wow you seriously get that backup???
do you have mobile data on all time or just when you need???

Me too. Never thought i would get battery backup like this. I got only a day and a half of battery backup max on my old Galaxy Nexus.
Mobile data always ON now, but also have STAMINA mode activated which cuts off mobile data while screen is off. Also Wifi is automatically deactivated when i leave home and turns on when am back!

Here's my battery backup. Heavy day and I was on the road from morning to evening.

Standby Loss?
My experience with the battery has been mixed.
The standby time is great. But sometimes i experience abrupt drop in battery level (about 4%) while idling and no background apps, data,bluetooth, wifi all off.
Also, can someone please tell the standard battery loss for following scenarios (in % loss per hour or other time intervals)
1. While using Mobile Data (not WiFi) and browsing on Chrome ( I lose 17-20% battery per hour)
2. Sleeping with STAMINA MODE on. (i lose 3-4% in 6-8 hours overnight)
Any replies or help is appreciated.

What kind of sorcery is this??!! :silly:
GREAT!! :good:

Thought I should update once more.. This time I have more voice calls than screen on time.

Using Opera instead of Chrome, I have seen far less battery usage and also memory usage.

It's better battery life than GNexus for sure. but playing game really drain up the juice

Usually using Calls, SMS, Internet (Jasmine, Twitter, YouTube, Opera) via 3G and Wi-Fi, listening music via BT PowerAmp -
Gaming RealRacing 3 from 96% to 28% -
Good Battery i think.

l love my new phone. l`m just loveit. He have a verry good baterry life comparated whith my old HTC Sensation, doble l can say or more.

Ciao
I just bought the xperia ZR. I haad sgs2 and I was very please with that phone. Recived OTA 4.2.2 as I turned on the phone. Updated.
Screen, design and UI responsivness is just top of the notch.
Camera in low light envirioments is poor, pics are full of noise... You have to play a lot with the settings to get a decent pics. I heard that is a software problem... Well... I hope they fix it soon cause is worst than sgs2 pics which has less MPixl.
Question about stamina mode. I turned on but I do not see it working... Please spare me lessons on how it supposed to work. I do know that. When I turn on the display the H o 3G icon is there as the networks never been shutted. I still receving FB whatssapp notification, and i didn't put any app in the allowed list.
I read that many other guys experienced this sort of problem after updating to 4.2.2
Any suggestions? Is yours working well? So u have always the network logo?
By the way yesterday was first day without stamina the battery hit 13 hrs with 1hrs call and 3hrs screen on. Not bad I might say. But I cant get 1 or 2 days as guys with stamina did....

has anyone tried the mugen power batteries yet? I watched the video showcasing the 4600mah battery and it kinda looks like they doubled the thickness with the new case? I don't think i would want my phone to be that thick so can anyone who has it post comparison pictures, or at least testimonials about the 4600mah and 2500mah ones.

Glitches in Battery Status
After 10.3.1.A.2.67 Update (jellybean 4.2.2), there's been glitch in battery status, sudden drops in battery level. Anybody else experiencing the same?
And Take Screenshot option removed from power option menu? I don't see it after update.

so far didnt experience any battery problem. but screenshot option is no more there. liking this update

Problem in 4.1 too!

I haven't updated to 4.2.2 yet, but I have sudden battery drops (4-8%) with 4.1 JB on C5502. It usually happens when battery is below 40%.
These drops have happened more than 20 times in last 2 months.
I was hoping that this issue will be fixed in 4.2 update?
---------- Post added at 11:07 AM ---------- Previous post was at 11:02 AM ----------
You have updated to 4.2.2
Could you please tell me the size of the update by PC companion? Is it like the FTF( 700MB) or OTA update (200MB).
I have limited data for my connection.

Does the screenshot shortcut i.e. pressing power button and volume down together, work on the 4.2.2 update?

I am loving this update:victory::laugh:

[Q] Battery drain

I have had this tablet and keyboard for about a month and I can not seem to get more than about 6hrs of battery life/screen on time. I usually have it in smart saving mode and use it to take notes, surf the web, and some video watching. Yet, this tablet and keyboard can't seem to match my old TF700 battery stanima, usually about 12hrs with the same type of usage. Thus, should I exchange this tablet and/or keyboard for another one or is this normal? Any advise would help
P.S. Same battery life after a factory reset and no apps were installed to make sure it wasn't one of my apps that was cousing this issue.

Hi
Same battery life with my first TF701.
Same with the second one (after I brought the first one back to the store)
---------- Post added at 09:14 AM ---------- Previous post was at 09:10 AM ----------
However it seems to be a little bit better with the wifi disabled.
My tab has been produced on november 2013

Interesting! My TF701T gets much better battery life than my TF700T.
You can download better battery stats or wake lock detector to see what is causing the drain.

