Sudden battery loss after reboot

[adlebo]

After rebooting my phone I had a huge sudden battery loss. Before I rebooted my battery it showed 70 and after the reboot it was at 08. Did anyone ever have this problem? What can it be?

It has never happened to me on any of my phones, even since the PalmOS days and the two most current Samsung Androids I have.

Did you try rebooting again to see what it reads? It might have been a weird glitch?

Mine does this about 50% of the time if I reboot with vol down+camera+ power. I've even had one instance of it have a 40% battery increase after one of those restarts. I'm runnin rooted dk28 with truly epic.

I have a problem where on full charge it says I am at 95% battery life. I want to get to 100%. Is that possible?

Try this.... Unplug it and then plug it back in and wait another 15 minutes or so. Sometimes you may have to repeat but that usually works for me. I don't think it really gives your battery any longer life though.

The soft reboot every now and then does that battery decrease, but it is not really a battery drop. You may have to do a full restart or battery pull to get your true battery level back. Don't know what causes it. As for the 95-97% battery, I've heard that this is because of the battery circuitry that shuts itself off from charging so it doesn't get too hot which can happen if you over charge. This is normal, and if you can get it upto 100%, it won't stay there for longer than a few seconds. I've been able to get mine to 100% for a little longer using a wall charger with the battery out of the phone...but I don't really know if that is hurting the battery.

i was able to get higher but realize there is no point to it. but thanks to both of you anways

I use a separate charger for the battery so I get 100 percent. It stays at 100 percent for a while that way and does give me alittle longer battery life. Not a lot but 5% is still more

if I'm under 50% and reboot it will usualy drop to below 10% . Crazy anoying

I had the same problem last night for the first time

Thats how I get 100% also via external charger on all 4 of my Samsung batterries, and its the only way I can get 100%, it will also stay at 100% for about 15 to 20min - I used to get 100% on the built-in phone charger, but would stay at 100% for 5min or so.

I've had this happen to me also, but as soon as i plug it in, it jumps back up to where it was b4.

so did I! but since I have extra batteries I just swapped them out to be safe. Can't go out on a friday night with a dead phone!

I've been having an issue where once I get down to around 30-40% battery it will suddenly drop to about 5-10% almost instantly when I make a call or use the screen for a minute or two.

I thought it was because I'm using cheap hong kong batteries. Can't use my original factory battery to test it because I accidentally sent it through the washer... Doesn't happen all the time anyways.

Did you reboot from cwm after flashing something? I have noticed, and actually expect now to loose at least 15% when I flash something.

I got the same problem too on my samsung j1 ace... i got 50% of battery after rebooting i got 3%

Let me tell you what happens to my Samsung Gran Duos: If it has 75% it might drop to 40 after reboot, but when it hits 1% instead of turning off it remains on for a long time, which makes me believe that just the information is incorrect and that the battery level itself does not drop after reboot. So I just stopped worrying about it.

I had the same problem with the same phone, but i never tried to keep it for longer like you did. Lots of ppl said it was from the batteries and i tried buying new ones, but they were not able to charge after the 5th mounth. I thought it was from the quality of the first battery so i bought another one and i keept on repeating, but i stopped on the 4th one bcs i found out that it was a waste of money. I tried back the original battery, but after time it expanded and this caused a lot of issues such as an oily spot on my screen and your problem started to show much often than b4

And i ended with a new phone after 5 years of using my old Samsung Galaxy Grand
