[Q] Lost 30% of battery in 2 hrs.

Is this kind of performance normal with Android?

What ROM are you running?
How much were you using it?
How many Widgets are you running?
I know I'm running an OC i9000 kernel with a live wallpaper - so my battery life is pretty horrid.
And if your coming from a non-android phone? The battery life will be a lot worse then what you are used to. Between the AMOLED screen and if your running a custom ROM battery life will get worse.

What ROM are you running?
- Cognition.v2.3b8/Launcher Pro
How much were you using it?
- moderately
How many Widgets are you running?
- Beautiful Widgets (Weather/Time), Google Search, Google Voice, Launcher Pro Calendar
And if your coming from a non-android phone?
- Came from iPhone 3G
Other Apps: Lookout, tasker, advanced task manager

One suggestion: You don't need ATM. Android can manager the memory quite well.
And no, this performance is NOT normal. Did u try recalibrating the battery?

Yup.. loose the task killers/task managers - that will cause you more battery woes than anything. Especially if it's trying to kill a task/application that just sit there and restarts - causing a nice infinite loop of battery death
I came from a 3G as well. Had to re-think on how to use my phone. The greatest thing about Android and its hugest fault.. is you have to manage everything yourself pretty much.
I would suggest turning off basic processes while not in use (wireless, GPS, and even synching)
Also dimming the screen even just a little bit will help.
Beware that most of the ROM's out today (including Cognition unfort) are terrible with battery life. Most of it is related to i9000 ROMs being on Captivate devices and are horrid at power management.
BUT.... even if you were on a Stock ROM you will notice less than stellar battery life with your device vs. the 3G.

I am experiencing similar shock to X10D3. I am coming from an iPhone 3G with my work email being pushed. I am currently running Assonance 5.0 with my work email still being pushed. I wiped battery stats using clockworkmod, turned brightness to minimum, have removed the calendar and news & weather widgets, so that the only widget I have is picture frame (and it is not running on the main screen). Additionally, I changed my wallpaper to a near-black one and only have 4 icons on my homescreen. I also keep wifi, BT, and location services turned off.
I am currently at 88% after being unplugged for about 2 hours. All I've done on my phone is play Word Feud for 5 minutes, check my flight on FlightView, and read a few emails.
With my iPhone 3G, I could have easily gone an entire day without having to plug my phone in. However, with the Captivate, I find myself having to plug in after 12-15 hours, even with what I consider to be pretty moderate use.
One thing that was mentioned is that these custom ROMS tend to be battery hogs. Would I be better off (battery-wise) running the stock 2.1 that came with my Captivate? How about if I ran 2.1 but just rooted the phone to eliminate all of the AT&T bloatware that may be running in the background?

On a day of moderate usage with about 1-2 hours calls and about 1-2 hours screen being on, system up time at about 12 hours, I have my battery at about 50-60% by the time I am home in the evening. I talk on phone on my car bluetooth most of the time.
I have two gmail accounts set to push, and google voice set to push all the time.
Auto-sync is constantly on.
Brightness set to minimum since I am not in sun most of the time.
No task killers installed, nor have any CPU speed reducers or anything like that.
But one thing, since I don't stream data so heavy (EDGE is fine for my email/xda/chatting), I am on EDGE all the time.
The ROM I am using is in my signature.
EDIT:
My phone stats today till this minute
Time since off charger: 5 hours 30 min
Calls: 29 min 2 sec on bluetooth (I turn bluetooth off when I am not in my car)
Display on: 1 hour 25 min
Sync accounts: 2 gmail, 1 google voice
Weather widget set to refresh every 4 hours
Brightness: 0%
Network: EDGE
Battery at: 70%

[Q] Battery draining even in sleep mode

Guys, I have been using the Incredible S for the last 5 months now and my battery always used to last the whole day. In sleep mode, it never used to drain more than 10% through the whole night. I don't use GPS, Bluetooth very rarely, no Wi-Fi, brightness @ 30%, backlight @ 15 secs.
However, over the last 2/3 days my battery is draining like anything. Last night it drained from 45% to 3% through the night without any usage.
Can someone throw some light on this issue

Probably an app you downloaded keeping your phone from going into deep sleep

Yeah what applications do you have installed? Words with Friends was the biggest culprit for me.

