How to know if my battery/device is performing at its best? - Android Q&A, Help & Troubleshooting

Hello all,
I just bought a galaxy s7 edge duos and I would like to know if there is a way, perhaps an app, that can tell if there is something wrong with my device.
I want to know if my phone's battery is performing at its best. Right now, it lasts almost 24 hours with an average of 4 to 6 hours on screen usage. I mostly browse the Web, chat with whatsapp, and play boom beach and clash royale for 30 to 45 minutes a day. I think it is consuming too much battery when idle, like one percent or so per hour.
I would like to read your opinions.

Bumping... please help out

Look into a battery stats app. But you will find that it's whatsapp draining your battery. Facebook apps are all well known bad apps for everything from performance to battery life.

amaze vs galaxy battery life

i have a galaxy and im getting some ridiculously good battery with custom rom, im at 10 hours with over 50% battery with moderate usage, i was thinking about switching to amaze because i really need led notification and camera button, can you guys let me know what the battery on the amaze is like how much usage and what percent u have ? i know itll be worse then the galaxy i just want to see how it will be to help me decide
I'm still figuring out exact battery life times, but I'm getting about 5-6 hours with very heavy usage (screen on for about 2 hours total according to battery use).
I'm at 9 hours with 12% left. I'm running unrooted totally stock but with Juice Defender Free on aggressive. Fairly heavy usage since I just got it yesterday and am constantly playing with it. That usage includes 60 min with My Tracks (gps) and PowerAMP running while out waking the dog. However I did have it connected to my pc for about half an hour while i was transferring music.
amaze
damn thats not looking good, anyone that rooted and installed one of the roms get better battery ? because 9 hours with a battery app doesnt sound too good, im at almost 15 hours with my galaxy and i have close to 50% battery left, with moderate usage (some facebooking, lots of text, emails,15-30 mins of gaming) not going to lie the battery on the galaxy with the rom i have is kind of ridiculous, best ive seen, but if the amaze can at least hold for 16 hours on moderate use on a full charge or 12 hours on heavy id be happy

im getting like 18 with my custom rom
with heavy usage ? beastmod on the amaze right ?
im on quiksense right now heavy use like wifi teather for a hour and a half i get like 9 hours - 10
but wouldnt it kill more battery if 4g was on the whole time ?

it was along with wifi sharing so that was a lot of power being used
ok
ok thanks, how many hours do you think youd get with music, several facebook notifications, lots of text, several emails and maybe 10-15 minutes of gaming and regular widgets ?

ok sounds good, you guys have any small problems with the amaze that your facing ? like the galaxy has the blob problem which is common, u guys have any similar known issues ?

Battery Life Span

Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!
Read forum for more details.

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.

Is my GS7E battery life okay?

Hello.
Im curious if the battery on my GS7E is upto par. With a complete discharge, im getting around 5 hrs SOT and a total battery usage of 24 hrs. Im not a heavy user. I only browse the internet, whatsapp, messenger, fb, YouTube and some minor games. Out of 24 hrs, the WiFi is turned off for like 5 hrs. Other than that, either the WiFi is on or the Mobile Data. I have the G935FD model.
Any help will be well appreciated, thanks!

Exynos battery life

Hello all ,
I was about to buy an Exynos model and read somewhere on here that there was an update to fix battery life. Is this true and how much has it improved ?
Thanks
Personally I see much better battery life after the April security update. SOT gets about 6 hours of normal use.
i still haven't received the latest update, but my battery life is great
i get 8hrs of SOT
ARD 4 is latest firmware ?
From wich country ?
Tnx.

Latest security patch, i.e. 1st April 2018
Reading Anandtech article, exynos does not seem to be a good choice unfortunately. I have read all about it after my devices was shipped today, might return it.
I will tell u the truth, i have snapdragon and 5 hrs of SOT , since 1 month so the battery life is almost same
5-6h SOT with 2 days of usage between each charge. But depends heaviliy on your usage.

Thanks, this is not bad at all for an exynos. This is really odd as some users claim they get much less like 3 hours SOT and 16 hours standby. Are you on BER5 btw.? Thanks

Yes, i am. I also changed some settings of the device and disabled a lot of apps to save some power, but im not using a power saving mode. Standby drain is still a bit high though with 3-4% in 7h.

I'd like to know if you guys are using Facebook and Messenger apps. Tried it on a brand new unit without logging it in and the standby drain is less than 0.5% an hour. Installed those two because I actually need the Messenger (can't seem to greenify Facebook) and my standby drain is like 2% per hour.

