[Q] Reboot problem+Battery - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I have a new SGS2 two weeks old. a few days ago my phone rebooted itself and reorganised all my apps, the next days it rebooted itself another 5-6 times. yesterday it just turned off and I needed to restart it. meanwhile I bought an additional original battery and an original samsung cradle charger on ebay
today my original battery was on 5% so I switched to the new one and put my old one in the cradle charger, when I finished the new battery and tried to use the old one that is suppose to be charged the phone is not responding with it and not charging it. My ROM is the original I havent changed anything.
Q1 anything about the rebooting problem, what can cause it? how to fix?
Q2 can the cradle charger ruine my battery?

[Q] Installed Bonsai ROM now GT10.1 won't charge!!!

My boss, a pro at this Android ROM thing, installed the Bonsai ROM on my GT10.1. We uninstalled because of the weird screen. I hadn't had my tab on a charger. Now, when I hook it up to the charger, it's still saying discharging. I'm down to 30% battery life. What happened and what do I do? My boss is gone, so I'm on my own.
Answered my own question
I went to a Sprint store and bought another GT10.1. I took the charger out of the new one and plugged it into the old one. It's charging now as we speak. I tried to use the old charger one last time and still nothing. I have no idea what's wrong with it. The old charger is going back to Sprint with the new GT10.1 so I can get my $500+ back.

[Q] Battery stuck at 0%, need battery replacement?

Suddenly my phone won't charge. Do I need a new battery?
Here's the details ...
Samsung Galaxy S2 (i9100)
CyanogenMod 10.1 Nightly (10.1-20121229-NIGHTLY-i9100).
I've had it for almost 2 years.
If I leave it plugged in, everything works fine. I can boot it up and use it normally. The lockscreen display and status bar indicate that it's charging, but it stays at 0%. If I unplug the charger, it shuts down right away.
It also seems warmer than it should be while plugged in, but I'm not certain that's part of the problem.
The results are the same whether I use the charger or a USB cable connected to the computer.
There's an immediate reaction when I plug it in or unplug it, so I don't think there's anything wrong with the charger or the port.
I've tried removing and re-inserting the battery with no change. I've also rebooted it several times... it shuts down when I unplug it anyway.
It just happened today, and I haven't installed or updated any software in the last several days. I have auto-updates in the Play store turned off. So it's not a software issue. The ROM was the last thing I updated and that was on the 30th.
I think the battery is really empty because I can't power it on at all if it's not plugged in. So, it's not just that the battery level indicator is wrong.
Hopefully, all I need is to replace the battery, but I was hoping someone here could confirm that or suggest what else might be wrong.
Thank you.
Check contact pins see if they are bent away or have crap on them. If not it sounds like the battery is dead, but I assume you already knew this.
I had already checked all connections and didn't find any damage or other problems. I bought a new battery today and that seems to have solved the problem.
Thank you.

I needed to write because this topic is on top on google results. I've lived the same today. A while ago i had a sudden battery decrease issue. There i was suggested to remove the battery and wait for a while. I tried this today. Removed the battery (simcard and memory card also... i just felt desperate). Waited for a while (i gues it was about half an hour). Plugged to charge. And my battery contiued charging from %61. I just showed wrong level.
This issue is happening to me too=/ but it happened to both my batteries in the space of two weeks

hi i have the same problem. i bought a new battery as mine was kaput. then a few days after that i needed a new charger port. now my phone wont turn on manually but when it is on charge it will randomly turn on for 10 seconds with 0% battery and then turn off. i tried doing the reboot with the power, home and vol up button but nothing happens. do i need another new battery?
I don't think it's the battery. I think it has something to do with these custom kernels and ROMs. I've been battling this problem for months with no results.
- I have a new battery, new cable, cleaned pins.
- Tried Lollipop, CM12 with kernel, one or two other kernels.
- Tried various KK ... CM11, Dominanx Kernel, some others too.
None work properly. I love all the updates but it's I just can't pin the problem down on my S2. I'd love to know what else I can do because I think I've exhausted all possibilities. Maybe JB is the only option? I dunno.
Help would be great on this.

Hi,
if you think the problem is custom ROMs then why don't you just go back to stock ROM and try?

I thought it might have been the pcb. I replaced that too but even that didn't completely revive the battery life. Went back and forth between JB and various customs mods to no avail. I ended up selling it for parts locally
Loved that S2 but it was time to walk away from it

I also had the same problem once. What I did was, went to recovery mode and charged for 1 hour and voila,it was charged till 21% only sadly. But by then,it has never rebooted like that!:angel:
hey ive also had a similar problem in which my j1 (Samsung Galaxy J1 (2016)) started to randomly shut down or restart around 2 months ago. Then, the battery would start jumping percentages like 100%, to 54%, then 33, back up to 84 in around 10 minutes. Then when I tried to charge it, it would stay at 0% and when Id unplug it, it would say 100% and shut down. Around late last month i ordered a replacement battery, it came in yesterday and worked fine up until a few hours ago. Now when i try to charge it it would stay at 0%.
Solution
1.Turn OFF Phone
2. Pull battery out
wait few sec
3. Connect charger
4. Put battery in
5. Turn Phone ON
Working for me. If not prob replace battery :fingers-crossed:

[Q] Boot loop when charging help!!

