Bad battery drain on A70 after update

MJM01 — Wed, 06 Apr 2022 08:45:12 GMT

I recently had updates (not sure exactly what, but now on Android 11, One UI 3.1 ) and the battery was draining as I watched!

I deleted the cache partition which helped, but it's still only lasting about 50% of the time it did before the upgrade.

Anyone else have this, or any ideas?

Thanks.

Both of our A70s have ridiculously bad battery life after the recent update. I unplug in the morning, it sits in my pocket all day, no calls, no usage, and by the end of the day I've got 40%. If I actually use it for something I can watch the % drop. It has dropped 2% while replying to the message! It's always physically warm as well so something is definitely constantly drawing power.

Same with my A70

It drains in four hours instead of two days. If I check the battery consumption - the use is equally spread across the top 3-5 most used apps, so no sinner among them.

I have serious problems with the last update. Apps are consuming 40% battery capacity in an hour. consumed about 3% in one hour of use.apirs the battery lasted all day. Now it doesn't even last four hours. With the screen on it lasts about an hour of use

I'm facing the same issue in my A70. I reset my phone but no improvement. The problem occurs since the last update. March 2022 security patch update. It's totally annoying 😩

Yeah man, the same problem with my A70, but now I am sure it's not the battery issue, it's a new update causing the problem ,i sent an email to Samsung,but they reply to me with typical massage that' i should use power saving mode,low the brightness ,turn wifi off when not in use bla bla bla.

Don't know what to do now

@Hassan100

I've also complain to Samsung. It's there formality to say trun off wifi,,low brightness bla bla bla...

I've tried everything. Reset my phone, wipe catch partition from recovery mood, everything ....

But At the end of the day.. I'm still facing the same problem. We should wait until Samsung release another update to fix this problem. I'm hopeful that they will release an update solving this issue.

Update:

I installed a battery monitor and let it run for a few days. Had a look last night and Pedometer was using 27%. I stopped it and only lost 18% overnight! So not sure what's going on, but I have my battery life back.

How do we turn off the Pedometer? Did you just turn off samsung health?

No, I had a 3rd party pedometer app. Try turning off Health - though better off installing a battery monitor (I have GSam Battery Monitor) to see what is taking the power.

I have same issue. My a70 battery drain much more faster after last update. I have got a new battery, but is still worse than it was before the update. What i have to do? Buy new samsung model? If it will not fix it soon, i will never buy samsung phone anymore.

Just a confirmation that I ended up using Odin to refresh the A70s back to the security update before the last one (I think it was September) and they are both back to all day battery life again. It's 100% that stupid March security update that made the phones unusable.

Hi, I would like to do that as Samsung is not giving us any solution. Could you explain or share a link where the process os downgrading to a previous security patch is shown?

I have googled this because I have exactly the same problem. Brilliant battery life the day before the update and literally can see it dropping from the day after the update. I thought at first it was just my phone but couldn't see how it could change so drastically overnight

Re: Bad battery drain on A70 after update

Either of these links should walk you through the process. I got my replacement September 2021 stock firmware from HERE, make sure you get the right file for your country/phone.

The only difference was that when the guides say to hold down the Volume up + Bixby + home buttons you just hold down the Volume Up + Volume Down.

Don't forget to back up your phone first. Hope that helps!
