[Q] Battery life getting worse - How to check for draining apps?

Hey guys,
A common question: My Nexus 5 seems to suffer from energy drainage, as I'm not getting the Screen on Time I'm used to. Ever since I got the phone, I've always got about 2:45 - 3:15 hours of Screen on time and in the past months, that hasn't changed, until the last few weeks, as I'm getting a max up to 2 hours of screen on time, often up to 1 and half hour..
Not much has changed. Same usage patterns, not really any new apps that I regularly use and screen brightness (50%), Wifi (24/7 on and won't turn off on sleep, 90% of the day on WiFi), 3G (normal use), GPS (off), bluetooth (off) I use on normal base.
Also the usage graph that shows how many % per app is used hasn't changed ever since. 25% screen, 15% android OS and all others a few percent.
So I'm unsure what app/thing is the boogyman, or how I can check what is; hopefully any of you can help me!
I wouldn't mind a factory reset, but I'd prefer trying to use on-device checks before I perform a factory reset.
Thanks!
P.s. I'm not rooted (yet, still unsure whether to or not. Kinda happy with the 3 hours I'm used to. Not interested in a different rom anyway), so no answers that require being rooted. Thanks!

If you're rooted you're going to want to use Better Battery Stats. I believe there's a version free to XDA members, somewhere. It'll give you extremely detailed information about which wakelocks are eating up your battery. There are a ton of threads on here (my favorite is in the Samsung Skyrocket forum) which explain the various wakelocks and how to minimize or get rid of them. If you're not rooted, I'm not sure what would be able to help.

Not rooted - Updated the OP. Thanks anyway!

Do you have anything running as a service in Settings> Apps> Running that wasn't before? It might be the latest Google Search or Play Services updates.
Could also be strength of signal or if you were traveling more than usual. Any number of things, not much we can do without BBS or Gsam stats which would require root for meaningful results. Otherwise you could screenshot your default battery stats including the graph, screen on time, and detailed stats for any apps using more than 5%.

Any links to the better battery stats thread? I'm having similar issues. Running the latests Beanstalk

You should check social apps setting for repeating sync; Facebook, twitter or skype..

Without root and gsam or better battery stats.....this thread will just be full of guesses I'm afraid.
Have to see your Wakelocks. Otherwise no one knows the issue. All guesses.

S6 Battery Life - Terrible

I've been using the TMO S6 for a couple weeks and my battery life is terrible.
I have used greenery to hibernate everything I can, but as you can see in the attached picture the Android system is running overtime. I am lucky if I get 4 hrs of battery time. I also have the screen brightness set to less than 50%.
Any suggestions would be greatly appreciated!

I have no idea why google thought it was a good idea to make battery stats less accessible in kitkat and above, so it's hard to find what causes it. It's probably easiest to factory reset and start clean and then start adding a few apps at a time, to see if you have one misbehaving one

Thanks. I am able to see the apps and utilization using gsam battery app, but unable to look at which android system apps are draining/running, as per the picture.

Turn off WiFi calling and voLte

The problem is that when app X hold a wakelock it doesn't show up under app X but under Android System!

I agree, battery life in general is a huge step back from the S5.

Factory reset then do these two. Also, disable T-Mobile bloat then use Greenify or Shut App.
I can get about a day and a half or two days battery with very minimal use. Don't expect to get more than 4 hours screen on time with this phone. Average is probably around 3.5-4.5 hours but you SHOULD get at least a full day's use with it.

Wifi calling pretty important for some of us

Hi guys I'm using s6 for few days ...battery drains too quickly. ..pls help me need help ...after one call or one song battery drains 2-3% ...I'm too upset pls temme what to do ...would be great if ul help

Battery drain fix

Noticing your Galaxy S6 battery is draining too fast? This thread can help.
Part of the problem lies within a memory leak which is a known problem that Samsung is aware of and is reportedly patching in an upcoming update.
The other issue is Samsung attempts to load everything into memory and run several services in the background as well as hard loading the phone with bloatware.
Here is how I gained 30% better battery performance. Guaranteed
*Prerequisites
*Need to be rooted for every tip to work.
1. Disable anything you consider bloatware
2. Go to settings then application manager and disable both ANT radio service apps. You don't need this. Causes massive battery drain. Google it if you don't believe me.
3. Go to the app store and download "Servicely" from Franco. Paid app but worth the money...trust me. (Need root)
4. Once in servicely add running services and apps to your hit list, choose start at boot and run hit list while screen is off.
5. Reboot your phone. Give your phone a full charge and see the difference
Attached is a screenshot of realistic usage. I was on a poor lte signal for 9 hours and conducted several calls and used my phone moderately heavy. As you can see i got through my entire work day and still have 6 hours left at moderately heavy use.
Remember, this is realistic. I could have shown you a screenshot showing 18 hours left after only using it 1 hour. What I'm showing is a legit 9 hours of usage. Before I made these tweaks I would be at 10% battery or less after nine hours of the same usage.
Post your screenshots after 24-48 hours and let's see how much you are saving.