I have in my possession 2 galaxy s2 i777s one of which was thought to have a charging problem which is why we got the new one. Once i got the new s2 i tried to put the new battery in the old phone and it not only powered up but it also charged. i then put the old battery in the new phone and it wouldn't charge just like before, i keep getting a boot loop where the battery symbol would flash then go away periodically about 15 seconds apart i would guesstimate, this happens for both phones with the old battery, but both phone charge the new battery. I came to the conclusion that the battery may be the problem and set out and bought a new battery and gave the old phone to my mother thinking problem solved, only to discover the problem still existed, replacement battery wont charge same boot loop. Thinking lightening did strike twice and the battery was faulty i returned it and got another one same problem, boot loop when charging or connecting the usb to the PC. I tried the battery in my new phone same problem, i looked at the specifications on the battery to see if they were the same and yes they were exactly the same:
1650 mAh,
3.7 li-ion
6.11wh
made in china
i have MULTIPLE usb cable that are compatible and MULTIPLE chargers that are compatible and i have tried them ALL. a person suggested i take the battery out plug in the phone then place the battery in while plugged in, didnt work. i tried cleaning the contacts on the battery and the phone itself and nothing, the new phone is rooted but the old one however was bricked in an attempt to root then factory reset, i dont know if this plays a part in it, but remember the battery from the new phone charges in both phones and the the replacements dont charge in any. i had tested the old battery in the new phone before it was rooted or had any apps or anything on it and it did the same thing, boot loop.
any suggestions?
im new to the whole do it yourself root and rom thing so please keep that in mind when tossing certain phrases around.
Edit:
ok after searching some more i eventually found out the reason for this was because the battery I bought was incompatible, though the guys at the store said the battery would work for the i777 which it did, it turns out there is something different about the standard of which the battery was built.

Welcome to the forum. & thanks for using the search option There's a lot of great people in these I777 forums & do great work. Enjoy your new flashing addiction.

Based on everything you've said, I would strongly suspect bad (or incorrect) batteries. You must have I777 replacement batteries. Ones made for the GT-I9100 will likely not work. I suspect that is your problem.

Random reboot and phone's death for some days

Hi everyone! I've a problem that's bothering me since i've bought this phone. Let's start from the first day when my beautiful gs2 arrived and there's no way it would turn on, i tried charge the battery but it didn't work too, it displayed the grey battery logo and then reboot in a loop. Then magically after some hours it started working. After a few months the phone started rebooting or powering off by itself and after a few more weeks it wouldn't turn on or charge like the first day and like that it returned to life after few days. I took it to a samsung point and they changed the usb connector.
It all worked fine for a few months and then here we were again and the phone died and turn to life after few days and also this time they changed the usb connector.
Now it's begun rebooting again and i think it won't turn on few weeks from now.
I've noticed that when the phone reboot there's a vertical drop in the battery charge, almost to zero, only to recharges by itself instantaneously after rebooting. Few days ago the phone didn't reboot but the battery charge went instantaneously from 60% to 10% and then started slowly charging by itself till almost 25%.
What do you think about it? I'm starting to think the problem is the battery chip that control the charge, is it possible? It's integrated in the battery right? so if i change it the gs2 would be ok?
i would personally try another battery.
if that doesnt work, it might be the u503 chip on the phone.
i recently had an issue with that chip after slight water damage (http://forum.xda-developers.com/showthread.php?t=2462207) and noticed the same issue with the battery level, and it not turning on sometimes. tried with 3 different batteries and had the same problem.
got rid of the u503 chip, and its working fine now.
The problem is i don't have another battery. I tried the battery of a friend and it came back to life but there's no way to tell if it did the trick because it's random. The other times one second it was dead and the next one it was working again even without changing anything.
In my case when the phone reboot it doesn't get hotter so i think it's different from yours. More over is still under warranty so it's better not to touch it yet

Bootloop when swapping out batteries/battery level bug?

I have an LG G5 SE (H840) and I've carrying 2 spare batteries everywhere I go for the last 6 months (since I got them) because not being tethered to a power bank is awesome but this phone's battery life is disgusting.
The batteries and the charging cradle are all genuine LG products, one is my original H840 battery (manufactured in 2016) and the other two and the cradle were given to me by a friend of mine whose H850 was replaced with a G6 under warranty for an unrelated issue (SIM card not recognized) so he had no use for them anymore.
Yesterday I hit 20% so, as usual, I swapped out the battery with a charged one and, when it booted, it showed I had 2% and then shut down. Fair enough, I thought, I must've picked up the one I didn't charge. No worries, I'll pop the previous one back in and charge it up. When I put the previous one back in, it shows at 2% as well and does the exact same thing.
I let it charge from a wall socket and left it there for around 30 minutes only to find it bootlooping when I come back. It won't boot if it's plugged in. I disconnect it, it boots and it shows 4%, so I plug it in and it charges to 100% without any issues. Meanwhile, I put the second battery (the first one that showed 2%) in the official charging dock and the three LEDs turn on, meaning it's fully charged.
Since yesterday I've tried swapping out the battery a couple of times and the results haven't been different. Bootloop and if it boots it shows at 2% even if I just removed the battery from the cradle fully charged.
If I reboot the phone without removing the battery it has no problems.
Has anyone had this problem? My warranty expired last year because I got the phone in late 2016 as a replacement for a G Flex 2 bought in mid 2015 so the 2 years expired in mid 2017. Plus my bootloader is unlocked so even if I still had a warranty it wouldn't be valid. I'm running stock ROM and kernel, because there are no ROMs for the SE.
I really don't know what to do, this phone was perfect for my needs and of the current phones on the market, the ones that suit me are either too expensive or lacking awesome features such as USB Type C (looking at you, Xiaomi).
