Switching to ART 16% battery drop - Galaxy Note 4 Q&A, Help & Troubleshooting

This is probably a rough test but how much battery did you lose when you switched to art if you did? I was on 32% battery when art had finished switching over I was on 16% that's some drop, I know the CPU and ram must have a lot to do but come on.
The battery life I've had from this has been dire, I've been over the apps, I've lessened and lessened everything, I literally can't cut back any more, so the prospect of seeing 3 days etc just isn't going to happen, hence why I switch to ART runtime instead, I wanted to see if there was any gains, and yet in the time it's taken me to write this post, I've lost 2%.
Please can anyone clarify that this is happening to them too?
I'm coming from an S5 and i thought that was OK, but on the note 4 the battery is awful.
Will see ART out for the day and see how it goes.

In testing ART too but need to run a full week to get a real fell for performance and battery changes.
As for the switching drop, it's normal to lost 15-20% as all apps need recompiling but it's a onetime thing (unless you restart your phone), in which case it'll do the same again. So, don't restart!

Well you had to have restarted when you switched to Art, otherwise the change wouldn't have been applied. That explains your battery drop, so nothing to worry about there.
As for battery life in general, my non-rooted Note4 consistently gets about 5-6 hours of screen time and about 25 hours total run time. Note 4 battery is pretty good actually. Check out the battery life threads for comparison and see from there. Maybe something up with your particular model or a rogue app draining battery.

It was in reply to the previous user who said "Unless you restart"
Anyway, battery life is slightly better, I got 1 day and 20 hours with light ish use, so i'm happy with that, I have turned power saver on though.
And it isn't an app trust me, streamlining a phone is one of my strong points.

Battery life amazing now. Why? You tell me.

I have had the ultimate in crappy battery life since day one with my Vibrant. I have tried reconditioning, task killers, freezing apps, etc., etc. Very minimal gains and, in some cases, worse battery life. These things were draining just sitting on our pockets.
Here's where it gets weird. My wife also has a Samsung Vibrant and was getting the same horrible battery life. We were both charging dead Vibrants half way through the day. Granted, we are both moderate to heavy users but I expected more. A week ago, my wife was still sitting at 80% by lunch time while I was looking at 27%. Huh? I asked her what she did and she had no idea except that she had downloaded a battery monitoring app the day before. I thought it made no sense that this could have anything to do with it so I brushed it off. Over the next few days she was still getting killer battery life throughout the day.
So....I decided to give it a shot just to be sure it wasn't that app. Well, just before bedtime, my battery was it 7%. I downloaded the battery app, plugged in my Vibrant and hit the hay. By noon the next day I was still over 80% I have no idea why but I know it's working for both of us and it has to have something to do with this app.
I'm no programmer and I certainly have no vested interested in any android apps. We just stumbled on this and it works. Would anyone out there have a clue why?
I'm not sure if posting the name of the app breaks any xda rules so I'll wait.
Ever since i've been on JK2 Froyo my battery life has been excellent. But i'm interested in hearing which app you're talking about

I agree. I just didn't want to be seen as peddling a product here.
It's called BatteryTime. It's free although, I believe there is a pay version. I didn't adjust any settings. Just installed it, charged over night and I can't believe the difference nor understand why it made such a huge difference. I unplugged 4 hours ago and have 98%. Still a mystery to me but I'm not complaining.
There's like 4 of the same app on the market x)
What is the full name?
OH and thanks, I installed it, I'll report back with results.

Just Looked again and you're right. There are 4 versions there. I'm currently using the "BatteryTime Lite" version.
The only thing that I can think of to rationalize this huge difference is that the battery percentage was being reported incorrectly before. I may have had a charge that would last all day or longer but it was displaying an accelerated discharge rate which would kill my Vibrant prematurely. For one reason or another, this app appears to have corrected that and the indicator is (I hope) reporting the correct battery life now.
Does that make any sense?

Thanks for sharing. I will give it a try.
Update:
I found this somewhat disappointing. I rebooted my phone for the first time in about a week and on boot up the indicator is displaying significant drain again. I was at 96% before boot and 56% after? I'm going to recharge to full again and see if I still enjoy the same battery life.
Now I'm really confused. Sent an email to developer.
judging by the app description and most of the comments - the app doesn't actually *do* anything. It merely reports the battery differently.
No amount of software will change how much charge a battery can hold. The only thing that's different is how it's being reported.

