My battery life has become quite suckish lately!

[Leslie Hatcher]

What the heck? I leave my phone off the charger one night and it loses battery like crazy! It was on 71% when I went to bed at 1030. Get up at 645 this morning and battery is down to 34%? I attached a screenshot. This stinks!

its usual with android but your problem is really aww
1.improve your charging habits
like never charge for 100% totally charge like for 20 mins and use again20mins after uses
2.try apps like greenify and doze
3.if problems really get worser then time for consulting to your provider or change battery with new if possible.

Go to settings-storage and clear your Apps Cached Data, then turn off your phone and Enter to recovery Mode by pressing, Home-VolumeUp-Power button until you see some texts on screen or the Android Robot, once in Recovery Mode do a Wipe Cache Partition, just browse using the volume buttons and press power for enter.

Most of the times this fixes unknown OS issues that causes all kind of problems on the phone, including battery issues.

And it looks like you have 4 weather apps polling for weather updates and location. Any way to condense your weather apps to maybe 1?

Mine has been pretty bad too. The main culprit for me is the Android System. Used to get 4.5 hours SOT consistently now down to 2 at most. Not sure why.

Cell standby looks awful. Are you in a bad reception area? That'll kill your battery.

I was on WiFi, but have plenty of signal. I have cleared the cache and partition and restarted the phone. Next step will be a reset. Last resort? Back to my iPhone that has a killer battery.

Lol! Yeah, I'll give you the link to Doze on Google Play and a link to buy a spare battery for your S7 edge! As to point #1, whaaaa?

Why do you have four weather apps? That's a good idea to kill battery.

No its not usual with Android. I lose less than 5% overnight.

Something very odd there. I get battery life like this. Exynos processor:

Here are some things I did.

Cleared system and app cache which you already did.

Turn off always on display

Turned off Google location history.

Doing that got me from 7 to 8.5 sot.

 

[Jtshurtleff]

Got mine back to where I want it after wiping cache and app cache. Hope to be back to 5 hours SOT tomorrow.

 

[IAmSixNine]

yeah cell standby is way to high.
Ive found that my device has better battery life with WiFi OFF.
Why i have no clue..

My phone developed a similar issue. CellStandby suddenly topped the battery usage list and the phone would average 25% battery usage while I slept.

I don't accept that a weak signal is to blame because I still have my Nexus 4,, it's nearly 4 years old, it's on the same deal with the same carrier and it doesn't suffer from this alleged 'weak signal'. I had to charge the S7 Edge three times in the time the Nexus went from 100% to 1%. The Nexus 4 battery has never been changed, it's a near 4 year old battery. It has 2100 mAh battery up against the S7 Edge with 3600 mAh.

I was advised by Samsung support to clear the cache as described above but that made no difference then they advised running the phone for 24 hours in safe mode but that made no difference too.

The phone is a much newer model than the Nexus 4 and you'd expect better performance across the board. Anyway, it's been sent in for an engineer to have a look.

LOL you may not accept that its a signal issues but comparing your Nexus 4 to the S7 edge signal is a really bad comparison. I dont recall you mentioning what carrier your on BUT TMO for example you dont have the same bands in both phones. So your S7 Edge might be on Band 12 which may be giving you problems and your trusty nexus 4 is staying on band 4 or 2 or which ever it did have. Now if you have 2 of the same phones and one is not giving you the issues and both are on the same carrier then you can not accept it. Till then you must accept it. lol Not only that but your screen capture does indicate that after 12+ hours your cell stand by time was huge.
On second thought, i dont accept your picture of cell stand by being so high. It must be doctored.

 

[mia_xoxo]

Same! I pull my phone off the charger around 6-7am and by 12pm I'm at 30% it's terrible. Not sure what could be causing the drain.

I'm also going to guess that you don't have nearly as many apps running in the background on your 4 year old phone.

I haven't doctored anything about that screen capture and we've seen what Samsung's quality control is like recently that even after a recall and some major adjustments, one of their phones is so bad they're having to cancel it altogether and issue refunds, so your can keep your snide remarks to yourself.

 

[Doc Marten]

But in the list the top user of the battery was cell standby and no apps were using significant battery. Therefore your guess isn't really a meaningful one.

LOL...so you think that doesn't mean you had apps running in the background? Think again. So I'm not sure what you're talking about.

But even more so, it sounds like a signal/WiFi issue.
