Battery Life is Terrible - Samsung Galaxy S7 Edge Questions and Answers

Alright, well, I listen to music a lot so maybe this is why, but I get like 1 hour SOT tops while listening to music for 1-2 hours ish in the background. Stock Android N and Ambasaddi ROM both suck for battery. I literally removed Facebook too and it still is very low. I use Google Play Music if it helps, maybe its just really badly optimised.
I don't recall my battery performance with Android 6 so I don't know if its just a problem with Android N :/
What can I do for good battery life? Are there any reliable daily driver ROMs, even with AOSP, that can get good SOT like 5-8 hours?
I tried disabling Nearby devices already, Bluetooth/Wifi Scanning etc, nothing helps. My phone is unreliable because it hardly lasts a day

install bbs and see whats happening- without info we can only guess (I don't have a crystal ball)

Help me out in HTC DHD

i am planning to buy HTC DHD in a day or two......
all my friends say the battery is poor and blah... blah..
but i like the design, features, etc...
is the Battery really very poor and is there any other trouble in that mobile!!
There are roms that could help you out. They can increase your DHD's battery life If you are willing to root your phone...
I most admit... With normal ROM, the battery really suck.
I haven't tried to root and put a custom ROM on yet, but only heard good things about it!
hey dude the battery usage depends on how u use ur phone
btw, i m also buying DHD on 17th very excited for my first Android
The battery is no worse than any other HTC, infact the battery is slightly better on my DHD than my classic desire.

I've got a standard DHD, not rooted and no custom roms and I have no problem with the battery. I can get more than 24 hours out of a single charge and that is with what I would consider heavy use.
Echoing what has already been said, yes the battery life can be quite poor. My phone will last for a "day" out of the house, by which i mean ~8am-6pm, but will be at ~20% when i get home, so will need charging.
That said, the rest of the features more than make up for that in my opinion
If you manage your data and what you actually use your phone for then you can get lots of time out of your dhd, if you slam your phone by downloading loads and streaming all kinds of videos to it and using gps on maps constantly then yea it'll go, but for the size of the battery and what the phone can do i'm amazed it lasts as long as it does.
Right now I'm at 11h and 39m with 56% left. This is with 3g on. Facebook and twitter every 30 min but its set to automatically update. Surfing, Texting, and a few calls were made as well.
Replace the stock ROM with one of the ROMs available here. I personally use LeeDroid 2.3.4 Beta 4 with an updated Radio. And I am very happy with it. It has given me a better battery life as well as removal of those useless HTC apps is a bonus. I still use sense which adds a lot of frills to stock android. Also look into the battery threads where there are ideas on what to do to optimize battery usage.
If you are getting your first smartphone you'll probably be disappointed in terms of battery. They are like little laptops and you know how much their batteries drain out. It's not that bad, but it's completly different than a normal phone.
You can drain the battery in 4 hours with very heavy usage, with semi-heavy it'll last for ~8 hours. With my use I get about 24 hours. I get up in the morning (15mins Wifi), go to school 15mins Angry Birds, 20 mins or more wifi, come home and wifi + play for 20 mins. Calls 5mins. Go to sleep phone on standby. Next day the same and after school I'll charge and it'll be at 5%. This is very light use.
I'm using Android Revolution, but I'm getting worse battery than with stock because I flashed a bad radio for Finland.
Other faults, I've only found one.
First: The speaker, it's pretty bad. Sometimes if you are in a noisy place you might even miss a call because of the silent speaker. Want to listen to music or watch youtube videos using the phone's speaker? That'll be hard...
I had the same problem with the ROM Cyanogen CM7.
Consumption of the battery far too high.
You should know that the HTC rom with sense use a proprietary driver and less greedy.
For other's rom's hacking in the kernel.
I returned on a rom with sense, Leedroid 2.3.4, I' have never eaten my battery so little.
For Rom's nosense, I wait that problems are solved

I'll second that. Mine is the same too.
Given the Pros of the device I will not mind the battery life. Its ok-ish.
I am on stock ROM and I kinda have better battery then when I was on Revolution HD. It gets better after a week usage and after a simple calibration. I get between 24 and 36 hours of medium usage and 3g and autosync aways on. I think its pretty great for this beast!