Nope, i do not use Facebook at all, only Whatsapp and Telegram. Facebook is known to be a battery killer. But i think there are official lite apps which significally reduce the power drain.

figured as much. I just envy how you can use those two because your contacts aren't dependent on Messenger.

With Messenger you mean the Facebook Messenger? Well no facebook, no friends at facebook to chat with .
I just dont like this company at all. The idea behind it is really cool, keeping people connected. But what they do with your data isnt. Not a tiny bit.
And if the trend goes on, WhatsApp will also be uninstalled someday. But this would be hard, since nearly no one uses an alternative messenger.
Whatsapp does the job for me and its much easier on the battery.
But back to the topic: Have you tried this Lite app?
Should be less stressfull for your battery.

Sounds a lot like my usage, also the settings you have done. Did you also disable 4G active while on Wifi? Its hidden in the developer settings.
Otherwise im currently ~32,5h off the charger with 42% left. My screen usage is at 2h 22min, so maybe 4,5h overall in this run. But its not too bad cause of the overall runtime, as standby also drains the battery.
If im pushing the battery more without trying to achieve 2 days i have no problem getting to 6h of SOT.

That sounds very similar to another poster here who is also having issues with dual sim battery drain. He also made the same comment about having better battery life with other "top of the line" phones. Interestingly, I thought you posted a screenshot of 8+ hours SOT with the exynos recently (and 15+ hours SOT with the snapdragon). So I suppose those figures weren't a good reflection of your "average" SOT? As now you're mentioning only half that SOT, despite quite a few tweaks too.
Question - it sounds like you have around 9-10 hours where you're not actively using the phone during a typical discharge cycle. Do you have a sense of what your hourly standby drain is (I asked the same question of the other person having issues and I think he mentioned about 1% or less drain per hour)? A good way of observing it is leaving the phone uncharged overnight. I'm just curious as to whether your relatively poor battery life is mainly due to excessive standby drain or excessive drain despite only doing light-moderate tasks. I ask this because, in my experience (and also with people like Galaxo60) and demonstrated in numerous battery drain video tests, heavy use (eg. GPS navigation with high accuracy) tends to drain the battery by around 10-15% per hour and very heavy use (complex games, video calling) tends to drain the battery by 15-20% per hour.
Assuming a standby drain of 1% per hour (which is on the high side with AOD disabled and a good wifi connection), you can see that even if you played a complex game for 2 hours (40%), then an hour later (1%) you did a video call for an hour (20%), then an hour later (1%) you spent 2 hours navigating Maps with GPS on high accuracy (30%), and then you went to sleep for 6 hours (6%), your battery would be down to about 2% over a total of 13 hours on battery with 5 hours SOT. I'm probably giving the high side of the estimated battery drain in each task too. And this should be without any significant tweaking (based on my experience, and unless those video tests forget to mention tweaking etc). It sounds like you don't do any of these heavy or very heavy tasks, and therefore your SOT should be more like 6-7 hours over 20 hours or so (just a rough guess to make the point).
So assuming your hourly standby drain is also around 1%, then the only thing I can think of is an app that you're using or a task that you're doing (or some specific combination of apps/tasks that exynos doesn't like?) that is draining the battery more than it should. Or throwing in a wild speculation, somehow there's a built-in kernel backdoor that activates while your screen is on and is secretly doing something that drains your battery more hehe (and of course doesn't show up in any battery stats).
I know the occasional poster has also mentioned having only 1-3 hours SOT, so you're not having the worst reported SOT I suppose. It would be interesting to know what the hourly standby drain for those people etc is too.

Where have you seen me posting 8+ hours with the exynos? It was of 6 hours and 50 minutes in the "screen on time" thread achieved when additional battery saving steps like bk package disabler disabling huge chunk of services and apps and keeping location in power saving mode. (bk no more working as it's removed from playstore and I went for factory reset after BRE5 update)
4 to 5 is the average sot with 13, 14 hours with few battery saving steps. No wakelocks no battery hogging applications.