Indeed, and that was my point to begin with. Originally, the battery indicator reported as critically low in no more than 6 hours. Soon after, the phone would shutdown until put on the charger. With this app I am able to get through the day reporting roughly 30% at bedtime around 10pm. Of course, that is subject to change on a reboot....until fully charged again. This is the mystery.
Yeah, there is funky stuff going on with battery meters. One that is included with the Obsidian Roms is Battery Left, currently, this is showing a 50% charge and 10:19 left. Next to it is Juice Plotter which is showing 21h 11m left. According to the system, i am at 71% Power and it has been unplugged for 6 hours. From experience, I know that the 21h remaining is actually accurate and Battery Left is completely dorked.
The point being, you can't always trust the battery meter.
So I installed a monitor also to try and figure out what was killing my battery 30+% over night and I had the same reaction....I woke up to a 10% loss. I realized what is probably happening is since this app is monitoring the phone all night...whatever app is draining the battery is probably a daemon that only runs when the CPU goes really idle for a certain period of time. More than likely that app inadvertently gave you better battery life because it runs in the foreground and marks your phone as being active so whatever app was killing battery never ran.

I think you've hit the nail on the head. Since day one, I have had buggy battery reporting. For instance, if I reboot the phone while it is plugged in, the reported battery level changes dramatically.
Edit: your later post supports this idea even further.
I installed this on my phone. This program does not attempt to save battery life or control anything on your phone. It does offers "Tips" to save battery life. Its main purpose is to indicate, based on your current level of charge, how long your battery should last given different circumstances - ex. idle, talk time, video time, audio time, etc... Thus the name BatteryTime.
That's all that it does. Any perception of a longer lasting battery may have been an anomaly as does happen sometimes with our phones. One day you'll seem to be getting awesome battery life (and there is likely an underlying reason which we'll never figure out, but which jives with the battery) and the next day it is back to draining quickly as normal.
There are three certainties in life: death, taxes, and posts about battery life in smart phone forums.
Anyone have the issue where they charge the phone overnight, the phone reads 100% in the morning, you unplug it and you are immediately down to 7% battery? It seems to happen to me at least twice per week. It is a terrible bug.
i dont get it you said that before the battery wasnt being read correctly so it shut off fast but now with the app it reads correctly and last you the whole day with 30% left to spare?? wouldnt that technically mean it increased battery because you got it to last all day plus some? just by making the phone read the battery correctly.

[Q] Battery life?

I apologize if this was asked before (I did a search of the forums but nothing really came up), but I'm wondering what others' experience with the battery life of the S4 is? This is my first smart phone and coming from a non-smartphone, I'm not sure if my expectations on battery life are unrealistic.
I got the S4 on 4/29 and brought it through one full charge cycle and several part cycles. Battery life is pretty important to me so I put an all black background (since its AMOLED), keep the brightness to below 10%, turn off all the fancy sensor things, turned on power saver mode, turn off wifi and data unless I really need to use it, turn off all sync so it only happens manually, etc. Yesterday, I charged it to 100% to see how long it would last and the stats I got were:
At 6% battery left, I had a total screen on-time of 2 hours and 58 mins and 1 d 2 hr on battery. Then, when I charged it to 100% and took out the charger, after about 5 minutes of it sleeping/screen off, the battery percentage dropped down to 97% with no data, no wifi, no active apps running.
With my pretty battery-friendly settings on my phone (or at least I think so), is this battery stat normal to others with this phone? Or do you think something might be wrong with the battery?
That sound horrible. There must be some rogue apps running/some wakelocks - try using better battery stats and find out.