Moreover i was thinking about the charging cycles.
I have this tablet since a bit more than 2 weeks now and I charged it just 4 or 5 times. Don't you think it could be the "charging cycles" which are not already completely made ?

Hi guys, sorry to jump the thread but I'm having severe battery drain issues recently. I charged the tablet to 100% and went to work (no WiFi signal). 10 hours later I get home and the battery is at 28%! Not switched on screen in between or used at all.
any ideas?
Owen.

I´m on the same boat, I've been doing some testing and I have concluded that the latest update of Google Play Services does not allow the our SOC going into deep sleep. The version of google play services in question is 5.6.87 ( 1599771-030 )
The problem is that all new Google apps ( mail , calendar , etc. ) with material desing are associated with this versión.
The only Workaround that has worked for me is: Installing Cromix rom from scratch and update all apps except Google apps.
It seem that we have to wait an update from Google to eliminate this bug
Here are some of my tests with no Gapps updated (yes!!! 6 hours with 100% of charge )

Exact same symptoms as you guys. Never had such severe battery drain on my tablet before, but in a matter of 6 hours I dropped 23 percent, just sleeping!
Battery use shows the same thing - crazy battery drain due to "Android OS". I did disable those aforementioned services, but just also froze Asus Browser to see if that is the culprit. Regardless, this is a big problem! I'll report back if I find a fix too.

Thanks for sharing your results! I'm wondering, however... if what solved the problem was simply a factory reset / fresh install. It's possible that it's a problem with the new Google apps, but I suppose the only way to know conclusively is to update your Google apps and see if it immediately goes back to draining the battery. Have you done that?

Yes, i did and after the Gapps was updated the drain start again. First time i think that some Asus app was messing all, but after one fresh install i forgot update Gapps and the drain stopped suddenly and thats trow some light to drain mistery.

I try that, but draining only stop if wifi was off. :cyclops:

During this night: from 100% to 25% in 8 hours, after a full wipe and cm11 flashed; so I decided to do my tests.
Now I'm testing the tablet this way: I updated all gapps and also google play services. Then, through titanium backup I locked google play services (obviously, gapps won't work...). Now it's charging and I'll let you know my battery drain...
We have to comment and review this app on the Play Store and ask Google for a new update!

I've not bothered to root my tablet as it's been perfect so far in its stock mode, except from this latest issue with Google Services. How often do Google update Google Services? I know I've seen the update every so often but I doubt they do it regularly?
Not fussed about a custom rom as I#m happy with stock (and don't want to lose all my data etc.) but it it's the only way then....
Owen.

In the same boat here with my TF701, the GApps seems the root cause.
Rollbacking only the google playservices to 6.1.88 did not solve the issue.

Well, here are my results so far.
Setup 1:
CROMi-X, Play services 5.6.87, Gapps updated to latest version, disabled GCMSchedulerWakeUpService as susggested in another thread
Still drained 31% in 4.5 hours of sleep, so that's almost 7%/hour
Setup2:
As in setup 1 but also disabled all wearable services with DisableService app.
Drained 34% in 4.5 hours of sleep = 7.5%/hour (this was with WiFi off, btw!!)
Setup 3:
Clean installed CROMi-X 7.0.3, did not update Gapps, did not restore any of my apps, Play services is v5.0.89
Drained 6% in 10 hours = 0.6%/hour (WiFi was on).
Next I am going to restore my apps, leave Gapps as they are and report back.
In another thread someone used the Autostarts app (the paid one) to disable all Google Play services from auto-starting and did not have the drain on Play services 5.6.87. I am going to leave that test for later. Don't know what that does to Gapps functionality or if the drain returns after using Gapps. But if someone else wants to test it....

I installed DisableService from the Play Store and disabled "Wearable Service" under Google Play Services. From 74% to 68% in 3 hours in sleep mode...

Here's an interesting article on battery drain caused by GP services and a solution:
http://www.reddit.com/r/Android/comments/1zxri4/google_play_services_battery_drain_the_real/
Anyone on GP services 5.6.87 care to try taking those permissions away and check if it does anything?
I am going that route later - want to stay on my tests for now....

I's about an hour now since Google play Services 6.5.99 updated with screen off the battery dropped 1%. I think it solved the problem for me.

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

P30 pro bad battery life

Hi guys! I have p30 pro with 153 software. I see that many people are getting SOT around 10 hours. I'm light user, i have disabled everything that i don't need to save battery, togled dark mode, apps to manual launch too, I have good reception but I am getting about 6 hours,
6.5 hours of SOT and as I see everybody is getting better SOT with similar usage like me. Look at the screenshots.

Cleared your cache in recovery after updating ? Im on .156 and battery has been amazing. Even on .153 it was really good.