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 Samsung Galaxy Note 9'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!
I might be tripping but my Note9 Doesn't last as long as my OP6. I run the same apps and similar settings and my note last me about 5-6 hours my OP6 Last 6-7 hours. All this with heavy usage and the OP has a lower battery capacity.
I feel like heavy use and light use consumption is around the same and get 5-6 hours SOT regardless. Browsing and using the Samsung Music app seems to drain around 1% every 5 minutes. I was expecting the battery to drain a lot faster with games but it's more subtle than I thought. Yesterday I didn't game much but used S-pen to take notes, and got 6 hours 21 minutes SOT with 6% left, within 10 hours of total usage (resolution was QHD+ most of the day). Today with some heavy gaming (Real Racing forced to QHD resolution with Game Tuner, as well as Bowling by Jason Belmonte, Alto's Odyssey) I got around 5:48 SOT in 11 hours 25 minutes (started to reduce the resolution to FHD+ around 30%).
I'm going to kill the battery in my Note 9, eventually. It's my daily workhorse. Multiple Gmail accounts, work email, continuous use throughout the day, 3 games that I check upon every hour and a half... Should last about a year by my estimate. Oh well. Phones come and go...
Heavy use endurance is okay in this phone but light usage endurance is not good. You lose %15 in a hour just by 9gag browsing.

Sadly, samsung put a lot of effort for this not to happen. Right now it's not really possible outside of a friend that don't play fortnite and lend you his phone to login with your account and play atleast 3 full matches.
I find camera and SoundHound to drain a lot. I can barely break 4.5-5h SOT if I use the camera for over 50 minutes. The other day I was trying to see if SoundHound could identify songs from my bad singing while wireless charging and the percentage actually went down.

IMHO, the fortnite skin you get is garbage. Should have given in game money instead. Or at least pub g. I play both on my N9 with the latter getting more SOT
Recently got my Note 9 a week ago and battery has been about average as compared to my last phone. I can last 5-6 hrs of heavy use and 7 for light use. Mind you my last phone was the Galaxy A7 (2017) and battery on that thing is nuts. 7 on a heavy and 8-9 in light use. Might probably due to I game more on my note rather than my last phone.
Off topic question, was playing ragnarok mobile on my note while fast charging when I suddenly fell asleep. Woke up 4 hours later game was still on and the battery is now at 83%. Will this massively damage the battery of my phone?

Fast charging works up till 80% then it will switch to normal charging (and the 80-100% are always different charging method that is slower + better for the battery longevity). You are fine, nothing will change about your battery health. I would be more concerned about burn-ins/burn-outs, but you played most likely at lower brightness and surely not in overdrive mode = you will be just fine too.
Edit: also I forgot to mention that samsungs don't fast charge when the screen is on, only when the screen is off = it charged slowly normally and that's why it reached only to 83% (as because of the battery use, the actual + in the charge was lower than the 2A in normal charge/~500-1A in the last 20%). All good, as I said, don't worry.

Note 9 has a big and brighter screen and a lot of bells and whistles
I guess that makes sense. The bigger brighter screen could be the culprit.
I can go a day (8am to 12pm) of moderate-heavy use with some battery left over. I'm taking 5-6 hours of SOT (WhatsApp, Internet, RadioPlayer Canada, Google Maps, Twitter, Fallout Shelter). This is despite the phone not being entirely optimized for battery life besides using the Device Maintenance feature (I have wifi and data on, bluetooth, location, high resolution, automatic brightness).
The battery actually kind of sucked when I first got it lol. But it randomly improved a lot.
My SoT with heavy usage is just amazing 6-7 hours without a problem!
Has anyone used the dual sim always active feature? Im assuming it drains battery far faster, especially with extended use
ok here is the deal. games will drain the battery less than previous phones do to more efficent cpu.
however anything else didnt change at all or got even worse.
any wireless connection, sensors, screen (even worse), will be the same as in any other phone. so this is where the battery kicks in and gives us a bit more leway. yet it ahs to compensate for the insane screen. so our SOTs are pretty good.
biggest issue is google and google services as usual. with their insane collection of data we litereally pay for them collecting our data. and thats not just a little bit, its over 1000 datapoints an hour.
that was the main reason i wanted to switch to apple, but after a day in hell i gave up on the fruit ****show. way to many compromises.
however at the end of the day what really kilsl the battery is energy for the screen itself and all kind of data connections.
the cpu cycles are laughable for most games, those cpus are powerhouses, almost PC level
so turn of wlan, turn of gps whereever you dont need it, same for bluetooth, cut down on syncing services as much you can this helps a lot.
also gmail is aweful in their push services. i tossed it out, i run exchange active sync and its fine

How's your screen after the 22 hour marathon? Any screen burn in? Ghosting? What brightness do you keep it at?
