When the phone dies due to battery drain it causes data loss

Hi,
Whenever my phone dies due to battery drain I lose contact information, texts and application settings and other settings.
It has been happening off late. It was fine some months back.
I am on 2.3.5 and my phone is still under warranty. Is there anything I can do to prevent this?

Never heard of anything like that before. Anyway try flashing a new firmware 2.3.6. GB and give it a shot.. If the issue still persists, a service Centre is the best option..

Try simple things to minimise battery drain like alway turn off wifi, 2g, 3g. Use it only when its required. Other time turn it off. Flash xxkpq firmware & use UC kernel. Also tweaks & governers will help u alot. Also sync of mail do it manually. Auto sync always take ur battery like hell.

Dude the problem here is the loss of data after (maybe) reboot.. Battery drain is not the issue..
So the best way to check if it is a hardware issue or not is to flash a new firmware.. No mods required...
And she's obviously new here so let's keep it simple.. Flash guides and the links to download the required roms in the stickies section..

I read recently that turning off journaling can cause data corruption/loss. are you running stock, or customized? some customized roms turn off journaling for better performance...
in addition, for better apparent performance, some roms also increase read ahead/write ahead or something like that. if you were doing something when your phone dies (and is unable to shutdown properly because you pushed it to the max), it can die in the middle of reading or writing, and especially in the case of writing, likely will cause data corruption/loss.
so, once again, let us know if you're running stock or custom, and why you insist on killing the battery while using the phone instead of shutting it of at 1% or 2% to prevent this from happening anymore

Mam.,
It is advisable not to let the battery die.use apps such as juice defender, if ur problem persists go to the service center

I will try this today. Do you think I should try a factory reset as well and see if that helps?

But I can't keep preventing my battery to run out. Why should a battery drain erase data? Obviously the problem is worse than just battery draining.

I don't wait for the battery to drain. When my battery is a little less than half at night, I wake up to find my phone turned off with the battery run out. And all of the mentioned data erased.
I have stock rom. Should I just update my fw to 2.3.6 and see?

A likely scenario here, which also occurred to me was that when kept overnight, the phone restarts automatically and gets into a boot loop (stuck at the samsung logo, and reboots over and over) thus draining the battery of whatever charge is left. And then once you switch it back on all personal data is erased, including settings, except installed apps.
What firmware are you using? This is surprisingly a very common issue nowadays, happens to many on GB, I have not heard of this happening on froyo as yet, but you never know! I myself have given in my handset for a motherboard replacement due to this!
So the issue might not be battery drain, just keep it unattended for a while and you will see its behavior! (Or wake up in the middle of the night! )

Well till now all those facing the problem couldn't solve it even with multiple wipes/firmware installs, so best bet is the service center, insist on a MB replacement on the 2nd visit, because the 1st time they will just do a firmware flash.
Make sure you are on Indian firmware DDKP1/KP2 with no trace of root including superuser and CWM.

that's different
your issue is not a loss of data due to battery dying, it's due to a hardware malfunction. take it to sammy!

same problem with me.. i heard its from the motherboard and internal memory.. i was using xxkpm then... At night i turn on wifi to update my apps on market.. its good, everything was updated, but tomorrow morning when i woke up i found my phone dead, so i charge it and when i open it, i was surprise to see that its asking me to pick a language again.. and yeah, all my contacts are gone, the messages, and the settings.. I thought its because of some apps that is update.. so i uninstall all my apps and then factory reset. but still same things happen everytime my phone is idle for awhile.. i also tried to flash xxkpq but same thing happens.. i still have warranty but is it ok if i go to samsung center with XXKPQ? or should i flash again to a lower version like 2.2.1??

[L 5.0.1 ]Enormous battery problem

Im experiencing a huge problem with battery...
First the battery drain is too big to be real 100 to 0 for like an hour of browsing...
What is more is that when the battery gets like 30% the phone sometimes just shuts down like and acts like the battery is fully drained and the only way to turn it back on is to connect it to a charger first and when i turn it on its on 0% battery.
I'm running all stock, no rom, not even unlocked, I sideloaded both 5.0.0 and 5.0.1 updates.
Here is some screenshots, could it be a bad 5.0.1 update?

Have you done a factory reset yet?
What happens if you charge it when its off?

Welcome to the club

It charges normaly, just like I have let the battery die to 0%. Other then that it charges preeeetty fast ... Too much if im not overreacting
Haven't done factory reset....thats the reason for not flashing it, didnt want to lose data..

Well, it could be hardware but best thing to do is rule out.software so best bet would be to factory reset after backing up your data. Maybe even flash back to stock.

