Pretty good battery life!

I'm seeing a lot of posts about poor battery life but am i the only one who's getting pretty damn good results?
I'm currently on 2days, 18hours, 31minutes and 41seconds on battery* and it's still on 31%. I reckon i can still probably get another 24 hours out of it.
Is anyone else getting similar results?
* Roughly: 5 phone calls, 20+ texts, 40+ minutes of youtube via HDMI out, 5 photo's (some with flash) and internet/market browsing here and there.
I'm running CM7 with vorkKernel (standard clock speed) with GPS turned off and WiFi on (when at home),

that kernal you are using. does it show accurate battery stats? I noticed cm7's battery is pretty erratic.
btw this is xthedarknight99 on twitter!

My battery life is great when I use JuiceDefender and when I don't use apps that use the mobile data connection the entire time.
My battery gets raped to hell and back when I have apps running that use mobile data, like MSN or IRC. I work 4-hour shifts and during a shift I usually leave MSN running using 2G data. In those 4 hours I lose around 40-50% of my battery, it's wicked.
One thing I've noticed is, when I enable Wi-fi and leave it enabled, battery drain overnight is around 8%. When I disable Wi-fi AND Mobile data and let JuiceDefender enable mobile data for a short time every 15 mins, my battery drain overnight is around 10%. If I leave mobile data enabled the entire time my battery loses 30% overnight.
Something is seriously wrong with the mobile data chip/driver.

Yeah, Wifi uses a lot less power than 3G when it's connected but uses a hell of a lot of power if it's constantly scanning and can't connect. I always turn mine on when i get home and turn it off when i leave the house

Noticed the same thing too. But less acutely, as I don't use any apps that use data constantly, except for an hourly email check.
Similarly, wifi at home seems to have slower drain than 3G mode when I am outdoors (wifi switched off when outdoors). I don't use 2G mode.
Generally, I stay above 50% battery level after a whole day's use - so I can't complain too much.

Finally plugged my phone in lol
Not got a screenshot of it but the stats are: 3days, 6hours, 17minutes and 49seconds on battery. Not bad!

Mine did something "bad" like this too. 3d 5h... never imagined, after the problems it makes day to day...

You lucky bugger! Ive actually had time to test it in the wild(slightly) today and well its not good at all!
5hours 20minutes or something around that, phone actually drained 99% lol! In that time i did:
almost 2 hours of browsing web, forums like hexus/xda so nothing to heavy... no constant loads/refreshes
Played 10-15minutes of xconstructor (im so easily pleased!)
Had 2 gmail accounts of auto sync, push basically
made around 27minutes worth of phone calls
5 texts
Not much really to drain 100% battery . Any ideas on how to improve battery life?
edit: this is on modaco fr18b2

@meltus.... do you mind me asking whether you're on stock rom or what apps etc you have changed to get that. I'm getting a healthy 24 hours for the battery normally but wouldnt mind extending that!!

Did you try to recalibrate the bettery with batterycalibration app? For me it basically doubled the battery life!

i recalibrated the battery before installing a new rom (it was 100% battery) however ill try again .

Meltus do you have sync on?
Also do you use whatsapp?
Those are the #1 battery killers on my phone.
Specially whatsapp.

I can't understand how your battery can last so long, while mine last less than a day ...!!!

That is impressive
May I know which nightly build are you on?
I've always been tempted to install them but i was too afraid of stability issues

that is indeed impressive. my battery gets merked by approximately 33% after 40 minutes of youtube lol

I have almost the same battery life on the latest CM kang, but with 2G only... With 3G I get little more than one day...

I think he's pulling our leg with that screenshot
No details of rom, baseband or ril combo etc.

I lost 3 or 4% in one hour on standby with Modaco fr18b2. Now on CM7 kang I have still 100% after 8 hours on standby. Data-2G and Wi-Fi are turned on all the time.
Well settings are the same as with Modaco ROM.

I want to flash CM so bad but am waiting to see what the official gingerbread does.. I know that once I go to CM I won't go back lol my battery is horrible right now

Huawei p9 screen on time

Can you guys post some screenshots what sot sre you getting?

Don't have a screenshot but I know I got +6.5hrs yesterday. I'll post a pic when battery runs down again. Still on MM.

In my opinion, P9 has pretty good Screen-On time.
Here is my average Screen-On time since 30th January 2017.