Any rogue apps? Apps which keeps the phone awake?
Usually with 6.5 hrs of sot, you should have at least 20% left.

puzzled because other people getting great battery life.
After a little while (1 week) , I did a factory reset and did not import any setting through Hi Suite. I start fresh. I did not update any apps at all, just the system update. Then my battery life is great as it suppose to be.
It last for 5 days with great battery life. Then, suddenly the problem reappear again. Not sure what caused it. For me, I realised the "Phone Services" usage was at 34% ( normal usage is adound 0.8%) - >look at setting>battery>usage. I really hope somebody can provide ideas on how to solve this permanently.
Atleast I have confirmed it is not hardware problem. Most probably is software related issue.
Wjat kind of app caused this kind of battery drain.

I can't upload screenshots, otherwise I would show you my usage. I get 6hrs sot ant 10percent left. I am not playing any games or so, just using facebook and messenger as normal. I think 6 hrs with my light usage us bad. I have cleared cache, done factory reset, enabled dark mode, reduced brightness etc.. Problem still exist

I may have a solution to drastically improve battery life but it's a bit tedious and time consuming.
Go to Settings - Apps-Apps again and open each app installed on your phone and for each app go to Data usage and uncheck Background data.
Warningo this only for the apps you know you won't need them to be running in the background!
Thank me later. Good luck!

It won't help, I already did that for apps which i don't want or don't need. I think i'm gonna take phone to warranty service then. I tried everything I think...

I had the same problem.. Had battery drain 10% per hour with/without using the phone..
I have cleared the cache and turned almost all apps in apps launch in manual mode.. Since then I have around 7-9h on screen time, it varies but I am not sure why.. However, a few days ago I chose only 3g in network mode in settings and got 11h on screen time after that (youtube 4,5h, fb 2,5h, instagram 2,5h and some other apps)-basically all SOT was on apps, so those 11h makes an amazing result... It is yet to be tested whether that 3g settings made the difference, maybe it is just a coincidence..

Have you done this for ALL apps that you don't use?
I did this for every app and disabled background data for all apps with the exception of a couple of them I use daily (Whatsapp, Gmail, Phone, Sms) and it made a tremendous difference in battery life.

If you have better signal with 3g it would explain the better battery, poor signal is the worst for battery.

I guess that is the catch, my 4g coverage is not so good.. I am getting 12-13h on screen time regular now, using apps like youtube for around 4-5h, facebook 3h and instagram for 2h.. The rest are phone calls, camera and other apps... The battery life is amazing..

I think I figured out why my p30 pro had a poor battery life before. The battery are draining abnormally even without using it.
Previously, I was using dual sim card.
1st sim was a 4G sim that can (call sms and internet)
2nd sim was also 4G sim but solely for internet purposes (cant call or sms- it has been set that way by the telco).
What i noticed was whenever this 2nd sim card was inserted, the "Phone Services" usage will spike and it was used by Sim Toolkit apps requesting Location all the time which sucked out the juice.
I didn't suspect the 2nd sim card at first because I did use it on my Huawei Mate 20 and the battery was superb.
I did not know why the second simcard behave this way when inserted in my p30 pro...
So now, as a solution, I only use my main simcard. Battery was again great. Got around 7hrs SOT with 25% battery left.
This is good enough for me. Also today I was recording 4K videos. Perhaps that affect my SOT.

Hello, do you know what is the Huawei data management services,it drains 7% of my battery
Thanks

I wouldn't swap my phone for anything else even after the ban.
5:30 hours sot with 50% left.

If you have Facebook ,Instagram, or Snapchat that could be why.. Lightroom is using a lot as well

Terrible SoT..
Hi guys,
I have serious battery problem with my p30 pro. While others are getting 8-9 hours of SoT. I am getting max 4.30 hours. I don't play games there is not a one in my phone. Usually using just for whatsapp and surfing. I don't have Facebook either.
Always on mobile data and, 2-3 hours hotspot on in a day.
Could you please tell me your opinion what is wrong with this device. I added some screensshots from batterystata app

You know Hotspot really drains the battery right? Can you not use that for a day to compare battery stats?

This is the current SoT from my Huawei P30 Pro (VOG-L29) with the brand new EMUI 10.0.0 (Android 10, stable).
Amazing work from Huawei ???? ??

This is the current SoT of my 2nd day of continuous usage without charging the battery (down from 100%).
I have always the GPS signal turned ON, as well always a net connection (Wi-Fi or mobile data, but not both at the same time). I've also kept every single app open (w/ minimize swipe-up ?? gesture).
I also have my Huawei Watch GT-614 continously connected by Bluetooth to my Huawei P30 Pro, using Huawei's own Health app always running in the background, continuously measuring my heartbeat and counting my footsteps as well.
PS: this time, half battery gave me more SoT because I didn't turned ON the Performance Mode at any time

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.

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.

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.