The reason behind not flashing already etc etc is that i dont wanna lose my warranty. That leaves me with factory reset and nothing else for solving it? Should I just copy all my storage to PC or should I use some application for the backup?

You'd need to reset the flag then afterwards. Its all covered in the flashing stock guide in general > sticky roll-up. Not saying you should do it, just letting you know. Though after you factory reset i would recommend you probably just contact the company and let them fix it.

I guess I will have to unlock, root and flash my Nexus to see if this will help.
Can u advise me with a stable and low battery drain ROM and Kernel eventually ? I'll need to seach a full guide on unlocking rooting flashing I guess

If it's new, go and get a replacement. If it's not you may change your battery. It does not look like a wakelock or another issue. It looks like a hardware issue much more.

Actually, I do have the same problem as OP. I'm thinking of going back to 4.4.4.

Facebook app is draining a lot, Disable Service and disable the fitness services within Google Play Service, and disable unneeded syncs.
Sent from my Nexus 5 using XDA Free mobile app

I had the same problem with mine, I used the nexus root toolkit to get back to 4.4.4 and it fixed my battery issue completely, I'm now at 23hours with 36 percent left. On 5.0 it lasted about 8 hours if I didn't use it, good luck.

Flashed Cyanogenmod 11 latest for hammerhead, problem persist... I'll do some more testing and If I cant get it right I guess I will send it back for repair after reseting the flag...
If anybody has any ideas or same problem, share info

I'm having the exact same problem...
I updated to 5.0 when the OTA was sent out OTA but then sideloaded 5.0.1 two weeks ago.
Since then I've been experiencing the same shut downs where the phone thinks the battery is dead. If I leave the phone off for a minute or two, restart it and then leave it for a few hours, the battery level slowly increases back up to what it actually is.
I'm guessing it's a software issue but I'm losing patience waiting for 5.1 to cure it.
I'm now thinking of downgrading back to 4.4.4 till 5.2 comes out. Very frustrating!

What voltage is actually at when this happens? You guys should track voltagr at full charge, and empty when this happens.

The new baseband / modem firmware from lollipop caused massive drains for me. You may want to flash 4.4 baseband.

I haven't had any battery issues on Lollipop, in fact it has been better for me than Kit Kat. But the first thing I did after the upgrade was to backup my phone, copy the backup to my OTG stick (the computer would also work) then factory reset. One this was done and I setup my phone I copied the backup back to my phone and restored. After about 5 days to allow the phone to settle, I got 36 hours on a charge with 6+ hours of SOT.

See here - Firmware Official
I'm surprised you said you don't see any improvement in performance because I certainly did.. I'm even getting between 8 and 11 hours of SOT whereas before I was only getting around 4 to 6 so it literally doubled it.. It may also be because I've got a lot of things disabled and I did an entire clean installation of the new firmware because I factory reset right after flashing it and then disabled/ removed a lot of junk and so far it's working better than any of the other ones I've tried!!

I happened to factory reset just before I knew of any new update. Now that I have the update, should I do it again?

Yes, it is always best to reset after a update.

Have used the update for a couple days now without doing a reset and so far it is better than the last update with a reset with performance and battery life, very impressive. I didn't disable any services/packages, only the disabling of apps which the UI allows by dragging/dropping from the app drawer since my last reset. This helps immensely with the ability to do dirty updates and staying at near peak performance, just an FYI.
May do a full reset this weekend just to be able to start fresh and test, but may not if the current state of my phone stays the same.

When you guys reset, do you use the most recent copy or install from scratch? I see 3 choices, last 3 days, last 30 days, or install a fresh copy. I used the last 3 days choice.
All it does is install your apps so you don't have to pick them out once at a time.
Thanks

You know, I think its possible to go way overboard on the whole reset after every update thing. Remember that now that Samsung is pushing the monthly Android security patches on a more or less consistent basis, you are going to be getting an update almost every month. Do you really want to be resetting that often? Up to you but that's not for me. I did do a reset when it went from 5.x to 6.x but I don't reset just for the monthly updates. I haven't had any problems either. I may do a "just because" reset after six months or so, but I think if you are doing this for every single update its going to get old really fast.

If you know what you're doing, and which backup apps to use, guess what? It takes less than 5 minutes to restore all of your stuff after a full reset..