Battery life after update to 2.3.3

Hi everyone,
I've read in the update threads that battery life has improved for most since the update.
However, I feel that my battery is draining much quicker now. I re-did all the changes I made after the update (like removing Timescape widget + disconnecting from FB, switching off auto-sync etc). Didn't make much difference, though.
So, has anyone else experienced this? Also, has someone really checked if the camera bug is gone?
Regards,
cherryfish
Yes, the camera bug is gone. Personally tested that.
As for overall battery life, there's not much difference for me. Maybe just slight improvement in idling current. (idling battery drain is still about 1% or less per hour though... almost same as before update)
But I already have really good battery life before update... so maybe that's why I don't see much difference.
Non-rooted. Unbranded. No task killers.
that's weird, my arc's battery life is way better now, lt lasts 1 day 2 hours minimum.
my gf's been complaining about the battery becoming pretty hopeless....I have repaired, factory reset and uninstalled most apps and no respite...used to give 1 n a half days easily on mod-light usuage...now barely lasts a day...
need to figure it out..ill look more into it when I have time..
I have the same problem, looked good the first day now its ****, i can loose the last 20% in an hour while its just idling, today i was down to 9% after 12 hours, but i did use the speaker to listen to music for like 5 hours. Is there Anyone else that use the speaker alot that can tell me if it uses alot of juice?
Hi, I have got similar situation with u.
I have used titanium to backup and restore the system data and apps.
Is it the problem between old ver 2.3.2 system data and new ver 2.3.3 that caused the battery drain problem?
Battery life has doubled for me. I noticed that a lot of Sonys apps are no longer running in the background after flashiing the o2 2.3.3 over my Rogers rom.
Yep, battery life is way better over here too. I did a reset on it and set the phone up again pretty manually. Did sync my contacts etc. Works very well now.
Have 4 email accounts syncing, facebook and twitter syncing every hour and every 30 mins, do quite a bit web browsing on both 3g and wlan and have had w lan constantly on for quite a few hours now. Screen brightness set on 75%.
And now, after 15 hours and 33 min I have 66% battery left.
Battery life is really great & i am loving it. Those who have problems, i doubt there must be an app (if not more) causing problem. My brother got the battery problem on his Arc (battery drain 100 to 10% in 10 hours with moderate usage).. He uninstalled Handcent & started using Go SMS Pro & battery life is again good
For me, I was on work today... Wifi always on, Facbook auto update every hour, weather every hour, 1 hour 30 minutes music listening with bluetooth headset, 50-60 sms, 5 min phone call, half hour browser, played a game in 15 min.. and after 15 hours battery is till 60%... I am very happy
Waiting for the upgrade since camera makes battery die very soon.
Without camera usage battery performance is really good.
i did not transfer any userdata when i updated so taht cant be the problem, and i have the same apps as on 2.3.2 but i do suspect widgetlocker is eating up battery. I have also read that the wather app snowstorm that i have installed is a big batterydrainer but none of those shows up in my battery usage.
I see that the music player dubletwist is the biggest sinner except the screen but im assuming thats because i used the arc speaker for music at work.
But as you can see from the pictures i have drained the battery twice today, though the second charge was only up to something like 80%. And ive hardly used it after that(3-4 minute long calls and maybe 20 minutes of music using in-ear headphones and 30 min browsing). Something is wrong somewhere

My battery life has definitely improved it now must be about the best I have had on any Android device I have owned.
My battery life has gone from an average of 15 hours to an average of 31 hours with more usage. Im very pleased with the update best smart phone battery life ive ever had now:-D

I really don't know, but after a couple of reboots it seems better now... might be the reason.
Edit: I just installed Battery Monitor Widget and it says I it drains ~200-350mA atm. Wifi and 3G all off.
For me I defintely think the battery life is worse. I only ever use my phone on non-3g, all other connections off and got a nice 2 days easy out of it.
Since the update I would say I get just over a day (not sure if that is still good in other people's eyes) One of the killers seems to be the gallery which I presume is because of the new facebook update which pulls in your facebook pictures onto the phone....
Anyone find as well when you play games the phone gets really really hot i.e shadow guardians HD makes my phone just burn.
Easily upgraded today.
So far with using camera alot batt live is fine
and droping very slow on idle. Great!
Upgraded mine on Saturday and it's defo better on the battery. Wasn't using it at work and it was hardly using any power. Then started messing about with wifi and gps, etc, and it's still got plenty.
Haven't noticed many other differences though!!
Dazza
I have to charge my phone 2 days and battery is now at 54%.
I never had such battery life before even with bloatware apps removed with that usage.
Imagine if i remove them now! (Though i wont since i cant root with gingerbreak anymore, hopefully someone will implement it on the next gingerbreak's update)
Agree with everyone else here.
Battery life has improved with upgrade.
Battery life much better for me 50%