Have you been using the phone with full brightness?
In this battery test video, P9 with full screen brightness will last about 3 hours and 37 minutes.
In another video, a guy get 6 hours and 8 minutes out of his P9 from his normal usage pattern.
Most of the time, I would either be indoor or in my car. So, I think auto-brightness does not have to frequently increase screen brightness. That is probably the main reason why my screen-on time is good.
I also have an adblocker installed. Because Ad delivery system consumes a lot of battery.
This is an old article from 2012, but I believe it might still be true even today.
One example from their research, Out of 100% battery that Angry Bird app had used, only 30% was used by the game itself. The remaining 70% of battery consumption was used by tasks related to in-app advertisements.
If your phone is rooted, you can use Adaway.
If not, DNS66 is an adblocker that does not require root privilege.
Moreover, I mainly use my phone for communication (through Instant Messaging, E-mail, or web browser) and map. I do not have any 3D games installed. The most power intensive app I have installed is probably is Solitaire: Decked Out.
Additionally, some common causes of high battery usage are
- Proximity to cell tower. If you usually are in areas with bad reception, your phone will use more battery in order to connect to cell tower. Many areas have different signal strength for 2G, 3G and 4G LTE networks. Unless you really need to use high speed data, you can save battery by switching to networks that have the best reception.
- Wi-Fi consumes less battery than mobile data (3G, 4G LTE). Sometime people forget to turn Wi-Fi on. So make sure that you use Wi-Fi as often as you could.

Thank you soo much!!! Is there any way you can post some screenshots of your home screen just to see what other people have?

Difficult for me to give you an accurate SOT because I never charge my battery above 80ish % I never charge to 100% as it stresses the battery too much but I'm delighted with my SOT always use auto brightness. Coming from a 2 year old Note 4 the P9 SOT is outstanding!

Do you mind to share which firmware you are using right now? Recently I have upgraded my firmware and the battery life has deteriorated.

Poor battery performance, what to do?

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

Thanks!

you might have some apps draining battery. I'm used to a rooted phone, so I'd always check with wakelock detector, but I'm not sure what you can do without installing an app as a system app.
Try factory resetting your phone and using it without installing anything for a day and see what the battery life is like. If it's significantly better, install your apps 1 by 1 until you find out which one is causing unnecessary cpu cycles or wakelocks.

But I wonder, I shouldn't see the heavy usage on the battery info page? Like which app does most of the usage and time spend in the background or CPU?

I had excessive battery drain, about 10-11% an hour with every off . A full factory reset cured the problem.

What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

You won't always see this as it could be a byproduct causing a kernel wakelock.
Either way, something is acting incorrectly. The only way to really figure it out is to start over and try things slowly till you find out what it is.
For instance, on my nvidia shield tablet k-1, I was getting horrendous battery life on every single rom, stock or AOSP/Lineage. I found that I was getting 30% wakelock killing ~20% battery life per day when it should be sub 5%. I found that wifi was causing these kernel wakelocks and setting wifi to be disabled with the screen off unless charging fixed the issue entirely.
Now, that anecdote likely has nothing to do with what you're experiencing, but note that you can usually find out what's wrong from trial and error.

I've had my note 8 for 6 days now, and battery life is excellent, i mean i have wi-fi and 4g lte on all the time, bluetooth on all the time, sync with 3 emails, Facebook, weather widget, weather screen refresh every 30mins, location high accuracy, edge lighting, aod schedule 7pm-7am, was 100% at 6am, played games on it lots, used the phone 2x, 1 hour call and a 30 mins call, text messages, it's 130pm and I'm at 55%, try a factory reset then log in to your gmail then just try to update the phone if there is any. Then reboot then start installing your apps. If it doesn't work call carrier customer service and complain about the battery not holding up like some people you know who has note 8. They might replace it with a new one.

Phone died 15-20 minutes after I did the screenshots, so a bit more than 2 hours...
So.. yeah.. I will try a factory reset and start install all the apps bit by bit and see which one causes the troubles.. hopefully is nothing more than that.

Did you restore a backup or did you load your apps fresh from the play store?
I've had horrible luck with issues like battery life restoring from backups. I always install apps fresh.

I did a google restore from backup! Damn! And I was thinking that I should maybe to a clean, one by one app install.

My battery life is also not great but im using full resolution and when i remember time when i got S6 edge on launch....the battery was horrible but after few updates it was perfect so stay strong and wait a bit

can you translate "not great" in hours? :laugh: Because I will say that mine is second after horrible.. with update done.
I will start the reset in a short while and I will test it tomorrow with minimum apps installed.. those which I really must have in a working day..

