[Q] Note Battery drain? Rate Your battery Life!O_o?

Hello,
im thinking on buying the Note =]
i wanted to ask "heavy","excessive" users how is the phone battery drain ?>
*how long your phone lasts without charge (excessive,heavy use)?
*how long your phone lasts without charge (normal use)?

Im only use any of my smartphones with excessive,heavy use.
I have only 2 full battery circles and im using stock root rom/kernel.
All my phones was with very good custom kernels and lower voltages cause i wanted to stay alive during the day (8-23:00).
Now,my battery keep up the day but more easy than my previous phones (you can see which in my sign).
So, even my battery is new with few full circles, even im not using custom kernel for uc or uv, its better than my previous smartphones.

For a 5.3" display the battery life is exceeding expectations.. Based on my usage it has more battery life than the Galaxy S2 altho movie time is still the same at 8:30hrs to 9:00

I think it's very hard to define excessive vs normal use. Also the usage patterns of different people varies greatly. mostly because some use wifi on 100% of the time, others just turn it on here and there to check emails. Same for background sync and autosync which are battery drainers . So it's really hard to compare...
I keep my Wifi constantly on, background sync on, autosync is off but I have a task in Tasker to autosync every three hours manually. I have some push emails in K9 and twitter, gtalk and tapatalk syncing.
So on a day of super heavy usage the phone will last about 16-17 hours (ofcourse that includes about 7 hours of sleep time). With normal to moderate use I can make about 24-27 hours.

Hi people! I'm noob here! (wanted to write new but couldn't resist!)
I recently bought the Note and been having a few hard times with a couple of things.
One of the specifics concern battery life. Having been showered in the awesomeness of a 2,5 ma battery i thought the battery would be invulnerable but i was wrong.
The first 4 days the battery lasted me quite fine having to charge the phone once every two days. Heavy consumption was done for brief periods of 1-1:30 hours where i would try to shape my phone in the image that i wanted.
By the end of the fourth day i had a respectable amount of apps inside but not too many to explain the fact that my battery life now has decreased to 1 day.
I kinda panicked when i noticed the difference and went ahead to install Juice defender and advanced task cleaner apps. What's weird is the fact that before i did i would charge the phone before going to bed at night and then pull the plug when it would be full. By the morning the phone had lost about 25% while inert!
Noticing that i would go to the battery use feature in settings and see that the radio(!) which i hadn't been using was eating away my battery's life along with the screen which was inactive as a consequence of the phone in locked mode and a few other apps which filled the rest of the loss.
I tried to kill apps and i use Juice defender pro in custom advanced mode effectively rendering the phone dead after locking. It still consumes the same percentage of battery although now it blames the radio less and the live wallpaper more.
Am i to assume that my battery has reached it's "puberty" and that's "normal" from now on or is there a problem i just can't diagnose due to lack of experience?
This phone is my first android device. I do not know my way around it although i am learning more and more in a rapid learning curve.
Please note anything you might think has escaped my attention.
Thank you.

Your question is a little OT but i'll try to answer real quick.
25% loss of battery sounds about right if you have your Auto Sync ON.
Disable it and you'll go down to about 10% a night. Am i right or am i totally off here ?

I'll try it and see tonight. Thanks mfractal. Having been an IPhone 3G owner i gotta say, it's still kinda disheartening to see that 10% battery loss overnight is considered "normal". Will work my way around purchasing a second backup battery for emergencies.
Thanks again.

i also come from an iphone, and yeah, you have to make some adjustments.
you can take that drain to 1-2% if you disable Background Sync.

this was my batteries first full cycle. but you should get a general idea of how it performed.

this was what i would consider 'heavy' use, atleast by my standards. Edge only, Auto sync on, brightness at 75%, fairly frequent use.

Draining twice as fast after an update on apps this morning!
Hmmm, I have been using the Note for about 2 weeks now. With Juice Defender installed (with aggressive settings), I get by OK with the battery for a full day.
Well, that was until this morning when I ran an update of a few apps, and now I barely got to noon when the battery went completely drained. Same settings on Juice Defender.
Any clues on how to deal with this? I am thinking of reverting all the updates to double check.

guys, the steps to analyze battery drain are quite standard.
Download BetterBatteryStats (there's full version for free for XDA users, search the forum)
Download CPU Spy
Charge to 100%, reset statistics in CPU Spy and let the battery drain to 10-20%.
Then Analyze wakelocks in BetterBatteryStats and you will see which programs keep your phone awake.
If you want to make sure the phone is entering sleep mode and staying there, reset cpu spy stats before going to sleep and check in the morning. more than 90% of the time the phone should be in deep sleep. If not - again, betterbatterystats's wakelocks will show you what's keeping the phone awake.

sure NP.
problem is that background sync is required by quite a lot of programs to function correctly. Hell, market won't even open with it disabled.

My battery life is pretty good atm considering its still a new toy and gets a heavy workout.
The battery life will improve over time as my usage will drop but with the screen it pretty much can replace my pc for any basic web stuff outside off the heavy duty work only a high spec PC is good for.

Disabling background sync defeats the purpose of having a smart phone, no?

I do like my phone and the screen real estate, and understand that, it can be major battery hog. But I would really like it to be super efficient when the screen is off.
I was looking at my battery drain graphs, (Settings>About Phone>battery usage) and noticed that my phone is active almost all through the night, (even when the screen is off).
So i loose 25-30 overnight, on IDLE.
Is this normal?
I'm using Exchange instead of the Gmail app for my mail. Does that use more battery?
Regards

Of course gmail use more battery like every app running in background and syncing.
But your battery drain overnight is really so much.
The normal is 1% per hour without any app syncing in background and about 2% or 3% with background syncing apps.So you must check your apps.Something draining your battery.
Overall,i don't believe that note battery isn't good.i think Samsung haven't done so good work in filmwares and apps.
I have removed the most of Samsung apps and my battery is great.
Maybe a update from Samsung solved battery issue.In nexus previous days released a filmware update which change amazing the battery life.users mention that they loose 2% overnight.And before this update nexus battery sucks!
So, we must pray for something similar in our note from Samsung...
Sent from the best smartphone, Galaxy Note...

Do you have auto sync on? If so please turn it off and watch the drain overnight drop to about 10%
If not then we got a problem

I got my Note two weeks ago and am since struggling with my battery usage as well.
It's hard to reproduce, but Android OS is the reason for excessive battery usage when the phone is idle.
Today I found this quite interesting. Please have a look at this screenshot:
Since a few days ago I'm using Llama to control some settings on my phone, but the drainage was present before I installed Llama.
When you look at the first gap in WiFi usage you can see the phone disconnecting from my WiFi router at home (TP-Link TL-WR1043ND) when Llama disabled my WiFi.
About 20 minutes later, when I arrived at the office, Llama reactivates WiFi and my phone connects to our WiFi access point at the office (TP-Link TL-WA801ND).
At this point Android OS usage goes up considerably and it won't stop, even if I disable the phone's WiFi.
Actually at the second, larger gap in WiFi usage I disabled the WiFi connection manually which caused my phone to stay awake until I activate WiFi again.
Edit: Using Titanium Backup I have frozen Wifi-Sharing and the Wifi Manager.
Apart from that, Wifi usage was never an issue on my old Milestone, where I had Wifi enabled permanently and the battery lasted for 4-5 days.
I'd be glad to provide more information if that could help figure out the cause of AOS's battery usage.
My phone is currently running:
PDA: N7000XXKK9
PHONE: N7000XXKK5
CSC: N7000OXAKK9
I installed FM-Kernel 1.4, hoping it would fix this issue. It did for a day or so...
Apart from the kernel it's the newest 2.3.6 stock ROM I received via FOTA though.

I easily get a good day out of mine with quite a bit of use. If use mine lightly I can get 2 days out of mine. If you are in need of urgent 3G switch 3G off to GSM to conserve battery life.

Sorry, I forgot to include it in my post.
Since I got the phone I have it set to 2G only, because I used up my monthly quota and am getting throttled to GPRS speeds anyway. So the 3G connection isn't the issue either.
Apart from that this happens in flight mode as well.

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

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.

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

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.

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 !

Question What is your standby battery drain rate?

The lowest I've been able to get it down to is like 0.7%/hour.

On my old mate 10 pro i was consistently 0.3-0.5% per hour but with the S21 Ultra im consistently 3-4% per hour and i have all the same apps installed and same usage patterns, first phone ive ever owned where i need to put the phone on aeroplane mode a few hours a day just to get me through to bedtime, even on aeroplane mode i cant get it under 1% per hour definitely wont be staying with Samsung after my contract runs out, they dont give a toss about battery life

According to GSam Battery monitor : 2.3% per hour

adamlee2012 said:
Are you moving around a lot with phone in pocket? Airplane mode doesn't solve the camera service wakelock while it's moving it activates auto focus to prevent camera shake, it's a common drain and Samsung say it's working so they won't fix it. We've started a petition and need as many people as possible to sign it. Temporary solution is to turn sensors off.

yes im an extremely active person who walks between 10-20k steps a day according to Samsung health, im fully aware of this wakelock and have signed the petition, i done a city break in Dublin with someone who had a 5 year old Huawei the other week and it outlasted my S21Ultra, quite frankly its embarrassing for Samsung, i have the Samsung upgrade program and i did plan to get the new Ultra every year but because of the battery life there is no way im remaining with Samsung after my contract expires, yes the camera, performance, screen and UI is in my opinion the best out there but its all pretty pointless if the battery can only last 12hrs or so when on the move

At night time I'm registering the same 0.3%/hr as with the old Mate 20 pro, but that's with Wi-Fi off and power saving mode.
Mind you, that's not exactly stellar considering the 20% battery size difference and the 5nm vs 7nm process.
During the day it varies too much depending on how many emails I get - even when in standby, but 0.5-1%/hr on a good day.
All taken from Accubattery, same as with previous phones.
BTW...it's embarrassing, but I turned off Google Fit tracking and resort to a smart watch for step and activities tracking...it was indeed burning the battery quite fast.