[Q] Lollipop battery life stats

Hi all,
Just wondering what the battery life is like for all you Lollipop users. I feel like the battery is around the same compared to when I was still using Kitkat.
I currently have 8 hours of screen on time with about 16% of battery left. I'm using AryaMod build March 16th 2015. No custom kernels.
Power mode setting is enabled, I don't listen to music, no GPS, no web browsing, but occasionally I do watch a few Youtube videos. I also use a lot of Memedroid and some textings with Line.
No Xposed installed (don't want to mess with it until it's stable for Lollipop) but I do use Greenify.
Anyway, most people might think 8 hours of SOT is a lot with 16% battery left. But if I look at BBS, the stats are rather disappointing. There are a lot of Google Play Services wakelocks (even though Google Play Services is already Greenified). I also see a lot of PowerManageService.Wakelocks under Kernel Wakelock. I've done the best I could to troubleshoot this but it seems like there's not much else I can do to optimize it.
Just wondering what battery life you guys are getting?
no one?
I justupgraded yrster to 5.0 on my note 3 and it is draining a lot fater. If there was a root i would get rid of the stock aps that run in the backround. I would say it could use a partial charge around 4pm if i take it off the charger at 630am

BATTERY LIFE: Heavy Use Endurance

Playing Candy Crush for 22 hours straight can take its toll on your battery (and your marriage). Rate this thread to express how the Note5's battery performs under heavy use. A higher rating indicates that it lasts a long time even when playing games, streaming video and audio, and doing other CPU-intensive activities.
Then, drop a comment if you have anything to add!
When using the Note5 heavily, I can get through an entire day...but barely. Like if phone comes off the charger at 7am and I beat the crap out of it with tons of use, it'll be at around 10% by 8 or 9pm. If I'm going out, I just put it on the fast charger and bam, I'm back up to 50% in like 30 minutes.
I'm getting 8hrs sot, with WiFi running continuous, but mobile data off,I'm moderate user,still my previous phone didn't last me a day,but thanks to this phone now I'm carefree about battery,well at least for me the quest for better battery ends

I just got the phone and am only getting from 7am to 1-2pm, then having to charge you guys must not browse the web a lot and use social media to much.

Dear All,

for me show 24hr8m.
would you help tell me about your phone it is the same or not.
Thanks

man this phone battery sucks, i use sometimes facebook, and have some news apps , some youtube, email, and bit of this and that
i charge it overnight and leave home at 8 am
and at 7 pm the phone battery is dead that is such a bad battery i wish to know how the people here praise its battery it really is bad
HI Man, it is as same as me
man today it ran out of battery so fast by 5pm it is dead, and i barely used it . Oh man i feel i did a huge mistake buying this phone
i tried factory restting it and still the same
this is so so so bad that i am so missing my iphone which was working great and had an amazing battery life
and add salt to the injury i ended up buying the sm-n920k which is the korean version and this has no rom support what so ever here on xda
i am so disappointed
For those of you that are having a lot of trouble getting through a day, I'd highly recommend this http://forum.xda-developers.com/note5/general/guide-bloating-touchwizzing-note-5-t3184563 because I got at a minimum 150% of my original screen on time compared to when I just got the phone.
Guys i don y know what you re doing but my battery life is amazing. By far the best phone and battery money can buy at the moment. Check it out http://forum.xda-developers.com/showthread.php?p=63851201
I'm not sure what you people with terrible battery life are doing. I hardly used my phone today but it's still been on for a while. Switch to T-mobile and put some cool stuff on it. I am by no means an android expert, but the quest for battery life is how I discovered XDA.
My experience is different. With moderate use i drain about 12% an hour. Then again im on the moar rom with no bloatware running in back ground. But heck even with heavy use. I have yet to see the phone less than 50%.
i am not using my phone when i at work and now 16:15pm. unplugged at 07:00am. total 12,5 hours on. SOT is 1 hours and now phone at %37. Heavy AndroidSystem and AndroidOS battery drain. i tried to use my phone without root for one week but impossible. %5 per hour. Battery graphic is going down everytime!!! This is so stupid!! again i will root my phone and i will use custom kernel and again everything will be fine again.
1) samsung dont know how to code a good kernel
2) without root note 5 is worst multitasking phone with huge 4gb of ram
3) without root i cant even delete that never use and never wanted phones by me (facebook or instagram or other bull****s)
4) without root i cannot use my phone without lagfree( because i must disable or delete some useless apps that allways sits on my RAM!!)
5) i paying lots of money and for use a good phone i must forget my guarantie!!
Thanks a lot samsung! note 5 will be my last samsung phone
Actually we must talk about that! Thanks !!