Maximum 5 hrs on wifi normally about 3-4 battery is not great on note yet....some optimalization would be nice

I use Ampere to monitor the instan drain of current. In a quiet situation (screen on, internet or tapatalk browsing, gear connected, wifi and data turned on) you should have something 200 mA drain.

Maybe some of the settings changes you're making are somehow rendering your phone less efficient.
I have the USA unlocked version and use it as it came without changing to a dark theme or turning anything off and the battery life is much better than yours.

I restored from a helium backup. My battery life wasn't good for about a week but it did last all day down to 20-30% at the end of the day. After a week it has improved maybe due to apps updating. Now I'm at 70-80% at the end of the day with moderate use. I have disabled several apps I didn't need as well.

Seems like it's hit or miss with the battery life. I see a lot of people happy and some are having problems. Hopefully Samsung might push a update to help.

Get cpu spy and verify that your devoce is going into deep sleep when off(mine wasnt at first until i froze/removed some rouge apps). Install accubattery and do a benchmark and see how your battery does. At least do 6 discharge cycles first to see an average. Also, in device maintenance, you can make all apps doze when not being used now.. this is a new feature. Add all of your apps and they get put to sleep immediately. I get 8 hours SOT this way

You dont have to use med battery saver either, just read my reply on this thread and you will be good. You may have to experiment a little to get your device to go into deep sleep when screen off. Mine didnt at first. Its on my other comment

I got back from work and my phone was at 75% that's between 9:30am and 6:30 pm. So my battery life is pretty good. I lose about 5% overnight.

I average 7hrs screen time Got 8hrs yesterday

Question SOT is lesss really less

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Show us a screenshot of battery usage when you are at 10% - not at 80% - then we can see where all your battery fuel is going.

Sure its from 2 days ago

Battery is draining extremely fast on Android 12 (BULK) as well...
Is there a way to know if our phones haven't been manufactured by Samsung?
- There is Korea but also Vietnam etc... this might have an impact somehow?

What are you doing on whatsapp....that's a huge drain....

whatsapp is always a huge drain if you use to send and receive messages. My solution to this was enable multi-device login. I, now, use Whatsapp mainly on my computer when I'm at work and then revert to the phone when I'm off. The led to a huge difference. What used 25%+ for whatsapp..now stands at 4-5% over the day.

Morning 7 to 5pm I m using WhatsApp for work. I m using 2 WhatsApp. Work WhatsApp isn't stop every minute always receiving several message. I can't stop WhatsApp because of work. I think that's why WhatsApp percent is so much

whatsapp is always a huge drain if you use to send and receive messages. My solution to this was enable multi-device login. I, now, use Whatsapp mainly on my computer when I'm at work and then revert to the phone when I'm off. The led to a huge difference. What used 25%+ for whatsapp..now stands at 4-5% over the day.

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Does your battery run out by the end of your typical workday? Do you have to charge it during the day everyday, or can you get to the charger comfortably when going to sleep at night? SOT by itself isn't a very good metric when seen in isolation.

Are you mainly on Wi-Fi or mobile network? OP is on a building site so most likely on mobile network most of the day

So your battery level goes to 20% or below by every noon? Sheesh, that is indeed potato battery life...
But your screenshot suggests a pretty good standby time, nearly 11 hours usage and 72% remaining...
Maybe post the battery usage screenshot once your battery dips below 20% so we can try to pinpoint the issue?

Actually my battery level around %50 in noon. For example this screen shot is today after noon. In noon was %100

I am 90% sure that your battery drain is caused by the mediocre 4G signal which is used for internet at all times. A lot of power is basically being allocated to get a better signal and thus while you use WS all the time, your batt drains FAST. If you happen to have Wi-Fi for a day or two and the signal is maxed out, the battery will surely last longer. Generally speaking though, you cannot compare other peoples SOT to yours as most people do not use WS as much as you, nor 4G at all times.
There might be some other extra settings that could be altered to improve battery, like:
adaptive battery ON
enhanced processing OFF
location OFF
background data OFF
resolution to FHD
background usage limit to put rarely used apps to sleep
NFC OFF
nearby device scanning OFF
And of course the last version of android 11, as it seems A12 is not yet worthy or ruling the S21U. Sadly I have a feeling that Samsung might not fix A12 for the S21U as they are now releasing the S22. Hope I'm wrong.

