Battery life worse after factory reset - Samsung Galaxy S7 Edge Questions and Answers

I had to factory reset my phone after an issue, beforehand I was amazed at how good the battery life was, and after it is just bad...
I can't see anything significant taking up the battery usage, it's just worse
Any ideas on what can have caused this, or how to check myself?
Thanks

Yes i have same issue now. I get S7 edge 4 days ago,yesterday rooted and flashed twrp (for this i had to make factory reset) and after that my battery life is very bad too.. before that it was very good. Really weird,hope someone can help Regards.

Same problem here.
More than 4h of SOT aren't possible anymore... :crying:

R u guys giving a could days after reset to let battery life settle down?maybe try clearing the cache a few times before factory resetting in recovery mode

Is it likely to get better again then? I reset mine on Saturday...

I made dalvik and cache wipe yesterday night , let see how will be battery after few cycles.. then maybe i will go for custom rom

Can you do that without root? If so, how please?

If you have recently wiped then please allow antiquity time for your device to re-learn.
Without going into detail.
Linux is a complex system, that does memory management very efficiently.
When you wipe, you have removed all its information it has retained about applications.
What to stop running, What to allow idle.
Honestly allow a week on normal usagage before you see a increase in battery life again

OK thx, will do
In case it doesn't sort itself out, can non-root users wipe cache?

Perfect, thanks!

And to confirm that I have formatted my S7E several times but I do not see any significant decline in battery life. I get
5+ hours of SOT on an average (Sometimes 6 too!)
14-17 Hours of Total Usage.
I am rooted, but on stock Rom.

Battery still poor but not been a week yet (although Factory reset all my devices regularly and never seen this issue before)..
What I've also noticed is charging appears slower too, and when using my gear vr, I'm noticing a little overheating which didn't happen before.

[Q] "system_server" High CPU Usage and Battery Drain

Hello! I recently started having big problems with my battery life. I have a Verizon galaxy note 3, with safestrap and Hyperdrive ROM installed. A few days ago, my battery started to drain much quicker than normal. I looked at the battery info, and saw that the android system was using the most battery by far; even more than the screen. I then saw that my CPU usage never dropped below 70% and usually hovered around 90%. Next, I went to developer settings and looked at the CPU processes. I saw that "system_server" was using up most of the CPU. This persists through a reboot, and drains battery life incredibly quickly, about 15% per 20 minutes. Does anyone have any suggestions or experience? Thanks.

Try clearing cache and dalvik cache.

Thanks for the reply. Unfortunately, this did not help.
i gotta same problem, i think only one solution (except factory reset) is to flash another kernel..

I am having the same issue.
I have a Samsung Galaxy On5 and it's rooted. The "system_server" keeps asking for superuser permission which I keep denying. I don't know what this is exactly but I just want to know how to get rid of it if possible or if anyone has any suggestions I'd like to hear them.
This forum is Note 3 not your phone .
Super su remove it but you may loose root .

Sudden Death Syndrome?

This morning I had my note 4 turn off and freeze whenever trying to get past the boot screen, this was happening for 3 hours and finally it turned itself on fully without pressing any buttons after leaving it alone for another hour.
Why would it do this and will it be a problem in the long term?
I have the SM-N910U variant and have CF-AUTO-ROOTED it

I've wiped cache and davlik cache but don't want to full wipe at the moment as I'm out of town and the only internet I have is my data plan. The problem hasn't happened again yet and I hope it doesn't.

Cache and dalvik could possibly fix your problem, but a full wipe will have a better chance at fixing "bootloop'" like issues. Try it when you get home!

The battery drain is CRAZY, what to do?

Just 1 hour of screen on time with a little bit of Twitter, 62%.
What to do? The battery drain is just CRAZY.
The device is disconnected since 6:30, now it's around 12:15.
There is other stuff that drains battery excluded from that list. Facebook-things is one of those and it drains heavy battery. If you can live without this "social spyware" - disable the app!

Hey, I'm not using Facebook apps (except WhatsApp).
Everything of Facebook is disabled.
I would say your 4g reception is bad causing the phone to use more power to get you better signal.

I don't think so, the battery drain started before just one week.
The latest marshmallow update has screwed around with my s7 edge too, heavy drain etc. I reverted back to the previous build (download the correct one from SamMobile and flash it) and battery was back to normal.
Before doing that, try cache wipe from stock recovery. This cna help in some cases.
Now I've flashed the nougat beta and battery life is great again.
The problem is your router
Can you see if access in deep sleep?
Test with CPU Spy
If it was this bad for me I would just factory reset it dude and wipe the cache.