A shot showing your phone call, screen on, and deep sleep times would do a lot to bolster your claims. Your "normal" use isn't like anyone else's. I have 50% battery left right now, after 13 hours of my "normal" use. I'm not using servicely.

Fair enough. I'll post a screenshot using Gsam

Just experiment. I'm offering up a known legitimate way to reduce battery drain.

I decided to uninstall ANT. Not sure if its just me, but after just a few hours I think I can tell a difference already. The battery isn't just dropping like it was, especially when idle. I'll post my results from my full day tomorrow.

Awesome. Let all of us know how your battery drain is doing tomorrow

Thanks for the tip, it's funny I installed the Sac23 rom which is pretty debloated, I'd assumed this ant radio would be removed but never really checked, surely enough it's still there and active.
My battery has been noticibly better with Sac23 rom from stock but looking forward to seeing the increased benefits of disabling ANT+.

Are these the only 2 ANT apps we need to disable?

Samsung Galaxy S7 Battery Life

Hi,
It has been a week since i bought my s7. I was not quite pleased with the battery life. It was just ok. But now it is getting worse.
battery is 10% at the time of writing this.
Total usage is 22 hours
Screen on time is 3 hours
Android system is taking 23% battery
Screen 19 %
Facebook 17 %
Is this normal? I was expecting atleast 4 to 5 hours SOT?
I have the AOD turned on. Sync is always off. I dont even have the mobile data turned on. I mostly use wifi for facebook and browsing.
Any suggestions on how to improve it?

Aod takes 1% in 1 hour. Facebook takes too much but its known issue. Facebook knows that too and making fix right now. You can disable and enable it and then it will be ok.

Though I own a S7 Edge, the following is from my experience with Note II & S2. I am not facing this with S7 Edge.
When I get a new device or get updates, I do a factory reset and start over. Just clearing the cache doesn't help.
I am using Package Disabler Pro to disable apps when not required and it doesn't require root access.

Disable aod. Aod doesn't let doze kick in. So idle drain with AOD is 2-3% per hr.

Hello, I'd like some help about battery drain too.
I've been using my S7 for 4 months and never made factory reset after the OTA updates.
Today, for example, the battery level fell down from 100 to 43% in 6 hours.
I've taken some screenshots from battery usage screen and the items described inside de Android System item, which is the most drainer one.
If you could give me your thoughts and forgive my poor English, I'd appreciate!

I had the complete opposite to you, well in the first few weeks anyways. It would take like an hour to kill like 3% and I left my phone at 60% once, left it overnight without charge and only dropped 2% - This was the case a number of times

Fjesuino. I wiped my cache, and the battery time did improve a little. Try it out, it might work. But i think there is something wrong with your device android system and sd shouldn't be that high.

Thanks, i just got rid of fb for now. Will use stock browser. But i kinda like AOD, so i am keeping it on for a while. Anyways i wiped my cache and the battery has improved.
Its 40% now with 2 hours 50 min SOT including an hour of 4g browsing/downloading

S7 or s7 edge? Exonys or Snapdragon? Do you have the always on display turned on? How much screen on time are you getting?

S7 Exynos and back then I didn't really use AOD. It wouldn't be fair to show battery usage right now though as I'm using quite a heavy custom kernel.
As well as all the other tips you're getting above, I'd recommend flashing the Hydra ROM onto your phone as there are a lot of features to save battery. It ports to the Note 7 and you get features like reducing screen resolution, reduce background processes, it's even got its own RAM manager.
Personally, I don't see the battery as that much of an issue though and I do bash my phone a lot through the day as well.
Have you got a lot of apps installed? Do you have a SD?

If you're willing to void your warranty you can install a debloated touchwiz rom that will increase your battery life alot

The phones here in pakistan are mostly "smuggled" or imported. I have an imported one from canada g930w8, so it's without warranty.
But i dont want to root it, i have used many custom roms on previous android devices. i personally dont like third party ROMs that much. So i'll just debloat the current one.
Thanks for your suggestion ?