For a smartphone, an 'all-day' battery is fine, and given that the S4 has so many sensors, large screen and a powerful processor, I am happy with the battery lasting for 12-16 hours. I don't turn off any sensors, why get an S4 to run it on power saver mode and turn everything off? It defeats the purpose, in my opinion. I am trying to use as many features as possible on my S4. Of course, there are a few I don't, but just for personal preference. What you are doing is (no offence) in my opinion like getting a BMW M3 and running it on 4 pistons to save fuel.
Anyway, your battery life will improve after about 10-15 charge cycles, I noticed that with my past phones as well. If you need your battery to last longer, I would suggest getting a spare battery and keep it charged at all times for any emergencies. These are some of the reasons I love Samsung, removable batteries and microSD card slot.
thanks for the replies guys. I'll try the betterbatterystats app out. i'll probably take it back to sprint and see if they'll replace the battery for me. the screen accounts for about 50% of the battery usage in the stats and other apps take up the rest. the battery curve is pretty linear in a downward slope too (except when i don't use it at night, it becomes much flatter, albeit still downward).
haha its funny you say that, because i agree completely. the m3 is my dream car and if i could ever afford one, i would probably baby the crap out of it the reason why i got the s4 (and i also compared it to the htc one as a possible candidate) is because of the removable battery, sd card, nd most importantly: camera. that 13 megapixel shooter + hdr is really great for good photos on the go. speaking of which, i use the camera alot. is the physical use of the camera and the screen use a big power hog?

The phone only takes 1h 57 minutes to charge from flat. It's mad how fast thing thing charges from AC so battery life isn't really a problem. (yes I was sad enough to time it)

Battery life MUCH worse than Z2

The Z3 is a nice device, I enjoy the screen, thinness and weight, but the latter two definitely come at the expense of battery life.
Of course the faster CPU also plays a part. I'm just getting 3 hours of on screen time with my usage out of it. On the Z2 I got 4 hours.
I don't even know what these people do who get an insane 10 hours of screen on time out of theirs. Probably different kind of use, but still...
Once again I need to look having an external battery with me.
Disappointed.

Post your battery stats page. Seems odd to me. I have 2.5 hours of on screen time with 10 hours on battery at 78% at the moment.
I noticed that too since I switch from Z2. Its difficult to see from the power management tool indicating how many screen time ect.. the battery life just don't seems to be better then z2, and results and very random.. sometimes better then z2, sometimes worst then z2. Perheps firmware upgrade will help..

I have rolled through 3 Z3s due to defects on my 4th, all had great battery life up to 8.5 hours SOT, lowest is about 5 hrs SOT, before calibration. Give it a few charging cycles, or do a full charge and full discharge then recharge and use. You should then be fine. If that does not work maybe you got some errant apps or lots of them continously syncing. Also go to backup and reset menu and disable data logging.
been averaging a day and a half with over 8 hrs SOT with mine. mix of wifi/lte
I don't know how you guys do it. I always get around 3 hours SOT, no matter what. I wish there was a way to check wakelocks without root.

I think it has something to do with the apps you use.
Facebook, facebook messenger, snapchat, swiftkey and Nova Launcher gave me from 4+ estimated days (in stamina mode) to 1 day and 1 hours.
If I don't play games, I get between 6 and 8 hours SOT at the moment.
Check that google play services aren't burning through battery.
Should never get 2 or 3 or even 4 hours SOT unless you're playing games.
I use screen brightness on about 80% as well.
I'll be posting my power usage screenshots soon.
Off to the top off my head, screen was about 50% of power (with automatic brightness, and the slider set on the 1st third), the most power hungry app took about 25%, with the rest taken up by various other processes and apps.
WiFi off.
Facebook used to be a battery killer, I don't use it, but check on that.
Z3 has an incredible battery life
there's something wrong in the op
For my baterry stay perfectly (often 20% for system 20% standby and 50% screen)
Even if it's Facebook that eats 25% of power that still wouldn't account for the overall bad battery life.
Nope mate, sorry - my battery life is out of this world. It's not the Z3, it's your device - get it tested, re-flashed or inspected if the problem persists.