Get the application cpu spy to check for deep sleep and use a monitor app to check for high cpu usage from apps

Thanks for replying guys!
Haven't really downloaded any apps recently, Downloaded ADW Launcher and then uninstalled it.
Can you guys help me with some monitoring apps and is Cpu spy an app?

is your mobile data turned on? if not, presuming u have downloaded anything since u bought your incs, chances are your battery is "leaking" charge. replace the battery

I have quite a few apps; facebook, ebay, whats app, Go SMS, sky sports and news, titanium backup, fonts installer and currently running VU v2.39.0. By midday I have lost around 40% battery from full charge over night. I'm loosing about 1% every 5 mins!
Have stopped using live wallpapers, unchecked auto sync and always-on mobile data, using battery booster to control wi-fi so it is not always on, do not use bluetooth, brightness less than 50% and screen timeout set at 1 minute but I always lock it anyway. I have also installed system tuner, but to be fair I do not really understand it all, especially governors and frequencies ect. I have also calibrated the battery recently and wiped the battery stats a number of times.
Do I have to uninstall these apps in order to get half decent battery, which for me kind of defeats some of the objects of having a smart phone! Sleep is when the screen is off yes?

With system tuner you can check how much cpu an app has been using. Very high amounts usually means a rogue app that isn't allowing your phone to sleep.

[Q] Maximizing battery life

Hello guys,
Can you, people who are getting around 6h of battery life, share your tips & tricks in order to do so ?
Sharing some of the settings you did or didn't enable would be great !
Thanks

I know that Google Now and Latitude drains a lot of battery. Turn that of if you want better battery.
Sent from my HTC One using xda premium

I would also suggest to turn of facebook notifications. U could decrease weather update interval from 1 hour to 2 hours and have your energy saver option always enabled. This cpu will get downclocked from 1,728 ghz to 1,134 ghz and u will notice no difference in games or anything..not even in very very demanding games, cause this cpu is extremely fast (even underclocked it is faster than one x+ cpu or galaxy s3 cpu)
Sent from my HTC One using xda app-developers app

I use power saver as I don't game, and I honestly can't notice any difference apart from improved battery life.
I also turn off mobile data when I'm out of the house and not using it. Constantly syncing data, especially when you have poor signal, kills the battery.
Sent from my HTC One using Tapatalk 2

Thanks for your input guys.
I also read somewhere that it's better to select 2G/3G network over 2G/3G/4G so I will be monitoring that.
Regarding the meteo app, I'll set it to refresh once every day, which is plenty enough. What I will not do again though is install Avast!, looks to me like the damn things tries to connect to the internet every time you unlock the screen (in order to check for updates I guess).
Google Now & Latitudes will be disabled, as I don't use them.
Keep the tips coming

Personally I find the battery to be great i leave everything on do lots of web browse YouTube games and i use it as a phone as well lol and will last me all day and some

You're very lucky. Out of the box (by that I mean I didn't change any settings) I only got 3h30 screen time (albeit most of it was 3G browsing, but still, that's pretty low compared to what others are gettings, 5 to 6h easily)

It might be because I'm on a custom rom don't know but i do leave my phone on charge for 5 hours when i get home plus I read somewhere if you run the battery down 3 times it will last a lot longer so i did

I took my phone off an overnight charge at 7 am this morning. It's now 12.35pm, 5.5 odd hours on battery and I still have 94%.
I've sent several texts, checked Facebook a few times through the course of the day.... I do have power saver on.
I don't have updates coming to my phone 24/7.
The way I like to use my phone is, I only get updates when I want them. I.e, when i turn my data connection or WiFi on.
I couldn't think of anything worse than being pestered all day from Soundcloud/ Facebook / Twitter / Google.... etc etc. Updates/notifications.

actually if you constantly turn on the screen the battery drops really fast.
I think if you're on a stable network, you should just choose the network model you use (2G or 3G only)
also, turn off auto sync and kill background programs that you no longer use should save some energy.
6 hrs is average. I unplugged the phone at around 8:00am and by noon only about 55% left. Though the screen basically never off coz I kept surfing the net and texting.