Can you elaborate for the people that it takes longer than 5-10 minutes to re-setup? Are you using a backup program (which one) to use keep your data settings? I know some programs will allow you to backup the data/settings so you don't have to start from scratch but not all allow you to do this. I'm just throwing this out there. I don't need it because I like to reset mine back up... Makes it feel as I have a new phone.

anyone have the Tar Ball for this update? I have a Note 5 in an endless bootloop and SamMobile takes more than two hours to down load. The bootloop is so bad that you cannot get into recovery, the hardware power down does not allow factory reset or power off and the only one that seems to work is to odin the clean software.
Thanks.

Help: Android system consuming 90% overnight... in deep sleep. Battery down by ~15%

I did a complete charge last night before I hit the sack. Battery was around 96%, today morning 80%!
I flashed stock ROM using TWRP, on first charge cycle battery is fine - just 1% overnight drain with 8 hrs SOT. On second charge cycle this issue hits me everytime.
All my radios are usually off (WiFi, NFC, Bluetooth, Data).
My phone seems to be in deep sleep a good portion of that time (See WLD statistics - attachment #1).
Android system sucks my battery during sleep and it was at 90% relative consumption when I woke up (See screen shot #1, Android sys has consumed 1840mAh!! This is ridiculously high for a phone that is apparently in Deep Sleep!)
Also attached screen shots from WLD for Summary, Kernal / Partial wakelocks & Alarms.
Device is rooted.
Going crazy trying to find out what's happening.
This happened with KangVIP and my current B180 ROM's which have great battery life as reported by other users here .

After you flased the ROM did you factory reset?

This is an unacceptable level of drain. I get similar numbers. This is getting very annoying. I am spending hours just debugging this nonsense.
When did you install / reset your ROM? What is the build you are on? I have read some posts that suggest to let the system be for first few days since it is in a "Learning Phase". Mine is currently in that phase.
Also, I find that many users here are not facing this issue on the ROM's that I am on, but some users are. I have faced this in multiple different ROM's.
Hence, I suspect this is an issue of some setting that we have changed. This is the first thing I do after reset / flash - modify a bunch of settings.
After searching and reading a lot, I have not come across any solid solutions from anywhere.
Here's a solution from the other thread. But I don't have this in system/apps. So this goes down the drain.

Couple others that are worth mentioning,
1. WiFi causing the drain (Am currently debugging this, modifying options).
2. Format SD card on new ROM, or just remove it (Would be great if you could try this out).
3. Factory reset has not solved for most people, but for some. (Did they *not* tweak some setting after reset?)
4. I think much of this drain is experienced after, charging and during sleep after that!

This is an unacceptable level of drain. I get similar numbers. This is getting very annoying. I am spending hours just debugging this nonsense.
When did you install / reset your ROM? What is the build you are on? I have read some posts that suggest to let the system be for first few days since it is in a "Learning Phase". Mine is currently in that phase.
Also, I find that many users here are not facing this issue on the ROM's that I am on, but some users are. I have faced this in multiple different ROM's.
Hence, I suspect this is an issue of some setting that we have changed. This is the first thing I do after reset / flash - modify a bunch of settings.
After searching and reading a lot, I have not come across any solid solutions from anywhere.
Here's a solution from the other thread. But I don't have this in system/apps. So this goes down the drain.
Couple others that are worth mentioning,
1. WiFi causing the drain (Am currently debugging this, modifying options).
2. Format SD card on new ROM, or just remove it (Would be great if you could try this out).
3. Factory reset has not solved for most people, but for some. (Did they *not* tweak some setting after reset?)

I'm on stock B192, been there for a few weeks now... didn't factory reset after the update, didn't have this issue during the first few weeks. Just recently. I haven't modified anything out of the ordinary.

What value do u have for WiFi -> Advanced -> Keep WiFi on During sleep?
I had the battery drain till last night. Before sleeping I charged it completely, and modified this WiFi setting. Overnight I had only 2% drain as compared to +15% over last few days.
Battery looks good for now. I had the feeling that my WiFi is consuming more power than 4G (Need to verify if I am right). Currently observing.
I hope it is not one of those sporadic issues!

I presume u have been facing this issue at least over past few days now, not just a day or two.
Try toggling to Never. Recharge to full before you hit the sack. Lets see if that changes anything. This helped me, but need to observe for multiple consecutive days.

Will do tonight, thanks for the advice.

If you not absolutely needed, switch OFF Google synchronisation. Profiles - Menu - uncheck auto synchronisation.

That's one of the first few things I disable. Nor do I use backup.

The battery drain is back. Disappeared for just a couple of days.
Is there anyone who knows how to fix this issue?

I would request you to do a back up of your apps and then factory reset and then again flash the ROM but via dload method.
Everything will be fine.
Then you can restore your apps