Thnks....
I get very decent battery life, check this thread.
http://forum.xda-developers.com/note5/general/battery-life-discussion-t3178480
I currently have all of the bloatware running, as well. I used to use Package Disabler Pro, but no longer find that I need to use it for battery life. 99% of the time I am NOT using wifi either.
Things I have done (to the best of my memory):
1. Disabled VOLTE
2. Wifi calling
3. Turn off location history
4. Remove Android Device Manager as a Device Administrator
5. Screen brightness set pretty low, but I have it set to auto as well
Probably a couple of other things I missed, but I believe those optimizations have greatly improved battery life on my phone.
Hope this helps.

Any one has this problem after the latest update i have battery drian faster and my phone always has used more than 85% from ram.(Note5 SM_N920c)???
i would say this accounts for heavy use...a little bit of everything but.mostly youtube 1440p videos with almost full brightness...some facebook, browsing,games, etc...only wifi. from this point till i reach 5% i ll use only data to.simulate further heavy usage - so i ll update the info as soon as i reach 5% or so...
my config : darthstalker v5, skyhigh kernel 2.6 undervolted by around -100mv on almost everything, if you want i ll post links to the synapse settings from othe threads...and frequencies locked to a57 min @600 max @2400mhz, a53 min @300 max @1500mhz, gpu 266/600mhz. coming up - only data connection from 51% to 5%.
and here s the end result (so basically 49% spent only on wifi and another 46% spent only on data...

Terrible Battery Life?

I've been getting godawful battery life - the phone comes off the charger at 8-9 in the morning and I am at ~10% at 3-4 in the afternoon with maybe an hour or two of screen on time. I'm running the latest build of PureNexus and EX Kernel, both of which are supposed to have better battery life. Android System is using 2-3 times more battery than everything else, depending on how long I've had my screen on. Should I switch back to stock (I really don't want to), or are one of these things in particular causing most of the problems?
What about apps??
Install WLD/BBS/GSAM to check the wakelocks..
If that doesn't help (which I think will help hehe) try performing a clean install of the rom+kernel
I have the same setup and I also get not that great of battery life. I get about 2H SOT for 12 hours of uptime. Theres no wakelocks or anything that shouldnt be happening. I just dont get good battery life. I don't even do much on my phone, I just reply to texts, listen to music, and occasionally google stuff.

It helps with many thing but primarily google now. It enables approx location for searches by scaning for wifi and/or bluetooth signal which is used to determine locarion. and also helps with smart lock I believe. Although that shouldn't drain that much battery.

The reality is... By only doing small and short tasks at a time, it uses more battery. Stopping and starting lots is a lot less efficient than constant running. I am able to get about 4 hours SOT if I do small tasks, nothing prolonged, but if I stream films or longer stuff, I get 5.5-6 hours SOT. It may be worth you looking at one of the scripts for the EX kernel governors, as one of them optimises battery life for users that don't have heavy usage. Do a quick forum search for it, it is worth a try!
The most important thing is to not focus on whatever figure you get for your SOT, as long as the battery lasts long enough between chargers that it is 1) better than your previous device and 2) good enough that it does not run flat between charges, then there is no real issue. People tend to focus on SOT as a defining factor of battery life, when it isn't the only thing to focus on!!
Hope this helps somehow.
Check to see what is syncing for your Google account. I had a ton of crap syncing that I don't even use. I restricted it just to mail, contacts and apps. Also, lock WiFi on to 2.4ghz instead of automatic. Turn off automatically scan for new networks.
Yeah I realize the thing about SOT. I was just giving it a number. Honestly the battery life just doesn't impress me. I wish it lasted until I went to bed, not just when I got home.

It is possible. I started off with diabolical battery life, but now I get through the day with ease. My only issue now is standby time, it is lacking a bit...