The Big Battery drainers:
Screen - If you have manually set it high - Try Auto
Mobile Signal - Nothing you can do if its poor - unless possibility of WIFI
Location - Always On is a no no if you can help it - try use when app open only.
Background Data - Turn off for apps which its not reqd .
Also Since Android 12 I also seem to get lower SOT although my phone battery has been same since android 11. Im not sure if they changed the way they show/measure SOT now.

Question "Cell Standby" battery drain on latest MIUI Global 13.0.12?

Hi, everyone. I bought a Redmi Note 11 Global a few days back and while setting it up, I was amazed at the battery life. It was at 56% when I opened it up, and throughout the entire setup process and after around 5 or 6 hours of screen on time, I was still at around 15% battery.
After that, I decided to update the phone, and immediately after, I realized the battery life I was getting wasn't as good as it was a literal day ago. From 90 to 50, I would only get around 3 hours of SOT and from 50 to 10 around 3-4 hours. My use case was even lighter than in the first day, yet my battery life had dropped significantly.
I went into phone settings and for some reason, Cell Standby, Phone Services and Phone idle were in the top of the list, Cell Standby taking up the most of the battery. I have no idea why this is happening. I've tried "Reset Wi-Fi, mobile networks, and Bluetooth", clearing Play Store and Play Services data, turning off "Always keep mobile data on" and the battery life is still pretty bad.
This is my first time on MIUI, and I am absolutely disappointed. Despite the whole battery issues, MIUI has a lot of other accessibility issues that stock Android doesn't have.
Does anyone else have the same problems on their Redmi Note 11? Has anyone had a good fix for it? Please help.

Mine working perfectly, maybe your device's hardware error?

I thought about that, but this is only happening after the latest update. It was fine when I bought the phone.

Disable make calls with Wi-Fi option at settings.

Factory Restoration may work in your case just an opinion

I'll try this. Can you let me know your SOT on a full charge down to low charge?

I will try that as a last resort. If you don't mind me asking, what SOT do you get on your device?

I never checked SOT time but Cell Standby uses about %1 battery. It was high before disabling make calls with Wi-Fi. I'm using Xiaomi 11T.

I can't find that option. Can you name the exact name as it is in settings? Btw I use the Google Phone app and not the Xiaomi phone, although Phone Services still uses a lot.
Edit: I just realized my phone doesn't have the Make calls with Wi-fi option, and not VOLTE either. My country doesn't really use it.

No like what's the Screen time you get on a full charge.

I've tried resetting the phone now too. It didn't work. Cell standby is still at the top of the list by a large margin. Do you think this is a hardware issue or a miui issue? I can't really say since no one here is telling me their SOT so I can't say if this is a me problem.

8+ hours from 100-0 or some other percentage? Also, I have a friend who also has a Redmi Note 11 Global, and I saw his Battery tab and Cell Standby was at the top of his list too. I believe this is an issue with the update but I can't tell.

From 100%, this is an estimate but actual time maybe more than 8 hours

Hello I'm not sure if it will help, i'm on Mi Mix 4 and i had this issue for like 2 weeks now, finally i did something which solved the issue for me, i'm on MIUI 13.0.6 EU rom.
steps i did
1. Go to Google Play store
2. Search for an app called "carrier services"
3. Uninstalled it, so it reset to factory default.
5. In less than 6 hours cell standby completely disappeared from the battery graph.
I used to have more than 70% eaten by cell standby
this is the app, below is 10 minutes after i uninstalled it, battery drain from cell standby went down from 70 to 49

Tried this - did not work for me. RN10 Pro EEA MIUI 13.0.12

I have this issue on Mi 10T Pro MIUI 13. Battery drains overnight but if I switch on airplane mode even with wifi, Bluetooth and location on (VoWifi enabled too), there is no such drain. Apparently factory reset didn't help unless I've already did something wrong again.

I have a RN10 Pro and a RN9 Pro EEA
Since new, both phones have annoyingly had "cell standby" at the top of the list of battery usage.
The RN9 Pro recently updated to MIUI 13.0.1 I did a factory reset as a matter of course because of the change from Android 11 to 12.
I have no idea what Xiaomi did with this update, but I am delighted that "cell standby" is now at the bottom of the list of battery usage and "phone idle" is at the top - which is where it should be for my usage of the phone.

Update: There is one change I noticed that the MIUI update has made in the version that is fixed. They changed my APN access points to something completely different for my SIM (Vodafone UK). Unfortunatley the default APN's are locked on the RN10P so I cannot change them to test. Adding a new APN does not fix the problem.
