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.

Not sure. The battery stats may be off slightly but it's been well over 2 days since i last charged my phone
here's the screenshot i took a few hours ago.

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

[Q] 3G network and Battery

I need help with this. I have noticed that my phone battery lasts a very short when is on a 3g network, using or not data traffic
To prove this, first i left my phone before going to sleep, on 3G network at 100% and Stamina Mode On, but after 6 hours the battery go down until 82%(6 hours and 37 min sleeping). I made the same experiment but in "Only 2G" mode, and the battery go from 100% to 98%.
Also i've made the same test on 3G network and NO Data connection. Results, 100% to 80% in 7 hrs.

Finally and following the advice of an user from sony support forum, i did a factory reset using PC Companion(12.0.A.2.245). So, no root, no applications, no sync with google, no nothing. I left it at 100% and dropped to 82% in 7hrs on a 3G network without data connection.
Besides, this problem causes the projections of battery life do not change when you turn on Stamina Mode. I mean, Stamina Mode works(disable data connections) but there's no differences between have data or not, the phone uses the same battery.
So it is not normal that battery consumption on a 3g network while the phone is idle. I've made some screenshots and as you can see, the process com.sonyericsson.android.wakeup, has to many wakes. I read about this en xda-forum and is seems to be related whit Fast Dormancy, but not sure if that's the real problem.
I lost the screenshots when i did the factory reset but can see in this thread of Sony Support forum: Sonymobile forum: 3G and Battery Drain
I hope you can help me. Greetings
PS: sorry my bad english

Only thing I can suggest it's leaving WiFi on. This consumes less power when idle.
Really confused by people's problem with the battery, in use its average, but stamina mode works perfectly for me.

The 3G radio can be one of the biggest wasters of power in a phone especially if you are a long way from the cell tower or your local cell is very busy. Even when your local cell is close, when it has a lot of simultaneous connections the signal strength goes down and your phone continually tries to reconnect, in order to remain on the network, using full power.
If you are lucky to live or work near cells which don't get very busy, the 3G radio reduces its power output, and probably also doesn't have to reconnect as often.
Still, your case sounds a bit extreme, so maybe there is something else involved exchanging background data when it shouldn't be.

Thanks for the answer.
I thought the problem was the signal. So I checked the signal strength at the place where I did the tests and the results were that the signal is between -75 dBm and-85dBm. That's a good intensity. Besides I live in a small town, so I doubt that the local cell is very busy.

I think that's because the fast dormancy. Are you root? Try installing betterbatterystats and see what processes are draining your battery. In my case I had to delete de fast dormancy apk and it solved the issue.

Yes, that's one of the first things i do(fast dormancy)...and not solved the problem.
I don't think is related with the battery, because in 2G, the battery works perfectly. The problem is related to the Phone Radio. :crying:

As many of you suggested 3G is another way saying 3 times faster battery drain!
Use wifi unless you are on the go in this case if you have to use 3G

But Wi Fi is useless to make phonecalls. My problem is not related to the traffic data on a 3G network. The problem is the standby in a 3G network without Data and wifi. As you can see in the screenshot below, the phone radio consumes too much battery on stand by mode.

Thats a real problem .... it may be a software issue!

I was a big fan of the battery, but updating my software killed deep sleep. Wiping everything and installing from scratch fixed deep sleep.
3g is a big drainer, but stamina mode should turn 3g off when the device is idle.

Thats the problem, Stamina turn off 3G data connections(internet), but 3G phone radio(calls and sms) keep working and draining battery. So, stamina just give me 2 or 3 more hours of battery, not 4 times more battery as sony promised.
By the way, the specifications of the phone says: Stand-by Up to 635 h (2G) / Up to 734 h (3G)

go to settings>data usage>click three dots of the right top corner and click on the "restrict background data and auto sync" might helped ur problem lil bit.

Yes, I tried that too. But as I said before, the problem is not battery consumption using internet. Is what it consumes wcdma radio to stay connected to the cellular antenna, make calls, or data traffic.
Notice the difference after 7 hours standby:
2G --> 0,1%/Hr
3G --> 2,6%/Hr

I have also having same problem.
Turned off data and wifi. set only WCDMA network, enable stamina mode.
The battery drop from 100 to 84 within 7 hours.
Check the battery usage, the Cell Standby occupied 54% of usage.
Still havent test for 2G. If really 3G problem, then i will just stick with 2G when im sleeping ><
BTW, my galaxy note N7000 battery drop 0%-2% while im sleeping with using 2G network (off data wifi)
*Yea, the battery drop 0% after 7-8 hours

to reduce the number of wakelocks for fast dormancy, root your phone, then go to /system/etc/fast-dormancy and open fd_custm_conf.txt. replace the '0' of the 2 lines with the MCC and MNC numbers of your APN respectively. you can find these numbers under your Access Point Names. just click on the one that is active and scroll down until you see MCC and MNC. once done, save the file and reboot.
it works for me, the wakelocks have decreased but i still get a huge battery drain in standy mode, with wifi on and stamina mode on. hope this fixes the issue for you. cheers :good:

Yeah..i also removed the "Fast Dormancy", and "wake up" disappeared. However, the problem with battery consumption on 3G network continues :crying:
We can only hope that version 4.3 solves the problem. :good:

Sorry to jump onto this thread with a question that doesn't help you solve the battery issues, but I'm guessing you guys will have a good idea of the answer to this.
How do I set 2G only? The only options I have are: 4G (preferred)/3G/2G, 3G only, or 3G (preferred)/2G.

Some firmwares don't let you do that. But you always have the option to do with the information menu. Just dial *#*#4636#*#* and then go to "Phone Information", there's an option to set the network type. :good:

Thanks, I did find that one, but it's a bit too much for my wife to do regularly. Once it's out of warranty, I'll stick a different rom on there. For now, she's getting 2 days, so can manage with that.

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.

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.

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.

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?

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 Pixel 7 Battery Drain in Phone Idle

I've been noticing huge battery drain on my Pixel 7 after the March update. No particular apps are draining the battery, phone idle alone does it.
I thought after the June update, it will make the battery backup better but I think it made it even worse. Last night I charged my phone to 100% and slept by turning off WiFi and mobile data. I even kept my network type to 3G to avoid background activities from 4G. And waking up after 5-6 hrs of sleep, I found my battery to be 89%. Screenshot is attached below. This is very disappointing. I bought this phone on February. It has not been a year and this is the performance I get from a flagship?
Clearly, this is not normal. Phone Idle draining 78%(of the 11% actual battery drain) of my phone's battery is crazy. I used to get 2 days of battery backup before that March update. And now I can hardly survive 16hrs. Please help me with a fix.
Notes:
Country: Bangladesh
I use dual SIM. 1 physical and 1 e-SIM.

Factory reset, then be careful what you install.

You didn't use anything on the device though. The phone is idling more than doing any other task. So of course 78% of that small amount of battery drain is going to be due to the idle because idling is what is doing 78% of the time. I really don't see any issue here. I mean you only lost 11% battery over 4 hours and that first 15% drains quicker because lithium ion battery drain isn't linear. That first 10% always goes faster than the rest of the device. If it really bothers you, I would suggest changing the doze parameters to wear it disables the sensors on the device until it's unlocked.

Also, I just noticed that you have no mobile data on either SIM card. The phone is looking for a signal constantly and not getting it, that alone will drain battery, not to mention using dual sims has been known to affect battery life as well. Is the phone in airplane mode in that picture?

You aren't alone. I've been fighting the same issue with the battery drain since March. Up until the June update my excessive battery drain was showing as "Mobile network" but now it shows as "Phone idle". Strangely it drains the most when not in use. I've already done a factory reset and ended up with the exact same issue instantly.

It may be worth trying to disable the "adaptive connectivity" setting and see if that helps. I live in a weak 5g area and my phone was constantly switching between LTE and 5g causing signal drops and battery drain for me. I turned it off and it helped with both issues.
Settings, network & internet, scroll down to the bottom.

Tried almost everything except this one. I noticed this option was enabled on my phone. Turned it off today. Let's see how it goes. Thanks for suggestion!

Not in airplane mode. I turned off Data then why would it constantly look for signal?

I guess I should have asked first, I wasn't sure if you turned data off or not, I guess that's what led to the airplane mode. What about in developer options? Is mobile data always active still set to true?

Anyone with this issue my best suggestion would be use some kind of doze optimization mod. I know nap time is kind of outdated but some things still work correctly. I believe all of it does except for the GMS does magisk module. If you scroll all the way down to the bottom there's a setting that says wait for unlock. That keeps the phone in deep doze mode until you unlock the device, which also keeps the sensors turned off as well. Another option is diamond John's app Temefi. In the search box, type in doze, and you'll see a place where you can choose from several different Doze profiles. For this you need root, but if you're not rooted I would stick with nap time which just needs some ADB commands entered

i think it's a bug, i have no drain but look at the screenshot
"telefono inattivo" is phone idle, same percent but 1hr and more compared to yours, strange, indeed i've no drain
i always keep data, wifi and bluetooth on, since i work in a place where there's no 100% coverage of wifi, and bluetooth for smartwatch connection

have you tried safe mode?