Snapdragon Battery Life only got me ~12 hours

I just bought the note yesterday from a local Verizon store.
I really love it but my battery life is literally TERRIBLE. I've googled a bunch to try and find a solution but I haven't gotten a straight answer. I've heard to resync your google accounts, swipe data and reload everything, but nothing have seemed to be solid.
I am a pretty avid user of my phone and I decently know what I am doing. I am coming from a Razr Maxx x912 with CM10 snapshot M11.
So I charged up to 100% at 10:38 am this morning, went to the Cardinal Lions game. Wanted test the phone out and used pretty significantly. When I got home it was 6:00 pm and I was left with 26% battery. That is not okay.
I am using Google Now Launcher because I hate that you can't center the apps icon on their launcher.
I have location on/off when appropriate, wifi on when needed, no bluetooth, automatic brightness, close out active programs, etc. Nothing out of the ordinary that would suck up the battery.
My battery stats are reading with Android System at 25% use and Screen at 22%.
I've read people getting a total of 22-24+ hours with their Note 4. I'm not even getting about half that.
Did I get a bunk battery? Does anyone know of something I could be doing that is abnormal for battery use?
The phone does runs hot to the touch on it's back. I also get messages from advanced task manage that cloud or facebook has lagged and overdraws battery. I don't know of anything else I've done differently than any use of my other phones that would change my battery draw.
I'm willing to go back to the store and swap out this phone for another Note 4 because I do love the phone.
If anyone would have any ideas I'd appreciate it. Thanks!

I consider myself a moderate to heavy user (gmail, hotmail, facebook, linkedin, dropbox, whatsapp, skype all syncing), often reading news and diff articles throughout the day, light game use.
I only leave wifi on when i'm at home or somewhere where i connect to wifi, otherwise it's turned off.
I usually get from 7am - 11pm with 30% left. Screen on time is the killer - playing games i notice the battery drop quickly.

I would say I am at the same level of use. Emails read and write, Reddit poops, typical facebook scrolling, instragram butts, news, text, Use bluetooth at the gym with wireless headphone, but no games or anything really consuming.
Do you see my situation as typical or atypical as in, is it obscure enough to go in and ask for a different Note 4 since because of the battery?

I assume that your phone would have been using more battery at a stadium with 50, 000 other cell phones its visinity. Your phone would be losing a lot of packets with so much traffic around it

that might be the case but as I was reading forum posts about the battery life on the way home from the stadium I could watch my battery % decrease. On a 20 minute car ride I went from around 33% to 30%.
Compared to other reactions to the battery life online, I don't doubt my battery is depleting abnormally for some reason whether it is in a stadium or not.

Yeah it seems to be draining a bit more than mine. I also listen to about 1-2 hrs music (or podcast listening), plus 1 hr using Runkeeper (that by itself only drains 3-4%).
Maybe give it a few days for the battery to settle in, then see what kind of battery life you're getting?

Are you using Lte, 3g or Edge?

On 4.4.4

Im moderate user with dropbox, google drive and 3 email accounts sync on. With power savig mode on I go from 7am to 11pm on 60 - 65% battery capacity. I keep screen on manual settings (automatic is to low for my likings) and phone is not rooted so I can't disable some applications running in background (same of them i.e tmobile my account I can close manualy in application manager). Install battery monitor to check if your phone ever go into "deep sleep" or if there is offensive app what keep it "awake" all the time.

Why do you say this? I've never heard to not use them before, so if something else is more efficient or less burdensome that would be great! My task killer has given me the message of apps causing CPU lag and overdraining the battery wit the option to "BOOST". Not exactly sure what this means.. I assume it means boost (kill) completely. Is this normal?
I'm complaining because I've heard so many people loving the battery life on their Note 4, claiming to have a battery life of 22+ hours while I am barely getting 13. I want to ensure that I didn't get a bunk battery and that I might need to swap it out at the store. I love the phone but it bothers me to watch the battery % deplete before my eyes as I use it.
That being said, I watched 20 minutes of the science of interstellar last night after draining the battery completely and then charging it back up to 100% and at the end of the 20 minutes 92%. 8% loss over 20 minutes of video should not happen. Have anyone experienced something similar?

Since Android 2.3, task killer apps will significantly reduce your battery life. When an app is sitting open in the background it is just stored in RAM and is not using any power. When a task killer tries to kill it, it removes it from memory and then the system loads it up again. That causes power drain.

Was that a streaming video or locally saved? If you're streaming over LTE I wouldn't consider that too unusual.
You also haven't given any screen on times, which are very important. I can let my phone sit idle and get ~15 days out of it if I don't touch it, but I could also use it for 7 hours of watching a movie with the screen on and kill it.

I was streaming it over wifi via the youtube app, so it was nonlocal.
My stats show Android system at 27%, and Screen 12%.
I charged to 100% this morning and am at 93% now after screen time of 13m 15s.