Oh no I already removed, I do not have any battery issues, I was just giving a tip to OP.
Right, so here are my power usage screen shots.
I don't think these can be called ok in any kind of scenario.
I would like to add that with my Z2 I didn't ever get up to the 6 or 7 hours other people were getting out of it, but with my kind of use I got 4 to 4.5 hours, which is considerably more than I'm getting right now.
I supposed it's kinda obvious, with a faster CPU and a smaller battery. What else could have happened. It just annoys me that Sony tries to tell us that battery life is BETTER than on the Z2. It is not.
Well, reviews uphold/confirm Sony's claims so its probably not the phone itself per say. I get 7-8.5 Hrs SOT easily. Disable autosync when un-needed and location services as well. Then see.
Just as everyone suspected, it's malwarebook causing abysmal battery life. Remove it and watch your phone get tons more battery.
Considering that you're one of the very few, if not only, getting poor battery.....I have no idea what else it could be. The phone get's better battery because of using the 801 SOC instead of the 800, which sips battery like fine wine, leading to the increase in life over the z2.
Malware.... Yeah, whatevs.
Fact remains that with the same usage as before my Z3 performs worse than my Z2, so there.

Verizon S7 Edge terrible battery life

First time posting. Bought two new S7 Edge phones in late November. My wife can go a day or two or three without charging, similar use with hers. I am lucky to get maybe 6 hours ever since I bought it. I don't use it for gaming, I use social media, email, news, some music, take a lot of pics of the kids, Photoshop, reading, research, etc. My phone is my laptop replacement.
I installed CPU-Z a while back because my phone is often hot. Sensor readings often exceed 150° F with battery temps exceeding 105° (with very little activity).
I've tried charging with rapid charge disabled, decreased screen brightness & resolution, shut down background processes, did malware and virus scans, factory reset, etc. No change.
I do have many apps installed on my phone and I have moved as many as possible to the 64Gb micro sd. No difference. Looking for suggestions. Is this a defective phone? Should I be looking at a replacement? My Note 4, Note II, and Thunderbolt all had much better battery performance.
Your help is appreciated.
I can get like 10-11 hours, did you check "Battery" section to see what is draining her ?
Well I can get even 12h of sot so I don't know how can you get such low battery life. Also, if it heated up to 100° Celsius the battery is not healthy anymore,you should change it
There is absolutely no way that U can get 12 hours of SOT on official rom and with average usage. Don't confuse the OP.
About the problem,
Did U try factory resetting the phone? That should be the first thing to do when the battery is draining abnormally. Also. send us pics of battery usage.
Sorry for the late reply. Apparently I turned my notifications off.
Yes, I have done a factory reset twice in the past few months. I think I'm going to backup in the next week or so and do another one and this time try installing only a minimal set of apps for a few weeks and see how it goes.
Here is a screenshot of my current battery usage. I charged the phone twice today. It's actually doing ok at the moment, usually android system uses the most juice.
Also a shot of the current temps.
Thank you all again!

AOD huge battery drain

Hey guys.
So I noticed everyone here and anywhere else basically, complaining about the battery life on this phone after the MIUI 11 update so I used the debloater directly after getting the phone to have the best battery life possible.
Turned off all the suggested apps and services and I gotta say battery improved, but it wasn't what was promised by the phone's specs. I'm barely getting 4h SoT, without any heavy usage whatsoever, only social stuff.
The culprit for me as well has been the Android System, with over 40% drain every day. So I installed Accubatery to try and see what's happening with my battery, along with better battery stats.
What I found useful from the accubattery app is the permanent notification where it tells you, after a few seconds, how much mA will be drained in an hour of using the phone like the way you are using it at that moment. So I did a test. Had my phone on the home screen, doing nothing. After a few seconds the reading showed -180mA, which is awesome right? Then I locked my phone and left it at the always-on display for a minute or so. Unlocked it and the notification showed -980mA.
This is very VERY weird and I cannot find anything anywhere suggesting what anyone can do to combat this. I have more average battery drain when the screen is off than when the screen is on.
I have never reset my phone (and would like that to stay that way if possible) and the phone itself is a month old. It's really saddening to see other people are getting twice as much SoT.
Do you guys have any suggestions?

I was on Miui 11 for a few weeks and had ~8h SOT with AOD enabled all the time. Now I am on Pixel Experience and I have ~7.5h SOT without AOD so I am very satisfied with the battery life.
I advise you to wait for Miui 12, which will come very soon to the Mi 9T. Then everything will probably change again with the battery life...
