Samsung s3 keeps dicharging after wiping cache

[Anuskha Mohan]

Hi all, My phone's battery was draining fast, so I wiped the cache after reading a few posts.

1. Turn off phone
2. Wait 5 secs.
3. Hold up volume button, home button, and power button until phone cuts on.
4. Let go of power button
5. When Screen comes up let go of all buttons
6. Use volume button to go down to wipe cache, use power button to select
7. Then press select reboot system

But now my phone keeps discharging when the battery levels reached 70 % and also when pugging it back on to charge it charges fom 70 % up.
Can you please help me fix this problem?

Thanks

Ok, so I replied to your post in the other thread, but will repeat here--do you mean that the phone shuts off when the battery reaches 70%?

Try letting the battery run down to about 20% (if you can), then plug it into a wall outlet and leave it there overnight, undisturbed. Check it again the next morning and see if the battery behaves more appropriately.

You could also try another battery and see if the same thing happens.

Hi Thanks for the reply. I already did that but still it didn't work, try to reach the 20 %. It keeps shutting down and coming back up. I did a factory reset after googling the whole day. Now it charges to the full 100 % but still keeps discharging when I unplug it from the wall outlet. That was the last thing I read of doing. I hoped that it would undo the wiping of the cache or something but it is still the same. I really can't do anything now. I think I would have to bring it to a repair shop. But I live in Suriname and they aren't that far with technology here and mobile phone fixing but the only hope I have is to replace the battery. Also I checked which app uses the most battery and my screen was almost on 80 % last time I checked. It was impossible. I removed all the widgets, put the power saving mode enabled and removed all apps that I didn't use. I am now leaving it on charge but when I am in the car it won't work obviously. Please let me know if you have any more suggestions. Thanks.

It would help if you could take a screenshot of your battery stats and post them. I would still leave it plugged in and charging overnight, even if it says it's 100%, then come back to it the next day (unless you've done that already).

I'm still not sure what you mean when you say it "keeps discharging when I unplug it from the wall outlet." It goes without saying that once you unplug the phone, the battery will start discharging--the question is, how quickly?

If you have removed a lot of your apps and aren't doing a whole lot with your phone, it isn't that surprising that the screen is reponsible for 80% of all power used, because the screen uses up the most power in proportion to everything else. So if your battery has dropped by 10%, and your battery stats says the screen is 80%, that means it's used up 80% x 10% = 8% of the battery. Remember that these are percentages, not absolutes.

I charged it overnight to 100 %. This morning I was trying to activate viber. It turned off, and keeps turning back on. That happend after 10 minutex max. After that I plugged it in to charge and the batterij level was at 36 %. So in a few minutes time my battery goes from 100 % to 36%. After restarting it quite a few times yesterday. The battery stats changed. The screen is no longer at 80 % but now it is 42%. I removed it from the charger to see how long it will hold. I tried keeping it running so that it can discharge on it's own but that didn't happen yet.

What I meant with: "keeps discharging when I unplug it from the wall outlet." is that when removing it from the outlet I use the phone for maybe 5 minutes and then it turns on. It kees doing that: turning on and off on it's own. But when I plug it in again on the charger it stays on. Only then I see that my battery as dropped from 100% to 36% procent.
So now I can only use my phone when plugged in.

This is the printscreen. Hope you can read it:
