Samsung Galaxy S II :: Battery Level Drop From 40% To 9% After Reboot
Jun 9, 2012
I just registered on the forum because i have a weird problem. My GSII first shows 'no network service' and it won't change unless i do a reboot. after the reboot my battery went from 40% to 9% It happened 3-4 times in the last 5 days. I already did the latest ics update via kies. the phone is not rooted. I did the hard restart. nothing helped. Here is the picture from the last drop [URL]
I recently got a brand new Galaxy S II with a new contract and have been using with a lot of joy. However, recently a problem occurred with the battery in a sense that it sometimes suddenly goes from 30-ish % to 0 instantly, therefore causing my phone to shut down with no warning. Also, after this happened, I cannot just plug in the phone to the charger, because for some reason it does not charge. I have to remove the battery and then put it back in again before I can charge it. This has been happening almost daily and I don't know what the cause is. The phone is not rooted or tampered with in any way.
I notice in some screen shots that people post that they have a Battery Level Indicator. I have seen these on the graphs from settings/about phone/battery usage.I don't have this indicator. The only time I see a battery level is when charging.
I posted about a problem with my battery losing up to 30% battery on reboot but got no answers so am hoping somebody will test their phone for meWhen my battery drops to just below 50%, if I reboot by pressing and holding the power button for about 8 seconds, on reboot, my battery has dropped to as little as 13%, even if there was 48% left prior to rebooting.I originally thought this was happening after tethering but it has turned out, it does it regardless of how much or how little I use the phone and even without tetheringI am on stock 2.3.4 XEU, manufacture unlocked and wondered if some kind soul would be kind enought to see if they can replicate the problem.It needs to be the 9100, complete stock and not rooted really as I am trying to determine whether it's a hardware issue or software issue.
Yesterday I let my battery drop to below 5% for the first time, just to see how long it would take. I noticed that as soon as the phone hit 5% it dropped the screen brightness down so dark I could barely see that it was on. When I opened the notification bar, the brightness control was gone. Plugging in the phone immediately brought it back to a usable brightness and the control returned. Is there a way to disable this?
I've come from an iPhone 3GS where in order to scroll within drop down lists in the browser, you use two fingers to scroll up and down, then 1 finger to make your selection. This doesn't seem to work on the Galaxy S2. Is there another multitouch way to interact with drop down lists?or example, a site requested my date of birth and the drop down list for year started at 1902 and showed the next five years. The only way I could work out how to get to my year of birth was to select the highest number showing which then closed the list, reselect the list and select the highest number showing which then closed the list, reselect the list and select the highest number showing which then closed the list, reselect the list and select the highest number showing which then closed the list and so on and so forth until I got to my year of birth.
On the Galaxy S2 even though the ringtone volume is set to max, initially it starts off quietly and gradually increases in volume. Is there any way of changing this to ring at a constant level instead of starting quietly and gradually getting louder - the number of calls I've missed because of it.
I generally don't have trouble getting through a work day with my S6, but I do wonder whether the Android utilization is high. During a typical day (1 - 2 hours SOT, 14-15 hours off charger), I'm burning about 60%-70% of total battery, 30% of which is Android System (~22%) and Android Kernel (~8%). Google Play and other apps are all typically < 5%. Is this normal, or does this indicate that a factory reset might be a good idea? On previous phones I don't recall core Android being this high (usually <10%).
My S2 has behaving a bit strangely now for a while, but after updating it to ICS it seems to have gotten worse!
The settings I use daily are (amongst other ones):-
- WIFI off - bluetooth on - ringer vibrate - brightness 25%
Before ICS, when I switched the phone off and then on again, it would change the settings to the following:-
- WIFI on - bluetooth off - brightness 50%
After ICS update it now also resets the ringer to loud, not vibrate.
It seems to make the changes shortly after it boots. For example, I switch it on, put my pin in and the bluetooth is on, wifi off, ringer vibrate (as it was when it went off). However, shortly after my home screens have loaded with their icons, the BT, WIFI, brightness and ringer all change, almost as if it's loading some default settings.
I just got a new 32 gig micro sd card. I tried to use media monkey to sync my music to it, it did a few then stopped. Phone needs to be rebooted as mtp application seems to lock it up.I then tried the same via the Kies program and the same happened, did a few more this time, maybe 5 albums then just 4 songs then stops and phone has hung again.
Since upgrading to ICS, connecting to my car stereo via bluetooth causes the phone to reboot itself. At first i thought it was just whilst streaming music was causing it as i could play 3 or 4 tracks before the phone just shuts down and reboots.
However, today i just had it connected for the phone function only and the same thing happened after 5 - 6 minutes.
The stereo is a Sony MEX-BT3900U which worked perfectly prior to the upgrade.
Carried out the upgrade using Odin3 v1.85 and flashed following one of the guides on the forum. Everthing else appears to be working fine and i quite like the new look etc, but if i can't find a solution to the phone rebooting itself think i will go back to GB.
If i set my phone to airplane mode (which i usually do at night) the next morning i'll find it with near to no battery and just hanged on the samsung logo. I've tried to leave it out of airplane mode a whole night and it did not crash. Now just today, to see it happen, i set it to airplane mode, within an hour/hour and a half i tried to pick it up and wasnt responding to any button and suddenly shows the samsung logo.
So i'm pretty sure now that the behavior is linked to Airplane mode. I've cleared cache etc. I'm just not sure where to start. There must be something that just crashes the phone when in airplane mode. Going for factory reset is out of the question for now (well idealy). ps : it was fine under KK
Where to start/what to look for ? I'm in the meantime downloading the Android SDK, after that I'll put the usb debugging on and have an adb logcat running and force a crash again.
Within a minute or so after my phones removed from the charger it drops to 95%. After that the battery life is normal. I recently updated to 4.3 and it might coincide with this issue but I can't be sure.
Every time my phone reaches around 10% it instantly drops to 3 or 4% then instantly after that to 1%... So basically I have to charge my phone before it gets to 10%. Not that big of a deal, but it is annoying not being able to do anything with it when it's at low battery and I'm away from a charger.
I'm trying to charge my phone before it gets that low from now on so I won't shorten my battery's lifespan so I can't comment on if the issue persist, but I will say that the calibration has made the battery to act less weird as far as dropping fast in certain areas but not others.
The problem is that my battery indicator stays full all the time. Battery life is OK (2-3 days) but is very annoying cause I don't know the battery level. It pass from max level directly to 1line and shortly the phone switch off.I tried 3 kind of firmwares (including last one 410.21.010), charging phone in different ways, different chargers, hard reset etc. and nothing.The phone is new (2 weeks of use) but no warranty.Any solution?
So, I opted to do a restore on the new iPhone 4 from a 3G running iOS4 image. Everything seems to have restored just fine but I've noticed that the battery level percentage isn't being reported on the top of the screen. I've crawled through the settings and can't find anything on changing this.Was wondering if anyone else had run into this or if I'm going to need to bite the bullet and build the phone up from scratch. To be honest this shouldn't be necessary, but could be my only option.
BTW, my reason for doing the restore is simply a matter of data. I have several apps that contain 2 or more years of information. Most have a "save/restore" feature but several don't. Even those that do have their own unique way of saving which will add time to building the new phone.
My battery level was around the 50% mark, and then I went to lok at my gallery and whilst I was viewing pics it dropped straight away to 1% and told me to charge my phone..........So I plug in the charger and it goes straight back to 47%. It has done this twice, why?
I purchased a second hand nexus 5 to find out that the battery indicator is always showing 42% and never updates, regardless of the actual battery charge level. I tried replacing the battery with the one from my brother`s nexus 5, then replaced the usb port board. Also tried:
- rooting - installing twrp 188.8.131.52 - elemenalX 6.0 kernel - Android 6.0.1 - Cache and dalvik wipe - Use the battery until phone shuts down
Although the indicator jumped to 83% and to 54% after some actions which I dont remember. Maybe after cache wipe, not sure.
I just got this used blackberry bold 9780. At about battery level 30-50%, the battery level will plunge to 1% within minutes. And it will stay at 1% for the rest of the day. Today, the battery indicator was working fine till the battery was about 30%, then the phone just died.
My observation is that REBOOT issue some how related to battery level reader s/w or something. because as soon as battery level goes below 80%(approx), device start rebooting and after some reboots it shows battery level in "red'.
Remove battery put back and 80% cases reboot cycle stops and battery level is normal. However it remains for some time only. try to make/recv call and it starts rebooting again.
The battery level often drops while charging. For example, it was 30% when I began to charge it. It reached 80% 20 hours later. I continue to charge it. 8 more hours later it became 0%. A few days ago I started at 15%, went up to 68%, then down to 11% in 30 hours of continuous charging. What is the cause of it? I just deleted many apps hoping to save the battery.
I used HTC 4g Amaze before and loved it. Then I had iPhone 6 for a couple of months, Samsung Note 4 another couple of months. I waited to get M9 believing it to be great due to my past experience with HTC. However, the problems with this new M9 are insurmountable.
my battery level drops suddenly from 15% to 1%.but when i connect to the charger it starts from 15%.did everything i can.reinstalled firmware 3 time.2 time with SEUS and one with the pc companion.went to the SE shop and changed the battery and got a new battery too, coz i had warranty. but the problem is still there since 5 months back?
I am facing a strange issue my Xperia neo is powering off the phone when battery level falls below 30%. First I thought its my oversight seeing the battery level but today again as I was typing a msg, the phone gave me warning battery level 1% and just got off. When I connected it to charnger and turned it on the battery level was indicating 28% power left. Can it be because of any application? I am using Juice defender as well.
Not too sure why but recently my battery life on my iPhone 5 has been awful! Firstly, I noticed the battery slowly starting to get worse at first, where I would barely make it through an evening and just about keep my phone alive. I then bought a charging case to use on nights out, which soon enough seemed to not be enough to keep the phone on.┬
Now, on a daily basis my phone switches off and I have to charge it throughout the day, I turns off sometimes just suddenly at 40% battery, other times at 20% and others it quickly jumps down to 1% and turns off shortly after. Earlier today I left my office with 86% battery. Went outside to make a phone call for maximum 15 minutes and my phone had quicky reduced to 10% low battery by the end of the conversation and 1% between my walk of 3 mins to then turn off before I was back in my seat.┬
I have experienced bad battery life on my previous Iphone but nothing like this. I did, however take it into Apple and where they backed up the phone and replaced it with a brand new one, however this iPhone is not still in my warranty (not entirely sure if the previous one was either to be honest).┬
I have done all of the recent updates, I close any existing apps and am not constantly on my phone anyway.