That's actually really bad if it was over WiFi.. I had this test done (and throughout that post), but the one linked is at 95% of 41 minutes OST (1st post on that page); I also have three emails running (Push - two hotmails, one exchange for work); My test was basically running a Crunchyroll video for the whole time.. I was able to get a little over 8 hours OST at the end of the test; However, if you left your phone on for a few hours, then that's pretty good.. remember the standby mode does kill battery too.. I use a 'deepsleep' mode when my screen is off (80%+ deepsleep from CPU Spy);

CPU Spy for 48 seconds.. I'll post one with a bit longer time next.. but you get the point.. try to get deepsleep when your screen turns off.. (for example, I turn off all the radios (except cellular and bluetooth) when I turn off the screen.. The app I use for this is DS Battery... I had the 8 hours OST test done while using DU Battery, DS Battery, and Memory Manager Full all at the same time.. so now only down to DS Battery left.. from what others say, the apps that clear memory are bad because it reloads them back into services/memory and thus gets more battery drain.. just like getting out of a car door (while you are driving to the store) every minute to check on something, then getting back in.. better to just sit and go the whole trip and get out at the end (which deepsleep mode can do).. the app can run, but it can't do anything because the wifi/mobile data radio is off.. (just like if there was no 'car' in the example);

5 minute run.. dropped a lot but still over 95% of off screen time is 300mhz or deepsleep..

Great. Thanks I downloaded CPU spy and DU Battery. I'll look into DS Battery.
Other than turning off radios when in DS, do you have any other suggestions?
I was using Google Now Launcher, which I think ran the Okay Google option all the time which sucked some life. I switched to Nova and relinked my google accounts and it seems to be running better.
Ill charge it full and then run it dry and report back with my results.

Turn off Google Now if you don't use it
Turn off Location/GPS or make sure it runs only in power saving mode
Turn off location history in Google settings
Use auto-brightness
Disable Pen detection in the S Pen settings
Disable S voice responding to double-tap of the home button (in S Voice settings)
Don't use the Google search widget which listens for the "OK Google" command
TeslaUnread for Nova Launcher prime drains some battery too, don't use this unless you really like it
Use power saving mode when going out for a big day rather than relying on it as the battery is almost drained
Disable any apps you don't care about i.e. carrier bloat, Google apps like Play Movies, Books, Newstand and Samsung apps like the TV/remote apps, video player if you're using an alternative, cloud syncing processes and print/spool ones as well. This may not make a big difference but it's nice to get them out of sight anyway.
And most importantly, as mentioned previously, don't kill your apps. The only time I kill an app is for big 3D games as I like them to go away rather than sitting in RAM. I also have a little routine, when I do a reboot and full charge, I run all of my common apps like Hangouts, Messages, Phone, Chrome and my weather app so that they are sitting in RAM already while my phone's at 100% rather than draining my battery during my commute to work in the morning. I don't really have any particular reason to do this as my batter never gets anywhere near 0% by the end of the day, I'm just OCD with seeing it drain too much before I even get to work.
I don't think most of the suggestions above are too extreme. Unlike uninstalling commons apps such as Facebook/FB Messenger, or disabling your data/wifi/bluetooth or even turning sync off. To me this is taking away from the purpose of a smartphone, but each to their own.

Hi
Got my p20 pro a few days ago, love the phone but have a few issues, mainly battery.
After seeing slot of comments saying how people are easily getting 6/7 even 8 or 9 hours sot I'm struggling to get to 5. I have display on auto, removed uneeded apps, have darkened colour selected for menus etc yet I can't get through a day of use (Twitter, email, internet and some YouTube videos) I do have Spotify on in the background slot, but looking at the usage settings the highest battery use for that has been around 241 ma, so not a great deal
Is there anything obvious I'm missing?
A second issue is that when using pinch to zoom in you tube in landscape mode I get a line between the screen and the notch which looks like a weird display gap and is really annoying, anyone else get that?
Lastly...in camera mode I've watched a ton of phone reviews and night mode is a swipe able option along the bottom, next to aperture mode etc...however I don't have this, I have to go into more then night mode, anyone know why that is? ( I'm in the UK if that makes any difference)
Thanks for any help you can give

Same here, Im not impressed with the battery.

