Severe battery drain with a70. - Samsung Galaxy A70 Questions & Answers

So as the title says, I am noticing that my A70 battery is draining really fast. For example, in the last 15-20 mins I've been browsing Reddit and Facebook on 15-20% brightness, wifi on, mobile data off, power saving on, reduce animations on, nearly all 'Advanced features' off, no background apps running and my battery has gone from 81% to 74%. Is there anything I can do to maximise battery life? I really dont think I should be getting this much battery drain with the settings i have on.

Go into battery in the settings and press the battery usage button to see which apps are doing it.

[Q] Battery suddenly discharging on standby

Hi all
Yeeea I know you may think "WTF! another battery drain thread" But I've search the forum and there is nothing about that strange behaviour of my little big desire.
Usually at night when my phone is in plane mode and on standby, the battery drain is about 2ma (CurrentWidget).
But after a few hours of standby, the drain suddenly rises to 40ma. If i turn the phone on and off immediately, the drain returns to a normal 2ma.
Any Idea?
I'm using SetCPU with a "Screen OFF" profile. Could it be the cause of this?
Attached is a graphic of my battery. You can see that starting a 2 AM the phone starts to drain the battery and stops when I've switch it On and OFF a 8 AM

[Q] Possible battery life degradation with JB OTA update?

Thanks to everyone who got the URL out for the official JB OTA.
I have immediately noticed higher battery drain. Google Now is turned on. 1 hour and 40 minutes uptime from full charge, battery is at 67%. After checking battery stats, I see that Android System has consumed 64%, while the screen is at 14%. The screen power draw has always been the highest. In fact, before the update, the screen usage would probably read somewhere around 70%, and the overall battery remaining would be around 85- 90% (at approximately the same amount of usage as today).
I have read this was an issue with early unofficial builds. Is this an isolated issue? Or is this what we're stuck with?
First post. Thanks for reading.
I've had this issue too, but my situation was even worse. I was on airplane mode, Google Now wasn't turned on, and I lost 30% of battery just by using the screen for an 1 hour and a half, not even for games but just simple apps! (considering i was on airplane mode the whole day pretty much)
I am also losing about 30% per hour with screen on with simple usage
Check my thread in the General section, but Sprint enabled Connections Optimizer again with this update, I've found it to be the biggest battery drainer of all. Go in and disable it and see if your battery life is better.
Where is that setting?

Settings, more settings, mobile networks, connection optimizer.
Or, if you have Titanium Backup, you can just freeze the Sprint Optimizer app. That's what I did.

30 minutes SOT, what could be draining my battery?

I'm having battery issues. I am normally getting 2 hours SOT maximum, which reduced to 1h30 over time. I did a factory reset (still on stock android) and flashed ElementalX kernel to downclock the cpu/gpu, to hopefully save some juice, but it didn't change much. It looks like my phone is never going to sleep or doze and is depleting battery at a steady rate while not in use.
Here is a screenshot album: imgur.com/a/dezhr
Some **** won't let phone enter Doze, you can see Awake (screen off) line in Better Battery Stats. It means, that although screen is off, phone is still fully awake - probably an app syncing in background.
IMHO it's Google Play, not sure though. Try reflashing current ROM build and newer GApps, while keeping all data.
It looks like it was Facebook Messenger that was running constantly in the background.. Once I killed the app, the power stopped dropping. Also it seems that turning off the wifi helped a bit too (since there was no wifi available).

Doubts about battery A5 2017

Hi, I have doubts about the battery or need advices.
When I go to sleep at night and wake up in the morning (6 - 7 hours), the phone drains about 15 - 20%, is it normal?
When I go to sleep I put it in mid power saving, 80% brightness, wi fi and AoD activated, blue filter activated, auto brightness checkbox deactivated and in settings -> maintenance I erase RAM.
Even though, the battery lasts 36 hours or more.
Thanks in advance.
That's normal standby for most devices, though I don't really lose as much percentage overnight by just closing all apps before I go to bed and keeping the brightness low while leaving WiFi and Location Services on. I go to bed with 60% and wake up 7 hours later with around 50%, so maybe you're doing something wrong. But 15-20% overnight isn't really a big deal at all considering how fast this phone charges.; you get 20% back by charging for just 15 minutes. You'd really over ever notice a difference in standby time if you're coming from an iPhone which has the best standby time in the business, but this phone makes up for it just fine.

I see. In fact, last night it went from 60 to 51, so it depends on a lot of things.
Do you say I must change/add some other settings to improve the battery life?
Thanks a lot for your answer!

I knew for sure that my battery life increased exponentially when the phone started dozing apps I didn't frequently use. The phone hibernates apps after 3-7 days of not being used, but you can put them to sleep yourself in Device Maintenance.

I lost just 1-5 at the night I stop AoD,and wifi if you use Facebook app or social media apps will drain battery faster than when using browser it's better.:good:

Where exactly do I put apps to sleep? Or may I force them to stop? (don't know if it is said like that, I have it in Spanish).

Only 1-5% ? Amazing. Yeah, but if you deactivate wifi, you won't get any notifications of anything during the night (if you think about it, you won't answer any because you are sleeping). Maybe I'll try that.
I don't use Facebook too much, but the browser version is a bit slower and not comfortable IMO.
The principal app that drains my battery is the PvZ2, though.
It will disconects wifi even when you turn it on... I lose abou 2 to 3 % night, but I dont see point of having device on during night so now I power it ofd

Settings > Device Maintenance > Battery > Check the apps you don't frequently use and tap Save Power. If you choose to sleep Instagram, for example, you can still open it anytime later by just tapping the app, it'll just take an extra second to start which you won't even notice.

Instead of turning it off completely, you can also use the maximum power saving mode. Using that, I went to sleep with 97% and once I checked after waking up it was 96%.
I didn't measure the boot time of the device (not that I even care about it) but disabling the power saving mode might be a bit faster than turning the phone on.
Thanks all of you!
It is NOT normal for battery to drain 15-20% overnight.
Normal drain in that period would be 1-2% without AOD and 4-5% with AOD.
Battery wise A5 '17 have good one. I usually get about 7 hrs on SOT with medium ussage or 1.5 days ussage.

Default camera app battery drain

I recently bought this phone, I updated everything system, apps......the camera keeps running the background, even when I have closed the app.....
Problems does go away if I clear data of camera app...but I don't want to do this everytime.......I bought the same phone for my mum, and same thing is happening there too, on top of that in her phone chrome is consuming a lot of battery even when the phone is idle...... please help me out
Also I did try that restrict background activity but that option did nothing and the time on "while in background" kept on increasing
P.S location was off.
Never happened this problem to my European LG G7 Thinq (LMG710EM).
Anyway you have to turn off "background activity flag" to stop background activities of any app (do it for each app).
But consider also that the 7% of battery may be consumed just in that 11 minutes.
Shooting photo consumes a lot of battery...
After a week I have figured that you need to compromise on 2 features to get a good battery life ......1st obvious one was always on display, after disabling that, battery life increased a lot, but my idle battery drain was still 1-2 % per hour with wifi turned off.......2nd I disabled the double tap to wake (knock on) and hallelujah! Now on idle it barely drains 1-2% overnight.....
This is a great phone but lacks in the battery department...I mean, I don't mind disabling aod but double tap to wake is a great feature to have...too bad it drains the battery like hell