Nougat battery drain

Hi,
Am I th only one that is getting this ridiculous battery life. I am barely going over 2 hours of SOT and maybe 8 hours of battery with light/medium use. Clearly something is off. I did FDR and wiped cache.
Any ideas?

Are you using facebook/snapchat? Most likely reason, post screenshot of battery usage or no one will be able to help.

I do use facebook from time to time. I can't post yet unfortunately. Hopefully you can view the image I left a link for underneath my original message.
I use snapchat and facebook disabled. A bit drainy though even after f reset.
No issues here. Seems the same as MM to me. Maybe just a little more than normal. It was bad at first but began settling after a few days.

Few suggestions,
Firstly I did was install battery stats app and check if you can find whats eating batery
If that doesnt help I would say flash firmware with odin including data(Backup before this). After that do an Full Reset and then try.
Since This is complete OS upgrade it will help clean lots of things. I am getting 5-6hrs SOT. All the best

I've had *SIGNIFICANTLY* better battery after disabling the stock FB app and instead using Metal for Facebook, and it has a dark theme!

I had terrible battery life initially as well. So I did a factory reset and...battery life still sucked. I think that was because I allowed Samsung and Google to restore my apps and previous app data. So, I did another factory reset and a completely clean installation of all my apps (no Samsung or Google-assisted restoring of apps). Since then, battery has been back to normal, which for me is about 4 hours of SOT.

Same here. I did a clean app install also and that helped. The only thing I allowed to be restored was my gmail calendar and contacts.
Yeah my upgrade made my phone glitchy and half the battery life I used to get. But on the plus side my phone doesn't run as hot and lock up when downloading large torrents.

Horrible battery drain on s7 edge nougat. Attached battery status from BetterBatteryS

Hi guys, really need some help on this.
After upgrading to nougat on my Su edge intl ver (exynos) SM-G935FD.
The battery has been horrible. From what I see in BBS it's always awake and running on max CPU state. Attached the ss... Please help me.
I've tried the following:
Clear cache using recovery mode
Cleared permissions
Disable Google play services (causing many other Google apps to fail so I enabled it)
Turning off wifi and location
Using data saver
Using battery optimisation
Using greenify
Tried the above methods solo, or a combination, all which failed to help.
From what I see Samsung pay is causing the problem. How do I solve this? It's an integral part of my life (really convenient). Thanks all in advance!
Update:

Well, successfully reverted to older version, looking forward to better battery life. Used Drodviews.com for firmware files and Odin V 3.12

Worth a try...
Try to disable some apps or if your phone is rooted delete them. Clear apps permission or references or wipe factory reset through recovert.

I have tried disabling apps like Facebook, messenger, Instagram, etc but no avail. Permissions method also tried. Reset all settings tried too.
I'm only left with factory data reset which I'm unwilling becaue Samsung cloud doesn't seem to be working properly.
I have the same problem too. I noticed that after the Nougat update my phone started to live twice shorter after recharging (1 day instead of 2). Couple of days ago I installed AccuBattery app which shows me that my phone lost almost 25% of its battery capacity :/ Don't know what to do. I am curious if I can ask for a battery replacement from Samsung service (warranty) or not.

I'm not sure too. I might try soon after I have more free time on my hand.
I tried reset settings and so far BBS doesn't show samsung pay alarm wakelocks anymore. I'm gonna monitor for a while. and see how it goes because I still feel that the battery life is pretty bad...
Well I haven't tried any of the battery monitoring apps, but after the Nougat update my S7E shows me 15 hours and 5 minutes remaining right after unplugging from a wall charger.
well batterys have a capacity, there are number of charge cycle after which the battery doesnt stay healthy and the backup gets short..... After nougat upadate I have noticed battery drains but not that aggressive like yours.. You can factory reset you phone once and chk if samsung pay is still sucking battery...

Not very accurate. It is based on current usage. Use gsam or betterbatterystats to get an accurate read on your battery usage.

The latest update also reduced the battery life of my phone. I did a factory reset and things have improved, but still less overall battery life compared to the old firmware, might revert back to it.
Did you try using custom rom?
On rom that i using battery life is amazing

Try this. Charge your phone after disabling fast charge. I.e charge it in normal mode.
I have seen that the baterry lasts much longer this way.

It is possible, but might interfere with the rom's cache data and i don't think it will perform better because of that. So a factory reset is usually needed when reverting.

I'm going to try reverting tomorrow, will see if it happens and post here if successful.