Same here. Its not a deal breaker though over night
I lose 2% on idle with aeroplane mode on and then shortly using 2% drops off.
We seem to forget that this is the initial release of the firmware - I am sure huawei will optimise it further to improve battery

My phone nearly always gets charged overnight, the fact that this is now easily getting me through the day with zero scares is good for me, I'm not trying to eek 2 days out of it, if Huawei somehow get that then all well and good, but for now I'm happy knowing it's unlikely to die on me if I leave the house at 100%

I had the same issue, but seem to have stabilised it.
Try the following :
Stick to one resolution rather than smart.
Disabled adaptive eye.
Keep the notch on
Managed all apps manually (setting only my key apps to auto and run in background)
I also deleted the cache on all apps and the system via boot menu because I think migration caused some of the issues.

I'm sure mines got something going on in the back ground, fully charged to 100% left in standby while driving to work, arrive (30 mind later with the phone not used) and it's gone down 3%.
Tried the settings above and have manual control over all the apps, I kill off apps after I use them and it's still draining worse than any phone I've had for the last few years.

That is the same menu i have (i'm in Belgium)
i have to go in "more" and then select "night shot"

Yeah, the phone menus are a step backwards from the mate 10 pro. Dunno why they've done it this way

Same here!!!

I get between 8 and 9 SOT a day, Wifi most of the day, 3 hours netflix on 4g with BT headphones, instagram, whatsapp, web browsing, streaming deezer music on BT headphones, texts, some calls. No snapchat or games though and facebook is not logged in.
Haven't tested standby drain yet but maybe it's standby that's killing your battery?
This is in one day though and is excessive use as I have two Instagram accounts and lots of work emails as well. I also don't have a pc at home so use phone for browsing.

How is your settings within the battery category? Do you manage the apps to etc run manually or what do you have in the settings that gets you so much of SOT?

So after some days of testing and trying out some battery monitor apps, the max SOT that I get is 5 hours and 45 minutes.
GSam reports that Android System and Kernel (Android OS) use more than 30% of the battery combined. Is that normal? I'll attach some screenshots.
What I also find interesting is that the AccuBattery app shows that the estimated capacity of my battery being at 3500mAh out off the 4,000mAh design capacity and battery health is at 88%.

I'm sorry but how do you achieve this? I barely get 5 hours SOT with WI-FI on, instagram, messenger, facebook etc. Also my apps are running on AUTO APp launch.

Have you figured out what is causing the problems? I'm having pretty similar issues.

Unfortunately I haven't had any luck either. I've deactivated almost everything that could be using up the battery and I still don't get more than 6-7 hours of SOT... I've had the phone for two months now, battery life didn't really get better as some people mention. I carry a powerbank with me cause when I'm out and taking photos it doesn't even make it through half the day...

Did you guys deactivate the option mobile data while connected with wifi? That drains a lot of battery while connected with wifi and is activated out of the box for no reason. What also drains battery are the two options under location settings to search for wifi networks all the time.
When I was on emui I set all apps to manual and only activated active in background and auto start for apps that really need it and I want to get notifications from, like WhatsApp and telegram.
Under mobile data settings I also deactivated background data for those apps and boom, easily 10+ hrs SOT when on WiFi or 7-8 hrs on mobile data.
I'm running force Doze app as well but that might only help with standby drain.
Oh and get rid of Facebook, messenger and snapchat if you want good battery. They are known for huge drain and there are good or even better alternatives like Friendly e.g.

That does not sound too bad...At least you're getting 6-7 hours of SOT. I'm getting like 4H MAX lately. And that is mostly internal usage! with low brightness.

Thanks for that! I've just disabled "Mobile data always on" and we'll see how much difference does it make. I also might give Friendly a shot.
Also, if I disable background data/app launch for Facebook, that will surely prevent facebook to sync constantly, right? I don't need constant notifications from facebook, only from messenger.
Also I noticed I went to sleep with 100%, after 7 hours I woke up with 92% left. That is with Always ON display. Is this normal standby drain? I'm also thinking about disabling always on display as it does not show notifications correctly anyway.

Yes that should prevent notifications from Facebook.
Hm when I charge it to 100% I usually still have 100% when I wake up 7hrs later. That doesn't mean I have no drain but I think the phone stays at 100% fairly long and seems to drain faster on low battery percentage (similar to iPhone afaik). When I charge to 90% for example I wake up with 87% or so. That's more realistic I think. Wifi on, everything else off, no AOD.

What system apps do you deactivate background data? I just did it to some of my installed apps and i hope i will see a diffrence soon. And where can i find "deactivate mobile data when on wifi?.
Thanks

Not too many actually. Could probably deactivate some more but seems fine as it is.
My system is German but it must be somewhere in wireless and network - mobile network - advanced.
