. AOD
. NFC
. WiFi (case mobile data is suitable for you)
<Display>:
. set screen brightness to something around 50% (middle of the bar).
. set <Screen timeout> to , say, 30 seconds.
. set <Screen saver> to "none"
<Device care> / <Battery>:
. set <Power Mode> to "optimized"
. set <Adaptive power saving> to "on".
As for apps, Facebook is known to be a huge juice drainer.
Let me know how this works for you,
Cheers

Disabling everything isn't the solution.... Something must have gone wrong during the update process. I have everything on and I have a great battery life. Maybe trying a factory reset for example (even if it's annoying)

battery is marginally better on mine, after the update i entered the stock recovery and wiped cache, i dont know if that does anything.One UI 2 is very underwhelming, not many changes

Disabling everything is for quick diagnosing purposes, for identifying shady component(s), not meant to be a solution. Think of a box that won't start. You start by ruling out PSU, then memory modules, video card, and so on. Sure, in the OP case update issues must be considered, as well as third party software.

My phone feels great after the update. Fast and smooth, the battery is the same, gets me through the day with Wi-Fi,BT and mobile data on all the time.
Love the new animations but the gesture navigation needs improvement, especially when switching between apps. Overall great update.
Thanks you Samsung!

ram usage increased too...

I agreed. I'm on the stable version of android 10. I have a Galaxy S10 G973U and It is on T-Mobile. Battery Life has steadily gotten worse for me starting from the October security update and it is much worse on One ui 2.0. Overnight, I lost 15 PERCENT CHARGE. I don't know what to do. I'm not sure if its a problem with my device or a widespread issue and just a problem with the software. Pls help. I called samsung to report this 3 times and they referred me to a repair shop. I don't want to go to the shop unless I am hundred percent sure that this is an issue only with my phone. g973u1 users are reporting excellent battery life and some g973u users are reporting bad battery life. Pls help.

In only 2h of screen time, I've lost 40% of my battery and I was a 100%.
Few web browsing and some texts and Spotify playlist in the background.
Is there anyway to optimize the battery life on One ui 2.0?

Gotta love these "how's the battery life?" threads.
Mine is better.
Mine is worse.
Mine is about the same
Camera quality decreased
Phone runs hotter
Uses more ram
It ruined my marriage
The phone got bigger for some reason
And so forth...

For me its about the same

Hi. as I get the view of the battery life as it was in android 9¡? While still not understand view of the battery life in android 10