Xiaomi Redmi Note 10S Review: Cheap Android smartphone is water- and dust-proof
We review the Xiaomi Redmi Note 10S with the MediaTek Helio G95, ARM Mali-G76 MP4, 6 GB of RAM and 128 GB of internal storage.
www.notebookcheck.net

The battery is ok, but, I have a standby drain of about 25% overnight in a 6 to 7 hrs period!, wifi on, syncing just gmail in one account, dark mode on, no screen lighting upon notifications, bluetooth off, location off, haptic on, brightness at 40%, good operator signal on 3G, this iw driving me crazy! I had a galaxy note 10+ exynos (that I gave to my son) that drained less than 1% per hour at idle, and syncing everything, max resolution, running in performnace mode, etc, I just do not undersatand why this redmi note 10 eats battery like crazy, despite hqving lower specs than the galaxy note10+, but, in the end, you get what you pay for, no more, and most of the times, even less…

To figure out the culprit behind such phantom battery drains I find installing GSam Battery Monitor helpful.
Install it and let it run for a few charge discharge cycles and post screenshots to see actual usage vs standby drain

Looks like you brought it from 17% - 25% overnight drain down to 1% after optimizing your device? Try GSam
winoles said:
I have this device since August 27th, after setting it up, I started optimizing it, restricted background use for a lot of apps, well, everything that could be disabled or restricted, I only gave free pass to apps I consider important, but, the reults were really bad, 17% of overnight drain! Long story short, the optimization must be done very carefully, trying to stop all kind of things might prove negative, by trial and error, I now get a good battery life, now it barely consumes 1% in 8-9 hrs idling at night, aod off, wifi on, gps on, so, try to optimize your device carefully

Here are some tips to improve standby time by hibernating background apps using the Greenify app
How to Optimize Your Android Phone’s Battery Life with Greenify
At this point, smartphones are prolific. We use them for calls, text messages, social networking, photos, quick searches, streaming music, watching videos…the list goes on. But each thing you do drains your battery life, and some apps will even continue to drain your battery in the background...
www.howtogeek.com

I get around 20 hrs of backup with moderate gaming about 1 hour... Lots of fb youtube.. and also decent standby..
I use dark mode turning of individual apps..(coz it's glitchy).
I use automatic brightness..

auto brightness always on dark mode, sometimes I go two to three days without charging if I don't use much.
When gaming and watching youtube, browsing the web I usually put my phone on charge at around 50-40% battery life late at night and take it off charge either before I go to sleep or when I wake up. I've been VERY happy with my battery life on this device, I've never had any smartphone last this long in my life and it plays the PS2 (AetherSX2 app) games I want to as well, such a great cheap device.
For today my phone has been on for 26 hours and it's at 66% but I didn't use it that much, I played maybe one DB legends match, caught a few pokemon in pokemon go and watched some youtube vids.
I'm on global 12.5.15
edit: 30 minutes later and I am on 65% battery down from 66%
edit: so this morning about 10 hours after my previous edit I put my phone on charge at 51% battery life.

was there an issue with earlier versions of MIUI or something? coz I've only gotten my phone for about two months now and I've never been happier with a phone's battery life

Guys I recently got a Redmi Note 11 and so far battery life has been great, but Cell Standby is draining the most battery. Why? Even though its always connected to Wifi and I'm using only 1 sim card. Never had this issue with my other android phones.

this isn't for the redmi note 11

See attached. Guess those processes are what cause not great idle battery usage for the 10s (maybe ALL mtk g95 devices? ).
Anyone with an idea if
* those can be killed without affecting anything else?
* what exactly is "vendor.mediatek.hardware.pq" doing?
And since its named "pq" is this related to the oversharpening issues?

I couldn't find a thread specifically for Note 11 so I posted here. Its MIUI, its the same whether its 10S or 11, hence I asked.

yeah so basically you can kill pq by deleting one file in /vendor/etc/init, but doing that will result in broken color mode stuff, meaning no reading mode, no saturated mode etc.

So, I had to reformat my 10s after it began acting funny (lots of random reboots, weird behaviour.. )
(PS: never let your phone run down to zero - I've read this somewhere that it causes corruption somewhere and I think this is what happened to mine)
Great timing miui 13 global is available, so now have the reason to upgrade from 12.5
and now... the pq process I saw running all the time eating CPU is gone or at least running sane now, as shown in the screenshot.
Ongoing monitoring of battery but this is a great start, and a great reason to jump to miui 13.

I charge between 20%-80% that means i get 60% of alloted use and i get 5-6 hours SOT on light usage , browsing chrome and watching YouTube(10% charge per 60 minutes basically), when i do heavy activities like emulating ps 2 games (Aethersx2) it drains from 80% to 20% in around 2hours.
